The outer circle surface of the manufactured nail is free from shearing, extrusion and scraping. Thus the lux cutters have long service life; the length of the nail is stable; the nail machine has high driving rate and high productive efficiency.

Description

Rolling type wire holding feeder for nail machine

The utility model relates to nail machine roller clamping wire feed structure field.

Each nail machine factory design now, the nail machine of making, its wire feed clamping device are the band sword and rein in cutter holder and hold structure.This structure is in the wire feed process, and the band sword is reined in cutter iron wire is formed shearing, extruding; And in non-wire feed backhaul, the band sword is reined in edge because the active force of spring forms scraping again to iron wire; That is: each wire nail all has the scraping vestige of extruding vestige and length and wire nail, has directly influenced the surface quality of wire nail.Simultaneously, since about rein in edge directly with iron wire generation scraping friction, the cutting edge position produces high temperature, reduced the hardness of reining in edge, make very quick-wearing rust of cutting edge, cause wire nail length instability, and rein in cutter and need often change reconditioning, directly influence the driving rate of complete machine, reduced production efficiency.

The purpose of this utility model provides a kind of: the wire nail periphery is not subjected to shearing, extruding, scraping, reins in the cutter long service life, and wire nail length is stable, nail machine driving rate height, the nail machine roller clamping wire feed structure that production efficiency is high.

The utility model is achieved in that wire feed carriage 5 is by being loaded on front fuselage; Wire feed slide block base plate 6 is contained in the guide-track groove of wire feed carriage 5 with left and right sides gag 20 by bolt 22; Wire feed slide block 7 is contained in this groove; Steering block 8 is contained in the wire feed slide block 7; Transmission arm 16 is contained on the steering block 8; Steering block pressing plate 9 connects with wire feed slide block 7 by screw 21; Reining in knife rest 10 is contained on the steering block pressing plate 9; Wedge frame 1 with allow knife rest 11 be fixed on the steering block pressing plate 9 by bolt 17; Cutter relieving handle 14 and cutter relieving torsion spring 13 are fixed on by bearing pin 12 and allow on the knife rest 11; Left and right sides wedge 2 is fixed on the wedge frame 1 by bolt 3; Left and right sides cylinder is reined in cutter 4 and is contained in and reins in knife rest 10 left and right sides grooves, and its external cylindrical surface contacts with left and right sides wedge 2; Reining in cutter spring 15 is contained between wedge frame 1 or the wire feed bolt 19; Wire feed bolt 19 by locking nut 18 with rein in knife rest 10 and link.

Transmission arm 16 is contained in the groove of steering block 8.

Reining in knife rest 10 left and right sides grooves is symmetrical tilting.

Left and right sides wedge 2 and wedge frame 1 formed is shaped as isosceles trapezoid.

The utility model has the advantages that: the wire nail periphery is not subjected to shearing, extruding, scraping, reins in the cutter long service life, and wire nail length is stable, nail machine driving rate height, production efficiency height.

Below in conjunction with accompanying drawing, the utility model is described further with embodiment:

Fig. 1 is the utility model front view.Fig. 2 is the cutaway view of the B-B face of Fig. 1.Fig. 3 is that the C of Fig. 1 is to view.Fig. 4 is the partial sectional view at the A-A of Fig. 3 face.The vertical view that Fig. 5 obtains for the steering block pressing plate 9 above parts of taking away among Fig. 1.Fig. 6 is the prior art front view.Fig. 7 is that A at Fig. 6 is to view.Fig. 8 is the cutaway view at the A-A of Fig. 6 face.

1, wedge frame, 2, left and right sides wedge, 3, bolt, 4, left and right sides cylinder reins in cutter, 5, wire feed carriage, 6, wire feed slide block base plate, 7, the wire feed slide block, 8, steering block, 9, steering block pressing plate, 10, rein in knife rest, 11, allow knife rest, 12, bearing pin, 13, cutter relieving torsion spring, 14, the cutter relieving handle, 15, rein in the cutter spring, 16, transmission arm, 17, bolt, 18, locking nut, 19, the wire feed bolt, 20, left and right sides gag, 21, screw, 22, bolt, 23, iron wire.

Wire feed carriage 5 is fixed in front fuselage, wire feed slide block base plate 6 is connected in the guide-track groove of wire feed carriage 5 with left and right sides gag 20 by bolt 22, form the dovetail guide groove, wire feed slide block 7 matched in clearance are contained in this groove, steering block 8 places the circular trough in the middle of the wire feed slide block 7, and can freely rotate, transmission arm 16 is packed in the groove of steering block 8, can drive steering block 8 rotates with respect to wire feed slide block 7 together, can in the groove of steering block 8, do reciprocating linear motion again, like this, the swing of transmission arm 16 does reciprocating linear motion in the guide-track groove of wire feed carriage 5 by steering block 8 drive wire feed slide blocks 7.Steering block pressing plate 9 connects with wire feed slide block 7 by screw 21, reins in the guide-track groove that knife rest 10 is contained in steering block pressing plate 9, and can reciprocatingly slide.Wedge frame 1 with allow knife rest 11 be fixed on simultaneously on the steering block pressing plate 9 by bolt 17, cutter relieving handle 14 and cutter relieving torsion spring 13 are fixed on by bearing pin 12 and allow on the knife rest 11, pulling cutter relieving handle 14 like this can stir and rein in knife rest 10 to front slide, iron wire is passed left and right sides cylinder smoothly rein in cutter 4, left and right sides wedge 2 is fixed in the groove of wedge frame 1 by bolt 3, left and right sides cylinder is reined in cutter 4 and is installed in and reins in knife rest 10 left and right sides grooves, and its external cylindrical surface contacts with left and right sides wedge 2.Rein in the back medium pore that cutter spring 15 front ends rely on wedge frame 1, the rear end leans in the front aperture of wire feed bolt 19, wire feed bolt 19 with rein in knife rest 10 and connect, and can adjust the pressure of spring by rotation, locking nut 18 can make 19 lockings of wire feed bolt.After iron wire 23 passed nail machine roller clamping wire feed structure, left and right sides cylinder was reined in cutter 4 and all the time iron wire 23 is in the rolling clamped condition.Under the drive of transmission arm 16, wire feed slide block 7 does reciprocating linear motion, and makes left and right sides cylinder rein in cutter 4 is finished work of clamping wire feed and non-wire feed backhaul automatically by the movement locus of oneself cutter relieving work.
