Abstract
The utility model relates to a shearing mechanism of down-pipe cutting machine, in particular to the cutting device of the manufacturing process of the steel rectangular downpipe in building trade, which is the indispensable corollary equipment of the down-pipe. The shearing mechanism of down-pipe cutting machine is characterized in that the left and right piston rods are respectively installed on a cylinder for shear, and the left and right gears are respectively meshed with the rack bars and the left and right pushed knife holders, and the left and right cutting knives are respectively installed on the left and right pushed knife holders. The shearing mechanism of down-pipe cutting machine has the advantages of simple, compact and reasonable structure, stable and reliable performance, convenient installation, easy automation control, low cost, beautiful appearance, and small volume formed by closing all the device in a small space.
Description
Technical field
The utility model relates to the cutting mechanism on a kind of downpipe cutting machine, and specifically building trade is the indispensable corollary equipment of downpipe machine with the shearing device in the steel rectangular downpipe manufacture process.
Background technology
The steel downpipe is the indispensable auxiliary facility of steel building, and at present, it is direct-push that downpipe cutting machine cutting mechanism is sheared two oil cylinders, and oil cylinder exposes, and clamps four direction movement structure relative complex, and mechanism is huge, the manufacturing cost height, and profile is not attractive in appearance.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Volume is little, and low cost of manufacture is stable and reliable for performance, is easy to the downpipe cutting machine cutting mechanism of automation control.
Main solution of the present utility model is achieved in that
The utility model mainly adopts left and right sides piston rod 6,8 to be contained in respectively and shears on the oil cylinder 1, left and right sides gear 5,9 respectively with left and right sides piston rod 6,8 on tooth bar and about promote tool rest 4,7 engagements, promote on the tool rest 4,7 about left and right sides cutting knife 3,2 is installed in respectively.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; All mechanisms all are enclosed in the relatively little space, and volume is little, and low cost of manufacture is easy to install and use; The lines flow smoothly for outward appearance, elegant in appearance, stable and reliable for performance, is easy to automation control.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly by shear oil cylinder 1, left and right sides cutting knife 3,2, about promote tool rest 4,7, left and right sides piston rod 6,8, left and right sides gear 5,9 etc. and form.The axle of shearing oil cylinder 1, left and right sides gear 5,9 is fixed on the frame, adopt left and right sides piston rod 6,8 to be contained in respectively and shear on the oil cylinder 1, left and right sides gear 5,9 respectively with left and right sides piston rod 6,8 on tooth bar and about promote tool rest 4,7 engagements, promote on the tool rest 4,7 about left and right sides cutting knife 3,2 is installed in respectively.
Operation principle of the present utility model:
When workpiece need clamp shearing, shear oil cylinder 1B chamber oil-feed, piston rod 6 is to left movement, tooth bar on the left and right sides piston rod 6 and 5 engagements of left and right sides gear are rotated left and right sides gear 5, tooth bar engagement on left and right sides gear 5 and the left and right sides tool rest 4 promotes tool rest 4, push left-cut tool 3 to workpiece, surpass a half oil pocket A oil-feed when cutting off, cutting knife is return original position.And then oil pocket C oil-feed is pushed right-cut tool 2 to workpiece with cutting workpiece with identical principle, commutation at once after the cut-out, and D chamber oil-feed right-cut tool 2 is return original position.The fixing point of shearing oil cylinder 1, the rotary middle point of gear 5 are all on frame.Its whole process is control automatically all.
Claims (1)
1. the cutting mechanism on the downpipe cutting machine, comprise and shear oil cylinder (1), it is characterized in that adopting left and right sides piston rod (6,8) to be contained in respectively and shear on the oil cylinder (1), left and right sides gear (5,9) respectively with left and right sides piston rod (6,8) on tooth bar and about promote tool rest (4,7) engagement, promote on the tool rest (4,7) about left and right sides cutting knife (3,2) is installed in respectively.
