Description

Technical Field

[0001] The utility model relates to the technical field of terminal processing, in particular to a precision terminal blanking die. Background Technique

[0002] Connectors are now widely used in various fields, and terminals are the main components for transmitting signals in connectors. Terminals are usually formed by stamping a metal strip through a stamping die. The main processing contents include blanking, bending, etc. The common structure of a blanking die is as follows: it includes a punch and a die holder that cooperate with each other. The shape of the upper side of the die holder is the same as the shape required to be formed after the terminal is blanked. When the punch presses down, the excess waste on the strip is cut off to complete the blanking. At the same time, terminals of various different widths need to be blanked according to functional requirements;

[0003] During the stamping process of the terminal, the metal cut surface at the punching position of the terminal is easily deformed under the influence of extrusion stress. Then, the edge of the terminal hole is deformed and embedded in the die hole groove, resulting in the inability to strip the terminal from the die. Manual stripping operation of the terminal is required, which is not only time-consuming and laborious, but also only by using tools to lift the terminal in the die groove. This method will also cause damage and even deformation to the surface of the terminal plate. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0025] A precision terminal blanking die includes a processing platform 3. Symmetrically fixed to the lower end face of the processing platform 3 are support bases 2, and symmetrically fixed to the upper end face of the processing platform 3 are fixed plates 1. At the upper side position between the two fixed plates 1, an installation plate 4 is fixed, and an oil cylinder 5 is fixed on the installation plate 4. Fixed between the two support bases 2 is a waste collection box 6;

[0026] Fixed to the middle of the upper end face of the processing platform 3 is a lower die 9, and above the lower die 9 is provided an upper die 11, and a stamping head is fixed to the lower end face of the upper die 11;

[0027] Horizontally opened on the upper end face of the lower die 9 is a placing groove 17, and at a position corresponding to the stamping head inside the placing groove 17 is opened a stamping hole 7;

[0028] The upper die 11 is fixed to the output end of the oil cylinder 5, and on both sides of the upper die 11 is provided a stabilizing structure, and inside the lower die 9 is provided a blanking structure.

[0029] Specifically, at a position corresponding to the stamping hole 7 on the upper end face of the processing platform 3 is opened a connecting groove 8, and the waste collection box 6 is communicated with the stamping hole 7 through the connecting groove 8. Hinged to one side of the waste collection box 6 is a sealing door.

[0030] Specifically, the stabilizing structure includes movable grooves 16 opened on both sides of the upper die 11. Inside the movable grooves 16 is movably connected a pressure rod 12, and the pressure rod 12 is designed in a T-shaped structure. The upper side of the pressure rod 12 is sleeved with a first spring 15, and one end of the first spring 15 is fixed to the pressure rod 12, and the other end is fixed to the upper end face of the upper die 11.

[0031] Specifically, a rubber pad 13 is glued to the bottom of the pressure rod 12, and an electromagnet 14 is embedded and connected to the upper side of the bottom displacement rubber pad 13 of the pressure rod 12. In a static state, the length of the pressure rod 12 is greater than the length of the punch head, so that the pressure rod 12 can first contact the terminal raw material plate 10 and press it to keep it stable. The design of the rubber pad 13 prevents the pressure rod 12 from squeezing the terminal raw material plate 10 and causing damage.

[0032] Specifically, the blanking structure includes a displacement groove 18 opened on the lower mold 9 at a position corresponding to the pressure rod 12, and a magnet block 19 is movably connected in the displacement groove 18, and a spring 20 is fixed between the magnet block 19 and the displacement groove 18.

[0033] Working principle: During operation, the user first places the terminal raw material plate 10 in the placement groove 17, and then the user operates the control device connected to the cylinder 5 controller through the outside world, drives the cylinder 5 to push the mounting plate 4 downward, and moves the upper mold 11 and the punch head downward, and then the pressure rod 12 first contacts the terminal raw material plate 10 in the placement groove 17, and then the cylinder 5 continues to push the mounting plate 4 downward, at this time the pressure rod 12 moves up in the movable groove 16 to stretch the spring 15, and contacts the terminal raw material plate 10 through the pressure rod 12, and squeezes to keep the terminal raw material plate 10 stable during processing, and then until the punch head cooperates with the punching hole 7 to punch the terminal raw material plate 10, the stamping waste enters the waste collection box 6 through the connecting groove 8 for storage, and a certain amount of it can be accumulated later and the sealed door can be opened to take it out, and when the stamping is completed , the oil cylinder 5 is reset, and the punch head is separated from the terminal raw material plate 10. At this time, the pressure rod 12 continues to press the terminal raw material plate 10 under the action of the spring movement. Since the pressure rod 12 has an electromagnet 14 built in, the magnetic pole of the lower end surface of the electromagnet 14 can be changed by controlling the current direction of the electromagnet 14. When the pressure rod 12 presses the terminal raw material plate 10, the electromagnet 14 is conductive and magnetically repels the magnet block 19 in the displacement groove 18. The magnet block 19 moves down in the displacement groove 18 to compress the spring 20. When the subsequent pressure rod 12 is separated from the terminal raw material plate 10, the electromagnet 14 is powered off at this time, and the magnet block 19 in the displacement groove 18 is instantly reset under the elastic action of the spring 20 and collides with the upper terminal raw material plate 10, generating a shock force, so that the terminal raw material plate 10 after stamping is separated from the stamping hole 7, which is convenient for the user to handle it.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
