Description

Pipe end face grinding machine

Technical Field

The invention relates to a pipe body end face grinding machine.

Background

At present, there are two main methods for manufacturing single-layer glass cups, one is a kiln production method, i.e. a method of pressing or blowing a mould by using a punch or using the pressure of air pressure to force high-temperature molten glass to be formed in the mould. The other method is a cutting production method, which is divided into two methods, one method is an integral forming method, namely, a glass tube is firstly manufactured, the glass tube is used as a raw material, two ends of the glass tube are clamped and supported and synchronously rotated, the middle part of the glass tube is locally heated by flame until the glass is softened, the heating temperature is 820-1500 ℃, a blade made of a heat-resistant material with the thickness smaller than the width of a heating region and without affinity with the glass is used for slowly cutting from the middle of the heating region, and one glass tube is gradually formed into two glass cups with cup bottoms; the method has high manufacturing efficiency and low production cost, and in addition, the glass has good forming quality. The other method is an adhesive bonding method, namely, the glass tube with two open ends is manufactured, when the glass tube is manufactured, the bottom of the glass tube is cut by adopting a cutting process, then the glass tube is ground flat, after the glass tube is ground flat, the bottom of the glass tube is adhered to the bottom of the glass tube by using adhesives such as glass cement, and finally the glass cup is formed.

In the grinding process after the glass tube is cut, the bottom of the glass tube is ground by using a grinding wheel in the prior art, but because the bottom of the glass tube needs to be ground by a single grinding wheel, manual clamping grinding is mostly adopted in the prior art, and the labor efficiency is very low; there is also a grinding machine which uses a gripper to grip a glass tube, uses a conveyor chain to transport a plurality of grippers, and then grinds the glass tube in the gripper one by one, which has a disadvantage in that the gripper and the distance between the conveyor chain and the grinding wheel need to be very precise, thereby frequently causing quality accidents and breakage accidents in the grinding process, resulting in low yield and low labor efficiency.
