Technical field
The present invention relates to field of spring processing, particularly relate to Rectangular Section Spring machine-shaping module.
Background technology
Along with the development of technology, the spring of square-section is more and more to be used, automatic spring winding machine also starts carrying out square-section wind spring shaping around the home step by step, automatic spring winding machine generally comprises feed mechanism, winding core bar assembly, cutting mechanism, pitch-changing mechanism and bending mechanism, the shaping process of spring wind is: under the drive of feeding roller group, square-section wind spring after a guided way, around winding core bar assembly coiling and molding under the effect of bending mechanism.As shown in Figure 1, existing guided way generally comprises the rectangle support 01 of a strip, the directed cavity 011 allowing Rectangular Section Spring pass is provided with in this support 01, after Rectangular Section Spring passes the directed cavity of above-mentioned guided way 011, coiling and molding is carried out again around winding core bar assembly, in order to obtain the pitch of spring, Rectangular Section Spring can produce the trend of trickle rotation in forming process around the home in directed cavity, and support is fixed in frame, the rotation of the directed cavity of rectangle restraining spring again, therefore, the phenomenon that Rectangular Section Spring was importing and can produce in process around the home card and pauses, thus affect wind spring quality.
In addition, as shown in Figure 2 or Figure 3, existing winding core bar assembly 02 generally comprises bearing 021 and core cutter 022, and core cutter 022 and bearing 021 are integral type structure, core cutter 022 side is the roll setting face matched with cutoff tool, and core cutter 022 opposite side is circular arc spring wind face.When the spring that completes around the home cuts off, winding and cutting mould motionless, cutoff tool 03 impacts downwards, utilizes shearing force cut-out steel.Repeatedly cutting off in the process of spring steel wire, core cutter will bear the cut-out impulsive force load of repetition, under the effect of long-term impact varying load, core cutter can produce wearing and tearing or crackle tendency unavoidably, if core cutter produces wearing and tearing, then to reprocess, if the tendency of cracking, then finally unexpected brittle fracture can occur.Because winding and cutting mould are integral structures, and the strength of materials higher grade that core cutter is generally selected, and therefore, virtually adds material cost, and when core cutter is scrapped, related bearing also will be scrapped, and virtually adds the maintenance cost of equipment.
Summary of the invention
In order to solve deficiency of the prior art, the object of the present invention is to provide the Rectangular Section Spring machine-shaping module that a kind of production efficiency is high, maintenance cost is low.
For achieving the above object, the present invention is by the following technical solutions:
Rectangular Section Spring machine-shaping module, comprise frame and be located at the feed mechanism in frame, winding core bar assembly, cutting mechanism, pitch-changing mechanism and at least Liang Tao bending mechanism, winding core bar assembly is located at the output of feed mechanism, bending mechanism, cutting mechanism and pitch-changing mechanism circumferentially order are distributed in the periphery of winding core bar assembly, described feed mechanism comprises feeding roller group and guided way, guided way is located at the output of feeding roller group, described guided way comprises support, described internal stent along its length turning set is provided with circular sleeve, described circular sleeve is provided with the rectangle directed cavity running through its two ends along its axis, the raw material of described Rectangular Section Spring after the guiding of rectangle directed cavity around winding core bar assembly coiling and molding,
Described winding core bar assembly comprises bearing and core cutter, the side of described core cutter is smooth roll setting face, opposite side is circular arc spring wind face, described bearing is provided with holddown groove along its length, the side in described core cutter circular arc spring wind face is by being tightly fixed in the holddown groove of bearing, and holddown groove is extended in one end of core cutter.
Described bending mechanism comprises the slide unit be fixed in frame, bending tool rest and bending cutter head, and described bending tool rest is located on slide unit, and is slided on slide unit by driving mechanism drive; Described bending cutter head is fixed on bending tool rest by clamping screw, and extends one end of slide unit; One end of described bending tool rest is provided with the strip groove perpendicular to bending tool rest glide direction, and described clamping screw is located in strip groove.
The bending edge of a knife of described bending cutter head is made up of the side of end face and arc.
The present invention adopts above technical scheme, has the following advantages:
1, guided way is the structure that inside has rotatable circular sleeve, the rotatory force that Rectangular Section Spring produces in the process of coiling and molding can drive circular sleeve to rotate, thus the generation that minimizing vibrations and card pause, improve the smoothness of spring wind, and then the quality that raising Rectangular Spring is produced.
2, make split type by the bearing in winding core bar assembly and core cutter, thus, bearing can with selecting cheaper material manufacture.Secondly, when core cutter is hit and weares and teares, only core cutter can be replaced, and without the need to replacing time, therefore, greatly reduce the maintenance cost of equipment.
3, in bending mechanism, bending cutter head and bending tool rest are made split type, when bending cutter head is because of fatigue wear, can change bending cutter head separately, the maintenance of equipment that senior general is low and the cost of maintenance.In addition, the strip groove that bending tool rest one end has, and clamping screw is arranged in strip groove and leads, realize bending cutter head perpendicular to the position adjustments in bending tool rest glide direction, therefore bending cutter head regulates more flexible, and the wind spring work of spring is more accurately good.
