Description

Technical Field

[0001] The utility model relates to the field of xx, in particular to a continuous stamping die for producing fuse shrapnel. Background Art

[0002] A fuse clip is a hardware accessory used to protect circuits from overload or short circuit. It is commonly used in car charger hardware accessories, cigarette lighter metal accessories and other fields. Through its special structure and materials, it ensures that the circuit can be safely disconnected under abnormal circumstances, thereby protecting electrical equipment and lines from damage.

[0003] During the processing of existing fuse springs using a continuous stamping die, the die will frequently contact and rub against the fuse spring material, which can easily cause die wear and affect the stamping accuracy and the size of the spring. The existing method to avoid excessive die wear is to apply lubricating oil to the surface of the punch head, but this needs to be applied manually each time, which not only reduces work efficiency but also causes uneven lubrication due to uneven application force, which can easily cause local wear.

[0004] Therefore, a continuous stamping die for producing fuse springs is proposed. Utility Model Content

[0005] In view of the above problems, the present invention provides a continuous stamping die for producing fuse springs to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is:

[0007] The top surface of the upper die is fixed with a hydraulic cylinder to control the oil pump, and the bottom surface of the hydraulic cylinder is fixed with a hydraulic cylinder to adjust the pressure.

[0008] In a further technical solution, the outer surface of the oil outlet pan is circumferentially distributed with bumps, the bottom ends of the bumps are fixedly connected to a spring, the outer surface of the bottom end of the oil outlet pan is sleeved with a scraper frame, and the top surface of the scraper frame is fixedly connected to the bottom surface of the spring.

[0009] Through the above technical solution, when the oiling box contacts the oil outlet tray, the nozzle can spray oil to the sponge, and then when the oiling box leaves the oil outlet tray, the scraper frame can absorb excess oil to prevent it from dripping onto the surface of the workbench.

[0010] In a further technical solution, the rotating part includes a motor, the housing of the motor is fixed to the top surface of the upper mold base, the output end of the motor is fixedly connected to a rotating shaft, a bearing is inserted into the surface of the upper mold base, the outer surface of the rotating shaft is fixed to the inner wall of the bearing, and the bottom end of the rotating shaft is fixedly connected to a support plate, and the end of the support plate away from the rotating shaft is fixed to the side wall of the oiling box.

[0011] Through the above technical solution, the driving motor can make the oiling box rotate with the rotating shaft as the center, so that the oiling box absorbs the lubricating oil and then applies it when it contacts the die head.

[0012] In a further technical solution, a first inclined surface is provided on the top side of the oiling box, and a second inclined surface is provided on the bottom side of the scraping frame, and the second inclined surface is opposite to the first inclined surface, and the second inclined surface and the first inclined surface can be fitted and matched.

[0013] Through the above technical solution, when the oiling box rotates and is located below the oil outlet pan, the first inclined surface first contacts the second inclined surface on the bottom surface of the scraper frame. When the oiling box leaves the bottom of the oil outlet pan, the first inclined surface can make the oiling box easily detached from the bottom end of the scraper frame, avoiding jamming.

[0014] In a further technical solution, the middle portion of the surface of the first inclined surface is in contact with the bottom surface of the scraping frame on a side away from the second inclined surface.

[0015] Through the above technical solution, the setting of the structure makes the bottom end of the scraper frame actually located outside the top end of the oiling box. The spring can be used to push the squeezing spring upward when the oiling box is away from the scraper frame to achieve the separation of the oiling box and the scraper frame.

[0016] In a further technical solution, a transition opening is provided on the bottom surface of one side of the scraping frame on the support plate, and the opening width of the transition opening is greater than the width of the support plate.

[0017] The above technical solution facilitates adaptation to the state where the oiling box is located below the oil outlet tray.

[0018] In a further technical solution, the edge of the transition opening is an arc-shaped surface.

[0019] The above technical solution can also facilitate the oiling box to avoid getting stuck when it is away from the scraping frame.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By arranging an oiling box movable between the oil outlet pan and the bottom surface of the die head, the oiling box can receive lubricating liquid from the oil outlet pan and then apply it to the surface of the die head. The structure is simple and easy to operate, and can avoid the die head from being in contact with the fuse spring piece for a long time due to insufficient lubrication and wear. At the same time, there is no need for frequent manual oiling, which improves the convenience of processing the fuse spring piece with the stamping die. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom surface of the oil outlet pan 7 is connected with a nozzle 8, and a connecting pipe 6 is connected between the oil outlet pan 7 and the oil tank 5. An oiling box 13 is provided between the die head 4 and the oil outlet pan 7, and a groove 14 is provided on the top surface of the oiling box 13. A sponge 15 is fixedly connected to the inner wall of the groove 14. A rotating part is provided on the outer surface of the upper die base 2, and the oiling box 13 moves between the oil outlet pan 7 and the bottom surface of the die head 4 through the rotating part.

[0036] See also Figure 4 and Figure 7 The outer surface of the oil outlet pan 7 is circumferentially distributed with bumps 17, the bottom end of the bump 17 is fixedly connected to a spring 18, and the outer surface of the bottom end of the oil outlet pan 7 is sleeved with a scraper frame 16, and the top surface of the scraper frame 16 is fixedly connected to the bottom surface of the spring 18.

[0037] When the oiling box 13 contacts the oil outlet tray 7 , the nozzle 8 sprays oil to the sponge 15 , and then when the oiling box 13 leaves the oil outlet tray 7 , the scraper frame 16 absorbs excess oil to prevent it from dripping onto the surface of the workbench 1 .

[0038] See also Figure 2 and Figure 3 The rotating part includes a motor 9, the shell of the motor 9 is fixed to the top surface of the upper mold base 2, the output end of the motor 9 is fixedly connected to the rotating shaft 11, a bearing 10 is inserted into the surface of the upper mold base 2, the outer surface of the rotating shaft 11 is fixed to the inner wall of the bearing 10, and the bottom end of the rotating shaft 11 is fixedly connected to the support plate 12, and the end of the support plate 12 away from the rotating shaft 11 is fixed to the side wall of the oiling box 13.

[0039] The driving motor 9 can make the oiling box 13 rotate with the rotating shaft 11 as the center, so that the oiling box 13 absorbs the lubricating oil and then applies it when it contacts the die head 4.

[0040] See also Figure 5-Figure 7 A first inclined surface 19 is provided on the top side of the oiling box 13, and a second inclined surface 20 is provided on the bottom side of the scraping frame 16.
