[0002] Forging is a common processing method, mainly using forging press to press metal blank to obtain a certain shape and size of the forging. In order to ensure the mechanical properties of the blank, the blank needs to be heated before forging. After heating the blank, the oxide skin is inevitably formed on the surface of the blank, so the blank needs to be descaled before forging.
[0003] Descale refers to removing the oxide skin on the surface of the blank to prevent defects from being pressed into the workpiece surface, thereby improving the surface quality of the product. Currently, the main way to remove the oxide skin is descaling machine and high-pressure water.
[0004] The descaling machine uses the two end faces of the blank as clamping surfaces to clamp the blank during descaling operation, and uses the polishing device to remove the oxide skin on the cylindrical surface of the blank. Since the end face of the blank is used for clamping, the oxide skin on the two end faces of the blank cannot be removed, and the oxide skin on the two end faces of the blank needs to be manually removed after the blank is removed, which is easy to be burned by the high temperature of the blank and has low work efficiency.
[0005] The high-pressure water descaling method can remove the oxide skin on the cylindrical surface and the two end faces of the blank. However, high-pressure water descaling can cause environmental pollution in the workshop and affect the internal structure of the blank, which is not suitable for descaling the uncooled blank.

[0023] In order to clearly illustrate the technical features of the scheme, the following through specific embodiment, the scheme is described.
[0024] In the forging process, the blank is usually cylindrical, and the descaling equipment of the embodiment removes the oxide skin on the two end faces of the cylindrical blank. After heating, the blank does not need to be cooled, and can be placed in the descaling equipment by the transfer machine for end face descaling. The end face of the blank is the plane where the two end heads of the blank are located.
[0025] Specifically, as Figure 1 shown, a double-end mechanical descaling equipment includes a base 4 and two descaling mechanisms 2 installed on the base 4 and oppositely arranged. A support frame 3 is arranged between the two descaling mechanisms 2 to support the blank 5. The two descaling mechanisms are located on the left and right sides of the blank and are symmetrically arranged about the blank.
[0026] The descaling mechanism 2 comprises a mounting base 11, a main shaft 9 rotationally connected with the mounting base 11, and a driving device 10 for driving the main shaft to rotate, wherein the driving device is an electric motor.

The descaling disc is further provided with a pair of radially extending scrapers 13 fixed on the side wall thereof facing the end surface of the blank, and the scrapers are arranged in the radial direction, and during rotation of the scrapers, the scrapers cover the entire end surface of the blank.
[0027] The rotation directions of the descaling discs of the two descaling mechanisms are opposite, so that relative movement occurs between the descaling discs and the blank, thereby removing the oxide scale.
[0028] The descaling mechanism further comprises a fixed disc 8 located at the side of the descaling disc 6 away from the blank, and the fixed disc 8 is fixedly connected with the main shaft 9, and the fixed disc, the main shaft, the descaling disc and the blank are coaxial, and a plurality of circumferentially distributed guide shafts 7 are fixedly arranged on the fixed disc and extend through the descaling disc 6 and are in sliding connection with the descaling disc, and springs 12 are further arranged on the guide shafts 7 and abut against the descaling disc 6 and the fixed disc 8 at two ends thereof. A through hole is formed in the descaling disc and is adapted to the guide shaft, and when the spring is in a natural state, the guide shaft extends into the through hole, and the guide shaft is used to transmit torque to drive the descaling disc to rotate, and the length of the through hole is used to provide space for movement of the descaling disc, thereby avoiding the guide shaft from abutting against the blank. The inner diameter of the through hole is greater than the diameter of the guide shaft, so that the descaling disc can be inclined relative to the guide shaft, and the spring is used to make the scrapers on the descaling disc better contact the end surface of the blank when the end surfaces of the blank are not parallel.
[0029] The end surface of the scraper 13 facing the blank is an inclined surface, and the distance between the inclined surface and the descaling disc gradually increases in the rotation direction of the descaling disc. The front edge of the inclined surface is a blade part, and during removal of the oxide scale, the rear part of the blade does not contact the oxide scale or the blank, thereby reducing the rotational resistance of the descaling disc.
[0030] The descaling disc is further provided with a toothed plate 14 fixed on the side wall thereof facing the end surface of the blank, and a plurality of teeth are fixed on the side wall of the toothed plate facing the end surface of the blank. The tips of the teeth face the end surface of the blank, and the axial height of the teeth is greater than the axial height of the blade part of the scraper, so that the teeth contact the oxide scale before the scraper, and the teeth are used to damage the oxide layer to facilitate removal of the oxide scale by the scraper.
[0031] The descaling device of the embodiment further comprises a driving mechanism for driving the at least one descaling mechanism to move towards the other descaling mechanism. As an optimization, the mounting seat 11 of the embodiment is in sliding connection with the base 4, and a sliding rail is fixed on the mounting seat, and a sliding groove adapted to the sliding rail is formed on the base, and the sliding rail and the sliding groove are arranged along the axial direction of the blank. The driving mechanism is a pushing cylinder 1 arranged along the axial direction of the blank, and the mounting seat of each descaling mechanism is connected with a pushing cylinder 1, and the pushing cylinder is used to drive the descaling mechanism to move close to or away from the blank.
[0032] The support frame 3 comprises at least two support tables distributed along the axial direction of the blank, and the support tables are detachably fixed to the base 4, and a placing groove adapted to the blank is formed on each support table. The placing groove of the embodiment is a V-shaped groove, and the corresponding support table can be replaced according to the diameter of the blank.
[0033] In use, the high-temperature cylindrical blank is placed horizontally on the support frame, and the two descaling mechanisms are pushed by the pushing cylinders on both sides, and the driving device is used to drive the descaling discs to rotate, and the rotation directions of the descaling discs of the two descaling mechanisms are opposite, the penetrating teeth on the descaling discs of the two descaling mechanisms first penetrate into the scale layer, and at the same time, the scale layer is damaged by the rotation, with the horizontal movement of the descaling mechanism, the scraper contacts the scale layer, and in the process of rotation, the scale on the two end faces of the blank is scraped off, after the scale is removed, the two pushing cylinders drive the two descaling mechanisms to move away from the blank, and the blank is moved away by using a reclaimer, and the next blank to be descaled is placed on the support frame, and the above process is repeated.
