Continuous type heat collection strip welding method without medium and its compacting device

Abstract

The present invention belongs to the field of no-medium welding technology. The technological process of no-medium welding continuous heat collecting strips includes the steps of regulation to straighten coil tube and align coil belt with the regulating mechanism; compacting the coil tube and the coil belt; argon arc welding or supersonic welding; and cutting to the required size in a cutting machine. The compacting device for no-medium welding continuous heat collecting strips consists of fixing frame and movable mechanism and has lower slot structure ad upper lead screw mechanism. The present invention has high production efficiency and product quality.

Description

technical field

[0001] The invention belongs to the field of medium-free welding technology, and in particular relates to a medium-free welding method for continuous heat-collecting strips and a pressing device thereof. Background technique

[0002] At present, there are two main forms of production of the existing all-copper solar collector strips: ultrasonic welding and argon arc welding. Ultrasonic welding is an indirect welding of fixed-length copper tubes and fixed-length copper strips, which is not continuous, and the specifications of the produced heat-collecting strips are limited. Argon arc welding is the welding of fixed-length copper tubes and variable-length copper strips. It is also an intermittent welding. The specifications of the heat-collecting strips produced are also limited, and the product rejection rate is high. Contents of the invention

[0003] In order to solve the problems in the prior art, the invention provides a continuous heat-collecting stri...

Examples

Embodiment 1

[0037] Refer to attached figure 1 and 2 . The continuous all-copper solar heat collecting strip medium-free welding method includes the following process:

[0038] 1) adjust

[0039] The copper coil tube is straightened by the straightening mechanism and then transported to the workbench, and the copper coil is conveyed to the workbench after being adjusted by the adjustment mechanism;

[0040] 2) Compression

[0041] On the workbench, use the pressing device to press the straightened copper pipe and the adjusted copper strip tightly;

[0042] 3) Welding

[0043] welding the compressed strips together with argon arc or ultrasonic welding;

[0044] 4) Cutting pieces

[0045] The cutting machine is used to blank and shape according to the required different sizes to obtain the finished product with the required specifications.

Embodiment 2

[0047] Refer to attached figure 1 and 2 . The continuous all-copper solar heat collection strip medium-free welding pressing device consists of a fixed frame and a movable mechanism. The lower part of the pressing device is an iron block 8 with a V-shaped groove. The iron block 8 is located on the workbench 4. The pressing device The upper part is a screw mechanism. The lead screw mechanism is assembled by a lead screw 1 with a handle 5 and a pressure head 2 and a fixed nut 6 . The welding pressing device can press the copper pipe 3 and the copper strip 7 tightly, so that argon arc welding or ultrasonic welding can be carried out well, so that the welding process can be continuously carried out, and the production efficiency and yield of products can be greatly improved.

Embodiment 3

[0049] Refer to attached figure 1 and 3 . The continuous all-copper solar heat collection strip medium-free welding pressing device is composed of a fixed frame and a movable mechanism. The lower part of the pressing device is an iron block 9 with a T-shaped slot, and the upper part is a screw mechanism. Lead screw structure is the same as embodiment 2.
