Description

Technical Field

[0001] The invention relates to the field of rust removal devices, in particular to an outer wall rust removal device suitable for steel pipes with different diameters. Background Art

[0002] During the hot forming process, carbon ash will be precipitated from the steel pipe and attached to the outer wall of the steel pipe. At the same time, when the steel pipe encounters rain during transportation or is placed in a humid place outdoors, rust will form. When the steel pipe is mechanically processed, the carbon ash and rust will fall into the transmission mechanism of the machine tool, damaging the machine tool accuracy. At the same time, cleaning the pollution also requires manpower and time. In addition, the presence of these two substances affects the workshop environment and does not meet the workshop 5S management requirements.

[0003] A Chinese patent with publication number CN209439957U discloses a rapid rust removal device for the outer wall of seamless steel pipe processing, including a bottom plate and a support plate. A first motor is installed on the left side of the support plate. A rotating shaft is connected to the right side of the first motor. A rotating frame is installed on the right end of the rotating shaft. A mounting block is symmetrically installed on the right side of the rotating frame. A screw is installed between the two mounting blocks. The thread on the screw has two sections. The spiral directions of the two sections are set oppositely. The two sections of the thread are symmetrically set along the center of the screw. Two screw sleeves are installed on the screw. A cross bar is installed on the outer wall of the screw sleeve. A brush is installed on the opposite side of the two cross bars. By installing the screw on the rotating frame and setting the screw so that the two sections of the thread are set oppositely, the rotation of the screw can drive the screw sleeve to move, and finally the adjustment of the cross bar and the brush on the cross bar can be achieved, so that the rust removal operation of steel pipes of different diameters can be achieved.

[0004] This solution has the following defects:

[0005] 1. The crossbar needs to be adjusted manually according to the diameter of the steel pipe, which is cumbersome to operate, affects the rust removal efficiency, and cannot achieve automatic operation;

[0006] 2. The brush area is too large, which makes it easy for rust and carbon ash to accumulate in the brush, affecting the rust removal effect. In addition, the excess rust and carbon ash cleaned out are not collected, affecting the working environment and making the transmission mechanism easily stuck by rust. Summary of the invention

[0007] The purpose of the present invention is to overcome the defects of the above-mentioned prior art that the cross bar needs to be manually adjusted according to the diameter of the steel pipe and the brush is prone to accumulate debris, and to provide an outer wall rust removal device suitable for steel pipes with different diameters.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A device for removing rust from the outer wall of steel pipes with different diameters, comprising a transmission roller, an inclined wheel group, a transmission roller driving assembly, a base, a vertical moving module, a grinding and rust removal mechanism, an exhaust pipe unit and a control cabinet for controlling the entire device, wherein the transmission roller and the inclined wheel group are both mounted on the base, the transmission roller and the inclined wheel group are arranged in parallel, a gap for supporting the steel pipe is formed between the transmission roller and the inclined wheel group, and the inclined wheel group comprises a plurality of inclined wheel units capable of adjusting the angle of the base;

[0017] Furthermore, both ends of the convex surface of the arc-shaped circular tube are also connected to vertical circular tubes, and the electric push rod bracket is provided with a through hole for allowing the vertical circular tube to move up and down and limiting its horizontal position.

[0018] Furthermore, the bevel wheel unit includes a rotating wheel and a rotating wheel mounting seat, the rotating wheel mounting seat is connected to the center of the rotating wheel, the front and rear ends of the rotating wheel mounting seat are each provided with a first fixing hole, the base is correspondingly provided with a second fixing hole and an arc-shaped through hole, the second fixing hole cooperates with the first fixing hole at one end of the rotating wheel mounting seat, the arc-shaped through hole cooperates with the first fixing hole at the other end of the rotating wheel mounting seat, the number of the second fixing hole is one, and the rotating wheel mounting seat is rotatably connected to the base through the first fixing hole, the second fixing hole and the arc-shaped through hole.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] (1) The present invention uses a combination of a transmission roller and an inclined wheel group to drive the steel pipe to rotate. The inclined wheel unit with an adjustable base angle is tilted in the same direction during the rotation of the steel pipe, so that the steel pipe moves forward, thereby achieving the effect of supporting the steel pipe and driving the steel pipe to rotate and move forward. There is no need to continuously fix a certain part of the steel pipe, and the outer surface of the steel pipe can be rust-free. In addition, the steel pipe is easy to install and only needs to be placed on the transmission roller and the inclined wheel group.

[0026] The grinding and rust removal mechanism is installed above the steel pipe through a vertical moving module and a module bracket. The position of the steel pipe can be detected by the steel pipe detection component, so that the grinding and rust removal mechanism contacts the surface of the steel pipe during rust removal. In addition, since the transmission roller and the inclined wheel group can drive the steel pipe to rotate forward, the outer surface of the steel pipe can be rust-free in all directions, and the working process is highly stable.

[0027] The vertical arrangement of the grinding and rust removal mechanism also solves the problem that traditional rust removal equipment cannot work because the transmission mechanism is stuck by rust;

[0028] By detecting the position of the steel pipe, it can realize automatic measurement and automatic positioning of the wire wheel for steel pipes of different diameters, solving the problem that traditional equipment needs to be manually adjusted according to the diameter of the steel pipe;

[0029] The present invention also adds a first travel switch and a second travel switch, which can detect the position of the steel pipe and control the rust removal action and steel pipe removal action of the entire device, which is conducive to realizing the automatic operation of the entire device and improving production efficiency.

[0030] (2) In the present invention, the combination of the driving roller and the inclined wheel group drives the steel pipe to rotate and move forward, and the grinding and rust removal mechanism can be arranged at the same vertical position, thereby forming a fixed steel pipe rust removal station. A first exhaust pipe is arranged on the same horizontal line of the steel pipe rust removal station, and dust can be removed at the rust removal source of the steel pipe without full closure, thereby shortening the working cycle of the equipment;

[0031] A second exhaust duct is provided at the lower end of the steel pipe rust removal station to further improve the dust extraction effect.

[0032] (3) The present invention further provides an electric push rod on the inner side of the second travel switch. After rust removal is completed, the steel pipe stays in a fixed position. At this time, the electric push rod slightly lifts the steel pipe to provide a grasping space, which is convenient for the robot to grasp the steel pipe. BRIEF DESCRIPTION OF THE DRAWINGS
