Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a shot blasting machine used in casting production. Background Technology

[0002] A shot blasting machine for castings is a mechanical device that uses a high-speed shot stream to clean and strengthen the surface of castings. It is widely used in industries such as casting, forging, and machinery manufacturing. Its core function is to remove impurities such as oxide scale, rust, sand particles, and burrs from the surface of castings through the impact of the shot, while improving the mechanical properties and appearance quality of the casting surface.

[0003] Drum shot blasting is a common type of shot blasting. Drum shot blasting machines utilize the synergy between mechanical drive and the kinetic energy transfer of the shot to propel the shot at high speed and multiple angles onto the workpiece surface, achieving cleaning and strengthening effects. The core of drum shot blasting lies in balancing kinetic energy transfer efficiency with the uniformity of workpiece tumbling. It is suitable for surface treatment of small to medium-sized castings, forgings, and heat-treated parts. In practical applications, the shot parameters and drum speed need to be optimized according to the workpiece material, size, and cleaning requirements to obtain the best results.

[0004] In the prior art, a utility model patent with the authorized public account number CN 221065922 U discloses a shot blasting machine for castings, including a base, a first vertical plate, an extension plate, a rotating shaft, a bearing, and a rotating chamber. The base has a first vertical plate and a second vertical plate respectively at both ends. The first vertical plate and the second vertical plate have a bearing installed near the top through a through groove. The rotating shaft is sleeved inside the bearing. The rotating chamber is connected between the rotating shafts. Although it has a structure that can easily dampen the shock, it can improve the stability of the shot blasting machine chamber when rotating.

[0005] However, the shock absorption structure in its device has a poor shock absorption effect during the operation of the rotating bin (hopper) and cannot meet the shock absorption requirements of the hopper. In addition, the workpiece can only be simply flipped inside the hopper, and the uniformity of the contact between the shot and the workpiece can be further improved. Utility Model Content

[0006] The purpose of this invention is to provide a shot blasting machine for casting production, which can effectively reduce the vibration of the hopper during operation, improve the stability of the shot blasting machine hopper when rotating, and allow the material to tumble inside the hopper while performing intermittent lateral movement, thereby improving the uniformity of the contact between the shot and the workpiece, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine for casting production, comprising a hopper, with upright plates on both sides of the hopper, a base plate fixedly connected to the bottom of the upright plates, a horizontal cylinder provided above the interior of the upright plates, the horizontal cylinder being connected to the upright plates via a support assembly, a sleeve plate fixedly fitted to the outer wall of the hopper, a support plate fixedly connected to the bottom of the sleeve plate, a pair of elastic cylinders fixedly fitted to one side surface of the support plate, a U-shaped rod provided inside the elastic cylinder, the U-shaped rod being fixedly connected to the base plate, a motor fixedly fitted to the inner wall of the support plate, a rotating rod fixedly fitted to the output shaft of the motor, a gear fixedly fitted to the outer wall of the rotating rod, a gear ring meshing above the gear, the inner wall of the gear ring being fixedly connected to the hopper, and a shot blaster provided on one side of the upright plate away from the hopper, the shot blaster being fixedly connected to the upright plate via a bracket.

[0008] Preferably, the support assembly includes a reciprocating screw, which is slidably connected inside the other side of the cross cylinder. The reciprocating screw is fixedly connected to the hopper. A first cylinder is fixedly sleeved on the outer wall of the cross cylinder. A second cylinder is sleeved on the outer wall of the first cylinder. The second cylinder is connected to the first cylinder by a first bolt. An elastic sleeve is fixedly sleeved on the outer wall of the second cylinder. A second square frame is fixedly sleeved on the outer wall of the elastic sleeve. A first square frame is sleeved on the outer wall of the second square frame. The second square frame is connected to the first square frame by a second bolt. The first square frame is fixedly connected to the upright plate. Both ends of the outer wall of the first cylinder are rotatably connected to rings. Multiple square rods are fixedly connected to the surface of the hopper near the rings. Square cylinders are sleeved on the outer walls of the square rods. The square cylinders are fixedly connected to the hopper.

[0009] Preferably, auxiliary components are provided on both sides of the elastic sleeve. The auxiliary components include two pairs of strips, which are respectively the two sides of the first square frame. Abutment strips are fixed to the surface of the elastic sleeve on the strips, and the abutment strips abut against the elastic sleeve. The strips are connected to the first square frame by a third bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This shot blasting machine for casting production has the following advantages over traditional technology: Through the coordination of the hopper, vertical plate, base plate, horizontal cylinder, motor, support plate, shot blaster, bracket, and support components, the operator first puts an appropriate amount of castings to be shot blasted into the hopper, then closes the hopper door on the front side, and then starts the motor and shot blaster. When the shot blaster is running, it can perform shot blasting on the castings inside the hopper. When the motor is running, it can make the hopper rotate. During this process, the elastic sleeve can buffer and dampen the hopper during operation, reducing the vibration intensity of the hopper when rotating, so that the hopper can operate stably for a long time. In addition, since the reciprocating screw is slidably connected to the horizontal cylinder, it can also perform lateral intermittent oscillation while the hopper is rotating. In this way, while the casting material is tumbling inside the hopper, it can also perform lateral intermittent movement, thereby improving the uniformity of the shot contact with the workpiece.

A support plate 6 is fixedly connected to the bottom of the sleeve plate 23, and one side surface of the support plate 6 is fixed... A pair of elastic cylinders 24 are connected. Both the elastic cylinders 24 and the elastic sleeves 14 are polyurethane elastomers, which are elastic objects made of polyurethane material. Polyurethane is a polymer compound formed by the reaction of isocyanate and polyol. Through specific formula design and processing technology, the polyurethane elastomers combine the elasticity of rubber and the strength of plastic, and have excellent elasticity. After being deformed by external force, they can quickly return to their original shape. For example, in some shock absorption devices, polyurethane elastomers can effectively absorb and release energy, reducing the impact force on equipment or structures. The elastic cylinder 24 has a U-shaped rod 25 inside. The outer wall of the U-shaped rod 25 is in contact with the inner wall of the elastic cylinder 24. The U-shaped rod 25 is fixedly connected to the base plate 3. The inner wall of the support plate 6 is fixedly connected to a motor 5. The motor 5 is a type of servo motor. The specific model is not limited, as long as it meets the requirements. The housing of the motor 5 is fixedly connected to the support plate 6. The power cord of the motor 5 is connected to an external power supply device. The output shaft of the motor 5 is fixedly connected to a rotating rod 26. The outer wall of the rotating rod 26 is fixedly sleeved with a gear. 27. Gear 27 is meshed with a gear ring 28 above it. The inner wall of gear ring 28 is fixedly connected to the hopper 1. A shot blaster 7 is provided on one side of the vertical plate 2 away from the hopper 1. A shot blaster is a mechanical device that uses a high-speed rotating impeller to accelerate and project shot (such as steel shot, cast steel shot, wire cut shot, etc.) to clean, strengthen or change the surface condition of a workpiece. The output pipe of shot blaster 7 is located inside the hopper 1. The output pipe of shot blaster 7 is clearance-fitted with the inner wall of one side of the horizontal cylinder 4. Shot blaster 7 is fixedly connected to vertical plate 2 through bracket 8.

[0016] Furthermore, the support assembly includes a reciprocating screw 9, which is slidably connected inside the other side of the horizontal cylinder 4. The reciprocating screw 9 is fixedly connected to the hopper 1. A first cylinder 10 is fixedly sleeved on the outer wall of the horizontal cylinder 4. A second cylinder 11 is fitted on the outer wall of the first cylinder 10. The inner wall of the second cylinder 10 is clearance-fitted with the outer wall of the first cylinder 10. The second cylinder 11 is connected to the first cylinder 10 by a first bolt 12. An elastic sleeve 14 is fixedly sleeved on the outer wall of the second cylinder 11. A second square frame 16 is fixedly sleeved on the outer wall of the elastic sleeve 14. The outer wall of the second square frame 16 is fitted with... A first square frame 15 is installed, and a second square frame 16 is connected to the first square frame 15 by a second bolt 17. The first square frame 15 is fixedly connected to the upright plate 2. Both ends of the outer wall of the first cylinder 10 are rotatably connected to a ring 13. The ring 13 is rotatably connected to the first cylinder 10 by a ball bearing. Multiple square rods 21 are fixedly connected to the surface of the ring 13 against the hopper 1. A square tube 22 is sleeved on the outer wall of the square rod 21. The square tube 22 is fixedly connected to the hopper 1. The outer wall of the square rod 21 and the inner wall of the square tube 22 are clearance fit. Clearance fit refers to a fit with clearance (including a minimum clearance equal to zero).

[0017] Furthermore, auxiliary components are provided on both sides of the elastic sleeve 14. The auxiliary components include two pairs of strips 19, which are respectively on both sides of the first frame 15. Abutment strips 18 are fixed to the surface of the strips 19 against the elastic sleeve 14. The abutment strips 18 are pressed against the elastic sleeve 14. The strips 19 are connected to the first frame 15 by a third bolt 20. The abutment strips 18 are pressed against the elastic sleeve 14, providing a certain damping effect for the elastic sleeve 14, thereby buffering and reducing shock in the hopper 1 during operation.

[0018] In use, the operator first opens the front door of hopper 1, puts an appropriate amount of castings to be shot blasted into hopper 1, then closes the front door of hopper 1, and then starts motor 5 and shot blaster 7. Motor 5 rotates hopper 1, and shot blaster 7 performs shot blasting on the castings inside hopper 1, ensuring the shot is evenly applied to the casting surface. During this process, the abutment plate 18 abuts against the elastic sleeve 14, providing a damping effect to the elastic sleeve 14, thereby buffering and reducing vibration of hopper 1 during operation, reducing the vibration intensity of hopper 1 during rotation, so that hopper 1 can operate stably for a long time. Furthermore, due to... The reciprocating screw 9 is slidably connected to the cross cylinder 4. While the hopper 1 rotates, it can also perform intermittent lateral oscillation. In this way, while the casting material is tumbling inside the hopper 1, it can also perform intermittent lateral movement, thereby improving the uniformity of the shot contact with the workpiece. After the elastic sleeve 14 ages after long-term use and affects the shock absorption effect, the maintenance personnel can rotate the first bolt 12, the second bolt 17 and the third bolt 20 counterclockwise to disassemble the output shaft of the motor 5 from the cross cylinder 4, so that the housing of the motor 5 is separated from the support plate 6, and the elastic sleeve 14 can be taken out from the first square 15 for replacement, so as to ensure the stable operation of subsequent shot blasting.
