Description
Technical field
This utility model relates to machinery manufacturing technology field, especially relates to the soldering frock of a kind of tube sheetbrace angle joint.
Background technology
Chemical machinery manufacturing, heat exchanger is the most common equipment, and in equipment Manufacture Process, having at one is tube sheet
The welding of angle joint, normal welding has a weak point: often can be in welding process, because heat exchanger tube extension elongation only has
1.5～2.5mm, it is easy to when manual welding and tube sheet automatic welding, because equipment or operator are unstable, cause heat exchanger tube
Tube head produce weldering gap, the most unsightly, the intensity of butt welded seam also has a certain degree of slackening.
Utility model content
For above-mentioned technical problem, this utility model purpose is to provide the soldering frock of a kind of tube sheetbrace angle joint, to strengthen
The intensity of weld seam, improves its outward appearance.
The technical solution adopted in the utility model is:
The soldering frock of a kind of tube sheetbrace angle joint, including Copper alloy bar and clamping part, the diameter of described Copper alloy bar is slightly smaller
In the internal diameter of the heat exchanger tube of heat exchanger, the inside of the termination of described heat exchanger tube is inserted in one end of described Copper alloy bar, and described copper closes
The other end of gold rod is placed in the outside of the termination of described heat exchanger tube, and the other end of described Copper alloy bar is provided with clamping part.
The soldering frock of tube sheetbrace angle joint described in the utility model, wherein, described Copper alloy bar is red copper bar or pyrite
Rod.
The soldering frock of tube sheetbrace angle joint described in the utility model, wherein, described clamping part is cylinder.
The soldering frock of tube sheetbrace angle joint described in the utility model, wherein, a diameter of 5-10mm of described cylinder.
The soldering frock of tube sheetbrace angle joint described in the utility model, wherein, a length of 20-of described Copper alloy bar
50mm。
This utility model beneficial effect:
The soldering frock of tube sheetbrace angle joint described in the utility model, the material of heat exchanger tube is stainless steel pipe and high quality carbon
Steel tubing, they will not produce fusion phenomenon with this frock, and butt welding raw heat energy of practicing midwifery plays again the effect of quickly cooling, separately
Outward, also act as the effect of welding backing, form smooth inner surface in the inner side of tube wall identical with the inwall of heat exchanger tube, the most not
The most attractive in appearance, and, the weldering meat of projection will not be formed at heat exchanger tube inwall, hinder the quality affecting tube expansion that penetrates of tube expander, receive
Arrive preferable effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the soldering frock of tube sheetbrace angle joint described in the utility model.
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
Detailed description of the invention
As it is shown in figure 1, the soldering frock of a kind of tube sheetbrace angle joint, including Copper alloy bar 1 and clamping part 2, Copper alloy bar 1 is
Red copper bar or brass bar, according to the internal diameter size of heat exchanger tube 3, the diameter of Copper alloy bar 1 is slightly smaller than the interior of the heat exchanger tube 3 of heat exchanger
Footpath, the internal diameter of heat exchanger tube 3 is 15-34mm, and the inside of the termination of heat exchanger tube 3 is inserted in one end of Copper alloy bar 1, Copper alloy bar 1
The other end is placed in the outside of the termination of heat exchanger tube 1, and the other end of Copper alloy bar 1 is provided with clamping part 2, and one end of clamping part 2 leads to
Crossing to be welded and fixed and be arranged in Copper alloy bar 1, clamp when being used for picking and placeing, clamping part 2 is cylinder, a diameter of 5mm of described cylinder,
The a length of 30mm of Copper alloy bar 1.
The soldering frock of tube sheetbrace angle joint described in the utility model, in use, first closes the copper processed
Gold rod 1 is placed with in the heat exchanger tube 3 of gap, stays 10mm outside heat exchanger tube 1, uses common argon arc welding method to weld heat exchanger tube
Described gap between 3 terminations and tube sheet 4 forms weld seam 5；After welding terminates, take out Copper alloy bar 1 by clamping part 2, again
Put into other heat exchanger tube 3 needing soldering, repeat above action, can the quantity of the heat exchanger tube 3 of soldering as required, multi-processing
Several Copper alloy bar 1, use in turn, also allow for scattering and disappearing of heat.
Owing to the material of general heat exchanger tube 3 is stainless steel pipe and quality carbon steel tubing, they will not with this frock
Producing fusion phenomenon, the raw heat energy of practicing midwifery of butt welding simultaneously plays again the effect of quickly cooling, it addition, also act as the work of welding backing
With, form smooth inner surface in the inner side of heat exchange tube wall identical with the former inwall of heat exchanger tube 3, the most attractive in appearance, and welded pipe
During the follow-up heat exchanger tube expanded joint of plate angle joint, will not form the weldering meat of projection at heat exchanger tube 3 inwall, that hinders tube expander penetrates shadow
Ring the quality of tube expansion, have received preferable effect, be worthy to be popularized.
Embodiment described above is only to be described preferred implementation of the present utility model, not to this practicality
Novel scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various deformation that the technical scheme of utility model is made and improvement, all should fall into the protection that this utility model claims determine
In the range of.
