This application describes the creation of a wheel disc for a trailer using a three-hit manufacturing process.

A seat slider device may include a lower rail attachable to a body of a vehicle; and an upper rail attachable to a lower portion of a seat and slidably engaging with the lower rail. The upper rail may include a lock pin movable along a short direction of the upper rail. The lower rail may include a plurality of first holes and a second hole. The first holes may be arranged along a longitudinal direction of the lower rail and configured to engage with the lock pin, and the second hole may be arranged with the first holes along the longitudinal direction of the lower rail. The second hole may be positioned at a position where the lock pin is incapable of engaging with the second hole or the second hole may have a size with which the lock pin is incapable of engaging.

A method for manufacturing a tear-off lid (27). A lid blank (9) is punched with a punching tool (1, 5) having a die (6) and a cutting punch (2, 3) to form a lid ring (8) with a central removal opening (17) surrounded by a sealing flange (18). The edge of the removal opening (17) is then formed by drawing to a collar (20) projecting from the sealing flange (18) on the intended inside of the lid (underside), the collar (20) is rolled up at its free end and a tear-off foil (24) is sealed or glued onto the sealing flange (18) on the intended outside of the lid (upper side).

In accordance with the invention, the die (6) is arranged on the inner side (bottom) of the lid and the cutting punch (2, 3) is moved into the die (6) from the outer side (top) of the lid while punching out a punched pad (16) and the punched pad (16) is conveyed by compressed air through the die (6) to a conveyor (33) by means of which it is removed from the tool area.

It has been shown that by this measure the known and established processes and devices for the production of tear-off lids can be modified with very little effort in such a way that during the punching of the lid blank (9) the punching or cutting pad is produced on the intended inner side (underside) of the produced lid ring (8), which is desirable when producing lids with “re-verse curl”.

A method is executed to make a reel assembly of a tie-down. The method includes the steps of providing a ratchet with teeth and slots, providing a spool with protuberances, connecting the ratchet to the spool by inserting the protuberances of the ratchets in the slots of the spool, and enhancing the connection of the ratchet to the spool.

The invention relates to a method for manufacturing a centrifugal pendulum (1) as well as a centrifugal pendulum (1) which is manufactured using said method and which comprises pendulum components (13, 14) made of sheet metal, i.e. a pendulum mass support (2) that is arranged about an axis of rotation (d), and pendulum masses (3) that are distributed about the circumference. In order to reduce tool costs and the cost per item, at least one punched blank (9) comprising at least two pendulum components (13, 14) is manufactured, whereupon the pendulum components (13, 14) are separated from one another.

A spot weld removal punch preferably includes a punch body, a centering pin, a venting roll pin and a compression spring. The punch body preferably includes a punch shank, a body portion and a punch flange. The punch shank extends from one end of the punch flange and the body portion extends from an opposing end of the punch flange. A pin bore is formed in the end of the body portion to receive the centering pin and the compression spring. The venting roll pin is transversely inserted into the pin bore to retain the centering pin. A second embodiment of a spot weld removal punch preferably includes a punch body, a centering pin, a pin retention device, a replaceable impact head and a compression spring. The replaceable impact head may be replaced when thereof wears out.

A method for optimizing production of sheet-metal parts, the production comprising cutting out and singularizing the sheet-metal parts and bending the sheet-metal parts, wherein the method includes: (A) training a neural network, which is executed on a Monte Carlo tree search framework, by means of supervised learning and self-play with reinforcement learning; (B) recording constraints for the sheet-metal parts, the constraints comprising geometric data of the sheet-metal parts; (C) creating an optimized production schedule by way of the neural network; and (D) outputting the production schedule.
