Method for machining honeycomb-shaped lead guider

Abstract

A honeycomb-shaped lead guider is characterized by comprising pipes, bonding layers and an outer frame. A method for machining the honeycomb-shaped lead guider includes a first step of machining the pipes, a second step of machining the outer frame, a third step of arranging the pipes, a fourth step of taking out the pipes, a fifth step of coating the bonding layers on the pipes, a sixth step of blowing off cyclohexanone in the inner holes of the pipes, a seventh step of removing a prismatic fixing frame and an eighth step of forming the honeycomb-shaped lead guider. All the pipes of the lead guider with the structure and the outer frame of the lead guider with the structure are made by dies through injection moulding, production and manufacturing are convenient to conduct, the formed pipes are the same in size, the hole walls are smooth so that threading can be facilitated, the pipes are connected with one another through the bonding layers, the pipes are arranged in a compact and neat mode, labor is saved in the machining process, the machining is easy to conduct, the operation is convenient to conduct, and the percent of pass is high.

Description

technical field [0001] The invention relates to a processing method of a honeycomb lead wire guide and a tool for processing firecrackers (small firecrackers). Background technique [0002] The gunpowder wire for processing fireworks (small firecrackers) first passes through the lead wire guide, and then inserts the gunpowder wire into the gun barrel through the guider, and then fills the gunpowder to make a complete fireworks. The existing wire guide used for threading gunpowder wires uses a flat plate, and drills the lead holes in the flat plate. The disadvantages are: first, the processing speed is very slow, and the flat plate must be marked during processing, and then the flat plate is clamped on the drilling machine to work. On the table, drilling one hole by one hole is troublesome and time-consuming due to many holes; second, the wall is easy to break when drilling, and the scrap rate is high, because the arrangement of the holes is very dense, and the wall between t...

AI Technical Summary

Problems solved by technology

The existing wire guide used for threading gunpowder wires uses a flat plate, and drills the lead holes in the flat plate. The disadvantages are: first, the processing speed is very slow, and the flat plate must be marked during processing, and then the flat plate is clamped on the drilling machine to work. On the table, drilling one hole by one hole is troublesome and time-consuming due to many holes; second, the wall is easy to break when drilling, and the scrap rate is high, because the arrangement of the holes is very dense, and the wall between the holes is thin, so it is easy to The hole wall is damaged and cannot be repaired. Sometimes it takes a long time to drill, and the whole board is scrapped due to the damage of the hole wall, which is a serious waste. There are many burrs on the hole wall, which is not easy to repair, and the threading is not smooth. In addition, due to the heating of the plate caused by drilling, the hole wall is deformed, and threading is difficult. Fourth, the hole distance error is large. Although the workpiece is positioned and clamped during drilling, it cannot After all, it is not formed at the same time. After drilling densely packed holes, the spacing error is relatively large; fifth, the strength is poor and it is easy to break.
