Description

Technical Field

[0001] This utility model belongs to the field of crimping fixture technology, and relates to stiffening rings, particularly an adjustable stiffening ring hydraulic crimping fixture. Background Technology

[0002] The stiffening ring crimping fixture is a key piece of equipment specifically designed for the manufacturing process of pressure steel pipes. Its main function is to ensure the safety and stability of pipelines under high-pressure environments by connecting and reinforcing the pipes. As a reinforcing structure, the stiffening ring effectively disperses pressure and improves the load-bearing capacity of the steel pipe. In the production of pressure steel pipes, the stiffening ring crimping fixture forms a robust connection by tightly bonding the stiffening ring to the surface of the steel pipe. This process not only enhances the overall strength of the pipeline but also prevents deformation or rupture caused by pressure. Furthermore, the application of this fixture reduces human error during welding and connection processes, ensuring the uniformity and stability of product quality.

[0003] However, most existing stiffening ring pressing tools press the same stiffening ring at the same location. However, because the stiffening ring positions of each pressure steel pipe are inconsistent during welding, the pressing tool needs to be frequently replaced, resulting in low overall work efficiency. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing an adjustable stiffening ring hydraulic pressing fixture. The technical problem this utility model aims to solve is that because the stiffening ring positions of each pressure steel pipe are inconsistent, the pressing fixture needs to be frequently replaced during use, resulting in low overall work efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An adjustable stiffening ring hydraulic crimping fixture includes an inner plate, an outer plate on one side of the inner plate, and a top plate fixedly connected to the top of the inner and outer plates. A limiting groove is formed on one side of the outer plate, and a support block is slidably connected inside the limiting groove. A lifting mechanism for raising and lowering the support block is provided on the top of the support block. Two second hydraulic rods are fixedly connected to one side of the support block, and a pressure plate is fixedly connected to the surface of the two second hydraulic rods near the inner plate. A pressure groove is formed on the surface of the pressure plate near the inner plate, and multiple pressure rollers are rotatably connected inside the pressure groove. The multiple pressure rollers are evenly arranged in an arc shape.

[0007] The working principle of this utility model is as follows: a support block is installed on one side of the outer plate, and a pressure plate is installed on one side of the support block. Since the pressure plate is connected to the support block through a second hydraulic rod, the second hydraulic rod can be activated when the stiffening ring needs to be pressed. Since the support block is slidably set, the height of the pressure plate can be adjusted according to the height of the stiffening ring.

[0008] The lifting mechanism includes a connector, which is fixedly connected to the top of the top plate. Two first auxiliary wheels are symmetrically rotatably connected to the top of the top plate. A take-up roller is rotatably connected to one side of the connector. A pull rope is sleeved on the surface of the take-up roller. The other end of the pull rope is fixedly connected to the top of the support block. A motor is fixedly connected to one side of the connector. The take-up roller is fixedly connected to the output shaft of the motor. A moving mechanism for moving the inner plate is provided on the surface of the inner plate near the outer plate.

[0009] The above structure ensures that the support block can drive the pressure plate to move up and down.

[0010] The moving mechanism includes four second auxiliary wheels, all of which are rotatably connected to one side of the inner plate and are evenly arranged in a square shape. The outer plate is rotatably connected to a third auxiliary wheel on the surface near the four second auxiliary wheels, and the four third auxiliary wheels are arranged in pairs. The surfaces of the two sets of third auxiliary wheels away from the second auxiliary wheels are provided with adjustment mechanisms for adjusting the third auxiliary wheels.

[0011] The above structure ensures that the machine can move stably.

[0012] The adjustment mechanism includes a connecting plate, which is disposed on one side of the two third auxiliary wheels. Two first hydraulic rods are fixedly connected to the surface of the connecting plate away from the third auxiliary wheels, and both first hydraulic rods are fixedly connected to one side of the outer plate.

[0013] The above structure allows for adjustment of the auxiliary wheel, ensuring that it makes close contact with the pipe.

[0014] Compared with the prior art, the adjustable stiffening ring hydraulic pressing fixture of this utility model has the following advantages:

[0015] 1. This utility model adopts a technical solution where the pressure plate moves up and down via a support block. This ensures that the tooling can press the stiffening rings at different positions, effectively solving the problem of inconsistent stiffening ring positions on each pressure steel pipe, which leads to frequent replacement of the pressing tool and low overall work efficiency. A pull rope is installed on the top of the support block, and the other end of the pull rope is connected to the take-up roller. A motor is installed on the top of the outer plate, and the motor is mounted on the side of the take-up roller. When the motor drives the take-up roller to rotate, the height of the support block can be adjusted, thus ensuring that the height of the pressure plate can be adjusted according to the height of the stiffening ring.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1-4As shown, an adjustable stiffening ring hydraulic pressing fixture includes an inner plate 1, an outer plate 101 on one side of the inner plate 1, and a top plate 102 fixedly connected to the top of the inner plate 1 and the outer plate 101. A limiting groove 106 is opened on one side of the outer plate 101, and a support block 203 is slidably connected inside the limiting groove 106. A lifting mechanism for raising and lowering the support block 203 is provided on the top of the support block 203. Two second hydraulic rods 204 are fixedly connected to one side of the support block 203. The same pressure plate 205 is fixedly connected to the surface of the two second hydraulic rods 204 near the inner plate 1. A pressing groove 206 is opened on the surface of the pressure plate 205 near the inner plate 1. Multiple pressure rollers 207 are rotatably connected inside the pressing groove 206. By setting the pressure rollers 207, the pressure plate 205 can also move during the pressing process. The multiple pressure rollers 207 are evenly arranged in an arc shape. By setting the support block 203, it can be ensured that the fixture can press the stiffening ring at different positions.

[0023] Preferably, the lifting mechanism includes a connector 104, which is fixedly connected to the top of the top plate 102. Two first auxiliary wheels 103 are symmetrically rotatably connected to the top of the top plate 102. A take-up roller 201 is rotatably connected to one side of the connector 104. A pull rope 202 is sleeved on the surface of the take-up roller 201. The other end of the pull rope 202 is fixedly connected to the top of the support block 203. A motor 2 is fixedly connected to one side of the connector 104. The take-up roller 201 is fixedly connected to the output shaft of the motor 2. A moving mechanism for moving the inner plate 1 is provided on the surface of the inner plate 1 near the outer plate 101. The support block 203 can be raised and lowered by the take-up roller 201.

[0024] Furthermore, the moving mechanism includes four second auxiliary wheels 105, all of which are rotatably connected to one side of the inner plate 1. The four second auxiliary wheels 105 are evenly arranged in a square shape. The outer plate 101 is rotatably connected to a third auxiliary wheel 107 on the surface of the side of the outer plate 101 closest to the four second auxiliary wheels 105. The four third auxiliary wheels 107 are arranged in pairs. The surfaces of the two sets of third auxiliary wheels 107 furthest from the second auxiliary wheels 105 are provided with adjustment mechanisms for adjusting the third auxiliary wheels 107.

[0025] Furthermore, the adjustment mechanism includes a connecting plate 108, which is disposed on one side of the two third auxiliary wheels 107. Two first hydraulic rods 109 are fixedly connected to the surface of the connecting plate 108 away from the third auxiliary wheels 107, and both first hydraulic rods 109 are fixedly connected to one side of the outer plate 101.

[0026] The working principle of this utility model is as follows: In use, the fixture is first placed on top of the pressure steel pipe. A first hydraulic rod 109 is installed on one side of the outer plate 101, and a third auxiliary wheel 107 is installed on one side of the first hydraulic rod 109. After the fixture is placed, the first hydraulic rod 109 is activated, allowing the third auxiliary wheel 107 to make tight contact with the pressure pipe, thus preventing the fixture from loosening during the pressing process. A support block 203 is installed on one side of the outer plate 101, and a pressure plate 205 is installed on one side of the support block 203. Because the pressure plate 205... The support block 203 is connected to the second hydraulic rod 204. So when the stiffening ring needs to be pressed, the second hydraulic rod 204 can be activated. A pull rope 202 is installed on the top of the support block 203, and the other end of the pull rope 202 is connected to the take-up roller 201. A motor 2 is installed on the top of the outer plate 101, and the motor 2 is installed on one side of the take-up roller 201. So when the motor 2 drives the take-up roller 201 to rotate, the height of the support block 203 can be adjusted, thereby ensuring that the height of the pressure plate 205 can be adjusted according to the height of the stiffening ring.

[0027] In summary, in this utility model, a support block is installed on one side of the outer plate, and a pressure plate is installed on one side of the support block. Since the pressure plate is connected to the support block through a second hydraulic rod, the second hydraulic rod can be activated when the stiffening ring needs to be pressed. A pull rope is installed on the top of the support block, and the other end of the pull rope is connected to the take-up roller. A motor is installed on the top of the outer plate, and the motor is installed on the side of the take-up roller. Thus, when the motor drives the take-up roller to rotate, the height of the support block can be adjusted, thereby ensuring that the height of the pressure plate can be adjusted according to the height of the stiffening ring.
