CN2181362Y - Jaw for double bar welder - Google Patents

Abstract

At present, concrete double bars are widely popularized in building trade, and a jaw of a welder has short service life in double bar welding fabricating process because of high temperature and rapid friction. The utility model relates to a jaw for a double bar welder. High strength metal rods are lined in close fit on both sides of a transverse bar slot 2 of the jaw. Because the transverse bar to be welded is only in contact with the high strength metal rods, the service lift of the jaw is increased more than ten times.

Description

Jaw for double bar welder

The utility model relates to a kind of jaw of bi-steel welding machine, the low a kind of jaw of long-life, cost that particularly a kind of heat resistant and wear resistant decreases.

Bi-steel has obtained extensive use in the concrete construction of building trade, but the jaw of bi-steel welding machine in welding process (being the limiting component of horizontal bar) is by special copper alloy manufacturing, involve great expense, because among being operated in high temperature and rubbing fast, wearing and tearing soon, do not guarantee by the perpendicularity of weldering horizontal bar, so need to improve.

Task of the present utility model provides the jaw of the bi-steel welding machine (as the automatic flush welder of USN-50 type bi-steel) that a kind of cost is low, high temperature resistant, wear-resistant, the life-span is long.

The utility model is achieved in that

Only with before the common copper material processing groove the same with original jaw, two sidetrackings, four and half holes at the horizontal bar groove, the degree of depth should surpass the degree of depth of horizontal bar groove, the inboard in hole is just on the sideline of horizontal bar groove, and then in four holes respectively tight fit be bumped into four heat treated carbon steels of process or steel alloy high duty metal rod, and then open the horizontal bar groove, and allow the metal bar of four steel alloys just in time in groove, expose an active line, promptly accuse and finish.

The utility model has following good effect:

1,, do not influence electric conductivity but cost greatly descends because of the matrix material is common copper material.

2, good manufacturability is convenient to processing.

3, high temperature resistant, the wear-resistant life-span greatly improves, and can improve more than ten times approximately at least.

Below in conjunction with accompanying drawing to this practical emerging describing in further detail:

Accompanying drawing is a perspective view of having amplified of the present utility model.

Make matrix 3 with common copper material, be shaped on the horizontal bar groove 2 of working portion in the centre of matrix 3, tight fit studs with high duty metal rod 1 through heat treated carbon steel or steel alloy respectively in the both sides of horizontal bar groove, the length of metal bar 1 should be longer than the degree of depth of horizontal bar groove, must guarantee to expose in the inboard of horizontal bar groove 2 simultaneously the active line 4 of metal bar.Horizontal bar only contacts through heat treated wear-resisting, heat-resisting high duty metal rod 1 during work, so the life-span of this jaw can prolong greatly.

Claims (1)

1. A kind of novel bi-steel welding machine jaw is made up of matrix 3, horizontal bar groove 2 and 1 of several high duty metals rod, it is characterized in that:

   A, have horizontal bar groove 2, stud with several high duty metal rods 1 in the both sides of horizontal bar groove tight fit in the centre of matrix 3;

   The length of b, high duty metal rod is greater than the degree of depth of horizontal bar groove;

   C, expose the active line 4 of high tensile metal rod 1 in the inboard of horizontal bar groove 2.
