Abstract: A cone crusher, including a supporting device being arranged inside a cavity of a main shaft of the crusher. The supporting device is arranged to support a crushing head, and to be vertically displaceable for adjusting the width of a crushing gap. The supporting device has an upper portion enclosed by the crushing head, the upper portion being arranged to provide support to the crushing head. A lower portion extends downwards within the cavity of the main shaft, wherein the upper portion and the lower portion have different outer dimensions as defined transverse to the shaft axis. A pressure-active surface is formed at a transition between the upper portion and the lower portion so as to form a variable-volume compression chamber within the cavity below the pressure-active surface.

Abstract: A domer station having a domer assembly, a housing assembly, and a stacked piston assembly is provided. The domer assembly is movably disposed within a domer body passage located in the housing assembly and structured to move between a forward, first position and a retracted, second position. The stacked piston assembly includes a plurality of pistons, preferably three pistons, disposed in series and a pressure supply. The pistons are disposed behind the domer in pressure chambers. The pistons have a constant pressure applied thereto and are biased towards the domer. The pistons are, however, each restrained by a stop and do not contact, or operatively engage, the domer when the domer is in the domer first position.

Abstract: To reduce warping of vertical wall portions without causing buckling occurring in a component shape not having a flange portion. A punch and a pad sandwiching a top sheet portion therebetween in the sheet thickness direction, bending blades for bend-forming the vertical wall portions, and stoppers facing the bending blades in the press direction and constraining end portions of a material to be machined are provided. The punch is supported by a first cushion component elastically expandable and contractible in the press direction. The bending blades each have an upper die component and a lower die component disposed facing each other in the press direction with an interval (D) equal to or larger than a set compression amount and a second cushion component interposed between the upper die component and the lower die component, maintaining the interval (D), and contractible in the press direction at a predetermined pressure or more.

Abstract: A coiled material passing device is usable to pass a coiled material played out by an uncoiler to a leveler feeder configured to correct any winding curl of the coiled material. The coiled material passing device includes a clamper configured to clamp a starting end of the coiled material played out from the uncoiler, a moving body configured to support the clamper, the moving body being movable between the uncoiler and the leveler feeder, and a first driver configured to move the moving body.

Abstract: A conduit offset bender preferably includes an upper die, a lower die, a first guide plate, a second guide plate, a force transfer plate, two compression springs and an actuation device. The upper die includes an upper die base, a first pair of lugs, a second pair of lugs, a first boss flange and a second boss flange. The lower die includes a lower die base, two first lower boss flanges and two second lower boss flanges. Larger and smaller offset grooves are formed in the upper and lower dies. The two compression springs are retained in spring counterbores formed in the upper and lower boss flanges. A bottom of the first and second guide plates are attached to the lower die base. The actuation device includes a first handle plate, a second handle plate, a pressure roller, a cam roller, a pivot pin and a retention pin.

Abstract: To reduce warping of vertical wall portions without causing buckling during pressing. Press-forming into a hat cross-sectional shape having one linear vertical wall portion and the other curved vertical wall portion and not having a flange portion is performed. A punch and a pad sandwiching a top sheet portion therebetween, bending blades, and stoppers are provided. The punch is supported by a first cushion component. The bending blades each have an upper die component and a lower die component disposed facing each other in the press direction with an interval (D) equal to a set compression amount in the range of 2% or more and 6% or less of the heights of the vertical wall portions and a second cushion component interposed between the upper die component and the lower die component, maintaining the interval (D), and contractible in the press direction.

Abstract: The disclosure discloses a wheel rim straightening device. The wheel rim straightening device includes a lifting platform; the lifting platform is symmetrically provided with a left horizontal sliding table and a right horizontal sliding table; the left horizontal sliding table and the right horizontal sliding table are each provided with a vertical sliding table; and the two vertical sliding tables are provided with an inner pressure head which extends outwardly and corresponds to an outer pressure head, and a first runout detecting gauge corresponding to a second runout detecting gauge.

Abstract: A method for manufacturing a press formed product is disclosed. The method for manufacturing a press formed product includes: when a metal sheet is press formed to manufacture a product having a product shape of a hat-shaped cross-section, in which a top plate part and a flange part are continuous in a width direction through a side wall part and the top plate part and the flange part curve convexly or concavely toward the top plate part along a longitudinal direction, a first step of manufacturing an intermediate component by press forming into a component shape having a hat-shaped cross-section, in which a curve of each of the top plate part and the flange part along the longitudinal direction has a second curvature radius smaller than a curvature radius in the product shape; and a second step of press forming the intermediate component into the product shape.

Abstract: The present invention is an imprint device for imprinting a unique identification mark on a surface of an object with imprinting particles of different sizes that increase uniqueness and without the need for electric power. The imprint device includes a vertical member, a hammer member, a trigger assembly, a charging unit, a barrel and at least one pocket. In the operative configuration, a trigger of trigger assembly is activated such that hammer member impacts a cartridge filled with at least one munition of imprinting particles and releases imprinting particles. The imprinting particles travel through the barrel where acceleration is increased and impact on surface is made to form microcraters and unique identification marks. The imprinting particles can be of same size, material and shape or they can be of different sizes, material and shapes or the combination thereof for increasing uniqueness.

Abstract: A knife with a serrated cutting edge may include a plate having a leading edge forming a plurality of teeth seats arranged in a stepped configuration, with each of the plurality of teeth seats. The knife may also include a plurality of elongate cutting elements each affixed to one of the teeth seats formed by the leading edge. The cutting elements may form a portion of the serrated cutting edge, and each may have a top surface and a bottom surface. The cutting edge may be on the top surface and the bottom surface may be affixed to one of the teeth seats. The serrated cutting edge has a plurality of primary serrations and a plurality of secondary serrations, with each of the cutting elements forming at least one of the primary serrations and at least one of the secondary serrations.

Abstract: An agricultural baler includes: a chassis; a coupler configured for connecting to a power source; a bale forming chamber including an apron assembly; an apron tensioning system that controls a baling pressure exerted on a bale forming in the bale forming chamber; a bale release that releases a fully formed bale; and a controller operatively coupled to the apron tensioning system and the bale release. The controller is configured to: set a release size of the fully formed bale; receive a PTO power consumption signal or an available power signal from a tractor controller; determine a maximum available power based on the received signal; compare the maximum available power to a threshold power; and output a control signal to the apron tensioning system to decrease the baling pressure without changing the release size when the maximum available power is at a predetermined power value, relative to the threshold power.
