Description

Technical Field

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

[0002] Quenching is a heat treatment process for metals or glass. It involves heating a solid material to a specified temperature range and then rapidly cooling it. In forging, quenching is also used to improve the physical properties of forgings and increase their hardness or wear resistance as needed.

[0003] For example, Chinese invention patent application CN202411152862.6 discloses a quenching device for improving the processing efficiency of forgings. The device includes a connecting box and, by setting up a movable sliding plate, an adjusting groove, and an adjusting rod, enables the second jacking plate to move when the closed plate moves outward, driving the first jacking plate and the movable sliding plate. The movable sliding plate, in turn, moves the adjusting rod and a sliding adjusting plate via the internal adjusting groove. The sliding adjusting plate, in turn, drives the L-shaped top frame and the top plate to push the forgings heated on the sliding support plate. The forgings are then guided to the quenching receiving box by a guide plate for quenching. By setting up a lead screw and an adjusting support column, the lead screw rotation drives the outer adjusting support column and the top support frame to adjust the height of the quenching receiving box. The forgings in the quenching receiving box then enter the quenching water tank for quenching.

[0004] The aforementioned document describes how the movement of components pushes the forging into the quenching receiving box, avoiding the need for workers to move it back and forth. However, the document also describes how the quenching receiving box is used to support the forging, resulting in a fixed position for the forging and only a certain range of coolant for quenching. This makes it difficult to quench the forging evenly in different parts. Therefore, this utility model is proposed. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a quenching device for forgings, which can actively drive the forgings to move in the quenching pool and place the forgings on the connecting crossbar. The outer limit wheel and inner limit wheel located on both sides can be used to limit the movement trajectory of the forgings.

[0006] The technical solution adopted by this utility model is as follows: it includes a quenching pool filled with coolant, a central cylinder fixed at the bottom of the quenching pool, a bearing assembly installed between the outer wall of the central cylinder and the inner wall of the quenching pool, the bearing assembly mainly used to support the weight of the forging and provide a transportation function, the bearing assembly includes a bearing column whose first end is rotatably engaged with the inner wall of the quenching pool, a bearing roller fixed on the outer wall of the bearing column, a second end of the bearing column passing through the central cylinder, and a helical gear fixed to the second end of the bearing column, a power mechanism provided inside the central cylinder, and a basket assembly provided above the bearing roller.

[0007] Preferably, in order to improve the stability of the basket assembly's movement, an auxiliary device is installed on the inner wall of the quenching pool between the load-bearing components. The auxiliary device includes a tube fixed to the inner wall of the quenching pool, a through-hole cylinder rotatably connected to the outer wall of the tube, a liquid permeation hole on the outer wall of the through-hole cylinder, and a spray outlet on the outer wall of the tube corresponding to the position of the through-hole cylinder.

[0008] Preferably, in order to facilitate the addition of coolant around the forging, one end of the pipe is fixed with a support plate, the bottom of the support plate is fixed to the bottom of the quenching tank, and one end of the pipe extends outside the quenching tank and is connected to a coolant source.

[0009] Preferably, in order to facilitate the rotation of the support column in the quenching tank, the power mechanism includes a power motor fixed to the bottom of the central cylinder, a drive disk fixed on the output shaft of the power motor, the edge of the drive disk being rotatably engaged with the inner wall of the central cylinder, and a drive gear ring corresponding to the helical gear at the bottom of the drive disk, the helical gear and the drive gear ring being dynamically engaged.

[0010] Preferably, in order to facilitate support of the forging and allow coolant to flow through, the basket assembly includes a pair of vertical base plates, an intermediate plate fixed between the vertical base plates, a connecting crossbar fixed between the vertical base plates, side frames fixed on the vertical base plates, and a lifting rod fixed between the side frames.

[0011] Preferably, in order to facilitate limiting the movement trajectory of the forging, an outer limiting plate is fixed on the side frame near the inner wall of the quenching tank, and an outer limiting wheel is rotatably installed on the outer limiting plate. An inner limiting plate is fixed on the side frame near the outer wall of the central cylinder, and an inner limiting wheel is rotatably installed on the inner limiting plate.

[0012] Preferably, in order to facilitate the removal and placement of the basket assembly, a removal mechanism is fixed on the central cylinder. The removal mechanism includes a central column, a horizontal plate is fixed to the top of the central column, a lifting telescopic rod is fixed to the bottom of the horizontal plate, and a locking hook plate is fixed to the bottom of the lifting telescopic rod. In order to prevent the lifting rod from falling off, a lower protruding strip can be provided at the bottom of the lifting rod, and a locking groove can be provided on the locking hook plate.

[0013] The beneficial effects of this utility model are: this quenching device can actively move the forging in the quenching tank and place the forging on the connecting crossbar. The outer and inner limit wheels on both sides can be used to limit the movement trajectory of the forging. Moreover, the take-up mechanism can lift the basket assembly together with the forging when needed, improving processing efficiency. In use, the forging is placed on the connecting crossbar, and then the telescopic rod extends to place the forging and the basket assembly in the quenching tank. Then, the power motor can drive the helical gear to rotate through the drive disc, thereby causing the bearing roller to drive the basket assembly to move, thereby moving the forging, so that the relatively flowing coolant can perform uniform quenching treatment on the forging.

[0024] An auxiliary device 5 is installed on the inner wall of the quenching pool 1 between the load-bearing components 2. The auxiliary device 5 includes a tube 501 fixed on the inner wall of the quenching pool 1. A through-hole cylinder 502 is rotatably connected to the outer wall of the tube 501. A liquid permeation hole is provided on the outer wall of the through-hole cylinder 502. A spray outlet is provided on the outer wall of the tube 501 at the position corresponding to the through-hole cylinder 502. This can improve the stability of the movement of the basket assembly 4.

[0025] One end of the tube body 501 is fixed with a support plate 503. The bottom of the support plate 503 is fixed to the bottom of the quenching pool 1. One end of the tube body 501 extends to the outside of the quenching pool 1 and is connected to a coolant source, which makes it easy to add coolant around the forging.

[0026] The power mechanism 3 includes a power motor 301 fixed at the bottom of the center cylinder 101. A drive disk 302 is fixed on the output shaft of the power motor 301. The edge of the drive disk 302 is rotatably engaged with the inner wall of the center cylinder 101. A drive gear ring 303 is provided at the bottom of the drive disk 302 corresponding to the helical gear 203. The helical gear 203 and the drive gear ring 303 are engaged in power, which facilitates the rotation of the support column 201 in the quenching pool 1.

[0027] The basket assembly 4 includes a pair of vertical base plates 401, a middle plate 402 fixed between the vertical base plates 401, a connecting crossbar 403 fixed between the vertical base plates 401, a side frame 404 fixed on the vertical base plates 401, and a lifting rod 405 fixed between the side frames 404.
