Abstract

The utility model relates to an alloy body welding structure; the alloy welding structure is welded in a tapered pick and tapered engineering tool product with braze welding technology, and is mainly used for engineering machinery, ore exploitation and coal mine collection; and the structure comprises a cylindrical alloy body, a plurality of clearance adjusting ribs for outer surface welding seams and a plurality of clearance adjusting ribs for bottom surface welding seams. The alloy body welding structure is characterized in that the plurality of clearance adjusting ribs for the outer surface welding seams and the plurality of clearance adjusting ribs for the bottom surface welding seams are added on the basis of the original hard rock pick alloy so as to form novel hard rock pick alloy; when the structure is welded with a pick body, the number of clearance adjusting ribs for alloy welding seams, the number of adjusting points, and the semi-diameter and thickness sizes required are scientifically selected, thereby being capable of guaranteeing correct and uniform joint clearance and also guaranteeing accurate welding position of alloy and the pick body so that a braze welding material can be uniformly and efficiently filled in the welding seams formed between the alloy and the pick body; therefore, the alloy welding strength is improved, and the service life of the pick is prolonged. The structure can be widely applied to various pick products.

Description

The alloy body welded construction

Technical field

The utility model belongs to the conical pick field, comprises taper engineering cutter.

Background technology

Conical pick in the market, because former cylinder alloy the time can not be controlled the play movement uniformly and effectively for welding, cause that easily gold alloy solder tipping timing position is crooked, and the play movement is filled not full during welding, cause the alloy welding insecure, when pick is operated in the hard formation cutting, because alloy and hard rock produce violent fricting movement, it is inclined to one side that the crooked alloy mill that makes is easily put in gold alloy solder tipping coordination, serious wear; Alloy welds when insecure, causes that easily alloy comes off, and causes pick to be scrapped, and adds weld gap and adjusts rib and adjust point and can control the play movement uniformly and effectively, and accurately the alloy rigging position is further strengthened the alloy weld strength, prolongs pick application life.

Summary of the invention

The purpose of this utility model is for overcoming the existing product unreasonable structure, and play movement control is bad, and the position is crooked when causing assembling, not prison welding is solid, and a kind of structure uniqueness is provided, and the alloy welding is not crooked, firm welding is difficult for the novel alloy body welded construction that causes that alloy comes off.

The utility model is achieved in that

The utility model is flat or bore end cylinder alloy body (1), rib (2), bottom surface weld gap adjustment point (3) composition are adjusted in the fillet in parallel shear gap, main feature is to add the novel pick alloy that weld gap is adjusted rib and bottom surface interpolation weld gap adjustment point in the outside of cylindrical alloy, mainly be welded on the conical pick by the soldering welding procedure, it is characterized in that, rib is adjusted in the fillet in parallel shear gap of external surface interpolation more than three or three at above-mentioned cylinder alloy body (1), and the weld gap adjustment point that can add in the bottom surface more than three or three is formed.

Because soldering is to make liquid solder fill up play movement between object by capillarity, therefore must correctly select the gap of joint, the size in gap, well-balanced densification and the strength of joint that influences brazed seam to a great extent, the gap is too little, the obstruction solder flows into, and causes slag inclusion or incomplete penetration in the brazed seam; Excesssive gap, the capillarity of destruction brazed seam, solder can not fill up the gap.

Above-mentioned (1), (2), (3) parts can adopt following layout architecture:

1, on flat or awl end cylinder alloy body (1) side, adds weld gap bar shaped rib (2), the bottom surface can be added weld gap and be adjusted point (3), and the bar number of weld gap bar shaped rib can carry out the science adjustment with number 〉=3 of adjusting point and bar shaped rib according to radius, the thickness of alloy with radius, the thickness of adjusting point.

2, go up interpolation weld gap circumferential rib (2) at flat or awl end cylinder alloy body (1), the bottom surface can be added weld gap and be adjusted point (3), and the science adjustment can be carried out according to radius, the thickness of alloy with number 〉=3 of adjusting point and radius, the thickness of circumferential rib and adjustment point in the number of rings of weld gap circumferential rib 〉=2.

3, go up interpolation weld gap spiral ribs (2) at flat or awl end cylinder alloy body (1), the bottom surface can be added weld gap and be adjusted point (3), and bar number 〉=1 of weld gap spiral ribs can rationally be adjusted according to radius, the thickness of alloy with number 〉=3 of adjusting point and radius, the thickness of spiral ribs and adjustment point.

After the utility model adopts said structure, than other constructional alloy more science, rationally, effectively regulate and control the play movement, accurately the welded and installed position with the weld strength of further reinforcement alloy, prolongs the application life of pick.

The specific embodiment

Below in conjunction with accompanying drawing example of the present utility model is elaborated.

As accompanying drawing Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is a kind of novel alloy body welded construction, wherein flat or awl end cylinder alloy body (1) is used for cutting, digging action, the fillet in parallel shear gap is adjusted rib (2) and is used to adjust the effect of joint crack, and bottom surface weld gap adjustment point is used to adjust the play movement effect.

This structure can be widely used in all kinds of pick products.
