Description

Technical Field

[0001] The utility model relates to the technical field of laminated busbars, and more specifically, to a counterbore mold for a riveting machine. Background Art

[0002] With the development of industry, copper plate processing is widely used in many industries. Since the lap position with components requires the copper plate to be made into a convex shape to avoid insulation or other interferences, the method of riveting copper posts or welding copper sleeves is usually adopted to achieve this purpose.

[0003] In the above solution, the technical cost is high and the processing efficiency is low. With the increasing demand for copper plate processing, problems such as low efficiency and high cost will prolong the production cycle and increase the production cost. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a counterbore mold for a riveting machine that enables the copper plate to be formed in one step and achieves dimensional accuracy.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A counterbore mold for a riveting machine, including an upper die, a positioning pin and a lower die. The copper plate is placed between the upper die and the lower die. The positioning pin is connected to the lower die. Copper columns for connecting to the riveting machine are provided on the upper end surface of the upper die and the lower end surface of the lower die.

[0007] A positioning hole for the positioning pin to extend into is opened on the copper plate.

[0008] An annular boss is provided on the upper end surface of the lower die, and an installation hole for the positioning pin to extend into is opened in the middle of the annular boss.

[0009] An embedding groove for fitting with the annular boss and the positioning pin is opened on the lower end surface of the upper die.

[0010] The utility model is further provided as: The upper die and the lower die are made by heat treatment process.

[0011] The utility model is further provided as: A connecting column is provided on the positioning pin, threads are provided on the outer peripheral wall of the connecting column, threads are provided on the inner wall of the installation hole, and the positioning pin is connected to the lower die by threads.

[0012] Compared with the deficiencies of the prior art, the beneficial effects of the utility model are:

[0013] Through the precisely matched upper die and lower die, the one-time precise counterboring of the copper plate is achieved, greatly improving the production efficiency and the qualified rate of products. At the same time, through optimized design and material selection, the counterboring precision and efficiency are effectively improved, the service life of the die is extended, and the production cost is reduced. The method of processing the copper plate with this counterboring die has lower cost and higher efficiency compared with copper columns. It relatively enhances the electrical conductivity of the copper plate, has better lap joint with components, and better meets the needs of customers. Description of the Drawings

[0020] As Figures 1 to 3 shown,

[0021] The counterboring die for a riveting machine includes an upper die 1, a positioning pin 2 and a lower die 3. The copper plate 4 is placed between the upper die 1 and the lower die 3. The positioning pin 2 is connected to the lower die 3. The upper die 1 and the lower die 3 are made by heat treatment process, having excellent wear resistance and toughness, and can maintain high-precision performance for a long time in high-strength and high-frequency counterboring operations.

[0022] Copper columns 5 connected to the riveting machine are provided on the upper end surfaces of the upper die 1 and the lower end surfaces of the lower die 3. Positioning holes 6 for the positioning pins 2 to extend into are formed in the copper plate 4, which is used for the lower die 3 to accurately position the copper plate 4.

[0023] An annular boss 7 is provided on the upper end surface of the lower die 3. An installation hole 8 for the positioning pin 2 to extend into is formed in the middle of the annular boss 7. A connecting column 10 is provided on the positioning pin 2. Threads are formed on the outer peripheral wall of the connecting column 10 and on the inner wall of the installation hole 8. The positioning pin 2 and the lower die 3 are connected by threads, which is convenient for replacing the positioning pin 2 with a suitable size according to the differences of different copper plates 4 and the positioning holes 6 on the copper plate 4 as required.

[0024] An embedding groove 9 that fits with the annular boss 7 and the positioning pin 2 is formed on the lower end surface of the upper die 1. Through the pressure of the riveting machine, the copper plate 4 is embedded into the embedding groove 9, causing the copper plate 4 to deform, so as to realize the counterbore setting for the copper plate 4.

[0025] Working principle: When in use, install the positioning pin 2 with a suitable size on the appropriate lower die 3, and install the lower die 3 and the corresponding upper die 1 on the riveting machine. Then place the copper plate 4 to be processed between the upper die 1 and the lower die 3, and make the positioning pin 2 cooperate with the positioning hole 6. Then drive the riveting machine to press the upper die 1 downward, so that the lower die 3 presses the copper plate 4 into shape. The place where the copper plate 4 is stressed by the lower die 3 is embedded into the embedding groove 9, and a counterbore is pressed out on the copper plate 4. At this time, the processing of the copper plate 4 is completed. Take out the copper plate 4 and put another unprocessed copper plate 4 in, and repeat the above operation.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
