Drilling and insertion guiding mechanism for firecracker assembling

Abstract

The invention discloses a drilling and insertion guiding mechanism for firecracker assembling. The drilling and insertion guiding mechanism comprises two forming guiding grooves capable of reciprocating up and down. Groove openings of the two forming guiding grooves are opposite. Groove cavities of the two forming guiding grooves are each internally provided with a drilling pin. The drilling pins reciprocate up and down along the groove cavities. A push guiding piece capable of reciprocating up and down is arranged between the two forming guiding grooves. A forming core capable of stretching out and drawing back is arranged between the two forming guiding grooves. The stretching-out forming core blocks the downward movement of the push guiding piece. The mechanism is high in work stability and reliability; firecrackers are not prone to damage; the insertion guiding quality is good; in the insertion guiding process, leads can not be damaged; a drilling mechanism and an insertion guiding mechanism can be integrated at a station so that functional movements of the drilling mechanism and the insertion guiding mechanism can be completed, and the machining quality of pre-drilling and insertion guiding is effectively improved; the troublesome of movable positioning is avoided, machining time is greatly shortened, production efficiency is improved, and possibility of failures is lowered.

Description

technical field [0001] The invention relates to pot assembly processing equipment for combined fireworks, in particular to a device for making lead holes and inserting lead wires in the lead holes. Background technique [0002] In the process of making combined fireworks, there is a process commonly known as "pot grouping". First, multiple fireworks tubes are combined into a row (called a tube row), and then two adjacent fireworks tubes are drilled to insert the overheating fuse ( This process is called continuous lead); then the multiple rows of fireworks tubes that have been connected are glued together to form a block, and holes are drilled on the adjacent two rows of fireworks tubes to insert the overfire fuse (this process is called encirclement) . In the above-mentioned connecting and enclosing processes, it is necessary to complete the punching and inserting work, and the working mechanism is also roughly the same, the difference is that the spatial position of the p...

Problems solved by technology

[0005] However, the existing punching and inserting mechanism has low working reliability due to the following disadvantages, lack of guarantee for product quality and safety, and is difficult to achieve theoretical production efficiency:

[0006] 1. The perforating needle is equipped with a guide groove, and the cross-section of the needle body is a U-shaped structure. A U-shaped tongue-shaped incision will be cut on the paper fireworks tube. The U-shaped tongue-shaped incision will be pressed down under normal circumstances. Lead holes are formed, but under the following conditions: 1) The U-shaped tongue is not pressed enough; 2) The tongue rebounds after being pressed down

The U-shaped tongue blocks the lead hole, which will hinder the entry of the lead wire and reduce the success rate of insertion

[0007] 2. The needle body formed by the thin-walled U-shaped groove is easy to damage the ring and needs to be replaced frequently

[0008] 3. When the lead wires are arranged into an inverted U shape, the lead wires are incorporated into the guide grooves. During the inclusion process, the needles are easy to damage the lead wires and destroy the structural strength of the lead wires.

[0009] 4. When the tine is reset and withdrawn, it is easy to bring out the inserted lead wire; at the same time, the inner wall of the guide groove rubs against the lead wire at high speed and in a large area during withdrawal, which may easily cause the lead wire to be ignited
