Abstract
The invention discloses a closing plate for welding, which comprises a metal plate. The closing plate for welding is characterized in that a closing plug which is formed by means of stretching processing is arranged in the middle of the metal plate, and a ring used for being lapped with an orifice is formed at the edge of the metal plate. The closing plug with certain strength is formed on the closing plate by means of stretching processing, the depth of the closing plug ranges from 0.5cm to 1.2cm, the closing plug is plugged into a pipe to be in close fit with the wall of the pipe when the closing plate is used, and can be automatically positioned without spot welding, the ring at the edge of the closing plate can be directly welded, a weld joint is positioned at the top end of the pipe and does not affect the diameter of the pipe, and firmness of the weld joint is improved.
Description
Technical field
The present invention relates to welding technology field, particularly a kind of closure plate that is used for the heating pipe sleeve pipe of absorption and diffusion type refrigerating box generator.
Background technique
As everyone knows, the generator of absorption and diffusion type refrigerating box comprises interior pipe, outer tube and heating pipe sleeve pipe, and the heating pipe sleeve pipe pastes with interior pipe mutually, in the heating pipe sleeve pipe, places internally liquid heat in the pipe of heater, makes the generator can proper functioning.
Usually the closed end of heating pipe sleeve pipe is to weld a circular small iron plate in the weldless tube cannula tip of 12*1.2, and an end of heating pipe sleeve pipe is closed, and prevents that liquid from flowing into sleeve pipe; This small iron plate just can carry out welding processing, otherwise can't fix after must fixing through some heel pipe; Inefficiency and be difficult for centering; Be easy to weldering partially, weld joint postwelding on outer diameter side has increased pipe diameter, influences the assembling of heating pipe sleeve pipe and generator outer tube.
Summary of the invention
The present invention has overcome the deficiency that exists in the above-mentioned existing technology, and shape, the structure of iron plate in the above-mentioned existing technology have been done improvement, and a kind of closure plate that is used to weld welding, that improved working efficiency that is easy to assemble is provided.
Technological scheme of the present invention is achieved in that
A kind of closure plate that is used to weld comprises a tinsel, and described tinsel middle part is provided with the closing cock that drawn is processed to form, and the edge of tinsel is formed for the annulus with mouth of pipe overlap joint.
As preferably, the degree of depth of said closing cock is 0.5～1.2cm.Can guarantee to seal and be plugged with enough degree of depth and fill in the mouth of pipe.
Adopted the invention has the beneficial effects as follows of technique scheme:
The present invention is with the closing cock that is formed with certain intensity after the stretched processing of closure plate; The degree of depth of closing cock is 0.5～1.2cm; Closing cock is filled in the pipe and the tube wall close-fitting during use; Do not need spot welding just can locate voluntarily, the annulus at closure plate edge directly can weld and the weld joint does not influence the diameter of managing on the top of pipe, has increased the fastness of weld seam simultaneously.
Description of drawings
Fig. 1 is the structural representation of closure plate of the present invention;
Fig. 2 is the linkage structure schematic representation of heating pipe sleeve pipe and closure plate among the embodiment.
Embodiment
Embodiment of the present invention is following:
Embodiment: a kind of closure plate that is used to weld, as shown in Figure 1, comprise a tinsel 4, described tinsel 4 middle parts are provided with the closing cock 3 that drawn is processed to form, and the edge of tinsel 4 is formed for the annulus 2 with mouth of pipe overlap joint.
Application example of the present invention is following: for example a kind of heating pipe sleeve pipe; In use need an end be sealed; As shown in Figure 2, this heating pipe sleeve pipe comprises sleeve body 1, is provided with tinsel 4 in the bottom of sleeve body 1; The closing cock 3 of tinsel 4 is connected with sleeve body 1 tube wall close-fitting, and the annulus 2 that tinsel 4 edges form overlaps with sleeve body 1 mouth of pipe and welds together.
Closure plate of the present invention can be used for the mouth of pipe welding in a plurality of fields.
Claims (2)
