Description

Technical Field

[0001] This application relates to the field of H-beam steel component processing technology, specifically to a hot pressing forming device for H-beam steel components. Background Technology

[0002] H-beams are steel structural members with an H-shaped cross-section. They possess excellent mechanical and processing properties and are widely used in construction, bridges, shipbuilding, and machinery manufacturing. They consist of two parallel flanges and a vertically connected web. They have high load-bearing capacity and bending strength. When thermoforming a blank with good thermoplasticity, products of specified specifications can be produced according to the forming shape of the thermoforming mold.

[0003] However, it has been found in existing hot pressing forming equipment for H-beams that, when hot pressing forming H-beams, the specifications and dimensions of the H-beams used and processed are different. The existing hot pressing forming equipment cannot quickly change the mold, resulting in long mold change time and affecting production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a hot pressing forming device for H-beam steel components, which has the advantages of being able to quickly change molds. This solves the problem that existing hot pressing forming devices cannot quickly change molds, resulting in long mold change times and affecting production efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a hot pressing forming device for H-shaped steel components, comprising a mounting plate and two guide rails. A worm gear is rotatably connected to the inner wall of the mounting plate, and two worm wheels mesh with the outer surface of the worm gear. A threaded cylinder is fixedly connected to the inner wall of each worm wheel, and two threaded rods are threadedly connected to the inner wall of each threaded cylinder. A limit block is fixedly connected to the opposite end of each threaded rod. A slider is slidably mounted on the outer surface of each guide rail, and two connecting blocks are fixedly connected to the adjacent side of each slider. The inner wall of each connecting block is slidably connected to the outer surface of the corresponding limit block.

[0006] The above scheme enables rapid mold replacement and facilitates the hot pressing of H-beams of different specifications. By installing sliders on the surface of the guide rail and fixing the connecting block to the side of the two sliders that are close to each other, when replacement is needed, the mold is pulled out via the guide rail and sliders. Then, the worm gear is rotated, causing the two worm wheels to rotate. The worm wheels drive the corresponding threaded cylinder to rotate. Through the connection between the threaded cylinder and the corresponding threaded rod, the two threaded rods can move relative to each other, thereby causing the threaded rod to move the corresponding limiting block. The limiting block is then pulled out of the corresponding connecting block, allowing the mold and mounting plate to be disassembled. During installation, the mold of the specified specification is placed corresponding to the connecting block, and the worm gear is reversed so that the limiting block can connect with the connecting block, enabling rapid mold replacement and facilitating the hot pressing of H-beams of different specifications.

[0007] Furthermore, the mounting plate has two cavities inside, and the inner wall of each cavity is slidably connected to the outer surface of the corresponding limiting block. A mounting base is provided below the mounting plate.

[0008] The above solution involves creating a cavity inside the mounting plate to locate the cavity. The surface of the corresponding limiting block is connected to the corresponding cavity in a sliding connection. This ensures that the limiting block slides while the threaded rod does not rotate, allowing the two threaded rods to move relative to each other by rotating the threaded cylinder. The mounting base is then placed below the mounting plate to support the components above.

[0009] Furthermore, each cavity has two fixing blocks fixedly connected to its inner wall, and the inner wall of each fixing block is rotatably connected to the outer surface of the corresponding threaded cylinder.

[0010] The above scheme involves installing the fixing block on the inner wall of the corresponding cavity, setting it as a fixed connection to achieve the positioning and installation of the fixing block, and connecting the inner wall of the fixing block to the corresponding threaded cylinder, setting it as a rotating connection, so that the worm can rotate the threaded cylinder through the connection with the worm wheel.

[0011] Furthermore, a lower mold is fixedly connected to the upper surface of the mounting plate, and a heating wire is provided on the inner wall of the lower mold.

[0012] The above scheme involves placing the lower mold on the upper surface of the mounting plate. The lower mold is used to hold the heated billet, and the inner wall of the lower mold is the outline of the H-beam steel component. The inner wall outline of the lower mold allows for hot pressing of H-beam steel components of a specified size. The heating wire is placed on the inner wall of the lower mold, which can preheat the lower mold and prevent the billet from dropping in temperature rapidly when it comes into contact with the lower mold, thus preventing any impact on the fluidity of the steel.

[0013] Furthermore, the bottom surface of each guide rail is fixedly mounted to the upper surface of the mounting base, and a mounting bracket is fixedly connected to the upper surface of the mounting base.

[0014] The above solution connects the bottom surface of the guide rail to the upper surface of the mounting base to install the guide rail. The connection between the guide rail and the slider facilitates the removal of the lower mold and the extraction of the formed H-shaped steel component. The mounting bracket is then fixed to the upper surface of the mounting base to provide support for the mounting bracket.

[0015] Furthermore, the upper surface of the mounting bracket is fixedly connected with guide rods arranged at equal intervals, and the outer surface of the mounting bracket is fixedly connected with a mounting shell.

[0016] The above scheme installs guide rods on the upper surface of the mounting frame, achieving the positioning and installation effect of the guide rods. A total of four guide rods are provided, which fix the mounting shell to the outer surface of the mounting frame, thus realizing the installation of the mounting shell.

[0017] Furthermore, a hydraulic rod is fixedly mounted on the upper surface of the mounting shell, and a fixing plate is fixedly connected to the output end of the hydraulic rod.

[0018] The above method involves installing a hydraulic rod on the upper surface of the mounting housing and fixing a fixing plate to the output end of the hydraulic rod. The fixing plate can be raised and lowered by extending and shortening the hydraulic rod.

[0019] Furthermore, an upper mold is fixedly installed on the bottom surface of the fixing plate, and the outer surface of each guide rod is slidably connected to the inner wall of the fixing plate.

[0020] The above scheme involves placing the upper mold below the fixed plate and fixing it with bolts. The upper mold can be raised and lowered by the lifting of the fixed plate. The surface of the guide rod is connected to the inner wall of the fixed plate in a sliding connection to limit the position of the fixed plate. The top of the guide rod is fixed to the bottom surface of the mounting shell to ensure a stable connection between the guide rod and the fixed plate.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This H-beam steel component hot pressing forming device, by setting up components such as a worm gear, worm wheel, threaded cylinder, and threaded rod, pulls the mold out through guide rails and sliders. Then, rotating the worm gear causes the worm wheel to rotate, which in turn drives the threaded cylinder to rotate. Through the connection between the threaded cylinder and the threaded rod, two limit blocks can be disengaged from their corresponding connecting blocks. At this point, the mounting plate and mold can be disassembled, and a new mold can be installed. This device facilitates the replacement of molds of different specifications, shortens mold change time, and improves production efficiency. The guide rails and sliders also make it easy for operators to remove the formed H-beam steel components, improving operational convenience. Attached Figure Description

A limit block 6 is fixedly connected to the opposite end of each threaded rod 5. A slider 9 is slidably installed on the outer surface of each guide rail 8. Two connecting blocks 7 are fixedly connected to the opposite side of each slider 9. The inner wall of each connecting block 7 is slidably connected to the outer surface of the corresponding limit block 6.

[0032] Please see Figure 4The mounting plate 1 has two cavities 10 inside. The inner wall of each cavity 10 is slidably connected to the outer surface of the corresponding limiting block 6. The mounting plate 1 has a mounting base 14 below it. The cavity 10 is opened inside the mounting plate 1 to position the cavity 10. The surface of the corresponding limiting block 6 is connected to the corresponding cavity 10 in a sliding connection. This ensures that the limiting block 6 slides while the threaded rod 5 does not rotate. This allows the two threaded rods 5 to move relative to each other by rotating the threaded cylinder 4. The mounting base 14 is placed below the mounting plate 1 to support the components above it.

[0033] Please see Figure 4 Each cavity 10 has two fixed blocks 11 fixedly connected to its inner wall.

The fixed blocks 11 are installed on the inner wall of the corresponding cavity 10 to achieve fixed connection and positioning of the fixed blocks 11. The inner wall of the fixed blocks 11 is connected to the corresponding threaded cylinder 4 to achieve rotatable connection, so that the worm 2 can rotate the threaded cylinder 4 through the connection with the worm wheel 3.

[0034] Please see Figure 1 , Figure 3 and Figure 4 A lower mold 12 is fixedly connected to the upper surface of the mounting plate 1. A heating wire 13 is provided on the inner wall of the lower mold 12. The lower mold 12 is set on the upper surface of the mounting plate 1. The lower mold 12 is used to hold the heated billet.

The H-beam steel component of a specified size can be hot-pressed through the outline of the inner wall of the lower mold 12. The heating wire 13 is set on the inner wall of the lower mold 12. The heating wire 13 can preheat the lower mold 12 and prevent the temperature of the billet from dropping sharply when it comes into contact with the lower mold 12, thus preventing the flowability of the steel from being affected.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The bottom surface of each guide rail 8 is fixedly installed on the upper surface of the mounting base 14. The upper surface of the mounting base 14 is fixedly connected to the mounting bracket 15.

Through the connection between the guide rail 8 and the slider 9, the lower mold 12 can be easily pulled out, and the formed H-shaped steel component can be easily removed. The mounting bracket 15 is fixed on the upper surface of the mounting base 14 to realize the support of the mounting bracket 15.

[0036] Please see Figure 5The upper surface of the mounting bracket 15 is fixedly connected with guide rods 16 arranged at equal intervals, and the outer surface of the mounting bracket 15 is fixedly connected with a mounting shell 17. The guide rods 16 are on the upper surface of the mounting bracket 15 to achieve the positioning and installation effect of the guide rods 16. There are four guide rods 16 in total, which fix the mounting shell 17 to the outer surface of the mounting bracket 15 to achieve the installation of the mounting shell 17.

[0037] Please see Figure 1 , Figure 2 and Figure 5 A hydraulic rod 18 is fixedly installed on the upper surface of the mounting shell 17.

The hydraulic rod 18 is installed on the upper surface of the mounting shell 17, and the fixing plate 19 is fixed to the output end of the hydraulic rod 18. The fixing plate 19 can be raised and lowered by the extension and retraction of the hydraulic rod 18.

[0038] Please see Figure 3 and Figure 5 An upper mold 20 is fixedly installed on the bottom surface of the fixed plate 19. The outer surface of each guide rod 16 is slidably connected to the inner wall of the fixed plate 19. The upper mold 20 is set below the fixed plate 19 and fixed by bolts. The upper mold 20 can be raised and lowered by the lifting of the fixed plate 19, and the surface of the guide rod 16 is connected to the inner wall of the fixed plate 19 in a sliding connection to limit the position of the fixed plate 19. The top end of the guide rod 16 is fixed to the bottom surface of the mounting shell 17, so that the guide rod 16 is stably connected to the fixed plate 19.

[0039] This embodiment of an H-beam steel component hot pressing forming device, by setting up components such as worm 2, worm wheel 3, threaded cylinder 4, and threaded rod 5, pulls out the mold through guide rail 8 and slider 9. Then, rotating worm 2 causes worm wheel 3 to rotate, which drives threaded cylinder 4 to rotate. Through the connection between threaded cylinder 4 and threaded rod 5, two limiting blocks 6 can be disengaged from the corresponding connecting blocks 7. At this time, mounting plate 1 and mold can be disassembled, and a new mold can be installed. This device makes it easy to change molds of different specifications, shortens mold change time, and improves production efficiency. By setting guide rail 8 and slider 9, it is easy for operators to remove the formed H-beam steel component, improving the convenience of operation.

[0040] It should be noted that the hydraulic rod 18 is hydraulically driven. The heated blank is placed in the lower mold 12, and the upper mold 20 is lowered by the hydraulic rod 18. When it matches the lower mold 12, the blank can be hot-pressed into shape to realize the processing of H-beam steel components.

[0041] The working principle of the above embodiments is as follows:

[0042] First, the lower mold 12 is heated by the heating wire 13. Then, the heated blank is placed inside the lower mold 12. The hydraulic rod 18 is activated to lower the upper mold 20 until it is fitted with the lower mold 12. At this time, the H-beam is hot-pressed and formed. The upper mold 20 is reset. The lower mold 12 is pulled out by the guide rail 8 and the slider 9. The formed H-beam can then be removed. When the mold needs to be replaced, the upper mold 20 is replaced by bolts. Then, the worm gear 2 is rotated to make the worm wheel 3 rotate. The worm wheel 3 drives the threaded cylinder 4 to rotate. The fixed block 11 limits the threaded cylinder 4. The connection between the threaded cylinder 4 and the threaded rod 5 allows the two limiting blocks 6 to slide on the inner wall of the cavity 10, thereby allowing the corresponding connecting block 7 to be removed. At this time, the mounting plate 1 and the lower mold 12 can be disassembled, and a new lower mold 12 can be installed. This device makes it easy to replace molds of different specifications, shortens the mold change time, and improves production efficiency.
