[0002] In order to ensure the mechanical properties of the bearing seat, a forging press is required for forging. A forging press is a machine that uses hammering and other methods to make metal materials in a plastic state become workpieces with a certain shape and size and change its physical properties.
[0003] Using the end of a heavy forging hammer to hammer a workpiece at high speed will produce strong impact vibration. During forging, a large amount of oxide scale will fall off the workpiece, which needs to be cleaned in time. The existing method is to use a high-speed fan to blow continuously combined with manual cleaning, but the temperature of the workpiece drops relatively quickly, which is not conducive to forging. Summary of the invention
[0004] In order to overcome the technical defects of the prior art, the present invention provides a cleaning system for a press machine for processing a bearing seat, which can clean the oxide scale in time and has little effect on the temperature of the workpiece.

The cleaning system includes an airflow concentrator, a pressure generating device and an airflow injection device. A forming position is formed between the forging hammer device and the frame. The pressure generating device is slidably installed in the forging hammer device. A pressure chamber is formed between the pressure generating device and the forging hammer device. The airflow concentrator is installed at the bottom of the pressure chamber. The pressure generating device is transmission-connected to the airflow concentrator. The airflow concentrator has an air intake state and an air release state.

[0009] Preferably, the airflow concentrating device includes an airflow control ring and an airflow control return spring, the side of the airflow control ring is provided with an airflow control hole adapted to the airflow injection device, the airflow control ring slides along the side wall of the pressure chamber, the airflow control return spring is installed at the bottom of the pressure chamber, when the airflow control return spring is in a free state, the airflow control ring disconnects the airflow injection device from the pressure chamber, and when the pressure generating device presses down the airflow control ring, the airflow injection device is connected to the pressure chamber.
[0010] Preferably, the airflow concentrating device further comprises a limiting ring, and the limiting ring is located at the bottom of the airflow control ring.

[0014] The beneficial effects of the present invention are:
[0015] The forging hammer device is installed on the frame, and a forming position is formed between the forging hammer device and the frame. The forging hammer device is pressed down quickly until it hits the workpiece. The forging hammer device is blocked by the workpiece and stops instantly. The pressure generating device is slidably installed in the forging hammer device. A pressure chamber is formed between the pressure generating device and the forging hammer device. During the process of the forging hammer device stopping instantly, due to inertia and its own gravity, the pressure generating device continues to slide down along the pressure chamber, thereby making the air pressure in the pressure chamber higher and higher. The airflow concentrator is installed at the bottom of the pressure chamber, and the pressure generating device is connected to the airflow concentrator in a transmission manner. The airflow concentrator has an air intake state and an air release state. The pressure generating device drives the airflow concentrator to switch between the air intake state and the air release state.

The airflow injection device has a plurality of airflow ejection ports pointing to the forming position. The airflow injection device is connected to the airflow pushing device, thereby discharging the high-pressure gas in the pressure chamber to blow away the oxide scale. Since the airflow for blowing away the oxide scale is intermittent, it has little effect on the temperature of the workpiece, and can clean up the oxide scale in time as soon as the oxide scale falls after the forging impact.

[0030] The present invention will be further described below in conjunction with the accompanying drawings:
[0031] like Figure 1 — Figure 5As shown, this embodiment provides a cleaning system for a press machine for processing a bearing seat, which is installed on a forging hammer device 2 of the press machine, and the forging hammer device 2 is installed on a frame 1. The cleaning system includes an airflow concentrator 4, a pressure generating device 3 and an airflow injection device 5. The forging hammer device 2 is installed on the frame 1, and a forming position is formed between the forging hammer device 2 and the frame 1. The forging hammer device 2 is quickly pressed down until it hits the workpiece, and the forging hammer device 2 is blocked by the workpiece and stops instantly. The pressure generating device 3 is slidably installed in the forging hammer device 2, and a pressure chamber 6 is formed between the pressure generating device 3 and the forging hammer device 2. During the process of the forging hammer device 2 stopping instantly, due to the effects of inertia and its own gravity, the pressure generating device 3 continues to slide downward along the pressure chamber 6, thereby causing the pressure to The air pressure in the pressure chamber 6 is getting higher and higher. The airflow concentrator 4 is installed at the bottom of the pressure chamber 6. The pressure generating device 3 is connected to the airflow concentrator 4 in a transmission manner. The airflow concentrator 4 has an air intake state and a deflation state. The pressure generating device 3 pushes the airflow concentrator 4 to switch between the air intake state and the deflation state. When the air pressure in the pressure chamber 6 is the highest, the pressure generating device 3 pushes the airflow concentrator 4 to be in the deflation state. The airflow injection device 5 has a plurality of airflow nozzles pointing to the forming position. The airflow injection device 5 is connected to the airflow pushing device, and then the high-pressure gas in the pressure chamber 6 is discharged to blow away the oxide scale. Since the airflow for blowing away the oxide scale is intermittent, it has little effect on the temperature of the workpiece, and can clean up the oxide scale in time as soon as the oxide scale falls after the forging impact.
[0032] Specifically, the frame 1 includes two side walls 11, an upper support plate 12 and a lower pad 13. The sides of the two side walls 11 are provided with guide rails for the forging hammer device 2 to slide. The two side walls 11 are vertically and parallelly installed on the lower pad 13. The forming position is formed between the lower pad 13 and the forging hammer device 2. The upper support plate 12 is installed on the top of the two side walls 11. The stability of the frame 1 structure is ensured by setting the side walls 11.
[0033] Specifically, the forging hammer device 2 includes a forging cylinder 21, a forging guide slider 22 and a hammer head 23. The forging cylinder 21 is installed on the top of the frame 1, the forging guide slider 22 slides up and down along the guide rail of the frame 1, and the hammer head 23 is installed at the bottom of the forging guide slider 22. The pressure generating device 3 is slidably installed in the forging guide slider 22. The hammer head 23 stops instantly after hitting the workpiece. Under the combined action of inertia and gravity, the pressure generating device 3 continues to move downward and then generates high-pressure gas in the pressure chamber 6. In the process of the hammer head 23 accelerating downward under the push of the forging cylinder 21, the forging cylinder 21 pushes the hammer head 23 downward at an acceleration exceeding the acceleration of gravity. Due to the inertia of the pressure generating device 3, the volume of the pressure chamber 6 expands and is in an air intake state, thereby realizing air intake. The pressure chamber 6 is provided with a one-way valve 7 for one-way air intake to facilitate air intake.
[0034] In order to ensure that the pressure generating device 3 can move upward relative to the forging guide slider 22 when the hammer head 23 falls, a gas storage action device 8 is also provided on the top of the forging guide slider 22, and the gas storage action device 8 includes a gas storage push plate 83, a gas storage push rod 82 and a gas storage push airbag 81. The gas storage push plate 83 is installed on the top of the pressure generating device 3, the gas storage push rod 82 is rotatably installed on the top of the forging guide slider 22, and the gas storage push airbag 81 is installed on the top of the forging guide slider 22. Pressurized gas is stored in the gas storage push airbag 81, and the upper part of the gas storage push airbag 81 pushes the gas storage push rod 82 to rotate upward, and the top of the gas storage push rod 82 supports the gas storage push plate 83. In this way, when the hammer head 23 falls, the gas storage push rod 82 pushes the gas storage push plate 83 upward, ensuring that the pressure generating device 3 can move upward relative to the forging guide slider 22, so that the pressure chamber 6 can store gas through the one-way valve 7.
[0035] Specifically, the airflow concentrator 4 includes an airflow control ring 41 and an airflow control return spring 42. The side of the airflow control ring 41 is provided with an airflow control hole adapted to the airflow injection device 5. The airflow control ring 41 slides along the side wall of the pressure chamber 6. The airflow control return spring 42 is installed at the bottom of the pressure chamber 6. When the airflow control return spring 42 is in a free state, the airflow control ring 41 disconnects the airflow injection device 5 from the pressure chamber 6 (such as Figure 4 ), when the pressure generating device 3 presses down the airflow control ring 41, the airflow injection device 5 is connected to the pressure chamber 6 (such as Figure 5 ), the airflow control return spring 42 and the pressure generating device 3 jointly control the position of the airflow control ring 41, thereby realizing the disconnectable connection between the pressure chamber 6 and the airflow injection device 5.
[0036] Specifically, the airflow concentrator 4 further includes a limiting ring 43 , which is located at the bottom of the airflow control ring 41 . The limiting ring 43 is used to protect the airflow control return spring 42 to prevent the airflow control return spring 42 from being flattened.
[0037] Specifically, the pressure generating device 3 is a sliding column, each sliding column slides along the pressure chamber 6, and a sealing ring is provided between the sliding column and the pressure chamber 6, thereby achieving the sealing of the pressure chamber 6.
[0038] Specifically, the airflow injection device 5 is an injection pipe, one end of which is connected to the pressure chamber 6, and the other end of the injection pipe points to the forming position, thereby blowing the high-pressure air in the pressure chamber 6 toward the forming position to blow away the oxide scale.
