Description

TECHNICAL FIELD

[0001] The application relates to the technical field of steel pipe processing, and particularly relates to an intelligent cutting machine bed for steel pipe production. BACKGROUND

[0002] Steel pipe is a long strip steel material with a hollow section, which can be divided into various types according to production processes, section shapes, materials and purposes, and common types are round pipes and square pipes. Square pipes are usually used to build building structures such as steel structure beams, columns and high-rise building frames, or mechanical frames such as industrial equipment supports and agricultural machinery frames. Square pipes need to be cut in actual application, and the main reason is that the original length of the square pipes cannot directly meet the needs of specific projects or products.

[0003] The prior art such as Chinese patent CN109663968B provides a cutting device for steel pipe production and manufacturing, which comprises a base, a support arranged on the base, a damping device arranged at the bottom of the base for absorbing vibration when cutting the steel pipe, a main lifting mechanism arranged on the support and a moving block connected with the main lifting mechanism, a pair of steel pipe pressing mechanisms connected with the moving block, a balancing device arranged on the moving block for keeping the pressure of the pair of steel pipe pressing mechanisms balanced, a cutting lifting mechanism connected with the moving block and a steel pipe cutting device connected with the cutting lifting mechanism. The cutting device can balance the clamping force acting on the steel pipe by arranging symmetrical connecting pipes and oil-filled cavities connected with the connecting pipes, so that the cutting device will not have a broken section at the cutting position when cutting the steel pipe. The bottom damping device can reduce the vibration during cutting, and the cutting is more stable.

[0004] In the scheme, the two ends of the steel pipe are pressed by the steel pipe pressing mechanism to ensure the stability of the steel pipe during cutting and to ensure the cutting quality. However, during actual operation, the steel pipe needs to be placed at a specified position before being fixed. Since the equipment itself lacks a positioning mechanism, the steel pipe needs to be positioned manually every time, and the efficiency of manual operation is inevitably affected by the proficiency of workers. In addition, inaccurate positioning can cause the cutting slope of the steel pipe to be inclined, affecting the cutting quality.

[0005] The prior art such as Chinese patent "CN118492490A" provides a cutting equipment for steel pipe production and processing, which comprises a main shell, a conveying belt groove is formed above the main shell, a servo motor is arranged inside the main shell, and a conveying track is arranged on the inner side of the conveying belt groove. In the present application, the fixing of steel pipes of different sizes can be quickly completed through the design of the first arc-shaped plate and the second arc-shaped plate, the operation process is simplified, the time required for fixing the steel pipe is reduced, the steel pipe and the cutting knife are cooled and cleaned during the cutting process through the design of the atomizing cooling nozzle and the water pump, the damage and deformation caused by high temperature are reduced, the cutting quality is improved, the recycling of water resources is realized through the design of the punching water discharge plate and the water storage tank, and the operating cost is reduced. Through the structure of the limiting sliding groove and the first sliding block, the overall and internal components of the steel pipe fixing mechanism are mostly detachable, which facilitates maintenance and replacement of parts, and reduces maintenance cost.

[0006] In the scheme, the steel pipe fixing mechanism for fixing multiple sets of steel pipes is arranged on the conveying track, so that the cutting mechanism can continuously work when batch processing is performed, and the processing efficiency is improved. However, in practice, the steel pipe fixing mechanism requires that each time a steel pipe is placed, the plug-in handle is pulled outward, the second arc-shaped plate is pushed to make the first soft pad and the second soft pad tightly adhere to the steel pipe, the plug-in handle is loosened, and the fixing plug is clamped into the corresponding clamping groove, so that the fixing of steel pipes of different sizes can be quickly and conveniently completed in a self-adaptive manner. Although this design simplifies the operation process and reduces the time required for fixing the steel pipe, manual assistance is still required for operation, which results in a large workload for manual operation when a large number of steel pipes are processed, and the length of the processable steel pipe is limited by the conveying range of the conveying track, so that some long steel pipes cannot be processed. SUMMARY

[0007] The present application aims to solve the above problems and provides an intelligent cutting machine tool for steel pipe production, which overcomes the defects of the prior art, as described in detail below.

[0015] As preferred, one end of the conveying mechanism is provided with a discharging mechanism, the discharging mechanism comprises a second support base, the second support base is fixedly connected with one of the first support bases, a discharging table is arranged above the second support base, a first support column is fixedly connected to the top of the second support base, and the rotating shaft of the discharging table is rotatably connected to the top of the first support column, a torsional spring for resetting is arranged at the connection between the rotating shaft of the discharging table and the first support column, and a plurality of second rolling balls are rolling connected to the top of the discharging table.

[0016] As preferred, the top of the second support base is fixedly connected with a second support column, the second support column is slidingly connected with a slide rod at a position above the discharging table, a trigger plate is slidingly connected with the outer wall of the slide rod through a sliding sleeve, the trigger plate is located above the discharging table, a locking nut is arranged at the position of the sliding sleeve, and the two ends of the slide rod are respectively fixedly connected with connecting rods, a limiting assembly is arranged at the bottom of the connecting rod, the limiting assembly comprises a first end face gear, the first end face gear is fixedly connected to the bottom of the connecting rod, and the first end face gear is slidingly sleeved at one end of the rotating shaft of the discharging table, the outer wall of the rotating shaft of the discharging table is fixedly sleeved with a second end face gear matched with the first end face gear, the outer wall of the rotating shaft of the discharging table is fixedly sleeved with a support ring, and a spring is fixedly connected between the support ring and the first end face gear.

[0017] As preferred, one side of the second support base is fixedly connected with a sliding table, the top of the sliding table is fixedly connected with a guide roller, one side of the sliding table close to the discharging table is fixedly connected with a limiting strip, and one side of the bottom of the sliding table is fixedly connected with a baffle.

[0018] The beneficial effects are that: Firstly, the second bevel gear on the outer wall of the rotating rod is rotated by the servo motor, and the positioning roller and the plurality of conveying rollers are synchronously rotated through the meshing first bevel gear, so that the long square steel pipes are conveniently conveyed and fed, the manual feeding is saved, the efficiency is improved, the limiting ring movably arranged on both sides of the positioning roller is used to conveniently limit the square steel pipes with different widths, the square steel pipes are prevented from deviating during the conveying process, and the problem that the cutting section is inclined due to improper placement during the cutting of the square steel pipes, thereby affecting the cutting quality of the square steel pipes, is avoided.

[0019] Secondly, the pressing roller can apply a downward pressure on the square steel pipes during the conveying of the square steel pipes, so that the square steel pipes are more stable during the conveying process and are not shaken or inclined, the square steel pipes are not easily displaced during the cutting, the cutting quality is ensured, and the position of the square steel pipes can be kept stable during the cutting of part of the material of the square steel pipes due to the action of the pressing roller, the square steel pipes are not out of balance and tilted due to the change of the center of gravity, and the subsequent cutting or conveying is not affected.

[0020] Third, the spring is arranged in the pressure pipe to support the first sealing plug against the inner wall of the pressure pipe, so that the hydraulic pump has a sequence when injecting hydraulic oil into the annular cavity and the telescopic rod. The tension of the spring pushes the first sealing plug against the top of the pressure pipe, blocks the pressure pipe, and makes the hydraulic oil preferentially injected into the annular cavity when the hydraulic pump is pressurized, so that the annular piston extends to drive the limiting ring to push the square steel pipe to be corrected. When the limiting ring pushes the square steel pipe to be completely parallel to the contact surface of the limiting ring, the square steel pipe is in a right state, the limiting ring cannot move, and the pressure pipe is under pressure. When the pressure pushing the first sealing plug overcomes the tension of the spring, the hydraulic oil pushes the first sealing plug to inject into the telescopic rod, so that the telescopic rod extends to drive the pressure roller to press down and fix, thereby avoiding the problem that the limiting ring on both sides extends to correct the square steel pipe.

[0021] Fourth, the linkage assembly is arranged, so that the limiting ring moves to drive the rack below the connecting ring to move. Since the two limiting rings are connected with the racks on both sides, the racks mesh with the same linkage gear, so that the two limiting rings are in a synchronous symmetrical motion state when moving on the positioning roller. Therefore, the two limiting rings are always at the center position of the positioning roller when pushing the square steel pipe to be positioned, that is, exactly at the center position of the cutting area of the saw belt driving device, so as to avoid uneven stress of the saw belt during cutting, and to avoid local wear and tear of the device after a long time, thereby affecting the service life of the equipment.

[0022] Fifth, when the square steel pipe is conveyed to above the discharging table, one end of the square steel pipe pushes the trigger plate, so that the slide rod connected with the trigger plate is displaced, thereby driving the first end face ratchet below the connecting rod at both ends of the slide rod to move, so that the first end face ratchet is separated from the second end face ratchet, and the rotation of the trigger plate is limited. At this time, the weight of the square steel pipe above the discharging table overcomes the torsional spring elastic force at the rotating shaft of the trigger plate, so that the discharging table rotates to be inclined, and the square steel pipe slides along the inclined surface of the discharging table to fall onto the slide table, and then slides along the inclined surface of the slide table to the flat area of the slide table for placement. When the square steel pipe slides out of the discharging table, the slide table is automatically reset under the action of the torsional spring elastic force. When the trigger plate is separated from the square steel pipe, the tension of the spring between the supporting ring and the first end face ratchet pushes the first end face ratchet to re-engage the second end face ratchet, thereby limiting the downward rotation direction of the discharging table, so as to facilitate the subsequent square steel pipe to be continuously conveyed to above the discharging table, thereby realizing continuous automatic discharging, reducing the labor input, and improving the processing efficiency. The position of the sliding sleeve on the trigger plate on the slide rod can be adjusted by the loose locking nut, so as to facilitate the adjustment according to different cutting lengths, thereby adapting to the discharging of square steel pipes with different cutting lengths.

DETAILED DESCRIPTION

[0027] Reference is made to Figures 1-11As shown, the present application provides an intelligent cutting machine for steel pipe production, including base 1, the top of base 1 is provided with saw belt driving device 3, the top of base 1 is connected with lifting platform 2 for driving saw belt driving device 3 lifting, both ends of base 1 are provided with conveying mechanism respectively, for conveying steel pipe, conveying mechanism includes first support base 4, first support base 4 is fixedly connected with one end of base 1, first support base 4 is provided with support frame 6 at the position close to saw belt driving device 3, the inner wall of support frame 6 is rotatably connected with positioning roller 7, the outer portion of positioning roller 7 is provided with limiting assembly, the top of support frame 6 is provided with pressing assembly, limiting assembly includes two sets of limiting ring 8, limiting ring 8 is movably sleeved on both sides of the outer wall of positioning roller 7, the inner wall of support frame 6 is respectively provided with annular cavity 81 at the position corresponding to two sets of limiting ring 8, the inner wall of two annular cavities 81 is slidably connected with annular piston 82, for pushing limiting ring 8 to move on the outer wall of positioning roller 7, by the way of setting limiting ring 8 on both sides of the outer wall of positioning roller 7, when conveying mechanism conveys the cutting position of square steel pipe below saw belt driving device 3, hydraulic oil can be injected into the annular cavities 81 on the two support frames 6, annular piston 82 is pushed out, limiting ring 8 is pushed by the extended annular piston 82, and the two sides of the cutting position of square steel pipe on both ends are clamped and corrected, so that the problem that the cutting section is inclined and the quality of steel pipe cutting is affected due to improper placement when cutting square steel pipe is avoided, a plurality of first balls 85 are rollingly connected to the side of limiting ring 8 in contact with square steel pipe, by the way of rollingly contacting first balls 85 on the side of limiting ring 8 in contact with square steel pipe, the friction force of the contact surface of limiting ring 8 and square steel pipe is avoided to avoid excessive wear of limiting ring 8.

[0028] In this embodiment, please refer to Figure 3 、 Figure 6 , the pressing assembly includes telescopic rod 91, the telescopic rod 91 is vertically connected to the top of support frame 6, the bottom of telescopic rod 91 is rotatably connected with two sets of pressing rollers 9 through connecting frame, by the way of setting pressing assembly, when conveying square steel pipe, hydraulic oil can be injected into telescopic rod 91 to make telescopic rod 91 stretch, so as to conveniently drive two sets of pressing rollers 9 to press down and press the top of steel pipe, avoid affecting the position of barycenter due to the change of mass distribution caused by the cutting of part of material of square steel pipe in the conveying process, which may cause the square steel pipe to lose balance and tilt up, affecting subsequent cutting or transportation.

[0029] Further, please refer to Figure 4 、 Figure 6Two sides of the support frame 6 are respectively provided with pipelines 83, a hydraulic pump is arranged in the first support base 4, and the hydraulic pump is connected with the two pipelines 83 through a three-way joint, one end of the two pipelines 83 away from the hydraulic pump is connected with the telescopic rod 91 through a three-way joint, the middle positions of the two pipelines 83 are communicated with the corresponding annular cavities 81 through branch pipes, and the position of the three-way joint at the telescopic rod 91 is provided with a pressure pipe 92, the hydraulic oil is injected into the corresponding annular cavities 81 and the telescopic rod 91 through the pipelines 83 by the hydraulic pump, so that the compression roller 9 and the limiting ring 8 can be conveniently driven to be telescopic and close to the square steel pipe for positioning and fixing, and the square steel pipes of different models can be fixed.

[0030] Further, please refer to Figure 4 、 Figure 6 、 Figure 7 The inner wall of the pressure pipe 92 is slidably connected with a first sealing plug 93, and the position between the inner wall of the pressure pipe 92 and the bottom of the first sealing plug 93 is fixedly connected with a spring, and the top of the first sealing plug 93 abuts against the inner wall of the pressure pipe 92. By arranging the spring in the pressure pipe 92 to support the first sealing plug 93 against the inner wall of the pressure pipe 92, the hydraulic oil can be injected into the annular cavity 81 and the telescopic rod 91 in sequence when the hydraulic pump is pressurized. Because the tension of the spring pushes the first sealing plug 93 against the top of the pressure pipe 92, the pressure pipe 92 is blocked, so that the hydraulic oil is preferentially injected into the annular cavity 81 when the hydraulic pump is pressurized, so that the annular piston 82 is extended to drive the limiting ring 8 to push the square steel pipe to be corrected. When the limiting ring 8 pushes the square steel pipe to be completely parallel to the contact surface of the limiting ring 8, the square steel pipe is in a right state, and the limiting ring 8 cannot continue to move, so that the pressure pipe 92 is under pressure. When the pressure pushing the first sealing plug 93 overcomes the tension of the spring, the hydraulic oil pushes the first sealing plug 93 to inject into the telescopic rod 91, so that the telescopic rod 91 is extended to drive the compression roller 9 to be pressed to be fixed, thereby avoiding the situation that the limiting ring 8 on both sides is not right when the square steel pipe is right. The telescopic rod 91 drives the compression roller 9 to press the top of the square steel pipe, and the downward pressure increases the friction between the square steel pipe and the positioning roller 7, so that the difficulty of correcting the square steel pipe by the limiting ring 8 is increased.

[0031] In addition, please refer to Figure 6 、 Figure 7 、 Figure 8The inner wall of the first sealing plug 93 is provided with a backflow channel 931, and the inside of the backflow channel 931 is provided with a second sealing plug 932. The top of the second sealing plug 932 is fixedly connected to the position between the inner wall of the backflow channel 931, and the bottom of the second sealing plug 932 abuts against the inner wall of the backflow channel 931. The spring is arranged in the backflow channel 931 of the first sealing plug 93 to support the second sealing plug 932 abutting against the bottom of the backflow channel 931. The spring can play the role of a one-way valve, and can ensure that the hydraulic oil does not affect the sealing of the first sealing plug 93 against the inner wall of the pressure pipe 92 when the hydraulic oil is ready to enter the pressure pipe 92. When the hydraulic oil flows back, the negative pressure generated by the hydraulic oil flow can overcome the tension of the spring, so that the second sealing plug 932 is separated from the inner wall of the backflow channel 931, and the hydraulic oil can drive the telescopic rod 91 to retract and drive the pressure roller 9 to lift up.

[0032] In addition, please refer to Figure 1 、 Figure 5 、 Figure 9 The linkage assembly is arranged between the two groups of limiting rings 8. The linkage assembly includes two groups of connecting rings 84. The two groups of connecting rings 84 are rotatably connected to the outer walls of the two groups of limiting rings 8. The bottoms of the two groups of connecting rings 84 are fixedly connected with two racks 842, respectively. The top of the first support seat 4 is rotatably connected with a linkage gear 841 between the two racks 842. The linkage gear 841 is in meshing connection with the two racks 842. The rack 842 is in sliding connection with the first support seat 4 through a sliding rail. The connecting ring 84 is fixedly connected with the annular piston 82 at the corresponding position. The linkage assembly is arranged to drive the connecting ring 84 below the rack 842 to move together when the limiting ring 8 moves. Since the two limiting rings 8 on the sides are connected with the racks 842, respectively, and are in meshing connection with the same linkage gear 841, the two limiting rings 8 are in a synchronous and symmetrical motion state when they move on the positioning roller 7. Therefore, the two limiting rings 8 are always located at the center position of the positioning roller 7 when they push the square steel pipe to be positioned, that is, they are exactly located at the center position of the cutting area of the saw belt driving device 3. This can avoid uneven stress on the saw belt during cutting, and can prevent the device from being locally worn out after a long time of use, thereby prolonging the service life of the equipment.

different cutting lengths, and the position of the sliding sleeve on the trigger plate 114 on the slide rod 112 can be adjusted through the loose locking nut 115, so that the length of the cutting can be adjusted, thereby adapting to the unloading of the square steel pipe with different cutting lengths.

[0035] Working principle In use, the square steel pipe to be cut is placed above the conveying rollers 5, the second bevel gear 54 on the outer wall of the rotating rod 53 is driven to rotate by starting the servo motor 52, and the positioning roller 7 is driven to rotate synchronously with the conveying rollers 5 through the meshing first bevel gear 51, so as to facilitate the conveying of the square steel pipe. When the square steel pipe is conveyed to the position of the supporting frame 6, the hydraulic oil is injected into the corresponding annular cavity 81 and the telescopic rod 91 through the pipeline 83 by the hydraulic pump, so as to facilitate the positioning and fixing of the pressing roller 9 and the limiting ring 8 close to the square steel pipe. By arranging the spring to support the first sealing plug 93 against the inner wall of the pressure pipe 92 in the pressure pipe 92, the hydraulic oil can be injected into the annular cavity 81 and the telescopic rod 91 in sequence. Since the tension of the spring pushes the first sealing plug 93 against the top of the pressure pipe 92, the pressure pipe 92 is blocked, so that the hydraulic oil is preferentially injected into the annular cavity 81 when the hydraulic pump is pressurized, so that the annular piston 82 extends to drive the limiting ring 8 to push the square steel pipe to correct it. When the limiting ring 8 pushes the square steel pipe to be in full parallel with the contact surface of the limiting ring 8, the square steel pipe is in the right position, and the limiting ring 8 moves to drive the rack 842 below the connecting ring 84 to move. Since the two limiting rings 8 are connected with the racks 842 on both sides, they mesh with the same linkage gear 841, so that the two limiting rings 8 are in a synchronous and symmetrical motion state when they move on the positioning roller 7. Therefore, the two limiting rings 8 are always in the center position of the positioning roller 7 when they push the square steel pipe to be positioned, that is, they are exactly in the center position of the cutting area of the saw belt driving device 3, so as to avoid uneven stress when the saw belt cuts. When the limiting ring 8 cannot continue to move, the pressure pipe 92 is under increased pressure, and the pressure pushing the first sealing plug 93 overcomes the tension of the spring, so that the hydraulic oil pushes the first sealing plug 93 to inject into the telescopic rod 91, so that the telescopic rod 91 extends to drive the pressing roller 9 to press down for fixing, thereby avoiding the situation that the two limiting rings 8 on both sides have not corrected the square steel pipe. When the square steel pipe is conveyed above the discharging table 11, one end of the square steel pipe pushes the trigger plate 114, so that the slide rod 112 connected with the trigger plate 114 is displaced, thereby driving the first end face gear 117 below the connecting rod 116 at both ends of the slide rod 112 to move, so that the first end face gear 117 is separated from the second end face gear 118, and the rotation of the trigger plate 114 is limited. At this time, the weight of the square steel pipe above the discharging table 11 overcomes the torsional spring force at the rotating shaft of the trigger plate 114, so that the discharging table 11 rotates and tilts, and the square steel pipe slides along the inclined surface of the discharging table 11. The square steel pipe falls onto the sliding table 12 and slides along the inclined surface of the sliding table 12 to the flat area of the sliding table 12 for placement. When the square steel pipe slides off the discharging table 11, the sliding table 12 is automatically reset under the action of the torsional spring force. When the trigger plate 114 is separated from the square steel pipe, the tension of the spring between the supporting ring 119 and the first end face gear 117 pushes the first end face gear 117 to reengage the second end face gear 118, thereby limiting the downward rotation of the discharging table 11.Convenient for the subsequent square steel pipe to continue to be sent to the blanking table 11, so as to realize continuous automatic blanking, and the position of the sliding sleeve on the trigger plate 114 on the slide rod 112 can be adjusted through the loose locking nut 115, so as to facilitate the adjustment according to different cutting lengths, so as to adapt to the blanking of square steel pipes with different cutting lengths.
