Abstract

The utility model relates to a device component for cable production, aiming at solving the technical problem by providing a passively drawing type brake homogenizer which ensures stable operation of a conductor and continuous production process and has characteristic of good quality of products. The technical solution of the utility model is that: the brake homogenizer drawing passively comprises a stand which is vertically provided with a rotatable draw disc rotating shaft; the draw disc is sleeved on the rotating shaft of the draw disc, wherein the stand is also provided with a lever; a friction plate arranged at one end of the lever is touched on a disc surface of the draw disc and the other end of the lever is sleeved with a weight unit capable of sliding left and right.

Description

The passive unwrapping wire even device that brakes

Technical field

The utility model relates to passive unwrapping wire on equipment unit, especially the electric cable foaming machine that a kind of cable the produces even device that brakes.

Background technology

At present, one important operation of production coaxial cable is exactly to coat the insulation foaming layer to form heart yearn outside conductor (as copper wire, welding wire, copper-clad aluminium wire etc.).Common conductor coats the method for insulation foaming layer outward, mainly is to utilize foaming machine extrusion molding on the outer surface of conductor to form the insulating barrier that surrounds conductor.And the quality of heart yearn quality for performances such as the characteristic impedance of product, decay, return losses, all plays a part decision; Guaranteeing under the quality of the conductor prerequisite of (as: electric property, good suppleness, uniformity have or not greasy dirt, dust etc.) that it also is crucial keeping conductor can stably enter the foaming head in the core wire foaming process.

At present, the conductor outsourcing covers in the production technology of putting the insulation foaming layer, mainly there is following shortcoming: during 1, owing to core wire foaming, what adopt is that passive unwrapping wire (is twining the draw drum of conductor D, be set in the rotating draw drum rotating shaft that vertically is provided with, under the pulling of conductor, rotate, discharge conductor simultaneously); In operation process, rotating speed is not very even (as: iron pan trembles up and down in the sometimes fast and sometimes slow or rotation process of rotating speed), and the hauling speed of draw drum and core wire foaming machine is asynchronous, causes conductor can't stably enter the foaming head.2, conductor (as copper wire, welding wire, copper-clad aluminium wire etc.) is when making, and essential elder generation is through wire drawing and annealing process.Through the metal of wire drawing, annealing process, its suppleness and tensile strength all will descend a lot, stick together easily.Conductor bears pulling force (direction is shown in the arrow A) in the unwrapping wire process, because of mutual haircuts and conductor discontinuity between the conductor, cause conductor to break easily; After conductor was broken, equipment also needed to start shooting again, thereby caused unnecessary waste of material.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of even device of brake of passive unwrapping wire is provided, and this even device that brakes should be able to guarantee that conductor even running and production process do not interrupt continuously; The characteristics that also have good product quality simultaneously.

The technical solution adopted in the utility model is: a kind of passive unwrapping wire even device that brakes, comprise frame, one rotating draw drum rotating shaft vertically is set on the frame, draw drum is set in the draw drum rotating shaft, it is characterized in that also being provided with on the frame lever, the friction plate of lever one end setting presses on the card of draw drum, the weight device that the other end socket of lever can horizontally slip.

Described friction plate is the rubber skin.

The utility model is by installing lever on the frame of location draw drum rotating shaft, one end of lever is connected with the friction plate that the card with draw drum touches, friction plate has increased the frictional force between the draw drum, has guaranteed that draw drum conductor in the unwrapping wire process can move reposefully; Having solved copper wire causes the copper wire that occurs in the haircuts and unwrapping wire process between copper wire and the copper wire to break problem behind wire drawing and annealing easily; Guaranteed that copper wire does not interrupt in process of production continuously; Avoided the unnecessary waste that produces because of copper wire fracture.Simultaneously, the characteristics that also have good product quality.The utility model is also at the other end of lever socket one weight device that can horizontally slip also, and the size of weight device scalable frictional force improves the result of use of the even device of brake.In addition, the change of this structure is also very simple, and outer consonance self-control all can realize.

Description of drawings

Fig. 1 is a working state schematic representation of the present utility model.

Embodiment

As shown in the figure, this passive unwrapping wire even device that brakes comprises frame 4, and a rotating draw drum rotating shaft 3 vertically is set on the frame; Suit one draw drum 2 in the draw drum rotating shaft, the card width of draw drum generally is about 85cm; It more than is the location structure of existing draw drum.

Improvement of the present utility model is: a lever 6 also is installed, the friction plate 1 that an end setting of lever and the card of draw drum touch on the frame 4.Friction plate can increase and the draw drum card between frictional force, make draw drum even at unwrapping wire process medium speed; Solved copper wire and broken problem, avoided the unnecessary waste that produces because of the copper wire fracture at the copper wire that causes haircuts between copper wire and the copper wire behind the wire drawing and annealing and in the unwrapping wire process, occur.The other end of lever is socket one weight device 5 that can horizontally slip also, weight device can be changed or increases the weight of weight device or carry out the adjusting of frictional force by the move left and right weight device according to the weight of iron pan (containing conductor), whole device can be regulated as required, improve result of use.

As further improvement of the utility model, described friction plate is selected the rubber skin for use, to improve the anti-wear performance of friction plate.

Claims

1, a kind of passive unwrapping wire even device that brakes, comprise frame (4), one rotating draw drum rotating shaft (3) vertically is set on the frame, draw drum is set in the draw drum rotating shaft, it is characterized in that also being provided with on the frame (4) lever (6), lever one end is provided with friction plate (1) and presses on the card of draw drum (2), and the other end of lever slides weight device (5) is set.
