Description

Technical Field

[0001] This application relates to the field of roll forming equipment technology, and in particular to a roll forming machine with a cooling function. Background Technology

[0002] Currently, roll forming is an energy-saving, material-saving, and efficient metal forming process. Its operation involves using sequentially arranged multi-pass forming rolls to continuously bend metal sheets and strips laterally, thereby producing strip steel with specific end faces.

[0003] Traditional roll forming machines mainly consist of several forming units and a shearing device at the discharge end. Each forming unit includes an upper roll and a lower roll, used to roll the metal sheet. The lower rolls of each pass are connected by a gear set or chain sprocket set located on one side of the frame; while the upper rolls are driven by the gear set of the corresponding lower roll, thus achieving synchronous movement and performing roll forming on the metal sheet.

[0004] Regarding the aforementioned technologies, during the metal rolling process, when pressing thicker sheets, friction generates significant heat, causing the surfaces of the upper and lower rolls to heat up easily. This heat transfer also heats up the formed sheet. After rolling, the sheet naturally cools to room temperature. However, with this temperature change, the originally straight profile can become distorted and deformed, affecting product quality. Therefore, improvements are needed. Utility Model Content

[0005] To facilitate cooling of the rolls and sheet metal during roll forming, this application provides a roll forming machine with a cooling function.

[0006] The roll forming machine with cooling function provided in this application adopts the following technical solution:

[0007] A roll forming machine with cooling function includes a forming machine body, an upper roll, a lower roll, and a cooling assembly. The upper roll and the lower roll are rotatably connected to the forming machine body. The upper roll and the lower roll are arranged opposite each other and are spaced apart along the length of the forming machine body. The cooling assembly is close to the upper roll and is used to cool the upper roll and the lower roll.

[0008] By adopting the above technical solution, during production, the metal sheet passes through the gap between the upper and lower rollers. An external motor drives one of the lower rollers to rotate, and with the cooperation of chains and sprockets, all lower rollers rotate synchronously. The upper roller, on the other hand, relies on the gear set of the corresponding lower roller to achieve synchronous movement, thereby performing roll forming of the metal sheet.

[0009] During the forming process, the cooling components can add coolant to the upper roll. The coolant flows under the action of gravity, which can carry away the heat from the upper roll, the metal sheet and the lower roll, thereby achieving the cooling effect and reducing the possibility of deformation of the metal sheet.

[0010] Preferably, the cooling assembly includes a water tank, water pipes, and universal bamboo-joint pipes. Support rods are provided on the main body of the molding machine, the support rods are located above the upper roller, and the support rods are spaced apart along the length of the main body of the molding machine. The water tank is located on one side of the main body of the molding machine. One end of the water pipe is connected to the water tank and is located on each of the support rods, and the other end of the water pipe is closed.

[0011] The universal bamboo joint tubes are spaced apart along the arrangement direction of each of the support rods and are all connected to the water pipes. Each of the universal bamboo joint tubes is equipped with a valve.

[0012] By adopting the above technical solution, during cooling, the coolant (water) in the storage tank can be pumped into the water pipe. The presence of valves allows operators to easily control the opening and closing of the universal bamboo-joint tube, enabling the cooling water to flow from the universal bamboo-joint tube to the upper roller. The universal bamboo-joint tube is a type of tubing with characteristics such as flexibility and adjustable angle. Operators can adjust the orientation of the universal bamboo-joint tube according to actual needs, changing the relative position of the universal bamboo-joint tube and the upper roller so that the cooling water can flow to the upper roller more effectively.

[0013] Preferably, the forming machine body is provided with a water receiving box, which is located below the lower roller and is used to receive the coolant flowing out of the universal bamboo joint tube; the water receiving box is inclined downward along the direction close to the water storage tank, the water storage tank is open and located below the lower end of the water receiving box.

[0014] By adopting the above technical solution, the cooling water flowing out through the universal bamboo joint tube will flow into the water receiving box under the action of gravity. Since the water receiving box is set at an inclination, the cooling water collected in the water receiving box will flow along the relatively lower end of the water receiving box and then flow back into the water storage tank.

[0015] Preferably, the water storage tank delivers coolant to the water pipe via a water pump.

[0016] By adopting the above technical solution, a water pump is a machine that converts mechanical energy into the pressure energy and kinetic energy of a liquid, thereby realizing the transportation or lifting of the liquid. Under the action of the water pump, the cooling water in the water storage tank can be transported into the water pipe.

[0017] Preferably, the water pipe includes a flexible section and a rigid section, with both ends of the flexible section connected to the water storage tank and the rigid section, respectively, and the rigid section disposed on each of the support rods.

[0018] By adopting the above technical solution, the flexible hose section has good deformation capability, so that the rigid pipe section and the water storage tank can be connected. The rigid pipe section is installed on each support rod to supply water to each universal bamboo joint pipe.

[0019] Preferably, the bottom of the rigid tube is connected to a pin, and the support rod has a through hole through which the pin passes.

[0020] By adopting the above technical solution, the pin can pass through the through hole on the support rod to limit the rigid tube section. Without external force interference, the rigid tube section is not easy to shift its position on the support rod.

[0021] Preferably, a filter screen is provided at the position where the hose connects to the water storage tank.

[0022] By adopting the above technical solution, the filter screen can intercept and filter some particulate impurities in the cooling water, making the cooling water flowing out of the universal bamboo joint pipe relatively clean and reducing the pollution of the cooling water to the metal plate.

[0023] Preferably, a diversion column is provided at one end of the water receiving box near the water storage tank. The diversion column is conical and used for diverting water.

[0024] By adopting the above technical solution, the presence of the diversion column can divert the cooling water at the end of the water box, making it easier for the cooling water to flow back into the water storage tank.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] (1) By setting up a cooling component, during cooling, the coolant (water) in the water tank can be pumped to the water pipe through the action of the water pump. The water in the water pipe flows to the upper roller through the universal bamboo joint tube. The coolant flows downward under the action of gravity, which can carry away the heat of the upper roller, metal plate and lower roller, thereby achieving the cooling effect, reducing the possibility of deformation of the metal plate and improving product quality.

[0027] (2) By setting up a water collection box, the water collection box can collect the cooling water flowing out of the universal bamboo joint pipe and then return it to the water storage tank to achieve recycling.

[0028] (3) By setting up a filter screen, the filter screen can intercept and filter some particulate impurities in the cooling water, preventing these impurities from entering the water pipe, so that the cooling water flowing out of the universal bamboo joint pipe is relatively clean.

For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0037] This application discloses a roll forming machine with a cooling function. (Refer to...) Figure 1 and Figure 2The roll forming machine includes a forming machine body 1, an upper roll 2, a lower roll 3, and a cooling assembly 4. Both the upper roll 2 and the lower roll 3 are rotatably connected to the forming machine body 1, and their rotation axes are parallel to each other. The upper roll 2 and the lower roll 3 are arranged vertically opposite each other, with the upper roll 2 located above the lower roll 3, and both are spaced apart along the length of the forming machine body 1. The cooling assembly 4 is located near the upper roll 2 and is used to cool both the upper roll 2 and the lower roll 3.

[0038] Specifically, the cooling assembly 4 includes a water storage tank 41, water pipes 42, and universal bamboo-joint pipes 43. The water storage tank 41 is installed at one end of the molding machine body 1 and is open, used to store cooling water. Support rods 7 are fixedly connected to the molding machine body 1, located above the upper roller 2, and several support rods 7 are arranged parallel to each other, spaced apart along the length of the molding machine body 1. One end of the water pipe 42 is connected to the water storage tank 41, and the other end is closed. Cooling water in the water storage tank 41 is pumped into the water pipe 42. The water pipe 42 is installed on each support rod 7. The water pipe 42 can be fixedly connected to the support rod 7, for example, by welding; the water pipe 42 and the support rod 7 can also be detached and connected, for example, by insertion or snap-fit. The universal bamboo-joint pipes 43 are arranged along the direction of the support rods 7 and are all connected to the water pipes 42. The end of the universal bamboo-joint pipe 43 away from the water pipe 42 faces the upper roller 2. Each universal bamboo joint tube 43 is equipped with a valve, which is used to control the opening and closing of the universal bamboo joint tube 43.

[0039] During production, the metal sheet passes through the gap between the upper roll 2 and the lower roll 3. An external motor drives one of the lower rolls 3 to rotate, and with the help of chains and sprockets, all the lower rolls 3 rotate synchronously. The upper roll 2, on the other hand, relies on the gear set of the corresponding lower roll 3 to achieve synchronous movement, thus performing roll forming of the metal sheet.

[0040] During the workpiece forming process, the coolant (water) in the water tank 41 can be pumped to the water pipe 42. The valve allows the operator to control the opening and closing of the universal joint pipe 43, allowing the cooling water to flow from the universal joint pipe 43 to the upper roll 2. The coolant flows under gravity, carrying away heat from the upper roll 2, the metal plate, and the lower roll 3, thus achieving a cooling effect, reducing the possibility of deformation of the metal plate, and ensuring product quality.

[0041] In this embodiment, the water pipe 42 includes a flexible hose 421 and a rigid hose 422. The flexible hose 421 is flexible and can be made of materials such as polyvinyl chloride or polyethylene. The rigid hose 422 is more rigid and can be made of metal. Both ends of the flexible hose 421 are connected to the water storage tank 41 and the rigid hose 422, respectively. A filter screen (not shown in the figure) is also installed at the end of the flexible hose 421 that connects to the water storage tank 41. The filter screen is used to filter impurities in the cooling water. The rigid hose 422 is arranged in a straight line and is installed on each support rod 7. In some embodiments, a pin (not shown in the figure) is fixedly connected to the side of the rigid hose 422 facing the support rod 7. A through hole is provided on the support rod 7 for the pin to pass through. The rigid hose 422 and the support rod 7 are detachably connected by the cooperation of the pin and the through hole. Without external interference, the rigid hose 422 is not prone to displacement on the support rod 7.

[0042] In addition, a water receiving box 5 is installed on the main body 1 of the molding machine. The water receiving box 5 has an opening and is located below each lower roller 3. The water receiving box 5 is used to collect the coolant flowing out of each universal bamboo joint tube 43. The water receiving box 5 is inclined downward along the direction close to the water storage tank 41, that is, one end of the water receiving box 5 is higher and the other end is lower. In this embodiment, the end of the water receiving box 5 close to the water storage tank 41 is lower. The water storage tank 41 is a lidless cuboid shape, and the lower end of the water receiving box 5 is above the opening of the water storage tank 41.

[0043] Cooling water flowing out through the universal bamboo joint pipe 43 will flow into the water collection box 5 under the action of gravity. Since the water collection box 5 is set at an inclination, the cooling water collected in the water collection box 5 will flow along the relatively lower end of the water collection box 5 and then flow back into the water storage tank 41, realizing the recycling of cooling water.

[0044] The water receiving box 5 is fixedly connected to a diversion column 6 near the water storage tank 41. The diversion column 6 is tapered and used for diverting water flow. The cross-section of the diversion column 6 gradually decreases along the direction near the water storage tank 41. The presence of the diversion column 6 allows the cooling water at the end of the water receiving box 5 to flow back into the water storage tank 41 more easily.

[0045] The implementation principle of a roll forming machine with cooling function according to an embodiment of this application is as follows: When the workpiece is being roll formed, the cooling water in the water tank 41 is transported to the water pipe 42 under the drive of the water pump. The water in the water pipe 42 flows through the universal bamboo joint pipe 43 and flows precisely to the upper roll 2. The coolant flows downward naturally under the action of gravity. In this process, it effectively removes the heat generated by the upper roll 2, the metal plate, and the lower roll 3, thereby achieving the cooling purpose. This cooling mechanism can effectively reduce the probability of deformation of the metal plate and ensure product quality.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
