Description

Technical Field

[0001] This application relates to the technical field of molding dies, and in particular to a one-time molding die for a flat wire buckle. Background Technology

[0002] With the rapid development of the electronics, electrical appliances and automotive industries, the demand for flat wire clips, as key components for fixing and connecting wire harnesses, has increased significantly. Traditional manual or semi-automatic processing methods can no longer meet the needs of efficient and high-precision production. At present, the industry is gradually transforming to fully automated processing equipment to improve production efficiency and product quality and reduce labor costs. The introduction of automated processing equipment has significantly improved the production speed and consistency of flat wire clips.

[0003] When processing existing buckles, they are mostly processed by using CNC machine tools for precise programming, and then using the CNC head to rotate and press and bend the buckle blank multiple times. The buckles after the stamping opening is then processed by bending.

[0004] Regarding the aforementioned technologies, the inventors discovered that the above-mentioned buckle processing requires multiple bending operations on the buckle blank, and the buckle forming requires multiple operations on a CNC machine tool, which is cumbersome, takes a long time, and has low buckle forming efficiency. Utility Model Content

[0005] To overcome the problems of existing buckle processing requiring multiple bending operations on the buckle blank, buckle forming requiring multiple CNC machine tool operations, cumbersome steps, long forming time, and low buckle forming efficiency, this application provides a one-time forming mold for flat wire buckles.

[0006] The technical solution for a one-time forming mold for flat wire buckles provided in this application is as follows: A one-time forming mold for a flat wire buckle includes an mounting ring, an assembly, a lower abutment mold, an upper abutment mold, an upper concave mold, and a lower convex mold. The mounting ring contains the assembly, which includes an assembly ring plate. The lower abutment mold is vertically slidably disposed at the bottom of the front end face of the assembly ring plate, and the upper abutment mold is vertically slidably disposed at the top of the front end face of the assembly ring plate. Lower convex molds are disposed on both sides of the lower abutment mold at the bottom of the front end face of the assembly ring plate, and upper concave molds are disposed on both sides of the upper abutment mold at the top of the front end face of the assembly ring plate. The upper abutment mold and the lower abutment mold are correspondingly fitted at the middle of their top ends, the upper concave mold and the two sides of the top end of the lower abutment mold are correspondingly fitted, and the lower convex mold and the lower side of the top end of the lower abutment mold are correspondingly fitted.

[0007] By adopting the above technical solution, the assembly ring plate and the mounting ring of the assembly component are fixedly assembled and connected into one piece during use. The metal sheet blank after punching and cutting is transported to the front side of the assembly ring plate of the assembly component. The metal sheet blank is pressed and bent by the upper die, the upper concave die and the lower convex die on the lower die, and the metal sheet blank is formed and pressed. In this way, the pressing and bending of the metal sheet blank is completed in one piece, reducing the flat wire buckle forming steps. With fewer steps, the forming time is shorter and the buckle forming efficiency is improved.

[0009] By adopting the above technical solution, the sliding strips on both end faces of the lower die, upper die, upper concave die, and lower convex die are used to slide and assemble the lower die, upper die, upper concave die, and lower convex die in front of the assembly ring plate. At the same time, the hole seats fixed at the ends of the lower die, upper die, upper concave die, and lower convex die are used to connect and assemble the driving components later, driving the lower die, upper die, upper concave die, and lower convex die to perform forming processing on the metal sheet blank.

[0012] Optionally, a second slide block is vertically fixed to the top of the front end face of the assembly ring plate, and the second slide block is slidably assembled with the slide bar on the upper die.

[0013] By adopting the above technical solution, the second slide fixed on the front end face of the assembly ring plate is slidably assembled with the slide bar on the upper die, which is used to vertically guide the upper die to slide vertically on the second slide, and to perform forming processing on the metal plate blank.

[0014] Optionally, the bottom of the front end face of the assembly ring plate is fixed with a fourth slide block on both sides of the lower die, and the fourth slide block is slidably assembled with the slide bar on the lower punch.

[0015] By adopting the above technical solution, the fourth slide fixed on the front end face of the assembly ring plate is slidably assembled with the slide bar on the lower punch, which is used to vertically guide the lower punch to slide vertically on the fourth slide, and to perform forming processing on the metal plate blank.

[0017] By adopting the above technical solution, the third slide block fixed on the front end face of the assembly ring plate is slidably assembled with the slide bar on the upper die, which is used to vertically guide the upper die to slide vertically on the third slide block, and to perform forming processing on the metal sheet blank.

[0018] Optionally, multiple slide blocks are evenly fixed on the rear end face of the mounting ring, and each slide block is vertically and slidably mounted with a positioning rod. A spring is sleeved on the positioning rod, and the two ends of the spring are respectively fixed to the top surface of the slide block and the bottom surface of the positioning rod.

[0019] By adopting the above technical solution, the mounting ring is fixed at the rear end of the slide and vertically slidably connected to a positioning rod. During installation, the positioning rod is pulled up vertically to deform the spring, which is used for the later assembly of the mounting ring in the assembly ring plate.

[0020] Optionally, multiple plate seats are evenly fixed on the rear end face of the assembly ring plate, and the multiple plate seats are slidably inserted into the positioning rod.

[0021] By adopting the above technical solution, the mounting ring is fixed at the rear end of the slide and vertically slidably connected to the positioning rod. During installation, the positioning rod is pulled up vertically, compressing the spring to deform. After the mounting ring is assembled in the assembly ring plate, the positioning rod is released and pushed into the plate seat under the action of the spring deformation force, thereby ensuring the stability of the fixed assembly of the mounting ring and the assembly ring plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: In use, the assembly ring plate and the mounting ring of the assembly component are fixedly assembled and connected as one piece. The metal sheet blank after punching and cutting is transported to the front of the assembly ring plate of the assembly component.

Then the pressing and bending of the metal sheet blank is completed in one piece, reducing the flat wire buckle forming steps. The number of steps is reduced, the forming time is shorter, and the buckle forming efficiency is improved. Attached Figure Description

The sliding seat 11 fixed at the rear end of the mounting ring 1 is vertically slidably connected to the positioning rod 12. During installation, the positioning rod 12 is lifted and moved vertically upward, compressing the spring 13 to deform. After the mounting ring 1 is assembled in the assembly ring plate 21, the positioning rod 12 is released. Under the action of the deformation force of the spring 13, the positioning rod 12 is pushed to insert into the plate seat 26.
