Abstract

The utility model belongs to the field of mechanical tools, in particular to a wheel type pay-off which comprises an upper wire threading wheel, a lower wire threading wheel, a rotary support arm andan upright post, wherein the upper wire threading wheel is installed on the rotary support arm, the lower wire threading wheel is installed on the upright post, and the rotary support arm is connectedwith the upright post. The pay-off is characterized in that a threading alarm ring is installed on the rotary support arm, the threading alarm ring is mounted on a bracket, and is provided with a block, a restoring spring is arranged on the tail portion of the threading alarm ring, and an alarm switch is arranged on the bracket. The work noise is small, wires are straightened by the pay-off before entering a wire stretcher, are not easy to knot, the pay-off can automatically alarm and stop working if wires are knotted, thereby effectively protecting the wire stretcher.

Description

Wheeled pay off rack

Technical field:

The utility model belongs to the machine tool field, is a kind of wheeled pay off rack concretely.

Background technology:

In large-scale backguy unit, unwrapping wire is first algorithm, the effect of unwrapping wire directly has influence on the workmanship that the line sample enters the backguy main frame, the dolioform pay off rack of the many employings of existing pay off rack, but dolioform pay off rack is because the reason of its shape, and wire rod is because the distortion when being subjected to lopping, in the process of unwrapping wire, often escape from, cause main frame normal operation to cause frequent shutdown from the dolioform edge, hurdle that rolls; When being used for the high speed wire mill, dolioform pay off rack causes noise very big owing to the wire rod friction more; It is big to the wire surface friction that dolioform pay off rack rolls the hurdle, easily abrades wire surface, is unfavorable for next step drawing; Because traditional dolioform pay off rack only rolls the hurdle through one, fully reason is not straight for the wire rod of being emitted, when entering the wire mill first road backguy mould, if reason is not straight for wire rod during inlet wire, but knotting or crooked state, it is excessive then can to make wire mill produce the pulling capacity of moment, easily the main frame gear is produced and impacts, and can damage gear when serious.

Then existing dolioform pay off rack exists that noise is big, friction is big, unwrapping wire is discontinuous, reason is directly insufficient, the line sample when entering pay off rack, the problem of tangled up and knotted easily.

Summary of the invention:

In view of above present situation, the utility model provides a kind of wheeled pay off rack, both solved pay off rack and had that noise is big, friction is big, the incoherent problem of unwrapping wire, it is directly insufficient to the wire rod reason to have overcome existing pay off rack again, make the line knotting easily, thereby make the problem of wire mill cisco unity malfunction, and then improved the unwrapping wire rate.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of wheeled pay off rack, comprise wire-crossing wheel, following wire-crossing wheel, pivotal support arm, column, last wire-crossing wheel is installed on the pivotal support arm, following wire-crossing wheel is installed on the column, and pivotal support arm links to each other with column, it is characterized in that: the alert ring of report from a liner was installed on the described pivotal support arm, the alert ring of described report from a liner excessively is rack-mount, cross the alert ring of report from a liner and be provided with link stopper, cross the alert ring of report from a liner afterbody retracing spring is housed, alarm switch is arranged on the support.

Described alarm switch is the induction alarm switch;

The described retracing spring other end is connected with the pivotal support arm bottom;

Described induction alarm switch links to each other with the circuit of motor, reports to the police and then cuts off the electricity supply automatically.

The utility model advantage: operating noise is little, and is stretching by pay off rack before wire rod enters wire mill, is not easy knotting, if the wire rod knotting, pay off rack meeting auto alarm also quits work, and has protected wire mill effectively.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 was the alert ring structure scheme drawing of report from a liner.

In the accompanying drawing on 1. 2. times wire-crossing wheels of wire-crossing wheel, 3. pivotal support arms, 4. columns 5. cross the alert ring of reports from a liner 6. supports 7. link stoppers 8. retracing springs 9. alarm switches

The specific embodiment:

Wheeled pay off rack, comprise wire-crossing wheel, following wire-crossing wheel, pivotal support arm, column, last wire-crossing wheel is installed on the pivotal support arm, following wire-crossing wheel is installed on the column, and pivotal support arm links to each other with column, it is characterized in that: the alert ring of report from a liner was installed on the described pivotal support arm, the alert ring of described report from a liner excessively is rack-mount, cross the alert ring of report from a liner and be provided with link stopper, cross the alert ring of report from a liner afterbody retracing spring is housed, alarm switch is arranged on the support.

Alarm switch is the induction alarm switch; The retracing spring other end is connected with the pivotal support arm bottom; The induction alarm switch links to each other with the circuit of motor, reports to the police and then cuts off the electricity supply automatically.

Wire rod is introduced from crossing the alert ring of report from a liner, if wire rod is in the process of introducing, take place to twine or the knotting bending, then wire rod will touch the alert ring of report from a liner, if when crossing angle that the alert ring of report from a liner up carried by wire rod greater than 30 degree, the link stopper that was installed on the alert ring of report from a liner will trigger alarm switch, alarm switch is an inductive switch, when link stopper during infinitely near inductive switch, will trigger inductive switch, make its warning, switch links to each other with motor, then cut off the pay off rack power supply after the warning, treat issue handling after, again by artificial power-on switch.

Introduce, process shelves wire loop by the alert ring of report from a liner from crossing for wire rod, after the wire-crossing wheel traction is made in order up and down, enters the backguy main frame.Because wire rod has been report from a liner alert ring, baffle ring, alignment is made in the traction of wire-crossing wheel in order up and down, outlet is straight substantially, thereby can not constitute impact to main frame, has protected main motor and gear case effectively, has realized steady drawing, has improved the quality of drawn wire.Adopt wheeled excessive wire rod, then friction is few, and noise is low, and wire surface does not have scratch substantially.
