    摘要: A roll forming apparatus for forming projections on a band plate at predetermined internals with respect to a longitudinal direction of the band plate has a carrying roll between an upstream forming roll unit and a downstream forming roll unit. Projections having a first shape are formed on the band plate by an upstream projection forming roll and an upstream recession forming roll of the upstream forming roll unit. The projections having the first shape are formed into projections having a second shape that is steeper than the first shape by a downstream projection forming roll and a downstream recession forming roll of the downstream forming roll unit. Also, the band plate is carried in a sprocket manner that the projections formed in the upstream forming roll unit sequentially engage with projections of the upstream projection forming roll, recessions of the carrying roll, and projections of the downstream projection forming roll.

    摘要: A die roll 3 comprises a core part 3a which is formed of an elastic material and faces a punch part 2a of a punch roll 2. The core part 3a presses a bottom portion 4b of a drawn portion 4a of a metal material 4 and is separate from a surrounding die part 3b and is provided with a space 3c at the whole outer periphery of the core part 3a. In accordance with the above configuration, swelling is suppressed at the bottom portion 4b of the drawn portion 4a and production of large wrinkles, which is a reason for folds, can be prevented by increase of pressing areas for preventing wrinkles at both sides of the drawn portion.

    摘要: An offset-shaped fin 4 can be continuously processed by roll molding by a method involving a first step of bending a flat sheet-like material 40A into a concavo-convex shape by a pair of first rollers 5, 5′ to form a corrugate sheet 40B; a second step of cutting slopes of the concavo-convex ridges of the corrugate sheet by a pair of second rollers; and a third step of bending the offset portion, offset and cut in the second step, by a pair of third rollers. A pitch-changing method of offset-shaped fins involves a step of supplying offset-shaped fins between at least one pair of pitch-changing rollers rotating while meshing with the other so that at least one pair of pitch-changing rollers clamp the offset-shaped fins between them, allow them to pass through said pitch-changing rollers and change their pitch.

    摘要: A method of producing a flat tube T by bending a band-like material M to be worked, wherein the material M to be worked is pre-bent to form a pre-formed groove Md in the material M along the longitudinal center axis thereof. Thereafter, the material M to be worked is gradually moved so that both edge portions of the material M to be worked in the lengthwise direction thereof gradually approach each other with the pre-formed groove Md as a center to form a tubular shape.

    摘要: Multiple movable die portions (press punches) are respectively opposing to multiple fixed die portions (block members). Each of the press punches is sequentially pushed down with a predetermined time difference to the corresponding block member to continuously carry out press work to a material inserted into a press-work area between the press punches and the block members. A clearance is formed between a forward end of the press punch and a forward end of the block member at a position shortly before a press-work operating position in order to control a pulling force of the material, so that a shape distortion can be avoided.

The inner rim (21) has a small curvature region (102). The small curvature region (102) is inclined to a flat plate portion (11), and is defined by a radius larger than a difference between a half of a thickness of the flat tube (10) and a thickness of the outer rim (22). The small curvature region (102) is not beyond a center line (C1) in a thickness of the flat tube (10). The outer rim (22) extends beyond the center line (C1). The outer rim (22) has an end face (22a) placed on the small curvature region (102). The flat tube (10) has flared portions (15, 16) expanded at insertion holes (54).

    摘要: A tube for a heat exchanger has a tube member and a fin inserted in the tube member. The tube member has a first wall having a first end portion and a second wall having a second end portion. The second end portion of the second wall is folded over the first end portion of the first wall. Also, an end of the fin is held between the first end portion and the second end portion of the tube member. Further, the end of the fin has a bent portion at an end of the first end portion within the folded second end portion. The bent portion of the fin is engaged with the first end portion of the tube member for positioning the fin with respect to the tube member.

    摘要: A method for forming a plurality of slits in a tube includes first, forming a plurality of grooves in the pipe by operating a grooving punch along the length of each of the slits to be made. Then, each slit is formed in the pipe by operating a hole-making punch. The punch has ends at an acute angle and the punch is recessed from the ends toward the center thereof. In view of the fact that each groove is formed beforehand in the surface of the pipe and that the corresponding slit is made while moving the hole-making punch slowly from the ends, a large load is not exerted on the pipe and therefore the pipe is not crushed, burrs are not generated and the cutting chip is removed.
