摘要： A feeding assembly is for feeding material to a press system. The press system includes a shell press having a die set structured to form the material into a plurality of shells. The feeding assembly includes a support element, a feed roll including an integral shaft, a drive assembly driving the feed roll and including a motor and a drive shaft, the drive shaft, and a pinch roll cooperating with the feed roll to receive and move material therebetween. The longitudinal axis of the integral feed roll shaft is laterally offset with respect to the longitudinal axis of the motor drive shaft.

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 plate-like material feeding device configured to sandwich a plate-like material between a lower roll rotatably supported on a device main body and an upper roll which is rotatable and arranged to face the lower roll in parallel thereto, so as to convey the plate-like material. The plate-like material feeding device includes: a lower gear integrally provided on a rotation shaft of the lower roll; an intermediate gear which is meshed with the lower gear, and is integrally provided on a rotation shaft of the upper roll; an upper gear meshed with the intermediate gear; a lower-roll drive motor which is coupled to the rotation shaft of the lower roll so as to drive the rotation shaft of the lower roll to rotate; and an upper-roll drive motor configured to drive the upper gear to rotate.

摘要： A press system and a control method of the press system that can automatically set a timing for coordinating a press machine and a feeding device. A leveler feeder includes feed rolls that convey a coil material to the press machine in a closed state in which the coil material is clamped, and are brought into an open state in which the coil material is released when stamping by the press machine is started. The press machine includes a sensor for detecting a load F at a time of the stamping, a pilot pin that is inserted into a hole pierced in the coil material for positioning at a time of the stamping, and a controller for controlling the leveler feeder and the press machine so as to perform the stamping in coordination with each other. The controller determines a release start timing Tos (a position Ps+L) at which the feed rolls are switched from the closed state to the open state based on a result of detecting by the sensor as well as a length L of the pilot pin.

摘要： A tab stock feeder assembly for a press includes a plurality of support elements, a plurality of rotating elements, and a number of operative elements. Each rotating element is rotatably coupled to an associated support element. Each operative element coupled to at least one of the support element or one of the rotating element and wherein each the operative element is structured to be engaged by a rotating element. The tab stock feeder assembly further includes a wear reduction assembly including a plurality of wear reducing elements. A plurality of support elements have at least one wear reduction assembly wear reducing element disposed between a rotating element and the associated support element.

摘要： In a roller-style feed mechanism, a feed roll is opened and closed for the purpose of pilot release using a direct-coupled servo motor as opposed to pneumatic or hydraulic cylinders. The electronically controlled servo motor drives a rotating shaft with eccentric cams that interact with cam followers causing the feed rollers separate for pilot release. The cam followers produce a force sufficient to overcome nip pressure when separating the feed rollers during pilot release. The electronically controlled servo motor is preferably operative to sense the point where the cams contact the cam followers after the upper feed roller is closed on the feed material, and automatically sense resistance to determine where the upper roll begins to lift so as to compensate for different material thicknesses.

摘要： A roll feeder is usable to convey a hoop material to a pressing machine. The roll feeder includes a paired first roll and second roll configured to be disposed so as to clamp the hoop material and feed the hoop material along a conveyance direction, a motor configured to drive at least one of the first roll and the second roll, and a controller configured to control drive of the motor. The controller includes a process drive instruction component configured to drive the motor so as to feed the hoop material to a pressing machine side in between one press working and next press working, and a working drive instruction component configured to drive the motor so as to feed the hoop material to the pressing machine side during press working.

摘要： A sheet material feeding apparatus includes a first roll 106, and a second roll 108 arranged vertically below first roll 106, to feed a sheet material clamped between the first roll 106 and the second roll 108. The sheet material feeding apparatus further includes a first motor 102 provided with a rotatable first motor shaft 104 coupled to the first roll 106, and a second motor 103 provided with a rotatable second motor shaft 105 coupled to the second roll 108. The first motor shaft 104 and the second motor shaft 105 rotate at substantially the same rotation speed to allow the first roll 106 and the second roll 108 to rotate in synchronization with each other.
