Description

Technical Field

[0001] This utility model relates to the field of metal tool manufacturing technology, specifically to a sandblasting device for metal tool manufacturing. Background Technology

[0002] With the rapid development of my country's economy and the progress of its manufacturing industry, metal sandblasting technology has been widely used in many fields, such as machinery manufacturing, aerospace, automobile manufacturing, shipbuilding, and building decoration. In the process of metal tool manufacturing, sandblasting equipment is needed to treat the tool surface to change its mechanical properties and improve its fatigue resistance. Metal sandblasting technology is constantly developing. Its principle is to use high-speed jet abrasive to impact, cut, and rub the metal surface to achieve cleaning, deburring, and improvement of surface roughness. The process includes surface pretreatment and sandblasting steps. To promote the development of the industry, research on the sandblasting equipment market is of great significance, including promoting technological progress, guiding corporate decision-making, promoting industrial development, expanding application areas, and enhancing international competitiveness.

[0003] Chinese Patent Publication No. CN220260677U discloses a sandblasting device for metal tool manufacturing, including a fixed platform. A protective box is fixedly connected to the top of the fixed platform. A threaded rod is movably connected to the upper end of the inner cavity of the protective box via a bearing. A threaded sleeve is threadedly connected to the surface of the threaded rod. A support plate is fixedly connected to the bottom of the threaded sleeve. An electric push rod is fixedly connected to the bottom of the support plate. A storage box is fixedly connected to the bottom of the electric push rod. A flexible hose is connected to the top of the storage box, and the end of the flexible hose away from the storage box extends to the outside of the protective box. This invention, by setting up a threaded rod, threaded sleeve, support plate, electric push rod, driving gear, driven gear, and transmission rod, achieves the effect of conveniently adjusting the sandblasting position of the nozzle body, effectively improving the flexibility of sandblasting. By supporting the nozzle body through the support plate and electric push rod, the workload of workers is effectively reduced, thereby effectively improving sandblasting efficiency.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: When the above-mentioned device is used, it can only move laterally, which will result in the sandblasting process leaving four corners, thus leading to poor cleaning, deburring and surface roughness improvement effects. Therefore, there is an urgent need for a sandblasting device for metal tool manufacturing. Utility Model Content

[0005] The purpose of this invention is to provide a sandblasting device for metal tool manufacturing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sandblasting device for manufacturing metal tools, including a protective mechanism, wherein a sandblasting mechanism is provided on the top of the protective mechanism;

[0007] The sandblasting mechanism includes a dustproof housing, a motor fixedly connected to the top of the dustproof housing, a rotating rod fixedly connected to the output end of the motor, a first synchronous pulley fixedly connected to the surface of the rotating rod, a rotating seat rotatably connected to the end of the rotating rod away from the motor, a synchronous belt drivingly connected to the surface of the first synchronous pulley, a second synchronous pulley drivingly connected to the inner side of the synchronous belt, a flexible hose fixedly connected to the inner wall of the second synchronous pulley, a rotating tube fixedly connected to the inner wall of the second synchronous pulley, a sandblasting assembly provided at the end of the rotating tube away from the second synchronous pulley, and a nozzle provided on the surface of the sandblasting assembly.

[0008] The motor drives the first synchronous pulley, which in turn drives the synchronous belt to rotate. The synchronous belt then drives the second synchronous pulley to rotate, which in turn drives the rotating tube fixedly connected to its inner wall to rotate. The rotating tube then drives the sandblasting assembly to rotate inside the device housing, thereby sandblasting the metal tools.

[0009] Preferably, the protective mechanism includes a device housing, a placement plate is fixedly connected to the inner wall of the device housing, a discharge port is opened on the surface of the placement plate, a funnel is provided at the bottom of the inner wall of the device housing, a slide rail is fixedly connected to the bottom of the device housing, a sand collection box is provided on the surface of the slide rail, and a slider is fixedly connected to the inner wall of the sand collection box.

[0010] The device housing has a placement plate with a discharge port. The sprayed sand falls through the discharge port into a funnel at the bottom of the placement plate, and then into a sand collection box at the bottom. The slider of the sand collection box is slidably connected to the slide rail of the device housing, so the sand collection box can be removed and the sand inside can be reused.

[0011] Preferably, the top of the device housing is fixedly connected to the dustproof housing, and the rotating tube passes through the device housing and is rotatably connected to the device housing.

[0012] Preferably, three nozzles are provided, and the three nozzles are arranged linearly along the surface of the sandblasting assembly.

[0013] Preferably, the surface of the slider is slidably connected to the slide rail.

[0014] The sand collection box can be removed by sliding it.

[0015] Preferably, the bottom end of the rotating seat is fixedly connected to the inner wall of the dustproof shell, and the bottom end of the hose is fixedly connected to the rotating tube.

[0016] Preferably, a support frame is fixedly connected to the bottom of the device housing, and a device cover is hinged to the front of the device housing.

[0017] The support frame provides support for the outer casing of the device, and the device cover prevents sand from spilling out.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] Firstly, in this utility model, when using the sandblasting device, the motor plays a core role in providing power. When the motor starts, its output shaft begins to rotate and transmits power to the first synchronous pulley. The first synchronous pulley then begins to rotate, and the teeth or grooves on its rim mesh with the inner teeth of the synchronous belt, thereby driving the synchronous belt to rotate in a cycle. The synchronous belt fits tightly between the first and second synchronous pulleys, ensuring smooth power transmission. When the synchronous belt is driven to rotate by the first synchronous pulley, it drives the second synchronous pulley to rotate at the same speed or at a speed reduced by a certain ratio. The rotation of the second synchronous pulley is directly related to the rotation of the rotating tube. The inner wall of the rotating tube is tightly connected to the second synchronous pulley; therefore, when the second synchronous pulley rotates, the rotating tube also... The rotating tube rotates, which in turn drives the sandblasting assembly to rotate. The sandblasting assembly typically includes nozzles, abrasive delivery systems, and other components. It is used to propel abrasive at high speed onto the surface of metal tools to achieve cleaning, deburring, and increased surface roughness. Driven by the rotating tube, the sandblasting assembly can rotate within the housing of the device, thus achieving all-around sandblasting treatment of the metal tool surface. This sandblasting device uses a motor to drive a synchronous pulley and synchronous belt, achieving smooth and efficient driving of the rotating tube and sandblasting assembly, thereby completing the sandblasting treatment of the metal tool. This design not only improves sandblasting efficiency but also reduces noise and maintenance costs, providing a reliable technical means for the surface treatment of metal tools.

[0020] Secondly, the device of this utility model features a carefully designed placement plate inside its casing, with discharge ports on its surface. This allows excess sand to flow smoothly through these ports after sandblasting and fall into a specially designed funnel at the bottom of the placement plate. The shape and angle of the funnel are precisely calculated to ensure that the sand flows smoothly and centrally into the sand collection box below. As a key component for collecting and processing sand, the sand collection box is equipped with sliders on both sides for easy cleaning and replacement. These sliders perfectly match the pre-set slide rails inside the device casing, forming a stable and flexible sliding connection. When the user needs to clean the sand collection box or reuse the sand, they only need to gently push or pull the sand collection box, and it will slide smoothly out of the device casing along the slide rails. This greatly simplifies the operation process, improves work efficiency, and allows users to manage and recycle sand more easily. It achieves efficient sandblasting of metal tools, maximizes the utilization of sand, reduces resource waste, and embodies the concept of green and environmentally friendly manufacturing. At the same time, this design also improves the flexibility and practicality of the device, enabling it to better adapt to the diverse needs of different users. Attached Figure Description

[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] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please see Figures 1-4 A sandblasting device for metal tool manufacturing includes a protective mechanism 2, with a sandblasting mechanism 1 disposed on top of the protective mechanism 2.

[0030] The sandblasting mechanism 1 includes a dustproof housing 101. A motor 102 is fixedly connected to the top of the dustproof housing 101. A rotating rod 111 is fixedly connected to the output end of the motor 102. A first synchronous pulley 103 is fixedly connected to the surface of the rotating rod 111. A rotating seat 104 is rotatably connected to the end of the rotating rod 111 away from the motor 102. A synchronous belt 105 is driven to the surface of the first synchronous pulley 103. A second synchronous pulley 106 is driven to the inner side of the synchronous belt 105. A flexible hose 107 is fixedly connected to the inner wall of the second synchronous pulley 106. A rotating tube 108 is also fixedly connected to the inner wall of the second synchronous pulley 106. A sandblasting assembly 109 is provided at the end of the rotating tube 108 away from the second synchronous pulley 106. A nozzle 110 is provided on the surface of the sandblasting assembly 109.

[0031] Through the above technical solution, when using the sandblasting device, the motor 102 plays a core role in providing power. When the motor 102 starts, its output shaft begins to rotate and transmits power to the first synchronous pulley 103. The first synchronous pulley 103 then begins to rotate, and the teeth or grooves on its rim mesh with the inner teeth of the synchronous belt 105, thereby driving the synchronous belt 105 to rotate cyclically. The synchronous belt 105 is tightly fitted between the first synchronous pulley 103 and the second synchronous pulley 106, ensuring smooth power transmission. When the synchronous belt 105 is driven to rotate by the first synchronous pulley 103, it drives the second synchronous pulley 106 to rotate at the same speed or at a speed reduced by a certain ratio. The rotation of the second synchronous pulley 106 is directly related to the rotation of the rotating tube 108. The inner wall of the rotating tube 108 is tightly connected to the second synchronous pulley 106. Therefore, when the second synchronous pulley 106 rotates, the rotation... The rotating tube 108 also rotates, and the rotation of the rotating tube 108 ultimately drives the rotation of the sandblasting assembly 109. The sandblasting assembly 109 typically includes a nozzle, a sand conveying system, etc., and is used to spray sand at high speed onto the surface of the metal tool to achieve cleaning, deburring, and increasing surface roughness. Driven by the rotating tube 108, the sandblasting assembly 109 can rotate within the device housing 201, thereby achieving all-round sandblasting treatment of the metal tool surface. The sandblasting device drives the synchronous pulley 103, synchronous pulley 106, and synchronous belt 105 through the motor 102, achieving smooth and efficient driving of the rotating tube 108 and the sandblasting assembly 109, thus completing the sandblasting treatment of the metal tool. This design not only improves sandblasting efficiency but also reduces noise and maintenance costs, providing a reliable technical means for the surface treatment of metal tools.

[0032] Example 2

[0033] Please see Figures 1-4 Furthermore, based on Embodiment 1, the protective mechanism 2 includes a device housing 201, a placement plate 202 fixedly connected to the inner wall of the device housing 201, a discharge port 203 opened on the surface of the placement plate 202, a funnel 204 provided at the bottom of the inner wall of the device housing 201, a slide rail 205 fixedly connected to the bottom of the device housing 201, a sand collection box 206 provided on the surface of the slide rail 205, and a slider 207 fixedly connected to the inner wall of the sand collection box 206.

[0034] The top of the device housing 201 is fixedly connected to the dustproof housing 101, and the rotating tube 108 passes through the device housing 201 and is rotatably connected to the device housing 201.

[0035] There are three nozzles 110, which are arranged linearly along the surface of the sandblasting assembly 109.

[0036] The surface of slider 207 is slidably connected to slide rail 205.

[0037] The bottom end of the rotating seat 104 is fixedly connected to the inner wall of the dustproof housing 101, and the bottom end of the hose 107 is fixedly connected to the rotating tube 108.

[0038] A support frame 208 is fixedly connected to the bottom of the device housing 201, and a device cover 209 is hinged to the front of the device housing 201.

[0039] Through the above technical solution, a placement plate 202 is carefully set inside the device housing 201, with a discharge port 203 on its surface. This allows excess sand to pass smoothly through these discharge ports 203 after the sandblasting operation and fall into a specially configured funnel 204 at the bottom of the placement plate 202. The shape and angle of the funnel 204 are precisely calculated to ensure that the sand flows smoothly and centrally into the sand collection box 206 below it. As a key component for collecting and processing sand, the sand collection box 206 has sliders 207 installed on both sides to facilitate user cleaning and sand replacement. These sliders 207 are designed to interact with pre-set... The slide rail 205 fits perfectly, forming a stable and flexible sliding connection. When the user needs to clean the sand collection box 206 or reuse the sand, they only need to gently push or pull the sand collection box 206, and it can smoothly slide out of the device housing 201 along the slide rail 205. This greatly simplifies the operation process and improves work efficiency, allowing users to manage and recycle sand more easily. It achieves efficient sandblasting of metal tools and maximizes the utilization of sand, reducing resource waste and embodying the concept of green and environmentally friendly manufacturing. At the same time, this design also improves the flexibility and practicality of the device, enabling it to better adapt to the diverse needs of different users.

[0040] In actual operation, when this device is in use, the motor 102 plays a core role in providing power. When the motor 102 starts, its output shaft begins to rotate and transmits power to the first synchronous pulley 103. The first synchronous pulley 103 then begins to rotate, and the teeth or grooves on its rim mesh with the inner teeth of the synchronous belt 105, thereby driving the synchronous belt 105 to rotate cyclically. The synchronous belt 105 is tightly fitted between the first synchronous pulley 103 and the second synchronous pulley 106, ensuring smooth power transmission. When the synchronous belt 105 is driven to rotate by the first synchronous pulley 103, it drives the second synchronous pulley 106 to rotate at the same speed or at a speed reduced by a certain ratio. The rotation of the second synchronous pulley 106 is directly related to the rotation of the rotating tube 108. The inner wall of the rotating tube 108 is tightly connected to the second synchronous pulley 106. Therefore, when the second synchronous pulley 106 rotates... When rotating, the rotating tube 108 also rotates, and the rotation of the rotating tube 108 ultimately drives the rotation of the sandblasting assembly 109. The sandblasting assembly 109 typically includes a nozzle, a sand conveying system, etc., and is used to spray sand at high speed onto the surface of the metal tool to achieve cleaning, deburring, and increasing surface roughness. Driven by the rotating tube 108, the sandblasting assembly 109 can rotate within the device housing 201, thereby achieving all-round sandblasting treatment of the metal tool surface. The sandblasting device drives the synchronous pulley 103, synchronous pulley 106, and synchronous belt 105 through the motor 102, achieving smooth and efficient driving of the rotating tube 108 and the sandblasting assembly 109, thus completing the sandblasting treatment of the metal tool. This design not only improves sandblasting efficiency but also reduces noise and maintenance costs, providing a reliable technical means for the surface treatment of metal tools.

[0041] In addition, a placement plate 202 is carefully designed inside the device housing 201, with a discharge port 203 on its surface. This allows excess sand to flow smoothly through these discharge ports 203 after sandblasting and fall into a specially configured funnel 204 at the bottom of the placement plate 202. The shape and angle of the funnel 204 are precisely calculated to ensure that the sand flows smoothly and centrally into the sand collection box 206 below. As a key component for collecting and processing sand, the sand collection box 206 has sliders 207 installed on both sides for easy cleaning and replacement by the user. These sliders 207 are connected to a pre-set slide rail 2 inside the device housing 201. The perfect fit of 05 forms a stable yet flexible sliding connection. When the user needs to clean the sand collection box 206 or reuse the sand, they only need to gently push or pull the sand collection box 206, and it can smoothly slide out of the device housing 201 along the slide rail 205. This greatly simplifies the operation process, improves work efficiency, and allows users to manage and recycle sand more easily. It achieves efficient sandblasting of metal tools, maximizes the utilization of sand, reduces resource waste, and embodies the concept of green and environmentally friendly manufacturing.
