Technical Field
[0001] The utility model belongs to the technical field of forging and processing of drive shaft parts, and particularly relates to a trimming device for forging and processing a fork-type flange. Background Technique
[0002] The fork-type flange is an important part of the drive shaft. During its processing, in order to ensure its quality, forging is mostly used for processing. Forging is a processing method that uses forging machinery to apply pressure to a metal blank, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. At the same time, forging processing can eliminate defects such as as-cast porosity generated during the smelting process of metals and optimize the microstructure. Therefore, the mechanical properties of forgings are generally better than those of castings made of the same material. However, after forging, there will be certain flash on the edges of the forgings. Therefore, after the forging and processing of the forgings, trimming processing needs to be carried out on them. Most of the existing trimming methods are manual trimming. When this method is specifically used, it has poor safety, is time-consuming and laborious, and has low work efficiency. Therefore, in order to solve the above problems, it is very necessary to develop a trimming device for forging and processing a fork-type flange that is convenient to operate, use, safe and efficient. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a trimming device for forging and processing a fork-type flange that is convenient to operate, use, safe and efficient.
[0004] The purpose of the utility model is achieved as follows: A trimming device for forging and processing a fork-type flange includes a bearing bottom plate, a top plate, a pressure plate, a cylinder, a trimming female die and a trimming male die. At both ends of the lower surface of the bearing bottom plate, supports are fixedly arranged, and at the center of the lower surface, a U-shaped mounting member is fixedly arranged. At the center of the upper surface, a placement groove is arranged, and at both ends of the upper surface, guiding support plates are vertically and fixedly arranged. Inside the placement groove, a top block matching its structure is arranged, and at the center of the bottom surface of the groove, a through hole is arranged. A connecting rod is slidably inserted through the through hole. Between the upper end of the connecting rod and the lower surface of the top block, an elastic member is vertically fixedly arranged, and the lower end protrudes from the through hole and is located below the bearing bottom plate and is fixedly connected to an intermediate plate. Between the lower surface of the intermediate plate and the inner bottom surface of the U-shaped mounting member, an electric push rod is vertically fixedly arranged. The top plate and the bearing bottom plate are in a flat shape and are fixedly arranged at the upper ends of the two guiding support plates. The pressure plate is located between the bearing bottom plate and the top plate. At both ends of its upper surface, connection grooves matching the structures of the guiding support plates are arranged, and through the cooperation and socket connection of the two connection grooves and the two guiding support plates, its sliding installation between the two guiding support plates is completed. The cylinder is vertically fixedly arranged in the middle between the top plate and the pressure plate. The trimming female die is fixedly arranged at the center of the upper surface of the bearing bottom plate. The trimming male die is located directly above the trimming female die and is fixedly connected to the lower surface of the pressure plate.
[0005] The elastic member is composed of a guiding telescopic rod and a return spring sleeved outside the guiding telescopic rod.
[0006] A calibration groove is longitudinally arranged on the outer side surface of the guiding support plate.
[0007] An inclined reinforcing rod is fixedly arranged at the connection between the upper end of the outer side surface of the guiding support plate and the lower surface of the top plate.
[0008] The beneficial effects of the present utility model: By providing a top plate, a pressing plate and a cylinder, using the telescopic property of the cylinder, the pressing plate and the trimming punch fixedly arranged on the lower surface of the pressing plate can be driven to move in the vertical direction, and then by the movement of the trimming punch, through its cooperation with the trimming die, trimming processing is carried out on the fork-shaped flange forging placed inside the trimming die; By providing a guiding support plate and a connecting groove, using the fitting and sleeving of the guiding support plate and the connecting groove, while not affecting the vertical movement of the pressing plate, a guiding and limiting effect can be achieved on the pressing plate, avoiding the problem that during long-term use, due to the deviation of the position of the pressing plate, it affects the subsequent trimming operation of the trimming punch and the trimming die;
[0009] By providing a placement groove, an ejector block, a through hole, an elastic member, a connecting rod, an intermediate plate and an electric push rod, during the process that the cylinder contracts and drives the pressing plate and the trimming punch to move upward after the trimming processing of the fork-shaped flange forging is completed, the thrust of the elastic member when reset and unfolded can be used to drive the ejector block to move upward, and then through the upward movement of the ejector block, the ejecting operation of the fork-shaped flange forging inside the trimming die is completed. With this structure, after the trimming processing is completed, the elastic member can automatically eject the fork-shaped flange forging, increasing the convenience of operation and use of the present utility model. At the same time, when the connection between the fork-shaped flange forging and the trimming die is relatively tight, resulting in the inability to directly eject the fork-shaped flange forging by the thrust of the elastic member, the electric push rod can be controlled to expand, and by the expansion of the electric push rod, the connecting rod, the elastic member and the ejector block can be driven to move in the vertical direction, and then the ejecting operation of the fork-shaped flange forging inside the trimming die is completed; Generally, the present utility model has the advantages of convenient operation, use, safety and high efficiency.

[0014] The following further describes the present utility model with reference to the accompanying drawings.
[0015] Embodiment: As Figure 1 , Figure 2 , Figure 3 shown, a trimming device for fork flange forging processing includes a bearing bottom plate 1, a top plate 2, a pressing plate 3, a cylinder 4, a trimming concave die 5 and a trimming convex die 6. At both ends of the lower surface of the bearing bottom plate 1, supports 11 are fixedly arranged, and a U-shaped mounting piece 12 is fixedly arranged at the center of the lower surface. A placing groove 13 is arranged at the center of the upper surface, and guide support plates 14 are vertically and fixedly arranged at both ends of the upper surface. An ejecting block 15 matching with its structure is arranged inside the placing groove 13, and a through hole 16 is arranged at the center of the groove bottom surface. A connecting rod 17 is slidably inserted through the through hole 16. An elastic member 18 is vertically fixedly arranged between the upper end of the connecting rod 17 and the lower surface of the ejecting block 15, and the lower end protrudes out of the through hole 16 and is located below the bearing bottom plate 1 and fixedly connected with an intermediate plate 19. An electric push rod 7 is vertically fixedly arranged between the lower surface of the intermediate plate 19 and the inner bottom surface of the U-shaped mounting piece 12; the top plate 2 and the bearing bottom plate 1 are in a flat shape and are fixedly arranged at the upper ends of the two guide support plates 14. The pressing plate 3 is located between the bearing bottom plate 1 and the top plate 2. Connecting grooves 31 matching with the structure of the guide support plates 14 are arranged at both ends of the upper surface, and the pressing plate 3 is slidably installed between the two guide support plates 14 through the cooperation of the two connecting grooves 31 and the two guide support plates 14; the cylinder 4 is vertically fixedly arranged in the middle between the top plate 2 and the pressing plate 3. The trimming concave die 5 is fixedly arranged at the center of the upper surface of the bearing bottom plate 1. The trimming convex die 6 is located directly above the trimming concave die 5 and is fixedly connected with the lower surface of the pressing plate 3.
[0016] The elastic member 18 is composed of a guiding telescopic rod and a return spring sleeved outside the guiding telescopic rod; a calibration groove 141 is longitudinally arranged on the outer side surface of the guide support plate 14; a slanting reinforcing rod 21 is fixedly arranged at the connection between the upper end of the outer side surface of the guide support plate 14 and the lower surface of the top plate 2. The reinforcing rod 21 can be used to increase the connection stability between the guide support plate 14 and the top plate 2.
[0017] When the utility model is in use, first, place the fork-shaped flange forging to be processed on the trimming die 5. At this time, under the elastic action of the elastic member 18, the lower end of the fork-shaped flange forging only contacts the ejector block 15 protruding outside the placement groove 13 and has not contacted the pressure-bearing bottom plate 1 yet. Then, control the cylinder 4 to expand. By using the thrust of the cylinder 4 on the pressure plate 3 when it expands, the pressure plate 3 and the trimming punch 6 fixedly arranged on the lower surface of the pressure plate 3 can be driven to move vertically downward. As the trimming punch 6 moves downward and presses on the fork-shaped flange forging in the trimming die 5, the elastic member 18 can be contracted, and the fork-shaped flange forging and the ejector block 15 move downward. After the ejector block 15 moves downward into the placement groove 13, by using the supporting effect of the pressure-bearing bottom plate 1 and the ejector block 15 and the cooperation of the trimming die 5 and the trimming punch 6, the trimming operation of the fork-shaped flange forging can be completed under the pressing action of the trimming punch 6. Finally, after the trimming of the fork-shaped flange forging is completed, control the cylinder 4 to contract. The contraction of the cylinder 4 can drive the pressure plate 3 and the trimming punch 6 to move upward. During this process, by using the thrust of the elastic member 18 when it resets and expands on the ejector block 15, the ejector block 15 can be driven to move upward, and thus, through the upward movement of the ejector block 15, the ejection operation of the fork-shaped flange forging inside the trimming die 5 can be completed. With this structure, the utility model can automatically eject the fork-shaped flange forging by using the elastic member 18 after the trimming process, increasing the convenience of operation and use of the utility model. At the same time, when the connection between the fork-shaped flange forging and the trimming die 5 is relatively tight and the fork-shaped flange forging cannot be directly ejected by the thrust of the elastic member 18, the electric push rod 7 can be controlled to expand. By using the expansion of the electric push rod 7, the connecting rod 17, the elastic member 18, and the ejector block 15 can be driven to move in the vertical direction, and thus, the ejection operation of the fork-shaped flange forging inside the trimming die 5 can be completed. Moreover, by setting the guiding support plate 14 and the connecting groove 31, and using the fitting and sleeving of the guiding support plate 14 and the connecting groove 31, the pressure plate 3 can be guided and limited while not affecting the vertical movement of the pressure plate 3, avoiding the problem that the position of the pressure plate 3 shifts during long-term use and affecting the subsequent trimming operation of the cooperation between the trimming punch 6 and the trimming die 5. Generally, the utility model has the advantages of convenient operation, use, safety, and high efficiency.
