[0003] The existing Chinese patent CN113695683B discloses a cutting device for machining mechanical parts. After the plate to be processed is clamped and fixed by a fixed plate, the mounting frame is pushed to drive the blade to move to the right to cut the plate to be processed. In the cutting process, the extrusion pump can also be triggered to run, so that the oil spray head can be coated with oil on the cut end face of the plate to prevent the cut surface of the carbon alloy plate from being easily oxidized by the environment and rusting. However, since the oil spray head of the device is located on the left side of the blade, and the auxiliary rod will continuously engage with the slot on the top surface of the baffle end regardless of whether it moves to the left or right with the mounting frame, the oil spray head will still spray oil under the action of the auxiliary rod during the process of the mounting frame driving the blade to move to the left and reset, resulting in a large amount of oil waste, and there are defects during use.

[0023] Two symmetrically distributed air bags 11 are installed on the lower side of the pressure plate 9, and end covers 12 are fixedly connected to both ends of the air bags 11.

A rubber valve 17 is fixedly embedded in the interior of the oil outlet pipe 14 near its lower end. The rubber valve 17 is used to prevent the oil in the oil outlet pipe 14 from flowing out. A support plate 18 is installed on the lower side of the airbag 11, and the connection between the support plate 18 and the knife seat 3 is a fixed connection. An avoidance groove is opened on the support plate 18 corresponding to the wire rope 6. The end covers 12 located at both ends of the airbag 11 are respectively fixedly connected to the pressure plate 9 and the support plate 18. Four pins 21 are fixedly embedded on the upper end of the support plate 18, and the pins 21 penetrate the pressure plate 9. A spring 22 is movably sleeved on the outer side of the pin 21, and the two ends of the spring 22 are movably abutted against the pressure plate 9 and the support plate 18 respectively.

[0025] A connecting plate 23 is installed on the lower side of the wire rope 6, and a bracket 32 ​​is installed on the lower side of the cutting table 1, and the connection between the bracket 32 ​​and the support frame 2 is a fixed connection. Limit rods 33 are movably sleeved at the four corners of the connecting plate 23, and the connection between the limit rod 33 and the bracket 32 ​​is a fixed connection. The limit rod 33 is used to limit the moving direction of the connecting plate 23. Two symmetrically distributed springs 34 are fixedly installed on the lower end of the connecting plate 23, and the lower end of the spring 34 is movably abutted against the bracket 32.

[0026] The driving assembly includes an articulated seat 24, and the number of the articulated seats 24 is two groups, and they are symmetrically distributed. A push rod 25 is installed on the inner side of the articulated seat 24, and the push rod 25 is rotatably connected to the articulated seat 24 through a positioning shaft 26. The cross-sectional shape of the push rod 25 is circular, and two symmetrically distributed coil springs 27 are movably sleeved on the outer side of the positioning shaft 26, and the outer end of the coil spring 27 is fixedly connected to the articulated seat 24. The left side of the push rod 25 is movably abutted against a baffle 28.

[0027] The baffle plate 28 and the hinge seat 24 are an integrally formed structure, the right side of the hinge seat 24 is in an open state, a ball 29 is movably embedded in the upper end of the push rod 25, a fixing plate 30 is fixedly embedded at the lower end of the cutting table 1 corresponding to the positioning axis 26, a plurality of triangular blocks 31 equidistantly distributed are fixedly installed at the lower end of the fixing plate 30, and the cross-sectional shape of the triangular block 31 is a right triangle, the vertical side of the triangular block 31 is located on the right side of the hypotenuse, the connection between the ball 29 and the triangular block 31 is rolling contact, and the ball 29 is used to reduce the friction resistance between the push rod 25 and the triangular block 31.

[0028] Working principle: When cutting the carbon alloy plate, the support frame 2 drives the blade 5 to move to the right, and the motor 4 drives the blade 5 to rotate counterclockwise to cut the carbon alloy plate. When the top rod 25 moves to the right with the bracket 32, the top rod 25 will be blocked by the baffle 28, so that the ball 29 at the upper end of the top rod 25 will slide along the bevel of the triangular block 31. Driven by the triangular block 31, the top rod 25 will drive the connecting plate 23 to move downward, and the connecting plate 23 will be brought by the steel wire rope 6. The movable pressure plate 9 moves downward, and the pressure plate 9 will squeeze the airbag 11 after moving downward, so that part of the oil in the airbag 11 will break the rubber valve 17 and be discharged from the oil outlet pipe 14. When the ball 29 passes through the vertical edge of the triangular stopper 31 and leaves the triangular stopper 31, the connecting plate 23 and the pressure plate 9 will move back and reset under the compression force of the spring 2 34 and the spring 1 22 respectively. During the process of the pressure plate 9 moving back, the airbag 11 is restored, and a certain amount of oil is sucked out from the oil tank 16 through the conduit 13. When the blade 5 finishes cutting the carbon alloy plate, the support frame 2 moves back to the left and resets. During this process, the push rod 25 will be blocked by the vertical edge of the triangular block 31. Since the right side of the hinge seat 24 is in an open state, the push rod 25 will rotate to the right under the obstruction of the triangular block 31 to avoid the triangular block 31, and will not cause the connecting plate 23 and the pressure plate 9 to move downward. Therefore, the oil in the airbag 11 will not be squeezed out at this time, so that during the process of the blade 5 moving back and resetting, the oil outlet pipe 14 will not discharge oil, which can effectively avoid oil waste.

[0029] Example 2: Please refer to Figure 5 , Figure 7 , Figure 8 This embodiment further explains Example 1. A funnel 19 is movably sleeved on the outside of the wire rope 6, and the connection between the funnel 19 and the support plate 18 is a fixed connection. The funnel 19 is made of a flexible material. The funnel 19 is used to concentrate the oil to the outside of the wire rope 6, and an opening 20 is provided on the funnel 19.

[0030] In this embodiment: when the push rod 25 moves to the right and contacts the multiple triangular stoppers 31, the connecting plate 23 drives the steel wire rope 6 and the pressure plate 9 to move up and down reciprocatingly, and the pressure plate 9 moves down to discharge a certain amount of oil from the oil outlet pipe 14, and the oil is discharged into the funnel 19. Under the action of the funnel 19, the oil flows along the steel wire rope 6 to the brush part 7. The brush part 7 moves up and down reciprocatingly in the process of moving to the right, and can smear the oil on the cut surface of the carbon alloy plate, which is conducive to the uniform distribution of the oil on the cut surface of the carbon alloy plate. When the brush portion 7 of the wire rope 6 is worn and needs to be replaced, the personnel slightly moves down the pressure plate 9 to disengage the ring 8 at the upper end of the wire rope 6 from the hook 10 at the lower end of the pressure plate 9, and then disengages the ring 8 at the lower end of the wire rope 6 from the hook 10, and then moves the wire rope 6 out of the funnel 19 through the opening 20 on the flexible funnel 19, and finally pulls the wire rope 6 out of the cutting groove on the upper side of the cutting table 1, and then a new wire rope 6 can be installed.

[0031] Example 3: Please refer to Figure 5 , Figure 6 The present embodiment further explains the first embodiment, a material receiving assembly is installed between the wire rope 6 and the connecting plate 23, and the material receiving assembly includes a round tube 35 fixedly embedded in the center of the upper end of the connecting plate 23, and an oil receiving pan 36 is fixedly connected to the upper end of the round tube 35. The oil receiving pan 36 is used to prevent the oil on the wire rope 6 from dripping on the lower side of the cutting table 1, and the oil receiving pan 36 is located on the upper side of the spring 1 22. The shape of the oil receiving pan 36 is conical, and a conical filter cover 37 is fixedly installed inside the oil receiving pan 36.

[0032] A hook 10 is also fixedly mounted on the upper end of the conical filter cover 37, and the conical filter cover 37 is used to filter out debris in the oil. A sleeve 38 is movably sleeved on the outer side of the circular tube 35 near its lower end, and the sleeve 38 passes through the bracket 32. The connection between the sleeve 38 and the bracket 32 ​​is a fixed connection. A collection bottle 39 is threadedly sleeved on the outer side of the sleeve 38, and the collection bottle 39 is located on the lower side of the bracket 32.

[0033] In the present embodiment, during the reciprocating movement of the steel wire rope 6, the oil will flow downward along the steel wire rope 6 into the oil receiving pan 36, and the conical filter cover 37 in the oil receiving pan 36 will filter the debris that may be carried by the oil, and the oil filtered by the conical filter cover 37 will flow into the collecting bottle 39 through the circular tube 35 and the sleeve 38. Driven by the triangular stopper 31, the connecting plate 23 first moves downward slowly, and then moves upward and reset instantly under the drive of the compression force of the spring 2 34, so that the connecting plate 23 will hit the top of the limit rod 33 after moving upward and resetting, which is not only conducive to the vibration of the oil receiving pan 36 to shake off the debris filtered out by the conical filter cover 37 and prevent the debris from clogging the mesh of the conical filter cover 37, but also conducive to the filtered oil to flow quickly into the collecting bottle 39.
