The advantage that novel clutch and brake plate shearing machine of the present utility model has: clutch brake is simple in structure in the complete machine, especially this clutch brake merges into a single whole clutch and brake, existing transmission clutch function, can play braking function again, upper tool post is stopped on the dead-centre position exactly.Therefore, complete machine structure novelty, compactness, little, the good looking appearance of volume, operating maintenance is convenient, low cost of manufacture, remarkable in economical benefits.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is novel clutch and brake plate shearing machine structural representation;
Fig. 2 is a drive mechanism schematic diagram among Fig. 1;
Fig. 3 is clutch brake 11 structural representations among Fig. 2;
Fig. 4 is L fork 14 structural representations among Fig. 3.
Shown in Fig. 1 to 4, this machine gear 2 is made up of one pair of belt pulley 18a, 18b pinion 19 and output wheel 20, and after motor 1 started, motor 1 drove belt pulley 18, pinion 19 and output wheel 20.After electromagnet 26 energisings, electromagnet 26 overcomes the pulling force of push rod spring 25, push rod 24 separates with L fork 14, L fork 14 is subjected to the pulling force of extension spring 23, L fork 14 rotates to round platform 21 fan grooves one side on the clutch and brake eccentric wheel 12, L fork 14 end sides meniscus level corner angle change in the clutch circle 13 on the nose circle faces in the breach, the output wheel 20 of rotation L fork 14 on clutch circle 13 drives clutch and brake eccentric wheel 12, power transmission shaft 10, eccentric wheel 9a, 9b, connecting rod 8a, 8b, make shear beam 6 along wallboard 5a, 5b upper rail groove moves up and down, cutter 7 on the shear beam 6 and bottom knife 4 relative motions on the workbench 3 are sheared plate.After electromagnet 26 outages, push rod 24 is subjected to the pulling force of push rod spring 25, push rod 24 resets, push rod 24 withstands L fork 14 on the clutch and brake eccentric wheel 12, L fork 14 overcomes extension spring 23 pulling force and rotates to clutch and brake eccentric wheel 12 round platforms 21 fan groove opposite sides, L fork 14 end sides meniscus level corner angle withdraw from breach on the clutch circle 13 interior nose circle faces, slide along annular chutes in the clutch circle on output wheel 20 sides 13.Above-mentioned clutch and brake eccentric wheel 12 loses driving force, transmission eccentric wheel 12 outer ring flanges are more and more far away at a distance of keeper 17,16 pairs of clutch and brake eccentric wheel 12 brake force of brake band also strengthen gradually, until hugging clutch and brake eccentric wheel 12 fully, shear beam 6 accurately stops on the top dead-centre, can stop to shear plate.In order to guarantee that shear beam 6 is accurately stopping at peak, regulate brake band 16 and clutch and brake eccentric wheel 12 degrees of tightness easily, elastic limit device 22 is housed on the above-mentioned keeper 17 to be made up of gag lever post 28, stage clip 29, be equipped with convex shoulder in the middle of the gag lever post 28, the slide opening that gag lever post 28 1 ends pass on the keeper 17 is connected with brake band 16, the other end is with stage clip 29, stage clip 29 1 end apical grafting keepers 17, its other end and the bolt apical grafting that is packed in gag lever post 28 other ends.
