At this time, one end of the Thomson knife perpendicular to both side ends is brought into close contact with the second gripping groove 222a of the second jig member 222 of the second jig 220, and the cylinder device of the jig moving device 300 The first gripping grooves 212a of the first jig member 212 of the first jig 210 are brought into close contact with the other end portions of the Thomson knife so that the first jig 210 and the first jig member 210 2 jig 220, as shown in Fig.

At this time, the object to be welded 10 may be positioned above or inside the spacing space 140 between the first stand 120 and the second stand 130. That is, if the welding object 10 is accommodated between the first jig 210 and the second jig 220 at a height between the first upper plate 122 and the second upper plate 132, And if the size of the object to be welded 10 is long or large in the height direction of the first stand 120 and the second stand 130, it may be located inside the spacing space 140 .

In this state, the welded portions, that is, the portions where both end portions of the Thomson knife are butt against each other, are welded using the welded portion 500. To this end, first, the end of the torch 510 of the welding part 500 is positioned so as to face the welding part. In this process, the position adjusting screw 820 of the second horizontal moving device 800 is rotated to move the second cylinder mounting table 810, thereby moving the lifting device 600 and the torch 510, The end of the welded portion 510 is positioned above the welded portion.

The normal lifting device 600 may be maintained in an elevated state so that the torch 510 can be maintained remotely located above the first jig 210 and the second jig 220, When welding is desired, the lifting device 600 can lower the torch 510 to a position at which the torch 510 can weld the welding site of the Thomson knife.

When the torch 510 is positioned at a distance where the welding portion of the Thomson knife can be welded, the view protection mechanism 530 is lowered toward the front of the torch 510 and the driving switch 1010 of the control unit 1000 is lowered. The valve 922 of the gas supply unit 900 is opened so that the welding gas is supplied from the gas supply unit 900 to the torch 510 to weld the welding spot of the Thomson knife by the torch 510.

When the welding portion of the Thomson knife is welded through the torch 510, the torch 510 is moved in the direction in which the first jig 210 and the second jig 220 face each other through the first horizontal moving device 700 Can be moved along. For this purpose, the operator grasps the handle 724 of the first horizontal movement device 700 and rotates the handle 724 clockwise or counterclockwise in one direction so that as the screw 723 rotates, the screw 723 Is moved along the axial direction of the screw 723 to move the torch 510 from the position of the first jig 210 to the position of the second jig 220 or to the position of the second jig 220 when the moving plate 721b, The welding portion of the Thompson knife can be spot-welded while moving from the position of the first jig 210 to the position of the first jig 210.

The automatic welding apparatus according to one embodiment of the present invention has the following advantages.

First, since the spacing space 140 is formed at a position where the welding object 10 is fixed, the welding object 10 having various sizes can be fixed. Accordingly, the size of the object to be welded 10 is not limited The welding object 10 can be easily fixed and the welding operation can be performed.

Secondly, the elevating and lowering device 600 for raising and lowering the welded part 500 is mounted on the second stand 130, that is, on the second upper plate 132 of the second stand 130, The structure of the elevating and lowering apparatus 600 for raising and lowering the welded portion 500 can be simplified and the space for installing the elevating and lowering apparatus 600 can be easily secured have.

Thirdly, while the position of the torch 510 is moved in the direction perpendicular to the direction in which the first jig 210 and the second jig 220 are opposed to each other through the second horizontal movement device 800, The first jig 210 and the second jig 220 move along the direction in which the torch 510 faces the first jig 210 and the second jig 220 through the first horizontal moving device 700, The entire region can be spot-welded, so that a simple and quick welding can be achieved.

Hereinafter, an automatic welding apparatus according to another embodiment of the present invention will be described in detail with reference to FIG. 6, focusing on differences from an automatic welding apparatus according to an embodiment of the present invention. 4 is a front view for explaining an automatic welding apparatus for a neck-and-neck knife welding according to another embodiment of the present invention.

4, an automatic welding apparatus for welding a neck-and-neck knife according to another embodiment of the present invention includes an automatic welding apparatus according to an embodiment of the present invention, except that it further includes a welding object receiving unit 1100, The welding object receiving portion 1100 will be mainly described below.

The welding object receiving unit 1100 is configured such that when the welding with the welding unit 500 is completed with respect to the object to be welded 10 and then the fixing is released through the first and second jigs 210 and 220, As shown in FIG. For example, the welding object receiving portion 1100 may include a second cylinder device 1110 and a welding object support 1120.

The second cylinder device 1110 may be fixed on the base plate 110 of the table 100 and be located in the spacing space 140. The second cylinder device 1110 may include a cylinder rod 1111, and the cylinder rod 1111 may be moved up and down.

The welding object support 1120 may be connected to the upper end of the cylinder rod 1111 of the second cylinder device 1110. The welding object support 1120 may have a rectangular plate shape. The size of the rectangular plate may have a length corresponding to the length of the spacing space 140 and a width corresponding to the width of the spacing space 140, for example.

In the automatic welding apparatus for welding a wooden mold knife according to another embodiment of the present invention, when the object to be welded 10 is fixed to the first and second jigs 210 and 220, When the object to be welded 10 is released from the first jig 210 and the second jig 220 after the welding operation is completed after being raised by the cylinder device 1110 and located close to the bottom of the object 10 The welding object 10 is placed on the upper surface of the welding object support 1120.

When the first jig 210 and the second jig 220 release the fixing of the welding object 10, the operator manually presses the welding object 10 in order to prevent the welding object 10 from falling down The operator is able to easily remove the welding object 10 having been welded on the welding object support 1120. [

On the other hand, a sound-absorbing layer may be applied to the bottom surfaces of the first upper plate 122 and the second upper plate 132.

The nonwoven fabric constituting the sound-absorbing layer may be a needle punch nonwoven fabric.

The types of the fibers constituting the sound-absorbing layer made of the needle punch nonwoven fabric include polyester fibers, nylon fibers, polypropylene fibers, acrylic fibers, and natural fibers.

The thickness of the sound-absorbing layer is preferably 0.3 to 15 mm. If the thickness of the sound-absorbing layer is less than 0.3 mm, a sufficient sound-absorbing effect can not be obtained. If the thickness is more than 15 mm, the inner space of the first upper plate 122 and the second upper plate 132 is reduced, Which is a disadvantage.

The unit weight of the sound-absorbing layer is preferably 10 to 1000 g / m 2 . If it is less than 10 g / m 2 , a sufficient sound absorption effect can not be obtained, and if it exceeds 1000 g / m 2 , the light weight of the first upper plate 122 and the second upper plate 132 can not be secured.

The fineness of the fibers constituting the sound-absorbing layer is preferably in the range of 0.1 to 30 decitex. If it is less than 0.1 decitex, absorption of low-frequency noise is difficult and cushioning property is lowered, which is not preferable. Further, if it exceeds 30 decitex, it is not preferable to absorb high frequency noise. Among these, the fineness of the fibers constituting the sound-absorbing layer is more preferably in the range of 0.1 to 15 decitex.

Since the sound-absorbing layer is provided on the bottom surfaces of the first upper plate 122 and the second upper plate 132, the noise transmitted to the first upper plate 122 and the second upper plate 132 during the welding operation can be reduced.

In addition, the first jig 210 and the second jig 220 may be made of FCD cast iron.

This FCD cast iron is heated to 1600 to 1650 ° C to be molten, then subjected to a desulfurization treatment, to a spheroidizing treatment agent containing about 0.3 to 0.7% by weight of magnesium, to a spheroidizing treatment at 1500 to 1550 ° C, and then to heat treatment.

Since FCD cast iron is a cast iron in which graphite is spherically crystallized during the solidification process by adding magnesium or the like to the molten metal of general gray cast iron, the shape of graphite is spherical compared to gray cast iron. Since such FCD cast iron has less notch effect, stress concentration phenomenon is reduced, and strength and toughness are greatly improved.

The first jig 210 and the second jig 220 of the present invention are formed by heating an FCD cast iron to 1600 to 1650 캜 to make a molten metal and then subjecting it to a desulfurization treatment and adding a spheroidizing treatment agent containing about 0.3 to 0.7% Followed by spheroidizing treatment at 1500 to 1550 ° C, followed by heat treatment.

Here, if the FCD cast iron is heated to less than 1600 DEG C, the entire structure can not be sufficiently melted, and if it is heated above 1650 DEG C, unnecessary energy is wasted. Therefore, it is preferable to heat the FCD cast iron to 1600 to 1650 캜.

If the amount of magnesium is less than 0.3% by weight, the effect of injecting the spheroidizing agent is negligible. If the amount of magnesium is more than 0.7% by weight, the effect of injecting spheroidizing agent There is a problem that an expensive material cost is increased while not greatly improving. Therefore, the mixing ratio of magnesium in the spheroidizing agent is preferably about 0.3 to 0.7% by weight.

When the spheroidizing treatment agent is injected into the molten FCD cast iron, it is subjected to spheroidizing treatment at 1500~1550 ° C. If the spheroidizing treatment temperature is lower than 1500 ° C., the spheroidizing treatment is not properly performed. If the spheroidizing treatment temperature is higher than 1550 ° C., the spheroidizing treatment effect is not greatly improved, but unnecessary energy is wasted. Therefore, the spheroidization treatment temperature is preferably 1500 to 1550 ° C.

Since the first jig 210 and the second jig 220 of the present invention are made of FCD cast iron, the stress concentration phenomenon is reduced because the notch effect is small, and the strength and toughness are greatly improved.

The first gripping groove 212a and the second gripping groove 222a can be coated with a reinforcing coating layer.

The reinforcing coating layer is composed of a mixture of 96 to 98% by weight of chromium oxide (Cr 2 O 3 ) and 2 to 4% by weight of titanium dioxide (TiO 2 ) in the first gripping groove 212 a and the second gripping groove 222a, and has a thickness of 50 to 600 mu m, and is coated with plasma to maintain the hardness of 900 to 1000 HV.

The reason why ceramic is applied to the outer peripheral surfaces of the first gripping grooves 212a and the second gripping grooves 222a is to prevent abrasion and corrosion. Compared to chrome plating or nickel chrome plating, the ceramic coating has excellent corrosion resistance, scratch resistance, abrasion resistance, impact resistance and durability.

Chromium oxide (Cr 2 O 3 ) acts as a passivity layer to block oxygen entering the inside of the metal, thereby preventing rusting.

Titanium dioxide (TiO 2 ) is a white pigment because it is very stable physicochemically and has high hiding power. And is also widely used for ceramics having high refractive index because of high refractive index. And has characteristics of photocatalytic property and superhydrophilic property. Titanium dioxide (TiO 2 ) acts as an air purification function, an antibacterial function, a harmful substance decomposition function, a pollution prevention function, and a discoloration prevention function. This titanium dioxide (TiO 2 ) ensures that the reinforcing coating layer is coated on the outer circumferential surfaces of the first gripping grooves 212a and the second gripping grooves 222a, and dissolves and removes foreign matter adhering to the reinforcing coating layer Thereby preventing the coating layer from being damaged.

Here, chromium oxide (Cr 2 O 3) and when using hayeoseo mixing titanium dioxide (TiO 2), the mixing ratio of these, chrome oxide (Cr 2 O 3) Titanium dioxide (TiO 2) in 96-98% by weight 2 By weight to 4% by weight.

When the mixing ratio of chromium oxide (Cr 2 O 3 ) is less than 96 to 98%, the coating of chromium oxide (Cr 2 O 3 ) is often broken in an environment of high temperature or the like, The rust preventive effect of the second gripping groove 212a and the second gripping groove 222a was reduced suddenly.

When the mixing ratio of titanium dioxide (TiO 2 ) is less than 2 to 4 wt%, the effect of titanium dioxide (TiO 2 ) is insignificant so that the purpose of mixing it with chromium oxide (Cr 2 O 3 ) is discolored. In other words, titanium dioxide (TiO 2 ) decomposes and removes foreign matter adhered to the periphery of the first gripping groove 212a and the second gripping groove 222a to form a first gripping groove 212a and a second gripping groove 222a ) Is prevented from being corroded or damaged. When the mixing ratio is less than 2 to 4% by weight, there is a problem that it takes much time to decompose the attached foreign matter.

The hardened coating layer made of such materials has a thickness of 50 to 600 mu m around the first gripping groove 212a and the second gripping groove 222a and has a hardness of 900 to 1000 HV and a surface roughness of 0.1 to 0.3 Lt; RTI ID = 0.0 > m. ≪ / RTI >

The reinforcing coating layer is sprayed by spraying the above powdered powder and gas at 1400 캜 around the first gripping groove 212a and the second gripping groove 222a at a Mach 2 speed to 50 to 600 탆 .

If the thickness of the reinforcing coating layer is less than 50 탆, the effect of the above-mentioned ceramic coating layer can not be guaranteed. If the thickness of the reinforcing coating layer exceeds 600 탆, the above-mentioned effect is insignificant, There is a problem that the working time and material cost are wasted.

The temperature of the outer circumferential surface of the cutting blade 12 is increased while the reinforcing application layer is applied to the first and second gripping grooves 212a and 222a. The heated first gripping grooves 212a and the second gripping grooves 222a, The first gripping grooves 212a and the second gripping grooves 222a are cooled by the cooling device (not shown) so that the temperature of the first gripping grooves 212a and the second gripping grooves 222a is maintained at 150 to 200 ° C.

A sealing material made of anhydrous chromic acid (CrO 3 ) made of a metal-based glass quartz system may further be applied to the periphery of the reinforcing coating layer. Anhydrous chromic acid is applied as an inorganic sealing material around the coating layer made of chromium nickel powder.

Anhydrous chromic acid (CrO 3 ) is used in places that require high abrasion resistance, lubricity, heat resistance, corrosion resistance and releasability, is not discolored in the atmosphere, has high durability, and has good abrasion resistance and corrosion resistance. The coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m. If the coating thickness of the sealing material is less than 0.3 mu m, the sealing material easily peels off even in a slight scratch groove, and the above-mentioned effect can not be obtained. When the coating thickness of the sealing material is made thick enough to exceed 0.5 mu m, pin holes, cracks, and the like are increased on the plated surface. Therefore, the coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m.

The coating layer having excellent wear resistance and oxidation resistance is formed around the first gripping groove 212a and the second gripping groove 222a so that the first gripping groove 212a and the second gripping groove 222a are worn or oxidized And thus the life of the product is prolonged.
