Description
Technical field
The utility model is about a kind of section bar shearing equipment, relates in particular to a kind of Double Dimension Flying Shears swinging blade clearance adjusting device.
Background technology
Flying shear blade sideshake adjusting device is to produce sideshake by allowing between two cutting edges, makes shearing equipment when rolled piece is sheared, and neither can collide mutually, also can not cause the out-of-flatness of rolled piece shearing area because of blade clearance is excessive.
Existing flying shear blade sideshake adjusting device is a wedge lock washer adjusting device, shown in Fig. 4 A, Fig. 4 B, the lower end bent axle 911 of crank axle 91 connecting portions wears in the fixed shaft hole 941 that is fixed on circular cutter holder 94 bottoms, the top 942 of circular cutter holder 94 is positioned at the upper end 912 of crank axle 91 connecting portions by positioning sleeve 92, is fastened on the crank axle 91 with bolt 93 again; Cutting edge 97 is fastened to the lower end (being provided with pad 98 between the lower end of cutting edge 97 and circular cutter holder 94) of circular cutter holder 94 by bolt 99, by wedge 95 and screw 96 it is locked again; When rotating shaft 913 driven-mechanisms of crank axle 91 drive when rotating, can drive circular cutter holder 94 and cutting edge 97 and rotate together, two circular cutter holders 94 that are oppositely arranged and cutting edge 97 are sheared rolled piece in relative rotary course.Because the sideshake of two cutting edges 97 should be 0mm under theoretical situation,, in order to allow two cutting edges 94 produce sideshake, need process here pad 98, make its thickness attenuation, produce sideshake thereby make between two cutting edges 97.Though this method can effectively be adjusted blade clearance, has, and has following shortcoming:
1. cutting edge 97 is changed frequent (an about week is changed once), and needs to adjust blade clearance after changing; And when relieving, changing the rolled piece specification, all need to adjust blade clearance; When adjusting blade clearance, need earlier screw 96 to be unclamped, take off wedge 95, then bolt 99 is unclamped, take out pad 98 and process, will grind good pad 98 and cutting edge 97 afterwards again and be fastened on the circular cutter holder 94, increased the needed time of adjustment blade clearance so greatly.
2. when adjusting blade clearance, bolt 99 need be unclamped, and bolt 99 is for the specific Tightening moment of the fastening needs of cutting edge, if frequent assembling-disassembling bolt 99, at first be to the screw thread of bolt 99 frequent cause load, the life-span of bolt 99 can reduce greatly; Next is owing to need guarantee the Tightening moment of bolt 99 when fastening bolt 99, so if during fastening bolt, Tightening moment does not reach setting value, flying shear abnormal sound can occur when shearing, and under the serious situation, can cause bolt 99 fractures.
In view of this, the inventor relies on relevant design and manufacturing experience for many years, proposes a kind of Double Dimension Flying Shears swinging blade clearance adjusting device, to overcome the defective of prior art.
