Crimping tool with power component, and system and method for connection of workpieces

Abstract

The invention relates to a crimping tool (2) for connection of workpieces with pivot elements (4a, 4b) and at least one force element (16), wherein the pivot elements (4a, 4b) in each case (8a, 8b) have a pressing portion, wherein the pressing portions ( 8a, 8b) form an interference region (12), wherein the pivot elements (4a, 4b) are mutually pivotable between an open and a closed position of the pressing portion (12), wherein by the movement direction of the respective pressing portions (8a, 8b) at a Close the pressing portion (12) a pressing direction of movement is defined and wherein the force element (16) when activated, a force along a force axis (20) exerts. Furthermore, the invention relates to a system for connection of workpieces with an inventive crimping tool (2) and with a press ring (42), wherein the pressing ring (42) is pivotable between an open and a closed position, and wherein the pressing ring (42) includes a joining portion (44) for the pressing region (12) of the pressing tool (2).

Description

technical field [0001] The invention relates to a pressing tool for connecting a plurality of workpieces with a rotating part and at least one power part, wherein the rotating parts each have a pressing section, wherein the pressing section forms a pressing area, wherein the rotating part Can be rotated relative to each other between an open position and a closed position of the squeeze zone, wherein the squeeze movement direction is defined by the direction of movement of the individual squeeze segments when the squeeze zone is closed, and wherein the power component is activated The force is applied along the force axis. Furthermore, the invention relates to a system for joining a plurality of workpieces, the system having a pressing tool according to the invention and a pressing ring, wherein the pressing ring is rotatable between an open position and a closed position, and wherein the The extrusion ring has a connecting region for the extrusion region of the extrusion too...

AI Technical Summary

Problems solved by technology

[0009] However, such an arrangement of power components hinders the user's vision on the workpiece to be extruded

Furthermore, since the power part has to be attached tangentially to the extrusion ring, it is difficult to manually operate such an extrusion tool especially in very tight space conditions, for example in the case of pipes running closely adjacent to each other Down

Squeezing tools with such a structure are moreover often difficult to handle, since use involves the use of a large number of handles, are not intuitive and must be held by the user by hand during or after the squeezing process

There is also the risk of the press tool being released from the workpiece and falling down after the power unit has stopped
