Abstract

The utility model relates to a steel wire conveying device, in particular to a wire coil of a computer spring machine. A bundled bar is directly placed on a frame in general, the steel wires are easy to be winded and knotted during the conveying process, and the quality of the spring is affected because the tension of the steel wires is not stable. A wire coil 1 is driven by an electric motor, can be relatively rotated around the rotating axle of the electric motor and presents a sleeving-free state. The electric motor drives the wire coil only by the frictional force generated through the deadweight of the wire coil, and when the steel wire is used up, the rotation of the wire coil is easy to skid. Therefore, an adjusting screw cap 6 and a compression spring 8 are arranged in the center of a rotating axle 10, and the frictional force between the wire coil and the rotating axle can be adjusted at any moment. Since the feeding speeds of the spring machine and the wire coil 1 are not synchronous, a steel wire tension detector is arranged, when the feeding speed is excessively high and the tension of the steel wire is lost, the power supply of the electric motor is cut off by the detector, the spring machine carries out production by using the stored steel wires between the wire coil 1 and the spring machine, and once the stored steel wires are used up, the tension of the steel wires is enhanced, the tension detector is automatically supplied with the power supply, and the wire coil 1 supplies material to the spring machine.

Description

Computer coiling machine drum

Technical field

The utility model relates to a kind of raw material conveying equipment, is meant computer coiling machine drum specifically.

Background technology

Coil of wire unit is a raw material of making spring, manual production normally was placed directly on ground or the shelf in the past, along with the needs of coiling machine feed one enclose pull outward and give, in course of conveying because the rotation and the distortion of steel wire, after particularly turning over multi-turn, transporting velocity is faster the time, be easy to tie a knot around ringlet.If after having adorned motor-driven on the coil of wire unit underframe, feeding speed is difficult to guarantee absolute consistent again with materials speed.Tight during pine during steel wire enters spring when making machinery tension force, again because drum inertia is big, need to use more powerful motor, this is in frequent startup, when shutting down, and drum is bigger to the impact of motor shaft, and fault is many, is not durable; The purpose of this utility model is invented in order to address this problem.

Summary of the invention

Computer coiling machine drum is carrying raw material-coil of wire unit usefulness of making spring, mainly be made up of drum 1, lever 2, rotating shaft 10 etc., coil of wire unit is disposed across on the drum 1, is mounted on lever 2 peripheries, all around by the drum back-up ring of certain altitude round, it unlikelyly outwards is scattered.Drum drives with motor, but is not common with being rigidly connected that key fixes between drum and the rotating shaft, but drum can be made counterrotating " empty cover " around rotating shaft.There is hole, individual garden in drum central authorities, and the aperture just in time can hold rotating shaft 10, and drum is shelved on the rotating shaft cushion cap 10-1, are putting a vulcanite pad 11 between drum 1 and the rotating shaft cushion cap 10-1, and nationality is to increase frictional force.Whole drum usually surpasses 100 jin together with the deadweight of coil of wire unit, and rotary inertia is very big.Just in order to alleviate the impact of rotator inertia, be not rigidly connected Cai the drum sky is enclosed within the rotating shaft to the drum frequent motor starting.Only depend on the deadweight and the frictional force between the rotating shaft cushion cap of drum to drive the drum rotation, still reliable inadequately, particularly steel wire runs low, and when deadweight alleviated greatly, the rotation of drum was often skidded easily.For this reason, central authorities in rotating shaft 10 are provided with screw 10-2, with hex bolts 5, steel bowl 7 stage clip 8 and stage clip pad 9 are pressed on the drum, nationality is to increase the frictional force between drum and the rotating shaft, actual rotation state according to drum, can turn and regulate the pressure that nut 6 is adjusted stage clip, also promptly adjust the frictional force between drum and the rotating shaft.

When needs drum during to the feeding of computer coiling machine, the drum motorized motions, because drum and rotating shaft are not rigidly connected, when motor-driven power was not enough to overcome whole rotary inertias, drum 1 can skid on rotating shaft cushion cap 10-1, and the relative displacement of the rotation that lags behind has alleviated motor driving moment, the driving force that continues when motor makes drum 1 slowly rotate finally, just begin to carry steel wire, because the generation of pitch of the laps knotting has been avoided in the rotation of drum towards the coiling machine direction.Because the speed that coiling machine will be expected and the speed of drum 1 feeding can't guarantee absolute synchronization, the present invention is provided with a tension detector on the steel wire between drum 1 and the coiling machine for this reason, when the too fast tension force of feeding disappears, automatically cut off the power supply of drum motor, allow coiling machine use the storage steel wire between drum 1 and the coiling machine to produce, in case the steel wire that stores uses up, steel wire tension strengthens, and tension detector is connected the drum motor power again automatically.Drum 1 is rotated further and coiling machine is recovered feed.

Because the radial dimension of coil of wire unit has size, so this practicality is provided with four radial groove 1-1 on drum, lever 2 can be moved along groove 1-1, adjust according to the size of the first diameter of dish.When moving to correct position, fix with hex bolts 3 and pad 4.Lever 2 lower ends are connecting fixedly iron block, and the screw that is used for fixing bolt 3 is arranged above.

When a kind of spring of specification completes, need the transposing kind, in the time of sending the steel wire on the drum back to warehouse, can in 4 hole 1-2 on the drum, pierce into the segment iron wire, coil of wire unit outside, prick four road hoops, prevent the dish unit circle that looses, be convenient to transport.

The rim of certain altitude is arranged on the outer garden of drum, can stop steel wire outside drum, to be scattered, influence feeding.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Embodiment: shown in 3 accompanying drawings, drum 1 is carrying coil of wire unit and is slowly rotating, and carries steel wire towards the direction of coiling machine all the time; Overlapping a tension detector on the steel wire between drum and the coiling machine, according to the size cut-out of steel wire tension and the power supply of recovery drum motor, nationality is to regulate feeding speed.When there is size in coil of wire unit, control with lever 2 shift position on drum; When the rotary inertia of drum changes greatly, regulate nut 6 with rotation and control, keep best drum frictional force.

The effect that the utility model is useful is: guarantee that coil of wire unit keeps constant tension force in the feeding process, and do not tie a knot around ringlet, spring Coil-up is carried out smoothly.Can also use low-power machine, alleviate the impulsive force of drum motor.

Drum 1 diameter of the present utility model is changeable, looks the size of coil of wire unit and determines several specifications; Lever 2 also can have more than three or three, and the technical scheme that all employing equivalent transformations form all drops in the protection domain of the utility model requirement.
