Description
TECHNICAL FIELD

[0002] In the production process of the progressive die, when the feeding step distance is less than or equal to 1.5 mm, the die guide pin can automatically guide the material belt, when the feeding step distance is greater than 1.5 mm, the die will be pressed and broken; and some fluctuations of the feeding device in the die or the feeding machine will occasionally cause the feeding step distance to be too much or too little. Therefore, the sensor arranged at the tail end of the die is the key to control the pressing of the machine tool, the existing sensor at the tail end of the die cannot contact the end of the material belt when the feeding is less than the step distance, and the punch press stops; and when the feeding is greater than one step distance, the end of the material belt still contacts the sensor, the signal will still be transmitted to the punch press PLC, the punch press will continue to press, which causes the die to be pressed and broken, and affects the production efficiency.

[0028] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0029] This application provides a progressive die, which includes a structure to reduce the die failure rate. This structure enables accurate identification of non-standard incoming materials, ensuring that the material feeding pitch is accurate each time the progressive die performs a punching operation, effectively reducing the possibility of die damage due to punching failure.
[0030] Reference Figures 1 to 3 The structure for reducing mold failure rate in this application includes a mounting base 100, a sensing element 600, and a sensor 700.
[0031] The mounting base 100 serves as the mounting reference for the sensing element 600 and the sensor 700, such as... Figure 2 As shown, the mounting base 100 is provided with a guide channel 800, and the sensor 600 is slidably disposed in the guide channel 800. Both ends of the sensor 600 are exposed outside the guide channel 800. One end of the sensor 600 is provided with a trigger end 620, and the other end is provided with a sensing end 630 to restrict the sensor 600 from leaving the guide channel 800. An elastic element 500 is provided between the trigger end 620 and the mounting base 100. Under the action of the elastic element 500, the trigger end 620 has a tendency to move in a direction away from the mounting base 100, and the sensor 700 is used to detect the sensing end 630.
[0032] In use, the structure for reducing die failure rate of the application is installed at the tail end of the lower die seat of the continuous die, and the trigger end 620 faces the feeding direction of the continuous die, in the untriggered state, part of the sensing end 630 abuts against the mounting seat 100, and the sensing end 630 is between the mounting seat 100 and the sensing range of the inductor 700. When the lower die seat of the continuous die starts to feed, the material steps under the pushing of the continuous die and pushes against the trigger end 620, the trigger end 620 is pushed by the material to compress the elastic member 500, at the same time, the sensing end 630 also moves synchronously, and the sensing range of the inductor 700 is on the movement path of the sensing end 630. After the material is fed in place, if the sensing end 630 is in the sensing range of the inductor 700, the continuous die performs the die cutting operation, otherwise the continuous die does not perform the die cutting operation. When the die cutting operation of the continuous die is completed and the material is removed, the sensing member 600 returns to the original position under the action of the elastic member 500, so as to detect the feeding of the material in place for the next time.
[0033] The feeding of the material is sensed by the trigger end 620. If the feeding of the material is less than the step distance of one continuous die, the movement distance of the sensing member 600 driven by the material is reduced, the sensing end 630 does not reach the detection range of the inductor 700, and the die cutting operation program of the continuous die is not started. If the feeding of the material is greater than the step distance of one continuous die, the movement distance of the sensing member 600 driven by the material is increased, and the sensing end 630 exceeds the detection range of the inductor 700, and the die cutting operation program of the continuous die is not started.
[0034] Only when the feeding of the material is equal to the step distance of one continuous die, the inductor 700 can sense it, and only in this state the continuous die can be triggered to perform the die cutting operation. Compared with the prior art, the structure for reducing die failure rate of the application can detect more or less feeding step distance of the material, ensure stable and accurate triggering of the die cutting of the continuous die, and reduce the probability of damage to the die and the material.
[0035] In some embodiments, as shown in Figures 2 to 4 The top of the mounting seat 100 is provided with a first channel 110 and a limiting member 400, part of the sensing member 600 is located in the first channel 110, the limiting member 400 is detachably connected with the mounting seat 100, and the limiting member 400 covers the first channel 110 to form a guide channel 800. The limiting member 400 is arranged to form the key of the guide channel 800, and also facilitates the sensing member 600 to be put into the guide channel 800, and facilitates disassembly.
[0036] In some specific embodiments, the limiting member 400 can be provided with a second groove 420 on one side of the mounting base 100. When the limiting member 400 is connected to the mounting base 100, the second groove 420 corresponds to the first groove 110, that is, the second groove 420 cooperates with the first groove 110 to form the guide channel 800. Thus, the guide channel 800 has an adjustable space.
[0037] Further, the limiting member 400 is connected to the mounting base 100 by screwing. Specifically, the limiting member 400 is provided with a through hole or a counterbore for a bolt, and the mounting base 100 is provided with a threaded hole for the bolt. The bolt and the threaded hole are cooperated to lock the limiting member 400 to the mounting base 100.
[0038] In some embodiments, as shown in Figure 5 The sensing member 600 includes a sensing member 600 body. One end of the sensing member 600 body is bent in a radial direction to form a triggering end 620, and the other end of the sensing member 600 body is bent in a radial direction to form a sensing end 630.
[0039] In some specific embodiments, the triggering end 620 extends in a vertical direction, and the sensing end 630 extends in a horizontal direction. In actual use, the sensing member 600 body is slidingly arranged in the guide channel 800. Since the sensing end 630 and the triggering end 620 cannot enter the guide channel 800, the sensing member 600 can be limited to disengage from the guide channel 800.
[0040] In some embodiments, as shown in Figure 1 The elastic member 500 is arranged between the triggering end 620 and the limiting member 400. In other embodiments, the elastic member 500 can also be arranged between the sensing end 630 and the limiting member 400.
[0041] The elastic member 500 is a spring.
[0042] When the elastic member 500 is arranged between the triggering end 620 and the limiting member 400, as shown in Figure 6 The side of the limiting member 400 facing the triggering end 620 has a positioning hole 410 for spring positioning. The positioning hole 410 is used to position the spring, so as to avoid dislocation or inaction of the spring caused by repeated compression.
[0043] In some embodiments, the sensing end 630 has a sensing surface. The width of the sensing surface is 6 times the width of the detection beam of the sensor 700, and the width of the sensing surface is 2 times the feeding pitch of the continuous die.
[0044] In the embodiments of the present application, the inductor 700 is a photoelectric inductor 700, the diameter of the detection light beam of the inductor 700 is 0.5 mm, the width of the sensing surface of the sensing end 630 is 3 mm, and the feeding step distance of the continuous die of the present application is 1.5 mm. By reasonably setting the width of the sensing surface and the moving range of the sensing member 600, the accuracy of the material sensing can be effectively ensured.
[0045] In some embodiments, the inductor 700 is adjustable in position along the setting direction of the guide channel 800. Specifically, the inductor 700 is adjustably arranged on the mounting seat 100 through the adjusting member 300. Specifically, the inductor 700 is fixed on the adjusting member 300 through bolts, the adjusting member 300 is connected to the mounting seat 100 through bolts, the waist round hole 310 is arranged on the adjusting member 300, the bolts are threadedly connected to the mounting seat 100 after passing through the waist round hole 310, and the setting direction of the waist round hole 310 is parallel to the sliding direction of the sensing member 600. When it is necessary to adjust the sensing position of the inductor 700, the bolts are loosened, and then the adjusting member 300 is pushed to adjust the position of the inductor 700.
[0046] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
