Description

Technical Field

[0001] This utility model belongs to the field of pipe bending machine technology, specifically relating to a fixed conveying mechanism for a fully automatic pipe bending machine. Background Technology

[0002] Pipe bending machines are indispensable equipment in the pipe processing industry. They are mainly used for the precise bending of metal or plastic pipes to meet the diverse needs of various industrial sectors for pipeline systems. Pipe bending machines are mainly divided into two types: CNC pipe bending machines and hydraulic pipe bending machines. CNC pipe bending machines control the bending process through a CNC system and are suitable for occasions requiring high-precision bending. Hydraulic pipe bending machines, on the other hand, use a hydraulic system to provide power and are suitable for on-site construction and easy operation.

[0003] Currently, a common problem encountered when using pipe bending machines to process pipes is that the surface material of the pipe cannot withstand the stress due to excessive tensile force, which can lead to cracking or even breakage. Utility Model Content

[0004] The purpose of this invention is to provide a fixed conveying mechanism for a fully automatic pipe bending machine, which can effectively protect the integrity of the pipe during the bending process and prevent the pipe from cracking or breaking due to excessive tensile force.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A fixed conveying mechanism for a fully automatic pipe bending machine includes a conveying plate and an oil storage tank. An air pump is fixedly connected to the top of the conveying plate, and a first semi-circular clamping block is fixedly connected to the piston rod of the air pump. A first sliding groove for cooperating with the first semi-circular clamping block is formed on the top of the conveying plate, and the bottom of the first semi-circular clamping block is in contact with the first sliding groove. A second semi-circular clamping block for cooperating with the first semi-circular clamping block is fixedly installed on the top of the conveying plate. Multiple springs are fixedly connected to opposite sides of both the first and second semi-circular clamping blocks, and a sponge block is fixedly installed on one side of each spring. A fixed spraying assembly is located on the top of the conveying plate, corresponding to the positions of the first and second semi-circular clamping blocks. A control panel is installed on one side of the oil storage tank, and an oil inlet pipe is connected to the top of the oil storage tank. A water pump is fixedly installed on one side of the oil storage tank. A second conveying pipe is fixedly connected to the water inlet of the water pump, and one end of the second conveying pipe is connected to the oil storage tank. The water outlet of the water pump is connected to the first conveying pipe, and one end of the first conveying pipe is connected to the fixed spraying assembly.

[0007] Preferably, the fixed spraying assembly includes multiple sets of rolling columns installed on the top of the conveyor plate. Each set of rolling columns has a second slider groove at its bottom. The top of the second slider groove has multiple threaded holes arranged in an array. The bottom of one side of the rolling column is threaded to one of the threaded holes. A semi-circular annular tube is fixedly connected to the top of the conveyor plate and between two sets of rolling columns. The bottom of the semi-circular annular tube is connected to multiple spray nozzles.

[0008] Preferably, the plurality of nozzles are arranged in a circumferential array at the bottom of the semi-circular tube, and each nozzle is fixedly connected to a solenoid valve at one end near the semi-circular tube.

[0009] Preferably, a collection box is fixedly installed at the bottom of the conveyor plate corresponding to the position of the semi-circular annular tube, a built-in filter screen is fixedly installed at the top of the collection box, and an oil outlet pipe is connected to one side of the collection box.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a fixed conveying mechanism for a fully automatic pipe bending machine. By setting a fixed spraying component, the pipe is wiped by the synergistic action between the first and second semicircular clamping blocks and the sponge block, which facilitates the initial cleaning of the pipe. The second slider groove fixes each set of rolling columns to the width of the steel pipe, so that it clamps and conveys the pipe to the bottom of the semicircular annular tube.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 - Figure 4 As shown, a fixed conveying mechanism for a fully automatic pipe bending machine includes a conveying plate 1 and an oil storage tank 14. An air pump 2 is fixedly connected to the top of the conveying plate 1. A first semi-circular clamping block 3 is fixedly connected to the piston rod of the air pump 2. A first sliding block groove 5, which cooperates with the first semi-circular clamping block 3, is opened on the top of the conveying plate 1, and the bottom of the first semi-circular clamping block 3 is in contact with the first sliding block groove 5. A second semi-circular clamping block 4, which cooperates with the first semi-circular clamping block 3, is fixedly installed on the top of the conveying plate 1. Multiple springs 6 are fixedly connected to the opposite sides of both the first semi-circular clamping block 3 and the second semi-circular clamping block 4. A sponge block 7 is fixedly installed on one side of the spring 6. A fixed spraying assembly is located on the top of the conveyor plate 1 and at the position corresponding to the first semicircular clamp 3 and the second semicircular clamp 4. A control panel is installed on one side of the oil tank 14. An oil inlet pipe 18 is connected to the top of the oil tank 14. A water pump 15 is fixedly installed on one side of the oil tank 14. The water inlet end of the water pump 15 is fixedly connected to the second conveying pipe 17, and one end of the second conveying pipe 17 is connected to the oil tank 14. The water outlet end of the water pump 15 is connected to the first conveying pipe 16, and one end of the first conveying pipe 16 is connected to the fixed spraying assembly.

[0022] The device includes a conveyor plate 1 connected to the conveying path of the pipe bending machine. An air pump 2 drives a first semi-circular clamping block 3 to slide through a first slider groove 5 to one side of a second semi-circular clamping block 4 to clamp the pipe surface. The design of the sponge block 7 allows for wiping the outer surface of the pipe as it moves, achieving initial cleaning of the pipe surface. This step ensures that subsequent spraying operations can cover the pipe surface more evenly. A water pump 15 drives the pipe bending oil in the oil storage tank 14 to be delivered to the spraying assembly through the second conveying pipe 17 and the first conveying pipe 16, enabling the spraying assembly to continuously spray the pipe according to the operation requirements, reducing the intensity of manual labor. The oil inlet pipe 18 is designed to effectively store the pipe bending oil in the oil storage tank 14. The control panel is equipped with multiple buttons and a display screen, allowing operators to start or stop the device using the buttons.

[0023] like Figure 3 and Figure 4 As shown, the fixed spraying assembly includes multiple sets of rolling columns 8 installed on the top of the conveyor plate 1. Each set of rolling columns 8 has a second slider groove 9 at its bottom. The top of the second slider groove 9 has multiple threaded holes 10 arranged in an array. The bottom of one side of the rolling column 8 is threadedly connected to one of the threaded holes 10. A semi-circular annular tube 11 is fixedly connected to the top of the conveyor plate 1 and between the two sets of rolling columns 8. The bottom of the semi-circular annular tube 11 is connected to multiple spray nozzles 12.

[0024] Specifically, the second slider groove 9 is designed to adjust the distance between the two rolling columns 8 in each group, and works in conjunction with the first semicircular clamping block 3 and the second semicircular clamping block 4 to adjust the spacing according to the pipe size; the cooperation of the two groups of rolling columns 8 ensures the clamping and conveying of the pipe, so that the pipe can pass stably from the bottom of the semicircular annular pipe 11; the driving water pump 15 conveys the bent pipe oil in the oil storage tank 14 to the semicircular annular pipe 11 through the second conveying pipe 17 and the first conveying pipe 16, and then the bent pipe oil is evenly sprayed onto the surface of the pipe through multiple nozzles 12 at the bottom of the semicircular annular pipe 11.

[0025] like Figure 3 and Figure 4 As shown, multiple nozzles 12 are arranged in a circular array at the bottom of the semi-circular tube 11, and each nozzle 12 is fixedly connected to a solenoid valve 13 at one end near the semi-circular tube 11.

[0026] The circular array design allows the nozzle 12 to evenly spray oil onto the pipe surface, while the solenoid valve 13 controls the amount and position of the spray from the nozzle 12.

[0027] like Figure 3As shown, a collection box 19 is fixedly installed at the bottom of the conveyor plate 1, corresponding to the position of the semi-circular annular tube 11. An internal filter screen 20 is fixedly installed at the top of the collection box 19, and an oil outlet pipe 21 is connected to one side of the collection box 19.

[0028] Specifically, the collection box 19 is designed to collect the bent pipe oil sprayed from the nozzle 12, ensuring that the conveyor table remains clean; the built-in filter screen 20 is designed to filter the bent pipe oil that falls after spraying, preventing external impurities from entering the collection box 19 and improving the utilization rate of the bent pipe oil; the oil outlet pipe 21 is designed to discharge the bent pipe oil stored in the collection box 19, facilitating subsequent recycling and reuse.

[0029] like Figure 4 As shown, each pair of rolling columns 8 forms a group, and there are at least two groups of rolling columns 8.

[0030] The design of the two sets of rolling columns 8 effectively avoids the impact of the nozzle 12 on the pipe during the spraying process by clamping and conveying the pipe, thus preventing uneven spraying caused by pipe displacement.

[0031] like Figure 3 As shown, the semicircular annular tube 11 is in the shape of a semicircular arc, and the diameter of the semicircular annular tube 11 is greater than the diameter of the farthest distance between the first semicircular clamp 3 and the second semicircular clamp 4.

[0032] Specifically, the semi-circular arc design is used to accommodate the curvature of the pipe, and its nozzle 12 sprays in a fan shape, which can effectively spray the sides and bottom of the pipe. The design of the diameter of the semi-circular ring pipe 11 makes the mechanism applicable to various specifications of pipes, improving the applicability and flexibility of the pipe bending machine.

[0033] The working principle of this utility model is as follows: First, the operator needs to inject an appropriate amount of pipe bending oil into the oil storage tank 14, and then drive the air pump 2 to clamp the pipe into the first semi-circular clamp 3 and the second semi-circular clamp 4. The sponge block 7 is used to initially wipe the pipe. Next, the rolling column 8 is fixed to a position that matches the size of the pipe. The two rolling columns 8 clamp the pipe and slide to transport the pipe to the bottom of the semi-circular annular pipe 11. Finally, the solenoid valve 13 controls the nozzle 12 to spray the surface of the pipe, thereby completing the pipe bending oil spraying operation on the surface of the pipe.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
