Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts processing, in particular to a forming and processing device for side spring pieces of automobile parts. Background Art

[0002] Many automotive power socket shell parts, especially those with critical inner walls, often require side spring forming due to design and usage requirements. Specifically, holes are punched in the side, and then the springs are formed from the inside out. Since the inner diameter of the shell is fixed, the actual processing process is difficult due to the small size of the product parts and limited internal space. This is especially true for continuous stamping dies, which cannot meet the needs of mass production. Due to the limitations of the shell's inner diameter, it is difficult to complete the inside-out forming process using conventional blanking methods. How to achieve an inside-out forming structure within a limited space has become a technical challenge we need to address. Summary of the Invention

DETAILED DESCRIPTION

[0042] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0043] See also Figures 1 to 7As shown, this embodiment provides a molding and processing device for side spring pieces of automobile parts, comprising: an upper molding die mechanism and a lower molding die mechanism suitable for use in conjunction with each other; wherein the upper molding die mechanism is located above the lower molding die mechanism.

[0044] The lower forming die mechanism includes a lower die base, a positioning seat 8 disposed on the lower die base and suitable for supporting and positioning a workpiece 13, a punch slider 9 disposed within the positioning seat 8 and suitable for sliding along the inner diameter of the workpiece 13, and a slider wedge 11 abutting against the punch slider 9. The slider wedge 11 cooperates with the punch slider 9 via an inclined surface, so that the vertical movement of the slider wedge 11 drives the punch slider 9 to generate horizontal movement. It should be noted that the workpiece 13 is suitable for being integrally mounted on the positioning seat 8, so that the positioning seat 8 plays a role in positioning and supporting the workpiece 13 during the processing process.

[0045] Regarding the lower mold base of this embodiment, considering the convenience of assembling the lower mold base with the remaining structures, the lower mold base of this embodiment includes a lower base 15 and a lower pad 16 matched with the lower base 15, and a slider seat 17 matched with the side of the lower pad 16 facing away from the lower base 15, wherein the positioning seat 8 is arranged on the slider seat 17.

[0046] Specifically, a protrusion 10 protrudes from one side end face of the punch slider 9 along the inner diameter of the workpiece 13, adapted to extend outside the positioning seat 8. In other words, an opening is provided in the side wall of the positioning seat 8 for the protrusion 10 to pass through. In other words, as the punch slider 9 moves, the protrusion 10 switches between two states: extending outside the positioning seat 8 and being accommodated within the positioning seat 8. When the protrusion 10 extends outside the positioning seat 8, it is used to punch a spring piece against the side wall of the workpiece 13.

[0047] Furthermore, an inclined contact surface 14 is provided on the end face of the punch slider 9, adapted to mate with the slider wedge 11. A first spring 12 is also located within the positioning seat 8, one end of which abuts against the slider wedge 11. As the protrusion 10 of the punch slider 9 gradually extends out of the positioning seat 8, the slider wedge 11 moves toward the first spring 12, compressing and deforming the first spring 12. Therefore, the return action of the first spring 12 can be used to reset the punch slider 9.

[0048] Secondly, the lower forming die mechanism of this embodiment further includes a lower stripper plate 18 connected to the lower die base via an elastic component and adapted to support the workpiece 13 from the bottom end thereof. The positioning seat 8 extends through the lower stripper plate 18. In other words, when the workpiece 13 is completely sheathed on the positioning seat 8, the lower stripper plate 18 is used to support the workpiece 13 from the bottom end thereof. As the lower stripper plate 18 descends toward the lower base 15, the workpiece 13 is gradually sheathed on the positioning seat 8. As the lower stripper plate 18 ascends away from the lower base 15, it can drive the workpiece 13 away from the positioning seat 8.

[0049] In an optional implementation, the elastic component includes a second spring 20 that is arranged through the lower base 15 and the lower pad 16, and a lifting rod 19 connected to one end of the second spring 20. The lifting rod 19 passes through the lower pad 16 and the slider seat 17 at the same time, and the end of the lifting rod 19 away from the second spring 20 extends out of the slider seat 17 to connect to the lower unloading plate 18.

[0050] Regarding the upper forming die mechanism of this embodiment, it includes an upper die base, an upper ejector pin 7 and an upper push rod 6 disposed on the upper die base and protruding toward the lower die base. Similarly, considering the ease of assembly of the upper die base with the remaining components, the upper die base of this embodiment includes an upper base 1, an upper pad 2 connected to the side of the upper base 1 facing the lower base 15, and an upper fixed plate 3 connected to the side of the upper pad 2 facing the lower base 15. The upper ejector pin 7 penetrates both the upper fixed plate 3 and the upper pad 2 and then engages with a third spring 22 intersecting the upper pad 2 and the upper base 1. The upper push rod 6 penetrates the upper fixed plate 3 and then engages with a fourth spring 21 intersecting the upper base 1, the upper pad 2, and the upper fixed plate 3.

[0051] During the gradual closing of the upper and lower forming mold mechanisms (closing herein refers to the process in which the upper forming mold mechanism presses down on the lower forming mold mechanism), the upper ejector pin 7 is adapted to push the workpiece 13 onto the positioning seat 8; while the upper ejector pin 6 is adapted to push the lower stripper plate 18 to move the lower stripper plate 18 toward the lower mold base, thereby compressing the second spring 20. It should be noted that, in the parting state of the upper and lower forming mold mechanisms, the height of the upper ejector pin 6 relative to the upper mold base is greater than the height of the upper ejector pin 7 relative to the upper mold base. The significance of this design is that, on the one hand, there is a height difference between the end of the lower stripper plate 18 contacting the upper push rod 6 and the end of the workpiece 13 contacting the upper ejector rod 7. Therefore, the height difference is compensated by the height of the upper ejector rod 6 protruding relative to the upper mold base being greater than the height of the upper ejector rod 7 protruding relative to the upper mold base; on the other hand, the upper ejector rod 6 acts on the lower stripper plate 18 first to reduce the resistance of the lower stripper plate 18 to the downward movement of the workpiece 13 when the upper ejector rod 7 pushes the workpiece 13 onto the positioning seat 8.

[0052] The power for the movement of the punch slider 9 of this embodiment is achieved through the following structure:

[0053] Specifically, the lower forming die mechanism of this embodiment further includes at least one ejector pin 23 disposed on the lower die base and located on the side of the locating seat 8 facing away from the raised portion 10 of the punch slider 9, and an ejector slider 24 connected to the at least one ejector pin 23 and adapted to drive the ejector pin 23 to perform linear motion along the inner diameter direction of the workpiece 13; wherein the ejector pin 23 is adapted to penetrate the side wall of the workpiece 13 and then abut against the side end of the punch slider 9 facing away from the raised portion 10. With reference to the drawings of this embodiment, taking two ejector pins 23 as an example, a through hole suitable for the two ejector pins 23 to pass through is provided on the side end of the locating seat 8 facing away from the punch slider 9. Of course, a through hole suitable for the two ejector pins 23 to pass through is also provided on the side wall of the workpiece 13. In other words, the two ejector pins 23 are gradually inserted into the locating seat 8 under the action of the ejector slider 24 to achieve the effect of driving the movement of the punch slider 9 built into the locating seat 8.

[0054] The power for the movement of the ejector slider 24 is achieved in this embodiment through the following structure: Specifically, the upper forming mold mechanism further includes a second inclined wedge 5 protruding from the upper fixed plate 3 toward the lower mold base, adapted to abut against the ejector slider 24; the ejector slider 24 and the second inclined wedge 5 are adapted to cooperate through inclined surfaces, so that the vertical movement of the second inclined wedge 5 drives the ejector slider 24 to produce horizontal movement; the ejector slider 24 is provided with a second slider inclined surface 25 for cooperating with the second inclined wedge 5, wherein the second slider inclined surface 25 is provided on the ejector slider 24 at a side end thereof facing away from the ejector 23; and the second inclined surface 26 is provided on the second inclined wedge 5 adapted to engage with the second slider inclined surface 25. In other words, as the upper forming mold mechanism moves toward the lower forming mold mechanism, the second inclined wedge 5 moves downward synchronously with the upper base 1. During this process, as the second inclined wedge 5 moves downward, the ejector slider 24 produces horizontal movement toward the positioning seat 8, causing the ejector 23 to gradually insert into the positioning seat 8, thereby producing a pushing effect on the punch slider 9.

[0055] The reset process of the push rod slider 24 is achieved through the following structure: a fifth spring 27 is connected to the side end surface of the push rod slider 24 facing away from the positioning seat 8. The fifth spring 27 is accommodated in a fifth spring sleeve 34. The fifth spring sleeve 34 is fixed to the accommodating box that accommodates the push rod slider 24 through a fifth spring stopper 28. That is, one end of the fifth spring 27 penetrates the fifth spring stopper 28 and the side wall of the accommodating box before being connected to the push rod slider 24. With this structure, as the push rod slider 24 moves toward the positioning seat 8, the fifth spring 27 is stretched. After the pushing force of the second wedge 5 on the push rod slider 24 disappears, the reset action of the fifth spring 27 can cause the push rod slider 24 to reset synchronously.

[0056] Furthermore, the lower forming die mechanism of this embodiment also includes a spring-type forming die 29 disposed on the lower die base and located on one side of the positioning seat 8, and a die slider 31 connected to the spring-type forming die 29 to drive the spring-type forming die 29 to perform linear motion along the inner diameter direction of the workpiece 13; wherein the spring-type forming die 29 is provided with a recessed cavity 30 suitable for inserting the protrusion 10 on the side end facing the protrusion 10. In detail, the spring-type forming die 29 of this embodiment is mainly used to form a supporting effect on the side wall of the workpiece 13 except for the spring-type processing area during the processing of the workpiece 13, so as to avoid deformation of the side wall of the workpiece 13 during the processing. That is, when the protrusion 10 enters the recessed cavity 30, the side end surface of the spring-type forming die 29 facing the workpiece 13 except for the recessed cavity 30 is tightly attached to the outer wall of the workpiece 13.

[0057] As for the power of the movement of the die slider 31, this embodiment is achieved through the following structure: Specifically, the upper forming mold mechanism of this embodiment also includes a first inclined wedge 4 protruding from the upper fixed plate 3 toward the side of the lower mold base and suitable for abutting and cooperating with the die slider 31; wherein the die slider 31 and the first inclined wedge 4 are suitable for cooperating through inclined surfaces to drive the die slider 31 to produce horizontal movement through the vertical movement of the first inclined wedge 4.

[0058] In detail, the side end of the die slider 31 of this embodiment facing away from the workpiece 13 is provided with a first slider inclined surface 33 for cooperating with the first inclined wedge 4; and the first inclined wedge 4 is provided with a first lower inclined surface 36 suitable for fitting with the first slider inclined surface 33 and a first upper inclined surface 35 located above the first lower inclined surface 36; wherein the first lower inclined surface 36 and the first upper inclined surface 35 are distributed in parallel, and a flat end surface 37 suitable for being parallel to the flat end portion of the side end of the die slider 31 facing away from the workpiece 13 is transitioned between the first lower inclined surface 36 and the first upper inclined surface 35.

[0059] It should be noted that the first inclined wedge 4 of this embodiment is provided with two sections of inclined surface structure, while the second inclined wedge 5 is only provided with one section of inclined surface structure. The significance of this arrangement is that the first inclined wedge 4 and the second inclined wedge 5 are synchronously realized with the downward movement of the upper base 1 to realize the downward process. During this process, the push rod 23 needs to be inserted into the positioning seat 8 and then push the punch slider 9 in the positioning seat 8. The spring-formed die 29 is abutted against the workpiece 13 after moving to the side wall of the workpiece 13 and no longer moves. Therefore, the overall die slider 31 is compared with the push rod slider 24. The moving trajectory of the die slider 31 is shorter than the moving trajectory of the push rod slider 24. Therefore, the first inclined wedge 4 of this embodiment is provided with two sections of inclined surface structure, and a transitional flat end surface 37 is provided between the inclined surface structures at both ends, which can be used to coordinate the difference in the moving trajectory of the die slider 31 and the push rod slider 24. That is, when the spring sheet forming die 29 remains in contact with the side wall of the workpiece 13, the push rod 23 can continue to push the punch slider 9 under the action of the push rod slider 24, so that the protrusion 10 on the punch slider 9 gradually enters the recessed cavity 30 of the spring sheet forming die 29 to complete the stamping process of the workpiece 13.

[0060] The reset process of the die slider 31 is achieved through the following structure: a sixth spring 38 is connected to the side end surface of the die slider 31 facing away from the positioning seat 8. The sixth spring 38 is accommodated in a sixth spring sleeve 39. The sixth spring sleeve 39 is fixedly connected to the accommodating chamber that accommodates the die slider 31 via a sixth spring stopper 40. That is, one end of the sixth spring 38 mates with the die slider 31 after passing through the sixth spring stopper 40 and the side wall of the accommodating chamber. With this structure, as the die slider 31 moves toward the positioning seat 8, the sixth spring 38 is stretched. After the thrust of the first wedge 4 on the die slider 31 disappears, the reset action of the sixth spring 38 can cause the die slider 31 to reset synchronously.

[0061] The specific implementation principle of the molding and processing device for the side spring piece of an automobile part of this embodiment is as follows:

[0062] See also Figures 4 to 7 As shown in the figure, the process of the upper forming die mechanism moving toward the lower forming die mechanism is as follows:

[0063] The workpiece 13 to be processed is placed above the positioning seat 8, so that the lower stripper plate 18 forms a support for the bottom of the workpiece 13. The punch slide drives the upper die base to move toward the lower die base. As the upper die base descends, the upper push rod 6 pushes the lower stripper plate 18, and the upper push rod 7 gradually pushes the workpiece 13 onto the positioning seat 8 until the workpiece 13 is completely fitted on the positioning seat 8, and the positioning process of the workpiece 13 is completed.

[0064] The upper die base continues to move downward, and the third spring 22 connected to the upper ejector pin 7 and the fourth spring 21 connected to the upper push rod 6 are gradually compressed. The first inclined wedge 4 drives the die slider 31 to move toward the positioning seat 8. At this time, the spring-piece forming die 29 connected to the die slider 31 gradually approaches the workpiece 13. Synchronously, the second inclined wedge 5 drives the ejector slider 24 to move toward the positioning seat 8, and causes the ejector pin 23 to gradually insert into the positioning seat 8 to push the punch slider 9, so that the protrusion 10 on the punch slider 9 gradually extends into the concave cavity 30 of the spring-piece forming die 29, thereby completing the side spring piece forming of the workpiece 13. At this point, the downward movement process of one stamping is completed.

[0065] For the process of the upper forming die mechanism moving away from the lower forming die mechanism:

[0066] The punch slider drives the upper die base to move upward, the first inclined wedge 4 gradually leaves the die slider 31, and the second inclined wedge 5 gradually leaves the ejector slider 24. At this time, the die slider 31 is gradually reset under the reset action of the sixth spring 38, and the ejector slider 24 is gradually reset under the reset action of the fifth spring 27. In this process, the ejector 23 is gradually reset along with the ejector slider 24, and since the effect of the ejector 23 on the punch slider 9 gradually disappears, the punch slider 9 is also gradually reset under the action of the first spring 12 and the slider inclined wedge 11, and is finally completely retracted into the positioning seat 8.

[0067] The upper die base continues to move upward, the upper ejector rod 7 gradually leaves the workpiece 13, and the upper push rod 6 gradually leaves the lower unloading plate 18. The lower unloading plate 18 is gradually reset under the action of the lifting rod 19 and the second spring 20. In this process, the lower unloading plate 18 gradually lifts the processed workpiece 13 away from the positioning seat 8.

[0068] The punch press returns to the highest point and completes a complete punching process. At this time, the workpiece 13 that has completed the shrapnel forming process is sent to the next station by the feeder, and another workpiece 13 that has not completed the shrapnel forming process is continued to be sent to the shrapnel forming processing station to continue the same processing process.
