Description

Stainless steel wire pull is with indiscriminate line automatic stop device

Technical Field

The utility model relates to a detent field, especially a nonrust steel wire pull is with indiscriminate line automatic stop device for steel wire unwrapping wire.

Background

The stainless steel wire needs to be drawn and pulled for many times in the production process, the stainless steel wire needs to be wound and paid off for many times in the drawing process, the stainless steel wire runs regularly and stably in the winding process, but when the stainless steel wire is paid off, particularly when the stainless steel wire with a small diameter is paid off, the stainless steel wire is very soft in texture due to the small diameter of the stainless steel wire, the winding process is generally a winding type, when the stainless steel wire is paid off, the wire outlet end of the stainless steel wire is very easy to cause the winding disorder of the stainless steel wire, the wire is very easy to break, and even safety accidents are caused, therefore, measures are generally taken to shut down in time, and the disorder. The shutdown requirement is timely and fast, if the production line continues to work after the wire is disordered, the wire breakage is easily caused, the broken end of the stainless steel wire can damage the die, meanwhile, the stainless steel wire needs to be threaded again after the wire breakage, the workload of workers is increased, and the production efficiency is reduced.

In order to solve the problem of wire disorder, related enterprises have conducted certain research and development on the locking device, for example, the invention patents in china: an elevated pay-off stand (grant No. CN104475487B) discloses a scheme that when the steel wire on the incoming wire is tangled and knotted, the steel wire can not be guided from a top pulley, and a following wire drawing machine is still in operation, so as to ensure that the steel wire is not broken. The front end steel wire drives the climbing mechanism to move upwards, and in the moving process, the counterweight block straightens the steel wire through gravity, so that the normal operation of the wire drawing machine is ensured. If the steel wire still entangles, after the part of crawling reaches certain height, the locating lever touches the dog, and whole equipment is shut down, guarantees safety, has avoided mixing the line. After the problem of knotting of the messy wires is solved, the equipment is continuously operated to pay off the wires. Climbing mechanism still locates at the eminence this moment, through trampling pedal part, promotes the lifter of push rod part, and the lifter promotes the push rod to the outside again, and the telescopic link on the push rod drives the locating plate moves to the outside, and the telescopic link overcomes spring pressure and stretches out to the locating plate outside, and the steel wire on the not hard up climbing mechanism to make the steel wire under the effect of climbing mechanism gravity, get back to the bottom once more, carry out the unwrapping wire operation once more. According to the scheme, the machine can be stopped in time when the steel wires are disordered, but after the disordered wires are finished, the climbing mechanism needs to manually tread the pedal part to return to pay off the wires again, and the pedal part is matched with the push rod part, so that the complexity of the machine is increased, and other potential safety hazards are possibly brought.

Other relevant trades have also studied the problem of disorderly line shut down, for example, the steel cable unwrapping wire, chinese utility model patent: an automatic stop device for disordered wires (No. CN204689253U) is provided, wherein a wire supply frame is provided with a chute from top to bottom, a guide wheel is fixedly arranged at the upper end of the chute of the wire supply frame, a sliding block with a heavy object block is arranged at the lower end of the chute, the sliding block is connected with the chute in a sliding way, a pulley is fixed on the sliding block, a limiter capable of limiting the movement of the sliding block is arranged on the wire supply frame, a protective cover is covered on the guide wheel and the movable pulley, a lead frame is arranged on the side surface of the upper end of the wire supply frame, and a lead wheel is arranged on the. Through this kind of scheme, can prevent to break away from taking place between high-speed wire winding's in-process steel silk thread and guide pulley and the movable pulley on the one hand, heavy object piece can alleviate the speed that the movable pulley rises in addition to avoided travel switch by the possibility that the lug was washed out, and then played safe effect promptly, makeed the indiscriminate line parking more sensitive. However, due to the time delay between the travel switch and the PLC, the travel switch is arranged at the upper end of the wire supply frame, and the sliding block moves under the inertia effect and is easy to collide with the upper guide wheel; in addition, after the arrangement of the disordered wires is finished, the sliding block naturally falls under the action of gravity, and the heavy object blocks are arranged below the sliding block, so that the inertia is large, the steel wire is easily pulled when the steel wire rapidly falls, the performance of the steel wire is influenced, meanwhile, the heavy object blocks fall to the bottom and are influenced by the inertia, large impact force can be generated between the heavy object blocks and the bottom plate, and other damage can be caused.

Therefore, further improvements in the wire jumbling automatic stop device are needed.
