What are the classifications of stamping dies and stamping dies

There are many forms of stamping dies, which can generally be classified according to the following main characteristics: (1) Punching dies that produce separate dies along closed or open contour lines. Such as blanking die, punching die, cutting die, cutting die, cutting die, trimming die, cutting die, etc.

2) Bending die is a mold that makes the sheet blank or other blanks bend and deform along the straight line (bending line), so as to obtain a workpiece with a certain angle and shape.

3) Drawing die is a mold that makes the blank blank into an open hollow part, or makes the hollow part further change its shape and size.

4) Forming die is a mold that directly copies the blank or semi-finished workpiece according to the shape of the convex and concave die in the drawing, and the material itself only produces local plastic deformation. Such as expansion die, shrinking die, flaring die, undulating forming die, flanging die, shaping die, etc. (1) Single-process die In a stroke of the press, only one stamping process is completed in the mold.

2) Composite die There is only one station, and in one stroke of the press, two or more stamping processes are completed at the same time on the same station.

3) Progressive die (also known as progressive die) In the feeding direction of the blank, there are two or more stations, in one stroke of the press, in different stations to complete two or more stamping processes one by one.

4) Transfer mold integrates the characteristics of single-process mold and progressive mold, and uses the manipulator transfer system to realize the rapid transfer of products in the mold, which can greatly improve the production efficiency of products, reduce the production cost of products, save material costs, and the quality is stable and reliable. Typical structure of the mold:

The figure shows a single-process punching die with a guide pillar and guide bushing. The upper die is made up of two parts, and the upper die is made up of parts such as die handle 5, upper die holder 3, guide bushing 2, punch 10, backing plate 8, fixing plate 7, stripper plate 14 and screw, pin; The counterdie is made up of parts such as the counterdie base 17, the guide pillar 1, the concave die 11, the material guide plate 15, the material bearing plate 18 and the screw, the pin. The upper die is installed on the press slider by the die handle 5, and the slider moves up and down with the slider, so it is called the movable part.

The lower die is fixed on the press table through the lower die base, so it is also called the fixed part.

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.

Summary. Hello, I am glad to answer for you: the difference between molding and stamping: generally plastic molds and die-casting molds can have sliders. These two cannot be done together, the process is different, and the machines used are also different.

Difference Between Compression Forming and Stamping.

Hello, I am glad to answer for you: the difference between molding and stamping: generally plastic molds and die-casting molds can have sliders. These two cannot be done together, the process is different, and the machines used are also different.

The difference between stamping and stamping die: stamping is a forming processing party that applies external force to plates, strips, pipes, and profiles by presses and dies to produce plastic deformation or separation, and obtain workpieces (stamping parts) of the required shape and size. Compared to castings and forgings, stamped parts.

It has the characteristics of thin, uniform, light and strong. Stamping can be manufactured with stiffeners, ribs, undulations, or other methods to increase its stiffness. At present, polyurethane rubber molds, steel skin molds, sheet molds, low melting point alloy molds, zinc alloy molds and combination molds.

Ordinary presses can produce dozens of pieces per minute. The high-speed press can produce hundreds of units per minute, which is an efficient processing method, in the trial production of new products and small batch production of stamping parts, a simple stamping structure is generally adopted, which is not only simple in structure, but also convenient to manufacture, low in cost, and can meet certain processing quality requirements.

There are many types of stamping dies, and the commonly used ones are punching dies, bending dies, forming dies, drawing dies, etc.

As far as the vertical method of stamping process is concerned, it can be summarized into two categories: separation process and forming process.

The molds of the separation process include: blanking, punching, cutting, trimming, cutting and other nuclear simplifications; The mold modification pants in the forming process are: bending, rounding, twisting, drawing, thinning and stretching, turning holes, flanging, stretching, stretching, expanding, undulating, flaring, shrinking, spinning, calibration, etc.

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!
