Description

Technical Field

[0001] The invention relates to the technical field of roller parts processing, in particular to an automatic roller surface processing device. Background Art

[0002] Cold rolling rollers are complex components with very hard surfaces and are subject to great stress. Therefore, cold rolling rollers require high manufacturing quality, which is a necessary condition to ensure the use effect. The service life of cold rolling rollers not only depends on the manufacturing quality, but is also closely related to the maintenance during use. If used improperly, the use effect will change greatly. Fatigue spalling is the most common failure form in the use of rolling rollers. It originates from fatigue cracks on the surface of the rolling rollers. If such cracks cannot be completely removed before being put on the machine, they will fatigue and expand in the hardened layer to form a typical fatigue zone, and then fatigue spalling will occur. Prevention of such accidents should be carried out throughout the entire process of rolling roller operation.

[0003] Traditional roller spraying equipment has uneven coating due to uneven airflow or improper operation, and there are cases of missed spraying or uneven density. There is material waste in the spraying process, such as overspraying, material drifting and splashing during spraying, etc. Manual operation is often required to complete the cleaning, positioning and spraying of parts, which is not only inefficient, but also leads to uneven coating due to improper operation. The cleaning and pretreatment of the part surface are often not thorough enough, which affects the adhesion and quality of the coating. Manual operation is usually required, and there are problems such as inconsistent operating skills and high labor intensity. Due to incomplete cleaning or poor environmental conditions, the adhesion of the coating is affected, resulting in unsatisfactory coating quality.

[0049] Please refer to the attached Figure 1 -Attached Figure 8The centering and gathering mechanism 5 is located between the positioning drive mechanism 3 and the extension frame 2, and is used for the motion output of the spraying and smearing mechanism 8. The centering and gathering mechanism 5 includes two sets of side push components and a fixed platform 53, a rotating shaft column 55 and a center linkage plate 56. The side push components are distributed on both sides of the top of the base 1. The side push components are linked and transmitted through the fixed platform 53, the rotating shaft column 55 and the center linkage plate 56. The fixed platform 53 is fixedly connected to the center of the top of the base 1, the rotating shaft column 55 is rotatably connected to the top of the fixed platform 53, and the center linkage plate 56 is fixedly connected to the output shaft at the top of the rotating shaft column 55. The side push components include a hydraulic pusher 51, a transverse guide rail 52, a centering pusher 54, a double-end rotating rod 57, a linkage slide 58 and a zigzag fixed frame 59. The hydraulic pusher The movable member 51 is fixedly connected to the top of the base 1, the transverse guide rail 52 is fixedly connected to the top of the base 1 and is located between the hydraulic push members 51, the double-end rotating rod 57 is rotatably connected to the two ends of the central linkage plate 56, the linkage slide 58 is slidably connected to the transverse guide rail 52, the zigzag fixed frame 59 is fixedly connected to the top of the linkage slide 58, and the other side ends of the double-end rotating rod 57 are respectively rotatably connected to the top of the linkage slide 58, the upper part of the inner wall of the zigzag fixed frame 59 is fixedly connected to the push rod 510, the centering push platform 54 is fixedly connected to the inner end of the push rod 510 and is located above the positioning drive mechanism 3, and when the pneumatic cleaning mechanism 7 is started, the centering gathering mechanism 5 is synchronously opened, and the centering gathering mechanism 5 itself includes two sets of side push assemblies arranged opposite to each other on the top of the base 1 At the same time, the fixed platform 53, the rotating shaft column 55 and the central linkage plate 56 included in the centering and gathering mechanism 5 can make the two sets of side push assemblies run synchronously, and the hydraulic pushers 51 included in each of the side push assemblies are started. When the hydraulic pushers 51 are started and push a set of zigzag fixed frames 59 fixed at the conveying ends of the two sides to move to the right, the zigzag fixed frames 59 use the linkage slides 58 installed at the bottom to slide to the right on the two sets of transverse guide rails 52 installed on the top right side of the base 1. When the zigzag fixed frames 59 move to the right, the zigzag fixed frames 59 drive the corresponding double-end rotating rods 57 installed in the middle to rotate outward and unfold. After the movement of the double-end rotating rods 57, the fixed platform 53 installed at the other end is driven to start rotating along the rotating The moving shaft column 55 rotates, and the rotation of the center linkage plate 56 drives the other end of the other end to rotate and the other group of double-end rotating rods 57 installed on it rotates. The double-end rotating rods 57 rotate and expand outward at the same time. The double-end rotating rods 57 drive another group of zigzag fixed frames 59 to move outward along the linkage slide 58 installed at the bottom on the transverse guide rail 52 on the top side of the base 1, so that the two groups of zigzag fixed frames 59 can move in relative directions at the same time. The centering push platform 54 installed on the top of the two groups of zigzag fixed frames 59 through the push rod 510 clamps the rollers transported on the positioning drive mechanism 3 from the left and right sides, and corrects the position of the rollers from both sides. The side push assemblies are each equipped with a group of spraying and smearing mechanisms 8 set opposite to each other through the centering push platform 54.The material spraying and smearing mechanism 8 is simultaneously located on the surface of the positioning drive mechanism 3 in the direction of the roller conveying, when the centering pusher 54 is synchronously approached.

[0050] Please see attached Figure 1 -Attached Fig.11 The pneumatic cleaning mechanism 7 cooperates with the positioning driving mechanism 3 to blow and wash the rollers. At the same time, the material storage pool 81, the air inlet cylinder 76 and the driving turbofan 78 are used to drive the spraying and smoothing mechanism 8 to operate. The pneumatic cleaning mechanism 7 includes a main air pipe 71 and a pressurized air pipe 73. The main air pipe 71 is fixedly connected to the bottom wall of the fixed stand 4. The side wall of the main air pipe 71 is provided with evenly distributed output ports. The input port of the main air pipe 71 is fixedly connected to an air pump 72. The air pump 72 is fixedly connected to the side wall of the fixed stand 4. The pressurized air pipe 73 is fixedly connected to the bottom wall of the fixed stand 4. The air ducts 73 are evenly distributed and fixedly connected to the bottom wall of the fixed stand 4. The output port of the main air duct 71 is connected to the input port of the pressurized air duct 73. The end of the main air duct 71 away from the air pump 72 is fixedly connected to a three-way pipe 74. The three-way pipe 74 has two output ports and is fixedly connected to a gas hose 75. The output end of the gas hose 75 away from the three-way pipe 74 is fixedly connected to an air inlet cylinder 76. The air inlet cylinder 76 is fixedly connected to the side wall of the storage tank 81. The top wall of the air inlet cylinder 76 is fixedly connected to an exhaust pipe 77. The inner wall of the air cylinder 76 is rotatably connected to a driving turbofan 78, which is fixedly connected to the outer rotating shaft of the wiping roller 82. The shaft part first enters the interior of the fixed stand 4, and at the same time, the centering and focusing mechanism 5 and the pneumatic cleaning mechanism 7 are turned on. The air pump 72 included in the pneumatic cleaning mechanism 7 generates high-pressure wind and delivers it to the main air pipe 71, which is distributed and delivered to the pressurized air pipe 73 arranged side by side inside the fixed stand 4, and the pressurized air pipe 73 blows the high-pressure wind to the positioning drive mechanism The rollers transported by the air pump 72 are cleaned of dust before spraying. The high-pressure wind generated by the air pump 72 is continuously transported to the three-way pipe 74 along the main air pipe 71 and is transmitted to the air hose 75 by the three-way pipe 74. The two sets of air hoses 75 are transmitted to the corresponding air inlet cylinders 76. Since the high-pressure wind is directly blown into the air inlet cylinder 76, the driving turbofan 78 installed inside the air inlet cylinder 76 starts to rotate synchronously under the impact of the high-pressure wind. After passing through the driving turbofan 78, the high-pressure wind is discharged from the exhaust pipe 77 arranged on the top wall of the air inlet cylinder 76.

[0051] Please see attached Figure 1 -Attached Fig.11The spraying and smearing mechanism 8 is used for gathering and wiping the rollers through the cooperation of the wiping roller 82 and the centering push platform 54. The spraying and smearing mechanism 8 includes a storage pool 81, which is fixedly connected to the top wall of the centering push platform 54 and is adjacent to the fixed stand 4. The bottom wall of the storage pool 81 is provided with evenly distributed nozzles. The bottom wall of the storage pool 81 is rotatably connected to the wiping roller 82. The outer side of the bottom wall of the storage pool 81 is fixedly connected to a gathering ramp 83, and the gathering ramp 83 is rotatably connected to evenly distributed gathering wheels 84. The rotating shaft of the wiping roller 82 passes through the side wall of the storage pool 81. The storage pools 81 included in the spraying and smearing mechanism 8 are also close to each other. The gathering ramp 83 arranged at the bottom also synchronously moves closer to each other along the surface of the guide roller frame 31 and shovels the rollers against each other. The nozzle arranged on the bottom wall of the storage pool 81 starts to spray anti-rust paint on the surface of the roller. Because the driving turbofan 78 driven by the high-pressure wind also links the wiping roller 82 arranged inside the storage pool 81 to start rotating, a part of the wiping roller 82 is located inside the storage pool 81, and the anti-rust paint temporarily stored in the storage pool 81 can be wiped to the surface of the roller. While in contact and rotating, it will also drive the roller to start rotating along the gathering wheel 84 installed on the gathering ramp 83, and then spray the entire side, and also wipe and evenly spread the anti-rust paint on the surface of the parts.

[0052] Please see attached Figure 1 -Attached Fig.12 In view of the above embodiment, a roller surface automatic treatment device and treatment method are proposed, including:

[0053] S1. Roller conveying and positioning:

[0054] The rollers waiting to be coated with anti-rust paint are first transported through the positioning drive mechanism 3 fixed by the extension frame 2 on the top of the base 1. The guide roller frame 31 included in the positioning drive mechanism 3 is transported through its own distributed guide rollers, and the distributed guide rollers are linked to rotate by the butted belt transmission parts 32, and the output motor 33 is used to output the rotation torque to make the entire guide roller mechanism of the guide roller frame 31 operate and transport the rollers. The rollers first enter the interior of the fixed stand 4, and the centering and gathering mechanism 5 and the pneumatic cleaning mechanism 7 are turned on at the same time;

[0055] S2. Pneumatic cleaning and centering:

The high-pressure wind generated by the air pump 72 is continuously delivered to the three-way pipe 74 along the main air pipe 71 and is divided and transmitted to the air delivery hose 75 by the three-way pipe 74, and is conducted to the corresponding air inlet cylinder 76 by the two sets of air delivery hoses 75. Since the high-pressure wind is directly blown into the air inlet cylinder 76, the drive installed inside the air inlet cylinder 76 The turbofan 78 starts to rotate synchronously when being hit by the high-pressure wind. The high-pressure wind passes through the driving turbofan 78 and is discharged from the exhaust pipe 77 arranged on the top wall of the air inlet cylinder 76. When the pneumatic cleaning mechanism 7 is started, the centering and gathering mechanism 5 is opened synchronously. The centering and gathering mechanism 5 itself includes two sets of side thrust assemblies arranged opposite to each other on the top of the base 1. At the same time, the fixed platform 53, the rotating shaft column 55 and the center linkage plate 56 included in the centering and gathering mechanism 5 can make the two sets of side thrust assemblies run synchronously, and the hydraulic pushers 51 included in each of the side thrust assemblies are started. When the hydraulic pushers 51 are started and push a set of zigzag fixed frames 59 fixed at the conveying ends of the two to move to the right, the hydraulic pushers 51 are turned on and pushed. The zigzag fixing frame 59 is moved to slide to the right on the two sets of transverse guide rails 52 installed on the top right side of the base 1 by means of the linkage slide 58 installed at the bottom thereof. When the zigzag fixing frame 59 moves to the right, the zigzag fixing frame 59 drives the corresponding double-end rotating rod 57 installed in the middle thereof to rotate and unfold outward. After the movement of the double-end rotating rod 57, the fixed platform 53 installed in rotation at the other end thereof starts to rotate along the rotating shaft column 55. The rotation of the center linkage plate 56 drives the other set of double-end rotating rods 57 installed in rotation at the other end thereof to rotate. The rotation of the double-end rotating rods 57 is simultaneously unfolded outward. The double-ended rotating rod 57 drives another group of zigzag fixed frames 59 to move outwards on the transverse guide rail 52 on one side of the top of the base 1 along the linkage slide 58 installed at the bottom, so that the two groups of zigzag fixed frames 59 can move in relative directions at the same time. The centering push platform 54 installed on the top of the two groups of zigzag fixed frames 59 through the push rod 510 can clamp the rollers conveyed on the positioning drive mechanism 3 from both sides, and correct the position of the rollers from both sides. The side push assemblies are each installed with a group of spraying and smearing mechanisms 8 arranged opposite to each other through the centering push platform 54. The spraying and smearing mechanisms 8 are also located on the surface of the positioning drive mechanism 3 in the direction of roller conveying.

[0057] S3. Anti-rust paint spraying and spreading:

[0058] When the centering push platform 54 is synchronously approaching, the storage pools 81 included in the spraying and smoothing mechanism 8 are also approaching each other, and the gathering ramp 83 arranged at the bottom of the storage pool 81 is also synchronously approaching along the surface of the guide roller frame 31 and shoveling the rollers mutually, and the nozzles arranged on the bottom wall of the storage pool 81 begin to spray anti-rust paint on the surface of the roller, and because the driving turbofan 78 driven by the high-pressure wind also links the wiping roller 82 arranged inside the storage pool 81 to start rotating, a part of the wiping roller 82 is located inside the storage pool 81, and the anti-rust paint temporarily stored in the storage pool 81 can be wiped to the surface of the roller, and the contact rotation will also drive the roller to start rotating along the gathering wheel 84 installed on the gathering ramp 83, and then the entire side is sprayed, and the anti-rust paint on the surface of the parts can also be wiped and smoothed, and the anti-rust paint leaked through the guide roller frame 31 falls onto the recovery ramp 6;

[0059] S4: Positioning after recovery and coating:

[0060] The recovery ramp 6 is used to guide the return flow to the recovery pool 9 for recovery. The overall structure uses the high-pressure cleaning wind generated by the pneumatic cleaning mechanism 7 to drive the driving turbofan 78 to rotate, so that the driving turbofan 78 drives the wiping roller 82 in contact with the surface of the part to rotate, and the anti-rust paint and anti-rust liquid can be fully covered. The coated roller is continuously transported by the guide roller frame 31, and gradually passes through the gantry notch of the suspension frame 36 included in the positioning drive mechanism 3, and the roller is fixed again by the centering and gathering mechanism 5 and the spraying and smearing mechanism 8, and the suspension frame 36 It is a set of gantry suspension frame 36 structure, both ends of which are restricted in the side frames 34 installed on both sides of the top of the guide roller frame 31 by the added nut sub-structure, and the displacement of the suspension frame 36 is controlled by the fixed screw 35 installed in the side frame 34, so that the suspension frame 36 can carry the hydraulic output component 37 installed thereon and the extension seat 38 and positioning probe 39 installed at the output end of the hydraulic output component 37 to move above the roller until it reaches the coating position, and at the same time, the hydraulic output component 37 is turned on to make the extension seat 38 descend, so as to quickly position the roller.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
