Description

Auxiliary device for welding alloy blade of under-pressure tapping machine

Technical Field

The utility model relates to a tooling equipment, especially a tapping machine alloy blade welding auxiliary device are pressed in area.

Background

The method is characterized in that pipeline branches are added to a main pipe network of a gas pipeline due to the requirements of production process, environmental protection, extension and the like of steel enterprises, the main pipe network needs to be subjected to pressurized tapping operation due to the pressure gas of a conveying belt in the main pipe network so as not to influence normal production, and used equipment is a pressurized tapping machine. The operation principle is as follows: firstly, prefabricating the pipe joint under the line, wherein the diameter of the pipe joint is the same as that of the branch pipe which is increased in advance, and one end of the pipe joint is welded with a flange. The other end of the pipe joint is welded with the main pipe network pipeline, so that the quality of a welding seam is ensured. The flange end is connected with the gate valve with the same diameter and then connected with the flange at the cutter head of the tapping machine, and the flange is sealed. And (4) opening the gate valve, deepening a rotary cutter head of the tapping machine, tapping, cutting a hole in the wall of the main pipe network pipeline, and discharging the generated hole plate excess material along with the rotary cutter rod. In the actual work process, because main pipe network pipeline material generally is Q235, lead to improving the alloy cutter head when the operation of trompil before the improvement and break the tooth and damage the phenomenon frequently, trompil success rate 80%. And each failure of tapping can cause valve waste and require reinstallation of the weld. In addition, the risk of gas leakage also exists, and spare parts, labor and materials are wasted. According to statistics, 50 holes are drilled every year, 40 cutter heads of each drilling machine and 2000 alloy cutter heads in total, 400 damages are caused, and the damage rate (the hole drilling failure probability) accounts for 20%; the valve and the tapping machine need to be welded again for 1 time each time. Resulting in low work efficiency and increased cost.

Through field analysis, the reasons for the damage of the alloy cutter head are as follows: (1) personnel do not operate the tapping machine according to the standard; (2) the hardness of the required hole is higher, and the abrasion of the tool bit is higher; (3) The cutter heads of the tapping machine are not on the same circumference, so that the cutter heads are damaged unevenly under stress. The reason for the greatest damage is that the cutter head is stressed unevenly, and the cutter head is not arranged on the same circumference during installation, welding and repair. The probability of damage is big when some tool bits go out or cave in and lead to the trompil, and the tool bit that the atress is big can damage fast, has played the atress degree of other tool bits more, finally leads to the rectifying and reforming tool bit to damage, and the trompil operation fails.

Therefore, an auxiliary device for welding the alloy blade of the pressure tapping machine, which can ensure that the cutter head of the tapping machine is arranged on the same circumferential plane, is urgently needed.

SUMMERY OF THE UTILITY MODEL

The technical task of the utility model is not enough to above prior art, provides a tapping machine alloy blade welding auxiliary device is pressed in area, through using this frock, when making welding tapping machine alloy blade, can guarantee that each blade is in same circumference to can be within 0.5mm with the error.

The utility model provides a technical scheme of its technical problem is: the utility model provides a punching machine alloy blade welding auxiliary device is pressed in area which characterized in that: comprises a central drill, a bearing and an adjustable screw; the central drill is used as a shaft and sleeved with a bearing; bearing housing fixed connection two screw rod seats, two screw rod seats on same straight line, have two adjustable screw rods and screw rod seat threaded connection, the outer end of adjustable screw rod be connected with supplementary baffle.

The bearing is a deep groove ball bearing;

two semicircular needle bearings are arranged between the central drill and the bearing inner sleeve.

Compared with the prior art, the utility model discloses following outstanding beneficial effect has:

1. by using the utility model, when the alloy blades of the tapping machine are welded, the blades can be ensured to be positioned in the same circumference, the error can be within 0.5mm, the problem that the blades with large stress are dropped first due to the uneven stress of the blades when the tapping machine is used for tapping is avoided, the result of the failure of the whole tapping operation is aggravated, the success rate of tapping is improved, and the tapping failure rate is reduced from 20% to 0%;

2. the production efficiency of equipment is improved, the cost of spare parts is reduced, and the cost of repairing the tapping machine is reduced;

3. the occurrence of unsafe behaviors in the operation process is reduced, and the work safety is improved.
