Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6 , a cylinder telescopic positioning mechanism provided by the present invention includes an operating table 1, and further includes a positioning component arranged on the operating table 1 for positioning the workpiece to be punched and a separation component for separating the waste after punching and positioning. Above the operating table 1, there is a punch 6 for punching the workpiece, and the workpiece is located between the punch 6 and the operating table 1 after positioning. An elevating component for lifting and lowering the punch 6 is arranged on the operating table 1;

[0023] The positioning component includes a positioning connection block 201 arranged above the operating table 1. Below the operating table 1, there is a cylinder 202 for driving the lifting of the positioning connection block 201. The upper end of the positioning connection block 201 is fixed with a positioning rod 203. The upper end of the positioning rod 203 is fixed with a pin 204. The front end of the pin 204 is tapered. A jack 205 for inserting and positioning with the pin 204 is opened on the workpiece. A support component for supporting the workpiece to be stripped after positioning is arranged on the positioning rod 203;

[0024] It should be noted here that: during the process of punching the workpiece, through the mutual cooperation of the positioning component, the separation component and the support component, not only can the workpiece to be punched be positioned, facilitating more accurate punching operation of the workpiece, but also the remaining material of the workpiece can be effectively separated and stripped after punching, improving the practicability during the punching and positioning process.

[0025] Two groups of positioning components are symmetrically arranged on the operating table 1;

[0026] It should be noted here that: through the two groups of positioning components, the positioning effect and stability are ensured.

[0027] The support assembly includes a mounting ring 301 fixed to the outside of the positioning rod 203. A support ring 302 is sleeved on the outside of the pin 204. A plurality of elastic components for elastic connection are arranged between the support ring 302 and the mounting ring 301;

[0028] It should be noted here that: during the process of positioning and placing the workpiece through the interaction between the pin 204 and the jack 205, the lower end of the workpiece abuts against the support ring 302, pushing the support ring 302 to move towards the mounting ring 301. During the movement, each group of first sliding rods 402 are respectively pushed to slide on each group of first sleeves 401 and the spring 403 is deformed by force to generate elastic force. Through the elastic force of the spring 403, the support ring 302 is pushed to keep abutting against the bottom of the workpiece to support the workpiece, facilitating more stable stamping operation. And after stamping, through the abutting and pushing action between the support ring 302 and the bottom of the workpiece residue, it is convenient to assist the subsequent separation and blanking operation of the workpiece residue.

[0029] The elastic component includes a first sleeve 401 fixed to the mounting ring 301. A first sliding rod 402 is slidably connected to the first sleeve 401. One end of the first sliding rod 402 is fixed to the support ring 302. A spring 403 is sleeved on the outside of the first sleeve 401. The two ends of the spring 403 are respectively abutted against the mounting ring 301 and the support ring 302;

[0030] It should be noted here that: through the first sleeve 401 and the first sliding rod 402, it is convenient for the sliding guidance of the support ring 302 after being stressed. Through the spring 403, it is convenient to elastically push the contracted support ring 302.

[0031] The separation component includes an inclined material guide plate 501. The material guide plate 501 is located between the positioned workpiece and the operating table 1. The material guide plate 501 and the operating table 1 are fixedly installed through a plurality of mounting rods 502. An avoidance groove 503 for avoiding the positioning connection block 201, the positioning rod 203 and the pin 204 is formed on the material guide plate 501;

[0032] It should be noted here that: after positioning the workpiece, through the lifting component, the punch 6 is driven to descend and abut against the workpiece to complete the stamping operation of the workpiece. After stamping, the material of the workpiece remains at the front end of the positioning rod 203 through the interaction between the pin 204 and the jack 205. At this time, through the air cylinder 202, the positioning connection block 201 and the positioning rod 203 are driven to descend. During the descending movement of the positioning rod 203, through the interaction between the pin 204 and the jack 205, the workpiece residue is driven to descend. During the descending movement of the workpiece residue, the workpiece residue abuts against the upper end of the material guide plate 501. Through the abutting action of the material guide plate 501 on the workpiece residue, the pin 204 is separated and slides out from the jack 205. At this time, the inclined material guide plate 501 separates and conveys the workpiece residue.

[0033] The lifting assembly includes a U-shaped frame 701 fixed to the upper end of the operating table 1. A threaded tube 702 is rotatably connected to the U-shaped frame 701. A threaded rod 703 is in threaded engagement with the threaded tube 702. One end of the threaded rod 703 is fixed to the upper end of the punch 6. A drive motor 704 for driving the threaded tube 702 is installed on the U-shaped frame 701. Two groups of second sleeves 705 are fixed to the U-shaped frame 701. The two groups of second sleeves 705 are symmetrically arranged on both sides of the threaded tube 702. A second sliding rod 706 is slidably connected to the second sleeve 705. One end of the second sliding rod 706 is fixed to the punch 6;

[0034] It should be noted here that: by the drive motor 704, the threaded tube 702 is driven to rotate. During the rotation of the threaded tube 702, through the meshing transmission between the threaded tube 702 and the threaded rod 703 and the sliding guiding action of the second sleeve 705 and the second sliding rod 706, the punch 6 performs a lifting motion.

[0035] Working principle: During the process of stamping a workpiece, the workpiece is pushed towards the positioning rod 203 and abuts against the end of the positioning rod 203. During the pushing process, the pin 204 is inserted into the jack 205. Through the action of the pin 204 and the jack 205 and the action of the workpiece abutting against the end of the positioning rod 203, the workpiece to be stamped is positioned, facilitating more accurate stamping operation of the workpiece;

[0036] After the workpiece is positioned, through the lifting assembly, the punch 6 is driven to descend and abut against the workpiece, completing the stamping operation of the workpiece. After stamping, the material of the workpiece remains at the front end of the positioning rod 203 through the interaction between the pin 204 and the jack 205. At this time, through the air cylinder 202, the positioning connection block 201 and the positioning rod 203 are driven to descend. During the descending movement of the positioning rod 203, through the interaction between the pin 204 and the jack 205, the workpiece residue is driven to descend. During the descending movement of the workpiece residue, the workpiece residue abuts against the upper end of the material guiding plate 501. Through the abutting action of the material guiding plate 501 on the workpiece residue, the pin 204 is separated and slides out of the jack 205. At this time, the inclined material guiding plate 501 separates and conveys the workpiece residue, realizing the separation and blanking of the workpiece residue after stamping, and improving the practicability during the stamping positioning process;

[0037] During the process of positioning and placing the workpiece through the interaction between the bolt 204 and the socket 205, the lower end of the workpiece abuts against the support ring 302, pushing the support ring 302 to move towards the mounting ring 301. During the movement, each group of first slide rods 402 are respectively pushed to slide on each group of first sleeves 401 and the spring 403 is deformed under force to generate elastic force. Through the elastic force of the spring 403, the support ring 302 is pushed to keep abutting against the bottom of the workpiece to support the workpiece, facilitating a more stable stamping operation. And after the stamping is completed, through the abutting and pushing action between the support ring 302 and the bottom of the workpiece residue, it is convenient to assist in the subsequent separation and blanking operation of the workpiece residue.
