The utility model discloses a realize through following technical scheme:
an adjustable steel bar shearing machine comprises a rack, a fixed knife rest fixedly arranged on the rack, an upper blade fixedly arranged on the fixed knife rest, a driving oil cylinder, a movable knife rest, a lower blade fixedly arranged on the movable knife rest, and a guide adjusting device, wherein the end part of a piston rod of the driving oil cylinder is hinged with the movable knife rest to drive the movable knife rest to move left and right, two sides of the rack are respectively provided with a rack adjusting hole, the two guide adjusting devices respectively comprise a guide rail, a transverse adjusting jackscrew, a vertical adjusting jackscrew, a transverse adjusting plate and a vertical adjusting plate, the guide rail is of a groove-shaped structure and comprises a guide rail bottom plate and two guide rail side plates, the guide rail bottom plate is fixedly arranged on the side surface of the rack, the middle part of the guide rail bottom plate is provided with a bottom plate threaded hole, the transverse adjusting jackscrew is, the lateral plate threaded holes are formed in the guide rail lateral plates below, the vertical adjusting jackscrews penetrate through the lateral plate threaded holes, the vertical adjusting plates are fixedly installed at the end parts of the vertical adjusting jackscrews, and the two sides of the movable knife rest are arranged between the transverse adjusting plate and the vertical adjusting plate of the two guide rails.
Furthermore, wear-resistant lining plates are respectively and fixedly arranged on the transverse adjusting plate, the vertical adjusting plate and the side plates on the guide rail.
Furthermore, a plurality of frame adjusting holes are formed in two sides of the frame.
The beneficial effects of the utility model
The utility model provides a pair of adjustable bar shear, through adjusting the knife rest position come the compensation because of the cutting edge clearance increase volume that wearing and tearing produced, make the clearance of upper and lower cutting edge keep at the within range of regulation, make the shearing action stable simultaneously, avoid moving the knife rest swing.
Drawings
Fig. 1 is a schematic top view of the present invention;
FIG. 2 is a schematic view of the structure of the present invention;
in the figure, 1, a rack, 2, a driving oil cylinder, 3, a guide rail, 4, a movable knife rest, 5, a lower blade, 6, an upper blade, 7, a fixed knife rest, 8, a transverse adjusting jackscrew, 9, a rack adjusting hole, 10, a vertical adjusting plate, 11, a vertical adjusting jackscrew, 12, a transverse adjusting plate and 13, a wear-resistant lining plate are arranged.
Detailed Description
An adjustable steel bar shearing machine comprises a frame 1, a fixed cutter rest 7 fixedly arranged on the frame, an upper blade 6 fixedly arranged on the fixed cutter rest, a driving oil cylinder 2, a movable cutter rest 4, a lower blade 5 fixedly arranged on the movable cutter rest and a guide adjusting device, wherein the end part of a piston rod of the driving oil cylinder is hinged with the movable cutter rest to drive the movable cutter rest to move left and right, two sides of the frame are respectively provided with a frame adjusting hole 9, the two guide adjusting devices respectively comprise a guide rail 3, a transverse adjusting jackscrew 8, a vertical adjusting jackscrew 11, a transverse adjusting plate 12 and a vertical adjusting plate 10, the guide rail is of a groove-shaped structure and comprises a guide rail bottom plate and two guide rail side plates, the guide rail bottom plate is fixedly arranged on the side surface of the frame, the middle part of the guide rail bottom plate is provided with a bottom, horizontal regulating plate fixed mounting has seted up the curb plate screw hole in horizontal regulation jackscrew tip on the guide rail curb plate below, and vertical regulation jackscrew passes the curb plate screw hole, vertical regulating plate fixed mounting is in vertical regulation jackscrew tip, and the both sides of moving the knife rest are located between the horizontal regulating plate and the vertical regulating plate of two guide rails.
Furthermore, wear-resistant lining plates 13 are fixedly mounted on the lateral plates on the transverse adjusting plate, the vertical adjusting plate and the guide rail respectively, so that the wear resistance of the device is improved, and the service lives of the guide rail, the transverse adjusting plate and the vertical adjusting plate are prolonged.
Furthermore, a plurality of frame adjusting holes are formed in the two sides of the frame, and the installation position of the guide adjusting device can be adjusted according to the diameter of the shearing reinforcing steel bar.
When the steel bars need to be sheared, the steel bars are placed between the upper blade and the lower blade, the oil cylinder drives the movable knife rest to move along the guide rail in the direction of the upper blade, and the lower blade is matched with the upper blade to cut off the steel bars. The movable knife rest and the guide rail are in relative motion, so that abrasion can occur, when the side surface of the movable knife rest is seriously abraded, the transverse adjusting jackscrew is rotated, the transverse adjusting plate moves forwards to jack the side surface of the movable knife rest to realize side surface compensation, when the bottom surface of the movable knife rest is seriously abraded, the vertical adjusting jackscrew is rotated to enable the vertical adjusting plate to move upwards to jack the side surface of the movable knife rest to realize bottom surface compensation, so that the gap between the lower blade and the upper blade is adjusted, the gap between the upper blade and the lower blade is kept in a specified range, meanwhile, the shearing action is stable, and the swinging of the movable knife rest is avoided.
To sum up, the utility model provides a pair of adjustable bar shear through adjusting the removal knife rest position, can compensate because of the cutting edge clearance increase volume that wearing and tearing produced, makes the clearance of upper and lower cutting edge keep at the within range of regulation, makes the shearing action stable simultaneously, avoids removing the swing of knife rest.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
