摘要： A method of manufacturing a metal component includes performing a test stamping process on a test sheet metal blank, generating a strain map of the test sheet metal blank for the test stamping process, generating a lubrication program based on the strain map, applying lubrication to the sheet metal according to the lubrication program, and stamping the sheet metal to form the metal component. The lubrication program is configured to control a lubrication system to apply lubrication to sheet metal in a non-uniform distribution across the sheet metal. The non-uniform distribution correlates to the strain map.

摘要： Provided is a control device for a plate feeding device with which the amount of a plate transported to a processing device by the plate feeding device can be measured with high accuracy. This control device for a plate feeding device includes: a control unit that controls the rotation of a first roll and a second roll of the plate feeding device; a transmission unit that transmits an electromagnetic wave toward a plate; and a transmission unit that transmits the electromagnetic wave toward the plate, wherein the control unit measures the transport speed of the plate during a predetermined period on the basis of the frequency of the electromagnetic wave received by the reception unit, and measures the transport amount of the plate on the basis of the transport speed.

摘要： A rotary stamper includes an upper die plate assembly, a lower die plate assembly, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway while moving the lower die plate along a linear horizontal pathway. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods that extend from the lower die plate assembly up through the upper die plate. In operation, the lower die plate matches the horizontal movements of the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper die plate moves towards and away from the lower die plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.

摘要： A press forming system includes a press working unit, a material supply device, a detection device, and a control device. The press working unit includes a slide that moves in accordance with an operation pattern in which the slide passes through an advance position where press forming is formed from a withdrawal position, and returns to the withdrawal position. The material supply device starts a supply operation at a synchronous timing before the slide returns from the advance position to the withdrawal position. The control device performs a control for stopping the slide before the slide reaches the withdrawal position from the advance position in a case where the suppliable state of the forming material is not detected within a predetermined determination period by the detection device.

摘要： An automatic production equipment includes a strip-material feeding device set, a continual stamping die set and a rivet providing mechanism. The strip-material feeding device set feeds a strip material. The continual stamping die set includes a upper stamping die group and a lower stamping die group. The lower stamping die group includes a lower die plate, a strip receiving groove formed on the lower die plate for receiving the strip material, a sliding block slidable on the strip receiving groove, and a guide groove formed on the sliding block to connect to the strip receiving groove. The upper stamping die group includes an upper clamping plate, a pushing lever and a riveting punch. The pushing lever and the riveting punch are located on the upper clamping plate. The rivet providing mechanism is connected to the sliding block, and feeds rivets into the guide groove in order.
