Description

Technical Field

[0001] The utility model belongs to the technical field of metal forging, and particularly relates to a forging device for a wide-width superalloy slab. Background Art

[0002] Superalloys are materials that can maintain stability and strength in high-temperature environments. These alloys are usually composed of base metals (such as nickel, chromium, tungsten, etc.) and additive elements (such as aluminum, molybdenum, etc.) to improve their high-temperature resistance, oxidation resistance, and corrosion resistance. They play an important role in aerospace, the energy field (such as gas turbines), chemical engineering, and other industrial applications that require high-temperature stability.

[0003] However, during the forging process of superalloy slabs, the phenomenon of non-uniform structure easily occurs, resulting in the alloy slabs not meeting the application requirements. The existing invention patent with the application number 202111267116 discloses a forging process for wide-width superalloy slabs, which controls the temperature during the forging of the slabs and performs multiple upsetting and drawing operations to ensure the uniform structure of the alloy slabs.

[0004] However, in the specific implementation process, after multiple upsetting and drawing operations, the slab needs to be widened. This widening step preferably has the length direction of the hammer head parallel to the length direction of the slab, so as to reduce the resistance. However, this hammer head is not conducive to upsetting and drawing, and the slab needs to be transferred. During the transfer process, the temperature of the slab drops, which easily leads to a decrease in the performance of the slab. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the hammer head of the current forging device for wide-width superalloy slabs is not conducive to slab widening described in the above background art. Here, a new forging device for wide-width superalloy slabs is proposed, which can realize the transformation of the hammer head and no longer requires slab transfer.

[0006] To achieve the above purpose, the technical solution adopted is a forging device for a wide-width superalloy slab, and the forging device includes:

[0007] A frame, which includes a base, a top plate, and a bracket, and the bracket connects the base and the top plate;

[0008] A forging unit, which includes a first hydraulic cylinder, a first hydraulic rod, a first forging hammer, a mounting plate, a second forging hammer, two second hydraulic cylinders, and two second hydraulic rods. The output end of the first hydraulic cylinder is connected to one end of the first hydraulic rod, the other end of the hydraulic rod is connected to the first forging hammer, the mounting plate is connected to the first hydraulic rod, the two second hydraulic cylinders are symmetrically arranged above the mounting plate, and the second hydraulic rod connects the second hydraulic cylinder and the second forging hammer;

[0009] A forging table, which is arranged above the base.

[0010] In the above technical solution, the first hydraulic cylinder can drive the first forging hammer to move up and down to hammer and forge the alloy slab, so as to broaden the alloy slab. The second hydraulic cylinder can drive the second forging hammer to move up and down, so that the first forging hammer and the second forging hammer are combined to perform upsetting and drawing out processes on the alloy slab.

[0011] Further, the forging device further includes a pressure equalizing unit. The pressure equalizing unit includes a first telescopic rod, a connecting member, a pressure equalizing plate and a rotating device. The connecting member connects the first telescopic rod and the pressure equalizing plate, and the rotating device is connected to the first telescopic rod.

[0012] Further, the pressure equalizing plate is square, and the bottom area of the pressure equalizing plate is greater than or equal to the sum of the bottom areas of the first forging hammer and the second forging hammer.

[0013] In the above technical solution, the first telescopic rod can drive the pressure equalizing plate to move up and down to fit the upper surface of the alloy slab, playing a role in pressure equalization and promoting the forming of the slab. The rotating device can make the pressure equalizing plate rotate away from the alloy slab.

[0014] Further, the forging device further includes an adjustment unit. The adjustment unit includes a support plate, a driving device, a connecting rod, a sliding block, a second telescopic rod and a manipulator. The support plate is fixedly connected to the side wall of the bracket. The driving device is arranged above the support plate. The connecting rod passes through the support plate to connect the driving device and the base. The sliding block is slidably connected to the connecting rod. The second telescopic rod connects the sliding block and the manipulator.

[0015] In the above technical solution, the adjustment unit is used to rotate and move the alloy slab and cooperate with the forging hammer to forge it.

[0016] Further, the first hydraulic cylinder is arranged above the top plate, and the first hydraulic rod passes through the top plate.

[0017] Further, the second forging hammer is cylindrical, and a groove is provided at the bottom of the second forging hammer.

[0018] Further, the width of the groove is equal to the width of the first forging hammer.

[0019] Further, the depth of the groove is equal to the height of the first forging hammer.

[0020] In the above technical solution, the first forging hammer can just be embedded in the groove of the second forging hammer, increasing the hammering area of the forging hammer to adapt to the upsetting and drawing out processes and making the forging of the alloy slab more uniformly stressed.

[0021] Further, the first forging hammer and the second forging hammer are located directly above the forging table.

[0022] The advantages of the present utility model are as follows:

[0023] 1. The present utility model drives the second forging hammer to move up and down through the second hydraulic cylinder, so that the first forging hammer and the second forging hammer are combined, making the device applicable to upsetting and drawing processes, and the first forging hammer can be used alone to broaden the alloy slab.

[0024] 2. The present utility model is provided with a pressure equalizing unit, which can control the movement of the pressure equalizing plate to make it fit the upper surface of the alloy slab, making the force on the alloy slab more evenly distributed and the forging effect better.
