Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold heading machine blanking technology, specifically an adjustable cold heading machine auxiliary blanking device. Background Technology
[0002] Some core functional components of the steering system of new energy vehicles are generally produced using cold heading technology. The parts are made of aluminum alloy. During production on the cold heading machine, at the final station, due to the high pressure of the extrusion, the parts will be attracted to the end face of the mold and cannot fall off by their own weight. Although the attraction between the parts and the mold is not firm, they will not fall off naturally without external intervention, which will prevent the parts from being output smoothly and thus affect the normal progress of the cold heading process.
[0003] Most current cold heading machines have a traditional structural design. The solution to the above problems is to install compressed air nozzles, aim them at the appropriate positions, and rely on the power of compressed air to blow the parts off the mold. This method is unreliable and cannot guarantee that every part will be blown off. If any part fails to fall off, a new part may re-enter the die in subsequent work cycles, causing two parts to enter the final mold at the same time, which can lead to the mold cracking and significant economic losses. To address this, technological innovation should be carried out on the existing equipment. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable auxiliary part-dropping device for cold heading machines to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cold heading machine auxiliary part dropping device, comprising a base, a column fixedly connected to the top of the base, a bracket fixedly connected to the top of the column, the bracket having a cross-section of U-shape, a moving rod fixedly connected to the inner wall of the bracket, a transmission plate fixedly connected to the top of the base, a transmission groove extending to the outside of the transmission plate, and a transmission adjustment device disposed inside the transmission groove.
[0006] Preferably, the transmission adjustment device includes a transmission frame with a U-shaped cross-section. A rotating column is fixedly connected between the transmission frames. A movable plate is rotatably connected to the surface of the rotating column. A fixed block is fixedly connected to the top of the movable plate. The fixed block has a trapezoidal cross-section. A threaded rod extending to the outside is rotatably connected inside the transmission groove. The surface of the threaded rod is threadedly connected to the inside of the transmission frame.
[0007] Preferably, the movable plate has a movable groove extending to its outside, and a movable rod is slidably connected inside the movable groove. The two ends of the movable rod are fixedly connected to the inner wall of the bracket.
[0008] Preferably, the top of the movable plate is provided with a support plate, and the bottom of the support plate is provided with a limiting groove. The cross-section of the limiting groove is also trapezoidal, and the fixed block is slidably connected to the inside of the limiting groove.
[0009] Preferably, the bearing plate has a power groove inside, and a fixed rod extending to the outside is slidably connected inside the power groove. A protrusion is fixedly connected to one side of the fixed rod.
[0010] Preferably, a spring is fixedly connected to one side of the protrusion, and the end of the spring away from the protrusion is fixedly connected to the inner wall of the power groove.
[0011] Preferably, the fixing block below has a fixing groove extending to the outside, the inside of the fixing groove is connected to the inside of the power groove, and the fixing rod is inserted into the inside of the fixing groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1.

This avoids the situation where the workpiece is not pushed out in time, and a new workpiece re-enters the die, causing two workpieces to enter the mold groove of the last station at the same time, which would cause the mold to crack and result in a large economic loss.
[0014] 2.

[0020] Please see Figure 1-4 The present invention provides a technical solution: an adjustable cold heading machine auxiliary part dropping device, including a base 1, a column 3 fixedly connected to the top of the base 1, a bracket 4 fixedly connected to the top of the column 3, the bracket 4 having a cross-section of U-shape, a moving rod 15 fixedly connected to the inner wall of the bracket 4, a transmission plate 5 fixedly connected to the top of the base 1, a transmission groove 7 extending to the outside of the transmission plate, and a transmission adjustment device provided inside the transmission groove 7.
[0021] Please refer to Figure 2 The transmission adjustment device includes a transmission frame 8 with a cross-section of U-shape. A rotating column 9 is fixedly connected between the transmission frames 8. A movable plate 11 is rotatably connected to the surface of the rotating column 9. Two symmetrical fixed blocks 12 are fixedly connected to the top of the movable plate 11. The fixed blocks 12 have a trapezoidal cross-section. A threaded rod 6 extending to the outside is rotatably connected inside the transmission groove 7. The surface of the threaded rod 6 is threadedly connected to the inside of the transmission frame 8. By rotating the threaded rod 6, the operator can drive the transmission frame 8 to reciprocate. The transmission frame 8 can slide the movable plate 11 through the rotating column 9.
[0022] Please refer to Figure 3 The movable plate 11 has a movable groove 14 extending to its outside. A movable rod 15 is slidably connected inside the movable groove 14. The two ends of the movable rod 15 are fixedly connected to the inner wall of the bracket 4. The movable rod 15 can limit the movable plate 11. By sliding the movable plate 11, the movable rod 15 can slide inside the movable groove 14. A bearing plate 10 is provided on the top of the movable plate 11. A pushing mechanism for pushing out parts is provided on the top of the bearing plate 10. The pushing mechanism is an existing structure and will not be described in detail here. Two symmetrical limiting grooves 2 are provided at the bottom of the bearing plate 10. The cross section of the limiting grooves 2 is also trapezoidal. The fixing block 12 is slidably connected to the inside of the limiting grooves 2.
[0023] The operator rotates the threaded rod 6, which drives the transmission frame 8 to reciprocate. The transmission frame 8, through the rotating column 9, drives the moving plate 11 to reciprocate. Under the limit of the moving rod 15, the moving plate 11 can drive the bearing plate 10 to adjust its angle, thereby adjusting the angle of the push-down mechanism. By adjusting the angle of the push-down mechanism, the device can be aligned with the push-down position, accurately pushing the workpiece out of the mold slot. This avoids the situation where a workpiece is not pushed out in time, and a new workpiece re-enters the die, causing two workpieces to enter the mold slot of the final station at the same time, resulting in the mold being cracked and causing significant economic losses.
[0024] Please refer to Figure 4 The bearing plate 10 has a power groove 16 inside. A fixed rod 13 extending to the outside is slidably connected inside the power groove 16. A protrusion 19 is fixedly connected to one side of the fixed rod 13. A spring 17 is fixedly connected to one side of the protrusion 19. The end of the spring 17 away from the protrusion 19 is fixedly connected to the inner wall of the power groove 16. By sliding the fixed rod 13, the spring 17 can be compressed and reset.
[0025] Please refer to Figure 4 The lower fixing block 12 has a fixing groove 18 extending to the outside. The inside of the fixing groove 18 is connected to the inside of the power groove 16. The fixing rod 13 is inserted into the inside of the fixing groove 18.
[0026] By pulling the fixing rod 13, the worker causes the protrusion 19 to slide, compressing the spring 17. The fixing rod 13 then slides out of the fixing groove 18 and is released from its fixation. When the worker releases the fixing rod 13, the spring 17 returns to its original position, allowing the protrusion 19 to be forced to slide the fixing rod 13 into the fixing groove 18 for insertion. By allowing the fixing rod 13 to be inserted into or released from the fixing groove 18, the worker can easily remove the bearing plate 10 from the moving plate 11 for repair or replacement when the pushing mechanism malfunctions and needs maintenance or replacement, effectively extending the service life of the device.
[0027] Working principle: For this type of adjustable cold heading machine auxiliary part-dropping device, the operator first rotates the threaded rod 6, which drives the transmission frame 8 to reciprocate. The transmission frame 8 drives the moving plate 11 to reciprocate through the rotating column 9. Under the limit of the moving rod 15, the moving plate 11 can drive the bearing plate 10 to adjust its angle, thereby adjusting the angle of the pushing mechanism. By adjusting the angle of the pushing mechanism, the device can be aligned with the pushing position. The operator pulls the fixed rod 13, which drives the protrusion 19 to slide, causing the spring 17 to be compressed. The fixed rod 13 slides out of the fixed groove 18 and is released from fixation. The operator releases the fixed rod 13, and the spring 17 returns to its original position, causing the protrusion 19 to be compressed and drive the fixed rod 13 to slide into the fixed groove 18 for insertion.
