A sewing processing method and product suitable for connecting collars of aerial bomb umbrellas

Abstract

The invention discloses a sewing processing method suitable for a connecting lantern ring of an aerial bomb parachute. The method comprises the following steps that (1) a main rope is scribed, rope ends are reserved at the two ends of a main rope, lines are scribed in the middle of the main rope at equal intervals, and a shearing gap is reserved between every two intervals; (2) the scribed main rope is bent into an annular structure along positioning nails on a workbench, and the two ends of the main rope are overlapped to form an overlapping part; (3) the overlapping part of the annular structure obtained in the step (2) is sewed through a thread, the sewing operation adopts a sawtooth line spacing mode, and the needle distance is 25<-0><+5> tooth / 100 mm; (4) the step (2) and the step (3) are repeated until the whole annular structure is sewed; and (5) the whole annular structure is sealed off along the shearing gaps. The invention further discloses the connecting lantern ring processed through the method. Through the method, 35% of raw materials can be saved in the volume production process, and material waste is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of parachutes, and in particular relates to a sewing processing method and product suitable for connecting collars. Background technique [0002] The parachute is a kind of parachute, which is mainly used for the stable deceleration of bombs and other offensive weapons and service weapons, packaging accurate ballistics, increasing the blanking time and retracting distance, increasing the angle of entry into the soil or water, and ensuring the safety of the carrier , to achieve the intended combat effectiveness. [0003] A certain type of connecting collar is a kind of rope part in a certain type of aerial bomb umbrella, which is connected with one end of the aerial bomb umbrella, and the aerial bomb umbrella is stored in the umbrella cabin. When working, pull the rope to pull the air bomb parachute out from the parachute cabin. However, due to the small size of the part during production, the traditional p...

Problems solved by technology

In mass production, the number of rope head materials wasted by this production process accounts for more than 35% of the total material quantity, which not only causes a huge waste of raw materials, but also because this kind of rope is made of special textile materials, it is expensive and causes business costs. stay high

In addition, the traditional processing method requires relatively high requirements when the connecting collar is ironed off the head and tail of the rope at the final hot spot cutter, and the operation still has certain difficulties.
