[0001] The utility model relates to the technical field of oxide scale cleaning, in particular to an oxide scale cleaning device for the surface of forged alloy steel. Background Art

[0002] When the steel ingot is forged into round steel, there is oxide scale on the surface of the round steel, which needs to be cleaned while forging.

[0003] After searching, it was found that the Chinese utility model patent with authorization publication number CN221046716U discloses a scale cleaning device. It can be seen from its specification that by integrating the cleaning mechanism and the scraping mechanism together, when the cleaning mechanism needs to be used, the second extension tube is held in the hand to extend the cleaning mechanism to the round steel. When the scraping mechanism needs to be used, the first extension tube is held in the hand to extend the scraping mechanism to the round steel. There is no need to get close to scrape and clean the scale, which improves the convenience and safety of cleaning.

[0004] However, the oxide scale cleaning device in the above patent has the following problems: (1) the cleaning device needs to be held manually and the cleaning brush needs to be manually rotated to clean the oxide scale on the rod, and the cleaning brush cannot be controlled to automatically clean, resulting in low cleaning efficiency; (2) when cleaning the oxide scale, the cleaning device needs to be held manually, and the cleaning device is in a suspended state. After working for a long time, workers are prone to fatigue. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a device for cleaning oxide scale on the surface of forged alloy steel to solve the problems mentioned in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A device for cleaning oxide scale on the surface of forged alloy steel includes a cart with a motor installed on the cart, two bearing seats connected to the cart, a rotating shaft rotatably connected to the two bearing seats, the motor is transmission-connected to one end of the rotating shaft through a coupling, the other end of the rotating shaft is detachably connected to a cylinder, the telescopic end of the cylinder is connected to a disc, and a wire brush is connected to the disc.

[0008] Preferably, the cart includes two parallel cross bars, one end of each cross bar is connected to an inclined push rod, a top plate is connected between the two cross bars, the motor and the bearing seat are installed on the top plate, the bottom surfaces of the two cross bars are connected to V-shaped frames, an axle is connected between the two V-shaped frames, the two ends of the axle are rotatably connected to wheels, the bottom surfaces of the cross bars are connected to vertical bars, and the vertical bars are connected to the middle part of the V-shaped frames.

[0009] The above technical solution can improve the stability of the cart through the V-frame and vertical rods, and the wheels at the lower end of the V-frame can be used as a fulcrum to lift the end of the cart close to the wire brush upward to clean the oxide scale on the rods and reduce worker fatigue.

[0010] Preferably, two control buttons are provided on the cross bar near the push rod, which are used to control the operation of the motor and the cylinder respectively. A controller is installed on the bottom surface of the top plate, and the control buttons, motor and cylinder are all electrically connected to the controller.

[0011] The above technical solution can control the operation of the motor and the cylinder respectively through two control buttons.

[0012] Preferably, one end of the rotating shaft away from the motor is connected to a first flange, one end of the cylinder is connected to a second flange, and the cylinder is connected to the first flange of the rotating shaft through the second flange.

[0013] In the above technical solution, the cylinder and the rotating shaft are connected through the first flange and the second flange, which makes it easy to replace the cylinder and facilitate maintenance.

[0014] Preferably, the bottom surfaces of the two horizontal bars are also connected with a sleeve, and a support rod is slidably connected inside the sleeve. The length of the sleeve is less than the length of the vertical bar. The bottom surface of the support rod is connected with a support plate. A first positioning hole is provided on the support rod, and several second positioning holes are provided on the sleeve. The support rod is fixed to the sleeve by the cooperation of bolts, the first positioning hole and the second positioning hole.

[0015] When the cart is not in use, the bolts are removed, the support rod is slid downward to allow the support plate to contact the ground, and the bolts are then reinstalled to secure the support rod, thereby providing support for the cart. To clean the scale, the support rod is retracted into the sleeve, ensuring the support plate is sufficiently clear of the ground. The cart can then be rotated using the wheels as a fulcrum. Because the sleeve is shorter than the vertical rod, the sleeve and support rod do not hinder the cart's rotation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) When forging bars, push the cart to the side of the bar, then press down one end of the cart to make the wire brush face the bar, then control the cylinder to extend, drive the wire brush to contact the bar, and then start the motor to drive the shaft to rotate, thereby driving the cylinder and wire brush to rotate, so as to clean the oxide scale on the surface of the bar and improve the cleaning efficiency.

[0018] (2) When cleaning the oxide scale, the cart uses the wheels as a fulcrum, so workers do not need to keep their hands suspended in the air, reducing fatigue. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1 A device for cleaning oxide scale from the surface of forged alloy steel includes a cart 1, mounted with a motor 2, connected to two bearing blocks 3, rotatably connected to a shaft 4. The motor 2 is connected to one end of the shaft 4 via a coupling, and the other end of the shaft 4 is detachably connected to a cylinder 5. Specifically, the end of the shaft 4 away from the motor is connected to a first flange, and one end of the cylinder 5 is connected to a second flange. The cylinder 5 is connected to the first flange of the shaft 4 via the second flange, making cylinder replacement and maintenance easier. A disc 6 is connected to the telescopic end of the cylinder 5, to which a wire brush 7 is attached.

[0024] The cart 1 includes two parallel crossbars 101, each connected to an inclined push rod 102 at one end. A top plate is connected between the two crossbars 101, and the motor 2 and bearing seat 3 are both mounted on the top plate. The bottom surfaces of the two crossbars 101 are connected to V-shaped frames 103. A shaft 104 is connected between the two V-shaped frames 103. Wheels 105 are rotatably connected to the ends of the shaft 104. A vertical rod 106 is connected to the bottom surface of the crossbars 101, and the vertical rod 106 is connected to the middle of the V-shaped frames 103. The V-shaped frames 103 and vertical rod 106 can improve the stability of the cart 1. The wheel 105 at the lower end of the V-shaped frame 103 can be used as a fulcrum to lift the end of the cart 1 near the wire brush 7 upward to clean the oxide scale on the rods and reduce worker fatigue.

[0025] Two control buttons 107 are provided on the crossbar 101 near the push rod, which are used to control the operation of the motor 2 and the cylinder 5 respectively. A controller 108 is installed on the bottom surface of the top plate. The control buttons 107, the motor 2, and the cylinder 5 are all electrically connected to the controller 108. The controller 108 is provided with a control program, and the operation of the motor 2 and the cylinder 5 can be controlled respectively through the two control buttons 107.

[0026] The working principle of this embodiment is:

[0027] When forging bars, the trolley 1 is pushed to the side of the bar, and then one end of the trolley 1 is pressed down to lift one end of the wire brush of the trolley 1, so that the wire brush 7 is directed toward the bar. Then the cylinder 5 is controlled to extend to drive the wire brush 7 to contact the bar, and then the motor 2 is started to drive the rotating shaft 4 to rotate, thereby driving the cylinder and the wire brush 7 to rotate, so as to clean the oxide scale on the surface of the bar, thereby improving the cleaning efficiency.

[0028] Example 2

[0029] On the basis of Example 1, the bottom surfaces of the two horizontal bars 101 are also connected to a sleeve 109, and a support rod 110 is slidably connected inside the sleeve 109. The length of the sleeve 109 is less than the length of the vertical bar 106. The bottom surface of the support rod 110 is connected to a support plate 111. A first positioning hole is provided on the support rod 110, and a plurality of second positioning holes are provided on the sleeve 109. The support rod 110 is fixed to the sleeve 109 by the cooperation of bolts, the first positioning hole and the second positioning hole.

[0030] When not in use, remove the bolts, slide the support rod 110 downwards so that the support plate 111 contacts the ground, and then install the bolts to keep the support rod 110 fixed, thereby supporting the cart 1. When cleaning the oxide scale, retract the support rod 110 into the sleeve 109, so that the support plate 111 is at a sufficient distance from the ground, and then rotate the cart with the wheel 105 as the fulcrum. Since the length of the sleeve 109 is shorter than the length of the vertical rod 106, the sleeve 109 and the support rod 110 will not hinder the rotation of the cart 1.
