Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-6 is please referred to, the utility model provides a kind of molding machine of stable inside and outside circle of aluminum steel coiling, including molding Seat 1, mandrel 2 and auxiliary lid 3, the inside of molding seat 1 is fixed with three bearings 4, the uniform mandrel 2 one of the inner wall of three bearings 4 The outer wall at end is fixedly connected, and the other end of mandrel 2 passes through the outside that molding seat 1 is placed in 1 side of molding seat, the top of molding seat 1 It symmetrically opens up there are two the first bolt hole 5, the top of auxiliary lid 3 is symmetrically opened up there are two the second bolt hole 6, and auxiliary lid 3 passes through Bolt 8 passes through corresponding first bolt hole 5 and the second bolt hole 6 is fixedly connected with the top of molding seat 1.

Preferably, the bottom end of molding seat 1 is symmetrically opened up there are two third bolt hole 7, is easily installed molding seat 1.

Preferably, the sectional dimension of 2 one end of mandrel is greater than the sectional dimension of the other end, and the assembly for being conducive to mandrel 2 uses, Prevent mandrel 2 is undersized to be not easy to install.

Preferably, auxiliary lid 3 is L-type auxiliary lid, makes to assist lid 3 that molding seat 1 is preferably cooperated to use.

Preferably, the bottom end of lid 3 is assisted to offer arc groove 9, and the position of the position of arc groove 9 and 2 other end of mandrel It is corresponding, auxiliary is played the role of by arc groove 9, is conducive to the coiling of aluminum steel.

When specifically used, the molding machine of inside and outside circle is stablized in a kind of aluminum steel coiling of the utility model, first by passing through the Molding seat 1 is mounted on suitable position by three bolts hole 7, then carries out coiling to aluminum steel, in winding process, since mandrel 2 passes through Bearing 4 is fixed on molding seat 1, rotate mandrel 2 can in process, then can effectively reduce frictional resistance, Wire rod in spring coiling process is avoided to glue knife；Simultaneously as mandrel 2 be rotation, can to avoid mandrel 2 same point always with The contact of wire rod, to effectively radiate, adsorb residue because of fever during avoiding aluminum steel from rolling causes on mandrel 2 Outer diameter is unstable, avoids causing spring sizes unstable because heat is excessive in aluminium material spring coiling process, and winding process In can be by assisting lid 3 play the role of auxiliary, since auxiliary lid 3 be fixedly connected by bolt 8 with molding seat 1, then just In the installation and removal of auxiliary lid 3, it is conveniently replaceable after auxiliary lid 3 damages.
