Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1;
Fig. 3 is A direction view in figure A.
Detailed description of the invention
The axis of round steel when " longitudinal direction " in the utility model refers to vertical stationary knife, round steel is sheared in moving knife knife face direction namely, the above-below direction namely in Fig. 2, " transverse direction " refers to the left and right directions in stationary knife, the knife face direction of moving knife i.e. Fig. 2.
The bar cutting-off machine that the shearing force of the present embodiment is adjustable, as shown in Figure 1: comprise frame 1, frame 1 is provided with stationary knife 2 and moving knife 3, moving knife 3 all has with the opposite side of stationary knife 2 half slot adapted with round steel to be cut, round steel 100 is delivered in the half slot of stationary knife 2 by pay-off, and stationary knife 2 and moving knife 3 are arranged on stationary knife seat 6 and moving knife seat 4 respectively.Moving knife seat 4 can frame 1 slide up and down relatively, and frame 1 is provided with depress oil cylinder 200 and moves back and forth to drive moving knife seat 4 and moving knife 3 as transmission mechanism.
As shown in Figure 2, moving knife seat 4 having longitudinal chute 401, moving knife 3 longitudinal sliding motion in longitudinal chute 401, moving knife seat 4 being also provided with for vertically moving moving knife 4 to adjust the clearance adjustment mechanism 5 of itself and stationary knife 2 axial clearance.
Clearance adjustment mechanism 5 can be that cylinder isoline output mechanism directly longitudinally acts on moving knife 4, although its structure is simple, but will the longitudinal length of frame be increased, and the lateral dimension of frame entirety is greater than its longitudinal size, the increase of such longitudinal size will increase the spatial volume shared by Whole Equipment greatly.For this reason, the utility model is established and is provided a kind of and occupy the less clearance adjustment mechanism of longitudinal space, it comprises tiltedly carves 501 and cylinder 502, moving knife seat 1 also has the horizontal concrete chute 402 communicated with longitudinal chute 401, tiltedly carve contact of incline plane between 501 and moving knife 3, cylinder 502 drive tiltedly carve 501 in horizontal concrete chute 402 transverse shifting.Tiltedly carve 501 and drive transverse shifting in horizontal concrete chute 402 by cylinder 502, the relative one side away from stationary knife 2 of moving knife 3 is inclined-plane, tiltedly carve 501 to contact with the inclined-plane of moving knife, both form Xie Qie mechanism, tiltedly carving 501 transverse shiftings makes moving knife 3 vertically move, such stationary knife 2 and moving knife 3 and between gap adjustable, within the specific limits, can cut the round steel of different intensity, simultaneously, this clearance adjustment mechanism 5 mainly utilizes horizontal space to arrange, occupies less longitudinal space, makes Whole Equipment small volume.
Meanwhile, stationary knife seat 6 bottom end is hinged by bearing pin 7 and frame 1, and the other end of stationary knife seat 6 is driven by swing mechanism 8 and stationary knife seat is swung up and down around bearing pin 7.The swing of stationary knife seat 6 is positioned at and has been driven by swing mechanism, the application point of swing mechanism to stationary knife seat 6 is positioned at the other end of relative bearing pin 5 on stationary knife seat 6, this swing mechanism comprises slide 801, slide bar 802, connecting rod 803, slide 801 is provided with gathering sill 804, slide bar 802 slides up and down for being directed at gathering sill 804, connecting rod about 803 two ends respectively with stationary knife seat 6 and slide bar 802 hinged, as illustrated by the arrows in fig. 1, slide bar 802 slide downward, stationary knife seat 6 and stationary knife 2 counter-clockwise swing can be driven by connecting rod 803, and then make the relative moving knife 3 of stationary knife 2 tilt adjustable, so just can according to the round steel of varying strength, adjust different stationary knife angles of inclination, namely the size of shearing force is adjusted.
Slide bar 802 has screw thread 805, be combined with screw thread 805 and move axially confined swivel nut 806, sliding up and down of slide bar 802 can be converted into by the rotation of swivel nut 806.Concrete, the rotation of swivel nut 806 has been driven by swing arm 807 and oscillating cylinder 808, wherein one end of swing arm 807 is placed on outside swivel nut 806, the other end is driven by oscillating cylinder 808, as shown in Figure 3, swivel nut 806 can be driven to rotate by the swing of swing arm 807, swing arm 807 have upper lower baffle plate and move axially to limit swivel nut 806.
