Press tool stripper plate and ejection pad - is made from polyurethane foam to reduce overall tool height and setting up time

The punch (10) and the matrix (12) of a press tool are normally equipped with a spring loaded stripper plate and ejection pad which are made from metal. When the tool, fixed to a pillar block (1, 2, 3) is set up on a press, a sheet of expanded polyurethane is placed between punch (10) and matrix (12) after which one cutting stroke of the tool is required. This places a cut out from foam inside the matrix to form an ejection pad (18). The remainder of the polyurethane sheet locates itself around the punch to function as stripper plate (19). This method allows a reduction of the overall height of the tool as well as a simplified setting up procedure.

本发明涉及一种电器柜钣金冲压成型加工方法，包括工作台、运输装置与冲压装置，所述工作台左侧前端固定安装有运输装置，工作台上端中部固定安装有冲压装置，所述运输装置包括电机一、齿轮一、齿轮二、链轮一、齿链带一、链轮二、齿链带二、皮带与支撑板，本发明通过运输装置对板材进行定位以及间歇式运输，整个过程中无需人工进行控制，通过冲压装置对板材进行落料、拉伸以及冲孔加工，整个过程中，开设有落废料孔的凸模一与板件表面完全接触，从而使板件表面完全受力，同时在冲孔的过程中对板件上的孔进行打磨，无需后续进行加工。

Method and apparatus for punching a thin metal tape to patterned member

스트립퍼판을 보유하는 스트립퍼홀더는 다이판의 변형에 일치하고 이러한 목적을 위하여 스트립퍼판에 가해지는 압력은 금속테이프에 탄성한계보다도 펀치되기 위하여 더 크고 금속테이프가 누르는 변형력이나 파손력보다 더 적게 만들어진다. The stripper holder holding the stripper plate corresponds to the deformation of the die plate and for this purpose the pressure exerted on the stripper plate is made larger and less than the strain or breakage force that the metal tape presses to punch more than the elastic limit on the metal tape. 기타의 고려사항은 스트립퍼홀더가 신축적이고 금속테이프는 상이한 압력에 의해서 하나의 펀칭위치에 대하여 두개의 상이한 위치에서 압력을 받도록 만들어진다. Other considerations are that the stripper holder is flexible and the metal tape is made to be pressurized at two different positions relative to one punching position by different pressures.

Raceway ring producing method

该轴承环制造方法包括在成形台上放置被加热至A 1 相变点以上的温度的钢材的第一步骤以及在从钢冲压出环形构件之后在成形台上成形和淬火环形构件的第二步骤。冲压模具(30)被构造成可分成内筒(30B)和外筒(30A)。在第二步骤中，通过将内筒(30B)的末端和外筒(30A)的末端压入线圈材料(2)来从线圈材料(2)冲压出环形构件(2A)。通过进一步将内筒(30B)的末端压入环形构件(2A)，同时环形构件(2A)被保持在外筒(30A)与成形模具(32)之间来执行冲压出的环形构件(2A)的成形工艺和淬火工艺。因此，可以提供维持轴承环的良好成形精度且进一步缩短制造工艺的轴承环制造方法。

Apparatus for manufacturing end-cap of heater core for automobile

According to the present invention, an apparatus for manufacturing an end cap of a heater core in a vehicle includes a blanking mold having a blanking punch blanking a metal plate to form a base metal plate; a pipe cap drawing mold having a pipe cap drawing punch drawing the base metal plate to form a first uplifting portion having a shape corresponding to a shape of an end of a pipe for coolant flow; a header tank cap drawing mold having a header tank cap drawing punch drawing the base metal plate in which the first uplifting portion is formed to form a second uplifting portion having a shape corresponding to a shape of an end of a header tank for temporarily storing the coolant in the base metal plate; a piercing mold having a piercing punch piercing a center of the first uplifting portion to form a penetration hole for inserting the end of the pipe; and a trimming mold having a trimming punch trimming an edge of the second uplifting portion to cut a strap portion at the edge of the second uplifting portion.
