Description

Technical Field

[0001] The invention relates to the technical field of coupling tooth processing, and in particular to a forming fine punching die for a deep groove type coupling tooth. Background Art

[0002] The gear teeth of the gearbox are used for speed shifting during the body forming process. When processing the gear teeth of the automobile gearbox, the blank is usually pre-forged into a blank or the blank is precision stamped by a punch press, and the teeth are punched and cut by a stamping die, and then the teeth are ground and formed by a machine tool.

[0003] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. The stamping die consists of a fixed part and a movable part. The fixed part is fastened to the workbench of the press with a pressing plate, bolts, etc. The movable part is generally fastened to the slide of the press. There are many types of stamping dies, including blanking dies, drawing dies, bending dies, flanging dies, curling dies, etc. They are widely used in various fields, including automobiles, electronics, and daily hardware.

[0004] For example, a medium and thick plate forming precision stamping die with application number CN216501806U and announcement date 2022.05.13 includes an upper die base, a lower die base, and a plurality of first guide members arranged between the upper die base and the lower die base, and a front punch module group and a forming module group are arranged in sequence between the upper die base and the lower die base according to the moving direction of the material plate; the front punch module group includes a first punch, which is arranged on the lower surface of the upper die base, a first stripper plate, which is nested on the first punch, and a first concave template, which is arranged on the lower die base below the first punch, and is connected to the first stripper plate through a second guide member; the forming module includes a second punch, which is arranged on the lower surface of the upper die base, a second stripper plate, which is nested on the second punch, and a lower concave die assembly, which is arranged on the lower die base below the second punch. With the cooperation of the lower concave die assembly, the second punch cuts the material from the material plate and stamps it into one piece.

[0038] In an embodiment provided by the present invention, ear plates 34 are fixedly provided on the outer walls on both sides of the top plate 7, and guide columns 35 are fixedly provided on the outer wall of the top of the base 1, and the two guide columns 35 are located on both sides of the lower guide frame 2, and the ear plates 34 are slidably sleeved on the outside of the guide columns 35, and the top ends of the guide columns 35 are provided with anti-slip caps 37, and the anti-slip caps 37 are located on the top ends of the ear plates 34, and the anti-slip caps 37 are located on the top ends of the ear plates 34, and the buffer springs 36 are provided on the outer walls of the top ends of the base 1, and the top ends of the buffer springs 36 are fixedly provided on the outer walls of the bottom ends of the ear plates 34, and the buffer springs 36 are sleeved on the outside of the guide columns 35, and when the top plate 7 descends, the elastic force of the buffer springs 36 can buffer the ear plates 34 and the top plate 7, and can reduce the punching force generated when the upper mold 10 and the lower mold 4 overlap, thereby protecting the upper mold 10 and the lower mold 4.

[0039] Working principle: Place the raw material ring of the combined tooth in the groove of the lower mold 4, open the hydraulic cylinder 6 to drive the top plate 7 to descend, and the top plate 7 drives the upper guide frame 8 and the upper mold 10 to descend. Before the upper mold 10 contacts the lower mold 4, the upper guide frame 8 will first enter the anti-deep groove 38 to mesh the upper teeth 9 with the lower teeth 3, which can guide and limit the top plate 7 and the upper mold 10, and can avoid the phenomenon of the punching knife 39 offset and punching failure. With the downward movement of the upper mold 10 and the punching knife 39, the tooth groove of the combined tooth can be punched. Since the center position of the lower mold 4 is raised, it can be realized. Now, for the deep groove punching of the combined teeth, when the top plate 7 descends, the elastic force of the buffer spring 36 can buffer the ear plate 34 and the top plate 7, and then can buffer the punching force generated between the descending upper mold 10 and the lower mold 4, and can play a buffering and protective role on the upper mold 10 and the lower mold 4. After the punching is completed, the hydraulic cylinder 6 is turned on to drive the top plate 7 to move up, the top plate 7 drives the guide block 11 to move up, the guide block 11 drives the connecting block 12 and the lifting plate 13 to move up, and the lifting plate 13 generates a thrust on the lifting plate 15, which can push the lifting plate 15, the top block 16 and the ejector plate 17 to rise. The coupling teeth can be ejected from the lower die 4, which is convenient for cutting the coupling teeth. There is no need to use tools to clamp the coupling teeth out of the lower die 4, which is more convenient. After the lifting plate 13 is lowered and the lifting plate 15 is not pushed, the elastic force of the push-back spring 19 can push the lifting plate 15 down, and the lifting plate 15 drives the ejection block 16 and the ejection plate 17 to move down and return to their positions, waiting for the next ejection. When the types of coupling teeth to be punched are different, the punching requirements are also different, and the upper die 10 and the lower die 4 need to be replaced. Turning the long neck screw 26 drives the movable plate 24 and the insert block 25 to move, so that the insert block 25 can be removed from the raised portion. 22, pull the upper mold 10 downward to remove the upper mold 10 from the top plate 7, replace the upper mold 10, thread the assembling screws 21 out from the top of the assembly block 20 and the top block 16, now remove the ejector plate 17 from the top block 16, push the push plate 33, the push plate 33 drives the connecting rod 32, the guide plate 29 and the anti-slip block 30 to move, so that the anti-slip block 30 can be moved out of the assembly block 27, pull the lower mold 4 upward, the lower mold 4 can be removed from the base 1, and the upper mold 10 and the lower mold 4 can be replaced according to the different types of coupling teeth to be processed, and the scope of use is wider.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
