Embossed stainless pipe manufacturing apparatus and embossed stainless pipe manufacturing method using same

Abstract

The present invention relates to an embossed stainless pipe manufacturing apparatus which in general allows forming of an embossed stainless plate so as to enable efficient welding of the embossed stainless plate, selecting of a welding means appropriate for the forming, and introduction of an electric tempering furnace which facilitates manufacturing of an embossed stainless pipe by means of a thick stainless plate, and to an embossed stainless pipe manufacturing method having enhanced welding method by means of a magnetic material melt welding method so as to be suitable for an embossed stainless pipe which requires narrow, precise and accurate welding.

Description

technical field [0001] The present invention is aimed at the "making embossed stainless steel plate Perfection and improvement of embossed stainless steel pipe manufacturing device with easy welding on both sides and embossed stainless steel pipe manufacturing method using the same, [0002] More specifically, in the embossed stainless steel pipe manufacturing device, it relates to a cutting device (Slitting machine), which solves the problem that it is difficult to set the required width of the stainless steel flat plate that meets the outer diameter of the pipe, and cuts the wide stainless steel flat plate (Slitting machine). ) into a plurality of flat plates, so that the side of the stainless steel flat plate after cutting (Slitting) is formed vertically, and relates to an embossed stainless steel pipe manufacturing device. It can be carried out smoothly, and the tempering electric furnace is introduced to form an overall structure. [0003] In addition, it relates to a m...

Problems solved by technology

[0022] Second, the thickness of the embossed stainless steel plate is usually 0.5mm-5mm, and the degree of embossing is within 1.5 times of the thickness of the stainless steel plate. However, the stainless steel plate of at least 2.5mm or more causes unreasonable use of the embossing roller. , Compared with the embossed stainless steel plate processed by the thin film stainless steel plate, the sharpness and fineness of the embossed pattern engraved by Yin and Yang are reduced

[0023] Use a soft stainless steel plate with low hardness to compensate for the delicacy and sharpness, but the hardness of the embossed stainless steel plate after embossing is greatly increased, and the tensile and bending degrees are increased due to the large thickness of the stainless steel tube. The pipe rolling machine cannot be smoothly curved and rounded, and not only requires a lot of power, but the pipe rolling machine may even stop operating. Therefore, it is necessary to restore the hardness of the raised embossed stainless steel plate to the original embossed through heat treatment (Tempering) Soft hardness before processing

[0024] Third, the embossed stainless steel plate inserted into the rolling mill after the embossing roller is embossed is inserted between the male roller with a raised curved surface arranged horizontally along the upper and lower sides and the female roller with a concave curved surface, the adjustment and fixation of the interval formed In the case of using a stainless steel plate to manufacture a stainless steel smooth surface tube through a pipe rolling mill, a stainless steel plate is inserted between the curved male and female rolls, and the screw fixing device is used to make it tight by the self-weight of the upper male roll. The interval between the male and female rollers is fixed so that it can be curved and rounded, but the embossed stainless steel plate has elasticity by corresponding to the positive embossed pattern formed on the back, so that Spacing adjustments are quite different from male and female surfacer rollers for surfacer stainless steel flats

[0025] Fourth, in the adjustment of the interval between the curved male and female rollers of the embossed stainless steel flat plate, the embossed stainless steel plate is inserted between the curved male and female rollers, and the self-weight of the curved male roller makes it on the female roller In the tight state, the distance is further reduced, which is equivalent to the size in the range of 10% to 15% of the size increased by embossing, and adjusted so that it is fixed, and then curved and rounded. In the tight state, if If the interval is not reduced, the idling of the surfacing roller and the rounding roller may occur, and the surfacing and circularization will not proceed smoothly. If the interval is excessively reduced, the embossing pattern may be deformed, resulting in poor embossed stainless steel pipe
