[0002] A stamping machine, also known as a punch press, is a piece of equipment used in the forging industry. It has great versatility, simple structure, and easy adjustment and maintenance. Stamping production is mainly for plates. During the stamping process, in order to prevent the material from shifting and causing the workpiece produced to fail to meet the standards, a positioning structure is required to limit the positioning of the material.

[0003] When the existing stamping machine positioning structure is used, baffles are usually set on both sides of the die base to position and maintain the position of the stamping part. The baffles are usually fixed with bolts, which is easy to cause interference when the die is replaced later, affecting the efficiency of replacement. In addition, the size of most baffles is fixed. When adjusting the size according to the mold, it is usually necessary to use tools to replace the new baffle, and the steps are relatively cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-3 As shown, a punching machine with a positioning structure comprises a base 1, a support frame 2 is fixedly connected to the top of the base 1, a hydraulic cylinder 3 is installed at the center of the top of the support frame 2, and a positioning assembly 6 is arranged at the top of the base 1;

[0023] The push rod of the hydraulic cylinder 3 passes through the upper and lower ends of the support frame 2 and is connected to a punch head 4. A punch seat 5 is installed at the center of the top of the base 1. The positioning assembly 6 has an adjusting threaded rod 7. The top of the base 1 is provided with a mounting groove that matches the adjusting threaded rod 7, and the adjusting threaded rod 7 is rotatably installed in the mounting groove. The outer ring of the adjusting threaded rod 7 is threadedly connected to movable blocks 8 on both sides. The tops of the two movable blocks 8 are fixedly connected with connecting blocks 9. The top of the connecting block 9 is rotatably installed with a limited clamp block 10 through a rotating rod.

[0024] In this embodiment, a limiting clamp block 2 12 is arranged at the top of the limiting clamp block 10, and the bottom end of the limiting clamp block 2 12 is fixedly connected with an insertion rod 13 at the front and rear end positions, and the limiting clamp block 2 12 and the top of the limiting clamp block 10 are both provided with insertion holes matching the insertion rod 13. By inserting the limiting clamp block 2 12 into the limiting clamp block 10, the limiting clamp block 10 can be increased in height to ensure that the limiting clamp block 2 12 cooperates with the limiting clamp block 10, and the two sides of the stamping part can be limited and positioned.

[0025] In this embodiment, a locking nut 11 is threadedly connected to one side of the rotating rod of the limit clamp 10, and the limit clamp 2 12 and the side of the limit clamp 10 close to the stamping seat 5 are both provided with anti-slip textures. By loosening the locking nut 11, the lock of the limit clamp 10 can be released, and then the limit clamp 10 can be rotated to adjust its angle. The anti-slip texture can increase the friction between it and the workpiece to be stamped and reduce the probability of sliding.

[0026] In this embodiment, the outer ring of the adjusting threaded rod 7 is provided with two sections of threads of the same length and opposite directions. The movable block 8 is threadedly connected to the adjusting threaded rod 7, and the base 1 is slidably connected to the connecting block 9 and the movable block 8. By rotating the adjusting threaded rod 7, the thread pushes the two limit clamps 10 away from and close to each other, so as to adjust according to the width of the workpiece to be stamped, facilitate clamping and positioning of the workpiece to be stamped, and avoid displacement of the material during the stamping process.

[0027] In this embodiment, an adjusting motor 14 is installed on one side of the base 1. The driving shaft of the adjusting motor 14 passes through one side of the base 1 and is connected to one end of the adjusting threaded rod 7. The driving shaft of the adjusting motor 14 is rotatably connected to the base 1. The adjusting threaded rod 7 can be driven to rotate by rotating the driving shaft of the adjusting motor 14, which is convenient for transmission. The driving shaft of the adjusting motor 14 is rotatably connected to the base 1 to avoid interference of the base 1 on the adjusting motor 14.

[0028] In this embodiment, the top end of the limiting clamp 12 does not contact the punch head 4, and a handle groove is provided at the end of the limiting clamp 12 away from the punch seat 5. The handle groove makes it easy to lift the limiting clamp 12, and the limiting clamp 12 does not contact the punch head 4 to avoid collision damage.

[0029] It should be noted that the utility model is a punching machine with a positioning structure. When in use, first, when clamping the punching piece, the punching piece is placed on the punching seat 5, and the two limit clamps 10 are threadedly connected to the adjusting threaded rod 7 through various components, and the limit clamps 10 are located on both sides of the punching seat 5. At the same time, the adjusting threaded rod 7 is provided with two sections of threads of the same length and opposite directions, so that the two limit clamps 10 can be pushed away from and close to each other by the adjustment motor 14 driving shaft to rotate, so as to adjust according to the width of the punching piece to be punched, so as to facilitate the clamping and positioning of the punching piece to be punched, avoid the material from being offset during the punching process, reduce the probability of substandard production quality, and improve the stability of the punching process;

[0030] When the height of the stamping part and the stamping seat 5 is relatively high, since the limiting clamp block 10 is provided with a plug hole that matches the insertion rod 13, the limiting clamp block 2 12 can be inserted into the limiting clamp block 10, which can increase the height of the limiting clamp block 10, so as to ensure that the limiting clamp block 2 12 cooperates with the limiting clamp block 10, and the two sides of the stamping part can be limited and positioned to avoid its skew;

[0031] At the same time, when the stamping seat 5 is replaced according to the actual situation of the stamping part, since the limit clamp block 10 is rotatably connected with the connecting block 9, the lock of the limit clamp block 10 can be released by loosening the locking nut 11, and then the limit clamp block 10 can be rotated to adjust its angle, and according to the above steps, after fine-tuning the angle, the distance between it and the stamping seat 5 can be adjusted to avoid the limit clamp block 10 causing greater interference to the installation of the stamping seat 5, which is convenient for improving the replacement efficiency, and the adjustment process of the limit clamp block 10 does not require frequent installation and disassembly, which is convenient for reducing the tedious steps of personnel operating back and forth.
