Description

TECHNICAL FIELD

[0001] The present application relates to the field of forging equipment, and in particular to a full-automatic overturning forging workbench. BACKGROUND

[0002] Forging is a processing method that makes metal materials produce plastic deformation by applying external force to obtain the required shape, size and performance. It is an important part of metal plastic processing and is widely used in mechanical manufacturing, automobile, aerospace, military and other fields. In the existing hot forging production technology process, after the blank is heated in the heating furnace, it is taken out from the heating furnace by manual or personnel operation of auxiliary mechanical equipment, and placed on the turntable of the forging equipment. The operator operates the forging equipment to make the forging hammer hit the blank to make it produce plastic deformation. In the process of hammering, the blank is continuously turned and shaped by manual or personnel operation of auxiliary mechanical equipment, and the blank obtains the required shape and size under the cooperation of the hammering process.

[0003] In the forging process, when the blank or the forged piece is overturned, the blank or the forged piece needs to be clamped by the clamping part and lifted to a certain height for overturning to avoid interference between the blank or the forged piece and the workbench during overturning. The conventional overturning mechanism is to drive the clamping part to rotate relative to the clamping arm or the clamping arm to rotate to realize the overturning of the blank or the forged piece. However, the motor-driven rotation cannot accurately control the angle of rotation of the clamping arm or the clamping part, so the overturning angle cannot be accurately controlled. SUMMARY

[0032] In the embodiment of the present application, during the forging process of the forging mechanism, the lifting clamping driving part 500 works and drives the two clamping parts 400 to move close to each other, so that the two clamping units 420 move close to the center of the forging table 100 synchronously, and the forging piece is clamped by the two clamping units 420 from the opposite symmetrical side walls; the lifting cylinder 800 works and lifts the lifting clamping driving part 500, the lifting clamping driving part 500 drives the clamping part 400 and the forging piece, and the turnover pull rod 600 moves upward along the turnover guide part synchronously with the lifting clamping driving part 500; when the turnover pull rod 600 moves to the highest position, the turnover guide part acts on the turnover pull rod 600 to make the turnover pull rod 600 move horizontally away from the lifting clamping driving part 500, the turnover action rod unit 430 moves with the turnover pull rod 600 and acts on the corresponding clamping unit 420, the turnover action rod unit 430 drives the clamping unit 420 to rotate, and the clamping unit 420 drives the forging piece to overturn, thereby realizing automatic overturning of the forging piece; since the forging piece is lifted, the end part of the forging piece does not interfere with the upper end surface of the rotary disc part 110 and the forging table 100 during overturning; the distance that the turnover pull rod 600 moves under the action of the turnover guide part is adjusted, so that the distance that the turnover action rod unit 430 moves in the clamping hollow arm 410 is adjusted, and then the overturning angle of the clamping unit 420 is adjusted to adapt to the requirement of the forging on the overturning angle of the forging piece; after the forging piece is overturned, the lifting cylinder 800 drives the lifting clamping driving part 500 to move downward, the turnover pull rod 600 moves vertically downward along the turnover guide part, and at the same time, the clamping part 400 and the forging piece move downward with the lifting clamping driving part 500; when the turnover pull rod 600 moves to the bottom end position of the turnover guide part, the turnover pull rod 600 moves to the lifting clamping driving part 500 in an inclined downward manner to facilitate returning to the initial position; before the turnover pull rod 600 moves to the bottom end position of the turnover guide part, the bottom of the forging piece contacts the upper surface of the rotary disc part 110, and the lifting clamping driving part 500 drives the two clamping parts 400 to move away from each other and automatically releases the forging piece, so as to facilitate the forging mechanism to perform the forging work.

[0033] In one embodiment, as Figures 1-5As shown, the end of the turnover action rod unit 430 away from the end of the lifting and clamping driving component 500 is connected with the end of the clamping action unit 420 through the turnover spring 900, and the turnover spring 900 is always in a stretched state. The turnover guide part includes a guide groove part provided on the surface of the guide side plate 200 and a downward positioning guide plate 260. The guide groove part includes an upward guide groove 210, an upper horizontal guide groove 240, a downward inclined return groove 280, and a plurality of downward guide grooves 220. The upward guide groove 210 is located on the side of the guide side plate 200 close to the lifting and clamping driving component 500, and the plurality of downward guide grooves 220 are located on the side of the upward guide groove 210 away from the lifting and clamping driving component 500 and are distributed at equal intervals. Adjacent two downward guide grooves 220 and the upward guide groove 210 and the downward guide groove 220 form a limiting guide part 230. The upward guide groove 210 and the downward guide groove 220 are connected and communicated at the top through the upper horizontal guide groove 240 and are connected and communicated at the bottom through the downward inclined return groove 280. The end of the turnover pull rod 600 extends into the guide groove part and moves inside it. The downward positioning guide plate 260 is slidably arranged inside the upper horizontal guide groove 240 and is connected with an adjuster 270 provided on the top of the guide side plate 200. The adjuster 270 is used to adjust the position of the downward positioning guide plate 260 on the upper horizontal guide groove 240. In the embodiment of the present application, in the initial state, the end of the turnover pull rod 600 is located at the bottom of the upward guide groove 210. When the lifting cylinder 800 drives the lifting and clamping driving component 500 to move upward, the turnover pull rod 600 moves upward with the lifting and clamping driving component 500, and the end of the turnover pull rod 600 moves upward inside the upward guide groove 210. When the turnover pull rod 600 moves to the inside of the upper horizontal guide groove 240, the lifting cylinder 800 stops moving. Under the pushing of the turnover spring 900, the turnover action rod unit 430 moves inside the clamping action unit 420. The turnover action rod unit 430 acts on the clamping action unit 420 and makes it rotate. The clamping action unit 420 drives the clamped forging to overturn. The moving turnover action rod unit 430 pushes the turnover pull rod 600 to move, and the end of the turnover pull rod 600 moves inside the upper horizontal guide groove 240 in a direction away from the upward guide groove 210 until the end of the turnover pull rod 600 abuts against the downward positioning guide plate 260. At this time, the forging has been overturned by a certain angle, and the turnover pull rod 600 is located at the top of one of the downward guide grooves 220. The lifting cylinder 800 works and drives the lifting and clamping driving component 500 to move downward. The turnover pull rod 600 moves downward along one of the downward guide grooves 220 while following the lifting and clamping driving component 500. Due to the blockage of the limiting guide part 230, the turnover pull rod 600 and the turnover action rod unit 430 stably move downward, and the forging moves downward in the overturned state.When the turnover pull rod piece 600 moves to the bottom of the lower moving guide groove 220, the lifting clamping driving part 500 drives the two clamping parts 400 to move away, and then the clamping action unit 420 releases the forging piece; the forging piece is in the state of turnover on the rotating disc part 110, which is convenient for subsequent forging operation; after the turnover pull rod piece 600 moves to the inside of the lower inclined back moving groove 280, the turnover pull rod piece 600 continues to move downward, and the turnover pull rod piece 600 moves to the bottom of the upper moving guide groove 210 under the guidance of the lower inclined back moving groove 280; at this time, the turnover action rod unit 430 moves back to the initial position under the pushing of the turnover pull rod piece 600, so as to facilitate the next turnover operation; the adjuster 270 can act on the lower moving positioning guide plate 260 to adjust the lower moving positioning guide plate 260 to be on the upper side of one of the lower moving guide grooves 220, so that when the forging piece is turned over, the turnover pull rod piece 600 automatically moves to the upper side of the corresponding lower moving guide groove 220, and the forging piece can be accurately turned over by a certain angle; by changing the position of the lower moving positioning guide plate 260, the turning angle of the forging piece can be adjusted.

[0035] In one embodiment, as shown in Figures 1-5As shown, the upper horizontal guide groove 240 is internally provided with an upper pressure sensing block 250 corresponding to the upper moving guide groove 210, and the lower moving positioning guide plate 260 has a lower pressure sensor on the end face of the upper moving guide groove 210, and the upper pressure sensing block 250 and the lower pressure sensor are electrically connected with the lifting cylinder 800; in the embodiment of the present application, when the end of the turnover pull rod 600 moves along the upper moving guide groove 210 and moves to the inside of the upper horizontal guide groove 240, the end of the turnover pull rod 600 contacts the upper pressure sensing block 250, the upper pressure sensing block 250 is pressed and generates an induction signal, and the lifting cylinder 800 receives the signal and stops working; at this time, the turnover pull rod 600 is moved under the pushing of the turnover action lever unit 430 and the turnover spring 900, the turnover pull rod 600 moves inside the upper horizontal guide groove 240 and contacts the lower moving positioning guide plate 260, the lower pressure sensor is pressed and generates an induction signal, at this time, the lifting cylinder 800 receives the signal and starts working, the lifting cylinder 800 drives the lifting clamping driving part 500 to move downward, and then the turnover pull rod 600 moves downward along one of the lower moving guide grooves 220, and the movement state of the turnover pull rod 600 is controlled by the upper pressure sensing block 250 and the lower pressure sensor on the surface of the lower moving positioning guide plate 260, so that accurate control can be realized to ensure the accuracy of the turning angle of the forging.

[0036] In one embodiment, as shown in Figures 1-5 The side wall of each lower moving guide groove 220 is provided with a release pressure sensor 290, and the release pressure sensor 290 is located at the bottom of the lower moving guide groove 220 and is electrically connected with the lifting clamping driving part 500; when the turnover pull rod 600 passes through the release pressure sensor 290, the release pressure sensor 290 touches the outer wall of the turnover pull rod 600; in the embodiment of the present application, when the turnover pull rod 600 moves downward from the lower moving guide groove 220 and moves to the inside of the lower inclined back-moving groove 280, the end of the turnover pull rod 600 touches the release pressure sensor 290, the release pressure sensor 290 generates an induction signal, at this time, the forging is on the upper surface of the rotating disc part 110, the lifting clamping driving part 500 works and drives the two clamping parts 400 to move away from each other, so that the two clamping action units 420 quickly release the forging; when the turnover pull rod 600 moves to the inside of the lower inclined back-moving groove 280 and moves along the lower inclined back-moving groove 280 to the upper moving guide groove 210, the turnover of the clamping action unit 420 and the turnover of the forging can be effectively avoided.
