试制车间小批制造的凹、凸模,一般装在相配的模座内。凸模座夹固的凸模外径尺寸较宽广,而冲裁模的凹模座则甚复杂。生产中要备几种凹模座,这样,费工又费料。现设计、制造并已使用了可换凹模的夹紧装置(图1),它能夹紧各种不同外径的冲裁模、弯曲模、成型模的凹模,且外径尺寸范围宽广。带60°的V形块1固紧在平板2上,其中心有长形孔穴3。平板2的一端有侧板4,制动螺钉5和夹块6。夹块恒定地支靠在平板上,其下部有支承件7。该支承件位于长形孔穴内,其上平面齐平于平板的上平面。大直径的圆凹模8(虚线所示)装在V形块内,用
Trial workshop small batch manufacturing concave, punch, generally fitted in the matching mold base. Punch Block clamping the punch outer diameter larger size, and die die cavity is very complex. In the production of several kinds of mold base, so that labor and material. Now, we have designed, manufactured and used interchangeable die clamping device (Figure 1), which can clamp different sizes of punching die, bending die and forming die with wide range of outer diameter . The V-shaped block 1 with 60 ° is fastened to the plate 2 with an elongated hole 3 in the center. One end of the plate 2 has a side plate 4, a brake screw 5 and a clamp 6. The clamps constantly rest against the plate, with the support part 7 in the lower part. The support member is located in the elongated hole, the upper plane of which is flush with the upper plane of the plate. A large diameter circular die 8 (shown in phantom) fits inside the V-shaped block
