[0025] Embodiment 1

[0026] The utility model provides Figure 1 - Figure 5 The cutting device for producing high-strength toughened modified PP material shown in the figure comprises a driving mechanism 1, a driving mechanism 2, a supporting mechanism 1 and a cutting and grinding mechanism 2, wherein the supporting mechanism 1 is used to support the pipe, the driving mechanism 1 is used to push the pipe to move along a straight line, and the driving mechanism 2 is used to drive the cutting and grinding mechanism 2 to move in a straight line while cutting and grinding the pipe from the side to reduce the burr degree of the pipe cut. The driving direction of the driving mechanism 1 and the driving direction of the driving mechanism 2 are perpendicular to each other.

[0027] Here is an example. Both the driving mechanism 1 and the driving mechanism 2 can directly use a cylinder or a hydraulic cylinder, or a crank slider and other structures to achieve the driving purpose. Because the driving methods are various, this design will not be described in detail here, and the cylinder is used as an example for explanation.

[0028] The supporting mechanism 1 includes a base plate 11, a bracket 12 and a transmission roller 13. The base plate 11 is placed on the ground, and the bracket 12 is vertically fixed on the base plate 11. A plurality of transmission rollers 13 are rotatably connected in the bracket 12. The transmission rollers 13 are used to support the pipe while transmitting the pipe. Cylinder 1 is placed at one end of the bracket 12. Cylinder 1 includes a cylinder seat and a telescopic rod. The telescopic rod is used to push the pipe to move on the transmission roller 13. The cylinder seat is fixed on the bracket 12. A control unit for controlling the extension and retraction of the telescopic rod is arranged in the cylinder seat. The control unit is electrically connected to an external controller.

[0029] The height of the part of the support 12 above the transmission roller 13 is higher than the diameter of the pipe.

[0030] Preferably, the cross-sectional shape of the transmission roller 13 is V-shaped, so that the pipe can be located as much as possible in the middle of the transmission roller 13 during the transmission of the pipe, thereby improving the stability of the pipe transmission process.

[0031] The cutting and grinding mechanism 2 includes a mounting plate 21, a cutting blade assembly 22 and a grinding assembly 23. A cylinder 2 for pushing and pulling the mounting plate 21 is provided on one side of the mounting plate 21. The cylinder 2 includes a cylinder seat and a telescopic rod. The telescopic rod is fixedly connected to the mounting plate 21. The cylinder seat is fixed to the bracket 12. A control unit for controlling the telescopic rod is provided in the cylinder seat. The control unit is electrically connected to an external controller. The cutting blade assembly 22 and the grinding assembly 23 are provided on both sides of the mounting plate 21, respectively.

[0032] In this embodiment, an implementation method of the cutting knife assembly 22 is: the cutting knife assembly 22 includes a knife body 221, a blade edge 222 and a resistance wire 223. The knife body 221 is fixedly connected to the mounting plate 21, and the blade edges 222 are fixed on both sides of the knife body 221. An S-shaped resistance wire 223 is embedded in the knife body 221. The resistance wire 223 is connected to an external power supply and is used to generate heat after being powered on, so that when cutting the pipe, the high temperature can be used to soften the pipe, making it convenient for the blade edge 222 to cut into the pipe to complete the purpose of cutting the pipe.

[0033] In this embodiment, another implementation of the cutting knife assembly 22 is: the cutting knife assembly 22 includes a cutting line and a plurality of transmission wheels, a motor is installed above the mounting plate 21, a transmission wheel is fixedly connected to the output shaft of the motor, and a plurality of transmission wheels are rotatably connected inside the mounting plate 21, and the transmission wheels are connected through the cutting line transmission. In this way, when the motor is turned on, the motor drives the cutting line to rotate and cut the pipe, and the purpose of cutting the pipe can also be achieved.

[0034] The grinding assembly 23 includes a grinding layer 231 and a grinding plate 232. The grinding layer 231 is detachably connected to the end surfaces of both sides of the grinding plate 232. Both ends of the grinding plate 232 are provided with guide surfaces. After being cut, if the distance between the two sections of the pipe is close, the guide surface can easily enter the gap between the two sections of the pipe and squeeze the pipe to both sides from the middle, and fix the position of the pipe by squeezing, so as to ensure the grinding effect of the grinding plate 232 on the end surface of the pipe.

[0035] In summary, the technical solution of this embodiment can be summarized as follows: turn on cylinder one, which pushes the pipe to move to the specified position on the support mechanism 1. At this time, the end of the pipe is located on the moving path of the grinding assembly 23. After fixing the position of the telescopic rod of cylinder one, turn on cylinder two, and the telescopic rod of cylinder two pushes the mounting plate 21 to move. While the mounting plate 21 drives the cutting knife assembly 22 to cut the pipe, the grinding assembly 23 grinds the end face of the pipe. Here, because the pipe is blocked by the brackets 12 on both sides, it will not fall off the support mechanism 1 even if it is subjected to radial push and pull forces. Then, drive cylinder two to move to the outside of the support mechanism 1, and cylinder one continues to push the pipe forward. Then repeat the above process. The grinding assembly 23 can repeatedly grind the end face after cutting by the cutting knife assembly 22 to reduce the degree of burrs on the rear end face after thermal cutting.

[0036] Embodiment 2

[0037] On the basis of the above-mentioned embodiment, the device further comprises a blocking component 3, which is used together with the cutting and grinding mechanism 2 to grind the two end faces of the cut pipe.

[0038] One solution in the present embodiment is: the blocking component 3 includes a gantry 31, a swing plate 32, a plate body 1 33 and a plate body 2 34, the bottom plate 11 and the gantry 31 are fixedly connected, and the swing plate 32 is hinged in the gantry 31, and the swing plate 32 is located on the outside of the output end of the bracket 12, and the mounting plate 21 is fixedly connected through the plate body 1 33 and the plate body 2 34. When the cutting knife assembly 22 performs thermal cutting and the grinding assembly 23 starts grinding, the plate body 2 34 moves synchronously with the mounting plate 21 to block the swing plate 32 from opening. At this time, the grinding plate 232 can grind the end face of the pipe while opening the pipe, and then the telescopic end of the cylinder 2 drives the mounting plate 21 to reset, the cutting knife assembly 22 and the grinding assembly 23 leave the pipe, and the plate body 2 34 leaves the swing plate 32. At this time, the cylinder 1 pushes the pipe to move, and the grinded end of the pipe will push open the swing plate 32 and detach from the support mechanism 1, completing the purpose of automatic unloading after grinding.

[0039] Another scheme in this embodiment is: the blocking component 3 includes a gantry 31, a swing plate 32, a plate body 1 33 and a plate body 2 34, the bottom plate 11 and the gantry 31 are fixedly connected, and the swing plate 32 is hinged in the gantry 31, and the swing plate 32 is located on the output outer side of the bracket 12, the plate body 1 33 is a wedge block 1, and the mounting plate 21 is elastically slidably connected with the plate body 24, and the plate body 24 is a wedge block 2, and the wedge block 1 and the wedge block 2 slide and contact each other. When the cutting knife assembly 22 cuts the pipe and the grinding assembly 23 grinds the end face of the pipe, the plate body 1 33 squeezes the plate body 2 34, and the plate body 2 34 moves up to prevent the swing plate 32 from opening; when the cutting knife assembly 22 and the grinding assembly 23 leave the pipe, the plate body 2 34 resets and moves down under the action of the elastic force, and the plate body 2 34 leaves the swing plate 32. At this time, the cylinder 1 pushes the pipe to move, and the polished pipe can be pushed off the support mechanism 1.

[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
