Abstract
The invention relates to a flash butt welding twisted steel butt joint device which is mainly used for steel bar butt joint in the field of constructional engineering. The flash butt welding twisted steel butt joint device has reliability in butt joint firmness, is simple in process and has low requirements for workers' skills. The flash butt welding twisted steel butt joint device is mainly composed of a connecting sleeve 1, a pair of fixed pliers 5 and a pair of movable pliers 6, a working table 8 and a flash butt welder. The main working principle of the flash butt welding twisted steel butt joint device is that first a clamp A5 is used to clamp a steel bar on the left side, a steel bar connector on the left side is inserted into a through hole 3 in the left side of the connecting sleeve 1, the left end of the connecting sleeve 1 abuts against the right end of the clamp A5, a steel bar on the right side is inserted into the through hole 3 in the right side of the connecting sleeve 1, a clamp B6 is used to clamp the steel bar on the right side, at the same time, the distance between the left end of the pair of movable pliers 6 and the right end of the connecting sleeve 1 is a value L, the flash butt welder is started, a low-voltage high current of the flash butt welder heats the steel bar connector into a plastic state, and then the pair of movable pliers 6 is pushed, so that the left end of the pair of movable pliers 6 abuts against the right end of the connecting sleeve 1 to finish steel bar butt joint.
Description
Technical field
Present invention is mainly used for building engineering field steel reinforcement abutting joints to use.
Background technology
The connected mode of commonly used flash butt welding, this connected mode is docked at present at building engineering field spiral
Strict to operation technological requirement, the operating technology of workman is required height, it is easy to produce lack of joint penetration, slag inclusion, weld metal
The mass defects such as burning, joint area crackle, these mass defects never allow for main steel bar stress, this steel
Muscle docking mode is the most gradually eliminated in China much areas.
Summary of the invention
Instant invention overcomes drawbacks described above, its docking is solid and reliable, and technique is simple, requires low to the technology of workman；This
Bright mainly it is made up of branch sleeve (1), fixation clamps (5), mobile pincers (6), workbench (8), flash butt welder；Branch sleeve (1)
There is enlarged cavity (2) centre, and both sides have through hole (3), the periphery of through hole (3) to have multiple air discharge duct (7)；Fixation clamps (5) and workbench
(8) fixing, fixation clamps (5) and mobile pincers (6) all have wire (9), wire (9) to be connected with the both positive and negative polarity of flash butt welder, fixing
Bar clamp can be handled by pincers (5) and mobile pincers (6)；The main operational principle of the present invention is: first by fixation clamps (5) by the left side
Bar clamp handles, then is inserted at the splice on the left side by the left side through hole (3) of branch sleeve (1) and make branch sleeve (1)
Left end withstands the right-hand member of fixation clamps (5), in then the reinforcing bar on the right inserts the through hole (3) on branch sleeve (1) the right and with moving
It is L-value that the bar clamp on the right is handled the distance of the left end simultaneously making mobile pincers (6) right-hand member away from branch sleeve (1) by dynamic pincers (6),
Starting flash butt welder, splice is heated to mecystasis by the low-voltage and high-current of flash butt welder, now heats reinforcing bar
Steam and flue gas that joint produces will be discharged from multiple air discharge ducts (7), then promote mobile pincers (6), make the left end top of mobile pincers (6)
Living the right-hand member of branch sleeve (1), steel reinforcement abutting joints completes；After reinforcing bar is heated to form plasticity, the thrusting action of mobile pincers (6), will mould
The splice pushing tow of sexual state to branch sleeve (1) enlarged cavity (2) in and be crowded with enlarged cavity (2), the splice on both sides
Forming enlarged footing in branch sleeve (1), the reinforcing bar deformed also is crowded with and is made the reinforcing bar on both sides connect by the through hole (3) on both sides simultaneously
Head position is connected sleeve (1) and clamps firmly, no matter at splice axially or radial direction, splice all without
Loosen；The volume assuming enlarged cavity (2) is V, and the radius of reinforcing bar is R, then reinforcing bar is pressed into length L=that enlarged cavity (2) shortens afterwards
V÷∏R2；Reinforcing bar by during action of pulling stress mainly by branch sleeve (1) stress, two splice faces can not be considered
Stressing conditions, accordingly even when there is mass defect and also do not interfere with the joint quality of whole banjo fixing butt jointing in two splice faces；
Need explanation: the left end of mobile pincers (6) is provided with rule；Branch sleeve (1) need to be according to different bar diameter customizations；Adapter sleeve
The medial surface of cylinder (1) scribbles fire-proof insulation paint.

Detailed description of the invention
Summary of the invention has been described in detail the detailed description of the invention of the present invention, is not repeated herein；Need explanation: see Fig. 3,
The enlarged cavity 2 of branch sleeve 1 refers to the cavity volume beyond through hole 3；The volume of the enlarged cavity 2 of the branch sleeve 1 of different-diameter
Being known, can calculate L-value required during the steel reinforcement abutting joints of different-diameter, L-value is exactly that the left end of mobile pincers 6 is away from connection
The distance of the right-hand member of sleeve 1, can be fabricated to label by the L-value needed for different bar diameter docking and installs in real work
On mobile pincers 6, compare label during operative it is known that L-value；By the medial surface brushing fire-proof insulation of branch sleeve 1
Paint is to make branch sleeve 1 remain in the event of high temperatures with charged splice keep insulation, makes the splice can be just
Often it is heated to mecystasis；Splice is simply heated to mecystasis by the present invention, therefore wants flash butt welding acc power
Ask low.
