Description

Multistation hydraulic stripping and press-bonding machine for cable

The utility model is high and low voltage electrical equipment and communication device manufacturing industry are carried out comprehensive processing to cable a special equipment.

Cable (have on the industry be referred to as soft bus) needs press a connector lug in its termination, could connect with each electric device.Its course of processing is: 1, cable fixed length blanking; 2, peel off insulating barrier; 3, make the cable termination and corresponding connector lug crimping of different size line warp; 4, ward off tin and handle (press the industry standard of high and low voltage electrical equipment product quality, can not ward off tin) through the connector lug of cold presswork.

To the above-mentioned course of processing, existing still do not have comparatively ideal special equipment, and each producer can only adopt different equipment blankings respectively.When peeling off insulating barrier and crimping connector lug, be manual operations,, peel off with scissors again as cutting off with electrician's hilt insulating barrier.Electrician's knife as if undue force, often cuts off lead when the incision insulating barrier.When the crimping connector lug, mostly be and beat with tup.Because the connector lug with the method crimping is not firm, contact resistance is big, during galvanization the contact temperature rise too high, thereby to improve with the way of warding off tin.Some specific purpose tools and equipment that the producer that has uses, because of purposes is single, use change frequent, complex operation, it is former thereby can not be widely adopted that production efficiency is low etc.As with hand-hydraulic pincers crimping single line, remove the processing that mold exchange external demand repeatable operation more just can be finished a end of a thread for 11 times, labour intensity is big, and production efficiency is low.The producer that also has adopts many punch presses, and cable is carried out the crimping of blanking and all size connector lug, takies several equipment, substantial contribution and place.

The purpose of this utility model is to provide a kind of production efficiency height, multipurpose, multistation, cable comprehensive process special equipment easy and simple to handle.

The utlity model has following structure:

One rotating platform is arranged on horizontal work top, forming and have the pressure welding mold of different cavity dimensions, rotating platform below with several by upper and lower module by a shear(ing) die of being made up of upper and lower blade on the rotating platform table top is one can make the oil cylinder of shear(ing) die bottom knife or the pan-up of pressure welding mold lower module by push rod.

For making the cable cutting length be easy to measure, be preferably in said work top and be provided with a positioning rule.

For further improving work efficiency, increase usefulness, the utility model, preferably the end at horizontal work top is a rotating platform, the other end is a wire stripping mechanism: have one by last on (1) rotary table top, the shear(ing) die that bottom knife is formed and several are by last, the pressure welding mold of different cavity dimensions is formed and had to lower module, rotating platform below is one can make the oil cylinder of shear(ing) die bottom knife or the pan-up of pressure welding mold lower module by push rod, (2) wire stripping mechanism comprises: a, form by compact heap up and down for one, pressure die with several nibs in different apertures, one of b places after the pressure die, by last, bottom knife is formed, the stripping mould of nib with several band circular arc cutting edges in different apertures, c, one connects with the stripping mould is fastening, the slide of can be by hydraulic oil cylinder driving and moving forward and backward along the guide rail level, d, one is in pressure die and stripping mould below, can make down the oil cylinder of compact heap and the pan-up simultaneously of stripping mould bottom knife by jack unit.

The course of work of the present utility model and using method are as follows: 1, cable is penetrated shear(ing) die, after the positioning rule fixed length, move on the oil cylinder piston, make on the shear(ing) die bottom knife by push rod and move, cut off cable.2, the cable of having no progeny under the fixed length, by its standard wire lattice (as 30A, 40A, 60A, 80A, 100A, 125A etc.), insert in the nib of wire stripping mechanism pressure die respective aperture, move on the oil cylinder piston to make down on the compact heap and move, compress cable, simultaneously stripping mould bottom knife moves on also, and the circular arc cutting edge cuts off its insulating barrier along the cable periphery and just stops, and does not hinder plain conductor.This moment control system under the effect of sequence valve, oil cylinder makes on slide and the stripping mould, move after one level of bottom knife a segment distance, the cut-out the insulation displacement lead.3 leads of peelling off insulating barrier are bumped into connector lug, put into the pressure welding mold die cavity of the corresponding specification of rotating platform, and this pressure welding mold is turned to oil cylinder push rod top, move on the oil cylinder piston, and module is closed and lead is crimped on connector lug up and down.

Advantage of the present utility model is:

1, a tractor serves several purposes (blanking, crimping or add wire stripping) is stable and reliable for performance, can significantly reduce equipment investment, saves floor space,

2, can not scratch or cut off lead during wire stripping, crimping firmly need not warded off tin, and a plurality of stations are arranged, and does not need more mold exchange during use, operates simple and easy.

3, can reduce labor intensity greatly, enhance productivity, have distinct economic.

Fig. 1 is embodiment master's TV structure schematic diagram.Fig. 2 is an embodiment plan structure schematic diagram.Fig. 3 is a pressure welding mold structural representation among the embodiment.Fig. 4 is a upper and lower compact heap structural representation among the embodiment, and wherein (a) is main looking, (b) for overlooking.Fig. 5 is the hydraulic schematic diagram of embodiment.

Embodiment: see Fig. 1-4.One end of horizontal work top 1 is a rotating platform 2, and the other end is a wire stripping mechanism.The table top of rotating platform 2 is provided with 7 pressure welding molds 3 and shear(ing) die 4 of different size.Among Fig. 1 and 25 and 6 is respectively the upper and lower blade of shear(ing) die, and 7 is oil cylinder, and 8 is the shear(ing) die fairlead, and 9 is clam member, and 10 is positioning rule.11 is lead among Fig. 3, and 12 is connector lug, and 13 and 14 are respectively the upper and lower module of

pressure welding mold

3, and 15 is push rod, and 16 is back-moving spring, and 17 for adjusting the guide vane end stop of upper and lower module pressing degree.In wire stripper by on compact heap 18 and following compact heap 19 form a pressure die that 6 different apertures nibs are arranged.Correspondingly, also form one by stripping mould upper blade 20 and bottom knife 21 and have 6 different apertures, the stripping mould of the nib of band circular arc cutting edge.Among Fig. 1 and 2 22 is slide, and 23 is guide rail, and 24 is oil cylinder, and 25 is jack unit, and 26 is oil cylinder, and 27 is oil pump, and 28 is motor.

The hydraulic principle of present embodiment is seen Fig. 5, and hydraulic oil carries out the idle loop oil sump tank through three position four-way electromagnetic valve 29 and 30 after oil pump 27 starts.When valve 30 right-hand members changed to meta, pressure oil entered oil cylinder 7 back cavities, promoted shear(ing) die or pressure welding mold work.Reach overflow valve 31 overflows after the rated pressure, valve 30 left ends change to meta, and oil cylinder 27 resets, and cut off or crimping work finishes.Electromagnetically operated valve 29 left ends change to meta, and pressure oil enters oil cylinder 26 back cavities, promote to move crush-cutting cable insulating barrier on the jack unit 25.This moment, system works pressure raise (this system works pressure is 7MPa), when rising to 6.5MPa, and one way sequence valve 32 actions, pressure oil enters oil cylinder 24 ante-chambers, and piston retreats, and the cable insulating barrier is peeled.When reaching rated pressure, overflow valve 33 overflows, electromagnetically operated valve 29 right-hand members change to meta, when pressure oil enters the ante-chamber of oil cylinder 26 and oil cylinder 24 back cavities respectively, power on reset, wire stripping finishes.
