Abstract
The invention discloses a square-section leading-in structure of a spring coiling machine. The square-section leading-in structure comprises a support and a core cutter, wherein the support is detachably fixed on the frame of the spring coiling machine; a flat cutting surface is arranged on one side of the core cutter; a circular arc-shaped spring coiling surface is arranged on the other side of the core cutter; a fixing groove is formed in the support in the length direction of the support; the circular arc-shaped spring coiling surface of the core cutter is fixed in the fixing groove of the support in a close fit way; one end of the core cutter extends out of the fixing groove. Through the adoption of the structure, a split-type coiling and cutting die is formed, so that the support can be made of a cheaper material. Besides, when the core cutter is abraded by impact, a user only needs to replace the core cutter or cut off the abraded part of the core cutter and does not need to replace the support, so that the maintenance cost of equipment is greatly reduced. In addition, the core cutter and the support are simple in structure and very convenient to assemble.
Description
Technical field
The present invention relates to spring coiling machine, particularly relate to the Separated type spring winding on spring coiling machine and cutting mould.
Background technology
Spring coiling machine adopts wire feed rolls to send steel, after spring has rolled, needs steel to cut off to roll next spring on winding and cutting mould.Existing winding and cutting mould as shown in Figure 1 or 2, generally comprise bearing 01 and core cutter 02, and core cutter 02 and bearing 01 are integral type structure, and core cutter 02 side is the roll setting face 021 matched with cutoff tool, and core cutter opposite side is circular arc spring wind face 022.When the spring completed around the home need cut off, winding and cutting mould motionless, cutoff tool impacts downwards, utilize shearing force cut-out steel.Repeatedly cutting off in the process of spring steel wire, core cutter will bear repeated cutting impulsive force load, 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 a kind of structure simple, Separated type spring winding on the spring coiling machine of maintenance cost and cutting mould can be reduced.
For achieving the above object, the present invention is by the following technical solutions:
Separated type spring winding on spring coiling machine and cutting mould, it comprises bearing and core cutter, described bearing is detachably fixed in the frame of spring coiling machine, 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, and 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.
The shape in described holddown groove and core cutter circular arc spring wind face is suitable.
The present invention adopts above technical scheme, makes split type by winding and cutting mould, and thus, bearing can with selecting cheaper material manufacture.Secondly, when core cutter is hit and weares and teares, only core cutter can be carried out the position replacing or cut the wearing and tearing of core cutter, and without the need to replacing time, therefore, greatly reduce maintenance cost and the material cost of equipment.In addition, core cutter of the present invention and seat structure simply, are assembled very convenient.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details:
Fig. 1 is the structural representation of winding and cutting mould on spring coiling machine in prior art;
Fig. 2 is the schematic diagram that in prior art, cutoff tool cuts off spring;
Fig. 3 is Separated type spring winding on spring coiling machine of the present invention and the structural representation of cutting mould.
Detailed description of the invention
As shown in Figure 3, the present invention includes bearing 1 and core cutter 2, described bearing 1 is detachably fixed in the frame of spring coiling machine, the side of described core cutter 2 is smooth roll setting face 21, opposite side is circular arc spring wind face 22, described bearing 1 is provided with holddown groove 11 along its length, and the side in described core cutter 2 circular arc spring wind face 22 is by being tightly fixed in the holddown groove 11 of bearing 1, and holddown groove 11 is extended in one end of core cutter 2.
Described holddown groove 11 is suitable with the shape in core cutter 2 circular arc spring wind face 22.
Adopt above design, make split type by winding and cutting mould, thus, bearing 1 can with selecting cheaper material manufacture.Secondly, when core cutter 2 is hit and weares and teares, only core cutter 2 can be replaced, if core cutter 2 long enough, the position of wearing and tearing is cut, and the holddown groove 11 of core cutter 2 along bearing 1 is knocked forward, make the unworn position of core cutter 2 extend the holddown groove 11 of bearing 1, and without the need to replacing time 1, thus greatly reduce cost of equipment maintenance and material cost.In addition, bearing 1 of the present invention adopts holddown groove 11 to carry out mounting core cutter 2, and structure is simple, and easy to assembly.
Claims (2)
1. the Separated type spring winding on spring coiling machine and cutting mould, it is characterized in that: it comprises bearing and core cutter, described bearing is detachably fixed in the frame of spring coiling machine, 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, and 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.
2. the Separated type spring winding on spring coiling machine according to claim 1 and cutting mould, is characterized in that: the shape in described holddown groove and core cutter circular arc spring wind face is suitable.
