Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a wedge positioning structure for stamping dies of automotive body panels. Background Technology

[0002] A wedge is an important component in automotive body panel stamping dies. In practical use, the main function of a wedge is to change the stamping direction, for example, converting the vertical stamping motion of the press into a horizontal or inclined motion, thereby changing the stamping direction.

[0003] When in use, the wedge needs to be fixedly mounted on a positioning fixture. The main function of the positioning fixture is to ensure the wedge's position is determined, thereby ensuring that the wedge's change in the stamping direction is consistent during use. Current conventional positioning fixtures are only for a specific angle, and the corresponding wedge shape is also fixed. This means that in actual use, when encountering wedges with different tilt angles, the positioning fixture also needs to be replaced, greatly increasing production difficulty. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wedge positioning structure for automotive body panel stamping dies that can automatically adjust the angle to automatically adapt to different wedge parameters.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wedge positioning structure for stamping mold of automotive body panels, including a base plate and a wedge. A fixed plate is provided on the base plate. The first side of the wedge is closely attached to the fixed plate. A rotating plate is included. The rotating plate is rotatably set. The wedge is set between the fixed plate and the rotating plate. The second side of the wedge is closely attached to the rotating plate. The intersection of the extension line of the fixed plate and the extension line of the rotating plate is set below the wedge.

[0006] Furthermore, it includes a rotating plate fixing seat, which is fixedly mounted on the base plate, and the rotating plate is rotatably mounted on the rotating plate fixing seat.

[0007] Furthermore, a rotating plate connecting block is provided on the side of the rotating plate facing the rotating plate fixing seat, and the rotating plate connecting block is rotatably mounted on the bearing seat of the rotating plate fixing seat via a bearing.

[0008] Furthermore, a lower limiting block is provided on the base plate, which is located between the fixed plate and the rotating plate fixing seat; when the rotating plate rotates to be in close contact with the lower limiting block, the rotating plate stops rotating in the original direction.

[0009] Furthermore, an upper limiting block is provided at the top of the rotating plate fixing seat; when the rotating plate rotates to be in close contact with the upper limiting block, the rotating plate stops rotating in the original direction.

[0010] Furthermore, a forklift bay is provided at the bottom of the base plate.

[0011] The beneficial effects of this invention are as follows: In actual use, because the rotating plate can rotate, when the wedge is placed between the fixed plate and the rotating plate, under the action of gravity, the second side of the wedge is tightly attached to the rotating plate, and the first side of the wedge is tightly attached to the fixed plate. Simultaneously, the intersection of the extension lines of the fixed plate and the rotating plate is located below the wedge, creating a funnel-like structure with an overall upward opening between the fixed plate and the rotating plate, thus encompassing the wedge. Under the action of gravity, the wedge is locked within this funnel-like structure, achieving a stable locking state. Furthermore, even if the angle between the first and second sides of a new wedge changes after replacement, when the new wedge is placed between the fixed plate and the rotating plate, the rotating plate's rotation will automatically create a new stable locking state, achieving automatic adjustment and positioning of wedges of different sizes and specifications. This greatly improves the versatility in actual use and increases production efficiency. This invention is particularly suitable for stamping automotive body panels where frequent replacement of different wedges is required. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the inclined wedge of this utility model.

[0014] The markings in the diagram are as follows: forklift slot 1, base plate 2, lower limit block 3, fixed plate 4, rotating plate fixing seat 5, rotating plate connecting block 6, bearing seat 7, upper limit block 8, wedge 9, first side 91, second side 92, wedge connecting end 93, rotating plate 10, and wedge connecting rod 11. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2 The illustrated automotive body panel stamping die wedge positioning structure includes a horizontally arranged base plate 2. A pair of forklift slots 1 are fixedly installed at the bottom of the base plate 2. When a forklift is inserted into the forklift slots 1, the base plate 2 and the components above it can be securely transported. Figure 1 As shown, a fixing plate 4 is provided on the left side of the base plate 2. The fixing plate 4 is set in the vertical direction, and a reinforcing rib is provided on the side of the fixing plate 4 facing away from the wedge 9 to ensure the stability of the fixing plate 4 when it is tightly attached to the first side 91 of the wedge 9. The bottom of the fixing plate 4 is fixed to the base plate 2 by fastening screws.

[0017] like Figure 1 As shown, a rotating plate fixing seat 5 is provided on the right side of the base plate 2. The bottom of the rotating plate fixing seat 5 is fixed to the base plate 2 by fastening screws. A bearing seat 7 is provided on the side wall of the rotating plate fixing seat 5 facing the rotating plate 10. The bearing seat 7 and the connecting block 6 at the bottom of the rotating plate 10 are rotatably connected to the rotating plate 10 through the bearing, that is, the rotating plate 10 rotates around the bearing, thereby realizing the angle adjustment to adapt to different types of wedges 9.

[0018] like Figure 1 As shown, a lower limiting block 3 is provided between the fixed plate 4 and the rotating plate fixing seat 5, and the lower limiting block 3 is set on the base plate 2. An upper limiting block 8 is provided on the top of the rotating plate fixing seat 5. During the rotation of the rotating plate 10 around the bearing, the lower limiting block 3 and the upper limiting block 8 respectively constrain the two rotation directions of the rotating plate 10. Specifically, when the rotating plate 10 rotates counterclockwise until it is in close contact with the lower limiting block 3, the rotating plate 10 stops rotating counterclockwise. When the rotating plate 10 rotates clockwise until it is in close contact with the upper limiting block 8, the rotating plate 10 stops rotating clockwise. Within the rotation range of the above two rotation directions, a suitable wedge 9 is matched.

[0019] Figure 1 and Figure 2 The wedge 9 shown includes a first side 91 and a second side 92. The first side 91 is tightly attached to the fixed plate 4, and the second side 92 is tightly attached to the rotating plate 10. In actual use, after the wedge 9 is placed between the fixed plate 4 and the rotating plate 10, the second side 92 of the wedge 9 will slide downwards along the rotating plate 10 under the action of gravity. During the sliding process, the rotating plate 10 will also rotate. When it rotates to a certain angle, the wedge 9 will lock between the fixed plate 4 and the rotating plate 10. At this time, the intersection of the extension line of the plane where the fixed plate 4 is located and the extension line of the plane where the rotating plate 10 is located is located below the wedge 9. Thus, the wedge 9 is automatically positioned. After replacing the wedge 9, the new wedge 9 generally refers to a change in the included angle between the first side 91 and the second side 92. When the new wedge 9 is placed between the fixed plate 4 and the rotating plate 10, the rotating plate 10 will also rotate. However, when the wedge 9 is finally locked between the fixed plate 4 and the rotating plate 10, the tilt angle of the rotating plate 10 will be different from the tilt angle of the rotating plate 10 corresponding to the original wedge 9, but both are within the rotation range of the rotating plate 10, thus realizing automatic adjustment and positioning of different wedges 9. After locking the wedge 9, the corresponding wedge connecting rod 11 is connected to the wedge connecting end 93 at the top of the wedge 9, and the next operation can be performed.
