Abstract
The utility model belongs to a mould, concretely relating to a device for superposing parts together. According to the design scheme offered by the utility model, a cavity which can contain slice shape parts is arranged in a striction ring, the inner wall of the cavity is provided with fit strips, and the inner end face of the fit strip protrudes the inner wall of the cavity. The shape of the cross section of the cavity is identical to or approximate to the shape of the slice shape part, and the cross section of the cavity is slightly bigger than the cross section of the slice shape part. Four fit strips are provided, symmetrically distributed on the two sides of the cavity. The space of the inner end faces of each pair of fit strips is equal to the width of the slice shape part. The utility model can conveniently adjust the magnitude of interference between the striction ring and the slice part, and extend the service life of the striction ring.
Description
Technical field
The utility model belongs to a kind of parts in the mould, specifically a kind of device that part is superimposed of being used for.
Background technology
To be the frictional force that produced during by tightening ring of the part of sheet be added to down the folded riveting point of last a slice in the folded riveting point of a slice in the effect of tightening ring.The quality quality of tightening ring directly has influence on the surface quality of bond strength, surface smoothness and side between flat parts, and these depend on the magnitude of interference of tightening ring to a great extent.In the prior art,, in use can't adjust the magnitude of interference between tightening ring and flat parts because used tightening ring is all-in-one-piece, in case and after tightening ring is worn, just can only scrap, relatively waste.
Summary of the invention
The purpose of this utility model is to design a kind of tightening ring that has panel, with the convenient magnitude of interference of adjusting between tightening ring and flat parts, and the useful life of prolongation tightening ring.
According to design provided by the utility model, the cavity that can hold flat parts is set in tightening ring, at the inwall of cavity panel is set, the inner face of this panel stretches out the inwall of cavity.
The transverse shape of cavity is identical with the shape of flat parts or close, and is slightly larger than flat parts.Panel has 4, is symmetrically distributed in the both sides of cavity, and each equals the width of flat parts to the inner face spacing of panel.
The utility model has the advantages that: owing to be provided with panel at the inwall of tightening ring, during use, the edge of flat parts only contacts with the inner face of panel, therefore, when the magnitude of interference between needs adjustment tightening ring and flat parts, only need to adjust the magnitude of interference between panel inner face and flat parts, more convenient; In addition, when the magnitude of interference of finding panel because of wearing and tearing when not enough, can change panel, needn't as originally, change whole tightening ring, saved material, made things convenient for operation.

Embodiment
The cavity that can hold flat parts 2 is set in tightening ring 3, inwall at cavity is provided with panel 1, the inner face of this panel 1 stretches out the inwall of cavity, and the inwall of cavity is not contacted with flat parts 2, and the magnitude of interference that tightening ring 3 and flat parts are 2 is by the inner face control of panel 1.The transverse shape of cavity is identical or close with the shape of flat parts 2, and is slightly larger than flat parts 2, so that panel 1 is installed and is placed flat parts 2.Panel 1 has 4, is symmetrically distributed in the both sides of cavity, and each equals the width of flat parts 2 to the inner face spacing of panel 1.The quantity of panel 1 is decided by the size of flat parts 2, when flat parts 2 is big, can utilize polylith panel 1, generally speaking, the quantity of panel 1 should be less than 4, during use, flat parts 2 slices are overlayed in the cavity of tightening ring 3, and the frictional force that is produced when utilizing flat parts 2 by panel 1 is added to down the folded riveting point 4 on last a slice flat parts 2 in the folded riveting point 4 of a slice flat parts 2.When the magnitude of interference of 2 of space that 4 blocks of panels 1 of needs adjustment are surrounded and flat parts, can realize by changing different panel 1.
Claims (3)
1, have the tightening ring of panel, it is characterized in that: in tightening ring (3) cavity that can hold flat parts (2) is set, at the inwall of cavity panel (1) is set, the inner face of this panel (1) stretches out the inwall of cavity.
2, tightening ring according to claim 1 is characterized in that: the transverse shape of cavity is identical or close with the shape of flat parts (2), and is slightly larger than flat parts (2).
3, tightening ring according to claim 1 is characterized in that: panel (1) has 4, is symmetrically distributed in the both sides of cavity, and each inner face spacing to panel (1) equals the width of flat parts (2).
