Description

Technical Field

[0001] This utility model relates to the field of oiling device technology, and more specifically, to an oiling device for powder metallurgy workpieces. Background Technology

[0002] Powder metallurgy, as a highly efficient material preparation and parts forming technology, occupies an important position in modern manufacturing. Workpieces prepared by this process, due to their internal porous structure, usually require oil immersion treatment (i.e., "oiling") after the high-temperature sintering process. The core purpose of this process is to utilize the permeability of oil to fill the micropores inside the workpiece, thereby significantly improving the wear resistance, corrosion resistance, self-lubricating properties, and overall service life of the workpiece. It is a key post-processing step to ensure the final quality and reliability of powder metallurgy workpieces.

[0003] On the one hand, the oiling devices commonly used in the industry are relatively simple in structure, mainly consisting of an open immersion tank. The workpieces are usually placed in a metal mesh basket or material frame. Operators manually or with the help of simple lifting equipment such as cranes lift the basket to the top of the immersion tank, and then slowly immerse it in the oil for a certain period of time to ensure the penetration effect. After the immersion is completed, the basket full of workpieces is lifted out of the oil tank as a whole and transferred to the dripping area for draining. The primary problem exposed by this traditional operation mode in practice is that there are many manual operation steps, low efficiency and high labor intensity. Every loading and unloading requires manual intervention: lifting in, positioning, timing, lifting out, transferring and draining. Especially when the batch is large or the workpieces themselves have a certain weight, the operation process is not only time-consuming and labor-intensive.

[0004] On the other hand, during the process of lifting the workpiece basket away from the oil tank, a large amount of oil will be carried out with it, and continuous dripping will occur in the transfer path and dripping area, resulting in the actual consumption of rust-preventive oil being far higher than the theoretical amount required to effectively penetrate into the pores of the workpiece.

[0005] Therefore, existing oil-passing devices need improvement in terms of unloading methods and oil consumption. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an oiling device for powder metallurgy workpieces, thereby solving the technical problems of low manual unloading efficiency and high oil consumption during the oil immersion process in existing oiling devices.

[0007] The purpose and effect of this utility model for an oiling device for powder metallurgy workpieces are achieved by the following specific technical means:

[0008] An oiling device for powder metallurgy workpieces includes an oiling tank, an oiling frame, and an oil draining tank. One end of the oiling tank is connected to the oil draining tank. An oil draining screen is installed inside the oil draining tank. An oil pump is installed on one side of the oil draining tank. The oiling frame is installed inside the oiling tank. Two sets of connecting parts are connected to both sides of the oiling frame. A slidable baffle is installed at one end of the oiling frame. A support frame is installed inside the oiling tank.

[0009] A mounting bracket is provided at one end of the oil tank, a drive motor is mounted on the top of the mounting bracket, a screw is connected to the main shaft of the drive motor, and a sliding plate is provided on the mounting bracket.

[0010] According to a preferred embodiment, two sets of first sliding grooves are symmetrically arranged inside the oil tank, and one end of each set of the connecting members is respectively locked in the two sets of first sliding grooves.

[0011] The oil tank is equipped with a first connecting rod, one end of which is rotatably connected to the baffle.

[0012] According to a preferred embodiment, a first connecting plate is provided on both sides of the oil passage frame, and a second connecting plate is provided on both sides of the oil passage tank. Two sets of electric telescopic rods are respectively connected between the two sets of first connecting plates and the two sets of second connecting plates.

[0013] According to a preferred embodiment, two sets of second sliding grooves are respectively opened on both sides of the mounting frame, and the two ends of the sliding plate are respectively engaged in the two sets of second sliding grooves.

[0014] According to a preferred embodiment, two sets of first connecting blocks are integrally formed on one side of the sliding plate, and two sets of second connecting blocks are fixedly connected to one end of the oil-passing frame. A second connecting rod is connected to each of the two sets of first connecting blocks, and one end of each of the two sets of second connecting rods is rotatably connected to the two sets of second connecting blocks respectively.

[0015] According to a preferred embodiment, a threaded hole is provided through the top of the sliding plate, and the screw is inserted into the threaded hole.

[0016] According to a preferred embodiment, an oil inlet is provided on one side of the oil tank, and an oil delivery pipe is connected to one end of the oil pump, with one end of the oil delivery pipe connected to the oil inlet.

[0017] According to a preferred embodiment, the bottom of the oil-passing frame has multiple sets of through holes, and the periphery of the oil-passing frame has multiple sets of through grooves.

[0018] Based on the above aspects, this utility model has the following beneficial effects:

[0019] First, the user can start the drive motor to rotate the screw, which in turn moves the sliding plate upward along the mounting bracket. The second connecting rod lifts one end of the oil-passing frame. After being lifted to a certain angle, the end of the oil-passing frame connected to the connector will move upward along the first sliding groove, eventually tilting the workpiece inside the oil-passing frame with one end higher than the other. At the same time, during the lifting process of the oil-passing frame, the first connecting rod, which is fixed inside the oil-passing tank, will pull the baffle, causing the baffle to slide downward relative to the oil-passing frame. This allows the workpiece inside the oil-passing frame to be smoothly poured into the oil-draining tank, reducing the fatigue of the workers during unloading.

[0020] Secondly, the workpieces are drained on the oil draining net in the oil draining tank. The oil drips into the bottom of the oil draining tank. When the oil level in the oil draining tank reaches a certain height, the user can use an oil pump to pump the oil in the oil draining tank back into the oil tank through the oil delivery pipe, reducing the amount of oil lost. At the same time, the support frame supports the oil passing frame, and impurities on the surface of the workpiece fall into the bottom of the oil passing tank through the through hole at the bottom of the oil passing frame, preventing impurities from entering the pores of the next batch of workpieces, thus improving the practicality of the device.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0029] As attached Figure 1 To be continued Figure 5 As shown:

[0030] An oiling device for powder metallurgy workpieces includes an oiling tank 100, an oiling frame 101, and an oil draining tank 102. The oiling tank 100 is used to hold oil, the oiling frame 101 is used to load the workpieces to be oiled, and the oil draining tank 102 collects the oil during the draining process. One end of the oiling tank 100 is connected to the oil draining tank 102. An oil draining screen 103 is installed inside the oil draining tank 102, and an oil pump 104 is installed on one side of the oil draining tank 102. The oiling frame 101 is installed inside the oiling tank 100. Two sets of connectors 105 are connected to each side. A sliding baffle 106 is provided at one end of the oil-passing frame 101. The baffle 106 can be slidably retracted to facilitate the smooth entry of the workpiece into the oil-draining tank 102. A support frame 107 is provided inside the oil-passing tank 100. The support frame 107 can support the oil-passing frame 101. During the oil-passing process, impurities on the surface of the workpiece settle to the bottom of the oil-passing tank 100. Supporting the oil-passing frame 101 can prevent the workpiece from contacting the impurities at the bottom of the oil-passing tank 100, thereby improving the oil-passing quality.

[0031] An installation bracket 108 is provided at one end of the oil tank 100. A drive motor 109 is installed on the top of the installation bracket 108. A screw 110 is connected to the main shaft of the drive motor 109. A sliding plate 111 is provided on the installation bracket 108.

[0032] The mounting bracket 108 has two sets of second sliding grooves 117 on both sides. The two ends of the sliding plate 111 are respectively locked in the two sets of second sliding grooves 117. The top of the sliding plate 111 has a threaded hole through which a screw 110 passes.

[0033] Two sets of first connecting blocks 118 are integrally formed on one side of the sliding plate 111. Two sets of second connecting blocks 119 are fixedly connected to one end of the oil passing frame 101. A second connecting rod 120 is connected to each of the two sets of first connecting blocks 118. One end of each of the two sets of second connecting rods 120 is rotatably connected to the two sets of second connecting blocks 119 respectively.

[0034] Understandably, the user can start the drive motor 109 to drive the screw 110 to rotate, thereby driving the sliding plate 111 to move upward along the mounting bracket 108. During the movement of the sliding plate 111, one end of the oil-passing frame 101 is lifted through the second connecting rod 120, so that the oil-passing frame 101 is in a tilting posture with one high and one low, tilting the workpiece.

[0035] Two sets of first sliding grooves 112 are symmetrically arranged inside the oil tank 100, and one end of each set of connectors 105 is respectively locked in the two sets of first sliding grooves 112.

[0036] A first connecting rod 113 is provided inside the oil tank 100. One end of the first connecting rod 113 is rotatably connected to the baffle 106. It can be understood that when the oil frame 101 is raised, the first connecting rod 113, which is fixed to the bottom of the oil tank 100, will pull the baffle 106, causing the baffle 106 to move downward relative to the oil frame 101 and retract. At this time, the workpiece can fall smoothly from the oil frame 101 into the oil draining tank 102, reducing the amount of manual labor and improving the unloading efficiency.

[0037] Both sides of the oil-passing frame 101 are provided with first connecting plates 114, and both sides of the oil-passing tank 100 are provided with second connecting plates 115. Two sets of electric telescopic rods 116 are respectively connected between the two sets of first connecting plates 114 and the two sets of second connecting plates 115. When the drive motor 109 drives one end of the oil-passing frame 101 to lift through the screw 110, sliding plate 111, etc., the two sets of electric telescopic rods 116 also lift the end of the oil-passing frame 101 away from the mounting frame 108, so that the bottom of the oil-passing frame 101 is flush with the height of the notch at one end of the oil-passing tank 100, so that the workpiece can smoothly enter the oil-draining tank 102 for the draining process.

[0038] An oil inlet 121 is provided on one side of the oil tank 100. One end of the oil pump 104 is connected to an oil delivery pipe 122, and the other end of the oil delivery pipe 122 is connected to the oil inlet 121. After the workpiece is drained on top of the oil draining screen 103 in the oil draining tank 102, the oil flows to the bottom of the oil draining tank 102. When the oil level reaches a certain height, the user can use the oil pump 104 to pump the oil back into the oil tank 100 through the oil delivery pipe 122, thereby reducing the oil loss of the device and reducing costs.

[0039] Multiple sets of through holes are formed through the bottom of the oil-passing frame 101, and multiple sets of through grooves are formed around the periphery of the oil-passing frame 101.
