[0002] Automotive parts processing is a process that uses specific equipment to perform different processing operations on automotive parts according to requirements. Among them, the punch press is one of the commonly used pieces of equipment in the automotive parts processing process.

[0003] The processing of existing tubular automotive parts also frequently uses punching equipment. However, traditional punching equipment relies solely on clamping and fixing the outer wall of the tube when punching tubular parts. This often leads to deviations in the punching process due to unstable clamping of the tube during the punching process. In severe cases, it can even affect the use of the tube and cause unnecessary product waste. Utility Model Content

[0004] In view of this, the present invention provides a punching machine for processing automotive parts, which can achieve a firm, stable and efficient punching operation on the workpiece by using a clamping and positioning mechanism in conjunction with a punching mechanism, ensuring the accuracy of workpiece processing and punching, and making the operation more convenient and efficient.

[0005] To solve the above-mentioned technical problems, this utility model provides a punching press for processing automotive parts, including a frame, on which a punching mechanism and a clamping and positioning mechanism are arranged. The punching mechanism includes telescopic push rods respectively arranged on both sides of the workpiece to be punched on the upper part of the frame. Each telescopic push rod has a mounting plate at its output rod end, and each mounting plate has a drill bit at both ends. The clamping and positioning mechanism includes a bidirectional drive assembly arranged at both ends of the frame and between the two mounting plates. A pair of opposing pressing pins are arranged on the bidirectional drive assembly. A support assembly is arranged on the frame below the pressing pins. This utility model can achieve a firm clamping and fixing of the workpiece to be punched through the clamping and positioning mechanism, and together with the punching mechanism, it can achieve punching operation, which is more stable and efficient. It solves the problem that when traditional punching equipment punches pipe parts, it only relies on clamping and fixing the outer wall of the pipe. This often leads to deviations in punching due to unstable pipe clamping during the punching process, which can even affect the use of the pipe and cause unnecessary product waste.

[0006] Springs are installed at both ends of the mounting plate, located on the outside of the drill bit. A clamping seat is installed at the end of each spring, and a through hole larger than the outer diameter of the drill bit is opened on the clamping seat. The drill bit passes through the through hole, which is located on the same axis as the spring. This invention allows the clamping seat to be used to pre-press and fix the workpiece near the drilling location by using the restoring force of the spring after compression before drilling. Furthermore, the clamping seat can be used to firmly clamp the workpiece during the drill bit retraction process after drilling, making the operation more stable and convenient.

The springs 400 after compression are pushed by the restoring elasticity of the springs 400. Moreover, after drilling is completed, the clamping seat 500 can be used to firmly clamp the workpiece during the retraction of the drill bit 230, making the operation more stable and convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 2As shown, the bidirectional drive assembly 310 includes a drive component 311 mounted on the frame 100. The drive component 311 is a servo motor. A bidirectional screw 312 is provided at the end of the output shaft of the drive component 311. Both ends of the bidirectional screw 312 are threadedly connected to corresponding sliding plates 313. The two sliding plates 313 are respectively provided with threaded holes with opposite threads. A guide rod 314 is also provided on the frame 100. The sliding plates 313 are provided with guide holes that are adapted to the guide rod 314. The guide rod 314 passes through the guide holes located on the same axis. The extrusion pin 315 is fixed together with the slide plate 313 located on the same side.

With the support slot, a firm and stable support operation is achieved on the bottom of the workpiece to be punched, which greatly improves the stability performance of the drilling mechanism.

[0028] How to use this utility model:

[0029] First, it needs to be clarified that the punch press involved in this utility model is mainly used for punching various pipe parts. This utility model takes the punching of pipe parts in automotive components as an example to illustrate its usage method in detail, so as to facilitate the stable and efficient punching operation for installing sensors and other parts. When it is necessary to punch the key part to be processed, the operator first places the part to be punched in the support groove on the arc support plate 321. Then, the operator starts the output shaft of the drive component 311 to rotate. The rotation of the output shaft of the drive component 311 drives the bidirectional screw 312 to rotate together. In addition, the guide rod 314 and the slide plate 313 provide guidance and limit, and the bidirectional screw 312 and the slide plate 313 are connected by threads. The rotation of the bidirectional screw 312 drives the slide plate 313 to move towards each other, along with the pressing pin 315 at the end of the slide plate 313, to realize the workpiece to be punched. The clamping and fixing operation is performed by first extending the output rod of the telescopic push rod 210 until it pushes the spring 400 to push the clamping seat 500 to achieve the clamping and fixing operation of the side wall of the workpiece to be punched. Before drilling the workpiece, the spring 400 is compressed and then pushed by the restoring force of the spring 400 to push the clamping seat 500 to achieve the clamping and fixing operation near the drilling position on the outside of the pipe. As the output rod of the telescopic push rod 210 extends, it pushes the drill bit 230 to achieve the punching operation of the workpiece, thus completing the drilling operation. Then, the output rod of the telescopic push rod 210 is retracted. During the retraction of the drill bit 230, the clamping seat 500 is used to achieve the firm clamping operation of the workpiece. This utility model can achieve a firm, stable and efficient punching operation of the workpiece by using the clamping and positioning mechanism 300 in conjunction with the punching mechanism 200, ensuring the accuracy of the workpiece processing and punching, and making the operation more convenient and efficient.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.
