Description

The spring line curvature control structure of spring forming machine

Technical field

The utility model relates to the structure that a kind of spring is produced facility, refers to a kind of spring line curvature control structure of spring forming machine especially, so that spring can produce in full automatic mode.

Background technology

Spring is the flexible member that a kind of quilt extensively applies to mechanical field, modal is exactly helical spring, yet along with user demand with the assembling implement structure different, the moulding of spring also can be different, for example: extension spring, torsion spring, volute spring ... or the like, wherein special with the moulding of torsion spring again.

And these have special formed torsion spring, often all need during fabrication just can finish through processing repeatedly, sometimes even must increase manual processing procedure, can produce the special torsion spring of moulding, or must in response to manufacture process each～two steps just are provided with a base platform, not only make outside the manufacturing cost raising, also reduced production efficiency.

In view of this, utility model designer is a spring line curvature control structure of designing a kind of spring forming machine, so that the production that torsion spring can be changed fast and automatically, and make the torsion spring can one-shot forming and exempt manual processing procedure, perhaps can exempt in manufacture process, the semi-finished product of torsion spring being passed to the problem that another board processing just can be made.

Summary of the invention

Main purpose of the present utility model is that a kind of spring line curvature control structure of spring forming machine is being provided, so that the circle of torsion spring can one-shot forming around section, linear section, being beneficial to torsion spring can produce in the mode of automation.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of spring line curvature control structure of spring forming machine is erected on the board of spring forming machine, and corresponding with the outlet port of spring line, it is characterized in that, comprises at least:

Bent once rule assembly has following bent rule that are arranged on outlet port periphery, and sets up with the lower slider, that limits its helical pitch direction for bent rule down and be located in the lower slider so that bent down rule remain on the following elastic reset member of reference position, described bent down rule rear end connects one and can carry out linear lower skateboard toward polyslip with respect to lower slider;

Bent rule assembly on one has one and is arranged on the bent rule of going up of outlet port periphery, and keeps supplying bent rule and set up to be located in the upper saddle so that go up last elastic reset member, the described bent rule rear end of that bent rule remain on the reference position with the upper saddle, that limits its displacement helical pitch and connect a upper slide that can carry out linear past polyslip with respect to upper saddle;

One first crank arm assembly is with bent rule assembly connection down;

One second crank arm assembly connects with last bent rule assembly;

One labyrinth controller is with bent rule assembly and one of them connection of upward bent rule assembly down, to drive lower skateboard and one of them displacement of upper slide;

One driving shaft connects aforementioned first crank arm assembly, second crank arm assembly and labyrinth controller; And

One motor connects aforementioned driving shaft.

Another concrete enforcement of the utility model, be with described first crank arm assembly, design comprises: one be located at first cam, on the driving shaft be pivoted an end on the board contact at first of first cam crank arm, one be connected in first crank arm and bent down rule assembly between first connecting rod, first cam has one first section poor protuberance.

The utility model is a concrete enforcement again, be with described second crank arm assembly, design comprises: one be located at second cam, on the driving shaft be pivoted an end on the board contact at second of second cam crank arm, one be connected in second crank arm and last bent rule assembly between second connecting rod, second cam has one second section poor protuberance.

The another concrete enforcement of the utility model, be that design comprises with described labyrinth controller: one be located at the 3rd cam, on the driving shaft be pivoted an end on the board contact at the 3rd of the 3rd cam crank arm, one be located at the 3rd crank arm with the bent down rule assembly of ejection with last bent advise assembly one of them push away bolt; Aforementioned the 3rd cam has a gradual protuberance, pushes away bolt and be can promote to be arranged on down bent rule assembly or go up lower skateboard, upper slide on the bent rule assembly, and being respectively arranged with one on aforementioned lower skateboard, the upper slide can the supporting member corresponding with pushing away bolt, for pushing away the usefulness that bolt is replaced.

During aforementioned drive shaft turns, can drive first crank arm assembly, second crank arm assembly and labyrinth controller according to the sequential start, first crank arm assembly, second crank arm assembly just in due course machine drive bent down rule assembly, go up bent rule assembly lateral displacement, make down bent rule, go up bent the rule and detach line cap; And this simultaneously, and the labyrinth controller can drive bent rule assembly again and carry out reciprocal asymptotic displacement with respect to bent rule assembly down, makes down bent rule, goes up asymptotic, the gradually variation far away of bent relative distance generation of advising.

During enforcement, visual user demand, following bent rule assembly or among the bent rule assembly, select one and bent down rule be installed or go up bent rule, upper and lower bent rule select a purpose of installing, be to produce the torsion springs of different circles around direction.

Instantly bent rule, go up bent rule and be positioned at the outlet port, and the outlet port is when continuing outlet, the spring line promptly can collide down bent rule, can form circle around section after going up bent the rule; Drive bent down rule assembly, go up bent rule assembly when first crank arm assembly, second crank arm assembly again, the bent down rule of order, go up that bent rule detach line cap and outlet port when continuing outlet, can make the linear section moulding of torsion spring; And song is advised instantly, upward bent rule are positioned at the outlet port, and the labyrinth controller drives bent rule assembly and carries out reciprocal asymptotic displacement with respect to bent rule assembly down, and make down bent rule, the relative distance that goes up bent rule produce asymptotic, gradually during variation far away, circle just can produce the molding effect of labyrinth gradual change around section, to present the aspect of coniform spiral moulding.

In other words, as long as the operator can carry out suitable control, allotment to the start sequential of first crank arm assembly, second crank arm assembly and labyrinth controller, can produce and have the torsion spring of circle, even also can make circle present the aspect of coniform spiral moulding around section around section, linear section.

Compared to prior art, the utility model can make the circle of torsion spring around section, the one-shot forming of linear section energy, be beneficial to the production that torsion spring can be changed fast and automatically, and make the torsion spring can one-shot forming and exempt manual processing procedure, perhaps can exempt in manufacture process the problem that must the favourable turn platform just can process once more.
