Definitions

  • This invention relates to an integrated cutting blade assembly used for cutting sheet members.
  • sheet members including surface cover members, members forming surfaces of articles of furniture, thin sheets of wood sheets of rubber, sheets of paper, etc., and they find wide ranges of applications.
  • the integrated cutting blade assembly of the present invention is especially advantageously utilized for cutting surface cover members covering the surface of seat, etc. installed in automobiles.
  • Surface cover members such as trim covers or moquettes used as covers for seats of automobiles are mass-produced by cutting a plurality of such surface cover members of standard dimensions at the same time by a set of cutting blades sized to conform to the desired shapes of the surface cover members.
  • a plurality of cutting blades 1A, 1B and 1 C as shown in Fig. 11 a are prepared, each of which is formed by bending a steel plate into the desired shape and welded endwise as shown at W in Fig. 11 a.
  • Such cutting blades are juxtaposed on a table 5 of a press as shown in Fig.
  • cutting blades 2A to 2E of various shapes required for cutting various parts of the surface of a seat are arranged as shown in Fig. 12a and, after being partly embedded and fixed in a plywood board 6 as shown in Fig. 12b, the assembly is placed on a table 5 of a press.
  • a rotary punching die consisting of a base plate which is bent so as to conform to the periphery of a punching drum and into which are inserted punch knives provided with a ground cutting edge and with a toothed rear edge.
  • the teeth of the rear edge of the punch knives are provided with upwardly directed barbs in the plane of the teeth, for the purpose of anchoring the punch knives.
  • US-A 3 786 732 there is disclosed an apparatus for cutting and scoring sheet-like material, comprising a single die plate which includes both severing elements and scoring elements mounted thereon.
  • the severing elements constitute the usual knife bladesemployed in the prior art sheet cutting and scoring dies.
  • the scoring elements constitute novel pairs of knife blades which eliminate the need for a conventional female die as required in prior art devices.
  • an integrated cutting blade assembly for cutting sheet members comprising a plurality of outer main blade sections, and a plurality of inner common blade sections, characterised in that said main blade sections are integrally welded to adjacent ones of the common blade section to form an integral assembly of cutting blades which provides in itself a sufficient mechanical strength from the structural aspect so that, for instance, a support in the form of a plywood board is unnecessary.
  • a first embodiment of the integrated cutting blade assembly of the present invention shown in Figs. 1a and 1 corresponds to the prior art example shown in Fig. 11 a.
  • the integrated cutting blade assembly shown in Figs. 1a and 1 b is intended to cut three sheet members having a shape substantially the same as that of sheet members cut by the three cutting blades 1 A, 1 B and 1 C shown in Fig. 11 a.
  • This integrated cutting blade assembly of the present invention comprises a plurality of outer main blade sections 3A and a plurality of inner common blade sections 3B and 3C. Such an assembly is formed by the steps of bending a web of steel into a form having three semicircular sections in each half as shown in Fig.
  • a second embodiment shown in Figs. 2a and 2b corresponds to the prior art example shown in Fig. 12a.
  • the integrated cutting blade assembly shown in Figs. 2a and 2b is intended to cut a plurality of sheet members having shapes substantially the same as those of sheet members cut by the cutting blades 2A to 2E shown in Fig. 12a.
  • common blade sections 4C, 4D, 4E and 4G are disposed inside of main blade sections 4A, 4B and 4F, and the former are welded to the latter at welds W as shown in Fig. 2b.
  • the integral formation of such a plurality of cutting blades provides a sufficient mechanical strength from the structural aspect, so that the plywood board 6 shown in Fig. 12b is unnecessary.
  • pipes 7A and 7B may be welded to the back side of the integrated cutting blade assembly to increase the mechanical strength as shown in Fig. 3, and another pipe 7C may also be welded in a relation orthogonal with respect to the pipes 7A and 7B as also shown in Fig. 3, so that the integrated cutting blade assembly can be carried by the bend.
  • Other blade sections, for example, blade sections 41 and 4J may be additionally provided.
  • a plurality of magnets 8A and 8B are preferably fixed to the integrated cutting blade assembly so that the integrated cutting blade assembly can be fixedly mounted on the table 5 of the press utilizing the magnetic force of these magnets.
  • the integrated cutting blade assembly may be mounted on the upper plate of the press.
  • the sheet-member engaging end of the cutting blade is to be finished to have a sharp edge.
  • the sharp edge may be tapered toward one side as shown in Fig. 9 or may be located intermediate the thickness of the cutting blade as shown in Fig. 10a.
  • the relation between the distance a from the sharp edge to one of the side faces of the cutting blade and the distance b from the sharp edge to the other side face of the cutting blade is preferably selected to be a> b.
  • the useful service life of the cutting edge engaged by the press table of steel can be extended beyond that of the cutting edge shown in Fig. 9.
