Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold drawing machine technology, specifically to a high-efficiency lubrication and cooling device for cold drawing wire machines. Background Technology
[0002] A cold drawing machine for steel pipe processing is a specialized piece of equipment used in steel pipe manufacturing. It shapes, stretches, and processes steel pipes through cold working methods. It is a highly efficient, precise, and energy-saving steel pipe manufacturing device. The working principle of the cold drawing machine is as follows: the steel pipe to be processed is fixed on the worktable, and then the rollers driven by the main shaft are used for cold drawing, thereby compressing the outer and inner diameters of the steel pipe to achieve the required specifications and precision. Cold drawing machines are usually equipped with a cooling system, which can control the material and hardness of the steel pipe, ensuring stable quality of the processed steel pipe. It is suitable for manufacturing high-precision, high-strength, and high-quality steel pipe products.
[0003] Patent CN117798205A discloses a cold drawing machine for steel pipe processing. This invention includes a cold drawing machine drive mechanism and a clamping mechanism, with the clamping mechanism positioned above the drive mechanism. It also includes a mandrel support mechanism, comprising several mandrel supports located on one side of the drive mechanism, each mandrel support including a mounting plate. This invention has a reasonable structure. The designed pipe-drawing stabilization mechanism ensures that the entire steel pipe is on the same axis during cold drawing, allowing for uniform force distribution and reducing the risk of damage from harsh pulling. The auxiliary template's compression of the steel pipe results in minimal deformation, effectively preheating the pipe. This preheating prevents radial runout caused by uneven temperature during subsequent cold drawing. Furthermore, its coordination with the drawing die head minimizes excessive external force deformation during cold drawing, thus preventing radial runout.
[0004] While the aforementioned invention can preheat the steel pipe to prevent radial runout caused by uneven temperature during subsequent cold drawing, the contact and extrusion process between the steel pipe and the cold drawing die generates a large amount of plastic deformation heat due to the metal's plastic deformation. Simultaneously, friction between the wire and the die also generates frictional heat, causing a rapid increase in the temperature of both the die and the wire. If the temperature is too high, the die may crack due to thermal fatigue, wear may accelerate, and the mechanical properties of the metal may be altered. Therefore, we propose a high-efficiency lubrication and cooling device for cold drawing machines. Utility Model Content
[0005] This invention provides a high-efficiency lubrication and cooling device for cold wire drawing machines to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high-efficiency lubrication and cooling device for a cold drawing wire machine includes a mounting base. Mounting brackets are provided at both ends of the rear side of the upper surface of the mounting base. A cold drawing mold is installed between two mounting brackets. A mounting mechanism is provided at the top of each mounting bracket. A cooling mechanism is inserted into the top of the mounting mechanism.
[0008] The cooling mechanism includes a connecting mechanism and a storage mechanism welded to the top of the connecting mechanism. The storage mechanism includes a storage tank and a top cover hinged to the upper right side of the storage tank. A liquid outlet pipe is installed in the middle of the lower front surface of the storage tank. A valve is installed on the outside of the liquid outlet pipe. A universal adjusting pipe is fixedly connected to the lower side of the liquid outlet pipe. A waste liquid cleaning port is installed on the lower right side surface of the storage tank. A feed inlet is provided on the left side of the upper surface of the top cover.
[0009] As a preferred technical solution, both the feed inlet and the waste liquid cleaning port are threadedly connected to end caps, and the outer surface of the end caps is provided with vertical anti-slip textures.
[0010] This feature allows both the feed inlet and the waste liquid cleaning inlet to be sealed with end caps when not in use, and the end cap on the upper feed inlet can also be used to assist in opening the upper cover.
[0011] As a preferred technical solution, the storage tank is composed of a cuboid portion at the top and a stepped structure that is wider at the top and narrower at the bottom. The liquid outlet pipe and the waste liquid cleaning port are both installed on the side surface of the stepped structure.
[0012] This design makes the bottom of the storage tank sloped, which facilitates the drainage of cooling lubricant.
[0013] As a preferred technical solution, each of the mounting brackets has a fixing block welded to the top left and right sides of its outer surface. The mounting mechanism includes a mounting block, two connecting grooves at the front and rear ends of the upper surface of the mounting block, and a snap-fit groove on the surface between the two mounting blocks. Fixing plates are welded to the lower left and right sides of the outer surface of the mounting block, and fixing bolts are connected between the fixing plates and the fixing blocks.
[0014] As a preferred technical solution, the mounting bracket has a U-shaped structure in its top view, and the size of the snap-fit groove is consistent with the internal empty groove of the mounting bracket.
[0015] As a preferred technical solution, the upper surface of the fixing block is provided with a threaded hole for the fixing bolt to be threadedly connected, and the upper surface of the fixing plate is provided with a through hole for the fixing bolt to pass through.
[0016] These three features allow the mounting mechanism to be easily installed on the upper side of the mounting bracket without affecting the cold drawing die.
[0017] As a preferred technical solution, the connecting mechanism includes a connecting plate and connecting rods welded to the four corners of the lower surface of the connecting plate, wherein the connecting rods correspond to the positions of the connecting grooves.
[0018] This design allows the connecting plate to be fixed in the connecting slot via the connecting rod and thus installed on top of the mounting block. The plug-in connection facilitates disassembly.
[0019] As a preferred technical solution, a rubber anti-slip sheet is attached to the lowest end of the inner side surface of the connecting groove. After the connecting rod is inserted into the lowest end of the connecting groove, it contacts the rubber anti-slip sheet and generates friction.
[0020] This feature ensures that the connector rod, once inserted into the bottom of the connector slot, can be secured by the friction generated with the rubber anti-slip plate.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. By installing a cooling mechanism on the upper side of the pipe where cold working is performed, and storing lubricating coolant in the storage tank, the heat generated by the plastic deformation of the metal at the cold working position can be dissipated during the cold working process, preventing the temperature from being too high and causing the mold to crack due to thermal fatigue.
[0023] 2. The cooling mechanism is inserted into the upper side of the mounting mechanism, which is fixed to the top of the mounting frame with bolts. When it is necessary to replace the cold drawing mold, the cooling mechanism and the mounting mechanism can be easily removed, making the operation convenient and quick. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0032] Please see Figures 1-5 This embodiment provides a technical solution:
[0033] A high-efficiency lubrication and cooling device for a cold drawing wire machine includes a mounting base 100. Mounting brackets 300 are provided on both the left and right ends of the rear side of the upper surface of the mounting base 100. A cold drawing mold 200 is installed between the two mounting brackets 300. A mounting mechanism 400 is provided at the top of each mounting bracket 300. A cooling mechanism 500 is inserted into the top of the mounting mechanism 400.
[0034] The cooling mechanism 500 includes a connecting mechanism 510 and a storage mechanism 520 welded to the top of the connecting mechanism 510. The storage mechanism 520 includes a storage tank 521 and a top cover 522 hinged to the upper right side of the storage tank 521. A liquid outlet pipe 525 is installed in the middle of the lower front surface of the storage tank 521. A valve 526 is installed on the outside of the liquid outlet pipe 525. A universal adjusting pipe 527 is fixedly connected to the lower side of the liquid outlet pipe 525. A waste liquid cleaning port 524 is installed on the lower right side surface of the storage tank 521. A feed inlet 523 is provided on the left side of the upper surface of the top cover 522.
[0035] Furthermore, such as Figure 3 As shown, both the feed inlet 523 and the waste liquid cleaning inlet 524 are threaded with end caps. The outer surface of the end caps has vertical anti-slip textures to increase the friction between the user and the side surface of the end caps.
[0036] Furthermore, such as Figure 5As shown, the storage tank 521 consists of a cuboid section at the top and a stepped structure that is wider at the top and narrower at the bottom. The liquid outlet pipe 525 and the waste liquid cleaning port 524 are both installed on the side surface of the stepped structure. The lower surface of the liquid outlet pipe 525 and the waste liquid cleaning port 524 are in contact with the lower surface of the inside of the storage tank 521.
[0037] In this embodiment, as Figure 2 As shown, each mounting bracket 300 has a fixing block 310 welded to the top left and right sides of its outer surface. The mounting mechanism 400 includes the mounting block 410, two connecting grooves 420 opened at the front and rear ends of the upper surface of the mounting block 410, and a snap-fit groove 430 opened on the surface between the two mounting blocks 410. The fixing plates 450 are welded to the lower left and right sides of the outer surface of the mounting block 410. The fixing plates 450 and the fixing blocks 310 are connected by fixing bolts 440. The mounting bracket 300 has a U-shaped structure in its top view. The size of the snap-fit groove 430 is consistent with the internal empty groove of the mounting bracket 300, which facilitates the installation of the cold drawing mold 200 in the mounting bracket 300. The upper surface of the fixing block 310 has a threaded hole for the fixing bolt 440 to be threaded. The upper surface of the fixing plate 450 has a through hole for the fixing bolt 440 to pass through. The fixing bolt 440 is threadedly connected in the fixing block 310 to fix the fixing plate 450 to the upper side of the fixing block 310.
[0038] In this embodiment, as Figure 4 As shown, the connecting mechanism 510 includes a connecting plate 511 and connecting rods 512 welded to the four corners of the lower surface of the connecting plate 511. The connecting rods 512 correspond to the positions of the connecting grooves 420, ensuring that the connecting plate 511 can be installed on the top of the mounting block 410 by inserting the connecting rods 512 into the connecting grooves 420. A rubber anti-slip sheet is attached to the lowest end of the inner side surface of the connecting groove 420. After the connecting rods 512 are inserted into the lowest end of the connecting groove 420, they contact the rubber anti-slip sheet and generate friction. The friction generated between the connecting rods 512 and the rubber anti-slip sheet fixes the connecting rods 512 inside the connecting groove 420.
[0039] It is worth noting that the structure and working principle of the valve 526 involved in this embodiment are as known to those skilled in the art, and will not be described in detail here. The structure and working principle of the mounting base 100 and the cold drawing mold 200 involved in this embodiment are technologies already disclosed in the prior art, and will not be described in detail here.
[0040] In the specific use of the high-efficiency lubrication and cooling device for the cold drawing machine in this embodiment, when the pipe enters the cold drawing mold 200 to undergo cold processing, it is necessary to adjust the position of the universal adjustment pipe 527 so that the outlet of the universal adjustment pipe 527 is aligned with the position of the pipe undergoing cold processing. Then, when the cold processing begins, the valve 526 at the top of the outlet pipe 525 is opened to transport the cooling and lubricating fluid stored in the storage tank 521 to the cold processing contact position through the universal adjustment pipe 527 to provide cooling and lubrication for the cold processing process.
[0041] When it is necessary to replace the cold drawing die 200, first hold the storage box 521 and pull the storage mechanism 520 upward, so that the connecting plate 511 moves upward and drives the connecting rod 512 away from the connecting groove 420. Then loosen the fixing bolt 440 and remove it. The mounting block 410 can be removed from the top of the mounting bracket 300. Then the cold drawing die 200 can be taken out for replacement.
[0042] After the storage box 521 is removed, the top cover 522 can be opened to clean the inside. After cleaning, the waste liquid generated can be discharged by opening the end cap connected to the external thread of the waste liquid cleaning port 524.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
