Description

Technical Field

[0001] This invention relates to the field of shearing machine technology, specifically to a hydraulic swing beam shearing machine for processing metal honeycomb carriers that can automatically feed materials. Background Technology

[0002] Metal honeycomb carriers, as key structural components used in automotive exhaust purification and industrial catalysis, are typically made from millimeter-thick metal foil through processes such as winding and welding to form a honeycomb structure. In the preceding processing steps, large rolls of metal foil need to be precisely slit into strips or sheets of specific widths. The precision and efficiency of this slitting process directly affect the geometric consistency of the honeycomb carrier and the final product performance. Hydraulic swing beam shearing machines are commonly used in metal sheet shearing due to their high shearing force, good cut quality, and strong adaptability.

[0003] However, the foil used in metal honeycomb carriers is thin and relatively soft, making it prone to wrinkles and scratches during transport due to uneven friction and unstable traction. Traditional shearing machines, which rely on rollers or manual pushing for feeding, cannot guarantee the flatness of the foil, severely affecting the shearing quality and material utilization. Secondly, the foil is prone to deviation during long-distance transport, and traditional equipment lacks an online, real-time, precise deviation correction mechanism, usually relying on manual observation and adjustment. This is not only inefficient and labor-intensive, but also difficult to guarantee accuracy, resulting in large errors in the width of the sheared strips, which cannot meet the high consistency assembly requirements of honeycomb carriers. Summary of the Invention

[0004] The purpose of this invention is to provide a hydraulic swing beam shearing machine for processing metal honeycomb carriers with automatic feeding, so as to improve the shearing quality of metal foil materials for honeycomb carrier processing and solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic swing beam shearing machine for processing metal honeycomb carriers with automatic feeding, comprising a machine base and a shearing seat in the middle, and an automatic feeding system provided on the feeding side of the machine base; the system includes a feeding roller for holding the roll; a conveyor belt located downstream of the feeding roller and driven by a drive roller, the conveyor belt being installed between two side plates and having through-hole micro-perforations, and a vacuum chamber connected to a negative pressure source through a main pipe below it, so as to generate an adsorption force on the surface of the conveyor belt; A skew detection mechanism is provided on the connecting plate between the conveyor belt and the shear seat. The mechanism includes a limiting seat symmetrically installed on both sides, a guide column movably installed in the movable groove of the limiting seat, and a pressure sensor located between the guide column and the limiting seat. A correction mechanism is provided above the conveyor belt for real-time correction of the conveying end of the foil. It includes a horizontally installed first track, a correction head driven by the first track, and a ball bearing that is rotatably installed at the bottom of the correction head via a spherical pair. The correction head is equipped with a pneumatic switchable clamping assembly for the ball bearing and is connected to the main pipe through an air extraction pipe and a secondary pipe. A push-type drum self-aligning mechanism is provided below the open end of the feeding roller to correct the conveying deviation of the foil material from the feeding source.

[0006] The conveyor belt is a ring belt wound around two drive rollers, one of which is driven by a geared motor. The vacuum chamber is fixedly installed between the two side plates, with its evacuation surface facing upwards and connected to the main pipeline through an air box embedded in the side plate.

[0007] The connecting plate is fixedly installed on the shear seat. Its bottom surface is an arc-shaped surface that fits against the side of the conveyor belt, and its upper surface is flush with the upper surface of the conveyor belt and the upper surface of the shear seat. It is used to smoothly guide the foil from the conveyor belt to the shear seat.

[0008] In the skew detection mechanism, each limiting seat has at least three movable slots arranged along the moving direction of the foil, and each movable slot is equipped with a guide column that is limited, slidable and rotatable by a hanging shaft; Pressure sensors are positioned behind each guide post to detect the pressure exerted by the foil edge on the guide post and convert it into an electrical signal.

[0009] The correction mechanism also includes a bracket horizontally installed between two side plates, and the first track is fixedly installed in the middle of the bracket by bolts; The correction head can move laterally along the first track, perpendicular to the direction of foil movement.

[0010] The pneumatic switchable clamping assembly includes two sets of spring guide rods symmetrically arranged on the upper part of the correction head, two semi-circular slides movably installed on both sides of the correction head via the spring guide rods, a chuck integrally formed on the bottom of the semi-circular slides, a rotating shaft rotatably installed on the top of the correction head via a rotating groove, a fan blade fixed on the rotating shaft, and two hanging balls symmetrically connected to the bottom of the rotating shaft. The exhaust pipe is connected to the correction head near the fan blades, and a solenoid valve is installed on the secondary pipe.

[0011] The push-type drum self-aligning mechanism includes a slide rail fixed to the ground by expansion bolts and a vertical slide block that is limited and slidably mounted on the slide rail; A second track is horizontally mounted on the top of the slide block by screws, and its direction is consistent with the axis of the feed roller. The second track is equipped with a pressure plate with a sleeve hole, which can be sleeved on the feeding roller and driven by the second track to move along its axial direction.

[0012] Both ends of the slide rail are equipped with a foot-operated unlocking locking structure to fix the slide block at a position close to or away from the feeding roller. The locking structure includes a base fixed to the side of the slide rail, a spring pin that can pop up in the base, and a foot pedal welded to the spring pin. The spring pin can be engaged with the socket at the bottom of the slide to achieve locking.

[0013] Among them, the feeding roller is installed on the front support, and an elastic element is sleeved on one end near the front support. A limit plate is also movably sleeved on the feeding roller. The limiting plate is fixedly connected to the elastic element and is used to support and limit one side of the drum, and to use the elastic force to squeeze the drum to the other side.

[0014] It also includes a control system, which is electrically connected to each pressure sensor, the first rail, the second rail, and the solenoid valves on the auxiliary pipeline. When the pressure sensor detects foil skew, the control system stops the negative pressure source, brakes the conveyor belt and closes the solenoid valve, locking the ball bearings in the switchable clamping assembly inside the correction head. At the same time, it controls the first and second tracks to drive the correction head and the pressure plate to move in opposite directions to synchronously correct the skew at the conveyor front end and the unwinding source.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the synergistic effect of conveyor belt vacuum adsorption and dual-end synchronous dynamic correction, automatic, high-precision, and non-destructive feeding and shearing of metal foil materials are achieved. Integrated into the shearing machine body, it can complete roll loading, material traction, online deviation adjustment, and precise length shearing without manual intervention, significantly improving production efficiency and consistency of shearing dimensions. First, it adopts a conveyor belt with through-holes combined with a negative pressure vacuum chamber, which can generate uniform and flexible adsorption force on thin and easily wrinkled honeycomb carrier foil materials throughout the conveying process, ensuring that they are flat and adhered to the conveying surface, fundamentally avoiding slippage, wrinkling, or surface scratches caused by traditional friction pushing.

[0016] 2. This invention features a two-stage correction system that links the front and rear. The detection mechanism at the end of the conveying process uses multi-point pressure sensors to perceive the contact force distribution at the edge of the foil in real time, accurately identifying the deviation trend and direction. The correction mechanism adopts a pneumatically controlled switchable ball bearing design. During normal conveying, the ball bearing rolls freely to reduce resistance. Under the correction command, it can quickly lock and switch to an active friction pusher to perform immediate lateral correction on the front end of the foil.

[0017] 3. The present invention has a movable pressure plate type roll self-aligning mechanism at the feeding roller end, which is linked with the front-end correction head through the control system. It can synchronously perform reverse compensation movement according to the skew signal, adjust the roll posture from the unwinding source, realize the dual closed-loop control of real-time correction and source correction, and greatly improve the centering and stability of long foil materials in the continuous conveying process.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 11 The present invention provides a technical solution: a hydraulic swing plate shearing machine for processing metal honeycomb carriers with automatic feeding, which can cut large-area metal foil for processing metal honeycomb carriers into strip foils that meet the size requirements, so as to enter the subsequent honeycomb carrier forming process.

[0032] like Figures 1-3 As shown, a horizontal shearing seat 2 is fixedly installed in the middle of the base 1 of the hydraulic swing shearing machine by bolts. When the front end of the metal foil is horizontally conveyed to the shearing seat 2 and exceeds a certain length, the hydraulic swing cutter on the shearing machine can swing to cut off the part of the foil that exceeds the shearing seat 2, thus completing one shearing operation.

[0033] like Figure 6 , Figure 7 As shown, two side plates 3 are symmetrically installed on the feeding side of the base 1. Two drive rollers 4 are rotatably installed between the two side plates 3 via bearings. The two drive rollers 4 are connected by pulleys and belts, enabling them to rotate synchronously. One of the drive rollers 4 is driven by a geared motor. A conveyor belt 5 is wound around the two drive rollers 4. The conveyor belt 5 is an annular belt with through-hole micro-perforations, which can generate negative pressure suction from its interior, serving as the main metal foil pushing and conveying structure.

[0034] Furthermore, such as Figure 5 , Figure 10 As shown, a front support 6 is extended and installed on the feeding side of the base 1. A horizontal feeding roller 7 is welded and installed on the front support 6. The feeding roller 7 has a smooth surface and can load foil rolls. The rolls can rotate on the roller, thereby pulling out the metal foil. At the same time, a guide roller 8 is rotatably installed on the side plate 3. The guide roller 8 is horizontally positioned above the front of the conveyor belt 5. The pulled-out metal foil falls onto the conveyor belt 5 after passing through the guide roller 8 and is conveyed towards the shearing seat 2 by the conveyor belt 5.

[0035] like Figure 5 As shown, the upper part of the conveyor belt 5 has vacuum adsorption capability, which can specifically push thin and easily deflected metal foils, and can flatly adsorb the metal foils onto the belt surface. It can precisely control the feeding length and improve the shearing quality. A vacuum chamber 9 is set between the upper and lower planes of the conveyor belt 5. The vacuum chamber 9 is fixedly installed by the side plate 3, and the air extraction surface of the vacuum chamber 9 is set upward. An air box 10 is embedded in the side plate 3 and connected to the bottom surface of the vacuum chamber 9. At the same time, the air box 10 is connected to the main pipe 11, which is connected to the negative pressure source. The negative pressure source is usually a Roots vacuum pump. Through the operation of the negative pressure source, a negative pressure is generated at the upward opening of the vacuum chamber 9. After ventilation through the micropores of the conveyor belt 5, the metal foils can be adsorbed onto the conveyor belt 5 for conveying.

[0036] like Figure 3 , Figure 4 As shown, the conveyor belt 5 is a ring belt, and there is an installation gap between it and the shear seat 2. This installation gap is filled by the connecting plate 12. The connecting plate 12 is fixedly installed on the shear seat 2 by screws. The bottom surface of the connecting plate 12 is an arc-shaped surface, which can fit the arc-shaped side of the conveyor belt 5. The upper surface of the connecting plate 12 is horizontal and flush with the upper surface of the conveyor belt 5 and the upper surface of the shear seat 2, which can guide the foil on the conveyor belt 5 to the shear seat 2.

[0037] like Figure 4As shown, a skew detection mechanism is further provided on the connecting plate 12 to detect the skewness of the metal foil. The skew detection mechanism includes two symmetrically mounted limiting seats 13 on both sides of the connecting plate 12. The limiting seats 13 are inverted L-shaped structures. At least three movable slots 14 are arranged on the horizontal top surface of the limiting seats 13. The movable slots 14 are arranged along the moving direction of the foil. A hanging shaft 15 is slidably mounted in the movable slot 14. A guide post 16 is rotatably mounted on the hanging shaft 15. The guide post 16 is also arranged along the moving direction of the metal foil. The metal foil entering the connecting plate 12 can contact the guide post 16 on both sides and be guided and limited by the guide post 16. At the same time, at least three pressure sensors 17 are arranged on the limiting seats 13. The pressure sensors 17 are located between each guide post 16 and the limiting seat 13 and can detect the pressure on each guide post 16.

[0038] The pressure range of the pressure sensor 17 is limited. If the current generated by each pressure sensor 17 is within the limited range, it means that the metal foil is being transported along the direction of the guide post 16 and no correction is needed. However, if the current generated by the pressure sensors 17 belonging to the front and rear and the two sides is significantly different, it means that the metal foil has deviated to the side with the larger current and needs to be deflected to the side with the smaller current to ensure the quality of shearing.

[0039] like Figure 8 , Figure 9 As shown, a left-right pushing correction mechanism is provided for the metal foil falling on the conveyor belt 5. The correction mechanism includes a bracket 18 horizontally installed between two side plates 3. The bracket 18 is located near the connecting plate 12. A first track 19 is fixedly installed in the middle of the bracket 18 by bolts. A correction head 20 is driven and installed on the first track 19. The correction head 20 can move along the direction of the first track 19, that is, perpendicular to the direction of the foil movement, to push and correct the metal foil.

[0040] The bottom of the correction head 20 is equipped with a ball bearing 21 that rotates omnidirectionally via a spherical joint. The bottom of the ball bearing 21 can rest on the metal foil. When the metal foil is being conveyed normally by the conveyor belt 5, the ball bearing 21 can roll normally without affecting the movement of the foil.

[0041] like Figure 9As shown, a spring guide rod 22 is installed on the upper part of the correction head 20. Two sets of spring guide rods 22 are symmetrically arranged. Two completely symmetrical semi-circular slide blocks 23 are movably installed on both sides of the correction head 20 through the two sets of spring guide rods 22. The bottom of the semi-circular slide block 23 is integrally formed with a clamp 24. Under the elastic force of the spring guide rod 22, the two semi-circular slide blocks 23 converge inward, which will drive the clamp 24 at the bottom to act on the ball 21, clamping and fixing the ball 21, so that it loses its ability to rotate. Under this condition, when the correction head 20 moves, the ball 21 can move along with it while remaining relatively stationary. Through friction, it drives the metal foil to shift left and right, thereby having the correction capability.

[0042] Furthermore, a rotating shaft 25 is rotatably mounted on the top of the correction head 20 via a rotating groove. A fan blade 26 is fixedly mounted on the rotating shaft 25. The fan blade 26 is located inside the correction head 20 and can rotate within it. Meanwhile, two hanging balls 27 are symmetrically arranged at the bottom end of the rotating shaft 25. The hanging balls 27 are connected to the rotating shaft 25 via hanging ropes and are located inside the semi-circular slide seat 23.

[0043] like Figure 8 As shown, the correction head 20 is connected to an air extraction pipe 28 near the fan blade 26, and an air inlet is provided on the other side away from the air extraction pipe 28. The air extraction pipe 28 is a flexible hose, and its other end is connected to the auxiliary pipe 29 through a flange. The auxiliary pipe 29 is fixedly installed on the side plate 3 and is connected to the main pipe 11. A solenoid valve is also provided on the auxiliary pipe 29. Therefore, when the negative pressure source is working and the conveyor belt 5 is performing adsorption conveying, it can also generate airflow in the correction head 20 through the auxiliary pipe 29 and the air extraction pipe 28, thereby causing the fan blade 26 to rotate and driving the rotating shaft 25 to rotate rapidly. As the centrifugal force rotates, the hanging ball 27 rotates accordingly. Under the action of centrifugal force, the hanging ball 27 is thrown to both sides, which can generate external pressure from the inside of the semi-circular slide 23. This causes the semi-circular slide 23 to drive the chuck 24 to move outward, releasing the ball 21 so that it can rotate freely without affecting the movement of the foil. Conversely, when the metal foil is skewed and needs to be adjusted, the negative pressure source and the conveyor belt 5 stop working, the rotating shaft 25 also stops rotating, and the ball 21 returns to the state of being fixed at the bottom of the correction head 20. By moving the correction head 20, the ball 21 can be used to push and adjust the foil.

[0044] like Figure 10 , Figure 11 As shown, the correction head 20 is mainly used to correct the deviation at the front end of the metal foil. An adjustment mechanism is also set on the feeding roller 7 for the foil roll to achieve the effect of correction from the source. The two work synchronously to control the foil conveying angle.

[0045] like Figure 10As shown, an elastic element 30 is provided at one end of the feeding roller 7 connected to the front support 6. The elastic element 30 is usually a spring fitted on the feeding roller 7. At the same time, a limiting plate 31 is movably sleeved on the feeding roller 7. The limiting plate 31 and the elastic element 30 are fixedly connected by pins. The limiting plate 31 is used to support and limit the foil roll on one side of the feeding roller 7, and the elastic force is used to squeeze the roll to the other side.

[0046] Furthermore, at the open end of the feeding roller 7 away from the front support 6, that is, at the end where the foil roll is fitted onto the feeding roller 7, a slide rail 32 is provided below it. The slide rail 32 is fixed to the workshop floor by expansion screws. A vertical slide block 33 is slidably installed on the upper limit of the slide rail 32. A horizontal second track 34 is fixedly installed on the top of the slide block 33 by screws. The direction of the second track 34 is consistent with the direction of the feeding roller 7. A pressure plate 35 is driven and installed on the second track 34. The top of the pressure plate 35 is provided with a sleeve hole, so the pressure plate 35 can be fitted onto the feeding roller 7. When driven by the second track 34, it can push the foil roll and drive the roll to move and adjust against the elastic force of the elastic element 30.

[0047] like Figure 10 , Figure 11 As shown, in order to facilitate the loading and unloading of the roll, the position of the second track 34 and the pressure plate 35 is changed by moving the slide 33. When it is necessary to load or unload foil, the slide 33 is moved to the side away from the feeding roller 7, and the roll is loaded from the open end of the feeding roller 7. After loading is completed, the slide 33 is pushed back to the bottom of the feeding roller 7. At this time, the second track 34 drives the pressure plate 35 to move to the middle. The pressure plate 35 can push the roll against the elastic force to the middle position of the feeding roller 7. Then the foil of the roll is pulled out, and after passing through the guide roller 8, it is attached to the conveyor belt 5 to complete the initial loading work. Then, the subsequent automatic loading work can be carried out by the suction pull of the conveyor belt 5.

[0048] like Figure 11 As shown, foot-operated locking structures are provided at both ends of the slide rail 32, which can fix the slide block 33 on both sides near and away from the feeding roller 7, respectively. The locking structure includes a base 36 fixed to the side of the slide rail 32 by screws. The base 36 is provided with an upward-facing spring pin 37. The spring pin 37 can pop up and connect with the bottom insertion hole of the slide block 33, thereby fixing the slide block 33 at both ends, which is convenient for loading and unloading foil or using the pressure plate 35. At the same time, a foot pedal 38 is welded to the spring pin 37. By stepping on the foot pedal 38, the spring pin 37 can be depressed, disengaging from the slide block 33 and thus unlocking it, which is more convenient for single-person operation and will not affect the loading and unloading of the foil roll.

[0049] Both the first track 19 and the second track 34 are electrically controlled linear tracks with the same movement control precision. When the pressure sensor 17 detects that the foil is skewed, the control system can generate a control signal to drive the first track 19 and the second track 34 in opposite directions. The correction head 20 and the pressure plate 35 move in opposite directions. The correction head 20 pushes the front end of the foil directly left and right, while the pressure plate 35 pushes or releases the roll. Combined with the elastic force of the elastic element 30, the roll moves left and right, thereby correcting the skewed metal foil. During the automatic feeding and cutting process, the foil is cut stably and with high quality.

[0050] In use, the invention is as follows: First, a roll loaded with metal foil is mounted on the feeding roller 7. The slide block 33 is pushed to move it away from the feeding roller 7 and locked using the foot pedal 38. After loading the roll, the slide block 33 is pushed back to its base 36 and locked below the feeding roller 7 by the spring pin 37. Then, the pressure plate 35 on the second track 34 is driven to move, pushing the roll to engage with the elastic element 30 and position it in the middle of the feeding roller 7. Next, the front end of the foil is pulled out and laid flat on the upper surface of the conveyor belt 5 after being guided by the guide roller 8. The negative pressure source is activated, and the vacuum chamber 9 generates an adsorption force through the micropores of the conveyor belt 5, adsorbing the foil flatly onto the surface of the conveyor belt 5. At the same time, the reduction motor drives the drive roller 4, which drives the conveyor belt 5 to stably transport the foil towards the shearing seat 2. When the front end of the foil passes the connecting plate 12, its two sides contact each guide post 16. The pressure sensor 17 detects the pressure value at each point in real time and transmits it to the control system. If the data indicates that the foil is deviated, the control system immediately issues an instruction. The negative pressure source is paused, the conveyor belt 5 is braked, and the solenoid valve of the secondary pipe 29 is closed. The fan blade 26 inside the correction head 20 stops rotating, and the hanging ball 27 is reset. Under the action of the spring guide rod 22 inside the semi-circular slide 23, the two clamps 24 converge inward to lock the ball 21. Then, the first track 19 drives the correction head 20 to move laterally, using the friction of the locked ball 21 to push the front end of the foil material for lateral correction. At the same time, the second track 34 drives the pressure plate 35 to move in the opposite direction, driving the overall axial micro-adjustment of the roll to correct the unwinding angle from the source. After the correction is completed, the negative pressure source and the conveyor belt 5 are restarted, the solenoid valve is opened, and the airflow drives the fan blade 26 to rotate, causing the hanging ball 27 to be thrown out centrifugally, opening the semi-circular slide 23 and the clamps 24, and the ball 21 returns to a free rotation state. The foil material continues to be conveyed to the shearing seat 2. When its front end exceeds the set length, the hydraulic system drives the swing blade holder to swing down to complete the shearing. The entire feeding, correction, conveying, and shearing process is carried out automatically in a cycle until the roll material is used up.
