Description

Technical Field

[0001] The utility model relates to the technical field of cutting and punching devices, in particular to a cutting and punching device for electronic moulds. Background Art

[0002] Electronic molds are tools used to shape and manufacture various components in electronic products. They achieve the processing of the object's appearance by changing the physical state of the material. They are widely used in processes such as punching, die forging, cold heading, and extrusion. Their design is complex and requires high precision. They are an indispensable part of modern manufacturing.

[0003] At present, in the process of making electronic molds, it is sometimes necessary to stamp and cut them at the same time. The Chinese utility model patent with the authorized public number CN 210648037 U mentions: "A stamping mold 7 and a cutting knife 8 are fixed to the bottom of the mounting plate 6. The cutting knife 8 is located on one side of the stamping mold 7, and the cutting knife 8 cooperates with the cutting groove 2, and the stamping mold 7 cooperates with the stamping groove 10." That is, in this existing technology, a single cutting knife is used to cut from the top of the electronic mold. This cutting method requires a large cutting depth for the cutting knife to completely cut off the electronic mold.

Subsequent stamping will cause the stamping mold to over-stamp the inner wall of the stamping groove, reducing its service life. Therefore, a new type of cutting and stamping device for electronic molds is needed to solve the above problems. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] The present embodiment provides a cutting and punching device, which is mainly used to solve the problem that when the current cutting and punching device is punching an electronic mold of a certain thickness, the cutting knife cuts halfway and the punching mold may have been punched. The subsequent punching will cause the punching mold to over-punch the inner wall of the punching groove, thereby reducing its service life. The following technical solutions are provided. Figure 1-Figure 5 Give detailed instructions:

[0024] A cutting and punching device comprises: a mounting frame 1 with cutting knives 2 provided on the top and bottom, and a stamping lower die 3 and a stamping upper die 4 are sequentially installed on the mounting frame 1. When in use, after the user places the electronic mold on the surface of the mounting frame 1, the user can control the two cutting knives 2 to move closer to or away from each other through the first driving unit 5, while controlling the stamping upper die 4 to move closer to the stamping lower die 3, thereby achieving the stamping and cutting of the electronic mold. The cutting is performed by the two cutting knives 2, so that the downward pressure of the stamping upper die 4 is small, effectively reducing wear. The main components of the mounting frame 1 are: a main frame with a mounting plate 102 fixedly installed on the surface The main frame 101 is provided with a through slot for inserting two cutting knives 2, wherein the main components of the first driving unit 5 are: two rotating rods 501 respectively rotatably plugged into the main frame 101 and the mounting plate 102. When in use, the user can control the two rotating rods 501 to rotate in opposite directions through the second driving unit 502, thereby driving the two driving wheels 503 respectively fixedly sleeved on the surfaces of the two rotating rods 501 to rotate (although the two driving wheels 503 are circular, the place where the two rotating rods 501 are fixedly inserted is not the center of the circle), because the surfaces of the two driving wheels 503 are rotatably sleeved with driving rings 504 (through the bearing), the surfaces of the two drive rings 504 are fixedly mounted with straight plates 505, and the surfaces of the two straight plates 505 are opened with slots 506, the inner walls of the two slots 506 are slidably plugged with plug rods 507, and the surfaces of the two plug rods 507 are provided with two annular protrusions 508 (respectively fitted on the surfaces of the two straight plates 505), and because the surfaces of the mounting plate 102 and the main frame 101 are fixedly mounted with mounting blocks 509, the two plug rods 507 are respectively slidably plugged into the surfaces of the two mounting blocks 509. Therefore, when the two drive wheels 503 rotate in opposite directions, they will synchronously drive the two drive wheels 503 to rotate, and the two drive wheels 503 will rotate synchronously. 03 will respectively drive the two driving rings 504 to swing, and the two driving rings 504 will further drive the two cutting knives 2 installed on the surfaces of the two driving rings 504 through the installation unit 510 to swing while realizing the cutting of the electronic mold. (In this process, the two slave rods 507 will slide on the inner walls of the two mounting blocks 509 and at the same time slide on the inner walls of the two slots 506 to ensure the stability of the swinging of the driving ring 504). At the same time, in order to further control the stamping degree of the stamping upper die 4, the user can also install the other end of one of the rods 507 on the surface of the stamping upper die 4 through the adjusting unit while controlling the distance between the stamping upper die 4 and one end of the rod 507.

[0025] By arranging a cutting knife 2 above and below the mounting frame 1, when in use, the user places the electronic mold on the surface of the mounting frame 1 and the stamping lower mold 3, and then the first driving unit 5 can drive the stamping upper mold 4 close to the stamping lower mold 3 to achieve the purpose of stamping. At the same time, the two cutting knives 2 will also approach the electronic mold at the same time to jointly achieve the cutting of the electronic mold. This method makes the degree of downward pressure of the stamping upper mold 4 lower, reducing the degree of wear of the stamping upper mold 4 and the stamping lower mold 3.

[0026] By threading a distance adjusting rod 5111 into one end of one of the insertion rods 507, and rotating the other end of the distance adjusting rod 5111 into the surface of the stamping lower die 3, when in use, the user can adjust the distance adjusting rod 5111 to control the T-shaped surface of the surface of the stamping lower die 3 to slide on the inner wall of the distance adjusting groove 5113, thereby further controlling the degree to which the stamping upper die 4 presses down the stamping lower die 3.

[0027] like Figures 1 to 4As shown, in some embodiments, the main components of the second drive unit 502 are: a motor 5024 fixedly mounted on the surface of the mounting plate 102, and a gear 5021 is fixed at one end of the two rotating rods 501, and the two gears 5021 are meshed with each other, and a transmission wheel 5022 is fixedly mounted on the surface of one of the gears 5021, and another transmission wheel 5022 is rotatably plugged into the surface of the mounting plate 102. Therefore, when in use, the user controls the output end of the motor 5024 to rotate by the controller 5025 fixedly mounted on the surface of the main frame 101, which can drive the two transmission wheels 5022 connected by the transmission belt 5023 to rotate simultaneously, thereby realizing the driving of one of the gears 5021. Because the two gears 5021 are meshed with each other, the two gears 5021 respectively drive the two rotating rods 501 to rotate in opposite directions. The main components of the mounting unit 510 are: a plurality of mounting bolts 5103, The surface of the ring 504 is fixedly installed with a fixing plate 5101. When in use, the user needs to slide the two cutting knives 2 into the inner walls of the two mounting grooves 5102 respectively opened on the surfaces of the two fixing plates 5101, and then thread a number of mounting bolts 5103 into the surfaces of the two cutting knives 2 and then thread them into the inner walls of the two mounting grooves 5102 respectively, so as to achieve the installation of the two cutting knives 2. The main components of the distance adjustment unit 511 are: a distance adjustment rod 5111 threadedly inserted into one end of one of the insertion rods 507, and a distance adjustment groove 5113 is opened on the surface of the mounting plate 102, and at the same time, a T-shaped plate 5112 is fixedly installed on the surface of the stamping lower die 3, and the T-shaped plate 5112 is slidably inserted into the inner wall of the distance adjustment groove 5113. Therefore, by rotating the distance adjustment rod 5111, the stamping lower die 3 can be driven to move. In this process, the T-shaped plate 5112 slides on the inner wall of the distance adjustment groove 5113, thereby achieving the control of the downward pressure of the stamping lower die 3.

[0028] like Figure 1 、 Figure 2 、 Figure 5 As shown, in some embodiments, a limiting unit 6 is further included, which is used to limit the position of the stamping lower die 3 above the main frame 101. The main components of the limiting unit 6 are: a limiting groove 601 opened on the surface of the main frame 101. When in use, the user slides the limiting protrusion 602 installed on the surface of the stamping lower die 3 into the inner wall of the limiting groove 601, and then slides several fixing rods 603 fixed on the surface of the limiting protrusion 602 into the inner wall of the limiting groove 601 (several fixing rods 603 are respectively arranged at the four corners of the limiting protrusion 602), and finally, the limiting nuts 604 are threaded on the surfaces of the several fixing rods 603 to complete the installation of the stamping lower die 3 on the inner wall of the limiting groove 601.

[0029] The working process of the present invention is as follows: first, the user places the electronic mold on the surface of the main frame 101, and then controls it to slide at a uniform speed on the surface of the main frame 101 through an existing conveyor or other device. During the sliding process, the user can control the output end of the motor 5024 to rotate through the controller 5025, thereby sequentially driving the two transmission wheels 5022, the two gears 5021 to rotate, the two rotating rods 501 to rotate in opposite directions, the two driving wheels 503 to rotate in opposite directions, the two driving rings 504 to rotate and swing in opposite directions, and the two cutting knives 2 to approach each other. During this process, one of the insertion rods 507 will also synchronously drive the stamping upper die 4 to perform stamping;

[0030] Secondly, before the above operation, the user can rotate the distance adjusting rod 5111 to drive the T-shaped plate 5112 on the surface of the stamping lower die 3 to slide on the inner wall of the distance adjusting groove 5113. During subsequent use, the stamping lower die 3 and the two cutting knives 2 move synchronously. Therefore, the previous adjustment of the stamping lower die 3 can adapt to the thickness of different electronic molds, that is, while the two cutting knives 2 complete the cutting, the stamping upper die 4 completes the stamping, reducing the degree of wear of the stamping upper die 4.

[0031] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
