A metal band as an insert for trim strips, sealing strips, or edge protection strips, in particular for motor vehicles, wherein the surface is profiled at at least one flat side of the band to increase the adhesion between the metal band and a plastic or rubber coating. These metal bands can also be designed with a plurality of openings following one another in the longitudinal direction of the band, in particular cut and roll-stretched or punched slots.

A lock jamb punching tool includes a face member having a die aperture, a rabbet member protruding normal to the face member, a jamb area between the rabbet member and the face member, and a punch in the jamb area, the punch being slidable into the die aperture along a punch path, and an actuator to move the punch along the punch path.

A stud punch includes a housing, a motor positioned within the housing, and a planetary gear train that receives torque from the motor. The stud punch also includes a punch movable between a retracted position and an extended position, and a scotch-yoke mechanism coupled between the planetary gear train and the punch. The scotch-yoke mechanism is configured to convert torque received from the planetary gear train to a reciprocating linear force, causing the punch to move between the retracted position and the extended position.

Disclosed are pliers and related methods for punching a hole in a non-flat material without distorting the material. Such pliers may comprise a first member having a first handle and a first jaw, and a second member having a second handle and a second jaw. The first and second members are attached at a connection point to permit pivoting in response to a squeezing force on the handles. The first jaw comprises a punch tip to be received by the second jaw, where the punch tip may have an angled distal end truncating a cross-section of the punch tip. The second jaw comprises a shaped edge facing the punch tip and extending along a length of the second jaw, the shaped edge having substantially the same shape as the non-flat material and comprising an opening having substantially the same shape as the cross-section of the punch tip and to receive the tip therein.

A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

A method for manufacturing a separator that can effectively prevent warpage is provided. A method for manufacturing a separator according to an embodiment includes disposing a separator material including a flow path forming region between a first upper die and a first lower die, and pressing the separator material using the first upper die and the first lower die to thereby form a first recessed and projected shape in the flow path forming region and form a second recessed and projected shape outside the flow path forming region.

A hole punch for forming a hole in metal or other material is provided. In some embodiments, the punch comprises a first assembly that is positioned on one side of the device to be punched and a second assembly is positioned on the other side. One of the assemblies comprises a male punch and the other comprises a female die plate. In some embodiments, rotation of a bolt causes the male punch to move through the device to be punched and into the female die plate. In some embodiments, the device to be punched is a rain gutter. In some embodiments, one or both of the first and second assemblies have magnets so that the punch can be releasably assembled with the assemblies on either side of the device to be punched.

The current invention relates to a system for accurately punching holes in a profile comprising at least one clamp, slideable in a first direction, and at least one punch unit for punching holes in the profile, wherein the at least one clamp comprises a linear encoder, configured for measuring a displacement in the first direction of the at least one clamp. The invention also relates to a method for accurately punching holes in a profile comprising clamping a profile in a clamp, displacing the profile by sliding the clamp in a first direction in a punch unit, and punching at least one hole in the profile by the punch unit, wherein the displacement of the profile in the first direction is measured with a linear encoder, coupled to the clamp.

The current invention relates to a punch unit for punching holes in a profile comprising a clamp, slideable in a first direction; a first die shoe, comprising at least two punches; a second die shoe; and a transmission shaft, configured for translating a rotational movement to a linear movement and configured for displacing said punches in a stroke direction; wherein the punch unit comprises a selection control for selecting punches to be displaced by the transmission shaft in the stroke direction. The inventions also relates to a method for punching of holes in a profile with high-throughput comprising clamping a profile in a clamp of a punch unit; displacing the profile in the punch unit by sliding the clamp in a first direction; and punching at least one hole in the profile by the punch unit; wherein one or more punches of the punch unit are selected by a selection control, comprised in the punch unit, for punching said at least one hole.

A punch and die assembly for a forming assembly for forming flared openings in commercial forming steel sheeting, includes a punch. The punch has a punching element having a base portion and a working portion that extends from a face of the base portion, the working portion defining a working edge with more than two substantially evenly spaced peaks and troughs for forming an opening in the steel sheeting during a working stroke. A flaring element is mountable on the base portion of the punching element, a side of the flaring element defining an arcuate flaring surface that tapers inwardly in the direction of the working stroke. A die supports the steel sheeting, the die having a die opening with a flared die face for facing the flaring surface of the flaring element such that the opening in the steel sheeting is flared by the flaring surface of the flaring element and the die face in the working stroke.
