Description

Technical Field

[0001] This application relates to the technical field of zinc-nickel infiltration layer treatment, and particularly relates to a tooling for zinc-nickel infiltration layer treatment. Background Art

[0002] Performing zinc-nickel infiltration layer treatment on the surface of a workpiece can form an alloy layer, thereby achieving the purpose of anti-corrosion of the workpiece. The zinc-nickel infiltration layer treatment includes an infiltration layer process. The technological process is to place the workpiece to be infiltrated into the tooling, then place the tooling into the furnace liner filled with the infiltration agent, and install it on the furnace for rotary heating. Under certain conditions, an alloy anti-corrosion layer gradually forms on the surface of the workpiece.

[0003] Currently, the tooling used for zinc-nickel infiltration layer treatment has an opening facing upwards. After the infiltration layer process, the workpiece needs to be poured out of the tooling. During this process, it is necessary to perform an operation of flipping the tooling for discharging materials. When the workpiece is flipped with the tooling to a certain extent, it will suddenly rush out of the tooling, resulting in a large height drop when the workpiece falls out, seriously damaging the alloy anti-corrosion layer on the surface. Utility Model Content

[0004] In view of this, this application provides a tooling for zinc-nickel infiltration layer treatment, which is beneficial to reducing the damage to the alloy anti-corrosion layer on the surface of the workpiece during discharging.

[0005] An embodiment of this application provides a tooling for zinc-nickel infiltration layer treatment, including a main body, a cover body, a connecting member, a first limiting member, and a second limiting member. The main body has a receiving cavity for accommodating the workpiece and is provided with a first through hole, and the first through hole communicates with the receiving cavity; the cover body is connected to the main body to cover the receiving cavity; the connecting member is movably connected and protrudes from the main body and the cover body; the first limiting member is arranged on the connecting member and is used to support the main body; the second limiting member is detachably arranged on the connecting member, and the first limiting member and the second limiting member cooperate to limit the relative movement of the main body and the cover body with respect to the connecting member.

[0006] The above-mentioned main body is provided with a first through hole communicating with the receiving cavity. When performing the infiltration layer process, the first through hole is beneficial for the infiltration agent to enter the receiving cavity and react on the surface of the workpiece to form an alloy anti-corrosion layer. The cover body is connected to the main body to cover the receiving cavity. Therefore, during the process of flipping the whole tooling, the workpiece inside will not directly rush out of the receiving cavity, but is transferred from the receiving cavity to the cover body. Subsequently, the second limiting member is disassembled from the connecting member, whereby it is convenient to lift and pull out components such as the connecting member and the main body, and the workpiece will automatically remain on the cover body. At this time, the cover body can play a role in supporting the workpiece. Finally, the cover body is pulled out from below the workpiece, thereby completing the discharging. In this way, changing the discharging method from the original flipping and discharging to first transferring the workpiece from the receiving cavity to the cover body and then pulling out the cover body to complete the discharging is beneficial to reducing the drop of the workpiece during discharging, thereby reducing the damage to the alloy anti-corrosion layer on the surface of the workpiece and ensuring the integrity of the alloy anti-corrosion layer on the surface of the workpiece.

[0007] In some embodiments, the main body includes a bottom plate and side plates. The side plates are connected to the bottom plate and enclose a receiving cavity with the bottom plate. Both the bottom plate and the side plates are provided with first through holes.

[0008] In the tooling for zinc-nickel infiltration layer treatment in the above embodiments, when the infiltration layer process is carried out, the first through holes of the bottom plate and the side plates are beneficial for the infiltrant to enter the receiving cavity better from multiple directions, and at the same time are beneficial for the infiltrant after the reaction and the excess infiltrant to flow out of the receiving cavity, reducing the accumulation of the infiltrant in the receiving cavity.

[0009] In some embodiments, the main body further includes a first reinforcing member and a second reinforcing member. The first reinforcing member is disposed around the connection between the inner side plate of the receiving cavity and the bottom plate, and the second reinforcing member is connected to the outer periphery of the side plate. The length direction of the second reinforcing member is parallel to the side plate.

[0010] In the tooling for zinc-nickel infiltration layer treatment in the above embodiments, when the bottom plate and the side plates are relatively thin, the first reinforcing member is beneficial for improving the stability of the connection between the side plate and the bottom plate, and the second reinforcing member is beneficial for enhancing the anti-deformation ability of the side plate.

[0011] In some embodiments, the main body further includes a first sleeve, which is connected to the bottom plate and disposed in the receiving cavity. The first sleeve is movably sleeved on the connecting member, and the length direction of the first sleeve is perpendicular to the bottom plate.

[0012] In the tooling for zinc-nickel infiltration layer treatment in the above embodiments, when the bottom plate is relatively thin, the first sleeve is movably sleeved on the connecting member, which is beneficial for reducing the possibility of the main body tilting relative to the connecting member, thereby being beneficial for the tooling to be more stable during the infiltration layer process.

[0013] In some embodiments, the main body further includes a third reinforcing member, which is disposed around the connection between the first sleeve and the bottom plate in the receiving cavity.

[0014] In the tooling for zinc-nickel infiltration layer treatment in the above embodiments, it is beneficial for improving the stability of the connection between the first sleeve and the bottom plate, and further reducing the possibility of the main body tilting relative to the connecting member.

[0015] In some embodiments, the first sleeve protrudes from the bottom plate in the direction away from the receiving cavity. The main body further includes a fourth reinforcing member, which extends radially outward from the protruding part of the first sleeve and is connected to the bottom plate.

[0016] In the tooling for zinc-nickel infiltration layer treatment in the above embodiments, when the bottom plate is relatively thin, the fourth reinforcing member and the first sleeve cooperate to support the bottom plate, which is beneficial for enhancing the anti-deformation ability of the bottom plate.

[0017] In some embodiments, the cover body includes a cover plate and a second sleeve. The second sleeve is connected to the cover plate and is movably sleeved on the connecting member. The length direction of the second sleeve is perpendicular to the cover plate.

[0018] In the tooling for zinc-nickel diffusion treatment of the above embodiment, when the cover plate is relatively thin, the second sleeve is movably sleeved on the connecting piece, which is helpful to reduce the possibility of the cover body being skewed relative to the connecting piece, thereby making the tooling more stable during the diffusion process.

[0019] In some embodiments, the second sleeve protrudes from the cover plate in a direction away from the accommodating cavity, and the cover body further includes a fifth reinforcement member, which extends radially outward from the protruding portion of the second sleeve and connects to the cover plate.

[0020] In the tooling for zinc-nickel layer treatment of the above embodiment, when the workpiece is transferred from the accommodating cavity to the cover body, the fifth reinforcement member cooperates with the second sleeve to form support for the cover plate, which is beneficial for the cover body to carry more workpieces.

[0021] In some embodiments, the cover body is provided with a second through hole, and the second through hole is connected to the accommodating cavity.

[0022] In the tooling for zinc-nickel diffusion layer treatment of the above-mentioned embodiment, when the diffusion layer process is carried out, the first through holes of the main body and the cover body are conducive to the better entry of the diffusing agent into the accommodating cavity; when the workpiece is transferred from the accommodating cavity to the cover body, the remaining diffusing agent in the accommodating cavity may be transferred to the cover body, and the first through hole of the cover body is conducive to further screening out the remaining diffusing agent.

[0023] In some embodiments, the tooling for zinc-nickel diffusion layer treatment further includes a stop structure, which is connected to the main body and extends beyond an end of the connector that is away from the cover body.

[0024] In the tooling for zinc-nickel diffusion layer treatment in the above-mentioned embodiment, the stop structure is helpful for protecting the connecting piece, thereby reducing the risk of the second limit piece being detached from the connecting piece due to mutual friction and extrusion of multiple sets of tooling in the furnace.

The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0075] Currently, the tooling used for zinc-nickel infiltration treatment of workpieces has an opening facing upwards. In the subsequent processes after the infiltration layer is completed, the workpieces in the tooling need to be poured out and placed on a vibrating screening device to remove the infiltrant on the surface of the workpieces. Since the height of the tooling ranges from 300 mm to 500 mm and the diameter ranges from 900 mm to 1100 mm, during the process of tipping the tooling for pouring, the workpieces inside will gradually tilt with the tooling. When the tilt reaches about 45 degrees, the workpieces will suddenly start to rush out of the tooling. In particular, the drop of some workpieces when rushing out can reach about 1 meter. Such a high drop will cause serious damage to the alloy anti-corrosion layer on the surface of the workpieces, resulting in a reduction in the anti-corrosion effect of the workpieces and unable to ensure the anti-corrosion quality of workpieces with high requirements.

[0076] Based on the above situation, an embodiment of the present application discloses a tooling for zinc-nickel infiltration treatment, including a main body, a cover body, a connecting member, a first limiting member, and a second limiting member. The main body has a receiving cavity for receiving workpieces and is provided with a first through hole, and the first through hole communicates with the receiving cavity; the cover body is connected to the main body to cover the receiving cavity; the connecting member is movably connected and protrudes from the main body and the cover body; the first limiting member is disposed on the connecting member and is used to support the main body; the second limiting member is detachably disposed on the connecting member, and the first limiting member and the second limiting member cooperate to limit the activities of the main body and the cover body relative to the connecting member.

[0077] The above-mentioned main body is provided with a first through hole communicating with the receiving cavity. When performing the infiltration layer process, the first through hole is beneficial for the infiltrant to enter the receiving cavity and react on the surface of the workpieces to form an alloy anti-corrosion layer. The cover body is connected to the main body to cover the receiving cavity. Therefore, during the process of tipping the whole tooling, the workpieces inside will not directly rush out of the receiving cavity, but transfer from the receiving cavity to the cover body. Subsequently, the second limiting member is disassembled from the connecting member, whereby the connecting member, the main body and other components can be conveniently lifted and pulled out, while the workpieces will automatically remain on the cover body. At this time, the cover body can play a role in supporting the workpieces. Finally, the cover body is pulled out from under the workpieces, thus completing the discharging. In this way, the discharging method is changed from the original tipping and pouring to first transferring the workpieces from the receiving cavity to the cover body and then pulling out the cover body to complete the discharging, which is beneficial to reducing the drop of the workpieces during discharging, thereby reducing the damage to the alloy anti-corrosion layer on the surface of the workpieces and ensuring the integrity of the alloy anti-corrosion layer on the surface of the workpieces.

[0078] The following will describe some embodiments of the present application in conjunction with the drawings. For the convenience of description, the tooling for zinc-nickel infiltration treatment will be simply referred to as tooling hereinafter. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0079] Please refer to Figures 1 to 4, the tooling 10 includes a main body 11, a cover 12, a connecting member 13, a first limiting member 14 and a second limiting member 15. The main body 11 has a receiving cavity 101 for receiving a workpiece and is provided with a first through hole 102, and the first through hole 102 communicates with the receiving cavity 101; the cover 12 is connected to the main body 11 to cover the receiving cavity 101; the connecting member 13 is movably connected and protrudes from the main body 11 and the cover 12; the first limiting member 14 is disposed on the connecting member 13 and is used to support the main body 11; the second limiting member 15 is detachably disposed on the connecting member 13, and the first limiting member 14 and the second limiting member 15 cooperate to limit the relative movement of the main body 11 and the cover 12 with respect to the connecting member 13.

[0080] When performing the infiltration layer process, first place the workpiece in the tooling 10, then install the tooling 10 into the furnace filled with the infiltrant through the connecting member 13, and then rotate the tooling 10 for uniform heating. During this process, the infiltrant can enter the receiving cavity 101 through the first through hole 102 on the main body 11, contact the workpiece and react on the surface of the workpiece to form an alloy anti-corrosion layer; when the infiltration layer process is completed, the tooling 10 can be taken out of the furnace and the tooling 10 is turned over as a whole and placed on the operating table 20. At this time, along the direction of gravity, the connecting member 13 is successively provided with a first limiting member 14, a main body 11, a cover 12 and a second limiting member 15 (as Figure 2 shown), and the workpiece is transferred from the receiving cavity 101 to the cover 12, and the cover 12 can play a role in supporting the workpiece. After the transfer is completed, disassemble the second limiting member 15 from the connecting member 13, which is beneficial to removing the connecting member 13 and the main body 11 to take out the workpiece. In this way, it is beneficial to reduce the damage to the alloy anti-corrosion layer on the surface of the workpiece during pouring.

[0081] In some embodiments, the connecting member 13 can be movably connected to multiple groups of the main body 11 and the cover 12. For example, refer to Figure 1 and Figure 2 , the figure shows a situation where the connecting member 13 is movably connected to four groups of the main body 11 and the cover 12, and the first limiting member 14 and the second limiting member 15 cooperate to limit the relative movement of the four groups of the main body 11 and the cover 12 with respect to the connecting member 13.

[0082] In some embodiments, please refer to Figure 3 and Figure 4 , the main body 11 includes a bottom plate 111 and a side plate 112. The side plate 112 is connected to the bottom plate 111 and encloses the receiving cavity 101 with the bottom plate 111. Both the bottom plate 111 and the side plate 112 are provided with the first through hole 102. In this way, when performing the infiltration layer process, the first through holes 102 on the bottom plate 111 and the side plate 112 are beneficial for the infiltrant to enter the receiving cavity 101 better from multiple directions, and at the same time beneficial for the reacted infiltrant and the excess infiltrant to flow out of the receiving cavity 101, reducing the accumulation of the infiltrant in the receiving cavity 101.

[0083] In some embodiments, the bottom plate 111 is cut from a punched steel plate with a thickness of 10 mm, and the side plate 112 is cut from a punched steel plate with a thickness of 6 mm and then enclosed around the bottom plate 111. The diameter of the first through hole 102 is 16 mm.

[0084] In some embodiments, please refer to Figure 3 and Figure 4 , the main body 11 further includes a first reinforcing member 113 and a second reinforcing member 114. The first reinforcing member 113 is disposed around the connection between the inner side plate 112 and the bottom plate 111 of the accommodation cavity 101, and the second reinforcing member 114 is connected to the outer periphery of the side plate 112. The length direction of the second reinforcing member 114 is parallel to the side plate 112. Thus, when the bottom plate 111 and the side plate 112 are relatively thin, the first reinforcing member 113 is beneficial to improving the connection stability between the side plate 112 and the bottom plate 111, and the second reinforcing member 114 is beneficial to enhancing the anti-deformation ability of the side plate 112.

[0085] In some embodiments, the first reinforcing member 113 is a ring-shaped steel bar, and the second reinforcing member 114 is a straight steel bar.

[0086] In some embodiments, the number of the second reinforcing members 114 can be multiple, such as 2, 3, 4, 6, 12 or more. The multiple second reinforcing members 114 are evenly distributed on the outer periphery of the side plate 112.

[0087] In some embodiments, please refer to Figure 3 and Figure 4 , the main body 11 further includes a first fixing member 115 and a second fixing member 116. The first fixing member 115 is disposed at one end of the side plate 112 close to the bottom plate 111, and the second fixing member 116 is disposed at one end of the side plate 112 far from the bottom plate 111.

[0088] In some embodiments, both the first fixing member 115 and the second fixing member 116 protrude outward along the outer periphery of the side plate 112, and both ends of the second reinforcing member 114 are respectively connected to the first fixing member 115 and the second fixing member 116. Thus, the cooperation of the second reinforcing member 114 with the first fixing member 115 and the second fixing member 116 is beneficial to further enhancing the anti-deformation ability of the side plate 112.

[0089] In some embodiments, the first fixing member 115 protrudes inward along the outer periphery of the side plate 112. At this time, the first fixing member 115 connects the bottom plate 111 and the side plate 112. Thus, the cooperation of the first fixing member 115 with the first reinforcing member 113 is beneficial to further improving the connection stability between the side plate 112 and the bottom plate 111.

[0090] In some embodiments, the second fixing member 116 protrudes inwards along the outer periphery of the side plate 112. The number of the first reinforcing members 113 is two, and the additional first reinforcing members 113 surround the connection between the inner side plate 112 of the accommodation cavity 101 and the second fixing member 116. In this way, it is beneficial to improve the stability of the connection between the side plate 112 and the second fixing member 116.

[0091] In some embodiments, the first fixing member 115 and the second fixing member 116 are flange plates, and the two ends of the second reinforcing member 114 are respectively welded to the first fixing member 115 and the second fixing member 116.

[0092] In some embodiments, please refer to Figure 3 and Figure 4 , the main body 11 further includes a first sleeve 117. The first sleeve 117 is connected to the bottom plate 111 and is disposed in the accommodation cavity 101. The first sleeve 117 is movably sleeved on the connecting member 13. The length direction of the first sleeve 117 is perpendicular to the bottom plate 111. In this way, when the bottom plate 111 is relatively thin, by movably sleeving the first sleeve 117 on the connecting member 13, it is beneficial to reduce the possibility that the main body 11 is skewed relative to the connecting member 13, so that the tooling 10 is more stable when performing the infiltration process.

[0093] In some embodiments, please refer to Figure 3 and Figure 4 , the main body 11 further includes a third reinforcing member 118. The third reinforcing member 118 surrounds the connection between the first sleeve 117 and the bottom plate 111 in the accommodation cavity 101. In this way, it is beneficial to improve the stability of the connection between the first sleeve 117 and the bottom plate 111, and further reduce the possibility that the main body 11 is skewed relative to the connecting member 13.

[0094] In some embodiments, the third reinforcing member 118 is a ring-shaped steel bar.

[0095] In some embodiments, please refer to Figure 4 , the first sleeve 117 protrudes from the bottom plate 111 in the direction away from the accommodation cavity 101. The main body 11 further includes a fourth reinforcing member 119. The fourth reinforcing member 119 extends radially outwards along the protruding part of the first sleeve 117 and is connected to the bottom plate 111. In this way, when the bottom plate 111 is relatively thin, the fourth reinforcing member 119 and the first sleeve 117 can cooperate to support the bottom plate 111, which is beneficial to enhancing the anti-deformation ability of the bottom plate 111.

[0096] In some embodiments, the fourth reinforcing member 119 extends and is connected to the first fixing member 115. In this way, it is beneficial to improve the stability of the connection between the fourth reinforcing member 119 and the bottom plate 111.

[0097] In some embodiments, the number of the fourth reinforcing members 119 may be plural, such as 2, 3, 4, 6, 12 or more. The plural fourth reinforcing members 119 are evenly distributed on the bottom plate 111. In other words, the plural fourth reinforcing members 119 are evenly distributed radially on the bottom plate 111. Thus, it is beneficial to make the structural strength of the bottom plate 111 higher and more uniform, so that the main body 11 can carry more workpieces.

[0098] In some embodiments, a first abutting member 103 is provided between two adjacent fourth reinforcing members 119. Thus, the cooperation of the fourth reinforcing member 119 and the first abutting member 103 is beneficial to further enhance the anti-deformation ability of the bottom plate 111.

[0099] In some embodiments, the fourth reinforcing member 119 and the first abutting member 103 are straight steel bars.

[0100] In some embodiments, please refer to Figure 5 and Figure 6 , the cover 12 includes a cover plate 121 and a second sleeve 122. The second sleeve 122 is connected to the cover plate 121 and movably sleeved on the connecting member 13. The length direction of the second sleeve 122 is perpendicular to the cover plate 121. Thus, when the cover plate 121 is relatively thin, by movably sleeving the second sleeve 122 on the connecting member 13, it is beneficial to reduce the possibility of the cover 12 tilting relative to the connecting member 13, so that the tooling 10 is more stable during the case-hardening process.

[0101] In some embodiments, the second sleeve 122 protrudes from the cover plate 121 in a direction away from the accommodating cavity 101. The cover 12 further includes a fifth reinforcing member 123. The fifth reinforcing member 123 extends radially outward along the protruding part of the second sleeve 122 and is connected to the cover plate 121. Thus, when the workpiece is transferred from the accommodating cavity 101 to the cover 12, the cooperation of the fifth reinforcing member 123 and the second sleeve 122 can support the cover plate 121, which is beneficial to the cover 12 carrying more workpieces.

[0102] In some embodiments, the number of the fifth reinforcing members 123 may be plural, such as 2, 3, 4, 6, 12 or more. The plural fifth reinforcing members 123 are evenly distributed on the cover plate 121. In other words, the plural fifth reinforcing members 123 are evenly distributed radially on the cover plate 121.

[0103] In some embodiments, a second abutting member 104 is provided between two adjacent fifth reinforcing members 123. Thus, the cooperation of the fifth reinforcing member 123 and the second abutting member 104 is beneficial to enhance the anti-deformation ability of the cover plate 121.

[0104] In some embodiments, the cover body 12 further includes a plurality of sixth reinforcing members 124, and the plurality of sixth reinforcing members 124 are evenly distributed on the periphery of the cover plate 121.

[0105] In some embodiments, the cover body 12 further includes a third fixing member 125, and the third fixing member 125 connects the plurality of sixth reinforcing members 124.

[0106] In some embodiments, the fifth reinforcing member 123, the sixth reinforcing member 124, and the second abutting member 104 are straight reinforcing bars. In some embodiments, the third fixing member 125 is a flange.

[0107] In some embodiments, the cover body 12 is provided with a second through hole 105. Thus, when performing the infiltration layer process, the first through hole 102 of the main body 11 and the second through hole 105 of the cover body 12 are beneficial for the infiltrant to better enter the accommodation cavity 101; when the workpiece is transferred from the accommodation cavity 101 to the cover body 12, the remaining infiltrant in the accommodation cavity 101 may be transferred to the cover body 12 accordingly, and the second through hole 105 of the cover body 12 is beneficial for further screening out the remaining infiltrant.

[0108] In some embodiments, the cover plate 121 of the cover body 12 is provided with a second through hole 105.

[0109] In some embodiments, the connecting member 13 is provided with a mounting groove (not shown in the figure), and the second limiting member 15 is removably disposed in the mounting groove. Thus, the second limiting member 15 being disposed in the mounting groove is beneficial for the second limiting member 15 and the connecting member 13 to form a locking, thereby being beneficial for improving the stability of the cooperation between the first limiting member 14 and the second limiting member 15 to limit the main body 11 and the cover body 12.

[0110] In some embodiments, please refer to Figure 7 , the connecting member 13 is provided with a first fixing hole 131, the second limiting member 15 is provided with a second fixing hole 151, and a fixing member (not shown in the figure) passes through the first fixing hole 131 and the second fixing hole 151 to fix the connecting member 13 and the second limiting member 15.

[0111] In some embodiments, please refer to Figure 7 , the connecting member 13 is provided with a hanging hole 132, and the hanging hole 132 is used to provide a grasping position for the tooling 10 to be sent into the furnace or taken out of the furnace.

[0112] In some embodiments, the connecting member 13 is generally rod-shaped, the first limiting member 14 is generally rib-shaped, and the second limiting member 15 is generally wedge-shaped. In some embodiments, the fixing member is a wire or a bolt, etc.

[0113] In some embodiments, multiple sets of tooling 10 can be installed in the furnace simultaneously for the carburizing layer process. However, there may be a situation where friction between the toolings 10 affects the structural stability of the tooling 10. For this reason, some embodiments of the present application provide solutions.

[0114] In some embodiments, referring to Figure 1 and Figure 2 , the tooling 10 further includes a stop structure 16. The stop structure 16 is connected to the main body 11 and extends beyond one end of the connecting member 13 facing away from the cover body 12. In this way, the stop structure 16 is beneficial to protecting the connecting member 13 and reducing the risk that the second limiting member 15 is disengaged from the connecting member 13 due to mutual friction and extrusion of multiple sets of tooling 10 in the furnace.

[0115] In some embodiments, the stop structure 16 includes a support member 161, a first stop member 162, and a second stop member 163. The support member 161 is connected to the main body 11, extends in a direction away from the accommodation cavity 101, and extends beyond one end of the connecting member 13 facing away from the cover body 12. The first stop member 162 and the second stop member 163 are sequentially arranged on the support member 161 along the extending direction of the support member 161. Refer to Figure 1 . Let the distance between one end of the connecting member 13 facing away from the cover body 12 and the main body 11 be a first distance h1, and the distance between the first stop member 162 and the main body 11 be a second distance h2. The second distance h2 is greater than the first distance h1.

[0116] In some embodiments, the support member 161 is a connecting rod, and the first stop member 162 and the second stop member 163 are flange plates.

[0117] The following takes the tooling 10 including four groups of main bodies 11 and cover bodies 12 as an example to illustrate the use process and beneficial effects of the tooling 10:

[0118] First, load the workpiece into each main body 11, then sleeved the first main body 11 onto the connecting member 13, and sleeved the first cover body 12 onto the connecting member 13 to cover the first main body 11. Then, sequentially sleeve the other main bodies 11 and cover bodies 12. After all the main bodies 11 and cover bodies 12 are sleeved, install the second limiting member 15 onto the connecting member 13 to cooperate with the first limiting member 14 to limit the movement of the four groups of main bodies 11 and cover bodies 12 relative to the connecting member 13. At this point, the loading and the assembly of the tooling 10 are completed, and the tooling 10 is installed in the furnace through the connecting member 13 for the carburizing layer process.

[0119] After the carburizing layer process is completed, take out the tooling 10 in a horizontal state (i.e., the state where the connecting member 13 is horizontal), then hang the hanging hole 132 at one end of the connecting member 13 close to the second limiting member 15, and turn the tooling 10 to the state where the cover body 12 is below the main body 11. Then, keep this state and place the tooling 10 on the operating table 20, asFigure 2 As shown. Remove the second limiting member 15 from the connecting member 13, and then take out the connecting member 13 together with the first limiting member 14 from bottom to top. At this time, the four groups of main bodies 11 and the cover bodies 12 are independent of each other. Lift out each group of main bodies 11 and cover bodies 12 in sequence from top to bottom and place them on the corresponding receiving platforms. Each time when lifting out, the cover body 12 and the main body 11 above it are regarded as a whole. Subsequently, take out the main body 11 from bottom to top. At this time, the workpiece has been transferred from the accommodating cavity 101 of the main body 11 to the cover body 12. Finally, pull out the cover body 12 from the receiving platform, then the workpiece can directly stay on the receiving platform of the next process. In this way, it is beneficial to reduce the damage to the alloy anti-corrosion layer on the surface of the workpiece during pouring.

[0120] In addition, those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as it is within the substantial scope of the present application, the appropriate changes and variations made to the above embodiments fall within the scope disclosed in the present application.
