摘要： The present invention discloses a current-assisted composite spinning forming device and method for deep cup-shaped thin-walled parts is provided, comprising a spinning mandrel, a tailstock, and a plurality of rollers evenly distributed on the circumference of the spinning mandrel; the rollers are arranged in a staggered manner in the axial and radial directions of the spinning mandrel, and the roller surface of each roller comprises a deep drawing roller surface, a flow spinning section, and a shaping roller surface, wherein the staggered arrangement means that the deep drawing roller surfaces, the flow spinning sections and the shaping roller surfaces of the rollers are distributed in a staggered manner in the axial and radial directions of the spinning mandrel. In the spinning process, with different arc-shaped surface shapes and structures of the rollers for deep drawing spinning, the rollers focus on applying pressure to different portions of a blank in the period of each revolution of the spinning mandrel, which is beneficial to increase the pass reduction and reduce the spinning pass. This can not only improve the production efficiency, but also contribute to reducing defects such as material rupture and unusability due to hardening of the workpiece that is caused by the discontinuous material forming process.

摘要： A die for deforming a workpiece material in a joining tool comprises a head with a top side partially defining a cavity in which the workpiece material is to be deformed, a bottom side opposite the top side, a lateral side arranged between the top side and the bottom side, and a stem which extends along a longitudinal axis from the bottom side of the head. The die further comprises an identification tag, preferably an RFID tag, having an antenna for receiving and/or transmitting a signal, and a storing element for storing information, and the antenna is wrapped circumferentially around the head, such that the antenna entirely surrounds the head. The head may also include a groove extending around the head on the lateral side with the antenna arranged in the groove. Additionally, the die may include a recess with the storing element located in the recess.

摘要： A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

摘要： Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a continuous strip material positioned between an entry and an exit of an apparatus. A sensor determines a measured distance between an upper surface of the strip material and a reference location, where the sensor is downstream from the exit of the apparatus. A controller determines a difference value between the measured distance and a predetermined distance to detect material curvature in the strip material.

摘要： A press device for forming a work piece includes a punch and an adjustment mechanism. The punch is configured to move along a punch stroke toward a work piece located in a punch zone below the punch. The punch is configured to engage the work piece during the punch stroke to form the work piece. The adjustment mechanism is coupled to the punch. The adjustment mechanism includes an actuator and a transfer member. The actuator is rotationally coupled to the transfer member. The transfer member is operably coupled to the punch. The actuator is configured to rotate. The transfer member converts the rotational movement of the actuator into translational movement that advances the punch linearly from a first operative position relative to the punch zone to a second operative position relative to the punch zone to adjust a bottom location of the punch along the punch stroke.

摘要： An upper die is removable in an up-down direction with respect to an upper die mounting groove that is arranged in a left-right direction at a lower part of an upper table of a press brake. The upper die includes a stop piece having a stop projection that is engageable with a stop groove that is formed in the left-right direction in each of upper die contact faces which face each other in a front-rear direction, the stop piece being movable out of and into a surface of the upper die and pushed in a direction to project out of the surface of the upper die. A bottom face of the stop projection for engaging with the stop groove is an inclined face that rises toward a front end of the stop projection.
