Detailed description of the invention

In order to clearly describe this utility model, new to this practicality with detailed description of the invention below in conjunction with the accompanying drawings Type is described in further detail.

Embodiment 1

A kind of coil winding shaping mould, drives the body carrier 2 rotated and is fixed on this body carrier 2 including rotating shaft 5 On tube head positioning fixture 3.See Fig. 1 and Fig. 3.

Body carrier 2 includes tubular plate 22 and lays respectively at its opening two adjacent side plates 21 normal thereto, side plate 21 ends and tubular plate 22 on its inside constitute indent cell body 25；Connected by the first bolt 23 between side plate 21, first Bolt 23 is eight, and circular array is arranged at equal intervals, sees Fig. 4, and this first bolt array is positioned at tubular plate 22, the first bolt The screw rod of 23 is close to tubular plate 22 inwall so that this bolt array and tubular plate 22 interference fit, tubular plate 22 can be with this spiral shell Bolt array rotation.Tubular plate 22 is played skeletal support effect by the first bolt 23 array, keeps tubular plate 22 dimensionally stable, prevents Compressive deformation causes coil pipe body gap uneven.

The outer wall of tubular plate 22 is provided with the arc raceway groove 223 of spiral distribution, sees Fig. 1 and Fig. 2, the arcwall face of raceway groove half Footpath be slightly larger than outer tube diameter, be used for carrying body, the Spiral distribution of raceway groove level off to coil pipe inner spiral layer body distribution.Multilamellar First dish internal layer during the coil pipe dish of helical structure, remainder layer stacks along internal layer body, the therefore dish quality of internal layer body To coil pipe is the most qualified, there is material impact.The arc raceway groove 223 of spiral distribution makes the internal layer body location distribution of coil pipe, The quality of coil pipe profile can be significantly improved, improve qualification rate.Arc raceway groove 223 is big with body contact area simultaneously, it is possible to have Effect avoids body stress raisers to cause deformation.

The circumferential ends of side plate 21 to being externally provided with multiple extension 211 spaced apart, is shown in Fig. 3 along side plate 21 direction, uses In the space of increase cell body 25, reduce the quality of side plate 21 simultaneously.

As preferably, tubular plate 22 is connected and composed by two curved panel head and the tail.Curved panel end is provided with to varus Connecting plate 221, the junction of lower arcuate panel, connected by the second bolt 222 between adjacent connection plates 221.Lower arcuate The adjacent connection plates 221 of panel is set to be parallel to each other, it is simple to assemble.By regulating the degree of tightness of the second bolt 222, it is possible to convenient Realize the first bolt 23 array and tubular plate 22 interference fit.

Side plate 21 centre is provided with the axle sleeve 1 running through it, rotating shaft 5 and axle sleeve 1 and is connected, and rotating shaft 5 rotates and drives pipe Body carrier 2 rotates.As preferably, axle sleeve 1 and rotating shaft 5 being equipped with pin-and-hole, rotating shaft 5 passes through bearing pin 11 and axle sleeve 1 through axle sleeve 1 Realization removably connects.Bearing pin 11 connects can be dismantled very easily, simultaneously facilitates the processing and manufacturing of mould.

The side plate 21 that body carrier 2 assembles curved panel and band sleeve by bolt is constituted, and curved panel and side plate 21 can To design plurality of specifications according to diameter, arc raceway groove 223 size etc., select voluntarily during use to assemble.Meet plurality of specifications The processing of coil pipe needs.Coil pipe completion of processing, unclamps bolt, can take off coil pipe easily, significantly alleviate personnel labor intensity, Improve working performance.

Tube head positioning fixture 3 includes body 31 and mobile 32, uses narrow iron bar to make, and the lower weld of body 31 is fixed On side side plate 21, top and the mobile 32 of body 31 are equipped with segmental arc, and two segmental arcs constitute clamping part 33, clamping part 33 are positioned at above cell body 25 near body 31 side side plate 21；Body 31 and mobile 32 lead to above and below segmental arc respectively Crossing two the 3rd bolts 34 to connect, the nut location of regulation the 3rd bolt 34 side, in order to adjust the space size of clamping part 33. Tube head stretches into clamping part 33, time fixing, with spanner by nut screwing clamping.

Further improvement to the technical program, body carrier 2 is provided with fixture on side plate 21 outer wall, and fixture is two sides Being arranged symmetrically with in pairs on plate 21, fixture is for fixing one end of binding strap 4, and binding strap 4 can be fixed on cell body 25 by paired fixture On.Coil pipe completion of processing, needs to tighten fixing with binding strap 4, owing to coil pipe weight is more than tens kilograms, single cannot move Dynamic, cause the fixing inconvenience of binding strap 4.Binding strap 4 is typically chosen plastic material, has elasticity, is fixed in card before coil pipe On tool, do not affect coil pipe operation, treat that coil pipe is complete, colligation can be carried out on body carrier 2, very convenient laborsaving.As excellent Choosing, fixture is otic placode 24, as long as with holes, by binding strap 4 through both sides side plate 21 upper ear plate 24 hole, becomes arcuation, and utilization is tied up The elastic stress of band 4 can be fixed.

In this explanation, the first bolt, the second bolt, the 3rd bolt are only used for distinguishing in this utility model mould not coordination Put the bolt with function or bolt combination, in order to illustrate and understand technical solutions of the utility model, do not limit the first bolt, Second bolt, the quantity of the 3rd bolt or structure, the general significance that should make bolt understands.

To sum up, application the present embodiment is in the processing of the copper coil pipe of multi layer spiral structure, it is possible to makes coil pipe density uniform, keeps away Exempt from body extrusion, it is ensured that coil pipe quality, improve efficiency and the qualification rate of coil pipe processing, reduce personnel labor intensity.

Above this utility model is described in detail, this utility model is applied specific case to of the present utility model Embodiment is set forth, and the explanation of above example is only intended to help and understands this utility model, it is noted that for this For those skilled in the art, on the premise of without departing from this utility model principle, if also this utility model can be carried out Dry improvement, these improvement also fall in this utility model scope of the claims.
