Description

Technical Field

[0001] The utility model relates to the technical field of wire cold rolling processing, and particularly relates to a portable roll disassembly and assembly device. Background Art

[0002] In the production and processing of piston ring wires with different shapes and sizes, different cavities are generally rolled and processed by a rolling mill combined with different rolls. Among them, the design and cooperation of the rolls directly affect the forming quality of the wire products. The existing alloy roll assembly on the rolling mill generally consists of a roll ring, a roll shaft, and a roll gear. Since roll cold rolling is a processing method of rolling metal billets into various specifications of materials, its production belongs to pressure processing operations with relatively large load impact forces. Therefore, the roll surface is extremely prone to wear and needs to be ground and repaired or replaced frequently. At this time, the roll needs to be removed first, that is, when replacing the roll, six inner hexagon bolts connecting the roll shaft and the roll gear need to be removed to take out the roll ring to be replaced. However, due to the large size and heavy weight of the roll, it is impossible to operate alone by one person when disassembling the bolts and replacing the cemented carbide roll ring. Two people are required to assist in the disassembly and assembly. That is, one person needs to hold the entire roll assembly with both hands, and the other person uses the corresponding inner hexagon wrench to remove the bolts. The entire operation process is time-consuming and laborious. In addition, the above operation steps also need to be taken when reassembling the roll assembly to be installed. Therefore, the existing roll assembly disassembly and assembly scheme has many inconveniences and is difficult to be popularized and applied in enterprises. Content of the Utility Model

Specific embodiments

[0024] The following will give a detailed description of a preferred embodiment of the present utility model with reference to the accompanying drawings.

[0025] To achieve the above object, the embodiments of the present utility model adopt the following technical solutions: Referring to Figure 1 , Figure 2 , a portable roll disassembly and assembly device includes a base 10, which serves as the main support member. In addition, the portable roll disassembly and assembly device further includes a support 20, an engaging member 30, and a fixing assembly. Further, the support 20 is fixedly arranged on the top of the base 10, and the engaging member 30 is horizontally placed on the top of the support 20 for being clamped and fixed with the roll gear. The fixing assembly includes a support rod 410 and a locking member 420. The support rod 410 is fixedly arranged on the side wall of the support 20 and vertically extends upward to a position above the top of the engaging member 30. The locking member 420 is arranged on the support rod 410 and is used for vertically fixing the roll on the engaging member 30. When in use, when it is necessary to replace and disassemble the roll ring, the roll assembly formed by the combination of the roll gear, the roll shaft, and the roll ring is integrally installed on the aforementioned roll disassembly and assembly device, and the roll gear is clamped and fixed with the engaging member to fix the roll gear. Subsequently, the locking member in the fixing assembly is used to lock and fix the roll assembly vertically to make the roll reach a stable state. At this time, a single person can disassemble and replace the roll ring. Therefore, the entire roll ring disassembly and assembly operation is simple and the work efficiency is high.

[0026] As a preferred technical solution of this embodiment, the base 10 includes a support plate 110 and support legs 120. The number of support legs 120 is four, and the four support legs 120 are fixedly arranged at the four corners of the bottom of the support plate 110, thereby achieving the effect of stably supporting the support and the components thereon.

[0027] As a preferred technical solution of this embodiment, the support 20 is specifically U-shaped. The U-shaped support 20 includes a horizontal section and vertical sections integrally formed with the horizontal section. The vertical sections are two relatively arranged ones and vertically extend upward from the ends of the horizontal section. In actual use, the horizontal section of the support 20 is arranged on the top of the support plate 110 and can be specifically connected to the support plate through fasteners such as bolts.

[0028] Further, the engaging member 30 includes a ring body and engaging grooves 310 uniformly formed in the circumferential direction along the inner side wall of the ring body. Specifically, the cross-section of the engaging groove 310 is triangular. In this way, a ring-shaped groove body for meshing with the roll gear is formed inside the engaging member. When the roll assembly needs to be integrally installed on the roll disassembly and assembly device, the teeth of the roll gear can be engaged with the engaging grooves described above to fix the roll assembly.

[0029] Referring to Figure 3 、 Figure 4 As a preferred technical solution of this embodiment, the support rod 410 includes a connecting block 411, a support block 412 and a mounting block 413. The connecting block 411 is fixedly connected to the support 20. Specifically, the connecting block is fixedly connected to the side wall of the vertical section of the support. The support block 412 is fixedly connected to the connecting block 411, and the support block 412 extends vertically upward from the connecting block 411. The mounting block 413 is horizontally and fixedly arranged inside the support block 412, and this mounting block is used for mounting the locking member.

[0030] Further, the locking member 420 includes a locking column 421 and a driving column 422. The locking column 421 is arranged in a vertical thread on the mounting block 413, that is, the locking column can move spirally along the mounting block. The driving column 422 is fixedly arranged on the top of the locking column 421, and the driving column 422 is used to drive the locking column 421 to move spirally. When in use, the roll assembly formed by combining the roll gear, the roll shaft and the roll ring is integrally installed inside the engaging member. At this time, the driving column 422 is used to drive the locking column 421 to move spirally along the mounting block 413, so that the bottom of the locking column 421 abuts against the roll assembly to achieve the fixing effect of the roll assembly.

[0031] Further, in order to improve the stability of driving the locking column 421 to move along the mounting block 413, the locking column 421 is a threaded column, and a threaded hole 414 matching the locking column 421 is formed in the mounting block 413. In this way, the locking column 421 can be driven to move stably along the mounting block 413 under the drive of the driving column 422.

[0032] When in use, when the roll ring needs to be replaced and disassembled, the roll assembly formed by combining the roll gear, the roll shaft and the roll ring is integrally installed on the aforementioned roll disassembly and assembly device, and the teeth of the roll gear are engaged and fixed with the engaging grooves 310 to fix the roll gear. Subsequently, by operating the driving column 422, the locking column 421 is driven to move spirally along the mounting block 413. When the bottom of the locking column 421 contacts the roll assembly, the roll assembly is locked and fixed vertically, so that the roll reaches a stable state. At this time, a single person can remove the bolts on the roll assembly to achieve the purpose of disassembling the roll ring.

[0033] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
