Description

Blade forging correcting unit

Technical Field

The invention belongs to the blade forging processing technology, and particularly relates to a blade forging correcting device.

Background

The blade is a free-form surface part, can produce the deformation because of the cooling rate nonconformity of each position of forging in forging cooling process, and the cooling process is out of shape because of the factor production of dead weight and external pressure, also can produce the deformation of different degrees among the heat treatment process, accords with the type in order to improve the profile tolerance, adopts the mode of cold correction to carry out the plastic to the blade usually. The cold correction is that the blade exerts pressure on the blade at room temperature to generate plastic deformation, so that the blade reaches the contour degree in the target.

At present, the blades are characterized by small batch, multi-batch and the like. The hot-working production process of the blades in different levels has different degrees, the deformation with different trends needs to adjust the correction tool during correction, the replacement time is long, the efficiency is low, the correction difficulty is high, and the labor intensity of workers is high.

The invention aims to provide a blade forging correcting device, which aims to solve the problems of poor universality, high correcting difficulty and low efficiency in blade correction in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a blade forging correcting unit, its includes braced frame, blade hold assembly and correcting unit, wherein, blade hold assembly sets up in braced frame's bottom, treats the bottom mounting of rectifying the blade in blade hold assembly and whole vertical setting, be provided with lift drive arrangement in the braced frame, lift drive arrangement's drive end just is connected with the altitude mixture control board up, the fixed frame of drive has been placed on the terminal surface of altitude mixture control board, be provided with on the fixed frame of drive and rectify drive arrangement, it implements the plastic to rectify the blade to rectify driving arrangement connects correcting unit and treats.

In particular, the correcting component is a ring spanner for distortion reshaping, and a reshaping cavity matched with the section of the blade to be corrected is arranged at the center of the ring spanner.

Particularly, a circle of connecting holes for connecting the driving end of the correction driving device are formed in the periphery of the shaping cavity on one side face of the ring spanner.

In particular, the correcting component is a single-head compression column for bending deformation shaping.

In particular, the blade gripping member is a vise, which is provided in the support frame.

Particularly, two lifting driving devices are symmetrically and vertically arranged on two sides of the blade clamping component in the supporting frame, piston rods of the two lifting driving devices face upwards and are connected with a height adjusting plate.

In particular, the correction driving device and the lifting driving device both adopt hydraulic cylinders.

Compared with the prior art, the blade forging correcting device has the advantages that the structure is simple, and the operation is convenient; and the switching times of different blade correcting tools can be reduced, the clamping of the blades is convenient, the time is saved, the replacement of the blade correcting tools is reduced, and the utilization rate and the working efficiency of equipment are improved.

Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 to 4, in the present embodiment, a blade forging correcting device includes a square supporting frame 1, a vise 3 for clamping a blade 2 to be corrected is fixed at the bottom of the supporting frame 1, two hydraulic lifting cylinders 4 are symmetrically arranged at two sides of the vise 3 in the supporting frame 1, piston rods of the two hydraulic lifting cylinders 4 are arranged above and connected to a height adjusting plate 5, a square driving fixing frame 6 is placed on the end surface of the height adjusting plate 5, a shaping hydraulic cylinder 7 is arranged at opposite corners of the driving fixing frame 6, and the end portions of the two shaping hydraulic cylinders 7 are connected to a ring spanner 8 for distortion shaping.

The center of the ring spanner 8 is provided with a shaping cavity 9 matched with the section of the blade 2 to be corrected, and a circle of connecting hole 10 used for connecting the driving end of the shaping hydraulic cylinder 7 is formed in the periphery of the shaping cavity 9 on one side face of the ring spanner 8.

When the needs carry out the plastic to the bending deformation of blade, only need with annular spanner 8 change into the single-end compression leg can, come to carry out the plastic to the flexion of blade through shaping pneumatic cylinder 7 drive single-end compression leg.

The specific blade correction operation comprises the following steps:

1) the bottom end of the blade 2 to be corrected is fixed on the bench vice 3 and is vertically arranged as a whole;

2) the height of the ring spanner 8 is adjusted through the height adjusting plate 5, so that the ring spanner 8 can be sleeved on the position of the blade 2 to be corrected, which needs to be corrected;

3) the output torque of the shaping hydraulic cylinder 7 is used for driving the ring spanner 8 to rotate and enabling the blades to generate plastic deformation;

4) the deformation of the blade is controlled by controlling the stroke of the shaping hydraulic cylinder 7;

5) the vise is released to remove the blade for inspection.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
