Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a stamping die for automotive parts. Background Technology

[0002] Automotive parts stamping dies are tools or equipment used to manufacture automotive parts. Stamping is a metal processing technique that typically involves placing sheet metal in a die and then applying pressure to deform or cut it into the desired shape.

[0003] When stamping automotive parts, the coiled material needs to be stretched and flattened before being fed into the stamping press for shaping. However, if the coiled parts are not completely flattened or spring back, the unevenness of the part surface may increase the friction with the mold surface, making it difficult for the parts to pass through the mold smoothly and causing jamming. Utility Model Content

[0004] The purpose of this utility model is to provide a stamping die for automotive parts, addressing the shortcomings and deficiencies of existing technologies.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stamping die for automotive parts, including a worktable, the innovation of which lies in: the left and right sides of the worktable are divided into a stamping base plate and a conveying base plate, and the conveying base plate is lower than the stamping base plate; a pair of L-shaped strip clamps are provided on the stamping base plate, and a limiting and flattening groove is formed between the strip clamps and the stamping base plate; an installation groove is opened inside the conveying base plate, and multiple conveying rollers are arranged inside the installation groove, the conveying rollers being flush with the surface of the stamping base plate; multiple support columns are provided on the stamping base plate, and a common crossbeam is provided at the top of the support columns, and a stamping cylinder and a pressing cylinder are respectively arranged on the crossbeam, the stamping cylinder being located above the stamping base plate, a stamping plate being provided at the end of the piston rod of the stamping cylinder, and multiple stamping heads being provided below the stamping plate, with multiple stamping holes opened at corresponding positions on the stamping base plate; a pressing plate is provided at the end of the piston rod of the pressing cylinder, and an installation groove is also opened at the bottom of the pressing plate, and multiple conveying rollers are arranged in the installation groove; a pushing mechanism is provided on the front and rear sides of the worktable.

[0006] Furthermore, multiple guide posts are respectively provided on the top of the stamping plate and the lower pressure plate, and the guide posts are arranged through the crossbeam.

[0007] Furthermore, a rubber conveyor belt is wrapped around the outside of the conveyor roller.

[0008] Furthermore, the pushing mechanism includes a pair of telescopic cylinders, which are located on the front and rear sides of the worktable respectively. A pushing plate is provided between the piston rod ends of the telescopic cylinders, and the pushing plate is located between the upper and lower conveying rollers.

[0009] The beneficial effects of this utility model after adopting the above structure are as follows:

[0010] This utility model uses a flattening mechanism to flatten the roll material before conveying it to a stamping mechanism for stamping. The flattened sheet material is limited by a limiting and flattening groove formed by a strip clamp and a stamping base plate, thereby preventing the sheet material from bending and increasing the friction between the parts and the mold surface, which would make it difficult for the parts to pass through the mold smoothly and avoid jamming.

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

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0017] See Figure 1-2A stamping die for automotive parts includes a worktable, with a stamping base plate 1 and a conveying base plate 2 on the left and right sides, respectively, the conveying base plate 2 being lower than the stamping base plate 1; a pair of L-shaped strip clamps 3 are provided on the stamping base plate 1, and a limiting and leveling groove 4 is formed between the strip clamps 3 and the stamping base plate 1; an installation groove is formed inside the conveying base plate 2, and multiple conveying rollers 5 are provided inside the installation groove, the conveying rollers 5 being flush with the surface of the stamping base plate 1; multiple support columns 6 are provided on the stamping base plate 1, the top of the support columns 6 being... The worktable is equipped with a single crossbeam 7, on which a stamping cylinder 8 and a pressing cylinder 9 are respectively mounted. The stamping cylinder 8 is located above the stamping base plate 1. A stamping plate 10 is mounted at the end of the piston rod of the stamping cylinder 8. Multiple stamping heads 11 are mounted below the stamping plate 10. Multiple stamping holes 12 are opened at the corresponding positions on the stamping base plate 1. A pressing plate 13 is mounted at the end of the piston rod of the pressing cylinder 9. A mounting groove is also opened at the bottom of the pressing plate 13, and multiple conveying rollers 5 are mounted in the mounting groove. A pushing mechanism 14 is mounted on the front and rear sides of the worktable. Specifically, the sheet metal is placed on the conveyor roller 5, the pressing cylinder 9 is activated, the pressing plate 13 moves down, and the sheet metal is leveled by the conveyor rollers 5 at both ends. Then, the sheet metal is slowly conveyed to the stamping base plate 1 by the pushing mechanism 14, specifically into the limiting flat groove 4, so that the sheet metal is still in a flat state. Then, the stamping cylinder 8 is activated, the punch 11 presses down, and cooperates with the stamping hole 12 to complete the stamping operation of the parts. After stamping, the parts are removed from the punching hole 12, and the waste sheet metal is moved out from the front and back sides of the limiting flat groove 4 (that is, the front and back sides of the worktable). The height of the limiting flat groove 4 is matched with the thickness of the sheet metal to ensure that the sheet metal is in a flat state in the limiting flat groove 4.

[0018] In this embodiment, multiple guide posts 15 are respectively provided on the top of the stamping plate 10 and the lower pressure plate 13, and the guide posts 15 are disposed through the crossbeam 7. The guide posts 15 can improve the stability of the stamping plate 10 and the lower pressure plate 13 in vertical movement, thereby facilitating stamping and leveling.

[0019] In this embodiment, a rubber conveyor belt 16 is wrapped around the outside of the conveyor roller 5. The rubber conveyor belt 16 can prevent damage to the sheet material and also facilitates conveying.

[0020] In this embodiment, the pushing mechanism 14 includes a pair of telescopic cylinders 141, located on the front and rear sides of the worktable respectively. A pushing plate 142 is disposed between the piston rod ends of the telescopic cylinders 141, and the pushing plate 142 is located between the upper and lower conveying rollers. The initial state of the telescopic cylinders 141 is that the piston rod is in the extended state. When it is necessary to convey the sheet material to the limiting flattening groove 4, the telescopic cylinders 141 reset, the piston rod slowly retracts, and the pushing plate 142 abuts against the side thickness of the sheet material, pushing the sheet material into the limiting flattening groove 4 through the pushing plate 142.

[0021] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
