Description

Technical Field

[0001] The present invention relates to the technical field of bending machines, and particularly to an industrial machine for automatic extrusion and bending forming of steel plates. Background Technique

[0002] During the working process of a bending machine, the sheet material is extruded and deformed mainly through the extrusion between the extrusion block and the base. During the continuous forming process of the sheet material, due to the intense friction between the extrusion block and the surface of the sheet material and the large pressure generated between the extrusion block and the base, a large amount of heat will be generated at the extrusion block and the base, causing the surface temperature of the extrusion block to rise. When the paint surface on the sheet material comes into contact with the high-temperature extrusion block, it is easy to cause damage, thereby reducing the quality of the finished product. Therefore, a device is needed to slow down the rate of temperature rise during the continuous forming of the sheet material. Summary of the Invention

[0005] The bending mechanism includes a base, the lower surface of the base is fixedly connected with the upper side of the workbench, the upper side of the second hydraulic rod is fixedly connected with the outer wall of the fixed bracket, the lower side of the second hydraulic rod is fixedly connected with the upper side of the extrusion plate, a cavity is opened inside the extrusion plate, both ends of the cavity are communicated with the outside of the extrusion plate, a connecting pipe is communicated with the outside of the extrusion plate at the communicating part of the cavity and the outside of the extrusion plate, one end of the connecting pipe is fixedly connected with the outer wall of the extrusion plate, the other end of the connecting pipe is communicated with a hose, and the other end of the hose penetrates through the fixed bracket and is communicated with a cooling water pump.

[0006] According to the above technical solution, the output end and the input end of the cooling water pump are respectively communicated with two hoses, the lower ends of the two hoses are respectively communicated with one ends of the two connecting pipes, the two ends of the two connecting pipes close to the extrusion plate are respectively communicated with both sides inside the extrusion plate, a mixing mechanism is arranged inside the cavity, and a temperature control switch is fixedly connected to the inner wall of the cavity.

[0007] According to the above technical solution, the mixing mechanism includes a plug rod. The upper end of the plug rod is fixedly connected to the upper side of the inner wall of the cavity. The lower end of the plug rod is sleeved with a sleeve. The inner wall of the sleeve is slidably connected to the outer wall of the plug rod. The upper side of the sleeve is fixedly connected to a spring. The upper end of the spring is fixedly connected to the upper side of the inner wall of the cavity. The lower end of the sleeve is fixedly connected to a collar. The inner wall of the collar is rotatably connected to a rotating rod through a bearing. A plurality of blades are fixedly connected to the inner wall of the rotating rod. The blades are arranged in a ring inside the rotating rod. An impact mechanism is arranged on the outer wall of the rotating rod.

[0008] According to the above technical solution, the impact mechanism includes a hinged ring. The inner wall of the hinged ring is hinged to the outer wall of the rotating rod through a torsion spring. An elastic sheet is fixedly connected to the outer wall of the hinged ring. The other side of the elastic sheet is fixedly connected to an impact rod.

[0009] According to the above technical solution, the middle part of the cavity is narrower. The length of the elastic sheet is greater than the distance between the outer wall of the hinged ring and the middle part of the inner wall of the cavity.

[0010] According to the above technical solution, the inside of the rotating rod is hollow. The two side openings of the rotating rod and the two side openings of the cavity are correspondingly arranged and do not contact each other.

While it is moving up and down, the sleeve, the collar, and the rotating rod will form a relative shaking displacement with the extrusion plate inside the cavity due to their own inertia, so that the rotating rod and the structures on its surface mix the cooling liquid to prevent local high temperature of the cooling liquid;

[0014] During the process of the cooling liquid circulating, the fluid formed by the cooling liquid will drive the blades to rotate the rotating rod, so as to drive the elastic sheet to rotate and mix the hot and cold cooling liquids, so as to achieve the purpose of rapid cooling and prevent uneven mixing;

[0015] During the rotation of the elastic sheet, due to the long length of the elastic sheet, it will be blocked by the middle part of the inner wall of the cavity. Only when the torsion spring inside the hinge ring deforms to the limit will the elastic sheet deform and pass through the middle of the cavity. Due to the elastic force of the torsion spring and the inertia of the elastic sheet, it will drive the impact rod to impact the inner wall of the extrusion plate, causing the tissue on the surface of the extrusion plate to fall off, so as to prevent debris and sundries from adhering to the surface and damaging the surface of the subsequent sheet material.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5, the present invention provides a technical solution: an industrial machine for automatic extrusion and bending of steel plates, including a workbench 1. A first hydraulic rod 2 is fixedly connected to the upper surface of the workbench 1. The upper end of the first hydraulic rod 2 is fixedly connected to a fixed frame 3. The outer wall of the fixed frame 3 is rotatably connected to a transmission roller 4 through a bearing. A motor 5 is fixedly connected to the outer wall of the fixed frame 3. The output end of the motor 5 penetrates the fixed frame 3 and extends to the other side of the fixed frame 3 and is fixedly connected to one end of the transmission roller 4. A fixed bracket 6 is fixedly connected to the outer wall of the workbench 1. A bending mechanism 7 is provided on the fixed bracket 6;

[0025] The bending mechanism 7 includes a base 701. The lower surface of the base 701 is fixedly connected to the upper side of the workbench 1. The upper side of a second hydraulic rod 702 is fixedly connected to the outer wall of the fixed bracket 6. The lower side of the second hydraulic rod 702 is fixedly connected to the upper side of an extrusion plate 703. A cavity 704 is formed inside the extrusion plate 703. Both ends of the cavity 704 are communicated with the outside of the extrusion plate 703. A connecting pipe 705 is communicated with the outside of the extrusion plate 703 at the communicating part. One end of the connecting pipe 705 is fixedly connected to the outer wall of the extrusion plate 703. The other end of the connecting pipe 705 is communicated with a hose 706. The other end of the hose 706 penetrates the fixed bracket 6 and is communicated with a cooling water pump 707.

[0026] The output end and the input end of the cooling water pump 707 are respectively communicated with two hoses 706. The lower ends of the two hoses 706 are respectively communicated with one end of the two connecting pipes 705. The two ends of the two connecting pipes 705 close to the extrusion plate 703 are respectively communicated with both sides inside the extrusion plate 703. A mixing mechanism 708 is arranged inside the cavity 704. A temperature control switch 709 is fixedly connected to the inner wall of the cavity 704.

[0027] The mixing mechanism 708 includes a plug rod 801. The upper end of the plug rod 801 is fixedly connected to the upper side inner wall of the cavity 704. A sleeve 802 is sleeved on the lower end of the plug rod 801. The inner wall of the sleeve 802 is slidably connected to the outer wall of the plug rod 801. A spring 803 is fixedly connected to the upper side of the sleeve 802. The upper end of the spring 803 is fixedly connected to the upper side inner wall of the cavity 704. A collar 804 is fixedly connected to the lower end of the sleeve 802. The inner wall of the collar 804 is rotatably connected to a rotating rod 805 through a bearing. A plurality of blades 807 are fixedly connected to the inner wall of the rotating rod 805. The plurality of blades 807 are arranged in a ring inside the rotating rod 805. The inside of the rotating rod 805 is hollow. The two openings on both sides of the rotating rod 805 are arranged corresponding to the two openings on both sides of the cavity 704, and there is no contact between them. An impact mechanism 806 is arranged on the outer wall of the rotating rod 805.

[0028] The impact mechanism 806 includes a hinged ring 601. The middle of the cavity 704 is narrower. The length of the elastic sheet 602 is greater than the distance between the outer wall of the hinged ring 601 and the middle of the inner wall of the cavity 704. The inner wall of the hinged ring 601 is hinged to the outer wall of the rotating rod 805 through a torsion spring. The outer wall of the hinged ring 601 is fixedly connected with an elastic sheet 602. The other side of the elastic sheet 602 is fixedly connected with an impact rod 603. The elastic sheet 602 is made of an elastic material. The force required for the torsion spring deformation between the outer wall of the hinged ring 601 and the rotating rod 805 is less than the force required for the deformation of the elastic sheet 602.

[0029] During use, connect the input ends of the first hydraulic rod 2 and the second hydraulic rod 702 to the hydraulic pump, connect the motor 5 to the mains power supply, connect the mains power supply to the input end of the temperature control switch 709, and the output end of the temperature control switch 709 is electrically connected to the cooling water pump 707. Start the motor 5 to convey the plate. After the plate moves to the lower side of the pressing plate 703, stop the motor 5. Start the first hydraulic rod 2 to lower the fixed frame 3. After the surface of the plate contacts the base 701, the first hydraulic rod 2 stops working. Then start the second hydraulic rod 702 to press down the pressing plate 703 so that the pressing plate 703 and the base 701 press the plate to make it bend and deform. After forming, start the second hydraulic rod 702 to lift the pressing plate 703, then start the first hydraulic rod 2 to lift the fixed frame 3, and then start the motor 5 to transport the plate away;

[0030] During the process of the pressing plate 703 pressing the plate, it will move up and down. While it is moving up and down, the sleeve 802, the collar 804, and the rotating rod 805 will form a relative shaking displacement with the pressing plate 703 inside the cavity 704 due to their own inertia, causing the insertion rod 801 to slide up and down inside the sleeve 802, causing the spring 803 to elastically contract and stretch, and causing the rotating rod 805 and the structures on its surface to disturb and mix the coolant, so as to prevent local high temperature of the coolant;

[0031] Pre-fill the coolant in the cavity 704 inside the pressing plate 703. After high temperature is generated on the pressing plate 703, its heat will cause the coolant inside the cavity 704. When the temperature control switch 709 receives a higher temperature, it will start the cooling water pump 707. The cooling water pump 707 will pump the coolant inside the pressing plate 703 from one side of the pressing plate 703 through the hose 706 and the connecting pipe 705, cool it, and then input it from the other side of the pressing plate 703. During this process, the effect of cooling the pressing plate 703 is achieved;

[0032] When the coolant passes through the interior of the cavity 704, it drives the blade 807 to rotate, causing the blade 807 to drive the rotating rod 805 to rotate. The elastic sheet 602 on the surface of the rotating rod 805 mixes the coolant. At the same time, since the elastic sheet 602 is relatively long, when it rotates to the middle of the cavity 704, it is blocked by the middle part of the inner wall of the cavity 704. Since the elastic sheet 602 stops rotating and the rotating rod 805 continues to rotate, the torsion spring between the surface of the rotating rod 805 and the hinged ring 601 will contract and deform. Only when the torsion spring inside the hinged ring 601 deforms to the limit will the elastic sheet 602 deform and pass through the middle of the cavity 704. Due to the elastic force of the torsion spring and the inertia of the elastic sheet 602, it drives the impact rod 603 to impact the inner wall of the extrusion plate 703, causing the tissue on the surface of the extrusion plate 703 to fall off, preventing debris and sundries from adhering to its surface and damaging the surface of the subsequent sheet material.
