Forming method to existing steel wire mesh frame is optimized, and the selve support intensity for improving steel wire mesh frame is ability
Field technique personnel need one of problem of thinking.
Utility model content
Technical problem to be solved in the utility model is directed to above-mentioned prior art and provides a kind of steel wire mesh frame shaping
Special-shaped support mandrel, the corresponding steel wire mesh frame for obtaining of the special-shaped support mandrel is cylindrical, circumferential welding seam, edge
Steel wire mesh frame circumference performance is uniform.
The utility model corresponds to the support frame of the steel wire mesh frame primarily as plastic tube of acquisition, including along plastic tube
The supporting steel wire layer that length direction extends, and the winding steel wire layer being spirally wound on the supporting steel wire layer, it is preferable that winding
The mid-wrap steel wire floor and backpitch that steel wire floor is wrapped on supporting steel wire layer including right-handed screw again are wrapped in the centre
Outer layer winding steel wire layer on winding steel wire layer.Adjacent wires layer at least layer of steel wire layer steel wire on be coated with hot melt skin
To make to be bonded by way of heat fusion joint is contacted between adjacent wires layer.
The technical scheme in the invention for solving the above technical problem is：A kind of steel wire mesh frame shaping special-shaped support
Mandrel, including support axis body, the lead phase of the bearing of trend of the support axis body and the supporting steel wire layer of steel wire mesh frame
Unanimously, some half grooves for axially extending uniformly are offered on the outer peripheral face of the support axis body, if constituting supporting steel wire layer
Dry steel wire is corresponded and is embedded in half groove, and in the presence of tractive force, supporting steel wire layer can be along half groove to reach
It is dynamic；Further, it is shaped to stripe-shape plane between adjacent half groove to meet the centre being spirally wound on supporting steel wire layer
Winding steel wire layer remains discontiguous state with support axis body.
Preferably, half groove is deep-slotted chip breaker, and the steel wire adaptability with supporting steel wire layer coordinates, it is to avoid steel wire was drawing
Slipped from deep-slotted chip breaker in journey.
Further, the number of half groove is consistent with the number of the parallel steel wire of supporting steel wire layer.
The operation principle of above-mentioned special-shaped support mandrel is, for supporting steel wire layer provides support force, the ring of supporting steel wire layer
The steel wire be arrangeding in parallel is corresponded and is embedded in half groove on support mandrel surface, makes supporting steel wire layer in the process to front haulage
In be not scattered；Simultaneously during traction, then mid-wrap steel wire floor is constituted in supporting steel wire layer external spiral winding steel wire, be
Ensure that mid-wrap steel wire floor does not influence supporting steel wire layer normal to front haulage, need to avoid mid-wrap steel wire floor all the time not with
Support axis body contact.Usually, the outer successively spiral winding of supporting steel wire layer has two-layer winding steel wire layer, two-layer winding steel wire layer point
Other right-handed screw or backpitch are wound, and the continuously shaped of welding steel wire mesh frame can be realized by above-mentioned special-shaped support mandrel,
Ensure steel wire mesh frame ring performance uniformity.
Compared with prior art, the utility model has the advantage of：It is steel wire bone there is provided a kind of special-shaped support mandrel
The supporting steel wire layer of frame innermost layer is provided a supporting role, and supporting steel wire layer is during to front haulage again successively on spiral winding
Winding steel wire layer, is the offer support of working continuously of steel wire mesh frame shaping.
Brief description of the drawings
Fig. 1 is the lateral arrangement figure of special-shaped support mandrel in the utility model embodiment；
Fig. 2 is the AA schematic cross-sections of special-shaped support mandrel shown in Fig. 1.
