Description

Technical Field

[0001] This utility model belongs to the field of vacuum welding furnace technology, specifically a vacuum welding furnace temperature control device. Background Technology

[0002] A vacuum reflow oven, also known as a vacuum welding furnace, performs high-quality welding on products in a vacuum environment. During the heating or cooling process, a reducing system (N2, formic acid, N2H2, H2) is introduced to protect the product and solder from oxidation. At the same time, the oxides on the surface of the product and solder react, improving the surface quality of the weld and reducing the void rate.

[0003] In the existing technology, a vacuum furnace temperature and pressure control device with application number 201721898367.5 describes a forward and reverse switch that opens in the forward direction when the temperature inside the heating chamber is too high. At this time, the first electromagnet generates magnetism while the second electromagnet does not. The first electromagnet attracts the moving rod into the left limiting ring, and at the same time, the first fixing rod enters the first fixing groove for fixation. This causes the moving rod to rotate with the rotating rod and, under the action of the steel rope, moves the blocking plate upward to block the heating tube, thereby reducing the temperature inside the heating chamber. When the temperature inside the heating chamber is too low, the forward and reverse switch opens in the reverse direction. However, reducing the temperature inside the heating chamber by blocking the heating tube takes a long time and is not convenient for quickly cooling the welded structure, resulting in low work efficiency.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Specific implementation examples are given below. Example 1:

[0039] Please see Figures 1 to 8 This utility model provides a temperature control device for a vacuum welding furnace, including: a furnace body 1, a temperature control component 4, an auxiliary component 5 and a placement component 6, and a base 2 fixedly installed at the lower end of the furnace body 1. A sealing plate 3 is rotatably connected to the front end of the furnace body 1.

[0040] In this embodiment, the structure to be welded is placed on the placement component 6 and placed inside the furnace body 1. The sealing cover 3 is then tightly fitted to the furnace body 1. Subsequently, the temperature control component 4 is activated to heat the inside of the furnace body 1. After welding is completed, the temperature control component 4 is activated again to cool down the structure. This works in conjunction with the auxiliary component 5 to improve the uniformity of cooling and prevent uneven cooling from causing the welded structure to crack. Example 2:

[0041] Based on Embodiment 1, a temperature control component 4 and an auxiliary component 5 are further disclosed. The temperature control component 4 is installed inside the furnace body 1 to regulate the temperature inside the furnace body 1, and the auxiliary component 5 is installed inside the temperature control component 4 to improve the cooling uniformity.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the temperature control component 4 includes: a welding box 401 fixedly installed inside the furnace body 1; a partition 402 fixedly installed at the rear end of the welding box 401; a fan 403 fixedly installed at the upper end of the partition 402; a heating tube 404 fixedly installed at the upper end of the partition 402 inside the welding box 401; a hydraulic rod 405 fixedly installed at the bottom end of the welding box 401; a heat-conducting plate 406 fixedly installed at the upper end of the hydraulic rod 405; a heat-conducting pipe 407 fixedly installed inside the heat-conducting plate 406; and a cooling pipe 408 connected to the lower end of the heat-conducting pipe 407. The auxiliary component 5 includes: an auxiliary plate 501 slidably connected inside the heat-conducting plate 406; slots 502 are opened at the front and rear ends of the auxiliary plate 501 inside the heat-conducting plate 406; a sliding column 503 is fixedly installed inside the slots 502; a first spring 504 is sleeved on the outside of the sliding column 503; and sliders 505 are fixedly installed at the front and rear ends of the auxiliary plate 501.

[0043] In this embodiment, when heating and welding the structure, the furnace body 1 is evacuated to a vacuum and then inert gas is introduced. The heating tube 404 is then activated, heating the surrounding inert gas. The fan 403 is then activated, blowing the heated gas towards the upper part of the mounting component 6, preheating the parts to be welded on the mounting component 6. Simultaneously, the welding box 401 is divided into upper and lower spaces by the mounting component 6 and the partition 402. Hot gas is delivered to the front end of the welding box 401 and enters the lower half of the welding box 401. It is then drawn out by the fan 403 and re-contacts the heating tube 404 for heating, improving the heat circulation efficiency within the welding box 401 and enhancing the temperature stability around the welded structure. This prevents excessively rapid local heating that could cause deformation of the welded structure. After welding, cooling gas is introduced into the cooling pipe 408. The coolant is introduced into the heat pipe 407 inside the heat-conducting plate 406. Then, the hydraulic rod 405 is activated to lift the heat-conducting plate 406, so that the auxiliary plate 501 inside the heat-conducting plate 406 is in contact with the placement component 6. The auxiliary plate 501 is also made of heat-conducting material. As it is in contact with the placement component 6, the initial cooling of the welded structure is achieved, which avoids the welded structure from cooling down too quickly and causing cracking, and improves the uniformity of cooling. After the initial cooling is completed, the hydraulic rod 405 is activated again to make the heat-conducting plate 406 completely in contact with the placement component 6. At the same time, the auxiliary plate 501 is squeezed and slid into the heat-conducting plate 406. The slider 505 slides in the empty groove 502 and slides on the sliding column 503, and puts pressure on the first spring 504, which facilitates the cooling of the welded structure, improves the uniformity of cooling, and facilitates temperature control inside the vacuum furnace. Example 3:

[0044] Based on Embodiment 1, a placement component 6 is further disclosed, which is installed inside the temperature control component 4.

[0045] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the placement component 6 includes: an overlapping block 601 fixedly installed in the middle of the inside of the welding box 401; a support plate 602 slidably connected to the upper end of the overlapping block 601; a locking block 603 slidably connected to the left and right sides inside the welding box 401; a second spring 604 provided between the locking block 603 and the welding box 401; a locking groove 605 opened on the left and right sides of the support plate 602; and an auxiliary wheel 606 rotatably connected inside the overlapping block 601.

[0046] In this embodiment, after the welding structure is placed on the tray 602, the tray 602 is overlapped on the overlap block 601 and pushed into the welding box 401. After the tray 602 is fully pushed into the welding box 401, the locking block 603 aligns with the locking slot 605. Then, the second spring 604 drives the locking block 603 to pop out from the welding box 401, so that the locking block 603 is locked into the locking slot 605, thereby locking the tray 602, improving the stability of the welding component during placement, and preventing the welding structure from shaking and misaligning due to the wobbling of the tray 602, which would affect the welding effect. At the same time, the overlap block 601 is provided with several auxiliary wheels 606, which facilitates the placement and removal of the tray 602 and improves work efficiency.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
