BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a welding composite apparatus for manufacturing high precision built-up materials used in the manufacture of ships or steel structures, and more particularly, to the welding line of built-up materials. The present invention relates to a welding complex apparatus for fabricating a high-precision built-up material which enables a continuous production by including all processes necessary for fabrication.

Generally, the built-up material is manufactured by integrally welding a web material that is orthogonally positioned with respect to a horizontally located flange, and an example of a conventional manufacturing method thereof is illustrated in FIG. 3. 3 (a) to 3 (d) show a manufacturing process diagram of the built-up material produced by the conventional welding method.

As shown in FIG. 3 (a), the reference ratio is primarily orthogonal to the flange 2 and the web member 3, and then the tack welding is performed at regular intervals at the joints thereof. It is common to move the welded built-up material 1 to this welding apparatus, and to weld again the site welded by the welding torch 4a, 4b primarily.

However, the welding productivity is low due to the occurrence of blow holes and poor bead welding defects at the tack welding point P. In particular, as shown in FIG. However, due to the residual heat of welding, it cannot be sent directly to the calibration process, which is a later process, but moves to the STOCK AREA of the calibration atmosphere. The element is occurring. In addition, since the correction work for correcting the welding deformation depends on the hydraulic system and the mechanical press 5 as shown in FIG. 3 (d), it requires a considerable technical skill, and the built-in correction is repeated several times depending on the deformation amount. -It is a bottleneck in the industrial production process (BOTTLE NECK), which is a factor that reduces productivity. In addition, due to the inconsistent working speed between the welding and the calibration process, it is a fact that it is a deterioration factor of continuous flow production.

Accordingly, an object of the present invention is to solve the above-mentioned shortcomings and to construct a facility necessary for the production of the built-up material as a welding device, so that a high accuracy built-up material can be obtained without undergoing post-weld correction of the built-up material. The present invention provides a built-in welding composite device.

A feature of the present invention for achieving the above object is, in the welding device to be welded to the joint portion of the built-up material of at least two welded material, it is possible to load the welded object forming the built-up material in a moving state. And a rotating means rotatably installed for transferring the loaded built-up material to the welding means, the fixed-up material being fixedly installed on the moving path of the built-up material in the conveying means and conveyed along the conveying means. A welding means for welding the joint portion, the welding means being disposed at a position adjacent to the built-up material at a spaced apart position from the welding means, and adapted to apply the same amount of heat to both sides of the built-up material as the heat generated during welding by the welding means; Heating means, and cooling water for injecting cooling water into the built-up movement path of the built-up material at a position spaced apart from the heating means and moving with the welding heat. A welding complex apparatus for manufacturing a high precision built-up material including the injection means.

Below. Based on the accompanying drawings, a more preferred embodiment of a welding composite apparatus for manufacturing a high precision built-up material according to the present invention will be described in detail.

FIG. 1 is a side view schematically showing a welding complex apparatus for manufacturing a high precision built-up material according to the present invention from one side, and FIG. 2 is a view shown in the arrow A direction of FIG. The same parts as in the past are denoted by the same reference numerals in order to avoid redundant description.

As shown in the drawing, the apparatus according to the present invention is provided with two spaced apart first and second conveying conveyors 10a and 10b. The first conveying conveyor (10a) is used to load the flange (2), the web member (3), which is the welded object constituting the built-up material (1) in a moving state, the second conveying conveyor (10b) is built-in It is provided to make the up-material 1 be conveyed toward the welding torch mentioned later. The rotational speeds of the first and second conveying conveyors 10a and 10b can be arbitrarily adjusted.

In addition, the pair of first and second guide rollers 14a, 14b (15a, 15b) and the third guide roller 16 are provided in the first and second conveyance conveyors 10a and 10b. Each is provided. The pair of first guide rollers 14a, 14b support both sides of the flange 2 of the built-up material 1 conveyed along the first and second conveying conveyors 10a, 10b, while The pair of second guide rollers 15a and 15b support both sides of the web member 3. The third guide roller 16 firmly supports the upper end of the web member 3.

Therefore, when the built-up material 1 is transported by the first and second transport conveyors 10a and 10b, the built-up material 1 is safely transported without being transferred to either side. In particular, the third guide roller 16 is in a state in which the web member 3 is pressed against the flange 2, thereby suppressing the occurrence of a gap Gap between the flange 2 and the web member 3.

Hydraulic cylinder 20 which can be moved up and down with respect to one end of the said 1st conveying conveyor 10a, ie, the one end of the built-up material 1, with respect to the edge part of the built-up material 1; Is integrally mounted. In addition, a lattice fitting member 24 is integrally attached to the upper end of the piston 22 of the hydraulic cylinder 20. The fitting member 24 is provided for fitting the ends of the flange 2 and the web material 3 to coincide with each other. A pair of welding torches 30 are fixedly installed at an upper portion of the second conveying conveyor 10b at a position adjacent to the built-up material 1 conveyed along the second conveying conveyor 10b. -The joint part of the flange 2 and the web material 3 which comprise the up-material 1 is welded. In addition, a pair of heaters 40a and 40b are provided at both sides of the path of the built-up material 1 directly above the welding torch 30, that is, the web material 3. On the discharge side of the built-up material 1, which is one end of the second conveying conveyor 10b, a pair of sludge removers 50 are installed to remove sludge generated during welding by the welding torch 30. In the vicinity of the sludge remover 50, a coolant sprayer 60 is mounted to spray coolant toward the bottom of the built-up material 1. The coolant sprayer 60 is used to cool the heated built-up material 1 during welding.

An example of the operation of the welding complex apparatus according to the present invention configured as described above will be described in detail with reference to FIGS. 1 and 2.

The flange 2 and the web material 3 constituting the built-up material 1 are sequentially loaded on the first conveying conveyor 10a. That is, when the dust flange 2 is placed on the first conveying conveyor 10a and the web material 3 is placed thereon and pushed, these welded objects are transferred to the first conveying conveyor 10a and the guide rollers 14a and 14b. Easily loaded by the rolling operation of (15a, 15b).

When the built-up material 1 is formed by the loading of the flange 2 and the web material 3, the piston 22 is lifted up at the same time as the hydraulic cylinder 20 at the end of the first conveying conveyor 10 a. It works. The lattice-fitting member 24 in the raised piston 22 encounters the end of the built-up material 1 which is loaded and moved on the first conveying conveyor 10a, so that the flange 2 and the web material 3 You can easily match the end of

When the end-fitting operation of the built-up material 1 is completed, the raised cylinder 20 is returned to its original position. Since the shangdong operation of the cylinder 20 is an extremely general technique, a detailed description thereof will be omitted. Only one-point P of the end of the built-up material 1 is called TACK WELDING. The built-up material 1 of which the tack welding is completed is conveyed toward the 2nd conveyance conveyor 10b located adjacently.

When the built-up material 1 is conveyed onto the second conveying conveyor 10b, the first and second guide rollers 14a, 14b, 15a and 15b which are located on the second conveying conveyor 10b and The third guide roller 16 accurately guides the built-up material 1 conveyed from the first conveying conveyor 10a and causes the welding torch 30 to weld the point P1 of the built-up material 1. Make sure that it is set correctly so that this welding can be performed. This operation is performed by the sensor 70 installed in the inlet of the built-up material 1 of the second conveyance conveyor 10b. That is, the sensor 70 detects the moment when the built-up material 1 enters the second conveyance conveyor 10b, and the detection signal is transmitted to the welding torch 30 and the like as described above. The operation is executed. On the contrary, when the built-up material 1 leaves the sensor 70, the operation by the welding torch 30 or the like is stopped, and the transfer of the built-up material 1 is waited for. The operation of the sensor 70 can be modified in various ways, and thus only one of the specific embodiments will be omitted.

Heat is applied from the heaters 40a and 40b. The heaters 40a and 40b are used for the purpose of preventing deformation of the weld shrinkage by the heat of welding as the built-up material 1 is shown in FIG. That is, the heaters 40a and 40b apply the same amount of heat to the web material 3 of the built-up material 1 as the amount of heat generated during the welding by the welding torch 30. As shown in FIG. 2, the built-up material 1 is not deformed when only welding heat is applied. Although the heat amount of the heaters 40a and 40b is preferably equal to the amount of heat generated during welding, the temperature of the heaters 40a and 40b may be arbitrarily adjusted as necessary.

The built-up material 1 to which heat is applied to prevent deformation while welding is immediately passed through the coolant sprayer 60 located at the rear end, and the coolant sprayer 60 sprays the coolant onto the built-up material 1 by The heat is removed and sent directly to the post process. In addition, the sludge generated at the welding point p1 at the time of welding is removed by the sludge remover 50 operated simultaneously with the welding.
