Description

Technical Field

[0001] The invention relates to the technical field of cement fluidity experiments, in particular to a raw material fluidity experiment device for wet pressing cement products with complex shapes. Background Art

[0002] During the production and development of complex-shaped cement products produced by wet pressing, conducting raw material fluidity tests is crucial. Complex shapes, such as those with thin walls, deep cavities, and multiple corners, place extremely high demands on raw material fluidity. Insufficient fluidity can prevent the raw material from completely filling the mold cavity, while excessive fluidity can cause leakage through gaps in the mold during pressing. Experimentation can accurately determine the optimal fluidity parameters for the raw material, ensuring its compatibility with complex mold cavities and guaranteeing the integrity of the finished product.

[0003] Publication number CN103063546A discloses a cement testing device, specifically a cement fluidity rapid test plate for rapidly testing cement fluidity. The plate comprises a square transparent glass plate with at least four symmetrically radiating straight lines on the back of the test surface extending outward from the center of the glass. While basic fluidity testing using only the square transparent glass plate and the lines is incapable of simulating the sealing environment and pressing conditions of complex mold cavities, its adaptability is poor.

[0004] Publication number CN110108596B describes a cement mortar fluidity tester, comprising a jumping table and a cleaning device. The jumping table comprises a frame base, a cam, a first motor, a sleeve, a push rod, a fixed tabletop, and a jumping tabletop. The frame base consists of three vertical steel ribs fixed to a circular steel plate at 120 degrees, connected to the sleeve. The push rod is a cylindrical rod housed in the sleeve. This instrument primarily tests the fluidity of mortar on the jumping table. However, it lacks structural adaptability for complex mold cavities, automated sealing control, and mold cleaning features, making it difficult to accurately test the fluidity of complex-shaped cement products.

[0005] There is an urgent need for an experimental device that can achieve automated control and multifunctional assistance to fill the gaps in existing technology. Summary of the Invention

[0024] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-12 As shown, the present invention provides a raw material fluidity experimental device for wet pressing of complex-shaped cement products, including a digital display control panel 10, which serves as the core hub of overall operation and parameter regulation and controls the operation of each driving structure; the basic molding component is composed of an upper template 2 and a lower template 3 distributed above and below, and a number of side templates 1 are arranged between the two, which together enclose a mold cavity suitable for complex-shaped cement products, and the lower side edge of the upper template 2 is protruded with a pressing edge 201. When the side templates 1 are gathered and closed to abut against the upper template 2, the pressing edge 201 can limit the outward expansion direction of the side template 1, and the cross-sectional shape of the pressing edge 201 is trapezoidal.

[0026] A detachable forming plate is provided in the mold cavity and placed according to experimental needs for testing thin walls, deep cavities, corners, etc. A support frame 15 is provided on the outside of the side template 1, upper template 2 and lower template 3 to provide a stable structural support for the entire device and ensure the stable operation of each component during the experiment.

[0027] A first lifting drive structure and a second lifting drive structure are respectively provided on the support frame 15, wherein the first lifting drive structure is used to flexibly adjust the upper and lower heights of the upper template 2, and the second lifting drive structure is used to adjust the upper and lower heights of the lower template 3. The second lifting drive structure adopts a third hydraulic cylinder 6. Through the cooperation of the two, the mold cavity height can be adjusted to meet different experimental requirements to ensure that the raw material molding space is adapted to the test requirements.

[0028] An opening and closing drive structure 4 is also provided on the support frame, which is used to drive and adjust the expansion and gathering and closing of the side template 1: when the opening and closing drive structure 4 drives the side template 1 to expand, and the second lifting drive structure lowers the lower template 3 to the lowest position, the side template 1 is in a horizontal state and is at the same height as the lower template 3. This state is convenient for removing the product after the experiment and cleaning and maintenance of the device; and when the opening and closing drive structure 4 drives the side template 1 to close, and cooperates with the upper template 2 and the lower template 3 respectively, the side template 1, the upper template 2 and the lower template 3 can form a sealed mold cavity, providing a closed space for wet pressing of raw materials, preventing leakage of raw materials, and ensuring the accuracy of the experiment.

[0029] Horizontal pressure rollers 7 are arranged on both sides of the upper template 2, and each horizontal pressure roller 7 is provided with a position adjustment component 8 and a liquid spray pipe component 9: the position adjustment component 8 can adjust the position of the horizontal pressure roller 7. When the mold cavity is sealed, the horizontal pressure roller 7 can be driven to achieve limited pressure on the upper template 2, further enhancing the sealing of the mold cavity, and avoiding leakage of raw materials or product molding defects caused by displacement of the upper template during the pressing process; the liquid spray pipe component 9 can flush the side template 1, upper template 2 and lower template 3 and spray the release agent. The flushing function can clean the raw materials remaining on the surface of the template before and after the experiment to ensure the cleanliness of the template. The spraying of the release agent can reduce the adhesion between the cement product and the template, facilitate the smooth demoulding of the product, and improve the experimental efficiency.

[0030] See the instructions attached Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the side formwork 1 is provided with four, and the opening and closing drive structure 4 includes four corner brackets 401 distributed in a rectangular array. The outer wall of the side formwork 1 is fixed with a main rotating rod 403 by bolts, and the lower end of the main rotating rod 403 is fixedly connected to a pry bar 406, and the lower end of the pry bar 406 is inclined toward the outside. The end of the lower part of the main rotating rod 403 close to the pry bar 406 is rotatably set on the corner bracket 401 through a support shaft 405. A lifting frame 402 is sleeved on the outer side of the side formwork 1, and a first hydraulic cylinder 410 is provided on both sides of the lifting frame 402. The push rod head end of the first hydraulic cylinder 410 is fixedly connected to the lifting frame 402 through a connecting block 411. When the push rod of the first hydraulic cylinder 410 reaches the maximum stroke, the side formworks 1 gather together and close. When the push rod of the first hydraulic cylinder 410 reaches the minimum stroke, the lifting frame 402 realizes the rotation and expansion of the opposite side formwork 1 around the support shaft 405 through the pry bar 406. The output end of the digital display control panel 10 is electrically connected to the input end of the first hydraulic cylinder 410. The upper outer side of the main rotating rod 403 is protruded with a first wedge-shaped protrusion 409, and the upper inner side of the lifting frame 402 is provided with an upper pressure notch 408 that abuts against the first wedge-shaped protrusion 409. When the first hydraulic cylinder 410 drives the lifting frame 402 to move upward until the upper pressure notch 408 abuts against the first wedge-shaped protrusion 409, the side template 1 can be gathered and fitted in the horizontal direction, and the lower inner side of the lifting frame 402 is provided with a lower introduction notch 407 that abuts against the pry bar 406. Through the above-mentioned specific structural design, when closed, the first wedge-shaped protrusion 409 cooperates with the upper pressure notch 408 to ensure that the side template fits tightly in the horizontal direction, thereby improving the sealing of the mold cavity and preventing leakage of raw materials; when unfolded, with the help of the pry bar 406 and the linkage of the lower introduction notch 407, the side template is horizontal and at the same height as the lower template that has dropped to the lowest position, which is convenient for removing the product and cleaning the device after the experiment; thus, the function of the opening and closing drive structure 4 is to realize the automatic unfolding and gathering and closing of the side template 1, thereby facilitating the rapid assembly and disassembly of the experimental mold.

[0031] See the instructions attached Figure 2 and Figure 3As shown, the first lifting drive structure adopts a lifting drive assembly 5, which includes a second hydraulic cylinder 501. The second hydraulic cylinder 501 is fixedly mounted on the support frame 15. The push rod head of the second hydraulic cylinder 501 faces downward and is fixedly connected to the upper side of the upper template 2. Two guide rods 502 are symmetrically distributed around the second hydraulic cylinder 501. The lower ends of the two guide rods 502 are fixedly connected to the upper side of the upper template 2. The upper ends of the two guide rods 502 are slidably connected to the guide slide holes provided at corresponding positions on the support frame 15. The output end of the digital display control panel 10 is electrically connected to the input end of the second hydraulic cylinder 501. The digital display control panel 10 outputs a control signal to the second hydraulic cylinder 501, which directly drives the upper template 2 to move up and down by driving the extension and contraction of its push rod, thereby adjusting the height of the upper template 2 to adapt to the mold cavity height under different experimental requirements. During the movement of the upper template 2, the guide rods 502 on both sides slide synchronously along the guide slide holes of the support frame 15, limiting the horizontal deviation of the upper template 2, ensuring that it moves smoothly only in the vertical direction, avoiding tilting or dislocation due to uneven force, and ensuring the sealing of the mold cavity when it is closed. While cooperating to achieve automatic and rapid assembly of the mold, it can also cooperate with the adjustment of the upper and lower height positions of the horizontal pressure roller 7, so that the height position of the horizontal pressure roller 7 is consistent with that of the upper template 2 and the lower template 3.

[0032] See the instructions attached Figure 8As shown, the position adjustment component 8 is used to accurately control the position of the horizontal pressure roller 7. The position adjustment component 8 includes a first electric telescopic rod 801, which is fixedly arranged on the support frame 15 through a fixed seat 802. The push rod head end of the first electric telescopic rod 801 faces upward and is fixedly connected to a lifting seat 804 used as an intermediate bearing structure. A second electric telescopic rod 803 is fixedly arranged on the lifting seat 804 to provide a horizontal driving force to adjust the lateral position of the horizontal pressure roller. The push rod head end of the second electric telescopic rod 803 is fixedly connected to the horizontal pressure roller 7, and the output end of the digital display control panel 10 is electrically connected to the input end of the first electric telescopic rod 801 and the second electric telescopic rod 803 respectively. In practice, the system features vertical position adjustment: the digital display control panel 10 controls the extension and retraction of the first electric telescopic rod 801, driving the vertical movement of the lifting platform 804, the second electric telescopic rod 803 above it, and the horizontal pressure roller 7. This allows for vertical adjustment of the horizontal pressure roller, ensuring proper positioning of the upper mold plate 2 and maintaining consistent distance between the upper and lower mold plates 2 and 3. Horizontal position adjustment: the digital display control panel 10 controls the extension and retraction of the second electric telescopic rod 803, directly driving the horizontal pressure roller 7 horizontally, moving it closer to or further away from the upper mold plate 2. This is used for position control of the upper mold plate 2 and for spray cleaning. Furthermore, it provides position control and pressure during mold cavity sealing: once the side mold plate 1, upper mold plate 2, and lower mold plate 3 form a sealed mold cavity, the first electric telescopic rod 801 adjusts the height of the horizontal pressure roller 7. The second electric telescopic rod 803 then drives the horizontal pressure roller 7 laterally, pressing it against the upper mold plate 2. This provides position control and pressure control of the upper mold plate, enhancing the mold cavity seal and preventing material leakage due to upper mold plate displacement during the pressing process.

[0033] See the instructions attached Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 12As shown, the liquid spraying pipe assembly 9 can realize the functions of template flushing and mold release agent spraying. The liquid spraying pipe assembly 9 includes a booster pump 901 arranged on the support frame 15. The liquid inlet of the booster pump 901 is connected to one end of the liquid inlet pipe 903. The other end of the liquid inlet pipe 903 is respectively connected to two branch liquid inlet pipes, and an electromagnetic three-way valve is provided between the three. One branch liquid inlet pipe is connected to an external cleaning liquid supply device, and the other branch liquid inlet pipe is connected to an external mold release agent supply device. The liquid outlet of the booster pump 901 is connected to one end of the liquid outlet pipe 902. The other end of the liquid outlet pipe 902 is connected to the horizontal pressure roller 7 through a spring liquid guide pipe 904. A liquid spraying channel is formed in the horizontal pressing roller 7, and a first spraying hole groove 906 for tilting toward the upper template 2, a second spraying hole groove 907 for tilting toward the lower template 3, and a third spraying hole groove 908 for vertically facing the lower template 3 are respectively formed on the outer side wall of the horizontal pressing roller 7. The lengths of the first spraying hole groove 906 and the third spraying hole groove 908 along the axial direction of the horizontal pressing roller 7 are consistent with each other, and are consistent with the length of the upper template 2 along the axial direction of the horizontal pressing roller 7. The length of the second spraying hole groove 907 along the axial direction of the horizontal pressing roller 7 is consistent with the distance between the outermost edges of the two side templates 1 in the unfolded state. A rotating device is provided in the liquid spraying channel. Rod 910 is provided with a sealing rotary block 911 having a fan-shaped cross-section. A motor 909 is provided at the end of horizontal pressure roller 7 for driving rotary rod 910. When motor 909 drives rotary rod 910 and sealing rotary block 911 to rotate, sealing rotary block 911 can simultaneously close first spray hole slot 906, second spray hole slot 907, and third spray hole slot 908, open only third spray hole slot 908, and close only third spray hole slot 908. The output of digital display control panel 10 is electrically connected to the input of motor 909. In actual application, the electromagnetic three-way valve can switch the two branch liquid inlet pipes on and off, such as connecting cleaning liquid and release agent respectively. The liquid enters booster pump 901 through liquid inlet pipe 903 and, after being pressurized, is delivered to the liquid spray channel of horizontal pressure roller 7 through liquid outlet pipe 902 and spring liquid guide pipe 904. The spring liquid guide tube 904 can flexibly deform with the position adjustment of the horizontal pressure roller 7 to ensure continuous liquid delivery. Through three different directions of spraying holes and state switching, residual raw materials on the upper template 2, lower template 3, and side template 1 can be specifically washed or release agents can be sprayed.

[0034] The injection pipe structure 12 includes a second injection pipe joint 1204 arranged on the support frame 15. The second injection pipe joint 1204 is fixed on the support frame 15 through a fixing plate 1203. A first injection pipe joint 1201 is arranged on the upper template 2. A telescopic tube 1202 is arranged between the first injection pipe joint 1201 and the second injection pipe joint 1204.

[0035] A waste liquid collection box 11 and a cover 14 are provided on the outside of the support frame 15 from bottom to top. A drain pipe 1101 is connected to one side of the bottom of the waste liquid collection box 11. An observation port 1401 is provided on the cover 14, and an opening and closing door 1402 is provided at the observation port 1401.

[0036] Working principle and technical effects of the present invention: When in use, confirm that the supporting frame 15 is stable, the digital display control panel 10 is powered normally, and the various drive structures, such as the opening and closing drive structure 4, the lifting drive component 5, the third hydraulic cylinder 6, the position adjustment component 8, etc. are connected correctly.

[0037] The first hydraulic cylinder 410 is controlled by the digital display control panel 10 to move the lifting frame 402 down to the minimum stroke, driving the side template 1 to rotate and unfold around the support shaft 405. At this time, the side template 1 is in a horizontal state; at the same time, the third hydraulic cylinder 6 is controlled to drive the lower template 3 to descend to the lowest position, ensuring that the upper surface of the side template 1 is at the same height as the upper surface of the lower template 3.

[0038] Template cleaning and release agent spraying, control the position adjustment component 8, adjust the height of the lifting platform 804 through the first electric telescopic rod 801, and cooperate with the second electric telescopic rod 803 to drive the horizontal pressure roller 7 to move to the template to be processed area.

[0039] Start the liquid spraying pipeline assembly 9, control the electromagnetic three-way valve to switch to the release agent branch inlet pipe through the digital display control panel 10, and the booster pump 901 transports the release agent to the spray channel of the horizontal pressure roller 7 through the inlet pipe 903, the outlet pipe 902, and the spring liquid guide pipe 904; control the motor 909 to drive the rotating rod 910 and the sealing rotating block 911 to spray the release agent on the side template 1, the upper template 2, and the lower template 3. Specifically, first switch to the state where only the third spray hole slot 908 is open, and spray the outermost side template 1, and then switch to the state where only the third spray hole slot 908 is closed, and the first spray hole slot 906 and the third spray hole slot 908 respectively realize the spraying of the upper template 2 and the spraying of the lower side template 1 and the lower template 3. If the template needs to be cleaned, switch the electromagnetic three-way valve to the cleaning liquid branch inlet pipe, repeat the above-mentioned liquid spraying operation, and the waste liquid is collected by the waste liquid collection box 11 and finally discharged through the drain pipe 1101.

[0040] The push rod of the first hydraulic cylinder 410 is driven to extend to the maximum stroke through the digital display control panel 10, and the lifting frame 402 moves upward. The upper pressure notch 408 thereof abuts against the first wedge-shaped protrusion 409 of the main rotating rod 403, forcing the side template 1 to gather and close; the pressure edge 201 of the upper template 2 forms a limit for the side template 1, ensuring that the side template 1 fits with the upper template 2 and the lower template 3 to form a sealed mold cavity.

[0041] The first and second electrically operated telescopic rods 801 and 803 of the position adjustment assembly 8 drive the horizontal pressure roller 7 against the upper mold plate 2, enhancing the mold cavity's sealing. Raw material is injected through the injection pipe structure 12. An external feeder is connected to the second injection pipe connector 1204. The raw material enters the mold cavity through the telescopic pipe 1202 and the first injection pipe connector 1201. The telescopic pipe 1202 can adapt to changes in the height of the upper mold plate 2.
