Abstract
A steel wire shearing-off unit of full-automatic spring coiling machine is composed of fixed cutter and its fixer, movable cutter fixed to the arbor unit consisting of cutting arbor, restoring spring and ejecting rod, swinging arm and its supporter, contact wheel and cam driven part.
Description
Technical field:
The present invention relates to field of spring processing, be specifically related to a kind of steel wire shearing device of full automatic spring coiling machine.
Background technology:
Traditional steel wire shearing device is close to the wire straightening hole exits, utilizes fixedly steel wire of wire straightening hole, and hilted broadsword cuts off then, easily makes steel wire and wire straightening bore deformation, and the wire straightening hole exits easily stops up, and influences spring-mass.
Summary of the invention:
The steel wire shearing device that the purpose of this invention is to provide a kind of full automatic spring coiling machine accurately and efficiently.
For reaching above-mentioned purpose, technical solution of the present invention is: include fixed cutting tool, moving cutting tool, knife bar device, swing arm, swing arm support, cam, cam follower, holder, support, cam is provided with the 3rd and regulates elongated slot, holder is fixed on the support, copper sheathing and spline housing are housed in the holder, and fixed cutting tool is fixed in the holder, is provided with second elongated slot in the fixed cutting tool, moving cutting tool is fixed on the knife bar device, is provided with the 3rd elongated slot in the moving cutting tool; The knife bar device is made up of cut-out knife bar, back-moving spring, push rod, and the knife bar device can slide in holder, and back-moving spring is sleeved on the cutoff tool bar, and push rod is fixed on and cuts off knife bar one end, and moving cutting tool is fixed on and cuts off the knife bar other end; The swing arm support is fixed on the support, and swing arm is installed on the fixed axis of swing arm support, and the swing arm upper end is fixed with bumps wheel, and the lower end is fixed with cam follower.
The present invention adopts said structure, after steel wire comes out from form wheel, shear disconnected by interlacing before and after fixed cutting tool and the moving cutting tool, the steel wire distortion is little, and the steel wire shearing device has certain distance from the wire straightening hole exits, during steel wire shearing to the wire straightening hole exits without any influence, guaranteed spring-mass.
Description of drawings:
Fig. 1, cutaway view of the present invention;
Fig. 2, dorsal surface schematic perspective view of the present invention;
Fig. 3, the positive side of the present invention schematic perspective view.
The specific embodiment:
As shown in Figure 1, a kind of steel wire shearing device of full automatic spring coiling machine, comprise fixed cutting tool 1, moving cutting tool 2, knife bar device 3, swing arm 4, swing arm support 5, cam 6, cam follower 7, holder 8, support 9, cam is provided with position the 3rd and regulates elongated slot 10.
Shown in Fig. 1,3, holder 8 is fixed on the support 9, and copper sheathing 11 and spline housing 12 are housed in the holder 8.Fixed cutting tool 1 is fixed in the holder 8, be provided with first elongated slot 13 that is used for regulating in the fixed cutting tool 1, moving cutting tool 2 is fixed on the knife bar device 3, is provided with second elongated slot 14 that is used for regulating in the moving cutting tool 2, and fixed cutting tool 1 and moving cutting tool 2 blades are carbide alloy.
As shown in Figure 1, knife bar device 3 is formed by cutting off knife bar 15, back-moving spring 16, push rod 17 etc., and knife bar device 3 can slidably reciprocate in holder 8.Back-moving spring 16 is sleeved on and cuts off on the knife bar 15, between holder 8 and push rod 17.Push rod 17 is fixed on and cuts off knife bar 15 1 ends, and moving cutting tool 2 is fixed on and cuts off knife bar 15 other ends.
As shown in Figure 2, swing arm support 5 is fixed on the support 9, and swing arm 4 is installed on the fixed axis of swing arm support 5, can rotate around fixed axis.The swing arm upper end is fixed with bumps wheel 18, and the lower end is fixed with cam follower 7.
Operation principle: referring to implementing legend, cam 6 rotates, projection on the cam 6 contacts with cam follower 7 in the swing arm 4, force swing arm 4 to be swung around the fixed axis clockwise, 18 push rods 17 that touch in the knife bar device 3 are taken turns in bumping of swing arm upper end, force knife bar device 3 being with moving cutting tool 2 in holder 8 slides forwards, and fixed cutting tool 1 is motionless, moving cutting tool 2 promotes forward, and two cutting knifes interlace and cut off steel wire.When cam 6 turns to projection when leaving cam follower 7, back-moving spring 16 in the knife bar device 3 forces push rod 17 being with cut-out knife bar 15 and moving cutting tool 2 to move backward, moving cutting tool 2 resets, and push rod 17 promotes the swing of swing arm 4 inverse clocks by bumping wheel 18, forces swing arm 4 to reset.When cam 6 turns to projection when contacting with cam follower 7, begin steel wire shearing next time again.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
