Description

Technical Field

[0001] The invention relates to an oil quenching device, in particular to an oil quenching device for processing automobile fasteners with high safety and applied in the field of metal heat treatment. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used. Various fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters and supplies, etc. They are the most widely used mechanical basic parts. They are characterized by a wide variety of varieties and specifications, different performances and uses, and a high degree of standardization, serialization and generalization. During the processing of fasteners, quenching treatment is required.

[0003] The specification of Chinese invention patent CN202320500461.X discloses "A quenching device for bolt processing". In this patent, when the force is unbalanced, the bolt will tilt forward and fall into the inside of the chute plate. The bolt will slide along the chute plate to the inside of the water tank. The water inside the water tank will quickly cool the bolt and quench it.

[0004] The quenching time of parts is a complex parameter, which is affected by many factors. After the high-temperature parts are immersed in the quenching oil for a specified time, the quenched parts need to be taken out in time. The operation of taking out the parts is inconvenient and can easily cause production safety accidents. In addition, the parts immersed in the quenching pool are prone to sink to the bottom, which further increases the difficulty of retrieving the parts, resulting in the fasteners cannot be taken out in time, affecting the quenching quality of the fasteners. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the operation of removing parts is inconvenient, which may easily cause production safety accidents, and the parts immersed in the quenching pool are easy to sink to the bottom, further increasing the difficulty of retrieving the parts, resulting in the fasteners cannot be removed in time, affecting the quenching quality of the fasteners.

[0006] In order to solve the above problems, the present invention provides a high-safety oil quenching device for automobile fastener processing, comprising a quenching pool, the top of which is rotatably connected to a workpiece conveyor belt, a gas carburizing furnace is placed outside one end of the quenching pool, a furnace outlet window is fixedly connected to the outside of the gas carburizing furnace, the furnace outlet window extends into the quenching pool and vertically corresponds to the workpiece conveyor belt, and a discharge port is opened at the other end of the quenching pool, and the discharge port is horizontally corresponding to the workpiece conveyor belt;

[0007] Both ends of the bottom of the furnace exit window are fixedly connected with telescopic cylinders, and the output ends of the telescopic cylinders are fixedly connected with gathering rail grooves, both ends of the inner wall of the quenching pool are fixedly connected with limiting rail grooves, the left and right edges of the workpiece conveyor belt are fixedly connected with limiting edges, the gathering rail grooves and the limiting rail grooves are slidingly connected to the limiting edges, and elastic gathering ribs are fixedly connected between the two limiting edges, and both ends of the surface of the workpiece conveyor belt are fixedly connected with reinforcement ribs, and both ends of the elastic gathering ribs penetrate the reinforcement ribs.

[0008] In the above-mentioned high-safety oil quenching device for processing automotive fasteners, the telescopic cylinder is used to push the convergent rail grooves together, so that the middle part of the workpiece conveyor belt bends and sinks below the quenching oil level, and catches the high-temperature fasteners that fall out of the furnace window. Subsequently, the workpiece conveyor belt drives the quenched fasteners to be fished out, effectively improving the safety effect of the quenching production of automotive fasteners.

[0009] As a further improvement of the present application, the surface of the workpiece conveyor belt is provided with seepage holes, and the workpiece conveyor belt is woven from a high-temperature resistant fiber material. The high-temperature resistant fiber material woven from the workpiece conveyor belt effectively improves the high-temperature resistance of the workpiece conveyor belt, and the seepage holes facilitate the quenching oil to float on the upper surface of the workpiece conveyor belt.

[0010] As a further improvement of the present application, the middle part of the elastic gathering ribs is curved in a wave shape, and the elastic gathering ribs are made of spring steel material. The elastic gathering ribs are utilized to gather the middle part of the workpiece conveyor belt to facilitate the bending, sinking and deformation of the workpiece conveyor belt, and the elastic gathering ribs are straightened as the workpiece conveyor belt is tightened, thereby effectively reducing the influence of the elastic gathering ribs on the surface flatness of the workpiece conveyor belt when the workpiece conveyor belt is in a planar state.

[0011] As a further improvement of the present application, a flushing pipe is fixedly connected to the bottom of the quenching pool, and an upwelling port is fixedly connected to one end of the flushing pipe. The upwelling port vertically corresponds to the furnace outlet window. The flushing pipe guides the flow of quenching oil in the quenching pool to adjust the heat distribution of the quenching oil in the quenching pool. The quenching oil is sprayed from the upwelling port to the sinking workpiece conveyor belt, and the upwelling quenching oil flushes the surface of the workpiece, effectively improving the surface cleaning effect of the workpiece.

[0012] As another improvement of the present application, the other end of the flushing pipe is fixedly connected to a circulating pump, and the external fixed sleeve of the circulating pump is provided with a filter cartridge, which is fixedly connected to the bottom of the quenching tank. The quenching oil in the quenching tank is driven into the flushing pipe by the circulating pump, which facilitates the circulation of the quenching oil, and the filter cartridge is used to provide protection for the liquid inlet of the circulating pump, thereby effectively improving the service life of the circulating pump.

[0013] As another improvement supplement to the present application, a fixing frame is fixedly connected to the top of one end of the quenching pool near the discharge port, and a cleaning fan is fixedly connected to the top of the fixing frame. The air outlet end of the cleaning fan vertically corresponds to the workpiece conveyor belt. The cleaning fan is utilized to blow air on the workpiece conveyor belt to separate the residual quenching oil on the workpiece, and return it to the quenching pool through the workpiece conveyor belt.

[0014] As another improvement supplement of the present application, an electric heating mesh plate is fixedly connected to the middle part of the fixed frame, and the electric heating mesh plate vertically corresponds to the air outlet end of the cleaning fan. The electric heating mesh plate heats the air blown by the cleaning fan, effectively reducing the influence of air flow on the temperature of the workpiece, thereby avoiding affecting the quenching quality of the workpiece.

[0015] As another improvement of the present application, the left and right ends of the fixed frame are movably connected with vibrating feet, and the bottom end surface of the vibrating feet is in close contact with the surface of the workpiece conveyor belt. The vibrating feet are utilized to drive the workpiece conveyor belt to vibrate, thereby further improving the shedding of quenching oil on the workpiece conveyor belt and the workpiece, and effectively improving the recovery effect of the quenching oil.

[0016] As another improvement supplement of the present application, both ends of the bottom of the two vibrating foot plates are curved and upward, and the tops of the two vibrating foot plates are fixedly connected to vibration motors, which drive the vibrating foot plates to vibrate up and down, effectively improving the vibration effect of the vibrating foot plates.

[0017] As another improvement supplement of the present application, the two ends of the bottom of the two vibrating foot plates facing each other are fixedly connected with shovel blades, which are arranged obliquely corresponding to the conveying direction of the workpiece conveyor belt, and the shovel blades are in close contact with the surface of the workpiece conveyor belt. The shovel blades are used to move the workpieces on the surface of the workpiece conveyor belt to adjust the placement of the workpieces on the workpiece conveyor belt, thereby improving the separation effect of the quenching oil.

[0018] In summary, the present invention pushes the convergent rail grooves together by the telescopic cylinder, thereby limiting the conveying space of the workpiece conveyor belt, and the elastic gathering ribs pull the middle part of the workpiece conveyor belt to achieve the bending and sinking of the middle part of the workpiece conveyor belt below the quenching oil level. The middle part of the workpiece conveyor belt forms a pocket-like structure, and catches the high-temperature fasteners that fall out of the furnace window, effectively preventing the fastened workpieces from sinking to the bottom of the quenching pool, and effectively improving the safety performance of the quenching device by reducing the difficulty of salvaging the workpiece. The high-temperature workpiece contacts the quenching oil to complete the quenching process, and the gathered elastic gathering ribs intercept the workpieces on the workpiece conveyor belt laterally, effectively improving the contact effect between the quenched workpiece and the workpiece conveyor belt, making it convenient for the workpiece conveyor belt to bring out the quenched fasteners in time, and effectively improving the quenching production safety effect of automotive fasteners.

[0031] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-3It is shown that an oil quenching device for processing high-safety automotive fasteners comprises a quenching pool 1, the top of the quenching pool 1 is rotatably connected to a workpiece conveyor belt 101, a gas carburizing furnace 2 is placed outside one end of the quenching pool 1, and a furnace outlet window 201 is fixedly connected to the outside of the gas carburizing furnace 2, the furnace outlet window 201 extends into the quenching pool 1 and vertically corresponds to the workpiece conveyor belt 101, a discharge port 102 is provided at the other end of the quenching pool 1, the discharge port 102 is horizontally corresponding to the workpiece conveyor belt 101, a liquid seepage hole 103 is provided on the surface of the workpiece conveyor belt 101, and the workpiece conveyor belt 101 is woven from a high-temperature resistant fiber material, which effectively improves the high-temperature resistance of the workpiece conveyor belt 101, and the quenching oil is convenient to float on the upper surface of the workpiece conveyor belt 101 through the liquid seepage hole 103;

[0034] When performing quenching processing on automobile fastening workpieces, the fastening workpieces are first subjected to high-temperature carburizing treatment in the gas carburizing furnace 2. The treated fastening workpieces are sent into the quenching pool 1 through the furnace exit window 201, and the fastening workpieces fall into the quenching pool 1 for quenching processing. The quenching oil passes through the seepage hole 103 and covers the workpiece conveyor belt 101. The quenched fastening workpieces fall on the workpiece conveyor belt 101, and then the workpiece conveyor belt 101 automatically takes the fastening workpieces out of the quenching pool 1, so that the workpieces can be taken out in time after quenching, and the workpieces can be effectively prevented from being immersed in the quenching oil for a long time, thereby effectively improving the quenching quality of the workpieces and effectively avoiding quenching production accidents.

[0035] Figure 3-6 As shown, both ends of the bottom of the furnace window 201 are fixedly connected with a telescopic cylinder 202, and the output ends of the telescopic cylinder 202 are fixedly connected with a gathering rail groove 203, both ends of the inner wall of the quenching pool 1 are fixedly connected with a limiting rail groove 204, and the left and right edges of the workpiece conveyor belt 101 are fixedly connected with a limiting edge 205, and the gathering rail groove 203 and the limiting rail groove 204 are both slidably connected to the limiting edge 205, and an elastic gathering rib 206 is fixedly connected between the two limiting edges 205, and both ends of the surface of the workpiece conveyor belt 101 are fixedly connected with a reinforcement The reinforcing rib 207, both ends of the elastic gathering rib 206 penetrate the reinforcing rib 207, the middle part of the elastic gathering rib 206 is curved in a wave shape, and the elastic gathering rib 206 is made of spring steel material. The elastic gathering rib 206 is used to gather the middle part of the workpiece conveyor belt 101, which is convenient for the bending, sinking and deformation of the workpiece conveyor belt 101, and the elastic gathering rib 206 is straightened as the workpiece conveyor belt 101 is tightened, which effectively reduces the influence of the elastic gathering rib 206 on the surface flatness of the workpiece conveyor belt 101 when the workpiece conveyor belt 101 is in a plane state;

[0036] When the workpiece conveyor belt 101 rotates to the bottom of the furnace exit window 201, the telescopic cylinder 202 pushes the gathering rail grooves 203 to close together, so that the spacing of the gathering rail grooves 203 is smaller than the spacing of the limiting rail grooves 204, so the width of the workpiece conveyor belt 101 is limited, and the elastic gathering ribs 206 pull the middle part of the workpiece conveyor belt 101 to achieve the bending and sinking of the middle part of the workpiece conveyor belt 101 below the quenching oil level, and the middle part of the workpiece conveyor belt 101 forms a pocket-shaped structure to catch the high-temperature fasteners dropped out of the furnace exit window 201, and the spacing of the limiting rail grooves 204 corresponds to the width of the workpiece conveyor belt 101. The lateral width allows the workpiece conveyor belt 101 to restore a flat transmission state, effectively preventing the fastened workpiece from sinking to the bottom of the quenching pool 1, thereby effectively improving the quenching stability of the workpiece, reducing the difficulty of salvaging the quenched workpiece, and effectively improving the safety performance of the quenching process. The high-temperature workpiece contacts the quenching oil to complete the quenching process. The gathered elastic gathering ribs 206 intercept the workpiece on the workpiece conveyor belt 101 laterally, effectively improving the contact effect between the quenched workpiece and the workpiece conveyor belt 101, making it convenient for the workpiece conveyor belt 101 to bring out the quenched fasteners in time, effectively improving the quenching production safety effect of automotive fasteners.

[0037] Figure 2 and Figure 7 As shown, a flushing pipe 104 is fixedly connected to the bottom of the quenching pool 1, and an upwelling port 105 is fixedly connected to one end of the flushing pipe 104. The upwelling port 105 corresponds vertically to the furnace exit window 201. The flushing pipe 104 guides the quenching oil in the quenching pool 1 to flow, adjusts the heat distribution of the quenching oil in the quenching pool 1, and the quenching oil is ejected from the upwelling port 105 to the sinking workpiece conveyor belt 101. The upwelling quenching oil flushes the surface of the workpiece, effectively improving the surface cleaning effect of the workpiece. A circulating pump 106 is fixedly connected to the other end of the flushing pipe 104. A filter cartridge 107 is fixedly sleeved on the outside of the circulating pump 106. The filter cartridge 107 is fixedly connected to the bottom of the quenching pool 1. The quenching oil in the quenching pool 1 is driven into the flushing pipe 104 through the circulating pump 106, which is convenient for the circulation of the quenching oil. The filter cartridge 107 is used to provide protection for the liquid inlet of the circulating pump 106, effectively improving the service life of the circulating pump 106.

[0038] The quenching oil in the quenching pool 1 is driven into the flushing pipe 104 by the circulation pump 106 to realize the circulation flow of the quenching oil in the quenching pool 1, and the heat distribution of the quenching oil in the quenching pool 1 is adjusted. The quenching oil is sprayed out from the upwelling port 105 to the sinking workpiece conveyor belt 101. The upwelling quenching oil flushes the surface of the workpiece, effectively improving the surface cleaning effect of the workpiece. The filter cartridge 107 provides protection for the liquid inlet of the circulation pump 106, effectively improving the service life of the circulation pump 106.

[0039] The second implementation method:

[0040] Compared with the first embodiment, this embodiment mainly adds a cleaning fan 301 and a vibrating foot plate 303. The specific newly added structures are as follows, and the remaining structures are consistent with the first embodiment.

[0041] Figure 8-9 As shown, a fixing frame 3 is fixedly connected to the top of one end of the quenching pool 1 close to the discharge port 102, a cleaning fan 301 is fixedly connected to the top of the fixing frame 3, the air outlet end of the cleaning fan 301 corresponds vertically to the workpiece conveyor belt 101, the cleaning fan 301 is used to blow air to the workpieces on the workpiece conveyor belt 101, so as to separate the residual quenching oil on the workpieces and return it to the quenching pool 1 through the workpiece conveyor belt 101, and an electric heating mesh plate 302 is fixedly connected to the middle part of the fixing frame 3, the electric heating mesh plate 302 corresponds vertically to the air outlet end of the cleaning fan 301, and the electric heating mesh plate 302 heats the air blown out by the cleaning fan 301, so as to effectively reduce the influence of air flow on the temperature of the workpiece, thereby avoiding affecting the quenching quality of the workpiece;

[0042] When the workpiece conveyor belt 101 recovers its flat state to transport the workpiece, the cleaning fan 301 blows air to the workpiece on the workpiece conveyor belt 101 after quenching, so as to remove the residual quenching oil on the workpiece, and the quenching oil flows back into the quenching pool 1 through the workpiece conveyor belt 101, so as to recover the quenching oil. The electric heating grid plate 302 heats the air blown out by the cleaning fan 301, so as to effectively reduce the influence of air flow on the temperature of the workpiece, that is, the cooling speed of the workpiece is too fast, thereby avoiding affecting the quenching quality of the workpiece.

[0043] Figure 9-10 As shown, both left and right ends of the fixing frame 3 are movably connected with a vibrating foot plate 303, and the bottom end surface of the vibrating foot plate 303 is in close contact with the surface of the workpiece conveyor belt 101. The vibrating foot plate 303 is used to drive the workpiece conveyor belt 101 to vibrate, thereby further improving the shedding of the quenching oil on the workpiece conveyor belt 101 and the workpiece, and effectively improving the recovery effect of the quenching oil. The bottom ends of the two vibrating foot plates 303 are bent and upturned, and the tops of the two vibrating foot plates 303 are fixedly connected with a vibrating motor 304. 304 drives the vibrating foot plate 303 to vibrate up and down, effectively improving the vibration effect of the vibrating foot plate 303. The two ends of the bottom of the two vibrating foot plates 303 facing each other are fixedly connected with shovel blades 305. The shovel blades 305 are arranged obliquely corresponding to the conveying direction of the workpiece conveyor belt 101, and the shovel blades 305 are in close contact with the surface of the workpiece conveyor belt 101. The shovel blades 305 are used to move the workpieces on the surface of the workpiece conveyor belt 101 to adjust the placement of the workpieces on the workpiece conveyor belt 101, thereby improving the separation effect of the quenching oil.

[0044] When the quenched workpiece is transmitted on the flat workpiece conveyor belt 101, the vibration motor 304 drives the vibration foot plate 303 to vibrate up and down, and the vibration of the workpiece conveyor belt 101 is realized by the vibration foot plate 303, so as to further improve the shedding of quenching oil on the workpiece conveyor belt 101 and the workpiece, and effectively improve the recovery effect of the quenching oil. At the same time, the shovel 305 moves the workpiece on the surface of the workpiece conveyor belt 101, and adjusts the placement of the workpiece on the workpiece conveyor belt 101, so as to improve the separation effect of the quenching oil.

[0045] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
