Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1 and 2, the present invention provides a punching shear module including a tool mounting device 6, a rotation driving member 8 for driving the tool mounting device 6 to rotate, and a lifting driving member 7 for driving the tool mounting device 6 to lift. The cutter 3 is detachably connected with the cutter mounting device 6, so that an operator can conveniently replace the cutter 3. The rotation driving piece 8 can be a stepping motor with high angle regulation precision, and the lifting driving piece 7 can be a linear motor, a cylinder or hydraulic cylinder and other equipment capable of outputting linear displacement.

The rotary driving member 8, the lifting driving member 7 and the tool mounting device 6 are connected in various modes, for example, the rotary driving member 8 and the tool mounting device 6 can be connected first, and then the lifting driving member 7 drives the rotary driving member 8 and the tool mounting device 6 to move up and down; it is also possible to connect the lifting drive 7 to the tool mounting device 6 first and then to drive the lifting drive 7 by the rotary drive 8 for a rotary movement together with the tool mounting device 6.

In one embodiment of the present invention, the tool mounting device 6 further comprises a housing 100, a guide sleeve 94 rotatably provided in the housing 100, and a connecting shaft 95 in driving connection with a flat key provided on an inner wall of the guide sleeve 94, and is detachably mounted at a lower end of the connecting shaft 95. The rotation driving member 8 drives the guide sleeve 94 to rotate, and the lifting driving member 7 drives the connecting shaft 95 to lift. The output shaft 81 of the rotary driving member 8 is provided with a driving wheel 91, the outer side of the guide sleeve 94 is provided with a driven wheel 93, and the driving wheel 91 is in transmission connection with the driven wheel 93 through a synchronous belt 92. The output end of the lifting driving member 7 is connected to the upper end of the connecting shaft 95.

When the rotary driving piece 8 works, the output shaft 81 drives the guide sleeve 94 to rotate, the guide sleeve 94 drives the connecting shaft 95 to synchronously rotate through the flat key, and then the cutter mounting device 6 and the cutter 3 positioned at the lower end of the connecting shaft 95 are driven to rotate. When the lifting driving piece 7 works, the output end of the lifting driving piece drives the connecting shaft 95 to do lifting motion, and the connecting shaft 95 slides up and down relative to the guide sleeve 94 to drive the cutter mounting device 6 to lift.

As shown in fig. 2 and 3, the present invention preferably employs a cylinder as the elevation driving member 7, and the lower end of the piston rod 71 of the cylinder is fixedly connected coaxially with the upper end of the connecting shaft 95 through a coaxial connector 96. Further, a fixed sleeve 72 is fixed at the top of the cylinder, a rotating sleeve 73 is connected to the inner side of the fixed sleeve 72 in a threaded manner, the upper end of the piston rod 71 penetrates through the rotating sleeve 73 to be connected with a limiting block 731 is arranged at the bottom of the rotating sleeve 73, and the limiting block 731 can bear downward impact force applied by the limiting sleeve 711 and limit the limiting sleeve 711.

When in use, the rotating sleeve 73 is manually rotated, so that the rotating sleeve 73 is lifted and lowered in the fixed sleeve 72, and the height of the limiting block 731 is changed. Because of the working property of the air cylinder, the highest point where the piston rod 71 is located is unchanged, the height of the limiting block 731 is increased, so that the lowest point which can be reached by the piston rod 71 is increased, and the descending distance of the piston rod 71 is reduced; the lowering of the height of the stopper 731 lowers the lowest point that the piston rod 71 can reach, and the lowering distance of the piston rod 71 increases. According to the invention, the cutting edge depth formed in the cloth by the cutter 3 is changed by adjusting the descending distance of the piston rod 71, so that the processing requirements of different kinds and thicknesses of cloth are met.

As shown in fig. 4 to 6, the tool mounting device 6 includes a tool mounting shaft 1, a sleeve 2 fitted around the tool mounting shaft 1, a press block 4, and a first fastener 51, the tool mounting shaft 1 including a mounting portion 11 for accommodating the tool 3, the first fastener 51 penetrating through the sleeve 2 to press the press block 4, and fixing the tool 3 between the press block 4 and the mounting portion 11. The knife 3 is in particular a straight knife, V-knife or a knife with other knife surface shapes.

Because the cutter 3 is detachably connected with the cutter mounting shaft 1, when the cutter 3 needs to be replaced or maintained, the cutter 3 can be taken out of the mounting part 11 only by sequentially removing the first fastener 51 and the pressing block 4, and the operation is very simple.

In one embodiment of the present invention, the first fastener 51 includes a first head 511 and a first body 512 connected to each other, the first head 511 having an outer diameter smaller than that of the first body 512; the shaft sleeve 2 is provided with a first opening 21, the first main body 512 is in threaded connection with the first opening 21, and the first head 511 is matched with a clamping groove formed on the pressing block 4. By screwing the first body 512 into the first opening 21, the first head 511 gradually enters the clamping groove on the press block 4 until the junction of the first head 511 and the first body 512 is limited by the press block 4, and the first fastener 51 is in place, and continuously provides a pressing force to the press block 4 toward the cutter 3. The pressing block 4 and the cutter 3 are made of metal materials, and a first magnetic attraction piece 13 for attracting the cutter 3 and a second magnetic attraction piece 14 for attracting the pressing block 4 are further arranged in the mounting part 11. The first magnetic attraction member 13 and the second magnetic attraction member 14 are specifically magnets. After the operator removes the first fastening piece 51, the pressing block 4 is still absorbed in the mounting part 11 by the second magnetic attraction piece 14, and the pressing block cannot automatically fall off from the mounting part 11 due to the fact that the jacking force provided by the first fastening piece 51 is lost; then, after the operator manually removes the pressing block 4, the cutter 3 is still absorbed in the mounting portion 11 by the first magnetic attraction piece 13, and the cutter is not automatically separated from the mounting portion 11 due to the disappearance of the pushing force provided by the pressing block 4. The arrangement greatly enhances the use safety of the device, and can avoid operation risks and part damage caused by falling off of the pressing block 4 and the cutter 3.

In order to ensure the connection and fastening between the shaft sleeve 2 and the tool mounting shaft 1, a second opening 22 extending along the radial direction of the shaft sleeve 2 is further formed in the shaft sleeve 2, a connection hole 15 extending along the radial direction of the mounting portion 11 is formed in the mounting portion 11, and the connection hole 15 and the second opening 22 are connected through a second fastening member 52.

Further, the aperture of the connection hole 15 is larger than that of the second opening 22, and the second fastener 52 includes a second head 521 and a second body 522 connected to each other, the second head 521 is engaged with the second opening 22, and the second body 522 is screwed with the connection hole 15. In the initial state, the second fastener 52 is completely located in the connection hole 15; when it is desired to connect the sleeve 2 and the tool mounting shaft 1, the second fastener 52 can be rotated through the second opening 22 on one side so that the second head 521 gradually enters the second opening 22 on the other side until the junction of the second head 521 and the second body 522 is restrained by the inner wall of the second opening 22, and the second fastener 52 is in place. This arrangement is easy to handle and prevents the second fastener 52 from being lost.

Further, the tool mounting shaft 1 further includes a connecting portion 12 coaxially connected with the mounting portion 11, and the connecting portion 12 is detachably connected with the lower end of the connecting shaft 95. In order to prevent the shaft sleeve 2 and the tool connecting shaft 1 from being released due to the impact force of the lifting drive member 7 when the tool mounting device 6 is driven to lift, it is preferable that a limit step 111 is further provided at the bottom of the mounting portion 11, and the bottom of the shaft sleeve 2 abuts against the limit step 111. The limit step 111 can provide a supporting force to the sleeve 2 to buffer downward impact.

The invention also provides a cutting bed which comprises the punching and shearing module.

The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
