Description

Technical Field

[0001] This utility model relates to the field of horizontal long bar quenching technology, specifically a water spray curtain water blocking device. Background Technology

[0002] In industrial fields such as automotive drive shafts, engineering machinery piston rods, and machine tool spindles, a large number of long bar parts need to be improved in terms of surface hardness and wear resistance through horizontal long bar induction hardening process. In this process, the long bar workpiece is continuously fed horizontally along the conveyor roller, and passes through the induction coil (which heats the workpiece surface by passing high-frequency current) and the water spray cooling zone (which cools down quickly by high-pressure water flow to complete the hardening), and finally forms a hardened layer that meets the requirements.

[0003] When a workpiece passes through the annular water spray ring, the water jet hits the workpiece surface and splashes backward, with some water adhering to the surface and flowing backward, forming backflow. This reduces the heating temperature and severely affects the quenching quality. To address this issue, we designed and manufactured a water spray curtain blocking device that completely intercepts the backflow at the front of the spray, preventing it from affecting the workpiece heating temperature and effectively controlling the quenching quality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a water curtain blocking device that can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a water curtain blocking device, including a mounting plate and a workpiece located inside the mounting plate. An outer ring is fixedly installed at one end of the mounting plate, and an inner ring is provided on the side of the outer ring away from the mounting plate. A water blocking ring is fixedly installed at the end of the inner ring away from the outer ring. A female stop is fixedly installed at the end of the outer ring close to the inner ring, and a male stop is fixedly installed at the end of the inner ring close to the outer ring. A water inlet is opened on the outer side of the outer ring, and a buffer stop ring is provided on the inner side of the water inlet.

[0006] Preferably, the female stop and the male stop are adapted to each other, and the male stop can be inserted into the female stop.

[0007] The above technical solution, through the matching of the female stop and the male stop, and the male stop being able to snap into the female stop, enables the rapid positioning and installation of the outer ring and the inner ring without the need for additional calibration, reducing the difficulty of installation. Furthermore, the stop fit structure can seal the connection gap between the outer ring and the inner ring, preventing water leakage from the connection point and ensuring the overall sealing of the device.

[0008] Preferably, the outer diameter of the inner ring is smaller than the inner diameter of the outer ring, and a flow channel is formed between the outer ring and the inner ring.

[0009] By using the above technical solution, a flow channel is formed between the outer and inner rings, allowing water to be injected through the inlet and sprayed out through the flow channel to form a water curtain, which blocks the backflow when it hits the surface of the workpiece.

[0010] Preferably, the cross-section of the flow channel is an "annular" structure, and the end of the flow channel near the mounting plate is provided with an incline.

[0011] Through the above technical solution, by setting an angle at one end of the flow channel near the mounting plate, different angles of water curtain spray can be obtained by designing and manufacturing different angles, and water curtains of different thicknesses can be obtained by changing the gap between the inner and outer rings.

[0012] Preferably, the water inlet is provided in two identical sets, and the two sets of water inlets are symmetrically distributed on the outer surface of the outer ring.

[0013] By using the above technical solution and setting up two sets of symmetrically distributed inlets, water can enter the flow channel from both sides simultaneously, avoiding uneven water pressure in the flow channel caused by water entering from only one side.

[0014] Preferably, the water-blocking ring has a tapered cross-section at the end near the mounting plate, and a drain outlet is provided at the bottom of the water-blocking ring.

[0015] Through the above technical solution, by setting up a water-blocking ring, the small amount of unblocked backflow is blocked again. The small amount of unblocked backflow from the annular water curtain impacts the conical surface of the water-blocking ring and flows downward along the conical surface into the drain outlet and into the equipment's water collection tank.

[0016] Compared with the prior art, the present invention provides a water curtain blocking device, which has the following beneficial effects: 1. This water spray curtain water blocking device, after the water entering from the inlet impacts the buffer ring, overflows into the flow channel and sprays out along the set slope and thickness to form a conical ring water curtain. When it hits the surface of the workpiece, it blocks the backflow. In conjunction with the water blocking ring, it blocks the small amount of backflow that is not blocked again. The small amount of backflow that is not blocked by the ring water curtain impacts the conical surface of the water blocking ring and flows down along the conical surface into the drain outlet and into the equipment water collection tank. 2. The water curtain blocking device has a water inlet on each side of the outer ring and a buffer ring in the middle. The water entering from the water inlet impacts the buffer ring and overflows into the flow channel, so that the water entering from the water inlet is buffered and then enters the water nozzle evenly to form a uniform water curtain.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: As Figure 1-4 As shown, the present invention provides a water curtain blocking device, including a mounting plate 1 and a workpiece 11 located inside the mounting plate 1. An outer ring 2 is fixedly installed at one end of the mounting plate 1. An inner ring 3 is provided on the side of the outer ring 2 away from the mounting plate 1. A water blocking ring 4 is fixedly installed on the side of the inner ring 3 away from the outer ring 2. A female stop 6 is fixedly installed on the side of the outer ring 2 close to the inner ring 3. A male stop 7 is fixedly installed on the side of the inner ring 3 close to the outer ring 2. A water inlet 9 is opened on the outer side of the outer ring 2. A buffer stop ring 10 is provided on the inner side of the water inlet 9.

[0021] Specifically, the female stop 6 and the male stop 7 are compatible, with the male stop 7 snapping into the female stop 6. The advantage is that the compatibility of the female stop 6 and the male stop 7, and the snapping of the male stop 7 into the female stop 6, allows for quick positioning and installation of the outer ring 2 and the inner ring 3 without additional calibration, reducing installation difficulty. Furthermore, the stop fit structure seals the connection gap between the outer ring 2 and the inner ring 3, preventing water leakage at the connection point and ensuring the overall sealing of the device.

[0022] Specifically, the outer diameter of the inner ring 3 is smaller than the inner diameter of the outer ring 2, and a flow channel 8 is formed between the outer ring 2 and the inner ring 3. The advantage is that by forming a flow channel 8 between the outer ring 2 and the inner ring 3, water can be poured in through the inlet 9 and sprayed out through the flow channel 8 to form a water curtain, which blocks the backflow when it hits the surface of the workpiece.

[0023] Specifically, the cross-section of the flow channel 8 is an annular structure, and the end of the flow channel 8 near the mounting plate 1 is sloped. The advantage is that by setting the end of the flow channel 8 near the mounting plate 1 to have a slope, different slopes of water curtain can be obtained by designing and manufacturing different slopes, and water curtains of different thicknesses can be obtained by changing the gap between the inner ring 3 and the outer ring 2.

[0024] Example 2: Figure 2-4 As shown, this is an improvement on the previous embodiment.

[0025] Specifically, there are two identical sets of inlets 9, which are symmetrically distributed on the outer surface of the outer ring 2. The advantage is that by setting two symmetrically distributed sets of inlets 9, water can enter the flow channel 8 from both sides simultaneously, avoiding uneven water pressure in the flow channel 8 caused by water entering from one side.

[0026] Specifically, the end of the water-blocking ring 4 closest to the mounting plate 1 has a conical cross-section, and a drain outlet 5 is provided at the bottom of the water-blocking ring 4. The advantage is that by setting the water-blocking ring 4, the small amount of unblocked backflow is blocked again, and the small amount of unblocked backflow of the annular water curtain impacts the conical surface of the water-blocking ring 4 backward, and flows downward along the conical surface into the drain outlet 5 and into the equipment water collection tank.

[0027] Working principle: In use, the outer ring 2 is first fixedly installed on the mounting plate 1. Then, the female stop 6 and the male stop 7 are matched, and the male stop 7 can be inserted into the female stop 6, which can realize the quick positioning and installation of the outer ring 2 and the inner ring 3 without additional calibration, reducing the installation difficulty. The stop fit structure can seal the connection gap between the outer ring 2 and the inner ring 3, preventing water leakage from the connection point and ensuring the overall sealing of the device. The outer diameter of the inner ring 3 is smaller than the inner diameter of the outer ring 2, forming a flow channel 8 between the outer ring 2 and the inner ring 3. The end of the flow channel 8 near the mounting plate 1 is provided with an incline. Different inclines can be designed and manufactured to obtain different spray angles. The water curtain can be made of different thicknesses by changing the gap between the inner ring 3 and the outer ring 2. There is a water inlet 9 on each side of the outer ring 2 and a buffer baffle 10 in the middle. The water entering from the water inlet 9 impacts the buffer baffle 10 and overflows into the flow channel 8. It sprays out along the set slope and thickness to form a conical ring water curtain. When it hits the surface of the workpiece, it blocks the backflow. Then, a water baffle 4 is fixed at the rear end of the inner ring 3, which blocks the small amount of backflow that is not blocked. The small amount of backflow that is not blocked by the ring water curtain impacts the conical surface of the water baffle 4 and flows down the conical surface into the drain outlet 5 and into the equipment water collection tank.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
