Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a non-die stamping die for processing an anti-collision beam mounting plate. Background Art

[0002] At present, under the background of the industry development of lightweight automobiles and expanding the application of aluminum, the application of aluminum alloy anti-collision beams is becoming more and more widespread. The aluminum alloy anti-collision beam assembly is mainly composed of two mounting plates, an energy absorption box and a main beam. Among them, the mounting plate is used as a connecting part of the anti-collision beam assembly to the vehicle body, and is usually a plate-shaped structure with middle vertical ribs. The setting of the vertical ribs not only improves the structural strength of the mounting plate, but also can alleviate welding deformation.

[0003] See attached Figure 1 The raw material of the mounting plate is usually formed by integral extrusion. The vertical ribs are raised structures formed on the plate surface. The vertical ribs need to be processed during the production process of the mounting plate, and only the vertical ribs in the middle section are retained. The root of the vertical rib that needs to be processed fits the surface of the mounting plate. There is no way to design a die at this position. The conventional mold that relies on the interaction between the punch and the die for trimming cannot meet the processing requirements of this position. Therefore, for mounting plates with vertical ribs, the only way currently is to use CNC machine tools to mill off both sides of the vertical ribs. The above processing method has the following shortcomings:

[0004] 1. The processing efficiency of CNC machine tools is much lower than that of stamping. At the same time, the processing cost of CNC machine tools is much higher than that of stamping. The processing time of using CNC machine tools to process mounting plates is long, the production efficiency is low, and it cannot meet the production capacity requirements;

[0005] 2. Machining will produce a large amount of aluminum chips, which will affect the quality of subsequent processing, and will also increase the aluminum chip cleaning process, further increasing production costs.

[0006] Based on this, developing a die-free stamping die for processing anti-collision beam mounting plates and applying it to actual production is an urgent problem to be solved. Utility Model Content

[0007] The purpose of the utility model is to provide a non-die stamping die for processing an anti-collision beam mounting plate in order to solve the existing problems and solve the existing problems at the same time.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] A dieless stamping die for processing an anti-collision beam mounting plate includes a lower die base, a positioning support portion is arranged on the lower die base, and the positioning support portion is a supporting boss arranged in accordance with the shape of a vertical rib retention portion. The lower die base also includes a punch provided on the lower die base corresponding to the positioning support portion, and a shear notch is provided on the support portion of the punch corresponding to the positioning support portion.

[0010] Preferably, a positioning groove is provided on the positioning support portion, so that the mounting plate can fit tightly with the positioning support portion.

[0011] Preferably, a side top plate for pressing the end surface of the mounting plate is provided on the mold corresponding to the mounting plate.

[0012] Preferably, the side top plate is connected to a tightening cylinder, and the tightening cylinder is fixedly connected to the lower mold base, so that the side top plate is provided with a pressing force to fit the positioning support part through the tightening action of the cylinder.

[0013] Preferably, the mold is provided with a guide structure, which comprises a guide sleeve arranged on the lower mold base and a guide column arranged on the lower mold base, and the guide column is axially slidably matched with the guide sleeve.

[0014] Preferably, the punch and the positioning support are correspondingly configured with two sets so as to perform synchronous stamping and shearing on two mounting plates at the same time.

[0015] Preferably, the two sets of punches and the positioning support parts are arranged in a mirror image to optimize the stress of the structure.

[0016] Preferably, a lifting structure is provided on the mold to facilitate lifting and transporting the mold.

[0017] The beneficial effects of the utility model are:

[0018] The utility model realizes efficient stamping and shearing operations of the vertical ribs of the mounting plate by providing mutually cooperating punches and positioning support parts, thereby improving the problems of long processing time, low efficiency and high processing cost caused by using CNC machine tools to process this part. At the same time, this embodiment abandons the traditional processing idea of ​​setting concave and convex molds for the corresponding workpiece, and solves the problem that the root of the vertical rib fits with the bottom surface of the mounting plate and the concave mold cannot be designed. A positioning groove is provided on the positioning support part, so that the mounting plate can fit tightly with the positioning support part, forming a positioning effect on the mounting plate, improving the positioning accuracy and assembly stability of the mounting plate and the positioning support part, and ensuring the processing accuracy.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] like Figure 1-5 As shown, a dieless stamping die for processing an anti-collision beam mounting plate comprises a lower die base 1, on which a positioning support portion 2 is provided, and the positioning support portion 2 corresponds to a support boss 21 provided in accordance with the shape of a vertical rib retention portion. It also comprises an upper die base 3, on which a punch 4 is provided corresponding to the positioning support portion 2, and a shear notch 41 is provided at a support portion of the punch 4 corresponding to the positioning support portion 2.

[0028] When in use, the mounting plate to be processed is placed vertically on the positioning support part 2, and the vertical ribs of the mounting plate are supported on the support boss 21 of the positioning support part 2, and then the upper die seat 3 is pushed downward by the press to drive the punch 4 to perform stamping processing on the vertical ribs of the mounting plate. During the downward movement of the positioning support part 2, the positioning support part 2 receives the support of the support boss 21 of the positioning support part 2, and forms a shearing force on the vertical ribs of the mounting plate through the shearing notch 41 of the positioning support part 2. Finally, the shearing notch 41 moves to the bottom of the vertical ribs, retaining the middle vertical ribs of the mounting plate, and at the same time, the vertical ribs that need to be cut are sheared and removed, completing the vertical rib stamping operation of the mounting plate.

[0029] In this embodiment, the mutually coordinated convex mold 4 and the positioning support part 2 realize the efficient processing of the vertical ribs of the mounting plate, and improve the problems of long processing time, low efficiency and high processing cost caused by the CNC machine tool processing of this part. At the same time, this embodiment abandons the traditional processing idea of ​​setting a concave and convex mold for the corresponding workpiece, and solves the problem that the root of the vertical rib fits with the bottom surface of the mounting plate and the concave mold cannot be designed.

[0030] As a preferred embodiment, Figure 3 As shown, the positioning support part 2 is provided with a positioning groove 22, so that the mounting plate can be closely fitted with the positioning support part 2, thereby improving the positioning accuracy and assembly stability of the mounting plate and the positioning support part 2. The positioning groove 22 corresponds to the vertical rib of the mounting plate and is opened on the vertical surface of the positioning support part 2. When in use, one vertical rib of the mounting plate is supported on the supporting boss 21, and the other vertical rib lies in the positioning groove 22, and the end face of the mounting plate is kept closely fitted with the vertical surface of the positioning support part 2, forming a counterposition effect on the mounting plate, thereby ensuring the processing accuracy.

[0031] In a further embodiment, Figure 2 As shown, the mold is provided with a side top plate 5 corresponding to the mounting plate, which is used to press the end surface of the mounting plate so that the mounting plate fits tightly on the vertical surface of the positioning support part 2, further improving the processing stability.

[0032] Preferably, the side top plate 5 is connected to a tightening cylinder 6, and the tightening cylinder 6 is fixedly connected to the lower mold base 1, and the tightening action of the cylinder provides a pressing force for the side top plate 5 to fit the vertical surface of the positioning support part 2.

[0033] As a preferred embodiment, Figure 2 As shown, the mold is provided with a guide structure 7 to provide a guide for the punching action of the punch 4 and the positioning support part 2. The guide structure 7 includes a guide sleeve 71 provided on the upper die seat 3 and a guide column 72 provided on the lower die seat 1, and the guide column 72 is axially slidably matched with the guide sleeve 71. Through the guiding action of the guide sleeve 71 and the guide column 72, the action accuracy of the punch 4 and the positioning support part 2 is ensured, and the processing accuracy of the vertical ribs of the mounting plate is further improved.

[0034] As a preferred embodiment, two sets of the punch 4 and the positioning support part 2 are correspondingly configured, and two mounting plates can be punched and sheared simultaneously to improve processing efficiency.

[0035] More preferably, the two sets of punches 4 and the positioning support part 2 are arranged in a mirror image, so that the force on the mold structure is more reasonable, avoiding the mold from being skewed and affecting the processing quality.

[0036] Furthermore, a lifting structure 8 is provided on the mold to facilitate lifting and transporting the mold in cooperation with the lifting equipment.

[0037] The above disclosure is only a specific embodiment of the present patent, but the present patent is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, the deformation made should be deemed to belong to the protection of the present invention.
