[0002] A forging press is a machine that uses hammering and other methods to make metal materials in a plastic state into workpieces with a certain shape and size and change its physical properties. With the continuous progress of my country's equipment manufacturing and the continuous accumulation of technology, my country has made great progress in the field of precision equipment manufacturing. The ring shaft forgings of machine tools are key components in the equipment manufacturing industry. However, forging presses are indispensable for manufacturing shaft workpieces.

[0003] The fixed clamping devices of the existing forging presses are mostly manually operated to clamp the forgings and place them on the forging table for forging. It is necessary to clamp the forgings continuously to keep them in a fixed position, which is not convenient for long-term work. It is not only time-consuming and labor-intensive, but also harmful to human health when working under high temperature for a long time. At the same time, the forgings need to be turned over during the forging process, which is not convenient for manual operation.

[0004] For this purpose, we propose a fixed clamping device for a forging press. Utility Model Content

[0005] The main purpose of the utility model is to provide a fixing and clamping device for a forging press. By placing the forging on a forging table, the forging can be clamped and fixed by means of clamping plates arranged on both sides of the forging table. The forging can be lifted up by the setting of a top block, and the clamping plates can also be lifted up in conjunction with the lifting platform. The forging can be clamped in mid-air, which is convenient for flipping the forging. At the same time, the rotatable feature of the forging table itself makes it easy to adjust the flipping direction of the forging, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A second electric cylinder is fixedly installed inside the two bases, the output end of the second electric cylinder is fixedly connected to the bottom end of the second piston push rod, the top end of the second piston push rod is fixedly connected to the bottom end of the lifting platform, and the first electric cylinder is fixedly installed on the top end of the lifting platform.

[0009] Furthermore, the output end of the first electric cylinder is fixedly connected to one end of the first piston push rod, and the other end of the first piston push rod is rotatably connected to a rotating rod.

[0010] Furthermore, one end of the rotating rod away from the first piston push rod is fixedly connected to one side of the clamping plate, and the clamping plate, the rotating rod, the first piston push rod, the first electric cylinder and the lifting platform are all arranged at two locations relative to each other.

[0011] Furthermore, a third electric cylinder is fixedly mounted on the inner bottom of the mounting platform, and an output end of the third electric cylinder is fixedly connected to a bottom end of a third piston push rod.

[0012] Furthermore, the top end of the third piston push rod is fixedly connected to the bottom end of the top block, and a cavity is opened at the inner center of the forging table, and the cavity is used for installing and placing the top block and the third piston push rod.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a fixing clamping device of a forging press comprises a mounting table 10 and a base 8. A bearing 15 is fixedly installed inside the mounting table 10, and the bearing 15 is sleeved on the outer side of the forging table 1. The forging table 1 is rotatably mounted on the top of the mounting table 10. Bases 8 are fixedly provided on both sides of the mounting table 10. The forging table 1 can be fixed by setting a fixing mechanism such as a bolt to prevent the forging table 1 from rotating during the forging process.

[0020] A second electric cylinder 13 is fixedly installed inside the two bases 8, the output end of the second electric cylinder 13 is fixedly connected to the bottom end of the second piston push rod 11, the top end of the second piston push rod 11 is fixedly connected to the bottom end of the lifting platform 7, and the top end of the lifting platform 7 is fixedly installed with the first electric cylinder 6;

[0021] The output end of the first electric cylinder 6 is fixedly connected to one end of the first piston push rod 5, and the other end of the first piston push rod 5 is rotatably connected to the rotating rod 4; the end of the rotating rod 4 away from the first piston push rod 5 is fixedly connected to one side of the clamping plate 3, and the clamping plate 3, the rotating rod 4, the first piston push rod 5, the first electric cylinder 6 and the lifting platform 7 are all arranged at two locations opposite to each other;

[0022] A third electric cylinder 14 is fixedly installed on the inner bottom of the mounting table 10, and the output end of the third electric cylinder 14 is fixedly connected to the bottom end of the third piston push rod 12; the top end of the third piston push rod 12 is fixedly connected to the bottom end of the top block 2, and a cavity 9 is opened at the inner center of the forging table 1, and the cavity 9 is used for the installation and placement of the top block 2 and the third piston push rod 12.

[0023] It should be noted that the utility model is a fixing clamping device for a forging press. First, the forging is placed at the center of the forging table 1, and then two first electric cylinders 6 at opposite locations are started through an external power supply. The two first electric cylinders 6 drive the two first piston push rods 5 to approach each other, and then the two opposite clamping plates 3 are brought close to each other, so as to clamp and fix the forging placed on the forging table 1, which is convenient for subsequent forging work. When the forging needs to be turned over, the clamping of the clamping plate 3 on the forging is first released, and the forging table 1 is rotated through the bearing 15, so that the forging also rotates. After rotating to the appropriate direction, the third electric cylinder 14 is started through an external power supply, and the third electric cylinder 1 4 drives the third piston push rod 12 and the top block 2 to push upward, so that the forging can be lifted to a certain height, and then the second electric cylinder 13 is started by an external power supply, and the second electric cylinder 13 drives the second piston push rod 11 and the lifting platform 7 to push upward, thereby lifting the first electric cylinder 6 together with the clamp 3, and then the two clamps 3 are driven to approach each other by the two first electric cylinders 6 to clamp the suspended forging, and finally the top block 2 is retracted into the cavity 9 by starting the third electric cylinder 14. Since the clamp 3 is rotatably connected to the first piston push rod 5 through the rotating rod 4, at this time, the staff only needs to hold the forging with the clamp and rotate it, and finally put it down to the forging table 1.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
