Description

Technical Field

[0001] This utility model relates to the field of engine cylinder block manufacturing technology, and in particular to a spare heat treatment device for magnesium alloy engine cylinder blocks. Background Technology

[0002] A magnesium alloy engine block is a core engine component made of magnesium alloy. Through die casting, a lightweight design is achieved, supporting the crankshaft and cylinders. This material has only 66% the density of aluminum alloy, significantly reducing engine weight, indirectly lowering fuel consumption, and improving vehicle power and handling agility. Heat treatment is required during the manufacturing process of magnesium alloy engine blocks. After heat treatment, stress is effectively released, and subsequent polishing is easier.

[0003] The existing spare heat treatment device for magnesium alloy engine cylinder blocks does not have an effective cleaning device during use, and cannot effectively clean the oil and impurities attached to the cylinder block. When cleaning is not performed, the oil and impurities will carbonize at high temperature to form hard particles that embed into the metal matrix, causing stress concentration and reducing the fatigue strength of the material. At the same time, some oil will vaporize at high temperature, producing bubbles that remain inside the cylinder block, weakening the structural density and seriously affecting the quality of the cylinder block. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a backup heat treatment device for magnesium alloy engine cylinder bodies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat treatment device for spare magnesium alloy engine cylinder blocks includes a cleaning assembly. The cleaning assembly includes a base, a cleaning tank mounted on top of the base, a support frame mounted on top of the cleaning tank, an adjustment assembly for adjusting the position of the cylinder block mounted on one side of the support frame, several sets of heating tubes arranged sequentially on the inner wall of one side of the cleaning tank, a protective cover mounted on the inner wall of one side of the cleaning tank, the size and position of the protective cover being adapted to the heating tubes, several sets of water permeable holes arranged sequentially on the protective cover, several sets of ultrasonic vibration heads arranged sequentially on the inner wall of the bottom of the cleaning tank, a speed-regulating motor mounted on one side of the cleaning tank, a drive shaft connected to the output end of the speed-regulating motor, one end of the drive shaft being rotatably connected to the inside of the cleaning tank, a stirring blade mounted on the drive shaft, a drain pipe connected to one side of the cleaning tank, a sealing plug mounted at the end of the drain pipe, and a heat treatment assembly for preparing the cylinder block mounted on one side of the base.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] A spare heat treatment device for magnesium alloy engine cylinder bodies, such as Figure 1-4As shown, the system includes a cleaning assembly, which includes a base 1.

An adjustment component for adjusting the position of the tank is mounted on one side of the support frame 12. Several sets of heating tubes 21 are arranged sequentially on the inner wall of one side of the cleaning tank 16. A protective cover 20 is mounted on the inner wall of one side of the cleaning tank 16. The size and position of the protective cover 20 are adapted to the heating tubes 21. Several sets of water-permeable holes are arranged sequentially on the protective cover 20. Several sets of ultrasonic vibration heads 19 are arranged sequentially on the inner wall of the bottom of the cleaning tank 16. A speed-regulating motor 18 is mounted on one side of the cleaning tank 16. A drive shaft 23 is connected to the output end of one side of the speed-regulating motor 18. One end of the drive shaft 23 is rotatably connected to the inside of the cleaning tank 16. A stirring blade 24 is mounted on the drive shaft 23. A drain pipe 17 is connected to one side of the cleaning tank 16. A sealing plug is provided at the end of the drain pipe 17. A heat treatment assembly for preparing the tank is mounted on one side of the base 1.

[0026] During use, water can be added to the cleaning tank 16. After adding water, the heating element 21 can be activated. The heating element 21 generates heat to heat the water in the cleaning tank 16. The heated water facilitates the dissolution of oil stains. The protective cover 20 provides protection, enclosing the heating element 21 to prevent accidental contact and injury. During heating, the speed-regulating motor 18 activates the drive shaft 23 and the stirring blade 24. The stirring blade 24 agitates the water flow, allowing for more even heat distribution and preventing spillage. In the case of uneven heating, after the water flow is heated, the stirring blade 24 stops rotating. By adjusting the component, the end of the magnesium alloy engine block with stains can be submerged into the water flow in the cleaning tank 16. After submersion, the ultrasonic oscillator 19 can be activated to drive the water flow to vibrate. The heated water flow can dissolve the oil stains on the magnesium alloy engine block. At the same time, the vibration of the water flow can clean the stubborn stains attached to the crevices and the surface. It can clean and remove oil stains and impurities, and avoid the oil stains and impurities remaining to affect subsequent processing. After cleaning, the sealing plug can be removed, and the wastewater can be discharged through the drain pipe 17 for water replacement.

[0027] The adjustment assembly includes a hydraulic cylinder 11, which is mounted on the top of the support frame 12. The telescopic end of the bottom of the hydraulic cylinder 11 can slide through the support frame 12. An adjustment frame 10 is mounted on the bottom of the hydraulic cylinder 11. Clamping cylinders 13 are symmetrically mounted on both sides of the adjustment frame 10. A clamping frame 14 is mounted on the output end of one side of the clamping cylinder 13.

[0028] When in use, the magnesium alloy engine block that needs to be cleaned can be moved to the adjustment frame 10. By starting the two sets of clamping cylinders 13, the two sets of clamping frames 14 can be moved closer to each other to clamp and fix the magnesium alloy engine block. After fixing, the hydraulic cylinder 11 can be started to sink the part of the magnesium alloy engine block that needs to be cleaned into the water of the cleaning pool 16 for cleaning. When other parts need to be cleaned, the clamping frame 14 can be moved to release the clamp and adjust.

Heating can be carried out by energizing the silicon carbide rod 22. Heating by energizing the silicon carbide rod 22 can create a high-temperature environment to complete the heat treatment of the magnesium alloy engine block.

[0031] To prevent damage to the cylinder body during clamping, such as Figure 1 , 3 As shown, a number of buffer pads 15 are provided on one side of the clamping frame 14. The buffer pads 15 are made of rubber and have cavities.

[0032] When in use, the rubber buffer pad 15 can buffer the magnesium alloy engine block when clamping it. The cavity of the buffer pad 15 can further increase the buffering effect and prevent damage to the cylinder block during clamping.

[0034] During use, water can be added to the water tank 9 through the water inlet. After the water is added, the water in the water tank 9 can be transported by the delivery pump 8. After the heat treatment is completed, the water can be transported to the spray frame 25. Water can be sprayed through the nozzles of the spray frame 25 to cool down the magnesium alloy engine block, thereby accelerating the cooling efficiency. The spray frame 25 is made of high temperature resistant material to avoid damage to the spray frame 25 during heat treatment.

[0035] In order to collect wastewater, such as Figure 1 , 3As shown in Figure 4, the heating furnace 6 has several sets of drainage holes arranged in sequence.
