Description

Technical Field

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

[0002] Quenching oil is a medium that is added to a quenching oil bath to rapidly cool down the workpiece after quenching.

[0003] In the prior art, according to patent application number CN201921302754.7, a stirring device for a quenching oil bath is disclosed. This device installs a first stirring shaft and a second stirring shaft in the quenching oil bath. By controlling the rotation of the stirring shafts, the flowability of the quenching oil is accelerated, allowing the high-temperature quenching oil surrounding the workpiece to mix and exchange heat with the cooling oil in other areas of the quenching oil bath, thus achieving the desired cooling effect. However, because the quenching oil is in a fluid state, the workpiece placed in the bath will also float relative to the oil bath. When the workpiece, which has not yet cooled and solidified, comes into contact with the rotating stirring shaft, it can easily cause damage to both the stirring shaft and the workpiece.

[0004] To address the aforementioned shortcomings, a mixing device for quenching oil is provided. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for quenching oil in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mixing device for quenching oil, comprising a quenching oil tank, wherein two baffles are slidably connected inside the quenching oil tank, and a first stirring shaft is rotatably connected to the outer end of the baffles via a frame plate; a first driving component is provided on the quenching oil tank to control the synchronous movement of the two baffles; a second driving component is provided in the quenching oil tank to control the synchronous rotation of the two first stirring shafts; a second stirring shaft is also rotatably connected in the quenching oil tank; a drive motor for controlling the rotation of the second stirring shaft is installed at the outer end of the quenching oil tank; and a partition is fixedly provided inside the quenching oil tank above the second stirring shaft.

[0007] Preferably, the quenching oil bath has two opposing grooves.

[0009] Preferably, the second driving component includes a bracket fixed to the side end of the frame plate, a second bevel tooth rotatably connected to the bracket, and an assembly for driving the second bevel tooth to rotate. The side end of the frame plate is rotatably connected to a first bevel tooth fixed coaxially with the first stirring shaft, and the first bevel tooth meshes with the second bevel tooth.

[0010] Preferably, the component that drives the second bevel tooth to rotate includes a rotating shaft rotatably connected in the groove and coaxially distributed with the second bevel tooth, and a first motor for controlling the rotation of the rotating shaft is installed at the outer end of the quenching oil bath.

[0011] Preferably, the inner end of the second bevel tooth is fixed with a strip tooth, and a strip groove is formed on the side wall of the rotating shaft to slide with the strip tooth.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this application, by setting baffles and partitions, the quenched workpiece in a red-temperature state is prevented from contacting the first stirring shaft or the second stirring shaft after being placed in the quenching oil bath, thereby playing a protective role for the first stirring shaft, the second stirring shaft and the quenched workpiece.

[0014] 2. In this application, by adjusting the spacing between the two baffles, the spacing between the two baffles is made to match the size and width of the workpiece to be quenched. When the workpiece is placed in the quenching oil bath, the two first stirring shafts rotate to accelerate the flow of quenching oil around the workpiece, thereby satisfying the need for rapid cooling of the quenched workpiece.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a mixing device for quenching oil, including a quenching oil tank 1, with two baffles 2 slidably connected inside the quenching oil tank 1, and a first stirring shaft 4 rotatably connected to the outer end of the baffles 2 via a frame plate 3. A first driving component is provided on the quenching oil tank 1 to control the synchronous movement of the two baffles 2, and a second driving component is provided in the quenching oil tank 1 to control the synchronous rotation of the two first stirring shafts 4. A second stirring shaft 13 is also rotatably connected in the quenching oil tank 1, and a drive motor for controlling the rotation of the second stirring shaft 13 is installed at the outer end of the quenching oil tank 1. A partition plate 14 is fixedly provided inside the quenching oil tank 1 on the upper side of the second stirring shaft 13. Two opposing grooves 101 are formed in the quenching oil tank 1.

[0023] The first driving component controls the synchronous movement of the two baffles 2, adjusting the distance between them to match the width of the workpiece to be quenched. After the workpiece is placed in the quenching oil bath 1, the second driving component controls the rotation of the two first stirring shafts 4 to accelerate the flow of quenching oil around the workpiece. This allows the quenching oil with its increased temperature to mix and exchange heat quickly with the quenching oil on the outer side of the quenching oil bath 1, thereby achieving rapid cooling of the quenched workpiece.

[0024] By setting the baffle 2 and the partition 14, the quenched workpiece in the red-temperature state is prevented from contacting the first stirring shaft 4 or the second stirring shaft 13 after being placed in the quenching oil bath 1, thereby playing a protective role for the first stirring shaft 4, the second stirring shaft 13 and the quenched workpiece.

[0025] Specifically, such as Figure 2 and Figure 3As shown, the first driving component includes a bidirectional screw 11 rotatably connected in the groove 101. A second motor 12 for controlling the rotation of the bidirectional screw 11 is installed at the outer end of the quenching oil tank 1. A threaded sleeve 10 that is screwed into the bidirectional screw 11 is fixed at the side end of the frame plate 3. The second motor 12 is started to control the rotation of the bidirectional screw 11, so that the threaded sleeve 10 that is screwed into the bidirectional screw 11 drives the baffle 2 fixed to the frame plate 3 to move along the quenching oil tank 1, thereby adjusting the distance between the two baffles 2.

[0026] Specifically, such as Figure 2-4 As shown, the second driving component includes a bracket 6 fixed to the side end of the frame plate 3, a second bevel tooth 7 rotatably connected to the bracket 6, and an assembly for driving the second bevel tooth 7 to rotate. The side end of the frame plate 3 is rotatably connected to a first bevel tooth 5 fixed coaxially with the first stirring shaft 4, and the first bevel tooth 5 meshes with the second bevel tooth 7. The assembly for driving the second bevel tooth 7 to rotate includes a rotating shaft 8 rotatably connected in the groove 101 and coaxially distributed with the second bevel tooth 7. A first motor 9 for controlling the rotation of the rotating shaft 8 is installed at the outer end of the quenching oil tank 1. A strip tooth 701 is fixed to the inner end of the second bevel tooth 7, and a strip groove 801 is formed on the side wall of the rotating shaft 8 to slide with the strip tooth 701.

[0027] The first motor 9 is started to control the rotation of the rotating shaft 8, which causes the second bevel tooth 7, which slides coaxially with the rotating shaft 8, to drive the first bevel tooth 5, which meshes with it, to rotate. This, in turn, causes the first stirring shaft 4, which is fixed coaxially with the first bevel tooth 5, to rotate. Through the cooperation between the strip tooth 701 and the strip groove 801, the rotating shaft 8 can drive the second bevel tooth 7, which is slidably connected to it, to rotate.

[0028] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
