Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive anti-collision beam stamping technology, and in particular to a continuous stamping die for automotive anti-collision beams. Background Technology
[0002] The anti-collision beam is a very important component of the car body structure, mainly used to absorb and mitigate external impact forces.
[0003] Automotive crash beams are typically made by stamping the two ends of cold-rolled thin steel sheets into an arc-shaped groove structure. This shape provides better structural strength and energy absorption, therefore, stamping dies for automotive crash beams are required.
[0004] Because mounting holes need to be drilled in the car crash beam for later installation via bolts, the current method for stamping car crash beams typically involves first marking positioning holes on a cold-rolled thin steel sheet, then manually drilling the holes with a hand drill. Subsequently, the two ends of the cold-rolled thin steel sheet are stamped into an arc-shaped groove using a stamping die. This method has poor continuity, and the manual drilling method is unstable, greatly reducing the continuity of the stamping process for the car crash beam body and the stamping of the two ends into arc-shaped grooves.
[0005] Therefore, a continuous stamping die for automotive anti-collision beams is needed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a continuous stamping die for automotive anti-collision beams.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] Design a continuous stamping die for an automotive anti-collision beam, including a stamping table, an anti-collision beam body above the stamping table, a die base plate below the stamping table, a rotary motor and a die side plate on the die base plate, a clamping cylinder on the stamping table, a clamping plate on the clamping cylinder, a first stamping cylinder and a second stamping cylinder on the die side plate, a first connecting plate on the first stamping cylinder, a second connecting plate on the second stamping cylinder, a punching die post on the first connecting plate, and a connecting post on the second connecting plate.
[0009] The punching die column is provided with a conical tip, and the connecting column is provided with a stamping die cylinder;
[0010] The mold side plate is provided with a guide groove, and a smoothing layer is provided in the guide groove.
[0011] Furthermore, the stamping table is generally a disc-shaped structure, the vertical central axis of the rotary motor coincides with the vertical central axis of the stamping table, and there is a gap between the anti-collision beam body and the stamping table.
[0012] Furthermore, the clamping cylinder and clamping plate are a set, and there are two sets arranged symmetrically in the longitudinal direction. The side cross-section of the clamping plate is an L-shaped structure and is matched and squeezed into the longitudinal side wall of the anti-collision beam body.
[0013] Furthermore, the punching die post is located at the lower end of the first connecting plate, and the conical tip is located at the lower end of the punching die post.
[0014] Furthermore, the stamping die cylinder and the connecting column are a set, and there are two sets arranged symmetrically. The longitudinal length of the stamping die cylinder is not less than the longitudinal length of the anti-collision beam body.
[0015] Furthermore, the mold side plates are two symmetrical plates, and the guide groove is opened on the mold side plates. The top view of the guide groove is an arc-shaped structure and slides and engages with the outer wall of the stamping table.
[0016] Furthermore, the smoothing layer is uniformly coated along the inner wall of the guide groove, and the smoothing layer is a titanium nitride coating.
[0017] The continuous stamping die for an automotive anti-collision beam proposed in this utility model has the following advantages:
[0018] 1. This utility model sets an electrically controlled rotary stamping table on the mold base plate, and sets a vertically electrically controlled moving punching die column and stamping die cylinder structure above the mold base plate.

After punching is completed, the stamping table is rotated horizontally by 180 degrees and stopped. Finally, the two ends of the anti-collision beam body are simultaneously vertically stamped into arc-shaped groove structures. Overall, the continuity of the punching operation of the car anti-collision beam body and the stamping of the two ends into arc-shaped grooves is improved.
[0019] 2. This utility model greatly improves the stability and guidance of the stamping table during horizontal rotation by using symmetrical mold side plates with guide grooves.
[0020] 3. This utility model further improves the smooth sliding of the stamping table during horizontal rotation along the guide groove by setting a smoothing layer on the inner wall of the guide groove. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figure 1-6 A continuous stamping die for an automotive anti-collision beam includes a stamping table 1, an anti-collision beam body 11 above the stamping table 1, a die base plate 2 below the stamping table 1, a rotary motor 21 and a die side plate 3 on the die base plate 2, a clamping cylinder 4 on the stamping table 1, a clamping plate 41 on the clamping cylinder 4, a first stamping cylinder 5 and a second stamping cylinder 6 on the die side plate 3, a first connecting plate 51 on the first stamping cylinder 5, a second connecting plate 61 on the second stamping cylinder 6, a punching die post 7 on the first connecting plate 51, and a connecting post 8 on the second connecting plate 61.
[0030] The punching die column 7 is provided with a conical tip 71, and the connecting column 8 is provided with a stamping die cylinder 81;
[0031] A guide groove 31 is provided on the side plate 3 of the mold, and a smoothing layer 311 is provided inside the guide groove 31. (See reference) Figure 6This is a schematic diagram of the completed anti-collision beam body 11 after punching and stamping. The anti-collision beam body 11 is made of cold-rolled thin steel sheet for automobiles, which is existing technology.
[0032] The stamping table 1 has a disc-shaped structure. The vertical central axis of the rotary motor 21 coincides with the vertical central axis of the stamping table 1. There is a gap between the anti-collision beam body 11 and the stamping table 1. When punching and stamping are performed, the conical tip 71 and the stamping die cylinder 81 will not collide with the upper surface of the stamping table 1.
[0033] The clamping cylinder 4 and the clamping plate 41 are a set, and there are two sets arranged symmetrically in the longitudinal direction. The side section of the clamping plate 41 is an L-shaped structure and is matched and squeezed to the longitudinal side wall of the anti-collision beam body 11, so as to realize the side wall and bottom support and stable clamping of the anti-collision beam body 11, ensuring the support stability of punching and stamping.
[0034] The punching die 7 is located at the lower end of the first connecting plate 51, and the conical tip 71 is located at the lower end of the punching die 7, so that the punching die 7 can quickly and accurately punch holes through the conical tip 71.
[0035] The stamping die cylinder 81 and the connecting column 8 are a set, and there are two sets in total that are symmetrically arranged. The longitudinal length of the stamping die cylinder 81 is not less than the longitudinal length of the anti-collision beam body 11, so as to ensure that the two sides of the anti-collision beam body 11 are simultaneously and quickly stamped vertically into an arc-shaped groove structure.
[0036] The mold side plates 3 are two symmetrical pieces. The guide grooves 31 are opened on the mold side plates 3. The top view of the guide grooves 31 is an arc-shaped structure and matches and slides with the outer wall of the stamping table 1, so that the stamping table 1 can be stably guided to rotate and slide horizontally along the guide grooves 31 on both sides.
[0037] The smoothing layer 311 is uniformly coated along the inner wall of the guide groove 31. The smoothing layer 311 is a titanium nitride coating. The titanium nitride coating has excellent smoothness, low friction, high hardness, good wear resistance, and high temperature resistance.
[0038] Working method: First, the anti-collision beam body 11, which is to be punched and stamped, is placed horizontally between two clamping plates 41. Then, the clamping cylinder 4 is activated, and the two clamping plates 41 move synchronously to stably clamp the outer wall of the anti-collision beam body 11. Next, the first stamping cylinder 5 is activated, which drives the first connecting plate 51 and the punching die 7 to move downward quickly. When the punching die 7 passes through the anti-collision beam body 11 through the conical tip 71, the punching operation can be realized. Then, the first stamping cylinder 5 drives the punching die 7 to move upward and reset. Next, the rotary motor 21 is activated, which drives the stamping table 1 to rotate horizontally by 180 degrees and stop. Then, the second stamping cylinder 6 is activated, which drives the second connecting plate 61, the connecting column 8, and the stamping die cylinder 81 to move downward quickly as a whole. The stamping die cylinders 81 on both sides can simultaneously vertically stamp the two ends of the lower anti-collision beam body 11 into an arc-shaped groove structure. After the stamping is completed, the second stamping cylinder 6 will drive the stamping die cylinder 81 to move upward and reset.
[0039] The above operations improve the continuity of punching the body 11 of the car anti-collision beam and stamping the two ends into arc-shaped grooves.
[0040] Moreover, when the rotary motor 21 drives the stamping table 1 to rotate horizontally, the stamping table 1 will be stably guided to rotate and slide horizontally along the guide grooves 31 on both sides, which greatly improves the stability and guidance of the stamping table 1 during horizontal rotation.
[0041] In addition, by providing a smoothing layer 311 on the inner wall of the guide groove 31, the smoothness of the stamping table 1 during horizontal rotation along the guide groove 31 is further improved.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
