Description

Technical Field

[0001] The utility model relates to the technical field of punching anti-slipping mechanisms, in particular to a punching anti-slipping mechanism. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). It generally includes a fixed die (usually the lower die) and a movable die (usually the upper die). The movable die is pushed by a cylinder to cooperate with the fixed die to complete the stamping of the workpiece. It has a simple structure, low cost, and a wide range of application markets.

[0003] However, after the existing stamping die is used to stamp the workpiece, the workpiece is easily stuck in the template, which makes it difficult to cut the material and seriously affects the stamping efficiency.

[0004] For this reason, we propose a punching anti-slip mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a punching anti-slip mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stamping anti-slip mechanism, including a base plate, a detection head is arranged in the base plate, a detection rod is fixedly connected to the lower end of the detection head, a No. 1 spring is fixedly connected to the lower end of the detection head, a pressing head is fixedly connected in the base plate, a protective shell is fixedly connected to the lower end of the base plate, a top cylinder is fixedly connected in the protective shell, a No. 2 spring is fixedly connected to the upper end of the top cylinder, a push plate is fixedly connected to the upper end of the No. 2 spring, a downward pressure cylinder is arranged on the upper end of the base plate, a sensing head is fixedly connected to the outer end of the downward pressure cylinder, a support plate is fixedly connected to the driving end of the downward pressure cylinder, and a top pressure head is fixedly connected to the upper end of the support plate.

[0007] Preferably, when the detection head is not under pressure, its height is slightly higher than the upper end surface of the base plate, the detection rod is located in spring No. 1, the lower end of the spring No. 1 is fixed in the base plate, the pressing head is located in spring No. 1, the lower end of the detection rod can be connected to the pressing head, and the sensing head can be connected to the top pressure head.

[0008] Preferably, the driving end of the downward pressure cylinder is fixedly connected with a connecting plate, the lower end of the connecting plate is provided with an upper template, the connecting plate and the upper template are connected by bolts, and the lower end of the upper template is fixedly connected with a protrusion and a positioning rod.

[0009] Preferably, the lower end of the support plate is fixedly connected to a telescopic rod, and the lower end of the telescopic rod is fixedly connected to a pressure plate. When the downward pressure cylinder is not pressed down, the height of the pressure plate is lower than the protrusion and the positioning rod at the lower end of the upper template. A No. 3 spring is fixedly connected between the pressure plate and the support plate, and the telescopic rod is located in the No. 3 spring.

[0010] Preferably, a lower template is provided on the upper end of the base plate, and the lower template is located at the lower end of the upper template. A positioning hole is opened in the lower template, and the positioning rod can be inserted in the positioning hole. A groove is opened in the lower template, and the protrusion of the upper template can be inserted in the groove of the lower template. The No. 2 spring and the push plate are located in the groove of the lower template.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a push plate in the bottom plate. When the upper template cooperates with the lower template to punch the workpiece, the pressure plate presses on the upper end of the workpiece, so that the workpiece can press the detection head and the detection rod downward, so that the detection rod will be connected with the pressing head. When the punching of the workpiece is completed, the upper mold and the pressure plate leave the workpiece. At this time, the No. 1 spring and the No. 2 spring will provide an upward thrust to the workpiece through the detection head and the push plate. The downward pressure cylinder rises to make the induction head contact with the push head. At this time, if the detection rod and the detection head have not been separated, the push cylinder will be started to push the push plate upward, so as to push the workpiece out of the groove, thereby avoiding it from being stuck in the groove. The utility model solves the problem that the existing stamping mold, after the workpiece is punched, the workpiece is easily stuck in the template, thereby causing difficulty in cutting.

[0013] The utility model is provided with a pressing plate. When the pressing cylinder pushes the upper mold downward, the pressing plate will first contact the workpiece and, under the action of the No. 3 spring, can squeeze and fix the workpiece. After the workpiece is punched, the pressing cylinder rises, and the pressing plate will not directly rise with the No. 3 spring under the action of the No. 3 spring. Therefore, when the upper mold is separated from the lower mold, the pressing plate will continue to press the workpiece downward, thereby preventing the workpiece from being stuck on the upper mold.

When the detection head 2 is pressed down, the No. 1 spring 4 can shrink, so that the detection head 2 can be retracted into the bottom plate 1, a pressing head 5 is fixedly connected in the bottom plate 1, and the pressing head 5 is located in the No. 1 spring 4. The lower end of the detection rod 3 can be connected to the pressing head 5, and a protective shell 6 is fixedly connected to the lower end of the bottom plate 1, and the protective shell 6 is used for To protect the internal equipment, a top cylinder 7 is fixedly connected in the protective shell 6, a No. 2 spring 8 is fixedly connected to the upper end of the top cylinder 7, a push plate 9 is fixedly connected to the upper end of the No. 2 spring 8, a downward pressure cylinder 10 is arranged on the upper end of the bottom plate 1, a sensing head 11 is fixedly connected to the outer end of the downward pressure cylinder 10, a support plate 12 is fixedly connected to the driving end of the downward pressure cylinder 10, a top pressure head 13 is fixedly connected to the upper end of the support plate 12, the sensing head 11 can be connected to the top pressure head 13, when the sensing head 11 is connected to the top pressure head 13, if the detection rod 3 and the pressing head 5 are still connected, the sensing head 11 will start the top cylinder 7, if the detection rod 3 and the pressing head 5 are separated, the top cylinder 7 will not be started.

[0020] A connecting plate 14 is fixedly connected to the driving end of the downward pressure cylinder 10, and an upper template 15 is arranged at the lower end of the connecting plate 14. The connecting plate 14 and the upper template 15 are connected by bolts. A lower template 20 is arranged at the upper end of the base plate 1, and the lower template 20 is located at the lower end of the upper template 15. A positioning hole 21 is provided in the lower template 20, and a protrusion and a positioning rod 16 are fixedly connected to the lower end of the upper template 15. The positioning rod 16 can be inserted in the positioning hole 21. A groove is provided in the lower template 20, and the protrusion of the upper template 15 can be inserted in the groove of the lower template 20, so that the workpiece can be clamped and stamped. The No. 2 spring 8 and the push plate 9 are located in the groove of the lower template 20.

[0021] A telescopic rod 17 is fixedly connected to the lower end of the support plate 12, and a pressing plate 18 is fixedly connected to the lower end of the telescopic rod 17. The telescopic rod 17 is used to support the pressing plate 18 so that it can only move up and down without tilting. When the downward cylinder 10 is not pressed down, the height of the pressing plate 18 is lower than the protrusion and positioning rod 16 at the lower end of the upper template 15. Therefore, the pressing plate 18 will first contact the workpiece during stamping, thereby fixing it before the upper template 15 stamps the workpiece. A No. 3 spring 19 is fixedly connected between the pressing plate 18 and the support plate 12, and the telescopic rod 17 is located in the No. 3 spring 19.

[0022] Place the workpiece on the lower template 20, then start the downward pressure cylinder 10 to drive the support plate 12, the pressure plate 18, and the upper template 15 to press down. The pressure plate 18 will first contact the workpiece and fix it under the action of the No. 3 spring 19. At this time, the detection head 2 in the bottom plate 1 will shrink into the bottom plate 1 under the downward pressure of the workpiece, and the detection rod 3 can contact the pressing head 5. Then, the upper template 15 cooperates with the lower template 20 under the action of the downward pressure cylinder 10 to punch the workpiece;

[0023] When the stamping is completed, the downward pressure cylinder 10 drives the upper template 15 to rise, and the pressure plate 18 will not directly follow it up due to the action of the No. 3 spring 19, so it can continue to fix the workpiece, thereby preventing the workpiece from following the rise of the upper template 15, thereby preventing the workpiece from being stuck on the upper template 15. When the pressure plate 18 also leaves the workpiece, the No. 1 spring 4 and the No. 2 spring 8 will provide an upward thrust to the workpiece through the detection head 2 and the push plate 9 (if the workpiece is tightly stuck in the groove of the lower template 20, it will be difficult to push the workpiece out by the thrust of the No. 1 spring 4 and the No. 2 spring 8). The downward pressure cylinder 10 continues to rise when the sensor head 11 contacts the push head 13. At this time, if the detection rod 3 and the detection head 2 have not been separated, the sensor head 11 will control the push cylinder 7 to start and push the push plate 9 upward to push the workpiece out of the groove.
