Description

Technical Field

[0001] This invention relates to the field of brick press technology, and in particular to a beam-column type brick press. Background Technology

[0002] A brick press is a large piece of equipment used to press brick blanks. The frame of a beam-column type brick press typically consists of an upper beam, a lower beam, and a cylindrical sleeve. This frame is usually connected by large nuts and large tie rods. The cylindrical sleeve connects the upper and lower beams, and the large tie rod passes through the upper beam, the cylindrical sleeve, and the lower beam sequentially from top to bottom. Both ends of the large tie rod are tightened with large nuts. Besides supporting the upper beam, the cylindrical sleeve's outer wall also guides the lifting and lowering of the moving beam. This type of brick press has the following problems in production and installation:

[0003] 1. Due to the large size of the brick press and the large size of the large nut, it is not possible to use a standard hydraulic wrench to pre-tighten the large nut when assembling the brick press frame. A special tensioner is required to stretch the large tie rod before the large nut can be pre-tightened. The size of the tensioner is often comparable to the size of the large nut and usually needs to be specially made. Moreover, a very large tensioner is required to pre-tighten the large tie rod. When the product is delivered to the customer, the huge tensioner must also be delivered to the site to complete the installation.

[0004] 2. Because the outer wall of the round tube sleeve is used to guide the moving beam, it requires precision machining and a series of processes such as chrome plating to ensure a smooth, durable, and corrosion-resistant surface. Furthermore, the round tube sleeve also serves as a supporting component, and its diameter (cross-sectional area) needs to match the tie rod. The larger the tonnage of the brick press, the larger the tie rod and the larger the diameter of the round tube sleeve, resulting in expensive processing costs. Moreover, the diameter of the guide sleeve for the moving beam also needs to match the diameter of the round tube sleeve; a larger round tube sleeve diameter requires a larger guide sleeve diameter, significantly increasing material costs. Additionally, the diameter of the round tube sleeve varies for different tonnage models, and the diameter of the guide sleeve also varies accordingly, which is detrimental to modular lean manufacturing.

[0005] In summary, current beam-column presses suffer from problems such as inconvenient frame installation and high manufacturing costs for round tube sleeves and tensioners. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a beam-column type brick press that facilitates the installation of the frame, significantly reduces the manufacturing cost of the sleeve, and has a wide range of applications.

[0007] To solve the above-mentioned technical problems, the present invention provides a beam-column type brick press, including an upper beam, a moving beam, a lower beam, a sleeve, and tie rods. The moving beam is movably connected below the upper beam. The sleeve is disposed between the upper beam and the lower beam and is sleeved over the tie rods. There are multiple tie rods, which are respectively fixed to the top side of the upper beam and the bottom of the lower beam by tightening components.

[0008] The beam-column type brick press also includes a guiding module, which comprises a guide sleeve and a guide rod. The guide rod is fixed to the side of the sleeve, and the guide sleeve is disposed on the side of the moving beam. The guide sleeve is sleeved over the guide rod and slidably connected to the guide rod. The moving beam can drive the guide sleeve to slide along the guide rod.

[0009] As an improvement to the above solution, the guide module further includes a guide seat and a mounting boss. The mounting boss protrudes from the side of the sleeve, and the guide seat is fixed to the sleeve by the mounting boss. The guide seat is located at the upper and lower ends of the guide rod.

[0010] As an improvement to the above solution, the sleeve is hollow and has a through hole. Multiple tie rods are disposed in the through hole. The upper beam and the lower beam are respectively provided with upper connecting parts and lower connecting parts on both sides. The positions of the upper connecting parts and the lower connecting parts correspond to the positions of the sleeve. The tie rods can pass through the upper connecting parts and the lower connecting parts.

[0011] As an improvement to the above solution, the upper connecting part and the lower connecting part are respectively provided with a plurality of upper fixing holes and lower fixing holes. Each of the pull rods corresponds to each of the upper fixing holes and the lower fixing holes. The pull rod passes upward through the upper fixing hole and is fixed with the tightening member. The pull rod passes downward through the lower fixing hole and is fixed with the tightening member.

[0012] As an improvement to the above solution, multiple tie rods are evenly distributed within the through hole.

[0013] As an improvement to the above solution, the beam-column type brick press also includes a pad plate, which is provided on the left and right sides of the top of the upper beam and the left and right sides of the bottom of the lower beam. The pad plate is provided with through holes, the number of which corresponds to the number of tie rods. The tie rods can pass through the pad plate and connect to the upper beam and the lower beam.

[0014] As an improvement to the above solution, the upper connecting part and the lower connecting part are hollow, and the upper connecting part and the lower connecting part are respectively provided with an upper receiving hole and a lower receiving hole. Multiple pull rods pass through the through hole, the upper receiving hole, the through hole and the lower receiving hole in sequence from top to bottom.

[0015] As an improvement to the above solution, the through hole is divided into multiple regions, each region is separated by a partition plate, and the multiple tie rods are evenly distributed in each region.

[0016] Implementing this invention has the following beneficial effects:

[0017] This invention relates to a beam-column type brick press machine, which includes a sleeve, tie rods, and a guide module. The sleeve is located between the upper beam and the lower beam, and is fitted over the tie rods. The tie rods are fixed to the top side of the upper beam and the bottom of the lower beam respectively by tightening components. There are multiple tie rods, which can fix the upper beam, the sleeve, and the lower beam together. In traditional brick press machines, the number of tie rods corresponds to the number of sleeves, so the diameter of the sleeve is directly related to the diameter of the tie rod. However, in this invention, multiple tie rods are provided in one sleeve, and the diameter of the tie rods can be set to be smaller. Therefore, the tightening components can be of smaller specifications. Correspondingly, there is no need to use a tensioner to stretch the tie rods. A conventional hydraulic wrench can be used to pre-tighten the tightening components, thus facilitating the installation of the frame.

[0018] Furthermore, in traditional brick presses, the sleeve serves both to support the upper beam and guide the movement of the moving beam. However, in this invention, the sleeve only provides support; its guiding function is handled by the guiding module. The guiding module includes a guide sleeve and a guide rod. The guide rod is fixed to the side of the sleeve, and the guide sleeve is located on the side of the moving beam. The moving beam can drive the guide sleeve to slide along the guide rod. Therefore, the design of the sleeve only needs to consider structural strength, eliminating the need for chrome plating or other processes on the large outer wall of the sleeve. Moreover, the cross-sectional area of ​​the sleeve is no longer related to the cross-sectional area of ​​the guiding structure. The guide rod and guide sleeve can be designed solely based on guiding requirements, significantly reducing material costs. Attached Figure Description

[0030] 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 text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0031] See Figure 1 This invention discloses a beam-column type brick press, including an upper beam 1, a moving beam 7, a lower beam 2, a sleeve 3, and tie rods 4. The upper beam 1, the lower beam 2, and the sleeve 3 constitute the frame of the beam-column type brick press. The moving beam 7 is movably connected below the upper beam 1 and can be raised and lowered to press the brick blanks. In this invention, the sleeve 3 is located between the upper beam 1 and the lower beam 2, and is sleeved over the tie rods 4. Multiple tie rods 4 are used, and are respectively fixed to the top side of the upper beam 1 and the bottom of the lower beam 2 by tightening elements 8. The tightening elements 8 can be nuts. The sleeve 3 can accommodate multiple tie rods 4, and the diameter of the tie rods 4 can be reduced. The multiple tie rods 4 serve to fix the frame, such as... Figures 9-11As shown, in traditional brick presses, sleeves 3' correspond one-to-one with pull rods 4', and the diameter of pull rods 4' directly corresponds to that of sleeves 3'. Larger brick presses have larger diameters of pull rods 4' and sleeves 3', resulting in higher processing costs. Moreover, the corresponding tightening parts 8' are also larger, requiring a special tensioner to stretch the pull rods 4' to pre-tighten the tightening parts 8'. In this invention, multiple small pull rods 4' are used instead of the traditional single large pull rod 4'. This not only facilitates the processing of the pull rods 4' but also reduces the size of the corresponding tightening parts 8, allowing the tightening parts 8 to be pre-tightened using a general hydraulic wrench. This facilitates the installation of the frame and eliminates the need to transport the tensioner, reducing transportation costs.

[0032] In addition, the beam-column type brick press also includes a guide module 5, which includes a guide sleeve 51 and a guide rod 52. The guide rod 52 is fixed to the side of the sleeve 3, and the guide sleeve 51 is located on the side of the moving beam 7. The guide sleeve 51 is sleeved on the outside of the guide rod 52 and slidably connected to the guide rod 52. The guide rod 52 is vertically arranged, and the moving beam 7 can drive the guide sleeve 51 to slide along the guide rod 52. In traditional brick presses, the moving beam 7' is connected to the sleeve 3'. In addition to providing connection and support for the upper beam 1' and the lower beam 2', the sleeve 3' also provides lifting and guiding for the moving beam 7'. Therefore, the traditional sleeve 3' must meet both the strength requirements of support and the requirements of a smooth and durable surface. To meet the high strength requirements, the traditional sleeve 3' needs a larger diameter, but a larger diameter sleeve 3' is not easy to process, and its surface treatment cost is also expensive. In this invention, the guide module 5 replaces the sleeve 3 to perform the guiding function, and the guide rod 52 can be a long rod with a smaller diameter, making it easier to process the surface of the guide rod 52, and the material cost and processing cost are both lower.

[0033] The beneficial effects of the embodiments of the present invention are as follows:

[0034] In this embodiment of the invention, the beam-column type brick press machine is provided with a sleeve 3, a tie rod 4, and a guide module 5. The sleeve 3 is located between the upper beam 1 and the lower beam 2, and is sleeved over the tie rod 4. The tie rod 4 is fixed to the top side of the upper beam 1 and the bottom of the lower beam 2 respectively by a tightening member 8. There are multiple tie rods 4, which can fix the upper beam 1, the sleeve 3, and the lower beam 2 together. In traditional brick press machines, the number of tie rods 4' corresponds to the number of sleeves 3', so the diameter of the sleeves 3' is directly related to the diameter of the tie rods 4'. However, in this invention, multiple tie rods 4 are provided in one sleeve 3, and the diameter of the tie rod 4 can be set to be smaller. Therefore, the tightening member 8 can be of a smaller specification. Correspondingly, there is no need to use a tensioner to stretch the tie rod 4. The tightening member 8 can be pre-tightened using a conventional hydraulic wrench, thereby facilitating the installation of the frame. Furthermore, in traditional brick presses, the sleeve 3' serves both to support the upper beam 1' and guide the lifting and lowering of the moving beam 7'. However, in this invention, the sleeve 3 only provides support; its guiding function is undertaken by the guiding module 5. The guiding module 5 includes a guide sleeve 51 and a guide rod 52. The guide rod 52 is fixed to the side of the sleeve 3, and the guide sleeve 51 is located on the side of the moving beam 7. The moving beam 7 can drive the guide sleeve 51 to slide along the guide rod 52. Therefore, the design of the sleeve 3 only needs to consider structural strength, eliminating the need for chrome plating or other processes on the large outer wall of the sleeve 3. Moreover, the cross-sectional area of ​​the sleeve 3 is no longer related to the cross-sectional area of ​​the guiding structure. The guide rod 52 and guide sleeve 51 can be designed solely based on guiding requirements, significantly reducing material costs.

[0035] Specifically, the guide module 5 further includes a guide seat 53 and a mounting boss 54. The mounting boss 54 protrudes from the side of the sleeve 3. The guide seat 53 is fixed to the sleeve 3 by the mounting boss 54. The guide seat 53 is located at both the upper and lower ends of the guide rod 52 and is used to fix the guide rod 52 from both ends. The guide module 5 can be adapted to several brick presses of similar tonnage without changing the diameter of the guide rod 52 and the guide sleeve 51 or the position of the guide seat 53 due to different tonnages, thus enabling modular production and management.

[0036] See Figures 1-4The present invention discloses a first embodiment. In the first embodiment, the sleeve 3 is hollow and has a through hole 31. Multiple pull rods 4 are disposed in the through hole 31. The diameter of the pull rods 4 can be determined according to the preload requirement and the number of pull rods 4 that the sleeve 3 can accommodate. The upper beam 1 and the lower beam 2 are respectively provided with an upper connecting part 11 and a lower connecting part 21 on both sides. The positions of the upper connecting part 11 and the lower connecting part 21 correspond to the positions of the sleeve 3. The pull rods 4 can pass through the upper connecting part 11 and the lower connecting part 21. After passing through the upper connecting part 11 and the lower connecting part 21, the upper beam 1, the sleeve 3 and the lower beam 2 can be connected together using the tightening member 8. To improve the fixing effect, the upper connecting part 11 and the lower connecting part 21 are respectively provided with multiple upper fixing holes 111 and lower fixing holes 211. Each tie rod 4 corresponds to each of the upper fixing holes 111 and lower fixing holes 211, and each tie rod 4 can pass through each of the upper fixing holes 111 and lower fixing holes 211. The upper fixing holes 111 and lower fixing holes 211 provide a limit for the tie rod 4, ensuring the fixing effect. The tie rod 4 passes upward through the upper fixing hole 111 and is fixed with the tightening member 8, and the tie rod 4 passes downward through the lower fixing hole 211 and is fixed with the tightening member 8. In the first embodiment, the tightening member 8 directly contacts and tightens the upper beam 1. Multiple tie rods 4 are evenly distributed in the through hole 31, and multiple tie rods 4 can be evenly stressed, ensuring that each tie rod 4 can exert good mechanical performance.

[0037] See Figure 5 and Figure 6The present invention discloses a second embodiment. In the second embodiment, the tightening member 8 does not directly contact the upper beam 1. The beam-column type brick press also includes a pad 6. The pad 6 is provided on the left and right sides of the top of the upper beam 1 and the left and right sides of the bottom of the lower beam 2. The tightening member 8 is fixed on the pad 6. In order to limit the position of the tightening member 8, the pad 6 is provided with through holes 61. The number of through holes 61 corresponds to the number of pull rods 4. The pull rods 4 can pass through the pad 6 and connect to the left and right sides of the upper beam 1 and the left and right sides of the lower beam 2, thereby fixing the upper beam 1 and the lower beam 2. The tightening member 8 can apply a fixing effect to the upper beam 1 and the lower beam 2 through the pad 6. By adding the pad 6, the upper beam 1 and the lower beam 2 can avoid machining the upper fixing hole 111 and the lower fixing hole 211. Since the upper beam 1 and the lower beam 2 are large in volume and thickness, the upper fixing hole 111 and the lower fixing hole 211 are numerous and small in size, making machining difficult. However, with the pad 6, only the through hole 61 for limiting the pull rod 4 needs to be machined on the pad 6. The pad 6 is small in volume and thickness, making machining convenient. The upper connecting part 11 and the lower connecting part 21 can be hollow. The upper connecting part 11 and the lower connecting part 21 are respectively provided with an upper receiving hole 112 and a lower receiving hole 212. Multiple pull rods 4 pass through the through hole 61, the upper receiving hole 112, the through hole 31 and the lower receiving hole 212 from top to bottom. The upper receiving hole 112 and the lower receiving hole 212 are only used to provide space for the pull rod 4 to pass through, making machining simpler. Therefore, the second embodiment can reduce the processing difficulty of the upper beam 1 and the lower beam 2, and further save costs.

[0038] See Figure 7 and Figure 8 The present invention discloses a third embodiment. In the third embodiment, the through hole 31 is divided into multiple regions, each region is separated by a partition plate 311, and multiple tie rods 4 are evenly distributed in each region. Compared with the method in the first and second embodiments where all tie rods 4 are evenly distributed, the regional method can strengthen the support at different positions according to the different cross sections of the sleeve 3, making the design of the sleeve 3 more flexible.

[0039] In all the above embodiments, the horizontal cross-section of the sleeve 3 is rectangular. Traditional brick presses typically use a cylindrical sleeve 3' to achieve a guiding function. However, a cylindrical shape has a small bearing area, limiting cross-sectional design. To achieve high strength and good performance, the diameter needs to be very large. In this invention, since the sleeve 3 does not need to guide, it can be rectangular, increasing the bearing area and allowing for flexible, unrestricted design. In other embodiments, it can also be configured with other shapes that facilitate guidance, such as triangles or semicircles.

[0040] 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.
