Abstract
A disclosed rubber extruding machine screw comprises a thread part and a transmission part; the thread part comprises a plasticizing segment and an extruding segment; along the direction from the transmission part to the extruding segment, the plasticizing segment is successively divided into a first thread segment with the length of 1200 mm, a second thread segment with the length of 200 mm, a third thread segment with the length of 1000 mm, a forth thread segment with the length of 200 mm, a fifth thread segment with the length of 1000 mm and a sixth thread segment with the length of 200 mm; the pitch of the first thread segment to the forth thread segment is 200 mm, the pitch of the fifth thread segment is 150 mm, and the second thread segment, the forth thread segment and the sixth thread segment are mixing thread segments with the pitch of 500; and the bottom diameter of the first thread segment to the sixth thread segment is 130.7 mm, the initial bottom diameter of the extruding segment connected with the sixth thread segment is same to that of the sixth thread, and the bottom diameter of the rear part of the extruding segment is gradually expanded to 160 mm. The rubber extruding machine screw is simple, compact and reasonable in structure, is reasonable in structure distribution of the functional segment, is improved in integral strength, helps to realize manufacturing and usage of a rubber extruding machine screw with a high length-diameter ratio (such as 25:1), and is convenient to assemble.
Description
Technical field
The present invention relates to a kind of rubber extruding machine accessory, be specifically related to a kind of rubber extruding machine screw rod.
Background technology
Rubber Extruder is a kind of common device for the production of cabtyre cable, and the screw rod index of rubber extruding machine has draw ratio and compression ratio etc.Draw ratio (L/D) is the key factor of spiro rod plasticizing ability and effect, L/D greatly material time of staying in machine barrel long, be conducive to plasticizing, pressure current, leakage current reduce simultaneously, improved plasticizing capacity, the material of simultaneously Temperature Distribution being had relatively high expectations is favourable, but after large, to manufacturing in assembling use, there is again negative effect, general L/D is (18～20), if will improve draw ratio again, screw rod easily fractures during fabrication, and assemble more difficultly, cause the plasticizing capacity of extruded highly dense solidity rubber to be difficult to guarantee.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easily manufactured, steadiness is high, the rubber extruding machine screw rod of high length-diameter ratio.
A rubber extruding machine screw rod, comprises threaded portion and driving section, and threaded portion comprises fluxing zone and extruding zone, described fluxing zone from driving section toward extruding zone direction, being divided into successively length is the first thread segment of 1200mm, length is the second thread segment of 200mm, length is the 3rd thread segment of 1000mm, length is the 4th thread segment of 200mm, length is the 5th thread segment of 1000mm and the 6th thread segment that length is 200mm, wherein, the pitch of above-mentioned first to fourth thread segment is 200mm, the pitch of the 5th thread segment is 150, above-mentioned second, four, six thread segments are that pitch is 500 kneading screw section, the footpath, the end of the above-mentioned first to the 6th thread segment is identical, for 130.7mm, the footpath, the initial end of extruding zone joining with the 6th thread segment is identical with the 6th thread segment, at the bottom of back segment, footpath increases successively, until 160mm.
The length of described extruding zone is 1200mm, and pitch is 200.
The present invention is simple in structure, and compact and reasonable is focused on the distribution rational in infrastructure of functional section, has improved bulk strength, and can realize the manufacture of the rubber extruding machine screw rod of high length-diameter ratio (as 25:1) and use, and easy to assembly, safe and reliable.
