Description

Technical Field

[0001] The utility model relates to a stamping separation die, in particular to a stamping separation die for a lower thrust rod bracket plate, and belongs to the field of automobile structural part die design. Background Art

[0002] There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing, and the market of auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. Thrust rods are commonly used in the automotive industry, and the requirements for thrust rods in auto parts are very high. The thrust rod bracket plate is an auxiliary component of the thrust rod, which plays an important role in the operation and work of the car. The left / right bracket plate of the lower thrust rod of the car is one of the indispensable parts of the car.

[0003] As the automobile industry becomes more and more sophisticated, the requirements for automobile accessories are also getting higher and higher. This requirement is not only reflected in the quality of the accessories, but also in the control of the accessory manufacturing process. In the prior art, stamping dies are usually used to process and produce the left / right bracket plates (inner or outer plates of the bracket) of the automobile lower thrust rod. Generally, the stamping die includes an upper die and a lower die. When in use, the material is placed on the lower die, and the upper die is controlled to stamp downward to separate or plastically deform the material, thereby obtaining the required parts. The lower thrust rod bracket plate is a special-shaped part composed of multiple curved surfaces (and includes left and right parts), which includes a central plate body and a bent wall on the plate body. The central plate body is provided with a matching hole groove, such as Figure 1 The structure of the lower thrust rod bracket plate is relatively complex, and multiple stamping dies are required for multiple stamping forming, including primary forming (stamping the central plate), secondary forming (bending wall, etc.), separation (separation of the left and right parts and punching, etc.) and shaping, among which stamping separation plays an important role in the production process of the entire product.

[0004] The separation process in the production process of the lower thrust rod bracket plate includes dividing the workpiece into two independent left and right plates and punching multiple holes with different inner diameters on the two separated plates. The existing stamping separation mold has a simple structure and a single function. It cannot stamp and separate all the positions that need to be separated at the same time. It requires multiple processes to complete. This not only prolongs the working cycle and greatly reduces the processing efficiency, but also requires more molds, which increases the cost. After long-term and tedious work, the operator will also cause inaccurate processing accuracy due to fatigue. In addition, the waste generated during the stamping separation process will remain in the upper mold or inside the lower mold without falling off. If these materials cannot be cleaned up in time, it will affect subsequent production.

The lower module 7 is arranged on the lower die base 6, and a blanking blade 8 for allowing the punch 5 to pass through is opened in the middle of the lower module 7. The blanking blade 8 passes through the lower module 7, and punching dies are respectively arranged on the lower modules 7 on the left and right sides of the blanking blade 8. A blanking through hole for accommodating the punching punch is arranged in the middle of the punching die, and the aperture of the blanking through hole is small at the top and large at the bottom, that is, the upper end aperture of the blanking through hole in the middle of the punching die is smaller than the lower end aperture, so as to facilitate the discharge of waste materials. The middle part of the workpiece to be processed is removed by cooperating with the blanking blade 8 and the punch 5, thereby separating the workpiece into two independent left and right plates. The matching holes are punched out on the workpiece to be processed by cooperating with the punching die and the punching punch, and the separated waste is discharged along the blanking blade 8 and the blanking through hole.

[0033] A more specific structural design is that a group of punching punches is arranged on the upper module 4 on each side of the punch 5, and each group of punching punches includes a first punching punch 9, a second punching punch 10 and a third punching punch 11, wherein the first punching punch 9 punches out a waist-shaped hole on the workpiece to be processed, and a group of punching dies is arranged on the lower module 7 on each side of the blanking blade 8, and each group of punching dies includes a first punching die 12 and a second punching die 13, wherein the first punching die 12 is used to receive the first punching punch 9, and the second punching die 13 is used to receive the second punching punch 10 and the third punching punch 11.

The lower die base 6 and the lower pad 22 are respectively provided with waste channels connecting the blanking knife edge 8 and the blanking through hole of the punching die. The waste generated by the stamping separation process is collected centrally through the waste box 26.

[0037] When using this mold, place the workpiece to be processed at a suitable position on the lower mold assembly, control the upper mold assembly 1 to move downward, the upper mold module 4 first presses the workpiece sheet, and the press continues to control the upper mold assembly 1 to move downward until the punch 5 cuts off the waste other than the product, and the waste slides out of the lower mold module 7 to the waste box 26. The machine tool rises, and the upper mold assembly 1 rises with the machine tool until the upper and lower mold assemblies 2 are completely separated. Completing the above work content means completing one punch.

[0038] The utility model is convenient and quick to install and separate workpieces, and is convenient for quickly taking out the workpieces and accurately placing them into the mold.
