Description

Technical Field

[0001] The utility model relates to the technical field of cold-drawn rectangular tube grinding, in particular to a device for grinding and polishing a tube mouth of a cold-drawn rectangular tube. Background Art

[0002] Cold drawn rectangular tube is a hollow long steel strip, which is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

[0003] At present, when a cold-drawn rectangular tube is welded with another set of rectangular tubes or other components, in order to ensure a good connection surface of the rectangular tube mouth, workers usually push the tube mouth of the rectangular tube through a wire wheel grinder to grind the tube mouth surface of the rectangular tube with the wire wheel. However, when workers manually operate the cold-drawn rectangular tube to pass the wire wheel, the hand-pushed and grinded cold-drawn rectangular tube is prone to shaking, resulting in poor effect of grinding the cold-drawn rectangular tube mouth. For this reason, we propose a device for grinding and polishing the tube mouth of a cold-drawn rectangular tube. Utility Model Content

[0004] The main purpose of the utility model is to provide a device for grinding and polishing the tube mouth of a cold-drawn rectangular tube. A pushing mechanism is arranged at a material seat of a grinder body. The pushing mechanism is assembled at the material seat to form a structure that can press and clamp the cold-drawn rectangular tube and bring it close to the wire wheel above the grinder body for grinding. The cold-drawn rectangular tube can be pressed and clamped to be close to the wire wheel of the grinder body for grinding and polishing at its own tube mouth, thereby ensuring that there is a mechanical pressing and clamping pushing structure when the tube mouth of the cold-drawn rectangular tube is ground, thereby ensuring that the tube mouth of the cold-drawn rectangular tube is ground stably. Furthermore, when the cold-drawn rectangular tube is pressed and clamped for grinding and polishing, there is no need for workers to hold the cold-drawn rectangular tube, thereby reducing the operating fatigue of workers when grinding the tube mouth of the cold-drawn rectangular tube. At the same time, when the cold-drawn rectangular tube is mechanically pressed and clamped, it can pass through the wire wheel horizontally when the tube mouth is ground, thereby ensuring that the tube mouth of the cold-drawn rectangular tube is ground with high finish, thereby effectively solving the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The U-shaped support plate is connected to the extension plate of the L-shaped support plate, and the extension plate is connected to the extension plate of the L-shaped support plate by a screw thread, and the extension plate is connected to the extension plate of the L-shaped support plate by a screw thread.

[0007] Furthermore, the telescopic rod head of the electric push rod is welded with a connecting plate, and bolts are screwed between the connecting plate and the plate body of the side connecting plate;

[0008] By adopting the above technical solution, the electric push rod can be connected to the side connecting plate by means of the connecting plate, and then the electric push rod moves above the guide groove with the U-shaped supporting plate by means of the connecting plate and the side connecting plate.

[0009] Furthermore, the block width of the guide block is the same as the groove width of the guide groove;

[0010] By adopting the above technical solution, the U-shaped support plate and the guide block can perform guided linear motion in the guide groove.

[0011] Furthermore, the plate diameter of the pressure plate is the same as the plate width of the U-shaped support plate;

[0012] By adopting the above technical solution, after the cold-drawn rectangular tube is placed on the surface of the U-shaped support plate, the pressure plate can press the cold-drawn rectangular tube onto the U-shaped support plate.

[0013] Furthermore, a spacing distance is reserved between the U-shaped support plate and the wire wheel;

[0014] By adopting the above technical solution, when the U-shaped support plate carries the cold-drawn rectangular tube through the wire wheel for grinding and polishing, the wire wheel will not rub the U-shaped support plate.

[0015] Furthermore, the length of the rod body of the screw is greater than the length of the frame plate of the L-shaped frame plate, and the end surface of the lower rod body of the screw is welded to the upper cone head plate of the pressure plate;

[0016] By adopting the above technical solution, the screw can be rotated downward from the spinning hole of the L-shaped frame plate to the U-shaped support plate, so that the pressure plate can press the cold-drawn rectangular tube onto the surface of the U-shaped support plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model provides a pushing mechanism at the material seat of the grinder body, and the pushing mechanism is assembled at the material seat to form a structure that can press and clamp the cold-drawn rectangular tube close to the wire wheel above the grinder body for grinding, so that the cold-drawn rectangular tube can be close to the wire wheel of the grinder body for grinding and polishing at its pipe mouth in a pressed and clamped state, thereby ensuring that there is a mechanical pressing and clamping pushing structure when the cold-drawn rectangular tube is ground at the pipe mouth, thereby ensuring that the cold-drawn rectangular tube is ground at the pipe mouth stably.

[0019] In addition, when the cold-drawn rectangular tube is clamped for grinding and polishing, workers do not need to hold the cold-drawn rectangular tube, which can reduce the operating fatigue of workers when grinding the tube mouth of the cold-drawn rectangular tube. At the same time, the cold-drawn rectangular tube clamped by the machine can pass through the wire wheel horizontally when grinding the tube mouth, ensuring the high-smoothness grinding of the cold-drawn rectangular tube mouth.
