Description

Technical Field

[0001] The utility model relates to the field of forging, in particular to a forging clamp for preventing it from falling off. Background Art

[0002] Free forging is one of the commonly used forging methods for high-temperature alloy forgings. Its advantage is that it can forge parts with complex shapes and has high precision and strength. During the free forging process, the high-temperature alloy billet needs to be heated to reach the forging temperature, and then the billet is forged through the forging equipment to form the required shape and size.

[0003] During forging, the forging needs to be moved, and the forging is always in a high temperature state. Therefore, it is extremely important to clamp and fix the forging with a fixture. The current fixture is directly clamped by a robot without any protective measures. When the clamping force of the robot is insufficient, the forging will slip, thus affecting the safety of the workers. Utility Model Content

[0004] The utility model aims to provide a clamp for clamping and stably preventing forgings from falling.

[0005] The purpose of the utility model is achieved as follows: A forging anti-drop clamp comprises a rotating base, a horizontal fixed seat, a hydraulic rod placed on the horizontal fixed seat, and a linkage clamping mechanism connected to the hydraulic rod;

[0006] The back of the rotating base is connected to the output end of the motor, and the horizontal fixed base is fixedly connected to the rotating base; the hydraulic rod is placed under the horizontal fixed base;

[0007] The linkage clamping mechanism consists of a fixed plate, a connecting rod and a clamping rod; the fixed plate is connected and fixed to the extended end of the hydraulic rod, connecting rods are hinged at both ends of the fixed plate, the other end of the connecting rod is connected to the clamping rod, the middle parts of the two sets of opposite clamping rods are hinged to the cross rod, and the cross rod is connected to the horizontal fixed seat upward through the support rod.

[0008] Preferably, an L-shaped plate is provided on the main body of the hydraulic rod and connected to the horizontal fixing seat, and reinforcing ribs are provided between the L-shaped plate, the horizontal fixing seat and the rotating base.

[0009] Preferably, a plurality of fixing holes are provided on the clamping rod located outside the cross bar, and the fixing holes are used to install the arc-shaped abutment members.

[0010] Preferably, the horizontal fixing seat is connected by a first fixing seat and a second fixing seat, the first fixing seat is placed above the hydraulic rod, and the second fixing seat is placed above the linkage clamping mechanism.

[0011] Preferably, the connecting rod and the protruding end of the hydraulic rod are arranged at an acute angle.

[0012] Preferably, a U-shaped docking groove is provided on the side of the second fixing seat facing the first fixing seat, and the U-shaped docking groove wraps the first fixing seat and is fixed by bolts.

[0013] Compared with the prior art, the utility model is beneficial in that:

[0014] 1. A removable arc-shaped abutment is provided on the inner side of the clamping rod. Since most forgings are cylindrical, the arc-shaped abutment can better fit the outer side of the forgings, and also avoid the influence of the high temperature of the forgings on the clamping rod. When the arc-shaped abutment is deformed, it only needs to be replaced separately, which greatly reduces the replacement frequency of the clamping rod;

[0015] 2. A second fixing seat is arranged above the clamping rod so that the second fixing seat can contact one end of the forging. When in use, the second fixing seat contacts one end of the forging, and then the hydraulic rod is started to clamp the forging; in conjunction with the rotating base, the linkage clamping mechanism is rotated ninety degrees as a whole, that is, the second fixing seat is rotated from the top to the bottom, to ensure that when the clamping rod is loosened, the forging can be stabilized on the second fixing seat, thereby avoiding the forging from falling due to unstable clamping force, further avoiding danger to workers, and improving safety.

[0022] The back of the rotating base 1 is connected to the output end of the motor, and the horizontal fixed base 2 is fixedly connected to the rotating base 1; the hydraulic rod 3 is placed under the horizontal fixed base;

[0023] The linkage clamping mechanism 4 is composed of a fixed plate 401, a connecting rod 402, and a clamping rod 403; the fixed plate 401 is connected and fixed to the protruding end of the hydraulic rod 3, and the connecting rods 402 are hinged at both ends of the fixed plate 401, and the other end of the connecting rod 402 is connected to the clamping rod 403. The middle parts of the two sets of opposite clamping rods 403 are hinged to the cross bar 5, and the cross bar 5 is connected to the horizontal fixed seat 2 upward through the support rod 6.

[0024] like Figure 1 As shown, L-shaped plates 7 connected to the fixing plate 401 are provided on both sides of the main body of the hydraulic rod 3, and reinforcing ribs 701 are provided on both sides of the L-shaped plate 7.

[0025] like Figure 1As shown, an L-shaped plate 7 is provided on the main body of the hydraulic rod 3 and connected to the horizontal fixing seat 2. Reinforcing ribs 8 are provided between the L-shaped plate, the horizontal fixing seat and the rotating base to increase the stability of the hydraulic rod and the horizontal fixing seat.

[0026] like Figure 1 As shown, a plurality of fixing holes are provided on the clamping rod 403 located outside the cross bar 5, and the fixing holes are used to install the arc-shaped abutment members 9. The arc-shaped abutment members can be replaced at any time without affecting the structure of the clamping rod, thereby reducing the use cost.

[0027] like Figure 1 As shown, the two horizontal fixing seats are connected by a first fixing seat 201 and a second fixing seat 202. The first fixing seat 204 is placed above the hydraulic rod, and the second fixing seat 202 is placed above the linkage clamping mechanism 4.
