Welding rod spiral extrusion press with double-fastened reamer head

Abstract

The invention provides a welding rod spiral extrusion press with a double-fastened reamer head. The welding rod spiral extrusion press comprises a powder cylinder with a powder-feeding inlet, a spiral reamer, a power source and a wire-feeding mechanism; the spiral reamer is arranged in the powder cylinder; the power source is connected with the spiral reamer; the wire-feeding mechanism is communicated with the powder cylinder; and the head of the spiral reamer is double-fastened. The invention has the following advantages that: the capacity is 25 percent higher than before; a bamboo stick is not needed any more to push powder into the powder cavity of the cylinder, and thereby the labor intensity of power feeding is reduced; the power-feeding skill can be skillfully mastered after three days of training; operation is simple; the service lives of the parts are prolonged; since the head of the spiral reamer is double-fastened, the rotating speed of the reamer is reduced, the service lives of the parts are prolonged, the average service life of the powder cylinder is about 15 days, the average service life of the spiral reamer is about 7 days, the powder cylinder can be repetitively repaired and used, consequently, the expense on the parts is reduced, and more than 200,000 yuan can be saved annually.

Description

technical field [0001] The invention relates to a welding rod spiral coating machine for coating welding core powder in the welding rod industry, in particular to a welding rod spiral coating machine with a double-button reamer head. Background technique [0002] At present, in the welding rod industry, the commonly used equipment for coating powder on the surface of the welding core is a screw press coating machine. [0003] Such as figure 1 As shown, the structure of the screw press coating machine in the prior art includes: a medicine powder cylinder liner 7, and the upper end of the medicine powder cylinder liner 7 is provided with a continuous drug opening 6; a single-head spiral reamer 2 arranged in the medicine powder cylinder 7; One end is connected to the transmission main shaft 1 of the reducer, and the other end of the helical reamer 2 is adjacent to the wire feeding mechanism. The wire feeding mechanism includes: a wire guide 5 and a sizing die 3, the wire guid...

AI Technical Summary

Problems solved by technology

[0006] 1). Low production capacity: Taking Ф3.2 as an example, the design shift output is 8 tons / shift, and the actual output can reach 11 tons / shift

[0007] 2). Continuing the medicine is labor-intensive: manual labor needs to keep pounding the medicine powder with a bamboo stick to increase the thrust so that the medicine powder enters the powder chamber of the machine cylinder

[0008] 3). Difficult to operate: It takes at least 6 months to master the skill of refilling medicine

[0009] 4). Short service life of spare parts: the average service life of powder cylinder liner is about 7 days (21 shifts), and the average service life of spiral reamer is about 3.5 days (10.5 shifts).
