Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seam clad processing apparatus for a plate material, and particularly intends to enable the quick and easy coating of a corrosion-resistant thin metal plate on a plate material by utilizing a seam welding method.

[0002]

[Prior Art]

 Conventionally, a clad plate material for the purpose of improving corrosion resistance has been manufactured by using an explosion clad method or a rolling roll in which a corrosion-resistant metal thin plate such as a titanium plate placed on an SS steel plate is explosion-bonded as a clad plate as a base plate material. A roll processing method in which a pressure is applied by applying a pressure was applied.

[0003]

[Problems to be solved by the device]

 However, in the production of the clad plate according to the above-mentioned technique, in each case, there is a problem that a large amount of equipment is required and the risk of processing is very high. Moreover, in the production of high-grade clad plates with excellent corrosion resistance, it was difficult to secure stable quality, and the manufacturing cost was inevitably increased. It is an object of the present invention to propose a seam-clad processing device for plate materials that can be processed quickly and easily without any danger in the clad plate manufacturing process.

[0004]

[Means for Solving the Problems]

 The invention is an apparatus for producing a clad plate having a corrosion-resistant metal thin plate coating on at least one side of a mother plate material made of steel or non-ferrous metal, in which the mother plate material and the corrosion-resistant metal sheet are superposed and locally bonded. A mounting table that sandwiches and temporarily holds the temporary fixing material formed from both sides, and the temporary fixing material that is fixedly held on this mounting table is sandwiched from both sides to form a welded portion between the mother plate and the thin plate. And a welding machine having a pair of seam welding electrode rolls, wherein the above-mentioned mounting table comprises an upper table that can move with the temporary fixing material fixed and a lower table that supports the upper table, and at least the electrode roll and the mounting table. One is a seam clad machining apparatus for a plate material, which has a movable mechanism movable in a direction orthogonal to the rotation axis of the electrode roll and along the rotation axis.

1 (a) and 1 (b) show the structure of a processing apparatus according to the present invention. Reference numeral 1 in FIG. 1 is locally formed by spot welding or the like by superimposing a base plate 1a and a corrosion-resistant thin metal plate 1b. 2 is a mounting table on which the temporary fixing member 1 is mounted and is fixedly held by sandwiching the temporary fixing member 1 from both side surfaces thereof with the vices 2a. The mounting table 2 includes the upper table 2b and the lower table 2c. It becomes a split type, and the lower table 2c can move forward and backward along the rail 1 (X direction) together with the upper table 2b holding the temporary fixing material 1 fixed, and the upper table 2b fixes the temporary fixing material 1 independently from the lower table 2c. It is possible to move back and forth in the direction (Y direction) orthogonal to it while holding it. A welding machine 3 is a pair of seam welding electrodes which sandwich a temporary fixing material 1 fixedly held on a mounting table 2 from both side surfaces thereof to form a welded portion between the mother plate 1a and the thin plate 1b. The rolls 3a and 3b are provided. Further, 4 is an elevator for moving the welding machine 3 up and down (Z direction) with the electrode rolls 3a, 3b. This elevator 4 has a drive shaft 4a and an elevator drive unit 4b for rotationally driving this drive shaft and an elevator 4 A control device 4c is provided for outputting a command for moving up and down and welding operation.

[0006]

[Action]

 In order to perform the seam clad welding of the temporary fixing material 1 with the apparatus having the above-mentioned configuration, first, the temporary fixing material 1 spot-welded as shown in FIGS. 2 (a) to (c) is placed on the mounting table 2 The upper vise 2a is clamped and fixed, and sandwiched between the electrode rolls 3a and 3b from both side surfaces thereof. Here, the electrode rolls 3a, 3b are preliminarily arranged by a driving means such as a hydraulic cylinder so as to reduce the distance between the electrode rolls. However, the upper base 2b and the lower base 2c are separately operated by Y. Since it can move back and forth in the direction, even if the temporary fixing member 1 is not located at the intermediate position between the electrode rolls 3a and 3b, it can be appropriately pressed by pressing one of the electrode rolls 3a and 3b. It is conveniently placed in position. Then, a continuous or intermittent reciprocating motion along the rail 1 is applied to the mounting table 2 and the elevating drive unit 4b is driven to raise the electrode rolls 3a, 3b relative to the temporary fixing member 1. Or move it down. Thus, the mating surface of the temporary fixing material 1 is automatically formed with a welded portion having a desired distance from the upper end to the lower end. 1 shows the case where the temporary fixing material 1 fixedly held on the mounting table 2 is reciprocally moved together with the mounting table 2 during seam welding. However, the seam welding machine itself is reciprocally moved. Good. In this invention, since the temporary fastening material 1 can be automatically seam clad welded in the above-described manner, there is no danger in operation and simple construction is possible.

【Example】

 Width: 1000 mm, length: 2000 mm, thickness: 10 mm A titanium plate with a thickness of 1.0 mm is temporarily fixed to one side of a base plate (SS steel plate) by spot welding, and then shown in Figure 1 above. The temporary tacking material 1 is arranged and fixed on the mounting table 2 of the machine, and continuous automatic seam clad welding is performed under the conditions of pressing force: 400 kg, welding speed: 1,600 mm / min, welding current: 16,000 A. I went. As a result, when the device according to the present invention is used, smooth seam welding can be performed, and the pressing force and welding current may be relatively small compared to the conventional manual method, and the processing can be performed. It was confirmed that the time (welding speed) could be increased by about 1.6 times, and the obtained clad steel sheet was extremely good in terms of quality.
