摘要： A saw blade, such as a bandsaw blade, has a toothform pattern that includes a raker tooth and set teeth. The bandsaw blade teeth are configured such that a distance from a tooth point of the raker tooth to a tooth point of an immediately preceding set tooth is the smallest tooth spacing in the saw blade toothform pattern. With the use of a smaller spacing, the raker tooth removes the smallest chip thickness from a work piece relative to the chip thicknesses removed by the set teeth. This reduces the amount of load imposed on the raker tooth point. In one arrangement, in order to balance the forces on either side of the blade during operation, the saw blade is configured such that an accumulated pitch of the tooth points set to a first side of the blade are substantially equal to the accumulated pitch of the tooth points set to a second opposing side of the blade.

摘要： A saw blade is provided with recurring groups of teeth. Each group of teeth includes one straight tooth, an even number of high set teeth, and an even number of low set teeth. Distances from all of the teeth in the group to a corresponding, immediately preceding teeth are different for all of the teeth. Distances from all of the teeth in the group to a preceding tooth of the same height are different for each tooth. Distances from all of the set teeth in the group to the nearest preceding set tooth with the same set are different for each set tooth. No high teeth are immediately adjacent.

摘要： A bandsaw blade for use in milling timber having in-line swaged teeth, wherein the cutting tip of each tooth, in front profile, is triangular in shape with a central apical point (30) and two side points (32, 34). Preferably, the apical angle (.theta.) is from 60.degree. to 140.degree., with the base angles (.gamma.) of the tip being equal to one another and lying from 20.degree. to 60.degree., thus providing an elongate pentagon shape in front profile. Also, a dark blue temper band (50) may be curved so that its top is spaced below the apical point (30) by a distance of 0.5 to 1.3 times, preferably 0.6 to 1.2 times, the blade thickness.

摘要： The invention provides a disconnectable band saw joint assembly for connecting together in axial alignment end portions of a bandsaw. The joint assembly does not require welding, and as such can be easily separated to permit threading of the bandsaw through a hole drilled in a plate to permit sawing of a closed ended cut or loop within the plate. This eliminates the normal practice of breaking and rewelding a band saw for cutting a closed loop within a plate. Furthermore, because the joint is cold, it does not affect temper of the saw portions adjacent the joint. The assembly has male and female connections, the female connections having a neck recess and a head recess, and the male connection having a head portion and a neck portion which fit within the neck recess and the head recess respectively. The recess has at least one main recess edge, and the head portion has at least one main head edge, both edges being disposed normally to longitudinal axis of the saw. When the jaw joint is under tension, the main head edge is in direct edge-to-edge contact with the main recess edge to permit limited hinging between the end portions about a main hinge axis coincident with the main edges and disposed normally to the saw axis.
摘要翻译： 本发明提供了一种用于在带锯的轴向对准端部连接在一起的可断开带锯接头组件。 接头组件不需要焊接，因此可以容易地分离，以允许带锯穿过板中钻孔，以允许在板内切割封闭的切口或环。 这消除了用于切割板内的闭环的带锯的断裂和再焊接的常规做法。 此外，由于接头是冷的，所以不会影响靠近接头的锯齿部的回火。 该组件具有阳和阴连接，阴连接件具有颈部凹部和头部凹部，并且阳连接件具有分别装配在颈部凹部和头部凹部内的头部和颈部。 所述凹部具有至少一个主凹口边缘，并且所述头部具有至少一个主头部边缘，两个边缘正常地设置在所述锯的纵向轴线上。 当钳口接头处于张力下时，主头部边缘与主凹口边缘直接边缘到边缘接触，以允许围绕与主边缘重合的主铰链轴线的端部之间的限制铰接并且正常设置于锯 轴。

摘要： A saw has a plurality of generally V-shaped teeth formed by punching. The sides of each tooth define cutting edges. A bevel extends along each cutting edge. The bevels are formed by punching with a tool having a surface oriented non-perpendicular to the saw blank. Burrs formed during the punching step are not removed, but are allowed to remain to enhance the cutting ability of the teeth.

摘要： Band saw blades embodying this invention are especially adapted for the cutting of hard metal work pieces of large cross-sectional size. The blades are characterized by a straight, planar sawtooth cutting edge and a tiered or stepped back edge, having alternate recessed and outer edge portions. Both the recessed and outer edge portions of the blade's back edge are generally parallel to the cutting edge of the blade and adjacent of these alternate edge portions are connected with inclined or tapered sections. The length of the recessed and outer edge portions are approximately equal; and when combined with the length of an inclined section, is about equal to the spacing of the saw guides of the band saw machine in which the blade is to be used.

摘要： A saw blade includes a body, saw blade teeth disposed on a first edge of the body, and a ramp element disposed on a second edge of the body, the second edge opposing the first edge. The ramp element is repeated along the longitudinal axis of the body to define a ramp element pattern. The ramp element includes a rise portion disposed proximal to a cutting direction of the saw blade and a relief portion disposed distal to the cutting direction of the saw blade. At least one of the rise portion and the relief portion of the ramp element defines a variable curve geometry.
