[0002] Cold rolling dies include cold stamping dies, wire drawing dies, drawing dies, embossing dies, thread rolling dies, thread rolling plates, cold heading dies and cold extrusion dies, etc. Nickel plate processing technology refers to the process of processing nickel plates to achieve specific shapes, sizes and surface quality requirements. Cold stamping is to cold-deform nickel plates into the required geometric shapes through dies. This method can manufacture complex and precise parts. Existing cold rolling dies mostly use the lower die to fix, and the upper die to move up and down to stamp the product. The upper die needs to move at a higher speed and maintain a higher impact force. The product after cold rolling is easily embedded in the cavity of the lower die, which is not convenient for demolding.

[0003] In view of this, the present utility model is proposed. Utility Model Content

The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] like Figures 1 to 4 As shown, the electrolytic nickel plate cold rolling die comprises a lower die seat 1, an upper die seat 2, a pipe joint 18 and a main vent hole 19, a lower die model 3 is installed in the lower die seat 1, an installation chamber 15 is opened on the lower die seat 1 below the lower die model 3, an air pump 16 is installed in the installation chamber 15, an air outlet end of the air pump 16 is connected to an air supply pipe 17, an upper end of the air supply pipe 17 is connected to a pipe connector 18, an upper end of the pipe joint 18 is connected to the main vent hole 19, and a gas supply pipe 17 is connected to the main vent hole 19 in the lower die model 3. There are multiple ventilation branches 20, which extend into the model cavity 9. An upper mold model 4 matching the lower mold model 3 is installed on the upper mold base 2. A heating cavity 10 is arranged above the upper mold model 4. A heating rod 11 is installed in the heating cavity 10. A heat conducting plate 12 is arranged at the contact position between the heating cavity 10 and the upper mold model 4. A lower lifting power device 8 is arranged below the lower mold base 1, and an upper lifting power device 7 is arranged above the upper mold base 2, so that both the upper mold base 2 and the lower mold base 1 can be lifted and moved.

[0023] Among them, upper movable sliding ears 5 are symmetrically arranged on both sides of the upper mold base 2. The upper movable sliding ears 5 are processed with sliding matching holes, and upper guide pillars 13 are matched and installed in the matching holes of the upper movable sliding ears 5.

[0024] The lower mold base 1 is symmetrically provided with lower movable sliding ears 6 corresponding to the positions of the upper movable sliding ears 5 on both sides. The lower movable sliding ears 6 are processed with sliding matching holes. The matching holes of the lower movable sliding ears 6 are installed with lower guide pillars 14. The upper guide pillars 13 and the lower guide pillars 14 are split structures and are respectively installed on the body of the cold rolling mill at corresponding positions.

[0025] Both end positions of the upper mold model 4 and the lower mold model 3 are processed with mounting countersunk holes, and positions corresponding to the mounting countersunk holes are processed on the upper mold base 2 and the lower mold base 1. Fixing screws 21 are installed in the mounting countersunk holes and the threaded holes for mounting the upper mold model 4 on the upper mold base 2 and mounting the lower mold model 3 on the lower mold base 1.

[0026] The fixing screw 21 is a hexagonal countersunk screw, and a plurality of ventilation branches 20 are provided. Each ventilation branch hole 20 is a microporous structure, which can achieve rapid demoulding while ensuring the cold-rolled quality of the product.

[0027] The working principle of the utility model is as follows: when the cold rolling die is used for cold rolling of the electrolytic nickel plate, the electrolytic nickel plate is placed in the mold cavity 9 of the lower mold model 3, and a placement table is provided at the edge of the mold cavity 9 to facilitate the placement and positioning of the electrolytic nickel plate.

[0029] The novel structure used in the present invention is reasonably designed and easy to install and use. An upper lifting power device 7 is arranged on the upper mold seat 2, and a lower lifting power device 8 is arranged below the lower mold seat 1. The upper mold seat 2 and the lower mold seat 1 can move toward each other during the stamping process, which can effectively improve the relative speed and ensure the impact force requirement of the stamping process. An air pump 16 is arranged in the lower mold seat 1, and a ventilation branch hole 20 is opened on the lower mold model 3. The ventilation branch hole 20 is a microporous structure, which can achieve rapid demoulding while ensuring the cold rolling quality of the product. A heating chamber 10 is arranged in the upper mold seat 2 to perform temperature compensation during the cold rolling process and reduce the probability of work hardening.
