Description

Technical Field

[0001] The invention relates to the technical field of forging, and in particular to a gearbox bracket forging device. Background Art

[0002] The gearbox crossbeam bracket is used to provide auxiliary support for the gearbox, which can reduce the load on the engine suspension. When manufacturing the gearbox bracket, the corresponding plate needs to be forged into a forging of a certain shape, and then fine-processed.

[0003] In the process of forging plates into forgings, a forging press is required. When the upper limit travel switch of the top cylinder in the forging press is abnormal, excessive pressure is applied to the workpiece. Since the existing mold is fixedly installed and cannot be moved down away from the punch head, the pressure applied to the mold cannot be removed in time. As the pressure applied by the punch head increases, the workpiece or even the mold will be damaged, causing great losses. For this reason, we proposed a gearbox bracket forging device.

[0017] (III) Beneficial effects

[0018] The present invention provides a gearbox bracket forging device, which has the following beneficial effects:

[0019] 1. By adding a workbench, an adjustment mechanism and a pressure relief mechanism, the plate to be forged is placed in the lower die, and the adjustment mechanism is controlled to drive the upper die head to move downward to forge the plate. When the pressure is too high, the pressure sensor transmits a signal to the electric push rod 1, and the pressure relief mechanism moves the lower die downward to keep it away from the upper die head, which can effectively prevent the upper die head from crushing the forging and the lower die, reducing losses.

[0020] 2. By adding a lifting mechanism, when the lower mold needs to be restored to its original position, start motor one, and drive the shaft to rotate through the transmission of gear three and gear two, thereby driving gear one to rotate, which can drive the gear rod to move up, and the lower mold fixed with the gear rod can be moved up to a suitable position. There is no need to manually lift the lower mold, which simplifies the operation and reduces the work intensity.

[0021] 3. By adding a buffer mechanism, when the top support rod moves down and contacts the load-bearing rod, the impact force between the top support rod and the load-bearing rod is reduced under the action of the damper and the spring, which plays a shock-absorbing and buffering role, preventing damage to corresponding components caused by excessive impact.

[0022] 4. By adding the ejector part, after the forging is completed, when the upper feeler leaves the lower die, under the elastic force of spring 2, the ejector head moves up and ejects the forging part out of the lower die, so that the staff can take out the forging more easily.

[0023] 5. By adding a transfer mechanism, the vacuum suction cup is first controlled to move to the top of the positioning groove to adsorb the plate, and the adsorbed plate is transferred to the lower die. After the forging is completed, the vacuum suction cup can be controlled to adsorb the forging and then transfer it out of the range of the upper die head. There is no need to manually put the plate into the lower die or take out the forging from the lower die, which reduces safety hazards.

[0024] In summary, the present invention can effectively prevent the upper die from crushing the forging and the lower die, thereby reducing losses and also reducing potential safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Example 1

[0041] like Figure 1-Figure 12As shown, a gearbox bracket forging device includes a workbench 1, a lower die 3 arranged on the workbench 1, an upper die head 2 and an adjusting mechanism 4 for driving the upper die head 2. A cavity 101 is arranged in the workbench 1, and a pressure relief mechanism 5 for removing the pressure of the lower die 3 is arranged in the cavity 101. Among them, the adjusting mechanism 4 is used to control the upper die head 2 to move downward, and the forging of the plate can be completed in combination with the lower die 3 to obtain a bracket forging. When the hydraulic rod 43 in the adjusting mechanism 4 fails, such as when the cylinder is pushed, the pressure generated by the upper die head 2 is too large, which may crush the forging, and even the lower die 3. At this time, the pressure relief mechanism 5 will start, so that the lower die 3 moves downward, which can effectively prevent the damage of the forging and the lower die 3 and reduce the loss.

[0042] The pressure relief mechanism 5 includes a plurality of top sleeve rods 53 fixed in the cavity 101, on which a top support rod 51 is slidably mounted, the top support rod 51 is fixed to the lower mold 3, and a notch 52 is provided on the top support rod 51, an abutment plate 54 for supporting the top support rod 51 is provided in the top sleeve rod 53, a pressure sensor 59 is installed on the abutment plate 54, a guide roller 510 for relative movement with the abutment plate 54 is installed at the bottom end of the top support rod 51, so as to facilitate relative movement of the abutment plate 54 and the top support rod 51, and bearing rods 55 are fixed at both ends of the abutment plate 54, the width of the bearing rod 55 is smaller than the width of the notch 52, so that the notch 52 passes through the bearing rod 55, a sliding sleeve 56 is slidably mounted on the bearing rod 55, the sliding sleeve 56 is fixed to the cavity 101, the same connecting rod 57 is fixed on the plurality of front side bearing rods 55, and an electric push rod 58 for driving the connecting rod 57 is installed in the cavity 101. Among them, after the upper die head 2 moves down and cooperates with the lower die 3 to complete the forging, the upper die head 2 continues to move down due to a malfunction, and the pressure on the lower die 3 continues to increase. At this time, the pressure sensor 59 reaches the set pressure, and the movable rod of the electric push rod 58 retracts, driving the abutment plate 54 to move forward and disengage from the bottom end of the top support rod 51. At this time, under the action of gravity, the top support rod 51 and the lower die 3 thereon move downward, so as to move away from the upper die head 2, which can effectively prevent the upper die head 2 from crushing the forging and the lower die 3, thereby reducing losses.

[0043] A buffer mechanism 6 for shock absorption and buffering is arranged in the notch 52. When the pressure relief mechanism 5 and the lower mold 3 suddenly move downward, the buffer mechanism 6 contacts the bearing rod 55 to play a role of shock absorption and buffering, preventing the corresponding parts from being damaged due to excessive impact.

[0044] In summary, the plate to be forged is placed in the lower die 3, and the adjusting mechanism 4 is controlled to drive the upper die head 2 to move downward to forge the plate. When the pressure is too high, the pressure sensor 59 transmits a signal to the electric push rod 58, and the pressure relief mechanism 5 moves the lower die 3 downward to move away from the upper die head 2, which can effectively prevent the upper die head 2 from crushing the forging and the lower die 3, thereby reducing the loss.

[0045] Furthermore, two sets of ejection parts 9 are provided in the lower die 3, and the ejection part 9 includes a slideway 91 opened in the lower die 3, an ejection head 92 is slidably installed in the slideway 91, a spring 2 94 is fixed between the ejection head 92 and the slideway 91, and a limiting column 93 is fixed in the slideway 91. During forging, the plate drives the ejection head 92 to move downward until the bottom end of the ejection head 92 abuts against the top end of the limiting column 93, at which time the top end of the ejection head 92 is flush with the inner wall of the lower die 3. After the forging is completed, when the upper die 2 leaves the lower die 3, under the elastic force of the spring 2 94, the ejection head 92 moves upward to eject the forging part out of the lower die 3, so that the staff can take out the forging more easily.

[0046] Specifically, the adjustment mechanism 4 includes a plurality of columns 41 fixed on the workbench 1, and the plurality of columns 41 are sequentially arranged at the four corners of the top of the workbench 1. The tops of the plurality of columns 41 are fixed with a same support plate 42, on which a hydraulic rod 43 is mounted, the upper die head 2 is fixed with the movable end of the hydraulic rod 43, and a support rod 44 slidably mounted with the column 41 is mounted on the upper die head 2. The upper die head 2 can be driven to move up or down by starting the hydraulic rod 43, and the support rod 44 plays the role of auxiliary limit support, which improves the stability of the upper die head 2 when it moves down forging.

[0047] Example 2

[0048] refer to Figure 7-Figure 8 , which is basically the same as the embodiment 1, and is more optimized in that the buffer mechanism 6 includes a damper 61 installed in the notch 52, a buffer plate 62 is fixed to the other end of the damper 61, a rubber pad 64 is fixed to the bottom end of the buffer plate 62, and a spring 1 63 is sleeved on the damper 61, and the spring 1 63 is fixed between the notch 52 and the buffer plate 62. Among them, when the top support rod 51 moves downward until the rubber pad 64 contacts the bearing rod 55, under the action of the damper 61 and the spring 1 63, the impact force between the top support rod 51 and the bearing rod 55 is reduced, which plays a role in shock absorption and buffering, and prevents the corresponding components from being damaged due to excessive impact.

[0049] Example 3

[0050] refer to Figure 3-Figure 7, which is basically the same as the embodiment 1, but is more optimized in that a lifting mechanism 7 for lifting the lower mold 3 is provided in the cavity 101, and the lifting mechanism 7 includes a rotating shaft 71 rotatably installed in the cavity 101, and a plurality of gears 1 72 are sleeved and installed on the rotating shaft 71, and a gear rod 73 is meshed on the gear 1 72, and the gear rod 73 is fixed to the lower mold 3, and a motor 1 76 for driving the rotating shaft 71 to rotate is installed in the cavity 101. Specifically, a gear 3 75 is fixed to the output end of the motor 1 76, and a gear 2 74 is meshed on the gear 3 75, and the gear 2 74 is sleeved and installed on the rotating shaft 71. Among them, when the device maintenance is completed and the lower mold 3 needs to be restored to its original position, the motor 1 76 is started, and the transmission of the gear 3 75 and the gear 2 74 drives the shaft 71 to rotate, thereby driving the gear 1 72 to rotate, and the gear rod 73 can be driven to move up, and the lower mold 3 fixed with the gear rod 73 can be moved up. After moving to the appropriate position, the electric push rod 1 58 is controlled to make the abutment plate 54 move back to the bottom of the top support rod 51. At this time, the motor 1 76 is controlled to reverse, driving the lower mold 3 and the top support rod 51 thereon to move downward until the bottom end of the top support rod 51 contacts the abutment plate 54, and then the motor 1 76 is powered off. There is no need to manually lift the lower mold 3, which simplifies the operation and reduces the work intensity.

[0051] Example 4

[0052] refer to Fig.10 , which is basically the same as the embodiment 1, but is more optimized in that a transfer mechanism 8 is provided on the workbench 1, and the transfer mechanism 8 includes two support blocks 81 fixed on the top of the workbench 1, a screw 82 is rotatably mounted on the support block 81, and a guide rod 83 is fixed on the support block 81, a moving rod 85 is threadedly mounted on the screw 82, the moving rod 85 and the guide rod 83 are slidably mounted, and an electric push rod 86 is installed on the moving rod 85, and a vacuum suction cup 87 is installed on the movable end of the electric push rod 86, a motor 84 for driving the screw 82 to rotate is installed on the support block 81, and a positioning groove 88 for placing the plate is opened on the top of the workbench 1. Among them, when the staff manually takes and places objects from the lower mold 3, the upper mold head 2 may cause damage to the staff, which poses a great safety hazard. The staff can put the plate to be forged into the positioning groove 88, start the motor 84, drive the screw 82 to rotate, and then drive the moving rod 85, the electric push rod 86 and the vacuum suction cup 87 thereon to move in the front and rear directions, control the electric push rod 86 to drive the vacuum suction cup 87 to move in the vertical direction, first control the vacuum suction cup 87 to move above the positioning groove 88, adsorb the plate, and move the adsorbed plate to the lower die 3. After the forging is completed, the vacuum suction cup 87 can be controlled to adsorb the forging and then move it out of the range of the upper die head 2. There is no need to manually put the plate into the lower die 3 or take out the forging from the lower die 3, thereby reducing safety hazards.
