Description

Technical Field

[0001] This invention relates to the field of metal cutting equipment technology, specifically to an intelligent multi-functional metal tube fixed-length shearing machine. Background Technology

[0002] Metal pipe length shearing machines are widely used in pipe cutting, often for the mass production of building, pipeline, and structural pipes. Existing rotary shearing machines mainly consist of a frame, clamping device, rotary drive system, and cutting blades. During processing, the pipe is clamped and rotated, while the blade feeds radially to complete the cut. These machines have a relatively limited functionality, only capable of cutting pipes to a fixed length. Burrs and flaks formed at the pipe end after cutting cannot be processed on the same machine and must be transferred to specialized grinding equipment for secondary processing, increasing process flow time and labor costs. Furthermore, the centering accuracy of traditional clamping structures is limited, and the pipe axis is prone to misalignment with the spindle axis. The vibration during rotary cutting is significant, making it difficult to guarantee the flatness and perpendicularity of the end face, and the tool wears out quickly. In addition, the lack of automatic separation between the two sections after the pipe is cut causes the cut surfaces to press against each other, which makes subsequent end face processing and unloading inconvenient. Furthermore, the pipe needs to be rotated as a whole during cutting, while the two pipe sections need to be rotated independently during grinding. Existing equipment does not adequately consider the switching of drive modes under different working conditions, and is often complex in structure or difficult to control. To address the problems caused by the above-mentioned single function, this solution integrates an online grinding function on the basis of cutting, enabling the equipment to have the processing capability of both cutting and grinding processes at the same time, and optimizes the clamping and separation structure. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an intelligent, multi-functional metal pipe length-cutting machine. This machine utilizes a self-centering positioning and clamping structure, coupled with a linked support and clamping structure, to clamp the pipe fittings. It then cuts the pipe fittings using a pipe-cutting milling cutter module and incorporates a grinding mechanism to remove burrs from the cut ends after the pipe fittings are cut, thus achieving multi-functional processing capabilities.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions: The machine includes a frame and a tool assembly mounting bracket. The tool assembly mounting bracket is fixedly mounted on the frame and houses a pipe-cutting milling cutter module. The shearing machine also includes a positioning and clamping mechanism, a supporting and clamping mechanism, a feed extension unit, and a grinding mechanism. The positioning and clamping mechanism is mounted on the frame and located to the left of the tool assembly mounting bracket. The supporting and clamping mechanism is mounted on the frame and located to the right of the tool assembly mounting bracket. The feed extension unit is fixedly mounted on the rear inner wall of the tool assembly mounting bracket, and the pipe-cutting milling cutter module is fixedly mounted on the stepping end of the feed extension unit. The feed extension unit drives the pipe-cutting milling cutter module to feed in a direction perpendicular to the pipe axis to achieve the cutting action on the pipe. The grinding mechanism is mounted on the tool assembly mounting bracket and located between the positioning and clamping mechanism and the supporting and clamping mechanism. It is used to grind and deburr the cut end face of the pipe after cutting. The aforementioned positioning and clamping mechanism includes a positioning mounting frame, a positioning rotating seat, a panel seat, a tensioning assembly, positioning clamping claws, and a clamping hydraulic rod. The positioning mounting frame is fixedly mounted on the frame and located to the left of the tool assembly mounting frame. The positioning rotating seat is spun onto the side plate of the positioning mounting frame facing the tool assembly mounting frame via bearings, allowing the positioning rotating seat to rotate freely around its own axis. The panel seat is snap-fitted and fixedly mounted on the side port of the positioning rotating seat facing the tool assembly mounting frame, and the panel seat and the positioning rotating seat together enclose an internal mounting space. The tensioning assembly is located within this internal mounting space on the positioning rotating seat. The positioning clamping claws are fitted onto the tensioning assembly and are driven by the tensioning assembly to move radially. The clamping hydraulic rod is fixedly mounted on the positioning mounting frame and is fitted with the tensioning assembly. The clamping hydraulic rod drives the tensioning assembly to move, thereby causing the positioning clamping claws to clamp or release the pipe fitting. The aforementioned tensioning assembly includes a support slide rail, a tensioning stepper seat, a telescopic seat, a guide slide rail, and a guide slider. Several support slide rails are arranged at equal angles and fixedly mounted on the inner wall of the positioning rotary seat, extending radially along the positioning rotary seat. The tensioning stepper seat is slidably mounted on the support slide rails, allowing it to reciprocate along the support slide rails in the radial direction of the positioning rotary seat. The telescopic seat is located inside the positioning rotary seat, and is coaxial with the piston rod of the clamping hydraulic rod. It can reciprocate along the axial direction of the positioning rotary seat; there are several guide rails, and each guide rail is fixedly installed on the side wall of the telescopic seat at equal angles. The guide rails are inclined relative to the axis of the positioning rotary seat; the guide slider is fixedly installed on the opening and closing stepping seat, and the guide slider is slidably mounted on the guide rail; when the telescopic seat moves axially, the axial movement of the telescopic seat is converted into the radial sliding of the opening and closing stepping seat along the support rail through the sliding cooperation of the guide rail and the guide slider, thereby realizing the synchronous opening and closing movement of multiple opening and closing stepping seats; A fixed connecting seat is fixedly installed on the aforementioned telescopic seat, and a movable connecting seat is fastened and fixedly installed on the fixed connecting seat; a connecting rod is fixedly installed on the piston rod that clamps the hydraulic rod, and the connecting rod is axially movably inserted through the end plate of the positioning rotary seat. A limit connecting seat is fixedly installed on one end of the connecting rod that extends into the positioning rotary seat, and the limit connecting seat is clamped in the internal cavity formed by the fastening of the fixed connecting seat and the movable connecting seat, thereby realizing the axial connection between the piston rod that clamps the hydraulic rod and the telescopic seat; through the cooperation of the limit connecting seat with the fixed connecting seat and the movable connecting seat, the piston rod that clamps the hydraulic rod can drive the telescopic seat to move axially, and at the same time, when the positioning rotary seat rotates, the limit connecting seat can rotate relative to the fixed connecting seat and the movable connecting seat to avoid interference; The aforementioned opening and closing stepper seat is fixedly equipped with a guide seat, and a guide groove is opened on the end plate of the panel seat. The guide seat is slidably disposed in the guide groove, which guides and limits the sliding of the guide seat. The positioning clamping claw is disposed on the guide seat and is fixedly connected to the guide seat by bolts. The positioning clamping claw is movably abutted against the outer end face of the panel seat. When the opening and closing stepper seat slides radially, the guide seat drives the positioning clamping claw to move radially synchronously, thereby realizing the clamping and releasing of the pipe fitting. The positioning clamping claw is detachably connected to the guide seat by bolts, which facilitates the replacement of the corresponding clamping claw according to different pipe diameters. A centering plate is embedded in the end plate of the aforementioned panel base, and the centering plate is located at the center of the panel base. A centering rod is fixedly installed on the side wall of the centering plate facing the inside of the panel base. The centering rod extends axially, and the telescopic seat is movably sleeved on the centering rod. The centering rod guides and centers the axial movement of the telescopic seat. A countersunk sleeve is integrally formed on the panel base, and the countersunk sleeve protrudes into the panel base. A connecting threaded sleeve is fixedly installed on the inner side wall of the positioning rotary seat at a position corresponding to the countersunk sleeve. A connecting bolt passes through the countersunk sleeve and is screwed into the connecting threaded sleeve, thereby fixing the panel base and the positioning rotary seat together. A connecting end foot is integrally formed on the centering plate. The connecting end foot is sleeved on the connecting bolt and is clamped between the countersunk sleeve and the connecting threaded sleeve, thereby clamping and fixing the centering plate to the panel base. The aforementioned support and clamping mechanism includes a support rod, a stepping frame, a stepping hydraulic rod, a support mounting frame, a support rotating seat, and support clamping claws. The support rod is fixedly mounted on the frame and extends along the pipe conveying direction. The stepping frame is located inside the frame and movably sleeved on the support rod, allowing it to slide back and forth along the extension direction of the support rod. The stepping hydraulic rod is fixedly mounted on the frame, and its piston rod is fixedly mounted on the stepping frame, driving the stepping frame to slide along the support rod. The support mounting frame is fixedly mounted on the stepping frame, and the tool assembly mounting frame is located between the positioning mounting frame and the support mounting frame. The support rotating seat is spun onto the support mounting frame via bearings, and the support rotating seat and the positioning rotating seat are coaxial, allowing the support rotating seat to rotate freely around the same axis as the positioning rotating seat. Several support clamping claws are located inside the support rotating seat and are used to clamp the support end of the pipe. The aforementioned support clamping claw consists of two symmetrically arranged claws. One claw has a connecting arm symmetrically positioned on it. One end of the connecting arm is screwed onto the claw via a pivot, while the other end of the connecting arm is screwed onto a support arm via a pivot. The other end of the support arm is screwed onto the inner wall of the rotating support seat via a pivot. The linkage between the connecting arm and the support arm provides radial support and guidance for the claw. A telescopic threaded rod is screwed onto the rotating support seat via a bearing. A telescopic threaded sleeve is fixedly mounted on the claw, and the telescopic threaded rod is threaded into the sleeve. Rotating the telescopic threaded rod causes the sleeve to move axially via the threaded engagement, thereby causing the claw to open and close radially, thus clamping or releasing the pipe fitting. A rotary drive motor is fixedly mounted on the aforementioned positioning mounting bracket to provide rotational power. A spline sleeve is screwed onto the positioning mounting bracket via bearings. The spline sleeve is connected to the output shaft of the rotary drive motor via a coupling, and the rotary drive motor drives the spline sleeve to rotate. A positioning drive shaft is screwed onto the positioning mounting bracket via bearings. The positioning drive shaft is connected to the positioning rotary seat via a spur gear set, realizing the transmission of power from the positioning drive shaft to the positioning rotary seat. A positioning transmission shaft is screwed onto the positioning mounting bracket via bearings. One end of the positioning transmission shaft is connected to the positioning drive shaft via a bevel gear set, and the other end of the positioning transmission shaft is connected to the end shaft of the spline sleeve via a bevel gear set. Thus, the power of the rotary drive motor is transmitted sequentially through the spline sleeve, the positioning transmission shaft, and the positioning drive shaft to the positioning rotary seat, driving the positioning rotary seat to rotate. A spline shaft is screwed onto the support mounting bracket via bearings. One end of the spline shaft is axially movably inserted into the spline sleeve. The spline shaft and the spline sleeve transmit torque through a spline engagement, while the spline... The shaft can slide freely axially within the spline sleeve to accommodate the movement of the stepper frame. An overrunning clutch module is fixedly mounted on the support mounting bracket, and the end shaft of the splined shaft is drive-connected to the input shaft of the overrunning clutch module. A support drive shaft is spun onto the support mounting bracket via bearings, and the support drive shaft is drive-connected to the support rotating seat via a spur gear set. A support transmission shaft is spun onto the support mounting bracket via bearings, one end of which is drive-connected to the support drive shaft via a bevel gear set, and the other end of which is drive-connected to the output shaft of the overrunning clutch module via a bevel gear set. Through the above transmission chain, the power of the rotary drive motor can be selectively transmitted to the support rotating seat via the splined sleeve, splined shaft, overrunning clutch module, support transmission shaft, and support drive shaft, driving the support rotating seat to rotate. When the input shaft speed of the overrunning clutch module is less than the output shaft speed, the overrunning clutch is in a free state, and power is interrupted; when the input shaft speed is greater than or equal to the output shaft speed, the overrunning clutch is in a locked state, and power is transmitted. The aforementioned grinding mechanism includes a lifting hydraulic rod, a lifting stepper seat, a grinding drive motor, and a wire brush disc. The lifting hydraulic rod is fixedly mounted on the upper inner wall of the tool assembly mounting frame and is arranged vertically. The lifting stepper seat is fixedly mounted on the lower end of the piston rod of the lifting hydraulic rod and is driven by the lifting hydraulic rod to move vertically up and down. The grinding drive motor is fixedly mounted on the lifting stepper seat and moves synchronously with it. The wire brush disc is fixedly mounted on the output shaft of the grinding drive motor and is driven by the grinding drive motor to rotate, grinding the cut end face of the pipe fitting.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: This shearing machine clamps both ends of the pipe fitting using a positioning clamping mechanism and a support clamping mechanism, respectively. Stable rotation of the pipe fitting is achieved through coaxially arranged positioning and support rotating seats, working in conjunction with a pipe-cutting milling cutter module to complete high-precision cutting. After cutting, a grinding mechanism can grind and deburr the cut end face, achieving integrated shearing and grinding functions. The design of the stepping frame and stepping hydraulic rod allows for automatic separation of the cut pipe segments, providing space for grinding. The transmission system uses a spline sleeve and an overrunning clutch module, ensuring synchronous rotation of the pipe fitting during cutting and enabling independent rotation and grinding of both sides of the pipe fitting after cutting. The structure is compact and the transmission is reliable. The double slide rail guide and centering structure in the opening and closing assembly ensure automatic centering of the clamping and ease of changing the clamping jaws, thus expanding the applicability of the equipment.

The support mounting frame 6-4 is fixedly mounted on the stepping frame 6-2, and the support... Mounting bracket 6-4 is located on the right side of tool assembly mounting bracket 2. A supporting rotating seat 6-5 is screwed onto the supporting mounting bracket 6-4 via bearings. The supporting rotating seat 6-5 and the positioning rotating seat 4-2 are coaxially aligned. Two supporting clamping claws 6-6 are symmetrically arranged within the supporting rotating seat 6-5. Two connecting arms 21 are symmetrically screwed onto each supporting clamping claw 6-6 via a rotating shaft.

The grinding mechanism 8 includes a lifting hydraulic rod 8-1, a lifting stepper seat 8-2, a grinding drive motor 8-3, and a wire brush disc 8-4.

The grinding drive motor 8-3 is fixedly installed on the lifting stepper seat 8-2. The wire brush disc 8-4 is fixedly installed on the output shaft of the grinding drive motor 8-3.

[0019] When using this device, open the positioning clamping claw 4-4 and the supporting clamping claw 6-6, move the pipe cutting milling cutter module 3 backward and retract it, and raise and retract the lifting stepping seat 8-2. Then, feed the pipe fitting in from the right side of the device, so that the pipe fitting passes through the two opened supporting clamping claws 6-6 and the cutter assembly mounting bracket 2 in sequence and is inserted between the opened positioning clamping claws 4-4. Then, the clamping hydraulic rod 4-5 drives the connecting rod 11 to move. The connecting rod 11, through its cooperation with the fixed connecting seat 9 and the moving connecting seat 10, drives the telescopic seat 5-3 to move. The telescopic seat 5-3 then moves through its upper... The guide rail 5-4 cooperates with the guide slider 5-5 on the tensioning stepper seat 5-2, and guides the tensioning stepper seat 5-2 through the support rail 5-1, so that the telescopic seat 5-3 moves to the left and drives the tensioning stepper seat 5-2 to close. Thus, the tensioning stepper seat 5-2 drives the positioning clamping claw 4-4 to close through the guide seat 13, realizing the clamping and centering of the pipe fitting. After the positioning clamping claw 4-4 has clamped the pipe fitting, the telescopic threaded rod 23 is rotated. Through the cooperation of the support arm 22 and the connecting arm 21, and through the cooperation of the telescopic threaded rod 23 and the telescopic threaded sleeve 2, the telescopic threaded rod 23 and the telescopic threaded sleeve 2-2-3-3-4 ... The threaded connection between 4 provides movable support for the support clamping jaws 6-6. The telescopic threaded rod 23 rotates to push the telescopic threaded sleeve 24, which in turn pushes the support clamping jaws 6-6 to move, thus clamping the workpiece. The rotary drive motor 25 drives the spline sleeve 26 to rotate. The spline sleeve 26, through the positioning drive shaft 28, drives the positioning drive shaft 27 to rotate. The positioning drive shaft 27 then drives the positioning rotary seat 4-2 to rotate, which in turn rotates the pipe fitting. This, in turn, pushes the pipe cutting milling cutter module 3 forward via the feed telescopic unit 7. The pipe is cut by the pipe cutting milling cutter module 3. During the pipe rotation cutting process, the pipe drives the support rotating seat 6-5 to rotate, which in turn drives the support drive shaft 31 to drive, which in turn drives the output shaft of the overrunning clutch module 30 to rotate through the support drive shaft 32. The spline sleeve 26 drives the input shaft of the overrunning clutch module 30 to rotate through the spline shaft 29. The input shaft speed of the overrunning clutch module 30 is less than its output shaft speed. At this time, the overrunning clutch module 30 is in an open free rotation state, so that the spline shaft 29 does not transmit power to the support drive shaft 32.After the pipe fitting is cut, the positioning rotary seat 4-2 drives the workpiece clamped by the positioning clamping claw 4-4 to rotate. The rotary drive motor 25 inputs power to the overrunning clutch module 30 through the spline sleeve 26 and spline shaft 29. The overrunning clutch module 30 drives the support drive shaft 32 to rotate, which in turn drives the support drive shaft 31 to rotate and the support rotary seat 6-5 to rotate. The support rotary seat 6-5 then drives the pipe fitting clamped by the support clamping claw 6-6 to rotate, so that the pipe fittings on both sides rotate independently after cutting. The stepping hydraulic rod 6-3 pushes the stepping frame 6-2 to move to the right, and the stepping frame 6-2 drives the support mounting frame 6-4 to move to the right. This causes the pipe clamped by the support clamping claw 6-6 to move to the right, separating the cut sections on both sides of the pipe. Then, the pipe cutting milling module 3 moves backward and retracts. The lifting hydraulic rod 8-1 pushes the lifting stepping seat 8-2 downward, causing the grinding drive motor 8-3 to descend. This causes the wire brush disc 8-4 on the grinding drive motor 8-3 to press against the cut surfaces of the pipes on both sides. The grinding drive motor 8-3 drives the wire brush disc 8-4 to rotate, grinding the cut surfaces of the pipes. After grinding, the positioning clamping claw 4-4 and the support clamping claw 6-6 are opened, and the pipe is removed, completing the pipe cutting process.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. This solution uses a positioning rotating seat 4-2 to set a positioning clamping claw 4-4 and a supporting rotating seat 6-5 to set a supporting clamping claw 6-6. This allows the positioning clamping claw 4-4 and the supporting clamping claw 6-6 to work together to clamp and fix the pipe fitting. The positioning rotating seat 4-2 and the supporting rotating seat 6-5 work together to drive the pipe fitting to rotate, thereby enabling the pipe cutting milling cutter module 3 to cut the pipe fitting. After cutting, the lifting stepper seat 8-2 works with the grinding drive motor 8-3, and the steel wire brush 8-4 on the grinding drive motor 8-3 grinds and deburrs the cut end face of the pipe fitting. This achieves the multi-functional processing of cutting and grinding of the pipe cutting machine. 2. This device sets a stepping frame 6-2 on the frame 1, and then fixes the support mounting frame 6-4 on the stepping frame 6-2. The support mounting frame 6-4 sets a support rotating seat 6-5 and a support clamping claw 6-6. After the pipe is cut, the stepping frame 6-2 is moved to separate the two sides of the pipe, so as to grind the cut surface of the pipe. The rotation drive motor 25 drives the spline sleeve 26 to rotate, and then drives the positioning rotating seat 4-2 to rotate through the positioning transmission shaft 28 and the positioning drive shaft 27, thereby driving the pipe to rotate.
