Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, and in particular to a cold drawing forming machine for linear springs. Background Technology

[0002] Linear springs, with their excellent elastic properties and structural characteristics, are widely used in aerospace, automotive, precision instruments, and consumer electronics. Cold drawing, as the core process in linear spring production, involves drawing metal wire at room temperature, causing it to undergo plastic deformation in a mold to obtain the desired shape and size. This process not only significantly improves the strength and surface quality of the spring but also effectively controls its precision, making it a crucial step in producing high-quality linear springs.

[0003] In the existing technology, cold drawing forming machines are needed to process the shape and size of metal wires in the production process of linear springs, thereby improving the strength and quality of the subsequent linear springs. However, in the traditional cold drawing forming machine, due to its simple structure, it is impossible to effectively cool and lubricate the wire during the cold drawing process. As a result, the temperature of the wire and the cold drawing die will rise sharply during long-term use, which will accelerate the wear of the cold drawing die and seriously affect its service life. Utility Model Content

[0004] This utility model mainly provides a linear spring cold drawing forming machine that can cool and lubricate metal wires and cold drawing dies, thereby reducing wear on the cold drawing dies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a linear spring cold drawing forming machine, including a cooling mechanism, wherein a main body mechanism is provided on the top of the cooling mechanism;

[0006] The cooling mechanism includes a workbench with an installation groove on one side of its outer wall. A cooling box is fixedly installed at the bottom of the inner wall of the installation groove. A baffle is fixedly installed on the inner surface of the cooling box. A cooling pipe is provided on one side of the outer wall of the baffle. A cooling device is fixedly installed on the top of the cooling box, and the outer wall of the cooling device is fixedly connected to the outer wall of the cooling pipe. A circulation pump is fixedly installed on the top of the cooling box, and the outer wall of the circulation pump is fixedly connected to the outer wall of the cooling pipe. A delivery pipe is fixedly connected to one side of the outer wall of the cooling box. A delivery pump is fixedly installed at the bottom of the inner wall of the installation groove, and the outer wall of the delivery pump is fixedly connected to the outer wall of the delivery pipe.

[0007] Preferably, a filter box is fixedly installed at the bottom of the inner wall of the mounting groove, and the filter box is fixedly connected to the outer wall of the cooling box through a pipe. Multiple filter plates are movably inserted into the inner wall of the filter box, and a return pipe is fixedly connected to one side of the outer wall of the filter box. Under the action of the return pipe, the used lubricating oil can enter the filter box, and under the action of the filter plates, the metal debris mixed in the lubricating oil can be filtered and adsorbed, which greatly improves the lubrication effect of the subsequent lubricating oil.

[0008] Preferably, the main body includes a base plate, an mounting platform is fixedly installed on the bottom of the inner wall of the base plate, two fixing brackets are fixedly installed on the top of the mounting platform, a spray head is fixedly inserted into the inner surface of each of the two fixing brackets, two rubber scrapers are fixedly installed on one side of the outer wall of the mounting platform, two fixing grooves are opened on the outer wall of the mounting platform, fixing columns are threadedly connected to the inner surface of each of the two fixing grooves, and a mold body is provided on the inner surface of each of the two fixing columns. Under the action of the spray head, the cooled lubricating oil can be sprayed to adhere to the surface of the metal wire, thereby improving the lubrication effect of subsequent metal wire processing and playing a cooling role.

[0009] Preferably, each of the two mold bodies has two circular grooves on its outer surface wall, and each of the four circular grooves has a return spring on its inner surface wall. Each of the four circular grooves also has a limit rod on its inner surface wall, and one side of the outer wall of the limit rod is fixedly connected to the outer surface wall of the return spring. Under the action of the return spring and the limit rod, the mold body can be quickly disassembled or installed, improving the efficiency of disassembly and installation.

[0010] Preferably, the top of the base plate has three movable slots, and a movable frame is movably embedded between the inner walls of the three movable slots. A hydraulic rod is fixedly inserted into the inner wall of the movable frame, and a fixing plate is fixedly installed at the telescopic end of the hydraulic rod. Anti-slip pads are fixedly installed on one side of the outer wall of the fixing plate and one side of the inner wall of the movable frame. Under the action of the hydraulic rod, the fixing plate and the anti-slip pads, the metal wire can be effectively fixed, greatly improving the effect of cold drawing of the metal wire.

[0011] Preferably, a motor is fixedly installed on one side of the outer wall of the base plate, and a lead screw is movably inserted into the inner surface of one of the three movable slots. The outer surface of the lead screw is fixedly connected to the output end of the motor, and the outer surface of the lead screw is threadedly connected to the inner surface of the movable frame.

[0014] 1. In this utility model, the lubricating oil inside the cooling tank can be cooled and lowered by the action of the cooling device, circulating pump and cooling pipe. Then, the cooled lubricating oil is transported by the action of the delivery pump, delivery pipe and nozzle to adhere to the surface of the metal wire. This reduces the friction between the metal wire and the mold during the subsequent cold drawing process and absorbs the heat generated by friction, thereby cooling the metal wire and the mold. This avoids the problem of severe wear of the cold drawing mold due to excessive friction and high temperature, thus extending the service life of the cold drawing mold and improving the use effect of the equipment.

[0015] 2. In this utility model, after the lubricating oil completes the lubrication and cooling of the metal wire, it will pass through the return pipe into the filter box. Under the action of the filter plate, the mixed metal debris in the lubricating oil can be filtered and adsorbed, which improves the quality of the lubricating oil and makes it more effective in subsequent lubrication and cooling processes. Furthermore, under the action of the fixed column, the return spring and the limit rod, the mold body can be quickly installed and disassembled, making it easier to replace the mold and improving the work efficiency of the staff.

[0026] like Figure 2As shown: A filter box 12 is fixedly installed on the bottom of the inner wall of the mounting groove 111, and the filter box 12 is fixedly connected to the outer wall of the cooling box 13 through a pipe. Multiple filter plates 122 are movably inserted into the inner wall of the filter box 12. A return pipe 121 is fixedly connected to one side of the outer wall of the filter box 12. Under the action of the return pipe 121, the used lubricating oil can enter the filter box 12, and under the action of the filter plates 122, the metal debris mixed in the lubricating oil can be filtered and adsorbed, which greatly improves the lubrication effect of the subsequent lubricating oil.

[0027] like Figure 2 As shown: The main body 2 includes a base plate 21. An installation platform 22 is fixedly installed on the bottom of the inner wall of the base plate 21. Two fixing brackets 221 are fixedly installed on the top of the installation platform 22. Spray nozzles 222 are fixedly inserted into the inner surface of the two fixing brackets 221.

Fixing posts 231 are threadedly connected to the inner surface of the two fixing grooves 23. Mold bodies 232 are provided on the inner surface of the two fixing posts 231. Under the action of the spray nozzles 222, the cooled lubricating oil can be sprayed to adhere to the surface of the metal wire, thereby improving the lubrication effect of subsequent metal wire processing and playing a cooling role.

[0028] like Figure 2 As shown: Two circular grooves 233 are opened on the outer wall of each of the two mold bodies 232. A return spring 234 is provided on the inner wall of each of the four circular grooves 233. A limit rod 235 is provided on the inner wall of each of the four circular grooves 233. One side of the outer wall of the limit rod 235 is fixedly connected to the outer wall of the return spring 234. Under the action of the return spring 234 and the limit rod 235, the mold body 232 can be quickly disassembled or installed, improving the efficiency of disassembly and installation.

[0029] like Figure 2 As shown: The top of the base plate 21 has three movable slots 24. A movable frame 241 is movably embedded between the inner walls of the three movable slots 24. A hydraulic rod 242 is fixedly inserted into the inner wall of the movable frame 241. A fixing plate 243 is fixedly installed at the telescopic end of the hydraulic rod 242. Anti-slip pads 244 are fixedly installed on one side of the outer wall of the fixing plate 243 and one side of the inner wall of the movable frame 241. Under the action of the hydraulic rod 242, the fixing plate 243 and the anti-slip pads 244, the metal wire can be effectively fixed, which greatly improves the effect of cold drawing of the metal wire.

[0030] like Figure 2As shown: A motor 25 is fixedly installed on one side of the outer wall of the base plate 21. A lead screw 251 is movably inserted into the inner surface of one of the three movable slots 24. The outer surface of the lead screw 251 is fixedly connected to the output end of the motor 25. The outer surface of the lead screw 251 is connected to the inner surface of the movable frame 241 by a thread. The motor 25 serves as a power source, which can drive the lead screw 251 to rotate and drive the movable frame 241 to move inside the movable slot 24. Since the motor 25 and the lead screw 251 are high-precision servo transmission systems, the accuracy of cold drawing of metal wire can be effectively improved.

[0031] like Figure 2 As shown: the top of the workbench 11 is fixedly connected to the bottom of the base plate 21, the outer wall of the return pipe 121 is fixedly connected to the outer wall of the base plate 21, and the outer wall of the delivery pipe 135 is fixedly connected to the outer wall of the nozzle 222. The above structure can connect the entire equipment, making the equipment a complete whole and enabling the equipment to operate normally.

[0032] The usage and working principle of this device are as follows: During the production and processing of linear springs, the cold drawing die is first replaced according to the required dimensions under the operation of the operator. The fixing post 231 is rotated out from the fixing groove 23. Then, by pressing the limiting rod 235, it is no longer used to fix the die body 232, and it is removed from the fixing post 231. Then, the appropriate die body 232 is inserted into the fixing post 231. At the same time, under the action of the return spring 234 and the limiting rod 235, it is fixed and limited. Finally, the fixing post 231 is inserted into the fixing groove 23 and fixed by the thread. Then, the metal wire is passed through the cold drawing die by external equipment, so that one end reaches between the inner wall of the fixed plate 243 and the movable frame 241. The fixed plate 243 is moved downwards by the hydraulic rod 242 to clamp and fix one end of the metal wire. The anti-slip pad 244 prevents the metal wire from falling off during subsequent stretching, greatly improving the subsequent processing effect. After the metal wire is fixed, the cooling water inside the cooling pipe 132 is circulated by the circulating pump 134 to cool the lubricating oil inside the cooling tank 13. The cooling device 133, with its internal fan and semiconductor heat dissipation device, cools the water, allowing it to continuously cool the lubricating oil inside the cooling tank 13 for an extended period. Once the lubricating oil has cooled, it is sprayed onto the surface of the metal wire by the pump 14, the delivery pipe 135, and the nozzle 222. Then, the motor 25 rotates the lead screw 251, causing the movable frame 241 to move within the movable slot 24, thus pulling the metal wire. Simultaneously, the metal wire is cold-drawn with the aid of the cold-drawing die. During this process, the lubricating oil... The bottom plate 21 can effectively reduce the friction between the metal wire and the cold drawing die, and also cool it down, reducing the wear of the cold drawing die and extending its service life. After the metal wire is cold drawn, the rubber scraper 223 can scrape off the excess lubricating oil on the surface of the metal wire. The used lubricating oil will enter the filter box 12 through the return pipe 121 into the square groove opened at the top of the bottom plate 21. Under the action of the filter plate 122, the metal chips and impurities mixed in the lubricating oil can be filtered to improve the quality of the lubricating oil. Finally, it enters the cooling box 13 for further cooling and cooling, realizing recycling.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
