Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a tube-making machine and a tube-making method. Background Technology

[0002] Pipe-making machines are mainly divided into two categories: common high-frequency welded pipe machines and stainless steel pipe-making machines. These machines can manufacture various pipe fittings, such as stair railing pipes, security door and window pipes, and automotive exhaust pipes. Traditional pipe-making machines require the addition of raw materials during the production process to ensure normal operation. Adding too much or too large a volume of raw material can cause blockages in the feed pipe, affecting material addition and normal pipe production. Furthermore, traditional pipe-making machines have complex and inefficient grinding methods for finished pipe fittings, hindering rapid grinding and reducing the efficiency of arbitrary length cutting. In addition, the pipe-making process is complex, and the various steps are difficult to coordinate, further delaying production.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a tube-making machine for producing suspended rods in metal smelting [CN201820658838.3]. It includes a placement shell, with a tube-making machine housing fixedly connected to the upper surface of the placement shell. A feed pipe is connected to the left side of the tube-making machine housing, and an anti-blocking mechanism is provided at the right end of the feed pipe. This solution, through the setting of a limiting mechanism, utilizes the rotation of the second rotating shaft to cause the transmission belt to wind up, thereby causing the fixed block to drive the magnet block to move downwards. The magnet block's adsorption and clamping action can stably restrict tubes of different diameters. Furthermore, through the setting of an adjustment mechanism, the rotation of the second rotating shaft causes two threaded columns to rotate, thereby causing the connecting rod, under the action of the first and second pins, to move the support plate up and down, thus adjusting the clamped tube to a suitable position. This facilitates rapid grinding of the tubes, improves grinding efficiency and quality, and enhances worker safety during grinding.

[0004] The above solution has solved the problems of easy blockage at the feed inlet of the tube making machine and poor grinding effect in the existing technology to a certain extent. However, the solution still has many shortcomings, such as the difficulty in forming a continuous process between various processes, and the complexity of the tube making process, which affects production efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a tube-making machine with good processing continuity.

[0006] The purpose of this invention is to address the above-mentioned problems by providing a simple tube-making method using a tube-making machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a tube making machine, including an automatic unwinding mechanism for feeding and unwinding, a material clamping and forming component at one end of the automatic unwinding mechanism, a material cutting and welding component between the automatic unwinding mechanism and the material clamping and forming component, a material sizing and straightening structure at the end of the material clamping and forming component away from the material cutting and welding component, and a ring cutting and pushing device at one end of the material sizing and straightening structure.

[0008] The material is quantitatively fed in by an automatic unwinding mechanism, and then cut and welded by a material cutting and welding assembly for preliminary processing. Next, the material is shaped by a material clamping and forming assembly, and then shaped by a material sizing and straightening structure. Finally, the material is cut to the required length and pushed to the next process by a ring cutting and pushing equipment. This process not only has good continuity but also a high degree of automation, achieving seamless connection between production processes, improving processing efficiency, and ensuring the quality of finished pipe fittings.

[0009] In the aforementioned tube-making machine, the material cutting and welding assembly includes a five-roll leveler, an automatic plate welding machine is provided on one side of the five-roll leveler, and a movable shearing machine for cutting the material is provided on one side of the automatic plate welding machine. A welding detection mechanism is provided on the side of the movable shearing machine away from the automatic plate welding machine.

[0010] The material is leveled by a five-roller leveling machine, and then sheared at both ends by a moving shearing machine to ensure the flatness of both ends of the material.

[0011] In the aforementioned tube-making machine, the five-roll leveling machine includes a conveying roller, one end of which is provided with a positioning plate and the other end with a sliding limit plate, and the sliding limit plate is driven by a sliding servo motor. Rotary conveying motors capable of driving the conveying roller to rotate are provided on both sides of the conveying roller. The automatic plate welding machine includes a plate welding machine, with a dual-station material positioning frame on its lower side.

A linkage shaft driven by a rotary motor passes through the shaft of the conveying roller. The welding inspection mechanism includes an ultrasonic automatic inspection device installed on the upper end of the material conveying frame, and a CNC welding device is slidably installed on the material conveying frame and on one side of the ultrasonic automatic inspection device.

[0012] The clamping crossbar can flatten the upper surface of the material, and the height of the clamping crossbar can be adjusted by the lifting motor according to the material height, which is highly flexible. In addition, the material can be detected by ultrasonic automatic detection equipment, so that the CNC welding equipment can accurately weld according to the preset length.

[0013] In the aforementioned tube-making machine, the material sizing and straightening structure includes a heat treatment solution equipment. A material sizing structure is located on one side of the heat treatment solution equipment, and at least three sets of material sizing structures are provided. At least two sets of material straighteners are located at one end of the material sizing structure, with the material straighteners arranged vertically. The central axis of the material sizing structure and the central axis of the material straighteners are aligned on the same straight line. The material structure treated by the heat treatment solution equipment is more stable and the molecular structure is more uniform.

Several clamping crossbeams are sequentially arranged on one side of the material centering structure, and a material rotating unit is located at the end of each clamping crossbeam away from the material centering structure. A precision forming unit is located on one side of the material rotating unit, and a clamping device is provided between the precision forming unit and the heat treatment solution treatment equipment. A return water tank is located at the bottom of the heat treatment solution treatment equipment. The material centering structure ensures that the material remains centered during transport, preventing misalignment during subsequent processing, and the precision forming unit can perform shaping treatment on the material.

[0015] In the aforementioned tube-making machine, the ring-cutting and pushing device includes an eddy current detection device for detecting materials. The eddy current detection device is located at one end of a sliding conveyor frame, and an automatic ring-cutting device is slidably mounted on the upper end of the sliding conveyor frame. At the end of the sliding conveyor frame furthest from the eddy current detection device, a material pushing frame composed of several material pushing rollers is provided. The eddy current detection device detects the length of the material, and the automatic ring-cutting device performs real-time shearing of the material as needed.

[0016] In the aforementioned tube-making machine, the automatic unwinding mechanism includes a single-cone automatic unwinder. One end of the single-cone automatic unwinder has a feed inlet, and the other end is connected to a double-cone automatic unwinder via a material conveyor belt. Both the double-cone and single-cone automatic unwinders have receiving channels at their bottoms. These receiving channels allow dropped material to be re-transported to the feed inlet, preventing material waste.

[0017] The aforementioned tube-making machine also provides a tube-making method, which includes the following steps:

[0018] S1. Material feeding and unloading are performed via an automatic unwinding mechanism;

[0019] S2. Use the material cutting and welding assembly to cut the material at both ends and weld the materials together.

[0025] S12. The material is unloaded via a double-cone automatic unwinding machine.

[0026] S13. Receive the dropped material through the receiving channel and transport it to the feed inlet;

[0027] Step S3 specifically includes the following steps:

[0028] S31. Use a five-roll leveler to keep the material level;

[0029] S32. The material is cut at both ends using a mobile shearing machine.

[0030] S33. After the materials are cut, they are welded using CNC welding equipment.

[0035] S44. The material is subjected to solution treatment using a heat treatment solution equipment;

[0036] S45. The material is dimensionally positioned using a material sizing structure and straightened using a material straightening machine.

[0037] This method sequentially sets up an automatic unwinding mechanism, a material cutting and welding assembly, a material clamping and forming assembly, a material sizing and straightening structure, and a ring cutting and pushing device during material feeding. These devices perform unwinding and conveying, end-to-end cutting, constant pressure forming, sizing and straightening, and ring cutting and pushing on the material, respectively.
