Description

Technical Field

[0001] This utility model relates to the field of cold drawing technology of steel wire, and in particular to a high-speed precision cold drawing forming machine for steel wire. Background Technology

[0002] The high-speed precision steel wire cold drawing forming unit is a professional equipment used to form steel wire with high precision and high efficiency through cold working process. It is mainly used to produce steel wire products with high precision, high strength and excellent surface finish.

[0003] Existing cold drawing forming units for steel wires install multiple cold drawing dies on the unit, allowing the steel bar to gradually reduce its diameter through multiple dies, thereby achieving precise reduction of the steel wire diameter. This helps improve the processing accuracy of the steel wire and ensures that the steel wire size is uniform and consistent.

[0004] However, in practical applications, existing cold drawing forming units usually use spraying to cool and lubricate the cold drawing mold. However, this cooling method cannot allow the coolant to directly contact the working area of ​​the cold drawing mold, which can easily cause uneven heating and cooling of the mold, resulting in deformation of the working surface of the mold. This is not conducive to improving the processing accuracy of the cold drawing forming unit for steel wire.

[0005] Therefore, this application provides a high-speed precision steel wire cold drawing forming unit to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose a high-speed precision steel wire cold drawing forming unit.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed precision steel wire cold drawing forming unit, comprising a forming unit body, and further comprising:

[0008] A molding assembly is placed on top of the molding unit body. The molding assembly includes a cold drawing mold disposed on top of the molding unit body. A cooling groove is provided inside the cold drawing mold, and a guide plate is provided inside the cooling groove. The guide plate has a spiral structure.

[0009] A quick-release assembly is placed at one end of the forming assembly and is used to remove and install the cooling groove. The quick-release assembly includes a connecting plate connected to one end of the cold drawing mold, and a snap-fit ​​block is connected to the side of the connecting plate near the cold drawing mold.

[0010] Furthermore, a support plate is connected between the forming unit body and the cold drawing mold.

[0011] The beneficial effects of adopting the above-mentioned further solution are: using a combination of bolts and nuts to fix the cold drawing die to the support plate makes it easier to disassemble the entire cold drawing die, which helps to improve the replacement efficiency of the cold drawing die.

[0012] Furthermore, a slide rail is connected to the side of the molding unit body near the support plate, and the support plate is slidably connected to the molding unit body through the slide rail.

[0013] The advantages of adopting the above-mentioned further solution are: it facilitates the adjustment of the distance between each cold drawing die, which helps to improve the flexibility of cold drawing die installation.

[0014] Furthermore, a water outlet pipe is connected to one side of the cold drawing mold, and a water inlet pipe is connected to the other side of the cold drawing mold.

[0015] The beneficial effect of adopting the above-mentioned further solution is that connecting the outlet pipe and the inlet pipe to the external circulation system facilitates the recycling of coolant.

[0016] Furthermore, the diameter of the outlet pipe is smaller than the diameter of the inlet pipe.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it helps to improve the heat exchange efficiency between the coolant and the cold drawing die and the guide plate.

[0018] Furthermore, both ends of the cooling tank are connected to limit blocks, and the cooling tank is engaged with the cold drawing mold and the snap-fit ​​block through the limit blocks.

[0019] The beneficial effects of adopting the above-mentioned further solution are: fixing the guide plate inside the cooling tank, avoiding the guide plate angle deviation, and preventing the guide plate rotation from blocking the water outlet pipe and water inlet pipe.

[0020] Furthermore, an elastic sealing ring is fitted onto the snap-fit ​​block, and the elastic sealing ring snaps into the cold drawing mold and the snap-fit ​​block.

[0021] The beneficial effect of adopting the above-mentioned further solution is that forming a tortuous path between the cold-drawing die and the snap-fit ​​block is conducive to improving the waterproof effect of the snap-fit ​​block.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. By setting up forming components, an annular cooling groove is set inside the cold drawing die. Combined with externally sprayed coolant, synchronous cooling of the inside and outside of the die is achieved, ensuring uniform cooling of the cold drawing die and preventing deformation of the working area due to uneven heating and cooling. At the same time, the guide plate in the cooling groove guides the flow of coolant, extends the flow path of coolant in the groove, and makes it fully contact the inner wall of the die, improving heat exchange efficiency. The guide plate is made of high thermal conductivity material, which can quickly absorb the heat of the die and further enhance the heat dissipation effect, which helps to improve the cooling efficiency and processing accuracy of the cold drawing forming unit of steel wire.

[0024] 2. By setting up a quick-release component, the snap-fit ​​block is embedded in the cooling tank and works in conjunction with the connecting plate to seal the cooling tank and prevent coolant leakage. At the same time, it limits the guide plate in the cooling tank. When it is necessary to replace the guide plate or clean the cooling tank, the connecting plate and snap-fit ​​block are removed and the guide plate is taken out, which improves the efficiency of guide plate disassembly, assembly and maintenance.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-5 As shown, this utility model provides a technical solution: a high-speed precision steel wire cold drawing forming unit, including a forming unit body 1. The forming unit body 1 consists of a wire feeding device, a pretreatment system, a wire take-up device, a drive system, a cooling system, and a control system. The wire feeding device is used to release the original steel wire coil to ensure continuous feeding; the pretreatment system reduces drawing resistance and protects the die; the wire take-up device winds the finished steel wire into a coil to maintain stable tension; the drive system is usually driven by a high-speed motor to achieve stable tensile force output; the cooling system reduces the heat generated during drawing by spraying coolant; the control system is used to control various devices and systems to achieve automation, and also includes:

[0036] like Figures 1-3 As shown, the molding component 2 is placed on top of the molding unit body 1. The molding component 2 includes a cold drawing mold 21 set on top of the molding unit body 1. A cooling groove 22 is opened inside the cold drawing mold 21. A guide plate 23 is set inside the cooling groove 22. The guide plate 23 has a spiral structure.

[0037] like Figures 1-4As shown, the quick-release assembly 3 is placed at one end of the forming assembly 2 and is used for the removal and installation of the cooling tank 22. The quick-release assembly 3 includes a connecting plate 31 connected to one end of the cold drawing die 21. A snap-fit ​​block 32 is connected to the side of the connecting plate 31 near the cold drawing die 21. By opening an annular cooling tank 22 inside the cold drawing die 21, coolant is injected into the interior of the cooling tank 22. The coolant directly cools the working area of ​​the cold drawing die 21, and works in conjunction with the externally sprayed coolant to cool both the interior and exterior of the cold drawing die 21, ensuring uniform cooling of the cold drawing die 21 and preventing deformation of the working area of ​​the cold drawing die 21. At the same time, the guide plate 23 guides the coolant to flow inside the cooling tank 22, extending the flow path of the coolant in the cooling tank 22, increasing the contact time with the inner wall of the cold drawing die 21, improving heat exchange efficiency, and solving the problem of easy mold deformation. Uneven heating and cooling cause deformation of the working surface of the mold. Using a high thermal conductivity material to make the guide plate 23 absorbs heat from the cold drawing mold 21, improving heat dissipation efficiency and thus enhancing the processing accuracy and cooling efficiency of the cold drawing forming machine. A snap-fit ​​block 32 is welded to one side of the connecting plate 31, and the connecting plate 31 is then fixed to one side of the forming machine body 1 using screws. At this point, the snap-fit ​​block 32 snaps into the interior of the cooling tank 22. The snap-fit ​​block 32 and the connecting plate 31 work together to seal the cooling tank 22, preventing coolant leakage and blocking the guide plate 23 inside the cooling tank 22. Removing the connecting plate 31 and the snap-fit ​​block 32 facilitates the removal of the guide plate 23 from the inside of the cold drawing mold 21, making it easier to replace the guide plate 23 and clean the interior of the cooling tank 22. This improves the efficiency of disassembly, assembly, and maintenance of the guide plate 23, and maintains the stability of the cold drawing forming machine.

[0038] Furthermore, such as Figure 1 and Figure 4 As shown, a support plate 24 is connected between the forming unit body 1 and the cold drawing die 21. The cold drawing die 21 is fixed on the support plate 24 by using a combination of bolts and nuts, which makes it easy to disassemble the entire cold drawing die 21 and improves the replacement efficiency of the cold drawing die 21.

[0039] Furthermore, such as Figure 4 As shown, a slide rail 25 is connected to the side of the molding unit body 1 near the support plate 24. The support plate 24 is slidably connected to the molding unit body 1 through the slide rail 25. The slide rail 25 is installed on the molding unit body 1 by bolts. A groove matching the slide rail 25 is opened on the support plate 24. The support plate 24 drives the cold drawing die 21 to slide on the slide rail 25, which facilitates the adjustment of the distance between each cold drawing die 21 and improves the flexibility of the installation of the cold drawing die 21. The slide rail 25 is provided with mounting holes. Hex socket screws are installed in the mounting holes and on the support plate 24 to facilitate the fixing of the support plate 24.

[0040] Furthermore, such as Figure 2 As shown, a water outlet pipe 26 is connected to one side of the cold drawing mold 21, and a water inlet pipe 27 is connected to the other side of the cold drawing mold 21. By connecting the water outlet pipe 26 and the water inlet pipe 27 to the external circulation system, it is convenient to realize the recycling of coolant. At the same time, the water outlet pipe 26, the water inlet pipe 27 and the guide plate 23 are staggered to prevent the guide plate 23 from blocking the water outlet pipe 26 and the water inlet pipe 27.

[0041] Furthermore, such as Figure 5 As shown, the diameter of the outlet pipe 26 is smaller than that of the inlet pipe 27. By reducing the size of the outlet pipe 26, the residence time of the coolant in the spiral flow channel is increased, which is beneficial to improving the heat exchange efficiency between the coolant and the cold drawing die 21 and the guide plate 23.

[0042] Furthermore, such as Figure 2 As shown, both ends of the cooling tank 22 are connected to limit blocks 33. The cooling tank 22 is engaged with the cold drawing mold 21 and the snap-fit ​​block 32 through the limit blocks 33. By opening limit grooves on the cold drawing mold 21 and the snap-fit ​​block 32 that match the limit blocks 33, the limit blocks 33 are snapped into the inside of the limit grooves, and the guide plate 23 is fixed inside the cooling tank 22 to prevent the angle of the guide plate 23 from shifting and to prevent the guide plate 23 from rotating and blocking the water outlet pipe 26 and the water inlet pipe 27.

[0043] Furthermore, such as Figure 2 As shown, the snap-fit ​​block 32 is fitted with an elastic sealing ring 34. The elastic sealing ring 34 snaps into the cold drawing mold 21 and the snap-fit ​​block 32. By snapping the two elastic sealing rings 34 between the cold drawing mold 21 and the elastic sealing ring 34, the two elastic sealing rings 34 cooperate to form a tortuous path between the cold drawing mold 21 and the snap-fit ​​block 32, which helps to improve the waterproof effect of the snap-fit ​​block 32.

[0044] Working principle: such as Figures 1-5As shown, first, the support plate 24 is installed on the cold drawing die 21 using nuts and bolts. The support plate 24 is then pushed to slide on the slide rail 25. The position of each cold drawing die 21 on the slide rail 25 is adjusted. The support plate 24 is then fixed using hex socket screws. The control system's wire feeding and take-up devices are activated to move the wire on the forming unit body 1. The drive device is then activated to increase the stable tension on the wire. The pretreatment system lubricates the wire to reduce drawing resistance. Afterward, the wire passes through the processing hole on the cold drawing die 21, and the wire is drawn. The cooling system is activated to spray coolant to reduce the heat generated during drawing. Simultaneously, the control system... The circulation system is started, and the coolant is introduced into the cooling tank 22 through the inlet pipe 27. At this time, the snap-fit ​​block 32 and the elastic sealing ring 34 cooperate to seal the cooling tank 22 to prevent coolant leakage. The guide plate 23 guides the coolant to flow inside the cooling tank 22, prolongs the flow path of the coolant in the cooling tank 22, increases the contact time with the inner wall of the cold drawing die 21, improves the heat exchange efficiency, and prevents uneven heating of the die. Since the diameter of the outlet pipe 26 is smaller than the diameter of the inlet pipe 27, the residence time of the coolant in the spiral flow channel is increased, which is beneficial to improving the heat exchange efficiency between the coolant and the cold drawing die 21 and the guide plate 23.

[0045] When the molding unit body 1 is inspected after a long period of use, the screws on the connecting plate 31 are removed, the connecting plate 31 and the snap-fit ​​block 32 are removed, the limiting block 33 is separated from the limiting groove on the snap-fit ​​block 32, the guide plate 23 is removed from the inside of the cooling tank 22, the inside of the cooling tank 22 is cleaned and a new guide plate 23 is replaced, and then the connecting plate 31 and the snap-fit ​​block 32 are reinstalled on the cold drawing mold 21, and the limiting block 33 is snapped into the limiting groove to fix the guide plate 23.

[0046] 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. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
