Description

Technical Field

[0001] The utility model relates to the technical field of quenching equipment, and particularly relates to a novel anti-deformation device for a quenching furnace. Background Technique

[0002] Quenching workpieces in a quenching furnace is an important metal heat treatment process. During quenching, first, the workpieces are placed in the quenching furnace and heated to an appropriate temperature above the critical point and held for a period of time to cause changes in the crystal structure inside the workpieces, reaching the preparation state required for quenching. Subsequently, the workpieces are quickly taken out of the quenching furnace and put into the quenching medium to achieve rapid cooling.

[0003] When the existing workpieces are quenched, generally, they are directly hoisted onto a bracket by a hoisting method and placed in the quenching furnace for quenching. In addition, when some workpieces are quenched, they are also placed in the quenching furnace in a stacked manner. However, when the workpieces are quenched by hoisting, it is easy for the workpieces to collide with each other during the transfer process, resulting in defects in the workpieces. In addition, when the workpieces are stacked for quenching, micro-deformation is likely to occur. Therefore, the Chinese utility model patent with the publication number CN215517533U: a device for quenching precision parts that can prevent micro-deformation. In this application, the workpieces are suspended on a workpiece suspension tooling, and then the tooling together with the processed workpieces is placed on a conveyor belt and conveyed by the conveyor belt into a muffle furnace for quenching and cooling processing. Using the workpiece suspension tooling to suspend the workpieces can avoid stacking or extrusion between the workpieces. Although this application can stably place, convey, and quench the workpieces, when quenching larger-sized workpieces, the suspension tooling cannot be adjusted. In addition, after the workpieces are heated, they need to be put into a quenching structure for rapid cooling to complete the quenching process of the workpieces. Therefore, this application can only achieve one heating process of the workpieces and is not convenient for the subsequent rapid cooling and quenching of the workpieces. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel anti-deformation device for a quenching furnace, which can effectively solve the problems in the background technique.

[0011] Preferably, the limit pin is in a C-shaped structure, both ends of the limit pin penetrate through the corresponding first jack and the second jack, and nuts are threadedly connected to both ends of the limit pin located outside the first hanging rod. Through the setting of the suspension mechanism and the first hanging rod, the second bearing tray can be hoisted in the combination of the fixing ring and the connecting plate, which is convenient for storing workpieces.

Detailed Description of the Preferred Embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 - 5 shown, a novel anti-deformation device for quenching furnace provided by the present utility model includes a plurality of fixed rings 1. A plurality of connecting plates 2 are fixedly connected between the plurality of fixed rings 1. Two lifting lugs 3 are fixedly installed on the outer side of one of the fixed rings 1. A first supporting tray 4 and a second supporting tray 5 are respectively movably installed in the combination of the fixed ring 1 and the connecting plate 2. A plurality of suspension mechanisms 6 are movably connected between the second supporting tray 5 and one of the fixed rings 1. The suspension mechanism 6 includes a first suspension rod 7 and a second suspension rod 8. The first suspension rod 7 and the second suspension rod 8 are movably connected to each other, and a limit pin 9 is movably installed between the first suspension rod 7 and the second suspension rod 8.

[0023] As Figure 2As shown, the first supporting tray 4 is threadedly connected to the lowermost fixing ring 1. A backing plate 10 is inserted and installed at the top of the first supporting tray 4, and a backing plate 10 is also inserted and installed at the top of the second supporting tray 5. By providing the backing plates 10 at the tops of the first supporting tray 4 and the second supporting tray 5 respectively, it can prevent the workpiece from tipping over or falling out of the through slots in the first supporting tray 4 and the second supporting tray 5 when quenching workpieces of smaller sizes.

[0024] As Figures 1 - 5 shown, a first hook 11 is fixedly installed at the bottom of the first suspension rod 7. An adjustment groove 12 is formed in the first suspension rod 7, and a plurality of first jacks 13 are formed inside the adjustment groove 12. A second hook 14 is fixedly installed at the top of the second suspension rod 8. A plurality of second jacks 15 are formed in the second suspension rod 8. The bottom of the second suspension rod 8 is inserted into the adjustment groove 12. The limit pin 9 is in a C-shaped structure. Both ends of the limit pin 9 penetrate through the corresponding first jack 13 and the second jack 15, and nuts 16 are threadedly connected to both ends of the limit pin 9 located outside the first suspension rod 7. Through the setting of the suspension mechanism 6 and the first suspension rod 7, the second supporting tray 5 can be hoisted into the combination of the fixing ring 1 and the connecting plate 2, which is convenient for storing workpieces. At the same time, the overall length of the first suspension rod 7 and the second suspension rod 8 is realized in cooperation with the limit pin 9, so as to facilitate adjustment according to workpieces of different sizes, and thus facilitate increasing or decreasing the number of second supporting trays 5 in the combination of the fixing ring 1 and the connecting plate 2.

[0025] It should be noted that the present utility model is a new type of anti-deformation device for a quenching furnace. When quenching a workpiece, the workpiece can be first placed on the first supporting tray 4, and the backing plate 10 can be increased or decreased on the first supporting tray 4 and the second supporting tray 5 according to the size of the workpiece.

Then, the first hook 11 at the bottom of the first suspension rod 7 is hooked inside the second supporting tray 5, and the remaining three suspension mechanisms 6 are operated in the same way as above. Subsequently, the second hook 14 at the top of the second suspension rod 8 is hooked on the corresponding fixing ring 1, thus completing the hoisting of the second supporting tray 5. Then, a plurality of workpieces are placed flat on the second supporting tray 5. When the size of the workpiece is small, the limit pin 9 can be removed from the first jack 13 and the second jack 15 of the first suspension rod 7 and the second suspension rod 8 in advance, so that the first suspension rod 7 can be pushed and pulled and adjusted at the bottom of the second suspension rod 8 through the adjustment groove 12. Then, both ends of the limit pin 9 are inserted into the corresponding first jack 13 and the second jack 15 again and the nuts 16 are screwed on, thereby shortening the overall length of the first suspension rod 7 and the second suspension rod 8, and increasing the number of second supporting trays 5 in the combination of the fixing ring 1 and the connecting plate 2.
