The automatic bending forming machine of net muscle
Technical field
The invention belongs to commercial facility processing equipment technical field, be specifically related to the automatic bending forming machine of a kind of net muscle, be used for net muscle bending and molding the net sheet the supermarket trolleys such as Openworks shape, shopping basket and the fruit thinning dish that constitute commercial facility.
Background technology
As be engaged in commercial facility exploitation and the industry of producing the reason of knowledge; Because it all is hollow out that self-selecting type supermarket, market are equipped with the structure of interim supermarket trolleys that uses and shopping basket etc. when supplying client's shopping goods usually; Particularly by the spacer screen sheet and net sheet all around and process, these net sheets are made up of the net muscle (also claiming rib) of specific standard usually.In manufacturing process, need to net muscle and be bent into " U " shape, " L " shape or " mouth " font or the like according to technological requirement, to be bent into U-shaped, prior art is often filled the post of with handwork by the workman.Specifically: fixed stop on operation post (industry is called stuck-module); In the time will bending to net muscle (typically having a diameter from 4-12 ㎜); The net muscle is placed in the groove between the adjacent blockers; Exhibition is rolled at the two ends that artificially will net muscle then in opposite directions, forming the shape of U-shaped, for the following process supermarket provides the technology assurance of preceding road with the net sheet of handcart, shopping basket etc.
Shortcoming below above-mentioned processing mode exists: the one, the degree of consistency of bending is difficult to ensure; Even if because same workman; Be difficult to objectively accomplish that the folding exhibition degree to each net muscle reaches unanimity, thereby influence the quality of subsequent technique, only if set up regularization treatment step; So that make the net muscle of each folding exhibition neat, but so way can increase processing step and manpower as one; The 2nd, the big and inefficiency of online assignment working strength of workers.
In view of above-mentioned prior art; If a kind of special-purpose machinery that can be suitable for the bending of net muscle is arranged; Foregoing problems just can solve so; Yet in disclosed patent and non-patent literature, all be not seen in the teachings that is able to use for reference, the applicant has done useful exploration for this reason, and the technical scheme that will introduce below produces under this background.
