Spiral machine head body

Abstract

The invention discloses a spiral machine head body, and relates to the technical field of pipe machining. The spiral machine head body comprises a spiral body, a machine head sleeve is fixedly arranged on the outer wall of the spiral body, an adjuster is movably arranged on the outer wall of the machine head sleeve, a clamping hole is formed in the outer wall of the adjuster, a clamping block is movably arranged on the inner wall of the clamping hole, a containing groove is formed in the top of the spiral body, and a limiting block is movably arranged on the inner wall of the containing groove. By arranging two discharging ports, raw materials enter the spiral body to be spiral, then the formed raw materials can be obtained through pressure preparation of a pressure preparation section structure, the overall machining efficiency is improved, a feeding section communicates with the pressure preparation section through movable arrangement of an extrusion rod, the raw materials can be conveyed normally, the pressure preparation section and an air outlet channel which are located on the same vertical plane can play the structural convenience in the machining process, so that the device can share the internal pressure, the internal structure is high in pressure sharing capacity, and the raw materials are uniformly produced.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a screw head body. Background technique [0002] The cooling of the screw head generally adopts natural cooling or oil cooling. When producing a pipe with a specific formula and the extrusion volume is large, the temperature of the mandrel and the spiral body will rise, which will easily lead to premature aging of the inner wall. With natural cooling, the heat exchange is insufficient, the cooling speed is too slow, and the temperature fluctuates violently. [0003] The currently used screw head body is easy to accumulate a lot of heat during the pipe processing, which affects the quality of raw material production, and the ordinary screw head body is a fixed structure, which is not conducive to people's installation and disassembly, so that the local structure fails. Or it is not conducive to replacement after wear and tear, which increases the cost and increases the w...
