To improve the work efficiency of machine of breaker plate punching, reduce worker labor intensity and safe production, be necessary to use send makings orgnaization automatically. But the punching machine to different specifications, produce the product of different specifications, choose send makings unit differently, to managing cost, rise send makings precision to wait to have differ significantly. Common is to resemble more " equipment management and maintenance " 2002 6 period the installs rack on press slide block method of intermediary carry on. But to in small tonnage press is strong make the breaker plate with lesser dimension, use following structures send makings unit more simple, and send makings precision to be able to be amounted to 0.

02mm above, the installation that make is easy. Main structure sketch map sees this unit the graph is shown 1 times. The first line of a couplet on a scroll is added to receive an axis in a side of compressor eccentric shafe, remaining part of swallow of mount of chamfer of one swallow end opens in the end panel of connection axis piece, swallow end piece OK inside groove adjustment, join with the articulatory bearing of connecting rod one aspect of the matter. The articulatory bearing of connecting rod other one aspect of the matter and clip makings orgnaization place a photograph mediumly to join (graph 2) . Nextpage shows clip 2 times to expect the orgnaization is medium in the graph, because compress the action of bedspring to make go up,press roller to press feeding roller closely, place at the same time piece drive feeding roller roll through pawl, come true thereby send makings movement. Should send makings device automatically main component reach connecting rod for ratchet, feeding roller. Feeding roller diameter and number of spine teeth of a cogwheel are decided by breaker plate pitch, if breaker plate pitch is D, ratchet normally but preelection tine counts Z=12, modulus M=6mm, criterion π of ／ of D=dz of feeding roller diameter, of the edge on requirement feeding roller and punch lower mould on plane is in same plane to go up, otherwise, adjust spine teeth of a cogwheel to count, until accord with a requirement till. If the graph shows three-dimensional picture 3 times,this structure can be made, α is axes of press eccentric shafe and the around distance that place a center, b is the distance of vertical plane of feeding roller axes to connection axis end panel, to send makings axis the vertical distance of center and eccentric shafe center. The computational formula that can reach connecting rod grows L is: As a result of articulatory bearing and swallow the eccentric throw R of end piece is adjustable, r=0 can be set when computation, go up thereby type can simplify for: As a result of connecting rod the articulatory bearing of two end is adjustable, additional swallow end piece eccentric throw is adjustable, place horny α consequently adjustable also inside bigger range, thereby the requirement of dimension of connecting rod L but need not too accurate.
