Description

Background

In the field of building production, high efficiency and energy conservation are always one of core targets pursued by industry. In order to achieve the aim, scientific researchers continuously explore and innovate, and a novel energy-saving building material is developed. The material is prepared by improving the traditional clay bricks. Specifically, by incorporating into the clay a proportion of industrial waste materials including, but not limited to, waste refractory brick pellets, fly ash, hearth slag, stone dust, and the like. After special process treatment, the waste materials are fully fused with clay, so that a brand new building material is formed.

The patent with publication number CN210820080U discloses a forming device for producing building materials. When the device is used, the operation flow is relatively complicated. When the forming device is used, the upper pressing plate needs to be removed firstly, and then the connecting rod, the fixing sleeve and the supporting plate are adjusted to the proper positions through the fixing ring, so that the forming frame can be completely placed on the connecting rod and the supporting plate. Then, the jack pushes the lower hydraulic rod to a proper position of the forming frame, and at the moment, concrete starts to be filled into the forming frame. When the concrete filling is finished, the upper pressing plate is placed in a forming frame filled with the concrete, and the upper hydraulic rod is started to extend downwards. When the upper hydraulic rod extends downwards to the longest, the lower hydraulic rod is also required to be extended, so that the whole concrete mould is more compacted, and the forming effect is ensured.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

According to the energy-saving building material production mould provided by the application, industrial waste is used as a raw material for manufacturing a brick body, so that the waste plays a role in reinforcing a brick blank, and the compressive strength of the brick is improved.

In use, the basic structure and plasticity of the brick is provided depending on the clay as the main raw material. The waste materials (such as waste refractory brick particles, fly ash, furnace bottom slag, stone powder and the like) with a certain proportion are crushed and mixed with clay to form a blank with certain plasticity. The manufactured material is then fed into the production mould according to the application for shaping.

In particular, as can be seen in connection with fig. 1 and 2, the whole device comprises two main parts, an upper mould 1 and a lower mould 2. In the application process, the upper die 1 can be fastened on a press by using the hanging lug holes reserved at the top, and the upper die 1 is driven to move up and down by using the press, so that the upper die 1 and the lower die 2 are mutually close, namely, the die assembly process is realized.

The four corners on the surface of the lower die 2 are respectively provided with a guide piston assembly 3 which is fastened and installed by using a flange, and a piston rod in the guide piston assembly 3 is fixedly connected with the upper die 1, so that the design can ensure that only the upper die 1 and the lower die 2 can move up and down relatively, and the extension length of the guide piston assembly 3 is limited, so that after the piston rod extends out of the guide piston assembly 3 completely, the upper die 1 which continues to move up can drive the lower die 2 to move up by using the guide piston assembly 3. A return spring 301 sleeved on the outer side part of the piston rod is arranged between the top end of the guide piston assembly 3 and the bottom surface of the upper die 1, and the lower die 2 is forced to always move away from the upper die 1 under the pushing of the elastic force of the return spring 301 in a normal state.

The bottom of the upper die 1 is provided with a supporting frame 4 which is guided and installed by a plurality of telescopic rods, and as can be seen from fig. 6, a demoulding spring 401 positioned at the outer side part of the telescopic rods is connected between the supporting frame 4 and the upper die 1. Normally, the supporting frame 4 is pushed by the elastic force of the demolding spring 401 and guided by the telescopic rod, so that the telescopic rod moves downwards and is promoted to extend to the longest. Moreover, a plurality of pressure heads 5 are fixedly arranged at the bottom of the support frame 4 by bolts, and six pressure heads 5 are taken as an example in the application, so that six brick bodies can be manufactured simultaneously after one-time die assembly. In practical application, the number of the pressing heads 5 is not limited to this, and can be adjusted adaptively according to practical needs.

Correspondingly, as can be seen from fig. 3, the surface of the lower die 2 is provided with a molding die cavity corresponding to the pressing head 5, namely, as shown in a part A in fig. 3, when the upper die 1 descends, the pressing head 5 is used for pressing the molding die cavity, so that materials in the molding die cavity are extruded and molded, and the manufacturing of a plurality of energy-saving clay bricks is realized by one-time die assembly.

In order to facilitate the removal of the manufactured brick body from the molding cavity, as can be seen in fig. 1 and 5, a synchronous piston cylinder 7 is arranged on one side of the surface of the lower die 2 through bolt fastening, and an inner cylinder 701 coaxially arranged with the inner cylinder is fixedly connected to the top of the inner side of the synchronous piston cylinder 7. Wherein, the piston rod of the synchronous piston cylinder 7 is hermetically sleeved with the inner side of the inner cylinder 701. As can be seen from fig. 5, the inner cylinder 701 communicates with the inner space of the synchronous piston cylinder 7 by means of a bottom. When the piston rod is positioned in the inner cavity of the inner cylinder 701, the cavity of the inner cylinder 701 positioned above the piston rod is separated from the inner cavity of the synchronous piston cylinder 7, the electromagnetic valve 702 for controlling the sealing cavity to be communicated with the inner cavity of the synchronous piston cylinder 7 is fixedly arranged at the top of the outer side of the synchronous piston cylinder 7, and when the electromagnetic valve 702 is electrified, the channels of the inner cavity of the inner cylinder 701 and the inner cavity of the synchronous piston cylinder 7 can be opened, so that the mutual flow of hydraulic oil between the two is realized.

In practical application, it can be seen from fig. 5 that an oil filling port is formed at the top of the synchronous piston cylinder 7, and the oil filling port can be elastically sealed and can also be connected with an oil tank. Hydraulic oil can be added into the inner cavity of the synchronous piston cylinder 7 by using the oil filling port.

Normally, the upper die 1 is fixed on a press, and when the upper die 1 is lifted by the press, the lower die 2 can be driven to synchronously lift according to the guide piston assembly 3, and at this time, the piston rod of the synchronous piston cylinder 7 is positioned at the top of the inner cavity of the inner cylinder 701, namely, the position shown in fig. 5.

When the brick body is manufactured, a flat plate needs to be placed in the area under the lower die 2 and the forming die cavity, the formed brick body is convenient to stack on the flat plate, and the flat plate can be carried by using equipment such as a forklift. After that, when the press pushes the upper die 1 downward, the lower die 2 at the bottom thereof comes into contact with the flat plate at first.

Raw materials for preparing the brick body are added into a molding die cavity, and as the upper die 1 continuously descends, the upper die 1 and the guide piston assembly 3 compress and store the restoring spring 301. In the process, the piston rod of the synchronous piston cylinder 7 synchronously descends, as can be seen from fig. 5, the check valve 703 is fixedly arranged at the bottom of the piston rod of the synchronous piston cylinder 7, the check valve 703 can realize the upward unidirectional flow of hydraulic oil in a cavity below, and the piston rod in the synchronous piston cylinder 7 is ensured to descend so as to be convenient for rapid downward movement.

As the upper die 1 drives the supporting frame 4 to continuously move downwards, the pressure head 5 on the supporting frame 4 is finally pressed in the forming die cavity. As the upper die 1 descends continuously, the pressure exerted by the ram 5 on the molding cavity increases continuously, and in this process, the support frame 4 compresses the stripper spring 401 synchronously until it compresses to the limit. Finally, as the ram 5 in the upper die 1 applies the required pressure to the molding cavity, the ejector spring 401 is compressed and the piston rod in the synchronized piston cylinder 7 has also been disengaged from the inner cylinder 701.

After the raw materials in the forming cavity are extruded and formed, the upper die 1 is driven to move upwards according to the press, at this time, the return spring 301 pushes the guide piston assembly 3 to move downwards along with the upper die 1 driving the piston rod in the synchronous piston cylinder 7 to move upwards and approach the bottom of the inner cylinder 701, so that the lower die 2 is forced to be still pressed on the flat plate. When the piston rod enters the inner cylinder 701, the hydraulic oil in the inner cylinder 701 cannot be compressed, and the electromagnetic valve 702 is in a blocking state, so that the upper die 1 moves upwards to drive the lower die 2 to move upwards synchronously, but the pressure head 5 is pushed by the elastic force of the demoulding spring 401 at the moment to move downwards. As the lower die 2 continuously moves upwards, the pressing head 5 is pushed out of the forming die cavity by the elastic force of the demoulding spring 401, so that the brick body in the forming die cavity is conveniently demoulded. When the upper die 1 moves up to the top, the inner cylinder 701 is communicated with the inner cavity of the synchronous piston cylinder 7 according to the electromagnetic valve 702, hydraulic oil in the inner cylinder 701 flows into the inner cavity of the synchronous piston cylinder 7, is pushed by the return spring 301 to force the whole to return to the normal position, and waits for the next stamping forming.

The shaped green bricks are also subjected to drying treatment to remove excessive water. And then, placing the dried green bricks into a kiln for roasting. The roasting temperature and time need to be strictly controlled according to the raw material property and the product requirement. In the baking process, the clay and waste materials in the green bricks undergo physical and chemical changes to form the brick body with certain strength and durability. The firing temperature is usually set in the range of 950 ℃ to 1300 ℃ and the firing time is 20h to 24h.

The baked brick body is subjected to quality inspection, including indexes such as appearance quality, dimensional accuracy, compressive strength, water absorption rate and the like. And packaging qualified products, leaving the factory, and reworking or scrapping unqualified products.

In the second embodiment, since the brick body is further improved based on the first embodiment and the subsequent dimension inspection is needed, it can be seen from the above manufacturing process that the brick body is mainly pressed and formed in the forming die cavity, the formed dimension such as length and width is limited by the forming die cavity and is relatively stable, but the thickness and height direction of the brick body are influenced by the input amount of raw materials. The unstable input of raw materials is affected by various factors such as uneven mixing of raw material particles, inaccurate metering equipment, uneven feeding speed, etc.

In order to prevent such problems, as can be seen in fig. 2 and 3, the surface of the lower die 2 is movably provided with the dies 6, and the dies 6 are fixedly connected by using brackets, so that the dies 6 are forced to horizontally move along the surface of the lower die 2 by using the brackets. As shown in fig. 3, the mold 6 and the molding cavity are relatively offset after the mold 6 is moved to the left limit, and similarly, the molding cavity and the mold 6 are aligned after the mold 6 is moved to the right limit. Normally, as the surface of the lower die 2 is provided with the forming spring 602 by using the base, the end part of the forming spring 602 is propped against the die 6, and the die 6 and the forming die cavity are always in an aligned state under the pushing of the elastic force of the forming spring 602.

As can be seen from fig. 1, 4 and 5, the side of the lower die 2 is provided with an adjusting piston cylinder 8 fixedly mounted through a hydraulic cylinder frame, and the adjusting piston cylinder 8 is communicated with the inner cavity of the inner cylinder 701 by utilizing a hydraulic oil pipe. The connecting frame 10 is fixedly arranged at the outer side part of the piston rod of the adjusting piston cylinder 8, the connecting frame 10 is fixedly connected with the bottom of the section mould 6, and when the piston rod of the adjusting piston cylinder 8 performs telescopic movement, the section mould 6 can be driven to perform left-right reciprocating movement by the connecting frame 10. Meanwhile, as can be seen from fig. 2,3 and 6, the end of the support frame 4 has a locking frame 402 fastened by bolts, and the locking frame 402 has an "L" shape in cross section. Correspondingly, the bottom of the upper die 1 is movably provided with a locking slide seat 12, and a locking spring 120 is connected between the locking slide seat 12 and the upper die 1, and the locking slide seat 12 is forced to move towards the locking frame 402 by the elastic force of the locking spring 120. The side shape of the locking slide seat 12 is approximately Z-shaped, and the bottom is provided with an inclined plane, so when the locking slide seat 12 moves above the supporting frame 4, the supporting frame 4 pushes the locking frame 402 to move towards the locking slide seat 12, the ascending locking frame 402 can push the locking slide seat 12 to compress the locking spring 120 according to the inclined plane, and when the locking frame 402 passes over the locking slide seat 12, the locking slide seat 12 is pushed by the elastic force of the locking spring 120 to move below the locking frame 402, so that the locking frame 402 is limited to descend. Moreover, the bottom of the locking slide seat 12 is fixedly provided with a shifting telescopic rod 11, the bottom end of the shifting telescopic rod 11 is movably arranged on the surface of the lower die 2, as shown in fig. 3, after the die 6 moves to the left limit, a bracket on the die 6 can squeeze the shifting telescopic rod 11, and the locking slide seat 12 can synchronously compress the locking spring 120 by utilizing the transmission of the shifting telescopic rod 11.

In practice, the forming spring 602 normally pushes the die 6 to the right limit, and at the same time, the locking spring 120 pushes the locking slide 12 to the right limit.

As shown in fig. 2, fig. 4 and fig. 5, when the press drives the upper die 1 downward, the lower die 2 is first pressed onto the flat plate. At this time, since the die 6 and the molding cavity are aligned, the raw material can be directly fed into the die 6. After the raw materials are conveyed, the raw materials are pressed downwards through the upper die 1. In accordance with the first embodiment, when the upper die 1 pushes the ram 5 down, the ram 5 is pressed into the die 6 at this time, and the ram 5 performs the press molding of the raw material in the die 6 and the molding cavity simultaneously. After the downward movement of the ram 5 is blocked, the support frame 4 will squeeze the demolding spring 401, so that the support frame 4 is relatively close to the upper mold 1. In this process, the support 4 relatively approaches the locking slide 12, and pushes the inclined surface of the locking slide 12 by using the support 4, so that the locking slide 12 moves leftwards and presses the locking spring 120, and when the support 4 continues to move upwards and passes over the locking slide 12, the locking slide 12 pushed by the elastic force of the locking spring 120 moves below the locking frame 402, thereby limiting the downward movement of the support 4.

With the continuous depression of the upper die 1, the ram 5 applies a preset pressure to the die 6 and the molding cavity, which pressure is adjusted in accordance with the press. After compression molding, the raw materials in the inner cavity of the die 6 and the molding cavity form a whole brick body.

When the upper die 1 is reset upward, the return spring 301 pushes the guide piston assembly 3 downward, so that the lower die 2 is still pressed against the flat plate. When the piston rod of the synchronizing piston cylinder 7 enters the inner cylinder 701, the hydraulic oil in the inner cylinder 701 is pressed and the piston rod of the adjusting piston cylinder 8 is forced to push out. The pushed-out piston rod drives the connecting frame 10 to move leftwards, so that the die 6 and the forming die cavity are forced to move relatively, and the brick body is cut off by utilizing the relative shearing of the die 6 and the forming die cavity until the die 6 moves to the left limit. At this time, the height of the brick body is consistent with the height of the molding cavity, namely the thickness of the molded brick body is consistent. When the die 6 is completely separated from the molding cavity, the bracket on the die 6 can be propped against the shifting telescopic rod 11 and push the shifting telescopic rod to move leftwards in the left moving process of the die 6, and after the die 6 and the molding cavity are separated, the shifting telescopic rod 11 also drives the locking sliding seat 12 to be far away from the supporting frame 4, so that the movement restriction on the supporting frame 4 is relieved. The support frame 4 is pushed by the elasticity of the demolding spring 401 to enable the pressing head 5 to move downwards, the pressing head 5 is propped into the molding die cavity, and after the upper die 1 drives the lower die 2 to move upwards, the pressing head 5 pushes out a brick body in the molding die cavity until the upper die 1 moves upwards to the top limit, the electromagnetic valve 702 is opened, hydraulic oil in the inner cylinder 701 flows back into the inner cavity of the synchronous piston cylinder 7, and the return spring 301 pushes the guide piston assembly 3 to move downwards until the whole device is restored to the initial state.

From this, it can be seen that, according to the second embodiment, the building material can be pressed into a brick body with a larger thickness according to the mould 6, and before the brick body is demolded, the brick body is cut according to the mould 6, so that the thickness and the size of the brick body finally output from the molding cavity are ensured to be consistent.

As a supplement to the second embodiment, as can be seen from fig. 2 and 4, the piston rod of the adjusting piston cylinder 8 is fixedly provided with an anti-reverse seat 9 located at one side of the connecting frame 10, the shape of the anti-reverse seat 9 is conical, and the anti-reverse seat 9 is coaxially arranged and connected with the piston rod of the adjusting piston cylinder 8, so that the anti-reverse seat 9 can be driven to synchronously move left and right when the piston rod moves. Correspondingly, the bottom of the lower die 2 is movably provided with a fork frame 901 in place, the fork frame 901 in place is U-shaped, and a piston rod of the adjusting piston cylinder 8 is positioned at the inner side of the U-shaped. The design has the advantages that when the upper die 1 drives the pressing head 5 to finish the die pressing and up, the piston rod in the adjusting piston cylinder 8 is pushed to the left, when the anti-reverse seat 9 moves to the left, the inclined surface on the outer side of the anti-reverse seat 9 can enable the in-place fork frame 901 to move upwards, when the anti-reverse seat 9 completely passes over the in-place fork frame 901, the in-place fork frame 901 moves to the cone bottom plane of the anti-reverse seat 9 due to the downward movement of gravity, and at the moment, the locking slide seat 12 also releases the limit on the locking frame 402. The support frame 4 is pushed down again by the demoulding spring 401, so that the pressing head 5 pushes the brick body in the forming die cavity downwards. In this process, the in-place fork 901 always locks the anti-reverse seat 9, so that the anti-reverse seat 9 cannot be forced to move to the right, and therefore, even if the upper die 1 is completely moved to the top in the following process and the whole is reset, the die 6 is forced to be staggered relative to the molding cavity all the time due to the movement restriction of the in-place fork 901 on the anti-reverse seat 9. As can be seen from the second embodiment, after the brick body in the molding cavity is cut off by the mold 6, part of raw materials can remain in the mold 6, and are limited by the fork 901 and the anti-reverse seat 9, so that the mold 6 is forced to be always staggered relative to the molding cavity in a normal state, and the problem that the residual raw materials in the mold 6 leak downwards from the molding cavity is avoided.

Moreover, when the brick is prepared again, as the lower die 2 moves down and props against the flat plate first, as can be seen from fig. 2, the in-place fork 901 stretches into from the bottom of the lower die 2 in a normal state, when the lower die 2 moves down and presses on the flat plate, the flat plate can push the in-place fork 901 to move upwards and release the movement restriction on the anti-reverse seat 9, and the subsequent die 6 can lead the die 6 to be aligned with the molding cavity again under the pushing of the elastic force of the molding spring 602, so that the residual raw materials in the die 6 can be reused. The in-place fork 901 can detect whether a flat plate exists at the bottom of the lower die 2, and when the bottom of the lower die 2 is guaranteed to exist, the in-place fork 901 can align the die 6 with the forming die cavity, so that subsequent brick preparation work is completed.

As can be seen in connection with fig. 2-4, the sides of each mould 6 are provided with a buffer vessel 601 mounted by means of bolting, the buffer vessel 601 being in a clearance fit with the ram 5, which has the advantage that the buffer vessel 601 and the moulding cavity can be aligned when the mould 6 is displaced from the moulding cavity, i.e. the situation shown in fig. 3. When the locking slide seat 12 releases the motion restriction of the locking frame 402, the demoulding spring 401 can quickly push the pressing head 5 to move downwards, but at the moment, after the pressing head 5 enters the buffer cylinder 601, air flow in the buffer cylinder 601 flows out along a gap between the pressing head 5 and the buffer cylinder, so that the damping on the descending motion of the pressing head 5 is realized, and the problem that the pressing head 5 directly collides with a brick body in a molding die cavity to cause the deformation of the brick body due to the overlarge instantaneous impact is avoided. Moreover, because the plurality of pressure heads 5 synchronously move downwards, the damping cooperation between one pressure head 5 and the buffer cylinder 601 can influence the whole descending speed, so that the whole pressure head 5 can decelerate downwards, and the problem that the local pressure head 5 still collides with a brick body due to too fast descending is avoided.
