Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a stamping mold for a front cross beam tube of an automobile. Background Art

[0002] As a safety part in the car, the strength of the front cross beam tube of the car is related to the collision performance of the vehicle. Therefore, most of the current front cross beam tubes of the car are made by one-piece stamping. The front cross beam tube of the car made by stamping has higher strength than that made by welding and other means. The stamping of the front cross beam tube of the car requires a forming mold. After the existing stamping forming mold is used to press the front cross beam tube of the car, it is usually necessary to manually reach into the space between the two molds to take the material (between the upper and lower mold groups). However, after long-term use, the upper mold group of most molds is prone to fall off at the connection part with the press. If the upper mold group falls off when the worker takes the material, it is easy for the mold to hurt people. For this reason, the utility model improves a stamping mold that can save manual material taking. Summary of the invention

[0003] The disclosed embodiment relates to a stamping die for a front cross beam tube of an automobile. When the upper die is restored after stamping and forming the cross beam tube workpiece, the push rod will automatically move forward with the push piece, and push the stamped front cross beam tube of the automobile into the interior of a collection box, thereby realizing automatic material retrieval.

[0036] By placing the beam tube workpiece 103 on the lower die 102, and then starting the stamping cylinder 503, the stamping cylinder 503 drives the upper die 501 to move downward. After the upper die 501 descends to a certain position, the arc structure of the upper die 501 will push the beam tube workpiece 103 into the arc structure of the lower die 102, so that the upper die 501 and the lower die 102 cooperate to achieve stamping forming of the beam tube workpiece 103.

[0037] Embodiment 2, on the basis of embodiment 1, a guide groove 101 is opened on the front side of the supporting base plate 1; the bottom of the guide groove 101 is an inclined structure; a beam tube workpiece 103 is placed on the lower mold 102; after the upper mold 501 moves downward to a certain position along the track plate 5, the arc-shaped structure part of the upper mold 501 will enter the arc-shaped structure part of the lower mold 102; the push rod 401 is an L-shaped structure; a spring 402 is embedded between the inner side wall of the push rod 401 and the rear side wall of the supporting base plate 1; a push piece 403 is fixedly installed at the front end of the push rod 401 by bolts; the push piece 403 is an arc-shaped structure; transmission plates 404 are fixedly installed on the left and right sides of the push rod 401.

[0038] When the upper die 501 descends to pre-press the beam tube workpiece 103, the upper die 501 will also descend with the trigger pull plate 504 and the transmission pull column 505. During the descending process, since the transmission pull column 505 is still sliding inside the transmission groove 405, when the upper die 501 has not yet contacted the beam tube workpiece 103, the transmission pull column 505 will descend and utilize the inclined structure of the transmission groove 405 to drive the transmission plate 404, the push rod 401 and the push piece 403 to move backward, so that the push piece 403 withdraws from the lower die 102, thereby preventing the push piece 403 from affecting the normal progress of the stamping work.

[0039] Embodiment 3, on the basis of embodiment 2, when the upper mold 501 is in a high position, the pusher 403 will be located in the arc-shaped structure part of the lower mold 102; a transmission groove 405 is opened on the outer side of the transmission plate 404; the top of the transmission groove 405 is an inclined structure; the top of the track plate 5 is also fixedly installed with a support top plate 502 by bolts; a punching cylinder 503 is fixedly installed at the center position of the top of the support top plate 502; the output end of the punching cylinder 503 is fixedly connected to the top of the upper mold 501; a trigger pull plate 504 is fixedly installed on the rear side of the upper mold 501 by bolts; a transmission pull column 505 is fixedly installed on the inner side of the trigger pull plate 504; the transmission pull column 505 is a cylindrical structure; the transmission pull column 505 is also slidably installed inside the transmission groove 405.

[0040] After the upper die 501 cooperates with the lower die 102 to realize the stamping forming of the cross beam tube workpiece 103, it is only necessary to start the stamping cylinder 503 to make it restore along the track plate 5 with the upper die 501. After restoration, the push rod 401, the transmission plate 404 and the push piece 403 will be restored under the action of the spring 402, so that the push piece 403 can push the pressed automobile front cross beam tube into the collection box 3 by moving forward to realize unloading.

[0041] Working principle: before the pressing process, the cross beam tube workpiece 103 is first placed on the lower die 102, and then the stamping cylinder 503 is started to drive the upper die 501 to move downward. During the movement, the upper die 501 will also bring the trigger pull plate 504 and the transmission pull column 505 down. During the descent, since the transmission pull column 505 is still sliding inside the transmission groove 405, when the upper die 501 has not yet contacted the cross beam tube workpiece 103, the transmission pull column 505 will descend and utilize the inclined structure of the transmission groove 405 to drive the transmission plate 404, the push rod 401 and the push piece 403 to move backward, so that the push piece 403 withdraws from the lower die 102, so as to prevent the push piece 403 from affecting the stamping process The operation is carried out normally, and after the upper mold 501 drops to a certain position, the arc structure of the upper mold 501 will push the beam tube workpiece 103 into the arc structure of the lower mold 102, so that the upper mold 501 and the lower mold 102 cooperate to realize the stamping forming of the beam tube workpiece 103. After the upper mold 501 and the lower mold 102 cooperate to realize the stamping forming of the beam tube workpiece 103, it is only necessary to start the stamping cylinder 503 to restore it along the track plate 5 with the upper mold 501. After restoration, the push rod 401, the transmission plate 404 and the push piece 403 will be restored under the action of the spring 402, so that the push piece 403 pushes the pressed front beam tube of the automobile into the collection box 3 by moving forward, and all processes are completed.
