109results about How to "Reduce forming load" patented technology

A data processing apparatus that is capable of improving the accuracy with which form types can be identified. An image file of a form and an additional file including a form type ID of the form are inputted. A character recognition process on the image file is carried out based on the form type ID. The image file and a result obtained in the character recognition process are stored in a storage device 103.

The invention discloses a multi-point male die liquid-filling drawing forming device and a multi-point male die liquid-filling drawing forming method for a plate, relates to a device and a method for forming thin-walled curved plate parts, and aims to solve the problem of difficulty in forming of thin-walled and deep-cavity parts with complicated curved surfaces. A plurality of small punches are independently arranged; the upper ends of the small punches penetrate into through holes in a male die body; the upper end of each small punch is connected with a linear driving device; a female die is a semi-closed cavity of which the upper end is opened and the lower end is closed; an elastic base plate and a metal protection plate are superposed on the upper end surface of the female die from bottom to top. The heights of the small punches are adjusted to realize the construction of an outer contour of a multi-point male die; a to-be-formed plate blank, the elastic base plate and the metal protection plate are sequentially arranged on the upper end surface of the female die; a blank holder moves down to be assembled with the female die, and the multi-point male die moves down and applies a drawing force to the to-be-formed plate blank; meanwhile, a liquid medium is filled into an inner cavity of the female by the aid of a pressurizing system until drawing is completed to obtain parts of a required shape. The device and the method are used for forming the plate, and the thin-walled and deep-cavity parts with the complicated curved surfaces can be formed.

A high-strength steel plate has a component composition including, in mass%, C: 0.02-0.3%, Si: 1-3%, Mn: 1.8-3%, P: 0.1% or less, S: 0.01% or less, Al: 0.001-0.1%, N: 0.002-0.03%, the rest consisting of iron and impurities. The steel plate has a structure including, in terms of area ratio relative to the entire structure, each of the following phases: bainitic ferrite: 50-85%; retained gamma: 3% or greater; martensite + the aforementioned retained gamma: 10-45%; and ferrite: 5-40%. The C concentration (C[gamma]R) in the aforementioned retained austenite is 0.3-1.2 mass%, part or all of the N in the aforementioned component composition is solid solution N, and the amount of the solid solution N is 30-100 ppm.
