Description

Technical Field

[0001] The utility model relates to the technical field of cleaning oxide layers on the surface of forged pieces, in particular to a device for cleaning metal forging oxide scales. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal materials. Since forgings need to undergo heat treatment before forging, the heated blanks will be in contact with the air and react chemically with the oxygen in the air to form an oxide layer on the surface of the steel, namely, scale. Once the scale is produced, it may be forged into the forging during the forging process, affecting the forging quality. Therefore, the scale on the surface of the forging needs to be cleaned before forging.

[0003] The existing device for cleaning the surface oxide scale of forgings is mainly composed of a double roller system, a drive system and a grinding cleaning wheel: the double roller system includes two parallel rollers for supporting and conveying the forgings to be cleaned. The rollers are made of wear-resistant materials and can resist high temperature and wear of oxide scale. The drive system is responsible for driving the rotation of the double rollers. In the process of cleaning the oxide scale of forgings, the forgings to be cleaned are first placed on the double rollers, and the motor drives the double rollers to rotate, thereby driving the forgings forward. When the forgings pass under the grinding cleaning wheel, the grinding motor drives the grinding cleaning wheel to rotate. The high-speed rotation of the grinding cleaning wheel can remove the oxide scale on the surface of the forgings.

[0004] Since the oxide scale on the surface of the forging is usually hard and rough, it will produce high-intensity friction when it comes into contact with the grinding and cleaning wheel, which may cause obvious wear of the grinding and cleaning wheel in a short time. The existing forging oxide scale cleaning device usually needs to stop the machine and disassemble the relevant parts of the equipment when replacing the worn grinding and cleaning wheel. The replacement steps are relatively complicated and time-consuming, which makes it inconvenient to quickly replace the grinding and cleaning wheel, thereby affecting the subsequent work efficiency. In addition, in the existing technology, it is not convenient to adjust the distance between the two double rollers, so that it cannot adapt to the cleaning needs of forgings of different sizes, thereby reducing the application range of the cleaning device. Therefore, a metal forging oxide scale cleaning device is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes a metal forging oxide scale cleaning device.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a metal forging oxide scale cleaning device described in the present invention includes a base; two pneumatic cylinders are installed on the base, and the working ends of the two pneumatic cylinders are equipped with pneumatic rods, and the top ends of the two pneumatic rods are fixedly connected to fixed plates. A shell is fixed between the two fixed plates, and a rotating shaft is rotatably installed in the shell, and a rotating cylinder is mounted on the rotating shaft. A first motor is installed on the side wall of the shell, and the output end of the first motor is connected to one end of the rotating shaft. Four mounting seats are fixed on the circumferential surface of the rotating cylinder, and a rotating rod is rotatably installed in each mounting seat, and each rotating rod is mounted with a grinding and cleaning wheel. A second motor is installed on one side wall of each mounting seat, and the output of the second motor The output end is connected to one end of the rotating rod. Since the oxide scale on the surface of the forging is usually hard and rough, high-intensity friction will be generated when it contacts the grinding and cleaning wheel, resulting in obvious wear of the grinding and cleaning wheel in a short time. In order to ensure the subsequent grinding effect, the grinding and cleaning wheel needs to be replaced. When replacing, the first motor is started to make the rotating shaft drive the rotating cylinder to rotate, thereby forcing the grinding and cleaning wheel to rotate as well. Until the new grinding and cleaning wheel to be replaced rotates to the bottom, the first motor stops working, and then the positioning rod is inserted into the positioning socket to fix the mounting seat at the top, thus completing the replacement of the grinding and cleaning wheel. This structural design is relatively simple and convenient to operate, facilitates the rapid replacement of the grinding and cleaning wheel, and greatly improves work efficiency.

[0007] Preferably, a positioning hole is provided on the other side wall of each mounting seat, and a positioning hole is also provided on one side wall of the shell, and a positioning rod is inserted into the positioning hole. When the rotating drum drives the grinding and cleaning wheel to the bottom, the first motor stops working, and then the positioning rod is inserted into the positioning hole to fix the mounting seat, thereby increasing the stability of the cleaning equipment.

[0008] Preferably, the base is provided with two limiting slides, each limiting slide is interspersed with two slides, and a conveying roller is installed between the two slides in different limiting slides through a rotating shaft, and a third motor is installed on one of the slides, and the output end of the third motor is connected to one end of the rotating shaft.

The output end of the motor is connected to the end of one of the bidirectional screw rods. When the distance between the two conveying rollers is adjusted as needed, the fourth motor is started to rotate the bidirectional screw rod. With the cooperation of the limiting slide groove, the two movable blocks drive the two slide plates closer to or away from each other, thereby making the distance between the two conveying rollers closer to or away from each other. Until the distance between the two conveying rollers meets the requirements, the fourth motor stops operating, so that the distance between the two conveying rollers can be adjusted as needed to meet the conveying and cleaning requirements of different forged steel columns, greatly improving the scope of use of the device.

[0009] Preferably, a vertical plate is fixed on the base, and an inclined guide hopper is fixed on the top of the vertical plate. When the device is used, the inclined guide hopper is provided to facilitate the cleaning of the forgings by sliding them out along the inclined guide hopper.

[0010] The utility model is beneficial in that:

[0011] 1. In order to ensure the subsequent grinding effect, the utility model needs to replace the worn grinding and cleaning wheel. When replacing, the first motor is started to make the rotating shaft drive the rotating drum to rotate, thereby forcing the grinding and cleaning wheel to rotate. When the new grinding and cleaning wheel to be replaced rotates to the bottom, the first motor stops working, and then the positioning rod is inserted into the positioning socket to fix the mounting seat at the top, thus completing the replacement of the grinding and cleaning wheel. This structural design is relatively simple and convenient to operate, and is convenient for rapid replacement of the grinding and cleaning wheel, greatly improving work efficiency.

When the distance between the two conveying rollers is adjusted as needed, the utility model starts the fourth motor to rotate the bidirectional screw rod, and with the cooperation of the limiting slide groove, the two movable blocks drive the two slide plates to move closer to or away from each other, thereby making the distance between the two conveying rollers move closer to or away from each other. After the distance between the two conveying rollers meets the requirement, the fourth motor stops operating, thereby being able to adjust the distance between the two conveying rollers as needed to meet the conveying and cleaning requirements of different forged steel columns, thereby greatly improving the scope of use of the device.

A first motor 6 is installed on the side wall of the shell 5, and the output end of the first motor 6 is connected to one end of the rotating shaft 7. Four mounting seats 9 are fixed on the circumferential surface of the rotating cylinder 8, and a rotating rod 10 is rotatably installed in each mounting seat 9. Each rotating rod 10 is mounted with a grinding and cleaning wheel 11, and a second motor 12 is installed on one side wall of each mounting seat 9, and the output end of the second motor 12 is connected to one end of the rotating rod 10; due to the forging The oxide scale on the surface is usually hard and rough, and high-intensity friction will be generated when it comes into contact with the grinding and cleaning wheel 11, which may cause obvious wear of the grinding and cleaning wheel 11 in a short time. In order to ensure the subsequent grinding effect, the grinding and cleaning wheel 11 needs to be replaced. When replacing, start the first motor 6 to make the rotating shaft 7 drive the rotating cylinder 8 to rotate, thereby forcing the grinding and cleaning wheel 11 to rotate as well. Until the new grinding and cleaning wheel 11 that needs to be replaced rotates to the bottom, the first motor 6 stops working, and then the positioning rod 14 is inserted into the positioning socket 13 to fix the mounting seat 9 at the top, thus completing the replacement of the grinding and cleaning wheel 11. This structural design is relatively simple and convenient to operate, and is convenient for rapid replacement of the grinding and cleaning wheel 11, greatly improving work efficiency.

[0022] A positioning hole 13 is provided on the other side wall of each mounting seat 9, and a positioning hole 13 is also provided on one side wall of the shell 5, and a positioning rod 14 is inserted into the positioning hole 13; when the rotating drum 8 drives the grinding and cleaning wheel 11 to rotate to the bottom, the first motor 6 stops working, and then the positioning rod 14 is inserted into the positioning hole 13 to fix the mounting seat 9, thereby increasing the stability of the cleaning equipment.

[0023] See also Figure 4-5As shown, the base 1 is provided with two limiting chutes 15, and each limiting chute 15 is interspersed with two slides 16. A conveying roller 17 is installed between the two slides 16 located in different limiting chutes 15 through a rotating shaft to cooperate with the rotation.

Under the cooperation of the limiting slide 15, the two movable blocks 22 drive the two slides 16 to move closer to or away from each other, thereby making the two conveying rollers 17 move closer to or away from each other. The distance between the two conveying rollers 17 also moves closer or farther away from each other, until the distance between the two conveying rollers 17 meets the requirement, and the fourth motor 21 stops working, so that the distance between the two conveying rollers 17 can be adjusted according to the needs, so that it can meet the conveying and cleaning requirements of different forged steel columns, which greatly improves the scope of use of the device; after the distance between the two conveying rollers 17 is adjusted, when cleaning the oxide scale on the surface of the forged workpiece, the forged workpiece to be cleaned is first placed on the two conveying rollers 17, and then the third motor 18 is started to convey the workpiece.

When the device is used, the inclined guide hopper 24 is provided to facilitate the cleaning of the forgings by sliding them along the inclined guide hopper 24 and removing them.

The existing forging oxide scale cleaning device usually needs to stop the machine and disassemble the relevant parts of the equipment when replacing the worn grinding and cleaning wheel 11. The replacement steps are relatively complicated and time-consuming, and it is inconvenient to quickly replace the grinding and cleaning wheel 11, which affects the subsequent work efficiency. In addition, in the prior art, it is not convenient to adjust the distance between the two double rollers, so it is impossible to adapt to the cleaning needs of forgings of different sizes, thereby reducing the application range of the cleaning device; therefore, the needle To solve the above problem, a metal forging scale cleaning device is proposed; in order to ensure the subsequent grinding effect, the grinding and cleaning wheel 11 needs to be replaced. When replacing, the first motor 6 is started to make the rotating shaft 7 drive the rotating cylinder 8 to rotate, thereby forcing the grinding and cleaning wheel 11 to rotate accordingly. When the new grinding and cleaning wheel 11 to be replaced rotates to the bottom, the first motor 6 stops working, and then the positioning rod 14 is inserted into the positioning socket 13 to fix the mounting seat 9 at the top, thus completing the replacement of the grinding and cleaning wheel 11.

[0026] Since the diameters of the forged steel columns are different, it is necessary to adjust the distance between the two conveying rollers 17 according to the diameters of the different forged steel columns, start the fourth motor 21, and rotate the bidirectional screw rod 20. With the cooperation of the limiting slide 15, the two movable blocks 22 drive the two slides 16 to move closer to or away from each other, thereby making the distance between the two conveying rollers 17 move closer to or away from each other, until the distance between the two conveying rollers 17 meets the requirements. The fourth motor 21 stops working, so that the distance between the two conveying rollers 17 can be adjusted as needed to meet the conveying and cleaning requirements of different forged steel columns, which greatly improves the scope of use of the device; the distance adjustment between the two conveying rollers 17 After completion, when cleaning the oxide scale on the surface of the forging, first place the forging to be cleaned on the two conveyor rollers 17, then start the third motor 18 to rotate the conveyor rollers 17, and then drive the forging forward. When the forging moves to the cleaning area, start the pneumatic cylinder 2, so that the pneumatic rod 3 drives the shell 5 to move vertically downward, and then the grinding and cleaning mechanism also moves downward until the grinding and cleaning wheel 11 moves down to conflict with the surface of the forging, and then start the second motor 12 to operate and rotate the grinding and cleaning wheel 11.
