Description

Technical Field

[0001] The present invention relates to the technical field of metal forming processing, and particularly relates to a forming device for processing special-shaped steel pipes. Background Art

[0002] Special-shaped steel pipes are long steel materials with a hollow cross-section. The cross-sectional shapes of special-shaped steel pipes are different from those of common round steel pipes. They have various different cross-sectional shapes, such as square, rectangular, oval, hexagonal, octagonal, etc. Special-shaped steel pipes are widely used in various fields such as structural components of automobiles, trains, airplanes, ships, and space launchers, mechanical parts, petrochemical industry, geological drilling, textile machinery, radio communication, medical and health, and military industry.

[0003] Special-shaped steel pipes are generally rolled from round steel pipes by a forming device. Different-shaped special-shaped steel pipes can use different rolling dies. When the round steel pipe is rolled by the forming device, the rolling die will extrude the round steel pipe, thereby extruding the round steel pipe into a specific shape. When there are unqualified special-shaped steel pipes in the formed special-shaped steel pipes, the detection device of the forming device can transmit the electrical signal of the unqualified one to the control center, and then the control center drives the switch of the marking pen to mark the unqualified special-shaped steel pipe.

[0004] However, when marking unqualified special-shaped steel pipes by the above method, some sensors or controllers are needed to cooperate to complete. This method has a high maintenance cost during use and is not conducive to the long-term use of the equipment. Summary of the Invention

[0005] In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a forming device for processing special-shaped steel pipes, which can mark unqualified special-shaped steel pipes during the forming process and can reduce the maintenance cost during the use of the equipment.

[0006] To achieve the above object, a forming device for processing special-shaped steel pipes is provided, which includes: an equipment platform, on which a rolling mill device and a detection device are arranged. There are multiple rolling mill devices, and the multiple rolling mill devices are arranged in a linear array. The detection device is located on one side of the multiple rolling mill devices; the detection device includes a fixed frame, a first detection block, a second detection block, a sliding plate, a driving component and a marking component. The bottom of the fixed frame is fixed on the equipment platform. The first detection block is fixed in the fixed frame. The second detection block and the sliding plate are both located in the fixed frame and are both slidably connected to the fixed frame up and down. The second detection block is located between the first detection block and the sliding plate, and the second detection block is slidably connected to the sliding plate. The sliding plate is connected to the driving component; the marking component includes a material storage box, a marking pen and a rotating rod. The material storage box is located at the top of the fixed frame, and the material storage box is communicated with the marking pen through a connecting pipe. A rotating seat is arranged on the top of the sliding plate, and the rotating rod is rotatably connected to the rotating seat. A top rod is arranged on the top of the second detection block, and the top of the top rod slidably penetrates through the middle of the sliding plate. One end of the rotating rod is rotatably connected to the top end of the top rod, and the other end of the rotating rod extends out of the fixed frame. The marking pen is vertically arranged outside the fixed frame, and the top end of the marking pen penetrates through the other end of the rotating rod; the marking pen includes an adjusting cylinder, a pen rod, a spring and a sponge block. The cross-section of the adjusting cylinder is inverted T-shaped, and the cross-section of the pen rod is I-shaped. The adjusting cylinder and the spring are both sleeved on the pen rod. The spring is located between the bottom of the adjusting cylinder and the bottom of the pen rod. The adjusting cylinder is detachably connected to the other end of the rotating rod. The sponge block is located at the bottom of the pen rod, and the sponge block is located on the side of the second detection block; the driving component can drive the sliding plate to move up and down along the fixed frame.

[0007] Working principle of the present invention: Ink is stored in the storage box. The ink can reach the sponge block through the connecting pipe and the pen barrel. Words can be engraved on the bottom of the sponge block. When the sponge block dips in the ink and covers the steel pipe, the words on the sponge block can be presented on the steel pipe. When the forming equipment works, the round steel pipe is rolled into a special-shaped steel pipe with a specific shape by the rolling device. After the special-shaped steel pipe is formed, it is detected by the detection device. The detection device can detect whether the special-shaped steel pipe is qualified or unqualified. When the detection device works, the driving component is started. The driving component drives the slide plate to move, so that the second detection block approaches the first detection block, and the shape formed by the first detection block and the second detection block is the shape of the special-shaped steel pipe. The special-shaped steel pipe passing through the rolling device passes through the first detection block and the second detection block. When the shape of the special-shaped steel pipe is unqualified, the first detection block or the second detection block cannot fit the surface of the special-shaped steel pipe, and the second detection block will move upward. When the second detection block moves upward, the ejector rod moves upward, driving one end of the rotating rod at the top of the ejector rod to move upward. The rotating rod rotates along the rotating seat, and the other end of the rotating rod and the marking pen connected thereto move downward, so that the sponge block at the bottom of the marking pen contacts the steel pipe, and the steel pipe can be further marked. When the sponge block contacts the steel pipe and the ejector rod continues to move upward, the other end of the rotating rod continues to move downward. The steel pipe squeezes the pen barrel upward through the sponge block, and the pen barrel moves upward relative to the adjusting cylinder, and the spring is compressed, so as to prevent the pen barrel from being broken by extrusion. When the steel pipe is qualified, the second detection block does not move and the marking pen does not work.

[0008] The beneficial effect of a forming device for processing special-shaped steel pipes in the present invention is as follows: By arranging components such as the ejector rod and the rotating rod on the second detection block, when the second detection block detects that the special-shaped steel pipe is unqualified, the ejector rod moves upward, driving one end of the rotating rod to move upward, so that the marking pen at the other end of the rotating rod moves downward and contacts the steel pipe, enabling the marking pen to mark on the steel pipe, thereby being able to mark the unqualified special-shaped steel pipes during the forming process. In this process, electronic devices such as sensors and controllers are not used, further reducing the maintenance cost during the use of the device.

[0009] According to the forming device for processing special-shaped steel pipes, a plurality of adjustment holes are provided on the outer side wall of the adjusting cylinder, and an adjustment bolt is threadedly provided at the end of the other end of the rotating rod, and the end of the adjustment bolt is located in one of the adjustment holes.

[0010] Rotate the adjustment bolt. When the end of the adjustment bolt moves away from the adjustment hole, the adjusting cylinder can move up and down along the other end of the rotating rod, and thus the distance between the bottom of the sponge block and the top of the steel pipe can be adjusted.

[0011] According to the forming equipment for processing special-shaped steel pipes, the driving assembly includes a driving screw, a synchronous pulley, a belt and a driving motor. Two driving screws and two synchronous pulleys are provided. Both ends of the two driving screws are rotatably connected to the fixed frame.

The tops of the two driving screws extend toward the top of the fixed frame and are fixedly passed through the synchronous pulleys. The belt is wound around the two synchronous pulleys, and the driving motor is drivingly connected to one of the driving screws.

[0012] When the driving assembly is working, the driving motor drives the driving screw connected to it to rotate. When one driving screw rotates, the other driving screw is driven to rotate through the synchronous pulley and the belt.
