[0001] The utility model relates to the technical field of stamping equipment, in particular to a stamping die-cutting mechanism, a stamping component and sheet material processing equipment. Background Art

[0002] In the modern electronics industry, sheet materials such as copper foil and aluminum foil are key conductive materials. They are widely used in the manufacture of printed circuit boards (PCBs), the design of heat sinks, and battery packaging. These materials usually need to be precisely die-cut to obtain specific shapes and sizes to meet complex engineering design requirements. However, due to the low hardness and brittleness of these sheet materials, they are easily affected by mechanical stress during the die-cutting process, resulting in processing defects.

[0003] Specifically, when using traditional punching or die-cutting machines to process materials such as copper foil and aluminum foil, the high pressure exerted by the blade or die on the material will cause the material to be squeezed and deformed at the cut. This deformation manifests as tearing, warping or wavy shapes at the cut edge, as well as small depressions or protrusions on the surface. These processing defects will not only cause thickness dimensional deviations in the product, affecting the structural strength and reliability of the product, but will also significantly affect the appearance quality of the product, making it unable to meet strict quality control standards.

[0004] In addition, due to the relatively high prices of materials such as copper foil and aluminum foil, any waste in the processing process will significantly increase the production cost. Therefore, developing a die-cutting and punching technology that can reduce material waste, improve processing accuracy and surface quality is of great significance to improving production efficiency and reducing costs.

[0007] In one embodiment of the present invention, the flattening mechanism includes a buffer and a pressing block, one end of the buffer is connected to the housing, and the other end is connected to the pressing block, and the pressing block presses the buffer to move relative to the cutter.

[0008] In one embodiment of the present invention, it comprises two cutters, which are arranged on two opposite sides of the flattening mechanism and are symmetrically arranged.

[0010] In one embodiment of the present invention, one end of the flattening mechanism away from the housing protrudes beyond the blade by 1.0-1.5 mm.

[0011] The utility model also provides a stamping assembly, which comprises at least one of the above-mentioned stamping and die-cutting mechanisms and a mounting plate, wherein at least one of the stamping and die-cutting mechanisms is connected to the mounting plate.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Embodiment 1

[0025] See also Figure 1As shown, the present embodiment provides a stamping and die-cutting mechanism, which includes: a shell 100; a flattening mechanism 300, wherein the flattening mechanism 300 is arranged inside the shell 100 and moves along the depth direction of the shell 100; at least one cutter 200, wherein at least one cutter 200 is arranged in contact with the outer wall of the flattening mechanism 300, and the cutter 200 includes a main body 220 and a blade 210, wherein the main body 220 is connected to the shell 100, and the blade 210 is arranged toward the component 500 to be punched, and the acute angle between the blade 210 and the main body 220 is in the range of 5 to 10°, and the end of the flattening mechanism 300 away from the shell 100 protrudes from the blade 210.

[0026] The punching and die-cutting mechanism described in the utility model punches and cuts the punching element 500 through at least one cutter 200, wherein the special angle setting between the blade 210 and the main body 220 can evenly disperse the punching and extrusion force outward, thereby achieving the effect of reducing the surface extrusion deformation. In addition, before the cutting process, the application also first squeezes and contacts the punching element 500 through the flattening mechanism 300, so that the surface of the punching element 500 remains highly flat, thereby improving the degree of coordination between the punching element 500 and the cutter 200, thereby maximizing its cutting efficiency and effect. Compared with the conventional punching technology at this stage, the application has significant advantages such as high processing efficiency, low cost and simple operation. Most importantly, the application can avoid edge deformation of the product, thereby making the product meet the precision design standards and appearance quality control requirements. It is a new type of punching and die-cutting mechanism with broad application prospects.

[0027] by Figure 1The stamping and die-cutting mechanism shown is a reference. In this embodiment, the housing 100 is preferably a horizontally arranged sheet-like element, which provides a connection and installation platform for the flattening mechanism 300 and at least one cutter 200. The flattening mechanism 300 is connected to the center of the lower surface of the housing 100, and the cutter 200 extends in the vertical direction and is arranged on one side of the flattening mechanism 300. Further, the present embodiment includes two of the cutters 200, which are arranged on opposite sides of the flattening mechanism 300, and the two cutters 200 are symmetrically arranged. Based on this, the present embodiment The housing 100 and the two cutters 200 in the housing 100 and the two cutters 200 jointly enclose a storage space, and the flattening mechanism 300 is arranged in this storage space. Specifically, the two cutters 200 in this embodiment are symmetrically arranged, which can perform synchronous stamping and cutting processing on the stamping element 500 from two directions during a stamping process. In other embodiments, the cutters 200 can be set to other numbers according to actual use requirements. Correspondingly, the housing 100 can also be set to other shapes or structures that can connect the flattening mechanism 300 and the cutters 200. The utility model does not impose specific restrictions on this. Specifically, the acute angle between the blade 210 and the main body 220 in this embodiment is 5°, thereby being able to guide the cutting direction of the stamping element 500 under the premise of concentrating the cutting stress, thereby maximizing the cutting effect and quality. In other embodiments, the acute angle between the blade 210 and the main body 220 can be adjusted within 5 to 10° according to the actual component properties or production and processing requirements.

[0028] In the present embodiment, in order to make the surface of the component to be punched 500 smooth before stamping and cutting, it is necessary to flatten it through the flattening mechanism 300 before the cutter 200 contacts the component to be punched 500. Furthermore, the flattening mechanism 300 in the present embodiment protrudes 1.0 mm from the blade at one end away from the shell 100. This ensures that the flattening mechanism 300 contacts the component to be cut first while avoiding affecting the cutting efficiency and effect of the cutter 200. In the actual production and processing process, the component to be cut is usually a sheet metal component with lower hardness. Combined with its actual thickness and processing requirements, the industry usually allows the flattening mechanism 300 to protrude 1.0-1.5 mm from the blade at one end away from the shell 100.

[0029] See also Figure 1As shown, the flattening mechanism 300 includes a buffer 310 and a pressure block 320. One end of the buffer 310 is connected to the housing 100, and the other end is connected to the pressure block 320. The pressure block 320 squeezes the buffer 310 to move relative to the cutter 200. In this embodiment, the buffer 310 is preferably a spring. In actual processing, the buffer 310 with different elastic moduli can be adjusted according to the quality of the different components to be punched 500. The pressure block 320 is preferably an elastic rubber. Further, the side of the pressure block 320 away from the buffer 310 is a plane. On the one hand, the elastic rubber pressure block 320 can evenly disperse its pressure. On the other hand, it also has a buffering effect, thereby protecting the flattening mechanism 300 and the component to be punched 500. In other embodiments, the buffer 310 can be set as other components or structures with compression and rebound effects, and the pressure block 320 can also be selected from other materials or shapes, and the utility model does not make specific restrictions on this.

Figure 2 As shown, the punching and die-cutting mechanism in this embodiment is different from the embodiment 1 in terms of the number of cutters 200, so other structures and connection methods are not described in detail here. Furthermore, the number of cutters 200 in this embodiment is 1. Specifically, during the punching process, the pressing block 320 squeezes the buffer member 310 to the top of the cutter 200.

[0033] See also Figure 3 As shown, this embodiment provides a stamping assembly 400, which includes at least one stamping die-cutting mechanism and a mounting plate 410 as described in the first embodiment, at least one of the stamping die-cutting mechanisms is connected to the mounting plate 410, specifically, a plurality of the stamping die-cutting mechanisms are provided in this embodiment, and the plurality of the stamping die-cutting mechanisms are connected to the mounting plate 410 in groups of two at intervals. Furthermore, this embodiment also includes a stamping moving device, the mounting plate 410 is provided with a positioning hole 420, and a connecting member passes through the positioning hole 420 to connect the mounting plate 410 and the stamping moving device.

[0034] The stamping assembly 400 in this embodiment also includes a control system, and the control system is connected to the stamping mobile device. In the actual operation process, the operator can control the working process of the stamping assembly 400 in real time through the control system, thereby improving the flexibility of the use of the stamping assembly 400, and can also preset parameters of the working process of the stamping assembly 400 through the control system, thereby improving the automation of the processing process of the stamping assembly 400.

[0035] Embodiment 4

In addition, before the cutting process, the present application also first squeezes and contacts the punching element 500 through the flattening mechanism 300, so that the surface of the punching element 500 remains highly flat, thereby improving the degree of coordination between the punching element 500 and the cutter 200, and thus maximizing its cutting efficiency and effect.
