Description

Technical Field

[0001] This utility model relates to the field of die-disassembly technology for forging machines, specifically a die-disassembly mechanism for forging machines. Background Technology

[0002] During the forging process, different materials exhibit varying resistance to deformation. Many factors influence this resistance, such as material temperature, die lubrication, the projected area of ​​the forging, and the actual point of force application. If operation is improper or estimation is incorrect, the forging machine's energy may be insufficient to meet the forming requirements, causing energy loss and machine shutdown. If, after restarting the motor, the slide cannot return to the top dead center, this is called die jamming. When die jamming occurs, disassembly of some parts of the equipment is necessary, but this process is slow, thus affecting processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a die-release mechanism for a forging machine, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The die-release mechanism for the forging machine includes a base, a mounting frame on the base, a main shaft and a crankshaft on the mounting frame, a first gear and a first pulley respectively on both ends of the main shaft, a second gear meshing with the first gear on one end of the crankshaft, a first motor on the mounting frame, a second pulley on the output end of the first motor, the first pulley and the second pulley being connected by a belt, an upper die slidably connected to the mounting frame, a column on the upper surface of the upper die, and a connecting rod, one end of the connecting rod being rotatably connected to the main shaft, and the other end of the connecting rod being rotatably connected to the column, a groove on the upper surface of the base, an upper inclined plate and a lower inclined plate inside the groove, a slide on the lower surface of the lower inclined plate, a recess on the lower surface of the groove, a lead screw threadedly connected to the slide inside the recess, a second motor for driving the lead screw to rotate on one side of the base, and a lower die for cooperating with the upper die on the upper surface of the upper inclined plate.

[0005] Preferably, guide rails are provided on both sides of the upper mold, and guide grooves for sliding of the guide rails are provided on the inner side wall of the mounting frame.

[0006] Preferably, the second motor is disposed on the side of the base away from the lower inclined plate.

[0007] Preferably, the second motor is a geared motor.

[0010] This mold-unlocking mechanism can provide space for the upper inclined plate to move downward by controlling the movement of the lower inclined plate, and can also make the lower mold move downward, thereby solving the mold jamming problem. After the mold is unlocked, it is only necessary to control the reverse rotation of the lead screw to reassemble the upper and lower inclined plates, so that the lower mold can also be quickly reset, reducing the impact on production.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, a die-release mechanism for a forging machine includes a base 1, a mounting frame 2 on the base 1, a main shaft 3 and a crankshaft 4 on the mounting frame 2, a first gear 5 and a first pulley 6 respectively at both ends of the main shaft 3, a second gear 7 meshing with the first gear 5 at one end of the crankshaft 4, a first motor 20 on the mounting frame 2, a second pulley 19 at the output end of the first motor 20, and the first pulley 6 and the second pulley 19 connected by a belt 8. An upper die 9 is slidably connected to the mounting frame 2, and a column 10 is provided on the upper surface of the upper die 9. It also includes a connecting rod 11, one end of which is rotatably connected to the main shaft 3, and the other end of which is rotatably connected to the column 10. The upper surface of the base 1 is provided with a groove, and the inside of the groove is provided with an upper inclined plate 12 and a lower inclined plate 13. The lower surface of the lower inclined plate 13 is provided with a slide block 14. The lower surface of the groove is provided with a recess, and the inside of the recess is provided with a lead screw 15 that is threadedly connected to the slide block 14. A second motor 16 for driving the lead screw 15 to rotate is provided on one side of the base 1. The upper surface of the upper inclined plate 12 is provided with a lower mold 17 for cooperating with the upper mold 9.

[0018] When processing materials using a die forging machine, the heated material is first placed into the upper die 9. Then, the first motor 20 is started, which drives the second pulley 19 to rotate. The second pulley 19 drives the first pulley 6 to rotate via the belt 8. The first pulley 6 drives the main shaft 3 to rotate, which in turn drives the first gear 5 on the main shaft 3 to rotate. The first gear 5 meshes with the second gear 7, which in turn drives the second gear 7 to rotate. The second gear 7 drives the crankshaft 4 to rotate. The rotation of the crankshaft 4 drives the connecting rod 11, the column 10, and the upper die 9 to move up and down. When the upper die 9 moves downward, it can forge the material in the lower die 17, thereby realizing the forging process of the material.

[0019] When the crankshaft 4 and connecting rod 11 in the forging machine get stuck during the forging process, the crankshaft 4 cannot rotate normally. At this time, the second motor 16 can be started. The second motor 16 drives the lead screw 15 to rotate. The lead screw 15 rotates on the base 1. At the same time, due to the threaded connection between the lead screw 15 and the slide 14, and the groove of the base 1 and the upper inclined plate 12 restricting the rotation of the lower inclined plate 13, the lower inclined plate 13 can move linearly along the lead screw 15 through the slide 14. When the lower inclined plate 13 moves out of the groove, there is a certain distance between the upper inclined plate 12 and the lower inclined plate 13. Due to the lack of support from the lower inclined plate 13, the upper inclined plate 12 will move downward under the action of gravity. At the same time, the lower die 17 will also move downward with the upper inclined plate 12, thereby realizing the demolding. If the upper inclined plate 12 and the lower die 17 cannot be demolded, the upper inclined plate 12 and the lower die 17 can be appropriately struck with a hammer or other tools to realize the demolding.

[0020] After the mold is unmolded, the second motor 16 controls the lead screw 15 to rotate in the opposite direction, so that the lower inclined plate 13 re-enters the groove. When the upper inclined plate 12 and the lower inclined plate 13 are completely assembled, they can continue to support the lower mold 17.

[0021] Furthermore, guide rails 18 are provided on both sides of the upper mold 9, and guide grooves for sliding of the guide rails 18 are provided on the inner side wall of the mounting bracket 2, so as to improve the stability of the upper mold 9 when moving and reduce the risk of mold jamming.

[0022] Furthermore, the second motor 16 is located on the side of the base 1 away from the lower inclined plate 13. When the worker is feeding materials on one side of the groove on the base 1, the installation position of the second motor 16 will not obstruct the worker's work.

[0023] Furthermore, the second motor 16 is a geared motor.

[0024] Furthermore, the width at the junction of the lower end of the mounting bracket 2 and the upper opening of the groove is less than the width of the upper inclined plate 12, ensuring that the lower mold 17 is always at the same horizontal height.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
