Description

Technical Field

[0001] This invention relates to the field of ceramic hydraulic machinery technology, and in particular to a multi-cavity brick press. Background Technology

[0002] Figure 18 The oil tank 14 is a brick press placed on both sides of the upper beam 11'. The oil tank 14 is assembled and sealed by an oil chamber 21' and a tank cover 141. The oil tank 14 contains hydraulic oil. During operation, the hydraulic oil enters the piston chamber 33' of the fixed seat 31' to drive the piston to perform the pressing operation. During pressing, the hydraulic oil exerts a downward force on the piston 32', thus generating an upward reaction force. The reaction force acts on the lower plane of the fixed seat 31'. Since the fixed seat 31' is located at the central axis of the upper beam 11', the reaction force is mainly concentrated at the central axis of the lower plane of the upper beam 11'. Therefore, under this stress condition, in order to ensure the structural strength of the upper beam 11', the ribs in the middle of the upper beam 11' usually need to be made very thick. However, this design makes the upper beam 11' very heavy.

[0003] Figure 19 In another type of multi-frame brick press, the oil tank 14 is placed above the upper beam 11'. During operation, the reaction force of the hydraulic oil still acts upward on the lower plane of the fixed seat 31'. Since the filling valve is located at the central axis of the fixed seat 31', but there is no structural support above the central axis of the fixed seat 31', the stress situation at the central axis of the fixed seat 31' is still not ideal. Under this stress condition, in order to ensure the structural strength of the fixed seat 31', the thickness of the upper plane of the fixed seat 31' needs to be increased, which will make the fixed seat very heavy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-cavity brick press that can improve the strength of the upper beam, reduce the weight of the upper beam and the fixed base, and save materials; in addition, it can also save oil tanks and oil tank covers, and improve the overall aesthetics.

[0005] To solve the above-mentioned technical problems, the present invention provides a multi-cavity brick press, including a frame and a brick pressing mechanism. The frame includes an upper beam and a lower beam, and the brick pressing mechanism includes a fixed seat, a piston and a moving beam. The fixed seat is connected to the lower part of the upper beam, the piston is connected to the moving beam, the moving beam can move up and down within the fixed seat, and the moving beam and the fixed seat can form a closed piston cavity.

[0006] The frame also includes an oil storage section located inside the upper beam. The oil storage section includes multiple oil chambers distributed within the upper beam. Ribs are provided between the multiple oil chambers and support the upper and lower ends of the upper beam. The upper beam also includes an outer support that can seal the multiple oil chambers within the upper beam.

[0007] The oil storage section also includes a filling port, which is located at the bottom of the oil chamber. Multiple oil chambers can communicate with the filling port, and oil can enter the brick pressing mechanism from the filling port.

[0008] As an improvement to the above solution, the brick pressing mechanism further includes a filling chamber and a filling valve. The filling chamber is located at the bottom of the upper beam and communicates with the filling port. The filling valve is located in the filling chamber and connected between the filling chamber and the piston chamber. Oil can pass through the filling valve from the filling port and enter the piston chamber.

[0009] As an improvement to the above scheme, the number of oil cavities is 2n, where n≥2. The 2n oil cavities are evenly distributed on the side of the upper beam. The side of each oil cavity is provided with front and rear stiffening plates and left and right stiffening plates. The front and rear stiffening plates, the left and right stiffening plates and the outer support can form the oil cavity. The bottom of the oil cavities are interconnected and converge in the filling port.

[0010] As an improvement to the above scheme, the number of filling ports is n-1, where n≥2, and the filling ports are located below the oil cavity and at the intersection of the front and rear stiffening plates and the left and right stiffening plates.

[0011] As an improvement to the above solution, the outer support is provided with an inspection hole, which is either racetrack-shaped or circular.

[0012] As an improvement to the above scheme, the number of filling ports is n or 2n-2, where n≥2. The filling ports are located between two adjacent oil chambers, and the filling ports are located on the left and right stiffening plates or the front and rear stiffening plates.

[0013] As an improvement to the above scheme, the number of filling ports is equal to the number of oil chambers, and each filling port is located below each oil chamber.

[0014] As an improvement to the above solution, there is one filling valve and one filling chamber, and the bottoms of the multiple filling ports converge in the filling chamber.

[0015] As an improvement to the above solution, there are multiple filling valves and multiple filling chambers, with the multiple filling valves distributed on the front and rear sides or left and right sides of the oil chamber.

[0016] As an improvement to the above solution, the frame further includes a steel wire layer wound around the frame.

[0017] Implementing this invention has the following beneficial effects:

[0018] This invention relates to a multi-cavity brick press machine, which includes a frame and a brick pressing mechanism. The frame comprises an upper beam and a lower beam, and the brick pressing mechanism includes a fixed seat, a piston, and a moving beam. The frame also includes an oil storage section containing multiple oil cavities located inside the upper beam. In contrast to traditional brick press machines, where the oil storage section is mounted on the outside of the upper beam, this invention's oil storage section is located inside the upper beam and integrally formed with it. Ribs are provided between the multiple oil cavities, and these ribs stand inside the upper beam, with their ends supporting the upper and lower ends of the upper beam, respectively. Therefore, the ribs not only separate the oil cavities but also support the upper beam and improve its structural strength. This design is particularly suitable for brick presses with a longer width, where the stress distribution at the center of the oil cavity is better, and the thickness of the upper surface of the oil cavity is significantly reduced. Furthermore, due to the effect of the stiffening ribs, the strength of the upper beam is increased, thus allowing for a reduction in the thickness of both the upper beam and the fixed base, thereby reducing their weight and saving materials. Additionally, since the oil cavity is located within the upper beam and sealed by its outer support, sealing components such as a tank lid can be omitted, saving materials and improving the overall aesthetics of the equipment.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this document are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0039] Referring to Figure 1, this embodiment of the invention discloses a multi-cavity brick press, including a frame 1 and a brick pressing mechanism 3. The frame 1 includes an upper beam 11 and a lower beam 12, with the upper beam 11 located at the top and the lower beam 12 located at the bottom. The brick pressing mechanism 3 includes a fixed seat 31, a piston 32, and a moving beam 34. The fixed seat 31 is connected to the lower part of the upper beam 11 and is part of the piston 32 cylinder. The piston 32 is connected to the moving beam 34, which can move up and down within the fixed seat 31. The moving beam 34 and the fixed seat 31 can form a sealed piston cavity 33, into which hydraulic oil can enter and drive the moving beam 34 to move up and down within the fixed seat 31 via the piston 32, thereby enabling the pressing of ceramic tiles.

[0040] The oil storage section 2 is located inside the upper beam 11 and can store hydraulic oil. To achieve oil storage, the oil storage section 2 includes multiple oil chambers 21 distributed within the upper beam 11. Hydraulic oil can be stored in the oil chambers 21. In traditional brick presses, the oil storage section 2 is assembled outside the upper beam 11. However, compared to traditional brick presses, in this embodiment of the invention, the oil storage section 2 is located inside the upper beam 11 and is integrally formed with the upper beam 11. Ribs 22 are provided between the multiple oil chambers 21. The stiffening ribs 22 separate the various oil cavities 21 and support the upper beam 11 at both ends. The stiffening ribs 22 act as reinforcing ribs of the upper beam 11, thereby improving the overall structural strength of the upper beam 11. The upper beam 11 also includes an outer support 23, which seals the multiple oil cavities 21 within the upper beam 11. The outer support 23 acts as an external enclosure structure for the oil cavities 21 and provides external support for the upper beam 11. The combination of the outer support 23 and the stiffening ribs 22 significantly improves the strength of the upper beam 11. Furthermore, since the oil cavities 21 occupy part of the space of the upper beam 11, they effectively reduce the weight of the upper beam 11, achieving both material reduction and increased structural strength. Since the fixing seat 31 is fixed to the bottom of the upper beam 11, the reaction force of the hydraulic oil will act on the fixing seat 31 and the upper beam 11 during pressing. Due to the reinforcement of the upper beam 11 structure by the stiffening plate 22 and the outer support 23, the thickness of the fixing seat 31 can also be reduced, thereby saving materials and reducing weight. Compared with brick presses with oil tanks placed at the front and rear, this invention can eliminate the need for sealing parts such as tank lids, thereby further saving materials and reducing weight, and also improving the overall aesthetics.

[0041] In order to connect the brick pressing mechanism 3, the oil storage part 2 also includes a filling port 24. The filling port 24 is located at the bottom of the oil chamber 21. Multiple oil chambers 21 can be connected to the filling port 24. Oil can enter the brick pressing mechanism 3 from the filling port 24, specifically into the piston chamber 33, and drive the moving beam 34 in the fixed seat 31 to perform brick pressing operation through the piston 32. After the brick pressing is completed, the hydraulic oil can also return from the piston chamber 33 to the oil chamber 21 through the filling port 24.

[0042] The multi-cavity brick press of the present invention includes a frame 1 and a brick pressing mechanism 3. The frame 1 includes an upper beam 11 and a lower beam 12. The brick pressing mechanism 3 includes a fixed seat 31, a piston 32, and a moving beam 34. The frame 1 also includes an oil storage section 2, which includes multiple oil cavities 21 located inside the upper beam 11. Rib plates 22 are provided between the multiple oil cavities 21 and stand inside the upper beam 11. The two ends of the rib plates 22 are respectively supported by the upper and lower ends of the upper beam 11. Therefore, the rib plates 22 not only separate the oil cavities 21 but also support the upper beam 11 and improve its structural strength. The oil cavities 21 make full use of the overall layout of the upper beam 11, and are especially suitable for brick presses that are wide from left to right (with a large distance between the left and right columns). In this case, the stress distribution at the center of the oil cavity 21 is better, and the thickness of the upper surface of the oil cavity 21 is greatly reduced. Furthermore, due to the effect of the stiffening rib 22, the strength of the upper beam 11 is increased. Therefore, the thickness of both the upper beam 11 and the fixing seat 31 can be reduced, thereby reducing their weight and achieving the effect of saving materials and installation procedures. In addition, since the oil cavity 21 is located inside the upper beam 11 and sealed by the outer support 23 of the upper beam 11, sealing components such as tank lids can be omitted, saving materials and improving the overall aesthetics of the equipment.

[0043] It should be noted that the frame 1 also includes a steel wire layer 13, which is wound around the frame 1. The steel wire layer 13 wound around the frame 1 further improves the structural stability of the upper beam 11 and the lower beam 12. The steel wire layer 13 can be wound in a single winding or multiple winding manner.

[0044] To control the hydraulic oil, the brick pressing mechanism 3 further includes a filling chamber 35 and a filling valve 36. The filling chamber 35 is located at the bottom of the upper beam 11 and communicates with the filling port 24. The filling valve 36 is located in the filling chamber 35 and connects the filling chamber 35 to the piston chamber 33. The filling valve 36 controls the entry and exit of the hydraulic oil. The hydraulic oil can pass through the filling port 24, the filling valve 36, and enter the piston chamber 33, or it can pass through the filling valve 36, enter the filling port 24, and return to the oil chamber 21. The number of filling chambers 35 corresponds to the number of filling valves 36, but not necessarily to the number of filling ports 24. The filling ports 24 can collect hydraulic oil from the oil chamber 21 and then flow back to the filling chambers 35 and the filling valves 36.

[0045] In this embodiment of the invention, the number of oil cavities 21 is multiple, and the number of oil cavities 21 can be determined according to the cross-sectional width of the brick press. Preferably, the number of oil cavities 21 is 2n, where n≥2. The 2n oil cavities 21 are evenly distributed on the side of the upper beam 11, with n oil cavities 21 distributed on the front side of the upper beam 11 and the other n oil cavities 21 distributed on the rear side of the upper beam 11, thereby achieving an even distribution and further improving the uniform force distribution of the stiffening plate 22. The stiffening plate 22 includes front and rear stiffening plates 221 and left and right stiffening plates 222. The front and rear stiffening plates 221 span the front and rear sides of the upper beam 11, and the left and right stiffening plates 222 span the left and right sides of the upper beam 11. The sides of the oil cavity 21 are respectively provided with front and rear stiffening plates 221 and left and right stiffening plates 222. The front and rear stiffening plates 221, the left and right stiffening plates 222 and the outer support 23 can surround the oil cavity 21. The bottoms of the oil cavities 21 are interconnected and converge in the filling port 24. The number of filling ports 24 is (n-1), where n≥2. The filling ports 24 are located below the oil cavity 21 and at the intersection of the front and rear stiffening plates 221 and the left and right stiffening plates 222. The bottom of the oil cavity 21 has interconnected openings, through which the hydraulic oil in the oil cavity 21 can mix with each other. The filling port 24 is located below the openings and can receive the mixed hydraulic oil from each of the oil cavities 21. Since the filling port 24 is surrounded by the front and rear stiffening plates 221 and the left and right stiffening plates 222, the opening of the filling port 24 not only does not affect the structural strength of the front and rear stiffening plates 221 and the left and right stiffening plates 222, but also further improves the structural strength of the upper beam 11. The outer support 23 is provided with an inspection hole 223, which is racetrack-shaped or circular. The inspection hole 223 can be used to observe the oil cavity 21 and to inspect the interior of the upper beam 11.

[0046] See Figure 1- Figure 4 In the first embodiment of the present invention, there are four oil cavities 21, where n=2. Two of the oil cavities 21 are located on the front side of the upper beam 11, and the other two are located on the rear side of the upper beam 11. There is one filling port 24, located at the intersection of the front and rear stiffening plates 221 and the left and right stiffening plates 222 below the oil cavities 21. Preferably, the filling port 24 is located at the central axis of the upper beam 11. The inspection hole 223 is racetrack-shaped.

[0047] See Figure 5 In the second embodiment of the present invention, the inspection hole 223 is circular in shape.

[0048] In other embodiments, the number of filling ports 24 can be n or 2n-2, where n≥2. The filling ports 24 are located between two adjacent oil cavities 21. The filling ports 24 are located on the left and right stiffening plates 222 or on the front and rear stiffening plates 221. When the filling ports 24 are located on the left and right stiffening plates 222, the number of filling ports 24 is n. The two oil cavities 21 located on the front and rear sides are separated by the left and right stiffening plates 222, and one of the filling ports 24 is located on the left and right stiffening plates 222. Since the number of oil cavities 21 is 2n, the number of filling ports 24 is n. When the filling port 24 is located on the front and rear stiffening plates 221, the number of filling ports 24 is 2n-2. The two oil chambers 21 located on the left and rear sides are separated by the front and rear stiffening plates 221, and one of the filling ports 24 is located on the front and rear stiffening plates 221, so the number of filling ports 24 is 2n-2. Providing the filling ports 24 in the left and right stiffening plates 222 or the front and rear stiffening plates 221 can strengthen the strength of the left and right stiffening plates 222 or the front and rear stiffening plates 221, thereby further improving the strength of the upper beam 11. At the same time, a single filling port 24 can correspond to fewer oil chambers 21, thus enabling more precise control of the hydraulic oil flow rate.

[0049] To further improve the control accuracy of hydraulic oil, the number of filling ports 24 can be equal to the number of oil chambers 21, with each filling port 24 located below each oil chamber 21, thereby enabling the hydraulic oil in a single oil chamber 21 to be controlled separately, achieving the purpose of precise control.

[0050] The number of filling valves 36 and filling ports 24 may be unequal, and the number of filling valves 36 and filling chambers 35 is one each. The bottoms of multiple filling ports 24 converge in the filling chamber 35, thereby enabling multiple streams of hydraulic oil to be uniformly collected into a single filling chamber 35, and the flow rate of the hydraulic oil is controlled by a single filling valve 36. In other embodiments, multiple filling valves 36 and filling chambers 35 may be provided, with the number of filling valves 36 and filling chambers 35 being equal, and the multiple filling valves 36 being distributed on the front and rear sides or left and right sides of the oil chamber 21.

[0051] See Figures 6-9 In the third embodiment of the present invention, there are four oil chambers 21, where n=2. Two of the oil chambers 21 are located on the front side of the upper beam 11, and the other two are located on the rear side of the upper beam 11. There are two filling ports 24, which are located at the intersection of the front and rear stiffening plates 221 and the left and right stiffening plates 222 below the oil chambers 21. There are two filling valves 36 and two filling chambers 35, with each filling chamber 35 corresponding to one filling port 24. This allows the filling valves 36 to separately control the hydraulic oil in the front and rear oil chambers 21, thereby improving the flow control accuracy.

[0052] See Figures 10-13 In the fourth embodiment of the present invention, the number of oil chambers 21 is 6, where n=3. Three oil chambers 21 are distributed on the front side of the upper beam 11, and the other three are distributed on the rear side of the upper beam 11. The number of filling ports 24 is 2. Since there are two intersections between the front and rear stiffening plates 221 and the left and right stiffening plates 222, the two filling ports 24 are respectively located at the two intersections of the front and rear stiffening plates 221 and the left and right stiffening plates 222 below the oil chambers 21. In the fourth embodiment, there are two filling valves 36 and two filling chambers 35, each corresponding to one filling port 24. This allows the filling valve 36 to separately control the hydraulic oil in the front and rear oil chambers 21, improving control accuracy. Alternatively, there can be three filling ports 24, each located on one of the left and right stiffening plates 222.

[0053] See Figures 14-17In the fifth embodiment of the present invention, there are six oil chambers 21, where n=3. Three of the oil chambers 21 are located on the front side of the upper beam 11, and the other three are located on the rear side of the upper beam 11. There are six filling ports 24, each corresponding to an oil chamber 21. In the fifth embodiment, there is one filling valve 36 and one filling chamber 35. One filling chamber 35 corresponds to six filling ports 24. The hydraulic oil in the oil chambers 21 is collected from their respective filling ports 24 and passes through the filling chambers 35 and the filling valve 36 to supply oil to the piston chamber 33.

[0054] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
