Abstract

A non-filling welding technique which is provided with circular arc surface made of carbide alloy with circular arc surface welded seam and saw teeth adopts circular shaped carbide alloy which is welded to machine-shaped fine spring steel of the saw back via non-filling high-speed automatic welding mode. The spring steel is formed into serrated shape via a high-speed automatic abrading process, which has the advantages that on one hand special location is not necessary for the circular shaped carbide before weld, thereby simplifying the manufacturing technique, promoting the production benefit and reducing the manufacturing cost, and on the other hand the circular shaped carbide alloy has the maximal welding area, which has precise location, costs minimal heat stress, and has the greatest welding strength.

Description

Have exempt to fill, the arc surface carbide alloy ribbonsaw teeth of arc surface weld seam

Affiliated technical field

The utility model belongs to the bands for band that cuts each metalloid, especially cuts high shear force, low conductivity, anti abrasive material, and tooth portion material is the bimetal bandsaw of carbide alloy.

Background technology

The bimetal bandsaw that cutting metal is used comprises backing and tooth portion, the spring steel material of material selection high-quality, and tooth portion selects high-speed steel or Hardmetal materials for use.The manufacturing process maturation of high-speed steel bimetal saw blade and circular saw, simple to operate, but Red Hardness of High Speed Steel, mar proof shortcoming such as unsuitable high-speed cutting is unconquerable again.The number of patent application that existing hard alloy band saw blade and circular saw such as Patent Office of the People's Republic of China announce is 99242087.3 disclosed patent documentations; production technology is single ring-type; soldering is adopted in welding; sawtooth head complex-shaped; grinding process is many and complicated, therefore is difficult to the production of low cost, scale.

Summary of the invention

The purpose of this utility model just provides a kind of carbide alloy of optimizing structure that has, and it can high efficiencyly be welded on the band saw.

Technical scheme of dealing with problems of the present utility model is: a kind of carbide alloy, comprise an arc surface, and angle, two front and back grinding face, the center line of described arc surface overlaps with the center line of angle, two front and back grinding face; The angle grinding face is two planes before and after two; The thickness of described carbide alloy is bigger or less than the thickness of band saw backing; Intersect a suitable angle between the grinding face of angle, described front and back, described angle is that 50 degree are to 68 degree; Described arc surface have with band saw on the approaching installation radius in installation position.

The beneficial effects of the utility model are: because its manufacturing process is greatly simplified, improved productivity effect, reduced manufacturing cost; Yuan Xing carbide alloy has maximum bonding area on the other hand, and the location is the most accurate in the mill, and thermal stress is minimum again, and weld strength is the highest.

Be labeled as shown in the accompanying drawing: 1: carbide alloy, 3: angle, front and back grinding face, 4: arc surface.

The specific embodiment

Now describe concrete device and the implementation detail that the utility model proposes in detail with regard to above-mentioned accompanying drawing.As shown in Figure 1 and Figure 2, it is the feature that carbide alloy of the present utility model (1) is had before installation, it is the round of a standard in the side-looking direction, and extending to its vertical direction, formed height is bigger or less than the thickness of band saw backing, the installation radius that the radius of its round and the installation position on the band saw are approaching.This structure has remarkable advantages aspect installation, in the installation as automation or semi-automation, after screening, need not product is located especially to carbide alloy (1), just can be installed to the installation position on the band saw accurately, and because it is the round of a standard, its thermal stress all around is also basic identical after welding, thereby has improved the qualification rate of its product.

Then, make profile of tooth by fast automatic grinding process, as shown in Figure 3, Figure 4.Carbide alloy after the grinding (1) has following feature: comprise an arc surface (4), and two front and back angle grinding faces (3), the center line of described arc surface (4) overlaps with the center line of two front and back angle grinding faces (3); Angle grinding face (3) is two planes before and after two; The thickness of described carbide alloy (1) is bigger or less than the thickness of band saw backing; Intersect a suitable angle between angle, the described front and back grinding face (3), described angle is that 50 degree are to 68 degree, to improve its cutting efficiency; Described arc surface (4) have with band saw on the approaching installation radius in installation position.

At last, by automation or semi-automatic device the tooth portion of band saw is carried out well-regulated minute tooth, thereby reach the purpose of this utility model.

Because carbide alloy (1) has regular circular before welding, thereby need not locate especially, and has omitted the welding filler in welding, this requires to have reduced to the automation of equipment on the one hand, thereby has reduced cost; Improve working efficiency on the other hand, helped the batch process of scale simultaneously.

A kind of band saw with carbide alloy (1) tooth portion can be provided thus, and this band saw can be at a high speed, the low heat conduction power of efficient, high-quality cutting and anti abrasive material.Though the utility model is by detailed being described of the foregoing description, under the situation that does not change the utility model general idea can on content do suitable adjustment, the scope of its adjustment also will fall in the protection domain of the present utility model.
