Description

Technical Field

[0001] This utility model relates to the field of quenching technology, and in particular to a quenching device for ring forgings. Background Technology

[0002] Ring forgings are a product of the forging industry, a type of forging where a metal billet is shaped into a ring-shaped object with suitable compressive force through plastic deformation under external force. This force is typically achieved using a hammer or pressure. The forging process creates a fine granular structure and improves the physical properties of the metal. During the forging process, ring forgings often require heat treatment to improve their internal structure and properties. However, existing methods for quenching ring forgings still present some problems:

[0003] The quenching efficiency is low. In the existing process of quenching ring forgings, many still use traditional fire heating methods. This heating forging method not only has low heating efficiency, but also causes the temperature around the ring forgings to rise due to prolonged contact with flames, increasing the risk of burns to workers handling the ring forgings. Furthermore, it can only handle a limited number of ring forgings at a time, and cannot quench multiple ring forgings simultaneously. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quenching device for ring forgings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quenching device for ring forgings includes a quenching shell. A rectangular notch is formed through one inner wall of the quenching shell, and a fixing plate is snapped onto the inner wall of the rectangular notch. Electromagnetic heating coils are evenly distributed on the fixing plate, and a drain pipe is connected to the bottom inner wall of the quenching shell. A first electric telescopic rod is fixed to one outer wall of the quenching shell by bolts, and a fixing block is welded to the top outer wall of the first electric telescopic rod. A second electric telescopic rod is fixed to the middle of the outer wall of the fixing block near the quenching shell by screws. A connecting plate is connected to the piston rod of the second electric telescopic rod, and a guide groove is formed on the top outer wall of the connecting plate at equal intervals. A guide block is slidably connected to the inner wall of the guide groove, and a servo cylinder is connected to the top outer wall of the guide block.

[0007] As a further improvement of this utility model: a cooling water pipe is fixed to the top of the inner wall of the quenching shell on the side away from the fixed plate by screws, and spray heads distributed at equal intervals are screwed onto the cooling water pipe.

[0008] As a further improvement of this utility model: the inner wall of the bottom of the rectangular notch has a positioning slot, and the outer wall of the bottom of the fixing plate is welded with symmetrically distributed positioning blocks, which are adapted to the positioning slot.

[0009] As a further embodiment of this utility model: an arc-shaped clamping block is welded to the outer wall of the bottom of the guide block, and an anti-slip protrusion is provided on the inner wall of the arc-shaped clamping block.

[0010] As a further embodiment of this utility model: the connecting plate has symmetrically distributed guide holes through its side along the length direction, and a guide rod is slidably inserted into the inner wall of the guide hole, and the guide hole and the guide rod form an insertion fit.

[0011] As a further improvement of this invention: the guide groove is located directly above the electromagnetic heating coil, and the spacing between the guide grooves is the same as the spacing between the electromagnetic heating coils.

[0012] Compared with the prior art, the present invention provides a quenching device for ring forgings, which has the following beneficial effects:

[0013] 1. The ring forging quenching device designed in this paper can adjust the spacing of the bottom arc-shaped clamping blocks by controlling the extension and retraction of the servo cylinder, thereby clamping and fixing ring forgings of different sizes. This avoids the risk of burns caused by manual clamping by workers, and can clamp three ring forgings at the same time, greatly improving the processing efficiency of ring forgings.

[0014] 2. The ring forging quenching device designed in this paper utilizes the conductive heating of an electromagnetic heating coil to effectively improve the heating efficiency during the quenching process of the ring forging. After the heating is completed, cold water is sprayed from a spray head to quickly achieve cooling and quenching, making the operation simple.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1:

[0022] A quenching device for ring forgings, as described in this embodiment, Figure 1-3 As shown, the device includes a quenching shell 1. A rectangular notch 2 is formed through one inner wall of the quenching shell 1, and a fixing plate 3 is snapped onto the inner wall of the rectangular notch 2. Electromagnetic heating coils 4 are evenly distributed on the fixing plate 3. A drain pipe 5 is connected to the bottom inner wall of the quenching shell 1. A first electric telescopic rod 8 is fixed to one outer wall of the quenching shell 1 by bolts. A fixing block 9 is welded to the top outer wall of the first electric telescopic rod 8. A second electric telescopic rod 10 is fixed to the middle of the outer wall of the fixing block 9 near the quenching shell 1 by screws. A connecting plate 11 is connected to the piston rod of the second electric telescopic rod 10. A guide groove 14 is formed on the top outer wall of the connecting plate 11, and a guide block 15 is slidably connected to the inner wall of the guide groove 14. A servo cylinder 16 is connected to the top outer wall of the guide block 15.

[0023] By controlling the extension and retraction of the servo cylinder 16, the spacing of the bottom arc-shaped clamping block 17 can be adjusted, thereby enabling the clamping and fixing of ring forgings of different sizes. This avoids the risk of burns caused by manual clamping by workers, and can clamp three ring forgings at the same time, greatly improving the processing efficiency of ring forgings.

[0024] The crushing assembly includes a crushing box 7 and a housing 21. The crushing box 7 is welded to the top outer wall of the feeding box 2, and the housing 21 is welded to the outer side wall of the feeding box 2. Two sets of rotating rods 18 are rotatably connected to the inner wall of the crushing box 7. Crushing rollers 17 are welded to the outer side wall of the rotating rods 18. A gear 19 is welded to one end of the rotating rod 18. The two sets of gears 19 mesh with each other. A second motor 20 is fixed to the bottom inner wall of the housing 21 by bolts. The output end of the second motor 20 is fixed to a set of gears 19.

[0025] The top of the inner wall of the quenched shell 1 away from the fixed plate 3 is fixed with a cooling water pipe 6 by screws, and spray nozzles 7 are screwed on the cooling water pipe 6 at equal intervals. The bottom inner wall of the rectangular notch 2 has a positioning slot, and the bottom outer wall of the fixed plate 3 is welded with symmetrically distributed positioning blocks, which are adapted to the positioning slot.

[0026] The guide block 15 has an arc-shaped clamping block 17 welded to its bottom outer wall, and the inner wall of the arc-shaped clamping block 17 is provided with anti-slip protrusions.

[0027] When quenching ring forgings, the conductive heating of the electromagnetic heating coil 4 can effectively improve the heating efficiency. After the heating is completed, cold water is sprayed from the spray head 7 to quickly achieve cooling and quenching. The operation is simple.

[0028] In this embodiment, the fixing plate 3 connected to the electromagnetic heating coil 4 is first fixed to one side of the quenching shell 1. Then, the cooling water pipe 6 is connected to the external cooling water. Next, the ring forgings to be heated are placed at equal intervals on one side of the quenching shell 1. Then, the first electric telescopic rod 8 is retracted to drive the bottom arc-shaped clamping block 17 to descend. When it moves to the outer wall of the ring forging, the servo cylinder 16 drives the bottom arc-shaped clamping blocks 17 to move closer to each other, thereby clamping and fixing the ring forging. After clamping, the first electric telescopic rod 8 and the second electric telescopic rod 10 are used to adjust the ring forging to be directly above the electromagnetic heating coil 4. Then, the electromagnetic heating coil 4 is activated, and the ring forging is slowly lowered and inserted into the inner wall of the electromagnetic heating coil 4 to complete the heating treatment. When cooling is required after heating, cold water is sprayed using the spray head 7 to complete the rapid quenching treatment.
