In addition, the shaft head structure is improved to increase the shaft head diameter, which improves the connection stability of the boot sleeve mounting disc and prolongs the service life of the center beam.

[0026] Exemplary embodiments of the present application will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0027] Referring to the drawings Figures 1 to 6 As shown in the drawings, the center beam 1 of the present embodiment adopts a whole flat structure, and the height of the middle section 11 of the flat structure is greater than the height of the two side end portions 12. The middle section 11 of the flat structure is located inside the boot of the boot press device, and the two side end portions 12 of the flat structure are used to connect with the mounting disc 10 of the boot.

[0028] In the present embodiment, the thickness of the whole flat of the center beam 1 is uniform, and the thickness is preferably less than or equal to 300 mm. The thickness is much lighter than the thickness of the existing I-shaped center beam structure, which is generally above 600 mm, and can provide a large space for the installation of the peripheral equipment of the center beam, so that the internal structure of the whole boot is more reasonable and simple, and easy to disassemble and maintain. Moreover, the height of the center beam 1 can be increased compared with 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 a whole structure, the shaft head at both ends is integrally arranged with the middle portion, which not only reduces the complexity 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 whole flat structure is easier to process and lighter in weight, which is not only beneficial to transportation, but also greatly reduces the cost, and the cost is reduced by more than 40% compared with the existing I-shaped center beam.

[0029] Specifically, as shown in the drawings Figure 1 and 2 As shown in the drawings, a plurality of bolt mounting holes 111 are arranged on the two side surfaces of the middle section 11 of the center beam, and a through hole 112 for communicating the two side surfaces of the center beam is further arranged on the middle section 11. A center hole 113 communicating with the through hole 112 is arranged at one end of the center beam 1 close to the through hole 112, for the oil, gas, wire, etc. of the driving side shaft head to pass through.

[0030] Further improvement is that the two end portions of the center beam 1 are provided with a conversion connecting mechanism 13 for connecting with the circular mounting disc 10 of the two end portions of the boot, which can convert the square shaft end surface of the flat center beam into a cylindrical end surface, which is beneficial to the cooperation and connection with the existing boot mounting disc.

[0031] Referring to the drawings Figures 4 to 6As shown, the conversion connecting mechanism 13 in the embodiment includes fixing blocks 131, a conversion sleeve 132, and a transition ring 133. The fixing blocks 131 are two in number and are fixed on both sides of the end portions of the center beam 1. The conversion sleeve 132 is provided with a square hole 1321 matching the outer periphery of the end portion 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 fixing block 131, so as to realize the fixing of the conversion sleeve 132 and the center beam 1. The outer periphery of the conversion sleeve 132 is circular, for fixed connection with the transition ring 133, and the outer periphery of the transition ring 133 is a cylindrical finish surface in a cylindrical shape, for connection with the circular mounting disc 10 at both end portions of the shoe sleeve. The conversion connecting mechanism 13 is provided with a square hole in the conversion sleeve and a circular structure at the outer periphery, so as to realize the conversion of the square shaft end face of the flat plate type center beam into a cylindrical end face, so as to meet the matching connection with the existing shoe sleeve mounting disc. Moreover, the conversion sleeve 132 is separately provided from the center beam 1, so that the outer diameter of the conversion sleeve is not limited by the thickness of the center beam, and the outer diameter of the conversion sleeve 132 and the transition ring 133 can be increased, so as to improve the connection stability with the circular mounting disc 10, so as to achieve the effect of good stability of the shoe sleeve mounting disc.

[0032] In the embodiment, the square hole 1321 is arranged away from the center of the conversion sleeve 132, that is, the conversion sleeve 132 is a eccentric disc structure, as shown in the accompanying drawings. Figure 4 The eccentric disc structure is beneficial to the arrangement of the conversion sleeve 132, and the conversion sleeve 132 is further provided with an adjusting hole 1323 in the embodiment. The adjusting hole 1323 is used for the penetration of an adjusting tool, so as to provide convenience for the subsequent adjustment of the internal structure of the shoe sleeve.

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

[0034] A more preferred embodiment is that, as shown in the accompanying drawings, Figure 5 The end portions of the center beam 1 are arranged in a decreasing structure with at least one step 121, the square hole 1321 is arranged in a counterbore structure, and the counterbore structure abuts against the step 121 of the center beam, so as to better ensure the positioning and fixing 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 arranged in an integral structure, that is, a whole conversion end cover, which is more beneficial to installation and disassembly.

[0036] The flat plate type shoe roll center beam is used as the center beam of the shoe type pressing device, which is simple in structure, beneficial to installation of internal components of the shoe cover and beneficial to machining. The flat plate type shoe roll center beam can be directly made of a thick steel plate, is easy to obtain materials, has a short production cycle and can shorten the machining time by more than 50% compared with the I-shaped center beam. The flat plate type center beam can also be made by forging. Because the thickness is thinned, the center beam is more easily forged through in the forging process and does not have forging defects. Compared with the welded I-shaped center beam, the flat plate type center beam has higher structural strength and longer service life because welding is not needed, and part deformation and stress problems caused by welding are reduced.

[0037] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications to the above disclosed technical contents, and all fall within the protection scope of the present application.
