摘要： The machine tool comprises a frame (1, 2, 3) with two fixing elements (22 and 39) for fastening a scroll saw blade. The fixing element (22) is driven by an electrical motor (5) in a vertical reciprocating movement. The two fixing elements (22 and 39) are linked to each other by a metallic ribbon (45) passing on pulleys (46 to 50). The position of the pulley (47) can be changed by means of a cam (53) acting on an arm (52) so as to stretch the ribbon (45) to the desired value.

摘要： An equilibrium apparatus of cut-off mechanism for high-speed nut former which includes a cutting unit carrying a cutting tool thereon, and a counterweight unit carrying a counterweight unit thereon. The cutting unit and the counterweight unit are connected pivotally to a coupling unit which is fixed on the machine table of the nut former at the central portion thereof so that the cutting unit and counterweight unit are capable of effecting straight motion. A push plate is drivable to move in a first direction so as to push the cutting unit and the counterweight unit to move in a second direction perpendicular to the first direction in such a manner that only one of the cutting unit and the counterweight unit is pushed. A spring device is disposed on the cutting unit and the counterweight unit for absorbing the shock produced from the cutting action of the cutting tool and for biasing the cutting unit and the counterweight unit to move in a third direction which is opposite to the second direction. The cutting unit and the counterweight unit are always moved in opposite directions so that the equilibrium of the cut-off mechanism is achieved.
摘要翻译：一种用于高速螺母成型机的切断机构的平衡装置，其包括在其上承载切割工具的切割单元和在其上承载配重单元的配重单元。切割单元和配重单元枢转地连接到联接单元，该联接单元在其中心部分处固定在螺母成型机的机台上，使得切割单元和配重单元能够进行直线运动。推板可驱动以沿第一方向移动，以推动切割单元和配重单元沿垂直于第一方向的第二方向移动，使得只有一个切割单元和配重单元被推动。弹簧装置设置在切割单元和配重单元上，用于吸收由切割工具的切割动作产生的冲击并且用于偏压切割单元和配重单元以沿与第二方向相反的第三方向移动。切割单元和配重单元总是沿相反方向移动，从而实现截止机构的平衡。

摘要： This invention relates to gang saws and other cutting apparatus having oscillating cutters for cutting workpieces into slices. The invention provides apparatus, having two elongate spaced apart cutter supports which are driven to oscillate 180.degree. out of phase with each other. Two sets of cutters are connected to the supports. For a suitable workpiece the cutters may be of a hot wire type. Each cutter of one set is connected to the first support by a resiliently extensible connector such as a spring and to the second support by a non-extensible connection. Each cutter of the other set is connected to the second support by a resiliently extensible connector and to the first support by a non extensible connection. Desirably the cutters of one set alternate with cutters of the other and all cutters are coplanar. Movement of cutters of each set in opposite directions tends to cancel the local influence of cutters on the workpiece. Moreover whole frames of cutters may be removed and replaced, facilitating reprogramming of the apparatus in terms of spacings between cutters.
