Production process of thin-wall large-diameter high-strength non-metal carrier roller

Abstract

The invention discloses a production process of a thin-wall large-diameter high-strength non-metal carrier roller. The process comprises the following steps that 1, carrier roller shell material is prepared, non-metallic material is added into an extruder, and a carrier roller shell material pipe is obtained through melt extrusion, vacuum shaping and cooling; 2, a shell part machining, mechanicalmachining is carried out on the two ends of the carrier roller shell material pipe according to requirements of customer drawing paper and assembly technology, and the shell part is manufactured; 3, acarrier roller is assembled, a special carrier roller press-fitting machine is used, a bearing chamber, a bearing and a sealing element are combined and pressed on the inner side of the shell part, and the carrier roller production is completed; and 4, checking is carried out. The production process of the thin-wall large-diameter high-strength non-metal carrier roller has the advantages that theweight is reduced, the raw material consumption is reduced, and the cost is reduced; the mechanical strength is high, so that the problem of stress deformation of a long carrier roller is solved; thelabor intensity of field operators is reduced; and wear resistance, acid and alkali resistance are achieved, the production process is suitable for a mine environment with sulfur-containing burstingwater, and is flame-retardant and antistatic.

[0002] Coal mine underground belt conveyor is also called belt conveyor or belt conveyor. Belt conveyor is a tractive continuous transportation equipment with a wide range of uses. It is suitable for coal, metallurgy, mining, ports, building materials, chemical industry, light industry, Various industries such as petroleum, transportation, etc., can be used to transport bulk, granular and bulk materials; the core component is the roller; and there are many types of non-metallic rollers for underground coal mines, such as Chinese patent application number: 201120161734. X, discloses a non-metallic idler roller for underground coal mines, the steel roller shaft (8) is set in the middle of the antistatic non-metallic rod body (1), and the non-metallic bearing seat (2) is inserted in the antistatic non-metallic rod body In the expansion port of the double-sealed bearing (3), the outer edge and inner wall of the double-sealed bearing (3) are closely connected with the inner wall of the non-metallic bearing seat and the outer edge of the reduced-diameter section (15) at the end of the roller shaft, and a circlip is arranged on the outer side of the double-sealed bearing (7), a seal ring is set on the roller shaft end shrinkage section on the outside of the circlip, and a non-metallic end cover (11) is provided on the outside of the seal ring, and a non-metal end cover is provided on the outside of the seal ring; the utility model The main structure is made of antistatic non-metallic rods, non-metallic bearing seats, and non-metallic end caps to ensure that the idler does not generate static electricity during operation; the sealing ring uses a labyrinth structure, and dust and other sundries are difficult to enter Or come into contact with double-sealed bearings; but it cannot solve the problem of force deformation of long idlers; and its wear resistance and acid and alkali resistance are general
