Description

Technical Field

[0001] The invention relates to the field of production of plates for bimetallic bearings, and in particular to a powder spreading device for plates for bimetallic bearings. Background Art

[0002] Bimetallic materials are mainly used to make sliding bearings, bushings, etc., and are widely used in automobile engines, marine engines, steering systems, automobile chassis and hydraulic lifting equipment.

[0003] Its manufacturing process generally uses high-quality low-carbon steel back as the substrate, and spreads bronze alloy powder on the surface. After high-temperature sintering and rolling, a bimetallic material of copper and steel is formed. However, the existing production method basically adopts manual sprinkling of copper powder, and then scraping off excess powder with a scraper. The labor intensity is high and the production capacity is low, resulting in uneven powder spreading, and the dust is harmful to the workers. To solve this problem, the present invention proposes a plate powder spreading device for bimetallic bearings. Summary of the invention

[0004] In order to overcome the defects of the prior art, the present invention provides a plate powder spreading device for a bimetallic bearing.

[0005] The technical solution adopted by the present invention is: a plate powder spreading equipment for bimetallic bearings, including a workbench, on which a plate stacking area, a material transfer area, a powder spreading area and a conveyor belt are arranged in sequence, the conveyor belt is arranged between the plate stacking area, the material transfer area and the powder spreading area, and a plurality of plates are arranged on the plate stacking area; the material transfer area is provided with a vacuum suction cup for absorbing the plate, a motion module connected to the vacuum suction cup and a feed pressure roller, the feed pressure roller is located on the adjacent side of the powder spreading area, the powder spreading area is provided with a frame, a powder hopper, a primary scraper, a fine scraper and a mounting frame, the powder hopper is arranged on the frame, the mounting frame is movably connected to the frame, and a powder leakage channel is provided at the bottom of the powder hopper, the powder leakage channel is located between the mounting frame and the feed pressure roller; the mounting frame is provided with two sets of lifting mechanisms that respectively cooperate to drive the primary scraper and the fine scraper to rise and fall, and the two sets of lifting mechanisms are symmetrically arranged, and the two sets of lifting mechanisms are provided with a first connecting plate and a second connecting plate that respectively cooperate to connect the primary scraper and the fine scraper.

[0006] The advantage of adopting the above scheme is that the staff drives the vacuum suction cup to absorb the plate on the plate stacking area through the motion module according to the demand, and then runs it to the conveyor belt after absorption. The conveyor belt moves the plate in the direction of the feeding roller until it passes through the feeding roller and reaches the bottom of the powder hopper, and then opens the powder hopper. The copper powder on the powder hopper flows to the surface of the plate through the powder leakage channel, further realizing the powder spreading, and then continues to move in the direction of the mounting frame through the conveyor belt. Under the condition that the plate does not stop moving, the lifting structure on the mounting frame drives the initial scraper to perform preliminary scraping of the copper powder on the plate, and then drives the fine scraper through the lifting structure on the mounting frame to perform precise scraping of powder, so that the powder spreading is more uniform, further replacing manual powder spreading, and scraping off excess powder during the powder spreading process, greatly reducing the intensity of manual labor.

[0007] The present invention is further configured as follows: the lifting mechanism includes a driving motor, a screw and a screw nut, one end of the driving motor is arranged on the mounting frame, and the other end is connected to the screw, the screw nut is arranged on the screw, and the first connecting plate and the second connecting plate are respectively arranged on the corresponding screw nuts.

[0008] The advantage of adopting the above scheme is that due to the different thickness of the plates, the staff need to adjust the distance between the initial scraper and the fine scraper and the plates. The initial scraper and the fine scraper in this design are adjusted in the same way. Turn on the drive motor, and the drive motor drives the screw rod for transmission. The first connecting plate and the second connecting plate move up and down along the movement trajectory of the screw nut on the screw rod, thereby further realizing the up and down adjustment of the initial scraper and the fine scraper. The fine scraper is adjusted according to the thickness of the copper powder after the initial scraper has initially scraped the powder before scraping the powder. The adjustment method is simple, which is convenient for the staff to operate, and is convenient for the initial scraper and the fine scraper to perform initial scraping and precise scraping of powder.

[0009] The present invention is further configured as follows: a mounting seat is provided at the lower end of the mounting frame, a bearing seat is installed on the mounting seat; the driving motor has an output shaft, a rolling bearing is installed on the output shaft, and the output shaft is installed on the bearing seat through the rolling bearing.

[0010] The advantage of adopting the above scheme is that when the driving motor is working, the bearing seat rotates in conjunction with the rolling bearing on the output shaft, further improving the stability of the screw rotation, thereby making the initial scraper and the fine scraper smoother during adjustment.

[0011] The present invention is further configured as follows: a primary scraper frame and a fine scraper frame are respectively provided on the first connecting plate and the second connecting plate, the primary scraper is installed on the primary scraper frame, and the fine scraper is provided on the fine scraper frame.

[0012] The advantages of adopting the above scheme are: the installation method of the primary scraper and the fine scraper is the same, the primary scraper is set on the first connecting plate through the primary scraper frame, and since the primary scraper, the primary scraper frame and the first connecting plate are detachable structures, it is further convenient for the staff to promptly disassemble the primary scraper and the fine scraper for inspection and replacement.

[0013] The present invention is further configured as follows: a mounting plate is provided on the second connecting plate, and a row of tungsten steel contacts is provided at the lower end of the mounting plate.

[0014] The advantages of adopting the above scheme are: the bottom horizontal plane of the tungsten steel contact is lower than the bottom horizontal plane of the fine scraper. When the plate reaches under the tungsten steel contact of the mounting plate, the tungsten steel contact contacts the upper part of the plate. When the conveyor belt continues to run toward the fine scraper, if the plate is thick, the tungsten steel contact will lift the entire mounting frame upwards. If the plate is thin, the mounting frame moves downwards, further ensuring that the powder thickness is not affected by the thickness of the plate.

[0015] The present invention is further configured as follows: a powder outlet is provided at the lower end of the powder hopper, and the powder leakage channel is installed on the powder outlet of the powder hopper; a powder stop valve and a powder lower valve are provided in the powder leakage channel, and the powder lower valve is located below the powder stop valve.

[0016] The advantages of adopting the above scheme are: the powder stop valve can prevent the powder hopper from flowing too fast when discharging powder, and further effectively stop the copper powder. The powder discharging valve serves as a switch between the powder hopper and the powder leakage channel, and further controls the powder leakage channel to discharge powder. The copper powder in this design is adjusted manually, so as to avoid the powder hopper and the powder leakage from discharging too fast, resulting in uneven powder spreading.

[0017] The present invention is further configured as follows: a knife pillow is arranged on the workbench, and the knife pillow is located at the lower end of the mounting frame.

[0018] The advantages of adopting the above scheme are: the conveyor belt conveys the plate to the top of the knife pillow on the workbench, and the lifting mechanism on the mounting frame drives the preliminary scraper and the fine scraper to perform preliminary scraping and precise scraping of the copper powder on the plate in turn. During the preliminary scraping and precise scraping process, the knife pillow supports the plate, making it convenient for the preliminary scraper and the fine scraper to scrape the copper powder.
