Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 3 and Figure 4, the invention provides one to pressurize up and down refractory material hydraulic forming machine, comprise base 13, be fixedly connected on four root posts 14 of base corner, be fixedly connected on the back timber 15 at column 14 top and be fixedly installed on the upper cylinder 16 of back timber central authorities, described base 13 is fixedly installed lower oil cylinder 12, and the upper end of lower oil cylinder 12 is connected with lower moved cross beam 5, and lower moved cross beam 5 four jiaos is set in the bottom of column 14 and can moves up and down along column under the promotion of lower oil cylinder 12; The middle part of described column is fixedly installed intermediate beam 4, and the center of intermediate beam 4 is fixedly installed funnel shaped mold cavity 3; The lower end of described upper cylinder 16 is fixedly installed moved cross beam 2, and the corner of described upper moved cross beam is set in the top of column 14, and upper moved cross beam 2 can move up and down along column under the driving of upper cylinder 16, is fixedly installed patrix 1 in the middle part of upper moved cross beam 2.Thus, in use, upper and lower mould can be realized and pressurize to while material in mold cavity, thus effectively ensure to achieve two-way compacting, thus significantly reduce the density variation of goods along short transverse.
Wherein, the center of lower moved cross beam 5 upper surface is fixedly installed cushion block 6, cushion block 6 and counterdie pressure-bearing connect handle 10 and are fixedly connected with, and the top that counterdie pressure-bearing connects handle 10 is fixedly installed counterdie 9, and described cushion block 6, counterdie pressure-bearing connect the cylinder type that handle 10 and counterdie 9 are hollow; The center of lower moved cross beam is run through up and down and is provided with oil cylinder 8 of loosing core, loose core in oil cylinder and be arranged with piston 11, the piston rod 111 top stationary core rod 7 of piston, piston rod 111 and plug 7 are through described cushion block 6 and counterdie pressure-bearing connects handle 10 and counterdie 9 extends upwardly to mold cavity 3 upper surface.Thus can automatic core-pulling be realized when production is free goods, realize automation mechanized operation, reduce labor intensity, enhance productivity.Described patrix 1, mold cavity 3, cushion block 6, plug 7, oil cylinder 8 of loosing core, counterdie 9, counterdie pressure-bearing connect the central shaft of handle 10 and piston 11 on same straight line, power under duty also can be acted on point-blank, thus avoid the loss of energy in equipment running process.The outer diameter length of plug 7 is identical with the interior electrical path length of counterdie 9, ensureing that plug can drop out freely in avoiding material by the space in the middle of counterdie and plug while counterdie, cause the waste of material and the pollution of equipment, and when counterdie pressurizes to material, make the inside and outside uniform force of material, and then make goods even density diametrically.Plug 7 and the height sum of piston 11 are less than the height sum that loose core oil cylinder 8 and counterdie pressure-bearing connect handle 10 and cushion block 6, making plug 7 can be retracted to pressure-bearing completely connects in handle 10, the height of plug 7 is greater than the height of mold cavity 3, plug 7 is independent of one another with mold cavity 3, to make in forming process plug 7 can freely-movable, and the patency of the centre bore of the goods with holes produced can be ensured.Described hydraulic forming machine also comprises can metal-back 32 matching used with it and upper reinforced cover 34, thus realizes the one-body molded of band shell refractory material.
As shown in Figure 2, present invention also offers a kind of band shell refractory material one-step moulding method using above-mentioned refractory material hydraulic forming machine, comprise the following steps:
Step 1, places in the mold cavity 3 of refractory material hydraulic forming machine in advance by metal shell 32;
Step 2, is incorporated on mold cavity 3 by upper reinforced upper shield;
Step 3, drops into raw material in mold cavity 3, runs the described refractory material hydraulic forming machine that pressurizes up and down;
Step 4, takes out goods after the demoulding.
Further, in step 4, the goods of gained no longer need drying and processing.
Further, the outer surface of described metal shell and the inner surface of mold cavity 3 adapt, and mold cavity 3 lower internal diameter is less than metal-back 32 lower internal diameter; Upper reinforced cover 34 internal diameter is less than the upper internal diameter of metal-back 32, thus is fixed in mold cavity by metal-back better, avoids the movement of metal shell in equipment running process.
Before device start, patrix 1 is in extreme higher position, and the piston 11 of oil cylinder 8 of loosing core drives plug 7 to reach the feed location concordant with mold cavity 3 upper surface, and oil cylinder 12 drives counterdie 9 to return to mold cavity 3 lower limit charging position.Box hat 32 is put into mold cavity and is fixed by the reinforced cover 34 being fixedly connected on mold cavity 3 upper end.After starting auto-programming, patrix 1 is automatically pressed down to the patrix predeterminated position in mold cavity 3 under master cylinder promotes, and patrix predeterminated position is positioned at 0-10mm above shaping end position; Oil cylinder 12 promotes counterdie 9 and rises to counterdie predeterminated position, and counterdie predeterminated position is positioned at 0-20mm below shaping end position; Patrix 1, counterdie 9 desired location that move toward one another is extremely respective simultaneously, thus achieve two-way compacting.Meanwhile loose core the piston 11 of cylinder 8 because plug 7 creates certain contractile motion by the press power effect of patrix 1; Counterdie 9 to have moved up corresponding distance relative to plug 7, thus furthermore achieved that two-way compacting.After having suppressed, patrix 1 rises to upper limit position; Oil cylinder 12 promotes counterdie 9 and to move up together with loose core oil cylinder 8 and goods 0-20mm, and object is by goods first upwardly once, goods external diameter and mold cavity inner surface is departed from and reduces the enclasping force of goods to plug afterwards; The piston 11 of oil cylinder 8 of loosing core drives plug 7 to move downward, thus is extracted out completely from goods by plug 7; Oil cylinder 12 promotes counterdie 9 and goods until it exceeds the upper surface (i.e. demoulding end position) of mold cavity 3; Manually take goods away; Counterdie 9 drops to lower limit charging position under the drive of oil cylinder 12; Cylinder 8 of loosing core stretches out piston rod 11 and plug 7 is released the charging position concordant with mold cavity 3.So far, each parts of refractory material hydraulic forming machine get back to initial position, and obtain one-time formed band shell refractory material.
Band shell refractory material one-step moulding method of the present invention, simplify band shell refractory material producing shaped operation length, reduce the generation of artificial input and artificial mass defect, eliminate the use of refractory clay, in submission efficiency, while cost-saving, ensure that the quality of product.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
