Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a water-cooled circulation device for steel pipe grinding. Background Art

[0002] Steel pipes are often used in industry. However, during use, the steel pipes often rust due to improper storage, lack of maintenance, or long-term exposure to the open air, which affects the safety of the steel pipe use. Therefore, rusty steel pipes need to be ground by a grinding device before being put into use.

[0003] In the existing grinding process, usually the steel pipe is placed in a grinding machine, and the guide wheels in the guiding mechanism in the grinding machine drive the steel pipe to rotate and move at high speed. A plurality of grinding wheels arranged above the guide wheels contact the surface of the steel pipe and rotate to grind the steel pipe, so as to remove rust and impurities on the surface of the steel pipe. Although this can achieve a good grinding effect, the overall installation cost of the grinding machine is also relatively high. And since the length of the steel pipe is usually long, in order to stably support the steel pipe, the guide wheels in the grinding machine are usually arranged according to the longest dimension of the processed steel pipe, but this also increases the number of installed guide wheels, further increasing the installation cost of the grinding machine. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a water-cooled circulation device for steel pipe grinding that can adjust the grinding stroke according to the length of the steel pipe.

Specific Embodiments

[0027] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0028] SeeFigures 1-6 。

[0029] The utility model discloses a water-cooled circulation device for steel pipe grinding, comprising:

[0030] A base 1;

[0031] A bearing member 2, including a first guide rail 21 arranged on the base 1. One end of the first guide rail 21 is provided with a group of bearing rods 22, and the other end is slidably provided with another group of bearing rods 22. A pair of first support wheels 23 are slidably arranged at the top of the corresponding bearing rods 22 for bearing the steel pipe 8. A corresponding first adjusting rod 24 is provided on the corresponding first support wheels 23 for adjusting the pair of first support wheels 23 to approach or move away from each other. One end of the first guide rail 21 is provided with a first power unit 25 for driving the slidable bearing rods 22 to reciprocate on the first guide rail 21;

[0032] A rotating member 3, arranged on the base 1 and at the end far from the slidable bearing rods 22, for driving the steel pipe 8 to rotate;

[0033] A grinding member 4, slidably arranged on the base 1 along the placement direction of the steel pipe 8 and arranged on one side of the bearing member 2, for grinding the steel pipe 8.

[0034] In specific implementation, the staff adjusts the distance between the bearing rods 22 and the distance between the corresponding first support wheels 23 through the first power unit 25 and the first adjusting rod 24 according to the actual length and diameter of the steel pipe 8. After adjusting the bearing rods 22 and the first support wheels 23 to appropriate positions, the steel pipe 8 is placed on the bearing member 2, and one end of the steel pipe 8 is connected to the rotating member 3. The rotating member 3 drives the steel pipe 8 to rotate on the bearing member 2, and the grinding member 4 moves along the placement direction of the steel pipe 8 and rotates and grinds the surface of the steel pipe 8.

[0035] Compared with the existing grinding machines, the utility model has a relatively simple structure and relatively low cost. By adjusting the distance between the bearing rods 22 and the distance between the first support wheels 23, the bearing member 2 can be adapted to steel pipes 8 with different lengths and diameters. And through the mutual cooperation of the bearing member 2, the rotating member 3 and the grinding member 4, there is no need for the staff to add other structures according to the length of the steel pipe 8.

[0036] Preferably, the first power unit 25 can adopt a linear module in the prior art.

[0037] In one embodiment, the grinding component 4 includes a second guide rail 46 disposed on the base 1. An electric telescopic rod 41 is slidably disposed on the second guide rail 46. A third power unit 47 is provided on one side of the second guide rail 46 for driving the electric telescopic rod 41 to reciprocate. The telescopic end of the electric telescopic rod 41 is in an inverted "J" shape, and a grinding wheel 42 is rotatably disposed on the telescopic end. The grinding wheel 42 is disposed above the bearing component 2, and there is a space for placing the steel pipe 8 between the grinding wheel 42 and the bearing component 2. A second power unit 43 is further provided on one side of the telescopic end for driving the grinding wheel 42 to rotate. A pair of second support wheels 44 are also provided on the side of the fixed end of the electric telescopic rod 41 close to the bearing component 2. A second adjusting rod 45 is disposed on the second support wheels 44 for adjusting the second support wheels 44 to approach or move away from each other simultaneously.

[0038] With such a design, before grinding the steel pipe 8, the height of the grinding wheel 42 and the distance between the second support wheels 44 are adjusted by adjusting the electric telescopic rod 41 and the second adjusting rod 45. After the grinding wheel 42 and the second support wheels 44 are adjusted to appropriate positions in contact with the steel pipe 8, the rotating component 3 cooperates with the grinding component 4 to grind the steel pipe 8. The electric telescopic rod 41 drives the grinding wheel 42 to move along the placement direction of the steel pipe 8 and grind the surface of the steel pipe 8, and the second support wheels 44 move with the grinding wheel 42 to ensure the stability of the real-time grinding part of the grinding wheel 42.

[0039] Preferably, the second power unit 43 can adopt a motor in the prior art.

[0040] Preferably, the third power unit 47 can adopt a linear module in the prior art.

[0041] In one embodiment, the rotating component 3 includes a chuck 31 disposed at one end far from the slidable bearing rod 22 for fixing one end of the steel pipe 8 and driving the steel pipe 8 to rotate. A fourth power unit 32 is provided at the end of the chuck 31 far from the steel pipe 8 for driving the chuck 31 to rotate.

[0042] With such a design, when the steel pipe 8 is fixed by the chuck 31 and driven to rotate, a rotational speed difference is formed between the rotational speed of the steel pipe 8 and the rotational speed of the grinding wheel 42, thereby improving the grinding efficiency of the grinding wheel 42.

[0043] Preferably, the fourth power unit 32 can adopt a motor in the prior art.

[0044] In one embodiment, a water storage cavity 11 is provided in the base 1, and cooling water is contained in the water storage cavity 11;

[0045] One side of the base 1 is provided with a cooling component 5, which includes a hose 51 arranged at one end of the base 1 close to the rotating component 3. One end of the hose 51 is connected to the water storage cavity 11 of the base 1, and the other end is connected to a water spray gun 52. The water outlet of the water spray gun 52 is aligned with the grinding point between the grinding wheel 42 and the steel pipe 8 for cooling the steel pipe 8.

[0046] With such a design, during the grinding process of the steel pipe 8, a large amount of heat will be generated due to friction. In order to prevent the surface temperature of the steel pipe 8 from being too high, when the grinding component 4 is working, the water spray gun 52 continuously sprays water at the grinding point to control the temperature of the surface of the steel pipe 8.

[0047] It should be noted that the hose 51 has a sufficient length to support the reciprocating movement of the electric telescopic rod 41 on the second guide rail 46.

[0048] In an embodiment, an adjusting component 6 is provided on the electric telescopic rod 41. The adjusting component 6 includes a support rod 61 arranged on one side of the telescopic end of the electric telescopic rod 41. The support rod 61 can be freely bent, and further includes a hinge ball 62 arranged at the other end of the support rod 61. The hinge ball 62 is ball-jointed with the support rod 61, and a fixing ring 63 is also connected to the hinge ball 62 for fixing and adjusting the angle of the water spray gun 52.

[0049] With such a design, the staff can adjust the adjusting component 6 according to the actual grinding situation of the steel pipe 8 to change the water spraying angle and orientation of the water spray gun 52 at the grinding point, so that the cooling water can be sprayed more precisely on the grinding point.

[0050] It should be pointed out that there is sufficient friction between the hinge ball 62 and the support rod 61, so that the hinge ball 62 will not displace relative to the support column without external interference.

[0051] In an embodiment, a limiting component 7 is provided at one end of the steel pipe 8 far from the rotating component 3. The limiting component 7 includes a limiting rod 71 arranged on the slidable bearing rod 22. One end of the limiting rod 71 has an arc-shaped cross-section and extends into the inner wall of the steel pipe 8. And a plurality of rolling balls 72 are evenly distributed on the bottom surface of the end of the limiting rod 71 extending into the inner wall of the steel pipe 8. The rolling balls 72 are in rolling contact with the inner wall of the steel pipe 8 for restricting the shaking of the steel pipe 8.

[0052] With such a design, when the steel pipe 8 is too long, during the process of the chuck 31 driving the steel pipe 8 to rotate, one end of the steel pipe 8 far from the chuck 31 will shake. The limiting rod 71 and the rolling balls 72 restrict the shaking amplitude of the steel pipe 8 on the premise of not interfering with the rolling of the steel pipe 8.

[0053] In an embodiment, a plurality of sedimentation ponds 12 are provided on the base 1. A plurality of small holes are opened at the bottom of the sedimentation ponds 12 for recycling and filtering the cooling water.

[0054] With such a design, when the cooling component 5 cools the grinding point, the cooling water will carry the debris generated during grinding and flow into the sedimentation tank 12. The small holes in the sedimentation tank 12 intercept the larger debris, causing the debris to remain at the bottom of the sedimentation tank 12. The cooling water flowing into the sedimentation tank 12 flows back to the water storage chamber 11 through the small holes for reuse.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention. In addition, "a plurality of", "multiple groups", and "several" mean more than two.
