Steel pipe end grinding and slag cleaning machine

technical field

The utility model relates to steel pipe end grinding equipment, in particular to a steel pipe end grinding and slag cleaning machine for removing splashes sticking to the steel pipe surface during plasma cutting operations.

Background technique

At present, in the production of spiral welded pipes, the cut-to-length steel pipes are completed by plasma cutting. During the cutting process, the molten metal is blown by the airflow to the inner wall of the steel pipes to form splash stickies. All debris should be removed to avoid pitting or other external defects at the pipe ends. The current removal of splashed sticky matter at the pipe end is done by manual grinding by production personnel, which has high labor intensity, low work efficiency, and poor grinding quality.

Contents of the invention

The purpose of this utility model is to solve the above problems, and provide a steel pipe end grinding and slag cleaning machine that can replace manual grinding and efficiently remove sticky matter splashed at the end of the pipe generated during plasma cutting production operations.

The technical solution to achieve the above purpose is: a steel pipe end grinding and slag cleaning machine, including a rail trolley assembled on the longitudinal rail, the driving wheel shaft of the rail trolley is equipped with a trolley-driven deceleration motor; the rail trolley is provided with a pair of Horizontally arranged linear slide rails, the sliders of the two linear slide rails are fixedly connected to the bottom plate arranged on it, and the grinding wheel drive reduction motor is installed on the bottom plate, and the output shaft of the grinding wheel drive reduction motor is connected to a The longitudinally arranged grinding wheel shafts are connected, and the middle part of the grinding wheel shaft is equipped with a shaft support, which is fixed on the top of the bottom plate, and the front end of the grinding wheel shaft is equipped with a grinding wheel; A cylinder base is fixedly arranged by bolt connection, and a horizontally arranged cylinder is installed on the cylinder base, and the telescopic rod of the cylinder is hingedly connected with the base plate.

The above-mentioned steel pipe end grinding and slag cleaning machine is provided with horizontally arranged cylinder base assembly bolt holes on the top of the rail trolley.

In the aforementioned steel pipe end grinding and slag cleaning machine, the grinding wheel is a steel wire wheel.

This steel pipe end grinding and slag cleaning machine is used in the spiral welded pipe processing production line, and has the following advantages:

1. The grinding effect is good, especially the spatters that are firmly separated and bonded;

2. The sliding friction between the grinding wheel and the steel pipe is controllable;

3. The grinding wheel has good floatability, which ensures the constant contact between the grinding wheel and the steel pipe;

4. The power of the grinding wheel adopts the motor reducer, which not only increases the torque of the grinding wheel, but also reduces the power of the motor. At the same time, it can adapt to a wider range of cylinder pressure and improve the grinding efficiency;

5. It can meet the production of different pipe diameters and is easy to adjust;

6. The equipment is simple and reliable, easy to operate, and can be automated.

detailed description

The specific embodiment of the utility model will be described in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, this steel pipe end grinding and slag cleaning machine has a track trolley 1. The track trolley 1 is mainly composed of a driving wheel set, a passive wheel set and a trolley platform. on longitudinal rails. One end of the driving wheel shaft of the rail trolley 1 is equipped with a trolley-driven reduction motor 2 for driving the active wheel set to rotate, to provide sufficient feed power for the rail trolley when feeding, and to provide sufficient reverse power when reversing. A pair of horizontally arranged linear slide rails 3 are fixedly installed above the trolley platform of the rail trolley 1, and the sliders of the two linear slide rails 3 are fixedly connected with the base plate 4 arranged on it, and the base plate 4 is passed through bolts. Connect and fixedly install the grinding wheel drive deceleration motor 5, the output shaft of the grinding wheel drive deceleration motor 5 is connected coaxially with a longitudinally arranged grinding wheel shaft 7 through an elastic coupling 6, and the middle part of the grinding wheel shaft 7 is equipped with a shaft support 8 , the shaft support 8 is fixed on the top of the base plate 4 through bolt connection, and the front end of the grinding wheel shaft 7 is equipped with a grinding wheel 9. The grinding wheel 9 can be a grinding wheel, but in order to ensure that only the oxidation sticking to the steel pipe surface is removed. Skin and cutting spatter without damaging the steel pipe wall, the utility model is preferably a steel wire wheel. Above the trolley platform of described track trolley 1, the cylinder base 10 of right-angle plate type is fixedly set by bolt connection on one side, and the cylinder 11 of horizontal arrangement is fixedly installed on this cylinder base 10, and the front end of telescoping rod of this cylinder 11 and described The bottom plate is connected by 4 hinges. As in the embodiment of the drawings, the cylinder 11 is arranged in the middle of the two linear slide rails 3 , and the hinge connection point with the bottom plate 4 is on one side of the bottom plate 4 .

As shown in Figure 2, this steel pipe end grinding and slag cleaning machine is provided with two rows of cylinder base assembly bolt holes 12 arranged horizontally above the trolley platform of the rail trolley 1, and by changing the cylinder base 10 and the cylinder base assembly bolt holes 12 in different positions The combination can realize the grinding of different pipe diameters.

The steel pipe end grinding and slag removal machine cooperates with the pipe turning machine to complete the grinding and slag removal work of the steel pipe end. First, the rotating roller of the pipe turning machine drives the steel pipe to rotate, and the trolley drives the deceleration motor 2 to drive the rail trolley 1 to the pipe end, and the grinding wheel drives the deceleration motor. 5. The elastic coupling 6 drives the grinding wheel 9 to rotate, and the air cylinder 11 pushes the bottom plate 4 to move on the linear slide rail 3, so that the grinding wheel 9 moves to the inner side of the steel pipe where the rotating roller contacts the steel pipe and presses the side of the steel pipe The wall is polished and the grinding effect can be adjusted and the grinding time can be controlled by adjusting the air intake pressure of the cylinder. When the splashed sticky matter within the width range of the grinding wheel 9 wire brush is cleaned, the track trolley 1 will move forward for a suitable distance and proceed to the next stage. Grinding, until the grinding distance required by the process is completed, after the grinding is completed, the working cylinder 11 returns, the grinding wheel 9 and the rotating roller of the tube turning machine stop, and the rail trolley 1 retreats to a safe distance to complete a grinding process.
