Description

Technical Field

[0001] This utility model belongs to the technical field of centrifugal casting equipment, specifically relating to a spraying and cleaning device for a horizontal centrifugal casting machine cylinder. Background Technology

[0002] Pipe fittings with a length greater than their diameter are typically produced using horizontal centrifugal casting machines. During the centrifugal casting process, the inner wall of the mold cylinder of the horizontal centrifugal casting machine needs to be ground before each casting, and then a release agent is sprayed into the mold cylinder. To prevent the centrifuged pipe from sticking to the inner wall of the mold cylinder after casting, the coating adhering to the inner wall of the mold cylinder needs to be cleaned before each casting. After cleaning, a high-temperature coating is sprayed onto the inner wall of the mold cylinder before the next centrifugal casting. Typically, a single horizontal centrifugal casting machine can cast pipe fittings of different specifications by using different types of mold cylinders. This requires existing cleaning and spraying equipment to be able to automatically complete the cleaning and spraying operations for different types of mold cylinders simultaneously.

[0003] Current spray cleaning devices typically employ an operating platform arranged along the axial direction of the mold cylinder. A motor drives a rod-shaped spray cleaning device to move back and forth along an axial track, allowing the device to extend into the mold cylinder and complete the operation. The disadvantages of existing spray cleaning devices are: firstly, they occupy a large production space and are long; secondly, the working environment contains residue that easily adheres to the track, affecting the device's movement. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects in the prior art and provide a horizontal centrifugal casting machine spraying and cleaning device to solve the problems of large production space occupation and low operation efficiency caused by the easy impact of cleaning residue on the track.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a horizontal centrifugal casting machine spraying and cleaning device, comprising a trolley, a motor, a cylinder, a track, a spraying assembly, and a cleaning assembly. The track is a frame structure, fixed to the ground radially along the mold cylinder of the centrifugal casting machine. The wheels of the trolley are adapted to the track. The motor is fixed on the output shaft of the trolley, and a gear is installed that meshes with a rack on the track to make the trolley move along the track. The trolley has a double-layer frame structure. The lower frame is used to install the wheels and the motor. The lower frame and the upper platform are connected by a telescopic support rod. A screw jack is installed between the lower frame and the upper platform, and the upper platform is raised by the screw jack. On the upper platform, spraying and cleaning components are arranged at intervals along the axial direction of the mold cylinder. The spraying and cleaning components are driven by cylinders to move along the axial direction of the mold cylinder. The spraying component includes a nozzle, a spraying rod, and a spraying can. The nozzle is installed at the front end of the spraying rod, and the nozzle and the spraying can are connected along the spraying rod by a hose. The tail end of the spraying rod is fixedly connected to the piston rod of the cylinder by a connecting plate. The spraying rod is mounted on the upper platform by support rollers. The cleaning component includes a cleaning brush and a cleaning rod. The cleaning brush is installed at the front end of the cleaning rod, and the tail end of the cleaning rod is fixedly connected to the piston rod of the cylinder by a connecting plate. The cleaning rod is mounted on the upper platform by support rollers.

[0006] Further optimization involves a track length greater than the diameter of the molded cylinder, with the cylinder fixed axially on the upper platform, the fixed end of the cylinder facing the molded cylinder, and the extended end away from the molded cylinder.

[0007] Further optimization involves making the spraying rod and cleaning rod into square tubes, and the supporting rollers include two rollers arranged vertically and vertically, and roller fixing plates. The two supporting rollers are arranged as a group on both sides of the square tube, and the spraying rod and cleaning rod pass through the two rollers of their respective supporting rollers.

[0008] Further optimization involves equipping the spray can with a cycloidal pinwheel and a stirrer driven by a reducer to keep the carrier in the paint in a suspended state. The spray can is connected to a compressed air tank via an air pipe and a regulating valve, and the compressed air forces the paint in the spray can into the nozzle for atomization and spraying.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] 1. It has a compact structure, reasonable layout, and occupies little space.

[0011] 2. It adopts cylinder drive and support roller support to avoid the drawbacks of track movement and improve work efficiency.

[0012] 3. Even spraying and thorough cleaning reduce labor intensity. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. The term "first side" as used herein refers to... Figure 3 The left side of the view direction, the tail side refers to Figure 3 To the right of the view direction.

[0018] like Figures 1 to 3 As shown, this utility model provides a horizontal centrifugal casting machine spraying and cleaning device, including a trolley 2, a motor 9, a cylinder 5, a track 1, a spraying component 4, and a cleaning component 3. The track 1 is a frame structure, including three strip profiles arranged radially along the mold cylinder of the centrifugal casting machine, and two other strip profiles perpendicular to these three strip profiles, forming the frame structure. The first and last strip profiles are I-beams, and the wheels of the trolley are adapted to them. A rack is fixed to the side of the middle strip profile. The motor 9 is fixed to the output shaft of the trolley 2, and a gear is installed that meshes with the rack on the track 1 to make the trolley 2 move along the track 1. The lower part of the track 1 is fixed to the ground. The length of the track 1 is greater than the diameter of the mold cylinder, so that the movement of the trolley 2 along the track 1 can cover the area inside the mold cylinder.

[0019] The trolley 2 has a double-layer frame structure. The lower frame 202 is used to install wheels and motor 9. The lower frame 202 and the upper platform 204 are connected by telescopic support rods 201 at the four corners. A screw jack 203 is installed between the lower frame 202 and the upper platform 204 to raise and lower the upper platform 204. Spraying components 4 and cleaning components 3 are arranged at intervals along the axial direction of the mold cylinder on the upper platform 204. The spraying components 4 and cleaning components 3 are driven by cylinders 5 to move along the axial direction of the mold cylinder. The cylinders 5 are fixed to the upper platform 204 in the opposite direction along the axial direction of the mold cylinder, that is, the fixed end of the cylinder 5 faces the mold cylinder side, and the extended end of the cylinder 5 is away from the mold cylinder side.

[0020] The spraying assembly 4 includes a nozzle 401, a spraying rod 404, and a spray can 402. The nozzle 401 is installed at the head end of the spraying rod 404. The nozzle 401 and the spray can 402 are connected along the spraying rod 404 via a hose 403. The tail end of the spraying rod 404 is fixedly connected to the piston rod end of the cylinder 5 via a connecting plate 6. The spraying rod 404 is a square tube, and the hose 403 passes through the square tube, with one end connected to the nozzle 401 and the other end extending out of the square tube and connected to the spray can 402. The spraying rod 404 is mounted on the upper platform 204 via support rollers 7. The support rollers 7 include two rollers arranged vertically and a roller fixing plate. The two support rollers 7 are arranged in a group on both sides of the head and tail of the spraying rod 404. The spraying rod 404 passes between the upper and lower rollers of the support rollers 7, which provide support and do not interfere with the movement of the spraying rod 404. The spray can 402 is equipped with a cycloidal pinwheel and a stirrer driven by a reducer, ensuring that the carrier in the paint remains suspended. The spray can 402 is connected to a compressed air tank via an air pipe and a regulating valve. The compressed air forces the paint in the spray can 402 into the nozzle 401 for atomization and spraying. The pressure of the compressed air entering the spray can 402 is adjusted by the regulating valve as needed, controlling the pressure between 0.15 and 0.3 MPa. Two spray cans 402 can be configured to operate simultaneously, or a single unit can operate independently.

[0021] The cleaning assembly 3 includes a cleaning brush 301 and a cleaning rod 302. The cleaning brush 301 is installed at the front end of the cleaning rod 302, and the tail end of the cleaning rod 302 is fixedly connected to the piston rod end of the cylinder 5 via a connecting plate 6. The cleaning rod 302 is mounted on the upper platform 204 via support rollers 7. The cleaning rod 302 is a square tube, and the support rollers are arranged in pairs on both sides of the cleaning rod 302. The cleaning rod 302 passes between the two rollers of the support rollers 7, which provide support and do not interfere with the movement of the cleaning rod 302.

[0022] After the cast part is removed from the mold of the centrifugal casting machine 8, the mold continues to rotate. The residual coating on the inner wall of the mold is removed by the cleaning brush 301. First, the upper platform 204 is raised to a suitable height by manually adjusting the screw jack 203 of the trolley 2. Then, the cleaning component 3 is moved back and forth by the cylinder 5 so that the cleaning brush 301 is in the predetermined position for cleaning the mold. Then, the gear moves along the rack by the motor 9 and the reducer, so that the trolley 2 moves back and forth on the track 1 to remove the residual coating on the inner wall of the mold.

[0023] After cleaning, the coating is sprayed onto the inner wall of the mold cylinder, which has a certain temperature, using the spraying assembly 4. First, the upper platform 204 is raised to a suitable height by manually adjusting the screw jack 203 of the trolley 2. Then, compressed air is introduced to force the evenly stirred coating in the spray tank 402 into the hose 403. After being atomized by the nozzle 401, it is sprayed onto the inner wall of the mold cylinder, which is rotating at a low speed. At the same time, the trolley 1 is driven by the motor 9, which makes the trolley 2 move back and forth along the track 1, so as to achieve uniform coating of the coating on the inner wall of the mold cylinder.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
