Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for hydraulic and pneumatic components, and particularly relates to a preheating furnace for heat treatment of hydraulic and pneumatic components. Background Technique

[0002] The heat treatment of hydraulic and pneumatic components is an important technological process. It changes the internal organizational structure and performance of metal or alloy materials through operations such as heating, heat preservation, and cooling, so as to meet the usage requirements of hydraulic and pneumatic components. During the heat treatment process, the preheating furnace is a key device, which is mainly used to preheat the components before the formal heat treatment.

[0003] In the current preheating process, in order to improve the heat treatment efficiency and convenience of the components, a storage frame is generally used as the loading tool for the components. After arranging them neatly, the whole is sent into the preheating furnace for preheating treatment. However, the fixing method between the storage frame and the inside of the preheating furnace mostly relies on bolt connection. Although this connection method is stable, it is particularly cumbersome during the installation and disassembly processes, not only increasing the labor intensity of the operators, but also significantly extending the preheating preparation time and the finishing time after the end, which has an adverse impact on the overall working efficiency. For this reason, we propose a preheating furnace for heat treatment of hydraulic and pneumatic components. Content of the Utility Model

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to the attached Figures 1-7 , a preheating furnace for heat treatment of hydraulic and pneumatic components, includes a furnace body 1 and a furnace cover 2. The furnace cover 2 is covered on the furnace body 1, and the cavity of the furnace cover 2 and the furnace body 1 forms a sealed preheating space. A hanging shaft 3 is provided inside the furnace cover 2. The bottom of the hanging shaft 3 is detachably connected with a storage rack 5 for placing components through a connecting block 4. The storage rack 5 is located in the preheating space. Open the furnace cover 2, place the hydraulic and pneumatic components on the storage rack 5, then make the storage rack 5 return to the sealed preheating space formed by the cavity of the furnace cover 2 and the furnace body 1, and then cover the furnace cover 2. At this time, the hydraulic and pneumatic components can be preheated by the preheating furnace;

[0034] A groove is circumferentially formed on the outer wall of the connecting block 4. A hook 51 is provided at the top of the storage rack 5 and is hooked in the groove. Through the cooperation of the hook 51 and the groove on the connecting block 4, the storage rack 5 can be quickly disassembled and installed, facilitating the quick replacement of the storage rack 5.

[0035] In this embodiment, the groove includes a disassembly groove 41 that breaks through the side wall of the connecting block 4 and a clamping groove 42 that does not break through the side wall of the connecting block 4. A disassembly opening that penetrates the connecting block 4 is provided at the bottom of the disassembly groove 41. The bottom that does not penetrate the connecting block 4 is connected to the clamping groove 42. The cross-section of the clamping groove 42 is the same as the cross-section of the hook part at the top of the hook 51. When installing the storage rack 5, align the hook 51 with the disassembly opening of the disassembly groove 41, then make the hook 51 and the connecting block 4 move towards each other, further making the hook 51 move relatively upward in the disassembly groove 41 and reach the top of the disassembly groove 41. Then make the hook 51 rotate relative to the connecting block 4 and make the hook 51 located above the clamping groove 42. Then make the hook 51 move in the opposite direction relative to the clamping groove 42 and make the hook 51 move into the clamping groove 42, thus completing the installation between the storage rack 5 and the connecting block 4. The disassembly process is the reverse, without using screws for fixation, greatly increasing the replacement efficiency of the storage rack 5.

[0036] In this embodiment, a baffle 43 extending upward is provided in the middle of the disassembly groove 41 to abut against the side wall of the hook 51. The baffle 43 abuts against one side of the hook 51, making the installation between the storage rack 5 and the connecting block 4 more stable and preventing the storage rack 5 from shaking when rotating.

[0037] In this embodiment, a plurality of vertical rods 52 are circumferentially provided inside the storage rack 5. A plurality of support members are provided on the outer wall of the vertical rods 52. A plurality of storage frames 54 for carrying components are provided inside the storage rack 5. The storage frames 54 are installed on the support members. By providing a plurality of support members, a plurality of storage frames 54 can be provided inside the storage rack 5, facilitating the separate placement of components, avoiding the components from contacting each other, and facilitating the overall uniform heating of the components.

[0038] In this embodiment, the support member includes a support block 531 that slides on the outer wall of the vertical rod 52. A bolt 532 is threadedly connected to the support block 531. The support block 531 is fixed to the outer wall of the vertical rod 52 by the frictional force between the bolt 532 and the outer wall of the vertical rod 52. When the bolt 532 is loosened, the support block 531 can slide on the outer wall of the vertical rod 52, further enabling the distance between the storage frames 54 to be adjusted, facilitating the placement of components of different sizes.

[0039] On one side of the support block 531 facing the center of the storage rack 5, a slot 533 is provided. The bottom of the storage frame 54 is circumferentially provided with a plug-in member that cooperates with the slot 533. By the cooperation between the plug-in member and the slot 533, the storage frame 54 can be quickly replaced, facilitating the quick replacement of a suitable storage frame 54 according to components of different shapes, and facilitating the overall uniform heating of the components.

[0040] In this embodiment, the plug-in member includes two plug plates 541. An elastic plate 542 that bends downward is provided between the two plug plates 541. The two plug plates 541 of the plug-in member are inserted into the slot 533 to form an interference fit. The interference fit between the plug-in member and the slot 533 makes the disassembly and installation process simple and fast.

[0041] In this embodiment, a motor base 21 is provided on the furnace lid 2. A driving motor 22 is provided on the motor base 21. The output end of the driving motor 22 is connected to the hanging shaft 3. When the driving motor 22 is started, the hanging shaft 3 drives the storage frame 54 to rotate through the connecting block 4, further enabling the components in the storage frame 54 to be rotationally heated.

[0042] In this embodiment, a first cylinder 11 is provided on one side of the furnace body 1. A support frame 12 is provided at the top of the first cylinder 11. A second cylinder 13 is provided inside the support frame 12. The output end of the second cylinder 13 is connected to the motor base 21. Sliding blocks 23 are provided on both sides of the motor base 21. Sliding grooves 14 for the sliding blocks 23 to slide are provided on both sides of the support frame 12. The direction of the sliding grooves 14 is the same as the movement direction of the output end of the second cylinder 13. After preheating is completed, the first cylinder 11 is started. At this time, the support frame 12 drives the motor base 21 and the furnace lid 2 to move upward, and transports the storage rack 5 out of the furnace body 1. Then the second cylinder 13 is started. At this time, the second cylinder 13 pushes the motor base 21 and the furnace lid 2 to move horizontally, further moving the storage rack 5 away from the furnace opening of the furnace body 1, avoiding scalding the staff due to operating the storage rack 5 at the furnace opening.

[0043] In this embodiment, blades 31 are circumferentially provided on the outer wall of the bottom of the hanging shaft 3. The blades 31 are all located in the preheating space. The hanging shaft 3 drives the blades 31 to rotate in the preheating space, enabling the air in the preheating space to flow, and avoiding the difference in temperature inside and outside the preheating space, which affects the preheating effect of the components.
