Description

Technical Field

[0001] This utility model relates to the field of automotive hot rolling processing technology, and in particular to a rolling forming device for hot-rolled pickled structural parts for automobiles. Background Technology

[0002] Hot rolling is the opposite of cold rolling. Cold rolling is rolling performed below the recrystallization temperature, while hot rolling is rolling performed above the recrystallization temperature. Simply put, a steel billet is heated, rolled several times, trimmed, and straightened to become a steel plate. This is called hot rolling, which can significantly reduce energy consumption and costs. During hot rolling, the metal has high plasticity and low deformation resistance, greatly reducing the energy consumption of metal deformation. For hot rolling in automotive processing, a calendering and forming device for hot-rolled pickled structural parts is required. Calendering involves passing plasticized thermoplastic material close to its viscous flow temperature through a series of horizontally rotating rollers, subjecting the material to extrusion and stretching to form a thin sheet product with a certain thickness, width, and smooth surface.

[0003] To this end, the specification of patent CN113145641B discloses a stainless steel hot rolling forming device. By setting a pressure module, the steel billet can be repeatedly rolled. In conjunction with a moving module, the steel billet can be rolled while moving horizontally, thereby processing the steel billet to the required thickness. By setting a cooling module, the processed stainless steel plate can be cooled, thereby improving the surface hardness of the stainless steel plate. Furthermore, by setting a cooling module, the steel plate can also be turned into a steel coil, thereby facilitating the user to transport the steel coil.

[0004] The aforementioned stainless steel hot rolling forming device proposes that by setting a cooling module, steel plates can also be turned into steel coils, which facilitates the transportation of steel coils by users. However, during use, the plates may shift during processing, and dust may accumulate on the plates, affecting the quality of plate processing. Utility Model Content

[0005] The purpose of this invention is to provide a rolling forming device for hot-rolled pickled structural parts for automobiles, in order to solve the defect of existing rolling forming devices for hot-rolled pickled structural parts for automobiles that are difficult to limit the position of the sheet metal.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rolling and forming device for hot-rolled pickled structural parts for automobiles, including support legs;

[0007] A water tank is installed at the top of the support leg, a workbench is installed at the top of the water tank, and a bracket is installed at the top of the workbench.

[0008] A lower calendering roller is installed at the bottom of the inner side of the bracket, and an upper calendering roller is installed at the top of the inner side of the bracket. A servo motor is installed at one end of the lower calendering roller and the upper calendering roller, and a limit structure is installed on both sides of the top of the worktable.

[0009] The limiting structure includes a first telescopic rod installed on both sides of the top of the workbench, a second telescopic rod installed at the top of the first telescopic rod, and an installation block installed at the top of the second telescopic rod.

[0010] In use, the screw and the bracket form a threaded connection. Tightening the screw block can drive the screw to rotate. The rotation of the screw will drive the moving block, which forms a threaded connection with it, to rise and fall. The moving block and the moving groove form a sliding structure. The moving block can slide along the moving groove. The sliding of the moving block can adjust the height of the upper calendering roller, so that the gap between the upper calendering roller and the lower calendering roller can be adjusted. The servo motor can drive the upper calendering roller and the lower calendering roller to rotate, and drive the plate passing through to perform calendering processing.

[0011] Furthermore, a spraying mechanism is installed on both sides of the water tank, and the spraying mechanism includes a water pump installed at both ends of the water tank. A conduit is installed at the top of the water pump, and the water pump can draw water out from the conduit.

[0012] Furthermore, a nozzle is installed at the top of the conduit, and the nozzles are arranged at equal intervals at the top of the conduit, and the nozzles can spray water.

[0013] Furthermore, guide rods are inserted through both ends of the mounting block, a fixing screw is installed at one end of the first telescopic rod, a threaded rod is inserted through the middle position inside the mounting block, a pressure plate is installed at the bottom end of the threaded rod, a base plate is installed at the bottom end of the mounting block, and brushes are installed at the top end of the base plate and the bottom end of the pressure plate. The pressure plate and the base plate can limit the position of the plate.

[0014] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the mounting block is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the mounting block are threadedly connected, and the rotation of the threaded rod can drive the pressure plate to rise and fall.

[0015] Furthermore, both ends of the upper calender roll are equipped with adjustment structures. The adjustment structure includes a movable groove disposed at the top of the support, a movable block installed inside the movable groove, a screw passing through the middle of the movable block, and a screwing block installed at the top of the screw. The gap between the calender rolls can be adjusted by adjusting the height of the upper calender roll.

[0016] Furthermore, the moving groove is provided with a sliding groove inside, and the moving block is provided with sliders on both sides. The moving groove and the moving block form a sliding structure, and the moving block can slide inside the moving groove.

[0017] The advantages of the calendering and forming device for hot-rolled pickled structural parts for automobiles provided by this utility model are as follows: during use, the sheet metal can be clamped by the pressure plate and the base plate to prevent the sheet metal from shifting during processing. At the same time, the sheet metal can be cleaned by the brush, and water can be sprayed out by the nozzle to cool the calendered sheet metal.

[0018] A second telescopic rod is installed at the top of the first telescopic rod. The second telescopic rod can slide inside the first telescopic rod. The sliding of the second telescopic rod can adjust the height of the mounting block. Tightening the fixing screw can fix the second telescopic rod. At the same time, the sheet metal to be processed can pass between the pressure plate and the base plate. The threaded rod and the mounting block form a threaded connection. The rotation of the threaded rod can adjust the lifting and lowering of the pressure plate. The lifting and lowering of the pressure plate can adjust the height of the pressure plate, allowing the pressure plate to adapt to different situations. The pressure plate and the base plate can clamp the sheet metal in the middle and limit the sheet metal. At the same time, when the sheet metal passes through the mounting block, the brush can clean the surface of the pressure plate and reduce the dust on the pressure plate. This achieves the purpose of facilitating the limiting of sheet metal in the calendering and forming device for hot-rolled pickled structural parts of automobiles.

[0019] By installing water pumps at both ends of the water tank, the water pumps can draw water through pipes and then deliver the water to the nozzles. The nozzles can spray water onto the calendered sheet to cool it and prevent the temperature from getting too high during calendering, which could lead to dangerous situations. At the same time, the water can also clean the sheet. This achieves the purpose of facilitating the cooling of the sheet in the calendering and forming device for hot-rolled pickled structural parts for automobiles. Attached Figure Description
