摘要： A method of creating a piston crown is disclosed. The method includes the step of providing a billet and then upsetting the billet in a first station to generally decrease a length of the billet and generally increase a cross section of the billet. The billet is then pre-formed in a second station into an intermediate configuration of a piston crown, where the piston crown is in a preliminary shape. The first station and the second station are separate components. The intermediate configuration of the piston crown is formed into a final shape of the piston crown, where the final shape includes a predetermined volume. The piston crown is then precision formed into a near net shaped configuration, where the near net shaped configuration of the piston crown includes a near net shaped volume. The predetermined volume may be approximately equal to the near net shaped volume.

摘要： A method of improving the surface finish of a sheared end face of a cylindrical blank in a progressive forming machine comprising deforming the end face out of its original as sheared transverse plane into a first shape concentric with the axis of the blank that slightly departs from the original plane a distance that increases with proximity to the axis of the blank, thereafter deforming the end face from the first shape into a second shape in a direction opposite a direction the first shape was displaced from the original shear plane, the second shape slightly departing from a transverse plane a distance that increases with proximity to the axis of the blank.

摘要： The conventional techniques cannot minimize increase in yield loss and slab thickness caused by unsteady deformation in top and rear end portions during reduction of the width of a slab, and cannot shape a slab with desired target dimensions at high productivity. With respect to a width pressing machine 2 that reduces the width of a slab, a horizontal rolling mill 1 is arranged at the upstream side of the slab conveying direction, or an entry-side horizontal rolling mill 1 and an exit-side horizontal rolling mill 3 are respectively arranged at the upstream side and downstream side. A slab shape control equipment thus configured is used to simultaneously perform rolling by the horizontal rolling mill 1 or by horizontal rolling mill 1 and horizontal rolling mill 3, and reduce the width of a slab by the width pressing machine 2 on one hot slab 10.

摘要： When manufacturing a ring and a pendant from a single metal plate, the number of the twist is determined so that a predetermined feature pattern may occurs regardless size on the surface of a male ring and a female ring. The feature pattern depends on the method of the laminating of two or more metal plates, the kind of metal plate, thickness, etc. for example. The number of times of twist concerned is determined based on these information,

摘要： The present invention discloses a process of manufacturing forged components using a combination of open die and closed die forging, and machining. The process involves the steps of cogging of the ingot, upsetting the cogged bloom in two steps to form a preform, closed forging the preform on a hammer, rough machining, heat treatment, semi-finishing, and finally finishing the component. The present invention is applicable to any forged components that are used in variety of industries, particularly those which are formed from large ingots. The invention is particularly useful for safety- and application-critical components such as a fluid end which is used in oil and gas industry. With the process of the present invention, 55 to 60% of the shape and size of the final component is achieved through forging and remaining 40 to 45% through machining. Incorporating the closed die forging stage in between open die forging and machining stages of the results in about 27% material reduction and over 60% reduction in machining time.
