Metal material saw cutting device of the present utility model, during work, down pressing oil cylinder and clamping cylinder can be counted time and the distance of recording out propelling after advancing clamping work pieces, according to this parameter, determine the size of the sectional area that workpiece is sawed, thereby best revolution and the optimum feed speed of by control device, being determined saw disc, this apparatus structure is simple, and flexible movements are reliable, improve operating efficiency, extended the service life of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the perspective view of the frame shown in Fig. 1, transfer roller mechanism, down pressing oil cylinder, guide post, clamp portion.
The specific embodiment
As shown in Figure 1, 2: 21 is frame, the 20th, the transfer roller mechanism matching with frame 21.At the middle part of transfer roller mechanism 20, be provided with and support by the work top 19 of cut part 18.There is saw disc gap at the middle part of work top 19, in this saw disc gap, is provided with saw disc 17, and saw disc 17 is rotatably connected on support 4 by saw disc axle 1.
Saw disc axle 1 connects the power transmission shaft 5 being supported on support 4, and one end of power transmission shaft 5 is fixedly connected with driving bevel gear 3, and the termination of saw disc axle is fixedly connected with the driven bevel pinion being meshed with driving bevel gear 3.Power transmission shaft 5 other ends connect driving mechanism by shaft coupling 6, and this driving mechanism comprises decelerator 9 and motor 10, and the power shaft of the output shaft of motor 10 and decelerator 9 joins, and the output shaft of decelerator 9 connects power transmission shaft 5 by shaft coupling 6.
Support 4 belows are fixedly connected with movable plate 8, between movable plate 8 and frame 21 for being slidably connected.Movable plate 8 is access to and returns pushing mechanism, reciprocating mechanism comprises the Shift cylinder 11 being fixedly connected in frame 21, the piston rod external end head joining with Shift cylinder 11 connects contiguous block 2, contiguous block 2 joins with movable plate 8, during Shift cylinder 11 action, can drive movable plate 8 to move with respect to frame 21, support 4 moves thereupon.
On the upper methods, rack 21 of work top 19, be provided with upper beam 15, upper beam 15 is provided with down pressing oil cylinder 13, the piston rod external end head matching with down pressing oil cylinder 13 is connected with pressing plate 16, and pressing plate 16 is connected with guide post 14, and the sliding sleeve matching with guide post 14 is fixed on upper beam 15.
In frame 21, be provided with the clamping cylinder 12 that horizontal direction arranges.
Upper beam 15, down pressing oil cylinder 13, guide post 14, pressing plate 16 are two groups and are separately positioned on the both sides in work top 19 saw disc gaps, top.
It is that the time relay and advance distance detecting element are straight line coding device that down pressing oil cylinder 13, clamping cylinder 12 are all furnished with the propelling time detecting element joining with controlling organization.While making down pressing oil cylinder 13, clamping cylinder 12 action, can measure out clamping work pieces propelling time and advance distance before, and controlling organization is determined by the sectional area of cut part according to this parameter, thereby determine the revolution of the motor 10 that drives saw disc 17 rotations, the final revolution of determining that saw disc 17 is own, determine the feed speed of Shift cylinder 11 simultaneously, finally determine the feed speed that saw disc 17 is own.This apparatus structure is simple, and flexible movements are reliable, has improved operating efficiency, has extended the service life of equipment.
