Description

Technical Field

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

[0002] Existing cutting equipment for aluminum profiles mostly performs end face flat cutting, that is, the profiles are only cut according to the length requirement. During the cutting process, no large pieces of waste are generated, only a small amount of debris is produced, which has little impact on the processing working environment and is easy to handle.

[0003] With the expansion of the uses of profiles, such as in outdoor simple disassembly and assembly houses, large profiles are used. There is a processing requirement for chamfering at both ends of the profiles for corner splicing. When the cut surfaces at both ends of the profiles are not parallel to each other, existing cutting equipment is difficult to solve the problem of large pieces of remaining materials generated after cutting. At the same time, for large profiles, their own profile wall thickness is large, and large vibrations will be generated during the cutting process. When the profiles are not firmly clamped, it is easy to cause uneven cutting. At the same time, considering that the transportation of the profile processing pipeline is mostly a roller conveyor device, and to avoid scratching the surface of the profile during transportation, the surface of the existing rollers is mostly an elastic rubber surface, so that the existing conventional pressing and clamping method of the rollers has a certain degree of looseness. ]Summary of the Invention

Both the roller seat and the flat pressing block are provided with a flat pushing drive mechanism, and the flat pushing drive mechanism respectively drives the roller and the flat pressing block to move towards the lateral positioning base plate.

[0017] As an improvement of the above solution, the lateral pushing mechanism further includes a flat pushing base for vertically installing the flat pushing drive mechanism. The flat pushing base is vertically provided with a plurality of flat pushing slide rails for slidably connecting the flat pressing blocks, and the flat pressing blocks move towards the lateral positioning base plate along the flat pushing slide rails under the drive of their respective flat pushing drive mechanisms.

[0025] Implementing the present invention has the following beneficial effects:

[0026] The embodiment of the present invention discloses an aluminum material cutting machine for large widths, including a clamping device and a cutting assembly. The workpiece in the cutting area is cut by the cutting assembly, and the clamping devices are arranged on both sides of the cutting area. Therefore, the waste generated by cutting can directly fall from the cutting area, thereby avoiding the difficulty of collecting the remaining materials following the transportation assembly line and also avoiding the random falling of the remaining materials during the transportation and movement process. In particular, small remaining materials are likely to fall on the roller transportation line.

[0027] The cutting assembly includes a cutting device, a horizontal rotation device for adjusting the cutting angle, a cutting translation device for driving the horizontal rotation device to translate, and a cutting lifting device for driving the cutting translation device to lift. The cutting device is installed on the horizontal rotation device. Therefore, the cutting angle of the cutting device can be controlled by controlling the horizontal rotation device. Moreover, the cutting device translates along the transportation direction of the workpiece through the cutting translation device, and the cutting position can be adjusted according to the processing requirements, thus avoiding the problem of loosening the workpiece clamping and changing the cutting position by moving the workpiece, and further improving the production efficiency.

[0028] Moreover, the clamping device includes a support table, a lifting pressure plate, support rollers for docking and transporting workpieces into the cutting area, and a first lifting drive mechanism for driving the support rollers to lift. The support rollers are arranged on both sides of the support table, and the lifting pressure plate is correspondingly located above the support table. Therefore, before the workpiece is clamped, the support rollers can be raised to avoid friction between the workpiece and the support table during the movement of the workpiece. Correspondingly, when the workpiece moves to the preset position, the support rollers descend, and the lifting pressure plate cooperates with the support table to stably clamp and fix the profile, thereby improving the cutting quality.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings.

[0035] See Figure 1 、 2 and 3, an embodiment of the present invention provides a cutting machine for large-width aluminum materials, including a clamping device 5 and a cutting assembly. The workpiece in the cutting area is cut by the cutting assembly, and the clamping device 5 is arranged on both sides of the cutting area;

[0036] Among them, the cutting assembly includes a cutting device 1, a horizontal rotation device 2 for adjusting the cutting angle, a cutting translation device 3 for driving the horizontal rotation 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 rotation device 2, and the cutting device 1 translates along the transportation direction of the workpiece through the cutting translation device 3 to adjust the cutting position;

[0037] The clamping device 5 includes a support table 51, a lifting pressure plate 52, support rollers 53 for docking and transporting workpieces into the cutting area, and a first lifting drive mechanism for driving the support rollers 53 to lift. The support rollers 53 are distributed on both sides of the support table 51, and the lifting pressure plate 52 is correspondingly located above the support table 51.

[0038] Specifically, a preset distance is left between the support tables 51 of the clamping devices 5 on both sides to form the cutting area. A collection device is provided below the cutting area to collect the cutting scraps falling in the cutting area. Preferably, the collection device is a container 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.

[0039] The horizontal rotation device 2 includes a lateral cantilever 21 driven by the cutting translation device 3, a horizontal rotation table 22 for installing the cutting device 1, and a first motor 23 for driving the horizontal rotation table 22 to rotate. The first motor 23 is installed on the lateral cantilever 21, thereby providing a moving space for the rotation of the cutting device 1. Preferably, the cutting translation device 3 and the cutting lifting device 4 can be screw drive devices, which include a drive base, a drive screw installed on the drive base, and a screw drive plate for installing the driven part. The screw drive plate is provided with a drive nut adapted to the drive screw.

[0040] In order to improve the cutting accuracy of the workpiece, the clamping device further includes a lateral positioning mechanism 54. The lateral positioning mechanism 54 includes a lateral positioning base plate 541 and a lateral pushing mechanism for pushing the workpiece towards the lateral positioning base plate 541. The lateral positioning base plate 541 is provided with vertical rollers 5411 for contacting the workpiece to reduce the side wear of the workpiece. The vertical rollers 5411 and the lateral pushing mechanism are respectively arranged on both sides of the support table 51. Therefore, before the workpiece is cut, the workpiece can be pressed towards the lateral positioning base plate 541 through the lateral pushing mechanism, so that the lateral position of the workpiece can be determined according to the position limitation of the preset vertical rollers 5411.

[0041] Moreover, due to the large self-weight of the large workpiece, if the workpiece is directly dragged in contact with the surface of the support table 51, the bottom surface of the workpiece will be severely damaged. Therefore, the clamping device further includes a clamping workbench 55 provided with a support table 51, and the table surface of the clamping workbench 55 is provided with a plurality of lifting holes 551 for the lifting movement of the support rollers 53;

[0042] The first lifting drive mechanism includes a first lifting base 56 and a first telescopic mechanism 57 for driving the lifting of the first lifting base 56. The first lifting base 56 is provided with a plurality of the support rollers 53, so as to synchronously drive the lifting of each support roller 53 by driving the lifting of the first lifting base 56. Therefore, before the workpiece is cut, the support rollers 53 can be lifted above the top surface of the support table 51 through the first telescopic mechanism 57 to avoid contact and wear between the workpiece and the support table 51. Correspondingly, when the workpiece reaches the preset processing position, the support rollers 53 can be driven to descend below the top surface of the support table 51 to ensure that the support table 51 and the lifting pressure plate 52 can stably clamp the workpiece. The clamping workbench 55 is provided with a first lifting slide rail 553 for guiding the lifting movement of the first lifting base 56, and one side of the first lifting base 56 is slidably connected to the first lifting slide rail 553.

[0043] For the drive of the lifting pressure plate 52, the clamping device further includes a downward pressure drive plate 521 connected to the lifting pressure plate 52 and a downward pressure telescopic mechanism 522 for driving the lifting of the downward pressure drive plate 521. The table surface of the clamping workbench 55 is provided with a downward pressure moving hole 552 for the downward pressure drive plate 521 to pass through and move. The lifting pressure plate 52 is provided with an avoidance hole 523 for avoiding the vertical roller 5411. With such a setting, it is possible to avoid arranging the driving devices related to the lifting pressure plate 52 above the lifting pressure plate 52, thereby preventing interference with the working space of the adjacent cutting device 1. The lateral positioning substrate 541 is provided with a downward pressure slide rail 5412 for guiding the lifting movement of the downward pressure drive plate 521, and the downward pressure drive plate 521 is slidably connected to the downward pressure slide rail 5412. Preferably, both the first telescopic mechanism 57 and the downward pressure telescopic mechanism 522 are pneumatic telescopic rod mechanisms in the prior art.

[0044] The lateral pushing mechanism includes a roller seat 58 provided with rollers 581, a flat pressing block 59, and a lateral pushing drive mechanism 589. The roller seat 58 and the flat pressing block 59 are both equipped with the lateral pushing drive mechanism 589 to drive the rollers 581 and the flat pressing block 59 to move towards the lateral positioning substrate 541 respectively. Therefore, during the process of the workpiece moving towards the cutting device 1, the roller seat 58 with rollers 581 can be driven separately to contact the workpiece first, so that the trajectory of the workpiece moving towards the cutting device 1 is within a reasonable range, avoiding large lateral offsets of the workpiece during movement. After the workpiece moves to the preset position, the flat pressing block 59 is driven to press against the workpiece to realize the limitation and fixation of the lateral position of the workpiece.

[0045] In order to deal with workpieces with non-standard rectangular shapes, such as workpieces with uneven side walls or weak lateral pressure resistance structures, the lateral pushing mechanism further includes a lateral pushing base 591 for vertically installing the lateral pushing drive mechanism 589. The lateral pushing base 591 is vertically and spacedly provided with a plurality of lateral pushing slide rails 592 for slidably connecting the flat pressing blocks 59. Each flat pressing block 59 is driven by its respective lateral pushing drive mechanism 589 to move along the lateral pushing slide rails 592 towards the lateral positioning substrate 541, so that selective lateral pressure driving can be performed according to the distribution of the lateral force-bearing structure of the actual workpiece. The lateral pushing drive mechanism 589 is preferably a pneumatic telescopic rod mechanism in the prior art.

[0046] Since the cut end of the workpiece is not a flat surface after cutting, if the workpiece driven by power directly ejects it, it is easy to damage the workpiece and at the same time cause unstable movement and feeding of the workpiece. Therefore, the cutting machine for large-width aluminum materials further includes a discharging device for moving the cut workpiece to a preset transportation device;

[0047] See Figure 4 and Figure 5 , for the convenience of description, the clamping devices on both sides of the cutting device 1 are respectively a feeding fixing device and a discharging fixing device, and along the transportation direction of the workpiece, it successively passes through the feeding fixing device, the cutting area, and the discharging fixing device; among them, Figure 4 For the convenience of showing the structure, some support rollers 53 and support tables 51 are not shown.

[0048] The discharging device includes a material transfer rack 6, an inclined pushing mechanism 7 arranged on the material transfer rack 6, and a material transfer driving mechanism 8 for driving the material transfer rack 6 to move back and forth between the discharging fixing device and a preset transportation device. Preferably, the material transfer driving mechanism 8 can be a screw drive mechanism in the prior art, or a meshing driving method between a rack and a gear. That is, a motor is installed on the material transfer rack 6, a fixed rack and a fixed rack for installing the rack are arranged along the transportation direction of the workpiece. Correspondingly, the fixed rack is provided with a material transfer slide rail slidably connected to the material transfer rack 6, and a gear meshing with the rack is installed on the output shaft of the motor. When the motor drives the gear to rotate, the material transfer rack 6 can be driven to move along the material transfer slide rail.

[0049] The inclined pushing mechanism 7 includes an inclined pushing block 71 and an inclined pushing telescopic rod 72 for driving the inclined pushing block 71. The telescopic trajectory of the inclined pushing telescopic rod 72 is inclined relative to the lateral positioning substrate 541, so that the moving trajectory of the inclined pushing block is inclined relative to the moving trajectory of the flat pressing block of the discharging fixing device. That is, the inclined pushing block 71 can move from the right side of the moving trajectory of the flat pressing block 59 of the discharging fixing device to the left side of the moving trajectory of the flat pressing block 59, so as to approach the cutting position of the workpiece. With such a setting, even small pieces of workpieces can be stably and accurately moved to a preset position. Preferably, the inclined pushing telescopic rod 72 is driven by a pneumatic telescopic rod mechanism.

[0050] See Figure 5 , the discharging device further includes a pressing mechanism 9 for pressing the workpiece and a clamping mechanism 10 for laterally clamping the workpiece. Along the transportation direction of the workpiece, the material transfer rack 6 is sequentially distributed with a pressing mechanism 9, an inclined pushing mechanism 7 and a clamping mechanism 10. Therefore, the pressing mechanism 9 can perform preliminary clamping and traction movement on the workpiece according to the clamping situation of the workpiece, and the setting of the clamping mechanism 10 can clamp both sides of the workpiece when the workpiece leaves the lateral positioning substrate 541 of the discharging fixing device and there is enough clamping surface, so as to prevent the workpiece from falling.

[0051] The pressing mechanism 9 includes a lower pressing plate 91 and a pneumatic telescopic rod mechanism for driving the lower pressing plate to press down. The clamping mechanism 10 includes a fixed clamping plate 101, a movable clamping plate 102 and a screw drive mechanism for driving the movable clamping plate to move towards 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 substrate 541. Preferably, the screw drive mechanism for driving the movable clamping plate 102 to move towards the fixed clamping plate can also be replaced with a pneumatic telescopic rod mechanism in the prior art. By connecting the cylinder and the telescopic rod of the pneumatic telescopic rod mechanism to the movable clamping plate 102 and the material transfer rack 6 respectively, the clamping movement between the fixed clamping plate 101 and the movable clamping plate 102 can be realized.

[0052] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
