[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4 This utility model provides an embodiment of a die workpiece suitable for punching copper foil, comprising a base plate 1, a lower die 2 disposed above the base plate 1, and support plates 5 symmetrically fixedly installed on both sides below the lower die 2, the lower ends of the support plates 5 being fixedly connected to the base plate 1. A material groove 201 is disposed above the interior of the lower die 2, and a punching hole 202 is disposed below the interior of the lower die 2, communicating with the material groove 201. Side grooves 203 are symmetrically disposed along the front and rear ends of the material groove 201 inside the lower die 2, communicating with the material groove 201. Slide plates 14 are symmetrically arranged on both sides inside 201. The front and rear ends of slide plates 14 extend into the interior of two side grooves 203 respectively. A fixing plate 15 is arranged below slide plates 14. A threaded rod 17 is rotatably installed on the top of the fixing plate 15. The upper end of the threaded rod 17 is threadedly connected to and passes through slide plates 14. Guide posts are symmetrically fixed on the front and rear ends above slide plates 14 respectively. The upper ends of the guide posts slide through slide plates 14, so as to guide the lifting and lowering movement of the fixing plate 15 and increase the linear stability of the lifting and lowering movement of the fixing plate 15.
[0024] By setting up structures such as the slide plate 14, the fixing plate 15, and the threaded rod 17, the copper foil is equipped with an auxiliary fixing function, which effectively solves the problem of copper foil deviation during the punching process. Specifically, when the copper foil is punched, the copper foil is placed in the material trough 201. By sliding the slide plate 14, the fixing plate 15 is moved to the upper end of the copper foil. Then, the threaded rod 17 is turned to move the fixing plate 15 downward, pressing and fixing the copper foil. This improves the accuracy of copper foil punching, reduces the scrap rate caused by copper foil deviation, and improves production efficiency and product quality.
[0025] Furthermore, a handwheel 18 is fixedly installed above the threaded rod 17, and a rubber pad 16 is fixedly installed below the fixing plate 15.
[0026] The handwheel 18 makes the operation of the threaded rod 17 more effortless and convenient, allowing the fixing plate 15 to be raised and lowered without the need for tools, thus improving the convenience and efficiency of operation. The installation of the rubber pad 16 effectively protects the surface of the copper foil, avoiding scratches or indentations that may occur during the pressing process. At the same time, its elastic properties ensure the uniform distribution of the pressing force, further enhancing the fixing effect and increasing practicality.
[0027] Furthermore, a straight rod 19 is provided inside the side groove 203. Both ends of the straight rod 19 are fixedly connected to the lower mold 2, and the straight rod 19 slides through the slide plate 14.
[0028] The straight rod 19 guides the movement of the slide plate 14, enhancing its stability and enabling it to move in a stable straight line, preventing wobbling or deviation. This improves the clamping accuracy of the fixing plate 15 and increases its practicality.
[0029] Furthermore, a collection hopper 6 is provided in the middle below the lower mold 2, and a material discharge pipe 7 is fixedly installed below the collection hopper 6. The lower end of the material discharge pipe 7 extends to the lower part of the base plate 1 and a collection box 8 is fixedly installed thereon. An inner groove 9 is provided inside the collection box 8, and the front end of the inner groove 9 extends to the front end surface of the collection box 8, so that the inner groove 9 can be pulled out from the collection box 8.
[0030] The setup of the collection hopper 6, the discharge pipe 7, and the collection box 8 enables the centralized collection of copper foil punching waste, avoiding the impact of waste accumulation on the mold and working environment. Furthermore, the pull-out design of the inner tank 9 makes waste cleaning more convenient and increases practicality.
[0031] Furthermore, a lifting plate 3 is provided above the lower mold 2, and an upper mold 4 is fixedly installed in the middle below the lifting plate 3 by bolts. A top plate 10 is provided above the lifting plate 3, and a hydraulic cylinder 13 is fixedly installed in the middle above the top plate 10. The hydraulic cylinder 13 is externally connected to an oil pumping device, and the piston rod end of the hydraulic cylinder 13 slides through the top plate 10 and is fixedly connected to the lifting plate 3.
[0032] The hydraulic cylinder 13 can drive the lifting plate 3 to move up and down, which in turn can drive the upper mold 4 to move up and down to perform the copper foil punching work, thus increasing its practicality.
[0033] Furthermore, columns 11 are fixedly installed at the four corners below the top plate 10, and the lower ends of the columns 11 are fixedly connected to the bottom plate 1. Guide sleeves 12 are fixedly installed at the four corners outside the lifting plate 3, and the guide sleeves 12 are slidably disposed on the outside of the columns 11.
[0034] The cooperation between the guide sleeve 12 and the column 11 ensures that the lifting plate 3 always moves in a straight line during the lifting process, avoiding swaying or deviation, and improving the movement stability and punching accuracy of the lifting plate 3.
[0035] Working principle: During use, when the copper foil is being punched, the copper foil is placed in the material groove 201 of the lower die 2. The fixed plate 15 is moved above the copper foil by sliding the sliding plate 14. Then, the threaded rod 17 is rotated by the handwheel 18 to drive the fixed plate 15 to move downward. The copper foil is pressed and fixed by the rubber pad 16 to ensure that the copper foil does not shift during the punching process. Subsequently, the lifting plate 3 is driven by the hydraulic cylinder 13 to move the upper die 4 downward to punch the copper foil. The punched waste falls into the collection hopper 6 through the punching hole 202 and enters the inner groove 9 of the collection box 8 through the discharge pipe 7 for easy centralized cleaning.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
