Description

Technical Field

[0001] This utility model relates to the field of thermal deburring technology, and in particular to a thermal deburring device with stable quality. Background Technology

[0002] With the continuous development of industrial production and the increasing demands for product quality, there is an urgent need for a high-efficiency, reliable method and device that can adapt to the deburring needs of various complex workpieces. Thermal explosion deburring technology has emerged to meet this need. Its basic principle is to place the workpiece in a sealed chamber, fill it with a certain proportion of combustible gas and oxygen, and then use an ignition device to make the mixed gas burn and explode instantly, generating a high-temperature, high-pressure, and high-speed shock wave that burns away the burrs in a very short time. This method has the advantages of high deburring efficiency, good effect, and the ability to remove burrs in complex locations, while having almost no impact on the surface finish, shape, size, and material properties of the workpiece.

[0003] To address the aforementioned issues, existing patents offer solutions. However, existing thermal deburring devices lack a structure to buffer the working chamber during an explosion. Consequently, during the thermal deburring process, the high-temperature and high-pressure shock wave generated by the explosion directly acts on the inner wall of the working chamber, subjecting it to enormous pressure. Prolonged exposure to such pressure may reduce the sealing performance of the working chamber, leading to flammable gas leakage and increasing safety hazards. It also shortens the service life of the working chamber.

[0004] Therefore, a thermal deburring device with stable quality is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a stable thermal deburring device that can solve the problem of existing thermal deburring devices that buffer the working chamber during the explosion. This results in the high-temperature and high-pressure shock wave generated by the explosion directly acting on the inner wall of the working chamber during the thermal deburring process, causing the working chamber to be subjected to enormous pressure. Long-term exposure to such pressure impact may reduce the sealing performance of the working chamber, leading to the leakage of flammable gas, thereby increasing safety hazards and shortening the service life of the working chamber.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-quality, stable hot-explosive deburring device, comprising a protective shell, a buffer mechanism fixedly connected to the inner side of the protective shell, a working chamber fixedly connected to the surface of the buffer mechanism, an air intake mechanism fixedly connected to the rear side of the working chamber, a sealing door rotatably connected to the front side of the protective shell, a placement plate slidably connected to the inner side of the working chamber, and an ignition device fixedly connected to the right side of the working chamber, the ignition end of the ignition device penetrating the buffer mechanism and extending to the inner side of the working chamber;

[0007] The buffer mechanism includes a rubber pad, several sleeves, a buffer spring, a connecting piece, a contact rod, and a buffer plate. The rubber pad is fixedly connected to the inner wall of the protective shell, the sleeves are fixedly connected to the surface of the rubber pad, the buffer springs are fixedly connected to the inner side of the sleeves, and the connecting piece is fixedly connected to the side of the buffer springs away from the sleeves.

[0008] Preferably, the contact rod is fixedly connected to the side of the connecting piece away from the buffer spring, the side of the contact rod away from the connecting piece passes through the working cavity and extends to the inside of the working cavity, and the buffer plate is fixedly connected to the side of the contact rod away from the buffer spring.

[0009] Preferably, the air intake mechanism includes two air intake pipes, two solenoid valves, a connecting pipe, and a PLC controller, with the air intake pipes fixedly connected to both sides of the rear side of the working chamber.

[0010] Preferably, the rear side of the intake pipe passes through the working chamber and the protective shell respectively and extends to the outside of the protective shell, and the solenoid valve is fixedly connected to the rear side of the intake pipe.

[0011] Preferably, the connecting pipe is fixedly connected to the rear side of the solenoid valve, the inner side of the connecting pipe is provided with an internal thread, and the PLC controller is fixedly connected to the surface of the rear side of the protective housing.

[0012] Preferably, a connecting block is fixedly connected to the right side of the inner wall of the protective shell, and a threaded hole is provided on the inner side of the connecting block.

[0013] Preferably, a threaded rod is rotatably connected to the right side of the sealing door, the rear side of the threaded rod is threaded into the inner side of the threaded hole, and a handle is fixedly connected to the front side of the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The buffer mechanism of this application is configured with rubber pads, sleeves, buffer springs, connecting plates, contact rods, and buffer plates. When an explosion occurs in the working chamber and a shock wave is generated, the buffer plate can directly withstand the impact force of the shock wave. After being subjected to force, the buffer plate squeezes the connecting plate through the contact rod, which in turn compresses the buffer spring. The buffer spring absorbs the energy of the shock wave during the compression process, playing a buffering role, reducing the direct impact of the shock wave on the working chamber, preventing the working chamber from being deformed or damaged due to excessive impact force, and improving the stability and service life of the working chamber. The rubber pad can further absorb some of the impact force and increase the buffering effect between the protective shell and the buffer mechanism. At the same time, it plays a certain role in sealing and sound insulation, reducing noise and preventing the leakage of flammable gas, thereby improving the safety and reliability of the device.

[0017] 2. The air intake mechanism of this application is equipped with two air intake pipes, which can be used to transport different gases, such as combustible gas and combustion-supporting gas, respectively. This facilitates the accurate delivery of gas into the working chamber according to a predetermined ratio. The solenoid valve can control the gas flow and accurately open or close according to the instructions of the PLC controller, ensuring precise control of the gas delivery volume and delivery time. This ensures the accurate ratio of combustible gas and combustion-supporting gas during the thermal deburring process, making the explosion process stable and reliable, and improving the quality and effect of deburring.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 The present invention provides the following technical solution:

[0028] A high-quality, stable thermal deburring device includes a protective shell 1, a buffer mechanism 2 fixedly connected to the inner side of the protective shell 1, a working chamber 3 fixedly connected to the surface of the buffer mechanism 2, an air intake mechanism 4 fixedly connected to the rear side of the working chamber 3, a sealing door 5 rotatably connected to the front side of the protective shell 1, a placement plate 10 slidably connected to the inner side of the working chamber 3, and an ignition device 14 fixedly connected to the right side of the working chamber 3. The ignition end of the ignition device 14 passes through the buffer mechanism 2 and extends to the inner side of the working chamber 3.

[0029] The buffer mechanism 2 includes a rubber pad 21, several sleeves 22, a buffer spring 23, a connecting piece 24, a contact rod 25, and a buffer plate 26. The rubber pad 21 is fixedly connected to the inner wall of the protective shell 1, the sleeves 22 are fixedly connected to the surface of the rubber pad 21, the buffer spring 23 is fixedly connected to the inner side of the sleeve 22, and the connecting piece 24 is fixedly connected to the side of the buffer spring 23 away from the sleeve 22.

[0030] In this embodiment: the protective outer shell 1 supports and limits the buffer mechanism 2, working chamber 3, air intake mechanism 4, and sealing door 5. The working chamber 3 is the core working area of ​​thermal deburring, providing a relatively enclosed space for deburring the workpiece, allowing the combustible gas to fully contact the workpiece, and ensuring that the energy generated by the explosion can be concentrated on the workpiece surface to achieve efficient deburring. The sealing door 5 is used to open and close the working chamber 3, facilitating the insertion and removal of the workpiece. At the same time, during the thermal deburring process, the sealing door 5 ensures the sealing of the working chamber 3. To prevent flammable gas leakage and explosion energy leakage, and to ensure the safe operation of the device, the placement tray 10 is used to place the workpiece to be deburred. After sliding to the inside of the working chamber 3, it can seal the working chamber 3 to prevent gas leakage. The ignition device 14 can ignite the flammable gas mixture in the working chamber 3, triggering the thermal explosion deburring process. The rubber pad 21 can absorb part of the impact force generated by the explosion, playing a buffering and shock-absorbing role, reducing the direct impact of the shock wave on the protective shell 1, and protecting the structural integrity of the protective shell 1. The sleeve 22 provides support for the buffer spring 23. The installation provides support and guidance, ensuring the stability of the buffer spring 23 during compression and extension, preventing spring twisting or displacement. When an explosion generates a shock wave, the buffer spring 23 is compressed, absorbing the shock wave's energy and converting kinetic energy into elastic potential energy. This reduces the impact of the shock wave on the working chamber 3, protecting its structure and extending its service life. The connecting piece 24 connects the buffer spring 23 and the contact rod 25, transmitting the impact force from the buffer spring 23 to the contact rod 25, and then further transmitting the force through the contact rod 25. The shock wave is passed to the buffer plate 26 to buffer and absorb it. The contact rod 25 connects the connecting piece 24 and the buffer plate 26, and transmits the buffering force of the buffer spring 23 to the working chamber 3, so that the buffer plate 26 can directly bear the impact force of the shock wave, thus effectively protecting the working chamber 3. The buffer plate 26 is in direct contact with the shock wave generated by the explosion, bears the impact force, and transmits the force to the buffer spring 23 and other components through the contact rod 25 to disperse and absorb the energy of the shock wave, reduce the direct effect of the shock wave on the inner wall of the working chamber 3, and prevent the working chamber 3 from being damaged due to excessive force.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the contact rod 25 is fixedly connected to the side of the connecting piece 24 away from the buffer spring 23. The side of the contact rod 25 away from the connecting piece 24 passes through the working cavity 3 and extends to the inside of the working cavity 3. The buffer plate 26 is fixedly connected to the side of the contact rod 25 away from the buffer spring 23.

[0032] Specifically, such as Figure 6 As shown, the air intake mechanism 4 includes two air intake pipes 41, two solenoid valves 42, a connecting pipe 43, and a PLC controller 44. The air intake pipes 41 are fixedly connected to both sides of the rear side of the working chamber 3.

[0033] Specifically, such as Figure 6 As shown, the rear side of the intake pipe 41 passes through the working chamber 3 and the protective shell 1 respectively and extends to the outside of the protective shell 1. The solenoid valve 42 is fixedly connected to the rear side of the intake pipe 41.

[0034] In this embodiment: by setting an air inlet pipe 41 to transport combustible gas and combustion-supporting gas, gas can be accurately delivered into the working chamber 3 according to a predetermined ratio, providing the necessary gas conditions for the thermal deburring process. The solenoid valve 42 can precisely control the gas flow and opening and closing according to the instructions of the PLC controller 44, realizing the control of gas flow and delivery time. The connecting pipe 43 facilitates quick and convenient connection and disconnection with external gas supply equipment, facilitating gas supply and equipment maintenance. The PLC controller 44 automates the entire air intake process, precisely controlling the action of the solenoid valve 42 through a preset program, realizing the intelligent and precise air intake process, and reducing human error.

[0035] Specifically, such as Figure 6 As shown, the connecting pipe 43 is fixedly connected to the rear side of the solenoid valve 42, and the inner side of the connecting pipe 43 is provided with an internal thread. The PLC controller 44 is fixedly connected to the surface of the rear side of the protective housing 1.

[0036] Specifically, such as Figure 2 As shown, a connecting block 6 is fixedly connected to the right side of the inner wall of the protective shell 1, and a threaded hole 7 is provided on the inner side of the connecting block 6.

[0037] In this embodiment: by setting the connecting block 6, the threaded hole 7 can be supported and limited. By setting the threaded hole 7 and cooperating with the threaded rod 8, the sealing door 5 can be fixed and opened by means of threaded connection.

[0038] Specifically, such as Figure 7 As shown, a threaded rod 8 is rotatably connected to the right side of the sealing door 5. The rear side of the threaded rod 8 is threadedly connected to the inner side of the threaded hole 7, and a handle 9 is fixedly connected to the front side of the threaded rod 8.

[0039] Specifically, such as Figure 4 , Figure 2 As shown, slide rails 11 are fixedly connected to both sides of the inner side of the working chamber 3, and the placement plate 10 is slidably connected to the top of the slide rails 11. A stop block 12 is fixedly connected to the front side of the placement plate 10, and a handle 13 is fixedly connected to the front side of the stop block 12.

[0040] In this embodiment: By setting a threaded rod 8, which is threadedly connected to the threaded hole 7 on the connecting block 6, when it is necessary to close the sealing door 5, the threaded rod 8 is rotated to screw it into the threaded hole 7, which can firmly fix the sealing door 5 to the protective shell 1, ensuring the sealing of the working chamber 3 and preventing the leakage of combustible gas and explosion energy. When it is necessary to open the sealing door 5, the threaded rod 8 is rotated in the opposite direction to easily unscrew it from the threaded hole 7. The operation is convenient and quick. By setting a handle 9, the operator can rotate the threaded rod 8 more easily, reducing the labor intensity of the operator and improving work efficiency. By setting a slide rail 11, a sliding track is provided for the placement tray 10. By setting a stop block 12, the front side of the working chamber 3 can be sealed after the placement tray 10 slides into the working chamber 3 to prevent gas leakage. By setting a handle 13, it is convenient for the operator to operate the placement tray 10.

[0041] Working principle: First, the operator moves the protective housing 1 to the predetermined working position. Then, by rotating the handle 9, the threaded rod 8 gradually separates from the threaded hole 7, at which point the sealing door 5 is unlocked, and the operator can open it. Next, the operator holds the handle 13 and pulls the stop block 12 outward. As the stop block 12 moves outward, it drives the placement tray 10 to slide forward along the slide rail 11. After the placement tray 10 slides to the appropriate position, the operator places the workpiece to be deburred inside the placement tray 10. After the workpiece is placed, the operator holds the handle 13 again and pushes the stop block 12 towards the inside of the protective housing 1. The stop block 12 then drives the placement tray 10 along the slide rail 11. The slide rail 11 returns to the working chamber 3. After the placement plate 10 returns to its original position, the stop block 12 fits tightly against the inner side of the protective shell 1, forming a seal to prevent gas leakage from the working chamber 3. Next, the operator closes the sealing door 5 with the protective shell 1 and turns the handle 9 again to make the threaded rod 8 tightly threaded with the threaded hole 7, thus ensuring that the sealing door 5 and the protective shell 1 are firmly closed. Subsequently, the operator connects the external air intake device to the two air intake pipes 41. After the connection is completed, the required air intake parameters are precisely set through the PLC controller 44, and a command is issued to control the solenoid valve 42 to start. At this time, the external air intake device, according to the set parameters, introduces combustible gas and combustion-supporting gas through the two air intakes. Pipe 41 stably discharges gas into the working chamber 3. When the amount of combustible gas and oxidizing gas discharged reaches the preset standard, the PLC controller 44 promptly controls the solenoid valve 42 to close. At the same time, the operator shuts off the external air intake equipment to ensure that the gas volume in the working chamber 3 is accurate and stable. Once the preparation is complete, the operator activates the ignition device 14. The ignition device 14 quickly ignites and detonates the combustible gas in the working chamber 3. At the moment of ignition, the high temperature and high pressure energy generated can efficiently burn off the burrs on the surface of the workpiece. At the same time, the shock wave generated by the explosion directly impacts the buffer plate 26. After being impacted, the buffer plate 26 will shift to both sides of the working chamber 3. The movement of the buffer plate 26 drives the contact rod 2. 5. Simultaneous movement causes the contact rod 25 to push the connecting piece 24 to compress the buffer spring 23. The buffer spring 23 utilizes its elastic properties to absorb and buffer the impact force generated by the explosion, transferring the buffered impact force to the rubber pad 21. The rubber pad 21, with its excellent buffering and energy absorption properties, further absorbs the impact force, effectively protecting the structural safety of the working chamber 3 and the entire device. Finally, after the hot explosion deburring operation is completed, the operator turns the handle 9 again to separate the threaded rod 8 from the threaded hole 7, opens the sealing door 5, and then pulls out the placement tray 10 through the handle 13 to remove the workpiece that has been deburred from the inside of the placement tray 10. This completes the entire hot explosion deburring operation process.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
