Title: Improvements in or relating to presses for riveting or the performance of analogous operations
IPC: B21J15/20
Filed: 1949-09-23
Abstract: 681,714. Riveting. STEELS & BUSKS, Ltd., and CLARKE, A. Aug. 31, 1950 [Sept. 23, 1949], No. 24499/49. Class 83 (iv). [Also in Group XXIX] A riveting or like press comprising an anvil and a relatively movable head is characterized in that the movable head has an operating member which drives the head in the pressclosing direction but is movable thereto, when the head encounters opposition, to shut off a supply of hydraulic fluid and to apply the entrapped fluid under pressure for performing the pressing movement. The press comprises a standard 1 carrying a horizontal bed 3 on which is bolted a recessed fixture 4 having a nose 5 overhanging a movable head 7 disposed in the recess 6. The head 7 which has arms 8 carrying splaying elements 11 on platens 10 is guided on a vertical rod 12 and balanced by a counterweight 18. A treadle 20 operates a connecting-rod 28 secured at 29 to the bottom of a yoke 30 slidable on a vertical piston 34. A compressor spring 37 is arranged around the piston 34 between a yoke 33 and a plate 38 on the head 7 into which the piston 34 projects. A larger parallel bore 41 in the head 7 accommodates a piston 43 secured in the nose 5. A passage 45 connects the bores 39 and 41. When the head is retracted a reduced part 48 on the piston 43 abuts against a plug 42 and a projection 49 on the part 48 enters a recess in the plug. A reservoir 50 in the head 7 supplies oil through a port 51 to the bore 39. For riveting hasp locks to suit-cases the bed 3 is provided with grooves 53 which receive a rib 54 on a fixed anvil 55 recessed to receive a lock-plate 56 with four rivets 57. In operation, as the treadle 21 is depressed the piston 34 moves downwards and depresses the head 7 through the spring 37 whereupon the head part 48 of the piston 43 separates from the plug 42, thus allowing more oil to flow into the enlarged working space in the bore 41. When the splaying elements 11 encounter the rivets the spring 37 absorbs the back-thrust of the head 7 but the piston 34 enters further into the head 7 and closing the port 51 forces the fluid into the space 52 in the bore 41 and completes the riveting operation. When the treadle is released the spring 37 returns the piston 34 which opens the port 51 and allows the oil to flow back into the reservoir 51 and the head to ascend to its starting position. A return spring may be fitted to the treadle to assist this restoring action. Specification 647,623, [Group XXV], is referred to.
