Abstract
The invention relates to a reinforcement ring manufacturing method, in particular to an angle steel bending method. A method for bending rows of angle steels comprises a plate bending machine. The method comprises the following steps: 1, taking a steel plate and arranging one group of angle steels to be bent on the steel plate in parallel, wherein every two angle steels form a group and are connected with the steel plate in a multi-spot electric welding manner; 2, winding the angle steel rows manufactured in the step 1, wherein the method for winding the bending radius is the same as the method for winding the steel plate; 3, taking down a workpiece after finishing winding, grinding and disassembling the angle steel so as to bend the angle steels. According to the method, the plate winding machine is not modified, so that the influence on the plate winding machine is greatly reduced.
Description
Technical field
The present invention relates to fixing collar to make, particularly relate to a kind of angle steel bending method.
Background technology
In large-scale circular structure or pipeline manufacture; outer wall can be designed to the fixing collar that enhancing structural rigidity prevents circular configuration to be out of shape usually; therefore the angle steel reinforced lap welding bending different-diameter is needed to be connected on outer wall according to different processing dimensions; owing to being make at the construction field (site); usually all adopt artificial stupid power heating to bend, work efficiency is low, and cost is high; labour intensity is large, and Forming Quality is not good.
CN202447454 U discloses a kind of angle bending machine, and namely it by being provided with mould to the transformation of veneer reeling machine on top roll or lower roll, and the annular groove that wing plate mould periphery having confession angle steel stretches into is to realize the bending of angle steel.But this method needs to transform veneer reeling machine, impact is existed on the roller of veneer reeling machine, further can affect the roll bending function of veneer reeling machine itself.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of bending method in a row of angle steel.The present invention does not need to transform veneer reeling machine, greatly reduces the impact on veneer reeling machine.
In order to solve the problems of the technologies described above, a kind of bending method in a row of angle steel, it comprises a squeezer, and comprises the following steps:
Step one, gets a steel plate, is arranged in parallel within steel plate by one group of angle steel to be bent, and every two angle steel are one group and are connected with the electric welding of steel plate multiple spot;
Step 2, angle steel row step one made carries out rolling processing with veneer reeling machine, and bending radius method for coiling is equal to steel plate and rolls,
Step 3, takes off workpiece after having rolled, and polishes and decomposes angle steel, thus completes the bending of angle steel.
Construction technology of the present invention is simple to operate, the equipment that machining needs also is in daily use, directly rolling of angle ring can be carried out on veneer reeling machine, and just can the carrying out of low input in enormous quantities not make by construction condition restriction, angle ring can also be improved significantly and bend efficiency, bend radian and mate completely with weldment, avoid the secondary of component when making to correct, thus reduce labour's input, and can accomplish that material is substantially lossless, stop waste raw material.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, first will the angle steel that rolls be needed to be arranged in parallel within steel plate 2 by one group of angle steel to be bent, every two angle steel 1 be one group and be connected with the electric welding of steel plate multiple spot; Thus ensure that roller bed uniform force and angle steel can not produce abnormal displacement.For making stressed symmetry in coiling process, prevent workpiece distortion lateral bending, when rolling angle ring by group to after bend work again, every two angle steel are one group, and angle steel is spot-welded together, then this entirety three rolls plate bending machine 3 is carried out rolling processing, bending radius method for coiling is equal to steel plate and rolls, take off workpiece after having rolled, polish and decompose angle steel, thus obtain the angle steel reinforced circle that rolled, welding with the steel plate together rolled according to making drawing, circle needed for making or cone-shaped component, processing one-shot forming, radian fits like a glove.(veneer reeling machine power decision rolls quantity)
The end of the angle steel rolled out in this way, substantially without remained straight edge, directly can be used for the welding of reinforcement, compensate for and needs to give this deficiency of bent-up end portion with miscellaneous equipment, reach the object of saving material.Therefore, can make at cylinder class formation and widely use in large-scale pipeline construction.
