Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel pipe processing, concretely to a stainless steel water pipe straightening device. BACKGROUND

[0002] In the field of building, water supply, stainless steel water pipe is widely used because of strong corrosion resistance and long service life. In the manufacturing and processing of stainless steel water pipe, different degrees of deformation are often caused by extrusion, bending or heat treatment, affecting the straightness of the pipe and subsequent use.

[0003] The existing patent with the patent number CN221909177U proposes a stainless steel pipe straightening device, which comprises an operating table and a processing frame. One side of the operating table is provided with a double-shaft motor, a belt and a belt pulley two. One end of the double-shaft motor is provided with a rotating shaft and a cam. The operating table is connected with a lower straightening assembly, a water storage tank and a fixed frame. The water storage tank is connected with a water spray pipe and a piston booster assembly. The fixed frame is internally provided with cooling fan blades and a rotating rod. The rotating rod is connected with a belt pulley one. The processing frame is connected with the operating table. The inside of the processing frame is provided with a supporting plate and an upper straightening assembly. The processing frame is connected with a pneumatic cylinder. The upper straightening assembly is provided with a limiting rod and a buffer spring at each corner of one end.

[0004] Through the above setting, the pneumatic cylinder extrudes the buffer spring of the upper straightening assembly, thereby increasing the buffering effect and avoiding damage to the steel pipe caused by excessive extrusion. In addition, the double-shaft motor, the belt pulley two, the belt pulley one and the rotating rod drive the cooling fan blades to rotate, thereby cooling the steel pipe during straightening. While the rotating shaft rotates, the cam extrudes the piston booster assembly, thereby pressurizing the inside of the water storage tank. The cooling liquid in the water storage tank is sprayed out through the water spray pipe, and the cooling effect is further increased in cooperation with the action of the cooling fan blades, thereby avoiding the formation of regular undulating small waves on the surface of the steel pipe when the temperature is too high or the pressure is too large during straightening, so as to ensure the flatness and quality of the pipe.

[0005] However, the existing technical solution has the following defects when in operation:

[0006] (1) In the existing technical solution, while the rotating shaft rotates, the cam extrudes the piston booster assembly, thereby pressurizing the inside of the water storage tank. The cooling liquid in the water storage tank is sprayed out through the water spray pipe to cool the stainless steel. However, the water spray pipe only sprays one side of the steel pipe, and the cooling liquid is concentrated on the same side, which can cause the steel pipe to be heated asymmetrically and produce new deformation. In addition, one side of the steel pipe is rapidly cooled, and the other side remains at high temperature, which can easily cause warping or cracking.

[0007] (2) the prior art, the cooling liquid in the water storage tank is sprayed through the water spraying pipe, and the cooling effect is further increased by cooperating with the cooling fan blade, but the airflow of the cooling fan blade blows away the cooling liquid, reduces the adhesion effect of the liquid, and further reduces the cooling effect. Practical new type content

[0009] To solve the above technical problem, the utility model provides the following technical scheme:

[0010] A stainless steel water pipe straightening device, including operation platform and operation frame, the upper end surface of operation platform is provided with lower straightening roller, the operation frame is provided with upper straightening roller, one side of operation frame is provided with double shaft motor, one end of double shaft motor is equipped with pivot, and one end of pivot is fixedly connected with lower straightening roller, the outer wall of pivot is fixedly connected with cam, the lower end surface of operation platform is provided with water tank, the water tank is equipped with cooling liquid, the water tank is equipped with piston booster assembly, the other end of double shaft motor is fixedly connected with first belt pulley, one side of operation frame and located right above double shaft motor is provided with cooling fan, and one end of the outer wall of the pivot of cooling fan is fixedly connected with second belt pulley, and the first belt pulley and second belt pulley are equipped with belt, the operation platform is fixedly connected with water spraying pipe, the other end of water spraying pipe extends into water tank, and the water spraying pipe is fixedly connected with annular water pipe that is communicated with water spraying pipe between two water spraying pipes, a plurality of water spraying heads are arranged on the annular water pipe, the outer wall of water spraying pipe is provided with protection assembly for preventing cooling liquid from splashing elsewhere, and the operation platform is provided with recovery assembly for recycling cooling liquid.

[0011] The working principle and beneficial effects of the utility model are as follows:

[0012] 1. Working principle: when the stainless steel water pipe needs to be straightened, turn on the power, (start the air cylinder, drive the upper straightening assembly down through the air cylinder, make the upper straightening assembly extrude the buffer spring, and then increase the buffering effect), the bracket is a citation of the prior art, this application file does not make detailed description, at the same time, start the double shaft motor, one end of the double shaft motor drives the rotating shaft to rotate the lower straightening roller, through the cooperation of the upper straightening roller and the lower straightening roller, the stainless steel water pipe is straightened, when the rotating shaft rotates, it also drives the cam fixed to the outer wall to rotate, the rotation of the cam will extrude the piston booster assembly to pressurize the water tank, the piston booster assembly is a prior art, this application file does not make detailed description, as the air pressure in the water tank increases, the coolant in the water tank is sprayed out along the water spray pipe, the annular water pipe and the water spray head in turn, and the stainless steel water pipe is cooled, the residual coolant after cooling the stainless steel water pipe flows into the recovery assembly through the protection assembly, and then enters the water tank again after being filtered by the recovery assembly, which can be recycled, at the same time, the other end of the double shaft motor drives the first pulley to rotate, since the first pulley and the second pulley are connected by a belt, the rotation of the first pulley drives the second pulley to rotate through the belt, and the rotation of the second pulley drives the rotating shaft of the cooling fan to rotate, so that the cooling fan rotates to blow and cool the stainless steel water pipe.

[0013] 2. Beneficial effects:

However, the water spray pipe only sprays one side of the steel pipe, and the coolant concentrates on the same side, which can cause the steel pipe to be heated asymmetrically and produce new deformation. Moreover, one side of the steel pipe is rapidly cooled, and the other side remains high temperature, which can easily cause warping or cracking. The present scheme solves the technical problems of the prior art by symmetrically arranging the water spray pipes and fixedly connecting the annular water pipe between the water spray pipes.
