[0048] The technological method of ingot trimming is as follows:

[0049] Standby state: First, check that all equipment is safe and reliable and meets the requirements of safe production, and the conveyor has been started and is running normally; Then determine that all components of the centering and trimming machine are in normal working condition, and the centering claws are in the separated and relaxed state; Then determine that all components of the ingot positioning, clamping and feeding machine are in normal working condition, the positioning fixture assembly is at the positioning station, and the whole machine is in the positioning state; Then determine that all components of the ingot long side trimming machine are in normal working condition, and the tool device is at the right starting position;

[0050] Method Step 1. Ingot Input Process: The conveyor delivers the ingot to the positioning station;

[0051] Method Step 2. Y-axis Positioning Process: The oscillating cylinder drives the gear to rotate. When the gear rotates forward, the gear drives the rack to move linearly. The forward rotation of the gear drives two racks to move towards each other. The rack drives the centering claws to move towards each other along the guide shaft, centering and clamping, thus achieving the Y-axis positioning of the ingot;

[0056] Method Step 7. Clamping Claw Return to Horizontal Position Process: After the long-side trimming is completed, the piston rod of the clamping cylinder retracts. The Y-shaped joint of the clamping cylinder fixedly connected to the piston rod drives the entire clamping claw component to rotate downward around the axis of the clamping claw rotating shaft to the horizontal position through the clamping claw connecting rod;

[0057] Method Step 8. Positioning Claw Return to Horizontal Position Process: The piston rod of the positioning cylinder retracts. The Y-shaped joint of the positioning cylinder fixedly connected to the piston rod drives the entire positioning claw component to rotate downward around the axis of the positioning claw rotating shaft to the horizontal position through the positioning claw connecting rod;

[0058] Method Step 9. Ingot Output Process: The conveyor transports the ingot forward and away from the ingot trimming station, and all the long-side trimming work of this ingot is completed;

[0059] Method Step 10. Slide Table II Reset Process: The servo motor II of the lead screw slide table assembly II drives the lead screw II to rotate reversely. The lead screw II drives the slide table II to move linearly backward. The slide table II drives the fixedly connected positioning fixture assembly to return to the initial position of the positioning station;

[0060] Repeat Method Steps 1 to 10 to complete the next cycle of the ingot trimming machine.

[0061] The overall working process of the ingot trimming machine is: Ingot input - Positioning - Clamping - Feeding (while trimming short sides) - Trimming long sides - Returning to standby.

[0062] Description of the short side trimming process: The servo motor II of the lead screw slide assembly II of the ingot positioning clamping and feeding machine drives the lead screw II to rotate forward. The lead screw II drives the slide II to move linearly forward. The slide II drives the positioning fixture assembly fixedly connected thereto and the ingot together to the long side trimming station. During this feeding process, the ingot passes through the centering fixture frame. On the side of the centering fixture frame close to the trimming station longitudinally, there are a right scraper and a left scraper, and the short side trimming of the ingot is completed simultaneously.

[0063] Description of the long side trimming process: The servo motor I of the lead screw slide assembly I accurately controls the stroke of the scraper. There are 4 scrapers in two groups A and B on the scraper holder. When the scraper moves from left to right, the two scrapers in group A at the left end simultaneously trim the front and back two long sides of ingot I. When the scraper moves from right to left, the two scrapers in group B at the right end simultaneously trim the front and back two long sides of ingot II.
