A method of and device for removing burrs from metal work-pieces processed by a metal processing machine is provided. The method and device both include the burrs being removed by a high pressure stream of liquid that exits a high pressure nozzle and is directed at the work-piece that is to have the burrs removed. An integration of the burr removal step into the manufacturing sequence of the parts on commercial metal processing machines is made possible by the fact that the high pressure stream of liquid that is used has a proportion of oil of greater than 50% and a high pressure of greater than 400 bar.

The present invention provides a pipe body of which the edge sections contact with each other stably and which can be formed only by means of only a press processing without performing a welding mass-producing, wherein separation-prevented engagement due to deformation of at least one of the engagement sections absorbs the spring back in the press processing. Also, the present invention provides a pipe body, a metal plate for the pipe body and a forming method of the pipe body using the sheet metal for the pipe body. The pipe body includes a pair of edge sections 1e, 1f forming closed end surface by means of contact with each other, wherein surroundings of each edge sections 1e, 1f form a plane 1a jointly when each edge sections 1e, 1f are in contact with each other, and at the same time, engagement sections consisting of female engagement section 1g and male engagement section 1h engaged with each other are formed in the edge sections 1e, 1f, and the edge sections 1e, 1f get in contact with each other closely by means of separation-prevented engagement due to deformation of at least one of the female and male engagement sections 1g, 1h.
摘要:
Embossed sheets having improved grain retention can be made from a polyolefin composition containing a propylene polymer material, a partially crosslinked thermoplastic olefin elastomer composition, and optionally, crystalline polyethylene. Large parts such as automobile door and instrument panels can be formed from these sheets.

An efficient method of forming a vehicle body side panel from a blank constructed to reduce wasted material and manufacturing time. The method includes connecting first and second opposing sheet members and first and second middle sheet members to form the blank. The sheet members being spaced from each other such that an opening extends through the blank. The opening having an original perimeter that is formed by the first and second opposing sheet members and the first and second middle sheet members. The method also includes removing a portion of one of the sheet members adjacent the opening to remove a section of the original perimeter of the opening and to enlarge the opening beyond its original perimeter.
摘要:
A method of processing the connecting surfaces between a marine engine frame and an associated bearing support, which parts wholly or partially surround a crankshaft is presented. The bearing support is removed to expose the connecting surface of the engine frame facing towards the bearing support. An auxiliary plane is established which is set-up/extended along the centerline of the crankshaft, and a second line at right-angles to the centerline. In situ processing of the connecting surface of the engine frame is effected at an angle which is a function of the position of the auxiliary plane. It is thus possible to process the connecting surface of the engine frame facing towards the bearing support without the necessity of having to remove the engine frame itself, and to carry out the processing of at least this free connecting surface, while the actual bearing support can be processed in the normal manner.
摘要:
A method of providing an internal circumferential shoulder in a cylindrical passageway including the steps of forming an enlarged internal diameter groove in the passageway, machining an integral unitary circumferential shoulder blank of external dimensions conforming to the groove, cutting the shoulder blank into at least segments, each segment having opposed end surfaces that match the end surfaces of adjacent segments, the opposed end surfaces of one segment being defined by parallel, spaced-apart planes forming a key segment, positioning the shoulder segments into the groove, the key segment being inserted last and securing the key segment within the groove.
