For those skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific circumstances.

[0028] Please refer to Figure 1 - Figure 5 The present application provides a technical solution:

[0029] A punch for casting processing, comprising a machine body 1, in addition, the bottom of the machine body 1 is provided with a foot prop, which has been shown in the figure, so that the machine body 1 is placed more stably, the top of the machine body 1 is fixedly installed with a main punch head 2, the side wall of the machine body 1 is fixedly installed with a punch seat 3, and the punch seat 3 is located directly below the main punch head 2.

[0030] In an embodiment of the utility model, punch assembly 4 is established on organism 1, punch assembly 4 includes support 41, and the outer wall fixed mounting of organism 1 has support 41, and the outer wall fixed mounting of support 41 has asynchronous motor 42, and the output fixed mounting of asynchronous motor 42 has screw rod 43, and screw rod 43 rotates and is installed on support 41, and the screw rod 43 on screw rod 43 threadedly installs screw block 44, and screw block 44 fixed mounting is in the inner wall of mobile frame 45 bottom end, and the bottom fixed mounting of mobile frame 45 has wheel carrier 46, and wheel carrier 46 inside rotationally installs gyro wheel 47, and gyro wheel 47 rolls and is attached to support 41 inside, in addition, wheel carrier 46 and gyro wheel 47 are provided with two groups, and two groups of wheel carrier 46 and gyro wheel 47 are mirror image and are set up in the both ends of mobile frame 45, so that mobile frame 45 moves more stable, and the inner wall fixed mounting of support 41 has slide rod 48, and the outer wall fixed mounting of mobile frame 45 has sliding sleeve 49, and sliding sleeve 49 slidingly installs in the outside of slide rod 48, in addition, slide rod 48 and sliding sleeve 49 are provided with two groups, and two groups of slide rod 48 and sliding sleeve 49 are mirror image and are set up in the both ends of mobile frame 45, so that mobile frame 45 moves more stable, and the top fixed mounting of mobile frame 45 has servo motor 410, and the output fixed mounting of servo motor 410 has rotating shaft 411, and the clamping of rotating shaft 411 has workpiece body 412.

[0031] When the embodiment is used, before the punching operation is performed on the conical workpiece body 412, each component is in an initial standby state. When it is ready to start punching, the asynchronous motor 42 on the support 41 is turned on, the output shaft of the asynchronous motor 42 drives the threaded rod 43 fixedly connected to the output shaft to start rotating. Since the threaded rod 43 is screwed with the threaded block 44, as the threaded rod 43 continues to rotate, the threaded block 44 moves axially on the threaded rod 43. Since the threaded block 44 is fixedly installed on the inner wall at the bottom end of the moving frame 45, the movement of the threaded block 44 drives the moving frame 45 to move laterally. During the lateral movement of the moving frame 45, the rollers 47 rotatingly installed inside the wheel frame 46 fixedly installed at the bottom of the moving frame 45 always roll against the inside of the support 41. Here, the two groups of mirror image wheel frames 46 and rollers 47 arranged at the two ends of the moving frame 45 are like the “stabilizing wheels” of the moving frame 45. During the movement, the rollers 47 are in rolling contact with the inside of the support 41, effectively sharing the weight of the moving frame 45 and reducing the friction during movement, while ensuring that the moving frame 45 does not deviate or shake during lateral movement. In addition, the sliding rod 48 fixedly installed on the inner wall of the support 41 cooperates with the sliding sleeve 49 fixedly installed on the outer wall of the moving frame 45. The sliding sleeve 49 smoothly slides outside the sliding rod 48, further constraining the movement direction of the moving frame 45, so that it can only move stably along the axial direction of the sliding rod 48, greatly improving the stability and precision of the movement of the moving frame 45. When the moving frame 45 moves to the target position, i.e., the edge of the workpiece body 412 is rotated to directly above the punching seat 3, the main punching head 2 on the machine body 1 is started. After the main punching head 2 is powered on, the power device inside the main punching head 2 drives the piston end to move downward rapidly to punch the edge of the workpiece body 412 located above the punching seat 3. After completing a punching operation, the piston end of the main punching head 2 retracts to the initial position. The servo motor 410 is started, and the output shaft of the servo motor 410 drives the rotating shaft 411 fixedly connected to the output shaft to start rotating. Since the workpiece body 412 is clamped on the rotating shaft 411, the rotation of the rotating shaft 411 can drive the workpiece body 412 to rotate synchronously. When the rotating shaft 411 rotates to the target position, the main punching head 2 is started again to perform downward punching operation. Such a cycle is repeated to realize punching on the entire edge of the conical workpiece body 412, thereby conveniently completing the punching operation on the entire conical workpiece body 412. Synchronously, the operator does not need to hold the workpiece body 412 for punching, which improves safety.

[0032] In an embodiment of the utility model, the machine body 1 top is provided with auxiliary assembly 5, auxiliary assembly 5 includes hydraulic cylinder 51, the machine body 1 inner wall fixed connection hydraulic cylinder 51 fixed end, hydraulic cylinder 51 piston end fixed connection push plate 52 one end, push plate 52 other end bottom fixed mounting is secondary punch head 53, punch seat 3 is set up through the through hole 54, in addition, the movement track of push plate 52 and main punch head 2 piston end two is not intersected, prevents the motion interference of two, in addition, the inside of the one end of support 41 close to main punch head 2 is provided with collection box 55, and the top opening of collection box 55 is located the just below of through hole 54, to better collection of the debris generated by punching.

[0033] When using the embodiment, before preparing to punch the workpiece body 412, first reset the main punch head 2, start the main punch head 2 in reverse, the power device in the main punch head 2 drives the piston end to overcome the force during punching, slowly retracts upwards until returns to the initial upper standby position, after the main punch head 2 resets, start the hydraulic cylinder 51 fixedly connected to the inner wall of the machine body 1, after the hydraulic cylinder 51 is electrified, the hydraulic oil in its interior pushes the piston end to extend under the action of pressure, since the piston end of the hydraulic cylinder 51 is fixedly connected with one end of the push plate 52, the extension of the piston end drives the push plate 52 to move horizontally, during the movement of the push plate 52, the secondary punch head 53 fixedly installed at the other end of the push plate 52 also moves synchronously, when the secondary punch head 53 moves to the position above the workpiece body 412 to be punched, start the secondary punch head 53, after the secondary punch head 53 is electrified, the power device in its interior drives the punch to move downwards quickly, and punches the workpiece body 412 located below the punch seat 3, during the punching process, the debris generated under the impact force of the punch and its own gravity separates from the punching position on the workpiece body 412 and falls downwards through the through hole 54 previously set up on the punch seat 3, since the top opening of the collection box 55 is located just below the through hole 54, the falling debris directly falls into the collection box 55, as the punching operation continues, the generated debris is continuously collected into the collection box 55, when the collection box 55 is full, take out the collection box 55 to clean the debris, after cleaning, put it back to its original position to continue the punching operation, thereby realizing the effective collection of the debris generated by punching, improving the practicability of the punch body during the punching operation, and keeping the working environment clean, thereby improving the work efficiency.
