Abstract
The utility model relates to a screw rod for a plate extruder. The utility model is characterized in that wear-resistant material coating layers are respectively arranged on the working surface of an entire screw edge and the circumferential surface of a rod at the head end region of the screw rod. The wear-resistant material coating layer on the working surface of an entire screw edge is formed by that a plurality of hard metal tips having a spiral shape and fitting the corresponding working surface of the screw edge are smoothly and continuously connected; the wear-resistant material coating layer on the circumferential surface of the rod is formed by that a plurality of hard metal tips having a circular arc shape and fitting the corresponding circumferential surface of the rod positioned at the head end region of the screw rod; the hard metal tips with the two shapes are separately welded with the work surface of the screw edge and the circumferential surface of the rod. Compared with the existing screw rod, the utility model can improve wear resistance, prolong service life, increase production efficiency and reduce operating cost.
Description
The utility model provides the screw rod that uses on a kind of batten extruder.
The screw rod that uses on the existing batten extruder is that the spiral shell rib by the body of rod and body of rod outer peripheral face constitutes, and this spiral shell rib originates in the head end of the body of rod, ends in the tail end of the body of rod.Divide from the angle of working mechanism, screw rod can be divided into extruded segment and feeding section two parts.The head end zone of screw rod is the extruded segment of screw rod, and the end edge region of screw rod is the feeding section of screw rod.This screw rod generally adopts manganese steel material (HRC 〉=60) to make, and the wearing and tearing frequency of extruded segment is fast during work, and degree is also serious, and the wearing and tearing of feeding section are lighter relatively.Wearing no resistance of screw rod, thus cause the service life of this screw rod shorter, and according to statistics, every sub-screw can only be produced 2000 square metres just necessary replacing of batten at most, has so both reduced production efficiency, has strengthened use cost again.
The purpose of this utility model is to provide a kind of batten extruder screw of long service life.
The purpose of this utility model is by providing a kind of batten extruder screw with following structure to realize, this screw rod comprises the spiral shell rib of the body of rod and body of rod outer peripheral face, the spiral shell rib originates in the head end of the body of rod, end in the tail end of the body of rod, the body of rod has the layer that covering of one deck high-abrasive material on the outer peripheral face in screw rod head end zone, the layer that covering of one deck high-abrasive material is also arranged on the working face of whole spiral shell rib.
The outer peripheral face that the described body of rod is in screw rod head end zone is the face of cylinder, and the outer peripheral face that is in the screw rod end edge region is the frustum face.
This batten extruder screw is compared with the batten extruder screw of prior art has following advantage: because the body of rod has the layer that covering of one deck high-abrasive material on the outer peripheral face in screw rod head end zone; the layer that covering that one deck high-abrasive material is also arranged on the working face of whole spiral shell rib; therefore; screw rod is when work; two kinds covering the layer will protect the working surface in screw rod head end zone and the spiral shell rib working face of screw rod end edge region; can improve the wearability of screw rod, thereby effectively prolong the service life of this batten extruder screw.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is the structural representation of this batten extruder screw.
As shown in drawings, the body of rod 1 outer peripheral face of this batten extruder screw has the spiral shell rib of the identical and smooth continuation of pitch, the head end that this spiral shell rib originates in the body of rod is illustrated left end, the tail end that ends in the body of rod is illustrated right-hand member, screw rod is divided into extruded segment from left to right, feeding section two parts, the head end zone of screw rod is the extruded segment of screw rod, the end edge region of screw rod is the feeding section of screw rod, for improving compression properties, the outer peripheral face that the body of rod 1 is in screw rod head end zone is the face of cylinder, the outer peripheral face that is in the screw rod end edge region is the frustum face, the body of rod 1 on the outer peripheral face in screw rod head end zone, have one deck high-abrasive material covering the layer 3, covering layer 3 by the several piece circular shape and can be in the hard metal tip smooth continuation that the corresponding outer peripheral face in screw rod head end zone matches with the body of rod 1 and be formed by connecting, the thickness of several piece hard metal tip is identical, also have on the working face of whole spiral shell rib 2 one deck high-abrasive material covering the layer 4, it is spiral-shaped and can be formed by connecting with the hard metal tip smooth continuation that the corresponding working face of spiral shell rib 2 matches by several piece to cover layer 4, have covering layer 4 spiral shell rib 2 outer cylinder must be through grinding so that outer cylinder measure-alike, the hard metal tip of above-mentioned two kinds of shapes respectively with the outer peripheral face of the body of rod 1, the working face of spiral shell rib 2 welds with brazing, and spiral shell rib 2 height in screw rod head end zone are less than spiral shell rib 2 height of screw rod end edge region.
The material of this batten extruder screw is a carbon constructional quality steel, and the material of two kinds of hard metal tips is the YG serial carbide alloy, and both can use extraordinary mould, adopts the powder metallurgical technique manufacturing.The length in screw rod head end zone is 130mm, constitutes two kinds of hard metal tip thickness covering layer 3, to cover layer 4 in the screw rod head end zone and is 4mm, and constituting the hard metal tip thickness that is covering layer 4 in the screw rod end edge region is 3mm.If when the cemented carbide part sheet influences work because of comparatively serious concentrated wear appears in long-time use back, can change easily.
According to measuring and calculating, this batten extruder screw can be produced the batten more than 10000 square metres, compares with existing batten extruder screw, can improve service life more than 5 times.Because of this, use this batten extruder screw also can enhance productivity, reduce use cost.
