The positioning rods 5 are inserted into the positioning holes, and the bottom ends of the positioning rods 5 are located below the stamping plate 7. When the grabbing plate 2 pushes the stamping plate 7 down, the lifting rod 901 can be pushed down by the positioning rods 5.

[0030] See also Figure 4-6 The demoulding device 9 includes a lifting rod 901, which is plugged into the top of the base 3. A connecting plate 902 is fixedly installed at the bottom end of the lifting rod 901. A sliding rod 903 is fixedly installed on the side of the connecting plate 902 away from the center of the base 3.

A reset spring 913 is fixedly installed between the push plate 912 and the side plate 909.

[0031] See also Figure 6 The other end of the connecting rope 907 is fixedly installed on the side of the push block 911 close to the side plate 909. The connecting rope 907 passes through the side plate 909. The end at which the two extrusion rods 906 are connected to each other is lower than the end at which the extrusion rod 906 is connected to the rotating plate 905. When the extrusion rod 906 is pushed by the rotating plate 905, the end at which the two extrusion rods 906 are connected to each other will move away from the end at which the rotating plate 905 is connected to the extrusion rod 906, thereby pulling the connecting rope 907, and pulling the push block 911 toward the side plate 909 through the connecting rope 907.

[0032] See also Figure 1-5 A punching port is provided on the top of the base 3, and the punching port corresponds to the punching head 8. A card slot is provided on both sides of the punching head 8. The push block 911 is located directly below the left and right ends of the punching port. When the punching head 8 is pushed down, the punching head 8 is inserted into the punching port to complete the punching. The card slot is a right-angle trapezoid. The side of the card slot close to the punching plate 7 is an inclined surface. The inclination direction is that the side close to the center of the punching head 8 is lower than the side away from the center of the punching head 8. The top of the push block 911 is an inclined surface. The inclined direction The side away from the center of the base 3 is higher than the side close to the center of the base 3. When the punch head 8 is inserted into the punching port, the bottom end of the punch head 8 fits with the inclined surface of the push block 911, thereby pushing the push block 911 toward the side plate 909. As the punch head 8 continues to descend, when the push block 911 and the slot are in the same horizontal plane, under the action of the reset spring 913, the push block 911 is pushed into the slot, and the push block 911 is embedded in the slot, thereby blocking the punch head 8 to prevent reset.

[0033] See also Figure 4-5 The demoulding device 9 is divided into two groups, which are installed symmetrically along the vertical center line of the base 3. Each group of demoulding devices 9 has two lifting rods 901. The four lifting rods 901 are all inserted into the base 3 and correspond to the positions of the positioning rods 5. When the positioning rods 5 descend, the lifting rods 901 can be pushed down.

An anti-falling plate is fixedly installed on the side of the slide rod 903 away from the lifting rod 901. When the lifting rod 901 is raised or lowered, the rotation of the rotating plate 905 can be driven by the slide rod 903.

[0036] Working principle: When punching starts, the base 3 is prevented from being on the surface of the punching machine, and the grabbing clamp 4 fixes the punching plate 7 through the clamping plate 6. At the same time, the positioning rod 5 is inserted into the punching plate 7, and the punched plate is placed above the lifting rod 901. As the punching plate 7 descends, the positioning rod 5 pushes the lifting rod 901 to descend. Since the lifting rod 901 is connected to the rotating plate 905 through the sliding rod 903, when the rotating plate 905 is driven to rotate, the compression spring 908 is squeezed, the squeezing plate is driven to move, and the end of the squeezing rod 906 connected to each other descends, thereby pulling the push block 911 to move toward the side plate 909 through the connecting rope 907, and the main punching head 8 will not be stuck, avoiding the main punching head 8. The punching head 8 is stuck in the punching port for punching;

[0037] After the stamping is completed, the stamping plate 7 rises, the punch head 8 is separated from the stamping port, the positioning rod 5 no longer presses the lifting rod 901, and the compression spring 908 begins to reset, pushing the lifting rod 901 upward in the reverse direction, and the lifting rod 901 pushes out the plate adhered to the base 3, completing demoulding;

[0038] When the stamping die needs to be replaced after the stamping is completed, the die needs to be installed on the turret, the lifting rod 901 is inserted into the socket, the stamping plate 7 is lowered under the drive of the grabbing clamp 4, the punching head 8 is inserted into the punching port and the socket, the lifting rod 901 is pushed down by the positioning rod 5, the push block 911 is pressed to the left and right sides, the grabbing clamp 4 releases the clamping plate 6, the positioning rod 5 is disengaged from the stamping plate 7, the lifting rod 901 is no longer subjected to downward pressure, the compression spring 908 is reset, pushing the lifting rod 901 to rise, and the connecting rope 907 no longer pulls the push block 911. The push block 911 is reset under the action of the reset spring 913, and is inserted into the slots on the left and right sides of the punching head 8, locking the punching head 8, thereby completing the purpose of fixing the base 3 and the stamping plate 7 on the turret, and at the same time, it can also avoid the problem of spring life being damaged due to long-term compression.

[0039] In summary, in the CNC turret punch press with convenient demoulding, during stamping, the punched sheet is located above the lifting rod 901, the positioning rod 5 is inserted into the punching plate 7, the grabbing plate 2 drives the punching plate 7 to descend, the positioning rod 5 descends to push the sheet and the lifting rod 901 to descend, the lifting rod 901 drives the rotating plate 905 to rotate, the compression spring 908 is compressed, and after the stamping is completed, the positioning rod 5 rises, the lifting rod 901 is no longer squeezed, the compression spring 908 pushes the rotating plate 905 to rotate in the opposite direction, thereby pushing the lifting rod 901 to rise, and the sheet is ejected from the upper surface of the base 3, completing the effect of auxiliary demoulding; by When the base plate is installed on the turret, the lifting rod 901 corresponds to the jack, the punch head 8 corresponds to the socket, the punch head 8 is inserted into the punching port, and the lifting rod 901 is pressed downward by the positioning rod 5.
