Abstract

An efficient wearable core frame belongs to the porous brick molding field, comprises a core rod and a cutter rest and is characterized in that the core rod is mounted with a hard wearable round cover; a hard wearable V-shaped piece is fixed at the side of the cutter rest facing mud. The utility model can improve the wearability of the core frame and reduces the time for demounting a machine opening. The core frame is made by compounding high hard wearable material and common steel and iron, and the service life can be forty to sixty days. Because the wearability and the friction coefficient are far less than the steel sheet with coarse surface, the service life of the core frame is improved approximately twenty times. At the same time, the resistance is reduced, and the efficiency is improved. The quantity of hollow adobes produced per minute is improved from 120 pieces to 198 pieces. The dryness crack of adobe extruded by the utility model is reduced obviously, which improves the quality of the product. The production efficiency of a brick manufacturing system is improved by 40 percent, the electrical waste per minute is reduced by more than 30 percent, and the production cost is reduced by more than 15 percent.

Description

High-efficiency abrasion-proof core frame

Technical field

The utility model belongs to the porous brick forming field, is a kind of wear-resisting accessory of vacuum extruder.

Background technology

Implement industrial policy in China, in the process of advance walling innovation and building energy conservation, building a conservation-minded society, large quantities of gangues, flyash sintered perforated brick enterprise are constructed and put into operation one after another comprehensively.Producing porous brick needs special-purpose make-up machine, extrudes after raw material all needs the process fragmentation and stirs in the brickmaking technology.In the existing porous brick make-up machine, consumable accessory is a lot, and changes the core frame that the most frequent parts promptly are positioned at the machine mouth, is basically just to be ground away in 1-3 days.The consuming cost that causes owing to wearing and tearing is about about 0.02-0.05 unit/piece brick.Allow numerous brick fields and brick machine factory " the core frame " that be arranged in the machine mouth of headache the most, use manganese steel to be welded usually, big to the resistance of pug, its life-span is generally about 1-3 days.Not only the machine mouth to be unloaded when changing the core frame, also welded and installed, adjustment again, not only had a strong impact on porous brick production efficiency, increased the accessory cost, but also restricted the upgrading of China's brick machine industry.

The utility model content

The technical problem that the utility model solved is: a kind of high-efficiency abrasion-proof core frame is provided, can improves the service life of core frame greatly.

The technical scheme that its technical problem that solves the utility model adopts is: design a kind of high-efficiency abrasion-proof core frame, comprise core bar and knife rest, it is characterized in that on the core bar suit hard, wear-resistant circle cover, knife rest meet on the mud face fixedly hard, wear-resistant V-type part.

The utility model is pasted the hard, wear-resistant sheet on other faces of knife rest.Hard, wear-resistant circle cover can adopt ceramic ring, the densely covered from top to bottom ceramic ring of core bar; Hard, wear-resistant circle cover also can adopt earthenware.

The beneficial effect that the utility model had is:

1. can improve the wearability of core frame greatly, reduce the time of demountor mouth; Utilize high hard high-abrasive material and the compound core frame of making of common iron and steel, the life-span can reach 40-60 days; Because its wearability height, coefficient of friction are little, so the life-span of core frame has been improved nearly 20 times.Reduce resistance simultaneously, improved efficient; Per minute goes out hollow brick blank and brings up to 198 by original 120.

2. obviously reduce in the brick bat drying crack of adopting the utility model to extrude, and has made on the product quality class.Brick making system production efficiency has improved 40%, and the per minute power consumption has descended more than 30%, and production cost reduces more than 15%.

3. the size of former core frame can not become, and makes maintenance cost and reduces, and is convenient to promote.

Description of drawings

Fig. 1 is the structure chart of the utility model embodiment;

Fig. 2 is the A-A structural representation of Fig. 1;

Fig. 3 is that the B of Fig. 2 is to structural representation;

Among the figure: 1. nut, 2. core print, 3. ceramic ring, 4. core bar, 5. knife rest, 6.V type potsherd.

The specific embodiment

The core frame generally is made up of knife rest 5 and core bar 4, core print 2, and core print 2 is pressed on the core bar 4 by

nut

1,4 suit ceramic rings 3 (also can adopt long earthenware) on the core bar.Paste V-type potsherd 6 at " meeting the mud face " position of knife rest 5, V-type potsherd 6 " rides over " on the knife rest 5, and concrete combination is with reference to structure shown in Figure 2.The position that above-mentioned " meeting the mud face " position just most is vulnerable to wear and tear.In order further to improve the service life of knife rest 5, hard wear-resistant material sheets such as potsherd or alloy sheet are also pasted on other surfaces of knife rest 5.

Utilize inductile industrial residues such as gangue, flyash to be raw material, through broken, enter two-stage vacuum after adding processing such as water stirring, heavyization and mould extruder firmly.When pug enters the machine mouth, between " meeting the mud face " position of knife rest 5 and the surface of surfaces externally and internally and core bar and the pug very big friction is arranged, thereby the frictional resistance maximum at these positions, also be the most easy to wear.The potsherd owing on the surface of knife rest 5 position of " meeting the mud face " and surfaces externally and internally and core bar, all applied ointment or plaster, thereby the wearability of core frame improves greatly, simultaneously because the coefficient of friction of pottery or alloy is very little, so behind this core of employing frame, production efficiency obviously improves.Even the wearing and tearing of part of V type potsherd only need to change these potsherds and get final product, need not be whole changing knife frame.Pug enter behind the knife rest 5 also can with the inside and outside wall friction of knife rest 5, thereby the hard, wear-resistant potsherd of all applying ointment or plaster on the inside and outside wall of knife rest 5.When pug when core bar 4 flows with the bigger friction of core bar 4 generations, for this reason, 4 suit ceramic rings 3 on the core bar, ceramic ring 3 can improve wearability greatly, has further reduced frictional resistance, has prolonged the service life of core bar 4.
