Description

Technical Field

[0001] This application relates to the field of metal processing, and in particular to a steam treatment apparatus for metal parts. Background Technology

[0002] Metal parts need to go through a high-temperature steam process during production. In particular, ferrous metal parts are heated in superheated steam for a predetermined time to form a dense oxide film on the surface of the metal parts, which increases the hardness and wear resistance of the metal parts, thereby extending their service life.

[0003] When metal parts are subjected to high-temperature steam treatment, the bottom of the metal parts is pressed against the end face of the high-temperature steam device due to their own weight, which prevents the bottom of the metal parts from directly contacting the high-temperature steam. This affects the formation of the oxide film on the bottom of the metal parts, thereby reducing the production quality of the metal parts. Summary of the Invention

[0004] To improve the quality of metal parts production, this application provides a steam treatment apparatus for metal parts.

[0005] This application provides a steam treatment device for metal parts, which adopts the following technical solution:

[0006] A steam treatment device for metal parts includes a housing and a stirring assembly. The housing has a steam chamber for containing high-temperature steam. The stirring assembly includes a stirring rod and multiple limiting balls. The multiple limiting balls are spaced apart and connected to the outer wall of the stirring rod. The arrangement direction of the limiting balls is parallel to the axis of the stirring rod. Each limiting ball includes a hemisphere 1 and a hemisphere 2. Hemisphere 1 is connected to the stirring rod. A locking assembly connects hemisphere 1 and hemisphere 2 to form a limiting ball. A limiting cavity for containing metal parts is left between hemisphere 1 and hemisphere 2. When the stirring rod rotates, it drives the metal parts to rotate within the limiting cavity. Multiple filter holes are spaced apart on both hemisphere 1 and hemisphere 2. The filter holes connect the limiting cavity and the steam chamber. High-temperature steam in the steam chamber enters the limiting cavity through the filter holes.

[0007] By adopting the above technical solution, the metal parts are placed between hemisphere one and hemisphere two. The locking assembly splices hemisphere one and hemisphere two to form a limiting sphere, which confines the metal parts within the limiting cavity. High-temperature steam in the steam chamber enters the limiting cavity through the filter holes and fully contacts the metal parts. At the same time, the stirring rod rotates, causing the metal parts to rotate within the limiting cavity, thus achieving full contact between the high-temperature steam and the metal parts, ensuring the formation of an oxide film on the metal parts, and thereby improving the production quality of the metal parts.

[0008] Optionally, both hemisphere one and hemisphere two are connected to an elastic pad on the side facing the limiting cavity, and the elastic pad can abut against the metal parts.

[0009] By adopting the above technical solution, when the metal parts rotate in the limiting cavity, the metal parts impact the elastic pad. The elastic pad deforms under the force of the metal parts, which reduces the reaction force of the elastic pad on the metal parts, reduces damage to the metal parts, ensures the structural strength of the metal parts, and improves the production quality of the metal parts.

[0010] Optionally, the locking component includes multiple locking blocks and multiple elastic hooks. The multiple locking blocks are connected at intervals on the side of hemisphere one facing hemisphere two, and the multiple elastic hooks are connected at intervals on the side of hemisphere two facing hemisphere one. The elastic hooks and locking blocks correspond one-to-one. When hemisphere one and hemisphere two are spliced ​​together to form a limiting sphere, the locking blocks are embedded in the elastic hooks to form a fixed shape.

[0011] By adopting the above technical solution, the metal parts are placed between hemisphere one and hemisphere two. Hemisphere two abuts against hemisphere one to form a limiting ball. At the same time, locking block one is embedded in the elastic hook to form a fixation, so that hemisphere two is not easy to shift on hemisphere one, thereby improving the stability of the metal parts in the limiting cavity.

[0012] Optionally, the end face of the elastic hook facing the locking block is provided with a guide surface. The inclination height of the guide surface decreases as the distance to the second hemisphere decreases. The guide surface can abut against the locking block and guide the locking block to be embedded in the elastic hook.

[0013] By adopting the above technical solution, the tilt height of the guide surface decreases as the distance to hemisphere 2 decreases. When hemisphere 1 and hemisphere 2 are spliced ​​together to form a limiting sphere, the guide surface abuts against the limiting block and guides the limiting block to be embedded in the elastic hook, thereby improving the stability of the limiting block embedded in the elastic hook.

[0014] Optionally, a fastening device is connected between the locking block and the elastic hook. The fastening device includes an actuating component, a fastening gear, a first fastening rack, and a second fastening rack. The locking block has a locking cavity that extends through the locking block away from the first hemisphere. The fastening gear is rotatably connected to the inner wall of the locking cavity. The first fastening rack is slidably connected to the inner wall of the locking cavity and engages the fastening gear. The second fastening rack is slidably connected to the inner wall of the locking cavity and engages the fastening gear. The sliding direction of the first fastening rack and the sliding direction of the second fastening rack are perpendicular to each other. The elastic hook has a fastening groove on the side facing the locking block for the end of the first fastening rack to be inserted. The actuating component is connected between the elastic hook and the second fastening rack. When the locking block is inserted into the elastic hook, the locking cavity communicates with the fastening groove. The actuating component drives the second fastening rack to slide towards the elastic hook. The fastening gear rotates, driving the first fastening rack to slide towards the fastening groove. The end of the first fastening rack is inserted into the fastening groove to form a limit.

[0015] By adopting the above technical solution, when hemisphere one and hemisphere two are spliced ​​together to form a limiting ball, the locking block is embedded in the elastic hook, the locking cavity is connected to the fastening groove, and at the same time the activation component drives the fastening rack two to slide towards the elastic hook. The fastening gear rotates, driving the fastening rack one to slide towards the fastening groove. The end of the fastening rack one is embedded in the fastening groove, and the outer wall of the fastening rack one abuts against the inner wall of the fastening groove to form a fixation, making it difficult for the locking block to detach from the elastic hook, thereby improving the clamping force between the locking block and the elastic hook.

[0016] Optionally, the starting component includes a magnetic block one and a magnetic block two. The magnetic block one is connected to the side of the fastening rack two facing the elastic hook, and the magnetic block two is connected to the side of the elastic hook facing the magnetic block one. The magnetic blocks one and two attract each other and drive the fastening rack two to slide closer to the elastic hook.

[0017] By adopting the above technical solution, when the locking block is embedded in the elastic hook, magnetic block one and magnetic block two correspond one to one and face each other. Magnetic block one and magnetic block two are attracted by each other and drive fastening rack two to slide towards the elastic hook. The fastening gear rotates, which drives fastening rack one to slide towards the fastening groove. The end of fastening rack one is embedded in the fastening groove to form a fixation, thereby ensuring the stability of the fastening device operation.

[0018] Optionally, the fastening device further includes a fastening elastic element, one end of which is connected to the inner wall of the locking cavity in the direction of elastic force, and the other end of which is connected to the fastening rack. The fastening elastic element has the elastic force to drive the fastening rack to slide towards the hemisphere, and the end of the fastening rack tends to be flush with the end face of the locking block.

[0019] By adopting the above technical solution, when the metal parts in the limiting cavity are processed, the worker drives the elastic hook to deform away from the locking block, the magnetic block two moves away from the magnetic block one, the attraction between the magnetic block one and the magnetic block two is reduced, the elastic force of the fastening elastic element drives the fastening rack one to slide away from the fastening groove, the end of the fastening rack one is disengaged from the fastening groove, the limiting effect of the pair of elastic hooks of the fastening rack disappears, and the locking block stably disengages from the elastic hook.

[0020] Optionally, the housing is connected to a connecting assembly, which includes a connecting plate, multiple magnetic blocks three and multiple magnetic blocks four. The connecting plate is slidably connected to the inner wall of the steam chamber. The sliding direction of the connecting plate is perpendicular to the rotation axis of the stirring rod. Each magnetic block three corresponds to one hemisphere two. The magnetic block three is connected to the side of hemisphere two away from hemisphere one. Multiple magnetic blocks four are spaced apart and connected to the side of the connecting plate facing hemisphere one. Each magnetic block four corresponds to one hemisphere one. When hemisphere two and magnetic blocks four are placed in a one-to-one correspondence, the magnetic blocks three and four attract each other and confine hemisphere two to magnetic blocks four. The connecting plate slides towards hemisphere one. Hemisphere two and hemisphere one are joined together to form a limiting sphere.

[0021] By adopting the above technical solution, when the metal part is placed in the inner cavity of hemisphere one, hemisphere two is placed on magnetic block four. Magnetic block four and magnetic block three attract each other and limit hemisphere two to magnetic block four. The connecting plate slides towards hemisphere one. Hemisphere two and hemisphere one are spliced ​​together to form a limiting sphere and limit the metal part to the limiting cavity. There is no need for workers to splice and fix hemisphere two to hemisphere one in sequence, which improves the stability of the connection between hemisphere one and hemisphere two.

[0022] Optionally, the connecting assembly further includes a connecting screw, which is rotatably connected to the inner wall of the steam chamber. The rotation axis of the connecting screw and the sliding direction of the connecting plate are parallel to each other. The connecting plate is threadedly connected to the connecting screw, and the rotation of the connecting screw drives the connecting plate to approach the hemisphere.

[0023] By adopting the above technical solution, when the connecting screw rotates, it drives the connecting plate to approach the hemisphere along the axis of the connecting screw, making it less likely for the connecting plate to deviate when sliding on the inner wall of the steam chamber, thereby improving the stability of the sliding of the connecting plate.

[0024] Optionally, a drive assembly is connected to the connecting lead screw, which can drive the connecting lead screw to rotate.

[0025] By adopting the above technical solution, the drive component drives the connecting screw to rotate, eliminating the need for manual control of the connecting screw rotation by the operator, reducing the workload of the operator, and improving the ease of use of the steam treatment device for metal parts.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] The stirring rod and the limiting ball are designed so that the stirring rod rotates and drives the metal parts to rotate in the limiting cavity, so as to achieve full contact between high temperature steam and metal parts, ensure the formation of oxide film on metal parts, and thus improve the production quality of metal parts.

[0028] The installation of elastic pads reduces the reaction force exerted by the elastic pads on metal parts, thereby reducing damage to the metal parts, ensuring the structural strength of the metal parts, and improving the production quality of the metal parts.

[0029] The locking blocks and elastic hooks are designed so that the locking blocks are embedded in the elastic hooks one by one to form a fixed position, making it difficult for the second hemisphere to shift on the first hemisphere, thereby improving the stability of the metal parts in the limiting cavity.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a steam treatment apparatus for metal parts. (Refer to...) Figure 1 and Figure 2 A steam treatment device for metal parts includes a housing 1 and a stirring assembly 2. In this embodiment, the housing 1 is cylindrical and has a steam chamber 11 for containing high-temperature steam. A cover 3 is rotatably connected to the housing 1. The rotation axis of the cover 3 is parallel to the axis of the housing 1. The cover 3 covers the housing 1 and seals the steam chamber 11. The stirring assembly 2 is connected to the housing 1 and is used to drive the metal parts to rotate in the steam chamber 11, so that the metal parts are in full contact with the high-temperature steam, and an oxide film is stably formed on the surface of the metal parts, thereby improving the production quality of the metal parts.

[0036] Reference Figure 1 and Figure 2 The stirring assembly 2 includes a stirring rod 21, a stirring motor 22, and multiple limiting balls 23. The stirring motor 22 is fixed to the outer wall of the housing 1 by bolts. The axis of the stirring motor 22 coincides with the axis of the housing 1, and the end of the stirring motor 22 protrudes from the inner wall of the steam chamber 11. The stirring rod 21 includes a stirring part 211 and multiple connecting parts 212. In this embodiment, both the connecting parts 212 and the stirring part 211 are cylindrical. The stirring part 211 is coaxially fixed on the motor shaft of the stirring motor 22. The multiple connecting parts 212 are divided into two groups. The multiple connecting parts 212 in the same group are welded and fixed to the outer wall of the stirring part 211 at even intervals. The axis of the connecting part 212 and the axis of the stirring part 211 are perpendicular to each other. The arrangement direction of the multiple connecting parts 212 in the same group is parallel to the axis of the stirring part 211, and the two groups of connecting parts 212 are evenly distributed around the axis of the stirring part 211.

[0037] Reference Figure 2 and Figure 3 The limiting ball 23 and the connecting part 212 correspond one-to-one. The limiting ball 23 includes a first hemisphere 231 and a second hemisphere 232, which are spliced ​​together to form the limiting ball 23. A limiting cavity 2321 for accommodating metal parts is left between the first hemisphere 231 and the second hemisphere 232. Multiple filter holes 2322 are evenly spaced on the outer rings of the first hemisphere 231 and the second hemisphere 232, and the filter holes 2322 are connected to the limiting cavity 2321. The outer ring of the first hemisphere 231 away from the second hemisphere 232 is coaxially fixed to the end of the connecting part 212 away from the stirring part 211. An elastic pad 4 is fixed to the inner rings of the first hemisphere 231 and the second hemisphere 232 facing each other. The material of the elastic pad 4 can be rubber or silicone. In this embodiment, the material of the elastic pad 4 is rubber, which has a certain deformation ability and can abut against the metal parts.

[0038] Reference Figure 1 and Figure 3When the stirring motor 22 is running, it drives the stirring part 211 to rotate, causing the metal parts to rotate within the limiting cavity 2321. The force exerted by the metal parts on the elastic pad 4 causes the elastic pad 4 to deform, reducing the reaction force of the elastic pad 4 on the metal parts, reducing wear on the metal parts, and improving the production quality of the metal parts. At the same time, the high-temperature steam in the steam chamber 11 enters the limiting cavity 2321 through the filter hole 2322. The high-temperature steam fully contacts the metal parts in the limiting cavity 2321, ensuring the formation of oxide film on the metal parts, thereby improving the production quality of the metal parts.

[0039] Reference Figure 3 A locking component 5 connects hemisphere 1 231 and hemisphere 2 232, which can coaxially limit hemisphere 2 232 to be positioned on hemisphere 1 231. The locking component 5 includes multiple locking blocks 51 and multiple elastic hooks 52. The multiple locking blocks 51 are evenly welded and fixed to the outer ring of hemisphere 1 231 facing hemisphere 2 232, and are evenly distributed around the axis of hemisphere 1 231. The elastic hooks 52 can be made of rubber or silicone; in this embodiment, the elastic hooks 52 are made of rubber, which has a certain deformation capability. The multiple elastic hooks 52 are evenly fixed to the outer ring of hemisphere 2 232 facing hemisphere 1 231, and are evenly distributed around the axis of hemisphere 2 232, with each elastic hook 52 corresponding to a locking block 51.

[0040] Reference Figure 3 The elastic hook 52 includes a first deformation part 521, a second deformation part 522, and a third deformation part 523. In the embodiments of this application, the first deformation part 521, the second deformation part 522, and the third deformation part 523 are all strip plates. The ends of the first deformation part 521, the second deformation part 522, and the third deformation part 523 are fixed in sequence. The end of the first deformation part 521 away from the second deformation part 522 is fixed on the second hemisphere 232. A locking space 5231 is provided between the first deformation part 521, the second deformation part 522 and the third deformation part 523 for the locking block 51 to be inserted. The end of the third deformation part 523 away from the second deformation part 522 faces the second hemisphere 232. A guide surface 5232 is provided on the side of the third deformation part 523 facing the second hemisphere 232. The inclination height of the guide surface 5232 increases as the distance to the second deformation part 522 decreases. The guide surface 5232 can abut against the locking block 51 and guide the locking block 51 to be inserted into the locking space 5231.

[0041] Reference Figure 3When hemisphere 1 231 and hemisphere 2 232 are joined together to form the limiting ball 23, the locking block 51 and the elastic hook 52 correspond one-to-one. The guide surface 5232 abuts against the locking block 51 and guides the locking block 51 to be embedded in the locking space 5231. The outer wall of the locking block 51 abuts against the inner wall of the locking space 5231 to form a limit, making it difficult for hemisphere 2 232 and hemisphere 1 231 to shift, thereby improving the connection stability between hemisphere 1 231 and hemisphere 2 232.

[0042] Reference Figure 2 and Figure 3 A fastening device 6 is connected between the locking block 51 and the elastic hook 52. The fastening device 6 can confine the locking block 51 within the locking space 5231. The fastening device 6 includes an actuating component 61, a fastening gear 62, a fastening rack 1 63, a fastening rack 2 64, and a fastening elastic element 65. A locking cavity 511 is formed on the side of the locking block 51 away from the hemisphere 1 231. The locking cavity 511 penetrates the locking block 51 in a direction away from the hemisphere 232. The fastening gear 62 is rotatably connected to the inner wall of the locking cavity 511. The rotation axis of the fastening gear 62 is perpendicular to the axis of the connecting part 212. The fastening rack 63 is slidably connected to the inner wall of the locking cavity 511. The sliding direction of the fastening rack 63 is parallel to the axis of the stirring part 211. The fastening rack 63 meshes with the fastening gear 62, and the fastening rack 63 is located on the side of the fastening gear 62 closer to the hemisphere 232. The fastening rack 64 is slidably connected to the inner wall of the locking cavity 511. The sliding direction of the fastening rack 64 is parallel to the axis of the connecting part 212. The fastening rack 64 meshes with the fastening gear 62, and the fastening rack 64 is located on the side of the fastening gear 62 away from the hemisphere 231.

[0043] Reference Figure 3 The fastening elastic element 65 can be a compression spring or a tension spring. In this embodiment, the fastening elastic element 65 is a tension spring, which has a certain deformation capability. One end of the fastening elastic element 65 in the direction of elastic force is fixed to the inner wall of the locking cavity 511, and the other end of the fastening elastic element 65 in the direction of elastic force is fixed to the side of the fastening rack 63 facing the hemisphere 231. The fastening elastic element 65 has the elastic force to drive the fastening rack 63 to slide closer to the locking cavity 511, and the end of the fastening rack 63 tends to be flush with the end face of the locking block 51.

[0044] Reference Figure 3The end of the first fastening rack 63 away from the fastening elastic member 65 faces the second deformation part 522, and the end of the second fastening rack 64 away from the fastening gear 62 faces the third deformation part 523. The second deformation part 522 has a fastening groove 5221 for the end of the first fastening rack 63 to be inserted, and the fastening groove 5221 extends through the second deformation part 522. The actuating component 61 is connected between the third deformation part 523 and the second fastening rack 64. The actuating component 61 can drive the first fastening rack 63 to slide towards the third deformation part 523, causing the end of the first fastening rack 63 to be inserted into the fastening groove 5221 to form a limit. The actuating component 61 includes a magnetic block 611 and a magnetic block 612. The magnetic block 611 is fixed on the side of the second fastening rack 64 facing the third deformation part 523, and the magnetic block 612 is fixed on the side of the third deformation part 523 facing the magnetic block 611.

[0045] Reference Figure 3 When the locking block 51 is embedded in the locking space 5231, the fastening groove 5221 connects to the locking cavity 511. At the same time, the magnetic block 611 and the magnetic block 612 correspond one-to-one. The magnetic block 611 and the magnetic block 612 attract each other and drive the fastening rack 64 to slide towards the deformation part 523. The fastening gear 62 rotates, driving the fastening rack 63 to slide towards the fastening groove 5221. The end of the fastening rack 63 is embedded in the fastening groove 5221. The outer wall of the fastening rack 63 abuts against the inner wall of the fastening groove 5221 to form a fixation, so that the locking block 51 is not easy to shift in the locking space 5231, thereby improving the connection stability between the locking block 51 and the elastic hook 52.

[0046] Reference Figure 1 and Figure 2 A connecting component 7 is connected to the housing 1. The connecting component 7 is used to limit the second hemisphere 232 and drive the second hemisphere 232 to be spliced ​​and fixed on the first hemisphere 231. In this embodiment of the application, there are two connecting components 7, and each connecting component 7 corresponds one-to-one with each set of first hemispheres 231.

[0047] Reference Figure 2 and Figure 3 The connecting component 7 includes a connecting plate 71, a connecting screw 72, multiple magnetic blocks 73 and multiple magnetic blocks 74. The magnetic blocks 73 correspond one-to-one with the hemisphere 232. The magnetic blocks 73 are fixed at the end of the hemisphere 232 away from the hemisphere 231.

[0048] Reference Figure 1 and Figure 2 The connecting plate 71 is slidably connected to the inner wall of the steam chamber 11. The sliding direction of the connecting plate 71 is parallel to the axis of the connecting part 212. Multiple magnetic blocks 74 are evenly fixed at intervals on the side of the connecting plate 71 facing the hemisphere 231, and the magnetic blocks 74 correspond one-to-one with the hemisphere 231.

[0049] Reference Figure 2 and Figure 3 Magnetic block 4 74 can attract magnetic block 3 73 and limit hemisphere 2 232 to the side of magnetic block 4 74 facing hemisphere 1 231, and the clamping force between locking block 51 and elastic hook 52 is greater than the attraction force between magnetic block 4 74 and magnetic block 3 73.

[0050] Reference Figure 1 and Figure 2 The connecting screw 72 is rotatably connected to the inner wall of the steam chamber 11. The rotation axis of the connecting screw 72 and the axis of the connecting part 212 are parallel to each other, and the connecting plate 71 is threadedly connected to the connecting screw 72. When the connecting screw 72 rotates, it drives the connecting plate 71 to slide towards the direction of the first hemisphere 231, causing the second hemisphere 232 to be spliced ​​and fixed on the first hemisphere 231 to form the limiting ball 23.

[0051] Reference Figure 1 and Figure 2 A drive assembly 8 connects the two connecting screws 72, enabling the connecting screws 72 to rotate. The drive assembly 8 includes a drive bevel gear 81, a drive motor 82, and two transmission bevel gears 83. One transmission bevel gear 83 is coaxially fixed to the end of one of the connecting screws 72, and the other transmission bevel gear 83 is coaxially fixed to the end of the other connecting screw 72, with the two transmission bevel gears 83 facing each other. The drive motor 82 is fixed to the housing 1 by screws. The axis of the drive motor 82's motor shaft is parallel to the axis of rotation of the fastening gear 62. The end of the drive motor 82's motor shaft passes through the housing 1 and is located inside the steam chamber 11. The drive bevel gear 81 is coaxially fixed to the drive motor 82's motor shaft, and both transmission bevel gears 83 mesh with the drive bevel gear 81.

[0052] Reference Figure 2 and Figure 3 When the drive motor 82 is running, it drives the two connecting screws 72 to rotate, causing the connecting plate 71 to slide towards the direction of hemisphere 1 231, causing hemisphere 232 to be spliced ​​and fixed on hemisphere 1 231 to form a limiting ball 23, and confining the metal parts within the limiting cavity 2321. This eliminates the need for workers to splice and fix hemisphere 232 onto hemisphere 1 231 in sequence, thereby reducing the workload of workers and improving the processing efficiency of metal parts.

[0053] The implementation principle of the steam treatment device for metal parts in this application embodiment is as follows: The operator places multiple metal parts sequentially into the inner cavity of hemisphere 1 231. The drive motor 82 operates, causing two connecting screws 72 to rotate, driving the connecting plate 71 to slide towards hemisphere 1 231. This causes hemisphere 2 232 to be spliced ​​and fixed onto hemisphere 1 231, forming a limiting ball 23, which confines the metal parts within the limiting cavity 2321. Simultaneously, the stirring motor 22 operates, driving the stirring part 211 to rotate, causing the metal parts to rotate within the limiting cavity 2321. The force exerted by the metal parts on the elastic pad 4 causes the elastic pad 4 to deform, reducing the reaction force of the elastic pad 4 on the metal parts, reducing wear on the metal parts, and improving the production quality of the metal parts. At the same time, high-temperature steam in the steam chamber 11 enters the limiting cavity 2321 through the filter holes 2322. The high-temperature steam fully contacts the metal parts within the limiting cavity 2321, ensuring the formation of an oxide film on the metal parts, thereby improving the production quality of the metal parts.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
