Abstract
A rounding machine for the oblique ribs of anchor rod made of screw-thread steel is composed of a main body with clamping unit and rounding unit on it bench, a power drive system, and a controller. Said rounding unit consists of horizontal cylinder and rounding die installed to the piston of horizontal cylinder.
Description
Technical field
The invention belongs to screw-thread steel surface diagonal rib and remove equipment, be specially adapted to the equipment that twisted steel anchor rod is removed surperficial diagonal rib before processing afterbody standard thread.
Background technology
Twisted steel anchor rod is widely used in the coal mine support.The twisted steel anchor rod afterbody must be removed body of rod surface diagonal rib earlier before rolled thread.At present the diagonal rib removal method of using has three kinds of turning methods, hot rammer method, cold rolling circule method.The turning method be with lathe cut away surperficial diagonal rib, production efficiency is low, labour intensity is big, easily off-centre and working position have step to make anchor pole mechanical property variation; What use was maximum at present is cold rolling circule method, and it is that the employing cold-rolling mill two pair of rollers screw-thread steel bodies of rod carry out the line contact, open moving reciprocatingly is pressed into body of rod surface diagonal rib in the body of rod.But the shortcoming that this method exists is: the rounding position easily produces bending, needs manually to carry out straightening again, and is bigger to the following process device damage; Cold rolling contact-making surface inwardly shrinks, and former contact-making surface outwards is out of shape, and causes the screw-thread steel material loose through back and forth pushing several times, and body anchor pole mechanical property reduces, and has hidden danger; Circularity is bad, and surface quality can not guarantee.
Summary of the invention
The purpose of this invention is to provide the surface of a kind of twisted steel anchor rod before the processing of afterbody standard thread and tiltedly help the rounding machine, once surperficial diagonal rib is pressed in the body of rod easily, reach the purpose of rounding.
The realization the technical solution adopted in the present invention is:
A kind of twisted steel anchor rod inclined rib round rectifying machine, it comprises body, power-driven system, control device, it is characterized in that device has the clamping device of the screw-thread steel that is fixedly clamped and the rounding device of removal screw-thread steel surface diagonal rib on the upper table surface of body; Upper grip on vertical oil cylinder piston of vertical oil cylinder, device, the lower chuck that is fixed on the body by locating piece are formed the screw-thread steel clamping device; Cross cylinder and the rounding mould of device on the cross cylinder piston are formed the rounding device, and the rounding die head that the rounding mould is fixed on the fixed cover front end by fixed cover, by locking cap is formed; The circular hole at fixed cover, locking cap center is all greater than rounding die head centre bore; The center-hole diameter of rounding die head equals twisted steel anchor rod body of rod diameter; Rounding device guiding plate is housed in the one or both sides of rounding device: rounding die head hardness is greater than the hardness of twisted steel anchor rod.
A semicircle clip slot is respectively arranged on described upper grip and the lower chuck, have on the clip slot inwall with screw-thread steel on the corresponding groove of diagonal rib so that improve the clamping effect.
The centre bore two ends of described rounding die head are provided with lead angle.
During use, screw-thread steel one end is clamped in the clip slot on the clamping device, and stretch out suitable length, start hydraulic power system, the vertical hydraulic oil cylinder clamps the body of rod, the horizontal hydraulic pressure oil cylinder piston travels forward then, the rounding die head entangles the screw-thread steel section of stretching out termination and travels forward along screw-thread steel body of rod axis, because rounding die head hardness is greater than screw-thread steel hardness, therefore produce the circumference restraining force of warp-wise at double thread steel of proal while of rounding die head, screw-thread steel surface diagonal rib can be pressed in the body of rod, reach the rounding purpose; Cross cylinder piston band the rounding mould and is moved backward after rounding length reaches requirement, until withdrawing from the screw-thread steel body of rod, unclamps clamping device, finishes a production cycle.
The invention has the beneficial effects as follows: technology is simple, once just can reach the rounding effect, and labor strength is low, the production efficiency height.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is rounding mode structure figure;
