Machining method and manufacturing method of air suction grooves of corrugated roller

Abstract

The invention discloses a machining method of air suction grooves of a corrugated roller. The machining method includes the first step of earlier-stage processing specifically involving the processes of a matrix modulation, b primary machining, c tooth punching and d multiplex heat treatment which are conducted on the corrugated roller in sequence, the second step of grinding of the air suction grooves, and the third step of turning of the air suction grooves. The machining method has the beneficial effects that the surface hardness of the roller reaches above HRC62, and the wear life of the roller is prolonged by 30%; the corrugated roller is uniform in surface hardness and free of soft zones; in the using process, neither pocking marks nor concave pits occur; due to the fact that hardening treatment is conducted at first and then the grooves are cut, the hardness of groove openings is consistent with the hardness of other positions, and the defect that poor gluing of paper boards is caused by quick abrasion to the groove openings, tooth breakage and other reasons is avoided in the using process.

Description

technical field [0001] The invention relates to the technical field of production and processing of corrugated rollers, in particular to a method for processing a suction groove of a corrugated roller and a manufacturing method thereof. Background technique [0002] The corrugating roll is the heart part of the corrugated cardboard production line-the heart of the corrugating machine. The manufacturing accuracy and service life of the corrugating roll will directly affect the production efficiency and production cost of the user. In other words, a well-made corrugating roll part will directly bring economic benefits to the user. Therefore, the design and manufacturing process of corrugated rollers has always been an important topic for domestic and foreign manufacturers to tirelessly pursue improvement and improvement. [0003] The corrugated cardboard production line consists of multiple single machines, among which the corrugating machine is a core. The function of the c...

Problems solved by technology

Advantages of the traditional processing method: 1. Low cost, high efficiency, convenient and fast processing, 2. High groove precision and few types of cutters; however, the traditional processing method also has many shortcomings, such as: 1. After the suction groove is processed, When the corrugated roller is hardened by intermediate frequency quenching, due to the existence of the suction groove, the suction groove is prone to chipping, soft bands, and uneven hardness. The mouth wears and the bell mouth appears, resulting in poor glue on the cardboard and uneven height of the cardboard; 2. Due to the existence of grooves, it is easy to occur during heat treatment, and processing risks such as deformation of the roller and uneven heating and cracking cause the corrugated roller to be scrapped
