Technical Field

[0001] The present invention relates to the field of stamping technology, and specifically to a pressing plate device for the manufacture of prefabricated color steel structures. Background Art

[0002] Color steel tiles, also known as: colored profiled tiles, are profiled plates made of colored coated steel sheets and roll-pressed and cold-bent into various corrugations. It is applicable to the roofs, walls, and interior and exterior wall decorations of industrial and civil buildings, warehouses, special buildings, and large-span steel structure houses. It has the characteristics of light weight, high strength, rich colors, convenient and fast construction, earthquake resistance, fire prevention, rain prevention, long service life, and maintenance-free, and has now been widely promoted and applied. When traditional color steel tiles are manufactured, they are mostly roll-pressed and formed by rollers. Since the rollers need to apply a large pressure and the structure of the rollers is fixed, the equipment can only perform roll-pressing operations on plates with a fixed thickness at a fixed angle, and the flexibility of the equipment is poor. Moreover, as the roll-pressing continues, the rollers are continuously worn, and manual monitoring and replacement of consumables are required, which affects production efficiency. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a pressing plate device for the manufacture of prefabricated color steel structures, which solves the problems of fixed structure and low efficiency of traditional color steel manufacturing equipment.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A pressing plate device for the manufacture of prefabricated color steel structures, including a bottom plate, on the upper surface of which a hydraulic device is fixedly connected. A rolling device is arranged on the right side of the hydraulic device. The coil is curled inside the hydraulic device. When the equipment starts pressing plate manufacturing, the coil is continuously drawn out, and the self-weight of the coil decreases. The rolling device is responsible for rolling the drawn-out coil flat to avoid large stamping wrinkles and stamping errors caused by excessive curling of the coil. A stamping device is arranged on the right side of the rolling device. The hydraulic device includes a sealing plate, on the inner surface of which a vertical rod is slidably connected. A piston is fixedly connected to the outer surface of the vertical rod. A connecting pipe is arranged at the bottom of the piston. The sealing plate is fixed on the top of the bottom plate. The thin steel coil is installed inside the sealing plate. Under the pressure of the steel coil, the vertical rod drives the piston to move downward. The hydraulic oil inside the sealing plate is squeezed upward from the bottom end of the connecting pipe into the inside of the opening and closing device, and the opening and closing device clamps the top of the steel coil. The top end of the connecting pipe is provided with an opening and closing device.

[0005] Preferably, the opening and closing device includes a push rod, the top end of the push rod is fixedly connected with a slider, the upper surface of the slider is fixedly connected with a fixed plate, the push rod jacks up the slider, the slider drives the fixed plate and the movable plate to slide upward along the outer surface of the sealing plate. When the top of the movable plate crosses the top of the sealing plate, the compression spring pushes the movable plate to rotate, and the movable plate catches the rotating shaft of the coil to prevent the rotating shaft from driving the coil to jump up and down when the coil is pulled.

[0006] Preferably, the lower surface of the sealing plate is fixedly connected with the upper surface of the bottom plate, and the outer surface of the piston slides with the inner surface of the sealing plate. As the steel coil is pulled, the mass of the coil decreases, the hanging rod resets upward, and the opening and closing device opens. On the contrary, when the movable plate moves downward, the outer surface of the movable plate slides and presses against the outer surface of the sealing plate, the movable plate rotates, and the compression spring is compressed. The top of the coil is vacated, and the coil can be replaced. Until the coil is completely pulled out, the core is taken out, and a new steel coil is replaced.

[0013] The present invention provides a pressing plate device for the manufacture of prefabricated color steel structures. It has the following beneficial effects: (1). In the pressing plate device for the manufacture of prefabricated color steel structures, by setting a hydraulic device, when the equipment is in use, the sealing plate is fixed on the top of the bottom plate, and the thin steel coil is installed inside the sealing plate. Under the pressure of the steel coil, the vertical rod drives the piston to move downward, and the hydraulic oil inside the sealing plate is squeezed upward from the bottom end of the connecting pipe into the inside of the opening and closing device. The opening and closing device clamps the top of the steel coil. As the steel coil is pulled out, the quality of the coil decreases, the vertical rod resets upward, and the opening and closing device opens until the coil is completely pulled out, the core is taken out, and a new steel coil is replaced. By repeating the above steps, the equipment realizes the automatic monitoring of materials, solving the problem that traditional color steel coils require manual monitoring and replacement.

[0014] (2). In the pressing plate device for the manufacture of prefabricated color steel structures, by setting an opening and closing device, when the equipment is in use, the ejector rod jacks up the slider, and the slider drives the fixed plate and the movable plate to slide upward along the outer surface of the sealing plate. When the top of the movable plate crosses the top of the sealing plate, the compression spring pushes the movable plate to rotate, and the movable plate clamps the rotating shaft of the coil, preventing the rotating shaft from driving the coil to jump up and down when the coil is pulled out. On the contrary, when the movable plate moves downward, the outer surface of the movable plate slides and squeezes against the outer surface of the sealing plate, the movable plate rotates, and the compression spring is compressed, leaving the top of the coil empty, and the coil can be replaced, solving the problem that traditional color steel coils are prone to shaking when being pulled out.

[0015] (3). In the pressing plate device for the manufacture of prefabricated color steel structures, by setting a rolling device, when the equipment is in use, the bracket is fixed on the upper surface of the bottom plate. After the coil is pulled out from the inside of the hydraulic device, it alternately passes through the outer surfaces of the rollers up and down in sequence. Under the action of the two rollers, the coil covers the outer surface of the rollers in an S shape, and the coil is stretched and straightened. By rotating the screw rod, the left roller slides left and right along the inner surface of the bracket, and the straightening degree of the coil is controlled by adjusting the distance between the two rollers, so as to meet the stretching of coils of different materials. During the process of rotation and stretching of the rollers, the curling stress of the coil is eliminated, making the coil flatter before stamping and reducing the wrinkles and errors during stamping, solving the problem that traditional color steel structure coils have a large curling degree.

[0016] (4). In the pressing plate device for the manufacture of prefabricated color steel structures, by setting an adjusting device, when the equipment is in use, the locking nut controls the inclination angle of the triangular frame by tightening and loosening. Under the control of the electronic control unit inside the equipment, the telescopic rod extends and contracts, and the telescopic rod jacks up the driving wheel. By changing the distance between the two driving wheels, the friction force of the driving wheel on the plate is controlled, so as to meet the pulling of plates of different thicknesses. The driving wheel and the roller cooperate with each other, enabling the coil to be flatter, solving the problem that traditional color steel plates pulled out of the equipment can only pull plates of a fixed thickness.

[0017] (V). The pressing plate device for the manufacture of prefabricated color steel structures is provided with a stamping device. When the equipment is in use, the bearing plate is fixed on the upper surface of the bottom plate. After the coil material is extruded, it is inserted from the left side of the pressure wheel. Under the action of the inclined rod, the pressure wheel and the auxiliary wheel jointly extrude the plate material. The plate material is roll-pressed on the upper surface of the bearing plate, reducing the edge warping of the plate material. A female die is installed in the groove at the bottom of the gantry. The limit pin catches the male die, and the male die is fixed at the bottom of the stamping plate. The cam drives the connecting rod to move, and the pressing rod pushes the stamping plate to slide up and down along the outer surface of the gantry. The plate material is placed on the upper surface of the female die, and the female die and the male die come into contact and extrude each other, and the plate material is stamped into shape. Color steel structures with different folding angles can be stamped according to molds of different shapes. A section of colored steel plate after stamping is drawn out from the right side of the bearing plate, and so on until all the coil materials are stamped, solving the problem that traditional color steel manufacturing equipment can only manufacture plates with fixed sizes and shapes.

[0018] (VI). The pressing plate device for the manufacture of prefabricated color steel structures is provided with a hydraulic device, a roll-pressing device and a stamping device. When the equipment is in use, the coil material is coiled inside the hydraulic device. When the equipment starts to press the plate for manufacturing, the coil material is continuously drawn out, and the self-weight of the coil material decreases. The roll-pressing device is responsible for roll-pressing the drawn-out coil material flat, avoiding large stamping wrinkles and stamping errors caused by excessive coiling of the coil material. The coil material is roll-pressed into a plate material, and the plate material enters the inside of the stamping device. Under the extrusion of the stamping die, the plate material is bent into color steel structures with different angles. The whole equipment is connected modularly, and each mechanism cooperates with each other, capable of completing the integrated operation of pulling out, roll-pressing and stamping of the coil material. The flexibility of the equipment in use is relatively large, solving the problem that traditional color steel manufacturing equipment has a fixed structure and poor flexibility.
