Do you know what are the classifications of die stamping processing methods?

According to the different processing methods of the product, the mold can be divided into five categories: punching and shearing die, bending die, drawing die, forming die and compression die.

a.Punching and shearing die: It is to complete the work by shearing, and the commonly used forms are shearing die, blanking die, punching die, trimming die, whole edge die, drawing die and punching die.

b.Bending die: It is to bend the flat blank into an angle shape, depending on the shape, precision and production volume of the part, there are many different forms of molds, such as ordinary bending die, cam bending die, crimping die, arc bending die, bending stamping die and twisting die, etc.

c.Pumping mold: Drawing mold is to make a flat blank into a seamless container with a bottom.

d.Forming die: refers to the use of various local deformation methods to change the shape of the blank, its forms include convex forming die, coiled forming die, neck shrinking forming die, hole flange forming die, round edge forming die.

e.Compression die: It is the use of strong pressure to make the metal blank flow deformation into the desired shape, its types include extrusion die, embossing die, embossing die, end pressure die.

Compared with castings and forgings, pressing parts have the characteristics of thinness, uniformity, light and strength. Stamping can be used to produce workpieces with stiffeners, ribs, undulations or flanges that are otherwise difficult to manufacture to improve their rigidity. Due to the use of precision molds, the accuracy of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and the holes and bosses can be stamped.

Cold stamped parts are generally no longer machined or require only a small amount of machining. The accuracy and surface condition of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting is less. Stamping is an efficient production method, the use of composite die, especially multi-station progressive die, can be completed on a press (single station or multi-station stamping process), to achieve from strip uncoiling, leveling, blanking to forming, finishing of the fully automatic production.

High production efficiency, good working conditions, low production cost, generally can produce hundreds of pieces per minute. Compared to other methods of machining and plastic machining, stamping has many unique advantages, both technically and economically.

Punching, blanking, bending (hemming, curling belong to this), stretching, that's pretty much it.

There are many types of stamping dies, which can be classified according to the following rules.

1. Classification according to the stamping process.

1.The 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.

4.The forming process is called forming die, including undulating forming die, flanging die, shaping die, expansion die, shrinking die, etc.

5.The volume stamping process includes imprinting die and cold extrusion die.

Second, according to the combination of process classification.

1.Single-process die: A die in which only one process is completed under one stroke of the press.

2.Progressive die: Progressive die is also known as progressive die.

It is a continuous stamping die. In the workpiece part of the mold, it is divided into a number of equidistant stations, and after the strip material is stamped continuously along the station, the stamping of various different processes is completed, and a qualified part or semi-finished product can be punched out in the final process.

3.Composite die: Composite die is a die that uses a stroke of the press to complete more than two processes in the same position of the die.

3. Classification according to the mold-oriented form.

1.Open die: A die without guidance.

2.Guide pillar mold: The upper and lower molds of the mold are guided by the guide pillar and guide bushing.

3.Guide die: A stamping die that uses a guide plate to guide.

Fourth, according to the degree of automation of die stamping.

It can be divided into manual operation die, semi-automatic die and automatic die.

5. Classification according to production adaptability.

According to factors such as production batch, the die can be divided into two types: general die and special die.

6. Classification according to mold materials.

It can be divided into metal die, rubber die, plastic die, and powder metallurgy die.

1. Hand grinding and polishing.

The traditional mold surface processing method mainly relies on the experience and technology of the operator, and the manual polishing is more time-consuming, inefficient, and some more complex curved surfaces or hook seam grinding and polishing will be more difficult to handle.

2. Machining - CNC milling machine.

In this stamping die processing surface processing method is not processed by fast efficiency, and the processing is excellent, except for the cavity with internal acute angles and the extremely narrow and deep cavity, other aspects can be competent. It has become the mainstream process of stamping die processing in foreign countries, and China is also actively developing.

3. Machining - grinding.

Commonly used grinding equipment includes surface grinders, internal and external cylindrical grinders, and tool grinders. In order to ensure accuracy, CNC processing is generally selected. According to the shape of different parts to choose the appropriate type of grinder, plate parts choose surface grinder, cambered and rotary surface parts use internal and external cylindrical grinder or tool grinder.

Summary. Hello, the common stamping dies are: punching dies, bending dies, drawing dies, forming dies, riveting dies.

Stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, which is called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to produce separation or plastic deformation, so as to obtain the required parts.

Jinyang hardware stamping die division according to the nature of the process is divided into:

1. Continuous engineering hardware and punching: the feeding strip is in a continuous state in the stamping process, and the feeding installation is used to move the strip one pound section interval after another to use a large number of rapid consumption methods, which can be subdivided into punching continuous die, including continuous punching die of bending engineering, and three types of continuous punching die.

2. The conveying engineering stamping die is also one of the ways of continuous stamping processing, and the large feature of the continuous stamping die is that the blank is in a separate state during the stamping process, and the feeding pitch set by the robot hand buttocks or the Wei delivery mechanism is moved one by one, and the punch consumption of the product is completed after multi-station engineering!

3. Single-project stamping die: the application of the first station die to complete the required stamping operation, is a simple stamping die in structure, most of which are operated manually!

4. Hardware stamping die of the restoration project: the two groups of punches and the mother die of the upper and lower phases of the single-station mold are used to complete two or more stamping processing, which is a stamping die with good dimensional accuracy control of the product!

The processing process is based on the production needs to the material to agree on the steel, after the steel is ordered, the four-sided test tolerance is carried out after the material is opened, and the small details after the detection, such as the production of small accessories, can be directly taken to the punch, and then milled or CNC machining.

These have a lot of such details in the production of eyewear accessories and auto parts. The container is almost cut, and then the punch can be directly taken to weld, and then the sanding and then start to spray oil, and then assemble some accessories to ship perfectly.
