Description

Technical Field

[0001] This invention belongs to the field of reinforced concrete pipe processing, specifically relating to a rotary core-lifting vibration pipe-making machine and a pipe-making method. Background Technology

[0002] Currently, most concrete product manufacturers typically employ a combination of radial extrusion and core mold vibration processes when producing reinforced concrete drainage pipes. For example, the German vertical radial extrusion pipe-making system utilizes a rotating mechanism to transport the outer mold between the joint forming mechanism and the inner mold. Simultaneously, a feeding mechanism discharges material while the vibrating inner mold moves upward, and a material-distributing mechanism at the top of the inner mold ensures uniform concrete distribution. After pipe production, the outer mold rotates to the outside, and a lifting mechanism drives a cleaning mechanism to clean and finish the inner wall of the concrete pipe. While this improves product quality, it also has the following drawbacks:

[0003] The cleaning mechanism requires a separate motor to drive the brush head to rotate and a lifting mechanism to drive the brush head to move up and down. When processing pipes of different diameters, the brush head and other structures also need to be replaced separately, resulting in high overall equipment cost and occupying external space of the frame.

[0004] In addition, when cleaning and repairing the inner wall of concrete pipes, the cleaning agency may cause damage to the edge of the concrete pipe opening, resulting in a rotten opening that affects product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary core-lifting vibration tube-making machine and tube-making method to solve the above-mentioned problems.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A rotary core-lifting vibration tube-making machine includes, from top to bottom, a feeding mechanism, a swivel forming mechanism, an outer mold, and a vibrating core mold, a material feeding mechanism rotatably disposed at the top of the vibrating core mold, a rotating mechanism for driving the outer mold to rotate, and a tube end lifting mechanism and a core mold lifting mechanism for driving the swivel forming mechanism and the vibrating core mold to move up and down respectively. The tube-making machine also includes a polishing mechanism.

[0008] The cleaning mechanism is vertically positioned at the end of the material feeding mechanism, and under the rotational drive of the material feeding mechanism and the linear drive of the core mold lifting mechanism, it cleans and modifies the inner wall and opening of the pipe.

[0009] The application sets the sweeping mechanism on the poking mechanism above the vibrating core mold, after the reinforced concrete cement pipe is formed, the sweeping of the pipe opening and the inner wall of the reinforced concrete pipe is completed when the vibrating core mold is lowered, compared with the sweeping mechanism and the smoothing mechanism of the prior art which are arranged above the feeding station to sweep the pipe opening and the inner wall, the application greatly saves time, improves production efficiency, reduces equipment cost, and makes the pipe opening and the inner wall of the reinforced concrete pipe smoother and more beautiful.

[0010] As a further optimization scheme of the application, the poking mechanism comprises a motor and at least two poking plates, the at least two poking plates are arranged in a ring array at the top end of the vibrating core mold and are driven by the motor, the motor is embedded in the vibrating core mold, the motor drives the rotation of the poking plates, and the uniform distribution of the concrete can be realized.

[0011] As a further optimization scheme of the application, the poking plates are arranged obliquely relative to the radius of the vibrating core mold, the distribution effect is good, and the residual concrete is avoided, the sweeping mechanism is detachably installed at the end of each poking plate and is arranged in parallel with the poking plate, and the inner wall is conveniently swept.

[0012] As a further optimization scheme of the application, the sweeping mechanism comprises a brush, the brush is connected to the end of the poking plate through a screw and a mounting plate, after the subsequent wear of the brush, the brush can be conveniently replaced, and the replacement cost is also low.

[0013] A method for forming a pipe by using the above-mentioned rotating core lifting and vibrating pipe forming machine, comprising the following pipe forming steps:

[0014] S1. The feeding mechanism transports the concrete into the outer mold;

[0015] S2. The core mold lifting mechanism lifts the vibrating core mold, the poking mechanism at the top end of the vibrating core mold driven to rotate by the motor, and the sweeping mechanism into the outer mold, the upward movement and rotation of the poking mechanism uniformly distribute the concrete into the cavity between the outer mold and the vibrating core mold;

[0016] S3. After the pipe to be formed is preliminarily formed, the core mold lifting mechanism drives the vibrating core mold, the poking mechanism at the top end of the vibrating core mold driven to rotate, and the sweeping mechanism to move downward, the downward movement and rotation of the sweeping mechanism sweep and modify the inner wall and the pipe opening of the pipe to be formed;

[0017] S4. The rotating mechanism drives the outer mold and the formed pipe to rotate to the outside, and the formed pipe is demolded to complete the pipe forming.

[0018] As a further optimization scheme of the application, before and after feeding, the pipe opening lifting mechanism drives the pipe opening forming mechanism to move downward and is clamped at the top end of the outer mold, so as to fix the outer mold and the formed pipe opening.

[0019] After the inner wall and the pipe opening of the pipe are cleaned and decorated, the pipe opening lifting mechanism drives the pipe opening forming mechanism to move upward and separate from the outer mold, so that step S4 is performed, so that when the cleaning and decorating mechanism cleans and decorates the inner wall and the pipe opening of the pipe, the pipe opening forming mechanism protects the end face of the pipe opening, and the brush will not damage the edge of the pipe opening when rotating, and will not cause a rotten opening, so that the pipe manufacturing quality is higher.

[0020] The beneficial effects of the present application are:

[0021] The present application sets the cleaning mechanism on the material pushing mechanism above the vibrating core mold, after the reinforced concrete cement pipe is formed, the cleaning of the pipe opening and the inner wall of the reinforced concrete pipe is completed when the vibrating core mold is lowered, compared with the cleaning mechanism and the polishing mechanism of the prior art which are arranged above the feeding station to clean and polish the pipe opening and the inner wall, the present application greatly saves time, improves production efficiency, reduces equipment cost and reduces equipment floor area.

[0022] The present application sets the cleaning mechanism on the material pushing mechanism above the vibrating core mold, when processing pipes with different inner diameters, the core mold can be replaced at the same time, and the corresponding size of the cleaning mechanism can be replaced, compared with the prior art, the replacement operation is also simplified, the replacement efficiency is improved, and the labor cost is reduced.

[0023] When the cleaning mechanism is used to clean and decorate the inner wall and the pipe opening of the pipe, the pipe opening forming mechanism is still located at the pipe opening, which can protect the end face of the pipe opening, so that the edge of the pipe opening will not be damaged when the brush rotates, and a rotten opening will not be caused, so that the pipe manufacturing quality is higher.

[0034] Example 1

[0035] like Figures 1-7 As shown, a rotary core-lifting vibratory tube-making machine includes a frame 1 installed in a machine pit 11, a feeding mechanism 2, a tongue-forming mechanism 3, an outer mold 4, and a vibrating core mold 5 arranged sequentially from top to bottom on the frame 1, a feeding mechanism 6 rotatably mounted on the top of the vibrating core mold 5, a rotating mechanism 7 driving the outer mold 4 to rotate, a tube end lifting mechanism 8 and a core mold lifting mechanism 9 mounted on the frame 1 and respectively driving the tongue-forming mechanism 3 and the vibrating core mold 5 to move up and down, and a polishing mechanism 10 vertically mounted at the end of the feeding mechanism 6; wherein,

[0036] The feeding mechanism 2 includes a hopper and a feeder. The input end of the feeder corresponds to the hopper, and the output end corresponds to the top opening of the outer mold 4.

[0037] The following improvements have been made to the swivel forming mechanism 3 of the German vertical radial extrusion tube forming mechanism: the overall structure is a square structure, and guide sleeves 13 are provided on both sides. The guide sleeves 13 are slidably set on the frame 1, which can make the entire swivel forming mechanism 3 move up and down stably, and the swivel is smooth and does not shake.

[0038] Compared with the rotating mechanism of the German vertical radial extrusion pipe making device arranged in the pit, the rotating mechanism 7 of the present application is arranged on the platform above the pit 11, and a plurality of rollers 12 are uniformly distributed at the bottom, facilitating the overall installation of the rotating mechanism 7, the adjustment of the level and the height, and the smooth and stable rotation;

[0039] The pipe mouth lifting mechanism 8 and the core mold lifting mechanism 9 both adopt two hydraulic cylinders distributed on both sides of the rack 1, which stably work up and down under the guidance of the guide column;

[0040] The stirring mechanism 6 includes a motor 62 and at least two stirring plates 61, and three stirring plates 61 are adopted in the embodiment. The three stirring plates 61 are arranged in an annular array at the top end of the vibrating core mold 5 and are driven by the motor 62. The motor 62 is embedded in the vibrating core mold 5. The motor 62 drives the stirring plate 61 to rotate, which can realize uniform distribution of the concrete. The stirring plate 61 is arranged obliquely relative to the radius of the vibrating core mold 5, which has good distribution effect and avoids concrete residue;

[0041] The light sweeping mechanism 10 is detachably installed at the end of each stirring plate 61 and is arranged in parallel with the stirring plate 61. The light sweeping mechanism 10 is driven to rotate by the stirring mechanism 6 and is driven linearly by the core mold lifting mechanism, so as to clean and decorate the inner wall of the pipe and the pipe mouth.

[0042] The light sweeping mechanism 10 includes a brush 101 connected to the end of the stirring mechanism 6 through a screw 103 and a mounting plate 102. After the subsequent brush 101 is worn, it can be conveniently disassembled and replaced, and the replacement cost is also low. The brush 101 can also be replaced by other structures capable of decorating the inner wall of the pipe.

[0043] When the core mold is replaced and maintained, the core mold station can be accessed from the ladder and the entrance on one side of the square pit 11.

[0044] A method for making pipes by using the above-mentioned rotating core lifting and vibrating pipe making machine includes the following pipe making steps:

[0045] S1. The pipe mouth lifting mechanism 8 drives the pipe mouth forming mechanism 3 to move downward and is clamped at the top end of the outer mold 4 to fix the outer mold 4. The feeding mechanism 2 transports the concrete into the outer mold 4.

[0046] S2. The core mold lifting mechanism lifts the vibrating core mold 5, the stirring mechanism 6 at the top end of the vibrating core mold 5 driven to rotate by the motor 62, and the light sweeping mechanism 10 into the outer mold 4. The stirring mechanism 6 that moves upward and rotates uniformly distributes the concrete into the cavity between the outer mold 4 and the vibrating core mold 5. The pipe mouth forming mechanism 3 is pressed and rubbed while moving downward to form the designed shape of the pipe mouth.

[0047] S3. After the pipe to be made is preliminarily formed, the core mold lifting mechanism drives the vibrating core mold 5 and the top-end rotating material pushing mechanism 6 and the light sweeping mechanism 10 to move down, at this time, the pipe mouth forming mechanism 3 does not move up first, the light sweeping mechanism 10 which moves down and rotates sweeps and modifies the inner wall and the pipe mouth of the pipe to be made;

[0048] S4. The pipe mouth lifting mechanism 8 drives the pipe mouth forming mechanism 3 to move up and separate from the outer mold 4, the rotating mechanism 7 drives the outer mold 4 and the forming pipe to rotate to the outside, and the forming pipe is demolded to complete the pipe making.

[0049] The application sets the light sweeping mechanism 10 on the material pushing mechanism 6 above the vibrating core mold 5, after the reinforced concrete cement pipe is formed, the vibrating core mold 5 is lowered at the same time to complete the light sweeping of the pipe mouth and the inner wall of the reinforced concrete pipe, compared with the sweeping mechanism and the light smoothing mechanism of the prior art which are placed above the feeding station to perform the light sweeping of the pipe mouth and the inner wall, the application greatly saves time, improves production efficiency, reduces equipment cost, reduces equipment floor area, the machine pit 11 area is also reduced accordingly, and the pipe mouth and the inner wall of the reinforced concrete pipe are smoother and more beautiful.

[0050] In addition, after the pipe is preliminarily formed, the pipe mouth forming mechanism 3 does not move up first, and serves as a protection structure of the pipe mouth end face when the light sweeping mechanism 10 works, so that the brush 101 does not damage the pipe mouth edge when rotating, does not cause a rotten mouth, and the pipe making quality is higher.

[0051] The above-mentioned embodiments only express several embodiments of the application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which belong to the protection scope of the application.
