Description

Technical Field

[0001] The invention belongs to pipe production equipment, in particular to small pipe production equipment. Background Art

[0002] As the country continues to carry out infrastructure construction, the demand for plates is increasing. In order to meet the usage requirements in different environments, the plates need to undergo multiple and complex processing steps, such as heat treatment, cutting, splitting, etc. The winding mechanism is to wind the tube material to facilitate the movement and transportation of long strips of material and reduce the floor space occupied by the long strips of material.

[0003] At present, when a tube is coiled by a coiling mechanism available on the market, the head of the tube is generally bent so that the tube is fixed on the coiling mechanism. This requires that the bent portion of the tube be straightened or cut off when in use, resulting in material waste and reduced work efficiency. In addition, the coiling mechanism currently available on the market does not have a component for pressing the end of the tube, so that after the coil is coiled, the end of the tube is warped, which is inconvenient to handle and transport.

[0004] Rolling is a pressure processing method in which a metal billet is passed through the gap between a pair of rotating rollers. Due to the compression of the rollers, the cross-section of the material is reduced and the length is increased. This is the most commonly used production method for steel, mainly used to produce profiles, plates and pipes.

[0005] At present, when the plate is cold rolled, there is no limiting device on both sides of the plate, which makes the edges of the plate irregular after being squeezed by the rollers, causing certain difficulties for the subsequent winding. It is necessary to add a process to regularize the edges of the plate, resulting in relatively low production efficiency. Summary of the Invention

[0006] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a small tube material production equipment for improving the rolling quality of small tube material plates and improving the efficiency of coiling the rolled plates.

The cold-rolled plate is annealed by the heat treatment device B to remove the internal stress of the cold-rolled plate, and then the rolled plate is wound by the winding device A, thereby improving the winding efficiency of the plate and reducing the waste rate of the plate.

[0030] The winding mechanism includes a winding frame 1, a winding power mechanism 2 and a winding disk 3. The winding power mechanism 2 and the winding disk 3 are rotatably installed on the winding frame 1. The winding disk 3 is connected to the winding power mechanism 2. A plate fixing structure 4 for fixing the end of the plate and a plate pressing structure 5 for rolling up the end of the plate are provided on the winding disk 3. The end of the plate is fixed by the arrangement of the plate fixing structure 4, replacing the traditional fixing method of fixing the plate by bending the end of the plate, thereby improving the utilization rate of the plate and effectively improving the efficiency of plate fixing; the arrangement of the plate pressing structure 5 makes it easy to roll up the end of the plate, thereby preventing the end of the plate from warping and facilitating the movement of the rolled-up plate.

[0031] The winding disk 3 includes a fixed disk surface 6 and a winding drum 7. The plate is wound by the winding drum 7. The winding drum 7 is fixedly connected to the middle of the fixed disk surface 6. The plate fixing structure 4 is rotatably connected to the winding drum 7. The plate pressing structure 5 is fixedly installed on the fixed disk surface 6.

[0032] The plate fixing structure 4 includes a connecting plate 8, a connecting plate fixing part 9 and a plate fixing part 10. The connecting plate 8 is rotatably installed on the winding drum 7. The plate fixing part 10 is slidably installed on the connecting plate 8. The connecting plate fixing part 9 is installed on the side of the connecting plate 8. The end of the plate is fixed by the plate fixing part 10, which facilitates the winding drum 7 to wind up the plate. The connecting plate 8 is fixed by the connecting plate fixing part 9, which facilitates the plate fixing part 10 to fix the plate.

[0045] The first adjustment end surface 8c and the second adjustment end surface 11c are located on the same side, so that the screws used for fixing are outside the cold-rolled forming surface, thereby improving the surface quality of the plate.

[0046] Slide blocks 12c are rotatably connected to both ends of the adjusting wheel 3c. The slider 12c is slidably installed in the cold rolling mill frame 1c. A slider lifting member 13c is also rotatably installed on the cold rolling mill frame 1c. The slider lifting member 13c is connected to the slider 12c.

[0049] The winding cooling mechanism includes a first cold material roller 15a and a second cold material roller 16a. The first cold material roller 15a and the second cold material roller 16a rotate in the same direction. A workpiece gap 17a is provided between the first cold material roller 15a and the second cold material roller 16a. The workpiece gap 17a facilitates the passage of the plate between the first cold material roller and the second cold material roller. The arrangement of the first cold material roller 15a and the second cold material roller 16a facilitates the cooling of the plate after treatment by the heat treatment device B, and the rollers can be used to slightly twist the plate to further improve the mechanical properties of the plate.

[0050] The winding cooling mechanism also includes a cooling frame 18a and a cold material roller motor 19a. The cold material roller motor 19a is slidably installed on the cooling frame 18a. The first cold material roller 15a and the second cold material roller 16a are both connected to the cold material roller motor 19a. The distance between the first cold material roller 15a and the second cold material roller 16a is adjusted by adjusting the distance between the cold material roller motors 19a, thereby adjusting the degree of torsion of the plate.
