Description

Automatic peeling device suitable for flat cable

Technical Field

The invention belongs to the technical field of automatic processing equipment, and particularly relates to an automatic peeling device suitable for a flat cable.

Background

A flat cable is widely used as a multi-core cable in mobile electrical devices, such as a traveling crane, an elevator, and the like. The flat structure is particularly suitable for the occasion of frequent bending, and is not twisted and folded neatly. The device is particularly suitable for electric connection among mobile electric devices in severe environments such as power generation, metallurgy, chemical industry, harbors and the like. For example, when the elevator moves up and down, electric energy and control signals need to be provided, and the cable does not influence the normal operation of the elevator, so that the flat cable is a linear type which can take both the electric energy and the control signals into consideration.

In order to facilitate the use of customers, when the cable leaves a factory, the outer skins of the connecting sections at the two ends of the flat cable need to be stripped. After retrieval, no peeling device for the flat cable exists, so that peeling is mainly performed manually at present, but the following outstanding problems exist: firstly, manual peeling occupies more personnel, but the efficiency is low and the cost is high; secondly, in order to enhance the stress capacity of the cable, a steel wire rope is added into the cable and is sintered with the sheath, so that the peeling difficulty is increased; and the strength is difficult to control when the sheath is manually cut, so that the thin cable inside is extremely easy to damage, and great potential safety hazard and waste are caused.

Therefore, the invention develops an automatic peeling device for the flat cable aiming at the bottleneck faced by the peeling process of the flat cable, and provides technical guarantee for peeling the outer skin of the flat cable. The device can greatly improve the processing efficiency and reduce the production cost of enterprises, and has wide application prospect and great economic and social benefits.

Disclosure of Invention

The invention aims to provide a safe, economic and efficient automatic flat cable stripping device, which provides guarantee for improving the processing efficiency of flat cables. The automatic flat cable peeling device realizes quick longitudinal cutting, variable thickness floating ring cutting and peeling completion on the premise of ensuring safety, and realizes accurate control of peeling length and cutting depth.

In order to achieve the purpose, the invention adopts the following design scheme:

an automatic peeling device for flat cables, as shown in fig. 1, comprises: a high-precision clamping and conveying fixed length device with the error of +/-0.5 mm; the error of the transverse wedge-shaped column type ball positioning device is +/-0.1 mm; a multi-cutter head self-adaptive slitting device; a variable thickness floating novel circular cutting device; a wedge cut into the peeling device; a lifting clamping mechanism and the like. The specific invention process is as follows:

the transverse wedge-shaped column type ball positioning device is characterized in that: in order to accurately position the flat cable at the transverse position and ensure that the variable-thickness transverse circular cutting cut-in depth is consistent with the thickness of the cable sheath, the wedge-shaped groove at one end adjacent to the high-precision pinch length control device is wider than the actual width of the cable so as to be convenient to smoothly enter, the width of the wedge-shaped groove at the other end is the same as the actual width of the cable, and the side wall of the equal-width groove with a certain length adopts a cylindrical ball so that the cable is not deformed when being transversely positioned, as shown in fig. 2.

Many tool bits self-adaptation rip cutting device, its characterized in that: two or more steel wires with enhanced strength are placed in the flat cable, and the steel wires and the sheath are completely sintered together in the sintering process of the sheath of the cable, so that the resistance is very high during later peeling, and the peeling cannot be easily performed, and the integral peeling is difficult. Therefore, the longitudinal cutting device with the multiple tool bits and the self-adaptive cutting depth and width is designed, the fixed-length cutting can be longitudinally completed, the resistance in the process of peeling the skin is greatly reduced, and the peeling purpose of the peeling knife is conveniently realized.

Become novel ring-cutting device that thickness floats, its characterized in that: the self-adaptive knife edge gap self-adaptive adjusting device is manufactured according to the distribution of the thin cables arranged in the flat cable, and the ring cutter is flexibly connected to a ring cutter rest, as shown in figure 3. The novel variable-thickness floating girdling device ensures that the cutting depth is changed along with the distribution change of the built-in cable, and the inner thin cable is not damaged under the condition that the outer skin of the cable is transversely cut as much as possible.

The wedge-shaped cutting-in peeling device is characterized in that: because the circular cutting incision gap is smaller, if a flawless skinning knife is adopted, the flawless skinning knife cannot enter the circular cutting incision, and the skinning task cannot be realized. The invention adopts a U-shaped peeling knife, the inner side of the U-shaped peeling knife is a knife edge, the section of the U-shaped peeling knife is wedge-shaped, and the knife edge and the cutting edge of the circular cutting knife are positioned on the same vertical line in the transverse direction, as shown in figure 4. The invention not only ensures the accurate and reliable cut-in, but also ensures the safety and reliability of the cutter, and the cutter cannot be bent or broken easily.

Through the invention process, the safe and economic automatic peeling device for the flat cable is invented, and the purposes of improving the factory treatment efficiency of the flat cable, saving the labor input and reducing the cost can be achieved.

The invention has the advantages and positive effects that:

1. the invention can accurately control the cutting depth, ensures that the outer skin of the flat cable is completely cut and the internal thin line is not damaged, and avoids the waste caused by manual cutting too deep;

2. the device needs manual intervention in the first cable threading, and does not need manual participation in the subsequent process, so that the processing efficiency is improved, a large amount of manpower is saved for enterprises, and the production cost of the enterprises is greatly reduced;

3. the device is safe to use, convenient to maintain, economical and reliable, and is an advanced flat cable stripping device.
