Abstract
The present invention relates to a composite precise bar material shearing machine and a composite shearing method thereof. The composite precise bar material shearing machine comprises a composite shearing depth adjusting part, a clamping and shearing part, a pushing, clamping and loosening part, and a crank composite shearing part. Because the present invention adopts a composite shearing method, bar materials are sheared after being clamped by an upper cutter and a lower cutter. Because of being clamped by the upper cutter and the lower cutter, the bar materials can not bend during shearing. Therefore, the bar materials almost have no compression degree, and shearing sections are relatively vertical. The preshearing depth of the product is about from 1/3 to 3/4 of the shearing depth. When preshearing is finished, a slide block runs towards a reverse direction and enters a shearing area, so the bar materials can be superposed with the preshearing area easily. Therefore, the shearing sections are vertical, and the core parts of the bar materials can not be torn.
Description
The present invention relates to compound cutting machine of a kind of bar and combination shearing method thereof.
Carrying out sheared blank at present both at home and abroad all is to adopt unidirectional cutting method, and shearing section flattening degree is big, and non-perpendicularity is big, and the bar core is torn phenomenon, influences quality and next procedure.
The purpose of this invention is to provide a kind of compound cutting machine of bar and combination shearing method thereof that adopts combination shearing method to shear bar.
For achieving the above object, technical scheme of the present invention is: the compound cutting machine of a kind of bar, comprise combination shearing degree of depth adjustment member, clamp and cutting out section, promote to clamp and unclamp part, crank combination shearing part, it is characterized in that: adjust wedge (2) and be installed on the slide block (1) by guide rail, deciding wedge (3) is fixed on the framework (4), bottom knife (5) is fixed on the framework (4), cutter (6) is fixed on the small slide block (15), small slide block (15) is connected on the framework (4) by guide rail, deciding wedge (7) is fixed on the small slide block (15), moving wedge (8) is connected by guide rail to be decided on the wedge (7), tooth bar (9) is fixed on the moving wedge (8), tooth bar (11) is fixed on the moving wedge (12), moving wedge (12) is connected by guide rail to be decided on the wedge (13), decides wedge (13) and is fixed on the framework (4), and crank (14) is contained in the quadrel (16), quadrel (16) is contained in the square hole of slide block (1), and gear (10) is contained on the support of framework (4).Its combination shearing method is: at first rotated by gear (10) up time, drive and decide wedge (8), moving wedge (12) upper and lower displacement, move to left and promote small slide block (15), simultaneously framework (4) has trace to move to right bar is clamped, when crank (14) inverse time direction rotating band movable slider (1) moves to right, at first pass through transition gap (17) afterwards, slide block (1) moves to right, driving framework (4) moves to right, rotate to 0 °, the pre-shearing ended, when crank (14) rotation by 0 ° when being rotated counterclockwise for 180 °, then that sheared blank is disconnected.
The present invention is because of adopting combination shearing method, bar is sheared after upper and lower cutter clamps, because of upper and lower cutter clamps, bar is not crooked when shearing, because of so the not crooked bar of bar does not almost have the flattening degree, so the shearing section is more vertical, be the double direction shear structure because of adopting combination shearing in addition, the preshearing degree of depth is about the shearing degree of depth of 1/3-3/4, and when pre-shearing end of a period, slide block is to reverse direction operation, then enter and cut off the zone, bar is easily overlapped along the share zone of preshearing,, and the bar core is not torn so the shearing section is vertical.
Fig. 1 is a structural representation of the present invention.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further: the compound cutting machine of bar, comprise combination shearing degree of depth adjustment member, clamp and cutting out section, promote to clamp and unclamp part, crank combination shearing part, it is characterized in that: adjust wedge 2 and be installed on the slide block 1 by guide rail, deciding wedge 3 is fixed on the framework 4, bottom knife 5 is fixed on the framework 4, cutter 6 is fixed on the small slide block 15, small slide block 15 is connected on the framework 4 by guide rail, deciding wedge 7 is fixed on the small slide block 15, moving wedge 8 is connected by guide rail to be decided on the wedge 7, tooth bar 9 is fixed on the moving wedge 8, and tooth bar 11 is fixed on the moving wedge 12, and moving wedge 12 is connected by guide rail to be decided on the wedge 13, deciding wedge 13 is fixed on the framework 4, crank 14 is contained in the quadrel 16, and quadrel 16 is contained in the square hole of slide block 1, and gear 10 is contained on the support of framework 4.Its combination shearing method is: during combination shearing, different by the bar material with diameter, it is also different that it shears the degree of depth, in order to adjust the preshearing degree of depth, partly be provided with one group in preshearing and adjust wedge 2 and decide wedge 3,, then increase the preshearing degree of depth when adjusting skewback 2 to rise, then reduce the preshearing degree of depth to downward modulation, adopt the scissors clamping device for bar is not tilted in shear history, at first gear 10 up times rotation during clamping drives and decides wedge 8, moving wedge 12 upper and lower displacements, move to left and promote small slide block 15, framework 4 moves to right bar is clamped simultaneously, when 14 inverse time of crank direction rotating band movable slider 1 moves to right, at first passes through after the transition gap 17, slide block 1 moves to right, drive framework 4 and move to right, rotate to 0 °, the pre-shearing ended, when crank 14 rotation by 0 ° when being rotated counterclockwise for 180 °, then that sheared blank is disconnected.
