DETAILED DESCRIPTION
[0024] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0025] like Figure 1 As shown, workpiece 1 passes through a cold bending forming machine and a straightening mechanism, and then enters a notching die for notching. Since the tool shears and squeezes the workpiece, the fracture will be deformed after the workpiece is notched, and the workpiece opens at a certain angle at the cross section. At this time, when the workpiece continues to move forward in the notching die concave die, it will press against the die on the discharge side, resulting in material resistance.
[0026] See also Figure 2-Figure 9 , the utility model provides a technical solution for solving the deformation problem of the workpiece 1:
[0027] like Figure 2-Figure 9As shown, a feed auxiliary device for a recessing die is used for assisting the discharge of a workpiece 1 after the recess. The workpiece 1 includes a first folding edge 101, a second folding edge 102, a third folding edge 103, a fourth folding edge 104, a fifth folding edge 105, a sixth folding edge 106 and a seventh folding edge 107. The device includes a recessing die 4, a first top block 402 and a second top block 403. The recessing die 4 is provided with a discharge cavity 406 adapted to the size of the workpiece 1. The first top block 402 and the second top block 403 are symmetrically arranged on both sides of the concave die of the recessing die 4 and are located in front of the discharge cavity 406. Telescopic cylinders 404 are respectively provided on the outer sides of the first top block 402 and the second top block 403. The cylinder seats of the two telescopic cylinders 404 are respectively fixed to the outer wall of the recessing die 4, and the piston rods of the two telescopic cylinders 404 are respectively connected to the first top block 402 and the second top block 403.
[0028] Through the above technical solution, the workpiece 1 passes through the cold bending forming main machine 2 and the straightening mechanism 3 and enters the withdrawal die 4 for withdrawal. When the workpiece 1 is withdrawn in the concave die of the withdrawal die 4 and is ready to enter the discharge cavity 406, the first top block 402 and the second top block 403 are moved toward the workpiece 1 located in the middle by the telescopic cylinder 404. The first top block 402 and the second top block 403 are adjusted to be just on both sides of the opening of the discharge cavity 406. At this time, the expanded workpiece 1 is pushed inward by the first top block 402 and the second top block 403, and the deformation of the workpiece 1 after withdrawal is eliminated by the first top block 402 and the second top block 403, so that the workpiece 1 can smoothly enter the discharge cavity 406. The problems of material blocking and material clogging caused by the withdrawal deformation of the workpiece 1 are avoided, the failure rate is reduced, and the production efficiency is improved.
[0029] Furthermore, the size of the first top block 402 on the side close to the discharge cavity 406 is adapted to the shape formed by the first fold 101, the second fold 102 and the third fold 103, and the size of the second top block 403 on the side close to the discharge cavity 406 is adapted to the shape formed by the fifth fold 105, the sixth fold 106 and the seventh fold 107.
[0030] Through the above technical scheme, the abutting shape of the first top block 402 and the workpiece 1 is just the standard shape surrounded by the first folded edge 101, the second folded edge 102 and the third folded edge 103. The first top block 402 can restore the deformed first folded edge 101, the second folded edge 102 and the third folded edge 103. Similarly, the abutting shape of the second top block 403 and the workpiece 1 can restore the deformed fifth folded edge 105, the sixth folded edge 106 and the seventh folded edge 107.
[0031] Furthermore, an auxiliary positioning component 5 is provided in the second top block 403, and the auxiliary positioning component 5 includes a lever 501, a slider 502 and a limit block 503. The lever 501 is located on the side of the second top block 403 corresponding to the fourth folded edge 104, the middle part of the lever 501 is hinged to the inside of the second top block 403, and a first spring 504 is provided above the lever 501, one end of the first spring 504 is connected to the lever 501, and the other end of the first spring 504 is connected to the second top block 403, the lever 501 extends out of the second top block 403, and the second top block 403 is provided with a slot corresponding to the position of the lever 501.
[0032] Furthermore, the slider 502 is located on the side of the second top block 403 corresponding to the fifth folding edge 105, and the bottom of the second top block 403 is provided with a slide rail 507 that cooperates with the slider 502. The slider 502 is slidably connected to the second top block 403 through the slide rail 507. One end of the slider 502 abuts against the lever 501. A second spring 505 is provided between the slider 502 and the slide rail 507, one end of the second spring 505 is fixed to the slide rail 507, and the other end of the second spring 505 is fixed to the slider 502.
[0033] Furthermore, a first inclined surface 508 is provided at one end of the slider 502 away from the lever 501, and a second inclined surface 509 matching the first inclined surface 508 is provided at one end of the limit block 503 close to the slider 502. The limit block 503 is located on a side of the second top block 403 corresponding to the fourth folded edge 104, and a limit cavity 510 is provided at a position of the second top block 403 corresponding to the limit block 503. The limit block 503 slides along the limit cavity 510, and a third spring 506 is provided between the limit block 503 and the second top block 403, one end of the third spring 506 is fixed to the inner wall of the second top block 403, and the other end of the third spring 506 is fixed to the limit block 503.
[0034] Through the above technical solution, in the actual retreat process, the fourth fold 104 will be deformed, and the second top block 403 can only reset the fifth fold 105, the sixth fold 106 and the seventh fold 107, so the fourth fold 104 is reset by the positioning auxiliary component.
[0035] Specifically, the telescopic cylinder 404 is activated to push the second top block 403 toward the workpiece 1. At this time, the sixth folded edge 106 first contacts the extended end of the lever 501. At this time, the lever 501 is extended from the second top block 403 by the elastic force of the first spring 504. As the second top block 403 moves, the lever 501 is squeezed by the sixth folded edge 106 and the first spring 504 is compressed. Since the middle part of the lever 501 is hinged, the other end of the lever 501 rotates accordingly, thereby pushing the slider 502 to move along the slide rail 507 in a direction away from the lever 501.
[0036] In the initial state, the second spring 505 pulls the slider 502 through elastic force, and the slider 502 and the limit block 503 are not in contact. However, as the lever 501 abuts, the slider 502 compresses the second spring 505 and slides toward the limit block 503. At this time, the first inclined surface 508 and the second inclined surface 509 are in contact. Through the cooperation of the inclined surfaces, and at the same time, the limit block 503 is restricted to sliding up and down by the limit cavity 510, so as the slider 502 moves to the left, the limit block 503 will move upward.
[0037] In the initial state, the limit block 503 is contracted in the second top block 403 by the elastic force of the third spring 506 , but as the second inclined surface 509 on the slider 502 abuts, the limit block 503 compresses the third spring 506 , and at the same time, the limit block 503 extends out of the second top block 403 .
[0038] During the process of the lever 501 being moved and the slider 502 sliding, the limit block 503 gradually extends out of the limit cavity 510, and the limit block 503 abuts against the fifth fold edge during the extension process, and can also straighten the fifth fold edge. Until the sixth fold edge 106 is in contact with the second top block 403, the lever 501 is parallel to the sixth fold edge 106, and the limit block 503 is extended to the maximum state. The distance from the limit block 503 to the lever 501 is just the length of the fifth fold edge 105, so the limit block 503 just abuts against the fourth fold edge 104. With the extrusion of the second top block 403, the fourth fold edge 104, the fifth fold edge 105, the sixth fold edge 106 and the seventh fold edge 107 are reset in the standard shape formed by the second top block 403, eliminating deformation and being able to smoothly enter the discharge side of the lower die.
[0039] When the second top block 403 retreats, the limit block 503 is reset and retracted into the second top block 403 under the elastic force of the third spring 506, the slider 502 moves away from the limit block 503 under the elastic force of the second spring 505, and the lever 501 continues to extend out of the second top block 403 under the elastic force of the first spring 504 to facilitate the next work.
[0040] Furthermore, an exhaust hole 401 is provided above the knife plate of the exhaust mold 4, and the other end of the exhaust hole 401 extends into the concave mold of the exhaust mold 4, and the other end of the exhaust hole 401 is connected to an air pipe and an air source.
[0041] Through the above technical solution, the exhaust hole 401 is connected to the air pipe and the external air source, so that the cavity of the retreating mold 4 can be ventilated to clean the residue in the cavity of the retreating mold 4.
[0042] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
