Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe opening, in particular to a pipe opening and cutting device. BACKGROUND

[0002] In the field of pipe processing, cutting and opening are two very common and key processes. The traditional pipe processing method often takes cutting and opening as independent operation links, which need to be completed by using different equipment respectively. This not only increases the equipment purchase cost, but also occupies a large amount of production space. Moreover, in the process of transferring the pipe between different equipment, the pipe is easily damaged due to improper handling, affecting the product quality.

[0003] The existing pipe cutting equipment is not accurate enough in positioning and conveying the pipe during cutting, and the pipe often deviates, resulting in low cutting precision and uneven cutting surface, which increases the difficulty and cost of subsequent processing. At the same time, there is no effective collection device for the cutting waste, which is easy to scatter around the equipment, affecting the working environment and possibly damaging the equipment, shortening the service life of the equipment.

[0004] In terms of pipe opening, the current opening equipment often uses external clamps to fix the pipe. This fixing method is prone to cause deformation of the inner wall of the pipe during the opening process, affecting the quality and use performance of the pipe. Moreover, the existing opening equipment is relatively cumbersome to operate when opening different wall surfaces of the pipe, as it needs to adjust the position and fixing method of the pipe again, which reduces the production efficiency.

[0005] Therefore, the present application provides a pipe opening and cutting device to solve the problem of pipe deformation caused by pressure during the opening process of the existing processing device. SUMMARY

[0006] The purpose of the present application is to provide a pipe opening and cutting device to solve the problem of pipe deformation caused by pressure during the opening process of the existing processing device.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Reference Figures 1-9 A pipe opening and cutting device includes a support base 1.

[0041] A linear drive mechanism 2 is provided on one side of the support base 1 for transmitting pipe material for drilling; an drilling assembly 3 is provided on the other side. A sliding groove 101 is provided on the end face of the support base 1, and the sliding groove 101 is located between the linear drive mechanism 2 and the drilling assembly 3.

[0042] A sliding block 201 is fixed to the output end of the linear drive mechanism 2. The bottom of the sliding block 201 is slidably connected to the sliding groove 101. The sliding block 201 is an L-shaped block with its L-shaped opening facing the opening assembly 3. A support plate 202 is slidably connected to one side wall of the L-shaped opening of the sliding block 201 to support the cut pipe. A fixing plate 204 is fixedly connected to one side wall of the L-shaped opening of the sliding block 201, and the fixing plate 204 is located below the support plate 202. A cylinder 203 is provided below the fixing plate 204. The fixed end of the cylinder 203 is fixed to the fixing plate 204, and its output end passes through the fixing plate 204 and is fixed to the support plate 202, driving the support plate 202 to slide.

[0043] When the cut pipe is above the support plate 202, the linear drive mechanism 2 is activated to drive the sliding block 201 to slide, and the sliding block 201 drives the support plate 202 and the pipe to slide towards the opening assembly 3.

[0044] A cutting assembly 4 is fixed above the support base 1. The cutting assembly 4 includes several support frames 401. The several support frames 401 are mounted and fixed above the support base 1. A cutting chamber 402 is fixed on the several support frames 401 together, so that the sliding space of the support plate 202 is maintained between the cutting chamber 402 and the sliding groove 101.

[0045] The bottom of the cutting chamber 402 is provided with a discharge port 403 corresponding to the sliding groove 101, and the discharge port 403 is used for dropping the cut pipe. The top of the cutting chamber 402 is provided with a feed port 404, and a protective shell 5 is fixed to the outside of the feed port 404. The protective shell 5 covers the outside of the entire cutting device and is used to protect the device.

[0046] Two symmetrically arranged conveyor rollers 501 are rotatably connected above the protective shell 5 near the linear drive mechanism 2, with a distance between the two conveyor rollers 501 for conveying the pipe to be processed.

[0047] Two guide plates 502 are provided on the side of the conveying roller 501 near the opening assembly 3. The two guide plates 502 are fixed on both sides of the feed inlet 404 to guide the pipe material above the cutting chamber 402.

[0048] A limiting plate 503 is fixed to the side of the guide plate 502 away from the conveying roller 501. The limiting plate 503 is U-shaped, and the recessed opening of the limiting plate 503 corresponds to the position and size of the feed port 404, which is used to limit the conveying distance of the pipe to be processed.

[0049] The cutting chamber 402 is provided with a mounting plate 405 on the side near the linear drive mechanism 2. The side wall of the mounting plate 405 is slidably connected to a cutting saw blade 406 via an electric guide rail 4051. The cutting saw blade 406 is arranged perpendicularly to the feed inlet 404 and its rotation is controlled by a rotary drive 407.

[0050] The protective shell 5 has a cutting groove 504 arranged at 90° to the feed inlet 404. The cutting groove 504 passes through the feed inlet 404, and the cutting saw blade 406 slides within the cutting groove 504.

[0051] The rotary drive 407 can be an electric motor, and the linear drive mechanism 2 can be a cylinder.

[0052] The pipe to be processed is placed between two conveying rollers 501. By starting the conveying rollers 501, the friction between the two conveying rollers 501 and the surface of the pipe drives the pipe to move towards the cutting saw blade 406. During the movement of the pipe, the guide plate 502 and the limiting plate 503 prevent the pipe from deviating during conveying and cutting. When the position of the pipe to be cut coincides with the position of the cutting groove 504, the conveying rollers 501 are turned off and the rotary drive 407 is started to drive the cutting saw blade 406 to rotate. The electric guide rail 4051 drives the cutting saw blade 406 to move towards the pipe, thereby cutting the pipe.

[0053] The cut pipe enters the cutting chamber 402 through the feed port 404 and falls from the cutting chamber 402 onto the support plate 202.

[0054] The opening assembly 3 includes a second support plate 301, which is fixed to the side wall of the support base 1. The second support plate 301 is fixed with the fixed end of the second cylinder 302 on the side near the linear drive mechanism 2. The output end of the second cylinder 302 is fixed with a mounting cover 303. The mounting cover 303 is provided with a mounting groove 304 on the side away from the second cylinder 302.

[0055] The mounting groove 304 is provided with a meshing gear 305 and a gear 306 arranged vertically. The gear 305 is located below the gear 306. A reduction motor 308 is provided on the side of the gear 305 away from the cylinder 302. The fixed end of the reduction motor 308 is fixed to the support base 1, and the output end is fixed to the center of the end face of the gear 305, driving the gear 305 to rotate the gear 306. A mating groove 307 is provided through the center of the end face of the gear 306, and the diameter of the mating groove 307 is adapted to the outer diameter of the pipe.

[0056] When gear 1 305 drives gear 2 306 to rotate, gear 2 306 drives mating groove 307 to rotate, thereby driving the pipe located inside mating groove 307 to rotate.

[0057] Two symmetrically arranged sliding guide rails 309 are fixed above the support base 1. The two sliding guide rails 309 are located on the side of the cutting chamber 402 near the opening assembly 3. A connecting plate 310 is slidably connected between the two sliding guide rails 309. A bearing hole 311 is opened through the center of the end face of the connecting plate 310. A bearing is installed in the bearing hole 311. A clamping rod 312 is rotatably connected in the bearing. The clamping rod 312 and the mating groove 307 are located on the same axis.

[0058] The middle section of the clamping rod 312 is rotatably connected within the connecting plate 310. A support shaft 3121 is fixed at the center of one end of the clamping rod 312 near the mating groove 307. The outer diameter of the support shaft 3121 is smaller than that of the clamping rod 312. A limit rod 315 is fixedly connected to the other end of the support shaft 3121. The outer diameter of the limit rod 315 is the same as that of the clamping rod 312. A sleeve 3126 is sleeved on the support shaft 3121. The sleeve 3126 slides on the support shaft 3121. Four hinged arms 3122 are hinged to the outer wall of the sleeve 3126. The four hinged arms 3122 are arranged in a circle with their centers relative to the axis of the sleeve 3126. An L-shaped bent top plate 3123 is hinged to the other end of each of the four hinged arms 3122.

[0059] By changing the included angle of the hinge arm 3122, the top plate 3123 translates in the direction of the hinge arm 3122 that is hinged to it. When the edges of two adjacent top plates 3123 are in contact, the cross-section of the four top plates 3123 forms a rectangle. As the hinge arm 3122 drives the top plate 3123 to translate, as the distance between two adjacent top plates 3123 increases, the area of ​​the rectangle formed by the four top plates 3123 increases accordingly.

[0060] Each of the top plates 3123 has a sliding interlayer 3127 on both sides away from the bend. A movable plate 3128 is slidably connected in each sliding interlayer 3127. A miniature push rod 3129 is fixed between the movable plate 3128 and the top plate 3123. The miniature push rod 3129 is located at the bottom of the sliding interlayer 3127 and is used to drive the movable plate 3128 to slide. Each movable plate 3128 has a semi-circular hole 3124 at the edge of the opening of the movable plate 3128. Two adjacent semi-circular holes 3124 are fixed and form a circular hole.

[0061] By activating the micro push rod 3129, the micro push rod 3129 drives the moving plate 3128 to move relative to the top plate 3123. The top plate 3123 moves away from the sleeve 3126 until it abuts against the inner wall of the pipe, so that the inner wall of the pipe will not deform due to pressure during the drilling process.

[0062] The clamping rod 312 has several through holes 3125 arranged in a central array on its end face. The through holes 3125 pass through both ends of the clamping rod 312. A collection cylinder 316 is fixed to one end of the clamping rod 312 away from the support shaft 3121. An air pump 317 is fixed to one end of the collection cylinder 316 away from the clamping rod 312. The air pump 317 passes through the collection cylinder 316 and is located inside it. A filter screen is provided at the output port of the air pump 317 to prevent waste from entering.

[0063] The air pump 317 performs work to draw the waste debris in the through hole 3125 into the collection cylinder 316.

[0064] A connecting seat 313 is provided on the side of the gear 306 away from the reduction motor 308. The gear 306 passes through the mounting cover 303 and is rotatably connected to the connecting seat 313. The connecting seat 313 is located above the sliding guide rail 309 and is slidably connected. A drilling device 314 is fixed above the connecting seat 313.

[0065] The linear drive mechanism 2 drives the pipe to move toward the opening assembly 3. During the movement, the pipe first passes through the mating groove 307 and the limiting rod 315 is placed inside the pipe. As it continues to move, when the clamping rod 312 is inside the pipe and the circular hole reaches the position where the pipe needs to be opened, the micro push rod 3129 is activated to make the top plate 3123 abut against the inner wall of the pipe, and the drilling device 314 is activated to drill the pipe.

[0066] During the drilling process, the air pump 317 is activated to suck the waste material generated during drilling into the collection cylinder 316.

[0067] The drilling device 314 includes two fixing plates 3141, which are fixed above the connecting seat 313. The two fixing plates 3141 are arranged in parallel and located on both sides of the gear 306. Each fixing plate 3141 is fixed with an electric guide rail 3142 on the side near the gear 306. The two electric guide rails 3142 are slidably connected to the mounting seats 3143. An electric drill bit 3144 is installed below the mounting seats 3143 and is located directly above the pipe moving path.

[0068] When the pipe needs to be drilled, the movement of the pipe is stopped, the electric drill 3144 and the electric guide rail 3142 are started, and the mounting base 3143 and the electric drill 3144 are moved toward the pipe. After the electric drill 3144 contacts the pipe, the pipe is drilled.

[0069] Working principle: When it is necessary to cut the pipe and drill holes in the cut pipe, the pipe to be processed is placed between two conveying rollers 501. By starting the conveying rollers 501, the friction between the two conveying rollers 501 and the surface of the pipe drives the pipe to move towards the cutting saw blade 406. During the movement of the pipe, the guide plate 502 and the limiting plate 503 prevent the pipe from deviating during the conveying and cutting process. When the position of the pipe to be cut coincides with the position of the cutting groove 504, the conveying rollers 501 are turned off and the rotary drive 407 is started to drive the cutting saw blade 406 to rotate. The electric guide rail 4051 drives the cutting saw blade 406 to move towards the pipe, thereby cutting the pipe.

[0070] The cut pipe enters the cutting chamber 402 through the feed port 404 and falls from the cutting chamber 402 onto the support plate 202.

[0071] The linear drive mechanism 2 drives the pipe to move towards the opening assembly 3. During the movement, the pipe first passes through the mating groove 307 and the limiting rod 315 is sleeved inside the pipe. As it continues to move, when the clamping rod 312 is inside the pipe and the circular hole reaches the position where the pipe needs to be opened, the micro push rod 3129 is activated. The micro push rod 3129 drives the moving plate 3128 to move relative to the top plate 3123. The top plate 3123 moves away from the sleeve 3126 until it abuts against the inner wall of the pipe, so that the inner wall of the pipe will not deform due to pressure during the opening process.

[0072] Start the electric drill bit 3144 and the electric guide rail 3142, and move the mounting base 3143 and the electric drill bit 3144 toward the pipe. After the electric drill bit 3144 contacts the pipe, it drills a hole in the pipe. During the drilling process, the air pump 317 is started to suck the waste generated by drilling into the collection cylinder 316.

[0073] When drilling is required on other walls of the pipe, the gear motor 308 is started to drive the gear 305 to rotate. When the gear 305 drives the gear 306 to rotate, the gear 306 drives the mating groove 307 to rotate, which in turn drives the pipe located inside the mating groove 307 to rotate, thereby realizing drilling on other walls of the pipe.

[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
