Problems solved by technology

[0004] In the production of workpieces which are processed by means of a forging hammer by means of several successive forgings (Schmiedeschlag), the greater challenge is to adapt the individual forgings to the forging process in such a way that it is specific to the forming result, ie from the corresponding previous forging process. Reduction in workpiece thickness caused by forging

Embodiment Construction

[0075] exist figure 1 A schematic diagram shows a forging hammer 1 configured as a linear hammer 1a. The linear hammer 1 a includes a frame 13 and a rotor 9 . The rotor 9 comprises a striker 4 and a secondary part 35 which is connected in a non-displaceable manner to the lateral surface 20 of the striker 4 in the direction of the travel axis VA9 of the rotor 9 . for Figures 1 to 3 For clarity of illustration, not all cutaway components are shown.

[0076] The frame 13 includes an anvil 2 and a head part 3 connected to the anvil 2 . For the complete construction of the linear motor 10 , the linear hammer 1 a includes a stator 8 with a primary part 36 . By means of the linear motor 10, the rotor 9 can be moved from the lower position I indicated by the dashed line along the travel axis VA9 of the rotor 9 to the figure 1 in the upper position II shown in and can be driven in reverse.

[0077] The stator 8 is connected to the head part 3 , wherein the head part 3 is designe...

Abstract

The invention relates to a hammer and a method for tracking motion of a hammer head. The hammer (1) is used for machining a workpiece (W). The hammer comprises a frame (13) and the hammer head (4). The frame (13) comprises an anvil block (2) and a head component (3). The hammer (1) comprises at least two stroke measuring systems (2301,2302). The stroke measuring systems (2301,2302) are provided with vertical positions (2301-1,2302-1) for measuring the hammer head (1) along a driving axis (VA9), wherein the position (2301-1) of the hammer head (4) in the hammer (1), which is occupied by the hammer head (4) in the frame (13), can be detected through a first stroke measuring system (2301). Furthermore the position (2302-2) of the hammer head (4) in the hammer (1), which is occupied by the hammer head (4) in the frame (13), can be detected through a second stroke measuring system (2302).

Description

technical field [0001] The invention relates to a forging hammer according to claim 1 or the preamble to claim 6 and a method for tracking the movement of a striker of a forging hammer. Background technique [0002] Forging hammers for use in industry, for example in die forging or die forging, are sufficiently known from the prior art. A detailed introduction to this field of expertise can be found in the document "Handbuch Umformtechnik" (Eckhart Doege, Bernd-Arno Behrens, Springer Verlag, 2nd edition, 2010, p. 719 et seq.), to which reference is hereby made. [0003] Furthermore, a forging hammer configured as a linear hammer is known from DE 10 2008 064 228 A1. The known linear hammer includes an adjusting unit, by means of which a changing position of a secondary part of the linear hammer that moves with the hammer head is tracked by means of a position sensor. [0004] In the production of workpieces which are processed by means of a forging hammer by means of severa...
