Prestressed tension plate high-efficiency high-accuracy machining technology
The invention discloses a prestressed tension plate high-efficiency high-accuracy machining technology. A prestressed tension plate comprises a center hole, circular corners, threaded through holes, countersink holes, strip-shaped grooves and chamfers. The prestressed tension plate high-efficiency high-accuracy machining technology comprises the following steps that cutting operation is conducted,specifically, a plate shearing machine is adopted to conduct strip cutting operation, and then a square plate is cut; the center hole is punched, specifically, the large circular center hole is punched by a punching machine; the countersink holes, the through holes, the strip-shaped grooves and the chamfers are punched, a convex mold is rotated, and the countersink holes are punched through primary punching operation; after rotation resetting is conducted, the rest of characteristics are punched through secondary punching operation; tapping operation is conducted, specifically, a multi-shafttapping machine is used, each through hole and each screw tap corresponds to a locating pin, and self-centering machining is conducted; and edge planing operation is conducted, specifically, a push-and-pull oil cylinder is installed on a planing machine, and an upper planing tool and a lower planing tool are arranged on the two sides of a track. According to the prestressed tension plate high-efficiency high-accuracy machining technology, the number of the tension plate machining steps is reduced, and the transfer work is reduced; and the countersink holes, the through holes, the strip-shapedgrooves, the circular corners and the tapping operation are positioned at one time and simultaneously machined, the positioning accuracy is improved, and the machining efficiency is improved.
本发明公开了一种预应力张拉板高效高精度加工工艺，所述预应力张拉板包括中心孔、圆角、螺纹通孔、沉孔、条形槽、倒角，其包括以下步骤：裁剪,采用剪板机切条再切方板；冲中心孔，通过冲压机将中心大圆通孔冲出；冲压沉孔、通孔、条形槽、圆角机,旋转凸模具，一次冲压将沉孔冲出；旋转回正后，二次冲压剩余特征；攻丝,多轴攻丝机，每个通孔、丝锥对应一个定位销自定心加工；刨边,刨床安装有推拉油缸，轨道两侧设置上下刨刀。本发明减少了张拉板加工步骤，减少了转运工作；沉孔、通孔、条形槽、圆角、攻丝均一次定位，同时加工，提高了定位精度，提高了加工效率。
