  • Patent number: 7445439
    Abstract: A clamping unit for an injection molding machine includes a fixed platen, a support platen, and a moving platen which is arranged between the fixed platen and the support platen for back and forth movement. An opening and closing mechanism constructed as crank drive having at least one crank disk is provided to effect a back and forth movement of the moving platen in relation to the support platen, with the crank disk rotatable by a drive mechanism. A first connecting rod links the crank disk to the support platen, and a second connecting rod links the crank disk to the moving platen, wherein at least one of the first and second connecting rods is articulated in eccentric relationship to the crank disk. A pulling means extends between the support platen and the fixed platen to allow a buildup of a clamping force between the fixed platen and the moving platen.

  • Publication number: 20080250948
    Abstract: A hard disk destruction apparatus is presented having a penetrating point that is manually pressed against a hard disk. The point has an angled tip designed to penetrate the hard disk casing and deform the hard disk platters within. The manual pressing avoids the use of any electrical power or other fuel. In one described embodiment, a mechanical arbor press provides the necessary force. A transparent safety shield surrounds the hard disk during destruction. A restraint prevents upward movement of the hard disk when the point is extracted.

  • Patent number: 7360482
    Abstract: This invention reveals a crank roller paper cutting device, which comprises a base, a supporter, a handle part, a master roller, a slave roller, and a group of speed-reducing gears. Via the group of speed-reducing gears, handle part correlates to the master roller and slave roller at one terminal, both of the master roller and slave roller are captured by the open bores therewith on the supporter. While the other ends of master roller and slave roller are suspended in the air, where a removable positioning block is attached. Upon the above said positioning block, there are two open bores or blink holes in correspondence to the master roller and slave roller respectively. Around the master roller and slave roller are many removable regulating cylinders, or one regulating cylinder in different thickness. This crank roller paper cutting device is reasonable in design, easy to use and safe in operation for a wide range of applications, particularly valuable for kindergarten enlightenment education.

  • Patent number: 7357073
    Abstract: A press drive unit and press drive method are provided which decrease the cycle time of a press to improve its productivity, enable use of small-sized, inexpensive presses and provide improved product quality. To this end, the press drive unit comprises a drive shaft coupled to a slide through a specified power transmission mechanism; a first drive system for rotationally driving a flywheel with a main motor and driving the drive shaft through a clutch disposed between the flywheel and the drive shaft; and a second drive system for driving the drive shaft at variable speed with a sub motor. Driving is carried out with the first and second drive systems in a formation zone, and driving is carried out with the second drive system alone in a non-formation zone.

  • Patent number: 7331281
    Abstract: A press has an upper traverse, a lower traverse below the upper traverse, and vertical frame elements extending between the traverse, fixing same together against relative movement, and forming a rigid frame with the upper traverse and lower traverse. A central traverse is vertically reciprocal on the elements between the upper and lower traverses. A workpiece is fed horizontally through the press between the upper traverse and the central traverse. A stationary support is provided adjacent the frame, and the frame is supported for at least limited vertical movement relative to the support. A drive connected between the support, the frame, and the central traverse vertically reciprocates the frame and the central traverse relative to the support.

  • Patent number: 7234337
    Abstract: A punch press that provides an arrangement of a motor and a crank mechanism so that the motor does not project far from the side of a frame. The punch press includes a servo motor, a ram which drives a press tool, a crank mechanism which converts a rotating motion transmitted to a crank shaft into an elevating and lowering operation of the ram, and a drive transmitting mechanism which transmits rotation of the servo motor to the crank shaft while reducing rotation speed. The servo motor is next to the crank mechanism and its rotating axis is parallel to the axis of the crank shaft. The drive transmitting mechanism includes servo motor side gears joined to respective output shafts of the servo motor. The servo motor side gears respectively engage, directly or via intermediate gears, with crank side gears joined to the crank shaft.

  • Patent number: 7185585
    Abstract: An apparatus for crushing containers includes a die defining an opening, a punch, and a system for displacing the die and punch relative to each other. The punch may be fixed and the die may be moved from a first position spaced apart from the punch such that a container to be crushed can be placed between the punch and die and a second position in which the punch extends into the die opening to define an annular gap between the punch and die opening. The arrangement is such that a container crushed between the die and punch as a result of displacement of the die to the second position is at least in part forced into and deformed within the annular gap.

  • Patent number: 7162908
    Abstract: The invention deals with the field of bending presses, and, more precisely, deals with a device for handling the upper table moving along guiding pillars and carrying the punch. For every table guiding pillar, the device provides for a main lever (10) hinged in a point that is substantially axial with its related guiding pillar and whose driving arm (10a) is hinged to means sliding along a rod hinged to the upper table. The lever resisting arm (10b), whose length is approximately 8–10 cm shorter that the driving arm length, rotates a crank (12) connected through an eccentric (13) or a connection rod to a connecting rod (14) that transmits the translating motion to the upper table.

  • Patent number: 7100499
    Abstract: A strap pressing device for a strap packing apparatus includes a strap presser, an eccentric shaft, and a spring. The eccentric shaft consists of a first shaft and a second shaft eccentrically connected to the first shaft and received in an oval hole of the strap presser. The first shaft is pivotally connected to a side of the base. A spring is fitted around the second shaft in the oval hole, so the strap presser may be pressed down to press a strap closely contact the upper surface of the base, and also moved bias by movement of the second shaft when the first shaft is moved by a lever so that the strap presser may be moved bias to rise up quickly to leave the upper surface of the base so as to prevent a curved bottom surface of the strap presser from frictionally sliding on the strap to give scar on it.

  • Patent number: 7062949
    Abstract: A metal forming press has an oscillating beam driven at its center by a connecting rod connected to a throw on a crankshaft. The upper end of the beam is pivoted to a link which drives a ram. The lower end of the beam pivots about a rotating eccentric shaft having an eccentric lobe. As the beam oscillates, these eccentricities cause the lower pivot to move toward and away from the ram so that the arc of the upper pivot approximates a straight line.

A motor driven link press comprises a link mechanism 1 that converts a rotating operation into a linear operation and a ram 6 that elevates and lowers for press working on the basis of this linear operation. The link mechanism 1 comprises a crank member 2 having a crank shaft 3 and an eccentric shaft portion 4, a pivoting link 5, a connecting rod 7, and a restraining link 8. The pivoting link 5 has a first to third connecting portions P1 to P3 and is connected to the eccentric shaft portion 4 of the crank member 2 using the connecting portion P1. The connecting rod 7 is connected to the second connecting portion P2 and the ram 6.
