Abstract
The invention provides a method for correcting a single calandria. The method comprises the following step of placing the calandria of which one end is fixed on a platform according to a model, and ischaracterized in that a lower channel steel is inserted into the bottom of the calandria, and the lower channel steel and an upper channel steel are fixed through bolts, so that the upper channel ste el is arranged on the top of the calandria; and then, a positioning block is inserted into one side of the calandria to be corrected; an L-shaped fixing block is built on one side of the upper channelsteel and the lower channel steel; and finally, force is applied to the side surface of the L-shaped fixing block by a jack to realize correction of the single calandria, and the steps are repeated u ntil all the calandrias to be corrected are corrected. The method has the advantages that the problem of no space in calandria for cooling correction can be solved, and various quality problems causedby heat correction are radically avoided; and related frock clamps used in the method have simple and practical structure, and can be widely applied to similar products.
Description
Technical field
The present invention relates to a kind of method of correcting single calandria, be used for boiler tubes of power plant row's correction, belong to the bearing calibration technical field of making in the assembling.
Background technology
Domestic station boiler has obtained huge development at present, and product demand is vigorous unusually.In station boiler, the application of high-alloy steel is very general, and steel alloy is when deforming, the cold sizing difficulty is very big, very high during thermal recalibration to temperature requirement, to such an extent as to many times should not adopt thermal recalibration, especially in calandria structure, both do not had the space of putting to good use of cold sizing, be not suitable for thermal recalibration yet.
Summary of the invention
The purpose of this invention is to provide a kind of some existing simple frock clamps that utilize, solve the method for the correction problem of individual tubes in the comb.
In order to achieve the above object, technical scheme of the present invention has provided a kind of method of correcting single calandria, comprising:
Step 1, on platform, emit the sample of comb;
Step 2, the comb that an end is fixing are placed on the platform by sample, it is characterized in that:
Step 3, the bottom that the bottom channel-section steel is inserted comb, and adjust to the right place according to the sample of the described comb of step 1;
Step 4, top channel-section steel and bottom channel-section steel are fixed, made the top channel-section steel be arranged on the top of comb with screw;
Pipe in step 5, the observation comb finds the pipe that needs correction, and determines the direction of correction;
One side of step 6, pipe that locating piece insert to need is proofreaied and correct, and put up L type fixed block at top channel-section steel and bottom channel-section steel one side-sway;
Step 7, utilize the side application of force of jack pair L type fixed block, realize the correction of single pipe;
Step 8, repeating step 5 be to step 7, all pipes that need proofread and correct in having proofreaied and correct comb.
In similar comb product, the spacing between the comb is very little, and very short, can't raise, and also has no idea to insert all the other aligning tools, so substantially implement the space of correction.
Adopt method provided by the invention, can solve among the similar pipe row and not implement the difficult problem in the space of cold sizing, and also avoid the various quality problems that thermal recalibration brings fully, the relevant tool clamp structure that uses among the present invention simultaneously is simple, practicality can be extensive use of in similar products like.
Description of drawings
Fig. 1 is the main schematic diagram of the method for enforcement a kind of correcting single calandria provided by the invention;
Fig. 2 is the vertical view of the method for enforcement a kind of correcting single calandria provided by the invention.
The specific embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
As shown in Figures 1 and 2, the step of the method for a kind of correcting single calandria provided by the invention is:
Step 1, on platform, emit the sample of comb;
Step 2, the comb 4 that an end is fixing are placed on the platform by sample;
Step 3, the bottom that bottom channel-section steel 3 is inserted combs 4, and adjust to the right place according to the sample of the described comb of step 1;
Step 4, top channel-section steel 1 is fixing with bottom channel-section steel 3 with screw 2 makes top channel-section steel 1 be arranged on the top of comb 4;
Pipe in step 5, the observation comb 4 finds the pipe that needs correction, and determines the direction of correction;
Step 6, locating piece 5 is inserted a side that needs the pipe proofreaied and correct, and put up L type fixed block 6 at top channel-section steel 1 and bottom channel-section steel 3 one side-swaies;
Step 7, utilize the side application of force of 7 pairs of L types of jack fixed block 6, exerting all one's strength affacts on the pipe that needs to proofread and correct, and realizes the correction of single pipe;
Step 8, repeating step 5 be to step 7, all pipes that need proofread and correct in having proofreaied and correct comb 4.
