Description

The automatic rotating winding mechanism in a kind of spring wire termination

Technology contents:

The present invention relates to compress the technical field of spring production machine tool, specifically be meant a kind ofly can make the automatic rotating winding mechanism in spring wire termination.

Background technology:

Compression spring production machine tool (pressure spring machine) is a kind of processing machine that can make the spring wire coiling and molding.Line as its employed spring wire directly is no more than 5mm, need not special winding mechanism and also can produce; But for wire rod line footpath greater than for the spring goods of 5mm, be generally the big line footpath wire rod of 5mm-20mm, usually need the operative employee to use the manual mode of coiling utensil personnel selection power to be wound into circular-arc or repeatable operation hydraulic cylinder or motor promotion slide block drive curve gauge seat and curve gauge, be pressed into the wire rod of rectilinear form circular-arc, again wire rod is placed in the wire casing of two curve gauges, could debug or produce the compression spring, waste time and energy, influence production efficiency greatly, the coiling function of big line diameter spring reduced the competitiveness of self, so certainly will become the indispensable function that big line directly compresses the spring production machine tool.Known in the market winding mechanism mainly contains two kinds:

Mechanism one is Wound-rotor type manually, as shown in Figures 1 to 3, comprise wire rod 5, Wire Wheel 6 and preceding wire guide plate 8, Wire Wheel 6 is sent wire rod 5 through preceding wire guide plate 8, wire rod 5 is penetrated in the hole of coiling handle 13 ends the artificial coiling handle 13 that rotates again by operating personnel, make wire rod 5 be wound into circular-arc after, wire rod 5 is placed in the wire casing of two curve gauges 9, curve gauge 9 is placed on the curve gauge seat 12 again, is regulated by slide block 10.This method operation easier is big, and production efficiency is low, is difficult for promoting.

Mechanism two is mechanical Wound-rotor type, as shown in Figs. 4-6, comprise wire rod 5, Wire Wheel 6, preceding wire guide plate 8, Wire Wheel 6 with wire rod 5 after preceding wire guide plate 8 is sent, actuating unit 11 (hydraulic cylinder or motor) action, promote slide block 10, the curve gauge 9 on the curve gauge seat 12 acts on the wire rod 5, make wire rod 5 be pressed into circular-arc after, again wire rod 5 is placed in the wire casing of two curve gauges 9, this method complex structure, troublesome poeration, cost is higher not to have efficient.

Summary of the invention:

The objective of the invention is to overcome deficiency of the prior art, can make the automatic rotating winding mechanism in spring wire termination and provide a kind of.

The present invention is achieved through the following technical solutions, and comprises somely to being built up in the Wire Wheel on the body side by side, and the both forward and reverse directions rotation respectively of Wire Wheel that symmetry is set up mouthful is moved to sending through preceding wire guide plate to promote wire rod.On the body of sending mouthful the place ahead of wire rod, also set up winding mechanism, described winding mechanism comprises can be by the roll of power driven rotary, bobbin winder base is fixed on the roll, bearing pin off-centre is installed on the bobbin winder base, the external diameter distance of described bearing pin and roll is slightly larger than the diameter of wire rod, and the wire rod leading-out terminal stretches between roll and the bearing pin.

The present invention can make the compression coiling machine in debugging or produce spring, and when changing big line footpath wire rod, become simple, easily, efficient, cheap, the suitable popularization.

The specific embodiment:

Shown in Fig. 7 to 11, the present invention includes somely to being built up in the Wire Wheel 6 on the body side by side, Wire Wheel that symmetry is set up 6 both forward and reverse directions rotation respectively mouthful is moved to sending through preceding wire guide plate 8 to promote wire rod 5.On the body of sending mouthful the place ahead of wire rod 5, also set up winding mechanism, described winding mechanism comprises can be by the roll 3 of power driven rotary, bobbin winder base 4 is fixed on the roll 3, bearing pin 7 off-centre are installed on the bobbin winder base 4, the external diameter distance of described bearing pin 7 and roll 3 is slightly larger than the diameter of wire rod 5, and wire rod 5 leading-out terminals stretch between roll 3 and the bearing pin 7.

During work because bearing pin 7 and the external diameter distance of roll 3 are slightly larger than the diameter of wire rod 5, so Wire Wheel 6 with wire rod 5 after preceding wire guide plate 8 is sent, wire rod 5 enters between roll 3 and the bearing pin 7, the demand of the enough circular arc distortion of the length that wire rod 5 is entered.The dynamical system of being made up of motor 1 and reductor 2 drives roll 3 rotations, bobbin winder base 4 is followed roll 3 and is together rotated, promptly make the eccentric bearing pin of installing 7 around the rotation of the center of roll 3, bearing pin 7 and the roll 3 common wire rods 5 that pin, the termination that makes wire rod 5 produces the circular arc distortion together around the rotation of the center of roll 3.After roll 3 turns to desired location, Wire Wheel 6 line sendings, make wire rod 5 continue to move forward, no longer by roll 3 and bearing pin 7 lockings, after wire rod 5 broke away from bobbin winder base 4, Wire Wheel 6 moved back line to wire rod 5, wire rod 5 is placed in the wire casing of two curve gauges 9, curve gauge 9 is placed on the curve gauge seat 12, is regulated by slide block 10, finishes the coiling step of termination.
