Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessels, and in particular relates to a plate rolling device for pressure vessel production. Background Art

[0002] Pressure vessels are specially designed and manufactured closed equipment that can contain and withstand a certain pressure from internal or external gas or liquid. At present, pressure vessels are rolled using plate rolling machines during production.

[0003] The authorization announcement number is CN 219561001 U. A plate rolling device for pressure vessel production includes a plate rolling machine body, a plate transmission mechanism is arranged at the left front end of the plate rolling machine, a plate adjustment mechanism is arranged on the plate transmission mechanism, and the plate adjustment mechanism includes two plate adjustment feed seats, the two plate adjustment feed seats are symmetrically arranged at the top of the two transmission seats, and the two plate adjustment feed seats are evenly distributed on the sides close to each other with corresponding plate adjustment push rods, and the ends of each two corresponding plate adjustment push rods close to each other are connected to plate adjustment push wheels through a rotating shaft. The utility model adjusts the plate to be rolled by the cooperation of the plate transmission mechanism and the plate adjustment mechanism, and the adjustment accuracy is high, which effectively improves the bending and rolling processing quality of the plate to be rolled;

[0004] Although the processing of pressure vessel raw materials can be achieved, there are still some problems in daily use. First of all, the method of solely relying on the plate correction top wheel to correct the plate can only guide and prevent the pressure vessel raw materials entering the rolling equipment from deflecting. After the pressure vessel raw materials are rolled to a certain extent, the ends of the pressure vessel raw materials that have not entered the rolling area will be stressed and warp up. At the same time, it is also impossible to guide the arc-shaped pressure vessel raw materials in the rolling process, which makes the pressure vessel raw materials still deflect and tilt during rolling. This will cause the pressure vessel to present an elliptical or other non-circular shape, which will reduce the quality of pressure vessel production and the accuracy of subsequent assembly and use, and cannot ensure the smoothness and precision of the pressure vessel rolling process. Secondly, the pressure vessel raw materials rolled into a circle will rebound due to the rigidity of the material, resulting in the problem of too far offset at the interface, making it inconvenient to weld.

[0010] The anti-rebound mechanism also includes rotating grooves which are respectively arranged on the outer ends of the upper surface of the swing plate, and rotating rollers are rotatably connected in the rotating grooves.

[0011] The plate rolling assembly includes an active roller rotatably connected to the middle of the upper end between the left and right walls of the frame. The left and right walls of the frame are provided with assembly grooves symmetrically distributed in the longitudinal direction. Sliding plates are slidably connected in the assembly grooves. A driven roller is rotatably connected between two laterally adjacent sliding plates. An electric telescopic rod is provided at the lower end of the inner cavity of the assembly groove.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. The relevant staff inserts one end of the pressure vessel raw material between the active roller and the two driven rollers in a group, and then the relevant staff controls the operation of the motor through the external single-chip microcomputer. The rotation of the output shaft of the external single-chip microcomputer drives the corresponding bidirectional screw to rotate synchronously, and the bidirectional screw drives the corresponding sliding block and guide roller to move synchronously along the slide groove during the rotation process, so that the guide roller clamps the left and right ends of the pressure vessel raw material. At the same time, following the actual situation of curling and deformation of the pressure vessel raw material after rolling, the relevant staff first controls the operation of the electric telescopic rod at the discharge end through the external single-chip microcomputer. When the telescopic end of the electric telescopic rod moves, the corresponding swing plate is pushed upward by the fixed plate, so that the pressure vessel raw material in translation, the pressure vessel raw material in an arc state after rolling, and the raised end of the pressure vessel raw material that has not entered the rolling area can be guided, so as to ensure that the pressure vessel raw material can be uniformly curled and deformed along the preset central axis during rolling, and avoid the pressure vessel raw material from offsetting or tilting during movement, resulting in an elliptical or other non-circular shape, thereby improving the quality of pressure vessel production and the accuracy of subsequent assembly and use, and ensuring the smoothness and accuracy of the pressure vessel rolling process.

[0014] 2. While rolling the plate, the relevant staff first controls the operation of the electric telescopic rod at the discharge end through an external single-chip computer. When the telescopic end of the electric telescopic rod moves, the corresponding swing plate is pushed up by the fixed plate, and the tilted swing plate presses the curved pressure vessel raw material after rolling through the rollers thereon, thereby preventing the pressure vessel raw material from rebounding after curling. When the pressure vessel raw material is gradually rolled into a circle, the relevant staff controls the operation of the electric telescopic rod at the other end through an external single-chip computer. When the telescopic end of the electric telescopic rod moves, the corresponding swing plate is pushed up by the fixed plate, and the tilted swing plate presses the moving pressure vessel raw material through the rollers thereon, thereby making the two ends of the curved pressure vessel raw material after rolling able to butt joint, solving the problem that the interface of the pressure vessel raw material rolled into a circle is too far offset and inconvenient to weld due to the rigid rebound of the material.

[0015] 3. The relevant staff controls the operation of Motor 2 and Electric Telescopic Rod 2 through an external single-chip computer. The driven roller extends through the telescopic end of Electric Telescopic Rod 2 to realize the lifting movement, thereby pressing the pressure vessel material upward. At the same time, due to the friction between the active roller, the driven roller and the metal plate, the active roller rotates at a uniform speed under the rotation of the output shaft of Motor 2, so that the plate material for the pressure vessel moves forward and bends continuously while being compressed. The relevant staff only needs to adjust the extension degree of Electric Telescopic Rod 2 to adjust the height position of the driven roller, thereby changing the bending radius of the plate material for the pressure vessel at the pressure point, thereby completing the rolling operation of different curvatures.

[0027] like Figure 1-4 As shown, the support assembly includes a rectangular opening arranged in the middle of the upper right end of the frame 100, and a support seat 600 is rotatably connected in the rectangular opening. The support hole arranged at the upper end of the support seat 600 is matched with the right end of the active roller 500. A mounting seat 601 is provided at the upper end of the right surface of the support seat 600 and the lower end of the right surface of the frame 100.

The upper end of the telescopic end of the electric telescopic rod three 602 is rotatably connected to the inner cavity of the mounting seat 601 at the upper end, and the electric telescopic rod three 602 is electrically connected to an external single-chip computer.

[0028] The working principle of a plate rolling device for pressure vessel production provided by the utility model is as follows: first, the relevant staff inserts one end of the pressure vessel raw material between the active roller 500 and the two driven rollers 503 in a group, and then the relevant staff adjusts the operation of the motor 304 through the external single-chip microcomputer, and the rotation of the external single-chip microcomputer output shaft drives the corresponding bidirectional screw rod 303 to rotate synchronously, and the bidirectional screw rod 303 drives the corresponding sliding block 301 and the guide roller 302 to move synchronously along the slide groove 300 during the rotation process, and finally the guide roller 302 clamps the left and right sides of the pressure vessel raw material. At the same time, following the actual situation of curling and deformation of the pressure vessel raw material after rolling, the relevant staff first adjusts the electric telescopic motor at the discharge end through the external single-chip microcomputer The rod 201 is operated, and when the telescopic end of the electric telescopic rod 201 moves, the corresponding swing plate 200 is pushed up by the fixed plate 202 to tilt up, so that the pressure vessel raw material in translation, the pressure vessel raw material in an arc state after rolling, and the tilted end of the pressure vessel raw material that has not entered the rolling area can be guided, so as to ensure that the pressure vessel raw material can be uniformly curled and deformed along the preset central axis during rolling, and avoid the pressure vessel raw material from being offset or tilted during movement to cause an elliptical or other non-circular shape, thereby improving the quality of pressure vessel production and the accuracy of subsequent assembly and use, and ensuring the stability and accuracy of the pressure vessel rolling process. After that, the relevant staff controls the motor 2505 and the electric telescopic rod 201 through an external single-chip microcomputer. The retracting rod 504 operates, and the driven roller 503 is extended through the telescopic end of the electric telescopic rod 504 to realize the lifting movement, so as to press the pressure vessel raw material upward. At the same time, due to the friction between the active roller 500, the driven roller 503 and the metal plate, the active roller 500 rotates at a uniform speed under the rotation of the output shaft of the motor 505, so that the plate material for the pressure vessel moves forward and bends continuously while being compressed. The relevant staff only needs to adjust the extension degree of the electric telescopic rod 504 to adjust the height position of the driven roller 503, so as to change the bending radius of the plate material for the pressure vessel at the pressure point, thereby completing the rolling operation of different curvatures. While rolling the plate, the relevant staff first adjusts the discharge end through the external single-chip microcomputer The electric telescopic rod 201 is in operation. When the telescopic end of the electric telescopic rod 201 moves, the fixed plate 202 pushes the corresponding swing plate 200 to tilt upward. The tilted swing plate 200 presses the curved pressure vessel raw material after rolling through the roller 203 thereon, thereby preventing the pressure vessel raw material from rebounding after rolling. When the pressure vessel raw material is gradually rolled into a circle, the relevant staff controls the operation of the electric telescopic rod 201 at the other end through the external single-chip computer. When the telescopic end of the electric telescopic rod 201 moves, the fixed plate 202 pushes the corresponding swing plate 200 to tilt upward. The tilted swing plate 200 presses the moving pressure vessel raw material through the roller 203 thereon, thereby enabling the two ends of the curved pressure vessel raw material to be butted against each other.The problem of the pressure vessel raw material rolled into a round shape being offset too far at the interface and inconvenient for welding due to the rigid rebound of the material is solved. When the rolling is completed, the relevant staff adjusts the external single chip computer to reset the electrical components, and then adjusts the operation of the electric telescopic rod 3 602. The telescopic end of the electric telescopic rod 3 602 retracts and drives the support seat 600 to flip outward through the upper end mounting seat 601, so that the support seat 600 is separated from the active roller 500, and the rolled pressure vessel can be taken out at this time.

[0029] like Figure 1-4 As shown, the grooves symmetrically arranged in the middle of the upper surface of the swing plate 200 are rotatably connected with rotating rollers 400 to prevent the swing plate 200 from directly contacting the pressure vessel raw material, which can greatly reduce the friction coefficient of contact with the pressure vessel raw material.

[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
