Description

Technical Field

[0001] This utility model relates to the field of grooving mold technology, and in particular to a copper strip grooving mold. Background Technology

[0002] In the processing of Australian standard brass plugs, they are made from 6.3mm×1.6mm copper strips. The middle part of the product is reduced from 1.6mm to 1.0mm for circumferential coating. The current processing technology is to produce 6.3mm×1.6mm×24mm copper sheets using a stamping line, and then use an automatic milling machine to flatten them on both sides to achieve a thickness of 1.0mm.

[0003] The production molds of existing automatic milling machines have the following shortcomings:

[0004] 1. The maximum daily production capacity of an automatic milling machine is 12,000 pieces, requiring one person to operate it, resulting in low production efficiency.

[0005] 2. To avoid jamming on the milling machine track after stamping, the product needs to be deburred first, then milled flat, then deburred again, and then double-sided stamped, a total of 5 processes, which is complicated.

[0006] 3. Automatic milling machines perform double-sided grooving with a symmetry exceeding 0.05mm, resulting in a high rate of defective adhesive coating and a high scrap rate.

[0007] Therefore, this utility model provides a copper strip grooving mold. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a copper strip slotting mold.

[0009] To achieve the above objectives, this utility model adopts the following technical solution: a copper strip slotting mold, comprising:

[0010] The upper mold includes an upper cover plate, an upper mold base, an upper pad plate, and an upper template plate. The top of the upper template plate is fixedly installed with the bottom of the upper pad plate, the top of the upper pad plate is fixedly installed with the bottom of the upper mold base, and the top of the upper mold base is fixedly installed with the bottom of the upper cover plate.

[0011] The intermediate mold includes a stop plate and a stripper plate, wherein the bottom of the stop plate is fixedly installed with the top of the stripper plate;

[0012] The lower mold includes a lower template, a lower pad, and a lower mold base. The bottom of the lower template is fixedly installed with the top of the lower pad, and the bottom of the lower pad is fixedly installed with the top of the lower mold base.

[0013] Preferably, an inner guide post is provided between the upper mold, the middle mold and the lower mold, and an outer guide post is provided between the upper mold and the lower mold.

[0014] By setting internal guide pillars, the middle die can be used to guide the upper, middle and lower dies during the stamping process to prevent separation. External guide pillars can guide the upper and lower dies.

[0015] Preferably, the bottom of the upper die is fixedly installed with a punching and forming punch by screws or a pressure plate, and the top of the lower die is provided with a lower die cutting edge and a lower die forming insert.

[0016] By setting a punching and forming punch, it can be used in conjunction with components such as the lower die cutting edge and the lower die forming insert for punching and forming.

[0017] Preferably, a stripping forming insert is installed at the bottom of the stripping plate.

[0018] By setting a stripping insert, the formed copper strip can be ejected and stripped, preventing it from sticking to the middle mold.

[0019] Preferably, a material belt and a guide pin are installed on the top of the lower mold.

[0020] By setting up a material strip and guide pins, the material can be guided and transported on the lower die.

[0021] Preferably, the upper mold is equipped with an upper mold inserter, and the lower mold is equipped with a slider structure.

[0022] By setting up an upper die inserter and a slider structure, the copper strip can be slotted twice, consisting of a first rough cut and a second fine cut.

[0023] Preferably, the upper mold is equipped with a slider structure, and the upper mold and the lower mold are each equipped with two leveling inserts.

[0024] By setting up a slider structure and leveling inserts, the mold closing slider structure follows the closing side platen, which corrects the bending deformation and flattens the side burrs. At the same time, the upper and lower leveling inserts are used to ensure the flatness in the thickness direction and remove the upper and lower burrs.

[0025] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0026] The copper strip grooving die of this application can achieve double-sided grooving in addition to product stamping. It has a planer-type side grooving structure. The strip is 1.6mm thick and 6.3mm wide. Grooving in the 6.3mm direction is a first attempt in stamping. It also has the following advantages:

[0027] 1. Production capacity increased to 35,000 units / day, a 3-fold increase compared to the original process.

[0028] A single process achieves stamping, milling, embossing, and a final grinding of burrs. Two processes accomplish what used to be five, reducing production costs and improving production efficiency.

[0029] The mold has high processing precision, and the symmetry of double-sided slotting can reach 0.02mm, which improves the pass rate. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1-3A copper strip grooving mold includes an upper mold, comprising an upper cover plate 1, an upper mold base 2, an upper pad plate 3, and an upper template 4. The top of the upper template 4 is fixedly installed with the bottom of the upper pad plate 3, the top of the upper pad plate 3 is fixedly installed with the bottom of the upper mold base 2, and the top of the upper mold base 2 is fixedly installed with the bottom of the upper cover plate 1. A middle mold includes a stop plate 5 and a stripper plate 6, with the bottom of the stop plate 5 fixedly installed with the top of the stripper plate 6. A lower mold includes a lower template 7, a lower pad plate 8, and a lower mold base 9, with the bottom of the lower template 7 fixedly installed with the top of the lower pad plate 8, and the bottom of the lower pad plate 8 fixedly installed with the top of the lower mold base 9. This process increases production capacity to three times that of the original process. A single operation achieves stamping, milling, embossing, and a final deburring step, solving the problems of the original five operations in two steps. This reduces production costs, improves production efficiency, and provides high mold processing precision. The double-sided grooving symmetry can reach 0.02, improving the pass rate.

[0039] Reference Figure 2 An inner guide post 10 is provided between the upper mold, the middle mold and the lower mold, and an outer guide post 11 is provided between the upper mold and the lower mold. The inner guide post 10 is composed of mutually sliding sleeve rods, which facilitates the guidance between the upper mold, the middle mold and the lower mold. The outer guide post 11 is composed of sleeve rods, springs and sleeves, which facilitates the guidance of the upper mold and the lower mold.

[0040] Reference Figure 3 and Figure 4 The bottom of the upper die is fixedly installed with a punching and forming punch 12 by screws or pressure plates. The top of the lower die is equipped with a lower die cutting edge 14 and a lower die forming insert 15. The lower die cutting edge 14 and the lower die forming insert 15 can cooperate with the punching and forming punch 12 to perform punching and forming.

[0041] Reference Figures 2-4 The bottom of the stripper plate 6 is equipped with a stripper forming insert 13, which is adapted to the lower mold forming insert 15 on the top for easy stripping.

[0042] Reference Figure 4 The top of the lower mold is equipped with a material strip 16 and a guide pin 17. The material strip 16 is gradually advanced in the lower mold through the guide pin 17 on the lower mold.

[0043] Reference Figure 4 The upper mold is equipped with an upper mold insert 18, and the lower mold is equipped with a slider structure 19. The grooving process is not the traditional side punching process, but simulates the principle of a wood planer planing wood. The grooving amount is 0.15mm each time, and the grooving is divided into upper grooving and lower grooving.

[0044] 1. Upper grooving: This is achieved by the slider structure 19 fixed to the lower mold and the upper mold inserter 18, consisting of a first rough cut and a second fine cut, achieving a grooving depth of 0.3mm in two steps;

[0045] 2: Lower grooving: This is achieved by the slider structure 19 fixed to the lower mold and the upper mold inserter 18, consisting of a first rough cut and a second fine cut, achieving a grooving depth of 0.3mm in two steps.

[0046] Reference Figure 4 and Figure 5 The upper mold is equipped with a slider structure 20, and the upper and lower molds are each equipped with two flattening inserts 21. After the copper strip is stamped and slotted, it will bend and deform on the side due to the softness of the material, and there will be burrs on all four sides after slotting. The structure is a slider structure 20 at the front and back. When the mold closes, the slider closes and the side platers close to correct the bending deformation and flatten the side burrs. At the same time, the two flattening inserts 21 at the top and bottom are used to ensure the flatness in the thickness direction and remove the top and bottom burrs. After shaping and correction, the time of the subsequent grinding process can be reduced and the product qualification rate can be improved.

[0047] Working principle:

[0048] like Figure 1-5 As shown:

[0049] In use, the upper, middle, and lower dies are connected by inner guide pillars 10, and an outer guide pillar 11 is provided between the upper and lower dies to guide and buffer during the stamping process. The punching and forming punch 12 can cooperate with the lower die cutting edge 14 and the lower die forming insert 15 to perform stamping and forming. At the same time, the conveyor belt can be conveyed by the material strip 15 and the guide pin 17. The conveyor belt can be slotted by the upper die insert 18 and the slider structure 19. The bending deformation is corrected and the side burrs are flattened by the slider structure 20 and the flattening insert 21. At the same time, the upper and lower flattening inserts 21 are used to ensure the flatness in the thickness direction and remove the upper and lower burrs. After shaping and correction, the time of the subsequent grinding process can be reduced and the product qualification rate can be improved. In this way, the production capacity can be increased during the production process. At the same time, the overall production efficiency and overall precision can be improved by clamping the two processes.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
