According to the cutting machine provided by the invention, the cutting track of the blade formed by the upper blade 15 and the lower blade 50 corresponds to the shape of a cut piece to be cut; the cost of the traditional guillotine in the die manufacturing is reduced; the cutting machine designed by the invention is suitable for producing clothes with small batch and large style change.

The upper blade 15 and the lower blade 50 are made of elastic materials, blade tracks similar to the shapes of the cut pieces can be formed by fixing the first blade mounting units 5 which are matched with the shapes of the cut pieces, and the bending angles of the cut piece tracks are smaller than the minimum bending angles of the blades because the blade tracks are bent by the elastic blades. The blade bending paths in the drawings of the present invention are merely schematic.

The specific working process is as follows: when the cutting machine designed by the invention is used, before the cutting machine is used, the serial numbers of a group of first blade mounting units 5 which are most fit with the shapes of the cut pieces can be simulated by a computer according to the actual shapes of the cut pieces by the upper die 3 and the lower die 4, the corresponding first blade mounting units 5 are adjusted according to the serial numbers, so that the upper blade 15 and the lower blade 50 are mounted on the upper die 3 and the lower die 4, and the blade cutting track formed by the upper blade 15 and the lower blade 50 corresponds to the shapes of the cut pieces to be cut.

When the blade mounting unit is mounted, the magnetic suction cups 36 and the magnetic attraction blocks 59 at the corresponding positions are electrified according to the simulated serial numbers of the computer to enable the blade mounting unit to have magnetism, the magnetic suction cups 36 and the magnetic attraction blocks 59 in the second blade mounting unit 51 are electrified to enable the blade mounting unit to have magnetism, and then the upper ends of the plurality of blade mounting bodies 16 are respectively inserted into the circular mounting grooves 31 at the lower ends of the mounting shells 10 at the corresponding positions. In the inserting process, after the blade mounting body 16 is contacted with the mounting post 12, the blade mounting body 16 can extrude the mounting post 12, so that the mounting post 12 moves upwards, the mounting post 12 moves upwards to drive the limiting block 13 to move upwards through the connecting plate 44, the limiting block 13 moves upwards to stretch the second return spring 11, meanwhile, the limiting block 13 moves upwards to enable the triangular inclined plane on the limiting block to be gradually matched with the two clamping blocks 14, and the two clamping blocks 14 pull the two clamping blocks 14 to gradually move towards the inner side of the mounting shell 10 under the action of the corresponding third return springs 24; when the two fixture blocks 14 completely move into the mounting shell 10, the two fixture blocks 14 are also separated from the corresponding clamping grooves 21 on the second template 9, the second soft magnet 37 on the mounting column 12 is just in contact with the magnetic sucker 36 at the lower end of the limiting disc 26, the second soft magnet 37 is sucked by the magnetic sucker 36, meanwhile, the third soft magnet 38 which is in contact with the mounting column 12 and is mounted on the blade mounting body 16 is sucked, and at the moment, the mounting column 12, the limiting disc 26 and the blade mounting body 16 are sucked and fixed; after the two clamping blocks 14 are separated from the clamping grooves 21 on the second template 9, the upward-moving blade mounting body 16 pushes the mounting shell 10 to move upward under the action of the limiting disc 26 and the mounting column 12, so that the first soft magnet 23 mounted at the upper end of the mounting shell 10 and the magnetic attraction block 59 mounted at the lower side of the second template 9 are contacted and adsorbed, and in the process of moving upward of the mounting shell 10, the mounting shell 10 drives the guide rod 22 to move upward, and the guide rod 22 moves upward to pull the corresponding fourth return spring 25. After the blade mounting body 16 is mounted, the blade is mounted. In this process, the attractive force of the magnetic attraction block 59 to the first soft magnet 23 is greater than the restoring force of the fourth return spring 25, i.e., the fourth return spring 25 cannot separate the magnetic attraction block 59 from the first soft magnet 23.

When the upper blade 15 and the lower blade 50 are installed, the blades are bent forcibly to adapt to the position of a first blade installation unit 5 to be installed, the U-shaped grooves on the blades are inserted into corresponding fixing columns 41 after the U-shaped grooves correspond to each other, the blade installation body 16 is rotated firstly in the inserting process, the direction is adjusted, the upper ends of the U-shaped grooves and the inclined surfaces of the two limiting fixture blocks 45 can be in direct contact, after the contact, the upper ends of the U-shaped grooves can extrude the two limiting fixture blocks 45, so that the two limiting fixture blocks 45 move inwards, the plate spring 43 is compressed, after the limiting clamping grooves 60 formed in the U-shaped grooves are matched with the limiting fixture blocks 45, the two limiting fixture blocks 45 extend out again under the action of the plate spring 43 and are clamped in the limiting clamping grooves 60, and the blades are clamped; simultaneously inserting the two ends of the upper and lower blades 50 into the second blade mounting units 51, finally adjusting the positions of the two second blade mounting units 51, and adjusting the angle between the two ends of the upper blade 15 and the upper cutting blade, so that the end surface of the upper blade 15 can be tightly attached to the upper cutting blade 61, and fixing the positions of the two second blade units by tightening the rivets 53; and after the blade is installed, the hydraulic push rod 2 is controlled to drive the upper die-cutting die 3 to move downwards.

During the blanking, since the upper and lower blades 50 are positioned more inward with respect to the first blade mounting units 5 around them without being mounted, so that when the upper die cutting die 3 and the lower die cutting die 4 are brought into contact, the first blade mounting unit 5 to which no blade is mounted, after the corresponding mounting shells 10 are firstly contacted with each other, the pressure is applied to the garment pieces to ensure that the garment pieces cannot move in the cutting process, then the hydraulic push rod 2 is continuously driven to move downwards to push the first template 8 of the upper punching die 3 to move downwards, because the first blade mounting unit 5 provided with the blades is limited with the second template 9, as the first die plate 8 of the upper die cutting die 3 moves downward, the second die plate 9 of the upper die cutting die 3 presses the first die plate 8 of the lower die cutting die 4 by the first return spring 6, and the first die plate 8 of the lower die cutting die 4 moves downward relative to the second die plate 9 while the second return spring 11 of the lower die cutting die 4 is compressed. In this process, the upper blade 15 fixed to the blade mounting body 16 moves downward along with the first pattern plate 8 of the upper die 3, the lower blade 50 fixed to the blade mounting body 16 and the first pattern plate 8 of the lower die 4 are fixed, and the upper blade 15 and the lower blade 50 are staggered with each other to die cut the garment as the first pattern plate 8 of the lower die 4 moves downward.

The upper and lower blades 50 of the present invention do not have a closed path after bending and punching according to the shape of the cut pieces, and the cut pieces that are not cut by the upper and lower blades 50 are cut by the upper and lower cutting blades in the areas that are not cut by the upper and

lower blades

15 and 50.

When the blade track needs to be adjusted according to a new garment piece or the blade needs to be detached, because the detaching process of the upper blade 15 and the lower blade 50 is the same, for example, when the upper blade 15 is detached, the energized magnetic suction cup 36 and the magnetic suction block 59 are powered off, at the same time, the magnetic suction cup 36 and the magnetic suction block 59 lose magnetic force, at the same time, under the action of the fourth return spring 25, the mounting shell 10 is reset, at the same time, the limit block 13 is reset under the action of the second return spring 11, the limit block 13 resets and extrudes the two fixture blocks 14 to reset the two fixture blocks 14 to extend out of the mounting shell 10, after the two fixture blocks 14 completely extend out of the containment shell, the inclined planes at the lower sides of the two fixture blocks 14 are reset along with the mounting shell 10, one end of the inclined plane of the fixture block 14 is in extrusion fit with the upper end of the inner side surface of the third hole 20 at the upper side of the, the fixture block 14 extends into the corresponding clamping groove 21 formed in the second template 9, and after the fixture block 14 extends into the clamping groove 21, the depth of the lower end of the clamping groove 21 is greater than the length of the inclined surface of the fixture block 14, that is, the inclined surface of the fixture block 14 completely extends into the clamping groove 21, the inclined surface of the fixture block 14 cannot be in extrusion fit with the lower end surface of the clamping groove 21, the clamping groove 21 prevents the fixture block 14 from moving downwards, and the downward movement of the mounting shell 10 is prevented; during the return of the two latch blocks 14, the corresponding third return springs 24 are stretched. In addition, under the action of the second return spring 11, the mounting post 12 moves downwards along with the limiting block 13 to return, and the magnetic force of the magnetic sucker 36 disappears, so that the blade mounting body 16 and the mounting post 12 lose the magnetic force, but the blade cannot automatically fall off due to the restoring force after the blade is bent, and at the moment, the blade is taken down under the assistance of manpower.
