Description

The handle builder

Technical field

The utility model belongs to metal iron wire bending and forming field of mechanical technique, be specifically related to a kind of handle builder, the material that being used for is shaped uses on coating barrel cage, pigment barrel cage, paint barrel cage, the container of daily life with barrel cage is the handle of metal iron wire

Background technology

Known, all be equipped with on the container that on be not limited to, exemplifies for holding and pinch the metal iron wire handle that lifts, the structure of this handle seems to be simple, but in order to satisfy intensity and corresponding mechanics requirement, therefore the shape of handle is comparatively special, be embodied in flex point and/or arc transition point is many, require comparatively harsh to forming technology.In addition, because handle belongs to nonstandard product, therefore can't obtain special-purpose former at commercially available channel.

At present, the shaping of above-mentioned handle is mostly relied on homemade mould bending by the workman, specifically fixes corresponding module at operation post, the metal iron wire that needs bending is placed in the groove between the adjacent block, artificially with the metal iron wire by the technological requirement bending.There are following 2 shortcomings at least in this operating type: one, it is the difficult quality guarantee that the degree of consistency of bending is difficult to ensure, even if because same operator, objectively can't accomplish the bending degree of metal iron wire is reached unanimity, again because manual bending and operator's experience, sense of responsibility and quality mind and even mood are closely related; Its two, the large and inefficiency of operator's labour intensity.In order to meet the need of market or to claim customer demand, the manufacturer that produces handle can only increase number of workers with passive mode, but because current work resource is very deficient and labor cost increases day by day, therefore cause product cost to show and increase, caused original comparatively cheap handle to lose the due market advantage.

Perhaps the someone can propose such query, since being exactly the handle of producing metal iron wire material, that has so shortcoming, can be replaced by the molded handle of plastics so fully, but, known reason, because there is poor, easy aging and fracture etc. the defective of load-bearing property in plastic handles, thereby can not satisfy the supporting requirement of aforementioned container.

Undoubtedly, if a kind of machinery that can be suitable for the automatic bending of metal iron wire handle of aforementioned applications occasion is arranged, just the problems referred to above are readily solved so.The applicant has carried out literature search for this reason, Chinese patent Granted publication CN101536878B recommends to have " household appliance handle and making mould and preparation method ", this patent scheme for be plastic handles, the metal iron wire handle that to be applied on the aforementioned container for being shaped does not have reference, especially because the handle that can only be shaped at every turn, therefore efficient is lower, is unfavorable for that industrial mass produces fast; Again, Granted publication CN202174179U provides " progressive die of pot lid handle ", and this patent structure is complicated and have a specific aim of the specific pot lid handle that namely can only be shaped, thereby does not have an enlightening significance for form metal iron wire handle; And, Granted publication CN202490885U introduces " a kind of U-shaped Bending Mould ", this patent can embody the strong point described in its specification the 0015th to 0019 hurdle, and once-forming go out a U-shaped workpiece (patent is shown and which kind of occasion workpiece is applied to) but for the shaping of metal iron wire handle and inapplicable, and owing to once can only obtain a U-shaped workpiece, so efficient is low; Also, Granted publication CN202199698U discloses to be had " apparatus for bending that the single compacting is how curved ", and this patent scheme can be applicable to the bending to steel wire, but equally for processing handle without reference value, and equally once can only obtain a workpiece, so efficient is lower; Again, " the net muscle automatic bending forming machine " of publication No. CN102172738A bulletin, CN102172739A " the net sheet automatic bending forming machine " announced and CN102172740A disclosed " net muscle automatic bending machine " all be for commercial facility such as self-selecting type supermarket, market be equipped with do shopping for client the time handcart of Interim use and shopping basket etc. the net sheet bending of Openworks shape.

In sum, be showed no all technology enlightenments for the reference of form metal iron wire handle in disclosed China and foreign countries' patent and the non-patent literature up to now, the applicant has done lasting and useful exploration and trial for this reason, finally find a way to resolve the problem, and formed technical scheme described below, especially, taked to have carried out simulated test in the applicant plant area under the strict secrecy provision through the applicant, it is practicable that the result proves
