Abstract
The utility model discloses a vertical steel bar electroslag welding machine, which is composed of a welding controller, a welding transformer and a welding head. The head is single column type and is fixed on the top and bottom steel bar by the concentric movable chuck and fixed chuck. The concentricity of the top and bottom steel bars is by a deviation-adjusting device for steel bar. An operation handle is arranged on the head body, and a welding flux bucket is arranged at the welding end of two steel bars. The welding controller makes the signal introduced into the supervisory instrument and prompts the finish time of slag forming, electroslag and welding. The utility model has the advantages of small size, light weight, steel product saving and electric energy saving, used for welding either the intensive steel bar or the diameter changing steel bar.
Description
The utility model relates to a kind of vertical reinforcement electroslag welder, belongs to welding technology field.
In architectural engineering, the welding quantity of vertical reinforcement is very big, particularly cast-in-place concrete engineering, and the welding quality that steel is connect also has strict demand.What the welding of old-fashioned vertical reinforcement was generally adopted is the overlap joint butt welding, though this method is simple, expends steel, and power consumption is big; New welding method is submerged-arc welding, there is the people once to invent the vertical reinforcement submerged arc welding machine thereupon, but this machine head heaviness, and adopt queen post and gear drive, be not suitable for construction of reinforcing bar dense part and job space, supporting with it welding equipment imperfection, work efficiency is low, and power consumption is big, and this technology is very unripe in addition, welding quality is not sure, and popularization is restricted.
The inventor has invented a kind of by being obtained 2000 ℃ of left and right sides high temperature molten slages by the arc-melting solder flux that forms between the welding steel muscle termination, to be melted equably by bonding tip, form the method for welding point again through extruding, this method has realized quick, high-quality electroslag welding to vertical reinforcement, facts have proved that this method is practical.
The purpose of this utility model provides a kind of vertical reinforcement electroslag welder that is applicable to above-mentioned welding method, and it is simple in structure, and is easy to operate, and consuming electric power is low, and is suitable for work high above the ground and the construction of reinforcing bar dense part.
The utility model is made of welding controller, welding transformer and welding head.The output of welding controller links to each other with welding transformer, two outputs of welding transformer join with fixing two concentric anchor clamps of reinforcing bar up and down respectively, anchor clamps and reinforcing bar conducting with one heart, one of two above-mentioned concentric anchor clamps are moving anchor clamps, can be up and down, another is fixed on the main body of welding head for to decide anchor clamps, welding termination at two velamen welding steel muscle is provided with the solder flux bucket, holds solder flux.
Welding process is controlled by welding controller, and with certain procedure control system indication welding degree, and welding controller links to each other with gauge tap with monitoring device on being arranged on welding head by cable.
Welding head also is provided with adjusts the reinforcing bar deviation correcting device of reinforcing bar concentricity up and down.
The moving anchor clamps of clamping reinforcing bar are by a lever, and end bar moves up and down to make it drive upward, and operating lever connects handgrip, and monitoring device and gauge tap are set on the handgrip, easily operation.
The reinforcing bar deviation correcting device is arranged on the lower body part of welding head, and decides anchor clamps and cooperates, and adjusts the reinforcing bar concentricity.
The solder flux bucket can be designed to cone-shaped, open-close type, and sealing also can be designed to other container shapes when closing.
The simplest method of reinforcing bar deviation correcting device is to adopt screw to regulate.
Accompanying drawing 1 is a structural representation of the present utility model.
Description of drawings:
1, solder flux bucket, 2, reinforcing bar, 3, handle, 4, operating lever, 5, monitoring device, 6, handgrip, 7, gauge tap, 8, moving anchor clamps, 9, main body, 10, felt pad, 11, decide anchor clamps, 12, the reinforcing bar deviation correcting device, 13, welding controller, 14, welding transformer.
The embodiment and the welding process that provide below in conjunction with accompanying drawing and accompanying drawing further describe the utility model.
Moving anchor clamps 8 one ends are fixed on the main body 9 by screw, the other end clamps reinforcing bar 2, it is concentric with moving anchor clamps 8 to decide anchor clamps 11, one end and main body 9 are fixing, reinforcing bar below the other end clamps, the concentricity of two reinforcing bars is regulated by the reinforcing bar deviation correcting device 12 that is arranged on main body 9 bottoms up and down, moving anchor clamps 8 link to each other with the operating lever 4 that is fixed on main body 9 tops, handgrip 6 is the plug formula, be installed on the operating lever 4, it is provided with monitoring device 5 and the gauge tap 7 that is connected with welding controller 13, is provided with open-close type solder flux bucket 1 at the welding ends of two reinforcing bars, and is fixed on the main body 9.
During welding, lay an iron wire ball, to help the starting the arc at the joint of two reinforcing bars, in solder flux bucket 1, pour into solder flux, connect power supply, press gauge tap 7, electric arc ignites, by the prompting of the voltage change on the control instrument 5 welding degree, electroslag begins voltage and is presented at about 40 volts, because high arc temperature, solder flux around the interface is fully melted, form slag bath, this process is controlled by welding controller 13, and is shown by monitoring device 5.Slag making finishes, voltage is presented at about 20 volts, after this lifts operating lever 4, through the lever transmission, drive moving anchor clamps 8 and top reinforcing bar, it is gently inserted in the slag bath, and arc extinction enters the electroslag process, electric current by slag bath strengthens, because slag bath has big resistance, and produces higher resistance heat, and the slag bath temperature is raise rapidly, steel bar end is melted equably, extruding is immediately squeezed deposite metal and slag and to be removed from the composition surface, send into monitoring device 5 through welding controller 13 and show signals, general this process needs to finish about 12 seconds, welding process finishes, and closing control switch 7 is cut off the electricity supply.
The utility model volume is little, and is in light weight, reliable operation, and maintenance and use are all very convenient, and welding head is an open side type, is specially adapted to the reinforcing bar dense part and vertically welds, and also is applicable to the welding that becomes the diameter reinforcing bar, saves steel and electric energy.
