Description

Technical Field

[0001] This utility model belongs to the field of wire cutting machines, and specifically relates to a protective structure for a wire feeding component. Background Technology

[0002] Wire EDM machines include wire feeding components. Since the wire feeding components have a significant impact on cutting accuracy, they need to be adequately protected. Existing protective covers for wire feeding components typically consist of two layers: an outer protective cover mounted on the bottom cover and an inner protective cover independently mounted on the base of the wire feeding component. Therefore, when maintenance or other operations are required, both the outer and inner protective covers need to be opened separately, which is inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a protective structure for a wire feeding component that provides double-layer protection and is easy to open and close.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a protective structure for a wire feeding component, comprising a bottom cover, a first sliding cover slidably connected to the bottom cover, a first fixed cover fixed to the bottom cover, and a second sliding cover. The front end of the second sliding cover is fixed to the top inner wall of the first sliding cover by a connecting plate. An open mounting space is formed between the second sliding cover, the connecting plate, and the top of the first sliding cover, facing the rear end of the first sliding cover. The first fixed cover is located within the mounting space and on the rear end of the bottom cover. When the first sliding cover slides to the front end of the bottom cover, the rear end of the second sliding cover is located below the front end of the first fixed cover. When the first sliding cover slides to the rear end of the bottom cover, the front end of the second sliding cover is located below the front end of the first fixed cover.

[0005] In another embodiment, the upper surface of the bottom cover is provided with a first guide rail with a groove that is wider at the bottom and narrower at the top. The cross-section of the first sliding cover is U-shaped, and a T-shaped first sliding block matching the groove of the first guide rail is provided on its lower right end. The first sliding block is slidably connected to the groove of the first guide rail. This prevents the first sliding cover from falling off along the length direction perpendicular to the first guide rail.

[0006] In another embodiment, the second sliding cover is L-shaped, including a horizontally arranged second upper sliding plate and a vertically arranged second lower sliding plate to the right of the second upper sliding plate. A downwardly protruding first guide strip is formed on the second upper sliding plate, and a second guide rail is provided on the wire feeding roller bracket of the wire feeding component. The first guide strip is slidably connected to the second guide rail. This not only improves the strength of the second upper sliding plate itself, but also ensures the stability of the second sliding cover as it slides with the first sliding cover.

[0007] In another embodiment, the protective structure further includes a third guide rail disposed on the base of the wire feeding component, and the lower end of the second sliding plate is U-shaped and slidably disposed within the third guide rail. This enhances the stability of the second sliding cover.

[0008] In another embodiment, the protective structure further includes a guide block fixed to the upper end of the first fixed cover and guide slide rods connected at both ends to the lower end face of the top of the first sliding cover, the guide slide rods passing through the guide block.

[0009] In another embodiment, a sliding roller is provided on the front end of the first sliding cover. When the front end of the first sliding cover passes the wire feeding roller bracket of the wire feeding component, the sliding roller contacts the upper surface of the wire feeding roller bracket of the wire feeding component, so that the first sliding cover can move more smoothly.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: when the first sliding cover is at the front end, the second sliding cover and the first fixed cover can completely cover the wire conveying roller in the direction facing the circumferential surface of the wire conveying roller in the wire conveying component. Combined with the first sliding cover, the wire conveying roller can be protected by a double layer. Moreover, the second sliding cover moves with the first sliding cover. Only the first sliding cover needs to be moved to complete the closing and opening of the first and second sliding covers. The operation is convenient and the protection effect is good.

[0015] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] like Figure 1-4As shown, the protective structure of the wire feeding component includes a bottom cover 0, a first sliding cover 1 slidably connected to the bottom cover 0, a first fixed cover 2 fixed to the bottom cover 0, and a second sliding cover 3. The front end of the second sliding cover 3 is fixed to the top inner wall of the first sliding cover 1 by a connecting plate 4. An open mounting space is formed between the second sliding cover 3, the connecting plate 4, and the top of the first sliding cover 1, facing the rear end of the first sliding cover 1. The first fixed cover 2 is located in the mounting space and is located on the rear end of the bottom cover 0. When the first sliding cover 1 slides to the front end of the bottom cover 0, the rear end of the second sliding cover 3 is located below the front end of the first fixed cover 2. When the first sliding cover 1 slides to the rear end of the bottom cover 0, the front end of the second sliding cover 3 is located below the front end of the first fixed cover 2.

[0017] The upper surface of the bottom cover 0 is provided with a first guide rail 5 with a groove that is wider at the bottom and narrower at the top. The cross-section of the first sliding cover 1 is U-shaped, and a T-shaped first sliding block 8 matching the groove of the first guide rail 5 is provided on the lower right end of the first sliding cover 1. The first sliding block 8 is slidably connected in the groove of the first guide rail 5, which can prevent the first sliding cover 1 from falling off along the length direction perpendicular to the first guide rail 5. The second sliding cover 3 is L-shaped, including a horizontally arranged second upper slide plate 9 and a second lower slide plate 10 vertically arranged on the right side of the second upper slide plate 9. A downwardly protruding first guide strip 11 is formed on the second upper slide plate 9. The wire feeding roller bracket C of the wire feeding component is provided with a second guide rail 6, and the first guide strip 11 is slidably connected in the second guide rail 6.
