Abstract
The invention discloses a manufacturing process of a dual-metal belt saw. The manufacturing process comprises the following steps: (1) quenching and tempering a dual-metal saw blade back material in a lead bath; (2) performing butt welding on an M42 high-speed steel bar and the back material through a laser welding machine to obtain a bar; or performing butt welding on a tungsten-cobalt alloy and the back material for shaping; (3) grinding saw teeth on the welded dual-metal saw belt; (4) directly feeding the tooth-ground tungsten-cobalt alloy dual-metal belt saw into a steel belt tempering furnace for tempering at the temperature of 200-350 DEG C; or performing a saw setting process on the tooth-ground high-speed steel belt saw, and feeding into the steel belt tempering furnace for tempering at the temperature of 200-350 DEG C. According to the manufacturing process, the dual-metal belt saw back material is quenched and tempered in the lead bath firstly, so the till the texture reaches tempering troostite and the hardness is up to HRC (Rockwell Hardness) 47-48 degrees; high-speed steel or the tungsten-cobalt alloy is welded with the back material through laser welding, and tooth grinding, saw setting and super-high-frequency quenching and tempering of teeth are performed, so that the back material and high-speed steel or tungsten-cobalt alloy teeth of the final dual-metal belt saw can reach respective reasonable application standards.
Description
Technical field
The present invention relates to a kind of manufacture craft of bimetal bandsaw.
Background technology
Traditional bimetal bandsaw adopts cold rolling material and high speed steel material, first with electron beam welding, connects and uses tooth milling machine mill teeth again, and then heat treatment, finally carries out roll flute, and this kind of processing technology makes bimetal bandsaw backing often can not reach use standard, and tensile strength is inadequate.
Summary of the invention
For above-mentioned weak point of the prior art, the present invention aims to provide a kind of manufacture craft of bimetal bandsaw, makes bimetal bandsaw backing and high-speed steel or tungsten-cobalt alloy tooth reach the standard of rationally using separately, has improved tensile strength.
To achieve these goals, technical scheme of the present invention: a kind of manufacture craft of bimetal bandsaw, it comprises the following steps,
1), by bimetal saw blade backing patenting, tempering;
2), M42 high-speed steel bars and backing are passed through to laser-beam welding machine butt welding slivering; Or tungsten-cobalt alloy and backing butt welding are shaped;
3), the bi-metal bandsaw blades after welding is carried out to saw gumming;
4), the tungsten-cobalt alloy bimetal bandsaw after roll flute is directly sent into tempering in steel band tempering furnace, 200 ℃～350 ℃ of temperatures; After being dialled to road technique, high-speed steel band saw after roll flute sends into again tempering in steel band tempering furnace, 200 ℃～350 ℃ of temperatures.
Further, carrying out before patenting in described step 1), bimetal saw blade backing should preheat processing.
In described step 1), bimetal saw blade backing carries out after patenting, tempering, requires tissue to reach secondary troostite, and hardness reaches HRC47～48 degree.
Saw gumming in described step 3) adopts metal wheel to grind corresponding profile of tooth by automatic toothing machine.
Described step 4) is carried out hyperfrequency quenching, tempering to tooth portion in steel band tempering furnace.
Described step 4) tempering is by check, packing.
Beneficial effect of the present invention: bimetal bandsaw backing is first after patenting, tempering, make its tissue reach secondary troostite, hardness reaches HRC47～48 degree, and then high-speed steel or tungsten-cobalt alloy and backing are connected by Laser Welding, last roll flute, dial road and tooth portion through hyperfrequency quench, tempering, make the backing of the bimetal bandsaw that finally makes and high-speed steel or tungsten-cobalt alloy tooth can reach reasonable use standard separately.Solved in traditional manufacturing technique and occurred that backing can not reach use standard, the defect that tensile strength is not strong.

The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, further describe the present invention.
A manufacture craft for bimetal bandsaw as shown in Figure 1, it comprises the following steps,
1), by bimetal saw blade backing patenting, tempering;
Specifically by discharging frame 1 and plait mill 5, realize bimetal saw blade backing automatically moving ahead in whole quenching, tempering process, in this quenching, tempering process, comprise respectively heating furnace 2, lead quench groove 3 and tempering furnace 4, wherein, lead is quenched groove 3 for bimetal saw blade backing is carried out to patenting, 4 pairs of bimetal saw blade backings of tempering furnace carry out tempering, before carrying out patenting, by 2 pairs of bimetal saw blade backings of heating furnace, preheat processing.Workflow is, by plait mill 5 scrolling bimetal saw blade backings, bimetal saw blade backing is preheated in heating furnace 2, then plait mill 5 carries out coiled strip, making part bimetal saw blade backing after preheating enter lead quenches in groove 3 and carries out patenting, afterwards, scrolling again, the bimetal saw blade backing after patenting enters and in tempering furnace 4, carries out tempering.Bimetal saw blade backing, after patenting, tempering, requires tissue to reach secondary troostite, and hardness reaches HRC47～48 degree.
2), M42 high-speed steel bars and backing are passed through to laser-beam welding machine 6 butt welding sliverings; Or tungsten-cobalt alloy and backing butt welding are shaped;
3), the bi-metal bandsaw blades after welding is carried out to saw gumming, in this example, by automatic toothing machine 7, adopt metal wheels to grind corresponding profile of tooth;
4), the tungsten-cobalt alloy bimetal bandsaw after roll flute is directly sent into tempering in steel band tempering furnace 9,200 ℃～350 ℃ of temperatures; Or after being dialled to road technique, the high-speed steel band saw after roll flute sends into again tempering in steel band tempering furnace 9,200 ℃～350 ℃ of temperatures.
The automatic poking road machine 8 of the external import of described Bo road process using is dialled road, and Gai Bo road technique is, band saw sawtooth is set right along inclined, and such as sawtooth is on one side toward left bank, another side, toward right bank, makes it become sawtooth normal operating condition.
And described tempering for to carry out hyperfrequency quenching, tempering to tooth portion in steel band tempering furnace 9, make tooth portion reach good result of use.
