[0002] Bearings are important components in mechanical equipment, mainly used to support rotating mechanical bodies and reduce moving friction. When manufacturing bearings, it is necessary to heat the bearing forgings and pre-punch through holes through stamping equipment to facilitate subsequent hole expansion operations. Since the bearing forgings after stamping fit with the stamping head, when the stamping head returns, it will cause the bearing forgings to adhere to the stamping head, resulting in the bearing forgings being taken away from the stamping table, affecting the clamping and transfer operations of workers or manipulators on the bearing forgings, and reducing the continuous stamping processing efficiency and the quality of bearing forgings. In view of the above technical problems, an anti-sticking stamping device for bearing forging is designed. Summary of the Utility Model

Specific implementation manner

[0027] To make the purpose, features and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the drawings in the specific embodiments of the present utility model.

[0028] Such as Figure 1 , Figure 2 , Figure 5 As shown, the present utility model provides a bearing forging anti-sticking stamping device, including a stamping machine frame 1, a lifting drive mechanism 2, a stamping head 3, and a stamping table 4. The lifting drive mechanism 2 adopts an existing hydraulic drive form, including a hydraulic cylinder and a mounting frame; the stamping head 3 is detachably connected to the drive end of the lifting drive mechanism 2 through the mounting frame, and the stamping head 3 moves up and down to complete the punching process of the bearing forging material; the device also includes a guiding vertical rod 5, a guiding cross rod 6, a clamping block 7, and a pressure rod 8; a blanking hole 41 is opened at the center of the stamping table 4; the guiding vertical rod 5 is slidably matched with the stamping table 4 along the up and down direction around the center of the blanking hole 41; a support spring 51 is connected between the top of the guiding vertical rod 5 and the stamping table 4; a push block 52 is arranged at the top of the guiding vertical rod 5;

[0029] Such as Figure 4 , Figure 7As shown in the figure, the inner side surface of the pushing block 52 is provided with a vertically smooth surface 521 and an inclined surface 522 that are smoothly transitioned from top to bottom; the inclined surface 522 is obliquely arranged from top to bottom in a direction away from the blanking hole 41; the middle part of the guiding cross bar 6 is slidably matched with the bracket 42 on the stamping table 4 along the horizontal direction; a return spring 61 is connected between the outer end of the guiding cross bar 6 and the bracket 42; the outer end of the guiding cross bar 6 contacts the vertically smooth surface 521 or the inclined surface 522, and the inner end of the guiding cross bar 6 is connected to the clamping block 7; under the elastic force of the supporting spring 51, the outer end of the guiding cross bar 6 is far away from the bracket 42 and finally abuts against the vertically smooth surface 521 or the inclined surface 522 of the pushing block 52.

[0030] It can be understood that when the guiding vertical bar 5 moves up and down, the vertically smooth surface 521 alternately abuts against the outer end of the guiding cross bar 6. Specifically, when the guiding vertical bar 5 is not stressed, the supporting spring 51 is relied on to stop the guiding vertical bar 5 at the highest position, and the return spring 61 is relied on to make the outer end of the guiding cross bar 6 abut against the inclined surface 522; when the guiding vertical bar 5 is pressed downwards, the inclined surface 522 pushes the outer end of the guiding cross bar 6 to compress the return spring 61, driving the clamping block 7 around the stamping table 4 to approach until the outer end of the guiding cross bar 6 abuts against the vertically smooth surface 521; when the force acting on the guiding vertical bar 5 is removed, the guiding vertical bar 5 and the guiding cross bar 6 are reset by the elastic return of the supporting spring 51 and the return spring 61.

[0031] During the stamping operation, the bearing forging is placed in the material position of the stamping table 4, and the approaching clamping blocks 7 play a role in circumferentially clamping and positioning the bearing forging.

[0032] As Figure 1 shown in the figure, the pressure bar 8 is connected to the stamping head 3, and the bottom end of the pressure bar 8 is vertically aligned with the top end of the guiding vertical bar 5; the stamping action of the stamping head 3 drives the pressure bar 8 to press down the guiding vertical bar 5.

[0033] The process of preventing sticking of materials during stamping of this device is as follows:

[0034] First, when the pressure bar 8 contacts the top end of the guiding vertical bar 5, there is an appropriate distance between the stamping head 3 and the top surface of the forging; then, when the pressure bar 8 presses down the guiding vertical bar 5 and moves down synchronously, the inclined surface 522 and the vertically smooth surface 521 of the pushing block 52 respectively push the outer end of the guiding cross bar 6, driving the clamping block 7 to approach the center of the blanking hole 41; when the clamping block 7 completely clamps the bearing forging, the stamping head 3 contacts the top surface of the forging; then, the stamping head 3 moves downwards to complete the stamping operation of the bearing blanking. At this time, the pressure bar 8 presses down the guiding vertical bar 5, and the outer end of the guiding cross bar 6 slides along the vertically smooth surface 521 of the pushing block 52, enabling the clamping block 7 to continuously position the bearing forging, as Figure 6 shown in the figure; preferably, in order to facilitate the centralized collection of the punched and dropped forgings, a material receiving box is provided below the blanking hole 41, and after processing, the waste materials are centrally transported.

[0035] Finally, during the upward reset movement of the stamping head 3 driven by the lifting drive mechanism 2, when the stamping head 3 disengages from the bearing forging, the outer end of the guiding cross bar 6 slides from the vertical surface 521 of the pushing and blocking block 52 to the inclined surface 522 of the pushing and blocking block 52, and the clamping block 7 releases the forging, effectively avoiding the situation of sticking materials during the stamping process.

[0036] Preferably, a baffle is provided at the junction of the top end of the guiding vertical bar and the bottom of the inclined surface; under the action of the supporting spring, the guiding vertical bar rises, and the baffle abuts against the outer end of the guiding cross bar to form a restraint, restricting the highest position of the guiding vertical bar.

[0037] Preferably, the supporting spring 51 is a slow-rebound air spring. When the stamping head 3 moves upward to disengage from the bearing forging, under the action of the supporting spring 51, the reset and rising action of the guiding vertical bar 5 lags behind for a certain time, ensuring the smooth and reliable separation of the stamping head 3 from the bearing forging.

[0038] Preferably, as Figure 3 shown, at least two groups of guiding vertical bars 5 are evenly arranged around the blanking hole 41; in this embodiment, four groups of guiding vertical bars 5 are provided; the guiding cross bar 6 and the clamping block 7 are correspondingly arranged; when the stamping head 3 descends for stamping, the four clamping blocks 7 approach and clamp the periphery of the bearing forging synchronously from four directions, playing a centering role; at the same time, when the stamping head 3 rises and resets, the clamping block 7 continuously clamps and restricts the position of the bearing forging, effectively avoiding the situation that the stamping head 3 sticks to the material and causes the forging to be misaligned.

[0039] As Figure 7 shown, a buffer pad 71 is provided on the clamping surface of the clamping block 7. The buffer pad 71 avoids the hard contact between the clamping block 7 and the forging, preventing the clamping impact from damaging the forging.

[0040] As Figure 2 shown, the pressure rod 8 includes a fixed rod 81 and an adjusting rod 82; the fixed rod 81 is connected to the stamping head 3, and the bottom of the adjusting rod 82 is vertically aligned with the top end of the guiding vertical bar 5; the top of the adjusting rod 82 is threadedly connected to the fixed rod 81 coaxially. Manually rotate the adjusting rod 82 to move the adjusting rod 82 away from or close to the top end of the guiding vertical bar 5 up and down, flexibly adjusting the distance between the adjusting rod 82 and the guiding vertical bar 5, so that the anti-sticking structure of the device can be used for bearing forgings of different thicknesses, ensuring that when the guiding vertical bar 5 descends or rises to a certain position, the clamping block 7 can reliably clamp or release the bearing forging, ensuring the reliable and accurate anti-sticking structure.

[0041] As Figure 7 shown, a roller 62 is installed at the outer end of the guiding cross bar 6. Relying on the rolling contact of the roller 62 with the inclined surface 522 and the vertical surface 521 of the pushing and blocking block 52, the resistance is reduced, the smoothness of the mechanism is improved, and the clamping action of the clamping block 7 is smooth and reliable.

[0042] As Figure 4As shown, an arc-transitioned groove 523 is formed on the vertical surface 521 of the pushing block 52, and the outer end of the guiding cross bar 6 slides in and out of the groove 523 along the vertical surface 521 of the pushing block 52. It can be understood that when the outer end of the guiding cross bar 6 slides into the groove 523, the plurality of clamping blocks 7 move outward to release the bearing forging. Therefore, the clamping blocks 7 can clamp the bearing forging twice to ensure accurate centering clamping. Preferably, at least two grooves 523 are arranged at intervals up and down along the vertical surface 521 of the pushing block 52.
