Problems solved by technology

[0002] Some TV brackets will use spherical cast steel to make a door-shaped structure, but some existing methods will cut the whole piece of cast steel, and at the same time combined with the size requirements, a whole piece of cast steel can only be cut into one The bracket causes waste of the remaining material. At the same time, the cutting cost is high, and the finished product quantity and efficiency are low.
At the same time, direct three-stage welding is also used, but the surface of the welded product is rough and uneven, which does not meet customer requirements at all, the welding efficiency is low, and the welding technology requirements for operators are relatively high.

Embodiment 1

[0025] Clamp the workpiece to be welded, and first apply force to the workpiece to be welded through the impact force of 150kg, so that the part to be welded is in contact. When the temperature is 1200 ° C, according to the formula F = P / V, select the P of the first hot melt as 75KW, the speed is 0.5mm / s, and the melting time is 3S. At this temperature, according to the formula F = W / S, push the product to be welded forward 8mm, perform the second melting and welding, and select W as 1200J , the second hot-melt welding lasts for 4S, and the time interval between the first hot-melt and the second hot-melt welding is 0.1s, and the finished product can be further processed by grinding the surface of the weld, In order to make the surface of the welding place smooth and smooth.

Embodiment 2

[0027] Clamp the workpiece to be welded, firstly apply force to the workpiece to be welded through the impact force of 150kg, so that the part to be welded is in contact, when the temperature is 1400°C, according to the formula F = P / V, select the P of the first hot melt as 80KW, the speed is 0.5mm / s, and the melting time is 3S. At this temperature, according to the formula F = W / S, advance the product to be welded 9mm forward for the second melting and welding, and choose W as 1600J , the second hot-melt welding lasts for 3S, and the time interval between the first hot-melt and the second hot-melt welding is 0.1s, and the finished product can be further processed by grinding the surface of the weld, In order to make the surface of the welding place smooth and smooth.

Embodiment 3

[0029] Clamp the workpiece to be welded, first apply force to the workpiece to be welded through the impact force of 150kg, so that the part to be welded is in contact, when the temperature is 1500°C, according to the formula F = P / V, select the P of the first hot melt as 85KW, the speed is 0.5mm / s, and the melting time is 2S. At this temperature, according to the formula F = W / S, push the product to be welded forward 10mm, perform the second melting and welding, and select W as 2000J , the second hot-melt welding lasts for 3S, and the time interval between the first hot-melt and the second hot-melt welding is 0.1s, and the finished product can be further processed by grinding the surface of the weld, In order to make the surface of the welding place smooth and smooth.

Abstract

The invention discloses a hot-melting welding technology for a television bracket. The television bracket is door-shaped. The technology comprises the following steps: S1, placing a bracket to be welded on a welding tool; S2, applying the impact force of 150 kg to workpieces to be welded to enable the parts to be welded to be in contact; S3, for the workpieces in contact, selecting power P and velocity V according to the formula: F=P / V, controlling the temperature to be 1200-1500 DEG C, and controlling the hot-melting time to be 2-3 S; S4, for the products subjected to the hot-melting in the S2, selecting power W and movement distance S according to the formula namely F=W / S to push the products forwards for welding, controlling the temperature to be 1200-1500 DEG C, and controlling the welding time to be 3-4 S; S5, performing grinding processing on welded part of welded products through a grinding machine. The technology has the advantages that the overall process is quick and fast; the shaped product is attractive in appearance; the efficiency is improved; besides, as the welding is carried out by using the materials of the product to be welded, the strength of the product welded is 1.5 times above of that of the product welded by using the conventional materials.
