Description

Technical Field

[0001] This invention belongs to the field of piercing machine technology, and particularly relates to a piercing machine for seamless tubes made of light metal alloys and its working method. Background Technology

[0002] An electrical discharge machining (EDM) drilling machine is a machine tool that uses the principle of electrical discharge machining to process holes smaller than 5mm. It is used for processing small and medium-sized punch dies. Its processing characteristic is that it is not limited by the hardness of the metal material; the die can be pre-hardened before the machine processes the required hole shape to ensure quality and extend service life.

[0003] A search revealed that application number CN202120147085.1 discloses a perforating machine, including a base and a support platform. A moving mechanism is provided between the base and the support platform to allow relative movement between them. The moving mechanism includes a slide rail, on which a dust cover that extends and retracts with the movement of the support platform is mounted. Compared to existing dust covers, the dust cover in the above solution can always cover the slide rail and will not expose the slide rail as the support platform moves, thus providing better dust protection.

[0004] The problem with the above technical solution is that: when piercing seamless tubes, piercing machines are used. During the operation of the piercing machine, the seamless tube is fixed on its clamping structure. However, most clamping structures are located below the piercing head, which poses a certain risk. In addition, most piercing machines require manual clamping and fixing of the workpiece, which reduces piercing efficiency. Summary of the Invention

[0015] Preferably, a method for operating a piercing machine for seamless tubes made of lightweight metal alloys includes the following steps:

[0016] S1.

[0017] S2. The support plate can be adjusted by adjusting the support components. When the support plate is adjusted to an inclined state, it is convenient for the staff to feed the seamless tube.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention uses a single-axis motor to drive the positive and negative lead screws to rotate. Combined with a clamping and fixing assembly, the seamless tube and side limiting plate can be fixed within the limiting groove. The support assembly can be adjusted to adjust the bearing plate. When the bearing plate is adjusted to an inclined state, it facilitates the loading of the seamless tube by the operator.

[0022] 2. This invention uses a dual-axis motor to drive a rotating shaft. The drive gears at both ends of the shaft are connected to the gear plate through meshing, which drives the mounting bracket to move along the slide rail. As the shaft rotates, an upper transmission rod is fixedly connected to both ends of the shaft. The upper transmission rod is connected to a support rod through a first connecting rod, and the other end of the support rod is rotatably mounted on the bearing plate. This pushes the bearing plate outward. A limit rod is rotatably mounted on one side of the bearing plate, which provides balance support for the bearing plate. This allows the bearing plate to tilt and move outward, and when it is retracted, it can be made vertical. During the movement, the mounting bracket can also be moved into the outer shell of the device to achieve a folding and telescopic effect. During the piercing process, the coolant delivery device can be activated by adjusting the support assembly and the linkage plate. The coolant delivery device can then spray the coolant in the water tank through the interface, the fixing ring, and the water injection ring, and then spray it from the spray nozzle into the water injection ring, thereby cooling the seamless tube during the piercing process.

[0043] S2. The support plate 9 can be adjusted by adjusting the support component 7. When the support plate 9 is adjusted to an inclined state, it is convenient for the staff to feed the seamless tube. The support plate 9 can also be adjusted to a vertical state, which makes it easier to perform piercing processing on the seamless tube.

[0044] S3. When the adjustment support component 7 is activated, it can be retracted into the device housing 1, and the bearing plate 9 can fix the seamless tube to move below the piercing machine 4, automatically feeding the seamless tube and improving the efficiency of piercing the seamless tube.

[0045] S4. During the piercing process, the coolant delivery device 123 can be activated by adjusting the support component 7 and the linkage plate 117.

[0046] Working principle of the invention:

[0047] In use, the dual-axis motor 706 drives the rotating shaft 707 to rotate. The drive gears 707 at both ends of the rotating shaft 707 are connected to the gear plate 701 through meshing, which drives the mounting bracket 6 to move along the slide rail 702. When the rotating shaft 707 rotates, the upper transmission rod 711 is fixedly connected to both ends of the rotating shaft 707. The upper transmission rod 711 is connected to the support rod 712 through the first connecting rod 713. The other end of the support rod 712 is rotatably mounted on the bearing plate 9, which can push the bearing plate 9 to move outward. A limit rod 714 is rotatably mounted on one side of the bearing plate 9.

Then, the single-axis motor 105 drives the positive lead screw 106 and the negative lead screw 107 to rotate. Since the threads of the positive lead screw 106 and the negative lead screw 107 are set oppositely, the lifting sleeve 109 can be moved to both sides along the positive lead screw 106 and the negative lead screw 107, which can shorten the distance between the upper balance rod 114 and the lower balance rod 111, thereby driving the second connecting rod 112 on both sides to move to both sides, thereby clamping and fixing the seamless tube in the limiting groove 103 with the side limiting plate 104, achieving the effect of assisting the seamless tube to be pierced and improving the stability of the piercing.
