Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stamping equipment, in particular to an integrated structure for trimming and forming of stamped parts. Background Technique
[0002] Stamped parts are a common type of parts in industrial production and are widely used in multiple fields such as automobiles, household appliances, and electronics. Stamping processing is to apply external force to sheets, strips, etc. through a press and a die, so that they undergo plastic deformation or separation, thereby obtaining workpieces with the required shape and size. In the processing of stamped parts, trimming and forming are two important links. The main purpose of trimming is to remove excess material to obtain an accurate part contour; while forming is to make the material undergo plastic deformation through a die to form the required part shape.
[0003] Traditionally, the trimming and forming of stamped parts are often two separate processes carried out separately. First, the parts are separated from the sheet material through a blanking or shearing process, and most of the excess material is removed; subsequently, the preliminarily formed parts are placed in another set of dies for shaping to meet the final dimensional and shape requirements. Although this step-by-step processing method is technically mature, there are obvious efficiency bottlenecks. Each additional process means more equipment, manpower, and time investment, and at the same time increases the risk of errors and production costs.
[0004] To sum up, the process of removing the strip material and shaping the stamped parts separately in the prior art has the problem of low efficiency. Developing a device that can solve both strip cutting and shaping at the same time is a technical problem that needs to be urgently solved by those skilled in the art. Content of the Utility Model
[0005] In view of the problems existing in the background technique, the utility model provides an integrated structure for trimming and forming of stamped parts, which realizes the cutting and forming of the strip material in one process by inheriting a cutting device and a shaping device. The device includes a forming female die, a blank holder, and a trimming and forming part. The forming female die serves as the base of the entire device, and the workpiece to be processed is placed on the forming female die. The blank holder presses the workpiece to be processed from top to bottom, and the trimming and forming part is arranged at the rear end of the forming female die and moves from bottom to top to complete the cutting and forming processes of the strip material of the workpiece to be processed.
[0006] Further, the trimming and forming part includes a trimming and forming male die and a trimming and forming female die. When the trimming and forming part works from top to bottom, the trimming and forming male die first contacts the workpiece to be processed to cut the strip material of the workpiece to be processed, and then the trimming and forming female die continues to move downward to form the workpiece to be processed.
[0007] Further, the trimming and forming punch is disposed inside the trimming and forming die. A groove is provided at the rear of the trimming and forming punch, and a convex rib is provided at the front of the trimming and forming die. The convex rib is clamped in the groove, and the trimming and forming punch can move up and down along the trimming and forming die.
[0008] Further, a stepped notch is provided at the rear end of the blank holder. A stepped notch corresponding to the stepped notch of the blank holder is provided at the lower part of the front end of the trimming and forming punch. When the trimming and forming punch moves downward, the stepped notches of the blank holder and the trimming and forming punch engage with each other. At this time, the trimming and forming punch automatically stops when it reaches the working position, and the forming die continues to move downward.
[0009] The advantages and beneficial effects of the present utility model are as follows: The present utility model simultaneously completes the cutting and shaping of the strip material of the stamping part through one process, greatly shortening the production process and reducing the conversion time between processes, thereby significantly improving the production efficiency. The integrated structure design enables the cutting and forming processes to be more accurately docked, reducing problems such as dimensional deviation and inaccurate shape, thus improving the quality of the final product. This structure is more conducive to realizing automated production, can improve the automation level of the production line, and further enhance the production efficiency and product quality.

[0015] As Figure 1 and Figure 2 shown, an integrated structure for trimming and forming of stamping parts, the device structure mainly includes the following components: a forming female die 1, a blank holder 2, and a trimming and forming part 3.
[0016] The forming female die 1 serves as the base of the entire device and has a supporting function, and the workpiece to be processed is placed on it.
[0017] The blank holder 2 is designed to move up and down. Its main function is to press the workpiece to be processed from top to bottom to ensure that the workpiece to be processed remains stable during processing and avoid displacement or deformation.
[0018] The trimming and forming part 3 is arranged at the rear end of the forming female die 1, and its working direction is to move from bottom to top to cut and form the strip of the workpiece to be processed. The trimming and forming part 3 includes a trimming and forming punch 31 and a trimming and forming die 32.
[0019] When the trimming and forming part 3 works, the trimming and forming punch 31 will first contact the workpiece to be processed and cut its strip. The trimming and forming punch 31 is arranged inside the trimming and forming die 32, and a groove is opened at its rear part for clamping and cooperating with the convex rib at the front part of the trimming and forming die 32, so that the trimming and forming punch 31 can move up and down along the trimming and forming die 32.
[0020] After the trimming and forming punch 31 completes the cutting action, the trimming and forming die 32 continues to move downward to form the workpiece to be processed. The convex rib at its front part is clamped and cooperated with the groove at the rear part of the trimming and forming punch 31 to ensure the coordination between the two during the working process.
[0021] A stepped notch is designed at the rear end of the blank holder 2, and a corresponding stepped notch is also provided at the lower part of the front end of the trimming and forming punch 31. The notch can ensure that the trimming and forming punch 31 can automatically stop when it reaches the working position, while the trimming and forming die 32 continues to move downward. When the trimming and forming punch 31 moves downward, these two stepped notches will engage with each other, thus realizing the automatic stop of the trimming and forming punch 31 and the continuous downward movement of the trimming and forming die 32.
[0022] Specific usage steps:
[0023] During use, first place the workpiece to be processed on the forming die 1. Then, start the equipment, and the blank holder 2 will press the workpiece from top to bottom to fix it. Next, the trimming and forming part 3 starts to work. The trimming and forming punch 31 first contacts the workpiece to be processed and cuts off the strip. When the stepped notch of the trimming and forming punch 31 engages with the stepped notch of the blank holder 2, the trimming and forming punch 31 automatically stops. At this time, the trimming and forming die 32 continues to move downward to form the workpiece to be processed. This structure completes the cutting and forming of the strip in one process, significantly improving the production efficiency and product quality.
[0024] The above has introduced in detail a trimming and forming integrated structure for stamping parts provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention.
