Description

Technical Field

[0001] The invention relates to the technical field of gear thermal processing, and in particular to an intelligently controlled gear carburizing and quenching device and a control method thereof. Background Art

[0002] In the hot working of gears, it is often necessary to perform carburizing and quenching on the gears. Carburizing and quenching is a common heat treatment process for metal materials. It can make the surface of the carburized workpiece obtain a high hardness and improve its wear resistance. The traditional processes mainly include: low temperature tempering, pre-cooling direct quenching, primary heating quenching, carburizing high temperature tempering, secondary quenching cold treatment, induction heating after carburizing and other processes. The quenching process is widely used in the modern machinery manufacturing industry. However, the gear carburizing and quenching equipment in the existing technology has poor use effect. Combining the communication and analysis of our company's actual gear carburizing and quenching processing and gear carburizing and quenching processing equipment in the same industry, the gear carburizing and quenching processing equipment in the prior art still has the following shortcomings: First, the structural design is unreasonable. The gear carburizing and quenching processing equipment in the prior art can only perform heating operations on a single model of gears. Specifically, the heights and diameters of gears of different models are different. In the traditional gear quenching and heating process, the gears are placed directly on the substrate, or a single mold is opened to provide stable support for a single series of gears. However, both methods have their own shortcomings. It is impossible to achieve stable support for the gears to be quenched, avoid repeated mold opening, and realize low-cost automatic tightening operations for gears of different specifications and models to ensure that the gears to be processed are always concentric with the induction heating copper tube.

[0003] Second, the gear carburizing and quenching processing equipment of the prior art usually uses a single-size electric induction heating copper tube for quenching and heating operations. Specifically, in order to adapt to the processing of gears of various sizes and specifications, conventional quenching and heating generally sets the electric induction heating copper tube of the maximum size. However, in the actual gear quenching operation, it is found that when the larger-sized electric induction heating copper tube is used for the quenching of smaller-sized gears, due to the existence of spatial difference distribution, the heat loss is large, and the quenching temperature of the gear to be processed often does not meet the standard, which will also cause a certain amount of defective rate in the gear processing, seriously affecting the quality and efficiency of the gear quenching processing. Third, the electric induction heating copper tubes of the prior art are directly connected to the power supply, which causes the fluctuation of the external connection voltage to have an adverse effect on the heating temperature of the electric induction heating copper tube. At the same time, the coolant below will also have a certain impact on the heating temperature of the electric induction heating copper tube, and the heating temperature fluctuation of the electric induction heating copper tube will directly affect the accuracy and quality of the gear to be processed. For this reason, we need an intelligently controlled gear carburizing and quenching equipment and its control method. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In the absence of further restrictions, the possible appearance of the sentence "including a ..." and other defined elements does not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0021] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "provided with" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] Example 1: Figures 1 to 9 As shown: A gear carburizing and quenching device with intelligent control, the gear carburizing and quenching device comprises a base 1, a heating mechanism 2 and a cooling mechanism 3. The gear carburizing and quenching device has a compact structure, a relatively short volume of the entire structure, and saves structural space. Compared with the traditional gear carburizing and quenching equipment, the length can be compressed by more than 30%, and the dynamic balance of the structure is improved; compared with the ordinary gear carburizing and quenching equipment of the same power, the utilization rate of heat resources can be increased by about 40%; at the same time, compared with the traditional gear carburizing and quenching equipment, the structure is optimized and upgraded, the operation is more convenient, and the gear quenching efficiency is increased by about 35%.

[0023] like Figure 2As shown: wherein, the base 1 is distributed on the left and right; a support leg 102 is also provided at the lower end of the base 1. The purpose of such a configuration is to ensure the stability of the base and to provide a stable foundation for the subsequent gear quenching processing. A column 101 is also provided on the rear side of the base 1, and the column 101 is vertically distributed; the column and the base are fixed by welding. The heating mechanism 2 includes a mounting seat 201, an electric induction heating copper tube 202 and a driving member 203. The mounting seat 201 is movably arranged on the column 101 up and down through the driving member 203 to complete the preset height adjustment operation required for quenching gears of different specifications and models. In a preferred technical solution, as Figure 3 As shown: the driving member 203 includes a rotating lead screw 212, a guide rod 213 and a driving motor 214. A top plate 105 is also provided at the upper end of the column 101, and the two are vertically distributed. The rotating lead screw 212 is rotatably arranged between the top plate 105 and the base 1; bearings are provided at the connection between the rotating lead screw and the two.

[0024] like Figure 3 As shown: wherein, the guide rods 213 are two and distributed on the left and right, and are also arranged between the top plate 105 and the base 1, and are arranged parallel to the rotating screw 212; the two guide rods are located on both sides of the rotating screw. The mounting seat 201 is sleeved and installed between the rotating screw 212 and the guide rod 213, and the mounting seat 201 and the rotating screw 212 are connected by a threaded rotation, and the mounting seat 201 and the guide rod 213 are connected by a sliding connection; the driving motor 214 is installed on the top plate 105 through a bracket, and the output shaft is connected to the rotating screw 212. In this way, a "screw nut" structure can be formed between the mounting seat and the rotating screw, and the driving motor is preferably a servo control motor, which is convenient for accurately controlling the movement of the mounting seat. When the driving motor starts to rotate forward, it can drive the rotating screw to rotate synchronously clockwise, thereby driving the mounting seat to move up relative to the rotating screw and the guide rod. When the drive motor starts to reverse, it can drive the rotating screw to rotate counterclockwise synchronously, thereby driving the mounting seat to move downward relative to the rotating screw. This is simple to operate and can achieve precise adjustment of the height to adapt to the quenching processing of gears of different heights and sizes.

[0025] like Figure 1 As shown: In this embodiment, the electric induction heating copper tube 202 adopts a ring-shaped electric induction hollow copper tube structure, and a connecting seat 204 is provided at one end. The electric induction heating copper tube is a prior art, and its heating principle is not described in detail. A temperature measuring probe 205 is also provided on one side of the electric induction heating copper tube 202; the temperature measuring probe is a high temperature resistant temperature measuring probe, which is used to detect the temperature of the electric induction heating copper tube in real time. Figure 4As shown: the inner cavity of the connecting seat 204 is a hollow structure, and is provided with an electric control board 206 that maintains electrical connection with the electric induction heating copper tube 202; the input end of the electric induction heating copper tube is connected to the electric control board through a wire, and the input end of the electric control board is connected to an external power supply through a wire. The connecting seat 204 and the mounting seat 201 are connected by a connector 4, so that the two can be easily disassembled, and at the same time, different preset fastening forces can be completed in the installed state. A preferred technical solution, specifically refer to Figure 4 As shown: the connecting member 4 includes a connecting column 401, a connecting sleeve 402, a clamping plate 403 and a clamping tooth 404. The connecting column 401 is arranged on the connecting seat 204 and keeps a front-to-back distribution, and the two can be fixed by welding connection; the connecting column is distributed perpendicular to the connecting seat. The connecting sleeve 402 is fixedly installed on the mounting seat 201, and an axially distributed connecting groove 410 is provided inside, and the connecting column 401 is matched and installed with the connecting groove 410. Preferably, the connecting sleeve is a structure with a square outside and a round inside, and the connecting column is a cylindrical structure. Such a configuration facilitates connection and support. For details, refer to Figure 8 The structure shown.

[0026] like Fig. 9 As shown: wherein, the clamping plate 403 is arranged on the connecting seat 204, and a connecting tooth 405 is arranged at the end thereof, and the clamping plate 403 is made of an elastic plate; the clamping plate and the connecting tooth are an integrally formed structure. The clamping tooth 404 is arranged on the outer arm of the connecting sleeve 402, and the clamping teeth 404 are multiple and spaced apart, and the connecting tooth 405 is matched and installed with the clamping teeth 404 at different positions to complete the support operation of different preset fastening forces in the installed state. For details, refer to Figure 8 The purpose of such a setting is that as the size of the electric induction heating copper tube becomes larger and larger, its weight will also become larger and larger. In order to provide it with a better, more stable and more suitable supporting connection effect, the support operation with different preset fastening forces can be completed in the installed state through the cooperation of the connecting teeth and the clamping teeth. In order to better support according to actual needs and consider the cost of manufacturing the clamping teeth, the length of the inserted connecting column cannot be too short. Therefore, Figure 4 From the perspective, the rightmost latching tooth is at an appropriate distance from the right end surface of the connecting sleeve. Figure 8 and Fig. 9 The structure shown: the connecting member 4 includes a limit bar 406 and a limit groove 407. The limit groove 407 is opened on the side wall of the connecting groove 410, and there are two limit grooves distributed on the left and right sides; the limit bar 406 is set on the connecting column 401, and the limit bar 406 is kept matched with the limit groove 407 for installation; at the same time, the limit bar 406 and the clamping plate 403 are kept perpendicular to each other in space. Fig. 9In the viewing angle, there are two limit bars distributed on the left and right, and two card plates distributed on the top and bottom. The cross section of the limit bar 406 can be any one of rectangular, square, triangular, and circular. Such a setting can provide a precise guiding installation effect.

[0027] like Figure 4 As shown: In this embodiment, the connecting member 4 also includes a spring 408 and a baffle 409; the spring 408 is installed in the connecting groove 410, and one end is connected to the inner wall of the connecting groove 410, and the other end is connected to the baffle 409, and the baffle 409 is adapted to the structure of the connecting groove 410. When the connecting column and the connecting sleeve are installed, the connecting teeth and the clamping teeth are matched and installed to form a locked position state. In the initial state, the spring is naturally extended, and the baffle is close to the end of the connecting groove. The purpose of setting the spring and the baffle is that when the connecting column and the connecting sleeve are installed, the spring will be squeezed by the entering connecting column, and will be compressed to different degrees as the depth of the connecting column enters, that is, different sizes of elastic energy storage will be generated. When it is necessary to replace the electric induction heating copper tubes of different specifications and models, the staff only needs to lift the card board, and preferably a handle can be set on the card board for easy operation. Then the connecting teeth on the card board are separated from the clamping teeth, and the elastic energy storage generated by the compression of the spring will be released instantly, so that the connecting column, the electric induction heating copper tube as a whole, and the connecting sleeve and the mounting seat as a whole can be quickly separated. The gear carburizing and quenching equipment further adopts connecting columns, connecting sleeves, clamping plates and clamping teeth as well as the cooperation of springs and baffles, which can conveniently replace and install electric induction heating copper tubes of different specifications and models to adapt to gears of different specifications and sizes to be processed, thereby avoiding heat loss and improving the efficiency of thermal resource utilization.
