Description

Technical Field

[0001] The invention belongs to the technical field of fastener processing, and in particular relates to deep dehydrogenation equipment and a method for automobile fasteners. Background Art

[0002] The deep dehydrogenation equipment for automotive fasteners is mainly used to remove hydrogen that may be absorbed by fasteners during electroplating and other processes to improve the mechanical properties and corrosion resistance of fasteners. The deep dehydrogenation equipment for automotive fasteners is a heat treatment equipment specially designed for automotive fasteners (such as bolts, nuts, washers, etc.). It removes hydrogen inside the fasteners by heating and baking, prevents the occurrence of hydrogen embrittlement, and improves the reliability and durability of the fasteners. Its main principle is to use the hot air circulation electric bottom dehydrogenation furnace oven air circulation system, use the fan to circulate air, ensure the temperature uniformity in the box to achieve the dehydrogenation operation of the fasteners.

[0003] When performing deep dehydrogenation of automotive fasteners, the box is generally sealed and the fasteners are placed inside the box, and the deep dehydrogenation operation is achieved through hot air circulation. Although this operation method can dry the fasteners, when the fasteners are in a disorderly placement state and in contact with the tray, it is necessary to change their placement position multiple times to complete complete baking, and the overall dehydrogenation efficiency is low.

[0004] At the same time, since hot air is used for high-temperature baking, and fasteners are generally made of metal with good thermal conductivity, after the high-temperature baking of the fasteners is completed, it is usually necessary to open the sealed box and wait for the heat inside to completely dissipate, that is, the fasteners can be taken out after cooling down. Although this operation method can avoid burns to operators, it usually requires a long cooling time when discharging, which further reduces the dehydrogenation efficiency and urgently needs to be improved. Summary of the invention

[0005] The object of the present invention is to provide a deep dehydrogenation device and method for automobile fasteners to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a deep dehydrogenation equipment for automobile fasteners, comprising a sealed box, cover plates are provided on the front and rear sides of the top of the sealed box, lateral guide rails are fixedly installed on the left and right sides of the inner cavity of the sealed box near the top, guide blocks are symmetrically installed on the front and rear sides between the two lateral guide rails, the guide blocks are movably connected with the lateral guide rails, the guide blocks are displaced forward and backward relative to the lateral guide rails, a clamping plate is fixedly installed between the two guide blocks, the two clamping plates are designed to be symmetrical front and back, and fixing grooves are equidistantly provided on the sides of the two clamping plates that are relatively close to each other, a bottom plate is provided at the bottom end of the clamping plate, mounting plates are fixedly installed on the left and right ends of the bottom plate, linkage components are fixedly installed on the top of the mounting plates, the top of the linkage components is connected to the bottom end of the guide blocks, a gas transmission component is fixedly installed on the bottom end of the mounting plate, a gas circulation component is installed at the rear end of the sealed box, and one end of the gas circulation component is connected to the gas transmission component.

[0007] Before the dehydrogenation operation of the automobile fasteners is performed, the two clamps are in a state of being away from each other, and the distance between the top of the bottom plate and the top of the sealing box is at a minimum value. At the same time, the two cover plates are away from each other, the top of the sealing box is in an open state, and the device as a whole is in an initial state.

[0008] As a further technical solution of the present invention, a sealing strip is fixedly installed at one end of the two cover plates that are relatively close to each other, the bottom ends of the two cover plates are connected to the top of the guide block, and the top of the bottom plate is provided with air holes in a matrix shape.

[0009] When it is necessary to dehydrogenate the fasteners, the fasteners can be neatly placed on the top of the base plate, that is, the fasteners and the base plate are kept perpendicular to each other and placed between the two fixing grooves, that is, the outer side of the fastener is located between the two fixing grooves, and the bottom end of the fastener is in contact with the top of the base plate.

[0010] As a further technical solution of the present invention, the gas circulation component includes a hot air blower, one end of which is connected to the rear end of the sealing box, the output end of the hot air blower is fixedly connected to a four-way valve, and the rear end of the four-way valve is fixedly connected to an air intake pipe.

[0011] As a further technical solution of the present invention, a circulation pipe is fixedly connected to the top of the four-way valve, and the other end of the circulation pipe is connected to the rear side of the sealing box near the top. The left and right sides of the four-way valve are fixedly connected to gas pipes, and the other end of the gas pipe is connected to the gas supply assembly. A one-way valve is installed inside the circulation pipe, and the direction of the valve is to conduct to the inside of the four-way valve and to cut off to the outside of the four-way valve.

[0012] When dehydrogenation of fasteners is performed, the hot air blower can be turned on to inhale external air into the four-way valve, and after heating, it can be discharged to the inside of the gas delivery component through the gas delivery pipe. At the same time, due to the rising characteristics of hot air, the hot air inside the sealed box can be discharged through the circulation pipe after rising, and re-enter the inside of the four-way valve, and re-enter the inside of the gas delivery component through the gas delivery pipe, and finally enter the inside of the sealed box to complete the cycle;

[0013] And when the dehydrogenation operation is completed, the heating of the hot air blower can be stopped, and cold air can be sucked into the inside of the four-way valve and introduced into the inside of the sealed box through the air pipe to quickly cool down the sealed box. At the same time, the residual hot air discharged from the circulation pipe can be discharged through the air intake pipe, and air circulation is no longer performed, completing the rapid cooling process.

[0014] By utilizing the circulation pipelines of the circulation pipe and the gas pipe, during baking, the rising hot air can be reintroduced into the interior of the sealed box to achieve hot air circulation, thereby reducing heat loss and energy consumption. At the same time, after baking, the air circulation can be stopped, cold air can be input and hot air can be exhausted to achieve rapid cooling of the interior of the sealed box, which not only reduces the energy consumption during hydrogen removal, but also achieves rapid cooling of the device.

[0015] As a further technical solution of the present invention, the gas delivery assembly includes a gas storage pipe, a base is fixedly installed at the bottom end of the gas storage pipe, the bottom end of the base is connected to the bottom end of the inner cavity of the sealing box, and a three-way valve is fixedly connected to the side of the gas storage pipe close to the top, and the side of the three-way valve away from the gas storage pipe is connected to the gas delivery pipe.

[0016] As a further technical solution of the present invention, the internal movable sleeve of the gas storage pipe is provided with a movable plate, the top of the movable plate is fixedly connected with a movable rod, the top of the movable rod passes through the top of the gas storage pipe and is connected to the bottom of the mounting plate.

[0017] As a further technical solution of the present invention, the bottom end of the movable plate is fixedly connected to a limit spring located inside the gas storage pipe, and the bottom end of the limit spring is connected to the bottom end of the inner cavity of the gas storage pipe.

[0018] As a further technical solution of the present invention, the bottom end of the three-way valve is fixedly connected with a bend pipe, and the other end of the bend pipe passes through one side of the base and is fixedly connected with a nozzle located at the bottom end of the inner cavity of the sealing box.

[0019] When hot air enters the interior of the three-way valve through the air delivery pipe, the valve on the left end of the three-way valve can be opened, and air then enters the interior of the air storage pipe, exerts pressure on the movable plate and drives the movable plate down. At this time, the limit spring is compressed, and the movable rod descends and drives the mounting plate down, completing power transmission;

[0020] At the same time, after the power transmission is completed, the valve at the bottom of the three-way valve can be opened to guide the hot air out through the elbow and spray it into the interior of the sealed box through the nozzle, thereby completing the hot air input process.

[0021] As a further technical solution of the present invention, the linkage assembly includes a first fixed seat, which is fixedly connected to the bottom end of the guide block, and the end of the first fixed seat away from the guide block is movably connected to a connecting rod via a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft, and the bottom end of the second fixed seat is connected to the top end of the mounting plate.

[0022] When the mounting plate descends, the bottom plate is driven down synchronously, and the fastener is driven down at the same time, and the two connecting rods are deflected toward the middle, that is, the angle between the two connecting rods is reduced, and the two guide blocks are driven relatively close to each other. At this time, the two clamping plates are relatively close to each other until the fastener located between the two fixing grooves is clamped, completing the limiting process of the fastener, and the two cover plates at the top are relatively close to each other until the two sealing strips are in close contact, completing the sealing process.

[0023] By utilizing the hot air required for the dehydrogenation operation and introducing the hot air into the interior of the gas delivery component, the bottom plate is lowered by the action of the gas delivery component, and the two clamping plates are brought relatively close by the lowering of the bottom plate, thereby realizing the automatic clamping process of the fasteners. The fasteners can be limited in position during the dehydrogenation process so that they can be placed in an orderly manner. At the same time, the clamping position can be fully baked by loosening the limit, thereby avoiding the problem that traditional devices need to change the placement position many times to achieve complete baking, thereby improving the overall dehydrogenation efficiency.

[0024] When the dehydrogenation operation of the fastener is completed and it is necessary to discharge it, the air input can be stopped, that is, the hot air blower can be turned off. At this time, the limit spring can be automatically reset and drive the movable rod to rise. At this time, the mounting plate rises and resets accordingly, which can drive the bottom plate to rise synchronously. At the same time, the linkage assembly automatically resets and drives the two clamps to move away from each other, loosening the fasteners, and the two cover plates move away from each other, opening the sealing box, and the bottom plate drives the fasteners to automatically rise to expose the top of the sealing box, so that it leaves the high temperature environment, completing the rapid cooling and discharging process.

[0025] By utilizing the shutdown process of the device, that is, stopping the input of air, the device is reset, and the fasteners are automatically raised, the limit is automatically released, and the top of the sealing box is automatically opened through the resetting of the device, so that the hot air inside the sealing box can be quickly discharged, and the fasteners can be taken away from the high temperature environment to complete automatic unloading and quickly cool down. The whole process is completed automatically, effectively avoiding the problem that traditional devices require manual unloading and a long cooling time, shortening the cooling time, and improving the unloading efficiency.

[0026] A method for using a deep dehydrogenation device for automobile fasteners comprises the following steps:

[0027] S1: Before dehydrogenation of fasteners, the device is in the initial state, that is, the two cover plates are away from each other, and the interior of the sealed box is in an open state. At the same time, the fasteners can be placed on the top of the bottom plate, and the placement position of the fasteners can be made to correspond to the fixing grooves, and the device power supply is turned on to complete the preparations before dehydrogenation;

[0028] S2: By turning on the hot air blower, the external air can be sucked into the inside of the four-way valve, heated and discharged through the air pipe to enter the inside of the air delivery component. At this time, the air can enter the inside of the three-way valve and the inside of the air storage pipe, which can drive the movable rod to move downward, and at the same time drive the mounting plate to move downward. At this time, the bottom plate moves downward synchronously, and when the mounting plate moves downward, the two clamping plates can be driven close to each other under the action of the linkage component to complete the clamping process of the fastener;

[0029] S3: When the two clamping plates are close to each other, the two cover plates can be driven to be close to each other synchronously. When the fasteners are clamped, the two sealing strips contact each other to complete the sealing process of the sealing box.

[0030] S4: At the same time, the hot air can be discharged through the elbow and the nozzle, and enter the inside of the sealing box to heat and bake the fasteners to remove hydrogen. At the same time, the rising hot air can be discharged through the circulation pipe, and enter the inside of the four-way valve, and then complete the circulation again through the gas transmission pipe;

[0031] S5: After the baking and dehydrogenation is completed, the gas transmission component can be automatically reset by stopping the air input. At this time, the mounting plate rises accordingly, and the linkage component automatically resets, the bottom plate rises accordingly, and the two cover plates are automatically separated. At the same time, the two clamping plates automatically release the limit on the fasteners, and the top of the sealing box is automatically exposed. The fasteners rise to the top of the cover plate, completing the automatic discharge process.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. The present invention utilizes the hot air required for the dehydrogenation operation, introduces the hot air into the interior of the gas delivery assembly, and realizes the lowering of the bottom plate through the action of the gas delivery assembly. The lowering of the bottom plate realizes the relative proximity of the two clamping plates, thereby realizing the automatic clamping process of the fasteners, so that the fasteners can be limited in the dehydrogenation process and placed in order. At the same time, the clamping position can be fully baked by loosening the limit, avoiding the problem that the traditional device needs to change the placement position many times to achieve complete baking, thereby improving the overall dehydrogenation efficiency.

[0034] 2. The present invention utilizes the shutdown process of the device, that is, stops the input of air, to achieve the resetting of the device, and through the resetting of the device, the fasteners are automatically raised, the limit is automatically released, and the top of the sealing box is automatically opened, so that the hot air inside the sealing box is quickly discharged, and the fasteners are taken away from the high temperature environment, and the automatic discharge is completed, and the temperature is quickly cooled. The whole process is completed automatically, which effectively avoids the problem that the traditional device needs manual discharge and a long cooling time, shortens the cooling time, and improves the discharge efficiency.

[0035] 3. The present invention utilizes the circulation pipelines of the circulation pipe and the air delivery pipe to realize the circulation of hot air by reintroducing the rising hot air into the interior of the sealed box during baking, thereby reducing heat loss and energy consumption. At the same time, after the baking is completed, the air circulation can be stopped, cold air can be input and hot air can be discharged, so that the interior of the sealed box can be quickly cooled down, which not only reduces the energy consumption during hydrogen removal, but also realizes rapid cooling of the device.

[0049] Before the dehydrogenation operation of the automobile fasteners is performed, the two clamps 7 are in a state of being away from each other, and the distance between the top of the bottom plate 9 and the top of the sealing box 1 is at a minimum value. At the same time, the two cover plates 2 are away from each other, and the top of the sealing box 1 is in an open state, and the device as a whole is in an initial state.

[0050] like Figure 1 and Figure 2 as well as Figure 5 and Figure 7As shown, a sealing strip 3 is fixedly installed at one end of the two cover plates 2 that are relatively close to each other, the bottom ends of the two cover plates 2 are connected to the top end of the guide block 6, and the top end of the bottom plate 9 is provided with air holes 10 in a matrix shape.

[0051] When it is necessary to dehydrogenate the fasteners, the fasteners can be neatly placed on the top of the base plate 9, that is, the fasteners and the base plate 9 are kept perpendicular to each other and placed between the two fixing grooves 8, that is, the outer side of the fastener is located between the two fixing grooves 8, and the bottom end of the fastener is in contact with the top of the base plate 9.

[0052] like Figure 2 and Figure 3 As shown, the gas circulation component 4 includes a hot air blower 401, one end of the hot air blower 401 is connected to the rear end of the sealed box 1, the output end of the hot air blower 401 is fixedly connected to a four-way valve 402, the rear end of the four-way valve 402 is fixedly connected to an air inlet pipe 403, the top of the four-way valve 402 is fixedly connected to a circulation pipe 405, the other end of the circulation pipe 405 is connected to the rear side of the sealed box 1 near the top, the left and right sides of the four-way valve 402 are fixedly connected to an air supply pipe 404, the other end of the air supply pipe 404 is connected to the air supply component 13, and a one-way valve is installed inside the circulation pipe 405, and the direction of the valve is to conduct to the inside of the four-way valve 402 and to cut off from the outside of the four-way valve 402.

[0053] When the dehydrogenation operation of the fastener is performed, the external air can be sucked into the inside of the four-way valve 402 by turning on the hot air blower 401, and after being heated, it can be guided to the inside of the gas delivery component 13 through the gas delivery pipe 404. At the same time, due to the rising characteristic of hot air, the hot air inside the sealed box 1 can be guided through the circulation pipe 405 after rising, and re-enter the inside of the four-way valve 402, and re-enter the inside of the gas delivery component 13 through the gas delivery pipe 404, and finally enter the inside of the sealed box 1 to complete the cycle;

[0054] When the dehydrogenation operation is completed, the heating of the hot air blower 401 can be stopped, and cold air can be sucked into the inside of the four-way valve 402 and introduced into the inside of the sealed box 1 through the air supply pipe 404 to quickly cool down the sealed box 1. At the same time, the residual hot air discharged from the circulation pipe 405 can be discharged through the air intake pipe 403, and air circulation is no longer performed, thereby completing the rapid cooling process.

[0055] By utilizing the circulation pipelines of the circulation pipe 405 and the air supply pipe 404, during baking, the rising hot air can be reintroduced into the interior of the sealed box 1 to achieve hot air circulation, thereby reducing heat loss and energy consumption. At the same time, after baking, the air circulation can be stopped, cold air can be input and hot air can be exhausted, thereby achieving rapid cooling of the interior of the sealed box 1, which not only reduces the energy consumption during hydrogen removal, but also achieves rapid cooling of the device.

[0056] like Figure 3 and Figure 6 as well as Figure 8 and Fig. 9 As shown, the gas delivery assembly 13 includes a gas storage pipe 131, a base 132 is fixedly installed at the bottom end of the gas storage pipe 131, the bottom end of the base 132 is connected to the bottom end of the inner cavity of the sealed box 1, a three-way valve 133 is fixedly connected to the side of the gas storage pipe 131 close to the top, and the side of the three-way valve 133 away from the gas storage pipe 131 is connected to the gas delivery pipe 404, and a movable plate 135 is movably sleeved inside the gas storage pipe 131, and a movable rod 134 is fixedly connected to the top of the movable plate 135. The top end of the movable rod 134 passes through the top end of the gas storage pipe 131 and is connected to the bottom end of the mounting plate 12. The bottom end of the movable plate 135 is fixedly connected to a limit spring 136 located inside the gas storage pipe 131. The bottom end of the limit spring 136 is connected to the bottom end of the inner cavity of the gas storage pipe 131. The bottom end of the three-way valve 133 is fixedly connected to a bend pipe 137. The other end of the bend pipe 137 passes through one side of the base 132 and is fixedly connected to a nozzle 138 located at the bottom end of the inner cavity of the sealing box 1.

[0057] When hot air enters the interior of the three-way valve 133 through the air delivery pipe 404, the valve at the left end of the three-way valve 133 can be opened, and the air then enters the interior of the air storage pipe 131, exerts pressure on the movable plate 135 and drives the movable plate 135 to descend, and the limit spring 136 is compressed, and the movable rod 134 descends and drives the mounting plate 12 to descend, completing the power transmission;

[0058] At the same time, when the power transmission is completed, the valve at the bottom end of the three-way valve 133 can be opened, and the hot air can be discharged through the elbow 137 and sprayed into the interior of the sealed box 1 through the nozzle 138, thereby completing the hot air input process.

[0059] like Figure 4 and Figure 6 as well as Figure 7 and Fig.10 As shown, the linkage assembly 11 includes a first fixed seat 111, which is fixedly connected to the bottom end of the guide block 6, and the end of the first fixed seat 111 away from the guide block 6 is movably connected to a connecting rod 113 through a rotating shaft, and the end of the connecting rod 113 away from the first fixed seat 111 is movably connected to a second fixed seat 112 through a rotating shaft, and the bottom end of the second fixed seat 112 is connected to the top end of the mounting plate 12.

[0060] Embodiment: When the mounting plate 12 descends, the bottom plate 9 is driven down synchronously, and the fastener is driven down at the same time, and the two connecting rods 113 are deflected toward the middle, that is, the angle between the two connecting rods 113 is reduced, and the two guide blocks 6 are driven to be relatively close to each other. At this time, the two clamping plates 7 are relatively close to each other until the fastener located between the two fixing grooves 8 is clamped, completing the limiting process of the fastener, and the two cover plates 2 at the top are relatively close to each other until the two sealing strips 3 are in close contact, completing the sealing process.

[0061] By utilizing the hot air required for the dehydrogenation operation and introducing the hot air into the interior of the gas delivery component 13, the bottom plate 9 is lowered by the action of the gas delivery component 13, and the two clamping plates 7 are brought relatively close to each other by the lowering of the bottom plate 9, thereby realizing an automatic clamping process for the fasteners, so that the fasteners can be limited in position during the dehydrogenation process so that they can be placed in an orderly manner, and at the same time, the clamping position can be fully baked by loosening the limit, thereby avoiding the problem that the traditional device needs to change the placement position many times to achieve complete baking, thereby improving the overall dehydrogenation efficiency.

[0062] Embodiment: When the dehydrogenation operation of the fastener is completed and it is necessary to discharge it, the air input can be stopped, that is, the hot air blower 401 is turned off. At this time, the limit spring 136 can be automatically reset and drive the movable rod 134 to rise. At this time, the mounting plate 12 rises and resets accordingly, which can drive the bottom plate 9 to rise synchronously. At the same time, the linkage assembly 11 automatically resets and drives the two clamping plates 7 to move away from each other, loosening the fasteners, and the two cover plates 2 move away from each other, opening the sealing box 1, and the bottom plate 9 drives the fasteners to automatically rise to expose the top of the sealing box 1, so that it leaves the high temperature environment, completing the rapid cooling and discharging process.

[0063] By utilizing the shutdown process of the device, that is, stopping the input of air, the device is reset, and the fasteners are automatically raised, the limit is automatically released, and the top of the sealing box 1 is automatically opened through the resetting of the device, so that the hot air inside the sealing box 1 can be quickly discharged, and the fasteners can be taken away from the high temperature environment, and automatic discharging is completed, and the temperature is quickly cooled. The whole process is completed automatically, which effectively avoids the problem that traditional devices require manual discharging and a long cooling time, shortens the cooling time, and improves the discharging efficiency.

[0064] A method for using a deep dehydrogenation device for automobile fasteners comprises the following steps:

[0065] S1: Before dehydrogenation of the fasteners, the device is in the initial state, that is, the two cover plates 2 are away from each other, and the interior of the sealed box 1 is in an open state. At the same time, the fasteners can be placed on the bottom plate 9, and the placement position of the fasteners can be made to correspond to the fixing grooves 8, and the device power is turned on to complete the preparations before dehydrogenation;

[0066] S2: By turning on the hot air blower 401, the external air can be sucked into the inside of the four-way valve 402, and after being heated, it is led out through the air delivery pipe 404 to enter the inside of the air delivery component 13. At this time, the air can enter the inside of the three-way valve 133 and the inside of the air storage pipe 131, which can drive the movable rod 134 to move downward, and at the same time drive the mounting plate 12 to move downward. At this time, the bottom plate 9 moves downward synchronously, and when the mounting plate 12 moves downward, the two clamping plates 7 can be driven to approach each other under the action of the linkage component 11 to complete the clamping process of the fastener;

[0067] S3: When the two clamping plates 7 are close to each other, the two cover plates 2 can be driven to be relatively close to each other synchronously. When the clamping of the fasteners is completed, the two sealing strips 3 are in contact with each other to complete the sealing process of the sealing box 1;

[0068] S4: At the same time, the hot air can be discharged through the elbow 137 and the nozzle 138, and enter the interior of the sealing box 1 to heat and bake the fasteners to remove hydrogen. At the same time, the rising hot air can be discharged through the circulation pipe 405, and enter the interior of the four-way valve 402, and then pass through the air pipe 404 again to complete the circulation;

[0069] S5: After the baking and dehydrogenation are completed, the gas delivery component 13 can be automatically reset by stopping the air input. At this time, the mounting plate 12 rises accordingly, and the linkage component 11 automatically resets, the bottom plate 9 rises accordingly, and the two cover plates 2 are automatically separated.
