Problems solved by technology

[0003] In the existing welding technology, the needle-shaped oxide and phosphide slag in the weld will make the weld metal brittle and reduce the mechanical properties. Iron oxide and iron sulfide slag can easily make the weld brittle, and the slag will affect the The performance of the pipeline is greatly affected, because most of the slag inclusions are irregular, so it will reduce the solidity and toughness of the weld

Embodiment 1

[0036] A device suitable for welding metal round pipes that can reduce surface welds, such as Figure 1-5 As shown, it includes a slotted floor frame 1, a driving mechanism 2 and a welding mechanism 3. The slotted floor frame 1 is provided with a driving mechanism 2, and the welding mechanism 3 for welding metal round pipes is also arranged on the slotted floor frame. 1 on.

[0037] The driving mechanism 2 includes a motor support frame 21 and a bidirectional motor 22 , the motor support frame 21 is fixedly mounted on the slotted floor frame 1 , and the bidirectional motor 22 is fixedly mounted on the motor support frame 21 .

[0038] Welding mechanism 3 includes special-shaped grooved frame 31, sliding bushing 32, countersunk rotating shaft 33, pinion 34, first return spring 35, belt pulley 36, rubber belt 37, H type grooved frame 38, sheave 39, middle Gear 310, sliding electrode cover 311, second back-moving spring 312, electrode body 313, the third back-moving spring 314 a...

Embodiment 2

[0041] On the basis of Example 1, such as Figure 4-5 As shown, a welding slag scraper 4 is also included, and the welding slag scraper 4 is used to scrape off the welding slag at the welding place, and the welding slag scraper 4 is welded on the connecting frame 315 .

[0042] It also includes a preheating cylinder 5, which is symmetrically welded on the sliding electrode cover 311, and is used for heating the ports of the two metal circular tubes.

[0043] The left and right reciprocating motion of the connecting frame 315 can drive the reciprocating movement of the welding slag scraper 4, and the welding slag scraper 4 scrapes off the welding slag at the welding place, so that the welding place of the two metal pipes is smooth without protrusions. The preheating cylinder 5 can heat the ends of the two metal circular tubes, making it easier for the electrode body 313 to weld them together.

Embodiment 3

[0045] On the basis of Example 2, such as Figure 6-14 As shown, it also includes a slow-speed rotation mechanism 6, and the slotted floor frame 1 is connected with a slow-speed rotation mechanism 6 in a symmetrical sliding manner. 63, Y-shaped sliding frame 64, the fourth back-moving spring 65, Q-shaped support frame 66 and large gear 67, two ends of bidirectional motor 22 output shafts are welded with octahedral shaft body 61, on the octahedral shaft body 61 slidingly connected with eight The face shaft sleeve 62 and the eight-side shaft sleeve 62 are fixedly connected with missing gears 63, and the slotted floor frame 1 is connected with a Y-shaped sliding frame 64 in a symmetrical sliding manner, and the Y-shaped sliding frame 64 is rotationally connected with the eight-face shaft sleeve 62, The Y-shaped sliding frame 64 is fixedly connected with a fourth return spring 65, one end of the fourth return spring 65 away from the Y-shaped sliding frame 64 is connected with the ...

Abstract

The invention relates to the field of metal pipe processing, in particular to a device suitable for welding metal round pipes that can reduce surface weld seams, including a slotted floor frame, a driving mechanism, a welding mechanism, etc.; the slotted floor frame is provided with a driving mechanism, The welding mechanism is also arranged on the slotted floor frame. The special-shaped push rod will push the sliding bushing and the parts connected to it to move towards the direction of the H-shaped slotted frame, instead of manually pushing the sliding bushing, and the rotation of the clamping block will drive the two metal round tubes to rotate slowly, instead of manual rotation. The two metal round pipes are fully welded together.

Description

technical field [0001] The invention relates to the field of metal pipe processing, in particular to a device suitable for welding metal round pipes that can reduce surface weld seams. Background technique [0002] With the continuous development of metal connection history, welding technology has been continuously improved in industrial production, and the development of welding technology is changing with each passing day. Welding technology is a manufacturing process and technology for joining metals by heating, high temperature or high pressure. The slag in the weld is called slag inclusion. [0003] In the existing welding technology, the needle-shaped oxide and phosphide slag in the weld will make the weld metal brittle and reduce the mechanical properties. Iron oxide and iron sulfide slag can easily make the weld brittle, and the slag will affect the The performance of the pipeline is greatly affected, because most of the slag inclusions are irregular, so it will red...
