いようにしていた。 In the cylinders of twin-screw type resin processing machines used to process resins filled with ceramics, glass fiber, asbestos, etc., and resins with flame retardants added, the inner surface of the cylinder is coated to improve corrosion resistance and wear resistance. Provide a lining layer. Conventional method for forming a lining layer on a twin-tube cylinder
As a method, a lining layer is formed by centrifugally casting a corrosion-resistant and wear-resistant material on the inner diameter of two cylindrical members, and each cylindrical member is longitudinally sectioned along a plane parallel to its central axis. There is a method in which a portion is removed, and then the longitudinal sections of the remaining parts of the cylindrical member are overlapped with each other, and the mating surfaces are joined by gas welding, electric welding, electron beam welding, or the like. In order to prevent the lining layer from cracking due to heat effects during welding, welding was avoided near the lining layer.

合があつた。 However, in such conventional methods, the mating surfaces near the lining layer are not bonded, so corrosive substances generated from the resin material enter through this mating surface, corroding the lining base material and causing the lining layer to cave in. Then, there were cases where a problem occurred.

ば、双筒シリンダ６又は６′が完成する。 First, a reinforcing material (nickel-based self-fusing alloy with corrosion resistance and wear resistance, cobalt-based self-fusing alloy, iron chromium boride, etc.) and a matrix material (nickel-based self-fusing alloy, cobalt-based self-fusing alloy, etc.) and a matrix material (nickel-based self-fusing alloy, cobalt-based self-fusing alloy, etc.) The lining layer 2 is formed by centrifugally casting a composite material consisting of a metal alloy. As a result, a cylindrical member 3 with a lining layer is obtained. Next, this cylindrical member 3 with a lining layer is longitudinally sectioned along a plane parallel to its central axis as shown in FIG. 5 is removed, and an axial groove 4a is formed in the longitudinal section of the large circular arc side portion 4 in the axially perpendicular direction. Note that the groove 4a is for storing excess solder during brazing, which will be described later, and for checking the penetration of electron beam welding or laser beam welding.
The width may be about mm (if the groove 4a is too large, the welded part will become short and there is a possibility that the strength will be insufficient). Furthermore, the wall thickness t between the groove 4a and the outer diameter part of the lining layer 2 is set to a thickness that does not cause the lining layer 2 to crack due to the heat during welding (for example, a thickness greater than or equal to the thickness of the lining layer 2). thickness). Two large arc side portions 4 as described above are created. Next, wax (silver solder, gold solder, brass solder, nickel solder, etc.) is applied to a portion 4b of the longitudinal section of the large arc side portion 4 on the inner peripheral side than the groove 4a, or wax foil is pasted, and two The longitudinal sections of the large arc side portions 4 are superimposed on each other as shown in FIG. 3 and brazed in a vacuum or in a furnace with reducing atmosphere. Next, a portion 4c (hereinafter referred to as a "welding surface") on the outer peripheral side of the groove 4a in the longitudinal section is joined by electron beam welding or laser beam welding. Next, the external shape of the joined bicylindrical body is machined into a desired shape as shown in FIG. 4 (or 5) to complete the bicylindrical cylinder 6 or 6'.

けて割れるといつたこともなくなる。 As explained above, in the manufacturing method of the present invention, the lining layer 2 is formed on the inner diameter portions of the two cylindrical members 1.
Each cylindrical member 3 with a lining layer is longitudinally sectioned along a plane parallel to the central axis, and the small arc side portion 5 of the cross section in the direction perpendicular to the axis is removed, and the longitudinal section of the large arc side portion 4 of the cross section in the direction perpendicular to the axis is removed. A groove 4a extending over the entire length in the axial direction is formed in the groove 4a, and the two large arc side portions 4 are overlapped with each other in their longitudinal sections, and the portion 4b of the inner circumferential surface than the groove 4a of the mating surface is brazed, and the groove 4a of the mating surface is Since the lined twin-tube cylinder is manufactured by welding at the portion 4c on the outer circumferential side of 4a, the vertical sections of the cylindrical members near the lining layer and the lining layers are completely joined together, preventing corrosion. There is no room for sexual substances to enter, and problems that occur when the lining base material corrodes and caves in can be eliminated. In addition, since the welded portion and the lining layer are separated, there is no chance of the lining layer cracking due to the influence of heat.
