Abstract

A die rolling ring is provided. The end surface of a rolling ring (1) is provided with at least one knocking block (2). The utility model has the beneficial effect that as the knocking block is arranged, the rolling ring can be dismounted from a die by beating the knocking block, the end surface of the rolling ring is not directly beaten, and the deformation of end surface of the rolling ring is not easy to be caused.

Description

Die rolling ring

Affiliated technical field

The utility model relates to a kind of rolling ring that is used on the mould.

Background technology

At present, be taper fit at contact-making surface such as rolling ring on prestressed pipe, self stressed pipe, the drainpipe mould (centrifuging process) and mould upper flange.Rolling ring when unloading, mould need easily be caused the rolling ring face deformation with knocking rolling ring end face.When mould rotated at a high speed on centrifuge, the mould acceleration equipment wearing and tearing of beating very easily caused equipment breakdown.

Summary of the invention

The utility model provides a kind of Die rolling ring that rolling ring is difficult for causing the rolling ring face deformation when mould unloads.Its technical scheme is: being positioned at the rolling ring end face has at least one to knock piece.Beneficial effect is: knock piece owing to be provided with, knocking is knocked piece and rolling ring can be unloaded from mould, and the rolling ring end face of directly not thumping is difficult for causing the rolling ring face deformation.

Above-mentioned piece and the end face mode of connection of knocking can be welding, screw and multiple mode, wherein preferred weld mode such as is connected.

The above-mentioned piece that knocks can be a plurality ofly, is symmetrical arranged along rolling ring end face circumference.Be convenient to the multiple spot knocking, the dismounting rolling ring.

The above-mentioned block-shaped multiple shapes such as rectangle, circle that can be, the wherein preferred rectangle of knocking.

Description of drawings

Fig. 1 is the front view of the utility model embodiment;

Fig. 2 is the zoomed-in view of A-A section among Fig. 1.

Piece is 2. knocked in 1. rolling rings among the figure, 3. rolling ring end face, 4. slope.

The specific embodiment

As shown in Figure 1, on the periphery of rolling ring 1, be symmetrically welded and be provided with 4 rectangular metals and knock piece 2.As shown in Figure 2, the inner periphery of rolling ring 1 is a slope 4, knocks piece 2 and is positioned at rolling ring 1 a narrower end face.During use, knocking is knocked piece 2 and rolling ring can be unloaded from mould, and rolling ring 1 end face of directly not thumping is difficult for causing rolling ring 1 face deformation.Knocking the piece distortion replaceable piece 2 that knocks when big.

Claims

1. Die rolling ring, it is characterized in that: being positioned at rolling ring (1) end face has at least one to knock piece (2).

2. Die rolling ring as claimed in claim 1 is characterized in that: the described piece (2) that knocks is welding with rolling ring (1) end face mode of connection.

3. Die rolling ring as claimed in claim 1 or 2 is characterized in that: described piece (2) number that knocks is at least two.

4. Die rolling ring as claimed in claim 3 is characterized in that: the described piece (2) that knocks is symmetrical arranged along rolling ring (1) end face circumference.

5. Die rolling ring as claimed in claim 4 is characterized in that: described to knock piece (2) number be 4, is symmetricly set in rolling ring (1) end face circumference.
