Description

Object straightening feeding wears device

Technical field

The utility model is related to a kind of object straightening feeding and wears device, espespecially a kind of to wear inside cored wire to heat pipe Feeding wears device.

Background technology

With scientific and technological constantly evolution, nowadays many products for being dependent on manpower manufacture in the past more or less can be taken by machinery Generation artificial manufacture, this trend automated can not only improve the efficiency and accuracy during production, can also save manufacturer Cost, while allow human resource distribution to need more high degree of skill and machinery compared with the operation that can not replace.

But the process for manufacturing product is ever-changing, and not every kind of process successfully can be converted into mechanical system by manpower Make, therefore among manufacturing industry now, still need for being dependent on a large amount of manpowers and carry out many repetitionizations and the system of mechanization Make flow.

For example, in a kind of manufacturing process for processing tube and its internal core, its process is will be in tubulose Specific cored wire or other bars are placed into thing, and when tube caliber is too small, cored wire is worn into inside tube Process will become difficult, because the process is just as the hole that the end of a thread is passed through to tailor's pin in tailor, if this process Cored wire straightening is not evened up, then its fault rate will be very high；In addition, for wearing into these cored wires in tube, it leads to Often before wearing all it is to be rolled into the mode of a core circle to store, therefore when to be worn, its cored wire generally all can be because prolonged Wind and out-of-flatness, further the difficulty of increase machining；Therefore, in the prior art, such a first flatten cored wire wears again Enter the process of tube, carried out by manually.

And such a process, it can especially be used in the manufacturing process of heat pipe, the purpose of heat pipe is to assist electronics The radiating of instrument such as mobile phone or computer-internal, and be intended to the constantly lifting of these electronic instrument efficiency but simultaneously reduce or gently Quantify its external form, the electronic building brick used inside it certainly will also need constantly to reduce in volume, therefore due to the body of heat pipe Product constantly reduces, and needs the difficulty for wearing cored wire to be just consequently increased inside it, improves its difficulty to be automated, therefore, Now mostly the process of such a heat pipes just like it is foregoing be all to be carried out with manpower, but the demand of intelligent product only can not Disconnected increase, therefore how to be effectively improved the efficiency of manufacturing process and automate it, it is desire most ardently solution in the prior art one Item problem.

It is occupation mode of the present utility model below.

The utility model is for straightening and wears the automation equipment of wire body, and the generally wire body such as this is all the side with winding Formula is wound on a spool, therefore user is first intended to the spool that straightening wears and is arranged into spiral post of the present utility model In, and by wire rod by the spool it is stretched come and by the pulley carry out first time straightening, but because and not all wire rod All it is to be wound in the way of spool, therefore also can be without this step.

Refer to shown in Fig. 1, Fig. 2 and Fig. 3, wire rod is then passed through to the cam of grade first of the grade pinch roller assembly 30 one by one 321 and first concave wheel 322, herein during one, wire rod can be because by the slight squeeze of the first cam 321 and the first concave wheel 322 The surface of the possible extreme out-of-flatness of its script is deformed and gradually flattened, simultaneously, because the diameter thickness of wire rod has different, is located at Elastic parts 314 on upper supporting part 312 can make supporting part 312 that there is a upward clearance to carry out the line in response to different thicknesses Material；After by grade first cam 321 and the first concave wheel 322, wire rod is then worn into material conveying platform 21 by feeding opening 23 On feeding track 22, enter feeding track 22 after, the second cam 33 can to wire rod carry out last time straightening, due to this When wire rod be more smooth state, therefore the second cam 33 will not be collocated with addition a concave wheel wire rod is entered shape torsion.

Refer to shown in Fig. 4, Fig. 5 and Fig. 6, wire rod enters after feeding track 22, the operable clamping part 40 of user, utilize The drive of power set 41 is by support arm 42 and compresses arm 43 and is moved to place where wire rod, and now support arm 42 is understood at the bottom of wire rod Hold and compress arm 43 and can then compress and wire rod is pressed against under arm 43, furthermore, compress has on arm 43 on the top of wire rod One groove matched together in wire rod, the groove can more securely sandwiched wire rod, hereafter the power resources of wire rod will pass through this and one support The sandwiched of pressure arm 43 and support arm 42, more precisely, by support arm 42 and compress arm 43 back and forth reciprocally constantly by feeding Be open 22 end sandwiched wire rods, and the wire rod in front will continue to move forward, and reach the purpose of transmission.

Refer to shown in Fig. 5 and Fig. 6, wire rod is then persistently pulled along by clamping part 40, and by wear opening 24 from Open feeding track 22 and enter position and wear portion 50 wear the front of opening 24, and entrance is worn by the perforating 54 of the inlet face 52 Wear in portion's body 51, now, can clamp one positioned at the clamping arm 63 of exit face 53 and be intended to wear the tube of the wire rod by this Exit face 53 runs through into perforating 54, is vertebra shape due to the design of perforating 54 and is gradually inwardly tapered, the tubulose at the two ends Thing and wire rod can easily wear to enter and wear in portion's body 51, and because the aperture of perforating 54 is small, position is in the inner Persistently movement will run through into the tube to be run through the wire rod in portion, reach the purpose worn.

Refer to shown in Fig. 5 to Fig. 8, after the completion of tube is worn, clamping part 40 stops promoting wire rod, now fixed column 61 wire rods that can be pushed in feeding track 22 consolidate it, and then wearing portion's body 51 can be towards the direction for wearing opening 24 Mobile, the part for making tube be intersected with wire rod exposes to outside the portion of wearing 50 and exposes the unnecessary wire rod in a part of rear, connects The wire rod cutting for exposing this at this can be moved to by scissors 62, and clamping arm 63 just by tube and can be arranged inlet pipe The wire rod of shape thing is moved in the procedure of processing of next step, completes whole straightening, threading and the process blocked.

Described above is only preferred embodiment of the present utility model, not does any formal to the utility model Limitation, although the utility model is disclosed as above with preferred embodiment, but is not limited to the utility model, any ability The technical staff in domain, in the range of technical solutions of the utility model are not departed from, be able to should utilize in the technology of the disclosure above Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as without departing from technical solutions of the utility model Hold, any simple modification, equivalent variations and the modification made according to technical spirit of the present utility model to above example, still Belong in the range of technical solutions of the utility model.
