Abstract
The utility model provides a special fixture for bending system angle ring, includes first splint, second splint, and first splint, second splint are the components of a whole that can function independently integrated configuration, and first splint, second splint built -up connection constitute ring shape, at annular inner circle equipartition bolt hole, are equipped with fixing bolt in the bolt hole. Adopt the utility model discloses curved system angle ring has saved the process of cutting off again after two angle steel spot welding back -to -back, the curved system, has improved work efficiency greatly, has lightened artifical intensity of labour, avoids in electric welding, the cutting -off process leading to the fact the damage to the angle steel surface, is favorable to improving the angle ring formability in addition.
Description
Technical field
This utility model relates to a kind of frock for deformation processing, especially for the special fixture bending angle ring.
Background technology
Angle ring to be used in some engineering equipments, the angle ring as supported as tower landing slab in Large Towers kind equipment platform structure is requisite.Angle ring is divided into external vertical rib angle ring as shown in Figure 3 and interior stud angle ring as shown in Figure 4 according to engineering structure needs.Angle ring currently for major diameter rolls relatively easily on veneer reeling machine, and the angle ring for minor diameter generally uses plate welding processing, hot bending or rolls.Method for coiling is the most easy to implement relative to welding processing and hot bending process process, but first will be by the most spot-welded together for two angle steel before rolling, to ensure angle steel stress equalization, prevent from partially falling, also two angle steel solder joints are cut off after having rolled, this quadrat method adds the time-consuming and labor workload rolled, and the shaping of angle ring is the most bad.
Utility model content
The purpose of this utility model is the drawback for prior art, it is provided that a kind of special fixture for bending angle ring that can improve angle ring formability and roll work efficiency.
Problem described in the utility model realizes with following technical proposals:
A kind of special fixture for bending angle ring, including the first clamping plate, the second clamping plate, the first clamping plate, the second clamping plate are Split assembled structure, and the first clamping plate, the second clamping plate combination connect and compose annular, at the uniform bolt hole of inner ring of annular, in bolt hole, it is provided with fixing bolt.
The above-mentioned special fixture for bending angle ring, described first clamping plate, the second clamping plate are semi-circular, are respectively equipped with trapezoidal projection at two straight flanges of the first clamping plate, be respectively equipped with and mate the trapezoidal groove that tenon closes with trapezoidal projection at two straight flanges of the second clamping plate.
The above-mentioned special fixture for bending angle ring, described fixing bolt arranges four, and the first clamping plate, the second clamping plate are respectively equipped with two fixing bolts.
The above-mentioned special fixture for bending angle ring, the first clamping plate, the second clamping plate one end face of the annular involuted is provided with chamfering.
This utility model bends problem for solving angle ring and designs, and described special fixture uses in pairs, and it constitutes and includes at the first clamping plate that mutual tenon closes and the second clamping plate, the first clamping plate and the second clamping plate upper roller through being bolted to veneer reeling machine or lower roll.When rolling angle ring, a face of angle steel to be processed is seated between two special fixtures, two special fixtures constitutes the location to angle steel to be processed.Use this utility model bend angle ring eliminate by two back-to-back spot welding of angle steel, bend after the operation cut off again, substantially increase work efficiency, alleviate hand labor intensity, it is to avoid angle steel surface is caused damage by electric welding, cutting-off process, and is conducive to improving angle ring formability.

Detailed description of the invention
Referring to Fig. 1, Fig. 2, this utility model includes the first clamping plate the 1, second clamping plate 2 and fixing bolt 3.First clamping plate, the second clamping plate are Split assembled structure, and the first clamping plate, the second clamping plate are semi-circular, constitute annular after the first clamping plate, the second involutory connection of clamping plate, and at the uniform bolt hole of inner ring of annular, fixing bolt 3 screws in bolt hole.As seen from the figure, being respectively equipped with trapezoidal protruding 1-1 at two straight flanges of the first clamping plate, be respectively equipped with trapezoidal groove 2-1 at two straight flanges of the second clamping plate, after the first clamping plate, the second clamping plate combination, trapezoidal projection and trapezoidal groove coupling tenon close.Diagram embodiment fixes bolt and is provided with four.One end face of the annular that the first clamping plate, the second clamping plate involute is provided with chamfering.Need to use in pairs when this utility model is used for bending angle ring.
Use state of the present utility model is described below as a example by three rolls plate bending machine:
Referring to Fig. 5, Fig. 6, it is two right to use when this utility model is used for processing external vertical rib angle ring, two pairs of special fixtures are respectively fixed at two lower rolls 6 of veneer reeling machine, the end face that each special fixture is provided with chamfering is corresponding with angle steel, gap is left between two special fixtures of every pair, this gap is slightly larger than the wall thickness of angle steel 4, so that the angle steel in coiling process can pass through smoothly from gap, then bolt 3 is fixed in turn, fixing bolt is made to withstand on lower roll outer wall, by adjusting the extension elongation of fixing bolt, ensure that the cylindrical of special fixture is concentric with the lower roll cylindrical of veneer reeling machine, the clamping action of special fixture is prevented effectively from angle steel coiling process and partially falls.Then can start veneer reeling machine to carry out external vertical rib angle ring and roll.
Referring to Fig. 7, Fig. 8, need to use a pair when this utility model is used for processing interior stud angle ring, a pair special fixture is fixed at the upper roller 5 of veneer reeling machine, the end face that each special fixture is provided with chamfering is corresponding with angle steel 4, gap is left between two special fixtures, this gap is slightly larger than the wall thickness of angle steel 4, so that the angle steel in coiling process can pass through smoothly from gap, then bolt 3 is fixed in turn, fixing bolt is made to withstand on lower roll outer wall, by adjusting the extension elongation of fixing bolt, ensure that the cylindrical of special fixture is concentric with the lower roll cylindrical of veneer reeling machine, then can start veneer reeling machine and carry out rolling of interior stud angle ring.
