Description

Technical Field

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

[0002] In the automotive industry, stamping is a crucial step in the manufacturing of automotive parts, accounting for a significant proportion of the total weight of raw materials. For example, body frame parts and body panels are often stamped from stainless steel blocks or sheets. Specialized steel for the automotive body is characterized by its resistance to cracking during deep drawing. Galvanized stainless steel blanks are used in areas requiring rust prevention, such as fenders and roof panels. High-strength stainless steel blanks are used in areas subjected to high stress, such as radiator support components and crossbeams.

[0003] Currently, various stamping equipment is typically used to stamp stainless steel automotive parts. However, the limiting devices in some stamping equipment are too simple in structure, making it difficult to flexibly and accurately limit stamping parts of different shapes and sizes. This causes the stamping parts to easily shift during the stamping process, resulting in stamping deviations and low product qualification rates. Utility Model Content

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the bottom of the slide rod is provided with a support platform, and the support platform is provided with two sets of first electric actuators, the output end of the first electric actuators being connected to the second connecting block.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the slide rod is provided with a slide rail, and the slide cylinder is slidably connected to the slide rail.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting component includes a limiting block, which is slidably connected to the top of the stamping table; the front end of the limiting block is provided with an arc-shaped limiting plate; a second electric push rod is provided inside the limiting block, and the output end of the second electric push rod is provided with a conical fixing block.

[0010] The beneficial effects of this utility model are as follows: In this device, through the setting of the linkage structure and the limiting component, the first electric push rod drives the swing arm to move. Under the coordinated action of the slide cylinder, slide rod, first connecting rod, first connecting block and second support, when the two sets of swing arms swing outward, they can drive the two sets of limiting components to move closer to each other and clamp the stamping part; and the limiting component can clamp and limit stamping parts of different sizes and shapes.

[0012] Figure 2 This is a schematic diagram of the limiting component in this utility model. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0014] See attached diagram. Figures 1 to 2 In this embodiment, a stamping device for automotive stamping parts includes a stamping table 1, a frame 2 on one side of the top of the stamping table 1, a stamping cylinder 20 on the frame 2, and a stamping head 21 at the output end of the stamping cylinder 20; a limiting device is provided inside the stamping table 1; and a limiting component is provided at the output end of the limiting device.

[0015] Furthermore, the limiting device includes a slide rod 3 installed on the inner top wall of the stamping table 1, a slide cylinder 4 installed on the outer periphery of the slide rod 3, and a connecting rod structure on both sides of the slide cylinder 4. The connecting rod structure includes a first support 40 set on the outer wall of the slide cylinder 4, a first connecting rod 41 hinged on the first support 40, a swing rod 5 hinged to one end of the first connecting rod 41, a first connecting block 50 hinged to the top of the swing rod 5, and a second connecting block 51 hinged to its bottom; one end of the first connecting block 50 is hinged to the limiting component; a second support 7 is provided on the side of the stamping table 1 near the first connecting block 50, and the second support 7 is hinged to the swing rod 5.

[0016] Furthermore, the bottom of the slide bar 3 is provided with a support platform 6, and the support platform 6 is provided with two sets of first electric push rods 60. The output end of the first electric push rod 60 is connected to the second connecting block 51.

[0017] Furthermore, the slide rod 3 is equipped with a slide rail, and the slide cylinder 4 is slidably connected to the slide rail.

[0018] Furthermore, the limiting component includes a limiting block 8, with an arc-shaped limiting plate 80 at the front end of the limiting block 8; a second electric push rod 9 is provided inside the limiting block 8, and a conical fixing block 90 is provided at the output end of the second electric push rod 9.

[0019] The working principle of this device is as follows: The first electric push rod 60 pushes the second connecting block 51 to move outward, thereby causing the swing rod 5 to swing outward. At the same time as the swing rod 5 swings outward, the slide cylinder 4 moves downward on the slide rod 3, thereby causing the first connecting rod 41 to also extend outward. The swing amplitude of the swing rod 5 is adjusted by the slide cylinder 4, the slide rod 3 and the second support 7. At the same time, the limiting component on one side of the top of the swing rod 5 moves closer to the stamping part on the stamping table 1, and the arc-shaped limiting plate 80 can limit the stamping part. In order to further fix stamping parts of different shapes, the second electric push rod 9 drives the conical fixing block 90 to extend towards the arc-shaped limiting plate 80, which can abut against the outer wall of the irregular stamping part, thereby achieving clamping and fixing.

[0020] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
