[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The embodiment of the invention discloses a stamping die for automobile parts which is easy to clean.

[0026] According to the attached Figure 1-7 As shown, it includes a stamping die 1, which is composed of an upper die 11, a lower die 12 and a bottom plate 13. A linkage chip cleaning unit 2 is arranged inside the stamping die 1, and the linkage chip cleaning unit 2 includes a wire rope 21 and a push plate 23; The steel wire rope 21 is arranged at both ends of the punching die 1, and the upper die 11 pulls the push plate 23 through the steel wire rope 21, so that it is slidably connected with the bottom plate 13; The end of the push plate 23 is in sliding contact with the inner bottom of the bottom plate 13 , and the push plate 23 is driven by the steel wire rope 21 to actively slide and push out the debris inside the bottom plate 13 .

[0027] The upper mold 11 includes an upper base plate 111, a lower base plate 112 and a limiting groove 113; the lower base plate 112 is arranged below the upper base plate 111, and the limiting groove 113 is opened inside the upper base plate 111. The upper mold 11 also includes a limiting block 114 and a support rod 115; the limiting block 114 is slidably connected to the inside of the limiting groove 113, and the end of the limiting block 114 is against the inner wall of the limiting groove 113, and the end of the support rod 115 is fixedly connected to the limiting block 114, and the other end of the support rod 115 is fixedly connected to the lower base plate 112. The upper bottom plate 111 further comprises a punching member 116, a groove member 117 and a bending member 118; the punching member 116 is fixedly connected to one side of the bottom of the upper bottom plate 111, the bending member 118 is fixedly connected to the other side of the bottom of the upper bottom plate 111, the groove member 117 is arranged between the punching member 116 and the bending member 118, the groove member 117 is fixedly connected to the upper bottom plate 111, and a shock absorbing member 14 is arranged between the upper bottom plate 111 and the lower bottom plate 112, and the shock absorbing member 14 comprises a pillar 141, a first spring 142 and a positioning hole 143; the pillar 141 is fixedly connected to the upper bottom plate 111. Inside the bottom plate 111, the first spring 142 is wound on the outer surface of the support 141, the end of the first spring 142 is fixedly connected to the support 141, and the other end of the first spring 142 is against the lower bottom plate 112. The positioning hole 143 is opened inside the lower bottom plate 112, and the support 141 is slidably connected inside the lower bottom plate 112. The lower mold 12 and the base 13 are also directly provided with a shock absorbing member 14, which is used to reduce the direct impact of the lower mold 12 and the base 13, ensure the self-strength of the two, and improve the lower mold 12 and the base 13. The service life of the pressing die is extended in disguise, and the user's needs are met. When the punching member 116 is pushed downward by the hydraulic rod, it passes through the lower bottom plate 112 and contacts the raw material steel plate. Since the punching groove 121 is deep, the punching member 116 can easily punch through the raw material steel plate, so that the raw material debris falls into the inside of the bottom plate 13. When the groove making member 117 is downward, since the groove 122 is shallow, the groove making member 117 will only make grooves inside the raw material steel plate, and will not directly punch through the raw material steel plate, thereby ensuring the practicality of the device. One side of the bottom of the bending member 118 is an arc-shaped structure, which cooperates with the arc-shaped side wall of the bending groove 123, so that one side of the raw steel plate is bent. By adjusting the size of the bending member 118 and the angle of the arc-shaped side wall of the bending groove 123, the side wall of the raw steel plate can be bent at any angle; It has practical value and meets the needs of users. How does the first spring 142 achieve the shock-absorbing effect? ​​The hydraulic press pushes the upper base plate 111 downward, and the base plate 13 pushes the support 141 toward the inside of the positioning hole 143. The first spring 142 is tightened. At this time, the existence of the first spring 142 prevents the upper mold 11 from directly and rigidly contacting the lower mold 12, thereby reducing the impact of the two on each other, protecting the upper mold 11 and the lower mold 12, and meeting the needs of users.

[0028] The lower mold 12 includes a punching groove 121, a groove 122 and a bending groove 123; the punching groove 121 is opened on one side of the lower mold 12, the bending groove 123 is opened on the other side of the lower mold 12, and the groove 122 is opened between the punching groove 121 and the bending groove 123. The four sides of the top of the bottom plate 13 are fixedly connected with shock-absorbing columns 15, and the shock-absorbing columns 15 are movably connected to the upper mold 11. The shock-absorbing columns 15 are fixedly connected to the four sides of the bottom plate 13, and its components are positioning columns for auxiliary positioning, auxiliary shock-absorbing springs wound on the outer surface of the positioning columns, and sleeves sleeved on the end of the positioning columns. The sleeves are fixedly connected to the auxiliary shock-absorbing springs. The four sides of the upper bottom plate 111 are provided with positioning grooves. The internal fixed connection limit ring has the following usage process: the hydraulic rod pushes the upper mold 11 to move downward, the sleeve is movably connected to the inside of the positioning groove, and the end of the sleeve is against the limit ring. At this time, the hydraulic rod continues to push the upper mold 11 downward, so that the sleeve also moves downward, causing the auxiliary shock-absorbing spring to be tightened, which achieves the purpose of shock absorption, reduces the direct collision between the upper mold 11 and the lower mold 12, reduces the impact of the two on each other, extends the service life of the stamping mold 1, and ensures the normal use of the device. After the stamping is completed, the hydraulic rod pushes the upper mold 11 to move upward, and under the reaction force of the auxiliary shock-absorbing spring, the sleeve also moves upward until it returns to its original position to meet the needs of users.

[0029] Fixed columns 24 are fixedly connected to both sides of the top of the bottom plate 13, guide wheels 25 are set at both ends of the fixed columns 24, the wire rope 21 is set inside the fixed columns 24 and the guide wheels 25, the bottom plate 13 is slidably connected to the inside of the first slider 26, the first slider 26 is rotatably connected to the inside of the rotating rod 22, the first slider 26 is fixedly connected to both sides of the second spring 27, the end of the second spring 27 is against the inner wall of the bottom plate 13, the bottom plate 13 is slidably connected to the inside of the second slider 29, the rotating rod 22 is rotatably connected to the second slider 29. In summary, compared with the prior art, the device has the following beneficial effects: when the device is used, the raw steel plate is placed on the top of the lower mold 12, the hydraulic rod pushes the upper mold 11 to move downward, the lower bottom plate 112 first contacts the raw steel plate, the hydraulic rod pushes the upper bottom plate 111 to continue to move downward, the upper bottom plate 111 pushes the support 141 to the inside of the positioning hole 143, the first spring 142 is tightened, at this time the punching member 116, the groove making member 117 and the bending member 118 contact the raw steel plate, respectively The raw steel plate is punched, grooved and bent. When the upper mold 11 is downward, the upper mold 11 pulls the wire rope 21 downward. The wire rope 21 is guided by the fixed column 24 and the guide wheel 25 to pull the first slider 26 to slide to both sides. At this time, the second spring 27 is tightened, and the first slider 26 pulls the rotating rod 22, so that the push plate 23 and the movable bar 28 slide to one side. At this time, the debris punched from the raw steel plate by the punching member 116 falls into the bottom plate 13. After the punching, groove making and bending are completed, the hydraulic rod pushes the upper bottom plate 11 1 is upward, the first spring 142 pulls the support 141 out of the interior of the positioning hole 143, and at the same time, the support rod 115 is abutted against the limiting groove 113 through the limiting block 114, ensuring that the lower bottom plate 112 will not slide out of the interior of the upper bottom plate 111. At the same time, the upper mold 11 is upward, so that the wire rope 21 is loosened and the traction force from the wire rope 21 is lost. Under the reaction force of the second spring 27, the first slider 26 slides in the direction of the central axis, pushing the rotating rod 22 to rotate, and pushing the push plate 23 to one side. At this time, since the end of the push plate 23 is against the bottom of the bottom plate 13, the debris is pushed by the push plate 23 and slides to one side until it is pushed out of the inside of the bottom plate 13, completing the automatic cleaning of the debris. The device can realize automatic cleaning of the debris inside the stamping die 1 without using extra power sources, effectively utilizing a single power source, and converting the vertical force into a lateral force through the wire rope 21 and the rotating rod 22, which has practical value, realizes the efficient application of a single power source, and meets the needs of users.
