Description
Technical field
The utility model relates to reinforcing bar electric resistance welding technology field, particularly relates to a kind of reinforcing bar flash welding machine.
Background technology
Resistance welding applies pressure by electrode after being combined by workpiece exactly, and the resistance heat utilizing the contact surface of electric current by joint and adjacent domain to produce carries out the method welded. Electric resistance welding method mainly contains four kinds, i.e. spot welding, seam weldering, projection welding and butt welding, but when common resistance welding technology welds, power consumption is very big, it is desired to welder power is big, and waste of material, cost height.
The utility model improves to overcome the above problems.
Practical novel content
The purpose of this utility model is to provide a kind of productivity height, and power consumption is low, and cost is low and high efficiency reinforcing bar flash welding machine.
The utility model is the technical scheme that its technical problem of solution adopts,
A kind of reinforcing bar flash welding machine, comprise frame, transformer it is provided with below frame, it is provided with electrode between described frame and transformer, described electrode is connected and fixed clamp and adjustable cramp respectively, stationary clamp and adjustable cramp is in the same plane and has the gap that can install workpiece between the two, under described stationary clamp, end is provided with fixed base plate, fixed base plate and stationary clamp connect as one, under described adjustable cramp, end is provided with movable base plate, movable base plate and adjustable cramp connect as one, described fixed base plate and the horizontal periphery of movable base plate are provided with two guide rails, seat board is close to by guide rail, in described movable base plate side, one pressing mechanism is installed, pressing mechanism drives movable base plate to pressurize along guide rail to fixed base plate side and moves.
Further, described stationary clamp and adjustable cramp are provided with folder hole, fixing for clamping of welding work pieces.
Further, described pressing mechanism adopts pinned connection, reliable operation, convenient disassembly.
The utility model has the advantage of:
1. flash of light process has exhausted air, reduces the self-protection function of burning.
2. flash of light process has stronger inherent regulation function, keeps the requirement of consistent property lower to strict, welding quality stable.
3. unit welded section is long-pending needs electric power little.
4. welding productivity height, welds a joint and only needs several seconds to tens seconds.
5. welding applied widely, the metallic substance that can forge in principle can weld with flash welding.
6. the long-pending scope of welded section is big, generally can weld from tens to several ten thousand mm2 sectional areas.
7. flash welding is widely used in welding various plate, pipe fitting, section bar, solid member, cutter etc., and application is very extensive, is a kind of economy, high efficiency welding process.

Embodiment
In order to the utility model is realized technique means, creation characteristic, reach object and effect is easy to understand, below in conjunction with diagram and specific embodiment, set forth the utility model further.
With reference to shown in Fig. 1 and Fig. 2, a kind of reinforcing bar flash welding machine that the utility model proposes, comprise frame 1, transformer 2 it is provided with below frame 1, it is provided with electrode 3 between described frame 1 and transformer 2, described electrode 3 is connected and fixed clamp 6 and adjustable cramp 8 respectively, stationary clamp 6 and adjustable cramp 8 are in the same plane and have the gap that can install workpiece 7 between the two, described stationary clamp 6 times ends are provided with fixed base plate 5, fixed base plate 5 and stationary clamp 6 connect as one, described adjustable cramp 8 times ends are provided with movable base plate 9, movable base plate 9 and adjustable cramp 8 connect as one, described fixed base plate 5 and the horizontal periphery of movable base plate 9 are provided with two guide rails 4, seat board is close to by guide rail 4, in described movable base plate 9 side, one pressing mechanism 10 is installed, pressing mechanism 10 drives movable base plate 9 to pressurize along guide rail 4 to fixed base plate 5 side and moves.
Further, described stationary clamp 6 and adjustable cramp 8 are provided with folder hole, fixing for clamping of welding work pieces 7.
Further, described pressing mechanism 10 adopts pinned connection, reliable operation, convenient disassembly.
The utility model principle of work: flash welding divides two stages, and the first stage is flash stage, subordinate phase is the top forging stage.
1. flash stage
In this stage, first switch on power, and make two workpiece 7 end face gentle touchdown, form many point of contact. When electric current passes through, point of contact melts, and becomes the liquid metal lintel connecting both ends of the surface. Owing to the current density in liquid lintel is extremely high, make that the liquid metal in lintel evaporates, lintel explosion. Along with the slow propelling of adjustable cramp 6, lintel also constantly produces and explosion. Under the effect of vapor pressure and electromagnetic force, liquid metal particulate constantly ejects between interface, forms spark torrent--flash of light.
2. push up the forging stage
At the end of flash stage, workpiece 7 applying enough top pressure immediately, interface gaps reduces rapidly lintel and stops explosion, namely enters the top forging stage. The burner stayed after pushing up the gap and liquid metal lintel explosion that the effect forged is sealing workpiece 7 end face, extrude liquid metal and the oxide inclusion of end face simultaneously, clean plastic metal is in close contact, and make joint 71 district produce certain viscous deformation, to promote the carrying out of recrystallize, form common crystal grain, to obtain firmly joint 71. Though there being deposite metal during flash welding in heat-processed, but it it is substantially plastic state welding.
More than show and describe ultimate principle of the present utility model, main characteristic sum advantage of the present utility model. The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model. The claimed scope of the utility model by appending claims and etc. jljl define.
