Description

Technical Field

[0001] This utility model relates to the field of alloy hammerhead quenching technology, specifically to a continuous water-cooled quenching device for the processing of alloy hammerheads in crushers. Background Technology

[0002] Quenching is a crucial step in metal heat treatment. Its core function is to change the internal structure of the material through "rapid cooling," thereby endowing the workpiece with specific mechanical properties (such as hardness, wear resistance, and strength). In order to make the alloy hammerhead have high hardness, low-temperature oil quenching is generally used to ensure rapid cooling and obtain martensitic structure.

[0003] The existing Chinese utility model patent with publication number CN217781219U discloses an alloy hammerhead quenching device, including a quenching liquid tank and a quenching groove. A workpiece tray is suspended inside the quenching groove, and a quenching liquid delivery pipe is located below the workpiece tray inside the quenching groove. An overflow port is located high on the side of the quenching groove, with its overall height higher than the top surface of the workpiece tray. The overflow port and the quenching liquid delivery pipe are connected to the quenching liquid tank. This utility model can improve the performance of alloy hammerheads after quenching, enabling the alloy hammerheads to meet the requirements of high impact force conditions.

[0004] The aforementioned quenching device cannot cool the quenching fluid. During continuous quenching, the temperature of the quenching fluid will rise, affecting the cooling rate. At the same time, during the quenching process, the oxide scale on the surface of the hammer will peel off during cooling, forming fine particles suspended in the quenching fluid. Impurities will deposit on the surface of the workpiece, which may result in rough surface, rust, or black spots after quenching, affecting subsequent processing. Utility Model Content

[0009] Preferably, the conveying assembly includes a quenching tank fixedly installed above the support frame, connecting frames fixedly installed at both ends of the quenching tank, a limiting shaft interlaced between the connecting frames, a toothed disc installed at both ends of the limiting shaft and on the inner wall of the quenching tank, a chain meshing with the outer side of the toothed disc, and a metal mesh fixedly installed between the chains. The conveying assembly also includes a drive motor located on the left side of the support frame.

[0011] Preferably, the chain is ring-shaped and is mounted on the left and right sides of the quenching tank via a toothed plate. The running path of the chain in the quenching tank is an inverted trapezoidal structure, and the shaft of the drive motor is fixedly connected to the lower limiting shaft of the rear connecting frame.

[0012] Preferably, the two ends of the circulation pipe pass through the cooling pool and are located on the left and right sides of the cooling pool respectively. There are two liquid inlet pipes, which are three-way structures, and the bottom of the liquid inlet pipes is inclined. The bottom end of the liquid inlet pipe is connected to the cooling pool. The inner diameter of the liquid inlet pipe is larger than the outer diameter of the connecting pipe. The bottom end of the connecting pipe is flush with the left end of the liquid inlet pipe.

[0014] Beneficial effects

[0015] This invention provides a continuous water-cooling quenching device for the processing of alloy hammerheads in crushers. Compared with the prior art, it has the following advantages:

[0016] (1) The continuous water-cooled quenching device for the processing of alloy hammerheads of crushers uses a filter tube. The upper gear pump draws out the coolant from the quenching tank and delivers it to the inner tube of the filter tube through the connecting pipe. The coolant passes through the filter element through the opening on the surface of the inner tube of the filter tube, and then enters the cavity between the connecting pipe and the inlet pipe through the opening on the surface of the annular structure at the right end of the filter tube. Finally, it enters the cooling pool through the bottom end of the inlet pipe to filter the quenching oil. At the same time, since the inlet end of the upper gear pump is located on both sides of the hammerhead movement path, it can draw out the heated quenching oil. The quenching oil at high temperature has higher fluidity than at low temperature, which can facilitate the movement of impurities. After the quenching oil is discharged from the filter tube, the quenching oil inside the connecting pipe moves through the cavity between the inlet pipe and the connecting pipe, which can maintain the temperature of the filtered quenching oil and make it still have good fluidity after filtration.

[0017] (2) The continuous water-cooled quenching device for the processing of alloy hammerheads of crushers has a cooling pool. The left side of the cooling pool is connected to the bottom of the liquid inlet pipe. The quenching liquid is discharged into the cooling pool through the liquid inlet pipe. The part of the circulation pipe inside the cooling pool has a bent structure. Cooling water is introduced into the circulation pipe to absorb the heat of the quenching liquid and reduce the temperature of the quenching liquid. Then, the low-temperature quenching liquid is transported back to the quenching tank through the return pipe by the gear pump on the right side of the cooling pool to avoid the temperature of the quenching liquid rising during the continuous quenching process, which would affect the quenching effect.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a continuous water-cooled quenching device for the processing of alloy hammerheads in crushers, comprising a support frame 1, and a quenching mechanism 2 disposed above the support frame 1.

[0025] The conveying assembly 21, positioned above the support frame 1, is used to convey alloy hammerheads. The conveying assembly 21 includes a quenching tank 211 fixedly mounted above the support frame 1. Connecting frames 212 are fixedly mounted at both ends of the quenching tank 211. Limiting shafts 213 are interlocked between the connecting frames 212. Gear sprockets 214 are mounted at both ends of the limiting shafts 213 and on the inner wall of the quenching tank 211. Chains 215 are meshed with the outer sides of the gear sprockets 214. Metal mesh 216 is fixedly mounted between the chains 215. The conveying assembly 21 also includes a drive motor 217 located on the left side of the support frame 1. The inner wall of the quenching tank 211 is provided with a cylindrical structure that fits into the inner diameter of the toothed disc 214. The toothed disc 214 and the quenching tank 211 are rotatably connected. The toothed disc 214 and the limiting shaft 213 are fixedly connected. The limiting shaft 213 and the connecting frame 212 are rotatably connected. The chain 215 is ring-shaped and is installed on the left and right sides of the quenching tank 211 through the toothed disc 214. The running path of the chain 215 in the quenching tank 211 is an inverted trapezoidal structure. The rotating shaft of the drive motor 217 is fixedly connected to the limiting shaft 213 below the rear connecting frame 212.

[0026] Specifically, the support frame 1 can restrict the position of the quenching tank 211. The quenching tank 211 can hold a certain amount of quenching liquid. The drive motor 217 drives a limiting shaft 213 to rotate, so that the toothed disc 214 on the outside of the limiting shaft 213 drives the chain 215 to rotate. When the chain 215 rotates, it can drive the metal mesh 216 to rotate, and place the hammer head above the metal mesh 216 so that the hammer head is immersed in the quenching liquid under the action of the metal mesh 216.

[0027] The circulation assembly 22 includes a cooling pool 221 located below the support frame 1. A circulation pipe 222 is fixedly installed inside the cooling pool 221. An inlet pipe 223 is inserted through the left side of the cooling pool 221, and a connecting pipe 224 is inserted through the top of the inlet pipe 223. A gear pump 225 is fixedly installed at the upper end of the connecting pipe 224 and on the right side of the cooling pool 221. A return pipe 226 is fixedly installed at the discharge port of the gear pump 225 on the right side of the cooling pool 221. A filter pipe 227 is fixedly installed on the left side of the inlet pipe 223, and a filter element 228 is inserted through the filter pipe 227. A cover 229 is movably installed on the left side of the filter pipe 227. The two ends of the circulation pipe 222 pass through the cooling pool 221 and are located on the left and right sides of the cooling pool 221, respectively. The inlet pipe 223 has a total of There are two pipes, which are three-way structures. The bottom of the inlet pipe 223 is inclined. The bottom end of the inlet pipe 223 is connected to the cooling pool 221. The inner diameter of the inlet pipe 223 is larger than the outer diameter of the connecting pipe 224. The bottom end of the connecting pipe 224 is flush with the left end of the inlet pipe 223. The left ends of the connecting pipe 224 and the inlet pipe 223 are fixedly connected to the filter pipe 227. The filter pipe 227 is a sleeve structure. The inner tube and the outer tube are connected by an annular structure on the right side. The surface of the annular structure is provided with an annularly distributed perforation structure. The surface of the inner tube of the filter pipe 227 is provided with an array of perforations. The filter element 228 is inserted and installed between the inner tube and the outer tube of the filter pipe 227. The cap 229 is connected to the filter pipe 227 through a threaded structure. The cap 229 is fitted and connected to one end of the inner tube.

[0028] Specifically, the coolant inside the quenching tank 211 is drawn out by the upper gear pump 225 and transported to the inner tube of the filter tube 227 through the connecting pipe 224. The coolant passes through the filter element 228 through the opening on the surface of the inner tube of the filter tube 227, and then enters the cavity between the connecting pipe 224 and the inlet pipe 223 through the opening on the surface of the annular structure at the right end of the filter tube 227. Finally, it enters the cooling pool 221 through the bottom end of the inlet pipe 223. The part of the circulation pipe 222 located inside the cooling pool 221 has a bent structure. Cooling water is introduced into the circulation pipe 222 to absorb the heat of the quenching liquid.

[0029] The specific drive motor 217 is model YBK3, and the gear pump 225 is model QX22-005R76. In addition, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0030] During operation, the upper gear pump 225 draws coolant from the quenching tank 211 and delivers it through the connecting pipe 224 to the inner tube of the filter pipe 227. The coolant passes through the filter element 228 through the opening on the surface of the inner tube of the filter pipe 227, and then enters the cavity between the connecting pipe 224 and the inlet pipe 223 through the opening on the surface of the annular structure at the right end of the filter pipe 227. Finally, it enters the cooling pool 221 through the bottom end of the inlet pipe 223 to filter the quenching oil. At the same time, since the inlet end of the upper gear pump 225 is located on both sides of the hammer movement path, it can draw out the heated quenching oil. The quenching oil at high temperature has higher fluidity than at low temperature, which facilitates the movement of impurities. After the quenching oil is discharged from the filter pipe 227, it passes through the inlet pipe 227 through the cooling pool 221. The cavity between the liquid pipe 223 and the connecting pipe 224 allows the quenching oil inside the moving connecting pipe 224 to maintain the temperature of the filtered quenching oil, ensuring good fluidity after filtration. The left side of the cooling pool 221 is connected to the bottom of the inlet pipe 223, allowing the quenching liquid to be discharged into the cooling pool 221 through the inlet pipe 223. The portion of the circulation pipe 222 inside the cooling pool 221 has a bent structure. Cooling water is introduced into the circulation pipe 222 to absorb the heat of the quenching liquid and lower its temperature. Then, the low-temperature quenching liquid is pumped back to the quenching tank 211 through the return pipe 226 via the gear pump 225 on the right side of the cooling pool 221 to prevent the temperature of the quenching liquid from rising during continuous quenching, which would affect the quenching effect.
