Abstract: A method and apparatus for controlling the cutting feed of band saw machines for obtaining an optimum feed rate with the same safety against straying of the saw cut, according to which the saw band is maintained continuously within the area of its teeth under a residual tensile stress (.sigma..sub.Z.sbsb.Res) adjusted at least approximately to a constant value. For this purpose, a desired value is selected for the residual tensile stress, determined experimentally under practical conditions, which is correspondingly converted in case of load conditions of the saw blade deviating from the experiment, and this desired value is compared with the actual value. The actual value (.sigma..sub.Z.sbsb.Res) is derived as a difference from the tensile stress (Z) in the critical saw band point and the bending stress .sigma..sub.B caused by the feed, to be .sigma..sub.Z.sbsb.Res =.sigma.Z-.sigma.B>0. The actual value is adjusted to the desired value by varying the feed rate; the sum total of all feed forces or the sagging angle of the saw band is selected as a measure for the actual value. As a result thereof the danger of straying is precluded and yet an economically optimal feed rate is attained in band saws.
Abstract translation: 一种用于控制带锯机的切割进给的方法和装置，用于以相同的安全性获得最佳进给速度以抵抗锯切的偏差，根据该方法和装置，锯条在残余拉伸应力下连续保持在其齿的区域内 （sigma ZRes）至少调整到一个恒定值。 为此，对实际情况下实际确定的剩余拉伸应力选择期望的值，在锯片的载荷条件偏离实验的情况下相应地进行转换，并将该期望值与实际值进行比较。 实际值（sigma ZRes）被导出为与由进给引起的临界锯带点和弯曲应力σB的拉伸应力（Z）的差值，为sigma ZRes = sigma Z-sigma B> 0。 通过改变进给速率将实际值调整到所需值; 选择所有进给力的总和或锯带的下垂角作为实际值的量度。 因此，排除了偏差的危险，并且在带锯中获得了经济上最佳的进料速率。

Abstract: A band sawing machine has an endless saw blade entrained over two saw pulleys and two blade guides. Lateral displacements of the saw blade from a preset position occurring during a sawing operation are measured by a position sensor. The position sensor controls an actuator which applies a corrective twist or lateral movement to at least one of the blade guides to return the blade to the present position.

Abstract: A deviation detecting apparatus for a bandsaw blade in a bandsaw machine has an arm pivotally mounted at a location adjacent to the linear path of travel of the blade through the cutting zone. The arm is yieldably urged into slidable contact with one side of the blade, and is thus pivotally movable in response to lateral deviations of the blade. A control device is responsive to pivotal movement of the arm. The control device generates a control signal indicative of blade deviations.

Abstract: A control system for a band saw blade. Two groups of rollers are arranged with respect to the blade so that the first is in contact with set and gullet area of the blade and the other is arranged to be adjacent to, but not in contact with the trailing edge. When the band saw blade is deflected, the first set of rollers act as a fulcrum, about which the blade pivots so as to cause the blade to return to its original path, thus permitting it to cut in a straight and smooth line. The rear rollers are correction limiting rollers, and are used to prevent over-steering of the band saw blade.

Abstract: A band saw having a generally vertically oriented saw blade carrying frame mounted to a movable carriage is disclosed. The carriage is mounted in a horizontally extending guideway in the saw base by an arm which is cantilevered from the back side of the vertical saw frame for support and guided motion of the saw from a relatively debris free portion of the saw base. Additionally, the band saw includes a work piece supporting bar feed table having a movable vise which is stabilized against backward tilting and a roller support assembly constructed so as to accommodate load concentrations from heavy, bent bar stock. Finally, an improved band saw blade guiding assembly is disclosed.

Abstract: A band saw machine is provided with a cutting head that carries the endless saw blade. The cutting head can be swung from a vertical cutting plane into a horizontal cutting plane. Limits can be made in the feeding stroke of the cut and the return travel. A workpiece feeding and clamping vice is rotated about a horizontal axis. The combined positioning capability of the band saw blade and the workpiece vice allows difficult compound angular cuts to be made in the workpiece. The endless run of the blade is angled upwardly and outwardly away from the workpiece to provide additional clearance for cutting deep workpieces. Powered feed rolls advance the workpiece against a gauging stop to determine a predetermined length to be cut. The vice is then closed to hold the workpiece during cutting. Supplemental supports hold the rearward end of the workpiece during feeding and cutting. Blade guides are spaced for accomodating both small and large width blades.

Abstract: A rotary turret numerically controlled punch press is provided with a discharge station at 90.degree. from a punching station. A part is clamped in the turret, separated from a larger workpiece and then rotated with the turret to the discharge station. A transfer arm is slaved to the NC punch press and engages the part at an exact attitude and position relative to a reference point on the part and transfers the part to a rotary chuck. The part is placed in the chuck at an exact attitude and with the reference point at the axis of rotation of the chuck.Four rotary chucks are provided on a rotary turret contouring apparatus. The turret is rotated 90.degree. to position the part at a cutting station.A band saw is provided with rotary guides for changing the angle of the saw. While the part is rotated and linearly translated toward and away from the saw by the contouring apparatus, the saw cuts a peripheral shape on the path with the blade changing its angular attitude where necessary. An air cushion support holds the edge of the part at the saw blade.After cutting, the contouring turret is rotated another 90.degree. bringing the part to a deburring station. The motion of the part at the deburring and cutting stations is identical for simultaneous cutting and deburring. Next the turret is rotated another 90.degree. and the deburred part is engaged by a second transfer arm to remove the part and locate it for subsequent treatment.

Abstract: A bandsaw machine is provided with a device in which a check valve having a tappet or projection and a flow control valve are provided in parallel with each other in a hydraulic passage connecting a hydraulic pump with a hydraulic cylinder for raising a cutting head holding a bandsaw blade, a micro switch is electrically connected with an electric motor for driving said pump and a solenoid operated valve for controlling hydraulic fluid through a time limit switch, a vertical elongate rod is vertically movably mounted on a part of said cutting head and is provided at its bottom end with an horizontally elongate plate which is touchable with a material to be cut, a horizontal elongate plate is fixed to the top end of said vertical elongate plate so as to depress said tappet or projection of said check valve and actuate said micro switch. The vertical elongate rod is so designed as to be brought into and out of contact with the material to be cut in order to automatically determine the upper limit of the vertical movement of the bandsaw blade and automatically control the lowering speed of the bandsaw blade during its idle time.

Abstract: A band saw has top and bottom guides both pressing a sawing section of a saw band out beyond a line tangent to top and bottom wheels of the band saw. The guides include holders having sockets into which guide blocks are inserted, and adjustment screws on the guide blocks abut adjustment screws on the guides to precisely locate guide faces of the guide blocks. A milling machine has a holder for receiving one of the guide blocks in a position engaging the adjustment screws of that guide block, and mills the guide face a predetermined distance from the adjustment screws. A quality control jig receives the guide block and indicates when the guide face is the desired distance from the adjustment screws.
