Description

Technical Field

[0001] The invention relates to the technical field of sheet metal stamping, and in particular to a sheet metal forming flexible manufacturing multi-process collaborative production line. Background Art

[0002] Stamping is a forming processing method that relies on presses and dies to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces of desired shape and size. Stamping and forging belong to plastic processing, collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the steel in the world is plate material, most of which are made into finished products by stamping. The car body, chassis, fuel tank, radiator fins, boiler drum, container shell, motor and electrical core silicon steel sheets are all processed by stamping. There are also a large number of stamped parts in products such as instruments and meters, household appliances, bicycles, hand dryers, office machinery, and daily utensils.

[0003] A Chinese patent with announcement number CN114632857B discloses an automated production line for sheet metal stamping, including a work box, a feeding conveyor is provided at the left end of the interior of the work box, a stamping device is provided in the middle of the interior of the work box, a discharging conveyor is provided at the right end of the interior of the work box, and also includes guide detection devices arranged at both ends of the surface of the feeding conveyor, and an inclination detection device arranged on the left side of the internal top, and a clamping device slidably connected to both ends of the interior of the work box, and an ultrasonic detection device arranged in the middle of the rear end of the inner wall of the work box. The present invention achieves the effect of reducing the movement trajectory of the robot arm, increasing work efficiency, and preventing the robot arm from offsetting when placing the sheet metal, resulting in damage to the sheet metal stamping, and can also achieve the effect of being able to perform quality inspection on the sheet metal after stamping, preventing problems in the sheet metal stamping from being manually identified and processed, reducing labor, and increasing the accuracy of detection.

[0004] However, the above technical solution has the following shortcomings: the ultrasonic detection device detects the sheet metal from the top and can only detect relatively flat sheet metal parts. It is difficult to effectively detect three-dimensional parts with relatively close length, width and height dimensions, and cannot meet diverse production needs. Summary of the invention

[0005] The purpose of the present invention is to address the problems existing in the background technology and to propose a sheet metal forming flexible manufacturing multi-process collaborative production line.

[0014] A material unloading unit is arranged on one side of the punching unit to deliver the processed materials out of the production line;

[0015] There are multiple robotic arms, which are used for transferring and unloading materials between various processing units.

When a detection head detects a sheet metal part, the detection head first rotates around the sheet metal part for one circle to detect the circumference of the sheet metal part. Then, the detection head is driven by the adjusting mechanism to move to the top of the sheet metal part to detect the top of the sheet metal part, thereby achieving more accurate detection of the sheet metal part. This effectively meets diversified production needs and is beneficial to improving the accuracy and quality of sheet metal processing. BRIEF DESCRIPTION OF THE DRAWINGS
