[0062] An operation and control method applied to machine tool molds, including:

[0063] S1: Stamping model clamping:

[0064] When the stamping model 1 needs to be clamped, the controller controls the oil cylinder 6a to move, the oil cylinder 6a drives the pull plate 6b to move downward, and then the pull plate 6b drives the adjustment mechanism 7 and the second hinge seat 5d to move downward. In turn, the second hinge base 5d and the first hinge base 4d pull down the second hinge rod 5c and the first hinge rod 4c, so that the second hinge rod 5c drives the two second connecting plates 5b, the second pressure plate 5a and the first hinge rod 5c. The two rubber pads 5e move closer to each other, so that the two second rubber pads 5e clamp the two sides of the stamping model 1, and the first hinge rod 4c is downward, so that the first hinge rod 4c drives the two second A connecting plate 4b, a first clamping plate 4a and a first rubber pad 4e move closer to each other, so that the two first rubber pads 4e clamp the other two sides of the stamping model 1;

[0065] Wherein, in the process of pulling down the cylinder 6a, if the shape of the stamping model 1 is not square, the adjustment mechanism 7 is adjusted so that the first clamp 4 and the second clamp 5 can clamp the stamping model 1;

[0066] S2: Clamping adjustment:

[0067] When the cylinder 6a is pulled downwards, because the shape of the stamping model 1 is not square, the two first clamps 4 or the two second clamps 5 will clamp the two sides of the stamping model 1. After the two second clamps 5 first clamp both sides of the stamping model 1, the worker rotates the first turntable 7e forward, so that the first turntable 7e drives the shaft 7d to rotate forward, so that the two screws 7a and the two The first hinged base 4d is engaged, so that the two first hinged bases 4d move closer to each other, and then clamp the other two sides on the peripheral wall of the stamping model 1. When the two first clamps 4 first clamp After stamping the two sides of the model 1, the worker reverses the first turntable 7e, which will cause the first turntable 7e to drive the shaft 7d to reverse, so that the two screw rods 7a are engaged with the two first hinge seats 4d respectively, and the two The first hinge seat 4d moves away from each other, and then moves downward through the oil cylinder 6a, so that the second clamp 5 clamps the other two sides of the peripheral wall of the stamping model 1;

[0068] S3: height adjustment of the stamping model;

[0069] After clamping, the controller controls the press to press down, and then presses down on the top of the stamping model 1, and then the worker rotates the third turntable 3k, so that the third turntable 3k drives the shaft 3b to rotate, so that the shaft 3b drives The second bevel gear 3f rotates, so that the second bevel gear 3f meshes with the first bevel gear 3e, so that the second bevel gear 3f drives the threaded rod 3d to rotate, and the threaded rod 3d drives the threaded sleeve 3c to rotate. In turn, the threaded sleeve 3c drives the upper receiving box 2c to move upward, thereby adjusting the punching contact distance of the punch to the punching model 1;

[0070] S4: Increase the pressure adjustment;

[0071] When the total punching force needs to be increased, the height adjustment mechanism 9f is adjusted by the worker to make the upper rubber pad 9a move upward, so that the punch presses the stamping model 1 downward, and the support box 8 compresses the damping spring 2a. When the bottom surface of the support box 8 touches the top of the upper rubber pad 9a, the support box 8 compresses the upper rubber pad 9a and the lower rubber pad 9b, thereby increasing the resistance to the support box 8. , So that both the upper rubber pad 9a and the lower rubber pad 9b are compressed. In this process, the supporting force for the stamping model 1 is increased, thereby increasing the punching force of the punch on the plate on the stamping model 1. When the sum of the punching forces needs to be reduced, The height adjustment mechanism 9f is adjusted by the worker, so that the upper rubber pad 9a moves downwards, thereby reducing the compressed thickness of the upper rubber pad 9a and the lower rubber pad 9b, thereby reducing the total pressing force.

[0072] Then the controller starts the punching machine to work, so that the punching machine punches the plate on the punching model 1, and reduces the vibration of the equipment through the shock-absorbing spring 2a.
