Abstract
In order to avoid the recoil of the striker in a hammer device (tool machine) with a striker (18) that can be accelerated to strike velocity, and a tool carrier (14) receiving the impact of said striker, the invention proposes to arrange the striker (18) between the tool carrier (14) and a corresponding mass carrier (16) which moves together with the striker (18) until the striker (18) strikes the tool carrier (14), imparting its own momentum via the striker to the tool carrier, with a supplementary mass (56) on the mass carrier (16) providing the necessary striking energy.
Claims17
A tool for cutting a wire or rod workpiece comprising:
- a striker that can be driven at a selected speed along a path from the first position to a second position to cut the workpiece;
- a mass carrier positioned on a first side of the striker and movable with the striker along a first portion of the path;
- a tool carrier positioned on a second, opposite side of the striker and movable with the striker along a second portion of the path;
- wherein
- the mass of the mass carrier has been selected to be greater than the mass of the tool carrier by an amount which, when moved at a selected speed along the first portion of the path of the striker, has a kinetic energy equal to the energy required to cut the workpiece;
- the striker and mass carrier together move along the first portion of the path while the tool carrier is stationary until the striker hits the tool carrier;
- and
- the movement of the mass carrier is stopped by transferring its kinetic energy to the tool carrier whereupon the tool carrier is driven to cut the work piece.
