Description
Technical field
The present invention relates to a kind of former, be used for the set of molds formed by drift and former, this set of molds is used for mechanically engaging the plate that keeps flat stacked on top of each other by distortion, this former has an anvil and some former camber members and a former sleeve that surrounds these former camber members, these former camber members form a hollow chamber with this anvil, be inserted in this hollow chamber, and these former camber members can be with respect to the hollow chamber axis is angled laterally, preferably against is being supported movably orthogonally.Extensional motion preferably is orthogonal to hollow chamber axis H to carry out, but this extensional motion also can laterally carry out up or down with pointing to.
Background technology
This former is for example known by EP 1 468 758 A1.For two plates stacked on top of each other are connected by distortion, these plates are placed between drift and the former overlappingly.Drift is sailed and is got off to be pressed onto on the plate and be pressed onto material in the former or be pressed onto in the hollow chamber that forms by former camber member and anvil.The former camber member then must move so that hollow chamber increases when distortion, can receive the material that is squeezed thus.
Known former structure is conglobate.Anvil is pressed in the former sleeve.By putting six former camber members that are configured to circle sector shape, each leads these former camber members in by the radial circumference opening of a continuation in the former sleeve at radially outer on anvil.For spring prestressing force being applied on the former camber member in the radial direction, these former camber members are connected by a unique ring spring (O shape ring).Behind joint, the former camber member is pulled back in their home position by means of the power of ring spring.
Slide on the annular support surface of anvil in former camber member complete bottom side with them in offset movement.In order to apply enough reset forces, ring spring therefore corresponding the earth is determined size, and this has determined the excircle of former together.The plate of the intricately distortion that should be connected to each other provides the free space that is used for using circular former sometimes inadequately fully in the junction.In addition, in the time that the extensional motion of former camber member must be limited, can not use known former.
By EP 0 835 701 A2 known a kind of infiltration with rectangle exterior contour engage former (Durchsetzf ü gematrize).The anvil of this former is configured on the matrix.Be provided with two former camber members of arranging with being located opposite one another.Put a former sleeve on this matrix, this former sleeve is sealing on its circumference and aperture that upwards only have a circle basically, and the ledge of former camber member passes this aperture.The former sleeve of sealing is to former camber member guiding and protect these former camber members in order to avoid split away off.The reset force that is used for the spring camber member applies by the spring contact pin of constructing integratedly with the former sleeve, and these spring contact pin are constructed by double seam.In order to make these spring contact pin realize their function, whole former sleeve must be constructed with spring steel, and this spring steel has owing to the spring action restricted spring steel thickness that makes progress.This has shortcoming, and promptly when member impacts to be joined was to the former sleeve, the former sleeve can not receive essential high support force.For fear of former destruction and fragment splash in this case; a fixing former protective device must be located around former; this former protective device increases working width; the operation thickness of former is increased; thus; if when only having restricted member free space available, then this former also seldom is used as circular former.In addition, this former has shortcoming, promptly makes cleaning become difficult and can only clear up by time-consumingly dismantling former sometimes owing to the former sleeve seals basically at circumference.
Summary of the invention
From the problem that is proposed, improve the described former of beginning like this, make that this former can be constructed lessly under the identical situation of stability maintenance, but so that also can use at the member position that intricately obtains.
According to the present invention, a kind of former has been proposed, be used for the set of molds formed by drift and former, this set of molds is used for mechanically engaging the plate that keeps flat stacked on top of each other by distortion, this former has an anvil and some former camber members and a former sleeve that surrounds these former camber members, these former camber members form a hollow chamber with this anvil, be inserted in this hollow chamber, and these former camber members can be laterally angled with respect to hollow chamber axis H, preferably against is being supported movably orthogonally, wherein, this former has following feature: this outer casing sleeve is rectangle basically in cross section, be open upwards and can be fixed on the matrix; These former camber members are supported in can the guide openings that is located parallel the opposite in this outer casing sleeve and lead; The guider that side direction is stretched out on these former camber members is used for shape and is embedded in these guide openings sealedly.
In order to deal with problems, the former of described type is characterised in that:

B) the former camber member is supported in can the guide openings that is located parallel the opposite in outer casing sleeve and leads,
C) be provided with and be used for shape and be embedded in guider guide openings, that side direction is stretched out on the former camber member sealedly.
By the rectangular configuration of outer casing sleeve, former can be constructed very narrowly on an orientation (direction).Because be supported in the guide openings that is located parallel the opposite of female element in the former sleeve and lead,, only occur low frictional force thus and need corresponding low reset force thus so the contact-making surface in the supporting position is little.Simultaneously, guide openings is also protected female element in order to avoid split away off.Therefore outer casing sleeve can be configured to be open upwards, and can easily remove the dirt that adheres to thus.
Configuration only need realize spring function for the spring of each former camber member, thus, can select to preset required spring force by suitable material selection and material thickness.
When only using two former camber members that are located opposite one another, it is narrow that exterior contour can keep.
Spring especially is preferably configured as leaf spring, can make structure space keep very little thus on the longitudinal direction of former.Spring is preferably fixed by the pin that can be pressed in the matrix.Also outer casing sleeve can be fixed on the matrix by means of these pins.
