Description

Technical Field

[0001] This utility model belongs to the field of electro-explosive spraying technology, and specifically relates to an electro-explosive spraying gun. Background Technology

[0002] Metal surface processing plays a crucial role in modern industrial production, widely used in machinery, petrochemicals, automobiles, aerospace, and many other fields. As a highly efficient surface treatment technology, electro-explosive spraying, a novel thermal spraying method, offers numerous advantages over other spraying technologies, such as strong environmental friendliness, high energy efficiency, minimal damage to the substrate material, and strong coating adhesion. Its working principle involves applying a pulsed high-current to the spraying material, causing it to rapidly absorb a large amount of energy and explode within a very short time. Under the impact force, the explosion products bond with the substrate material at high speed, ultimately forming a high-performance coating.

[0003] Current electric explosion equipment suffers from problems such as complex structure, difficult installation, limited nozzle shape that is difficult to replace, and inconvenient spray range adjustment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an electric explosion spray gun to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an electro-explosive spray gun, including a spray gun base. The spray gun base is provided with a spraying component, a constraint and guide component, an electro-explosive component and a connecting component. The constraint and guide component is provided with a carrier belt, and the surface of the carrier belt is provided with metal wires.

[0008] The connecting assembly is used to clamp the spray gun base, the spray assembly, and the constraint guide assembly to connect the spray gun base, the spray assembly, and the constraint guide assembly together. The carrier belt is used to move the metal wire inside the constraint guide assembly. The electro-explosion assembly is used to inject a pulsed high current into the moving metal wire so that the explosion products of the metal wire are ejected through the spray assembly.

[0009] Furthermore, a spraying assembly is provided on one side of the spray gun base, a constraint guide assembly is provided on the front side of the spray gun base, a carrier belt is provided inside the constraint guide assembly, an electro-explosive assembly is provided inside the spray gun base, and a connecting assembly is provided on the side of the spray gun base opposite to the constraint guide assembly.

[0010] Furthermore, the spraying assembly includes a spraying base, which is sleeved on one side of the spray gun base. A constraint groove is formed on the inner wall of the spraying base, and a spraying port is formed on the inner wall of the constraint groove.

[0011] Furthermore, the constraint guide assembly includes a baffle plate disposed on the front of the spray gun base and the spray base, and a placement groove is formed on the back of the baffle plate. The spray base is disposed inside the placement groove, and channels are formed on the upper and lower sides of the spray base and the baffle plate. The channels extend into the interior of the placement groove, and the carrier belt and the metal wire are movably connected to the channels.

[0012] Furthermore, the electro-explosive assembly includes electrode holes, two of which are symmetrically opened on the upper and lower sides of the spray gun base. A high-voltage conductive rod and a grounding conductive rod are respectively arranged inside the two electrode holes. An insulating sleeve is fitted on the outer surface of the high-voltage conductive rod and the grounding conductive rod. Mounting grooves are opened on the upper and lower sides of the two electrode holes. A high-voltage electrode plate is arranged inside the mounting groove on the upper side of the high-voltage conductive rod, and a grounding electrode plate is arranged inside the mounting groove on the lower side of the grounding conductive rod.

[0013] Furthermore, a high-pressure limiting hole is provided at the top of the spray gun base. The high-pressure limiting hole passes through the high-pressure electrode plate and extends into the interior of the high-pressure conductive rod. A high-pressure limiting bolt is threaded into the interior of the high-pressure limiting hole. A grounding limiting hole is provided at the bottom of the spray gun base. The grounding limiting hole passes through the grounding electrode plate and extends into the interior of the grounding conductive rod. A grounding limiting bolt is threaded into the interior of the grounding limiting hole.

[0014] Furthermore, the connecting assembly includes an insulating plate disposed on the front of the shielding plate. Clamping plates are provided on both the front of the insulating plate and the back of the spray gun base. Several connecting holes are opened on the front of the clamping plates. The connecting holes penetrate the two clamping plates, the shielding plate, the spray base, and the spray gun base. Connecting bolts are movably connected inside the connecting holes, and connecting nuts are threaded onto the outer surface of the connecting bolts.

[0015] This utility model has the following beneficial effects:

[0016] This invention connects the spray gun base, spraying assembly, and constraint guide assembly together via a connecting component, allowing the three components to be assembled and overlapped to form a modular electro-explosive spray gun. By setting the spray gun as a whole into multiple independent and replaceable modules, this structural design not only reduces the complexity and cost of the production process and greatly reduces the difficulty of installing the modular electro-explosive spray gun, but also makes the product more stable and reliable during use. At the same time, it makes maintenance and upgrades more convenient. When a module needs to be updated, the user only needs to replace that module instead of replacing the entire product, which greatly reduces the cost of use and time.

[0017] This invention features multiple spray bases, each with a different nozzle diameter and shape. This design allows for the replacement of the spray bases as needed when using the spray gun, thereby adjusting the range of particles ejected from the nozzles by the electro-explosion of the metal wire.

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is an electric explosion spray gun, including a spray gun base 1, on which a spraying component 2, a constraint guide component 3 and a connecting component 7 are provided. The connecting component 7 is used to clamp the spray gun base 1, the spraying component 2 and the constraint guide component 3.

[0031] The spraying assembly 2 includes a spraying base 201, which is sleeved on one side of the spray gun base 1. The inner wall of the spraying base 201 has a constraint groove 202, and the inner wall of the constraint groove 202 has a spray nozzle 203. The connecting assembly 7 is used to lock the spray gun base 1, the spraying base 201 and the constraint guide assembly 3 together, so that the three surround the constraint groove 202 to form an explosion cavity. When the spray gun base 1 and the constraint guide assembly 3 are kept in the locked state, the spraying base 201 can be replaced to adapt to the spray nozzle 203 of different ranges.

[0032] Furthermore, in further applications, the constraint groove 202 of the spray base 201 can be made with an asymmetrical trapezoidal cross section, allowing insertion into the spray gun base only in one direction, thus achieving the effect of positioning and installation. A red matching line is set at the edge of the contact surface between the spray base 201 and the spray gun base 1, and a blue matching line is set at the contact surface between the constraint guide component 3 and the spray base, further improving installation efficiency through visual design elements.

[0033] The spray gun base 1 has a spraying component 2 on one side, a constraint guide component 3 on the front side, a carrier belt 4 inside the constraint guide component 3, an electro-explosive component 6 inside the spray gun base 1, and a connecting component 7 on the side of the spray gun base 1 opposite to the constraint guide component 3.

[0034] The spray assembly 2 is placed on one side of the spray gun base 1, while the constraint guide assembly 3 is placed on the front of the spray assembly 2 and the spray gun base 1. Then, the three are clamped by the connecting assembly 7, so that the spray gun base 1, the spray assembly 2, and the constraint guide assembly 3 are assembled and overlapped to form a modular electro-explosive spray gun. During the spraying operation, the carrier belt 4 is moved into the interior of the constraint guide assembly 3 and pulled, so that the carrier belt 4 drives the metal wire 5 to move inside the constraint guide assembly 3. During this process, the electro-explosive assembly 6 can inject a pulsed high current into the interior of the metal wire 5. The particles generated by the electro-explosion of the metal wire 5 are constrained by the spray assembly 2 and ejected during the spraying process.

[0035] When it is necessary to adjust the spray range of the spray nozzle 203 or to replace the spray chamber, only the part of the connecting assembly 7 that connects the spray gun base 1, the spray base 201 and the constraint guide assembly 3 needs to be opened to replace the spray base 201 without having to completely disassemble it. This solves the problem of complex structure and difficult installation of traditional spray chambers. Since the spray nozzle 203 is set on the spray base 201, by replacing different spray bases 201, different nozzle sizes can be changed to achieve the purpose of changing the spray range.

[0036] The spray gun base 1, spray assembly 2, and constraint guide assembly 3 can be connected together by the connecting component 7, so that the three can be assembled and overlapped to form a modular electro-explosive spray gun. By setting the spray gun as a whole into multiple independent and replaceable modules, this structural design not only reduces the complexity and cost of the production process and greatly reduces the difficulty of installing the modular electro-explosive spray gun, but also makes the product more stable and reliable during use. At the same time, it makes maintenance and upgrades more convenient. When a module needs to be updated, the user only needs to replace the module instead of replacing the entire product, which greatly reduces the cost of use and time.

[0037] The particles generated by the electro-explosion of the metal wire 5 can flow to the spray nozzle 203 under the guidance of the constraint groove 202 and be ejected through the spray nozzle 203. The constraint groove 202 and the spray nozzle 203 can effectively constrain the spraying range of the metal particles, thereby making the coating distribution and thickness on the workpiece uniform. Quality is guaranteed while improving efficiency. When using the spray gun, multiple spray bases 201 can be equipped, and the diameter of the spray nozzle 203 set on each spray base 201 is different. This setting allows the spray base 201 to be replaced as needed when using the spray gun, thereby adjusting the range of the particles generated by the electro-explosion of the metal wire 5 as they are ejected from the inside of the spray nozzle 203.

[0038] The constraint guide assembly 3 is provided with a carrier belt 4, and the surface of the carrier belt 4 is provided with metal wires 5. The spray gun base 1 is also provided with an electro-explosion assembly 6. The carrier belt 4 is used to drive the metal wires 5 to move inside the constraint guide assembly 3. The electro-explosion assembly 6 is used to inject a pulsed high current into the moving metal wires 5 so that the explosion products of the metal wires 5 are ejected through the spray nozzle 203.

[0039] In one embodiment, the constraint guide component 3 includes a baffle plate 301, which is disposed on the front of the spray gun base 1 and the spray base 201. A placement groove 302 is provided on the back of the baffle plate 301, and the spray base 201 is disposed inside the placement groove 302. Channels 303 are provided on the upper and lower sides of the spray base 201 and the baffle plate 301, and the channels 303 extend into the interior of the placement groove 302. The carrier belt 4 and the metal wire 5 are movably connected to the channels 303.

[0040] After placing the shielding plate 301 on the front of the spray gun base 1, and then placing the spray base 201 inside the placement groove 302, the modular electro-explosive spray gun formed by the spray gun base 1, spray base 201, and shielding plate 301 is a cuboid of 123mm × 106mm × 39mm. Simultaneously, the shielding plate 301, spray gun base 1, and constraint groove 202 cooperate to form a converging cavity (i.e., the explosion cavity mentioned earlier). Under the guidance of the converging cavity, the particles generated after the metal wire 5 explodes can flow more effectively to the spray nozzle 203. When the shielding plate 301 and spray base 201 are in contact, a channel 303 is formed. The distance between the inner walls of this channel 303 is 2mm, allowing the carrier belt 4 to move the metal wire 5 through the channel 303 into the converging cavity. Furthermore, the inner wall shape of the channel 303 and the placement groove 302 is arc-shaped, which facilitates the placement of the metal wire 5.

[0041] A flexible carrier belt 4 has a metal wire 5 fixed to its surface. As the motor drives the carrier belt 4 downwards, the new metal wire 5 is fed into the explosive gun through channel 303. Both ends of the metal wire 5 contact the high-voltage / grounding electrode plates respectively. After the explosion, the motor immediately drives the carrier belt 4 to move downwards by one step, and the new metal wire segment automatically fills the gap in the electrode contact area. Waste wire is discharged to the recycling device through the lower channel 303. This design, through a mechatronics approach, achieves automated and continuous supply of metal wire during electro-explosive spraying, significantly improving operational efficiency and coating uniformity.

[0042] In one embodiment, the above-mentioned electro-explosive assembly 6 includes electrode holes 601. Two electrode holes 601 are symmetrically arranged on the upper and lower sides of the spray gun base 1. A high-voltage conductive rod 602 and a grounding conductive rod 603 are respectively disposed inside the two electrode holes 601. Insulating sleeves 604 are fitted onto the outer surfaces of the high-voltage conductive rod 602 and the grounding conductive rod 603. Two mounting grooves 605 are provided inside the spray gun base 1. The two mounting grooves 605 are located above the high-voltage conductive rod 602 and below the grounding conductive rod 603, respectively. A high-voltage conductive rod 602 is disposed inside the mounting groove 605 located above the high-voltage conductive rod 602. A high-pressure electrode plate 606 is provided, and a grounding electrode plate 607 is provided inside the mounting groove 605 located below the grounding conductive rod 603. A high-pressure limiting hole 608 is provided on the top of the spray gun base 1. The high-pressure limiting hole 608 passes through the high-pressure electrode plate 606 and extends into the interior of the high-pressure conductive rod 602. A high-pressure limiting bolt 609 is threadedly connected inside the high-pressure limiting hole 608. A grounding limiting hole 610 is provided on the bottom of the spray gun base 1. The grounding limiting hole 610 passes through the grounding electrode plate 607 and extends into the interior of the grounding conductive rod 603. A grounding limiting bolt 611 is threadedly connected inside the grounding limiting hole 610.

[0043] By placing the high-voltage electrode 606 and the grounding electrode 607 inside the corresponding mounting slot 605, and simultaneously moving the high-voltage conductive rod 602 and the grounding conductive rod 603 inside the corresponding electrode hole 601, then rotating the high-voltage limiting bolt 609 inside the high-voltage limiting hole 608 and rotating the grounding limiting bolt 611 inside the grounding limiting hole 610, the high-voltage electrode 606 is connected to the high-voltage conductive rod 602, and the grounding electrode 607 is connected to the grounding conductive rod 603. The mounting slot 605 is connected to the placement slot 302, so that both the high-voltage electrode plate 606 and the grounding electrode plate 607 are inside the placement slot 302. When the carrier belt 4 drives the metal wire 5 to move through the channel 303 inside the placement slot 302, both the high-voltage electrode plate 606 and the grounding electrode plate 607 can come into contact with the metal wire 5. At this time, the energy storage capacitor of the external electric explosion device discharges to the metal wire 5 through the high-voltage conductive rod 602, the high-voltage limiting bolt 609, the grounding conductive rod 603, the grounding limiting bolt 611, the high-voltage electrode plate 606, and the grounding electrode plate 607. The particles generated by the electric explosion of the metal wire 5 are constrained by the constraint slot 202 during the ejection process and are ejected from the ejection port 203.

[0044] In one embodiment, the connecting assembly 7 includes an insulating plate 701, which is disposed on the front side of the shielding plate 301. Clamping plates 702 are provided on both the front side of the insulating plate 701 and the back side of the spray gun base 1. Several connecting holes 703 are opened on the front side of the clamping plates 702. The connecting holes 703 pass through the two clamping plates 702, the shielding plate 301, the spray base 201 and the spray gun base 1. A connecting bolt 704 is movably connected inside the connecting hole 703. A connecting nut 705 is threadedly connected to the outer surface of the connecting bolt 704.

[0045] The clamping plate 702 is a cuboid with dimensions of 113mm × 96mm × 5mm, and the insulating plate 701 is a thin cuboid with dimensions of 113mm × 96mm × 2mm. After the spray gun base 1, the spray base 201, and the shielding plate 301 are spliced ​​and overlapped together, the insulating plate 701 is placed on the front of the shielding plate 301. Then, the two clamping plates 702 are placed on the back of the spray gun base 1 and the front of the insulating plate 701, respectively. Next, several connecting bolts 704 are moved into the corresponding connecting holes 703, and several connecting nuts 705 are rotated to the outer surface of the connecting bolts 704, so that the connecting nuts 705 cooperate with the connecting bolts 704 to connect the spray gun base 1, the spray base 201, the shielding plate 301, the insulating plate 701, and the two clamping plates 702 together.

[0046] Through the above technical solution, 1. The spray gun base 1, spray component 2, and constraint guide component 3 can be connected together by the connecting component 7, so that the three can be spliced ​​together to form a modular electro-explosive spray gun. By setting the spray gun as a whole into multiple independent and replaceable modules, this structural design not only reduces the complexity and cost of the production process and greatly reduces the difficulty of the electro-explosive spray gun installation process, but also makes the product more stable and reliable during use, and makes maintenance and upgrades more convenient. When a module needs to be updated, the user only needs to replace the module without replacing the entire product, which greatly reduces the cost of use and time; 2. By equipping multiple spray bases 201, and the diameter and shape of the spray nozzles 203 set on each spray base 201 are different, this setting allows the spray bases 201 to be replaced as needed when using the spray gun, so that the range of the particles generated by the electro-explosion of the metal wire 5 when they are sprayed out from the inside of the spray nozzles 203 can be adjusted.

[0047] In addition, in specific applications, a 1mm silicone rubber sealing layer is added between the insulating board 701 and the spray base 201. Specifically:

[0048] A 1mm silicone rubber film is installed between the two contact surfaces, forming a sandwich structure: injection base 201 → silicone rubber layer → insulating plate 701. This layout ensures that the sealing layer is in a critical sealing position on the sidewall of the explosion cavity.

[0049] Sealing Mechanism: The high elasticity of silicone rubber can fill microscopic gaps generated during modular assembly, such as the assembly tolerances between the spray base 201 and the baffle plate 301. Silicone rubber can withstand the high temperatures generated by the instantaneous electrical explosion (the explosion temperature of metal wires typically exceeds 2000℃), preventing seal failure. Under the impact of a pulse explosion, the viscoelastic properties of silicone rubber can absorb vibration energy, preventing metal particles from leaking out from the circumferential gap of the connecting bolt 704.

[0050] This forms a complementary sealing system with the existing constraint groove 202, strictly guiding the explosion products to the injection port 203. The silicone rubber layer is replaceable and compatible with the modular spray gun structure; it can be replaced simply by disassembling the connecting component 7 after wear. Safety enhancement: Eliminates equipment damage or operational risks caused by high-temperature particle side leakage.

[0051] This improvement, while maintaining the modular advantages of the original patent (quick-change spray base 201), solves the micro-leakage problem of traditional rigid connections by adding a flexible sealing layer, representing an innovative optimization of the sealing technology for electric explosion spray guns.
