What are the models of the guide pillar guide bushing, and how to recognize the specifications in th

1. Definition of mold size:

The size of the mold is defined according to its length.

Second, the design standard of template thickness:

The thickness of the template is determined according to the specific situation, in order to save resources, the template adopts the principle of minimization, and the thickness standard is based on this principle by experienced designers according to the standard parts and mold structure. Therefore, the standard plate thickness is used as much as possible.

1. Progressive die template thickness standard:

2. Blanking die template thickness standard:

3. The thickness standard of the bending die template:

Guide pillar diameter 10 13 16 20 25 Guide bush is the same length 60 70 80 90 100 110 In addition, the outer diameter of the guide bush = inner diameter plus 5mm You can go to the coil up industry ** Refer to its standard Many companies in the industry are the same as him.

The diameter of the guide pillar is 10 13 16 20 25 The guide bush is the same, and the length is 60 70 80 90 100 110 In addition, the outer diameter of the guide bush = the inner diameter plus 5mm.

Guide Pillar: Guide Pillar, English Guide Rod or Guide Pin -- Mechanical Mold - Mold Terminology] Guide pillar is a guide element used in combination with components in the mold to ensure that the mold is moved with precise positioning to guide the mold stroke. The material of the guide pillar is generally made of bearing steel, hot work die steel, easy car iron, etc., and the use of bearing steel SUJ2 is larger, so that the durability and replaceability of the guide pillar in the guiding performance are greatly enhanced.

The guide pillar and the component form the outer guide pillar assembly and the inner guide pillar assembly, which has a beautiful metallic luster. Heat treatment of guide pillar: HRC58-62; Guide pillar surface roughness:

The guide pillar is generally cylindrical with shoulders, and there are generally oil grooves, and the number of oil grooves increases with the degree of the guide pillar, and the most extreme oil grooves are generally 8.

There are too many models, divided into hardware mold and plastic mold, hardware mold is divided into outer guide pillar and inner guide pillar, outer guide pillar is divided into rolling and sliding, rolling is divided into independent guide pillar and guide pillar assembly, guide pillar assembly is divided into press-in type and loading and unloading type, and what steel ball sleeve is also divided, and the plastic mold is also divided into this way.

1. Definition of mold size:

The size of the mold is determined according to its length.

Second, the design standard of template thickness:

The thickness of the formwork is determined according to the specific situation, in order to save resources, the formwork adopts the original ZD rule, and the thickness standard is based on this principle by the experienced design and modification hail planner according to the standard parts and mold structure. Therefore, the standard plate thickness is used as much as possible.

1. Progressive die template thickness standard:

2. Blanking die template thickness standard:

3. The thickness standard of the bending die template:

The guide pillar is 28 outer diameter 150 length, the guide bush is 28 inner diameter 100 length 38 outer diameter.

Steps to install the guide pillar guide bushing:

1.The guide pillar guide sleeve should be Henan Dashan non-ferrous metal to determine whether the matching surface of the shaft and the shaft shell has collisions, protrusions, etc.

2.Whether there is dust or mold sand attached to the surface of the guide pillar guide sleeve housing.

3.Even if it is a slight bruise, protrusion, etc., if any, it should be removed with an oil grinder or fine sandpaper.

4.In order to avoid bruising during installation, a small amount of non-ferrous metals and shaft shells should be wiped on the surface of the shaft Henan Dashan.

Lube. When the guide post guide sleeve is installed on the shaft, the force must be applied in the inner ring, and when the guide post guide sleeve is installed in the guide pillar guide sleeve shell, it must be in the outer ring.

Apply force. When applying force to the guide pillar and guide bushing, it is important to pay attention to making the force vertical and evenly downward, as the bias will inevitably injure the guide post guide bushing. For this reason, try to avoid bias as much as possible.

5.The retainer and sealing plate of the guide post guide sleeve must not be forced. The installation method of using Henan Dashan non-ferrous metal hammer and casing is a commonly used method, because it will damage the guide pillar and guide bushing.

Don't hit it directly. Be sure to tap the sleeve in the middle as shown in the picture. The hammer should be tapped lightly. In the structure of the machine, when the inner and outer rings are tightly fitted, the backing plate should be used, and the force must be increased at the same time.

Press it into the inner and outer rings. If it is pressed only in the inner ring, the force will be pressed into the outer ring by the ball, so it will cause scars on the track surface. When the guide pillar guide sleeve with a large margin is placed on the shaft, the guide pillar guide sleeve is heated in clean oil.

80-90 degrees, the method of making the inner diameter expand to mount, is widely used.

6.The hardness of the guide pillar and guide bushing is reduced due to overheating, so it must not exceed 100 degrees. At this point, the axis.

The bearing must be suspended with steel wire, or placed on the wire platform, support plate, do not place at the bottom of the trough. When the guide bushing reaches the desired temperature (below 100 degrees), it should be immediately removed from the groove and quickly inserted into the shaft.

On the guide pillar guide bushing will shrink with the drop of temperature, and sometimes between the shaft shoulder and the end face of the guide pillar guide bushing, there will be a gap, therefore, tools need to be used to compress the guide bushing of the non-ferrous metal guide pillar in Henan Dashan to the shaft direction.

In fact, the guide pillar of the die-casting mold is also equipped with a "moving mold".

There are bumps in the cavity part of the mold.

1. If the convex side is in the fixed mold, then it is recommended to install the guide pillar in the fixed mold part, and the length of the guide pillar must exceed the convex cavity;

2. If the convex side is in the moving mold, then it is recommended to install the guide pillar in the moving mold part, and the length of the guide pillar should also exceed the protruding cavity; In this way, in addition to the guiding function, the guide pillar can also play the function of protecting the protruding cavity of the mold from collision damage.

The moving mold is not necessarily convex, the static mold is not necessarily concave There are also many installation methods for the guide pillar guide sleeve, and the large die-casting mold and the small precision die-casting mold are different, and the plastic mold is also very different from the die-casting mold made now, and the professional buddies of the mold should be very clear.

You can install it casually Consider picking up the piece, generally put the static mold.

Our guide pillars are all installed on the moving mold, so I don't feel troublesome to assemble. The main reason for installing the mold is to protect.

Hengtongxing, as a professional mold accessories manufacturer, tells you that there are many types of guide pillars and guide bushings, and how to distribute them, for example, according to the material SUJ2 is commonly used, and it can also be divided into model specifications. In short, there are a lot. The role of the guide pillar and the guide sleeve is the guide device that composes the mold to ensure the alignment of the moving mold and the fixed mold.

There are two common types of mold guide pillars, one of which has oil grooves in the guide pillars of the guide device in order to maintain good lubrication. The inner hole of the guide bush is matched with the guide pillar and is matched in the form of sliding. This type of guide pillar is called a sliding guide pillar.

There is also a kind of guide pillar guide bushing, and the guide sleeve of the guide device is equipped with a steel ball sleeve cage to ensure accurate guidance. The inner hole of the guide bush and the guide pillar are matched in the form of balls. From the performance of the analysis of the sliding guide pillar, the length of the guide bushing pressed into the upper bottom plate and the outer diameter of the guide bushing shall not be less than the times of the diameter of the guide pillar, and the guide length of the guide sleeve shall be 2 3 times the diameter of the guide pillar.

The diameter of the guide pillar can be determined according to the mold structure, the strength and stiffness of the guide pillar. The length of the guide pillar pressed into the lower bottom plate shall not be less than the times of the diameter of the guide pillar, and the total length l of the guide pillar is determined according to the closing height of the mold, but it is necessary to ensure that when the punch enters the die before, the guide pillar extends into the guide sleeve more than 15 (mm), otherwise it can not play a guiding role.

The roundness of the guide pillar is highly demanding, and the center hole is mainly to be able to use the cylindrical grinder to grind the outer diameter, because when the cylindrical grinder is used to grind the outer diameter, the center hole should be rotated with the top to rotate the guide pillar before grinding. The angle of the inclined guide pillar of the mold is generally 20 degrees or 25 degrees, and the one of 20 degrees is generally used, and if the distance of the slider is a little long, this one of 25 degrees can be used. If the distance is longer, use hydraulic or pneumatic methods.

Guide pillars, according to the different places of use, are divided into: guide pillars for automobile molds, independent guide pillars, guide pillars for mold bases, and guide pillars for strippers. According to the different direction of guidance, it is divided into:

Sliding guide pillar (code SGP), rolling guide pillar (code SRP). According to the different installation methods, it is divided into: loading and unloading guide pillar and press-in guide pillar.
