A reciprocating die roll forming machine for forming a pattern such as a thread form on the outer surface of a cylindrical blank includes at least one set of reciprocating dies operating upon the blank which rotates in place. The machine includes a slide and bearing combination to support the dies belt driven by a servo-motor controlled by a central processing unit. Mechanism is provided to deliver and position a blank for engagement by the dies. In one form, the machine includes multiple die sets to produce multiple parts during one die reciprocation cycle. In another form, the machine employs separate drive mechanisms to independently drive each die of a set.

Roll forming machine with reciprocating dies

A multi-station, reciprocating die pattern forming machine (), including a pair of parallel reciprocal slide members () with spaced pairs of pattern forming dies () thereon reciprocal between an insert position and an eject position. Drive mechanism () reciprocates the die pairs alternately between the insert position and eject position. Mechanism delivers and positions a pattern receiving blank () to a pair of dies when in the insert position. Axial translation of the dies causes the dies to rotate the blank at a center of process and impart a pattern upon the blank. Servo-motors on blank positioning mechanism provide feedback recognition of the position of the blanks during processing. The invention also relates to a method of patterning blanks.

Multi-station reciprocating die roll forming machine

A method is disclosed for roll forming the face pattern onto a pattern forming die having a pattern receiving face, using an initial, and subsequent, pattern forming tool, each with a generally cylindrical pattern defining surface, by relatively and sequentially reciprocating and rotating the pattern defining surfaces and the pattern receiving face while engaging them and urging them to impress the pattern of the pattern defining surfaces into the pattern receiving face of the forming die blank. An apparatus for performing the process is disclosed which includes a platen for the pattern forming die, initial and subsequent pattern forming tools each having a generally cylindrical pattern defining surface, a drive mechanism for relatively and sequentially reciprocating and rotating the pattern defining surfaces and the pattern receiving face of the forming die blank, and relative movement mechanism for engaging the surfaces to impress the pattern of the pattern defining surfaces of the pattern forming tools into the pattern receiving face of the forming die blank.

Method and apparatus for cold forming thread rolling dies

A push/push latch designed to operate in high and low g-force situations, which may be mounted horizontally or vertically. The latch includes a latch body, a track, a housing surrounding the track and latch body, a follower with a pin that moves in the track to actuate the push/push latch. The invention also includes a hammer that repositions when a g-force is applied to the latch to stop the movement of the track body thus preventing the latch from opening during a g-force situation such as a vehicle crash. The hammer may be connected to the housing or to the latch body.

Push/push latch

The present technique provides a stabilizer system comprising a plurality of piston cylinder assemblies, which have multiple interconnected chambers to provide cross compensation between suspension members coupled to those piston cylinder assemblies. The piston cylinder assemblies may have two or more chambers separated by pistons, which move in response to a load imposed on the suspension member coupled to that piston cylinder assembly. As the piston moves in response to movement of the corresponding suspension member, a fluid pressure is transmitted to another suspension member to distribute the load between the two suspension members.

Hydraulically compensated stabilizer system

A measuring device (10) and method for duplicating an irregular shape (200) onto a sheet of material (300) by employing the device (10) in combination with a sheet of paper (100) and a conventional marking implement; to form traced lines (101) on the sheet of paper (100) in response to measurements taken from the irregular shape (200); transferring the sheet of paper (100) to the sheet of material (300); using the traced lines (101) and measuring device (10) to make marks (301) on the sheet of material (300); and, then severing the sheet of material (300) in line segments between adjacent marks (301).
