Description

Technical Field

[0001] This utility model belongs to the technical field of pressure plate forming manufacturing process, specifically relating to a vehicle pressure plate direct pressing forming mold. Background Technology

[0002] The manufacturing process for the pressure plate forming of a certain type of vehicle requires three steps: shearing, punching (two punching operations using laser cutting), and forming. The existing forming process further includes two steps: first, pre-bending twice using a bending machine, and then manually rounding the plate. The existing forming process has a long processing cycle, low production efficiency, and makes it difficult to guarantee the arc accuracy of the pressure plate. Utility Model Content

[0003] (a) Technical problems to be solved This utility model proposes a direct pressing forming mold for vehicle pressure plates to solve the technical problem that it is difficult to guarantee the curvature and tolerance of the curved plate pressing arc.

[0004] (II) Technical Solution To solve the above-mentioned technical problems, this utility model proposes a vehicle plate direct pressing forming mold, which includes an upper mold and a lower mold. The upper mold includes a mold shank and a punch, and the lower mold includes a die, a lower template, a positioning pin, a retaining ring, and a positioning bend. The bottom of the mold shank is fixedly connected to the top of the punch, and the top of the mold shank is fixedly connected to the press slide, thus fixing the upper mold as a whole onto the press slide. The bottom of the lower template is fixedly connected to the worktable, and the bottom of the die is fixedly connected to the top of the lower template. The die is used to bear the pressure of the upper mold, preventing deformation of the sheet metal being pressed. The positioning pin is installed at the threaded hole on the front side of the lower template, serving as a positioning reference for positioning the sheet metal before pressing from the front. The retaining ring is fixed at the threaded hole on the side of the lower template. The vertical part of the L-shaped positioning bend is fixed between the lower template and the retaining ring via the retaining ring, and the horizontal part of the L-shaped positioning bend is used to position the sheet metal before pressing from the side. The positioning bend and the positioning pin together position the sheet metal before pressing in two directions.

[0005] Furthermore, the bottom of the die shank is fixedly connected to the top of the punch by multiple hexagonal head screws.

[0006] Furthermore, the bottom of the lower template is fixedly connected to the workbench with bolts.

[0007] Furthermore, the bottom of the die is fixedly connected to the top of the lower template by multiple hexagonal head screws.

[0008] Furthermore, two locating pins are installed at the threaded holes on the front side of the lower template.

[0009] Furthermore, the retaining ring is fixed to the side threaded hole of the lower template by an internal hexagonal head screw.

[0010] (III) Beneficial Effects This utility model proposes a direct pressing forming mold for vehicle pressure plates, including an upper mold and a lower mold. The upper mold includes a mold shank and a punch, while the lower mold includes a die, a lower template, a locating pin, a retaining ring, and a locating bend. The forming mold fully meets the requirements of the technical documents, ensuring good batch dimensional consistency. The upper and lower molds are easy to install and operate on the punch press, resulting in high production efficiency, convenient maintenance, and a neat and aesthetically pleasing appearance. The process saves 1 / 4 of the time, making it suitable for mass production with a short production cycle, high precision, and guaranteed compliance with drawing tolerances. The mold's upper and lower mold structures are rationally designed; the upper mold and lower mold compress the product, resulting in uniform force during forming. The lower mold has a large contact surface with the worktable, providing stable support. Using this utility model's mold for direct pressing on a punch press can meet the forming requirements of small-batch products at a low cost. Attached Figure Description

[0013] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0014] This embodiment proposes a vehicle pressure plate direct pressing forming mold, the overall structure of which is as follows: Figures 1-3 As shown, it mainly includes an upper mold and a lower mold. The upper mold includes a mold shank 1 and a punch 2, and the lower mold includes a die 3, a lower template 4, a locating pin 5, a retaining ring 6, and a locating bend 7.

[0015] The bottom of the die shank 1 is fixedly connected to the top of the punch 2 by multiple second internal hexagon socket head cap screws 9, and the top of the die shank 1 is fixedly connected to the punch press slide, thereby fixing the upper die as a whole on the punch press slide.

[0016] The bottom of the lower template 4 is fixedly connected to the worktable with bolts for easy forming operation. The bottom of the die 3 is fixedly connected to the top of the lower template 4 with multiple second internal hexagon head screws 9. The die 3 is used to bear the pressure of the upper mold, so that the sheet material being formed does not deform around its edges.

[0017] Two locating pins 5 are installed at the threaded holes on the front side of the lower template 4 as a positioning reference to position the sheet material before forming from the front side, so as to ensure the accuracy of the dimensions.

[0018] The retaining ring 6 is fixed to the side threaded hole of the lower template 4 by the first internal hexagon head screw 8. The vertical plate of the L-shaped positioning plate 7 is fixed between the lower template 4 and the retaining ring 6 by the retaining ring 6, and the horizontal plate of the L-shaped positioning plate 7 is used to position the sheet material before forming from the side. The retaining ring 6 prevents the positioning plate 7 from moving, ensuring the positioning dimension of the positioning plate 7 and avoiding affecting the dimensional accuracy. The positioning plate 7 and the positioning pin 5 can jointly position the sheet material before forming in two directions.

[0019] The working process of the above mold is as follows: the upper mold descends through the punch press slide and reaches the product workpiece sheet before forming, which is fixed by the positioning plate 7 and the positioning pin 5. The product is extruded and formed, completing the processing of one product. After manual adjustment, the product processing is completed, such as... Figure 4a and 4b As shown.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
