Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and in particular to a tooling for reducing quenching deformation in multi-purpose furnace heat treatment. Background Technology

[0002] When metal workpieces are quenched, the material expands or contracts. Due to the difference in cooling rate between the outer edge and the inside of the workpiece, thermal stress is generated. This thermal stress is superimposed on the structural stress during the quenching process, which causes the metal workpiece to deform. Therefore, it is necessary to use tooling to prevent the bending deformation of metal workpieces. However, existing anti-bending tooling for quenching is difficult to adapt to workpieces of different sizes.

[0003] To address the aforementioned technical issues, a patent document with publication number (CN222455100U) discloses an anti-bending fixture for heat treatment and quenching of metal workpieces. This fixture includes components such as a base plate, an outer frame, crossbars, and movable blocks. The outer frame is fixedly mounted on the base plate, and the crossbars are slidably connected to the inner wall of the outer frame. Movable blocks are fixedly connected to both ends of the crossbars. This invention uses threaded pins to fix the clamping plate, thereby clamping and fixing the workpiece between the clamping plate and the outer frame. The triangular blocks and spherical blocks contact the surface of the metal workpiece, reducing the contact area and minimizing bending deformation. Furthermore, the spacing between the crossbars is adjustable, allowing it to accommodate metal workpieces of different sizes.

[0004] However, the aforementioned existing technology requires adjusting multiple clamping plates and multiple crossbars according to the size of the workpiece, which is cumbersome and results in low quenching efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for reducing quenching deformation in multi-purpose furnace heat treatment, aiming to solve the technical problem in the prior art that requires adjusting multiple clamping plates and multiple crossbars according to the size of the workpiece, which is cumbersome and results in low quenching efficiency.

[0006] To achieve the above objectives, this utility model employs a tooling for reducing quenching deformation in a multi-purpose furnace heat treatment, comprising a frame and a fixing mechanism. The fixing mechanism includes a fixing frame, two mounting plates, a bidirectional threaded rod, a disc, a handle, two sets of clamping assemblies, two sets of abutment assemblies, and multiple sets of support assemblies.

The fixing frame is fixedly connected to the frame and located on the bottom surface of the frame. The two mounting plates are symmetrically arranged on the bottom surface of the frame.

[0007] Each set of the supporting components includes a horizontal plate, a lead screw, a knob, two sets of fixing parts, and two sets of guide parts. The lead screw passes through the frame and is threaded into the frame. One end of the lead screw is fixedly connected to the knob, and the other end of the lead screw is rotatably connected to the horizontal plate. The two sets of fixing parts are symmetrically arranged on one side of the horizontal plate, and the two sets of guide parts are fixedly connected to the horizontal plate.

[0008] Each set of fixing components includes a round rod and a second clamping plate. One end of the round rod is fixedly connected to the horizontal plate, and the other end of the round rod is fixedly connected to the second clamping plate.

[0009] Each set of guide components includes a guide rod and a limiting block. The guide rod passes through the frame and is slidably connected to the frame. One end of the guide rod is fixedly connected to the horizontal plate, and the other end of the guide rod is fixedly connected to the limiting block.

[0010] Each set of support components includes a support rod and a pad. One end of the support rod is fixedly connected to the frame, and the other end of the support rod is fixedly connected to the pad.

This method can effectively solve the problem in the prior art that multiple clamping plates and multiple crossbars need to be adjusted according to the size of the workpiece, which is cumbersome and leads to low quenching efficiency.

The fixing mechanism includes a fixing frame 102, two mounting plates 103, a bidirectional threaded rod 104, a disc 105, a gripping rod 106, two sets of clamping assemblies, two sets of abutting assemblies, and multiple sets of supporting assemblies. Each set of clamping assemblies includes a moving plate 107, a vertical plate 108, a connecting frame 109, and two first clamping plates 110. Each set of abutting assemblies includes a horizontal plate 111, a lead screw 112, a knob 113, two sets of fixing parts, and two sets of guiding parts. Each set of fixing parts includes a round rod 114 and a second clamping plate 115. Each set of guiding parts includes a guide rod 116 and a limiting block 117. Each set of supporting assemblies includes a support rod 118 and a pad block 119. The aforementioned solution solves the problem in the prior art that multiple clamping plates and multiple horizontal rods need to be adjusted according to the size of the workpiece, which is cumbersome and leads to low quenching efficiency.

[0021] In this specific embodiment, the fixing frame 102 is fixedly connected to the frame 101 and located on the bottom surface of the frame 101. Two mounting plates 103 are symmetrically arranged on the bottom surface of the frame 101. The two ends of the bidirectional threaded rod 104 are rotatably connected to the two mounting plates 103 respectively. The disc 105 is fixedly connected to one end of the bidirectional threaded rod 104. The gripping rod 106 is disposed on one side of the disc 105. Two sets of clamping assemblies are symmetrically arranged inside the frame 101. The moving plate 107 is threadedly engaged with the bidirectional threaded rod 104. One end of the upright plate 108 is fixedly connected to the moving plate 107. The other end of the upright plate 108 penetrates the frame 101 and is fixedly connected to the connecting frame 109. Two first clamping plates 110 are fixedly connected to the connecting frame 109 respectively. The abutment components are symmetrically arranged on both sides of the frame 101, and multiple sets of the support components are arranged on the bottom surface of the frame 101. In actual use, the workpieces are placed in the frame 101, and then the gripping rod 106 is rotated. The gripping rod 106 drives the disc 105 to rotate, and the disc 105 drives the lead screw 112 to rotate, so that the two moving plates 107 move relative to each other. The moving plates 107 drive the upright plate 108 to move, and the upright plate 108 drives the fixed connecting frame 109 to move. The connecting frame 109 drives the two first clamping plates 110 to move, thereby abutting one side of multiple workpieces against the fixed frame 102. Then, the other side of multiple workpieces is abutted against the fixed frame 102 by the two sets of clamping components, thereby fixing multiple workpieces and reducing the degree of deformation of workpieces during quenching.

[0022] The lead screw 112 passes through the frame 101 and is threadedly engaged with the frame 101. One end of the lead screw 112 is fixedly connected to the knob 113, and the other end of the lead screw 112 is rotatably connected to the horizontal plate 111. Two sets of fixing members are symmetrically arranged on one side of the horizontal plate 111, and two sets of guide members are fixedly connected to the horizontal plate 111. In actual use, rotating the knob 113 causes the lead screw 112 to rotate, which in turn moves the horizontal plate 111, and the horizontal plate 111 moves the two sets of fixing members.

[0023] Secondly, one end of the round rod 114 is fixedly connected to the horizontal plate 111, and the other end of the round rod 114 is fixedly connected to the second clamping plate 115. In actual use, the horizontal plate 111 drives the round rod 114 to move, and the round rod 114 drives the second clamping plate 115 to move, thereby holding the workpiece against the fixed frame 102.

[0024] Meanwhile, the guide rod 116 passes through the frame 101 and is slidably connected to the frame 101. One end of the guide rod 116 is fixedly connected to the horizontal plate 111, and the other end of the guide rod 116 is fixedly connected to the limiting block 117. In actual use, the horizontal plate 111 moves, causing the guide rod 116 to slide on the frame 101, thereby guiding the horizontal plate 111.

[0025] In addition, one end of the support rod 118 is fixedly connected to the frame 101, and the other end of the support rod 118 is fixedly connected to the pad 119. In actual use, the support rod 118 is used to support the frame 101, and the pad 119 can enhance the stability of the support rod 118.

[0026] Using a multi-purpose furnace heat treatment fixture to reduce quenching deformation according to this embodiment, in specific use, workpieces are placed in the frame 101, and then the gripping rod 106 is rotated. The gripping rod 106 drives the disc 105 to rotate, and the disc 105 drives the lead screw 112 to rotate, causing the two moving plates 107 to move relative to each other. The moving plates 107 drive the upright plate 108 to move, and the upright plate 108 drives the fixed connecting frame 109 to move. The connecting frame 109 drives the two first clamping plates 110 to move, thereby connecting one side of multiple workpieces to the fixed... The frame 102 is used to hold the workpiece in place. Then, the two knobs 113 are rotated respectively. The knobs 113 drive the lead screw 112 to rotate, causing the horizontal plate 111 to move. The horizontal plate 111 drives the round rod 114 to move, and the round rod 114 drives the second clamping plate 115 to move, thereby holding the other side of the workpiece against the fixed frame 102 and fixing multiple workpieces. This can reduce the degree of deformation of the workpiece during quenching. This method can effectively solve the problem in the prior art that multiple clamping plates and multiple horizontal rods need to be adjusted according to the size of the workpiece, which is cumbersome and leads to low quenching efficiency.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
