Description

A kind of self-return feed mechanism with anti-feed back function
Technical field
The utility model relates to mould material belting technical field, in particular to a kind of self-return feed mechanism with anti-feed back function.
Background technology
At present, a lot of small-sized five metals element was all exist with the form of material strip before follow-up assembling, and pressed part is mainly attached on material strip by progressive die material strip, in the mode of equidistant feeding, semi-finished product was delivered to punching press on each engineering station and cut.The every punching press of mould completes once, and material strip fixed-distance moving once, completes to product, and progressive die material material strip in punching course moves to a direction all the time.The general object adopting artificial pusher to reach friction feeding now, production efficiency is low; The employing autoloader also had, its complex structure, and also cost is higher.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, promotes the self-return feed mechanism with anti-feed back function of material strip fixed-distance moving continuously, to solve the problem.
For realizing the utility model object, the technical scheme of employing is: a kind of self-return feed mechanism with anti-feed back function, and comprise two the shifting block groups arranged along feeding channel, one of them is fixedly installed, and another is connected with the drive unit driving it to slide; Each shifting block group comprises pusher shifting block and slide block, and pusher shifting block comprises hinged end and material toggling end, hinged end by rotating shaft and slide block hinged, material toggling end is provided with lead-in chamfered; The top of pusher shifting block is provided with boss, slide block is provided with the confined planes contacted with boss end face; Rotating shaft is positioned at the side of being partial to material toggling end in the middle part of boss; Stage clip is connected with between the top of pusher shifting block and the confined planes of slide block.
The shifting block group arranged by sliding carries out the promotion feeding of material strip, rotating shaft and the centre of gyration, it is positioned at the side of being partial to material toggling end in the middle part of boss, pusher shifting block one direction is rotated, namely when pusher shifting block pusher, edge, boss rear is against on confined planes and pusher shifting block can not be rotated, and material strip passes through this material toggling group be fixedly installed by the lead-in chamfered of another fixing pusher shifting block, and the pusher shifting block of now fixing material toggling group upwards rotates and material strip is passed through; When pusher shifting block pushes return after certain distance, tape surface is slipped over by the guiding of lead-in chamfered, simultaneously, because the edge, front of boss is just the radius of gyration, pusher shifting block can be made upwards to rotate around the shaft, stage clip is compressed, pusher shifting block enters next material strip gap through tape surface, pusher shifting block is rotated down around the shaft to original position under stage clip recovers the active force of former length, and namely boss end face contacts with confined planes, carries out the propelling movement next time of material strip; When pusher shifting block return, the material toggling end of the shifting block group be fixedly installed can prop up material strip, prevents its pusher shifting block of following slip setting from sliding together and occurs feed back phenomenon.
Further, described drive unit is cylinder, and the slide block in a shifting block group is connected with cylinder.
Further, the bottom of described slide block offers groove, and pusher shifting block is positioned at groove, and the groove bottom of groove is confined planes.
Further, hinged end and boss are positioned at same one end of pusher shifting block, and material toggling end is the other end corresponding thereto.
Further, described material toggling end arranges material toggling tooth, and the lower end of material toggling tooth is pointed, and lead-in chamfered is positioned at the side of the close boss of material toggling tooth.
The beneficial effects of the utility model are, the slide block arranged by sliding drives pusher shifting block by material strip pushed forward, confined planes restriction boss makes pusher shifting block can not rotate under the reaction force of material strip, after pushing certain distance, during slide block drive pusher shifting block return, pusher shifting block rotates up around the shaft and realizes return, so by the control of drive unit, slide block is reciprocatingly slided to realize promoting material strip fixed-distance moving continuously, simultaneously by the fixing anti-stopping materials strip feed back of shifting block group, structure is simply effective, cost is low, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation with the self-return feed mechanism of anti-feed back function that the utility model provides;
Fig. 2 is the decomposing schematic representation in the self-return feed mechanism of anti-feed back function with the shifting block group arranged of sliding that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the self-return feed mechanism with anti-feed back function that the utility model provides, and comprise two the shifting block groups arranged along feeding channel 7, one of them is fixedly installed, and another is connected with the drive unit driving it to slide; Each shifting block group comprises pusher shifting block 1, slide block 2 and is connected the drive unit 3 driving it to slide with slide block 2; Pusher shifting block 1 comprises hinged end 11 and material toggling end 12, and hinged end 11 is hinged by rotating shaft 5 and slide block 2, and material toggling end 12 is provided with lead-in chamfered 13; The top of pusher shifting block 1 is provided with boss 4, slide block 2 is provided with the confined planes 21 contacted with boss 4 end face; Rotating shaft 5 is positioned at the side of being partial to material toggling end 12 in the middle part of boss 4; Stage clip 6 is connected with between the top of pusher shifting block 1 and the confined planes 21 of slide block 2.
Drive unit 3 is cylinder, also can be the drive units such as hydraulic cylinder, and the slide block in a shifting block group is connected with 2 cylinders.During use, be arranged on the delivery track of material strip by this feed mechanism, cylinder is fixed on delivery track is with movable slider to move back and forth, and in Fig. 1, arrow is the conveying material toggling direction of material strip.
The bottom of slide block 2 offers groove 22, and pusher shifting block 1 is positioned at groove 22, and the groove bottom of groove 22 is confined planes 21.Hinged end 11 and boss 4 are positioned at same one end of pusher shifting block 1, and material toggling end 12 is the other end corresponding thereto.Material toggling end 12 arranges material toggling tooth 14, and the lower end of material toggling tooth 14 is pointed, is more convenient to stir material strip, and lead-in chamfered 13 is positioned at the side of the close boss 4 of material toggling tooth 14.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
