Description

Technical Field

[0001] This utility model relates to the field of workpiece quenching and cooling technology, and in particular to a workpiece quenching and cooling device. Background Technology

[0002] In the processing and production of carbon steel drive shafts on machine tools, the carbon steel workpieces are usually heated to a certain appropriate temperature and held for a period of time, and then immersed in a cold water tank to cool them down quickly.

[0003] According to the search, the Chinese patent "A Cooling Equipment for Quenching Workpieces" authorized announcement number "CN215560469U" uses a cooling water tank and a water pump to work together to spray the workpiece located in the cooling tank to cool it down. The return pipe facilitates the return of the cooling water inside the cooling tank to the cooling water tank, avoiding unnecessary waste of water resources.

[0004] In the aforementioned application, after the water in the cooling tank comes into contact with the workpiece, the water in the cooling tank will heat up. The heated water will then flow back into the cooling water tank, causing the water temperature stored in the cooling water tank to be too high, which in turn affects the quenching and cooling effect on the workpiece. Utility Model Content

[0005] Therefore, it is necessary to provide a workpiece quenching and cooling device to address the problem of the heated water flowing back into the cooling water tank, causing the temperature of the water stored in the cooling water tank to become too high.

[0006] The system includes: a cold water tank; and a cooling mechanism. The cooling mechanism includes a connecting pipe connected to the lower end of the inner wall of the cold water tank, the other end of which is connected to a heat exchanger. One end of the heat exchanger is connected to a water pump, and the other end of the water pump is connected to the inner wall of the cold water tank. A filter frame is installed inside the connecting pipe. Water is drawn from the cold water tank by the water pump and flows into the heat exchanger through the connecting pipe, thereby cooling the flowing water. The cooled water is then pumped back to the cold water tank, ensuring that the water in the cold water tank remains at a low temperature, thus guaranteeing the effective quenching and cooling of the workpiece. The filter screen filters the water flowing into the heat exchanger, preventing metallic impurities from flowing into the heat exchanger and avoiding the risk of blockage.

[0007] In one embodiment, a plug is rotatably connected to the inner wall of the connecting pipe. The plug seals the inside of the connecting pipe, thereby preventing water from flowing from the cold water tank into the connecting pipe. This facilitates the disassembly and cleaning of the filter frame, ensuring the amount of water flowing from the connecting pipe into the heat exchanger and guaranteeing the cooling effect of the heat exchanger on the water in the cold water tank.

[0008] In one embodiment, a first screw is threaded to the upper end of the inner wall of the plug, and the surface of the first screw is threaded to the upper end of the inner wall of the connecting pipe.

[0009] In one embodiment, two rubber rings are fixedly connected to the upper inner wall of the connecting pipe, and the surface of the filter frame is slidably connected to the inner wall of the rubber rings. The rubber rings seal the connection between the filter frame and the connecting pipe, thereby preventing water from overflowing from the connecting pipe through the filter frame.

[0010] In one embodiment, guide rods are fixedly connected to both sides of the filter frame, and the surfaces of the guide rods are slidably connected to the upper end of the inner wall of the connecting pipe. The guide rods provide precise guidance for the filter frame to slide into the connecting pipe.

[0011] In one embodiment, a limiting block is slidably connected to the upper surface of the connecting pipe, and the surface of the limiting block is engaged with the upper end of the inner wall of the guide rod.

[0012] In one embodiment, the inner wall of the limiting block is threadedly connected to a second screw, and the surface of the second screw is threadedly connected to the upper end of the inner wall of the connecting pipe.

[0013] In one embodiment, two stop bars are fixedly connected to the upper surface of the connecting pipe.

[0014] Beneficial effects

[0015] 1. Water is pumped from the cold water tank and flows into the heat exchanger through connecting pipes, thereby cooling the flowing water. The cooled water is then pumped back to the cold water tank, ensuring that the water in the cold water tank remains at a low temperature, thus guaranteeing the quenching and cooling effect on the workpiece. The water flowing into the heat exchanger is filtered through a filter screen, preventing metal impurities in the water from flowing into the heat exchanger and avoiding the risk of blockage.

[0016] 2. The plug can seal the inside of the connecting pipe, thereby preventing water from flowing from the cold water tank into the connecting pipe. This makes it easier to disassemble and clean the filter frame, thus ensuring the amount of water flowing from the connecting pipe into the heat exchanger and ensuring the cooling effect of the heat exchanger on the water in the cold water tank.

[0029] The following is combined with Figures 1-4 This invention describes a workpiece quenching and cooling treatment device.

[0030] In one embodiment, a workpiece quenching and cooling treatment device includes: a cold water tank 100; a cooling mechanism 200, the cooling mechanism 200 including a connecting pipe 201 connected to the lower end of the inner wall of the cold water tank 100, the other end of the connecting pipe 201 being connected to a heat exchanger 202, one end of the heat exchanger 202 being connected to a water pump 203, the other end of the water pump 203 being connected to the inner wall of the cold water tank 100, and a filter frame 204 being provided inside the connecting pipe 201.

[0031] The inner wall of the filter frame 204 is fixedly connected with a first filter screen and a second filter screen. The mesh size of the first filter screen is larger than that of the second filter screen. The first filter screen is used to intercept large impurities in the water, and the second filter screen is used to intercept small impurities in the water. One side of the cold water tank 100 is connected to an inlet pipe, and the other side of the cold water tank 100 is connected to an outlet pipe. The inlet pipe and outlet pipe are connected to the corresponding pipes by flanges. The inlet pipe and outlet pipe of the cooling medium on the heat exchanger 202 are connected to the corresponding pipes by flanges, so that the corresponding pipes continuously provide coolant to the heat exchanger 202, and the heated coolant is transported to the corresponding equipment for cooling.

[0032] When the carbon steel workpiece of the drive shaft needs to be quenched and cooled, a certain amount of cold water is injected into the cold water tank 100, the workpiece is placed in the storage frame, and the storage frame is lifted into the cold water in the cold water tank 100 by an electric hoist or other lifting equipment, so that the cold water absorbs the heat on the surface of the workpiece. After the workpiece is cooled in the cold water for a period of time, the workpiece is lifted out.

[0033] The heat exchanger 202 is composed of heat transfer plates, sealing gaskets, pressure plates, clamping bolts, and frames.

[0034] Heat exchanger 202 is based on the principle of indirect heat exchange, in which the hot and cold media flow in the flow channels formed by adjacent plates and exchange heat through the plates. The heat of the hot medium is transferred to the cold medium through the plates, thereby lowering the temperature of the hot medium and raising the temperature of the cold medium.

[0035] In this embodiment, the workpiece is in the cold water tank 100. The water pump 203 and heat exchanger 202 are manually turned on, so that the water in the cold water tank 100 is filtered through the filter frame 204 in the connecting pipe 201 and flows into the heat medium inlet of the heat exchanger 202. The coolant flows into the cold medium inlet of the heat exchanger 202. The water and coolant flow in their respective channels. Since the plates on the heat exchanger 202 have good thermal conductivity, the heat of the water is transferred to the coolant through the plates. During the flow, the water continuously releases heat and the temperature gradually decreases. The cooled water flows back into the cold water tank 100 through the water pump 203.

[0036] like Figure 4 As shown, a plug 205 is rotatably connected to the inner wall of the connecting pipe 201. A first screw 210 is threadedly connected to the upper end of the inner wall of the plug 205. The surface of the first screw 210 is threaded to the upper end of the inner wall of the connecting pipe 201. Two stop rods 211 are fixedly connected to the upper surface of the connecting pipe 201. A silicone ring is embedded in the surface of the plug 205. The plug 205 is a ductile iron component.

[0037] like Figure 3 As shown, two rubber rings 207 are fixedly connected to the upper end of the inner wall of the connecting pipe 201. The surface of the filter frame 204 is slidably connected to the inner wall of the rubber rings 207. Guide rods 206 are fixedly connected to both sides of the filter frame 204. The surface of the guide rods 206 is slidably connected to the upper end of the inner wall of the connecting pipe 201. A limiting block 208 is slidably connected to the upper end of the surface of the connecting pipe 201. The surface of the limiting block 208 is engaged with the upper end of the inner wall of the guide rods 206. A second screw 209 is threadedly connected to the inner wall of the limiting block 208. The surface of the second screw 209 is threadedly connected to the upper end of the inner wall of the connecting pipe 201. Both the first screw 210 and the second screw 209 are galvanized steel components.

[0038] In this embodiment, when the filter frame 204 needs to be cleaned, the first screw 210 is rotated away from the connecting pipe 201, and the rotating block 205 abuts against one of the stop rods 211. The first screw 210 inside the block 205 is rotated so that the first screw 210 is threaded into the connecting pipe 201, thus sealing the inside of the connecting pipe 201 and preventing water from flowing from the cold water pool 100 to the surface of the filter frame 204. The second screw 209 is rotated away from the connecting pipe 201, and the limiting block 208 is pulled away from the guide rod 206, thus pulling the filter frame 204 away from the connecting pipe 201, and the filter frame 204 can be cleaned.

[0039] After cleaning, slide the guide rod 206 into the connecting pipe 201, so that the filter frame 204 can be accurately slid into the rubber ring 207 and the connecting pipe 201. Push the limiting block 208 to engage with the guide rod 206. Rotate the second screw 209 inside the limiting block 208 so that the second screw 209 is threaded into the connecting pipe 201. Rotate the first screw 210 away from the connecting pipe 201. Rotate the plug 205 to abut against another stop rod 211. Rotate the first screw 210 inside the plug 205 so that the first screw 210 is threaded into the connecting pipe 201, making the inside of the connecting pipe 201 open.

[0040] Working principle: Manually turn on the water pump 203 and heat exchanger 202 so that the water in the cold water pool 100 is filtered through the filter frame 204 in the connecting pipe 201 and flows into the heat exchanger 202. The coolant flowing in the heat exchanger 202 absorbs the heat of the water, so that the water temperature gradually decreases. The cooled water flows back into the cold water pool 100 through the water pump 203.

[0041] It should be noted that the cold water tank 100, heat exchanger 202, water pump 203 and filter frame 204 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the heat exchanger 202 and water pump 203 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
