Description

Technical Field

[0001] This utility model belongs to the technical field of centrifugal casting equipment, specifically relating to a horizontal centrifugal casting machine system adapted to produce blanks of roller and tube sleeve parts such as centrifugal casting rolls, composite pipes, conveying pipes and reduction tanks. Background Technology

[0002] Horizontal centrifugal casting machines are special casting equipment that uses centrifugal force to form metal castings, belonging to the basic process equipment of modern industry. The casting process involves melting metal, making a mold, pouring the liquid metal into a metal mold (single-layer / double-layer structure) or non-metal mold that rotates around a horizontal axis, and then obtaining a near-net-shape casting after centrifugal filling, shaping, cooling and solidification.

[0003] Existing horizontal centrifugal casting machines are mostly composed of individual equipment with a series of auxiliary devices such as manually operated ladle pouring and cleaning / spraying devices. The equipment needs to be operated independently and does not form a complete automated or semi-automated system. The disadvantages are: first, the integration level is low and the production area is large; second, each piece of equipment needs to be operated separately, which is complicated; and third, there is a lack of real-time monitoring of the working status of the centrifugal casting machine, resulting in poor product quality consistency. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects in the prior art and provide a horizontal centrifugal casting machine system that solves the problems of low integration, large production space occupation, complex operation, and poor product quality consistency caused by the lack of real-time monitoring of the working status of the centrifugal casting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a horizontal centrifugal casting machine system, including a casting machine body, a drive device, a pouring system, a cleaning and spraying device, a protective cover device, a cooling water circulation device, a winch discharge device, an electrical control system, and a hydraulic tilting system;

[0006] The main body of the casting machine is a roller-type horizontal centrifugal casting machine. The drive device drives the transmission belt to rotate, which provides power to the active roller of the casting machine body. A mold cylinder air cooling device, a temperature monitoring system and a dual-shaft water cooling system are installed at the mold cylinder of the casting machine body. The cooling water circulation device is connected to the dual-shaft water cooling system to provide circulating cooling water.

[0007] A track is provided on one side of the main body of the casting machine. The track is equipped with a pouring system and a winch discharge device. The pouring system includes a pouring trolley, a pouring ladle, and a pouring chute. The pouring trolley is driven by a motor to move on the track. The pouring ladle is clamped in a tilting frame and hinged to the support frame of the pouring trolley. The tilting frame, carrying the pouring ladle, is driven by a hydraulic cylinder to rotate around the support shaft, pouring the molten steel in the pouring ladle into the pouring chute. The pouring chute is hinged to the adjusting frame of the pouring trolley. The adjusting frame adjusts the position of the pouring chute to the predetermined pouring position.

[0008] On the other side of the casting machine body, there is also a track with a cleaning and spraying device. The winch discharge device includes a receiving trolley, a winch, a winch mounting base and chucks. The wheels of the receiving trolley are adapted to the track. The winch is installed on the winch mounting base. The winch controls the movement of the chucks to pull the billet out of the mold and into the receiving trolley.

[0009] The hydraulic tilting system consists of a hydraulic station, hydraulic cylinders, hydraulic pipelines, and an electrical control system, and is used to control the tilting frame to tilt the casting ladle.

[0010] The electrical control system is installed in the control cabinet, which controls the movement of the casting trolley and the spraying trolley, the rotation of the main motor, the pouring of molten steel, the forward and backward movement of the ladle and the casting chute, and the operation of the winch.

[0011] The protective cover device includes a protective canopy, a slide rail, and a cylinder. The protective canopy is pneumatically driven by the cylinder on the slide rail to cover the outside of the casting machine body during the pouring process.

[0012] Further optimization involves the casting machine body including an active support roller fixed on the base and a driven support roller that can move along the large base. The position of the driven support roller is determined according to the required diameter of the mold cylinder, so that the pouring support angle formed by the two tangent points of the outer diameter of the mold cylinder raceway and the support roller at the center of rotation of the mold cylinder is 90° to 120°.

[0013] Further optimization involves the following: the air-cooling device for the molded cylinder is an air pipe with multiple nozzles installed inside the protective canopy. Air pipes distributed along the axial direction of the molded cylinder are installed on both sides of the protective canopy. Multiple nozzles with manual valves are arranged at intervals on the air pipes. The main route of the air pipe is controlled by a solenoid valve for opening and closing.

[0014] Further optimization includes a trolley, a motor, cylinders, a spraying component, and a cleaning component. The trolley is on a track, the motor provides driving force to the trolley, and there are two cylinders that control the extension and retraction of the spraying component and the cleaning component respectively. The trolley has a height adjustment device.

[0015] Further optimization involves arranging the tracks on both sides of the casting machine body along the radial direction of the mold cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. Within the product specification range, it can centrifugally cast rolls, composite pipes, conveying pipes and reduction tanks of various lengths, diameters, weights and materials.

[0019] 3. During the centrifugal production process, it has cooling and heat preservation functions to ensure the constant temperature field inside the mold cylinder.

[0020] 4. The electrical control system adopts a computer automatic control system, which has the characteristics of fully digital intelligent control, digital detection of motor speed and closed-loop control; it can monitor and display parameters such as the temperature inside the mold cavity, the vibration of the mold rotation drive device and the mold rotation speed. The mold rotation can be adjusted by inching control, which facilitates the lifting of the mold. Attached Figure Description

Detailed Implementation

[0028] 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, and 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.

[0029] like Figure 1 As shown, this utility model provides a horizontal centrifugal casting machine system, including a casting machine body 1, a drive device 9, a pouring system 2, a cleaning and spraying device 3, a protective cover device 4, a cooling water circulation device 6, a winch discharge device, an electrical control system 5, and a hydraulic tilting system.

[0030] like Figure 2 and Figure 3 As shown, the main body 1 of the casting machine is a horizontal centrifugal casting machine with idler rollers. The drive device 9 drives the transmission belt 104 to rotate, providing power to the active support rollers 102 of the main body 1. A mold cylinder air-cooling device, a temperature monitoring system, and a dual-shaft water-cooling system are installed at the mold cylinder 101 of the main body 1. A cooling water circulation device 6 is connected to the dual-shaft water-cooling system to provide circulating cooling water. The mold cylinder air-cooling device is an air pipe with multiple nozzles located inside the protective canopy. Air pipes are arranged along the axial direction of the mold cylinder on both sides of the protective canopy. Multiple nozzles with manual valves are arranged at intervals on the air pipes. The main air pipe is controlled by a solenoid valve. The bearing seats of the active support rollers 102 are fixed to the large base of the main body 1 with bolts. The two active support rollers 102 are connected by a shaft. The driven support rollers 103 have two bearing seats, which are fixed to the large base with bolts. According to the casting specifications, the bearing seat of the driven support roller 103 is adjusted radially on the large base to ensure that the optimal pouring support angle formed by the two tangent points of the outer diameter of the mold raceway and the support roller at the center of rotation of the mold cylinder is 90° to 120°. After adjustment, the bolts of the fixed bearing seat are tightened to fix the driven support roller 103 in position. The drive unit 9 transmits power to the drive shaft of the drive support roller 102 via the transmission belt 104. The drive shaft transmits power to the mold cylinder 101 by means of the friction between the support roller and the mold cylinder 101, causing the mold cylinder 101 to rotate.

[0031] like Figure 4As shown, a track is provided on one side of the casting machine body 1, arranged radially along the mold cylinder 101. A pouring system 2 and a winch discharge device are mounted on the track. The pouring system 2 includes a pouring trolley 201, a pouring ladle 202, and a pouring chute 203. The pouring trolley 201 is driven by a motor to move on the track. The pouring ladle 202 is fitted into a tilting frame 204 and hinged to the support frame of the pouring trolley 201. The tilting frame 204, carrying the pouring ladle 202, rotates around the support shaft driven by a hydraulic cylinder, discharging the molten steel from the pouring ladle 202. The casting chute 203 is poured into the casting chute 203, which is hinged to the adjusting frame of the casting trolley 201. The adjusting frame includes a screw jack on the casting trolley 201 and an adjusting support rod on the support plate of the casting chute 203 to adjust the position of the casting chute 203 to the predetermined casting position. The casting trolley 201 is equipped with an automatic weighing pressure sensor. The linear guide rail on the casting trolley 201 is driven by a right-angle reduction motor and a ball screw. The casting ladle 202 and the casting chute 203 on the platform of the casting trolley 201 can move laterally.

[0032] like Figure 5 As shown, a track is also provided on the other side of the casting machine body 1, arranged radially along the mold cylinder 101. A cleaning and spraying device 3 is provided on the track. The cleaning and spraying device 3 includes a trolley 301, a motor 302, a cylinder 303, a spraying component 305, and a cleaning component 304. The trolley 301 is on the track, and the motor 302 is fixed on the trolley 301. The gear on the shaft of the motor 302 meshes with the rack on the track to provide driving force for the trolley 301 to move along the track. There are two cylinders 303, which respectively control the extension and retraction of the spraying component 305 and the cleaning component 304. The trolley 301 has a height adjustment device to adjust the position of the spraying component 305 and the cleaning component 304 in the height direction. The trolley 301 adjusts the position of the spraying component 305 and the cleaning component 304 in the radial direction. The cylinders 303 adjust the position of the spraying component 305 and the cleaning component 304 in the axial direction, thereby realizing the adjustment of the three-dimensional coordinate system direction of the cleaning and spraying device 3.

[0033] like Figure 6 As shown, the winch discharge device includes a receiving trolley 8, a winch 7, a winch mounting base, and chucks. The wheels of the receiving trolley 8 are adapted to the track. The winch 7 is mounted on the winch mounting base. The winch controls the movement of the chucks to pull the billet out of the die cylinder 101 and onto the receiving trolley 8.

[0034] The hydraulic tilting system consists of a hydraulic station 10, hydraulic cylinders, hydraulic pipelines, and an electrical control system, and is used to control the tilting frame to tilt the casting ladle 202.

[0035] The electrical control system 5 is installed in the control cabinet and controls the movement of the casting trolley 201 and the spraying trolley, the rotation of the main motor, the pouring of molten steel, the forward and backward movement of the casting ladle 202 and the casting chute 203, and the operation of the winch 7.

[0036] The protective cover device 4 includes a protective canopy, a slide rail, and a cylinder. The protective canopy is a structure with two right-angled joints. During pouring, the protective canopy on both sides moves inward on the slide rail through the pneumatic drive of the cylinder, covering the outside of the casting machine body 1 during the pouring process. After the pouring is completed, the protective canopy on both sides moves outward on the slide rail through the pneumatic drive of the cylinder, so that the position of the mold cylinder 101 is exposed, ensuring convenient hoisting of the mold cylinder 101 with the largest specification.
