Advantageously, the included angle between the contact switches 211 is ninety degrees, initially, the left end face of the shifting block 29 abuts against the right end face of the upper side contact switch 211, and when the hammer head seat 20 moves downward, the shifting block 29 rotates to abut against the upper end face of the lower side contact switch 211.

The invention relates to a double-column forging machine, which comprises the following working procedures:

in an initial state, the shifting block 29 is abutted to the upper side contact switch 211, the electromagnet 53 is in a power-off state, the outer baffle spring 55 is in a compressed state, the lower end face of the threaded rotating wheel 63 is attached to the lower end wall of the threaded plate fixing cavity 52, the inner baffle spring 68 is in a relaxed state, the inner baffle 64 is completely positioned in the inner baffle cavity 62, the damping bead spring 26 is in a compressed state, and a part of the damping bead 24 is positioned in the damping bead limiting cavity 28.

If there is no workpiece on the forging platform 12, the hydraulic cylinder 31 is activated, so that the hydraulic cylinder 31 drives the hydraulic rod 32 to move downward, thereby driving the hammer head seat 20 to move downward, and further driving the hammer head 33 to move downward.

In the process of the downward movement of the hammer head seat 20, the gear 21 rotates under the action of the rack 13, so as to drive the limiting wheel 23 to rotate, further drive the limiting wheel shaft 27 to rotate, further drive the shifting block 29 to rotate, and further drive the shifting block 29 to be far away from the upper side contact switch 211.

When the shifting block 29 rotates to abut against the lower side contact switch 211, the electromagnet 53 is started, at this time, the shifting block 29 cannot rotate continuously due to the blocking of the lower side contact switch 211, the limit wheel shaft 27 stops rotating, the limit wheel 23 stops rotating, the hammer head seat 20 drives the gear 21 to rotate continuously, the damping ball 24 is pressed into the damping ball moving cavity 25, the damping ball spring 26 is compressed, and at this time, the limit wheel 23 and the gear 21 rotate relatively.

At this time, the limiting wheel 23 is started to enable the limiting wheel 23 to be electrically repelled from the outer baffle 60, so that the outer baffle 60 overcomes the pulling force of the outer baffle spring 55 to move upwards, and the threaded rotating wheel 63 is driven to move upwards.

Due to the long pitch between the threaded rotating wheel 63 and the threaded arc-shaped plate 51, when the threaded rotating wheel 63 moves upward relative to the threaded arc-shaped plate 51, the threaded rotating wheel 63 rotates to drive the screw shaft 66 to rotate, so that the lifting threaded block 67 moves upward, and under the elastic force of the inner baffle spring 68, the inner baffle 64 moves upward to be close to the lower end face of the hammer head seat 20 (as shown in fig. 8).

If the hammer head seat 20 drives the hammer head 33 to move downwards, the hammer head seat 20 pushes the inner baffle 64 to move downwards, so that the inner baffle spring 68 is compressed, and when the elastic force generated by the inner baffle spring 68 is greater than the elastic force of the outer baffle spring 55 and the resultant force of the repulsive force given by the electromagnet 53 to the outer baffle 60, the elastic force of the inner baffle spring 68 pushes the outer baffle 60 to move downwards, so that the threaded rotating wheel 63 rotates reversely, and the lifting threaded block 67 is driven to move downwards relative to the outer baffle 60.

At this moment, the inner baffle spring 68 generates an extension trend, then the inner baffle 64 moves downwards relative to the outer baffle 60 to the inner baffle cavity 62, the hammer head seat 20 pushes the outer baffle 60 to move downwards continuously, when the lower end face of the hammer head 33 abuts against the upper end face of the forging platform 12, the outer baffle 60 moves downwards to an initial position at this moment, and the inner baffle 64 is located at the initial position, so that the inner baffle 64 can always abut against the lower end face of the hammer head seat 20 in the process of forging the metal material downwards by the hammer head 33, namely, when the metal forging is performed, the baffle mechanism, the hammer head seat 20 and the forging platform 12 can surround the metal material, and the high-temperature oxide scale on the baffle mechanism can be prevented from splashing around.

In forging, a holding device located at the rear side of the main housing 10 holds the metal material to be forged and moves forward, and places the metal material on the forging stage 12.

The hydraulic cylinder 31 is started, so that the hammer 33 moves downwards to forge the metal material, and since the metal is clamped by the clamping device at the rear side of the forging platform 12, a solid operator does not stand at the rear side of the forging platform 12, so long as the high-temperature oxide skin on the metal material is prevented from splashing in the left, right, up and down direction and the front direction.

When one hammering is completed, the hammer head seat 20 drives the hammer head 33 to move upwards, then the gear 21 rotates reversely, so that when the damping bead limiting cavity 28 rotates again to align the damping bead moving cavity 25, the damping beads 24 are clamped into the damping bead limiting cavity 28 again under the elastic action of the damping bead spring 26, so that the gear 21 drives the limiting wheel 23 to rotate reversely, and further the shifting block 29 rotates reversely to abut against the upper side contact switch 211 to separate from the abutment from the lower side contact switch 211, so that the electromagnet 53 is closed.

At this time, the electromagnet 53 is turned off, so that the electromagnet 53 is de-energized, and the outer layer baffle 60 loses the repulsive force of the electromagnet 53, so that the outer layer baffle 60 moves downward to the initial position under the pulling force of the outer layer baffle spring 55.

In the process of outer baffle 60 downstream, screw thread runner 63 reverses for inner baffle 64 downstream to initial position, the device resumes initial state and waits for next hammering, thereby has realized forging the backplate mechanism at every turn and has withdrawed the state that makes things convenient for the operating personnel to observe metal material, improves and forges the effect.

The invention has the beneficial effects that: according to the invention, the baffle mechanism drives the inner baffle and the outer baffle to move upwards to the lower side of the hammer head, and the inner baffle spring and the outer baffle spring in the baffle mechanism drive the inner baffle and the outer baffle to move downwards together when the hammer head is forged, so that the forged metal material is surrounded by the three baffle mechanisms, the hammer head and the hammer head, high-temperature oxide skin splashing can be effectively prevented when the hammer head is forged, the operation safety of operators is greatly improved, meanwhile, the baffle mechanism is prevented from being damaged due to rigid impact of the hammer head, and the baffle mechanism is automatically retracted when the hammer head is retracted by hammering metal each time, so that the operators can conveniently observe the state of the metal material, and the forging effect is improved.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
