Description

Technical Field

[0001] The present application relates to the technical field of switch panel processing tools, and in particular to a switch panel punching die. Background Art

[0002] Membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downward and contacts the plate of the lower circuit. When the finger is released, the contact of the upper circuit rebounds, the circuit is disconnected, and the loop triggers a signal. The membrane switch has a rigorous structure, beautiful appearance, and good sealing. It is moisture-proof and has a long service life. It is widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, automotive industry, smart toys, household appliances and other fields.

[0003] During the processing and production of the panel, since it has different components and the panel itself has a certain shape, it is necessary to punch the panel to make it punched into a specified shape; the traditional switch panel punching die is made of pure steel material, and the steel raw material is processed by a milling cutter to finally form a specified shape; in actual applications, the switch panel often has multiple points that need to be punched, such as the punching of the outer frame shape, some circular through-hole punching, and even some special shapes that need to be punched. It often takes a long time to form a matching die from steel raw materials, which is very unfavorable to production efficiency. Utility Model Content

[0004] The purpose of this application is to provide a switch panel punching die to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a switch panel punching die, including a main board, on which a first annular groove, a plurality of second annular grooves and a clamping groove are formed, and the second annular groove and the clamping groove are located within the annular range of the first annular groove;

[0006] a first blade strip, wherein the first blade strip is embedded in the first annular groove;

[0007] a second blade strip, wherein the second blade strip is embedded in the second annular groove;

[0008] A punching module, the punching module comprising a main body and a blade, the punching module being embedded in the clamping slot;

[0009] Wherein, the main board is made of plastic material, and the first blade, the second blade and the punching module are made of steel;

[0010] In the above implementation process, the punching die provided by the present scheme is composed of a composite of plastic material and steel, wherein the first blade is used to form the outer contour of the panel, the second blade can be used to form some conventionally shaped through holes, and the punching module is used to form some special shaped through holes; it is understandable that, compared with the traditional punching die, if it is necessary to form a die with multiple punching points, it takes a lot of time to mill off a large amount of steel to form the corresponding knife positions, and in the present scheme, the main board is used as the main body of the board, and the corresponding first annular groove and other groove structures are further opened thereon, and the corresponding blade and punching module are embedded in an embedded manner, which can be directly embedded and then used through a certain position adjustment, or it can be embedded in the steel block and then the point is concentratedly milled without large-scale milling; it can be seen that the present scheme effectively improves the production efficiency of the die and thus improves the overall production efficiency of the panel. In addition, this method can also effectively reduce production costs.

[0011] Preferably, the first annular groove and / or the second annular groove comprises a first groove body portion and a second groove body portion that are interconnected;

[0012] The first groove portion is close to the punched front side of the main board, and the second groove portion is close to the punched back side of the main board;

[0013] The first groove body parts are connected without interruption, and the second groove body parts are formed at intervals along the circumferential direction of the first groove body parts;

[0014] In the above implementation process, the first knife strip in this scheme serves as a part for forming the outer shape of the panel, and sometimes its range is large. If a full-through embedding method is adopted, unstable assembly is likely to occur. For this reason, further improvements are made in this scheme, wherein the first groove body part is a completely connected uninterrupted groove body, thereby ensuring the continuity of the entire punching blade surface of the first knife strip, and the second groove body is arranged in an interval manner, which can avoid the first annular groove being fully through, thereby ensuring the embedding stability of the first knife strip, ensuring stability during subsequent punching, and ensuring production quality; the same is true for the second annular groove.

[0015] Preferably, a protruding tooth structure is formed on a side of the first blade and / or the second blade facing away from the cutting surface thereof;

[0016] In the above implementation process, the protruding tooth structure can be understood as being adapted to the second grooves arranged at intervals, thereby achieving sufficient embedding and improving the stability of assembly.

[0017] Preferably, the cross section of the main body of the punching module is rectangular;

[0018] In the above implementation process, the cross-section of the punching module is rectangular, that is, during production, the block of steel can be directly assembled in the corresponding slot of the mainboard, and then the corresponding shape is milled out by a milling cutter to form the blade part.

[0019] Preferably, a protrusion is formed on the outer peripheral wall of the main body of the punching die;

[0020] Preferably, the cross section of the protrusion is trapezoidal;

[0021] Preferably, the cross section of the protrusion is rectangular;

[0022] In the above implementation process, the protrusions formed on the outer peripheral wall of the punching die main body can provide more limiting points between the punching die and the main board, thereby improving the stability of embedded assembly.

[0023] Preferably, the mainboard is made of PVC material;

[0024] In the above implementation process, the mainboard is made of PVC material, which can ensure that the mainboard has sufficient hardness and corresponding wear resistance, thereby effectively extending the service life without the need for frequent mold replacement; further, it also has a certain waterproof performance, which can effectively delay the time when rust appears on the cutting mold.

[0025] Preferably, first mounting holes are provided at positions near the four corners of the main board along the thickness direction thereof;

[0026] Preferably, a first mounting groove is provided on a wall surface surrounding an edge of the mainboard;

[0027] In the above implementation process, the present solution sets a first mounting hole and a first mounting groove, and the user can select corresponding mounting points and mounting methods according to the actual assembly situation to improve its compatibility.

[0028] Compared with the prior art, the beneficial effect of the present application lies in that: the present solution uses the main board as the main body of the board, and further opens the corresponding first annular groove and other groove structures thereon, and embeds the corresponding knife strips and punching modules in an embedded manner. It can be used by directly embedding and adjusting a certain position, or it can be embedded in a steel block and then the point is concentratedly milled without the need for large-scale milling. It can be seen that the present solution effectively improves the production efficiency of the knife mold and thus improves the overall production efficiency of the panel. In addition, this method can also effectively reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS
