Description

Technical Field

[0001] This utility model discloses a spring tempering device with high sealing performance, which relates to the field of spring processing technology. Background Technology

[0002] Tempering is a crucial heat treatment process in spring manufacturing. It involves heating the spring to a certain temperature (below the critical point) after quenching, holding it for a period of time, and then cooling it. The purpose of this heat treatment is to improve the mechanical properties of the spring, giving it sufficient elasticity, good toughness, and fatigue life during use.

[0003] Traditional spring tempering devices (such as continuous mesh belt tempering furnaces) have the following problems: hot air or atmosphere is easily leaked in the high-temperature area of ​​the equipment, resulting in energy waste and the risk of heat injury; the furnace body has weak sealing, resulting in large heat loss at the furnace door and interface. Therefore, a spring tempering device with high sealing performance is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a spring tempering device with high sealing performance, which can quickly close the tempering furnace door during processing and achieve a high sealing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spring tempering device with high sealing performance, comprising a tempering furnace, a furnace cover installed on the tempering furnace, a sealing structure installed on the furnace cover, and a clamping device installed on the furnace cover; the sealing structure includes a cover plate, a fixing column provided on the cover plate, four sets of fixing columns evenly distributed at the four corners of the cover plate, a connecting rod hinged to the fixing column, a transmission rod hinged to the other end of the connecting rod, a slide rail structure installed on the transmission rod, a fixing block installed on the other side of the slide rail structure, the fixing block being fixedly connected to the furnace cover, the slide rail structure being able to slide on the fixing block, a transmission groove provided on the fixing block, a transmission wheel provided in the transmission groove, and the transmission wheel being fixedly connected to the cover plate.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples:

[0019] like Figure 1 As shown, a spring tempering device with high sealing performance includes a tempering furnace 1, a furnace cover 2 installed on the tempering furnace 1, a sealing structure 3 installed on the furnace cover 2, and a clamping device 4 installed on the furnace cover 2.

[0020] In this tempering furnace 1, there is a feed port on the furnace cover 2 for placing the springs to be processed into the furnace. The function of the sealing structure 3 is to ensure that the feed port is sealed during operation to prevent heat leakage. The pressure device 4 is used to apply further pressure after the furnace cover 2 is closed to enhance the sealing effect.

[0021] The clamping device 4 is used to quickly clamp and fix the furnace cover 2 to the sealing structure 3, ensuring that the furnace body maintains good sealing performance under high temperature working conditions. The clamping device 4 is a mature existing technology with stable structure and simple operation. It can effectively improve the sealing tightness between the furnace cover 2 and the furnace body. It mainly plays the role of clamping the contact surface between the sealing structure 3 and the furnace cover 2. The specific clamping principle of the device will not be elaborated here.

[0022] Two sets of clamps 4 are provided, located on both sides of the furnace cover 2 respectively, symmetrically distributed to ensure the stable sealing effect of the sealing structure 3 on the furnace cover 2;

[0023] like Figure 2 As shown, the sealing structure 3 includes a cover plate 31, on which a fixing post 32 is provided. The fixing post 32 is provided in four sets evenly distributed at the four corners of the cover plate 31. A connecting rod 33 is hinged to the fixing post 32. A transmission rod 34 is hinged to the other end of the connecting rod 33. A slide rail structure 35 is installed on the transmission rod 34. A fixing block 38 is installed on the other side of the slide rail structure 35. The fixing block 38 is fixedly connected to the furnace cover 2. The slide rail structure 35 can slide on the fixing block 38. A transmission groove 381 is provided on the fixing block 38. A transmission wheel 39 is provided in the transmission groove 381. The transmission wheel 39 is fixedly connected to the cover plate 31.

[0024] The transmission rod 34 is provided in two sets, located on both sides of the cover plate 31, and is symmetrically arranged to ensure balance and stability during the transmission process.

[0025] The transmission groove 381 is a curved combination groove, with one end being a straight groove and the other end being an arc-shaped groove with a certain downward curvature.

[0026] When the hatch is not closed, the drive wheel 39 is located at the top of the straight groove in the drive groove 381. At this time, the connection angle between the connecting rod 33 and the fixed column 32 is inclined. As the hatch gradually closes, the drive wheel 39 slowly slides down the straight groove until it enters the arc groove. The downward arc of the arc groove causes the drive wheel 39 to drive the cover plate 31 to move downward, that is, the cover plate 31 closes the feed inlet, thereby achieving a seal on the feed inlet. When the drive wheel 39 enters the arc groove, because the connecting rod 33 is hinged to the fixed column 32, the connecting rod 33 will change its angle as the drive wheel 39 descends, thereby causing the cover plate 31 to smoothly fit against the edge of the feed inlet. That is, the angle between the connecting rod 33 and the fixed column 32 gradually becomes perpendicular, reducing the straight distance between the cover plate 31 and the furnace cover 2, so that the cover plate 31 can fit more tightly against the edge of the feed inlet, achieving a good sealing effect. Throughout the sealing process, the drive wheel 39 moves along the trajectory of the curved groove to ensure that the descent of the cover plate 31 is smooth and the force is even, avoiding sealing failure due to vibration or uneven pressure. This process requires the operator to close the cover plate 31.

[0027] A fixing rod 36 is provided between two symmetrical sets of transmission rods 34, and a handle 37 is provided on the fixing rod 36;

[0028] The fixed rod 36 is designed to synchronize the connecting movements between the transmission rods 34 and make the structure more stable. The handle 37 is designed to facilitate operation by workers. By manually controlling the movement of the handle 37, the transmission rods 34 are driven to move, thereby realizing the trajectory control of the transmission wheel 39 in the transmission groove 381, further ensuring the accuracy and controllability of the sealing process.

[0029] The rotation of the transmission wheel 39 drives the slide rail structure 35 to slide smoothly in the transmission groove 381, thereby achieving uniform pressing of the cover plate 31 on the furnace cover 2.

[0030] After the cover plate 31 has completed sealing, it is necessary to maintain its movement. Therefore, the function of the clamp 4 is to fix the position of the cover plate 31 to prevent it from shifting or loosening due to external force during use, and at the same time further enhance the density effect.

[0031] The bottom of the cover plate 31 is provided with a sealing gasket layer (not shown in the figure). The sealing gasket layer is made of high temperature resistant elastic material, which can effectively absorb the small gap between the cover plate 31 and the edge of the feed inlet, thereby further improving the sealing performance and ensuring the airtightness and temperature stability inside the furnace.

[0032] A high-efficiency heat insulation layer (not shown in the figure) is provided at the connection between the furnace cover 2 and the cover plate 31. The heat insulation layer adopts a multi-layer composite structure design, which can maintain stable physical properties in high-temperature environments, prevent heat from spreading outward, ensure the safety of operators, and reduce energy loss. At the same time, the synergistic effect of the heat insulation layer and the sealing gasket layer further improves the overall sealing and heat preservation effect, so that the furnace body maintains a constant internal environment during long-term operation, meeting the high requirements of industrial production for temperature control.

[0033] In summary, the coordinated movement of the transmission wheel 39 and the slide rail structure 35 enables the smooth descent and precise positioning of the cover plate 31. Combined with the hinged structure of the connecting rod 33 and the fixed column 32, the cover plate 31 can tightly fit the edge of the feed inlet, forming a good sealing foundation. On this sealing foundation, the fixing effect of the clamping device 4 on the cover plate 31, along with the synergistic protection of the sealing gasket and the heat insulation layer, effectively improves the airtightness and heat preservation performance of the furnace body, ensuring the safe and stable operation of the equipment under high-temperature conditions. The overall structural design is reasonable, the operation is convenient, and the sealing effect is reliable, possessing good practicality and promotional value.

All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
