Description

Technical Field

[0001] This utility model relates to the field of metal composite plate processing technology, and in particular to a milling device for metal composite plates. Background Technology

[0002] Metal composite panels are made of multiple layers of materials. The top and bottom layers are high-purity aluminum alloy plates, and the middle layer is a low-density polyethylene core. Metal composite panels have good weather resistance, high strength, are easy to maintain, have good plasticity, are impact resistant, can reduce the load on buildings, and have good seismic resistance. However, metal composite panels cannot be produced in large areas, so they need to be assembled and welded together. In order to improve the strength of the weld, the edges of the metal composite panels need to be milled to increase the welding area.

[0003] Patent No. 201110257292.3 discloses a special milling power head for trimming the edges of metal composite plates, including a connecting bracket, a frame, a speed-regulating gearbox, a motor, a spindle guide device, a clamping spring, a limiting guide device, and a round nose end mill assembly. The connecting bracket is bolted to the frame, the spindle guide device is welded to the frame, and the motor is bolted to the speed-regulating gearbox. The motor and speed-regulating gearbox are then mounted as a whole on the spindle guide device. The clamping spring is inserted from the lower part of the spindle, and the round nose end mill assembly is installed at the lower end of the spindle. When trimming the edges of the metal composite plate, the round nose end mill assembly can only mill a relatively thin layer. Furthermore, the limiting guide device and the guide disc restrict the depth of the round nose end mill assembly, making it impossible to mill stably. When the milling width exceeds the round nose end mill assembly, the milling efficiency will also decrease. Utility Model Content

[0012] As a preferred embodiment, the conveying device is a belt conveyor.

[0013] After adopting the above technical solution, the effect of this utility model is as follows: A milling device for metal composite plates includes a base, on which a conveying device for conveying metal composite plates is provided. The milling device includes a first milling mechanism mounted on the base and located on one side of the metal composite plate. The first milling mechanism includes a first milling base mounted on the base. A first milling lifting seat is vertically and vertically mounted on the first milling base. A first milling height adjusting mechanism for adjusting the height of the first milling lifting seat is provided on the first milling base. A first milling cutter driven to rotate by a first milling power head is fixedly mounted on the first milling lifting seat. The first milling cutter rotates around a vertical rotation center line. The first milling cutter contacts the upper part of the edge of the metal composite plate. A clamping device for pressing the metal composite plate is also installed on the machine base above the conveying device. First, the conveying device drives the metal composite plate to the first milling mechanism. Then, the first milling height adjustment mechanism adjusts the height of the first milling lifting seat, causing the first milling cutter to contact the upper part of the edge of the metal composite plate. Next, the first milling power head drives the first milling cutter to mill the upper part of the edge of the metal composite plate. Simultaneously, the clamping device presses the metal composite plate to ensure stable and accurate milling. This milling device can adjust its height arbitrarily after pressing the metal composite plate during milling to control the milling depth, ensuring accurate and stable milling.

[0014] Furthermore, the pressing device includes a guide column fixed on the machine base, a pressing seat is vertically and vertically mounted on the guide column, and several pressing roller groups are rotatably mounted on the pressing seat. The pressing roller groups and the conveying surface of the conveying device form a conveying channel that facilitates the passage of the metal composite plate. The machine base is provided with a pressing seat lifting adjustment mechanism to adjust the height of the pressing seat. The lifting adjustment mechanism drives the pressing seat to lift and lower, thereby controlling the pressing roller groups to press the metal composite plate. The guide column ensures accurate and stable lifting and lowering, guaranteeing accurate and smooth conveying of the metal composite plate.

[0015] Furthermore, the clamping seat lifting and adjusting mechanism includes an upstream screw jack and a downstream screw jack. The lifting seats of the upstream and downstream screw jacks are respectively fixedly connected to the clamping seat. A synchronous connecting rod connects the upstream and downstream screw jacks. The upstream or downstream screw jack is equipped with an operating handwheel or a driving power device. By operating the handwheel or driving power device, the worm gear on the upstream or downstream screw jack is driven to rotate, thereby causing the worm wheel to rotate as well. This allows the worm wheel to move up and down along the screw, thus changing the height of the clamping seat. The structure is simple and the operation is stable.

[0016] Furthermore, since the first milling height adjustment mechanism includes a first milling screw and nut mechanism, the screw of the first milling screw and nut mechanism is rotatably mounted on the first milling base and is provided with a first adjusting handwheel, and the nut of the first milling screw and nut mechanism is fixedly connected to the first milling lifting seat; by rotating the first adjusting handwheel, the screw can be driven to rotate, thereby driving the nut to move up and down, thereby driving the first milling lifting seat to move up and down effectively, controlling the milling height of the first milling cutter. The structure is simple and the adjustment is accurate and convenient.

[0017] Furthermore, since the first milling base is horizontally slidably mounted on the machine base, and a first milling distance adjustment mechanism is provided between the machine base and the first milling base, the first milling distance adjustment mechanism drives the first milling base to move closer to or away from the edge of the metal composite plate; in this way, the milling width of the first milling cutter on the edge of the metal composite plate can be controlled, thereby improving milling flexibility.

[0018] Furthermore, the milling device also includes a second milling mechanism, which is located downstream of the first milling mechanism. The second milling mechanism includes a second milling base mounted on a machine base, a second milling lifting seat vertically mounted on the second milling base, and a second milling height adjustment mechanism for adjusting the height of the second milling lifting seat. A second milling cutter driven to rotate by a second milling power head is fixedly mounted on the second milling lifting seat. The second milling cutter rotates around a horizontal rotation center line and performs secondary milling on the upper edge of the metal composite plate. After the first milling mechanism completes milling, the second milling height adjustment mechanism controls the lifting of the second milling lifting seat to allow the second milling cutter to effectively and accurately approach the metal composite plate. Then, the second milling power head can drive the second milling cutter to rotate around the horizontal rotation center line, effectively improving the efficiency of milling the thickness of the metal composite plate.

[0019] Furthermore, since the second milling base is horizontally slidably mounted on the machine base, and a second milling distance adjustment mechanism is provided between the machine base and the second milling base, the second milling distance adjustment mechanism drives the second milling base to move closer to or away from the edge of the metal composite plate; similarly, it can control the milling width of the second milling cutter on the edge of the metal composite plate, thereby improving milling flexibility.

[0020] Furthermore, since the conveying device is a belt conveyor, the conveying is stable and reliable, improving the conveying efficiency of the metal composite plate. Attached Figure Description

[0028] The present invention will be further described in detail below through specific embodiments.

[0029] like Figures 1 to 5 As shown, a milling device for a metal composite plate includes a base 1, on which a conveying device for conveying the metal composite plate 25 is provided. The milling device includes a first milling mechanism mounted on the base 1 and located on one side of the metal composite plate 25. The first milling mechanism includes a first milling base 2 mounted on the base 1. A first milling lifting seat 3 is vertically and vertically mounted on the first milling base 2. A first milling height adjustment mechanism for adjusting the height of the first milling lifting seat 3 is provided on the first milling base 2. A first milling cutter 4 driven to rotate by a first milling power head is fixedly mounted on the first milling lifting seat 3. The first milling cutter 4 rotates around a vertical rotation center line and contacts the upper part of the edge of the metal composite plate 25. A clamping device for pressing the metal composite plate 25 is also mounted on the base 1 above the conveying device.

[0030] In this embodiment, the pressing device includes a guide column 5 fixed on the base 1. A pressing seat 6 is vertically and vertically mounted on the guide column 5. A plurality of pressing roller groups 7 are rotatably mounted on the pressing seat 6. A conveying channel is formed between the pressing roller groups 7 and the conveying surface of the conveying device to facilitate the passage of the metal composite plate 25. The base 1 is provided with a pressing seat 6 lifting adjustment mechanism to adjust the height of the pressing seat 6. The guide column 5 can ensure that the pressing seat 6 can be accurately and stably lifted and lowered. The pressing roller groups 7 can press the metal composite plate 25 as a whole and convey it effectively as the pressing seat 6 descends. The pressing roller groups 7 can follow the metal composite plate 25 to assist in the conveying and ensure the pressing force.

[0031] like Figure 1 As shown, the lifting and adjusting mechanism of the pressing seat 6 includes an upstream screw jack 8 and a downstream screw jack 9. The lifting seats of the upstream screw jack 8 and the downstream screw jack 9 are respectively fixedly connected to the pressing seat 6. A synchronous connecting rod 10 connects the upstream screw jack 8 and the downstream screw jack 9. The upstream screw jack 8 or the downstream screw jack 9 is equipped with an operating handwheel 11 or a drive power device. The drive power device can be a drive motor. By installing the operating handwheel 11 or the drive motor on the upstream screw jack 8, the worm gear of the upstream screw jack 8 can be driven to rotate, which in turn drives the worm wheel to rotate, thereby allowing the lifting seat to rise and fall along the screw. The synchronous connecting rod 10 can also synchronously drive the worm gear of the downstream screw jack 9, thereby allowing the lifting seats of the upstream screw jack 8 and the downstream screw jack 9 to rise and fall synchronously, so that the pressing roller group 7 can accurately press the metal composite plate 25. The upstream screw jack 8 and the downstream screw jack 9 are existing structures on the market, so they will not be described in detail in this article.

[0032] like Figure 2 As shown, the first milling height adjustment mechanism includes a first milling screw and nut mechanism 12. The screw of the first milling screw and nut mechanism 12 is rotatably mounted on the first milling base 2 and is provided with a first adjusting handwheel 13. The nut of the first milling screw and nut mechanism 12 is fixedly connected to the first milling lifting seat 3. The first milling lifting seat 3 is a slider slide rail structure, so it can accurately lift and slide. By rotating the first adjusting handwheel 13, the screw can be driven to rotate, which can drive the nut to move up and down, thereby driving the first milling lifting seat 3 to effectively lift and lower, controlling the milling height of the first milling cutter 4. The first milling power head is a first milling motor 14. The first milling motor 14 is fixedly mounted on the first lifting seat. The first milling motor 14 and the first milling cutter 4 are provided with a transmission structure, which facilitates the rotation of the first milling cutter 4 around the vertical rotation center line. The structure is simple and the adjustment is accurate and convenient.

[0033] In this embodiment, the first milling base 2 is horizontally slidably mounted on the machine base 1. A first milling distance adjustment mechanism is provided between the machine base 1 and the first milling base 2. The first milling distance adjustment mechanism drives the first milling base 2 to move closer to or away from the edge of the metal composite plate 25. The first milling distance adjustment mechanism is a first distance adjustment screw and nut mechanism 15. The first milling base 2 of the first distance adjustment screw and nut mechanism 15 supports the first lifting seat, and the screw of the first distance adjustment screw and nut mechanism 15 is perpendicular to the conveying direction of the metal composite plate 25. In this way, the first distance adjustment handwheel 26 drives the screw of the first distance adjustment screw and nut mechanism 15 to rotate, thereby causing the nut to rotate. This allows the first milling base 2 of the first distance adjustment screw and nut mechanism 15 to move laterally, which can control the milling width of the first milling cutter 4 on the edge of the metal composite plate 25, thereby improving milling flexibility.

[0034] like Figure 3 As shown, the milling device further includes a second milling mechanism, which is located downstream of the first milling mechanism. The second milling mechanism includes a second milling base 16 mounted on the base 1. A second milling lifting seat 17 is vertically and vertically mounted on the second milling base 16. A second milling height adjustment mechanism is provided on the second milling base 16 to adjust the height of the second milling lifting seat 17. A second milling cutter 18, driven to rotate by a second milling power head, is fixedly mounted on the second milling lifting seat 17. The second milling cutter 18 rotates around a horizontal rotation centerline and performs secondary milling on the upper edge of the metal composite plate 25. The second milling mechanism has the same structure as the first milling mechanism, and the second milling height adjustment mechanism is a second milling screw and nut mechanism. 19. The lead screw of the second milling screw and nut mechanism 19 is rotatably mounted on the second milling base 16 and is provided with a second adjusting handwheel 20. The nut of the second milling screw and nut mechanism 19 is fixedly connected to the second milling lifting seat 17. The second milling lifting seat 17 is a slider rail structure, so it can accurately lift and slide. By rotating the second adjusting handwheel 20, the lead screw can be driven to rotate, which can drive the nut to move up and down, thereby driving the second milling lifting seat 17 to effectively lift and lower, controlling the milling height of the second milling cutter 18. The second milling power head is the second milling motor 21. The second milling motor 21 is fixedly mounted on the second lifting seat. The second milling motor 21 and the second milling cutter 18 are provided with a transmission structure, which facilitates the rotation of the second milling cutter 18 around the horizontal center line. The structure is simple and the adjustment is accurate and convenient.

[0035] In this embodiment, the second milling base 16 is horizontally slidably mounted on the machine base 1. A second milling distance adjustment mechanism is provided between the machine base 1 and the second milling base 16. The second milling distance adjustment mechanism drives the second milling base 16 to move closer to or away from the edge of the metal composite plate 25. The second milling distance adjustment mechanism is a second distance adjustment screw and nut mechanism 22. The second milling base 16 of the second distance adjustment screw and nut mechanism 22 supports the second lifting seat, and the screw of the second distance adjustment screw and nut mechanism 22 is perpendicular to the conveying direction of the metal composite plate 25. In this way, the second distance adjustment handwheel 27 drives the screw of the second distance adjustment screw and nut mechanism 22 to rotate, thereby causing the nut to rotate. This allows the second milling base 16 of the second distance adjustment screw and nut mechanism 22 to move laterally, which can control the milling width of the second milling cutter 18 on the edge of the metal composite plate 25, thereby improving milling flexibility.

[0036] Furthermore, the conveying device is a belt conveyor, with a belt conveyor wheel 24 for driving the conveyor belt 23 fixedly installed on the base 1. The belt conveyor wheel 24 is equipped with a conveying motor, which cooperates with the pressure roller group 7 to effectively convey the conveyor.

[0037] The working principle of this embodiment is as follows: First, the metal composite plate 25 is placed on the conveyor belt 23. Then, the handwheel 11 is operated to drive the worm gear of the upstream screw jack 8 to rotate, which causes the lifting seats of the upstream screw jack 8 and the downstream screw jack 9 to rise and fall, 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 cutter 4. 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 cutter 4 is close to the edge of the metal composite plate 25 for the first milling step. Then, the metal composite plate 25 is conveyed to the second milling cutter 18. 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 cutter 18 is close to the edge of the metal composite plate 25 for the second milling step.

[0038] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
