Specific implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The cutting tools on existing cutting equipment are usually exposed. During the cutting process of the valve stem, the generated metal fragments are very likely to fly onto the staff, causing harm to the staff. At the same time, it also increases the risk of the staff coming into contact with the high-speed rotating tool, resulting in poor safety during the use of the equipment.

[0022] To solve the defects existing in the above-mentioned cutting device during use, please refer to Figures 1-5 , a cutting device for the production of check valve stems provided by the present invention can prevent the metal fragments generated during cutting from flying onto the staff and improve the safety of equipment use. The cutting device is based on a processing table 1, including the processing table 1. On one side of the top of the processing table 1, a protective box 2 is installed. Inside the protective box 2, a cutting mechanism 3 for cutting the valve stem is provided. The cutting mechanism 3 is arranged inside the protective box 2. During cutting, the processing end of the valve stem can be extended into the protective box 2 for cutting. The protective box 2 can block the metal fragments generated during processing to prevent the metal fragments from flying onto the staff. At the middle position of the top of the processing table 1, a pressing mechanism 9 for fixing the valve stem is provided. The pressing mechanism 9 can ensure the stability of the valve stem during the cutting process. And a cutting groove 4 is opened on the processing table 1. The cutting groove 4 is communicated with the protective box 2, and an inclined mesh plate 5 is fixedly installed inside the cutting groove 4. A waste box 7 is slidably connected to the bottom of the processing table 1. The large valve stem waste cut off can fall on the inclined mesh plate 5 and roll into the waste box 7 along the inclined mesh plate 5. The valve stem waste is uniformly collected through the waste box 7, while the metal fragments can pass through the inclined mesh plate 5 and fall into the cutting groove 4, realizing the separate collection of metal fragments and valve stem waste, which is convenient for recycling the two.

[0023] To facilitate the observation of the state of the valve stem inside the protective box 2, the protective box 2 is made of transparent tempered glass, and one side of the protective box 2 is hinged with a transparent protective door. A perforation for the valve stem to pass through is also provided on the protective box 2. The processing end of the valve stem is inserted into the protective box 2 through the perforation, and the valve stem is cut inside the protective box 2. The staff can directly observe the valve stem from the outside of the protective box 2, which is convenient for adjusting the position of the valve stem and observing the processing state of the valve stem. The device of the protective door facilitates the staff to repair the cutting mechanism 3.

[0024] Since the valve stem waste needs to roll from the inclined mesh plate 5 into the waste box 7, a blanking port 11 is provided on one side of the inner wall of the cutting groove 4. The valve stem waste can roll out from the blanking port 11. In order to prevent metal fragments from flying out of the blanking port 11, a dust-proof plate 6 for blocking the blanking port 11 is rotatably installed on one side of the processing table 1. During the cutting operation, the dust-proof plate 6 is in a closed state. When the valve stem waste drops after the cutting is completed, the valve stem waste can push open the dust-proof plate 6 by its own gravity. Subsequently, the dust-proof plate 6 can rotate downward and close by its own gravity to continue blocking the blanking port 11, which can prevent the metal fragments during cutting from flying out of the blanking port 11. And a door panel 8 is hinged on the other side of the inner wall of the cutting groove 4. Opening the door panel 8 facilitates the cleaning of the metal fragments collected in the cutting groove 4.

[0025] To realize the cutting operation of the valve stem, a hydraulic rod 31 fixedly installed on the inner top wall of the protective box 2 is provided. The free end of the hydraulic rod 31 extends into the interior of the protective box 2 and is fixedly connected with a suspension bracket 32. A blade 33 is rotatably installed inside the suspension bracket 32. And a servo motor 34 acting on the blade 33 is fixedly installed on one side of the hydraulic rod 31. Driving the servo motor 34 can drive the blade 33 to rotate, and the hydraulic rod 31 can drive the blade 33 to lift and lower, realizing the cutting operation of the blade 33. And the blade 33 is inside the protective box 2, which can also prevent the staff from contacting the high-speed rotating blade 33 and improve the safety of the equipment during use.

[0026] To realize the fixation of the valve stem, a bracket 91 fixedly installed on the top of the processing table 1 is provided. The inner top wall of the bracket 91 is threadedly connected with a threaded rod 92. The lower end of the threaded rod 92 is rotatably installed with a pressing plate 93. The middle part of the pressing plate 93 is arc-shaped. The pressing plate 93 is slidably installed between the two inner walls of the bracket 91. Rotating the threaded rod 92 drives the pressing plate 93 to slide downward, and the pressing plate 93 can tightly press the valve stem on the processing table 1, improving the stability of the valve stem during processing.

[0027] Refer to Figure 1 As shown in the figure, at least two groups of feeding rollers 10 are symmetrically installed on the top of the processing table 1. Along the feeding rollers 10, the valve stem can be inserted into the protective box 2 more accurately, and the smoothness of the valve stem entering the protective box 2 can also be improved, facilitating the feeding work of the valve stem.

[0028] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in this field. Moreover, the present utility model is mainly used to protect mechanical devices.
