Definitions

the present invention relates to a pressure limiting device for a tool with a stamp and die.
So-called clips are used in devices for tying sausages, which are deformed by means of a stamp and a die so that the end of the sausage is closed. Due to the large number of sausages, different clips are used, which differ in type and size. This means that the punches and dies on the binding machines have to be changed, whereby the working stroke between the punches and dies often has to be changed as well. This leads to incorrect manipulation, which can lead to destruction of the binding machine, particularly when changing from a small to a larger working stroke.
the aim of the invention is to provide a device which does not have the disadvantage and with which the tool is protected.
the device shown in FIG. 1 is mounted in a tool holder 1 of a machine for tying sausages.
the device in question essentially consists of a cylindrical plunger 2 and a pressure accumulator 3.
the plunger 2 is mounted in a recess which is dimensioned such that a chamber 4 is present between the piston head and the bottom of the recess.
the plunger 2 is held in the recess by an end plate 5 and is provided with a sealing ring 6 which seals the chamber 4 to the outside.
the plunger 2 also has a cylindrical projection 7 which protrudes from the piston head and protrudes through a bore in the tool holder.
a threaded portion on which a ring nut 9 is screwed to adjust the volume of the chamber 4.
a pointer 9 is mounted on the extension 7.
a scale 10 is engraved on the tool carrier 1 for adjustment.
the plunger 2 has a second cylindrical extension 11 which projects from the other end face and projects through an end plate 12 which holds the plunger 2 in the recess.
a stamp 13 is mounted on the second attachment 11.
the pressure accumulator 3 has a cylindrical housing, consisting of a lower part 15 which is open on one side and has a bore 16 in the other end wall (FIG. 2) and an end cap 17 which can be screwed onto the open end of the lower part 15.
a storage piston 18 is arranged axially displaceably in the housing and divides the space in the housing into a liquid space 19 and a gas space 20.
a valve piston 21 is displaceably arranged in the liquid space 19 in order to open or close the opening 16 in the lower part 15.
a spring 22 is arranged in the liquid space 19 in order to press the valve piston 21 against the opening 16, while a further spring 23 is arranged in the gas space 20 in order to bias the storage piston 18 against the liquid space 19.
the pressure accumulator is also provided with a preliminary stroke valve 24.
the pressure accumulator 3 is mounted in a recess in the tool holder 1 so that the opening 16 in the lower part 15 is aligned with a bore 26 which opens into the chamber 4.
the opening 16 in the lower housing part 15 has a seat surface which cooperates with a first seat surface on a tubular extension 25 on the valve piston 21 in order to open or close the opening 16 on the pressure accumulator.
the extension 25 on the valve piston 21 also has a second seat which interacts with the pre-stroke valve body 24.
the working stroke of the tool must be adapted to the clip height.
the following description of the function of the device now assumes that the adaptation has not been carried out and that the tool carries out a small working stroke, although a larger working stroke is required.
a desired pressure value for the plunger 2 can be determined by designing the cross section of the valve body 25 of the valve piston 21, including the valve body of the pilot valve 24 with reference to the cross section of the plunger 2. If the actual value in the chamber 4 exceeds this setpoint, the valve piston 21 moved, and thus the chamber 6 is relieved via the bore 26. As a result, the plunger 2 is displaced, whereby the working stroke of the tool is adjusted in the sense of an extension. At the same time, the machine can be switched off and an acoustic or visual signal can be emitted.
the pre-stroke valve is actuated.
the plunger 2 can be adjusted without pressure.
the liquid is then fed back through the pressure accumulator 3.
