Description

Technical Field

[0001] The present invention relates to the field of wire drawing motors, and mainly relates to an integrated water tray type wire drawing motor structure. Background Art

[0002] Chinese Patent CN208495401U discloses a modular water tray of a direct-connected high-efficiency wire drawing machine, including a water tray. A reel shaft is rotatably arranged in the inner hole of the water tray. The lower end of the reel shaft is rotatably supported in the lower hole of the water tray through a first bearing and is fixedly pressed and fixed through a lower gland; the part where the reel shaft extends out of the water tray is rotatably supported through a second bearing. The lower end of the second bearing is limited by an oil baffle ring, and the upper end of the second bearing is limited by an upper gland fixedly connected to the upper end face of the water tray; the upper part of the reel shaft is fixedly connected with a reel, and the lower end of the outer ring of the reel is matched with the upper end of the outer ring of the water tray. The deficiencies of its structure are as follows: 1. The water tray has a single function and is mainly used for storing water. 2. The water cooling structure of the reel (steel sleeve) uses water pipes connected to each other, which results in many water pipes inside the wire drawing machine and great installation difficulty, inconvenient later maintenance and high cost. 3. The two bearings on the reel shaft are very close to each other, and the bearings bear a very large force, so only a thicker reel shaft can be selected. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies existing in the prior art, and to provide an integrated water tray type wire drawing motor structure with high efficiency, low cost and no water pipes inside the steel sleeve.

[0004] The purpose of the present invention is achieved by the following technical solutions. An integrated water tray type wire drawing motor structure includes a motor body, a main shaft, a water tray and a steel sleeve. The lower end face of the water tray is fixedly connected to the end face of the motor body as a motor end cover. A water retaining ring A is fixedly connected to the upper end face of the water tray and is arranged inside the steel sleeve. There are gaps between the water retaining ring A and the side wall and the top wall of the steel sleeve; the main shaft of the motor body is rotatably arranged in the inner hole of the water tray and is fixedly connected to the steel sleeve; an inlet and an outlet are arranged on the lower water tray between the water retaining ring A and the steel sleeve. The inlet is connected to the water receiving cavity inside the water retaining ring A through the gap to form an overflow type water cooling structure; the water receiving cavity is connected to the outlet.

[0005] Furthermore, a boss with an inner hole is provided on the top wall of the steel sleeve, and a water retaining ring B is fixedly connected to the lower end face of the boss. A pressing plate is arranged on the central convex structure of the water tray, and the water retaining ring B covers the outer surface of the pressing plate.

[0006] Furthermore, a bearing A is arranged at the cooperation position between the upper end of the main shaft and the inner hole of the water tray, and a bearing B is arranged at the lower end of the main shaft for cooperation with it.

[0007] Furthermore, an air vent, a drain port and an oil filling port are also arranged on the lower water tray between the water retaining ring A and the steel sleeve. Among them, the drain port is connected to the water receiving cavity, the oil filling port is used to lubricate the bearing A, and the air vent is used to balance the internal and external air pressures.

Detailed Description of the Embodiment

[0021] The present invention will be described in detail below in conjunction with the drawings and embodiments:

[0022] As Figure 1 shown, the present invention provides an integrated water tray type wire drawing motor structure, which is a motor structure with a water tray as a fixed support member, including a motor body 11, a main shaft 5, a water tray 1 and a steel sleeve 2. The main shaft 5 of the motor body 11 is rotatably arranged in the inner hole of the water tray 1 and fixedly connected to the steel sleeve 2. The lower end surface of the water tray 1 is fixedly connected to the end surface of the motor body 11 as a motor end cover. The upper end surface of the water tray 1 is fixedly connected with a water retaining ring A3 by screws and is arranged inside the steel sleeve 2. There are gaps 15 between the water retaining ring A3 and the side wall and the top wall of the steel sleeve 2. The water tray 1 is both a water receiving device, a motor end cover, and a support member for the water retaining ring A3.

[0023] As Figure 2 shown, there is a circle of through holes around the water tray 1, that is, an inlet 9, an outlet 10, a ventilation port 12, a drain port 13 and an oil injection port 14 are provided on the lower water tray 1 between the water retaining ring A3 and the steel sleeve 2. Among them, the inlet 9 and the outlet 10 are used to connect the inlet and outlet of the cooling water. The drain port 13 is communicated with the water receiving cavity 18, and the leakage (allowed) inside the water tray 1 is discharged from the drain hole 13; the oil injected through the oil injection port 14 is used to lubricate the bearing A6. The ventilation port 12 is connected to a trachea (if needed) to balance the internal and external air pressures, and it is determined whether it needs to be opened according to customer requirements. In this embodiment, 4 inlets 9 and 8 outlets 10 are adopted to fully ensure the normal circulation of water. The water pipe is connected to the inlet of the water tray 1, and there is no water pipe inside the steel sleeve 2. The drain hole 13 is used to discharge the water leakage inside the water retaining ring A3, and this leakage is within the allowed range and does not affect the normal operation of the motor and the normal operation of the water circulation.

[0024] Overflow type water cooling structure: The cooling water enters from the inlet 9 and flows upward through the gaps 15 between the side wall and the top wall of the water retaining ring A3 and the steel sleeve 2. The water cools the heat transferred from the steel sleeve 2 until it reaches the upper edge of the water retaining ring A3 and flows down along the inner ring of the water retaining ring A3, enters the water receiving cavity 18 of the water tray 1, and flows out from the outlet 10 and the drain port 13. The water flow direction is as Figure 2 shown by the arrow. The present invention adopts an overflow type water cooling structure, which changes the water flow direction, cools the steel sleeve in the way of rising and overflowing the water level, enables the steel sleeve to be cooled in a timely and sufficient manner, and the circulation relies on the natural rise and overflow of water. High-efficiency cooling effect can be achieved without connecting a water pipe inside the steel sleeve.

[0025] A boss 2-1 with an inner hole is provided on the top wall of the steel sleeve 2. A pressure plate 19 is provided on the central convex structure of the water tray 1, and the water retaining ring B7 covers the outer surface of the pressure plate 19.

[0026] At the upper end of the main shaft 5 where it mates with the inner hole of the water tray 1, there is a bearing A6 (cylindrical roller bearing NJ2220). At the lower end of the main shaft 5, there is a bearing B8 (tapered roller bearing 30220) that mates with it. The distance between the two bearings becomes larger, the bearings bear the force evenly, and they have sufficient bearing capacity. The main shaft 5 is directly connected to the steel sleeve 2, directly driving the steel sleeve 2 for wire drawing. There is no extra loss, which is the most efficient operation connection method and the lowest maintenance cost.

[0027] As Figure 3 shown, the steel sleeve 2 is a rotating part, the water retaining ring A3 and the water tray 1 are fixed parts, and there are gaps between the three. The silica gel pad 4 is fixed in the groove inside the steel sleeve 2 by screws. There is a gap between the steel sleeve 2 and the water retaining ring A3, and a circle of silica gel pad 4 is arranged above it. During specific installation, the silica gel pad 4 needs to be fixed in the groove inside the steel sleeve 2 in advance and installed together with the steel sleeve 2. After installation, it should be flush with the bottom surface of the water retaining ring A3 to prevent a large amount of cooling water from flowing down (allowing a small amount of leakage, and there is a drain port on the lower water tray), causing the liquid level to rise.

[0028] The mating part between the steel sleeve 2 and the main shaft 5 adopts a tapered surface mating connection to form a direct connection structure. The steel sleeve 2 and the main shaft 5 can be fixed to rotate together through key connection. The greatest advantage of the tapered surface mating is that it can center, eliminate gaps, and is convenient for disassembly and assembly.

[0029] On the motor body 11, there are a motor cooling water outlet 16 and a motor cooling water inlet 17. The motor body 11 is vertically installed, and the motor cooling water inlet 17 is arranged below the motor cooling water outlet 16 to form a cooling cycle. The motor cooling water inlet 17 must be below to prevent air from being unable to escape and causing the motor to heat up.

[0030] In the present invention, an oil seal needs to be set at the mating part of the main shaft 5, which can largely avoid problems such as the leakage of lubricating grease and the entry of foreign objects and garbage into the bearing, causing damage to the bearing.

[0031] Working process: When the main shaft 5 drives the steel sleeve 2 to rotate, after the drawn wire winds around the steel sleeve 2 for multiple turns, the heat generated by the drawn wire is transferred to the steel sleeve 2. The heat of the wire has a great impact on the subsequent drawing. It is necessary to cool the wire, that is, to cool the steel sleeve 2. Continuously add water to the water inlets 9 around the water tray 1. The inner wall of the steel sleeve 2 directly contacts the rising water for heat transfer. When the height of the water exceeds the height of the water retaining ring A3, the water overflows into the water receiving cavity 18 of the water tray 1 and then flows out from the eight water outlets below the water tray 1.

[0032] It can be understood that for those skilled in the art, any equivalent replacement or change to the technical solution and inventive concept of the present invention should fall within the protection scope of the appended claims of the present invention.
