Description

Technical Field

[0001] This utility model relates to the technical field of multi-wire cutting equipment, specifically a waterproof structure for the swing shaft of a swing-type multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting machines are slicing equipment that uses the high-speed reciprocating motion of cutting wires to grind the cutting material with abrasive, simultaneously cutting the workpiece into hundreds or even thousands of thin slices. Diamond wire multi-wire cutting machines use diamond wire as the cutting wire. Diamond wire is made by bonding diamond particles to the cutting wire. In its wire feeding system, the diamond wire is wound around a grooved wheel according to the cutting process requirements to form a parallel cutting wire mesh. During operation, the grooved wheel drives the cutting wire to reciprocate and cut the workpiece. Simultaneously, coolant is sprayed to cool the cutting wire and remove debris and impurities from the cut. With the increasing diversity of cutting materials and workpiece sizes, the structure of multi-wire cutting machines is constantly being innovated. For example, some products require a workpiece oscillation method for cutting. In this case, the worktable oscillation multi-wire cutting machine has emerged. However, due to the spraying of coolant, a thick water mist is generated in the cutting chamber, making the waterproofing of the oscillation shaft a significant factor affecting the bearing's lifespan and also impacting the quality of the cut product.

[0003] In the existing technology, in order to solve the waterproofing problem of the swing shaft of the worktable swing-type multi-wire cutting machine, sealing structures such as sealing rings and rubber oil seals are usually used. However, for the harsh water mist environment in the cutting chamber of the diamond wire multi-wire cutting machine, it is difficult to achieve a satisfactory waterproofing effect by relying solely on sealing rings and rubber oil seals. Utility Model Content

[0004] This utility model provides a waterproof structure for the swing shaft of a swing-type multi-wire cutting machine. It aims to cope with the harsh water mist environment inside the cutting chamber of the diamond wire multi-wire cutting machine by using a combination of sealing rings, rubber oil seals and labyrinth waterproof components, so as to provide all-round protection for the swing shaft, extend the service life of the swing bearing and improve the cutting quality of the workpiece.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof structure for the swing shaft of a swing-type multi-wire cutting machine includes a sealing ring, a rubber oil seal, and a labyrinth-type waterproof component. The sealing ring is fitted onto the drive-side and operating-side swing shafts of the swing worktable and is embedded in the sealing groove of the bearing inner cover. The rubber oil seal is fitted onto the inner end of the operating-side swing shaft of the swing worktable and is embedded between the expansion sleeve cover of the operating-side swing shaft and the operating-side swing shaft. The labyrinth-type waterproof component consists of a waterproof cover plate and a waterproof baffle. The waterproof cover plate is fixed to the worktable frame of the swing-type multi-wire cutting machine and has a swing shaft through hole. The waterproof baffle is an annular baffle, fixed to the swing body of the worktable, and fitted onto the outside of the swing shaft. The waterproof baffle and the waterproof cover plate cooperate to form a labyrinth-type water mist passage channel.

[0007] The aforementioned waterproof structure for the swing shaft of the swing-type multi-wire cutting machine includes a flanged baffle cap with a bottom opening around the perimeter of the waterproof cover plate. The baffle cap covers the outside of the baffle plate but does not contact it, leaving a gap between them.

[0008] The above-mentioned oscillating multi-wire cutting machine oscillating shaft waterproof structure has a semi-circular annular groove at the top of the baffle cover cap that opens inward, and vertical grooves arranged symmetrically on the left and right at the bottom. The semi-circular annular groove connects with the two vertical grooves on the left and right. The waterproof baffle is a circular baffle, and its outer edge extends into the baffle cover cap where the waterproof cover plate is placed.

[0009] The aforementioned waterproof structure for the swing shaft of the swing-type multi-wire cutting machine includes a rubber lip seal and a drum-type rubber oil seal.

[0010] This invention provides a waterproof structure for the oscillating shaft of a diamond wire multi-wire cutting machine. To address the harsh water mist environment inside the cutting chamber of the machine, it provides comprehensive protection for the oscillating shaft and bearings. It employs a combination of sealing rings, rubber oil seals, and a labyrinth-type waterproof component. The labyrinth-type waterproof component blocks or extends the path of water mist into the oscillating shaft, while simultaneously causing some water mist inside the cutting chamber to condense on the sidewall of the waterproof component and flow towards the cutting fluid recovery system. The sealing rings and rubber oil seals further prevent water mist from entering the bearing, thus extending the service life of the oscillating bearing and improving the cutting quality of the workpiece.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Diamond wire cutting machines use diamond particles bonded to cutting wires to create diamond wire. In their wire feeding system, the diamond wire is wound around a grooved wheel according to the cutting process requirements, forming a parallel cutting wire mesh. During operation, the grooved wheel drives the cutting wire in a reciprocating motion to cut the workpiece. Simultaneously, coolant is sprayed to cool the cutting wire and remove debris and impurities from the cut. (See Figure 1.) Figure 2The worktable oscillating multi-wire cutting machine uses an oscillating body 3 on the worktable to rotate around the oscillating shaft 2, causing the workpiece to oscillate left and right, making the workpiece contact the cutting wire mesh. At the same time, the worktable is driven downward by the lifting mechanism to feed the workpiece. During the operation of the worktable oscillating multi-wire cutting machine using diamond wire as the cutting wire, it is also necessary to spray coolant to cool the cutting wire and remove debris and impurities from the workpiece cut. This will generate a thick water mist in the cutting chamber, making the waterproofing of the oscillating shaft an important factor affecting the service life of the bearings, and also affecting the quality of the cut products.

[0032] See Figure 2 , Figure 3 , Figure 4 The swing body 3 of the worktable oscillating multi-wire cutting machine is an inverted U-shaped frame structure. The workpiece is clamped between the two vertical walls of the U-shaped frame. The swing shaft 2 is located at the bottom of the swing body 3 and includes two parts: a transmission-side swing shaft 2-1 and a transmission-side swing shaft 2-2. The transmission-side swing shaft 2-1 is the driving shaft and is connected to the swing drive mechanism. A swing bearing 4 is installed between the transmission-side swing shaft 2-1 and the shaft hole of the worktable frame 1 of the oscillating multi-wire cutting machine, and an inner bearing pressure cover 7 is provided on the inner side of the worktable frame 1 of the oscillating multi-wire cutting machine. The operating-side swing shaft 2-2 is the driven shaft. A swing bearing 4 is installed between the operating-side swing shaft 2-2 and the shaft hole of the worktable frame 1 of the oscillating multi-wire cutting machine, and an inner bearing pressure cover 7 is provided on the inner side of the worktable frame 1 of the oscillating multi-wire cutting machine. An expansion sleeve is installed between the operating-side swing shaft 2-2 and the shaft hole of the swing body 3, and an expansion sleeve pressure cover 9 is provided on the outer side of the swing body 3. The central axes of the transmission-side swing shaft 2-1 and the operating-side swing shaft 2-2 coincide.

[0033] See Figure 3 , Figure 4 This utility model provides a waterproof structure for the swing shaft of a swing-type multi-wire cutting machine, which includes a sealing ring 5, a rubber oil seal 8, and a labyrinth-type waterproof component 6. The sealing ring 5 is fitted onto the transmission-side swing shaft 2-1 and the operation-side swing shaft 2-2 of the swing worktable and is embedded in the sealing groove of the bearing inner pressure cover 7. The rubber oil seal 8 is fitted onto the inner end of the operation-side swing shaft 2-2 of the swing worktable and is embedded between the expansion sleeve pressure cover 9 of the operation-side swing shaft 2-2 and the operation-side swing shaft 2-2. The labyrinth-type waterproof component 6 is fitted onto the outside of the swing shaft 2 and consists of a waterproof cover plate 6-1 and a waterproof baffle plate 6-2. The waterproof cover plate 6-1 is fixed to the worktable frame 1 of the swing-type multi-wire cutting machine, and the waterproof baffle plate 6-2 is fixed to the swing body 3 of the worktable. The waterproof baffle plate 6-1 and the waterproof cover plate 6-2 cooperate to form a labyrinth-type water mist passage channel.

[0034] See Figure 5 , Figure 6 , Figure 7 , Figure 8 The waterproof structure of the swing shaft of the swing-type multi-wire cutting machine described in this utility model includes a labyrinth-type waterproof component 6. The waterproof cover plate 6-1 is provided with a swing shaft through hole 6-1-1. A flanged baffle cap 6-1-2 with a bottom opening is provided around the periphery of the waterproof cover plate 6-1. The upper part of the baffle cap 6-1-2 is a semi-circular annular groove that opens inward, and the lower part is a vertical groove arranged symmetrically on the left and right. The semi-circular annular groove connects with the two vertical grooves on the left and right. The waterproof baffle 6-2 is an annular baffle, and its outer edge extends into the baffle cap 6-1-2 where the waterproof cover plate is placed. The baffle cap 6-1-2 does not contact the baffle 6-2, leaving a gap between them. A labyrinth-type water mist passage is formed through the gap between them.

[0035] See Figures 1 to 8 This utility model provides a waterproof structure for the oscillating shaft of a diamond wire multi-wire cutting machine. To cope with the harsh water mist environment inside the cutting chamber of the diamond wire multi-wire cutting machine, it provides all-round protection for the oscillating shaft 2 and the oscillating bearing 4. It adopts a structure with a sealing ring 5, a rubber oil seal 8, and a labyrinth-type waterproof component 6. The labyrinth-type waterproof component 6 can prevent water mist from entering the oscillating shaft 2 from above, and the labyrinth-type water mist passage channel extends the path of water mist entering the oscillating shaft 2 from below. At the same time, some water mist in the cutting chamber condenses on the side wall of the waterproof component and flows to the cutting fluid recovery system. This utility model further prevents water mist from entering the interior of the oscillating bearing 4 through the sealing ring 5 and the rubber oil seal 8.
