Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the embodiment provides an automatic material transferring machine, which includes a workbench 1, a saddle 2, a sliding device 3 and a driving device 4; the saddle 2 generally comprises two upright posts 21 and a cross beam 22, wherein the upright posts 21 are generally integrally formed with the workbench 1 or welded to the workbench 1, the upper parts of the upright posts 21 are provided with semicircular grooves, and the cross beam 22 is erected on the semicircular grooves.

The sliding device 3 comprises a first hydraulic cylinder 31 and a first support 32, the axis of the first hydraulic cylinder 31 is perpendicular to the cross beam 22, the cylinder body of the first hydraulic cylinder 31 is fixedly arranged on the workbench 1 through a U-shaped clamp and a bolt, a steel plate is welded on a first piston rod 311 of the first hydraulic cylinder 31, and the first support 32 can be fixedly connected on the steel plate through welding or a bolt.

The driving device 4 comprises a motor 41, a speed reducer and a first roller 43, the motor 41 and the speed reducer are both fixedly arranged on the first support 32 through bolts, an input shaft of the speed reducer and an output shaft of the motor 41 are coaxially connected through a coupler, the first roller 43 is hinged on the first support 32 and is coaxially connected with the output shaft of the speed reducer through the coupler, and the axis of the first roller 43 is parallel to the cross beam 22. In order to control the rotation direction of the forging 8, the motor 41 is preferably a stepping motor 41.

In order to stabilize the rotation of the forging 8 during the rotation, a second bracket 33 and a second roller 34 are further provided on the sliding device 3, the second bracket 33 is arranged on the opposite side of the first bracket 32, and the second roller 34 is hinged with one end of the second bracket 33. And the first hydraulic cylinder 31 is set as a double-head hydraulic cylinder, and the second bracket 33 is connected with the second piston rod 312 of the double-head hydraulic cylinder in the same way as the first bracket 32, so that the second bracket 33 is connected with the workbench 1 in a sliding way along the direction vertical to the cross beam 22.

So two piston rods of first pneumatic cylinder 31 can contract simultaneously, and no matter be first running roller 43 or second running roller 34 earlier with forging 8 butt, all can make the piston rod of homonymy no longer move, until both ends butt simultaneously. So set up because the effect of forging 8 self gravity can make the axle center of forging 8 be located the crossbeam 22 under always, make the forging hammer all perpendicular to the axle center of forging 8 when forging and pressing forging 8 each time, promoted the machining precision of forging 8.

The first roller 43 and the second roller 34 are located on the same horizontal plane as the axis of the cross beam 22. If the first roller 43 and the second roller 34 are arranged too far upward, the forging hammer may fall onto the rollers to damage the rollers; if the first roller 43 and the second roller 34 are arranged too far downward, the forged part 8 is easily lifted during clamping, so that forging is inconvenient, and even forced forging can damage the driving device 4 and the sliding device 3.

Because forging 8 can form the one deck cinder after being forged and pressed, consequently first running roller 43's circumference face is the flank of tooth, can increase the frictional force between first running roller 43 and the forging 8, makes things convenient for forging 8 to rotate, can grind the cinder on the 8 circumference faces of forging simultaneously, and along with forging 8's rotation, the cinder can drop gradually. The second roller 34 may be toothed as the first roller 43 to increase the grinding effect.

Referring to fig. 2, in the prior art, an operator is required to use a clamp to assist in forging, so as to prevent the forged piece 8 from deviating. Therefore, in order to automatically prevent the displacement, the table 1 is provided with a first column 5 and a second column 6.

First pillar 5 and second pillar 6 set up the both sides at forging 8, and first pillar 5 and second pillar 6 all set up with workstation 1 is perpendicular. The first strut 5 is provided with a second hydraulic cylinder 7, the axis of the second hydraulic cylinder 7 is parallel to the axis of the cross beam 22, the second hydraulic cylinder 7 is welded with a shaft sleeve, a piston rod of the second hydraulic cylinder 7 is fixedly connected with the first strut 5 through the shaft sleeve and a bolt, a cylinder body of the second hydraulic cylinder 7 can be fixed on a strut of the saddle frame 2 through the shaft sleeve and the bolt, and the cylinder body can also be arranged in other places without relative movement with the strut. The arrangement is such that the first support 5 is slidably connected to the table 1 in the axial direction of the cross member 22.

The third roller 51 and the fourth roller 61 are both provided with a blind hole on the axis, and then are respectively sleeved on the first pillar 5 and the second pillar 6, so that the rollers can rotate relatively. When the piston rod of the second hydraulic cylinder 7 stretches out, the forge piece 8 can be automatically clamped, and the forge piece 8 is placed to be deviated. The axle centers of the first support 5 and the second support 6 and the axle centers of the two upright posts 21 of the saddle 2 are on the same plane, so that the third roller 51 and the fourth roller 61 can rotate relative to the forged piece 8 after clamping the forged piece 8, and the abrasion is not easy to occur. And along with the forging, the thickness of forging 8 constantly increases, and second pneumatic cylinder 7 is extruded indirectly to forging 8, forces the piston rod of second pneumatic cylinder 7 to withdraw, does not need manual adjustment.

In order to crush and remove the scale on both sides of the forged part 8, the third roller 51 and the fourth roller 61 are provided with the same circumferential surface as the first roller 43.

The implementation principle of the embodiment is as follows:

after the forging 8 is placed on the saddle 2, the first piston rod 311 and the second piston rod 312 are simultaneously contracted, so that the first roller 43 and the second roller 34 clamp the forging 8; meanwhile, the piston rod of the second hydraulic cylinder 7 extends out, so that the third roller 51 and the fourth roller 61 are pressed against the forged piece 8;

then, the forging hammer performs one-time hammering on the workpiece; then, the stepping motor 41 drives the forge piece 8 to rotate for a certain angle, and at the moment, the oxide skin on the circumferential surface of the forge piece 8 is crushed by the tooth surfaces of the first roller 43 and the second roller 34; simultaneously, the third roller 51 and the fourth roller 61 crush the oxide skin on the two end surfaces of the forge piece 8; circulating in sequence;

with the hammering of the forging hammer, the thickness and the outer diameter of the forging 8 are continuously increased, the outer surface of the forging 8 pushes the first piston rod 311 and the second piston rod 312 to extend out, and the first roller 43 and the second roller 34 automatically adapt to the size of the outer diameter of the forging 8; the two end surfaces of the forging 8 push the piston rod of the second hydraulic cylinder 7 to retract, so that the third roller 51 and the fourth roller 61 automatically adapt to the thickness of the forging 8.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
