Description

The young chain of box is knitted the chain machine

Technical field

The utility model relates to the chain machine of knitting that a kind of jewel manufacturing industry is used, and is used to process building block box shape and pearl necklace or bangle.

Background technology

The common chain machine of knitting that is used to process building block box shape and pearl necklace in the prior art, general cut-out with material, bending forming separately carries out, then on press machine, to finish clasp or chaining by hand, have that work efficiency is low, industrial injury greatly, easily takes place labour intensity, because of closing up a mouthful size, ring is difficult to control simultaneously, defectives such as welding difficulty, percent defective height.

Summary of the invention

The purpose of this utility model provides a kind of chain machine of knitting, and compared with prior art, this knits the chain facility has automaticity height, ring to close up mouthful size accurately to control, advantage such as technology is simple, percent defective is low.

The technical solution of the utility model is: this knits the chain machine, comprises feed mechanism, cutoff tool, spring, die, can 180 ° of transposition gripping mechanisms, scalable core rods be punch, detent rail, clamp mould; Described feed mechanism be installed in can 180 ° of transposition gripping mechanisms the left side, described die comprises that cutoff tool is installed in the top of gripping mechanism, described scalable core rod is that the punch level is installed in jaw the place ahead and vertical with the die cavity of clamp mould; Described end that can 180 ° of transposition gripping mechanisms is equipped with clamp, described clamp is installed on the clamp box, be connected with extension spring between the clamp box, the lower end of clamp box contacts with the rod end conical surface of follower lever, but described clamp box is installed on the toothed rotary table face by two straight pins; Described scalable core rod is that punch contains big punch and small punch, and big punch and small punch are installed in the core rod box, clamp by location cassette holder and clamping plate, and be provided with can protract or after the slide rail and the riser guide that contract.

The chain machine of knitting that uses the utility model to provide, because this is knitted the chain machine and structurally is provided with parts such as feed mechanism, clamp and shearing device, scalable core rod, all realize automation from feeding, blank, loop forming to the whole process of chaining, therefore compared with prior art, this knits the chain facility has automaticity height, ring to close up mouthful size accurately to control, advantage such as technology is simple, percent defective is low.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further explained.

In Fig. 1 as can be seen, this knits the chain machine, comprise feed mechanism 1, cutoff tool 2, spring 3, die 4, can 180 ° of transposition gripping mechanisms 5, scalable core rods be punch 6, detent rail 7, clamp mould 8, described feed mechanism 1 be installed in can 180 ° of transposition gripping mechanisms 5 the left side, described die 4 comprises that cutoff tool 2 is installed in the top of gripping mechanism 5, and described scalable core rod is that punch 6 levels are installed in jaw the place ahead and vertical with the die cavity of clamp mould 8.

Fig. 2 is can 180 ° of transposition gripping mechanism schematic diagrames.But in fact this gripping mechanism 5 is exactly the rotary table of energy automated exchanged cutter in the multistation processing, also claims rotary jig; In the chain process, gripping mechanism 5 also plays the effect of shaping and correction, closes up the quality of mouth and the fineness of profile to guarantee ring, so play the effect of removable die again.As figure, the end of this gripping mechanism 5 is equipped with clamp 36, and described clamp 36 is installed on the clamp box 9,10, is connected with extension spring 12 between the clamp box 9,10, and the lower end of clamp box 9,10 contacts with the rod end conical surface of follower lever 11.When pushing away on the follower lever 11, because the effect of the rod end conical surface, clamp box 9,10 overcomes the pulling force of extension spring 12, and clamp 36 is closed up.The size of clamp 36 folder amounts is regulated by clamp box upper end micrometer adjusting screw.But described clamp box 9,10 is installed on the toothed rotary table face 14 by two straight pins 13.When slide block 15 drags pull bar about 16 when moving back and forth, the workbench that is meshed with pull bar 16 can clockwise or counter-clockwise Rotate 180 °.

Fig. 3 is the structural representation of scalable core rod (punch).Among the figure, big punch 18 and small punch 17 are installed in the core rod box 19, clamp by location cassette holder 20 and clamping plate 21, slide rail 22 can protract as required or after contract, 23 is riser guide.By the effect of cam opposite end bar 24 and parts 25, the action of a series of complexity such as that big

small punch

18,17 can be finished is flexible, rising is to guarantee the demand of processing object.

Fig. 4 to Fig. 7 is the schematic diagram of each work step in the process.Among Fig. 4, the lower end of cut-out and shaping dies 32 is big punch 18 and small punch 17, and the figure right side is feeding guide plate 33 and following cutoff tool 31, and raw material to be processed becomes labor and materials 34 to stay between big punch 18 and small punch 17 after cutting off after feeding port A input.Among Fig. 5, because the effect of big punch 18, labor and materials are by the curved ∏ shape workpiece 29 that is pressed into.Among Fig. 6, big punch 18 retreats, and small punch 17 drops to the jaw top awaits orders, and gripping mechanism 5 buckles into ∏ shape workpiece in the shaping chain and closes up into shape workpiece 30.Among Fig. 7, after knitting the chain machine and finishing clasp, mould and clamp reset.Shaping chain 35 is held in the gripping mechanism 5.

Whole work step control of knitting chain is determined by the camshaft running status in the machine: when camshaft during from 0 ° of entry into service, clamp mould 8 begins feedings; When camshaft went to 90 °, cut-out and shaping dies were descending, and cutoff tool 2 cuts off labor and materials, and simultaneously big punch 18 is pressed into ∏ shape with labor and materials; When camshaft went to 135 °, big punch 18 retreated, and small punch 17 drops to the jaw top; When camshaft went to 180 °, gripping mechanism buckled into ∏ shape workpiece in the shaping chain and closes up into shape workpiece.Show that more than camshaft is that labor and materials are pressed the shape process at 0 ° to 180 °.It then is that small punch 17 is extracted the overall process that resets that camshaft goes to 360 ° of processes at 180 °: when camshaft goes to 225 °, die resets, clamp opens and counter-clockwise half-twist, hangs the small punch that weaves chain this moment and is treating to continue again to drop in the grip finger when clamp forwards to after little raising of open while of clamp; When camshaft went to 315 °, jaw was to wrapping in the outer shape workpiece of small punch that to hold be shaping; When camshaft went to 360 °, small punch was extracted from shape workpiece and is retreated to the limit, raised and stretched out, and prepared for repeating first element, and clamp clips the shaping chain that weaves and turns clockwise 90 ° and get back to original position simultaneously.
