The lower end of the hydraulic cylinder A 330 is connected to the stamping die frame 320 for stamping and shaping workpieces. The shearing structure 4 is located on the side of the shaping and stamping structure 3 away from the sorting and feeding structure 2. The shearing structure 4 includes a shearing seat 420. The height of the shearing seat 420 is the same as the feeding height of the stamping die frame 320. The shearing seat 420 is used to cut off workpieces. The installation table 1 is a steel frame structure and is provided with fixed seats at the lower end for connection to the ground. When in use, other process processing equipment can be connected to the side of the shearing structure 4 away from the sorting and feeding structure 2.

[0031] The shearing structure 4 further includes a mounting bracket B410. The lower end of the mounting bracket B410 is provided with bolts for fixed connection with the mounting table 1. The upper end of the mounting bracket B410 is fixed with a hydraulic cylinder B430.

A hydraulic control valve 431 is arranged on one side of the hydraulic cylinder B430. One end of the hydraulic control valve 431 is provided with hydraulic pipelines respectively connected with the hydraulic cylinder A330 and the hydraulic cylinder B430. The stamping die holder 320 includes an upper sizing die 321 and a mounting block 322.

A counting module can be installed inside the shearing structure 4. The counting module can monitor the working state of the hydraulic cylinder B430, so as to reflect the specific number of processed workpieces, which is convenient for statistics and management.

[0032] When in use, after the strip raw material is introduced into the feeding structure 220 through the guide groove 210, the strip extends out of the feeding wheel. Subsequently, a part of the strip is completely placed between the stamping die holders 320 inside the sizing and stamping structure 3. Then, the device is started through the control panel 412. At this time, the hydraulic control valve 431 supplies oil to the hydraulic cylinder A330, and the upper sizing die 321 moves downward along the guiding seat 331. Subsequently, the upper sizing die 321 fits with the lower die and stamps the strip. Then, the hydraulic control valve 431 controls the oil supply circuit to lift the upper sizing die 321 by the hydraulic cylinder A330. At this time, the motor 231 runs and drives the feeding wheel 221 through the speed reducer 230 to move the stamped strip to the shearing structure 4. Subsequently, the hydraulic control valve 431 controls the operation of the hydraulic cylinder B430 to cut and size the processed part of the strip; during this process, the other end of the strip moves to the position of the sizing and stamping structure 3 for stamping processing, thus realizing the high-efficiency operation of the whole set of processing.

[0033] When in use, as the strip is fed, its diameter will always change, which easily causes a certain deviation of the strip raw material during the feeding process, thus affecting the overall processing. Therefore, the following improvements are made to limit the feeding state of the strip:

[0034] As Figure 3 shown in the figure Figure 4 As shown, the lower end of the material guiding groove 210 is fixedly connected to the mounting table 1 through a square steel bracket 211. The inner side of the square steel bracket 211 is provided with a square through hole. A lead screw 212 is arranged inside the through hole. Both ends of the lead screw 212 are provided with rotating seats and are rotatably connected to the square steel bracket 211.

The upper end of the sliding connection block 213 extends out of the slot and is connected to a right-angle plate, which is used for moving and limiting the arrangement of strip steel with different widths. A sliding plate 214 is fixed to the upper end of the square steel bracket 211. A chute is provided at a position near the right-angle plate on the upper end of the sliding plate 214. The chute is located on both sides of the lead screw 212. A limiting protrusion is provided at the lower end of the right-angle plate and is slidably connected with the chute in a matching manner. A rotating wheel 215 is provided on one of the right-angle plates. One end of the rotating wheel 215 is provided with a rotating shaft and is connected to the right-angle plate. A through hole is provided at a position on the other right-angle plate close to the rotating wheel 215. The diameter of the through hole is lower than the diameter of the rotating wheel 215, which is used to facilitate the extension of the rotating wheel 215 to one side of the right-angle plate through the through hole. The rotating wheel 215 is used to limit the feeding direction of the strip steel. A connecting rubber pad can be sleeved on the outer side of the rotating wheel 215 to prevent the rotating wheel 215 from damaging the strip steel raw material during rotation.

[0035] When in use, the operator can rotate the lead screw 212 through the rotating handle 216 according to the size of the strip steel. At this time, the lead screw 212 will drive the sliding connection block 213 to move and change the width of the material guiding groove 210 so as to adapt to the fibers of strip steel raw materials with different widths. When feeding, the rotating wheel 215 will press down on the strip steel to prevent the strip steel from shifting.

[0036] As Figure 1 shown in the figure Figure 5As shown, the feeding structure 220 further includes a supporting wheel 222. The supporting wheel 222 is located below the feeding wheel 221. The inner side of the supporting wheel 222 is provided with a rotating shaft and a fixing block, which are fixedly connected to the mounting table 1. One side of the feeding structure 220 is provided with an orientation structure 240. The orientation structure 240 is located between the feeding structure 220 and the mounting frame A 310. The orientation structure 240 includes a pulley and a height limiting plate 241. The height limiting plate 241 is fixedly connected to the mounting table 1 through a support rod. The height of the height limiting plate 241 is lower than that of the supporting wheel 222. The pulley is used to flatten the strip steel. Spring rods A 242 are symmetrically arranged on both sides of the pulley. The spring rods A 242 are inclined at 15°. A connecting block is fixed between the spring rods A 242. The inner side of the connecting block is provided with a rotating shaft, which is slidably connected to the pulley. A sliding block is fixed on the side of the spring rod A 242 away from the pulley. The inner side of the support rod is provided with a slot. The sliding block is slidably connected to the slot. A spring rod B 243 is provided on the side of the support rod away from the pulley. The lower end of the spring rod B 243 is fixedly connected to the sliding block. A handle 244 is fixed to the upper end of the sliding block. The spring rods A 242 and the spring rod B 243 are used to push the pulley downward to ensure the normal feeding of the strip steel. Rubber rings are provided on the outer sides of the feeding wheel 221 and the supporting wheel 222. Anti-slip patterns are provided on the outer sides of the rubber rings. A screw rod is provided at the upper end of the feeding wheel 221. The screw rod is rotatably connected to an external support frame. The feeding wheel 221 can adjust the feeding operation height.

[0037] When in use, the feeding wheel 221 and the supporting wheel 222 will clamp the strip steel and feed it to the shaping and stamping structure 3. When passing through the orientation structure 240, the pulley and the height limiting plate 241 will stabilize the height of the strip steel again and feed it into the stamping die holder 320. During the use process, the operator can lift the height of the pulley through the handle 244, so as to facilitate the adjustment of the strip steel at the upper end of the height limiting plate 241.
