Description

Technical Field

[0001] This utility model relates to the field of calendering technology, and in particular to a straightening calendering machine with a cooling system. Background Technology

[0002] In the field of metal processing, metal bars are the basic raw materials, and their quality directly affects the performance and quality of downstream products. During the production and subsequent processing of metal bars, many factors, such as slight deviations in the rolling process and bumps and collisions during transportation, can easily cause the metal bars to bend and deform, and the surface roughness is difficult to achieve an ideal state. In order to make the metal bars meet the high-precision processing standards, straightening and burnishing have become indispensable key processes.

[0003] Most straightening machines can only operate on metal bars of specific specifications. When processing bars of different diameters or materials, it is often necessary to replace a large number of parts or even the entire machine. This is cumbersome and costly, which greatly limits the flexibility and efficiency of production. Furthermore, the drawbacks of traditional straightening and calendering equipment in terms of coolant use and disposal are becoming increasingly apparent. The use of large amounts of coolant not only wastes resources, but coolant leaks may also pollute the surrounding environment. Therefore, we propose a straightening and calendering machine with a cooling system to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a straightening and calendering machine with a cooling system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A straightening and calendering machine with a cooling system includes: a metal rod and a worktable. Two sets of side plates and a machine housing are fixedly mounted on the top of the worktable. Four sets of guide rods are fixedly mounted inside the machine housing. Two sets of movable plates are slidably mounted on the outer sides of the four sets of guide rods. Two sets of wheel seats and support plates are fixedly mounted on one side of each of the two sets of movable plates. Straightening wheels are rotatably mounted inside the two sets of wheel seats on the left side, and calendering wheels are rotatably mounted inside the two sets of wheel seats on the right side. Synchronizing pulleys are fixedly mounted on one side of both the straightening and calendering wheels. The synchronous pulleys of adjacent sets of synchronized pulleys... A synchronous belt is installed on the outer drive, and a drive motor is fixedly installed on one side of each of the two sets of support plates. A linkage plate is rotatably installed on the inner walls of both sides of the machine box. A transmission rod is hinged to both sides of the two sets of linkage plates and the two sets of moving plates. A cooling oil tank is installed inside the worktable. A filter plate is installed on the top of the cooling oil tank. A circulation pump is fixedly installed on one side of the cooling oil tank. An oil outlet pipe is connected to the oil outlet end of the circulation pump. Multiple atomizing nozzles are connected to the outside of the oil outlet pipe. The metal rod is set inside the two sets of side plates and abuts against the adjacent straightening roller and the adjacent pressing roller.

[0006] Preferably, a filler port is provided on one side of the cooling oil tank, and a sealing cap is fitted on the outside of the filler port. A liquid level window is provided on one side of the cooling oil tank. An adjusting motor is fixedly installed on the top of the chassis, and a screw is fixedly installed on the output end of the adjusting motor. A threaded sleeve is fixedly installed on the top of the movable plate located at the top.

[0007] Preferably, the bottom of the workbench is fixedly equipped with multiple sets of support legs, and the bottom of each set of support legs is provided with an anti-slip pad.

[0008] Preferably, one side of each of the two sets of synchronous pulleys is fixedly mounted on the output end of the corresponding drive motor.

[0009] Preferably, the screw is threaded onto the inner wall of the threaded sleeve, and the screw is rotatably mounted on the top of the housing.

[0010] Preferably, the multiple sets of atomizing nozzles are located on top of the metal rod and the filter plate.

[0011] In this utility model, a straightening and calendering machine with a cooling system is provided. By setting a liquid level window, the liquid level of the coolant inside the cooling oil tank can be visually checked. If the liquid level is lower than the standard value, the sealing cap on the outside of the filling port can be opened to add sufficient coolant to the cooling oil tank through the filling port. After adding, the sealing cap is tightened to prevent coolant contamination or leakage. By setting support legs and anti-slip pads, the stability and safety of the equipment operation are further improved, avoiding safety accidents or affecting the processing quality caused by equipment sliding. In this utility model, a straightening and calendering machine with a cooling system is described. The sprayed coolant carries metal scraps and impurities generated during the processing and falls onto a filter plate below. The filter plate filters the coolant, trapping the scraps and impurities to prevent them from entering the cooling oil tank and contaminating the coolant. The filtered coolant flows back into the cooling oil tank through the filter plate, realizing the recycling of the coolant and reducing the cost of coolant consumption. At the same time, the design of the atomizing nozzle not only improves the cooling efficiency but also reduces the amount of coolant used, avoiding waste and environmental pollution. This utility model features a reasonable structural design. An adjusting motor drives a screw to rotate. Since the screw is threadedly connected to a threaded sleeve on the top moving plate, the screw's rotation is converted into linear motion of the threaded sleeve. This, in turn, causes the top moving plate to slide up and down along four sets of guide rods inside the machine housing. As the top moving plate moves, transmission rods hinged on both sides push a linkage plate to rotate on the inner wall of the machine housing. The linkage plate then drives the bottom moving plate to slide synchronously along the guide rods via another transmission rod, ultimately adjusting the distance between the two sets of moving plates. This ensures that the distance between the straightening roller and the calendering roller mounted on the wheel seat matches the specifications of the metal rod, preventing the metal rod from shifting during feeding and ensuring that the metal rod accurately enters the processing area of ​​the straightening roller and the calendering roller. Two drive motors are activated, driving the connected synchronous rollers to rotate. Under the transmission of the synchronous belt, adjacent synchronous rollers rotate synchronously, causing the straightening roller and the calendering roller to rotate inside the wheel seat. The rotating straightening roller applies lateral pressure to the metal rod it contacts. The process straightens the metal rods, which are then fed forward. During rotation, the calendering rollers apply pressure to the surface of the metal rods, utilizing the plastic deformation properties of metal to improve surface roughness and achieve surface calendering, thus enhancing the appearance quality and surface precision of the metal rods. A circulating pump draws coolant from the cooling oil tank into the outlet pipe, which then delivers it to various atomizing nozzles. These nozzles atomize the coolant and spray it evenly onto the surface of the metal rods. The atomized coolant has a large contact area with the high-temperature components, allowing for rapid heat absorption and effectively reducing the temperature of the metal rods and rollers. This prevents oxidation and deformation of the metal rod surface due to high temperatures, making the equipment more versatile and meeting the needs of small-batch, multi-specification production. It also reduces equipment procurement costs, increases equipment utilization, significantly improves the appearance quality and surface precision of the metal rods, and reduces coolant consumption, further lowering coolant costs.

[0015] Reference Figure 1-4 A straightening and calendering machine with a cooling system includes: a metal rod 1 and a worktable 2. Two sets of side plates 3 and a machine housing 4 are fixedly installed on the top of the worktable 2. Four sets of guide rods 17 are fixedly installed inside the machine housing 4. Two sets of movable plates 14 are slidably installed on the outer sides of the four sets of guide rods 17.

Synchronizing wheels 23 are fixedly installed on one side of each of the two sets of straightening wheels 19 and calendering wheels 20. Adjacent sets of synchronous wheels 23... A synchronous belt 24 is installed on the outer side of the 3. A drive motor 22 is fixedly installed on one side of each of the two sets of support plates 21. A linkage plate 15 is rotatably installed on the inner walls of both sides of the machine box 4. A transmission rod 16 is hinged to both sides of the two sets of linkage plates 15 and the two sets of moving plates 14. A cooling oil tank 6 is installed inside the workbench 2. A filter plate 9 is installed on the top of the cooling oil tank 6. A circulation pump 7 is fixedly installed on one side of the cooling oil tank 6. An oil outlet pipe 8 is connected to the oil outlet end of the circulation pump 7. Multiple atomizing nozzles 10 are connected to the outside of the oil outlet pipe 8. A metal rod 1 is set inside the two sets of side plates 3 and abuts against the adjacent straightening roller 19 and the adjacent pressing roller 20.

[0016] In this embodiment, a filler port 602 is provided on one side of the cooling oil tank 6, and a sealing cap is fitted on the outside of the filler port 602. A liquid level window 601 is provided on one side of the cooling oil tank 6. An adjusting motor 5 is fixedly installed on the top of the casing 4. A screw 12 is fixedly installed on the output end of the adjusting motor 5. A threaded sleeve 13 is fixedly installed on the top of the movable plate 14 located at the top, to ensure the cleanliness and cooling effect of the coolant, thereby ensuring that the cooling system can stably perform its cooling function on the calendering wheel 20 and the metal rod 1.

[0017] In this embodiment, multiple sets of support legs 11 are fixedly installed on the bottom of the workbench 2. The bottom of each set of support legs 11 is provided with anti-slip pads to further improve the stability and safety of the equipment operation and avoid safety accidents or affecting the processing quality caused by the equipment sliding.

[0018] In this embodiment, one side of each of the two sets of synchronous pulleys 23 is fixedly installed on the output end of the corresponding drive motor 22 to ensure that the equipment can continuously and stably perform straightening and calendering of the metal rod 1, thereby improving production efficiency and product quality stability.

[0019] In this embodiment, the screw 12 is threaded onto the inner wall of the threaded sleeve 13. The screw 12 is rotatably mounted on the top of the machine housing 4 to ensure that the pressure between the pressing wheel 20 and the metal rod 1 is appropriate and that the cooling nozzle is aligned with the cooling part, thus ensuring the processing quality.

[0020] In this embodiment, multiple sets of atomizing nozzles 10 are located on top of the metal rod 1 and the filter plate 9, which results in faster heat dissipation and a more significant cooling effect. This effectively reduces the heat generated during the calendering process and prevents problems such as oxidation and deformation on the surface of the metal rod 1 due to high temperatures.

[0021] In this embodiment, during use, the liquid level window 601 is set to visually check the liquid level of the coolant inside the cooling oil tank 6. If the liquid level is lower than the standard value, the sealing cover on the outside of the filling port 602 can be opened to add sufficient coolant to the cooling oil tank 6 through the filling port 602. After adding, the sealing cover is tightened to prevent coolant contamination or leakage. By setting the support legs 11 and anti-slip pads, the stability and safety of the equipment operation are further improved, avoiding safety accidents caused by equipment sliding or affecting the processing quality. One end of the metal rod 1 to be processed is placed into the channel between the two sets of side plates 3, allowing the metal rod 1 to gradually enter the machine housing 4 and abut against the adjacent straightening roller 19 and pressing roller 20. The adjusting motor 5 is started to drive the screw 12 to rotate. Since the screw 12 is threadedly connected to the threaded sleeve 13 located on the top moving plate 14, the rotation of the screw 12 is converted into the linear motion of the threaded sleeve 13, which in turn drives the top moving plate 14 to slide up and down along the four sets of guide rods 17 inside the machine housing 4. When the top moving plate 14 moves, the transmission rods 16 hinged on both sides push the linkage plate 15 to rotate on the inner wall of the machine housing 4. The linkage plate 15 then drives the bottom moving plate 14 to slide synchronously along the guide rods 17 through the transmission rod 16 on the other side, finally realizing the adjustment of the distance between the two sets of moving plates 14, so that the straightening roller 19 and the pressing roller mounted on the wheel seat 18 can move together. The 20mm spacing is adapted to the specifications of the metal rod 1 to prevent the metal rod 1 from deviating during the feeding process and to ensure that the metal rod 1 can accurately enter the processing area of ​​the straightening wheel 19 and the calendering wheel 20. The two sets of drive motors 22 are started to drive the synchronous wheel 23 connected to them to rotate. Under the transmission action of the synchronous belt 24, the adjacent synchronous wheel 23 rotates synchronously, so that the straightening wheel 19 and the calendering wheel 20 rotate inside the wheel seat 18. The rotating straightening wheel 19 applies lateral pressure to the metal rod 1, so that the metal rod 1 reaches a straight state. After straightening, the metal rod 1 continues to be conveyed forward. During the rotation of the calendering wheel 20, a certain pressure is applied to the surface of the metal rod 1. By utilizing the plastic deformation characteristics of metal, the surface roughness of the metal rod 1 is improved, the surface calendering treatment is achieved, and the appearance quality and surface precision of the metal rod 1 are improved. The activated circulation pump 7 draws coolant from the cooling oil tank 6 into the oil outlet pipe 8, and then delivers it to each set of atomizing nozzles 10. The atomizing nozzles 10 atomize the coolant and spray it evenly onto the surface of the metal rod 1. The atomized coolant has a large contact area with the high-temperature components, which can quickly absorb heat and effectively reduce the temperature of the metal rod 1 and the wheel body, preventing oxidation and deformation of the surface of the metal rod 1 due to high temperature. The sprayed coolant carries metal debris and impurities generated during the processing and falls onto the filter plate 9 below. The filter plate 9 filters the coolant, trapping debris and impurities to prevent them from entering the cooling oil tank 6 and contaminating the coolant. The filtered coolant flows back into the cooling oil tank 6 through the filter plate 9, realizing the recycling of coolant and reducing coolant consumption costs. At the same time, the design of the atomizing nozzles 10 not only improves cooling efficiency but also reduces the amount of coolant used, avoiding waste and environmental pollution.
