Description

Technical Field

[0001] This utility model relates to the field of milling cutter heating technology, and more specifically, to an infrared heating device for tungsten carbide milling cutters. Background Technology

[0002] Tungsten carbide end mills have the characteristics of high hardness, high strength, good wear resistance, good thermal stability, good corrosion resistance, and low and uniform thermal conductivity. These characteristics make tungsten carbide end mills perform well in high-speed cutting and ultra-precision cutting operations, and they are suitable for cutting and precision machining of various cemented carbide materials.

[0003] However, the technical solution provided by this patent has the following problems:

[0004] Traditional fixed infrared heaters can cause some areas of tungsten carbide end mills to overheat while others are underheated. Uneven heating can alter the material properties of the tungsten carbide end mill, such as hardness and toughness. This alteration can affect the cutting performance and lifespan of the tool. Furthermore, due to uneven heating, fixed infrared heaters require higher energy output to achieve the desired heating effect, leading to reduced energy efficiency and increased costs.

[0005] This invention can accurately and uniformly heat tungsten carbide end mills, automatically adjust the spacing of the clamping blocks, and drive the end mill to rotate with the motor. In conjunction with the heater, it can achieve uniform heating, thereby improving processing efficiency and quality. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide an infrared heating device for tungsten carbide end mills.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an infrared heating device for tungsten steel end mills, comprising: a housing, two movable blocks slidably connected to the bottom of the housing, a clamping block fixedly installed on the inner side of the movable blocks, a cover plate hinged to the rear end of the housing, a heater fixedly installed on the cover plate, a sliding groove opened at the bottom of the housing, the sliding groove being slidably connected to the movable blocks, a rotating block being rotatably connected inside the movable blocks, and the clamping blocks being divided into an upper clamping block and a lower clamping block, the upper clamping block being fixedly installed on the rotating block, and the lower clamping block being threadedly connected to the upper clamping block.

[0008] A further preferred embodiment: a support leg is fixedly installed at the bottom of the box, heat dissipation holes are provided at both the left and right ends of the box, and a motor is fixedly installed at the bottom left end of the box.

[0009] A further preferred embodiment: a double-ended screw is fixedly installed at one output end of the motor, the double-ended screw is rotatably installed inside the slide groove, and the double-ended screw is threadedly connected to the moving block.

[0010] A further preferred embodiment: a slider is fixedly installed at the bottom of the movable block, the slider is slidably connected to the slide groove, and a screw hole is provided on the slider, the screw hole being threadedly connected to a double-ended screw.

[0011] A further preferred embodiment: a second motor is fixedly installed on the outer end of the moving block on one side inside the housing, and the output end of the second motor is fixedly connected to the rotating block.

[0012] A further preferred embodiment: each of the four corners of the upper clamping block and the lower clamping block is provided with a screw hole, and a bolt is internally threaded into each screw hole. The upper clamping block is threadedly connected to the lower clamping block by the bolt.

[0013] Beneficial effects:

[0014] 1. By incorporating heat dissipation holes, the heater continuously operates during the heating process, causing the internal temperature of the chamber to rise steadily. These holes effectively expel hot air from the chamber, preventing damage to internal electronic components, motors, and other structural parts due to excessive heat. This extends the equipment's lifespan and reduces maintenance costs. Furthermore, excessively high temperatures can interfere with the stability of infrared heating, leading to suboptimal heating results. The heat dissipation holes effectively maintain a suitable temperature environment within the chamber, ensuring stable heater operation and allowing the tungsten carbide end mill to be heated evenly according to predetermined parameters. This guarantees heating quality, thereby improving the overall efficiency and reliability of the device and ensuring its long-term normal operation.

[0015] 2. By incorporating a motor, a slide groove, a double-ended screw, and a moving block, the motor drives the double-ended screw to rotate. The double-ended screw and the moving block are connected by a threaded connection through a screw hole on the slide groove, and the moving block can slide within the slide groove. This design allows for automatic and precise adjustment of the distance between the two clamping blocks when dealing with tungsten carbide end mills of different lengths. Compared to manual adjustment, this not only avoids errors caused by human operation and improves the accuracy of clamping block distance adjustment, but also significantly increases adjustment efficiency and reduces preparation time. Furthermore, this automatic adjustment method is easy to operate, reducing the labor intensity of operators. The stable slide groove structure ensures smooth sliding of the moving block, making the entire adjustment process reliable and providing a good foundation for the subsequent heating of the tungsten carbide end mill, thus ensuring the efficient and stable operation of the device.

[0016] 3. By setting up a second motor and a rotating block, after the second motor is started, its output end drives the rotating block to rotate. Since the upper clamping block is fixedly installed on the rotating block, it drives the clamped tungsten carbide end mill to rotate together. This allows each part of the end mill to be fully exposed to the radiation of the infrared heater in sequence during the heating process, avoiding uneven heating in some areas and significantly improving the uniformity of heating. For end mills with complex shapes, the rotating block drives the end mill to rotate, which can ensure that the infrared rays can cover every part of the end mill, allowing the heat to penetrate evenly.

[0017] 4. In summary, this infrared heating device for tungsten carbide end mills, through the inclusion of a motor, a sliding groove, a double-ended screw, a moving block, and a clamping block, allows the motor to drive the double-ended screw to rotate, which in turn drives the moving block to slide within the sliding groove. This flexibly adapts to tungsten carbide end mills of different lengths, greatly improving work efficiency during the preparation stage and reducing manual operation errors and labor intensity. Simultaneously, the clamping block, composed of an upper and lower clamping block connected by bolts, securely holds the end mill, ensuring its stable position during heating. Combined with the second motor and the rotating block, it drives the end mill to rotate, allowing infrared rays to evenly radiate to all parts of the end mill, improving heating uniformity. Furthermore, the heat dissipation holes promptly expel the heat generated during heating, ensuring stable operation of the device. The coordinated work of these components provides a solid guarantee for the efficient and high-quality heating treatment of tungsten carbide end mills. Attached Figure Description

Detailed Implementation

[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0024] Please see Figure 1-4In this embodiment of the utility model, an infrared heating device for tungsten carbide end mills includes: a housing 1, with two movable blocks 2 slidably connected to the bottom of the housing 1, and clamping blocks 3 fixedly installed on the inner side of the movable blocks 2; a cover plate 102 is hinged to the rear end of the housing 1, and a heater 103 is fixedly installed on the cover plate 102; a sliding groove 106 is provided at the bottom of the housing 1, and the sliding groove 106 is slidably connected to the movable blocks 2; a rotating block 202 is rotatably connected inside the movable blocks 2; the clamping blocks 3 are divided into an upper clamping block 301 and a lower clamping block 302, the upper clamping block 301 is fixedly installed on the rotating block 202, and the lower clamping block 302 is threadedly connected to the upper clamping block 301; a support leg 101 is fixedly installed at the bottom of the housing 1; and heat dissipation holes 104 are provided at both the left and right ends of the housing 1; the bottom of the movable blocks 2 is fixedly... A slider 203 is fixedly installed, and the slider 203 is slidably connected to the slide groove 106. A motor 201 is fixedly installed on the outer end of the movable block 2 on one side of the box 1. The output end of the motor 201 is fixedly connected to the rotating block 202. The operator opens the cover plate 102, which is connected to the rear end of the box 1 by a hinge, to prepare for placing the tungsten carbide end mill. According to the size of the tungsten carbide end mill, the movable block 2 is slid along the slide groove 106 at the bottom of the box 1. Since the slider 203 fixedly installed at the bottom of the movable block 2 is adapted to the slide groove 106, the movable block 2 can slide smoothly. When the movable block 2 slides, it drives the clamping block 3 on its inner side to move, thereby adjusting the two clamping blocks 3 to a suitable distance to accommodate the length of the tungsten carbide end mill to be heated. The tungsten carbide end mill is then placed between the two clamping blocks 3. Then, by adjusting the threaded connection between the lower clamping block 302 and the upper clamping block 301, the upper clamping block 301 and the lower clamping block 302 are tightly clamped to ensure the stability of the tungsten carbide end mill during heating. After fixing the tungsten carbide end mill, the cover plate 102 is closed, making the box 1 a relatively enclosed space, which is conducive to the concentration and retention of heat and improves heating efficiency. The heater 103, which is fixedly installed on the cover plate 102, is turned on. The heater 103 begins to emit infrared rays to heat the tungsten carbide end mill inside the box 1. If it is necessary to make the tungsten carbide end mill more evenly heated, the motor 201, which is installed on the outer end of the moving block 2 on one side inside the box 1, can be started. The output end of the motor 201 drives the rotating block 202 to rotate. Since the upper clamping block 301 is fixedly installed on the rotating block 202, Therefore, the rotation of the rotating block 202 will drive the upper clamping block 301 and the clamped tungsten carbide end mill to rotate together, so that all parts of the end mill can fully receive infrared radiation, achieving a more uniform heating effect. During the heating process, the heater 103 will raise the internal temperature of the housing 1. The heat dissipation holes 104 opened at both ends of the housing 1 can play a role in heat dissipation, preventing the internal temperature of the housing 1 from being too high and damaging the equipment or affecting the heating effect, and ensuring the normal operation of the device. When the tungsten carbide end mill reaches the required heating temperature and time, the heater 103 is turned off (if the motor 201 is started, it is also turned off at the same time), the cover plate 102 is opened, the threaded connection between the lower clamping block 302 and the upper clamping block 301 is loosened, the heated tungsten carbide end mill is taken out, and the moving block 2 is slid to the initial position.To prepare for the next heating operation, if multiple tungsten carbide end mills need to be heated simultaneously, the number of rotating blocks 202 can be increased. Then, a driving wheel can be added to the output end of motor 201, and a corresponding driven wheel can be added to one side of motor 201. The driven wheel is fixedly connected to the rotating block 202, and the driving wheel and driven wheel are connected by a transmission belt. This allows motor 201 to drive the corresponding driven wheel to rotate through the driving wheel, causing the corresponding rotating block 202 to rotate synchronously, thus enabling multiple end mills to be heated simultaneously.

[0025] In this embodiment of the utility model, a motor 105 is fixedly installed at the bottom left end of the housing 1. A double-ended screw 107 is fixedly installed at the output end of the motor 105. The double-ended screw 107 is rotatably installed inside the slide groove 106 and is threadedly connected to the moving block 2. A screw hole 204 is provided on the slider 203, and the screw hole 204 is threadedly connected to the double-ended screw 107. Based on the length of the tungsten steel end mill to be heated, the motor 105 installed at the bottom left end of the housing 1 is started. After 105 is turned on, its output end drives the double-ended screw 107 to rotate. Since the double-ended screw 107 is rotatably installed inside the slide groove 106 and is threadedly connected to the moving block 2 through the screw hole 204 opened on the slider 203, as the double-ended screw 107 rotates, the two moving blocks 2 will move towards or away from each other along the slide groove 106, thereby automatically adjusting the clamping block 3 to a suitable distance to adapt to tungsten carbide end mills of different lengths. Compared with manually sliding the moving block 2, this method is more precise and efficient.

[0026] In this embodiment of the utility model, screw holes 303 are provided at the four corners of the upper clamping block 301 and the lower clamping block 302. Bolts 304 are threaded into the screw holes 303. The upper clamping block 301 is threadedly connected to the lower clamping block 302 through the bolts 304. The tungsten carbide end mill is placed between the two clamping blocks 3. The clamping block 3 is composed of the upper clamping block 301 and the lower clamping block 302. The upper clamping block 301 is fixedly installed on the rotating block 202. The lower clamping block 302 is threadedly connected to the upper clamping block 301. The operator rotates the lower clamping block 302 and uses the threaded engagement to make the upper and lower clamping blocks tightly clamp the tungsten carbide end mill, ensuring that the end mill is stable and does not move during the subsequent heating process.

[0027] Working principle: The operator opens the cover plate 102 at the rear of the housing 1, which is connected by a hinge, to provide operating space for placing the tungsten carbide end mill. Based on the length of the tungsten carbide end mill to be heated, the operator starts the motor 105 at the bottom left of the housing 1. After the motor 105 starts running, its output drives the double-ended screw 107 to rotate. Since the double-ended screw 107 is rotatably installed in the slide groove 106 and is threadedly connected to the moving block 2 through the screw hole 204 on the slider 203, as the double-ended screw 107 rotates, the two moving blocks 2 will move in opposite directions along the slide groove 106, automatically adjusting the clamping blocks 3 to the appropriate spacing for the end mill length. This method is more precise and efficient than manually sliding the moving blocks 2. The tungsten carbide end mill is placed between the two clamping blocks 3, which are connected by the upper clamping block 301 and the lower clamping block 3. The unit consists of block 302. The upper clamping block 301 is fixedly mounted on the rotating block 202. The lower clamping block 302 is connected to the upper clamping block 301 via screw holes 303 at the four corners and bolts 304. The operator tightens the bolts 304, utilizing the threaded connection to ensure the upper and lower clamping blocks tightly clamp the tungsten carbide end mill, guaranteeing the end mill remains stable during subsequent heating. After securing the tungsten carbide end mill, the cover plate 102 is closed, creating a relatively enclosed space within the housing 1. This facilitates heat concentration and retention, improving heating efficiency. The heater 103, fixed to the cover plate 102, is then activated. The heater 103 emits infrared rays to heat the tungsten carbide end mill inside the housing 1. Subsequently, the motor 201, installed on the outer end of the moving block 2 on one side inside the housing 1, is started. The output end of motor 201 drives the rotating block 202 to rotate. Since the upper clamping block 301 is fixedly installed on the rotating block 202, the rotation of the rotating block 202 will drive the upper clamping block 301 and the clamped tungsten carbide end mill to rotate together, so that all parts of the end mill can fully receive infrared radiation and achieve a more uniform heating effect. If multiple tungsten carbide end mills need to be heated at the same time, the number of rotating blocks 202 can be increased. A driving wheel can be added to the output end of motor 201, and a corresponding driven wheel can be added to one side of motor 201. The driven wheel is fixedly connected to the rotating block 202, and the driving wheel and the driven wheel are connected by a transmission belt. When motor 201 is running, it can drive the corresponding driven wheel to rotate through the driving wheel, so that the corresponding rotating block 202 rotates synchronously, realizing the simultaneous heating of multiple tungsten carbide end mills. The tungsten carbide end mills are heated simultaneously. During the heating process, the heater 103 will raise the internal temperature of the housing 1. The heat dissipation holes 104 at both ends of the housing 1 will dissipate heat to prevent the internal temperature of the housing 1 from being too high and damaging the equipment or affecting the heating effect, thus ensuring the normal operation of the device. When the tungsten carbide end mills reach the required heating temperature and time, the heater 103 is turned off (if the motor 201 is started, it is also turned off at the same time). The cover plate 102 is opened, the bolt 304 is rotated in the opposite direction, the threaded connection between the lower clamping block 302 and the upper clamping block 301 is loosened, the heated tungsten carbide end mills are taken out, and the motor 105 is started again. The motor 105 drives the double-headed screw 107 to rotate in the opposite direction, so that the two moving blocks 2 slide back to the initial position along the slide groove 106, preparing for the next heating operation.
