What are the uses of the positioning parts of the stamping die?

As far as we know, the positioning parts are the parts that determine the installation position of the blank, including positioning pins (plates), retaining pins (plates), guide pins, guide plates, fixed-distance side knives, side presses, etc. Pressing, unloading and discharging parts Pressing, blanking parts include hemming rings, pressing plates, etc. The crimping ring applies a pressing force to the drawing blank, thus preventing the blank from arching under tangential pressure and forming wrinkles.

The function of the blank is to prevent the blank from moving and bouncing. The function of the ejector and stripper is to facilitate the dispensing and cleaning of the scrap. They are supported by springs, rubber, and an air-cushion pushrod on the device for up and down movement.

Guide parts Guide pillars and guide bushings are one of the most widely used guide parts. Its function is to ensure that the convex and concave die has an accurate fit clearance during stamping work.

Supporting and clamping parts It includes upper and lower templates, die handles, convex and concave die fixing plates, backing plates, and limiters.

Wait; The upper and lower templates are the basic parts of the stamping die; Various other parts are mounted and fixed on it separately. Fastening parts It includes screws, nuts, springs, pins, washers, etc. In general, standard parts are used. <>

As far as we know, the parts in the fixture should coincide with the design datum and the process datum, and be positioned according to the six-point positioning principle. For example, punching a washer can be completed with two sets of molds respectively punching and blanking, punching is punching the hole in the middle, and blanking is punching out the shape; If it is done at one time with a pair of molds, it is a composite mold. Make a semi-circular ball die, the bottom opening is convenient for chip removal, to avoid punching the mold, pay attention to the stamping strength of the die generally need a positioning device better, our company used to position it like this, very practical and simple.

The center point is positioned to the punching center point, depending on the machine. The product stands up and rushes. <>

As far as we know, stamping dies can be divided into three categories: single engineering dies, composite dies and continuous dies according to their structure. Mould holder plate: The front mould is fixed on the injection molding machine.

Runner plate: Remove the scrap handle when opening the mold, so that it will fall off automatically. Fixed Mold:

The front mold part of the molded product. Moving mold fixing plate: the part of the molded product after molding.

Pad block: Mould foot, its function is to let the top plate have enough space to move. Push Plate:

When the mold is opened, the product is pushed out of the mold by pushing out parts such as ejector rods, ejector blocks, and inclined tops. Moving Mold Base Plate: Fix the back mold on the injection molding machine.

Guide pillar and guide bushing: play the role of guiding positioning, assist the front and rear mold opening, and mold and basic positioning. Support columns:

Improve the strength of the B plate, and effectively avoid the deformation of the B plate caused by long-term production. Roof guide pillar: guide and position the push plate to ensure smooth ejection.

Heju precision stamping die processing equipment: including AgieCharmilles slow wire cutting, Japanese original Sodick slow wire cutting, oil cutting machine, Taiwan precision grinder, Japan AMADA Vasino optical curve grinder, precision image measuring instrument, projector, hardness tester, etc. The positioning part of the action die is used to control the correct feeding of the strip and the correct position of the individual blanks.

For strips. The so-called control of correct feeding is to control the feeding direction and feeding step. Retaining pins.

Side edges. The positioning part of the action die is used to control the correct feeding of the strip and the correct position of the individual blanks. For strips.

The so-called control of correct feeding is to control the feeding direction and feeding step. Retaining pins. Side edges.

Positive pins. Structural parts, such parts do not directly participate in the completion of the process, nor do they have direct contact with the blank, but only play a role in ensuring the completion of the process of the mold, or play a role in improving the function of the mold, including guide parts, fastening parts, standard parts and other parts, as shown in the table. It should be noted that not all dies must have the above six types of parts, especially single-process dies, but working parts and necessary fixed parts are indispensable.

Hello pro According to the situation you described, 1The punching process is called a blanking die, including blanking die, punching die, cutting die, cutting die, cutting die, trimming die, trimming die and fine blanking die. 2.

The bending process is called bending die, including compression bending die, pull bending die, twisting die, crimping die, etc. 3.The deep-drawing process is called a deep-drawing die, including a single-side deep-drawing die, a double-action deep-drawing die and a thinning deep-drawing die.

1. The die handle is used to fix the upper template, and the die handle is installed on the punch slider, and the upper die is driven by the slider to carry out punching work; 2. The upper template is used to touch and connect and fix the punch fixing plate (that is, the pressure plate of 6 The guide pillar and guide sleeve are used to correct the gap between the punch and the die, ensure the noisy size gap of the mold, and avoid the punch and the die gnawing; 5. The lower template is used to fix the die and fix the die on the working surface of the punch press; 6. The pressing plate, also called the punch fixing plate, is used to fix the punch; 7. The die is hidden, which is the main working piece of the gap blanking operation with the punch; 8. The die sleeve plate is used to fix and strengthen the die; 9. The guide plate is used to guide and position the stamping parts to ensure that the left and right dimensions of the stamping parts meet the requirements of the drawings; 10. Punch, punching operation together with the die; 11. The positioning nails in the front direction ensure the size of the front and rear directions of the stamping parts; 12. The stripper is used to remove the stamping scrap sleeved on the punch.

The forming die is generally edge positioning, the trimming die is generally positioned by the shape, the shaping die is especially the hole positioning of the beam shape, according to the complexity of the part, the reasonable selection of positioning, the shape and the edge positioning are coarse positioning, and the hole is fine positioning.

According to the product structure, there are process holes, edge positioning, and 3D mold core positioning.

The center point is positioned to the punching center point, depending on the machine.

Generally speaking, it is better to need a positioning device, make a semi-circular ball die, the bottom opening is convenient for chip removal, and it is necessary to pay attention to the stamping strength of the die to avoid damaging the die.

Reservation of process edge or process hole, or positioning by shape, should be determined according to the actual situation.

Mechanical Wolf has the answer for you.

Supporting and clamping parts: it includes upper and lower templates, die handles, convex and concave die fixing plates, backing plates, limiters, etc.; The upper and lower templates are the basic parts of the stamping die; Various other parts are mounted and fixed on it separately. The plane size of the template, especially the front and rear directions, should be suitable for the workpiece, and too large or too small is not conducive to operation.

Some molds (blanking, punching molds) need to be set up under the mold base for the convenience of delivery. At this time, it is best to connect the backing plate with screws between the backing plate and the template, and the thickness of the two backing plates should be equal. The spacing of the backing plate is subject to the ability to produce parts, not too large, so as not to break the template.

In the production of automotive stamping parts, compared with cold stamping, the hot stamping process can effectively balance the problems of lightweight and crash safety, as well as rebound of stamping parts and die wear under high strength, and has attracted attention. Hot stamping processing should be realized through its forming die, and whether the design of the die is reasonable will be directly related to the efficiency of hot stamping.

When designing the structure of the hot stamping mold, the main considerations include: the layout of the insert cooling system, the strength of the mold, the tightness of the mold, etc. Among them, the most important is the arrangement of the insert cooling system to ensure that the hot stamping part has a certain cooling rate after forming.

Stamping is one of the practical processes for the production of high-volume parts molding. In the stamping production process, the die has the most problems, and it is the most important factor in the entire stamping production factor. It has a direct impact on production efficiency and costs.

Affect the lead time of the product. Mold problems are mainly focused on mold damage, product quality defects and mold sharpening, which have plagued industry production for a long time. Only by getting these few key points right.

Stamping production can be carried out smoothly. Mold damage refers to mold cracking, breaking, swelling, etc., to deal with the problem of mold damage, we must find the cause from the design, manufacturing process and use of the mold. First of all, it is necessary to check whether the manufacturing materials of the mold are suitable and whether the corresponding hot burial process is reasonable.

In general, the heat treatment process of the mold material has a great influence on it. If the quenching temperature of the mold is too high, the quenching method and time are unreasonable, and the tempering times, temperature, and elbow selection are improper, it will cause damage to the mold after entering the stamping production. The size or depth of the blanking hole is not designed enough, which is easy to block the slot hole and cause damage to the blanking plate.

If the spring force design is too small or the contour sleeve is not of equal height, the spring will break and the blanking plate will tilt. Causing overlapping punches and damaging parts. Improper fixing of the punch or insufficient screw strength can cause the punch to fall or break.

When the mold is used, the position and orientation of the parts are installed incorrectly or the bolts are not tightened well. The working height adjustment is too low, and the guide pillar is not lubricated enough. Faulty feeding equipment, abnormal presses, etc., will cause damage to the mold.

If foreign objects enter the mold, parts overlap, waste blockage and other situations are not dealt with in time, and continue to process and produce, it is easy to damage the blanking plate, punch, lower plate and guide pillar of the mold.

Your question is really big.

Stamping dies are divided into steel plate dies and casting dies.

The steel plate mold has a forming die, a trimming punching die, a flanging touch, a bending die == a casting mold and a drawing die, a trimming punching die, a flanging touch, an oblique wedge die == Look at your description, you want to know the accessories of the general steel plate mold.

Generally, the forming die of the steel plate mold is composed of the upper and lower templates, the backing plate, the punch, the concave die, and the mold handle =.

The trimming punching die consists of the upper and lower templates, backing plates, punches, die sleeves, trimming inserts, pressing cores, springs = others are not detailed, it is best to find this "stamping technology" to see, there is the most basic mold structure.

A small problem, the area covered is too large! The mold is designed according to different rules to add suitable accessories! The most basic, like screws, fastening, springs.

It has a discharge function, and also has other uses. All the accessories you refer to are when even a piece of scrap metal can come in handy! No one can say it all!
