PREFERRED EMBODIMENT

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figs. 1 to 4 As shown, a punching device for processing thin-walled annular hardware parts includes a support platform 1, a support leg 2 fixedly connected to the bottom end of the support platform 1, a support disassembly and assembly mechanism 31 provided on the support platform 1, and a punching mechanism 32 provided above the support disassembly and assembly mechanism 31. The support disassembly and assembly mechanism 31 includes a support plate 311 fixedly connected to the top end of the support platform 1. An installation groove is opened on the outer wall of one side of the top end of the support plate 311. A motor 312 is fixedly installed on the inner wall of the installation groove. A support shaft 313 is fixedly connected to the output end of the motor 312. A sliding sleeve 314 is fixedly connected to the outer wall of the support shaft 313. The inner wall of the sliding sleeve 314... A spring 315 is fixedly connected to the bottom end. A positioning slide rod 316 is fixedly connected to the end of the spring 315 away from the inner wall of the sliding sleeve 314. A support template 317 is snapped onto the outer wall of the positioning slide rod 316. A positioning hole 318 is opened on the inner wall of the support template 317. The outer wall of the positioning slide rod 316 is snapped onto the inner wall of the positioning hole 318. A stamping die hole 319 is opened on the outer wall of the support template 317. An annular piece 3110 is fitted on the outer wall of the support template 317. A connecting plate 3111 is fixedly connected to the outer wall of the positioning slide rod 316. A pull plate 3112 is fixedly connected to the end of the connecting plate 3111 away from the positioning slide rod 316.

[0027] Furthermore, there are three positioning slide rods 316 and positioning holes 318. The positioning slide rods 316 and positioning holes 318 are evenly and equidistantly distributed on the support shaft 313 and the support template 317. The positioning slide rods 316 at the three locations can evenly support the inner wall of the support template 317 to improve the stability during the processing.

[0028] Furthermore, the outer wall of the positioning slide rod 316 is fitted with the inner wall of the positioning hole 318, and the outer wall of the positioning slide rod 316 is fitted with the inner wall of the sliding sleeve 314. This ensures the support stability after installation and also ensures stability during rotational processing.

[0029] Furthermore, the outer wall of the support template 317 is provided with a rubber layer, and the pull plate 3112 is arc-shaped. The rubber layer can increase the frictional tightness between the support template 317 and the annular part 3110, thus ensuring its stability.

[0030] The punching mechanism 32 comprises a support frame 321 fixedly connected at the top end of the support plate 311, the inner wall bottom end of the support frame 321 is fixedly connected with a hydraulic cylinder 322, the output end of the hydraulic cylinder 322 is fixedly connected with a support block 323, the end away from the hydraulic cylinder 322 of the support block 323 is rotatably connected with a rotating roller 324, and the outer wall of the rotating roller 324 is fixedly connected with a punching head 325.

[0031] Further, the punching head 325 is several in number, and the punching head 325 is uniformly and equidistantly distributed on the outer wall of the rotating roller 324, so that it can follow the rotation and uniformly punch the outer wall of the annular part 3110.

[0032] Further, the outer wall of the punching head 325 is matched with the inner wall of the punching die hole 319, so that the punching head 325 can cooperate with the punching die hole 319, and then complete the punching operation by rotating.

[0033] The implementation principle of the punching device for thin-walled annular hardware part machining in the embodiment is as follows: first, according to the size of the annular part 3110 to be punched, the corresponding support template 317 is installed. During the installation process, first, the pull plate 3112 is pushed down, so that the pull plate 3112 drives the connecting plate 3111 to move downward, and with the movement of the connecting plate 3111, the positioning slide rod 316 is moved downward, and at the same time, the spring 315 is extruded during the movement of the positioning slide rod 316. Then, the pull plate 3112 on the left side or the right side is pushed to make the outer wall of the positioning slide rod 316 on the left side or the right side disengage from the inner wall of the positioning hole 318. At this time, the two pull plates 3112 will be close to each other. Then the worker directly holds the two pull plates 3112 on both sides, and then pulls the pull plate 3112 at the third position again, so that the pull plate 3112 at the third position is close to the two pull plates 3112 held by the worker to form a cylindrical shape. The worker can hold the three pull plates 3112 forming a cylinder, and then the worker can set the support template 317 corresponding to the annular part 3110 on the three positioning slide rods 316. Then the worker releases the pull plate 3112. At this time, the spring 315 will be reset to push the positioning slide rod 316 to reset, so that the outer wall of the positioning slide rod 316 is clamped in the positioning hole 318 in the inner wall of the support template 317. In this way, the installation of the support template 317 is completed. After the installation is completed, the annular part 3110 is set on the outer wall of the support template 317. In this way, the support template 317 can support the annular part 3110, preventing uneven stress from causing the annular part 3110 to deform during punching, thereby causing the workpiece to be scrapped. When punching, the motor 312 is started, and the output end thereof drives the support shaft 313 to rotate, and then drives the three positioning slide rods 316 to rotate, so that the support template 317 is driven to rotate, and the punching mechanism 32 is driven to complete the punching.

[0034] After the ring member 3110 is sleeved, the hydraulic cylinder 322 is started, and the output end will drive the support block 323 to move downward. With the movement of the support block 323, the rotating roller 324 is driven to move downward. At this time, the rotating roller 324 will drive the stamping head 325 to extrude on the outer surface of the ring member 3110. Then, the first stamping can be completed by cooperating with the stamping die hole 319 on the corresponding support template 317. Then, the rotation of the support template 317 can drive the rotating roller 324 to rotate. With the rotation of the support template 317 for one turn, the stamping operation of the ring member 3110 can be completed. In this way, the stamping action can be completed at one time, and the ring member 3110 does not need to be adjusted during the process, which is convenient to use.
