Description

Technical Field

[0001] The present application relates to the field of pipeline cutting equipment, and in particular to a groove cutting and welding device for stainless steel elbow tee connections. Background Art

[0002] Cutting and welding equipment is a multifunctional tool, mainly used for cutting and welding of metal materials. It combines the two functions of cutting and welding and is widely used in manufacturing, construction, maintenance and other fields. Before connecting the stainless steel pipe to the elbow, the pipe needs to be cut, and in order to improve the quality and strength of subsequent welding, a groove is usually formed at the pipe cut during cutting.

[0003] The existing stainless steel elbow groove cutting and welding device generally first adjusts the cutting head up, down, left and right so that the cutting head can extend to the inside of the stainless steel elbow, and then uses the cutting head to perform flame cutting. However, the part of the pipe to be cut is not limited and fixed during cutting. As a result, when the pipe is about to be cut, the connection area between the main pipe and the part of the pipe to be cut is small and it is difficult to effectively support the part of the pipe to be cut. Therefore, it is easy to bend or even break in the connection area between the two, resulting in the incision of this pipe ring cutting device not being smooth enough and the cutting quality being poor. Therefore, the present invention provides a groove cutting and welding device for stainless steel elbow tee connection. Summary of the invention

[0004] The main purpose of the present application is to provide a groove cutting and welding device for stainless steel elbow tee connection, which can adapt to the inner diameter of the stainless steel elbow during the expansion process of the L-shaped sliding plate, and support the inner wall of the stainless steel elbow on both sides of the cutting line, so as to avoid the stainless steel elbow from deflecting and causing the remaining connection area to bend or even break, thereby preventing the incision from being smooth and having defects such as burrs, thereby improving the cutting quality of the stainless steel elbow incision.

[0005] To achieve the above-mentioned purpose, the present application provides a groove cutting and welding device for stainless steel elbow tee connection, comprising an elbow placement platform and a cutting and welding machine mechanism rotatably connected to one side of the elbow placement platform, wherein a bearing is sleeved on the outer side of the elbow placement platform, and a cutting and welding machine mechanism is connected to the outer side of the bearing through a connecting plate, and the cutting and welding machine mechanism comprises:

[0006] A base, fixedly connected to the other end of the connecting plate, and equipped with universal wheels at the four corners of the bottom of the base;

[0007] A vertical column is installed on the top of the base and can move back and forth along the length direction of the top of the base;

[0008] The cam is an angular movement of the cam which is engaged with the step of moving the two wheels together and the cam is engaged with the step of moving the two wheels together. The cam is an axisymmetric analysis tool which is used to measure the movement of the two wheels. The cam is an isometric analysis tool which is used to measure the movement of the two wheels. The cam is an isometric analysis tool which is used to measure the movement of the two wheels together.

[0009] Preferably, grooves are formed at equal intervals on the top of the elbow placement platform along its circumferential direction, and electric telescopic rods are installed inside the grooves, and the output ends of the electric telescopic rods are fixedly connected to limit blocks.

[0010] Preferably, an electric slide rail is installed at the edge positions of both sides of the top of the base, and a sliding seat that reciprocates through the electric slide rail is installed on the top of the base, and a vertical column is fixedly connected to the middle position of the top of the sliding seat.

[0011] Preferably, a slide rail is symmetrically fixed on one side of the vertical column, and a screw rod 1 is rotatably connected between the two slide rails, and a driving motor 1 for driving the screw rod 1 to rotate is installed at the top of the screw rod 1. A sliding plate that cooperates with the screw rod 1 and the slide rail is also installed on one side of the vertical column, and an electric slide rail 2 for driving the horizontal column to move horizontally is installed on the outer side of the sliding plate.

[0012] Preferably, an electric control box for controlling the electrical equipment inside the cutting and welding machine mechanism is installed on the vertical column.

[0013] Preferably, rollers are symmetrically mounted on the outer sides of the ends of the L-shaped sliding plate, and the output end of the nozzle is located in the middle position between the two rollers.

[0014] The benefits of the present application are as follows: first, the electric slide rail 2 drives the transverse column to extend to the inside of the tube wall of the stainless steel elbow, and then the driving motor 3 drives the bevel gear 1 to rotate, and synchronously drives the bevel gear 2 to rotate, thereby driving the screw rod 2 inside the tentacle of the octopus disc seat to rotate, so that the sliding block slides along the screw rod 2, and synchronously expands the L-shaped sliding plate outward, so that the octopus disc seat can correspond to the center point of the stainless steel elbow. During the expansion of the L-shaped sliding plate, the electric slide rail 1 drives the sliding seat and the vertical column to move, and at the same time, the driving motor 1 drives the screw rod 1 to rotate, so that the sliding plate moves along the slide rail and the screw rod 1, so that the transverse column can move up and down along the vertical column, so that the center point of the octopus disc seat can correspond to the center point of the stainless steel elbow through the process of moving the transverse column up and down and left and right, thereby achieving an adaptive effect. During the adaptive process, the base can move with the universal wheel, so that the facing direction of the octopus disc seat can be adaptively adjusted, thereby improving the cutting effect of the stainless steel elbow and improving the quality of cutting;

[0015] Secondly, after the L-shaped sliding plate is expanded, the roller is used to contact the inner wall of the stainless steel elbow, and then the stainless steel elbow is flame cut by the nozzle. Since the nozzle is located at the center position between the two rollers, during the flame cutting process of the stainless steel elbow by the nozzle, the two rollers on the same L-shaped sliding plate are used to support the stainless steel elbow on both sides of the cutting line respectively, so that the part to be cut off can be supported during cutting, avoiding the deflection of the stainless steel elbow and causing the remaining connection area to bend or even break, which will lead to uneven incisions and defects such as burrs, thereby improving the cutting quality of the incision of the stainless steel elbow.

[0038] In summary:

[0039] First, the stainless steel elbow is moved to the elbow placement platform 100 by a crane, and the electric telescopic rod 131 inside the groove 130 pushes the limit block 132 to move, so that the inside of one end of the stainless steel elbow is positioned by the limit block 132, so that the center point of one end of the stainless steel elbow corresponds to the center point of the top of the elbow placement platform 100, and then the stainless steel elbow is lowered by the crane, thereby completing the preparation work before cutting and welding of the stainless steel elbow;

[0040] Subsequently, since the cutting and welding machine mechanism is connected to the elbow placement platform 100 through the bearing 110 and the connecting plate 120, the cutting and welding machine mechanism is made to correspond to the end of the stainless steel elbow to be cut and welded by pushing the base 200, and then the horizontal column 400 is driven to extend to the inside of the pipe wall of the stainless steel elbow by the electric slide rail 2 306, and then the bevel gear 1 406 is driven to rotate by the driving motor 3 404, and the bevel gear 2 407 is driven to rotate synchronously, thereby driving the screw rod 2 410 inside the tentacles of the octopus disc seat 403 to rotate, so that the sliding block 411 slides along the screw rod 2 410, and synchronously expands the L-shaped sliding plate 405 outward, so that the octopus disc seat 403 can correspond to the center point of the stainless steel elbow. When the L-shaped sliding plate 405 expands During the process, the electric slide rail 220 drives the sliding seat 230 and the vertical column 300 to move, and at the same time drives the screw rod 302 to rotate through the driving motor 305, so that the sliding plate 303 moves along the slide rail 301 and the screw rod 302, so that the horizontal column 400 can move up and down along the vertical column 300, so that the center point of the octopus disc seat 403 can correspond to the center point of the stainless steel elbow by moving the horizontal column 400 up and down and left and right, so as to achieve an adaptive effect. In the adaptive process, the base 200 can move with the universal wheel 210, so that the facing direction of the octopus disc seat 403 can be adaptively adjusted, thereby improving the cutting effect of the stainless steel elbow and improving the quality of cutting;

[0041] At the same time, after the L-shaped sliding plate 405 is expanded, the roller 408 is used to contact the inner wall of the stainless steel elbow, and then the stainless steel elbow is flame cut by the nozzle 409. Since the nozzle 409 is located at the center position between the two rollers 408, during the process of flame cutting the stainless steel elbow by the nozzle 409, the two rollers 408 on the same L-shaped sliding plate 405 are used to support the stainless steel elbows on both sides of the cutting line, so that the part to be cut off can be supported during cutting, avoiding the stainless steel elbow from deflecting and causing the remaining connection area to bend or even break, which will lead to uneven incisions and defects such as burrs, thereby improving the cutting quality of the incision of the stainless steel elbow.
