Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment maintenance, in particular to a shaft sleeve disassembly tool used for sheet metal automatic processing equipment. Background Art

[0002] Sheet metal rolling lines are widely used as automated processing equipment for sheet metal parts. These lines consist of numerous sets of rolling wheels. During use, the rollers and wheels often wear out and require regular replacement. Replacement requires disassembling each roller component individually before replacing them. Several sleeves have a very small clearance between them and the shaft, approximately 0.01mm. Rust on the shaft surface increases friction and can even lead to rusting. This makes the sleeve difficult to remove due to the lack of a support point. Furthermore, due to the high hardness and thin walls of the sleeves, the retaining ring grooves are designed to be thin to minimize equipment space. Traditional methods, such as chisels and hammers, can easily crack the sleeves, causing unnecessary trouble. There is no clearance between the sleeves and the end faces of the rolling wheels, and wedges cannot be used. Consequently, each sleeve removal and installation is time-consuming and labor-intensive. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to provide a technical solution for facilitating the disassembly of a roller shaft sleeve in automatic sheet metal processing equipment.

[0004] In order to solve the above technical problems, the utility model provides a shaft sleeve disassembly tool for sheet metal automatic processing equipment, comprising a first semicircular ring, a second semicircular ring and a fastener; the inner wall of the first semicircular ring has a first positioning step, and the first positioning step matches the shaft sleeve retaining ring groove of the sheet metal automatic processing equipment; the inner wall of the second semicircular ring has a second positioning step, and the second positioning step matches the shaft sleeve retaining ring groove of the sheet metal automatic processing equipment; when the shaft sleeve is disassembled, the fastener fixes the first semicircular ring and the second semicircular ring on the shaft sleeve, so that the first positioning step and the second positioning step are stuck in the retaining ring groove of the shaft sleeve.

[0005] Preferably, at the connection between the first semicircular ring and the second semicircular ring, there is a threaded hole on the first semicircular ring and a stepped through hole on the second semicircular ring.

[0006] Compared with existing technologies, the sleeve removal tool provided by this utility model has a simple structure and is easy to use. It has a large force-bearing area between the sleeve and the tool, and the force is evenly distributed, preventing sleeve deformation and cracking. When used in conjunction with a hydraulic puller, the sleeve can be easily removed from the roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0008] Figure 1This is a three-dimensional schematic diagram of the structure of the sleeve removal tool of Example 1;

[0009] Figure 2 This is a schematic plan view of the structure of the sleeve removal tool of Example 1. DETAILED DESCRIPTION

[0010] The following describes the implementation methods of the present invention through specific specific embodiments. Those skilled in the art can fully understand the other advantages and technical effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through different specific implementation methods, and the various details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without deviating from the overall design concept of the utility model. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. The following exemplary embodiments of the present invention can be implemented in a variety of different forms and should not be interpreted as being limited to the specific embodiments described here. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0011] Example 1

[0012] like Figure 1 As shown, the sleeve removal tool for sheet metal automatic processing equipment provided in this embodiment includes a first semicircular ring 1, a second semicircular ring 2 and a fastener 3.

[0013] The first semicircular ring 1 has a first positioning step on its inner wall, which matches the sleeve retaining ring groove of the sheet metal automatic processing equipment. The second semicircular ring 2 has a second positioning step on its inner wall, which matches the sleeve retaining ring groove of the sheet metal automatic processing equipment.

[0014] The connection between the first and second semicircular rings 1 and 2 is characterized by a threaded hole in the first semicircular ring 1 and a stepped through-hole in the second semicircular ring 2. Fasteners 3 pass through the through-holes in the second semicircular ring and screw into the threaded holes, securing the first and second semicircular rings 1 and 2 to the sleeve, such that the first and second positioning steps engage the retaining ring grooves of the sleeve. Once secured, the end faces of the first and second semicircular rings 1 and 2 facing the rollers of the sheet metal processing equipment become fulcrums. By hooking a puller at these fulcrums, the sleeves can be easily removed from the rollers.

[0015] The present invention has been described in detail above through specific implementation methods and examples, but these do not constitute limitations of the present invention. Without departing from the principles of the present invention, those skilled in the art may make many variations and improvements, which should also be considered as the scope of protection of the present invention.
