Description

Diamond flange elbow processing tool

Technical Field

The utility model relates to the field of flange machining, in particular to a flange machining tool.

Background

The diamond flange bent pipe is a special-shaped part and is commonly used for sealing and communicating underwater pipelines. The perpendicularity and concentricity of the upper flange surface and the lower flange surface are required to be high. Because the shape of the workpiece is special, the clamping tool which can be matched with the workpiece is lacking in the market, and the machining and clamping are very difficult.

Disclosure of Invention

The utility model aims to solve the problems of special shape, difficult processing and clamping of a diamond flange bent pipe, and provides a diamond flange bent pipe processing tool for improving the working efficiency.

The utility model adopts the technical proposal for solving the problems that:

the utility model provides a diamond-shaped flange pipe bending frock, includes bottom plate 1, sets up rack 2 on the bottom plate 1, and rack 2 upper portion is platen 3, and platen 3 bottom sets up fixed block 4, and threaded connection has lead screw 5 on the fixed block 4, and two sets of spacing piece 6 of parallel arrangement have first stop bolt 7 on the stopper 6 on the platen 3.

Preferably, the center of the platen 3 is provided with a center through hole 8.

Preferably, the central through hole 8 is square.

Preferably, a second limit bolt 9 is fixed on the platen 3, and the second limit bolt 8 is disposed at a side far from the limit block 6.

Preferably, the end of the screw rod 5 is provided with a tightening block.

Preferably, four positioning holes 10 are formed on two sides of the bottom plate 1. The locating holes 10 may be fitted with table locating bolts.

The diamond flange pipe bending tooling disclosed by the utility model is used for clamping a diamond flange pipe and milling the end face of the flange, so that the perpendicularity deviation can be ensured to be about 0.1, and the surface roughness reaches Ra3.2. The device has simple structure and convenient use; the clamp is fixed in a multi-point positioning way, and the clamping is stable and reliable.

FIG. 1 is a front view of a diamond flange pipe bending tooling of the present utility model;

FIG. 2 is a top view of the diamond flange pipe bending tooling of the present utility model;

fig. 3 is a rear view of a diamond-shaped flange elbow.

The reference numerals are as follows: the device comprises a 1-bottom plate, a 2-bench, a 3-bedplate, a 4-fixed block, a 5-screw rod, a 6-limiting block, a 7-first limiting bolt, an 8-central through hole, an 8-second limiting bolt and a 10-positioning hole.

Description of the embodiments

The utility model is further described below with reference to examples and figures.

Examples

As shown in fig. 1 and 2, the embodiment discloses a diamond flange pipe bending tooling, the tooling device comprises a bottom plate 1, a plurality of U-shaped positioning holes are formed in the front side and the rear side of the bottom plate 1, in the embodiment, two holes are formed on one side, and the tooling can be installed by matching with a vertical milling machine. The base plate 1 is fixedly provided with a rack 2, a bedplate 3 is fixed on the upper part of the rack 2, a square central through hole 8 is formed in the center of the bedplate 3, a fixed block 4 is arranged at the bottom of the bedplate 3, the fixed block 4 is in threaded connection with a screw rod 5, and the tail end of the screw rod 5 is connected with a tight supporting block.

Two groups of limiting blocks 6 are arranged on the bedplate 3 in parallel, and the limiting blocks 6 are provided with first limiting bolts 7 which are in threaded connection with the limiting blocks 6. A second limit bolt 9 is arranged in the direction away from the limit block 6 behind the central through hole 8. The second limit bolt 9 is in threaded connection with the bedplate 3, and the tail end of the second limit bolt is fastened by a nut.

When the flange bending machine is used, a diamond-shaped flange bending pipe (the structure is shown in fig. 3) is placed on the bedplate 3, the end face of the flange to be processed is arranged at the outer side of the limiting blocks 6, the first limiting bolts 7 on the limiting blocks 6 at two sides are adjusted to enable the bolts to be parallel and prop against the inner side faces of the flange, the lower part of the flange bending pipe stretches into the central through hole 8, and the second limiting bolts 9 are clamped at the rear part of the bending pipe, so that the bending pipe part on the bedplate is basically fixed; and then the screw rod 5 is rotated to enable the abutting block to abut against the lower part of the bent pipe, so that the flange positioning and fixing are completed.

The above description is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto. Any person skilled in the art, within the scope of the present disclosure, may apply to the present utility model, and equivalents and modifications may be substituted or altered by elements thereof.
