DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figure 1 As shown, the present invention provides a technical solution: a heat treatment device for a woodworking drill bit, comprising: A shell body 1 and a placement tray 15 for placing a woodworking drill bit, a guide groove 4 is opened on the upper part of one side of the shell body 1, a pusher clamping assembly 5 for conveying the placement tray 15 with the woodworking drill bit placed on it to the inside of the shell body 1 is arranged inside the guide groove 4, a plurality of connecting blocks 11 placed below the pusher clamping assembly 5 are arranged on the inner wall of the shell body 1, a mounting plate 12 is arranged between the plurality of connecting blocks 11 on the side away from the inner wall of the shell body 1, a spray assembly 13 for spraying quenching liquid on the woodworking drill bit placed at the bottom of the placement tray 15 is arranged on the top of the mounting plate 12, a filter screen 17 inclined downward and placed below the spray assembly 13 is arranged inside the shell body 1, a conveying assembly 2 for conveying the quenching liquid below the filter screen 17 to the inside of the spray assembly 13 is arranged at the lower part of the other side of the shell body 1, and a plurality of fixing sleeves 151 for placing woodworking drill bits are arranged at the bottom of the placement tray 15. When heat-treating a woodworking drill bit, the design first connects a plurality of woodworking drill bits to the fixing sleeve 151, places the woodworking drill bits, and then places the placement tray 15 prepared in advance with the woodworking drill bits on the material pushing and clamping assembly 5, and then uses the material pushing and clamping assembly 5 to send the placement tray 15 to the inside of the housing 1, and sends the quenching liquid to the inside of the spray assembly 13 through the conveying assembly 2 and sprays it to a plurality of woodworking drill bits, thereby heat-treating the woodworking drill bits. When heat-treating a woodworking drill bit, the woodworking drill bit to be heat-treated can be connected to the fixing sleeve 151 at the bottom of the placement tray 15 in advance through another placement tray 15, thereby saving the installation and placement time of the woodworking drill bit and greatly improving the heat treatment efficiency of the woodworking drill bit. Since the filter 17 is provided to filter impurities, it can be prevented that after the quenching liquid is sprayed on the woodworking drill bit, the impurities follow the quenching liquid and flow back to the inside of the spraying component 13 through the conveying component 2 and are conveyed to the woodworking drill bit, causing damage to the woodworking drill bit, thereby improving the heat treatment quality of the woodworking drill bit.

[0020] Reference Figure 2 , Figure 5 and Figure 8The material pushing and clamping assembly 5 includes a push plate 51 arranged inside the guide groove 4, a placement hole 52 that penetrates and matches the placement plate 15 is opened on the top of the push plate 51, a pair of avoidance grooves 57 that are connected to the placement hole 52 are symmetrically opened inside the push plate 51, and an arc-shaped clamping plate 56 for clamping the placement plate 15 is arranged inside the pair of avoidance grooves 57. A pair of baffles 55 arranged below the avoidance grooves 57 are symmetrically arranged on the inner wall of the push plate 51. A pair of clamping electric push rods 53 respectively connected to the pair of arc-shaped clamping plates 56 are arranged inside the push plate 51, and a limit plate 54 is arranged on the side of the push plate 51 away from the shell 1. The limit plate 54 is away from the shell 1. A force-applying groove 541 is provided on one side. The design places the placement plate 15 with the woodworking drill bit inside the placement hole 52, limits the placement plate 15 under the action of the baffle 55, and then enables a pair of clamping electric push rods 53 to work and drive a pair of arc-shaped clamping plates 56 to move toward each other along the avoidance groove 57 to clamp the opposite sides of the placement plate 15, thereby facilitating the clamping of the placement plate 15 with the woodworking drill bit, and then applies force to the limiting plate 54 to push the push plate 51 to move along the guide groove 4, thereby sending the placement plate 15 to the inside of the shell 1, wherein the bottom of the wood drill bit is higher than the lower end surface of the push plate 51 to avoid interference.

[0021] Reference Figure 5 , Figure 6 and Figure 7 A pair of guide columns 14 are symmetrically arranged inside the shell 1 and are placed below the clamping electric push rod 53. A pair of guide holes 20 matching the guide columns 14 are opened at positions corresponding to the guide columns 14 inside the push plate 51. This design uses the guide columns 14 and the guide holes 20 to facilitate the movement of the guide holes 20 on the push plate 51 along the side walls of the guide columns 14, thereby improving the stability of the lateral movement of the push plate 51. The direction in which the guide columns 14 are set is parallel to the direction in which the push plate 51 moves, and at the same time supports the push plate 51 in the vertical direction, thereby improving the stability of the spray assembly 13 in spraying the placement plate 15.

[0022] Reference Figure 2 , Figure 4 and Figure 6 The spray assembly 13 includes a spray plate 131 disposed on the top of the mounting plate 12, a hollow groove 132 is provided inside the spray plate 131, a plurality of nozzles 133 connected to the hollow groove 132 are provided on the top of the spray plate 131, and the conveying assembly 2 is connected to the hollow groove 132; A pair of positioning posts 551 are symmetrically arranged on the top of the baffle 55, and a pair of positioning holes matching the positioning posts 551 are opened at the positions corresponding to the positioning posts 551 at the bottom of the placement tray 15. The multiple nozzles 133 correspond one-to-one to the multiple fixing sleeves 151. The design conveys the quenching liquid under the filter screen 17 to the inside of the hollow groove 132 through the conveying component 2 and sprays it out from the multiple nozzles 133, and positions the connection between the placement tray 15 and the baffle 55 by connecting the positioning posts 551 with the positioning holes, so that the multiple nozzles 133 correspond one-to-one to the multiple fixing sleeves 151, so that the nozzles 133 can accurately spray the quenching liquid on the woodworking drill bit on the fixing sleeve 151, thereby performing heat treatment operations.

[0023] Reference Figure 2 The conveying assembly 2 includes a pump body 22 arranged on the side wall of the shell 1 and placed under the mounting plate 12. The end of the pump body 22 away from the shell 1 is provided with a guide pipe 21 placed under the filter screen 17 and connected to the shell 1. The other end of the pump body 22 is provided with an L-shaped conveying pipe 23 placed above the filter screen 17. The side wall of the L-shaped conveying pipe 23 is provided with a guide pipe 24 that penetrates the mounting plate 12 and is connected to the hollow groove 132. This design uses the pump body 22 in the conveying assembly 2 to work so that the quenching liquid is conveyed to the inside of the hollow groove 132 through the guide pipe 21, the L-shaped conveying pipe 23 and the guide pipe 24 and sprayed from the nozzle 133. Since the guide pipe 21 is placed under the filter screen 17, it is ensured that there are no impurities in the quenching liquid conveyed to the inside of the hollow groove 132, thereby preventing impurities on the woodworking drill from entering the nozzle 133.

[0024] Reference Figure 2 and Figure 6 , a plurality of connection blocks 11 are distributed at 90 degrees on the side wall of the mounting plate 12, and a slide groove 10 is vertically opened at a position on the inner wall of the housing 1 corresponding to the connection block 11; A lifting drive assembly 3 for driving the placement plate 15 to move in the vertical direction is provided on the top of the shell 1. The lifting drive assembly 3 includes a connecting column 32 arranged on the top of the connecting block 11. A lifting electric push rod 31 connected to the connecting column 32 is provided on the top of the shell 1. This design drives the connecting column 32 to move in the vertical direction through the operation of the lifting electric push rod 31. The movement of the connecting column 32 drives the connecting block 11 to move inside the slide groove 10. The movement of the connecting block 11 drives the mounting plate 12 to move in the vertical direction. The movement of the mounting plate 12 in the vertical direction drives the spray plate 131 to move in the vertical direction, so that the distance between the nozzle 133 and the woodworking drill bit can be adjusted. During the heat treatment process, if the nozzle 133 is too close to the woodworking drill bit, the water spray range may be too concentrated, resulting in uneven temperature distribution on the surface of the woodworking drill bit. If the distance is too far, the water spray range may be too dispersed, and an ideal temperature distribution cannot be formed. By adjusting the distance between the nozzle 133 and the woodworking drill bit, the temperature distribution on the surface of the woodworking drill bit can be optimized to make it more uniform, thereby improving the overall performance of the woodworking drill bit.

[0025] Reference Figure 2 and Figure 3 A piston 18 is arranged on the top of the L-shaped delivery pipe 23 and is placed on the inner wall of the guide pipe 24. A through hole 19 is opened on the top of the piston 18 to connect the L-shaped delivery pipe 23 with the guide pipe 24. This design facilitates the sealing between the L-shaped delivery pipe 23 and the guide pipe 24 to be ensured under the action of the piston 18 when the guide pipe 24 moves in the vertical direction following the mounting plate 12, and the quenching liquid is transported through the through hole 19, thereby improving the rationality of the design.

[0026] Reference Figure 1 and Figure 2 The side wall of the shell 1 is provided with a blocking plate 72 placed above the filter screen 17, and the side wall of the shell 1 is provided with a sealing plate 7 connected to the blocking plate 72. The side wall of the sealing plate 7 is provided with a force applying handle 71. The blocking plate 72 is placed above the lower end of the filter screen 17. The vertical cross-sectional area of ​​the sealing plate 7 is larger than the vertical cross-sectional area of ​​the blocking plate 72. This design facilitates the accumulation of impurities at the blocking plate 72 along the inclined filter screen 17 without affecting the filtering effect of the impurities. In order to improve the stability of the connection between the sealing plate 7 and the shell 1, a butterfly bolt can be set between the sealing plate 7 and the shell 1.

[0027] Reference Figure 2 A connecting groove 16 is provided inside the shell 1 and is placed above the filter screen 17. A sealing groove 9 connected to the connecting groove 16 is provided on the side wall of the shell 1. The sealing plate 7 matches the sealing groove 9, and the blocking plate 72 matches the connecting groove 16. This design improves the sealing performance of the connection and facilitates the removal of the sealing plate 7 and the blocking plate 72, thereby facilitating the cleaning of impurities on the filter screen 17.

[0028] Reference Figure 1 The side wall of the shell 1 is provided with a liquid inlet pipe 6 placed above the filter screen 17, and the side wall of the liquid inlet pipe 6 is provided with a liquid inlet valve 61. The side wall of the shell 1 is provided with a liquid outlet pipe 8 placed below the filter screen 17, and the side wall of the liquid outlet pipe 8 is provided with a liquid outlet valve 81, which improves the rationality of the design.

[0029] Reference Figure 1-Figure 8 As an embodiment of the present invention: when a woodworking drill bit needs to be heat treated, the staff first prepares in advance to connect a plurality of woodworking drill bits with the fixing sleeve 151, places the woodworking drill bits, and then places the prepared placement tray 15 with the woodworking drill bits inside the placement hole 52 in the push clamping assembly 5, and limits the placement tray 15 under the action of the baffle 55, and at the same time connects the positioning hole on the placement tray 15 with the positioning column 551 on the baffle 55 to locate the position of the woodworking drill bit, and then makes a pair of clamping electric push rods 53 work to drive a pair of arc clamping plates 5 6 moves toward the side approaching each other along the avoidance groove 57 to clamp the two opposite sides of the placement plate 15, so as to facilitate the clamping of the placement plate 15 on which the woodworking drill bit is placed, and then the limiting plate 54 is forced to push the push plate 51 to move along the guide groove 4 under the guidance of the guide column 14 and the guide hole 20, so as to deliver the placement plate 15 to the inside of the housing 1, and then the pump body 22 in the conveying assembly 2 is operated, so as to deliver the quenching liquid to the inside of the hollow groove 132 through the guide pipe 21, the L-shaped conveying pipe 23 and the guide pipe 24, and spray it from the nozzle 133 to perform heat treatment operation on the woodworking drill bit. Since the guide tube 21 is placed below the filter 17, it ensures that there are no impurities in the quenching liquid transported to the inside of the hollow groove 132, preventing impurities on the woodworking drill from entering the nozzle 133, and thus preventing the impurities from following the quenching liquid after the woodworking drill is sprayed with quenching liquid. The quenching liquid flows back to the inside of the spraying assembly 13 through the conveying assembly 2 and is transported to the woodworking drill, causing damage to the woodworking drill, thereby improving the heat treatment quality of the woodworking drill. When the woodworking drill is heat treated, the woodworking drill to be heat treated can be connected to the fixing sleeve 151 at the bottom of the placement tray 15 in advance by using another placement tray 15, thereby saving the installation and placement time of the woodworking drill and greatly improving the heat treatment efficiency of the woodworking drill.

[0030] When it is necessary to adjust the distance between the nozzle 133 and the woodworking drill bit, the lifting electric push rod 31 is operated to drive the connecting column 32 to move in the vertical direction. The connection column 32 moves to drive the connecting block 11 to move inside the slide groove 10. The connection block 11 moves to drive the mounting plate 12 to move in the vertical direction. The mounting plate 12 moves in the vertical direction to drive the spray plate 131 to move in the vertical direction. The movement of the spray plate 131 drives the guide tube 24 to move in the vertical direction along the side wall of the piston 18. Under the action of the piston 18, the sealing between the L-shaped delivery pipe 23 and the guide pipe 24 is guaranteed and the quenching liquid is delivered through the through hole 19, so that the distance from the nozzle 133 to the woodworking drill bit can be adjusted and the delivery of the quenching liquid is guaranteed.

[0031] When it is necessary to deal with impurities, force is applied to the force-applying handle 71 to drive the sealing cover plate to disengage from the sealing groove 9, and drive the blocking plate 72 to disengage from the connecting groove 16, so as to facilitate the removal of impurities from the connecting groove 16 and the sealing groove 9, thereby facilitating the cleaning operation of the impurities. Since the filter screen 17 is arranged at an angle, the impurities can flow out of the connecting groove 16 along its inclined surface. In order to facilitate the cleaning of impurities, a vibration motor can be arranged on the shell 1 as a prior art, so as to facilitate the impurities to move downward along the surface of the filter screen 17.
