Description

Technical Field

[0001] The present application relates to the field of tin bar wire drawing, and in particular to a roller wire drawing device with a circulating lubrication system. Background Art

[0002] Tin soldering rods and tin soldering wires are commonly used consumables in the welding process in industrial production. In the production process of tin soldering rods and tin soldering wires, the tin ingot is first melted into liquid and then made into thick tin rods, and then the tin rods are passed through a wire drawing die to make thin welding wires.

[0003] During the tin wire processing process, larger diameter tin bars are rolled into smaller diameter tin wires through a tin wire drawing machine. Existing tin wire drawing machines include multiple sets of rollers, through which the tin bars are squeezed and ultimately formed into tin wire. When the tensioning device pulls the tin bars, if the rollers don't immediately contact the cooling lubricant, friction can easily clog the inner grooves of the rollers, requiring manual intervention. However, the contact between the tin bars and the inner grooves is too close, making it difficult to apply the lubricant, making it inconvenient. Therefore, a spray method is used to replenish the cooling lubricant at the rollers to complete the cooling and lubrication process.

[0004] However, in the existing technology, after the cooling lubricant is sprayed out from the spray pipe, it falls into the waste tank together with the waste generated by pulling the tin bar, and the cooling lubricant cannot be recycled. During the long production process, the production cost increases and the economic benefit decreases. Utility Model Content

[0005] In order to facilitate the recycling of cooling lubricating fluid, a roller drawing device with a circulating lubrication system is provided.

[0006] The above-mentioned application objectives of this application are achieved through the following technical solutions:

[0007] A roller-drawing device with a circulating lubrication system includes a machine body and a roller group, and also includes a circulating lubrication system. The circulating lubrication system includes a spray pipe and a circulating main pipe. A storage tank, a recovery tank and a fixed tank are opened in the machine body. The storage tank is located below the spray pipe. The storage tank has a recovery port, which is connected to the recovery tank. A booster pump is installed in the fixed tank, and the booster pump is connected to the circulating main pipe.

[0008] By adopting the above technical solution, since the tin bar produces less oxides and debris during the rolling process, the lubricating fluid is easy to filter during recovery and can be easily recovered. The device of the present application directly establishes a circulating lubrication system, and the cooling lubricating fluid is collected, filtered, and simply settled at the recovery port before flowing into the recovery tank, and then transported by the booster pump to the circulation main pipe for recycling. Due to the recycling of the cooling lubricating fluid, the total amount of lubricating fluid during equipment working hours is reduced, the loss of lubricating fluid during evaporation is reduced, and the actual production cost is reduced.

[0009] Optionally, the number of the spray pipes is equal to the number of the pressure roller groups, and the spray pipes are located on the sides of the pressure rollers.

[0010] By adopting the above technical solution, since friction is generated when the pressure rollers pull and extrude the tin bar, a spray pipe is provided on the side of each group of pressure rollers to prevent the tin bar from being blocked in the pressure groove of a certain pressure roller group and affecting the breakage of the entire tin bar.

[0011] Optionally, a spray hole facing the pressure roller group is opened at the spray head of the spray pipe, and a filter screen is installed on the spray hole.

[0012] By adopting the above technical solution and setting up a filtering net, the cooling lubricating liquid sprayed from the spray hole can be filtered and can evenly contact the pressure roller group, achieving a better spraying effect and reducing the splashing of the cooling lubricating liquid when it contacts the pressure roller group.

[0013] Optionally, separate one-way valves are provided at the connections between the circulation main pipe and the spray pipe.

[0014] By adopting the above technical solution, due to the different product properties of tin soldering wire and different types of flux, the roller group and roller speed will be adjusted during rolling. The heating conditions of the tin bar during corresponding rolling are different. For this purpose, a separate one-way valve is set to facilitate the regulation of the cooling lubricating liquid injection amount of each spray pipe.

[0015] Optionally, a filter bottom is installed on the surface of the recovery port.

[0016] By adopting the above technical solution, tin powder and debris will fall off the tin bar after being squeezed by the pressing groove of the pressing roller, and a filter bottom is provided to filter the tin powder and debris in the cooling lubricating liquid.

[0017] Optionally, a baffle is also installed on the side of the accumulation tank.

[0018] By adopting the above technical solution, since the accumulation tank below the spray pipe is shallow, splashing of the cooling lubricating liquid when spraying toward the pressure roller is avoided.

[0019] Optionally, a limiting groove is further provided on the machine body, and the baffle is clamped in the limiting groove.

[0020] Through the above technical solution, the baffle is clamped in the limit groove on the body, and the baffle is easy to disassemble and assemble, which makes it convenient for operators to clean the tin powder and debris in the accumulation tank during maintenance.

[0021] Optionally, the machine body includes a feed conduit and a discharge conduit, and both the feed conduit and the discharge conduit pass through the baffle.

[0022] By adopting the above technical solution, the pulling direction of the incoming tin bars and the outgoing tin wire is constrained, which not only facilitates the feeding and discharging of materials and stabilizes the rolling process, but also prevents the tight tin bars and tin wire from being directly thrown up due to breakage during the rolling process and injuring workers.

[0023] In summary, this application has at least the following beneficial effects:

[0024] 1. Establish a cooling lubricant circulation system. The cooling lubricant is collected from the recovery port, flows into the recovery tank after simple sedimentation, and is then transported to the circulation main pipe by the booster pump for recycling. In addition, due to the recycling of the lubricant, the total amount of lubricant during equipment working hours is reduced, the lubricant volatilization loss is reduced, and the actual production cost is reduced.

[0025] 2. Because the accumulation tank below the spray pipe is shallow, a detachable baffle is set to prevent the cooling lubricant from splashing when spraying onto the pressure roller, and to facilitate the cleaning of tin powder in the accumulation tank during maintenance.

[0032] The following is a further detailed description with reference to the accompanying drawings:

[0033] As attached Figure 1As shown, the roller drawing device with a circulating lubrication system includes a machine body 1, a roller group 2 and a circulating lubrication system 3.

[0034] As attached Figure 2 As shown, the roller group 2 includes two rollers 21, which are arranged in sequence on the surface of the machine body 1. The roller group 2 is rotatably connected to the machine body 1, and the rollers 21 in the same group are placed in the same direction, while the rollers 21 in adjacent groups are placed in perpendicular directions. The circumferential side surfaces of the rollers 21 are also provided with semicircular grooves 211. The grooves 211 on the rollers 21 in the same group are of the same size, and gradually decrease from the tin bar feeding side to the discharge side. At the same time, the speeds of the rollers 21 in different groups also vary, increasing step by step from the tin bar feeding side to the discharge side. As a result, due to the combined effects of the pulling force caused by the different speeds between the roller groups 2 and the extrusion force caused by the differences in the grooves 211 between the roller groups 2, the tin bars are pulled and squeezed thinner as they pass through the roller group 2, ultimately forming tin wire.

[0035] As attached Figure 2 and attached Figure 3 As shown, the circulating lubrication system 3 includes a circulating main pipe 31 , a spray pipe 32 , a one-way valve 33 and a booster pump 34 .

[0036] The spray pipe 32 is connected to the circulation main pipe 31, and a one-way valve 33 is installed at the connection. Due to the different product properties of the tin soldering wire and the different types of flux, the speed of the roller group 2 will be adjusted during rolling. The heating conditions of the tin bar during corresponding rolling are different. Therefore, a separate one-way valve 33 is installed at the connection between each spray pipe 32 and the circulation main pipe 31, which can conveniently regulate the amount of cooling lubricating liquid sprayed by each spray pipe 32.

[0037] As attached Figure 3 and attached Figure 4 As shown, the number of spray pipes 32 is equal to the number of pressure roller groups 2. The spray pipes 32 are located on the side of the pressure roller group 2. Spray holes 321 facing the pressure roller group 2 are also opened on the spray pipes 32. The spray holes 321 are aligned with the center point of the same pressure roller group 2. When the tin bar is pulled and squeezed by the pressure roller 21 and transported forward, cooling lubricating liquid is sprayed to reduce the temperature and friction between the pressure roller 21 and the tin bar.

[0038] A filter net 322 is installed on the spray hole 321. The filter net can filter the cooling lubricating liquid sprayed from the spray hole 321, so that it can evenly contact the pressure roller group 2, achieve a better spraying effect, and reduce the splashing of the cooling lubricating liquid when it contacts the pressure roller group 2.

[0039] As attached Figure 2 and attached Figure 3As shown, a storage tank 11 is also provided on the machine body 1, and the storage tank 11 is located below the pressure roller group 2 on the surface of the machine body 1. When the spray pipe 32 sprays cooling lubricant on the pressure roller 21, the lubricant on the surface of the pressure roller 21 after lubrication and cooling will flow down into the storage tank 11, and excess cooling lubricant will also be stored in the storage tank 11. At the same time, the tin powder or debris liquid generated by the pressure roller group 2 when pulling and squeezing the tin bar falls into the storage tank 11; a recovery port 111 is also provided at the bottom of the storage tank 11, and the bottom of the storage tank 11 is an inclined surface, and the side away from the recovery port 111 is higher than the side close to the recovery port 111, and the cooling lubricant in the storage tank 11 flows into the recovery port 111.

[0040] A recovery tank 16 is also provided in the machine body 1. The recovery tank 16 is located below the accumulation tank 11, and the recovery port 111 is connected to the recovery tank 16. A filter bottom 112 is also installed on the surface of the recovery port 111 to filter the tin powder and debris in the accumulation tank 11, so that the cooling lubricant in the recovery tank 16 is purer.

[0041] A fixed groove 18 is also provided in the machine body 1, and a booster pump 34 is installed in the fixed groove 18. One end of the outlet of the booster pump 34 is connected to the circulation main pipe 31, and one end of the inlet of the booster pump 34 is connected to the recovery tank 16. The cooling lubricating liquid is filtered through the filter bottom 112 of the recovery port 111, and flows into the recovery tank 16 after simple sedimentation, and is then transported by the booster pump 34 to the circulation main pipe 31 for recycling. The total amount of lubricating liquid during equipment working hours is reduced, the evaporation loss of the lubricating liquid is reduced, and the actual production cost is reduced.

[0042] As attached Figure 1 and attached Figure 5 As shown, the machine body 1 includes a baffle 12 , a connection block group 17 , a feed conduit 14 and a discharge conduit 15 .

[0043] A limiting groove 13 is also provided on the body 1, and the limiting groove 13 and the baffle 12 can be snapped into place. After the baffle 12 is snapped into the limiting groove 13, the baffle 12 is located on the side of the accumulation tank 11, and the height of the baffle 12 is higher than the height of the spray hole 321. The snap-fitting method facilitates the disassembly and assembly of the baffle 12 in the future, and is also convenient for cleaning the tin powder in the accumulation tank 11 during maintenance.

[0044] The connecting block group 17 is located on the surface of the body 1 on the feed side and the discharge side. The connecting block group 17 includes a first connecting block 171 and a second connecting block 172. The first connecting block 171 and the second connecting block 172 are threadedly connected by bolts. The second connecting block 172 is fixedly connected to the body 1, and the first connecting block 171 and the second connecting block 172 are both provided with semicircular arc holes 173. After the two semicircular arc holes 173 are aligned, the feed conduit 14 and the discharge conduit 15 can fit through. When the feed conduit 14 and the discharge conduit 15 fit through, the bolts on the first connecting block 171 are tightened and fixed to lock the feed conduit 14 and the discharge conduit 15 from the outside to the inside.

[0045] Baffle 12 also has a conduit hole 121, through which both the feed conduit 14 and the discharge conduit 15 pass. These conduits 14, 15, and the center points of the roller assembly 2 are coaxially aligned. These conduits 14, 15 constrain the direction of incoming tin bars and outgoing tin wire, facilitating feeding and discharging and ensuring stable rolling. They also prevent the tensile strength of the tin bars and wire from being thrown out during the rolling process, potentially injuring workers.

[0046] The working principle of this embodiment is as follows:

[0047] After the tin bars continuously enter the previous generation equipment, the feeding conduit 14 constrains the pulling direction of the entering tin bars, which facilitates feeding and prevents the tight tin bars from flying up directly due to breakage during the rolling process and injuring workers. After passing through the direction constraint of the feeding conduit 14, the tin bars are pulled and squeezed forward by different groups of pressure roller groups 2. Under the action of the pulling force caused by the different rotation speeds between different pressure roller groups 2 and the extrusion force caused by the size difference of the pressure grooves 211 between different pressure roller groups 2, the thick tin bars are continuously stretched and pressed until they pass through all the pressure roller groups 2 and are sent to the discharge conduit 15. The discharge conduit 15 constrains the pulling direction of the loose tin wire, which facilitates discharging and prevents the tight tin wire from flying up directly due to breakage during the rolling process and injuring workers.

[0048] When the tin bar is pulled and squeezed between different pressure roller groups 2, the spray pipe 32 on the side of the pressure roller 21 sprays out cooling lubricant. The cooling lubricant can reduce the friction generated by pulling and squeezing, and reduce the risk of the tin bar being broken due to excessive tension. The cooling lubricant flows into the accumulation tank 11 after the injection pressure roller 21 and the tin bar are squeezed. The bottom of the accumulation tank 11 is an inclined surface. The cooling lubricant in the accumulation tank 11 flows into the recovery port 111. The filter bottom 112 on the recovery port 111 filters the cooling lubricant. After filtration and simple sedimentation, the cooling lubricant flows into the recovery tank 16. The booster pump 34 in the fixed tank 18 transports the filtered cooling lubricant to the circulation main pipe 31, thereby recycling the cooling lubricant.

[0049] At the same time, since splashing will occur when the spray hole 321 sprays the cooling lubricant to the pressure roller group 2, a baffle 12 is set on the side of the accumulation tank 11 to prevent the cooling lubricant from splashing when spraying to the pressure roller 21. The baffle 12 can be clamped in the limiting groove 13 on the body 1, which facilitates the disassembly and assembly of the baffle 12, and at the same time facilitates the cleaning of tin powder and debris on the surface of the recovery port 111, thereby improving applicability.

[0050] In summary:

[0051] The present application establishes a cooling lubricating liquid circulation system, in which the cooling lubricating liquid is collected, filtered, and simply settled at the recovery port 111 before flowing into the recovery tank 16, and then transported by the booster pump 34 to the circulation main pipe 31 for recycling. Due to the recycling of the lubricating liquid, the total amount of lubricating liquid during equipment working hours is reduced, the loss of lubricating liquid due to volatilization is reduced, and the actual production cost is reduced.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of protection required by this application, they are protected by patent law.
