Description

Technical Field

[0001] This application relates to the technical field of metal processing, and in particular to an impregnation treatment apparatus for processing metal castings. Background Technology

[0002] During the casting process, molten metal solidifies in the mold, accompanied by phenomena such as gas escape and slag entrapment. This can easily lead to defects such as porosity, looseness, and microcracks inside the casting. These internal defects can seriously affect the mechanical properties, sealing performance, and corrosion resistance of the casting, thus limiting its application in precision machinery, automotive parts, aerospace, and other fields.

[0003] A search revealed that Chinese Patent Publication No. CN221453131U discloses an immersion treatment device for metal casting processing, which includes a tank for storing immersion liquid, a feeding structure for carrying metal castings, and a lifting component for driving the feeding structure to lift and lower to complete the immersion and removal operations of the castings. It basically realizes the basic functions of automation in the immersion treatment of metal castings.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In existing devices, after the feeding structure immerses the casting in the impregnation liquid within the tank, the casting is often in a relatively static state or only moves up and down using simple lifting actions, resulting in poor fluidity of the impregnation liquid on and around the casting surface. For metal castings with complex structures or small pore sizes, the impregnation liquid cannot quickly and evenly reach all internal pore areas, which not only prolongs the impregnation treatment time and reduces production efficiency but also easily leads to some pores not being fully filled, affecting the consistency and reliability of the impregnation treatment. Utility Model Content

[0005] To address the problem of poor fluidity of the impregnation solution on and around the casting surface, this application provides an impregnation treatment apparatus for metal casting processing.

[0006] This application provides an immersion treatment device for metal casting processing, which adopts the following technical solution: it includes a box body, a support frame is installed on the upper end of the box body, a feeding frame is provided between the support frame and the box body, a lifting component is provided between the feeding frame and the support frame, a swing plate is provided below the feeding frame, the two ends of the swing plate are rotatably connected to the box body through fixing parts, a driving component is provided on one side of the swing plate, and a snap-fit ​​component is provided between the bottom of the feeding frame and the swing plate.

[0007] Optionally, the fixing component includes a fixing plate, which is U-shaped and installed on the bottom wall of the box. Both ends of the fixing plate are rotatably mounted with a rotating shaft, and one end of the two rotating shafts is fixedly connected to the swing plate.

[0008] Optionally, the drive assembly includes a drive shaft rotatably mounted on the housing. The axis of the drive shaft intersects and is perpendicular to the axis of the rotating shaft. One end of the drive shaft is provided with a drive source, which is mounted on the housing. The other end of the drive shaft is fixedly mounted with a connecting plate, which is L-shaped. One end of the connecting plate is rotatably mounted with a connecting rod, and one end of the connecting rod is rotatably connected to the swing plate through a sleeve.

[0009] Optionally, the snap-fit ​​component includes a plug, which is fixedly installed at the lower end of the feeding frame. The swing plate is provided with a slot corresponding to the plug, and the plug is inserted into the slot.

[0010] Optionally, the lifting assembly includes two electric telescopic rods, which are symmetrically arranged at both ends of the feeding frame. The electric telescopic rods are fixedly connected to the support frame, and the feeding frame has locking blocks at both ends. The electric telescopic rods are engaged with the lower ends of the locking blocks.

[0011] Optionally, drive rods are symmetrically arranged on both sides of the fixed plate, the drive rods are rotatably mounted on the box body, the drive rods are provided with helical blades, and a heating plate is installed on the inner wall of the box body.

[0012] Optionally, both the drive shaft and the drive rod are equipped with sprockets, and the drive shaft and the sprockets on the drive rod are connected by a chain.

[0013] In summary, this application includes the following beneficial technical effects: 1. This utility model uses a drive assembly to drive a swing plate to swing back and forth. The feeding frame is linked to the swing plate via a snap-fit ​​component, which causes the metal casting to shake regularly in the impregnation liquid. This enhances the fluidity of the impregnation liquid on the surface of the casting and around complex structures and small pores, speeds up the speed at which the impregnation liquid reaches all internal pore areas, reduces the situation where some pores are not fully filled, shortens the impregnation treatment time, improves production efficiency, and improves the consistency and reliability of the impregnation treatment. It solves the problem of insufficient fluidity caused by the casting being stationary or simply moved in the existing device.

[0014] 2. This utility model uses a sprocket and chain to drive the drive rod to rotate, causing the spiral blades to stir the impregnation liquid. Combined with a heating plate to maintain the optimal activity state of the impregnation liquid, it further enhances the overall fluidity and uniformity of the impregnation liquid, ensuring that the impregnation liquid can more fully and evenly contact all areas of the casting. Especially for castings with complex structures or small pores, it ensures that the impregnation liquid deeply fills every defect, avoiding the problem of insufficient local impregnation caused by poor fluidity, and improving the quality and stability of the impregnation treatment.

[0017] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0018] This application discloses an impregnation treatment apparatus for processing metal castings. For example... Figure 1 , Figure 2 As shown, the device includes a housing 1, a support frame 2 mounted on the upper end of the housing 1, a PLC controller mounted on the front side of the housing 1, a material feeding frame 3 between the support frame 2 and the housing 1, the material feeding frame 3 being made of 304 stainless steel with a sandblasted anti-corrosion treatment, and the frame being mesh-like, and a lifting assembly between the material feeding frame 3 and the support frame 2, the lifting assembly including two electric telescopic rods 17.

[0019] See Figure 1 , Figure 2 As shown, two electric telescopic rods 17 are symmetrically arranged at both ends of the feeding frame 3. The electric telescopic rods 17 are fixedly connected to the support frame 2. The feeding frame 3 is provided with locking blocks 18 at both ends. The electric telescopic rods 17 are locked to the lower ends of the locking blocks 18. A swing plate 5 is provided below the feeding frame 3. The two ends of the swing plate 5 are rotatably connected to the box body 1 through fixing parts. The fixing parts include a fixing plate 4. The fixing plate 4 is set in a "U" shape. The fixing plate 4 is installed on the inner bottom wall of the box body 1. Drive rods 14 are symmetrically arranged on both sides of the fixing plate 4.

[0020] See Figure 2 , Figure 3 , Figure 4As shown, the drive rod 14 is rotatably mounted on the housing 1. The drive rod 14 is provided with a spiral blade 15. Both the drive shaft 10 and the drive rod 14 are equipped with sprockets 20. The drive shaft 10 and the sprockets 20 on the drive rod 14 are connected by a chain 19. A heating plate 16 is installed on the inner wall of the housing 1. The heating plate 16 is an armored electric heating plate with a built-in PT100 temperature sensor. Both ends of the fixed plate 4 are rotatably mounted with a rotating shaft 6. The rotating shaft 6 is made of 40Cr alloy steel. The surface of the swing plate 5 is coated with an epoxy resin anti-corrosion layer.

[0021] See Figure 2 , Figure 3 As shown, one end of each of the two rotating shafts 6 is fixedly connected to the swing plate 5. A drive assembly is provided on one side of the swing plate 5. The drive assembly includes a drive shaft 10, which is rotatably mounted on the housing 1. An angle sensor and a sealing ring are provided between the drive shaft 10 and the housing 1. The axis of the drive shaft 10 is perpendicular to the axis of the rotating shaft 6. A drive source 11 is provided at one end of the drive shaft 10. The drive source 11 is mounted on the housing 1. The drive source 11 is a servo motor. The PLC controller is used to control the electric telescopic rod 17, the heating plate 16 and the drive source 11, and to link with the sensor and the angle sensor.

[0022] See Figure 2 , Figure 3 As shown, a connecting plate 9 is fixedly installed at the other end of the drive shaft 10. The connecting plate 9 is set in an "L" shape. A connecting rod 8 is rotatably installed at one end of the connecting plate 9. One end of the connecting rod 8 is rotatably connected to the swing plate 5 through the sleeve 7. A snap-fit ​​component is provided between the bottom of the feeding frame 3 and the swing plate 5. The snap-fit ​​component includes a plug 13. The plug 13 is fixedly installed at the lower end of the feeding frame 3. A slot 12 corresponding to the plug 13 is provided on the swing plate 5. The bottom of the plug 13 is chamfered. The plug 13 is inserted into the slot 12.

[0023] The implementation principle of the immersion treatment device for metal casting processing in this embodiment of the application is as follows: First, a sufficient amount of special immersion liquid for metal casting is injected into the box 1. Then, the heating plate 16 installed on the inner wall of the box 1 is activated to heat the immersion liquid until its temperature is stabilized within a preset range that ensures the optimal activity of the immersion liquid. Then, the operator smoothly places the metal casting to be processed into the feeding frame 3 to complete the casting loading. At this time, the locking blocks 18 at both ends of the feeding frame 3 are stably locked with the lower end of the electric telescopic rod 17. Next, the electric telescopic rod 17 is activated and its synchronous operation is controlled. The electric telescopic rod 17, through the engagement with the locking block 18, drives the feeding frame 3 and the casting inside the frame to slowly descend until the casting is completely immersed in the impregnation liquid in the box 1. During this process, the insert block 13 fixed at the lower end of the feeding frame 3 will be precisely inserted into the corresponding slot 12 on the swing plate 5 to achieve stable linkage between the feeding frame 3 and the swing plate 5. The electric telescopic rod 17 continues to extend and separates from the locking block 18, reaching the middle position between the insert block 13 and the swing plate 5, so as to avoid affecting the subsequent swing of the swing plate 5 and the feeding frame 3. Next, the drive source 11 is started, which drives the drive shaft 10 connected to it to rotate around its own axis. When the drive shaft 10 rotates, it drives the connecting plate 9 to make a circular motion with the drive shaft 10. The end of the connecting plate 9 away from the drive shaft 10 is connected to the connecting rod 8 through rotation, which drives the sleeve 7 to reciprocate to drive the swing plate 5. The swing plate 5 will make a regular reciprocating swing around the rotating shaft 6. At the same time, the feeding frame 3 and the internal casting will swing synchronously with the swing plate 5, so that the casting will make a regular shaking in the immersion liquid. While the drive shaft 10 rotates, the rotation of the drive shaft 10 drives the two drive rods 14 to rotate synchronously via the sprocket 20 and chain 19. When the drive rods 14 rotate, the spiral blades 15 fixed on their surfaces stir the impregnation liquid in the box 1 in all directions, further enhancing the overall fluidity and concentration uniformity of the impregnation liquid. At the same time, the heating plate 16 continues to work to maintain the optimal active temperature of the impregnation liquid, ensuring that the impregnation liquid can fully and evenly contact every surface and internal defect of the casting, avoiding the problem of insufficient pore filling caused by local stagnation of the impregnation liquid.

[0024] After the immersion treatment reaches the preset time, the drive source 11 is turned off, so that the upper surface of the swing plate 5 is horizontal. The drive shaft 10, swing plate 5, drive rod 14 and spiral blade 15 all stop moving, and the immersion liquid returns to a stable state. The heating plate 16 is turned off simultaneously to stop heating the immersion liquid. The electric telescopic rod 17 is started and controlled to retract synchronously. The electric telescopic rod 17 drives the discharge frame 3 and the castings inside that have been immersed to rise slowly through the locking block 18. As the discharge frame 3 rises, the insert block 13 disengages from the slot 12 of the swing plate 5 until the discharge frame 3 rises to the initial high position. Finally, the operator takes out the processed metal castings from the discharge frame 3 to complete a single immersion treatment process.

[0025] 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.
