[0019] The following is in conjunction with the appendix Figure 1-5 The embodiments of the present invention will be described in detail.
[0020] A forging apparatus for magnesium alloy wheels includes a support column 1, a support plate 3 connected to the upper part of the support column 1, a base 2 disposed below the support plate 3, and an adjustment mechanism on the base 2. A lower module 14 and a lower module 27 are mounted on the adjustment mechanism, which adjusts the positions of the lower modules 14 and 27. A notch 11 is provided in the middle of the support plate 3 for either the lower module 14 or the lower module 27 to pass through. At different stages of forging, the lower modules 14 and 27 are assembled outside the support block 13 to form corresponding molds, forging the raw material into the required shape. A hydraulic cylinder 2 12 is disposed in the middle of the upper part of the base 2, and a support block 13 is connected to the piston rod of the hydraulic cylinder 2 12, passing through the notch 11. The support block 13 supports the forging and, after forging is completed, can also lift the wheel hub upwards for easy removal. Guide columns 4 are connected to the upper four sides of the support plate 3. A top plate 5 is connected to the upper part of the guide columns 4. A hydraulic cylinder 6 is installed in the middle of the upper part of the top plate 5. A lifting block 7 is connected to the lower end of the piston rod of the hydraulic cylinder 6. An upsetting head 9 is installed in the middle of the lower part of the lifting block 7. A limit ring 10 is installed on the outer periphery of the upsetting head 9. Under the action of the hydraulic cylinder 6, the lifting block 7 drives the upsetting head 9 and the limit ring 10 to move downward. The upsetting head 9 and the limit ring 10 are used to extrude the blank.
[0021] Preferably, the lifting block 7 is connected to a guide plate 8 on its outer periphery, and the guide post 4 is set through the guide plate 8. The lifting block 7 is guided by the cooperation of the guide post 4 and the guide plate 8 to ensure the vertical descent of the upsetting head 9 and the limiting ring 10, so that the forging of the product is more standardized.
[0022] Preferably, a guide block 41 is fitted on the guide post 4, and a spring 38 is fitted on the guide post 4 between the guide block 41 and the support plate 3. The upper end of the spring 38 is connected to the bottom of the guide block 41, and the lower end of the spring 38 is connected to the upper end face of the support plate 3. A transverse plate 40 is provided between the two guide posts 4 on the left and between the two guide posts 4 on the right. The inner end of the transverse plate 40 is connected to the upper module 39. A linkage block 47 is provided on the upper part of the transverse plate 40. A guide slope is provided on the outer side of the linkage block 47. The guide slope is inclined outward and downward. A hydraulic cylinder 37 is provided on the upper part of the guide plate 8. A storage groove 49 is opened on the guide plate 8 below the hydraulic cylinder 37. The lower end of the piston rod of the hydraulic cylinder 37 extends into the storage groove 49 and is connected to a rotating seat 50. A roller 42 is rotatably arranged in the rotating seat 50. A spring 45 is connected between the transverse plate 40 and the guide block 41. By adding the upper module 39 and making the upper module 39 descend synchronously with the upsetting head 9, the inner shape of the wheel hub can be forged.
[0023] In normal operation, the piston rod of hydraulic cylinder 6 37 is in a retracted state, and roller 42 is located in the receiving groove 49. During the descent of the upsetting head 9, the lifting block 7 contacts the transverse plate 40, causing only the transverse plate 40 to move downwards; the horizontal position of the upper module 39 remains unchanged. When the inner shape of the wheel hub needs to be forged, hydraulic cylinder 6 37 controls its piston rod to extend, causing the rotating seat 50 and roller 42 to move downwards, making roller 42 contact the guide slope of the linkage block 47. During the descent of the lifting block 7, the cooperation between roller 42 and the upper slope of the linkage block 47 causes the transverse plate 40 to move inwards, so that the upper module 39 abuts against the outside of the upsetting head 9, while the upper end of the upper module 39 abuts against the bottom of the limiting ring 10. At this time, the upper module 39 moves downwards along with the upsetting head 9, pressing the forging on the support block 13 to form the inner shape of the forging. After the upsetting head 9 moves upward, the transverse plate 40 moves upward and outward under the action of spring 38 and spring 45 to reset.
[0024] Preferably, a limiting groove 48 is provided on the transverse plate 40 at a position outside the linkage block 47. After the roller 42 descends against the guide slope of the linkage block 47, causing the transverse plate 40 to move inward, the roller 42 falls into the limiting groove 48. The limiting groove 48 limits the roller 42 to a certain extent, so that the roller 42 no longer pushes the transverse plate 40 to move horizontally, but instead drives the transverse plate 40 to move downward.
[0025] Preferably, a mounting block 44 is connected to the lower outer part of the transverse plate 40, and a guide rod 46 is connected to the inner side of the mounting block 44. A guide hole 43 is opened in the guide block 41, and the inner end of the guide rod 46 extends into the guide hole 43. A second spring 45 is sleeved on the guide rod 46, with one end of the second spring 45 connected to the inner side of the mounting block 44 and the other end connected to the outer side of the guide block 41.
[0026] Preferably, the lower part of the guide plate 8 is connected to an abutment post 16. In order to prevent the guide plate 8 from contacting the linkage block 47 during its descent and potentially causing the transverse plate 40 to move inward, the abutment post 16 is set to contact the transverse plate 40 in advance, thus separating the guide plate 8 from the linkage block 47.
[0027] Preferably, the adjustment mechanism includes a support ring 17 located in the middle of the base 2. Two lead screw grooves 18 and 22 are formed on the outer periphery of the support ring 17 on the base 2. The included angle between the lead screw grooves 18 and 22 is 90 degrees. A lead screw 19 is rotatably mounted in the lead screw groove 18. A lead screw slider 20 is mounted on the lead screw 19. A hydraulic cylinder 3 15 is mounted on the upper part of the lead screw slider 20. The upper end of the piston rod of the hydraulic cylinder 3 15 is connected to the lower module 14. A lead screw 23 is rotatably mounted in the lead screw groove 22. The upper part is provided with a lead screw slider 24, and the upper part of the lead screw slider 24 is provided with a hydraulic cylinder 4 26. The upper end of the piston rod of the hydraulic cylinder 4 26 is connected to the lower module 27. The base 2 is provided with a driving mechanism, which drives the lead screw 19 or the lead screw 23 to rotate, thereby adjusting the position of the lead screw slider 10 and the lead screw slider 24 respectively, and then adjusting the position of the lower module 14 and the lower module 27. According to the forging process, the lower module 14 or the lower module 27 passes through the notch 11 and is located on the outer periphery of the support block 13, and is spliced to form the required lower mold.
[0028] Preferably, the inner end of lead screw 19 passes through support ring 17 and is connected to driven bevel gear 21, and the inner end of lead screw 23 passes through support ring 17 and is connected to driven bevel gear 25. The lengths of lead screw 19 and lead screw 23 extending into support ring 17 are different. The drive mechanism includes a base 32 located at the middle position of the upper part of base 2, a hydraulic cylinder 22 located on base 32, a cavity 33 inside base 32, a lifting block 25 inside cavity 33, a hydraulic cylinder 5 34 inside base 32, the upper end of the piston rod of hydraulic cylinder 5 34 connected to the lower end face of lifting block 2 35, an adjusting motor 36 located at the lower part of lifting block 2 35, the adjusting motor 36 driving and connecting to a rotating shaft 30, and a transmission bevel gear 28 and a transmission bevel gear 29 respectively cooperating with driven bevel gear 1 21 and driven bevel gear 25 on the rotating shaft 30. Hydraulic cylinder 5 (34) controls the extension and retraction of the piston rod to control the height of lifting block 2 (35), thereby adjusting the height of transmission bevel gear 1 (28) and transmission bevel gear 2 (29). When transmission bevel gear 1 (28) meshes with driven bevel gear 1 (21), transmission bevel gear 2 (29) disengages from driven bevel gear 2 (25), at which point it independently drives lead screw 1 (19) to rotate, thereby adjusting the position of lower module 1 (14). When transmission bevel gear 1 (28) meshes with driven bevel gear 2 (25), transmission bevel gear 1 (28) disengages from driven bevel gear 2 (21), at which point it independently drives lead screw 2 (23) to rotate, thereby adjusting the position of lower module 2 (27).
[0029] A support seat 31 is provided inside the base 2. The lower end of the rotating shaft 30 is located inside the support seat 31. Several balls are provided on the upper end of the support seat 31 to support the transmission bevel gear 28 after it descends.
[0030] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
