DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] The stop valve includes a two-way stop valve and a three-way stop valve. The utility model can be used for both a two-way stop valve and a three-way stop valve. Taking a two-way stop valve as an example, Figure 6 and Figure 7 As shown, a pipe nut end 71 is provided on one side of the stop valve 7, one end of the stop valve 7 is a valve cap end 73, and the other end of the stop valve 7 is a welding end 74. The copper tube 8 is inserted into the welding end 74, and then the copper tube 8 is fixed to the welding end 74 by welding. A mounting plate 72 is fixedly provided on the outer side of the stop valve 7 near the welding end 74, and two symmetrically distributed mounting holes are provided on the mounting plate 72.

[0026] like Figure 1 and Figure 2 As shown, the utility model provides a cutting device for scrapped stop valves, including a workbench 1, on which a frame 11 is fixedly installed by bolts, on which a cutting mechanism 2 is fixedly arranged, and the workbench 1 is located directly below the cutting mechanism 2 and a clamp 3 is fixedly installed by bolts, and the cutting mechanism 2 cooperates with the clamp 3 to cut the scrapped stop valve 7 placed on the clamp 3.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, on the basis of the above embodiment, further, the cutting mechanism 2 includes a hydraulic cylinder 21, which is vertically distributed and fixedly installed on the frame 11 by bolts, and the piston rod end of the hydraulic cylinder 21 is fixedly installed with a tool holder 22 by bolts, and a blade 23 is fixedly installed on the tool holder 22 by bolts, so that when the blade 23 is damaged or needs to be polished, it is easy to replace and the debugging time is short. Among them, the blade 23 and the clamp 3 are both made of alloy tool steel materials; and the blade 23 and the clamp 3 need to be processed by quenching process, and the quenching process improves their hardness and wear resistance and increases their service life.

[0028] like Figure 1 , Figure 4 and Figure 5As shown, on the basis of the above embodiment, further, a placement groove 31 for placing the stop valve 7 is provided on the fixture 3, a pipe nut end groove 32 for placing the pipe nut end 71 of the stop valve 7 is provided at the bottom position near one end of the placement groove 31, and a guide groove 34 is provided at the other end of the placement groove 31, and the guide groove 34 facilitates the blade 23 to cut the copper tube 8. The fixture 3 is provided with a limiting groove 33 for placing the mounting plate 72 of the stop valve 7 between the pipe nut end groove 32 and the guide groove 34, and the width of the limiting groove 33 is slightly greater than the thickness of the mounting plate 72, so that the limiting groove 33 has a limiting effect on the stop valve 7, avoiding the stop valve 7 from turning over during the cutting process, and ensuring the stability of the cutting. The fixture 3 is provided with a shearing portion 35 at the position of the guide groove 34, and the shearing portion 35 can cooperate with the blade 23 to help cut the copper tube 8. A lower hopper 4 is fixedly provided on the workbench 1 near the guide groove 34 , and the lower hopper 4 is convenient for recycling the copper tube 8 after cutting. The lower hopper 4 transports the copper tube 8 cut and separated from the scrapped stop valve 7 to the collection device.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, on the basis of the above embodiment, further, a grating sensor 5 is fixedly provided at one end of the workbench 1 located at the cutting mechanism 2. When a human body is located between the grating sensors 5, the cutting mechanism 2 does not work to ensure safety. A protective cover 6 is fixedly provided at the other end of the workbench 1 located at the cutting mechanism 2. The protective cover 6 covers the workbench 1 to prevent materials from splashing and injuring people during the cutting process, and to prevent people from accidentally entering the cutting device when it is working and causing injuries.

[0030] like Figures 1 to 7 As shown, during work, the staff places the scrapped stop valve 7 to be cut in the placement groove 31 of the fixture 3 with their bare hands, and at the same time places the pipe nut end 71 of the scrapped stop valve 7 in the pipe nut end groove 32 of the fixture 3, places the mounting plate 72 of the scrapped stop valve 7 in the limit groove 33 of the fixture 3, and makes the copper tube 8 at the welding end 74 of the scrapped stop valve 7 correspond to the guide groove 34 of the fixture 3. When the staff's hand leaves the cutting mechanism 2 and the fixture 3, the grating sensor 5 senses that the human body has left the cutting device and transmits electrical information to the control machine. The control machine controls the hydraulic cylinder 21 to work, and the hydraulic cylinder 21 drives the blade 23 to move toward the direction of the fixture 3 to cut and separate the copper tube 8 at the welding end 74 of the scrapped stop valve 7 on the fixture 3. The separated copper tube 8 enters the collection device along the lower hopper 4, and then the staff takes the remaining scrapped stop valve 7 on the fixture 3 with their bare hands and throws them into the collection box, completing a working process of cutting the scrapped stop valve.
