Description
Technical field
The present invention relates to mechanical equipment technical field, the reduction thin-wall tube in a kind of laser cladding process is related particularly to
The device of shape part deformation.
Background technology
Laser melting coating is also known as laser cladding or laser melting coating, is a kind of new process for modifying surface.It passes through in base material table
Cladding material, and the method for being allowed to the consolidation together with substrate surface thin layer using the laser beam of high-energy-density are added in face, in base
The filling cladding layer that surface is formed with it is metallurgical binding.During laser melting coating thin-walled tubular part outer surface, part by
Heat will produce contraction distortion.
During existing laser melting coating thin-walled tubular part outer surface, first by reversible deformation tool in tubular member,
I.e. by applying precompression in advance into tubular member, can reduce in laser cladding process tubular member it is heated when generate
Contraction distortion.
Existing reversible deformation tool is in tubular member, by internal reversible deformation tool after tubular member deformation retract

Operation principle：Before thin-walled tubular part laser melting coating, regular polygon wedge block is symmetrically placed on borded pile
In first spiral and the second spiral, sector is mounted on soon between the symmetrical angle of regular polygon wedge block later, because symmetrical
The shape at angle match with fan-shaped fast shape, so fan-shaped can be stuck in soon on the symmetrical angle of regular polygon wedge block, pacify
After the completion of dress, the device of the application is put into thin-walled tubular part, the both ends of borded pile are respectively in the outer of thin-walled tubular part
Side after laser melting coating, rotates borded pile, because the first spiral and second hand of spiral on the contrary, therefore when borded pile rotation, two can be made
Regular polygon wedge block is moved to borded pile both ends respectively simultaneously in opposite directions, and two pieces of regular polygon wedge blocks move from thin
After wall tubular member, each sector is loosened because not having support element soon, and it is adjacent it is fan-shaped it is fast between be arranged and have the gap, so each
Sector directly drops in thin-walled tubular part soon, convenient to be taken out out of thin-walled tubular part.By borded pile, the first spiral,
Second spiral, two regular polygon wedge blocks and fan-shaped fast setting, device will not be stuck in inner wall because of outer wall contraction, tear open
Unload, be easy for installation, solve it is above-mentioned after tubular member deformation retract by the very tight of internal reversible deformation tool holder, reversible deformation work
Tool is difficult to remove, and dismantles difficult defect.
Further, each fast scalloped surface of sector is provided with briquetting with matching, the sector soon with
It is detachably connected between the briquetting.By replacing different-thickness briquetting, can be applied in the part for becoming internal diameter.
Further, described to be detachably connected as spiral connection or pin connection.Installation is simple, easy to disassemble.
Further, the thickness of the briquetting is 120-1000mm.By replacing different-thickness briquetting, can be applied to
Become in the part of internal diameter.
Further, the thickness of the briquetting is 200mm.The briquetting applying frequency higher of the thickness.
Further, the regular polygon wedge block is equilateral triangle, square, regular hexagon, regular pentagon or positive seven
Side shape.So that briquetting and the contact of tubular member inner wall are more abundant.
Further, the regular polygon wedge block is equilateral triangle.Easy to process simple, stability is high, borded pile
It is laborsaving when rotation.
Further, the end of at least one end of the borded pile is regular polygon column cap.Facilitate clamping and by borded pile
Rotation.
Further, each regular polygon column cap is triangle, square, regular pentagon or regular hexagon.Side
Just it is clamped and rotates borded pile.
Further, each regular polygon wedge block is sequentially reduced from outer end face to inner face.When dismounting, make two
Regular polygon wedge block is more effortless when being moved respectively to borded pile both ends simultaneously in opposite directions, and the exterior power needed is less.
Beneficial effects of the present invention are as follows：(1) pass through borded pile, the first spiral, the second spiral, two regular polygon wedge shapes
Block and fan-shaped fast setting, device will not be stuck in inner wall because of outer wall contraction, dismantle, is easy for installation；(2) by replacing not
Stack pile briquetting can be applied in the part for becoming internal diameter；(3) setting of regular polygon wedge block so that briquetting and tubulose zero
The contact of part inner wall is more abundant；(4) device is easy to process simple, and stability is high.
