Description

TV bracket sweat soldering technique
Technical field
The present invention relates to a kind of TV bracket sweat soldering technique.
Background technology
Portal structures can be made using spherical cast steel in some TV brackets, but existing certain methods can be complete by monoblock Cast steel cut, and in combination with size requirements, a monoblock cast steel can only be cut into a support, cause clout portion The waste divided, meanwhile, this cutting cost is high, and output and efficiency are low.Meanwhile also have using direct three-sectional welding, but weld The product being connected into is uneven in weld rough surface, does not meet customer requirement completely, welding efficiency is low, the weldering for operative employee Connection technology requires higher.
The content of the invention
It is an object of the present invention to provide a kind of high TV bracket sweat soldering technique of welding efficiency.
The technical scheme is that：
TV bracket sweat soldering technique, the TV bracket is in shaped door, comprises the following steps,
S1, clamping step, branch to be welded is placed on welding tooling；
S2, pre- heat fusion step, the impulsive force for first passing through 150kg are treated welding workpiece and exerted a force, and enter part to be welded Row contact；
S3, heat fusion step, the workpiece after contact choose power P and speed V according to formula F=P/V, and control temperature exists Between 1200 DEG C -1500 DEG C, hot molten time 2-3S；
S4, welding step, the product after the hot melt in S2 is chosen into work(W and move distance according to formula F=W/S S, so as to carry out propulsion welding, control temperature is between 1200 DEG C -1500 DEG C, weld interval 3-4S；
S5, grinding step, the product for welding completion are carried out by milling drum the grinding of welding portion.
Preferably, in the S3 heat fusion steps, the power P is 75-85KW, and speed V is 0.5mm/s.
Preferably, the work(W described in the S4 welding steps is 1200-2000J, and move distance S is 8-10mm.
Preferably, the S2 heat fusion steps and the S3 welding steps interval time are 0.1S.
Preferably, the S2 heat fusion steps are consistent with temperature in the S3 welding steps.
It is an advantage of the invention that：Whole process is quick, convenient, and the product appearance after shaping is attractive in appearance, and efficiency improves, and this Invention is welded using bulk material, and the intensity after welding is more than 1.5 times of raw material welding.
Specific implementation
Present invention is disclosed a kind of TV bracket sweat soldering technique, the TV bracket is in shaped door, the support By a straight trip section and the L-shaped section at straight trip section both ends is welded in, the junction of the straight trip section and L-shaped section has a fusible socket part, The weld portion is generally 8-12mm, specifically needs with reference to required TV bracket length.The sweat soldering work of the present invention Skill comprises the following steps,
S1, clamping step, branch to be welded is placed on welding tooling；
S2, pre- heat fusion step, the impulsive force for first passing through 150kg are treated welding workpiece and exerted a force, and enter part to be welded Row contact；
S3, heat fusion step, the workpiece after contact choose power P and speed V according to formula F=P/V, and control temperature exists Between 1200 DEG C -1500 DEG C, hot molten time 2-3S；The S2 heat fusion steps are with the S3 welding steps interval time 0.1S.The power P is 75-85KW, and speed V is 0.5mm/s.The S3 welding steps are protected with temperature in the S2 heat fusion steps Hold consistent.
S4, welding step, the product after the hot melt in S2 is chosen into work(W and move distance according to formula F=W/S S, so as to carry out propulsion welding, control temperature is between 1200 DEG C -1500 DEG C, weld interval 3-4S；Described work(W is 1200-2000J, move distance S are 8-10mm.
S5, grinding step, the product for welding completion are carried out by milling drum the grinding of welding portion.
Due to the control of meeting limited location between heat fusion step and welding step, the S2 heat fusion steps walk with S3 hot melts Rapid interval time is 0.1S.After the completion of welding, because face of weld can have solder-bump, finally further by be ground into Row surface treatment, to reach the support of necessary requirement.
