Description

Technical Field

[0001] The invention relates to the technical field of metal composite plate production, in particular to an automatic edge milling and flanging machine for metal composite plates. Background Art

[0002] Metal composite panels are made of multiple layers of materials. The upper and lower layers are high-purity aluminum alloy plates, and the middle layer is a low-density polyethylene core plate. Metal composite panels have good weather resistance, high strength, easy maintenance, good plasticity, impact resistance, can reduce the load on buildings, and have good shock resistance. However, metal composite panels cannot be produced in a large area, so metal composite panels need to be assembled and welded. In order to improve the firmness of welding, it is necessary to mill the edges of the metal composite panels to increase the welding area, and it is also necessary to flanging to make the two metal composite panels fit together to make the assembly welding more firm.

[0003] Patent No. 201110257292.3 discloses a special milling power head for trimming metal composite plates, including a connecting bracket, a frame, a speed regulating gearbox, a motor, a spindle guide device, a compression spring, a limit guide device and a round nose milling cutter disc group; the connecting bracket is connected to the frame by bolts, the spindle guide device is welded to the frame, the motor is fixed to the speed regulating gearbox by bolts, and then the motor and the speed regulating gearbox are integrally installed on the spindle guide device, the compression spring is inserted from the lower part of the spindle, and the round nose milling cutter disc group is installed at the lower end of the spindle. When trimming the edge of the metal composite plate, the round nose milling cutter disc group can only mill a thinner layer, and the limit guide device and the guide disc limit the sinking depth of the round nose milling cutter disc group, making it impossible to mill stably, and when the milling width exceeds the round nose milling cutter disc group, the milling efficiency will also deteriorate.

[0004] After milling, the plate needs to be folded and transported to a designated flanging station. The flanging station can only perform flanging in one direction. When flanging in other directions is required, it needs to be moved to another flanging station, which increases the complexity of processing and affects production efficiency.

[0023] The inner flanging device comprises an inner flanging bracket which is laterally slidably mounted on the machine base and is located outside the composite plate, the machine base is provided with an inner flanging transverse adjustment mechanism for laterally adjusting the inner flanging bracket, and the inner flanging bracket is provided with an inner flanging roller group for conveniently pressing the vertical side plate portion of the composite plate inward;

[0024] The outer flanging device includes a lower outer flanging bracket which is laterally slidably installed on the machine base and is located on the outer side of the composite plate. The machine base is provided with an outer flanging lateral adjustment mechanism for laterally adjusting the lower outer flanging bracket. At least two lower positioning rollers are rotatably installed on the lower outer flanging bracket. The central axis of the lower positioning roller is vertically arranged. An upper outer flanging bracket is installed on the pressing seat through an upper outer flanging vertical adjustment mechanism. At least one horizontally arranged outer flanging squeezing roller and at least one horizontally arranged outer flanging pressing roller are rotatably installed on the upper outer flanging bracket. At least two lower positioning rollers cooperate with the outer flanging squeezing roller and the outer flanging pressing roller respectively. The outer end of the outer flanging squeezing roller is provided with a The conical extrusion portion of the vertical edge plate is extruded from the inside to the outside, and the outer flanging pressing roller is located downstream of the outer flanging pressing roller. The outer flanging pressing roller squeezes the vertical edge plate portion that is turned outward from top to bottom to make it horizontal; first, the metal composite plate is conveyed to the first milling mechanism through the conveying device, and at the same time, the clamping device clamps the metal composite plate for conveying, and then the first milling height adjustment mechanism adjusts the height of the first milling lifting seat so that the first milling tool contacts the upper part of the edge of the metal composite plate, and then the first milling power head drives the first milling tool to mill the upper part of the edge of the metal composite plate, and then the milled metal composite plate continues to be conveyed to the lower flanging rack, and the metal composite plate passes through the upstream lower flanging roller to make the metal The edge of the composite plate is initially raised, and then passes through the middle flanging in turn, so that the edge of the metal composite plate is gradually raised until it is vertical. At this time, the edge of the metal composite plate is transported in cooperation with the downstream lower flanging roller, and then the inner flanging or outer flanging is performed after the lower flanging is completed. When the inner flanging is performed, it is transported to the inner flanging bracket, and the inner flanging lateral adjustment mechanism adjusts the inner flanging bracket to move lateraly, and the inner flanging roller group approaches the metal composite plate. As the conveying device conveys the inner flanging roller group, it squeezes the metal composite plate to flanging inward, so that the vertical side plate of the metal composite plate is flanging inward; when the outer flanging is performed, it is transported to the lower outer flanging bracket, and the outer flanging lateral adjustment mechanism drives the lower outer flanging bracket to approach the metal composite plate, so that the lower positioning roller The vertical edge plate portion of the metal composite plate is pressed against the vertical edge plate portion, and then the upper outer flanging vertical adjustment mechanism drives the upper outer flanging bracket to descend, so that the outer flanging extrusion roller and the outer flanging pressure roller are close to the metal composite plate and cooperate with the lower positioning roller at the same time. The conical extrusion portion of the outer flanging extrusion roller squeezes the vertical edge plate portion from the inside to the outside, and at the same time the lower positioning roller presses against part of the vertical edge plate portion. As the metal composite plate is continuously conveyed, the vertical edge plate portion of the metal composite plate continuously tilts outward, and then the outer flanging pressure roller presses the metal composite plate downward to make the vertical edge plate portion roll horizontal, completing the outward flanging; the automatic milling and flanging mechanism can realize milling, vertical flanging, inward or outward flanging during the conveying process of the metal composite plate, so as to be suitable for different production processes.

[0025] Since the first milling base is installed on the machine base for horizontal sliding, a first milling spacing adjustment mechanism is arranged between the machine base and the first milling base, and the first milling spacing adjustment mechanism drives the first milling base to approach or move away from the edge of the metal composite plate, and the first milling height adjustment mechanism includes a first milling screw nut mechanism, the screw of the first milling screw nut mechanism is rotatably installed on the first milling base and is provided with a first adjusting handwheel, and the nut of the first milling screw nut mechanism is fixedly connected to the first milling lifting seat; the milling width of the edge of the metal composite plate by the first milling tool is controlled by the first milling spacing adjustment mechanism, thereby improving the milling flexibility, and at the same time, the first adjusting handwheel is used to drive the screw to rotate to drive the nut to move up and down, thereby driving the first milling lifting seat to effectively move up and down, and controlling the milling height of the first milling tool, the structure is simple, and the adjustment is accurate and convenient.

[0026] Furthermore, since the milling device further includes a second milling mechanism, the second milling mechanism is arranged downstream of the first milling mechanism, the second milling mechanism includes a second milling base installed on the machine base for horizontal sliding, a second milling lifting seat is vertically lifted and installed on the second milling base, a second milling height adjustment mechanism for adjusting the height of the second milling lifting seat is arranged on the second milling base, a second milling tool driven to rotate by a second milling power head is fixedly installed on the second milling lifting seat, the second milling tool rotates around the horizontal rotation center line, and the second milling tool performs secondary milling on the upper edge of the metal composite plate A second milling spacing adjustment mechanism is arranged between the machine base and the second milling base, and the second milling spacing adjustment mechanism drives the second milling base to approach or move away from the edge of the metal composite plate; after the milling of the first milling mechanism is completed, the second milling height adjustment mechanism is used to control the lifting of the second milling lifting seat to make the second milling tool effectively and accurately approach the metal composite plate, and then the second milling power head can drive the second milling tool to rotate around the horizontal rotation center line, effectively improving the efficiency of milling the thickness of the metal composite plate; the second milling spacing adjustment mechanism controls the milling width of the edge of the metal composite plate by the second milling tool, thereby improving the milling flexibility.

[0027] Furthermore, since the lower flanging frame includes a lower horizontal fixing plate, an upper vertical fixing plate and a plurality of lower mounting plates, the lower horizontal fixing plate is fixed to the machine base, the upper vertical fixing plate is fixed to the clamping seat by fixing bolts, the upper vertical fixing plate is provided with a plurality of vertically extending lower vertical strip holes, the fixing bolts are constrained in the lower vertical strip holes, the lower end of the lower mounting plate is fixedly connected to the lower horizontal fixing plate, the upper end of the lower mounting plate is fixedly connected to the upper vertical fixing plate, the lower mounting plate is an arc-shaped mounting plate, and the lower flanging The roller seat is provided with a sleeve hole which is sleeved on the arc-shaped mounting plate, and the lower flanging roller seat is provided with a locking structure for locking the lower flanging roller seat; the lower horizontal fixing plate and the upper vertical fixing plate can ensure that the lower mounting plate is accurately and firmly installed, and the upper vertical fixing plate slides along the lower vertical strip hole to adjust the position on the clamping seat, which can ensure that after the clamping seat is raised and lowered, the upper vertical fixing plate will not follow the lifting and lowering, thereby ensuring accurate installation; the lower flanging roller seat can slide along the arc-shaped mounting plate through the sleeve hole, and the position can be effectively fixed through the locking structure, and the adjustment is simple and convenient.

[0028] Since there are three middle lower flanging rollers, the angles between the central axes of the three middle lower flanging rollers and the horizontal plane are 22.5°, 45° and 67.5° respectively, ensuring a smooth transition during flanging.

[0029] Since the structure of the inner flanging bracket is the same as that of the lower flanging bracket, the inner flanging roller group includes an upstream inner flanging roller at the most upstream, a downstream inner flanging roller at the most downstream, and at least two intermediate inner flanging rollers in the middle. The central axis of the upstream inner flanging roller is vertically arranged, the central axis of the downstream inner flanging roller is horizontally arranged, and the central axis of the intermediate inner flanging roller gradually decreases the intersection angle with the horizontal plane according to the conveying direction of the metal composite plate; the upstream inner flanging roller can effectively support the vertical side plate portion of the metal composite plate, and then the intermediate inner flanging roller can effectively tilt the vertical side plate portion, thereby continuously increasing the tilt angle, and finally the downstream inner flanging roller completes the inner flanging to ensure that the inner flanging is accurate and stable.

[0030] Since each of the lower positioning rollers is rotatably mounted on a corresponding positioning roller seat, each positioning roller seat is mounted on the lower flanging bracket through a positioning lifting and adjusting mechanism; since the lower positioning roller needs to be higher than the upper surface of the metal composite plate when the outer flanging extrusion roller is extruding the metal composite plate to ensure that the folded edge during flanging will not be lower than the upper surface of the metal composite plate, as the flanging angle increases, the lower positioning roller can be lowered until the vertical edge plate portion supported is flush with the upper surface of the metal composite plate, and the positioning lifting and adjusting mechanism can be used to control the lower positioning roller to be at the height of the vertical edge plate portion of the metal composite plate, so that it can cooperate with the corresponding outer flanging extrusion roller and the outer flanging pressing roller.

[0031] Furthermore, since the outer flanging extrusion roller is installed on the upper outer flanging bracket through a horizontal adjustment structure, the outer flanging extrusion roller can be effectively moved horizontally through the horizontal adjustment structure, so that the vertical side plate portion of the conical extrusion portion close to the metal composite plate can be extruded outward, so that the vertical side plate portion gradually flanging outwards until it is horizontal, thereby improving the flanging effect.

[0032] Furthermore, since the horizontal adjustment mechanism includes a central screw fixed on the upper outer flanging bracket and arranged horizontally, an adjusting screw sleeve is threadedly installed on the central screw, the outer flanging extrusion roller is rotatably installed on the adjusting screw sleeve, the outer end of the adjusting screw sleeve is provided with a screwing portion and exposed from the outer flanging extrusion roller, and a compression spring is provided between the adjusting screw sleeve and the upper outer flanging bracket; the extension distance of the outer flanging extrusion roller can be changed by rotating the adjusting screw sleeve, thereby increasing or decreasing the extrusion inclination amplitude of the vertical side plate portion of the metal composite plate, and at the same time, the compression spring can ensure that the adjusting screw sleeve and the central screw can be effectively locked after rotation, thereby improving the effect of the outer flanging of the metal composite plate.

[0033] Furthermore, since the outer flanging pressing roller is also installed on the upper outer flanging bracket through the horizontal adjustment structure, the outer flanging pressing roller can also effectively adjust the lateral distance to flatten the vertical edge plate portions of the metal composite plates of different widths, thereby improving practicality.

[0060] Two first edge milling mechanisms and a second edge milling mechanism are arranged on the machine base 1, so that the first edge milling mechanism and the second edge milling mechanism can be used alternately in pairs, thereby improving the use efficiency.

[0062] Furthermore, the lower mounting plate 28 is an arc-shaped mounting plate, and the lower flanging roller seat 29 is provided with a sleeve hole 37 which is sleeved on the arc-shaped mounting plate, and the lower flanging roller seat 29 is provided with a locking structure for locking the lower flanging roller seat 29; the lower flanging roller seat 29 can slide in an arc along the arc-shaped mounting plate through the sleeve hole 37, so that the angle of the lower flanging roller can be changed, and the position can be effectively fixed through the locking structure, and the adjustment is simple and convenient.

[0063] In this embodiment, the number of the intermediate lower flanging rollers 32 is three, and the angles between the central axes of the three intermediate lower flanging rollers 32 and the horizontal plane are 22.5°, 45° and 67.5° respectively; together with the upstream lower flanging roller 30 and the downstream lower flanging roller 31, the metal composite plate 25 can be stably transitioned and folded in sequence after being conveyed by the conveying device, so that the flanging can be stable and accurate, thereby improving the flanging accuracy.

[0064] like Figure 1 and Figure 7As shown, the structure of the inner flanging bracket 40 is the same as that of the lower flanging bracket, and the inner flanging roller group includes an upstream inner flanging roller 48 at the most upstream, a downstream inner flanging roller 49 at the most downstream, and at least two intermediate inner flanging rollers 50 in the middle, the central axis of the upstream inner flanging roller 48 is vertically arranged, the central axis of the downstream inner flanging roller 49 is horizontally arranged, and the central axis of the intermediate inner flanging roller 50 gradually decreases in accordance with the intersection angle between the conveying direction of the metal composite plate 25 and the horizontal plane; the inner flanging bracket 40 is provided with There are a number of inner mounting plates 54 arranged at intervals. Since the vertical side plate portion 41 of the metal composite plate 25 needs to be flanged inward, the upstream inner flanging roller 48 changes its angle inward when changing its angle toward the downstream inner flanging roller 49. The upstream inner flanging roller 48 can effectively support the vertical side plate portion 41 of the metal composite plate 25, and then the middle inner flanging roller 50 can effectively tilt the vertical side plate portion 41, thereby continuously increasing the tilt angle, and finally the downstream inner flanging roller 49 completes the inner flanging to ensure that the inner flanging is accurate and stable.

[0065] Furthermore, the inner mounting plate 54 is an arc-shaped mounting plate, and the inner flanging roller seat is provided with a sleeve hole 37 which is sleeved on the arc-shaped mounting plate, and the inner flanging roller seat is provided with a locking structure for locking the inner flanging roller seat; the inner flanging roller seat can slide along the arc-shaped mounting plate through the sleeve hole 37, and then the position can be effectively fixed through the locking structure, and the adjustment is simple and convenient; the locking structure includes a fixing nut 38 welded to the outer side of the inner flanging roller seat, and a tightening bolt 39 is threadedly connected to the fixing nut 38, and the tightening bolt 39 tightens the outer end face of the inner mounting plate 54; the tightening bolt 39 can be rotated to support the outer end face of the inner mounting plate 54, thereby effectively fixing the inner flanging roller, and the structure is simple.

[0066] In this embodiment, the inner flange lateral adjustment mechanism 51 is a screw nut mechanism; a synchronously sliding lower inner horizontal fixing plate 52 is fixedly installed on the screw nut mechanism, and an upper inner vertical fixing plate 53 is slidably installed on the clamping seat 6. Several inner mounting plates 54 are fixedly installed between the lower inner horizontal fixing plate 52 and the upper inner vertical fixing plate 53. The upper inner vertical fixing plate 53 is fixed to the clamping seat 6 by fixing bolts 36. Several vertically extending vertical adjustment strip holes 55 are provided on the upper inner vertical fixing plate. The fixing bolts 36 are constrained in the vertical adjustment strip holes 55. The fixing plate 53 slides along the vertical adjustment strip hole 55 to adjust its position on the clamping seat 6, which can ensure that after the clamping seat 6 is raised or lowered, the upper inner vertical fixing plate 53 will not follow the raising or lowering, thereby ensuring accurate installation; at the same time, when the screw nut mechanism is adjusted to move laterally, the mounting plate will move laterally. It is only necessary to loosen the fixing bolt 36 so that the upper inner vertical fixing plate 53 is not fixed on the clamping seat 6 and can move away from the metal composite plate 25. Driving the inner flanging roller group to move closer to and away from the metal composite plate 25 is simple, quick and easy to operate; the screw nut mechanism is an existing structure on the market, so it is not described in detail in this article.

[0067] Furthermore, the number of the intermediate inner flanging rollers 50 is three, and the intersection angles between the central axis and the horizontal plane are 67.5°, 45° and 22.5° respectively; together with the upstream inner flanging roller 48 and the downstream inner flanging roller 49, the metal composite plate 25 can be stably transitioned and folded in sequence after being conveyed by the conveying device, so that the flanging can be stable and accurate, thereby improving the flanging accuracy.

As the flanging angle increases, the lower positioning roller 43 can be lowered until the vertical side plate portion 41 supported is flush with the upper surface of the metal composite plate 25. The lower positioning roller 43 can be controlled to be at the height of the vertical side plate portion 41 of the metal composite plate 25 through the positioning lifting and adjusting mechanism, so that it can cooperate with the corresponding outer flanging extrusion roller 45 and the outer flanging pressing roller 46; the positioning lifting and adjusting mechanism is a positioning screw elevator 58, and the positioning screw elevator 58 is provided with an artificial turntable 59 to drive the lower positioning roller 43 to a suitable height.

[0070] Furthermore, the upper outer flange vertical adjustment mechanism includes an upper vertical strip hole 60 arranged on the clamping seat 6, and the upper flanging bracket is fixed to the clamping seat 6 by bolts constrained in the upper vertical strip hole 60; the upper outer flange bracket 44 is adjusted in height by raising and lowering along the upper vertical strip hole 60, so as to change the height of the outer flange extrusion roller 45 and the outer flange pressing roller 46 to adapt to the thickness of different metal composite plates 25, and at the same time avoid outward flanging, with a simple structure and easy use.

[0071] like Figure 8 and Fig. 9 As shown, the outer flanging extrusion roller 45 is installed on the upper outer flanging bracket 44 through a horizontal adjustment structure. The outer flanging extrusion roller 45 can be effectively moved horizontally through the horizontal adjustment structure, so that the tapered extrusion portion 47 can be squeezed outward close to the vertical side plate portion 41 of the metal composite plate 25, so that the vertical side plate portion 41 gradually flanging outward until it is horizontal, thereby improving the flanging effect.

[0072] In this embodiment, the horizontal adjustment mechanism includes a central screw 61 fixed on the upper outer flanging bracket 44 and arranged horizontally, an adjusting screw sleeve 62 is threadedly installed on the central screw 61, the outer flanging extrusion roller 45 is rotatably installed on the adjusting screw sleeve 62, the outer end of the adjusting screw sleeve 62 is provided with a screwing portion 63 and exposed from the outer flanging extrusion roller 45, and a compression spring 64 is provided between the adjusting screw sleeve 62 and the upper outer flanging bracket 44; a rotating bearing 65 is provided between the adjusting screw sleeve 62 and the outer flanging extrusion roller 45 to ensure stable rotation, and the extension distance of the outer flanging extrusion roller 45 can be changed by rotating the adjusting screw sleeve 62, thereby increasing or decreasing the extrusion inclination amplitude of the vertical side plate portion 41 of the metal composite plate 25, and at the same time, the compression spring 64 can ensure that the adjusting screw sleeve 62 and the central screw 61 can be effectively locked after rotation, thereby improving the effect of flanging the metal composite plate 25.

[0073] Furthermore, the outer flanging pressing roller is also installed on the upper outer flanging bracket 44 through a horizontal adjustment structure; therefore, the internal structure of the outer flanging pressing roller 46 is the same as the structure of the outer flanging extrusion roller 45, and an adjusting screw sleeve 62 is also rotatably installed in the outer flanging pressing roller 46, and the adjusting screw sleeve 62 is also rotatably installed on another center screw 61, and the outer flanging pressing roller 46 and the adjusting screw sleeve 62 are also rotatably connected through a rotating bearing 65, so that the outer flanging pressing roller 46 can rotate stably, and at the same time, the outer flanging pressing roller 46 can also move axially along the center screw 61.

[0074] The conveying device is a belt conveying device. A belt conveying wheel 24 for driving a conveying belt 23 for conveying is fixedly mounted on the machine base 1. A conveying motor is arranged on the belt conveying wheel 24, so that the belt conveying wheel 24 cooperates with the pressing roller group 7 to effectively convey.

[0075] The working principle of the present invention is as follows: first, the metal composite plate 25 is placed on the conveyor belt 23, and then the hand wheel 11 is operated to drive the worm of the upstream screw elevator 8 to rotate so that the lifting seats of the upstream screw elevator 8 and the downstream screw elevator 9 can be lifted and lowered, driving the pressing roller group 7 on the pressing seat 6 to press down the metal composite plate 25 and convey it to the first milling tool 4, and then the first spacing adjustment screw nut mechanism 15 and the first milling screw nut mechanism 12 are used to adjust the position of the first milling base 2 and the first milling lifting seat 3, so that the first milling tool 4 is close to the edge of the metal composite plate 25, and the first step of milling is performed, and then the metal composite plate 25 is conveyed to the second milling tool 18, and the second spacing adjustment screw nut mechanism 22 and the second milling screw nut mechanism 19 are used to adjust the position of the second milling base 16 and the second milling lifting seat 17, so that the second milling tool 18 is close to the edge of the metal composite plate 25, and the second step of milling is performed; then it is conveyed to the upstream lower flanging roller 30, and the upstream lower flanging roller 30, the middle The intermediate lower flanging roller 32 and the downstream lower flanging roller 31 are adjusted to the corresponding angles, and the metal composite plate 25 is automatically flanging after being conveyed, and then the inner flanging or outer flanging is performed, and then the metal composite plate 25 is conveyed to the inner flanging bracket 40, and the upstream inner flanging roller 48, the intermediate inner flanging roller 50 and the downstream inner flanging roller 49 are adjusted to the corresponding angles in sequence. When the metal composite plate 25 is conveyed to complete the inner flanging, or the metal composite plate 25 is directly conveyed to the lower outer flanging bracket 42, the outer flanging lateral adjustment mechanism The mechanism 56 drives the lower positioning roller 43 to press against the vertical side plate portion 41 of the metal composite plate 25, and at the same time, the positioning screw elevator 58 drives the lower positioning roller 43 to rise and fall to a suitable height, and the upper flanging bracket adjusts the height of the upper flanging extrusion roller and the upper flanging pressure roller through the upper vertical strip hole 60 to be close to the metal composite plate 25, and rotates the adjusting screw sleeve 62 to make the conical extrusion portion 47 of the upper flanging extrusion roller squeeze the vertical side plate portion 41 of the metal composite plate 25, and continuously tilts until the upper flanging pressure roller is flattened to complete the outer flanging.
