A punch tool with an expanded portion, a movable punch provided on a fixed punch so as to be able to move up and down in a direction along an inclined portion, and an interlocking member configured to interlock with a relative ascending and descending motion of the movable punch with respect to the fixed punch. The punch tool with an expanded portion is provided with an operation member provided on the fixed punch so as to be movable in the lateral direction, configured to move in the lateral direction by means of a moving motion of an external operation member, and including an abutting element capable of being abutted with the interlocking member, and an urging member configured to urge the operation member toward the inside in the lateral direction such that the abutting element is abutted with the interlocking member.

A shaving head that doubles as breaking mechanism to break a safety razor blade into two pieces to form a 2-blade shaving razor. The shaving head includes a front component having a retention guide, a first position stop and a second position stop at a distance offset from the first position stop. The shaving head further includes a back component having a blade slot configured to receive a first blade portion and a second blade portion formed from breaking a double-edge safety razor blade such that the first blade portion has a different width compared to the second blade portion. The retention guide is configured to retain the first blade portion and the second blade portion in the blade slot responsive to the retention guide being at least partially inserted into the blade slot. The sharp shaving edges once installed form a shaving angle between 5 and 30 degrees, where the shaving angle is determined by where the blade is broken.

A press brake assembly configured to bend a workpiece that includes an upper beam configured to hold an upper punch and a lower beam configured to hold a lower die. A safety latch is disposed within a safety latch cavity of the upper punch, and the upper punch is partially housed within a first cavity of the upper beam. A biasing member is also disposed within the safety latch cavity. A pin extends from a lateral side of the upper punch through the safety latch, and the safety latch is configured to rotate about the pin. The safety latch includes a cam configured to engage the upper beam within a second cavity of the upper beam. The biasing member is configured to bias the cam in a forward direction towards the upper beam cavity to prevent the upper punch from disengaging the upper beam.

A tool for a bending press is described, the tool comprising a safety element to prevent the tool from accidentally falling from a pressing table of the press.

A production installation for producing workpieces from sheet metal by reshaping includes a bending machine, a support table defining a support plane, and a manipulation device having a support arrangement and a holding arrangement. The holding arrangement has interacting upper and lower holding units. The support arrangement has a separate upper support unit and a separate lower support unit, wherein the upper holding unit is arranged on the upper support unit, and the lower holding unit is arranged on the lower support unit. In an open insertion position of the manipulation device for the sheet metal to be accommodated therein, and in a loading region in front of the bending machine, the upper support unit, together with the upper holding unit, is arranged entirely above the support plane, and the lower support unit, together with the lower holding unit, is arranged entirely below the support plane.

A machine integrated positioning system shows an operator where to place a raw part in the press brake or other machinery. Further, the operator is informed if the dimensions associated with the raw part are, or are not, correct to produce the planned finished part. The operator is visually shown how the raw part is to be oriented. The operator is informed if the raw part is right-side-up, along with other pre-final placement information. If these and other conditions are not met, the machine integrated positioning system may prevent the press brake and other machinery from cycling.

The invention relates to a workpiece stop, a signal output device for outputting a signal directly perceivable to an operator of a workpiece processing machine from his/her working position, an imaging device for generating at least one image of the interior of a workpiece processing machine, a device for monitoring a processing position of a workpiece, a work-piece processing machine, a use of a device for monitoring a processing position of a work-piece, a use of a workpiece processing machine and a method for processing a workpiece in a workpiece processing machine. These devices and method promote safe and efficient operation of a workpiece processing machine.

A press machine comprises a moveable press ram, an actuator, a first motor system, a second motor system, and a belt system. The moveable press ram holds a tool that forms a part. The actuator linearly moves the moveable press ram by use of a male-female thread mechanism. The actuator includes an actuator sprocket coupled to the male-female thread mechanism. The first motor system produces a high-force linear movement condition to the press ram, and includes a clutch coupled to a first motor and a first motor sprocket coupled to the clutch. The second motor system produces a high-speed linear movement condition to the press ram. The belt system couples the actuator sprocket, the first motor sprocket, and the second motor sprocket. The clutch allows the first motor to partially or fully disengage from rotational movement of the first sprocket when the belt is being driven by the second motor.

An adapter tool having an attachment section, a body, and a connector. The body is attached to the attachment section and has a punch seat and a clamping space. The connector has a clamping plate that can rotate in relation to the body. The clamping place has an engagement member configured to engage a punch insert. The connector is configured to move between a first position and a second position. In the first position, the engagement member is a first distance from the punch seat. In the second position, at least a portion of the clamping plate resides within the clamping plate space, and the engagement member is located a second distance from the punch seat the connector to the body. The biasing member biases the connector to the first position. The first distance is less than the second distance.
