Thus, it is possible to provide a sheet processing apparatus that can stack folded sheet bundles with reliability and to improve the image forming efficiency.

The invention relates to a screw bolt with isothermal oil for cooling the inner wall of the front section of an EPE/EPS single screw bolt foaming extruding machine, which belongs to the field of single screw bolt foaming extruding machines taking LDPE/GPPS as main raw materials according to the principle of physical foaming by injecting foaming agent to produce EPE/EPS sheets. The invention solves the technical problem that the prior EPE/EPS single screw bolt foaming extruding machine can not cool material sectionally, thereby influencing the quality of products. The invention adopts the technical scheme that the centers of the front section and the rear section of the screw bolt are provided with different oil returning channels; cooling oil is pumped into the bottom end of a central blind hole in the front section of the screw bolt after passing through a small oil inlet pipe to return through the inner wall of the central blind hole in the front section of the screw bolt and enters a passage between a small oil inlet pipe and a large return pipe in a central through hole in the rear section of the screw bolt after cooling the front section of the screw bolt; and because an air heat-insulating layer exists between the inner wall of the central through hole in the rear section of the screw bolt and the outer wall of the large return pipe, the cooling oil can not cool the rear section of the screw bolt. The invention can be widely applied to the field of processes requiring the material cooling sectionally.

A tool system for brake forming having a punch or a die and at least one insert. In one embodiment, two inserts are removably attached to a die. The die has a defined shape running along a longitudinal axis. Each insert has a protrusion with a particular cross-sectional shape running along the same longitudinal axis. The die has two cavities, each cavity having a cross-sectional shape matching the cross-sectional shape of the protrusion of one of the inserts. In another embodiment, the die has two protrusions and each insert has a cavity for receipt of one of the protrusions of the die. When one of the protrusions is inserted into one of the cavities, the insert is removably fixed to the die. At least one surface of each insert corresponds to and combines with the defined shape of the die, forming a bending surface against which a sheet of metal is formed. After press braking, the sheet of metal is substantially conformed to the defined shape of the die. In another embodiment, an insert is removably attached to a punch such that the insert forms the entire surface of the punch system that contacts the sheet of metal to be shaped during press braking. The inserts are positioned such that they encounter most of the wear caused by the brake forming, whereas the punch and the die encounter only minimal wear. As a result, the inserts are inexpensively repaired or replaced when needed, but the punch and the die remain in good condition during extended use.
