Description

Punching machine for pull rod of suitcase

Technical Field

The utility model belongs to the technical field of case and bag processing, a piercing press is related to, especially a piercing press for travelling basket pull rod.

Background

Early luggage cases were made of wood or other bulky materials, which tended to be lighter and lighter in weight, hard plastic or cloth, as air travel became popular. Most models are also provided with built-in small wheels, the luggage case can be conveniently pulled by using a pull rod, and the luggage case with 4 small wheels can be easily pushed on a flat ground without labor except that the luggage case can be rotated by 360 degrees in 2010.

In addition, the luggage may be divided into a hard-shell luggage and a soft-shell luggage according to the outer shell. The hard-shell luggage case is relatively resistant to falling and is suitable for luggage needing more protection. Soft shell cases are generally lighter in weight and more flexible in capacity than harder shell cases. However, the zipper of soft shell luggage cases is more likely to pop open due to excessive contents.

A trolley case refers to a luggage case having a pull rod and rollers. It is widely used because of its convenient use. Meanwhile, the draw-bar box is provided with a draw bar, a single-tube draw bar and a double-tube draw bar, and a tube of the draw bar is divided into a square tube and a round tube, so that the draw-bar box is convenient to drag when walking, and the burden is greatly reduced. The draw-bar box is generally made of PC material or ABS, and 100% PC material density is higher than ABS by more than 15%, so that it is not necessary to be very thick to achieve the effect of firmness, and the weight of the box body can be reduced, so called light weight.

Wherein the pull rod is an indispensable part on most travelling suitcases, need punch a hole on the pull rod when the pull rod of production travelling basket, because the square pipe that the pull rod adopted is hollow, adopt elastic gasket to carry out the centre gripping to square pipe usually when centre gripping location square pipe, but when punching a hole to square pipe, the pipe wall application of force of punching head from outside to inside to square pipe can lead to square pipe to take place the skew and lead to punching a hole quality not up to standard. And current pull rod piercing press can only punch to one side of steel pipe usually once, but the pull rod needs punch at bilateral same position, sets up the structure through the through-hole and makes the pull rod can vertically go up and down, so punch to the pull rod unilateral and have the problem that work efficiency is low, and pull rod raising and lowering functions's realization needs the punching of pull rod both sides to be in on the same straight line, probably still can appear when punching to the pull rod unilateral and punch the position deviation and lead to the unable problem of using of pull rod.
