Description

Technical Field

[0001] The utility model relates to the technical field of stamping processing, in particular to a conductive connecting piece stamping and cleaning-free device. Background Art

[0002] Stamping is a forming process that uses a press and die to apply external force to sheet metal, strip, tube, and profiles, causing them to plastically deform or separate, thereby obtaining a workpiece (stamped part) of the desired shape and size. Stamping and forging are both types of plastic working (or pressure working), collectively known as forging. The blanks used for stamping are primarily hot-rolled and cold-rolled steel sheets and strips.

[0003] In the prior art, the Chinese utility model with publication number CN215088193U discloses a device for automatic oil spraying for feeding a punch press, comprising a distributor, an oil pipe, a pneumatic oil pump, an oil tank and an oil injection electromechanical box, wherein the distributor is connected to one end of the oil pipe, and the other end of the oil pipe is connected to the pneumatic oil pump, the pneumatic oil pump is provided with an electric air valve, the electric air valve inputs compressed air, the electric air valve is connected to the oil injection electromechanical box through a control cable, the oil injection electromechanical box is connected to the unwinding electromechanical box, and the pneumatic oil pump is also connected to the oil tank through an oil inlet pipe; the utility model automatically sprays stamping oil for the stamping material when the punch press continuously punches the die, adopts electronic control and pneumatic coordination to complete the uniform spraying of stamping oil, sprays a certain amount of stamping oil each time a product is stamped, and does not spray oil when there is no stamping, so as to prevent excessive oil consumption and waste.

[0004] In the above technical solution, the stamping oil is sprayed on the stamping material through the distributor using the oil nozzle before stamping, and then the stamping material is transported and stamped in sequence. The stamping oil here must have the characteristic of being locally non-volatile, otherwise the stamping oil will evaporate quickly during the transportation of the stamping material, resulting in the stamping oil being completely evaporated during the stamping stage and having no lubricating effect. However, if a non-volatile stamping oil is used here, the stamping parts need to be rinsed later to remove the stamping oil on the surface, which makes the processing and production of stamping parts complicated.

[0025] By moving the movable upper die base 2 downward, the delivery pipe 6 is driven to move downward, and the lower liquid outlet 9 and the upper liquid outlet 8 are connected to the infusion channel 10 in turn. Before the die base 3 and the die groove 4 stamp the stamping material, the infusion pipe sprays the stamping oil through the infusion channel 10 onto the surface of the stamping material, and then the stamping is carried out. When the movable upper die base 2 moves upward, the stamping oil evaporates quickly due to the heat generated by the stamping, and there is no need to subsequently clean the stamped parts, thereby reducing the stamping part processing process.

[0026] Support columns 11 are fixed around the top of the fixed lower die base 1, a fixed base 12 is fixed on the top of the support columns 11, and a hydraulic cylinder 13 is fixed at the center of the top of the fixed base 12. The piston rod of the hydraulic cylinder 13 passes through the fixed base 12 and is fixedly connected to the top of the movable upper die base 2. The fixed base 12 is fixedly supported by the support columns 11, and then the hydraulic cylinder 13 is used to drive the movable upper die base 2 to move up and down, which is convenient for stamping processing of stamping materials.

[0027] A first supporting spring 14 is fixed to the bottom of the inner cavity of the vertical hole 7, and the top of the first supporting spring 14 is fixedly connected to the bottom of the delivery tube 6. Two groups of limiting rings 15 are fixed to the outer side of the lower section of the delivery tube 6. One group of limiting rings 15 is located above the fixed lower die base 1, and the other group of limiting rings 15 is located in the inner cavity of the vertical hole 7. Through the cooperation of the first supporting spring 14, it is convenient to support the delivery tube 6 upward to prevent the lower liquid outlet 9 from being connected to the infusion channel 10 in the fixed lower die base 1. At the same time, through the setting of the two groups of limiting rings 15, it is convenient to limit the upward and downward distances of the delivery tube 6 to prevent the delivery tube 6 from moving out of the vertical hole 7 and the through hole 5, causing the upper liquid outlet 8 and the lower liquid outlet 9 to move out of the through hole 5 and the vertical hole 7, resulting in leakage of stamping oil.

[0028] A fixing ring 16 is fixed to the outer side of the upper section of the delivery tube 6, and the fixing ring 16 is located above the movable upper mold base 2. A second support spring 17 is sleeved on the outer side of the delivery tube 6. The two ends of the second support spring 17 are respectively fixedly connected to the fixing ring 16 and the movable upper mold base 2. The second support spring 17 is limited and supported by the fixing ring 16, which facilitates the downward pulling of the delivery tube 6 by the second support spring 17, and facilitates the communication between the lower liquid outlet 9 on the delivery tube 6 and the infusion channel 10.

[0029] Side baffles 18 are fixed on both sides of the bottom of the movable upper die base 2, and the side baffles 18 are located on the inner side of the conveying pipe 6. Side baffles 18 are fixed on both sides of the bottom of the movable upper die base 2, and the side baffles 18 are located on the inner side of the conveying pipe 6. The setting of the side baffles 18 can facilitate the transportation of the stamping material to avoid contact between the stamping material and the conveying pipe 6, which may cause damage and rupture of the conveying pipe 6.

[0030] Positioning columns 19 are fixed on both sides of the top of the fixed lower mold base 1, and positioning grooves 20 that are engaged with the positioning columns 19 are opened on both sides of the bottom of the movable upper mold base 2. The positioning columns 19 slide in the positioning grooves 20 to facilitate the positioning of the movable upper mold base 2 and the mold base 3 to prevent dislocation.

[0031] Punching columns 21 for punching are fixed on both sides of the top of the inner cavity of the die groove 4, and blanking holes 22 aligned with the punching columns 21 are opened on the fixed lower die base 1 and the die base 3. The setting of the punching columns 21 and the blanking holes 22 facilitates punching during the stamping and shaping stage of the conductive connecting piece.

[0032] The four groups of delivery pipes 6 extend upward and are connected to the delivery main pipe 23. A control valve 24 is installed on the delivery main pipe 23. The stamping oil is delivered to the delivery pipes 6 through the delivery main pipe 23, and the injection rate and size of the stamping oil are controlled by the control valve 24 to avoid waste caused by excessive stamping oil.

[0033] When in use, the hydraulic cylinder 13 drives the movable upper die base 2 to move downward, and then the movable upper die base 2 drives the delivery pipe 6 to move downward together through the cooperation of the second support spring 17 and the fixed ring 16. During the downward movement, the delivery pipe 6 squeezes the first support spring 14, so that the delivery pipe 6 moves in the vertical hole 7 and connects the lower liquid outlet 9 with the infusion channel 10. At this time, the stamping oil in the delivery pipe 6 flows from the lower liquid outlet 9 into the infusion channel 10 in the fixed lower die base 1, and finally is sprayed from the top of the die base 3 to the bottom of the stamping material. The seat 2 moves downward, and then the limiting ring 15 limits the delivery pipe 6. At this time, the movable upper die seat 2 stretches the second support spring 17 to connect the upper liquid outlet 8 with the infusion channel 10 in the movable upper die seat 2. Stamping oil is sprayed to the top of the stamping material through the infusion channel 10. Then the movable upper die seat 2 and the die seat 3 on the fixed lower die seat 1 stamp the stamping material. The sprayed stamping oil plays a lubricating role. When the movable upper die seat 2 moves upward and separates from the fixed lower die seat 1, the stamping oil is heated by the heat generated by stamping and evaporates quickly.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
