Abstract
The utility model discloses a bimetallic screw which is characterized in that a surface of a spiral shell of the screw I, which contacts with a material injection pipe, is provided with a spiral groove; and nickel base alloy powder is welded in the spiral groove. Firstly, the groove is arranged on the surface of the spiral shell, which contacts with the material injection pipe; and then nickel base alloy powder is welded in the groove through a welding machine. In this way, when the screw rotates, nickel base alloy powder is on the surface of the spiral shell, which contacts with the material injection pipe, and since the nickel base alloy powder is high in hardness, the shell is not easy to wear and tear, thus effectively improving the service life of the screw and reducing the using cost of the screw. The service life of the screw is 3-5times that of a common screw.
Description
Technical field
The utility model relates to a kind of screw rod, particularly a kind of screw rod that is applicable to make-up machine at the bottom of the Automatic Plastic rubber overshoes.
Background technology
Plastic rubber ejection shaping apparatus is when plasticizing, and the interior raw material of pipe that needs to shoot material is delivered to injection port from feeding mouth.The pipe that shoots material is provided with a screw rod to be used to promote raw material and to advance, and screw rod otherwise stall is moving can evenly plastify raw material, the former fluid state that keeps when expecting injection port.Existing screw rod is when rotating, and the direct contact friction of tube wall of its lip-deep spiral shell and the pipe that shoots material was used after a period of time, screw rod spiral shell serious wear, and the spiro rod plasticizing ability descends greatly, and until scrapping, the service life of screw rod is very short.Plastic rubber ejaculate molding is when injection moulding, and the screw rod consumption is big, has also increased the cost of injection mo(u)lding.
The utility model content
The purpose of this utility model is to overcome the prior art defective, when providing a kind of and plastic rubber ejaculate molding to shoot material the tube wall friction, and the bimetallic screw rod of not easy to wear, long service life.
In order to realize above purpose, the utility model by the following technical solutions: a kind of bimetallic screw rod is characterized in that: screw spiral type spiral shell offers a spiral type groove with the surface that the pipe that shoots material contacts, and is welded with nickel-base alloy powder in this spiral type groove.
The beneficial effects of the utility model are: the utility model offers a groove the screw type spiral shell with the surface that the pipe that shoots material contacts earlier, and then welds nickel-base alloy powder with bonding machine in groove.Like this, when screw rod rotated, the screw type spiral shell was a nickel-base alloy powder with the surface that the pipe that shoots material contacts, and owing to the hardness of nickel-base alloy powder is very high, so spiral shell is not easy to wear, in the service life of effectively having improved screw rod, had reduced the use cost of screw rod.Be 3～5 times of common screw service life of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A direction schematic diagram of Fig. 1;
Fig. 3 is the effect schematic diagram after interior nickel-base alloy powder of groove and tube wall polish;
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of bimetallic screw rod, bimetallic screw spiral type spiral shell 2 offers a spiral type groove 1 with the surface that the pipe that shoots material contacts, and described spiral type groove 1 is the curved groove of a cross section, is welded with nickel-base alloy powder in this spiral type groove 1.
The utility model offers a spiral type groove 1 screw type spiral shell 2 with the surface that the pipe that shoots material contacts earlier, and then welds nickel-base alloy powder with bonding machine in spiral type groove 1.Like this, when screw rod rotated, screw type spiral shell 2 was a nickel-base alloy powder with the surface that the pipe that shoots material contacts, and owing to the hardness of nickel-base alloy powder is very high, so spiral shell 2 is not easy to wear, in the service life of effectively having improved screw rod, had reduced the use cost of screw rod.Be 3～5 times of common screw service life of the present utility model.
