DETAILED DESCRIPTION

[0029] The continuous stamping die of the automobile ball head plug consists of a forming die 1 and a stamping die 2 arranged above the forming die, so that the steel strip raw material is squeezed, deformed and cut on the forming die by the stamping die 2 to make the automobile ball head plug.

[0030] The forming die 1 is provided with a limit groove forming groove 101 in a staggered manner, so that the steel strip raw material is deformed downward by the limit groove forming groove 101, thereby forming a limit groove. The forming die 1 at the front end of the limit groove forming groove 101 is provided with a stamping forming hole 102 in a staggered manner, so that the automobile ball head plug cover after the limit groove is formed is cut off from the steel strip raw material by the stamping forming hole 102, so that the automobile ball head plug cover is separated from the steel strip raw material. Floating limiters for limiting the raw material steel strip are respectively provided on both sides of the top end surface of the forming die 1, so that the steel strip raw material is limited by the floating limiter, thereby preventing the steel strip raw material from deviating during movement, avoiding overlapping of stamping areas, ensuring accurate stamping, and ensuring product quality.

[0031] The stamping die 2 is composed of a connector 201, a support plate 202 and a pressing plate 203 arranged in sequence from top to bottom. A limit slot punch 204 is staggered and inserted on the pressing plate 203, so that the limit slot punch 204 can punch downward, and the limit slot punch 204 cooperates with the limit slot forming groove 101 to squeeze and deform the steel strip raw material to form a limit slot on the steel strip raw material. A forming punch 205 is staggered and inserted on the pressing plate 203 at the front end of the limit slot punch 204, so that the forming punch 205 can punch downward, and the forming punch 205 cooperates with the stamping forming hole 102 to cut off the steel around the limit slot and the steel strip raw material to form a car ball head plug. The forming punch 205 and the limit slot punch 204 are respectively passed through the support plate 202 and fixedly connected to the connector 201. The function of the connector 201 is to connect the punch press, so that the punch press can drive the limit slot punch 204 and the forming punch 205 to move downward through the connector 201, so as to punch downward through the limit slot punch 204 and the forming punch 205 moving downward. The function of the pressing plate 203 is to clamp the steel strip raw material through the pressing plate 203 and the forming die 1, so that the steel strip raw material is not easy to move during the punching process, thereby ensuring accurate punching. Since the limit slot punch 204 and the forming punch 205, as well as the limit slot forming groove 101 and the punching forming hole 102 are respectively staggered, the punching area can be staggered on the steel strip raw material during the punching process, thereby continuously punching the steel strip raw material during the forward conveying of the steel strip raw material, further improving production efficiency.

[0032] Positioning punching holes 103 are respectively provided on both sides of the top end surface of the forming die 1 at the rear end of the limiting groove forming groove 101, and a plurality of positioning holes 104 are respectively provided on both sides of the top end surface of the forming die 1 at the front end of the positioning punching hole 103. Positioning punch rods 206 are respectively inserted on both sides of the pressure plate 203 at the rear end of the limiting groove punch 204, and the positioning punch rod 206 passes through the support plate 202 and is fixedly connected to the connector 201; a plurality of positioning heads 207 are respectively provided on both sides of the bottom end surface of the pressure plate 203 at the front end of the positioning punch rod 206. The function of the positioning punch rod 206 is to punch a through hole on the raw material of the steel strip through the cooperation of the positioning punch rod 206 and the positioning punching hole 103. The function of the positioning head 207 is to further limit the raw material of the steel strip by inserting the positioning head 207 into the through hole and the positioning hole 104 formed by punching in sequence, so as to prevent the raw material of the steel strip from shifting during the punching process, ensure the accuracy of the punching, and thus ensure the quality of the product.

[0033] The support plate 202 outside the positioning punch 206, the limiting groove punch 204 and the forming punch 205 is respectively provided with an upper limit ring groove 208; the positioning punch 206, the limiting groove punch 204 and the forming punch 205 are respectively provided with a support flange 209, and the support flange 209 is slidably connected with the upper limit ring groove 208. The function of the support flange 209 is to support the support plate 202 and the pressing plate 203 through the support flange 208 to prevent the support plate 202 and the pressing plate 203 from being separated from the limiting groove punch 204 and the forming punch 205; at the same time, the positioning punch 206, the limiting groove punch 204 and the forming punch 205 are limited by the support flange 209, so as to prevent excessive stamping, thereby ensuring the quality of the finished product. The limiting groove punch 204 and the forming punch 205 between the support plate 202 and the connecting head 201 are respectively provided with demolding springs 210, so that the pressing plate 203 is pushed downward by the elastic force of the demolding springs 210 and the gravity of the support plate 202 and the pressing plate 203 themselves, so that the stamped steel strip raw material is withdrawn by the positioning punch 206, the limiting groove punch 204 and the forming punch 205, so that the positioning punch 206, the limiting groove punch 204 and the forming punch 205 are separated from the steel strip raw material.

[0034] The end of the forming die 1 at the front end of the punching forming hole 102 is provided with a shearing groove 105. A shearing block 211 is provided on the connecting head 201 at the front end of the forming punch 205, and the bottom end surface of the shearing block 211 passes through the support plate 202 and is flush with the bottom end surface of the pressing plate 203. The function of the shearing block 211 is to cut the waste remaining after the steel strip raw material is stamped through the shearing block 211 and the shearing groove 105, and cut the waste into small pieces, thereby facilitating the storage and transportation of the waste.

[0035] The floating limiter is composed of a floating pin 106, a limit rod 107 and a return spring 108. A limit flange 109 is arranged on the floating pin 106. The end of the floating pin 106 above the limit flange 109 is movably mounted with the limit rod 107 through a bearing, and the top end of the limit rod 107 extends to the top of the forming die 1; the floating pin 106 below the limit flange 109 is provided with a return spring 108. The function of the limit rod 107 is to limit the steel strip raw material through the limit rod 107, so that the steel strip raw material can only move between the limit rods 107, thereby ensuring that the steel strip raw material is not easy to deviate when the steel strip raw material is conveyed forward, thereby ensuring the accurate stamping position. The function of the floating pin 106 is to enable the limit rod 107 to float up and down through the floating pin 106, thereby preventing the limit rod 107 from abutting against the pressing plate 203, thereby ensuring that the limit rod 107 does not affect the stamping in the process of limiting the steel strip raw material. The function of the reset spring 108 is to push the floating pin 106 to reset upwards through the reset spring 108, and then push the limit rod 107 to reset upwards, ensuring that the limit rod 107 can limit the steel strip raw material after stamping. Since the limit rod 107 is connected to the floating pin 106 through a bearing, the limit rod 107 can rotate, and then when the steel strip raw material is conveyed forward, there is rolling friction between the limit rod 107 and the steel strip raw material, which effectively reduces the wear on the limit rod 107.

[0036] The forming die 1 is provided with a spring assembly hole 110, and a supporting flange 111 is provided on the inner wall of the spring assembly hole 110, and the supporting flange 111 is abutted against the bottom end of the return spring 108; a lower limiting ring groove 112 is provided on the forming die 1 above the spring assembly hole 110, and the lower limiting ring groove 112 is slidably connected with the limiting flange 109. The function of the lower limiting ring groove 112 is to limit the supporting flange 111 through the lower limiting ring groove 112, thereby limiting the floating of the floating pin 106, thereby limiting the floating of the limiting rod 107.

[0037] A limiting groove 113 is provided on the circumference of the end of the limiting rod 107 above the forming die 1, so as to be connected to the steel strip raw material through the limiting groove 113. On the one hand, the steel strip raw material is limited by the limiting groove 113; on the other hand, when the limiting rod 107 floats upward, the limiting groove 113 drives the steel strip raw material to float upward, so that the steel strip raw material is demolded from the forming die 1, thereby avoiding affecting the forward conveyance of the steel strip raw material.

[0038] A plurality of limiting countersunk holes 212 are respectively arranged on both sides of the bottom end surface of the pressing plate 203 so as to avoid the top end of the limiting rod 107 through the limiting countersunk holes 212 so that the limiting rod 107 is not easily affected by the stamping.

[0039] When the continuous stamping die of the automobile ball head plug cover is working, the steel strip raw material is conveyed forward step by step. After the steel strip raw material is conveyed to the right place and stops, the stamping machine drives the stamping die 2 to move downward. When the stamping die 2 moves downward, the pressing plate 203 first contacts the steel strip raw material. When the pressing plate 203 continues to move downward, the pressing plate 203 pushes the steel strip raw material downward until the bottom end surface of the steel strip raw material abuts against the forming die 1, and the steel strip raw material is clamped and fixed between the pressing plate 203 and the forming die 1. After the pressing plate 203 cooperates with the forming die 1 to clamp the steel strip raw material, the pressing plate 203 and the supporting plate 202 cannot continue to move downward. During the process of the connecting head 201 continuing to move downward, the connecting head 201 pushes the positioning punch 206, the limiting groove punch 204 and the forming punch 205 to continue to move downward. The positioning punch 206 cooperates with the positioning punching hole 103 to punch the steel plate raw material to form a through hole that limits the steel plate raw material; the limiting groove punch 204 cooperates with the limiting groove forming groove 101 to punch the steel plate raw material to form a limiting groove; the forming punch 205 cooperates with the punching forming hole 102 to cut the steel plate raw material to form a product. After the punching is completed, the punching machine drives the punching die 2 upward. During the upward process of the punching die 2, the punching die 2 is separated from the steel strip raw material under the action of the demoulding spring 210. During the separation process of the punching die 2 from the steel strip raw material, under the action of the reset spring 108, the limiting rod 107 drives the steel strip raw material upward through the limiting groove 113, so that the steel strip raw material is separated from the forming die 1. After the steel strip raw material is separated from the forming die 1 and the stamping die respectively, it enters the next working cycle.

[0040] The continuous stamping die of the automobile ball head plug cover can punch the limit groove through the limit groove forming groove in cooperation with the limit groove punch, and can punch and form through the punching forming hole in cooperation with the forming punch. It can complete multiple stamping processes within one stamping stroke, which can effectively improve production efficiency. It can perform continuous stamping during the forward movement of the steel strip raw material, which can further improve production efficiency. The position of the steel strip raw material can be limited by the floating limiter, so that the steel strip raw material is not easy to deviate during the continuous stamping process, ensuring accurate stamping positioning, and then ensuring that the stamping area is not easy to overlap, ensuring product quality. It solves the problem that the existing mold cannot be stamped continuously, resulting in low production efficiency.
