Description

Technical Field

[0001] The invention relates to the technical field of forging hammers, in particular to a pneumatic forging hammer with automatic lubrication function and a use method thereof. Background Art

[0002] A forging hammer is a device that repeatedly hammers the forged piece into a specific shape. The pneumatic forging hammer drives the hammer head to move through the cylinder. The hammer head is generally subjected to a large impact when hammering the product, and the movement of the hammer head needs to be guided to avoid shaking when the hammer head is impacted, which affects the hammer forging of the product. The relative sliding of the guide parts will generate heat, so the relative sliding surfaces of the guide parts need to be lubricated.

[0003] The defects of the existing forging hammer are: 1. Prior art US4796428A discloses a double-acting forging hammer and method, which does not have the function of automatically lubricating the guide structure of the hammer head. When the lubricating oil is manually injected for lubrication, the lubricating oil is easy to evaporate, and the staff needs to pay attention to the amount of lubricating oil and add lubricating oil at any time. The operation process is complicated. When the lubricating oil is not replenished in time, the relative sliding of the hammer head and the guide structure is easy to cause friction damage, which affects the service life of the hammer head. Therefore, a pneumatic forging hammer with automatic lubrication function that can automatically add lubricating oil when the lubricating oil content becomes less is needed to solve this problem.

[0004] 2. The prior art EP3290718A1 discloses a hydraulic rapid forging device, which does not have a structure for recovering and filtering the lubricating oil in the guide structure. Impurities are easily introduced into the lubricating oil in the guide structure, causing the lubrication effect to deteriorate. Therefore, a pneumatic forging hammer with automatic lubrication function that can recover and filter the lubricating oil in the guide structure to ensure the lubrication quality is needed to solve this problem.

[0005] 3. The prior art US5715724A discloses an adaptive, self-adjusting forging hammer control system. This technology does not have the function of preventing dust from entering the guide structure. Since the guide structure slides repeatedly, dust entering the inside will cause damage to the sliding surface and affect the lubricating effect of the lubricating oil. Therefore, a pneumatic forging hammer with automatic lubrication function that can prevent dust from entering the guide structure is needed to solve this problem.

[0006] 4. The prior art CN105964854B discloses a forging hammer assembly of a forging die device. This technology does not have the function of regulating the temperature of the lubricating oil in the guide structure. When the temperature of the lubricating oil increases, the volatilization rate will also increase, resulting in an increase in the frequency of adding lubricating oil to the equipment and an increase in the labor intensity of the staff. Therefore, a pneumatic forging hammer with an automatic lubrication function that can cool the lubricating oil in the guide structure is needed to solve this problem. Summary of the invention

6. The pneumatic forging hammer with automatic lubrication function according to claim 1, characterized in that: A water box (24) is symmetrically mounted on the top of the plate body (1), a pump (25) is mounted on the top of the water box (24), and the pump (25) is electrically connected to the control unit (4); a drainage pipe (26) is mounted on the input end of the pump (25), and one end of the drainage pipe (26) passes through the inner wall of the top of the water box (24); a solenoid valve unit (27) is mounted on the output end of the pump (25), and the solenoid valve unit (27) is electrically connected to the control unit (4).

7. The pneumatic forging hammer with automatic lubrication function according to claim 6, characterized in that: A water box 2 (29) is installed on one side of the guide frame (9); a water inlet pipe (28) is installed at the bottom input end of the water box 2 (29), and the input end of the water inlet pipe (28) is connected to the output end of the solenoid valve unit 2 (27); a drainage pipe 2 (30) is installed at the output end of the water box 2 (29), and one end of the drainage pipe 2 (30) passes through the top inner wall of the water box 1 (24).

8. The pneumatic forging hammer with automatic lubrication function according to claim 1, characterized in that: A temperature sensing unit (17) is installed on the inner wall of the bottom of the guide frame (9), and the temperature sensing unit (17) is connected to the control unit (4) via an electrical signal.

9. A method for using a pneumatic forging hammer with automatic lubrication function according to any one of claims 1 to 8, characterized in that: The method of using the pneumatic forging hammer with automatic lubrication function is as follows: S1. Place the product on the support platform (2), and then use the connecting rod (7) to drive the hammer body (8) to move up and down to forge the product; S2, the oil in the oil storage box (12) flows into the guide frame (9) to lubricate the connecting rod (7), and at the same time, the lubricating oil deposited in the guide frame (9) is sucked back into the oil storage box (12) by the pump 1 (14); S3. During the forging process of the hammer body (8), the dustproof frame 1 (10) and the dustproof frame 2 (11) prevent foreign matter from entering the guide frame (9) and contaminating the lubricating oil in the guide frame (9). When the temperature of the lubricating oil in the guide frame (9) rises to a set value, the pump 2 (25) pumps the water in the water box 1 (24) into the water box 2 (29) to cool the guide frame (9), thereby cooling the lubricating oil in the guide frame (9).

10. The method for using the pneumatic forging hammer with automatic lubrication function according to claim 9, characterized in that: The step S2 also includes the following steps: S21, the brush (23) moves back and forth to clean the filter plate (21), so as to prevent impurities on the filter plate (21) from clogging the filter plate (21).
