in order to overcome the defects, the invention provides a metal cutting device for door and window manufacture.
Specifically, bridge cut-off aluminium alloy material loading:
firstly, the aluminum profile is placed on a conveying frame 41 of the feeding part 4, the conveying belt drives the aluminum profile to move towards the conveying groove 13 by means of self friction force, when the aluminum profile slides to the upper part of the guide plate 42, the inclined design of the guide plate 42 is beneficial to smooth and slow sliding of the aluminum profile to the joint of the conveying belt and the workbench 11, then the telescopic rod 43 stretches upwards, the electric telescopic plate 44 slides towards the interior of the workbench 11, the telescopic rod 43 is driven to be attached to the outer surface of the aluminum profile, the aluminum profile is driven to move slowly into the conveying groove 13 (according to the cutting length requirement, the electric baffle sliding inside the workbench is limited and adjusted and fixed by the positioning pin, and then the cutting length is determined). Secondly, the hydraulic telescopic rod inside the driving unit 45 pushes the aluminum profile to slide along the inner wall of the conveying chute 13 (the width of the conveying chute 13 is larger than that of the aluminum profile, and the aluminum profile processing of different sizes in a certain range is met), until the end part of the outer surface of the aluminum profile is tightly attached to the electric baffle, meanwhile, the clamping piece 3 transversely fixes the outer surface of the aluminum profile, and the pressing unit 143 vertically fixes the outer surface of the aluminum profile (the pressing unit 143 is preferably an air cylinder).
Cutting the broken bridge aluminum profile:
after the clamping piece 3 and the pressing unit 143 fix the outer surface of the aluminum profile, the hydraulic telescopic rod inside the lifting unit 16 drives the lifting plate 21 to move upwards (the outer surface of the lifting plate 21 is in sliding connection with the inner sliding groove formed in the inner wall of the processing cavity 12), the cutting unit 22 is detachably arranged on the upper surface of the lifting plate 21 (the saw blades on the two groups of cutting units 22 are installed at 90 degrees and can be finely adjusted), the two groups of saw blades rotating at high speed move upwards synchronously, sequentially pass through the cutting groove 15 and cut the broken bridge aluminum profile on the upper surface of the opposite object plate 14, and as the waste broken bridge aluminum profile above the through hole 141 is always acted by the downward pressure of the pressing unit 143, the position of the waste broken bridge aluminum profile is always kept constant, the deformation of cutting openings is avoided (the broken bridge aluminum profile on two sides of the waste broken bridge aluminum profile is always acted by the acting force of the clamping piece 3), finally the pressing unit 143, the clamping piece 3 and the electric baffle are reset, the pushing unit 144 drives the waste broken bridge aluminum profile to slide to fall into the through hole 141 rapidly, the hydraulic telescopic rod inside the driving unit 45 pushes the waste broken bridge aluminum profile to slide along the inner wall of the upper surface of the aluminum profile to slide along the upper surface of the aluminum profile 13, and the cut aluminum profile is continuously separated from the cut groove 13, and the cut out of the cut aluminum profile is continuously and separated from the cut groove is continuously and separated from the outer surface is continuously. According to the invention, the cutting part 2 is matched with the clamping piece 3 and the pressing machine set 143 to cut the aluminum profile at one time, compared with the traditional automatic cutting device, most of the cutting device adopts two machine heads to alternately cut and discharge, when the saw blade on the first machine head is used for cutting the broken bridge aluminum profile at 45 degrees, the mechanical arm is used for pulling back the broken bridge aluminum profile, and the saw blade on the second machine head is used for cutting the end part of the redundant profile with the opposite angle at 45 degrees, so that the bevel ports at two ends of the cut profile are symmetrical.
In order to meet the requirements of processing aluminum profiles of different sizes in a certain range, the width of the material conveying groove 13 is larger than that of the aluminum profiles, and as the material placing plate 14 is arranged in the middle of the material conveying groove 13 and is used for cutting a carrying surface of the aluminum profiles (the upper surface of the material placing plate 14 is flush with the bottom of the inner wall of the material conveying groove 13), a disconnection part exists between the material conveying grooves 13, when the aluminum profiles slide along the inner wall of the material conveying groove 13, the width of the material conveying groove 13 is larger than that of the aluminum profiles, the aluminum profiles are easy to deviate in the sliding process, and particularly when the aluminum profiles pass through the upper surface of the material placing plate 14, the end parts of the aluminum profiles are easy to collide with the port of the material conveying groove 13.
The design advantage of the clamping piece 3 is as follows:
firstly, the abutting block 33 is designed to be hexagonal, the abutting block 33 can rotate around the outer surface of the polish rod 32, when the aluminum profile slides through the upper surface of the storage plate 14, the aluminum profile contacts the outer surface of the abutting block 33, the abutting block 33 can rotate, the sliding direction of the aluminum profile is corrected, and the phenomenon that the aluminum profile impacts the port of the material conveying groove 13 due to overlarge offset in the sliding process of the aluminum profile is avoided.
Secondly, replace current electric putter or pneumatic putter with supporting tight piece 33 (electric putter or pneumatic putter need independent design, and do not possess correction aluminium alloy slip direction function), in aluminium alloy tip supporting tightly behind electric baffle, the inside hydraulic telescoping rod of elevator group 16 drives lifter plate 21 upward movement, drive pinion rack 17 upward movement, because worm 35 is through the cover tooth cover 36 of being established in its outside and the meshing of pinion rack 17 surface is connected, so when lifter plate 21 upward movement, drive worm 35 through tooth cover 36 and rotate around workstation 11 inside, worm 35 drives worm wheel 34 and rotates, drive interior bull stick 31 and rotate around placing thing board 14 inside, because interior bull stick 31 top and polished rod 32 lower surface non-center installation, in the polished rod 32 rotation process, can drive supporting tight piece 33 to one side of aluminium alloy surface motion, supporting tight piece 33 extrudees aluminium alloy surface, make it closely laminate on the inner wall of material conveying groove 13 and the guide block 142 surface (replace traditional electric putter or pneumatic putter, realize the tight to the clamp of aluminium alloy surface with the help of lifter plate 21 upward movement state, the time of synchronous realization is to the independent setting up electric putter, or the tight piece 33 of supporting tight piece 33, and can not rotate with the same time rotate the smooth rod 33 to the surface of polished rod 32, and the surface is the realization is rotated clockwise to the surface is rotated to the smooth rod 33, and is rotated to the surface is rotated to the smooth rod 32 is rotated to the surface is fixed to the surface is rotated to the side of the smooth rod 33.
Thirdly, the strength of the abutting block 33 is adjustable, and as the materials of the aluminum profiles are different, the clamping strength born by different aluminum profiles is different.
