Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a cooling device for automotive parts processing. Background Technology

[0002] Quenching is a metal heat treatment process that involves heating a metal workpiece to a suitable temperature and holding it for a period of time, followed by rapid cooling by immersion in a quenching medium. Commonly used quenching media include brine, water, mineral oil, and air. Quenching can improve the hardness and wear resistance of metal workpieces, and is therefore widely used in various tools, molds, measuring instruments, and parts requiring wear resistance (such as gears, rolls, carburized parts, etc.).

[0003] Some automotive parts, such as automotive gears, automotive valve plates, automotive steering knuckles, and automotive control arms, require a quenching process during production. This involves immersing the cast high-temperature workpiece in a quenching medium for rapid cooling to achieve the purpose of quenching.

[0004] In existing technologies, during quenching, workers use clamping tools to hold the high-temperature workpiece and immerse it in the quenching tank. After cooling, the workpiece is then clamped out of the quenching medium using the clamping tools. Although this method can achieve the purpose of clamping out the workpiece, if the worker makes a mistake during the clamping process, the workpiece may fall, resulting in clamping failure and splashing of the quenching medium. At the same time, when there are a large number of workpieces to be quenched, manually clamping out each workpiece is slow and wastes a lot of work, which has certain limitations in practical use. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for processing automotive parts, which can automatically remove the cooled workpiece from the quenching medium, effectively improving the convenience of workpiece removal.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A cooling device for processing automotive parts includes a cooling pool and multiple partition plates arranged parallel to each other at the top of the cooling pool. The partition plates divide the cooling pool into multiple cooling chambers, and a placement plate is slidably disposed in each cooling chamber. The cooling pool is also provided with a driving assembly for driving each placement plate to perform vertical displacement. Multiple leakage holes are vertically provided on each placement plate. The length direction of the partition plate is parallel to the vertical plane containing one set of mutually parallel sides of the cooling pool.

[0008] Preferably, the drive assembly includes hydraulic rods disposed on the partition plate and on two side walls parallel to the length direction of the cooling pool and the partition plate; in each cooling chamber, the placement plate is connected to the two hydraulic rods disposed above it via L-shaped partition plates.

[0009] Preferably, each of the placement plates is provided with a slider on its side wall, and the inner wall of the cooling chamber is provided with a vertical groove that slides in cooperation with the slider.

[0010] Preferably, each of the placement plates is surrounded by a baffle, and the baffle is provided with a plurality of the leakage holes.

[0011] Preferably, at least one side wall of the baffle is hinged to the edge of the placement plate, and the hinged side wall is connected to the remaining side wall of the baffle by a limiting component.

[0012] Preferably, the limiting component includes screw holes disposed at both ends of the hinged sidewall, and a screw rod disposed on the remaining sidewall of the baffle and adapted to the screw holes.

[0013] Preferably, the cooling pool has a first liquid outlet pipe on its side wall, a filter box at the outlet end of the first liquid outlet pipe, a second liquid outlet pipe on the filter box, and a valve on the first liquid outlet pipe.

[0014] Preferably, a limiting plate is provided around the inner wall of the filter box, and a filter screen is provided on the limiting plate. The filter screen is slidably connected to the inner wall of the filter box, and a handle is provided at the top of the filter screen. A top cover is provided at the top of the filter box, and when the top cover is closed, the top of the handle abuts against the top cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] By setting multiple parallel partition plates at the top of the cooling pool, the cooling pool can be divided into multiple cooling chambers, and high-temperature workpieces can be cooled in different cooling chambers.

[0017] By setting a placement plate in each cooling chamber and a drive device that drives the placement plate to move vertically independently in the vertical direction, the high-temperature workpiece can be placed on the placement plate, and the placement plate can be driven to move downward by the drive assembly, thereby achieving the purpose of quenching the high-temperature workpiece. After quenching, the placement plate can be driven to move upward by the drive device, thereby achieving the purpose of uniformly removing the workpieces on the placement plate from the quenching medium.

[0018] Compared to existing technologies that individually remove each workpiece from the quenching medium on the placement plate, this invention allows all workpieces located on the same placement plate to be removed from the quenching medium at the same time, which is more convenient and efficient.

[0019] Furthermore, if only a single placement plate is used in the cooling tank, all workpieces can only be placed on that plate. When one workpiece needs to be removed, the others will also be removed from the quenching medium. If the quenching time of the other workpieces differs from that of the removed workpiece, removing the other workpieces will adversely affect their quenching quality. Therefore, this invention uses multiple placement plates, allowing workpieces to be placed on different plates to accommodate the varying quenching times of the workpieces on different plates, thus improving the flexibility of the quenching process.

Detailed Implementation

[0026] Example 1

[0027] A cooling device for processing automotive parts, such as Figure 1-2 As shown, it includes a cooling pool 1 and multiple partition plates 4 arranged parallel to each other at the top of the cooling pool 1. The partition plates 4 divide the cooling pool 1 into multiple cooling chambers (which can be understood as the cooling pool 1 being divided into multiple chambers when the bottom end of the partition plate 4 extends to the bottom end of the cooling pool 1). A placement plate 2 is slidably disposed in each cooling chamber. The cooling pool 1 is also provided with a driving assembly for driving each placement plate 2 to perform vertical displacement. Multiple leakage holes 3 are vertically inserted on each placement plate 2. The length direction of the partition plate 4 is parallel to the vertical plane containing one set of mutually parallel sides of the cooling pool 1. Further, as... Figure 1-2As shown, the drive assembly includes hydraulic rods 5 disposed on the partition plate 4 and on two side walls parallel to the length direction of the cooling pool 1 and the partition plate 4; in each cooling chamber, the placement plate 2 is connected to the two hydraulic rods 5 disposed above it via L-shaped connecting plates 6. Further, as... Figure 2 As shown ( Figure 1 (The slider 7 and vertical groove 8 are not shown in the figure) Each of the placement plates 2 is provided with a slider 7 on its side wall, and the inner wall of the cooling chamber is provided with a vertical groove 8 that slides with the slider 7.

[0028] Working principle: First, by activating the hydraulic rod 5, the placement plate 2 on which the high-temperature workpiece is to be placed is moved upward until it is above the quenching medium. During the movement, the slider 7 slides in the vertical slide groove 8, and then clamps the high-temperature workpiece to be cooled on the placement plate 2. It is best to place high-temperature workpieces of the same batch or with the same cooling time on the same placement plate 2 so that workpieces of the same batch or with the same cooling time can be removed from the quenching medium together after quenching.

[0029] Once the workpiece on a placement plate 2 is placed, the hydraulic rod 5 retracts, causing the placement plate 2, along with the high-temperature workpiece at its top, to move downwards until it is inside the quenching medium. Normal cooling can then proceed.

[0030] After cooling is complete, the hydraulic rod 5 is used to move the placement plate 2 and the workpiece at its top upwards until the quenching medium is removed, and then the workpiece is transferred to the next process.

[0031] If there are multiple batches of workpieces or a large number of workpieces that need to be cooled, they can be placed on multiple placement plates 2 and added to the cooling pool 1 for cooling.

[0032] Example 2

[0033] Based on Example 1, such as Figure 3-4 As shown, each of the placement plates 2 is surrounded by a baffle 9 to prevent workpieces placed on the placement plate 2 from falling off the edge of the placement plate 2 during their up-and-down movement in the cooling pool. The baffle 9 is provided with multiple drainage holes 3 (not shown in the figure) to ensure smooth flow of the quenching medium.

[0034] Because the baffle 9 blocks the edge of the placement plate 2, after cooling, it is difficult to transfer the workpiece from the placement plate 2 to the next process by directly pushing the workpiece along one edge of the placement plate 2 to the transfer device. The workpiece can only be transferred by clamping or picking it up. Therefore, if... Figure 4As shown, at least one side wall of the baffle 9 is hinged to the edge of the placement plate 2. This allows the hinged side wall (here, the hinged side wall is referred to as the rotating plate for ease of subsequent description) to be rotated directly when a workpiece needs to be pushed. After rotation, the top edge of the side of the placement plate 2 where the rotating plate is located is not obstructed, thus allowing the workpiece to be directly pushed into the transfer device. The hinged side wall (i.e., the rotating plate) is connected to the remaining side wall of the baffle 9 via a limiting assembly. Furthermore, the limiting assembly includes screw holes (existing technology, not shown in the figure) at both ends of the hinged side wall (i.e., the rotating plate), and a screw 10 located on the remaining side wall of the baffle 9 and adapted to the screw holes. Figure 4 As shown, when it is necessary to push the workpiece, the screw 10 is moved out of the screw hole to facilitate the rotation of the rotating plate. When cooling is required, the screw 10 is moved into the screw hole to fix the rotating plate on the remaining baffle 9.

[0035] Example 3

[0036] Based on Embodiment 1 or Embodiment 2, the cooling pool 1 has a first outlet pipe 11 on its side wall, a filter box 12 at the outlet end of the first outlet pipe 11, a second outlet pipe 13 on the filter box 12, and a valve and a water pump (both prior art, not shown in the figure) on the first outlet pipe 11. Furthermore, a limiting plate 14 surrounds the inner wall of the filter box 12, a filter screen 15 is mounted on the limiting plate 14, the filter screen 15 is slidably connected to the inner wall of the filter box 12, and a handle 16 is provided at the top of the filter screen 15; a top cover 17 is provided at the top of the filter box 12, and when the top cover 17 is closed, the top of the handle 16 abuts against the top cover 17.

[0037] Working principle: When the quenching medium in cooling tank 1 needs to be replaced, the water pump is started and the valve is opened. Under the action of the water pump, the quenching medium in cooling tank 1 enters the filter box 12 along the first outlet pipe 11, is filtered by the filter screen 15, and is then discharged along the second outlet pipe 13. The quenching medium contains some metal shavings, which remain on the filter screen 15 during filtration. When these metal shavings need to be collected, the top cover 17 is opened directly, and the handle 16 is pulled upwards. This moves the filter screen 15 upwards until it is removed from the filter box 12, allowing the remaining metal shavings on the filter screen 15 to be collected or processed.
