Abstract
1,036,769. Making dies. MALEW ENGINEERING Ltd. Oct. 26, 1964 [Nov. 16, 1963], No. 45329/63. Headings B3A and B3W. A bolster plate, for a die of the type comprising a central core of wood or synthetic plastics material and a surround of similar material with one or more strip metal inserts therebetween, is characterized by the provision thereon of at least one bar provided with thrust means capable of engaging an adjacent side of a blanking die secured to the bolster plate, so as to resist any spreading of such side of said die. Fig. 2 shows a section through part of the bolster plate 10, the steel cutting insert 20 and the bar 14. The bar is drilled and tapped at 15 to receive a plurality of grub screws 18 which bear on pads 17 slidable in counterbores 16. Between the pads and the surround is a metal strip 19 which acts as a load spreader. It is stated that in practice it is found possible to make extremely fine adjustment of the cutting edge 20 by adjustment of the pressure applied by the pads 17.
