Description

Technical Field

[0001] The invention relates to the technical field of automobile moulds, and in particular to a common mould frame and an inclined wedge mechanism for trial-producing beam side shaping which can be reused. Background Art

[0002] In the automotive industry, the body beam is a key part of the body structure, and its structural strength and precision are crucial to the safety and performance of the car. In order to ensure the quality and precision of the beam, it is often necessary to perform complex shaping processes, including front shaping and side shaping.

[0003] In the traditional automobile beam shaping process, positive shaping and side shaping are two common processing methods. The positive shaping process is mainly used for materials with low tensile strength. Although this process has less rebound during the forming process and better forming effect, it still requires manual sheet metal adjustment to meet the quality standards required by customers. The side shaping process is suitable for high-strength materials and can shape both sides of the beam under a larger mold, making the beam more precise and stable. However, the production cost of the side shaping mold is high, and the weight of the mold is usually large, reaching 7 to 8 tons / set, which leads to increased manufacturing and transportation costs, and a long mold development cycle.

[0004] In addition, with the continuous development of the automobile industry, the market demand for small-batch customized production is getting higher and higher, and the traditional mold development model has gradually exposed many problems. Under the traditional model, the shaping process of each model beam requires the development of a separate mold, and the development process of each set of molds requires a lot of materials, casting and processing hours, resulting in a waste of mold development costs. At the same time, since many models have similar designs and sizes, using completely independent molds for production is not only inefficient, but also results in a large waste of resources in the manufacturing process.

[0005] In the current process of automobile mold development, the casting cost and processing cost of the mold still account for a large proportion, especially in the trial production stage. For beam parts of different models and specifications, the mold production and adjustment cycle is long, which seriously affects the production progress of the entire project. Since the assets of the mold usually belong to the OEM, the mold factory usually needs to design and manufacture molds that meet the requirements according to the project requirements of different OEMs. Therefore, the reuse rate of the mold is low, resulting in high mold costs and long-term waste of resources.

[0006] Therefore, how to reduce the development cost of molds, shorten the mold design and manufacturing cycle, and improve the utilization efficiency of molds through a new technical solution has become an urgent problem to be solved in the current field of automotive mold design. Summary of the invention

[0007] The purpose of the present invention is to design a reusable trial-produced common mold frame and inclined wedge mechanism for side shaping of beams, so as to provide an efficient, low-cost and flexible mold design scheme for small batch customized production.

[0008] The technical solution of the present invention is: to provide a common mold frame and a wedge mechanism for side shaping of a trial-produced beam that can be reused, the common mold frame and the wedge mechanism comprising three parts: a common lower mold base, a common upper mold base and a common side shaping wedge;

[0009] The common lower die base is a supporting frame of the die, and a plurality of functional components are arranged on the surface of the common lower die base, and the common lower die base includes a punch and a punch positioning key;

[0010] The punch is positioned and fixed to the common lower die base through a punch positioning key located on the common lower die base mounting surface, and then the punch is completely fixed to the common lower die base using bolts through screw holes on the common lower die base mounting surface to complete the installation;

[0011] The common upper die base is the part that applies pressure to the beam, and the common upper die base includes a pressing plate, a pressing plate nitrogen cylinder, a center guide block, a nitrogen cylinder bottom block, an inclined wedge guide plate, and an inclined wedge nitrogen cylinder assembly;

[0012] The nitrogen cylinder of the blank pressing plate and the nitrogen cylinder bottom block are located at the central axis of the common upper die seat mounting surface. The nitrogen cylinder of the blank pressing plate is used to apply downward pressure to the blank pressing plate during processing to complete the shaping of the side of the beam; the nitrogen cylinder bottom block is a raised flat plate structure, which limits the shortest distance between the blank pressing plate and the common upper die seat mounting surface to prevent the blank pressing plate from extruding the nitrogen cylinder of the blank pressing plate in the opposite direction and causing damage to the nitrogen cylinder of the blank pressing plate;

[0013] The center guide block, the angled wedge guide plate and the angled wedge nitrogen cylinder assembly are distributed on both sides of the central axis of the common upper die seat mounting surface. The center guide block and the angled wedge guide plate are used to guide the sliding of the common side full angle wedge. The center guide block plays a positioning role for the common side full angle wedge. The angled wedge nitrogen cylinder assembly is used to apply downward pressure to the common side full angle wedge during processing.

[0014] The common side beveling wedge is located between the common lower die seat and the common upper die seat, and is responsible for converting the vertical pressure into the lateral pressure at a specific angle, thereby completing the side shaping of the beam. The common side beveling wedge includes a knife block positioning key;

[0015] The knife block positioning key is located on the bottom surface of the common side bevel wedge and is used to position the side knife block. After positioning, the side knife block is completely fixed to the common side bevel wedge with bolts through several screw holes on the bottom surface of the common side bevel wedge to complete the installation.

[0016] According to the above structure, the common lower die base, the common upper die base and the common side bevel wedge are installed respectively. With the common lower die base as the bottom, the beam is placed in the common lower die base, and the common side bevel wedge is fixed to the bottom of the common upper die base, so that the common upper die base presses the beam downward to process it.

[0017] In any of the above technical solutions, further, the common lower die base also includes a clamping key; the punch is clamped by the clamping key located on the side of the common lower die base installation surface.

[0018] In any of the above technical solutions, further, the common lower die seat also includes: a side straightening and side guarding guide plate, an inclined wedge lower die guide plate, and an inclined wedge positioning guide plate;

[0019] The side guide plate for side adjustment, the bevel lower die guide plate and the bevel positioning guide plate are all located on the side of the common lower die seat mounting surface. The side guide plate for side adjustment and the bevel lower die guide plate are both raised flat plate structures. The bevel lower die guide plate is used to guide the sliding in of the common side adjustment bevel wedge during processing; the bevel positioning guide plate is a raised triangular ridge structure, which is used to position the sliding in of the common side adjustment bevel wedge; the side guide plate for side adjustment is used to prevent the tool block from lateral deformation during processing to ensure the consistency of the processing effect.

[0020] In any of the above technical solutions, further, the common upper die seat also includes: a pressure plate limiting plate and an inclined wedge limiting pressure plate;

[0021] The pressure plate limit plate and the inclined wedge limit pressure plate are located at the side edges of the common upper die seat installation surface. The pressure plate limit plate is located at the central axis position, and the inclined wedge limit pressure plate is located on both sides of the central axis. The pressure plate limit plate limits the pressure plate, and the inclined wedge limit pressure plate limits the common side whole inclined wedge, so that the two cannot move beyond a certain range on the common upper die seat.

[0022] In any of the above technical solutions, further, the common side bevel wedge also includes a bevel wedge guide plate; the bevel wedge guide plate is located on the side of the common side bevel wedge and is in sliding contact with the bevel wedge limiting pressure plate when sliding into the common upper die seat.

[0023] The beneficial effects of the present invention are:

[0024] The technical solution of the present invention adopts the design of common mold base and common wedge, so that the beam parts of different models can be processed under the same mold frame, thereby avoiding the high cost of developing independent molds for each model. This common design greatly reduces the development cost of the mold and saves casting and processing costs by reducing the separate purchase of parts.

[0025] Through modular design and standardized die base and wedge structure, the present invention significantly shortens the development cycle of the mold. The upper and lower die bases and wedge parts of the mold can be reused between different car models, thereby reducing the time and man-hours required for each mold development.

[0026] The mold design of the present invention fully considers the size and shape differences of different beam parts. By sharing the mold base and the shared wedge, it can meet the processing requirements of various types of beam parts, greatly improving the utilization rate of the mold. Especially for small batch customized production, this design can be reused between multiple projects, reducing the demand for mold resources for a single project, thereby achieving efficient utilization of the mold.

[0027] The structural design of the present invention ensures the stability and accuracy of each component, especially the installation and fixing method of the common wedge, which can ensure the uniform transmission of pressure and avoid deviation during the side shaping of the beam. In addition, the structures such as the punch positioning key and the pressure plate limit plate in the mold further ensure the stability of the beam parts during the processing, thereby improving the processing accuracy and consistency, and ensuring that the parts produced each time can meet the quality requirements.

[0028] The mold of the present invention has strong adaptability and can be quickly adjusted and switched according to the characteristics of the beam parts of different models. The design of the mold supports the switching of left and right parts at any time, avoiding the cumbersome process of remaking different molds in traditional molds. This flexibility is particularly suitable for the demand for small-batch customized production in the current market, which can better meet the personalized needs of customers and improve the flexibility and response speed of production.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0041] like Figure 3 As shown, the common lower die base 1 is equipped with multiple functional components for supporting the mold, including: a punch 4, a side guide plate 9, a clamping key 10, a punch positioning key 11, an inclined wedge lower die guide plate 12, and an inclined wedge positioning guide plate 13.

[0042] The punch 4 is positioned and fixed to the common lower die base 1 by the punch positioning key 11 located on the mounting surface of the common lower die base 1.

After positioning, the side knife block 6 is completely fixed to the common side bevel wedge 3 using bolts through several screw holes on the bottom surface of the common side bevel wedge 3 to complete the installation.

[0051] The knife block positioning key 20 is fixed in the Y direction, wherein the Y direction step distance is 105 mm, the X direction step distance is 180 mm, and the total length is 1500 mm, which can support the installation of the side whole knife block 6 with a maximum length of 1600 mm.
