[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 work shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0028] Embodiment 1:

[0029] A cutting device for seamless pipe production includes a processing table 1, a cutting protection structure is installed on the top of the processing table 1, a conveying structure is installed in the middle of the left and right sides of the processing table 1, and a collection structure is installed in the middle of the back of the cutting protection structure.

[0030] The cutting protection structure includes a cutting adjustment unit and a support protection unit. The cutting adjustment unit is installed at the top of one end of the back of the support protection unit. The cutting adjustment unit includes an adjustment box 104. An asynchronous motor 105 is installed at the right end of the adjustment box 104. The output end of the asynchronous motor 105 is connected to an adjustment part 106. The outer surface of the adjustment part 106 is connected to a support rod 107. The middle of the bottom surface of the support rod 107 is installed with an electric push rod 108. The output end of the electric push rod 108 is installed with a cutting assembly 109. The support protection unit includes a protection door 101. The middle parts of the fronts of the two protection doors 101 are installed with handles 102 on the side close to each other. A support frame 103 is arranged on the back of the protection door 101.

[0031] The protection door 101 is installed at one end close to the front on the top surface of the processing table 1. The top of the support frame 103 is fixedly connected to the bottom surface of the adjustment box 104. The outer surface of one end of the back of the support rod 107 is slidably connected to the inside of the convex chute opened in the middle of the top surface of the adjustment box 104. The bottom end of the support frame 103 is fixedly connected to the middle of the back of the top surface of the processing table 1.

[0032] By setting up the cutting protection structure, when the asynchronous motor 105 is started to drive the adjusting part 106 to rotate, the distance between the two ends of the support rods 107, the electric push rods 108, and the cutting assembly 109 is adjusted by using the double-thread, so that the seamless pipe can be cut equidistantly better, and the equidistance between them can be adjusted better.

[0033] When performing equidistant adjustment cutting on the seamless pipe, start the asynchronous motor 105 to drive the adjusting part 106 to drive. The output end of the asynchronous motor 105 drives the double-threaded rod to rotate. The middle part of the outer surface of the double-threaded rod is rotationally connected to the rotating cylinder. One end of the back of a support rod 107 in the middle of the outer surface of the rotating cylinder is connected. One end of the back of the two support rods 107 close to the middle is connected to the two threaded cylinders close to the middle. The two threaded cylinders close to the middle are threadedly connected to the two opposite threads opened on the outer surface of the double-threaded rod close to the middle. The two support rods 107 close to the left and right ends are connected to the two threaded cylinders close to the left and right ends. The inside of the two threaded cylinders close to the left and right ends is threadedly connected to the two opposite threads opened on the outer surface of the double-threaded rod close to the left and right ends. And the pitch of the two opposite threads opened close to the left and right ends is greater than the pitch of the two opposite threads opened close to the middle. Thus, when the output end of the asynchronous motor 105 drives the adjusting part 106 to rotate, the distance between the support rods 107 can be effectively adjusted equidistantly, and thereby the cutting assembly 109 is adjusted equidistantly, so as to facilitate driving the cutting assembly 109 to descend by the electric push rod 108 to realize equidistant cutting of the seamless pipe. By using the transparent observation windows installed in the middle of the two protective doors 101, it is convenient to observe the cutting condition, and at the same time, it can effectively prevent the debris from splashing during the cutting process and causing harm to the staff.

[0034] Embodiment 2:

[0035] On the basis of Embodiment 1, the conveying structure includes a conveying frame 201. At the top of the mutually remote ends of the two conveying frames 201, a driving wheel 202 is installed. One end of the front of the driving wheel 202 is connected to a rotating motor 203. At the top of the middle part and the mutually close ends of the conveying frame 201, a driven wheel 204 is installed. The middle part of the conveying frame 201 is close to the top and is connected to a mounting block 205. In the middle of the bottom surface of the mounting block 205, a spring 206 is installed. One end of the spring 206 away from the mounting block 205 is connected to a support plate 207. The conveying frame 201 is fixedly installed in the middle of the left and right sides of the processing table 1. The rotating motor 203 is detachably connected to the conveying frame 201. The support plate 207 is fixedly connected to the middle part of the outer surface of the conveying frame 201. The mounting block 205 is connected to the driven wheel 204 in the middle of the conveying frame 201. The driven wheel 204 in the middle of the conveying frame 201 is slidably connected to the inner wall of the chute opened in the middle of the conveying frame 201.

[0036] The collection structure includes a dust suction hopper 301. In the middle of the back surface of the dust suction hopper 301, a dust suction pipe 302 is installed. One end of the dust suction pipe 302 away from the dust suction hopper 301 is connected to a collection box 303. Inside the collection box 303, a collection drawer 304 is installed. Near the bottom of the middle part of the back surface of the dust suction hopper 301, an air pump 305 is installed. The outer surface of the dust suction hopper 301 is connected to the inside of a rectangular through hole opened in the middle of the front surface of the support frame 103 near the bottom. The outer surface of the collection drawer 304 is in sealed sliding connection with the inner wall of a rectangular hole opened in the middle of the right side of the collection box 303.

[0037] Through the settings of the conveying structure and the dust suction structure, the rotating motor 203 drives the driving wheel 202 to rotate and cooperate with the two driven wheels 204, so as to ensure the conveyance of the seamless pipe while ensuring the stability of its cutting. At the same time, when cutting, the air pump 305 is started to pump the air inside the collection box 303, so as to adsorb and collect the debris generated by cutting through the negative pressure state inside the collection box 303 via the dust suction pipe 302 and the dust suction hopper 301.

[0038] When conveying the seamless pipe, the driving wheel 202 and the two driven wheels 204 are arranged in a triangle, and at the same time, the arc grooves opened on the outer surfaces of the driving wheel 202 and the driven wheels 204 are used to guide and limit the seamless pipe. Then, when the rotating motor 203 is started to drive the driving wheel 202 to rotate, the seamless pipe can be stably conveyed, and at the same time, a stable supporting force can be provided for the seamless pipe during cutting, so as to ensure the stability during the cutting process of the seamless pipe. During the cutting process, the air pump 305 is started to pump the air inside the collection box 303, so that the inside of the collection box 303 presents a negative pressure state, and the debris generated by cutting is adsorbed by the negative pressure via the dust suction pipe 302 and the dust suction hopper 301. After the debris enters the inside of the collection box 303 through the dust suction hopper 301 and the dust suction pipe 302, several filter nets installed at the bottom of the collection drawer 304 are used to collect the debris, which is convenient for centralized treatment.
