Description

Technical Field

[0001] The invention relates to the technical field of shoe presses, in particular to a flat shoe roller center beam and a shoe press device comprising the same. Background Art

[0002] At present, the center beam structure of the shoe press at home and abroad basically adopts an I-shaped structure, such as the center beam in the prior art CN107964821B and the beam body in the prior art CN207633122U, which are both I-shaped beams welded from four side panels. The I-shaped center beam occupies a large space, which makes the installation space inside the shoe sleeve and around the shoe roller narrow and crowded, which is not conducive to the installation of its internal accessories, and will lead to a complicated structure after the accessories are installed, and it is not convenient for later repair and maintenance. In addition, since the existing I-shaped center beam is welded from four upper, lower, left and right side panels, it also needs to be fixedly connected to the shaft heads on both sides, which is difficult to process, has a long production cycle, high cost, and a large overall weight. In addition, the existing center beam structure is limited by the thickness of the I-shaped center beam, which makes the shaft head diameter of the shoe sleeve mounting plate position on both sides of the I-shaped center beam small, resulting in poor connection stability of the boot sleeve mounting plate, affecting the service life.

[0003] It can be seen that the above-mentioned existing I-shaped structure of the center beam of the shoe roller obviously still has inconveniences and defects in structure, method and use, and it is urgent to be further improved. This application is to create a new flat-plate center beam of the shoe roller and a shoe-type pressing device including it in response to the existing technology, so that it breaks through the existing I-shaped beam structure and adopts an integral flat-plate structure beam, which is not only simple to process, low in difficulty, and greatly reduces the cost, but also because the thickness of the beam is reduced, the space on both sides becomes larger, which is conducive to the installation and maintenance of peripheral equipment; the shaft head structure is improved and the shaft head diameter is increased, so that the connection stability of the shoe sleeve mounting plate is improved, and the service life of the center beam is extended. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a flat-plate shoe roller center beam, which breaks through the existing I-beam structure and adopts an integral flat-plate structural beam. It is not only simple to process, low in difficulty and greatly reduces the cost, but also because the thickness of the beam is reduced, the space on both sides becomes larger, which is conducive to the installation and maintenance of peripheral equipment; the shaft head structure is improved and the shaft head diameter is increased, so that the stability of the shoe sleeve mounting plate is improved and the service life of the center beam is extended, thereby overcoming the shortcomings of the existing I-shaped shoe roller center beam.

[0005] In order to solve the above technical problems, the present invention provides a flat-plate shoe roller center beam, wherein the center beam adopts an integral flat plate structure, and the height of the middle section of the flat plate structure is greater than the height of the two side ends thereof.

[0006] As a further improvement, a plurality of bolt mounting holes are provided on both side surfaces of the middle section of the center beam, and a through hole for connecting the two side surfaces of the center beam is also provided on the middle section, and a center hole communicating with the through hole is provided at one end of the center beam close to the through hole.

[0007] As a further improvement, both ends of the central beam are provided with conversion connection mechanisms for connecting with circular mounting plates at both ends of the boot sleeve.

[0008] Further improvement, the conversion connection mechanism includes a fixed block, a conversion sleeve and a transition ring, the fixed block includes two, which are respectively fixed on both sides of the end of the center beam, the conversion sleeve is provided with a square hole matching the outer periphery of the end of the center beam, the outer periphery of the square hole is provided with a plurality of bolt fixing holes for fixing the conversion sleeve on the end face of the fixed block, so as to achieve the fixation of the conversion sleeve to the center beam, the outer periphery of the conversion sleeve is circular, which is used for fixed connection with the transition ring, and the outer periphery of the transition ring is cylindrical, which is used for connecting with the circular mounting plates at both ends of the boot sleeve.

[0009] As a further improvement, the square hole is arranged offset from the center of the conversion disk, and the conversion disk is also provided with an adjustment hole for an adjustment tool to pass through.

[0010] As a further improvement, the outer periphery of the conversion sleeve is configured as a cylindrical stop structure, and one end of the transition ring is fixedly connected to the cylindrical stop structure.

[0011] As a further improvement, both ends of the center beam are configured as a decreasing structure having at least one step, and the square hole is configured as a countersunk hole structure, and the countersunk hole structure abuts against the step structure of the center beam.

[0012] As a further improvement, the conversion sleeve and the transition ring are an integrated structure.

[0013] As another improvement of the present invention, the present invention also provides a shoe press device, including the above-mentioned flat shoe roller center beam.

[0014] After adopting such a design, the present invention has at least the following advantages:

[0015] 1. The flat-plate shoe roller center beam of the present invention improves the existing I-shaped center beam into an integral flat-plate structural beam, which not only reduces the cumbersomeness of the existing shaft head installation, but also improves the overall strength of the center beam as a whole. It is simpler to process, lighter in weight, and easier to transport. The cost is also greatly reduced, which is more than 40% lower than the cost of the existing I-shaped center beam. Moreover, due to the thinning of the flat-plate structure, a large space is provided for the installation of peripheral equipment of the center beam, making the internal structure layout of the entire shoe sleeve more reasonable, simpler, and easy to disassemble and maintain.

[0016] 2. By setting the conversion connection mechanism at both ends, the two ends of the beam no longer need to be forged, cast or welded with round ends much larger than the thickness of the beam, which reduces the manufacturing and processing costs, reasonably solves the problem of rotation and sealing of the boot sleeve end cover at the square shaft head, and satisfies the matching connection with the existing boot sleeve mounting plate. In addition, the outer diameter of the conversion sleeve and the transition ring is not limited by the thickness of the center beam, and the outer diameter can be enlarged, which greatly improves the connection stability with the boot sleeve mounting plate and prolongs the service life of the boot roller.

[0017] 3. By setting the conversion disk to an eccentric disk structure, it is more conducive to the layout of the internal components of the boot cover and the setting of the adjustment holes, providing convenient conditions for the subsequent adjustment of the internal structure of the boot cover.

[0018] 4. The flat center beam can be designed in a standardized manner, which can realize the standardization and modularization of peripheral accessories, improve production efficiency and product quality, and facilitate the later maintenance and upkeep of the equipment. The flat center beam can also reduce the weight of the shoe roller as a whole, and the requirements for the strength of the installation frame, transportation, factory crane, and on-site civil engineering foundation will also be reduced, thereby improving the safety and reliability of existing production and processing.

[0026] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0027] See attached Figures 1 to 6 As shown, the center beam 1 of the shoe roller in this embodiment adopts an integral flat plate structure, and the height of the middle section 11 of the flat plate structure is greater than the height of the two side ends 12. The middle section 11 of the flat plate structure is located inside the boot sleeve of the boot-type pressing device, and the two side ends 12 of the flat plate structure are used to connect with the boot sleeve mounting plate 10.

[0028] The entire plate thickness of the center beam 1 described in this embodiment is consistent, and the thickness is preferably less than or equal to 300mm. This thickness is much thinner than the thickness of the existing I-shaped center beam structure, which is generally more than 600mm, and can provide a lot of space for the installation of peripheral equipment of the center beam, making the internal structure layout of the entire boot sleeve more reasonable, simpler, and easy to disassemble and maintain. In addition, since the height of the center beam 1 is not limited by thickness, it can be increased compared to the height of the existing I-shaped center beam, so that the structural strength of the flat center beam is higher. Moreover, since the flat center beam is an integral structure, the shaft heads at both ends are integrally arranged with the middle part, which not only reduces the cumbersomeness of the existing shaft head installation, but also improves the overall strength of the center beam as a whole, and has a longer service life. In addition, the integral flat plate structure is simpler to process and lighter in weight, which is not only conducive to transportation, but also greatly reduces the cost, which is more than 40% lower than the cost of the existing I-shaped center beam.

[0029] Specifically, as attached Figure 1 and 2 As shown, a plurality of bolt mounting holes 111 are provided on both sides of the middle section 11 of the center beam, and a through hole 112 for connecting the two sides of the center beam is also provided on the middle section 11. A center hole 113 communicating with the through hole 112 is provided at one end of the center beam 1 close to the through hole 112 for passing oil, gas, wire, etc. of the transmission side shaft head.

[0030] A further improvement is that both ends of the center beam 1 are provided with a conversion connection mechanism 13 for connecting to the circular mounting plates 10 at both ends of the boot sleeve, which can convert the square axial end face of the flat center beam into a cylindrical end face, which is conducive to the matching connection with the existing boot sleeve mounting plate.

[0031] See attached Figures 4 to 6As shown, the conversion connection mechanism 13 in this embodiment includes a fixed block 131, a conversion sleeve 132 and a transition ring 133. The fixed block 131 includes two, which are fixed on both sides of the end of the center beam 1. The conversion sleeve 132 is provided with a square hole 1321 matching the outer periphery of the end 12 of the center beam, and the outer periphery of the square hole 1321 is provided with a plurality of bolt fixing holes 1322 for fixing the conversion sleeve 132 on the end face of the fixed block 131, so as to achieve the fixation of the conversion sleeve 132 and the center beam 1. The outer periphery of the conversion sleeve 132 is circular, which is used for fixed connection with the transition ring 133. The outer periphery of the transition ring 133 is a cylindrical finely machined cylindrical surface, which is used to connect with the circular mounting plates 10 at both ends of the boot sleeve. The conversion connection mechanism 13 can realize the function of converting the square shaft end face of the flat center beam into a cylindrical end face through the square hole in the conversion sleeve and the circular structure of the outer periphery, so as to meet the matching connection with the existing boot sleeve mounting plate. Moreover, since the conversion sleeve 132 and the center beam 1 are set separately, the outer diameter of the conversion sleeve is not limited by the thickness of the center beam, so the outer diameter of the conversion sleeve 132 and the transition ring 133 can be enlarged, thereby improving the connection stability with the circular mounting plate 10 and achieving good stability of the boot sleeve mounting plate.

[0032] In this embodiment, the square hole 1321 is arranged away from the center of the conversion disk 132, that is, the conversion disk 132 is an eccentric disk structure. Figure 4 The eccentric disc structure facilitates the arrangement of the conversion disc 132. In this embodiment, an adjustment hole 1323 is also provided on the conversion disc 132. The adjustment hole 1323 is used for an adjustment tool to pass through, which facilitates the subsequent adjustment of the internal structure of the boot cover.

[0033] In addition, the outer periphery of the conversion sleeve 132 in this embodiment is configured as a cylindrical stop structure 1324, and one end of the transition ring 133 is fixedly connected to the cylindrical stop structure 1324. Of course, the transition ring 133 can also be connected to the conversion sleeve 132 in any other existing manner.

[0034] A more preferred embodiment is as shown in the attached Figure 5 As shown, both ends of the center beam 1 are arranged as a decreasing structure with at least one step 121, and the square hole 1321 is arranged as a countersunk structure, which abuts against the step 121 of the center beam, and can better ensure the positioning and fixation of the conversion sleeve 132 and the center beam 1.

[0035] Of course, the conversion sleeve 132 and the transition ring 133 in the above embodiment can also be set as an integrated structure, that is, forming an integral conversion end cover, which is more convenient for installation and disassembly.

[0036] The use of the above-mentioned flat shoe roller center beam as the center beam of the boot-type pressing device is not only simple in structure and convenient for installation of the internal components of the boot sleeve, but also convenient for processing. The flat shoe roller center beam can be made directly from a thick steel plate, which is easy to obtain and has a short production cycle. Compared with the I-shaped center beam, the processing time of the flat center beam can be shortened by more than 50%. The flat center beam can also be made by forging technology. Because the thickness is thinner, it is easier to forge through during the forging process and no forging defects will occur. Compared with the welded I-shaped center beam, since welding is not required, the deformation and stress problems of parts caused by welding are reduced, the structural strength is higher, and the service life is longer.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which all fall within the protection scope of the present invention.
