Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and relates to an internal wedge stamping mechanism for a stamping die for an automotive wing-shaped reinforcing plate. Background Technology

[0002] In industrial production, parts are often stamped using stamping dies. Because the two sides of the automotive wing plate reinforcement plate are sloping, after the first stamping is completed, a second set of dies is needed to stamp the sloping wing plate a second time, which is a complex process and has high equipment costs.

[0003] For example, a Chinese patent discloses a stamping die for automotive parts [application number: 201820680118.7], which includes a rectangular die body. The die body includes a plurality of spaced support plates at the bottom and a die cavity formed at the top. The outer side of the die cavity has guide posts for cooperating with the punch body. The outer side of the guide posts has limit blocks. A feed port is formed on one side of the die cavity, and an outlet is formed on the opposite side of the feed port. The outlet is provided with a sliding plate with an adjustable angle. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing an internal wedge stamping mechanism for stamping dies of automotive wing-shaped reinforcing plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An internal wedge stamping mechanism for a stamping die for an automotive fender reinforcement plate includes a stamping seat and a lower die seat fixed on an upper die. The lower die seat is provided with a stamping forming surface composed of two inclined stamping parts and one forward stamping part. The two inclined stamping parts are respectively arranged on both sides of the forward stamping part and are symmetrically arranged. The stamping seat and the forward stamping part are arranged correspondingly. An embedded inclined stamping mechanism corresponding to the inclined stamping parts is also provided between the upper die and the lower die seat.

[0007] In the aforementioned wedge-type stamping mechanism of the automotive wing-shaped reinforcing plate stamping die, the embedded inclined stamping mechanism includes an upper stamping component disposed on the upper die and a lower stamping component disposed on the lower die base. The lower die base is provided with an inclined guide structure corresponding to the upper stamping component, and the upper die is also provided with a drive component corresponding to the lower stamping component.

[0008] In the aforementioned wedge-type stamping mechanism of the automotive fender reinforcement stamping die, the upper stamping assembly includes an upper wedge block mounting seat that is horizontally slidably disposed on the upper die, an inclined upper wedge block that is fixed at the bottom of the upper wedge block mounting seat, and an upper stamping surface at the bottom end of the upper wedge block.

[0009] In the aforementioned wedge-type stamping mechanism of the automotive fender reinforcement stamping die, the inclined guide structure includes a guide seat fixed directly below the upper wedge block mounting seat. The guide seat is fixed on the lower die seat, and the guide seat is provided with an inclined guide surface corresponding to the upper wedge block. When the upper die moves vertically upward, the inclined guide surface on the guide seat can drive the upper wedge block to move obliquely downward toward the inclined stamping part.

[0012] In the aforementioned wedge-type stamping mechanism of the automotive fender reinforcement stamping die, the lower stamping assembly includes a lower wedge block inclinedly disposed in the lower die base. The top of the lower wedge block has a lower stamping surface. A lower wedge block drive seat is also horizontally slidably disposed on the lower die base. A lower wedge block lifting structure is disposed between the lower wedge block drive seat and the lower wedge block.

[0013] In the aforementioned wedge-type stamping mechanism of the automotive fender reinforcement stamping die, the lower wedge lifting structure includes a lower wedge pusher fixed to the bottom end of the lower wedge and a lower wedge top block fixed to the lower wedge drive seat.

[0014] In the aforementioned wedge-type stamping mechanism of the automotive fender reinforcement stamping die, the driving component includes a pressure block fixed to the bottom of the upper die, an upper driving block with a first inclined extrusion surface at the bottom fixed to the pressure block, and a lower driving block with a second inclined extrusion surface at the top fixed to the outer end of the lower wedge drive seat.

[0015] In the aforementioned wedge-type stamping mechanism of the automotive wing-shaped reinforcing plate stamping die, a return spring connected to the lower die base is fixedly connected to the inner end of the lower wedge block drive seat.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. The stamping seat on the upper die, together with the forward stamping part on the lower die seat, can stamp and form the main body of the car wing reinforcement plate. The embedded inclined stamping mechanism corresponding to the inclined stamping part can stamp and form the inclined wing plates on both sides of the main body at the same time as stamping and forming the main body of the car wing reinforcement plate. No secondary stamping is required, which can reduce processing steps and reduce equipment costs.

[0018] 2. When the upper die and the lower die base are stamping, the lower stamping component on the upper die, together with the inclined guide structure, can move obliquely downward in the direction of the inclined stamping part. The driving component on the upper die can drive the lower stamping component to move obliquely upward in the direction of the inclined stamping part. The upper stamping component and the lower stamping component work together to realize the stamping forming of the two side wing plates of the main body.

[0024] like Figures 1-4 As shown, an internal wedge stamping mechanism for a car fender reinforcement stamping die includes a stamping seat 1 and a lower die seat 2 fixed on an upper die. The lower die seat 2 is provided with a stamping forming surface composed of two inclined stamping parts 3 and one forward stamping part 4. The two inclined stamping parts 3 are respectively arranged on both sides of the forward stamping part 4 and are symmetrically arranged. The stamping seat 1 and the forward stamping part 4 are arranged correspondingly. An embedded inclined stamping mechanism 5 corresponding to the inclined stamping parts 3 is also provided between the upper die and the lower die seat 2.

[0025] In this invention, the stamping seat 1 on the upper die, together with the forward stamping part 4 on the lower die seat 2, can stamp and form the main body of the car wing reinforcement plate. The embedded inclined stamping mechanism 5, corresponding to the inclined stamping part 3, can stamp and form the inclined wing plates on both sides of the main body while stamping and forming the main body of the car wing reinforcement plate. No secondary stamping is required, which can reduce processing steps and reduce equipment costs.

[0026] Specifically, the embedded tilting stamping mechanism 5 includes an upper stamping component 6 mounted on an upper die and a lower stamping component 7 mounted on a lower die base 2. The lower die base 2 is provided with a tilting guide structure 8 corresponding to the upper stamping component 6, and the upper die is also provided with a drive component 9 corresponding to the lower stamping component 7. When the upper die and the lower die base are stamping, the lower stamping component 7 on the upper die, in conjunction with the tilting guide structure 8, can move obliquely downward in the direction of the tilting stamping section. The drive component 9 on the upper die can drive the lower stamping component 7 to move obliquely upward in the direction of the tilting stamping section. The upper stamping component and the lower stamping component work together to realize the stamping forming of the two side wing plates of the main body.

[0027] Specifically, the upper stamping assembly 6 includes an upper wedge block mounting seat 10 that is horizontally slidably disposed on the upper die. An inclined upper wedge block 11 is fixed at the bottom of the upper wedge block mounting seat 10. The bottom end of the upper wedge block 11 has an upper stamping surface. The inclined guide structure 8 includes a guide seat 12 fixed directly below the upper wedge block mounting seat 10. The guide seat 12 is fixed on the lower die seat 2. An inclined guide surface 13 corresponding to the upper wedge block 11 is disposed on the guide seat 12. When the upper die moves vertically upward, the inclined guide surface 13 on the guide seat 12 can drive the upper wedge block 11 to move obliquely downward toward the inclined stamping part 3. When the upper die and the lower die base are stamping, the upper wedge block on the upper wedge block mounting base 10 can move obliquely downward towards the inclined stamping part 3 under the action of the inclined guide surface 13 on the guide seat. Two limiting pressure plates 14 fixed on the upper die are provided on both sides of the upper wedge block mounting base 10. The upper wedge block mounting base 10 is slidably disposed between the limiting pressure plate 14 and the upper die. During the movement of the upper wedge block, the upper wedge block mounting base 10 moves horizontally between the limiting pressure plate and the upper die.

[0028] Specifically, the top of the upper wedge block mounting base 10 is recessed inward with an elastic element mounting groove 15. An elastic element is disposed within the elastic element mounting groove 15. The elastic element includes a spring mounting base 16 fixedly connected to the upper wedge block mounting base 10. A return shaft 17 connected to a spring is disposed within the spring mounting base 16. A connecting block 18 connected to the upper punch is fixedly connected to the outer end of the return shaft 17. After the upper punch and lower die base separate, the upper wedge block mounting base can be translated and reset under the action of the spring and the return shaft 17 within the spring mounting base 16.

[0029] Specifically, the lower stamping assembly 7 includes a lower wedge 19 inclinedly disposed within the lower die base 2. The lower wedge 19 has a lower stamping surface at its top. A lower wedge drive seat 20 is also horizontally slidably disposed on the lower die base 2. A lower wedge lifting structure is disposed between the lower wedge drive seat 20 and the lower wedge 19. The lower wedge lifting structure includes a lower wedge pusher 21 fixed to the bottom end of the lower wedge 19 and a lower wedge top block 22 fixed to the lower wedge drive seat 20. The lower wedge pusher 21 and the lower wedge top block 22 are correspondingly disposed, and inclined push surfaces 23 are correspondingly disposed on the lower wedge pusher 21 and the lower wedge top block 22. When the lower wedge drive seat moves into the lower die base, the inclined push surfaces on the lower wedge top block and the lower wedge pusher 22 cooperate to drive the lower wedge 19 to move obliquely upward toward the inclined stamping part 3.

[0030] Specifically, the drive assembly 9 includes a pressure block 24 fixed to the bottom of the upper die, an upper drive block 26 with a first inclined extrusion surface 25 at the bottom fixed to the pressure block 24, and a lower drive block 28 with a second inclined extrusion surface 27 at the top fixed to the outer end of the lower wedge drive seat 20. When the upper die and the lower die seat are stamping, the pressure block 24 on the upper die can move downward. When the pressure block moves downward, the first inclined extrusion surface 25 on the upper drive block 26, in conjunction with the second inclined extrusion surface on the lower drive block 28, can drive the lower wedge drive seat 20 to translate into the interior of the lower die seat.

[0031] Specifically, a return spring connected to the lower mold base 2 is fixed to the inner end of the lower wedge drive seat 20. After the upper drive block 26 and the lower drive block 28 disengage, the return spring can drive the lower wedge drive seat 20 to move outward and reset.

[0032] The working principle of this utility model is as follows: the stamping seat 1 on the upper die, together with the forward stamping part 4 on the lower die seat 2, can stamp and form the main body of the car wing plate reinforcement plate. The embedded inclined stamping mechanism 5, corresponding to the inclined stamping part 3, can stamp and form the inclined wing plates on both sides of the main body while stamping and forming the main body of the car wing plate reinforcement plate. No secondary stamping is required, which can reduce processing steps and reduce equipment costs.

[0033] When the upper die and the lower die base are stamping, the lower stamping component 7 on the upper die, in conjunction with the inclined guide structure 8, can move obliquely downward in the direction of the inclined stamping part. The driving component 9 on the upper die can drive the lower stamping component 7 to move obliquely upward in the direction of the inclined stamping part. The upper stamping component and the lower stamping component can cooperate to realize the stamping forming of the wing plates on both sides of the main body. When the upper die and the lower die base are stamping, the upper wedge block on the upper wedge block mounting seat 10 can move obliquely downward in the direction of the inclined stamping part 3 under the action of the inclined guide surface 13 on the guide seat. During the movement of the upper wedge block, the upper wedge block mounting seat 10 moves horizontally between the limiting pressure plate and the upper die. After the upper die and the lower die base are separated, the upper wedge block mounting seat can be translated and reset under the action of the spring and the return shaft 17 in the spring mounting seat 16.

[0034] When the lower wedge drive seat moves into the lower die holder, the inclined push surface on the top block of the lower wedge and the inclined push surface on the push block of the lower wedge can cooperate to drive the lower wedge 19 to move obliquely upward towards the inclined stamping part 3. When the upper die and the lower die holder are stamping, the pressure block 24 on the upper die can move downward. When the pressure block moves downward, the first inclined extrusion surface 25 on the upper drive block 26 and the second inclined extrusion surface on the lower drive block 28 can cooperate to drive the lower wedge drive seat 20 to move into the lower die holder. After the upper drive block 26 and the lower drive block 28 are separated, the return spring can drive the lower wedge drive seat 20 to move outward and reset.
