Definitions
- the above invention relates to a forming and Punching tool that with an additional device for the Perform punching work in a press is.
- tools use, which usually consist of two components.
- One component of the tool is stationary on the press table attached while the second component of the tool connected to the up and down movable slide of the press is.
- the punching or bending tool is usually done by Drive means operates on the movable component are arranged.
- Hydraulically actuatable devices are also known become, which during a downward movement of the movable component are operable and during one upward return movement of the component remain inactive.
- an additional device that has these features, is it possible to add an additional forming or Punching tool to create that optionally during one downward movement or during a downward movement upward movement of the drive means of the Tool operated, or can not be used.
- the forming or stamping tool is usually used by an upper component 1 formed with the movable Carriage (not shown) is connected to a press.
- the carriage of the press leads an up and down Movement in the form of an alternating downwards or downwards above stroke.
- the tool also consists of a stationary arrangement Component (not shown) that in a known manner on fixed table of the press is arranged.
- the fixed one Component or the movable component of the tool Assign additional devices with which e.g. simple additional punching or punching operations can be carried out, with these additional devices from the Outside of the multi-part tool on the in the tool existing and widely deformed workpiece.
- the device according to the invention relates to a Additional device, which is marked overall with 2.
- the additional device 2 consists of a tubular Recording 3, the desired location on the outside of the fixed component or the movable component of the tool or in certain cases on the Press table itself can be arranged.
- a stamp or a Arranged tool holder 4 Inside the receptacle 3 is a stamp or a Arranged tool holder 4, which in a known manner Forming or punching tools can be equipped.
- a return spring 5 Inside the tool holder 4 is a return spring 5 arranged, which has the task of the tool holder 4th to keep in a rest position, as shown in Figure 1.
- the back part of the tool holder 4 has one Continuous formed like a slot Recess or opening 6.
- This recess 6 is with the aid of a cross pin 7, a drive lever 8 pivoted.
- the drive lever 8 has on his free end of a rotatable contact roller 9.
- the lever 8 a rounded section 10 to a one-sided creating acting joint; the lever 8 has the Possibility, only in one with the arrow (f) to swivel the marked direction during one Swivel movement in the opposite direction is omitted as this is due to the inner wall of the Tool holder 4 is prevented.
- the receptacle 3 has an opening 11.
- the Opening 11 is provided to the lever 8 and the Contact roller 9 a free pivoting movement in the direction of Arrow (f).
- the movable component 1 of the tool is a protruding arm 12 connected, and this arm can while the movement of the displaceable component 1 in a chamber or recess 13 enter into the receptacle is provided opposite the tool holder 4.
- the tool holder projects into this chamber 13 when the tool is at rest 4 a drive roller 9.
- the cam 14 advantageously has the shape of a Triangular, but there are other cam shapes for control the displacement movement of the receptacle 4 is conceivable.
- the additional device 2 can be compared to the fixed part of the tool (not shown), such as shown in Figure 1, i.e. with the curve-like rounding 10 of the lever 8 and the opening 11 of the tubular bearing 3 on the movable component of the tool 1 directed.
- FIG. 9 and 10 is the average Additional device 2 for performing additional Processing operations with the help of the movable Component 1 of the tool shown.
- everyone is there Components of the additional device 2 identical to those previously described parts with the only difference that the Headpiece of the stamp 4 forms a real piston that inside a chamber 20 of a hydraulic cylinder 21 is arranged.
- the hydraulic cylinder 21 has one Opening 22 for the entry or exit of a hydraulic fluids, e.g. Oil on.
- the output 22 of the cylinder 21 is e.g. with the sledge a tool holder that is hydraulically driven, connectable.
- the additional device 2 is 180 ° around the own longitudinal axis has been rotated, i.e. also opposite the moving part of the tool.
- FIGS. 9-10 does not differ from that described so far Tool 2 is additional in this embodiment provided that the stamp or tool holder 4 is designed as a piston which is in a cylinder 21st is arranged, which is connected to the bearing 3.
- the cylinder 21 takes a hydraulic one in the chamber 20 Fluid on, via an opening 22 a hydraulic actuable tool (not shown) can be.
