A batch opening device for bellows

Abstract

The invention relates to a batch opening device for corrugated pipes, which includes a base plate, a fixing plate, a hole opening mechanism and a fixing mechanism. The upper end surface of the base plate is equipped with a fixing plate, and the fixing plates are symmetrically arranged in a left and right structure, and the left and right are opposite to each other. Between the fixed plates, a hole opening mechanism and a fixing mechanism are sequentially arranged from top to bottom. The present invention adopts the design concept of multiple sets of drill bits to simultaneously open holes for batches of corrugated pipes. The hole opening mechanism set by this device can realize all The function of synchronous work of the drill bit can achieve the effect of batch opening of bellows, and at the same time, the function of limiting and fixing the bellows can be realized through the fixing mechanism, thereby enhancing the effect of opening holes.

Description

technical field [0001] The invention relates to the field of corrugated pipes, in particular to a batch opening device for corrugated pipes. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and expansion. The wall of the bellows is thin and the sensitivity is high. The measuring range is tens of Pa to tens of MPa. Displacement can be generated under the action of pressure, axial force, lateral force or bending moment. Bellows are widely used in instruments and meters. The main purpose is as a measuring element of pressure measuring instruments to convert pressure into displacement or force. It can be used as a sealing isolation element to separate two media or prevent harmful fluids from entering the measuring part of the equipment. It can also be used as a compensating element to compensate the temperature error of the instrument by using its volume variability. Elasti...

Problems solved by technology

[0003] 1. Due to the long length of the corrugated pipe, the existing corrugated pipe opening device cannot realize the function of batch opening well. If the bellows are to be opened in batches, it will take a lot of manpower to limit and guide it And the storage work after opening, thus reducing the batch opening efficiency of bellows;

[0004] 2. During the process of opening the bellows, due to its own elasticity, it is easy to shift, resulting in poor opening effect, and the existing bellows opening device is only suitable for one specification of bellows opening and can only Holes of one aperture are drilled, thereby reducing the degree of use of the device and the efficiency of batch opening of corrugated pipes
