Description

Technical Field

[0001] The utility model relates to the technical field of wire saws, and particularly relates to a wire saw with shaft cooling. Background Art

[0002] After being polished, marble is very beautiful and is mainly used for processing various profiles and plates, as the wall, floor, platform, and column of buildings, and is also often used as the material for commemorative buildings such as monuments, towers, and statues. Marble can also be carved into practical artworks such as arts and crafts, stationery, lamps, and utensils.

[0003] When cutting large pieces of marble, a saw is generally used for cutting. When using a wire saw for cutting, most of the existing wire saws use rollers to drive the diamond wire to rotate, thereby producing a cutting effect on the marble. During the cutting process, the rollers need to rotate at a high speed. It is found during use that when the rollers work for a long time, the bearings supporting the rollers will deform and jam due to the high temperature, resulting in a short service life of the bearings and requiring frequent maintenance and replacement. Therefore, this technical solution is proposed for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiency that the bearings have a short service life due to high temperature during the high-speed rotation of the rollers in the prior art, and to provide a wire saw with shaft cooling.

[0005] In order to achieve the above purpose, the embodiments of the utility model specifically adopt the following technical solutions: A wire saw with shaft cooling includes a horizontally arranged mounting frame. A lifting frame for placing the body to be cut is arranged at the bottom of the mounting frame. Four rollers for supporting the diamond wire are arranged at the upper part of the mounting frame. The rotating shafts at both ends of the rollers are connected to the mounting frame through bearing seats. The bearing seat includes a housing, and a cooling device is arranged inside the housing. The cooling device includes an oil inlet joint for connecting cooling oil arranged at the top of the housing, and a flow channel for oil outlet is arranged at the bottom of the housing.

[0006] Further, the rotating shaft passes through the bearing seat, and two groups of bearings are arranged at both ends of the bearing seat through which the rotating shaft penetrates for rotatably connecting with the bearing seat, and a plug plate is arranged outside the bearings.

[0007] Further, a spacer sleeve is arranged on the rotating shaft between the two groups of bearings. A copper sleeve is sleeved outside the spacer sleeve. Four through holes are arranged on the outer wall of the copper sleeve, and a cooling cavity is arranged between the copper sleeve and the spacer sleeve.

[0008] Further, convex ribs facing the spacer sleeve are arranged at both ends of the copper sleeve, and a gap is arranged between the convex ribs and the outer wall of the spacer sleeve.

[0009] Furthermore, the flow channel is arranged at the bottom of the shell, and the inlet of the flow channel is arranged in a ring shape between the blocking plate and the bearing.

[0010] Furthermore, the oil inlet joint and the outlet of the flow channel are connected to a pump station with a cooling function through a pipeline.

[0011] The beneficial effects of the embodiments of the utility model are as follows: a cooling device is used on the bearing seat connected to the roller and the mounting frame to cool the inside of the bearing seat, thereby reducing the temperature during use; a cooling cavity is formed between the copper sleeve and the spacer sleeve, and the shaft and the bearing are cooled by the flow of gear oil while maintaining stable rotation of the shaft, thereby preventing the bearing and the shaft from deforming or getting stuck when rotating at high speed; the cooled gear oil forms a stable oil pressure support inside the cooling cavity, thereby reducing the shaking of the shaft during rotation, ensuring the use effect, extending the service life, and reducing the failure rate.

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0018] See also Figures 1 to 4, an embodiment of the utility model discloses a wire saw with shaft cooling, which mainly consists of a mounting frame 1, a lifting frame 3, a cutting part, a base, an inspection platform 101 and auxiliary devices. The mounting frame 1 serves as the support frame of the entire device and is welded with high-strength steel to ensure a stable structure. When in use, a base can be set at the bottom of the mounting frame 1. The base can be a cement or metal base and can be selected for installation according to the usage environment. Multiple diversion grooves are opened on the upper surface of the base to guide out the coolant and residues during the cutting process, improving stability and usage effect.

[0019] The bottom of the mounting frame 1 is designed as an open frame, which is convenient for maintenance and observing the cutting process. Reinforcing ribs are provided at both the top and bottom to enhance the overall stiffness. When installing, ensure that the mounting frame 1 is installed horizontally. A horizontal mounting surface is provided on the upper part of the mounting frame 1 for installing cutting components such as rollers 2. A cutting part is provided on the upper part of the mounting frame 1 for cutting marble. The cutting part consists of four mutually parallel rollers 2. The installation positions of the rollers 2 are arranged in a rectangular layout. The two lower rollers 2 are arranged inside the inspection platform 101 to improve the compactness of the device. Multiple precisely machined grooves are provided on the surface of the rollers 2 to accommodate and guide the diamond wire for cutting. By accommodating the diamond wire in multiple grooves on the side of the rollers 2, the effect of simultaneous cutting on multiple working surfaces is formed. The distance between the upper roller 2 and the lower roller 2 is relatively large to prevent the upper diamond wire from affecting the cutting effect after the marble is cut by the lower diamond wire, ensuring safe use and improving production quality. A protective plate 103 is provided on the side of the roller 2, and the protective plate 103 can be disassembled to prevent the flying of debris generated during the cutting process from hurting people. At the same time, it protects the roller 2 from external interference, ensuring production safety. Standing on the inspection platform 101 also increases the operation space. The staircase 102 on one side facilitates the up and down movement of personnel. And the entire mounting frame 1 and inspection platform 101 can select different sizes according to different marble production specifications. Driving motors 201 are installed on all four rollers 2 to provide sufficient power for the diamond wire, ensuring the production effect.

[0020] The two ends of the roller 2 are mounted on the mounting frame 1 through the bearing 205 seat 202, one end of which is connected to the driving motor 201, and the high-speed rotation of the roller 2 is achieved through the bearing 205 seat 202 to ensure the stability of use, wherein the bearing 205 seat 202 includes a shell 203, and a cooling system for cooling the bearing 205 and the rotating shaft 204 at both ends of the roller 2 is arranged inside the shell 203, and the rotating shaft 204 passes through the bearing 205 seat 202, and the rotating shaft 204 is provided with two sets of bearings 205 at both ends of the bearing 205 seat 202, which are rotatably connected to the bearing 205 seat 202, and the bearing 205 A blocking plate 206 is arranged on the outer side of the bearing 205, a spacer 208 is arranged on the rotating shaft 204 between the two sets of bearings 205, a copper sleeve 207 is sleeved on the outer side of the spacer 208, a cooling chamber is arranged between the copper sleeve 207 and the spacer 208, convex ridges facing the spacer 208 are arranged at both ends of the copper sleeve 207, a gap is left between the convex ridges and the outer wall of the spacer 208, four through holes are arranged on the outer wall of the copper sleeve 207, an oil inlet joint 2031 connected to the pump station is arranged on the top of the bearing 205 seat 202, a flow channel 209 is arranged at the bottom of the bearing 205 seat 202, and the flow channel 209 The inlet is arranged between the plugging plate 206 and the bearing 205, and the outlet of the flow channel 209 is connected to the cooling box of the pump station through a pipeline. When the roller 2 rotates at a high speed, high temperature is generated between the rotating shaft 204 of the roller 2 and the bearing 205 seat 202. The gear oil cooled by the cooling box in the pump station passes through the oil inlet joint 2031 on the top of the bearing 205 seat 202 and abuts against the outer wall of the copper sleeve 207, and enters the cooling chamber through the four through holes on the outer side of the copper sleeve 207. Under the action of oil pressure, the copper sleeve 207 is pushed outward, and the cooled gear oil forms a stable oil pressure support in the cooling chamber. The gear oil flows to the bearing 205 through the gap between the copper sleeve 207 and the spacer sleeve 208. The plugging plate 206 prevents the gear oil from leaking out. The gear oil seeping out of the bearing 205 flows into the flow channel 209 and flows to the bottom of the bearing 205 seat 202 under the action of gravity and pressure. A circulation is formed through the pipeline to complete the cooling of the shaft 204 and the bearing 205, and prevent the bearing 205 and the shaft 204 from being deformed or stuck when rotating at high speed, thereby ensuring the use effect, extending the service life and reducing the failure rate.

[0021] The lifting frame 3 is located at the bottom of the mounting frame 1, and is used to carry and stabilize the marble body to be cut. The lifting frame 3 is driven by four screw rods 301 vertically arranged at the lower part of the mounting frame 1. The motor's brake system prevents the lifting frame 3 from sliding uncontrollably. Each screw rod 301 is respectively connected to the four corners of the lifting frame 3 to ensure that the lifting process is smooth and without shaking. The four screw rods 301 realize the synchronous lifting control of the lifting frame 3, ensuring that the stone remains horizontal and stable during the cutting process, improving the cutting efficiency and accuracy of hard materials such as marble, and reducing production costs and waste of raw materials.

[0022] During the use process, place the marble body to be cut on the lifting frame 3, adjust the height of the lifting frame 3 to keep an appropriate distance between the stone surface and the diamond wire on the roller 2, start the driving motor 201 to make the roller 2 start to rotate. The diamond wire is tensioned and rotated at high speed through the groove on the roller 2. As the lifting frame 3 slowly rises, the diamond wire gradually cuts into the interior of the stone, greatly improving the cutting efficiency and accuracy, reducing the waste of raw materials. The operator can monitor the cutting process in real time through the inspection platform 101 and observe the quality of the stone cutting surface. If necessary, the speed of the lifting frame 3 or the rotation speed of the roller 2 can be adjusted in time to ensure the cutting effect. When the stone is completely cut into the required shape, turn off the driving motor 201 to stop the rotation of the roller 2. Take out the cut stone through the lifting frame 3 for subsequent processing.
