Description

Technical Field

[0001] This utility model belongs to the field of spring processing technology, and specifically relates to a stamping device for spring processing. Background Technology

[0002] Stamping utilizes dies on a press to form various sheet metal parts, shells, containers, or tubular components into various tubular parts. This type of forming process, performed in a cold state, is called cold stamping, or simply stamping. Stamping is a manufacturing technology that uses the power of conventional or specialized stamping equipment to directly subject sheet metal to deformation forces within a die, thereby obtaining product parts with specific shapes, dimensions, and properties.

[0003] In existing related technologies, the stamping head moves up and down to stamp the spring. However, the waste generated during stamping cannot be effectively discharged, which greatly reduces the stamping efficiency of the spring. Therefore, it is urgent to design a stamping device for spring processing to solve these problems. Utility Model Content

A receiving box 212 is installed at the lower end of the base platform 1, and a pusher plate 213 is longitudinally movably installed inside the receiving box 212. An installation and fixing assembly is provided at the lower end of the base platform 1. A first mounting platform 2052 is provided above the support platform 205, and a nitrogen spring 2051 is provided between the support platform 205 and the first mounting platform 2052. The installation and fixing assembly includes a support column 201 located at the lower end of the base platform 1, and fixing bolts 202 are installed on the support column 201. An anti-slip platform 2081 is provided on the clamping platform 208, and an explosion-proof light 211 is provided above the upright plate 203. An electro-hydraulic telescopic rod is installed on the pusher plate 213. The anti-slip platform 2081 is made of soft anti-slip material.

[0026] In this embodiment: the stamping actuator 3 includes support platforms 301 fixedly mounted on both sides above the base platform 1. A guide column 302 is vertically mounted on the support platform 301, and a top plate 304 is fixedly mounted on the guide column 302. A return hydraulic cylinder 303 is mounted on the base platform 1. A first lifting platform 305 is provided at the telescopic end of the return hydraulic cylinder 303. A buffer assembly is mounted on the top plate 304, and a clearance hole 308 is vertically provided on the top plate 304. A lifting hydraulic cylinder 309 is installed through the top of the first lifting platform 305. The lifting hydraulic cylinder 309 is a multi-stage telescopic rod. A second lifting platform 310 is provided at the telescopic end of the lifting hydraulic cylinder 309, and a stamping assembly is provided at the lower end of the second lifting platform 310. The buffer assembly includes a buffer plate 307 mounted on the top plate 304, and a first damping spring 306 is provided between the buffer plate 307 and the top plate 304. The stamping assembly includes a second mounting platform 312 located at the lower end of the second lifting platform 310, on which a stamping head 313 is mounted. Auxiliary telescopic rods 3091 are vertically parallel on both sides of the lifting hydraulic cylinder 309. A second damping spring 311 is provided between the second lifting platform 310 and the second mounting platform 312. The second damping spring 311 serves to buffer the stamping action of the stamping head 313. The return hydraulic cylinder 303 is used to execute the return stroke of the first lifting platform 305.

[0027] Working principle: In use, the spring to be stamped is first placed on the support platform 205. The electric telescopic cylinder 207 is activated, which drives the clamping platform 208 and the anti-slip platform 2081 to move relative to each other, fixing and clamping the spring to be stamped. The return hydraulic cylinder 303 is activated, which drives the first lifting platform 305, the lifting hydraulic cylinder 309, and the stamping head 313 to move down. When the stamping head 313 moves down to the outer surface of the spring to be stamped, the lifting hydraulic cylinder 309 is activated to push the second lifting platform 310, the second mounting platform 312, and the stamping head 313 to stamp the stamping surface of the spring to be stamped. The nitrogen spring 2051 provides cushioning. During the stamping process, the explosion-proof lamp 211 can provide illumination. At the same time, the air pump in the air box 209 is started to blow away the waste generated by stamping through the exhaust pipe. The waste generated by stamping falls into the receiving box 212 through the material leakage hole 210. When the waste accumulates to a certain amount, the electric hydraulic telescopic rod is started to push the pusher plate 213 to push the waste out of the receiving box 212. After a batch of springs is stamped, the return hydraulic cylinder 303 is started to push the first lifting platform 305 to rise, creating a certain distance from the stamping springs. When stamping a new batch of springs, the height of the first lifting platform 305 is adjusted so that the height of the stamping head 313 is adapted to the height of the new batch of springs, so that the stamping head 313 can be better driven by the lifting hydraulic cylinder 309 to perform stamping.
