Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to a cutting machine for large-width aluminum materials. Background Art

[0002] The existing aluminum profile cutting equipment is mostly used for end face cutting, that is, the profile is cut only according to the length requirements. The cutting process will not produce large pieces of waste, only a small amount of debris, which has little impact on the processing working environment and is easy to handle.

[0003] As the use of profiles expands, such as simple outdoor disassembly and assembly houses, large profiles will be used, and the ends of the profiles need to be cut for corner splicing. When the cross-sections at both ends of the profile are not parallel to each other, it is difficult for existing cutting equipment to solve the large pieces of residual material produced after cutting. At the same time, for large profiles, the wall thickness of the profile itself is large, and a large vibration will be generated during the cutting process. When the profile is not clamped stably, it is easy to cause uneven cutting. At the same time, considering that the processing line transportation of profiles is mostly a roller transportation device, and in order to avoid scratches on the surface of the profile during transportation, the surface of the existing roller is mostly an elastic rubber surface, so that the downward pressing clamping method of the existing conventional matching roller has a certain degree of looseness. Summary of the invention

The first lifting base is equipped with a plurality of support rollers, so that the lifting and lowering of each support roller can be synchronously driven by driving the first lifting base to lift and lower. The clamping workbench is provided with a first lifting slide rail for guiding the lifting movement of the first lifting base, and one side of the first lifting base is slidably connected to the first lifting slide rail.

[0009] As an improvement of the above scheme, the clamping device also includes a pressing driving plate connected to the lifting and lowering plate and a pressing telescopic mechanism for driving the pressing driving plate to lift and lower. The table top of the clamping workbench is provided with a pressing activity hole for the pressing driving plate to pass through, and the lifting and lowering plate is provided with an avoidance hole adapted to the vertical roller bar. The lateral positioning base plate is provided with a pressing slide rail for guiding the lifting movement of the pressing drive plate, and the pressing drive plate is slidably connected to the pressing slide rail.

[0010] As an improvement of the above scheme, the lateral pushing mechanism includes a roller seat with rollers and a flat pressing block, and the roller seat and the flat pressing block are both equipped with a pushing driving mechanism, and the pushing driving mechanism drives the rollers and the flat pressing block to move toward the lateral positioning substrate.

[0011] As an improvement of the above-mentioned scheme, the lateral push mechanism also includes a push base for vertically installing the push drive mechanism, and the push base is vertically spaced with a plurality of push rails for slidingly connecting the pressure blocks. The pressure blocks are driven by their respective push drive mechanisms and move toward the lateral positioning substrate along the push rails.

[0012] As an improvement of the above scheme, the horizontal rotation device includes a transverse cantilever driven by the cutting translation device, a horizontal rotating table for mounting the cutting device, and a first motor for driving the horizontal rotating table to rotate, wherein the first motor is mounted on the transverse cantilever.

The telescopic trajectory of the oblique push telescopic rod is inclined relative to the lateral positioning substrate, so that the active trajectory of the oblique push block is inclined relative to the active trajectory of the flat pressing block of the discharge fixing device.

[0014] As an improvement of the above solution, the discharging device further includes a pressing mechanism for pressing down the workpiece and a clamping mechanism for laterally clamping the workpiece; Along the transport direction of the workpiece, the material transfer rack is sequentially provided with the pressing mechanism, the oblique pushing mechanism and the clamping mechanism.

DETAILED DESCRIPTION

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1 , 2 and 3, an embodiment of the present invention provides a cutting machine for large width aluminum materials, comprising a clamping device 5 and a cutting assembly, through which a workpiece in a cutting area is cut, and the clamping device 5 is provided on both sides of the cutting area; The cutting assembly includes a cutting device 1, a horizontal rotating device 2 for adjusting a cutting angle, a cutting translation device 3 for driving the horizontal rotating device 2 to translate, and a cutting lifting device 4 for driving the cutting translation device 3 to lift. The cutting device 1 is installed on the horizontal rotating device 2. The cutting device 1 is translated along the transport direction of the workpiece by the cutting translation device 3 to adjust the cutting position. The clamping device 5 includes a support platform 51, a lifting and pressing plate 52, a support roller 53 for docking and transporting the workpiece into the cutting area, and a first lifting and driving mechanism for driving the support roller 53 to lift and lower. The support roller 53 is distributed on both sides of the support platform 51, and the lifting and pressing plate 52 is correspondingly located above the support platform 51.

[0021] Specifically, a preset spacing is left between the support platforms 51 of the clamping devices 5 on both sides to form the cutting area, and a collecting device is provided below the cutting area to collect the cutting residues dropped from the cutting area. Preferably, the collecting device is a container that is adapted to the shape and size of the cutting area. The cutting device 1 includes a saw blade and a saw blade motor for driving the saw blade to rotate.

[0022] The horizontal rotating device 2 includes a horizontal cantilever 21 driven by the cutting translation device 3, a horizontal rotating platform 22 for mounting the cutting device 1, and a first motor 23 for driving the horizontal rotating platform 22 to rotate, wherein the first motor 23 is mounted on the horizontal cantilever 21, thereby providing a movable space for the rotation of the cutting device 1. Preferably, the cutting translation device 3 and the cutting lifting device 4 can be screw transmission devices, which include a transmission base, a transmission screw mounted on the transmission base, and a screw driving plate for mounting the driven screw, wherein the screw driving plate is provided with a transmission nut adapted to the transmission screw.

[0023] In order to improve the accuracy of workpiece cutting, the clamping device also includes a lateral positioning mechanism 54, which includes a lateral positioning base plate 541 and a lateral push mechanism for pushing the workpiece toward the lateral positioning base plate 541. The lateral positioning base plate 541 is provided with a vertical roller 5411 for contacting the workpiece to reduce the side wear of the workpiece. The vertical roller 5411 and the lateral push mechanism are respectively arranged on both sides of the support table 51. Therefore, before the workpiece is cut, the workpiece can be pressed toward the lateral positioning base plate 541 by the lateral push mechanism, so that the workpiece can be determined in the lateral position according to the position limit of the preset vertical roller 5411.

[0024] Moreover, due to the heavy weight of a large workpiece, if the workpiece directly touches and drags on the surface of the support table 51, the bottom surface of the workpiece will be seriously damaged. Therefore, the clamping device also includes a clamping workbench 55 for mounting the support table 51, and the table surface of the clamping workbench 55 is provided with a plurality of lifting holes 551 for the lifting and lowering of the support roller 53; The first lifting drive mechanism includes a first lifting base 56 and a first telescopic mechanism 57 for driving the first lifting base 56 to lift and lower. The first lifting base 56 is provided with a plurality of support rollers 53, so that the lifting and lowering of each support roller 53 can be synchronously driven by driving the lifting and lowering of the first lifting base 56. Therefore, before the workpiece is cut, the support rollers 53 can be lifted to the top surface of the support platform 51 by the first telescopic mechanism 57 to avoid contact and wear between the workpiece and the support platform 51. Accordingly, when the workpiece reaches the preset processing position, the support rollers 53 can be driven to drop below the top surface of the support platform 51 to ensure that the support platform 51 and the lifting and lowering plate 52 can stably clamp the workpiece. The clamping workbench 55 is provided with a first lifting rail 553 for guiding the lifting and lowering activities of the first lifting base 56, and one side of the first lifting base 56 is slidably connected to the first lifting rail 553.

[0025] For driving the lifting and lowering plate 52, the clamping device further comprises a pressing driving plate 521 connected to the lifting and lowering plate 52 and a pressing telescopic mechanism 522 for driving the pressing driving plate 521 to move up and down. The tabletop of the clamping workbench 55 is provided with a pressing activity hole 552 for the pressing driving plate 521 to pass through, and the lifting and lowering plate 52 is provided with an avoidance hole 523 for avoiding the vertical roller 5411. Such a configuration can avoid the driving device related to the lifting and lowering plate 52 being arranged above the lifting and lowering plate 52, thereby preventing interference with the working space of the adjacent cutting device 1. The lateral positioning base plate 541 is provided with a pressing slide rail 5412 for guiding the lifting and lowering activity of the pressing driving plate 521, and the pressing driving plate 521 is slidably connected to the pressing slide rail 5412. Preferably, the first telescopic mechanism 57 and the pressing telescopic mechanism 522 are both pneumatic telescopic rod mechanisms of the prior art.

[0026] The lateral push mechanism includes a roller seat 58 with a roller 581, a flat pressing block 59 and a push driving mechanism 589. The roller seat 58 and the flat pressing block 59 are both equipped with the push driving mechanism 589 to drive the roller 581 and the flat pressing block 59 to move toward the lateral positioning substrate 541. Therefore, in the process of the workpiece moving toward the cutting device 1, the roller seat 58 with the roller 581 can be driven alone to contact the workpiece first, so that the trajectory of the workpiece moving toward the cutting device 1 is within a reasonable range, avoiding a large lateral deviation of the workpiece during the movement. When the workpiece moves to the preset position, the flat pressing block 59 is driven to press against the workpiece to achieve the limitation and fixation of the lateral position of the workpiece.

[0027] In order to target non-standard rectangular workpieces, such as those with uneven side walls or structures with weak lateral pressure bearing capacity, the lateral push mechanism also includes a push base 591 for vertically mounting the push drive mechanism 589, and the push base 591 is vertically spaced with a plurality of push rails 592 for slidingly connecting the pressure blocks 59. Each pressure block 59 moves toward the lateral positioning base plate 541 along the push rails 592 under the drive of its own push drive mechanism 589, so that selective lateral pressure driving can be performed according to the distribution of the lateral force bearing structure of the actual workpiece. The push drive mechanism 589 is preferably a pneumatic telescopic rod mechanism of the prior art.

[0028] Since the cut end of the workpiece is not flat after cutting, if it is directly ejected by the workpiece driven by power, it is easy to damage the workpiece, and it will also cause the workpiece to move and be sent out unstably. Therefore, the cutting machine for large-width aluminum materials also includes a discharge device for moving the cut workpiece to a preset transportation device; See also Figure 4 and Figure 5 For the convenience of description, the clamping devices on both sides of the cutting device 1 are respectively a feed fixture and a discharge fixture. Along the transportation direction of the workpiece, it passes through the feed fixture, the cutting area and the discharge fixture in sequence; wherein, Figure 4 In order to facilitate the display of the structure, part of the support rollers 53 and the support platform 51 are not shown.

[0029] The material discharging device includes a material transfer frame 6, an oblique push mechanism 7 arranged on the material transfer frame 6, and a material transfer driving mechanism 8 for driving the material transfer frame 6 to and from the material discharging fixing device and the preset transportation equipment. Preferably, the material transfer driving mechanism 8 can be a screw transmission mechanism of the prior art, or a meshing drive method between a rack and a gear can be adopted, that is, a motor is installed on the material transfer frame 6, a fixed rack and a fixed frame for installing the rack are set along the transportation direction of the workpiece, and accordingly, the fixed frame is provided with a material transfer slide rail slidably connected to the material transfer frame 6, and the output shaft of the motor is equipped with a gear meshing with the rack. When the motor drives the gear to rotate, the material transfer frame 6 can be driven to move along the material transfer slide rail.

[0030] The oblique push mechanism 7 includes an oblique push block 71 and an oblique push telescopic rod 72 for driving the oblique push block 71. The telescopic track of the oblique push telescopic rod 72 is inclined relative to the lateral positioning base plate 541, so that the moving track of the oblique push block is inclined relative to the moving track of the flat pressing block of the discharging fixture, that is, the oblique push block 71 can be moved from the right side of the moving track of the flat pressing block 59 of the discharging fixture to the left side of the moving track of the flat pressing block 59, so as to approach the cutting position of the workpiece. With such an arrangement, even a small section of the workpiece can be stably and accurately moved to a preset position. Preferably, the oblique push telescopic rod 72 is driven by a pneumatic telescopic rod mechanism.

[0031] See also Figure 5 The discharge device further includes a pressing mechanism 9 for pressing down the workpiece and a clamping mechanism 10 for laterally clamping the workpiece. Along the transport direction of the workpiece, the material transfer frame 6 is sequentially provided with the pressing mechanism 9, the oblique pushing mechanism 7 and the clamping mechanism 10. Therefore, the pressing mechanism 9 can perform preliminary clamping, pulling and moving of the workpiece according to the clamping condition of the workpiece, and the setting of the clamping mechanism 10 can clamp both sides of the workpiece after the workpiece leaves the lateral positioning base plate 541 of the discharge fixture and when there is enough clamping surface, so as to prevent the workpiece from falling.

[0032] The pressing mechanism 9 includes a pressing plate 91 and a pneumatic telescopic rod mechanism for driving the pressing plate downward, and the clamping mechanism 10 includes a fixed clamping plate 101, a movable clamping plate 102 and a screw transmission mechanism for driving the movable clamping plate to move toward the fixed clamping plate. Preferably, the side end surface of the fixed clamping plate 101 is flush with the side end surface of the lateral positioning base plate 541. Preferably, the screw transmission mechanism for driving the movable clamping plate 102 to move toward the fixed clamping plate can also be replaced by a pneumatic telescopic rod mechanism of the prior art, and the cylinder and the telescopic rod of the pneumatic telescopic rod mechanism are respectively connected to the movable clamping plate 102 and the material transfer frame 6, so that the clamping activity between the fixed clamping plate 101 and the movable clamping plate 102 can be realized.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
