Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] Such as figure 1 , 2 As shown, the special-shaped support mandrel in this embodiment is used for forming the steel mesh skeleton, and includes a horizontally arranged support shaft body 1. The extension direction of the support shaft body 1 is consistent with the pulling direction of the supporting steel wire layer of the steel mesh skeleton. , the outer peripheral surface of the supporting shaft body 1 is evenly provided with a number of semi-slots a extending in the axial direction, the number of the half-slots a is equal to the number of parallel steel wires supporting the steel wire layer, and the parallel steel wires are embedded in the aforementioned half-slots one by one. In a, under the action of traction, the supporting steel wire layer can move forward continuously along the half groove a.
[0016] Further, adjacent half-gro...

The invention relates to a special-shaped supporting mandrel for forming a steel wire gauze framework. The special-shaped supporting mandrel comprises a supporting mandrel body. The extending direction of the supporting mandrel body is identical with the traction direction of a supporting steel wire layer of the steel wire gauze framework, a plurality of semi-grooves extending in the axial direction are evenly formed in the outer circumferential face of the supporting mandrel body, a plurality of steel wires forming the supporting steel wire layer are embedded in the semi-grooves in a one-to-one correspondence mode, and the supporting steel wire layer can move forwards along the semi-grooves under the action of traction force. Furthermore, a strip-shaped plane is formed between every two adjacent semi-grooves so as to maintain the state that a middle winding steel wire layer spirally wound on the supporting steel wire layer is not in contact with the supporting mandrel body all the time. The special-shaped supporting mandrel provides supporting action for the innermost supporting steel wire layer of the steel wire gauze framework, the winding steel wire layer is spirally wound on the supporting steel wire layer in sequence in the forward traction process, and supporting is provided for consecutive work of forming of the steel wire gauze framework.
Description
technical field [0001] The invention relates to a special-shaped supporting mandrel produced by forming a steel wire mesh skeleton. Background technique [0002] Steel mesh skeleton plastic pipes have higher strength than ordinary plastic pipes and withstand higher pressures. They are widely used in urban water supply, gas, special industrial fluids such as petroleum, chemical flow agents, ore pulp, industrial wastewater, solid powder, low-temperature liquids High pressure piping systems. [0003] The most commonly used wire mesh skeleton is a spiral grid form. The invention patent of the authorized announcement number CN202612888U discloses a new type of steel mesh skeleton plastic composite pipe, including an outer plastic layer, a steel mesh skeleton and an inner plastic layer; the steel wire The mesh skeleton includes a grid-shaped skeleton formed by winding left-helical steel wires and right-helical steel wires; one side of the steel mesh skeleton is provided with stee...
