Definitions
- the invention relates to a press jaw for a press tool for an unsolvable Cold connection between a fitting and a metal pipe, consisting of two, forming a press jaw halves that are rotatable in transverse to Longitudinal axis of the press jaw extending bridge parts are stored and in Press jaws in the press jaw halves each have a half-ring-shaped insert is set.
- Press jaws of this type are known, in which the half-ring-shaped insert pieces exclusively by a ball catch in the respective press jaw half be locked. This definition of the half-ring-shaped inserts gives no one hundred percent certainty that the Do not move the inserts laterally.
- Document DE-A-2 725 280 discloses a press jaw according to the preamble of claim 1.
- the invention has for its object to hold the inserts during to improve the operation of the pressing tool with simple means without this affects the easy interchangeability of these inserts.
- each bridge part has at least one tab, the with the press jaw closed or partially open in the area of the inserts extends and forms a side bracket for the inserts and at fully open press jaw releases the inserts for replacement.
- the tabs are in the immediate vicinity of the outer boundary surfaces of the press jaw halves, so that they are closed or partially open press jaw any lateral displacement of the inserts prevent.
- the press jaw 1 has two press jaw halves 2 and 3, which are about axes 4 and 5 are rotatably mounted in bridge parts 6 and 7, the bridge parts being transverse to Extend the longitudinal axis 8 of the press jaw.
- These bridge parts point to the Not shown press tool facing side equipped with a bore 9
- the press jaw halves 2 and 3 form a press jaw 11 which is of semi-annular shape Insert pieces 12 is limited, which are equipped with press edges.
- the semi-ring shaped Insert pieces 12 are in the press jaw halves 2 and 3, respectively a ball catch 13 locked so that the replacement of these inserts in can be done easily. You only need to push it out of the side of the press jaw to become.
- each bridge part 6 and 7 with a tab 14th equipped which with closed or partially open press jaw up to extends the area of the insert pieces 12 and a lateral holder for this Forms inserts.
- the tabs 14 extend for this purpose in the immediate vicinity of the outer Boundary surfaces of the press jaw halves.
- the tab 14 is advantageously formed in one piece with the respective bridge part 6 or 7. It would also be conceivable to have two webs or bolts that hold the side function take.
- the flap 14 shown in FIG. 1 and in FIG. 2 is symmetrical about the fold Arranged longitudinal axis 8 and has at the end facing the press jaw 11 an arcuate limited recess 15.
- the inserts can 12 removed without difficulty from the press jaw 11 laterally to replace them with other inserts.
- the axes of rotation 4 and 5 are formed by hollow pins 16, which have an internal thread are provided and in the fixing of the bridge parts 6 and 7 countersunk screws 17 are screwed in, the head of which is located on washers 18 supports.
