Problems solved by technology

In addition, such dies have the disadvantage that, since the die sleeve is essentially closed on the peripheral side, cleaning is difficult and can sometimes only be done by dismantling the die in a time-consuming manner

Embodiment Construction

[0026] The die consists essentially of a base body 1 with an anvil 7 formed thereon, a housing sleeve 3 and two die segments 2 , 2 a. Together with the anvil 7 , the die frames 2 , 2 a form a cavity with a cavity axis H, relative to which they are mounted in the housing sleeve 3 so as to be displaceable transversely. This travel path can be perpendicular to the hollow chamber axis H or at an angle directed upstream or downstream.

[0027] Two leaf springs 4 , 4 a are fastened laterally in the base body 1 , which act on the die brackets 2 , 2 a with a preloading force and exert a restoring force in order to push the die brackets 2 , 2 a back to their original positions. The die brackets 2 , 2 a are each provided at their lateral outer ends with a through hole 10 , 10 a into which the pins 5 , 5 a can be inserted and are then positively received in the 8 a , 8 a ′ provided in guide openings 8 , 8 ′; 8 a ′ in the housing sleeve 3 , whereby the female mold segment which performs...

Abstract

The present invention relates to a female die which is used for die group composing of punch and female die, and to joint automatically the plate overlaying with each other through deformation. The mentioned female die has anvil (7) and female die arc pieces (2,2a) as well as female die sleeve (3) which encircles the mentioned female die arc pieces, the female die arc piece and anvil (7) form hollow chamber together, the female die arc piece inserts into the hollow chamber, and is supported relative to the axes (H) of the hollow chamber with certain angle moving against the spring force athwartships preferring orthogonally. The characteristics is that: the female die has the characteristic as follows: the crust sleeve (3) is rectangle basically with cross section, opens upwards and can be fixed on the base body (1); the female die arc pieces can be supported and guided within the guide hatches (8,8';8a,8a') which is parallel with each other and against to the female die arc piece in the crust sleeve (3); the guide devices (5,5a;9,9a) projecting from the upside of the female die arc piece is used for shape locking and is embedded in the guide hatches.

Description

technical field [0001] The invention relates to a die set for a die set consisting of a punch and a die set for mechanically joining plates laid flat on top of each other by deformation, the die having an anvil and die bows parts and a die sleeve surrounding the die bows which together with the anvil form a cavity into which is inserted and which can be angled with respect to the cavity axis Transversely, preferably orthogonally, it is supported so as to move against the force of the spring. The expansion movement preferably takes place perpendicularly to the hollow chamber axis H, but it can also be directed transversely upwards or downwards. Background technique [0002] Such a negative mold is known, for example, from EP 1 468 758 A1. In order to connect two plates placed one above the other by deformation, the plates are placed one above the other between the punch and the die. The punch is driven down onto the plate and presses the material into the die or into the c...
