[0027] Such as Figures 1 to 6As shown in the figure, a stamping die for automotive parts includes: a downward pressing component 1 for stamping metal parts, a moving component 3 for moving the stamping position of the metal parts, and a pressure relief component 4 for relieving pressure at the bottom of the metal parts.

[0028] The downward pressing component 1 includes a first cylinder 11, a clamping component 12, a stamping component 13, and a bolt 14; the first cylinder 11 is fixedly connected to the clamping component 12, the clamping component 12 is clamped and connected to the stamping component 13, and the stamping component 13 is threadedly connected to the bolt 14; when it is necessary to stamp automotive parts, the first cylinder 11 is started, so that the output end of the first cylinder 11 outputs downward, driving the clamping component 12 and the stamping component 13 to move downward, so that the stamping component 13 stamps the parts at its bottom. At the same time, by rotating the bolt 14, the restriction between the clamping component 12 and the stamping component 13 can be released, which is convenient for replacing the stamping component 13, so that different stamping components 13 can be replaced to maintain the stamping component 13.

[0029] The moving component 3 is composed of a second cylinder 31, a forming table 32, and a clamping plate 33; the second cylinder 31 is fixedly connected to the clamping plate 33, the clamping plate 33 is fixedly connected to the forming table 32, and the forming table 32 is divided into two groups; by driving the clamping plate 33 to move through the second cylinder 31, the stamping component 13 can stamp one of the forming tables 32, which is convenient for the forming of automotive parts;

[0030] As common knowledge: when the material is very thin and the sum of the weight of the waste chips themselves and the friction force of the die edge on them is less than the adsorption force of the punch on them, during the upward movement of the punch, the waste chips are adsorbed on the surface of the punch and rise accordingly, thus forming chip jumping.

[0031] As a supplement: grooves are provided on the forming table 32, and chamfers with a size of 0.3 mm are provided at the corners of the forming table 32, so as to prevent the waste chips from rising with the stamping component 13 and jumping out of the forming table 32. At the same time, side edges are provided on the forming table 32, which can complicate the shape of the waste chips to increase the clamping force of the waste chips in the die, thus preventing chip jumping.

[0032] The pressure relief component 4 is composed of a rotating motor 41, a bidirectional screw 42, a blower 43, an air pump 44, a connecting pipe 45, and an air suction pipe 46; the rotating motor 41 is fixedly connected to the bidirectional screw 42, two groups of opposite threads are provided on the bidirectional screw 42, the center of the bidirectional screw 42 is fixedly connected to the blower 43, the blower 43 is fixedly connected to the air pump 44, the bidirectional screw 42 is rotatably connected to the connecting pipe 45, and the connecting pipe 45 is fixedly connected to the air suction pipe 46; a first engaging circular plate 421 and a second engaging circular plate 422 are respectively installed at two groups of reverse threads of the bidirectional screw 42, and the bidirectional screw 42 is hollow and penetrates through the connecting pipe 45; by starting the rotating motor 41, the bidirectional screw 42 rotates, driving the first engaging circular plate 421 and the second engaging circular plate 422 on the left and right sides of the bidirectional screw 42 to move towards the center of the bidirectional screw 42 at the same time, so that the connecting pipes 45 on the left and right sides move towards the center at the same time, so that the two air suction pipes 46 are simultaneously attached to the left and right sides of the forming table 32, fixing the forming table 32 and sucking air from its bottom at the same time, making the bottom of the forming table 32 in a negative pressure state, sucking away waste chips, so as to prevent waste chips from jumping.

[0033] An installation box 2 is installed at the bottom of the first cylinder 11, and through holes are provided on the surface of the installation box 2; by wrapping the forming table 32 with the installation box 2, the internal gas can be better exported, and it is easier to form a negative pressure state.

[0034] Working principle:

[0035] When it is necessary to stamp automobile parts, start the first cylinder 11 to drive the engaging part 12 and the stamping part 13 to move downward, so that the stamping part 13 stamps the parts at its bottom. Drive the engaging plate 33 to move through the second cylinder 31, so that the stamping part 13 can stamp one of the forming tables 32, which is convenient for the forming of automobile parts. By starting the rotating motor 41, the bidirectional screw 42 rotates, driving the first engaging circular plate 421 and the second engaging circular plate 422 on the left and right sides of the bidirectional screw 42 to rotate and move towards the center of the bidirectional screw 42 at the same time, so that the connecting pipes 45 on the left and right sides move towards the center at the same time, so that the two air suction pipes 46 are simultaneously attached to the left and right sides of the forming table 32, sucking air from the bottom of the forming table 32, making the bottom of the forming table 32 in a negative pressure state, sucking away waste chips, so as to better prevent the occurrence of chip jumping.
