[0002] A thread rolling die, also known as a thread cutting die, is a special tool for machining taps and bolts. It is widely used in the standard fastener industry for thread machining of screws and bolts.
[0003] During the processing of toothed plates, they need to be tempered to reduce or eliminate their internal stress. Existing tempering devices require manual removal of the toothed plates from the heating furnace and then placement of new toothed plates into the furnace. Due to the relatively heavy weight of the toothed plates, it is inconvenient to manually place and remove them from the heating furnace, which takes a lot of time and is difficult to meet the usage requirements. Utility Model Content
[0004] The purpose of this invention is to provide a tempering device for toothed plates, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: the toothed plate tempering device includes:
[0006] A heating furnace, with a side opening;
[0007] The placement section is used to close the side opening of the heating furnace and to place the toothed plate.
[0008] A pushing part is provided on the heating furnace, and a placing part is provided on the pushing part. The pushing part is used to control the movement of the placing part.
[0009] A drive unit is disposed on the push unit, and the drive unit is used to adjust the orientation of the placement unit.
[0010] Preferably, the placement part includes a sealing plate, and protrusions are respectively provided on both sides of the sealing plate. Several sets of support units for supporting the tooth plate are provided on the side of the protrusions. Each support unit includes two fixing rods fixed on the protrusions, and protective cylinders are installed on the outer surfaces of the two fixing rods.
[0011] Preferably, the sealing plate is connected to the heating furnace via a connector, which includes a movable part and a fixed part. The movable part is disposed on the sealing plate and rotatably connected to the sealing plate, while the fixed part is disposed on the heating furnace.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0021] like Figure 1-4 As shown, a toothed plate tempering device includes:
[0022] Heating furnace 1, with a side opening;
[0023] The placement section is used to close the side opening of the heating furnace 1 and to place the toothed plate 3.
[0024] A pushing section is provided on the heating furnace 1, and a placement section is provided on the pushing section. The pushing section is used to control the movement of the placement section.
[0025] The drive unit is located on the push unit and is used to adjust the orientation of the placement unit.
[0026] The heating furnace 1 includes a furnace cavity and a control system. The furnace cavity has a side opening, and the control system is located at the bottom of the furnace cavity. Refractory materials are provided inside the furnace cavity and on both the upper and lower sides. Grooves are opened on the refractory materials located at the top and bottom. Electric heating tubes 2 are installed inside the furnace cavity and in the upper and lower grooves. At the same time, the control system can also detect the temperature inside the furnace cavity through a temperature sensor and can control the temperature inside the furnace cavity by changing the power to meet the temperature requirements during the tempering of the toothed plate 3.
[0027] Furthermore, the placement part includes a sealing plate 4, with protrusions 5 on both sides of the sealing plate 4. Several sets of support units for supporting the toothed plate 3 are provided on the side of the protrusions 5. Each support unit includes two fixing rods 6 fixed on the protrusions 5. Protective sleeves 7 are installed on the outer surfaces of the two fixing rods 6. The fixing rods 6 are high-temperature resistant metal rods. The toothed plate 3 is made of Cr12MoV with a tempering temperature of 500℃. The high-temperature resistance of the fixing rods 6 needs to exceed this temperature to prevent the fixing rods 6 from bending. At the same time, the protective sleeve is made of refractory ceramic material.
[0028] The sealing plate 4 is made of a metal frame and refractory material. The boss 5 is made of refractory material. The boss 5 and the refractory material in the sealing plate 4 are integrated to enhance the stability of the sealing plate 4.
[0029] When the boss 5 enters the side opening of the furnace cavity, there is a gap of 2mm or more between the side of the boss 5 and the side of the opening to ensure that the boss 5 can stably enter the side opening of the furnace cavity.
[0030] Furthermore, the sealing plate 4 is connected to the heating furnace 1 by a connector, which includes a movable part 9 and a fixed part 8. The movable part 9 is disposed on the sealing plate 4 and is rotatably connected to the sealing plate 4. The fixed part 8 is disposed on the heating furnace 1. When the sealing plate 4 rotates 180°, the movable part 9 is also rotated 180° so that the movable part 9 can still be connected to the fixed part 8.
[0031] Furthermore, the pushing part includes a push plate 10, a sliding groove for the push plate 10 to move is provided on the heating furnace 1, an installation groove is provided on the heating furnace 1, an upright plate 11 is provided on the lower surface of the push plate 10, a telescopic push rod 12 is provided inside the installation groove, the output end of the push rod 12 is fixedly connected to the upright plate 11, an upright rod 13 is provided at the lower end of the sealing plate 4, the upright rod 13 is rotatably connected to the push plate 10, an installation frame 14 is provided at one end of the push plate 10, and a roller 15 is provided on the installation frame 14.
[0032] The push rod 12 can be an electric push rod 12, a pneumatic push rod 12, or a hydraulic push rod 12. When it is an electric push rod 12, it is driven by electricity. When it is a pneumatic push rod 12 or a hydraulic push rod 12, a corresponding power source needs to be configured, and a controller needs to be configured for each of the electric push rod 12, pneumatic push rod 12, and hydraulic push rod 12. The controller controls the extension and retraction of the output end of the push rod 12, and can also adjust parameters such as the moving speed of the output end of the push rod 12.
[0033] By activating push rod 12, the output end of push rod 12 extends. When the output end of push rod 12 extends, it can drive push plate 10 to move through vertical plate 11, and drive sealing plate 4 on push plate 10 to move, so that sealing plate 4 can move away from furnace cavity. When the output end of push rod 12 retracts, it can drive sealing plate 4 to move towards furnace cavity.
[0034] The mounting bracket 14 and the rollers 15 can provide support for the push plate 10, thereby ensuring the stability of the sealing plate 4 located on the push plate 10. When the push plate 10 moves, the rollers 15 can also reduce the resistance when the push plate 10 moves. A track for the movement of the rollers 15 can be installed on the ground to further improve the stability of the push plate 10 when it moves.
[0035] Furthermore, the drive unit is a motor 16, which is located below the support plate. The output end of the motor 16 is fixedly connected to the upright 13. The rotation of the output end of the motor 16 can drive the upright 13 to rotate, thereby driving the sealing plate 4 fixedly connected to the upright 13 to rotate. The sealing plate 4 rotates 180° each time, which needs to be controlled by the motor 16 to rotate the sealing plate 4 by 180°. The motor 16 can be a stepper motor 16, which controls the angle by pulse counting, or a servo motor 16, which uses closed-loop control and has built-in encoder feedback. Since controlling the output end of the motor 16 to rotate 180° is existing technology, it will not be described in detail here. In this application, since there is a gap between the boss 5 and the opening of the furnace cavity, the rotation angle of the motor 16 is allowed to have an error, which is no more than 0.5°. At the same time, a reducer can be configured between the output end of the motor 16 and the upright 13 to more accurately control the rotation angle of the output end of the motor 16.
[0036] When tempering the toothed plate 3, multiple toothed plates 3 are first placed on the protective cylinder 7 in sequence. After the toothed plates 3 are placed, the push rod 12 is activated to push the push plate 10 out of the heating furnace 1 and push the sealing plate 4 out of the heating furnace 1. After the fixing rods 6 on both sides of the sealing plate 4 are completely removed from the heating furnace 1, the sealing plate 4 is rotated 180° by the motor 16 so that the protective cylinder 7 with the toothed plates 3 is facing the opening of the heating furnace 1. Then, the push rod 12 drives the sealing plate 4 to move towards the heating furnace 1 and the toothed plates 3 enter the heating furnace 1. When the sealing plate 4 contacts the heating furnace 1, the upper part of the sealing plate 4 is connected to the heating furnace 1 by the movable part 9 and the fixed part 8, and the lower part of the sealing plate 4 is attached to the heating furnace 1 by the push plate 10.
[0037] After the toothed plate 3 enters the heating furnace 1, each toothed plate 3 has an electric heating tube 2 on both sides, so that the upper and lower sides of the toothed plate 3 can be heated at the same time to improve the uniformity of heating of the toothed plate 3.
[0038] During the heating process of the toothed plate 3 inside the heating furnace 1, a new toothed plate 3 can be placed on the sealing plate 4 and on the protective cylinder 7 outside the heating furnace 1. After the toothed plate 3 inside the heating furnace 1 has finished heating, the movable part 9 and the fixed part 8 are opened, and the toothed plate 3 is pushed out of the heating furnace 1 by the push rod 12. Then, the sealing plate 4 is rotated 180° by the motor 16 to push the new toothed plate 3 into the heating furnace 1. The heated toothed plate 3 located outside the heating furnace 1 can be transferred out. After the toothed plate 3 is transferred out, a new toothed plate 3 can be placed on the protective cylinder 7 so that it can be transferred into the heating furnace 1 later.
[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
