Fig. 9As shown, one end of the socket 101 located in the slot 201 is fixedly embedded with a ball nut 104, and the ball nut 104 is threadedly connected to the screw rod 103, and the screw rod 103 is slidably plugged into the socket 101, one end of the screw rod 103 is rotatably connected to the rotary seat 200, and a flexible connecting rod 105 is fixedly connected in series between the screw rod 103 and the gear 306 shaft.

[0029] The present invention provides a stamping auxiliary device for producing medical equipment boxes, mainly providing a pneumatically controlled stamping structure, which consists of a punch 300, a rotary seat 200 and a socket 100, wherein the socket 100 is responsible for connecting with the piston rod of a hydraulic cylinder 400 that provides stamping force, and the rotary seat 200 and the socket 100 are telescopic, and the punch 300 can rotate relative to the beveled surface of the rotary seat 200. The stamping structure is connected to a solenoid valve and its negative pressure pipeline through a single air joint 107 to obtain a negative pressure source, and the size of the negative pressure is controlled by an electric throttle valve, and the screw rod 103 is located between the rotary seat 200 and the socket 100 and is sleeved with a spring three 106, and the elastic force of the spring one 308 is greater than that of the spring two 311.

[0030] The material picking, material discharging and head swinging actions of the stamping structure are all controlled by the strength of the negative pressure connected by the single air joint 107: refer to Figure 1 When the negative pressure obtained by the punching structure is a weaker level, the pressure difference between the inside and outside of the punch 300 is not enough to make the suction cup 302 compress the spring 1 308. At this time, the suction cup 302 protrudes from the punch 300 to better fit the surface of the workpiece, and the suction cup 302 contacts the workpiece to obtain an initial suction force to attract the workpiece. The hydraulic cylinder 400 acts to pull the punching structure and the workpiece away from the die 402. During the process, the small hole 1 315 and the small hole 2 316 are both in a sealed state. The pressure inside the suction cup 302 and the groove 301 is balanced through the through hole 310. At this time, the spring 2 311 does not act; refer to Figure 6 and Fig. 9 When the negative pressure obtained by the stamping structure increases to the stronger second level, not only the suction cup 302 adsorbs the workpiece more firmly, but also the rotary seat 200 overcomes the elastic force of the spring three 106, and the rotary seat 200 and the socket 100 contract, so that the screw rod 103 is inserted into the socket 101 and rotates under the action of the ball nut 104. The rotating screw rod 103 drives the gear 306 to rotate through the flexible connecting rod 105, and the gear 306 drives the punch 300 to rotate around the short shaft 303 through the tooth groove 305. When the socket 100 contacts the rotary seat 200 and the screw rod 103 stops rotating, the gear 306 drives the punch 300 to rotate 180 degrees, so that the punch 300 is deflected by 90 degrees horizontally and points vertically downward to the finished product collection frame (or conveyor belt, etc.); refer to Figure 3When the negative pressure obtained by the punching structure increases to the strongest level three, the pressure difference between the inside and outside of the punch 300 increases, so that the suction cup 302 overcomes the spring 1 308 and moves toward the groove 301, which makes the baffle 317 no longer close the small hole 2 316, and the small hole 1 315 moves out of the inner wall of the adapter cup 307. The small holes 1 315 and the small holes 2 316 are connected to the outside of the punch 300, and the air bypasses the suction cup 302 and enters the suction cup 302. A strong airflow passes through the through hole 310 of the short tube 309, driving the short tube 309 to compress the spring 2 311 and finally close the suction cup 302, so that the suction force of the suction cup 302 becomes weak or disappears, and the workpiece separates from the punch 300 and falls into the finished product collection frame (or conveyor belt, etc.); If the negative pressure is downgraded to level one or the solenoid valve is directly controlled to control the gas connector 107 to be directly connected to the atmosphere, the stamping structure is reset under the push of spring 1 308 , spring 2 311 and spring 3 106 .

[0031] To achieve the above functions, the gas path of the stamping structure is: Figure 5 The air connector 107 sequentially connects the air hole 2 102 , the slot 201 , the air hole 1 202 , the annular groove 304 , the opening between the annular groove 304 and the groove 301 , the groove 301 , the short tube 309 , the suction cup 302 , and the adapter cup 307 .

[0032] A spiral groove 312 is provided on the peripheral wall of the short shaft 303 of the stamping structure, and an oil suction ring 313 is sleeved between the outer wall of the short shaft 303 and the rotary seat 200. When the punch 300 swings, the short shaft 303 rotates and the spiral groove 312 thereon will scrape grease from the oil suction ring 313, and the grease is evenly coated between the short shaft 303 and the rotary seat 200 under the pushing and coating effect of the spiral groove 312, thereby playing a lasting lubricating role.

[0033] This stamping structure is suitable for light-load processing of medical thin-walled aluminum alloy round box containers, but is not suitable for large-tonnage stamping and stretching processing. However, the stamping structure of the present invention has strong compatibility and is also suitable for use in spinning equipment to replace spinning solid cylindrical blocks.

[0034] In summary, the strength of the negative pressure connected by the single air joint 107 of the stamping structure can not only realize the original stamping and stretching functions of the punch 300, but also realize the material picking, material discharge and head swinging actions of the punch 300. It can replace the servo manipulator with a simple and reliable pneumatic mechanical structure, and automatically grasp and transfer objects after stamping, thereby realizing the cost reduction and efficiency improvement of the automated stamping and stretching production line.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
