The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention. It should be noted that the words "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings.

As shown in FIG. 1, an energy-saving welding system is mainly used for welding the side surfaces of two steel plates; the welding device comprises a welding device 1 and two clamps 2 which are oppositely arranged left and right.

Each clamp 2 comprises two clamping blocks 21 which are oppositely arranged up and down; the two clamping blocks 21 are connected in a relatively movable manner by a screw 22, and the distance between the two clamping blocks 21 can be adjusted by rotating the screw 22. The inner side surface of each clamping block 21 is provided with a phase change material block 23; each phase-change material block 23 is a metal block packaged with a solid-liquid phase-change material; wherein the phase change material is preferably octadecanol.

Each clamp 2 can move along the horizontal longitudinal direction (the left and right directions in the attached figure 1 are the longitudinal directions, and the same is applied below); the concrete structure is as follows: the bottom of each clamp 2 is provided with a base 24, and the base 24 is arranged on a longitudinal dovetail sliding groove table 25; the longitudinal sliding of the base 24 causes the movement of the clamp 2 in the longitudinal direction.

The welding device 1 is arranged at the outer side of the two clamps 2 (the middle of the two clamps is defined as the inner side, and the other side of the opposite inner side of the clamps is defined as the outer side), and comprises a support table 11, a welding machine 12 and a welding rod chuck 13; the welding machine 12 is arranged on the support platform 11, and the welding rod chuck 13 is arranged above the space between the two clamps 2 and is fixed on the support platform 11 through a bracket 14; the supporting platform 11 is arranged on the air cylinder 15, and specifically, the bottom of the supporting platform 11 is connected with the top of an air cylinder arm of the air cylinder 15; meanwhile, the air cylinder 15 is arranged on the sliding cart 16, and the sliding cart 16 is slidably arranged on a transverse (transverse direction is perpendicular to the paper surface of the attached drawing 1, the same below) slide rail 17; specifically, the bottom of the sliding trolley 16 is provided with a sliding chute, the bottom of the sliding chute is provided with a wheel, and a transverse sliding rail 17 is just embedded in the sliding chute and is abutted against the wheel; under the drive of conventional equipment such as a servo motor, the sliding vehicle 16 slides on the transverse sliding rail 17; with the above structure, the movement of the welding wire holder 13 in the vertical direction and the horizontal lateral direction is realized.

The operation principle of the system is as follows: when a first pair of steel plates are welded, each clamp 2 clamps a preheated steel plate by adjusting the distance between the clamping blocks 21, and meanwhile, the phase change material blocks 23 are abutted to the surfaces of the steel plates; two steel plates to be welded are abutted together from the side by the movement of the clamp 2 along the horizontal longitudinal direction; the welding rod is abutted to a welding seam to be welded through the movement of the welding rod clamping head 13 along the vertical direction; then, the whole welding line is horizontally and transversely moved and welded through a welding rod clamping head 13; a large amount of heat is generated during welding, so that the local temperature is increased; at this time, the solid-liquid phase change material in the phase change material block 23 abutting against the steel plate can generate phase change from solid to liquid, and simultaneously absorb a large amount of heat, so that the local overheating phenomenon can not occur; after the steel plates are welded, the next two steel plates are respectively clamped by the clamp 2 and kept for a plurality of minutes (the time can be flexibly set according to the size of the steel plates and the temperature during welding); at the moment, the phase-change material block 23 is attached to a new steel plate, and due to the fact that the temperature of the new steel plate is low, the phase-change material is subjected to phase change again, and is solidified from a liquid state to a solid state, and meanwhile, the stored heat is released, so that the new steel plate is preheated, and after the new steel plate is preheated to a certain degree, welding is started; the circulation is carried out, and no additional preheating step is needed in the following steel plate welding, so that the working procedures are reduced, and the workload is reduced.

It should be noted that the system can be used for other types of welding, such as welding of box beams, welding of steel pipes, etc., by means of suitable adaptation, such as adjustment of the position and shape of the two clamps 2.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
