Description

Technical Field

[0001] This invention belongs to the field of shaft and tube manufacturing technology, and specifically relates to an automatic flaring machine for shaft and tube manufacturing. Background Technology

[0002] A shaft tube is a cylindrical part widely used in mechanical equipment and an important component in the manufacturing process. Shaft tubes play a crucial supporting and connecting role in mechanical equipment, and their processing mainly involves multiple steps such as forming, cutting, and flaring. Flaring is a particularly important step in the production process, primarily to increase the diameter of the openings at both ends of the shaft tube to accommodate fittings of different sizes or to change the functional application of the shaft tube.

[0003] Existing traditional automatic flaring equipment for shafts and tubes has low functional integration and lacks a tube preheating unit. When metal shafts and tubes are directly flared at room temperature, their plasticity is poor, and the tube ends are prone to cracks and chipping defects when squeezed. In addition, the whole machine lacks a matching online grinding mechanism, and burrs are easily left on the edge of the tube end after flaring. An additional post-grinding process is required, making the processing flow lengthy and making it difficult to guarantee the quality of the formed workpiece and the continuous operation efficiency of the production line. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides an automatic flaring machine for shaft tube production and processing, which integrates tube end preheating, automatic grinding after flaring, crack prevention and deburring, and processing into one.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic flaring machine for shaft tube production and processing, comprising a base plate, a vertical plate slidably mounted on one side of the top surface of the base plate, a rotary seat installed at the end of the vertical plate, a processing box fixedly disposed on the other side of the top surface of the base plate, a feed port being opened on the side wall of the processing box corresponding to the position of the rotary seat, a clamping assembly for locking and fixing the shaft tube workpiece being provided inside the rotary seat, and a processing assembly capable of realizing integrated operation of tube preheating and flaring forming inside the processing box; The processing assembly includes a second motor. The second motor is fixedly installed on the base plate at a position corresponding to the vertical plate. The output shaft of the second motor is connected to a screw. A movable seat is threaded onto the outer wall of the screw. The movable seat is fixedly connected to the vertical plate. A partition is fixed in the middle of the inner cavity of the processing box. The partition divides the box into a heating chamber and an expansion chamber. An expansion cone is fixedly assembled in the expansion chamber at a position corresponding to the feed inlet. Heating wires are arranged inside the heating chamber. A controller for adjusting heating parameters is assembled on the lower side wall of the processing box.

[0006] Furthermore, the clamping assembly includes a strip groove formed inside the rotary seat, a bidirectional lead screw rotatably mounted inside the strip groove, sliding plates threaded to both sides of the bidirectional lead screw body, a clamping plate fixed to the outside of each sliding plate, and a moving groove formed inside the rotary seat that slides with the clamping plate.

[0007] Furthermore, the front wall of the processing box is fitted with transparent observation windows corresponding to the heating chamber and the expansion cavity, and a through-hole is opened in the center of the partition to allow the shaft tube workpiece to pass through.

[0008] Furthermore, the feed inlet is coaxially arranged with the rotary table, and the rotary table has a slot for receiving the end of the shaft tube on the side facing the feed inlet.

[0009] Furthermore, the two sliding plates and the double-acting screw have opposite thread directions. One end of the double-acting screw extends to the outside of the rotating seat and fixes the adjustment knob. Anti-slip buffer pads are attached to the opposite sides of each clamping plate.

[0010] Furthermore, the cavity is equipped with a cleaning component that can automatically remove burrs from the cavity. The cleaning assembly includes an electric push rod. The electric push rod is vertically installed on the top surface of the processing box corresponding to the position of the enlarged oral cavity. The output end of the electric push rod is fixed to the top plate. A fixing rod is vertically fixed on the top surface of the processing box. The fixing rod is slidably fitted with the top plate. An arc-shaped plate is assembled below the top plate. A steel wire brush is installed at the bottom end of the arc-shaped plate. A motor is fixed on the outside of the vertical plate. The output shaft of the motor is connected to the rotary seat transmission.

[0011] Furthermore, the cleaning assembly also includes a connecting column, with the connecting column vertically fixed to the bottom surface of the top plate, a connecting cylinder fixed to the lower end of the connecting column, a sliding seat slidably assembled inside the connecting cylinder, a buffer spring provided between the top surface of the sliding seat and the top end of the connecting cylinder, and the bottom end of the sliding seat connected to the arc plate through a sliding column.

[0012] Furthermore, the cleaning assembly also includes a waste collection box, a horizontally inserted receiving box at the bottom of the enlarged oral cavity, and a threaded locking bolt on the side wall of the processing box, with the end of the locking bolt pressing against the collection box to achieve limiting and fixing.

[0013] Furthermore, a guide sliding hole is provided on the top plate to fit the gap with the fixed rod, and an avoidance sliding hole is provided on the top surface of the machining box to allow the connecting cylinder to pass through vertically.

[0014] Furthermore, the front wall of the processing box has a pull-out slot that matches the shape of the collection box. After the collection box is fully pushed into the expansion cavity, the side of the box fits tightly against the inner wall of the expansion cavity.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a clamping assembly, uses a knob to drive a bidirectional lead screw to rotate, which drives two sets of sliding plates and clamping plates to move towards each other. It can quickly adapt to clamping and fixing the ends of metal shafts and tubes of different diameters. With the anti-slip pad of the clamping plate, the clamping friction is improved, the clamping stability is strong, and it can adapt to multiple working conditions such as processing feed and rotary grinding. It effectively prevents the shaft and tube from loosening, shifting, or falling during the processing, and improves the overall processing stability.

[0016] 2. This invention sets up processing components, uses a partition to separate the heating chamber and the flaring chamber, relies on the controller to regulate the heating wire to preheat and soften the flaring end of the shaft tube, and then uses a motor to push the shaft tube to fit the flaring cone to complete the flaring. This achieves integrated processing of preheating and flaring, optimizes the plasticity of the metal tube wall, and avoids the problems of shaft tube cracking and tube end breakage under stress at room temperature flaring from the root, effectively improving the qualified rate of shaft tube flaring.

[0017] 3. This invention, by setting up a cleaning component and a collection box, relies on a spring to make the steel wire brush elastically fit against the outer wall of the shaft tube. With the help of a motor, the shaft tube rotates, and the burrs at the flared end are removed by flexible grinding, avoiding the scratches on the tube wall caused by rigid grinding. At the same time, the plug-in collection box can collect the processing waste in a centralized manner, making disassembly and cleaning convenient, reducing the downtime of equipment for cleaning, and taking into account both the grinding quality of the workpiece and the continuity of equipment processing.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-5An automatic flaring machine for shaft and tube production includes a base plate 1, which serves as the support for the entire machine and provides installation support for various processing and transmission components, ensuring stable operation of the equipment. A vertical plate 6 is slidably mounted on one side of the top surface of the base plate 1. The vertical plate 6 can slide horizontally to feed and push the tube. A rotating seat 5 is installed at the end of the vertical plate 6, which carries the tube and can drive the tube to rotate. A processing box 2 is fixedly installed on the other side of the top surface of the base plate 1, providing a sealed processing space for tube preheating, flaring, and deburring. A feed port 4 is opened on the side wall of the processing box 2 corresponding to the position of the rotating seat 5, allowing the shaft and tube workpiece to be smoothly inserted into the box for processing. A clamping component 9 is provided inside the rotating seat 5 to lock and fix the shaft and tube workpiece to prevent it from loosening during processing. A processing component 8 is assembled inside the processing box 2, which can simultaneously complete the integrated processing operation of tube preheating and flaring.

[0021] Please see Figure 1-3 The processing component 8 includes a second motor 87. The second motor 87 is fixedly installed on the base plate 1 at a position corresponding to the vertical plate 6. The second motor 87 provides power for the pipe feed. The output shaft of the second motor 87 is connected to a screw 88. The rotation of the screw 88 achieves threaded feed transmission. A movable seat 89 is threaded onto the outer wall of the screw 88. The movable seat 89 moves horizontally and linearly with the rotation of the screw 88. The movable seat 89 is fixedly connected to the vertical plate 6, and can synchronously drive the vertical plate 6 and the pipe to feed as a whole. A partition is fixed in the middle of the inner cavity of the processing box 2. Plate 83 divides the box into heating chamber 85 and flaring chamber 86, completing the heating and flaring processes in separate sections. Flaring cone 84 is fixedly installed in the flaring chamber 86 at the position corresponding to the feed port 4, which extrudes and softens the tube wall to complete the flaring and shaping. Heating wire 82 is arranged inside the heating chamber 85. When energized, it heats and softens the tube opening. Controller 81 is installed on the lower side wall of the processing box 2. Controller 81 precisely controls the heating power, temperature and duration of heating wire 82 to adapt to the processing requirements of different tube diameters.

[0022] Please see Figure 5 The clamping assembly 9 includes a strip groove 92 inside the rotary base 5. The strip groove 92 provides space for the internal transmission components to move. A bidirectional lead screw 91 is rotatably installed inside the strip groove 92. The rotation of the bidirectional lead screw 91 can drive the components on both sides to move in opposite directions. The two sides of the bidirectional lead screw 91 are respectively threaded to the sliding plates 93, so that the two sets of sliding plates 93 can move towards each other and away from each other. A clamping plate 94 is fixed on the outside of each sliding plate 93. The clamping plate 94 directly fits against the outer wall of the shaft tube. A moving groove 95 is opened inside the rotary base 5 to slide and cooperate with the clamping plate 94, limiting the movement trajectory of the clamping plate 94, so that the clamping is stable and without deviation.

[0023] Please see Figure 1-3 Transparent observation windows are installed on the front wall of the processing box 2, corresponding to the heating chamber 85 and the flaring chamber 86, respectively, so that the operator can observe the internal heating and flaring processing status in real time. A through opening is opened in the center of the partition 83 so that the shaft tube workpiece can pass through, which facilitates the shaft tube to move and feed between the two cavities.

[0024] Please see Figure 1-3 The feed port 4 and the rotary seat 5 are arranged coaxially to ensure that the shaft tube is shifted and fed without deviation, and the machining concentricity is high. The rotary seat 5 has a slot 10 on the side facing the feed port 4, which can directly insert and position the end of the shaft tube, making it convenient for the pre-assembly and alignment of the fittings.

[0025] Please see Figure 5 The two sliding plates 93 and the double-acting screw 91 have opposite thread directions. The two sets of clamping plates 94 can be clamped and released synchronously by rotating the double-acting screw 91 in one direction. One end of the double-acting screw 91 extends to the outside of the rotating base 5 and fixes the adjustment knob. The clamping can be manually operated without tools. Anti-slip buffer pads are attached to the opposite sides of each clamping plate 94 to increase the clamping friction of the pipe and at the same time avoid clamping and squeezing to scratch the outer wall of the shaft tube.

[0026] Please see Figure 1-5 The flared mouthpiece 86 is equipped with a cleaning component 3, which can automatically grind and remove burrs from the tube opening after flaring, eliminating the need for manual post-processing. The cleaning component 3 includes an electric push rod 31, which is vertically installed on the top surface of the processing box 2 corresponding to the position of the flared mouthpiece 86, providing vertical lifting power for the brush. The output end of the electric push rod 31 is fixed to the top plate 32, driving the top plate 32 to rise and fall vertically. The top surface of the processing box 2 is vertically fixed with a fixing rod 35, which slides with the top plate 32 to provide vertical guidance. An arc plate 37 is installed below the top plate 32 to fit and conform to the outer wall of the circular shaft tube. A steel wire brush 38 is installed at the bottom of the arc plate 37 to directly rub and grind the burrs at the tube opening. A motor 7 is fixed on the outside of the upright plate 6. The output shaft of the motor 7 is connected to the rotating base 5 for transmission, driving the tube to rotate and grind autonomously.

[0027] Please see Figure 4 The cleaning component 3 also includes a connecting column 33. The connecting column 33 is vertically fixed on the bottom surface of the top plate 32 to transmit downward pressure. The lower end of the connecting column 33 is fixed to the connecting cylinder 34, which is a buffer component bearing shell. The inner cavity of the connecting cylinder 34 is slidably fitted with a slide block 39, which can slide vertically along the inside of the cylinder. A buffer spring 310 is set between the top surface of the slide block 39 and the top of the connecting cylinder 34 to provide elastic clamping force. The bottom end of the slide block 39 is connected to the arc plate 37 through the sliding column 36 to realize the elastic contact of the brush with the pipe.

[0028] Please see Figure 1-3 The cleaning component 3 also includes a waste collection box 311. The collection box 311 is horizontally inserted into the bottom of the inner cavity of the expanded oral cavity 86 to collect the metal burrs and waste chips that have been ground off. The side wall of the processing box 2 is threaded with locking bolts 312. The end of the locking bolts 312 is pressed against the collection box 311 to achieve limit fixation and prevent the box from slipping and leaking during operation.

[0029] Please see Figure 1-3The top plate 32 has a guide hole that fits with the fixed rod 35, so that the lifting and sliding are smooth and without jamming. The top surface of the processing box 2 has an avoidance hole that allows the connecting cylinder 34 to pass through vertically, so as to avoid structural interference and ensure the normal lifting and lowering operation of the brush.

[0030] Please see Figure 1-3 The front wall of the processing box 2 has a pull-out slot 10 that matches the shape of the collection box 311, making it easy to disassemble and assemble. After the collection box 311 is fully pushed into the expansion cavity 86, the side of the box fits tightly against the inner wall of the expansion cavity 86, preventing the leakage and accumulation of waste debris.

[0031] The working principle and usage process of this invention: When using the automatic flaring machine for shaft tube production and processing, the device is installed in a suitable position, and the end of the metal shaft tube to be flared is horizontally inserted into the slot 10 opened on one side of the rotating base 5. The operator rotates the adjustment knob, and the knob synchronously drives the bidirectional lead screw 91 to rotate and transmit within the strip groove 92 of the vertical plate 6. During the rotation of the bidirectional lead screw 91, it drives the upper and lower sets of sliding plates 93 to move towards each other synchronously. The sliding plates 93 synchronously drive the clamping plate 94 to move linearly along the corresponding moving groove 95. The two clamping plates 94 cooperate with each other to clamp the end of the shaft tube. The entire set of clamping components 9 achieves stable clamping and positioning of the end of the shaft tube to be processed, effectively preventing the shaft tube from loosening or falling off during the equipment processing.

[0032] The second motor 87 drives the screw 88 to rotate. The screw 88 drives the moving seat 89 to move smoothly along the guide rail of the base plate 1. The moving seat 89 synchronously drives the vertical plate 6 and the clamped and fixed shaft tube to feed synchronously. The shaft tube extends into the heating chamber 85 on one side of the box through the feed port 4 on the side wall of the processing box 2. The equipment controller 81 precisely controls the heating wire 82 to heat up, uniformly preheating and softening the end of the shaft tube to be flared. After the tube end heating process is completed, the second motor 87 drives the vertical plate 6 to push the shaft tube forward again. The heated end of the shaft tube passes through the partition 83 and enters the flaring cavity 86. The end face of the shaft tube fits against the flaring cone 84. As the shaft tube continues to feed, the flaring cone 84 squeezes the tube wall to complete the flaring. The processing component 8 integrates the tube end preheating and flaring forming functions to avoid forming defects such as tube end cracks and tube wall breakage caused by direct flaring at room temperature.

[0033] After the flaring process is completed, the motor 87 reverses and drives the screw 88 to rotate, causing the shaft tube to retract and completely separate from the flared conical body 84. Then, the electric push rod 31 is activated to retract, and the electric push rod 31 pulls the top plate 32 to slide vertically downward. The fixing rod 35 passes through the top plate 32 and plays a vertical guiding and limiting role. The downward movement of the top plate 32 pushes the lower arc plate 37, so that the steel wire brush 38 assembled at the bottom of the arc plate 37 adheres to and presses against the outer wall of the shaft tube. The sliding column 36 connected to the top of the arc plate 37 slides along the inside of the connecting cylinder 34 and compresses the buffer spring 310 as the top plate 32 is pressed down. With the help of the elastic buffer structure of the buffer spring 310, the wire brush 38 can always elastically press against the outer wall of the shaft tube, while avoiding the rigid hard contact between the brush and the pipe and scratching the pipe wall. At this time, the motor 7 is started to drive the rotating seat 5 to rotate as a whole. The rotating seat 5 drives the shaft tube that is clamped and fixed to rotate synchronously. During the rotation, the wire brush 38 continuously rubs and polishes the flared end of the shaft tube, automatically removing the burrs generated by the flaring process. The entire cleaning assembly 3 at the top realizes the fully automatic polishing and deburring of the pipe end after flaring.

[0034] The bottom of the processing box 2 has a reserved installation position below the flared cavity 86. The collection box 311 is inserted into the bottom of the cavity in a horizontal direction. The locking bolt 312 is tightened to lock and position the collection box 311. When the equipment performs pipe flaring and brush grinding operations, the metal waste and burrs generated during processing fall into the collection box 311 by their own weight and are collected. The collection box 311 adopts a drawer-type plug-in assembly structure. The box can be pulled out by loosening the locking bolt 312, which makes it easy for operators to quickly clean the accumulated metal waste inside and reduce the downtime for equipment maintenance.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
