Description

Technical Field

[0001] The utility model relates to the technical field of external half-pipe welding of kettles, in particular to a stainless steel external half-pipe stacking welding device for kettles. Background Technique

[0002] The external half-pipe reactor uses a series of half-pipes as a heat exchange jacket. The half-pipe can be a circular half-pipe or a square half-pipe. The bottom head and the cylinder can both be provided with half-pipes. The heat exchange area can be large or small and can be set as needed. Since the external half-pipe reactor is spiraled in a series of circles, it is evenly heated, has a good flow guiding effect, and will not overheat locally. A heat preservation layer is provided outside the external half-pipe reactor, and the appearance is beautiful and generous, and there are no cleaning dead corners.

[0003] In the prior art, before welding the external half-pipe, generally, the reactor is placed on rollers, rotated, and then the external half-pipe is welded manually. This not only has a low processing efficiency but also increases the production cost.

[0004] Therefore, we propose a stainless steel external half-pipe stacking welding device to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stainless steel external half-pipe stacking welding device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A stainless steel external half-pipe stacking welding device, including two brackets, a welding device is arranged between the two brackets, and the welding device includes a welding part;

[0007] The welding part includes a double-headed motor, a return frame, a limiting part, a slider, a mounting plate and a welding pen. The mounting plate is threadedly sleeved on the outer surface of the welding pen. The bottom surface of the return frame is fixedly connected to the top surface of the bracket. The left end surface of the double-headed motor is fixedly connected to the right end surface of the return frame. The outer surface of the top end of the limiting part slidably penetrates through the bottom surface of the slider and extends above the slider;

[0009] The positioning part further includes a C-shaped plate, a screw rod and a synchronous pulley. A groove is provided on the inner wall of the positioning part bracket. The outer surface of the C-shaped plate extends into the groove and is fixedly connected to the inner wall of the groove. The outer surface of the right end of the screw rod rotatably penetrates through the inner wall of the C-shaped plate through a first bearing and extends to the right side of the C-shaped plate. The two synchronous pulleys are respectively fixedly sleeved on the outer surface of the right output shaft of the double-headed motor and the outer surface of the screw rod, and the outer surfaces of the two synchronous pulleys are connected by a synchronous belt.

[0010] A further improvement lies in that the outer surface of the left output shaft of the double-headed motor rotates through the right end face of the loop-shaped frame by means of a second bearing and extends into the interior of the loop-shaped frame. The slider is threadedly sleeved on the outer surface of the left output shaft of the double-headed motor. By providing the double-headed motor, the slider, the mounting plate and the welding pen, starting the double-headed motor causes the welding pen to move left and right, facilitating the welding of the outer semi-circle to the outer surface of the stainless steel kettle.

[0011] A further improvement lies in that the welding part further includes a spring and a second rotating shaft. The bottom surface of the second rotating shaft is fixedly connected to the top surface of the slider.

The bottom surface of the positioning rod is fixedly connected to the top surface of the upper splicing block. By providing the positioning rod, the screw rod, the upper splicing block and the lower splicing block, the outer semi-circle before welding is limited by the positioning rod. At the same time, by adjusting the distance between the positioning rod and the welding pen, outer semi-circle pipes with different spacings can be produced.
