Description

Technical Field

[0001] The invention relates to the technical field of upper contact production, and in particular to a forming, processing and bending device for special-shaped copper upper contacts. Background Art

[0002] The upper contact is a part that is often used in the electrical field. When the upper contact is formed, it needs to go through the processing steps of cutting, bending, forging, trimming, etc. When the blank is bent, bending equipment is needed;

[0003] It is found that the existing bending equipment does not have a cooling function when in use. Since there is sliding friction between the bending head and the blank when bending the blank, the temperature of the bending head itself will rise when bending for a long time. Since there is no cooling function, the temperature of the bending head itself cannot be reduced, which affects the service life. In addition, the existing bending equipment does not have the function of preheating the blank, and the stress of the blank itself cannot be released. The blank will split during bending, so it needs to be improved.

[0004] Therefore, it is necessary to invent a special-shaped copper upper contact forming and bending equipment. Summary of the invention

Then, after the end, the hydraulic cylinder 4 is controlled to move the moving plate 5 and the bending head 6 upward and reset, and then the bent copper bar 17 can be taken out manually, and then the copper bar 17 can be placed on the support rod 16 according to the same principle to continue the bending work;

[0065] When bending, the temperature of the bending head 6 itself will rise. At this time, the pump body 1 9 is controlled to work, and then the coolant in the water tank 7 can flow through the empty slot under the action of the pipe 2 12, the pipe 1 11, the two hoses 10 and the pipe 3 13. After the coolant flows through, the heat of the bending head 6 itself can be taken away, thereby achieving a liquid cooling effect on the bending head 6. The temperature of the coolant itself will rise when it absorbs heat, and then the refrigeration plate 8 can be controlled to work, so that the coolant can be cooled, thereby preventing the coolant temperature from rising;

[0066] When the hydraulic cylinder 4 works to move the moving plate 5 and the bending head 6 up and down, the moving rod 39 and the piston 38 can also move up and down. When the moving rod 39 and the piston 38 move downward, the outside air can enter the box body 37 through the one-way valve 2 41. When moving upward, the air in the box body 37 can enter the two pipes 4 35 through the two pipes 5 40 and flow out from the through hole. How to circulate can continuously fill the water tank 7 with air, so that bubbles are generated in the coolant, and then the coolant rolls, so that the coolant can be kept in a stable state. To ensure that the coolant is cooled evenly and thoroughly, when the motor 45 rotates forward to move the base block 48 and other components forward, the two base blocks 48 will contact the two control switches 43. Since the two control switches 43 are electrically connected to the two solenoid valves 42 respectively, after contacting the two control switches 43, the two control switches 43 can control one solenoid valve 42 to open and the other to close, so that the air in the box body 37 can flow out from the through holes on the two pipes 435 in turn, so that bubbles are generated from the front side of the water tank 7 and the back side of the water tank 7;

[0067] When the motor 45 rotates forward to move the two base blocks 48 forward, the pull rod 58 and the protrusion 59 can also be moved forward. Since the protrusion 59 is embedded in the spiral groove 57, when the protrusion 59 moves forward, the shaft 1 52 can be rotated, and the rotation of the shaft 1 52 drives the bevel gear 1 55 to rotate, and the rotation of the bevel gear 1 55 drives the bevel gear 2 56 to rotate, and the rotation of the bevel gear 2 56 drives the shaft 2 53 to rotate, and the rotation of the shaft 2 53 drives the bevel gear 3 64 to rotate, and the rotation of the bevel gear 3 64 drives the bevel gear 4 65 to rotate, and the rotation of the bevel gear 4 65 drives the reciprocating screw 61 to rotate, and the rotation of the reciprocating screw 61 drives the sliding seat 62 and the atomizing nozzle 26 to move left and right continuously, so that the copper bar 17 is placed on the forming mold 2 When the copper bar 17 is placed on the forming mold 2, the atomizing nozzle 26 can be made to move left and right continuously. At this time, the pump body 25 can also be controlled to work. Then, under the action of the bellows 27, the lubricating oil can enter the atomizing nozzle 26 and be sprayed on the surface of the copper bar 17 from the atomizing nozzle 26, thereby realizing the spraying of lubricating oil on the surface of the copper bar 17 when the copper bar 17 is placed on the forming mold 2. In this way, the friction between the bending head 6 and the copper bar 17 can be reduced during bending, thereby reducing the loss. The bevel gear 2 56 is connected to the rotating shaft 2 53 through a one-way bearing, so when the motor 45 is reversed to move the base block 48 and other components backward to reset, the rotating shaft 2 53 will not rotate, thereby avoiding the reciprocating screw 61 from rotating when the base block 48 and other components are reset.

Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
