Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a clamping and flipping device for forging parts processing. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and sizes. Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings made of the same material. During the bearing processing, it is necessary to forge parts to change their properties. During the forging process, the workpiece needs to be continuously flipped. Existing equipment is all flipped manually with pliers, which requires a large amount of manpower.

[0003] For example, the patent document with the publication number CN217595789U discloses a forging device for bearing processing, which is provided with a positioning mechanism that can support and position the bearing through the positioning mechanism to prevent the bearing from moving during forging and prevent the forging accuracy from decreasing. It is also provided with a reverse blanking mechanism that can automatically clamp and flip the bearing through the flipping blanking mechanism, thus facilitating the forging of both sides of the bearing and increasing the practicality of the device.

[0004] However, during the use of the above patent, when clamping the bearing with the clamping blocks, the two clamping blocks can only clamp both sides of the bearing, and the outer ring of the bearing is arc-shaped. Therefore, when flipping, the bearing will loosen or even fall off, affecting the processing progress. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a clamping and flipping device for forging parts processing to solve the above problems.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A clamping and flipping device for forging parts processing includes a base. A placing mechanism, a pressing mechanism, and a flipping mechanism are installed on the top of the base. The pressing mechanism is above the placing mechanism, and the flipping mechanism is behind the placing mechanism. A clamping mechanism is arranged on the front side of the flipping mechanism. The clamping mechanism includes two mounting plates. On one side of the mounting plates, two groups of limiting mechanisms are symmetrically installed. The limiting mechanism includes a rectangular plate fixedly connected to one side of the mounting plate. The bottom of the rectangular plate is fixedly connected with a mounting box. A spring is arranged in the mounting box. The bottom of the spring is provided with a connecting seat. The top of the connecting seat is slidably connected in the mounting box. The bottom of the connecting seat is fixedly connected with a clamping plate. One side of the clamping plate is fixedly connected with a guiding plate.

[0008] Preferably, the guide plate is an arc-shaped plate.

[0009] Preferably, the storage mechanism includes a carrier. The carrier is fixedly connected to the top of the base. An installation frame is fixedly connected to the top of the carrier. A lifting plate is slidably connected in the top plate of the installation frame. A hydraulic cylinder is fixedly connected to the top of the carrier. The output shaft of the hydraulic cylinder is fixedly connected to the lifting plate.

[0010] Preferably, the pressing mechanism includes a support frame. The support frame is fixedly connected to the top of the base. A first cylinder is fixedly connected to the bottom of the top plate of the support frame. A pressing block is fixedly connected to the output shaft of the first cylinder. A sliding groove is formed in the inner wall of the support frame. A sliding block is slidably connected in the sliding groove. One side of the sliding block is fixedly connected to the pressing block.

[0011] Preferably, the flipping mechanism includes a fixing plate. The fixing plate is fixedly connected to the top of the base. An electric push rod is fixedly connected to the front side of the fixing plate. A connecting plate is fixedly connected to the output shaft of the electric push rod.

Second cylinders are fixedly connected to both inner walls on both sides of the fixing frame. Two mounting plates are respectively fixedly connected to the output shafts of the two second cylinders.

[0013] The beneficial effects are as follows: When clamping the bearing, the guide plate will first contact the bearing. Thus, under the guidance of the guide plate, multiple clamping plates will clamp and fix the bearing. At the same time, when clamping and fixing, the clamping plate will squeeze the connecting seat, thereby driving the connecting seat to compress the spring. At the same time, the spring will generate a rebounding force, making the clamping of the bearing by the clamping plate more stable and preventing the bearing from loosening or falling during turning over.

The pressing mechanism is above the object placing mechanism, the flipping mechanism is behind the object placing mechanism, and a clamping mechanism for fixing is arranged on the front side of the flipping mechanism. The clamping mechanism includes two mounting plates 503, and two groups of limiting mechanisms for preventing the bearings from loosening are symmetrically installed on one side of the mounting plate 503.

[0025] The downward pressing mechanism includes a support frame 301, which is welded to the top of the base 1. A first cylinder 302 is bolted to the bottom of the top plate of the support frame 301. A pressing block 303 is threadedly connected to the output shaft of the first cylinder 302. A sliding groove 304 is formed in the inner wall of the support frame 301, and a slider 305 is slidably connected in the sliding groove 304. One side of the slider 305 is bolted to the pressing block 303. By the operation of the first cylinder 302, the pressing block 303 is driven to move up and down, thereby driving the slider 305 to slide in the sliding groove 304, and further making the movement of the pressing block 303 more stable. By the up and down movement of the pressing block 303, the bearing can be forged.

[0026] The placing mechanism includes a bearing frame 201, which is bolted to the top of the base 1. An installation frame 202 is bolted to the top of the bearing frame 201. A lifting plate 203 is slidably connected in the top plate of the installation frame 202. A hydraulic cylinder 204 is bolted to the top of the bearing frame 201. The output shaft of the hydraulic cylinder 204 is threadedly connected to the lifting plate 203. By the operation of the hydraulic cylinder 204, the lifting plate 203 is driven to move upward, thereby driving the bearing to move upward. The flipping mechanism includes a fixing plate 401, which is welded to the top of the base 1. An electric push rod 402 is bolted to the front side of the fixing plate 401. A connecting plate 403 is threadedly connected to the output shaft of the electric push rod 402. A motor 404 is bolted to the front side of the connecting plate 403. By the operation of the electric push rod 402, the connecting plate 403 is driven to move, thereby driving the motor 404 to move, and further driving the clamping mechanism to move around the bearing. The clamping mechanism includes a fixing frame 501, which is threadedly connected to the output shaft of the motor 404. Second cylinders 502 are bolted to the inner walls on both sides of the fixing frame 501. Two mounting plates 503 are respectively threadedly connected to the output shafts of the two second cylinders 502. By the operation of the two second cylinders 502, the mounting plates 503 are driven to move, thereby driving multiple groups of limiting mechanisms to clamp the bearing.

[0027] The limiting mechanism includes a rectangular plate 601, which is welded to one side of the mounting plate 503. A mounting box 602 is connected to the bottom of the rectangular plate 601 by screws. A spring 603 is arranged in the mounting box 602. A connecting seat 604 is arranged at the bottom of the spring 603. The top of the connecting seat 604 is slidably connected in the mounting box 602. A clamping plate 605 is connected to the bottom of the connecting seat 604 by bolts. A guide plate 606 is welded to one side of the clamping plate 605. The guide plate 606 is an arc-shaped plate. When clamping the bearing, the guide plate 606 will first contact the bearing. Thus, under the guidance of the guide plate 606, multiple clamping plates 605 will clamp and fix the bearing. At the same time, when clamping and fixing, the clamping plate 605 will squeeze the connecting seat 604, thereby driving the connecting seat 604 to compress the spring 603. At the same time, the spring 603 will generate a rebound force, making the clamping of the bearing by the clamping plate 605 more stable. Then, through the operation of the motor 404, the fixed frame 501 is driven to rotate, thereby driving the bearing clamped by multiple limiting mechanisms to flip, and thus realizing the turning over of the bearing.

[0028] Working principle: When in use, place the bearing to be forged on the top of the mounting frame 202. Then, through the operation of the first cylinder 302, drive the pressing block 303 to move up and down, thereby driving the slider 305 to slide in the sliding groove 304, and further making the movement of the pressing block 303 more stable. By moving the pressing block 303 up and down, the bearing can be forged. When turning over is needed, through the operation of the hydraulic cylinder 204, drive the lifting plate 203 to move up, thereby driving the bearing to move up. Then, through the operation of the electric push rod 402, drive the connecting plate 403 to move, thereby driving the motor 404 to move, and further driving the clamping mechanism to move around the bearing. Then, through the operation of two second cylinders 502, drive the mounting plate 503 to move, thereby driving multiple limiting mechanisms to clamp the bearing. When clamping the bearing, the guide plate 606 will first contact the bearing. Thus, under the guidance of the guide plate 606, multiple clamping plates 605 will clamp and fix the bearing. At the same time, when clamping and fixing, the clamping plate 605 will squeeze the connecting seat 604, thereby driving the connecting seat 604 to compress the spring 603. At the same time, the spring 603 will generate a rebound force, making the clamping of the bearing by the clamping plate 605 more stable. Then, through the operation of the motor 404, drive the fixed frame 501 to rotate, thereby driving the bearing clamped by multiple limiting mechanisms to flip, and thus realizing the turning over of the bearing. Then, through the operation of the electric push rod 402 and the second cylinder 502, place the bearing back on the mounting frame 202 for forging.
