Embodiment Construction

[0017] exist Figures 1 to 3 shows a double edge trimmer according to the invention in different positions. The double edge trimmer has a stationary lower knife and a liftably driven upper knife (not shown here), wherein the upper knife is arranged on an upper knife slide 12 guided by means of a slide guide 10 . For the guidance of the slider guide 10 , a first eccentric shaft 14 and a second eccentric shaft 16 are arranged on the slider guide 10 , wherein the first eccentric shaft 14 and the second eccentric shaft 16 are connected to each other via a synchronization means 18 . The first eccentric shaft 14 and the second eccentric shaft 16 can thereby execute a movement synchronous with one another and thus bring about a horizontal or transverse parallel adjustment of the upper knife slide 12 for adjusting the tool play, in particular the tool play of the upper knife.

[0018] The synchronizing means 18 are designed in the form of rigid rods, which are mounted rotatably on th...

Abstract

The invention relates to double trimming shears having a stationary bottom knife and a driven top knife which can be raised and lowered, wherein the top knife is arranged on a top knife carriage (12) guided by means of a carriage guide (10), wherein a first eccentric shaft (14) and a second eccentric shaft (16) on the carriage guide (10) is provided in order to guide the carriage guide (10) if an inclined position of the top knife carriage is to be prevented. This is achieved in that the first eccentric shaft (14) and the second eccentric shaft (16) are interconnected via a synchronization means (18).

Description

technical field [0001] The invention relates to a double edge trimmer (Doppelbesaeumschere) with a fixed lower knife and a liftably driven upper knife, wherein the upper knife is arranged on an upper knife slide guided by means of a slide guide (Schlittenführung). At the block, wherein, for the guidance of the slider guide, a first eccentric shaft and a second eccentric shaft are arranged at the slider guide. Background technique [0002] Double edge trimmers are often used to trim sheet metal to its final width. Double edge trimmers are mostly driven via a crankshaft, which however cannot be variably adjusted with respect to the cutting movement. The slide guides of the upper knife slide are respectively fixed on the eccentric shaft in the upper region and in the lower region. In the lower region, the eccentric shaft is usually mounted via a control rod. The guide of the upper knife slide can be adjusted in height by means of an eccentric shaft arranged in the upper regi...
