Description

Novel preformed armor rods make-up machine

Affiliated technical field:

The utility model relates to a kind of manufacturing technology of making preformed electric armour clamp in the mechanical manufacturing field, and it is a special equipment of producing the metal preformed armor rods.

Background technology

Also do not have the preformed armor rods make-up machine of typing at present on the domestic market, this kind equipment all is that electric armour clamp manufacturing enterprise researches and develops voluntarily, so pattern is multifarious, and performance difference is bigger.The preformed armor rods make-up machine generally is made up of guide frame, wire feed gear-box, shaping mould system and frame four major parts.The operation principle of preformed armor rods make-up machine is wire is pressed in movable wire feed rolls and fixedly between the wire feed rolls, by the rotation of wire feed rolls, wire is sent into shaping mould process the spiral preformed armor rods.From preformed make-up machine operation principle as can be seen, have only wire feeding force to reach enough big, and under the situation of quite stable, just can produce qualified spiral preformed armor rods.The size one of wire feeding force is relevant with the number of active wire feed rolls, the 2nd, and relevant with frictional force between active wire feed rolls and the wire.

In Fig. 6, pre existing hank knotting make-up machine transmission system shown in Figure 7, have only fixedly wire feed rolls 5 and gear to be linked and be the active wire feed rolls, 6 of movable wire feed rollss play the wire effect that compresses.That is to say and have only fixedly that the frictional force between the wire feed rolls 5 and wire could form wire feeding force, and the frictional force between movable wire feed rolls 6 and the wire also can consume the part wire feeding force.

In addition, the movable wire feed rolls 6 of existing type all is to adopt rigidity to compress mode, because the wearing and tearing of wire feed rolls cylindrical arc groove and the variation of wire diameter tolerance all can cause the variation of pressure between wire feed rolls and the wire, thereby can cause the fluctuation of wire feeding force.The rotation of silk dish also is to spur by the wire feeding force that wire feed rolls produces, because silk dish galloping also can cause the fluctuation of wire feeding force.These factors all can influence the quality of spiral preformed armor rods.

Summary of the invention

Do not increase the number of wire feed rolls in order to increase wire feeding force,, keep stable in order to make wire feeding force in order to reduce the wire surface pressure.The utility model provides a kind of novel preformed armor rods make-up machine.

The technical solution adopted in the utility model is:

One, improves the kind of drive.As shown in Figure 2, this novel wire feed gear-box partly adopts four pairs of wire feed rolls wire feeds, and fixedly wire feed rolls 5 (I, II, III, IV) and corresponding with it movable wire feed rolls 6 (I ', II ', III ', IV ') all link with travelling gear, make eight wire feed rollss all become initiatively wire feed rolls.Fixedly wire feed rolls 5 and movable wire feed rolls 6 rotate round about with the speed that equates, total wire feeding force is eight wire feed rollss and wire frictional force sum, thereby do not increasing the total number of wire feed rolls, it is long-pending not increase the moulding body, do not increase under the condition of wire pressure, wire feeding force has been increased more than one times.After movable wire feed rolls 6 becomes initiatively wire feed rolls, at adjustment activity wire feed rolls 6 and fixedly will inevitably cause the variation of centre-to-centre spacing between gear between the wire feed rolls 5 in the gap, so travelling gear has adopted involute gear.Because the angular speed of involute gear only with the proportional relation of the base radius of two gears, after gear is made, its base radius be determine constant, so even two gear centres are apart from slightly changing, its gearratio and transmission continuity do not change.

Two have improved the mode of compressing.As shown in Figure 4, this novel wire feed gear-box part has increased elastic pressuring clamping device on the slide block 7 that movable wire feed rolls 6 is housed.This device by movable wire feed rolls 6, slide block 7, adapter sleeve 8, elastic block rubber 9, compress gasket 10, compress leading screw 11 and handwheel 12 is formed.Elastic block rubber 9 is through necessarily having passed to slide block 7 with pressure after the compression, slide block 7 drive activity wire feed rollss 6 are pressed in wire fixedly on the wire feed rolls 5, even wire feed rolls cylindrical arc groove in use has certain wearing and tearing like this, or the wire diameter tolerance has certain variation, pressure between two wire feed rollss and the wire is remained unchanged, thereby make wire feeding force keep stable.

Three, increase tensioning apparatus.As shown in Figure 1, this novel guide frame part was provided with two mutually perpendicular tensioning apparatus 1 before wire enters wire feed rolls.As shown in Figure 5, this device is by seal wire cover 13, and moved cross beam 14 is regulated bolt 15, and regulating wheel 16 and fixed cross beam 17 are formed.Two regulating wheels 16 are arranged on the moved cross beam 14, regulating under bolt 15 effects, moved cross beam 14 can move up and down along two heel posts, is used for regulating the distance between the regulating wheel 16 up and down, to reach the effect of regulating wire in tension power; Three regulating wheels 16 are housed on the fixed cross beam 17, and it is fixed on device on the frame 4 by bearing.First tensioning apparatus mainly works to reduce vertical vibration, and second tensioning apparatus mainly works to reduce the horizontal direction vibration.

The beneficial effects of the utility model are: dwindled the volume of preformed armor rods make-up machine, increased wire feeding force, alleviated running over and injure of wire surface, kept the stable of wire feeding force, improved the crudy of spiral preformed armor rods.

Among the figure: 1, tensioning apparatus, 2, the wire feed gear-box, 3, the shaping mould system, 4, frame, 5, fixing wire feed rolls, 6, movable wire feed rolls, 7, slide block, 8, adapter sleeve, 9, elastic block rubber, 10, compress gasket, 11, compress leading screw, 12, handwheel, 13, seal wire cover, 14, movable lock piece, 15, regulate bolt, 16, regulating wheel, 17, fixed cross beam.

The specific embodiment

In Fig. 1, wire enters between four pairs of wire feed rollss after by tensioning apparatus, and the arc groove on the wire feed rolls is basic identical with wire.Because fixedly wire feed rolls 5 rotates round about with movable wire feed rolls 6 constant speed under travelling gear drives, under the effect of frictional force, wire is being pushed away by two wire feed rollss and is moving right.

In Fig. 2, movable wire feed rolls I ', II ', III ', IV ' and fixedly wire feed rolls I, II, III, IV are corresponding, and they are with identical speed, and rotation travels forward thereby can promote wire evenly in the opposite direction.

In Fig. 3, the operating range of movable wire feed rolls 6 is less, little to two gear centres apart from influence, the displacement of supposing movable wire feed rolls 6 is 5 millimeters, the former centre-to-centre spacing of two gears is 70 millimeters, centre-to-centre spacing after moving is about 70.178 millimeters, compares with former centre-to-centre spacing only to differ from 0.178 millimeter, and is therefore little to the transmission performance influence of two gears.

In Fig. 4, dextrorotation handwheel 12, compressing leading screw 11 moves downward, compress gasket 10 and elastic block rubber 9 are compressed, and pressure is passed to slide block 7, slide block 7 drive activity wire feed rollss 6 move downward, wire is pressed on fixedly on the wire feed rolls 5, the strain of elastic block rubber 9 makes wire feed rolls and pressure wiry keep constant, thereby makes wire feeding force keep stable.

In Fig. 5, wire is passed seal wire cover 13, bolt 15 is regulated in rotation, moved cross beam 14 drives two regulating wheels 16 in top and wire is pressed on three regulating wheels 16 of fixed cross beam 17, make motion wiry increase certain resistance, the vibration force that this resistance can balance silk dish bumpy motion produces.By regulating bolt 15 the wire tension adjustment is arrived suitable degree, cross conference and consume too many wire feeding force, too small meeting reduces the effect of tensioning apparatus, be according to wire diameter size and the suitably adjustment of hardness height.
