[0026] As a kind of technical optimization scheme of the utility model, the stamping machine body 1 is equipped with stamping structure 2, the top of the stamping machine body 1 is fixedly connected with hydraulic cylinder 201, the power of hydraulic cylinder 201 is opened, the telescopic end of hydraulic cylinder 201 is fixedly connected with sliding seat 202, four connecting pieces 204 are fixedly connected on sliding seat 202, four stand columns 205 are fixedly connected on the stamping machine body 1, connecting piece 204 and stand column 205 are slidably connected, not only guarantee the precision of movement, but also offset the lateral force generated in stamping process of sliding seat 202, the bottom of sliding seat 202 is fixedly connected with punch 203, the telescopic end of hydraulic cylinder 201 drives sliding seat 202 to move downward at this time, sliding seat 202 drives the punch 203 on the bottom to move downward at this time, finally, the bearing ring that stamping is completed is taken out from mould 6 by the clamp used by operator, and the production of bearing ring can be completed by subsequent operations such as circle expansion, polishing, polishing etc of the bearing ring after stamping, and production efficiency is high.

[0027] When using this invention, to change to a mold 6 of a different size, simply remove the initial mold 6 from the operating table of the stamping machine body 1, and then install the new mold 6. At this time, the two mounting plates 306 are in the open state. Place the new mold 6 in the center position of the stamping, and then pull out the pins 308 on the front and rear mounting plates 306 respectively. At this time, under the reset action of the first spring 307, the two mounting plates 306 slide along the slide rod 305 and the guide rod 302 towards the center position until the two clamping blocks 403 on the mounting plates 306 abut against the outer wall of the mold 6. Then, reinsert the two pins 308 into the corresponding ends of the two mounting plates 306, and make the bottom end of the pin 308 align with the corresponding insertion hole on the slide rod 305. When the two mounting plates 306 are interlocked, the initial adjustment of the distance between them is completed, resulting in high adjustment efficiency. Next, by rotating the screw 303 between the two mounting seats 301 using the handle 309, the screw 303, with its opposite threads at both ends, drives the two sliding sleeves 304 to move towards the center. The sliding sleeves 304 then move the sliding rod 305 and the mounting plate 306 towards the center. The two mounting plates 306 then drive the four clamping blocks 403 to clamp the mold 6, thus achieving further positioning and clamping of the mold 6. This prevents displacement of the mold 6 during stamping and allows for the fixing of molds 6 of different sizes, avoiding repeated bolt disassembly and improving installation efficiency. When it is necessary to adjust the mold according to the mold size... When adjusting the distance between the two clamping blocks 403 on the same mounting plate 306 to adjust the outer diameter of mold 6, simply rotate the first nuts 405 on the two connecting rods 401 respectively. When both first nuts 405 move towards both ends, the sliding plates 402 at the ends of the two clamping blocks 403 slide towards both ends under the reset action of the second spring 404. At this time, the distance between the two clamping blocks 403 is quickly adjusted, which is convenient for clamping and fixing molds 6 with different outer diameters. It is highly practical. Then, turn on the power of the hydraulic cylinder 201. At this time, the extension end of the hydraulic cylinder 201 drives the slide block 202 to move downward. Since the connecting parts 204 at the four corners of the slide block 202 slide between the four columns 205 respectively, the stability of the slide block 202 during the downward movement is ensured. This mechanism not only ensures the precision of movement but also counteracts the lateral force generated by the slide block 202 during the stamping process. At this time, the slide block 202 drives the punch 203 on its bottom surface to move downwards. First, the bottom end of the punch 203 passes through the center of the positioning plate 502. Then, the bottom end of the punch 203 contacts the top surface of the blank at the center of the mold 6. Simultaneously, the end of the punch 203 abuts against the upper surface of the positioning plate 502, causing the positioning plate 502 to slide downwards along the positioning post 501 until the bottom surface of the positioning plate 502 abuts against the blank, completing the stamping of the blank. Simultaneously, the punch 203 completes the punching operation on the blank. When the telescopic end of the hydraulic cylinder 201 retracts upwards, the positioning plate 502 slides back to its initial position under the reset action of the third spring 503.And the second nut 504 set at the top of the positioning column 501 can effectively avoid the positioning plate 502 from slipping, finally the operator uses the clamp to take out the bearing ring from the mold 6, and then the subsequent operations such as circle expanding, polishing and polishing on the punched bearing ring can complete the production of the bearing ring, and the production efficiency is high.
