Technical field

The present invention relates to pressure vessel manufacturing field, more particularly to a kind of automatic capturing side of large pressurized vessel end socket Method.

Background technology

At present, during the end socket processing and manufacturing of large pressurized vessel, after the arc pressing mold compacting of hydraulic press, by Straight edge in port is uneven or the problems such as shirt rim be present, it is necessary to which by end socket centering cutting action, existing cut edge is By artificial method for centering, because the quality of end socket is big（3 meters or so of diameter）Working strength is big, and centering effect is poor, straight flange after cut edge The height error of edge can only be typically controlled in 10mm or so, and then influences the welding and sealing of packing pressure container.

The content of the invention

Present invention aims at a kind of method that centering processing can be quickly carried out to large pressurized vessel end socket is provided, with solution Certainly above mentioned problem.

To achieve the above object, the invention discloses a kind of pressure vessel head automatic capturing method, comprise the following steps：

1）End socket lifting is placed on end socket placement rack；

2）Start end socket placement rack and drive end socket rotation, drive the roller on alignment device synchronous into the end socket placement rack The heart moves；

3）Treat the end socket and the infrared control switch contact on the alignment device, infrared control switch all light When, the motor stops, and completes centering；

4）Start the magnechuck on end socket placement rack, the fixed end socket；

5）Adjust trimming device and trimming is carried out to the end socket.

Further, the alignment device and trimming device are arranged on the outer of end socket placement rack, can be to end socket placement rack The roller and infrared control switch of central synchronous movement are arranged on the alignment device, and the center of the roller can form one The individual circle concentric with the end socket placement rack.

Further, its edge three are provided with the end socket placement rack to be used to support the universal of the end socket Ball.

Further, its edge is provided with three electricity for being used to adsorb the fixed end socket on the end socket placement rack Magnetic-disc.

Further, the roller of the alignment device is driven by same motor to be transported to the center of the end socket placement rack It is dynamic.

Further, the quantity of the roller on any alignment device be two, and all rollers be centrally located at The center of the end socket placement rack is concentric.

Compared with prior art, the advantage of the invention is that：

This method can realize the automatic capturing trimming of large pressurized vessel, wherein, the automatic capturing cutting that automatic capturing uses The end socket of device is supported on circular head placement rack with three multi-directional balls, drives roller to be easily achieved envelope by alignment device The adjustment of head, centering work, this kind of centering work can be automatically performed when each infrared control switch contact is to end socket surface Full-automation is realized, greatly improves the efficiency of centering cutting.

Below with reference to accompanying drawings, the present invention is further detailed explanation.

Embodiment

Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims Implement with the multitude of different ways of covering.

As shown in figure 1, the invention discloses a kind of pressure vessel head automatic capturing method, comprise the following steps：

1）The lifting of end socket 6 is placed on end socket placement rack 1；

2）Starting end socket placement rack 1 drives end socket 6 to rotate, and drives the roller 4 on alignment device 2 synchronous to end socket placement rack 1 Move at center；

3）When end socket 6 contacts with the infrared control switch 5 on alignment device 2, infrared control switchs 5 all light, motor stops Only, centering is completed；

4）Start the magnechuck 8 on end socket placement rack 1, fixed seal head 6；

5）Adjust trimming device 3 and trimming is carried out to end socket 6.

The operation principle of this method is that the alignment device 2 that three of the periphery of end socket 6 are provided with roller 4 drives roller 4 synchronous Moved at the uniform velocity to center of circle direction, so as to realize the automatic centering of end socket 6, wherein, roller 4 is all the time on a circular arc line, three Roller 4 is provided with infrared control switch 5, when three rollers 4 touch 6 surface of end socket, infrared control switch 5 Lamp all light, now automatic roller 4 of closing is moved simultaneously, and the automatic capturing of end socket 6 is completed, and then starts cut edge.By this kind of mode The 700 more than one piece end sockets 6 completed, its ellipticity error are controlled in ± 1.5mm, and die mould model clearance control is in 2mm.

In the present embodiment, alignment device 2 and trimming device 3 are arranged on the outer of end socket placement rack 1, can be placed to end socket The roller 4 and infrared control switch 5 of seat 1 central synchronous movement are arranged on alignment device 2, and the center of roller 4 can form one The individual circle concentric with end socket placement rack 1.

In the present embodiment, its edge is provided with three multi-directional balls 7 for being used to support end socket 6 on end socket placement rack 1, So as to reduce friction, the centering of end socket 6 can be promoted with less power, while the device such as motor driven can be selected more Small-power model, has saved cost.

In the present embodiment, its edge is provided with three electromagnetism for being used to adsorb fixed seal head 6 on end socket placement rack 1 Sucker 8, after centering is completed, you can automatic absorbing is completed quickly to fix, and trimming device 3 can start trimming work.
