Embodiment 1

[0015] Prepare a glass mat 1 with an outer diameter of Φ1130 mm, an inner hole of Φ570 mm, and a height of 136 mm.

[0016] 1. Lajin preparation. The hemp ropes of Φ8mm-Φ10mm are used for the ties, and the hemp ropes 2 for the circumferential ties are placed at the inside of the size of the glass pad 1, and the outer diameter is 1 / 4 of the wall thickness. Tie a buckle 4 every 120mm; then according to the laying distance of the two circumferential tendon hemp ropes 2, determine that the length of the radial tendon hemp rope 3 is 210mm and tie a buckle 4 at both ends respectively.

[0017] 2. When making a glass mat: Take 130 kg of glass powder, add 9 kg of water glass to the glass powder, stir and mix evenly, pour the mixed material into the cavity of the glass mat mold, and when the pouring height reaches 56mm, Place the hemp rope, press the prepared hemp rope figure 1 The position is placed well, that is, two circles of circumferential tension hemp rope 2 are placed at 1 / 4...

Embodiment 2

[0019] Prepare a glass mat 1 with an outer diameter of Φ1250 mm, an inner hole of Φ800 mm, and a height of 112 mm.

[0020] 1. Lajin preparation. Cotton ropes of Φ8mm-Φ10mm are used for the tension, and the circumferential cotton tension rope 2 is placed on the inside of the size of the glass mat 1, and the outer diameter is 1 / 3 of the wall thickness. The two circumferential tension cotton ropes 2 are 4200mm and 3325mm respectively. Tie a buckle 4 every 150mm; then according to the placement distance of the two circumferential tension cotton ropes 3, determine that the length of the radial tension cotton rope 3 is 185mm and tie a buckle 4 at both ends respectively.

[0021] 2. When making glass mat 1, take 150 kg of glass powder, add 10.5 kg of water glass to the glass powder, and stir Mix evenly, pour the stirred glass powder into the cavity of the glass mat mold, when it reaches 56mm, put the prepared cotton rope according to the figure 1 Placement, that is, place two circ...

Abstract

The invention relates to a glass cushion and a preparation method, belonging to the technical field of metal extrusion. A circumferential lacing wire and a radial lacing wire are arranged at the middle part of the glass cushion and are respectively provided with a button, two circles of circumferential lacing wires are respectively arranged near the edge of the inner diameter and the edge of the outer diameter of a mold cavity of the glass cushion, radial lacing wires are radially arranged between the two circles of circumferential lacing wires per 25-35 degrees, and buttons at both ends of the radial lacing wires are arranged out of the two circumferential lacing wires. In the preparation method, a mode of adding the lacing wires is adopted, the lacing wires are enabled to form a lacing wire net in a well shape and the intensity is strengthened. Particularly, the buttons are tied on the lacing wires so as to fulfill a function of pinning and efficiently pull the lacing wires and the glass cushion together, thereby preventing the glass cushion from crushing caused by stress in the placing process, solving the crushing problem in the transportation and placing processes of a large scale glass cushion and also lowering the reject rate of the glass cushion. In addition, the lacing wires are woven by hemp ropes, lace cords, chemical fiber ropes and the like, and are decomposed through combustion under high temperature without influencing the lubrication effect of the glass cushion at all.

Description

technical field [0001] The invention relates to a glass mat and a preparation method, belonging to the technical field of metal extrusion. Background technique [0002] The lubrication of the extrusion die during the extrusion process usually adopts the method of pressing glass powder into a glass mat. The glass mat prepared by this method is fragile and easy to make a small glass mat. The glass mat is placed between the extrusion die and the billet before extrusion, and the extrusion die is continuously moistened through the continuous softening of the glass mat. In actual production, if the glass pad is pressed too hard, the lubrication effect will be affected; otherwise, the glass pad will be fragile. Especially for large glass mats with a diameter of ≥700mm and a weight of ≥100Kg, under the condition of ensuring the lubrication effect, how to prevent it from being broken during the process of clamping and placing with equipment is a practical problem that needs to be ca...
