Abstract
The invention discloses a strain clamp crimping device and a crimping process. The strain clamp crimping device comprises two die bodies and round metal tubes, wherein the two die bodies can move in the opposite directions, and the round metal tubes can be located in the two die bodies. The two die bodies can form a hexagonal inner cavity after being combined. Plastic protecting sleeves are arranged outside the round metal tubes in a sleeving mode. After the two die bodies are combined, the plastic protecting sleeves extrude the outer surfaces of the round metal tubes to form a corner structure. After the structure and the process are adopted, burr trimming is completely eliminated, in the corresponding process, two traditional key working procedures are omitted, ten minutes is saved, and the time for crimping one strain crimping tube is shortened to be 20 minutes from 30 minutes in the past; polishing damage to the surface of an aluminum tube is reduced, the surface of the aluminum tube keeps natural and smooth, and corona loss is reduced; no trimming burrs are generated on a crimped strain clamp, and therefore the overall attractiveness of the strain clamp is improved; generation of waste such as iron powder and aluminum powder is avoided, soil pollution is avoided, wire corona is reduced, and the crimping device saves energy and is environmentally friendly.
Description
Technical field
The present invention relates to a kind of hydraulic connecting of aerial cable construction strain clamp, specifically a kind of strain clamp compression bonding apparatus and compression joint technique.
Background technology
Strain clamp in aerial cable construction needs to carry out crimping process to the circular metal tube-surface of wire clamp usually, but has certain plasticity due to round metal tube, under the extruding of the higher punching block of hardness, deforms obvious; Directly contact in addition between round metal tube and punching block, during crimping, traditional mould is adopted to carry out crimping process, during punching block move toward one another, the resistance that four tangent planes contacted with round metal tube pipe produce, the frictional force acted on round metal tube makes the material of circular metal tube-surface create displacement, and the metal material in A, B, C, D tetra-regions is piled up to opening direction extruding, thereby produce burr phenomenon, adopt traditional compression joint technique simultaneously, need to check the rear opposite side distance size of pressure after the first mold pressing is good; Then exert pressure to one end, adjacent two moulds at least answer overlapping 5mm; Rear deburring all pressed by steel pipe, passed examination; Continue to aim at pressing mold limit at steel pipe marking place and press the first mould, then, towards aluminum pipe mouth direction side pressure second mould, from the second mould, adjacent two moulds at least answer overlapping 5mm, after having crimped, carry out crimping dimensional gaughing, file deflashing burr, carries out alignment to there being bending aluminium hydraulic pressed connecting pipe in code allowed band, aluminum pipe is rotated along aluminium stock strand direction processed and pushes steel anchor side to, till overlapping with steel anchor marking A at the bottom of aluminum pipe, as can be seen here, there is following defect in traditional this technique:
1, the traditional handicraft used time is longer; The master operation flow process of strain clamp conventional crimping techniques and the used time statistics of each operation, in master operation, there are two critical processes, (rear deburring all pressed by steel pipe, passed examination) and (after crimping completes, carry out crimping dimensional gaughing, file deflashing burr), these two operations respectively account for 5 minutes, account for 1/3 of total used time;
2, traditional handicraft has increased the weight of the corona loss of strain clamp; In operation, grinding process is carried out to strain clamp surface, to the aftertreatment on strain clamp surface, make the surface of strain clamp more easily corona occur;
3, the strain clamp of traditional handicraft crimping has burr, affects attractive in appearance.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and saves man-hour, low, the specious strain clamp compression bonding apparatus of loss and compression joint technique.
In order to solve the problems of the technologies described above; strain clamp compression bonding apparatus of the present invention; comprise can move toward one another two die bodys and two die body round metal tubes can be positioned at; a hexagonal inner chamber can be formed after two die bodys are involutory; round metal tube overcoat has plastic protective sleeve, by plastic protective sleeve, circular metal tube outer surface is extruded and form corner structure after two die bodys are involutory.
Described round metal tube is steel pipe or aluminum pipe.
Described die body is punching block.
A kind of compression joint technique of strain clamp, comprise preparation, stripping aluminium stock, wear steel pipe, compressed steel pipe, wear aluminum pipe, jewelling plumber sequence, in compressed steel pipe step, first, arrange the plastic protective sleeve of steel pipe, carry out pressing mold with above-mentioned strain clamp compression bonding apparatus, secondly, first mold pressing well checks the rear opposite side distance size of pressure afterwards, and then carry out to one end the second mould of exerting pressure, adjacent two moulds at least answer overlapping 5mm; In jewelling pipe step; first; arrange the plastic protective sleeve of aluminum pipe; aim at pressing mold limit at the steel pipe marking place pressed with above-mentioned strain clamp compression bonding apparatus and press the first mould, then towards aluminum pipe mouth direction side pressure second mould, from the second mould; adjacent two moulds at least answer overlapping 5mm; to there being bending aluminium hydraulic pressed connecting pipe to carry out alignment, aluminum pipe being rotated along aluminium stock strand direction processed and pushes steel anchor side to, till overlapping with the steel anchor marking at the bottom of aluminum pipe.
After adopting above-mentioned Structure and energy, because the matched moulds inner chamber arranged is that hexagonal two die bodys and round metal tube overcoat have plastic protective sleeve, before crimping steel pipe, aluminum pipe, with plastic protective sleeve, pipe fitting is protected respectively, during hydraulic pressure crimping, related plastic protective sleeve crimps together, frictional force is reduced by the plastic protective sleeve arranged, completely eliminate burr phenomenon, in the technique of its correspondence, eliminate tradition two critical processes, save 10 minutes, make the time originally crimping a strain insulator aluminium hydraulic pressed connecting pipe reduce to 20 minutes from 30 minutes; The polishing reducing aluminum tube surfaces destroys, and aluminum tube surfaces keeps nature smooth, reduces corona loss; Strain clamp after crimping does not produce burr, improves the overall appearance degree of strain clamp; Iron powder and aluminium powder the like waste can not be produced, do not produce soil pollution, reduce the energy-conservation environmental protection again of conductor corona.
