Description

Technical Field

[0001] The invention relates to the technical field of forging processing, in particular to a forging oxide scale cleaning device. Background Art

[0002] Oxide scale refers to a thin layer of oxide formed on the surface of metal materials. This thin layer is usually generated by chemical reactions when the metal comes into contact with air or other oxidizing environments. The formation of oxide scale can protect the metal surface to some extent and prevent further oxidation or corrosion, but in some cases, the oxide scale may also affect the performance of the metal, especially in the electrical connection and welding process, which may cause poor contact.

[0003] Forgings are metal parts made by forging. Forging is the process of heating metal materials to a certain temperature and then forming them in a plastic state through mechanical pressure or impact. During the forging stage, oxide scale will be generated on the surface of the forging. With impact forging, most of the oxide scale flakes will fall off automatically, but there is still a part that adheres to the forging. After the forging cools naturally, it will be cut to remove the oxide layer. If the oxide scale agglomerates are not cleaned up in advance, it will affect the efficiency of the cutting operation and reduce the life of the cutting blade. A large-scale wind power flange forging oxide scale processing device (publication number: CN118253507B) published by the China Patent Office realizes the oxide scale cleaning of flange forgings. The oxide scale is cleaned by a scraper. The forgings in the device are placed vertically and rotated, which increases the difficulty of loading.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] Combined with Figure 1 , Attachment Figure 2 and attached Figure 5 As shown, a forging oxide scale cleaning device comprises a body 1 and a cleaning mechanism, a support foot 12 is provided at the bottom of the body 1, a main motor 2, a feeding frame 3, a displacement mechanism 4 and a pushing structure 5 are provided on the body 1, a baffle 11 is provided at an inclined position at the front end of the body 1, and the internal working parts of the body 1 are all inclinedly arranged, a driving wheel 21 is provided at the output end of the main motor 2 through a through hole on the baffle 11, a guard plate 14 is provided above the driving wheel 21 on the body 1, and the displacement mechanism 4 comprises a liftable driving frame 42 and two mounted on the driving frame 42. The driven wheel 43 and the feed rack 3 are used to guide the forging to slide toward the driven wheel 43 on the displacement mechanism 4. The pushing structure 5 pushes the forging to move to the cleaning position. The driving wheel 21 cooperates with the driven wheel 43 to rotate the forging. The cleaning mechanism includes an inner bottom surface cleaning mechanism 6 and an outer side surface cleaning mechanism 7. The inner bottom surface cleaning mechanism 6 cleans the oxide scale on the inner side surface and the rear bottom surface of the forging. The outer side surface cleaning mechanism 7 cleans the oxide scale on the front end surface and the outer side surface of the forging. A discharge trough 15 connected to the through hole on the baffle 11 is provided on the front side of the bottom of the machine body 1.

[0032] Combined with Figure 3 , Attachment Figure 4 , Attachment Fig. 9 and attached Fig.10 As shown, the inner bottom surface cleaning mechanism 6 includes two accompanying frames 61 installed on the pushing structure 5, and a cleaning roller 1 62 and a cleaning roller 2 63 are rotatably provided on the two accompanying frames 61 respectively. The cleaning roller 1 62 is arranged along the radial direction of the forging, and the cleaning roller 2 63 is arranged along the axial direction of the forging. One of the accompanying frames 61 is provided with a vertical plate 611, and an inclined plate 612 is arranged on the vertical plate 611. A wire brush 64 is arranged on the front side of the vertical plate 611 and the bottom of the inclined plate 612. The cleaning roller 1 62 and the cleaning roller 2 63 both include a roller body 621, and a plurality of limiting sliding cavities 622 are evenly arranged on the roller body 621. A rolling bar 623 is slidably provided in the limiting sliding cavity 622, and a spring piece 625 connected to the roller body 621 is provided on the rear side of the rolling bar 623. Limiting sliders 624 are provided on both sides of the rolling bar 623, and a groove that slidably cooperates with the limiting slider 624 is provided in the limiting sliding cavity 622.

[0033] Working principle of the inner bottom surface cleaning mechanism 6: the inner bottom surface cleaning mechanism 6 moves to the working position with the pushing structure 5, and the main motor 2 drives the forging to rotate. Since the roller body 621 contacts the rear bottom surface and the inner side surface of the forging, the rotation of the forging will drive the cleaning roller 1 62 and the cleaning roller 2 63 to rotate. When the roller body 621 rotates, the rolling bar 623 on the roller body 621 rotates accordingly. When the rolling bar 623 contacts the forging, the cutting edge at the front end of the rolling bar 623 will exert pressure on the oxide scale on the surface of the forging, so that the oxide scale breaks and falls off. As the rotation proceeds, the rolling bar 623 is retracted into the limiting sliding cavity 622. After the rolling bar 623 leaves the forging, the rolling bar 623 is reset by the spring 625, and the wire brush 64 will clean the residual oxide scale on the surface of the rotating forging. The wire brush 64 at the bottom of the obliquely arranged inclined plate 612 will sweep out the oxide scale at the through hole of the forging.

The output end of the hydraulic cylinder 3 71 is hinged to the shell 72. A driving mechanism is provided in the shell 72. The driving mechanism drives the cutter 73 to vibrate laterally. The driving mechanism includes a driving motor 74, a transmission part 75, a buffer part 76 and a mounting part 77. The driving motor 74 drives the transmission part 75 to vibrate laterally. The transmission part 75 transmits the force to the mounting part 77 through the buffer part 76. The cutter 73 is mounted on the mounting part 77.

[0035] Working principle of outer surface cleaning mechanism 7: after the forging reaches the cleaning position, hydraulic cylinder three 71 pushes housing 72 to rotate, so that the cutter 73 approaches and contacts the front end face and outer surface of the forging, and the curvature of the cutting edge of the cutter 73 fits with the front end face and outer surface of the forging. In the cleaning stage, the driving motor 74 drives the transmission part 75 to move, and transmits through the buffer part 76, so that the mounting part 77 vibrates along the radial direction of the forging, so that the cutting edge of the cutter 73 hits the forging with a high frequency, thereby achieving the purpose of cleaning.

[0037] Working principle of the driving mechanism: the driving motor 74 drives the gear 1 741 to rotate, and the gear 1 741 is meshed with the gear 2 752 to drive the rotating shaft 751 to rotate, so that the eccentric shaft 753 rotates around the axis of the rotating shaft 751, and the driving plate 755 is driven to move forward and backward through the transmission rod 754, and the driving plate 755 hits the front plate 761 of the buffer part 76. After the front plate 761 moves, the rear plate 762 moves through the spring 1 764, so that the rear plate 762 hits the collision plate of the mounting part 77 771, so that the mounting plate 772 drives the cutter 73 to move forward, so that the cutting edge of the cutter 73 hits the front end face and the outer side face of the forging, so as to clean the oxide scale.

At this time, the rear bottom surface of the forging contacts the baffle 11, and then the pushing structure 5 pushes the forging to a certain position, and then the hydraulic cylinder 141 pushes the driving rack 42 to move up, so that the outrigger 423 drives the driven wheel 43 to move up, until the two driven wheels 43 and the driving wheel 21 clamp the forging. At this time, the two driven wheels 43 and the driving wheel 21 pass through three Point support is used to fix the position of the forging. During this process, the driving slide column 422 cooperates with the driving slide groove 321 to rotate the guide frame 32. After the forging processing is completed, the hydraulic cylinder 41 drives the driving frame 42 to reset, and the guide frame 32 rotates and resets accordingly. Then the pushing structure 5 continues to push the forging forward, so that the forging is pushed from the driven wheel 43 to the angle frame 322. Then, the driving frame 42 moves up to rotate the guide frame 32, the angle frame 322 is lowered and the angle changes, and the forging slides from the angle frame 322 to the forklift arm.

[0041] Working principle of the pushing structure 5: hydraulic cylinder 2 51 pushes the push plate 53 forward through the transverse frame 52, so that the push plate 53 passes through the through hole on the baffle 11, and then multiple balls 54 contact the rear bottom surface of the forging, and the push plate 53 pushes the forging to the specified position. During the cleaning process, the forging rotates, and the friction between the push plate 53 and the forging is reduced by multiple rotatable balls 54.

[0042] During the specific implementation of the present invention, the annular forging is sent to the angle frame 322 by a forklift, and the forging slides onto the driven wheel 43, and then the forging is moved to the cleaning position through the cooperation of the displacement mechanism 4 and the pushing structure 5.
