[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0022] refer to Figures 1 to 4 The utility model is an automatic production line for small tunnel conduits, which includes a tapered heater 1, a cutting head 2, a frame 3, a servo chuck 4, a control system 5, a feeding device 6, a conveying device 7, a telescopic cylinder 8, a rack guide 9, a cutting head servo moving motor 10, a hole opening lateral swing motor 11, a hole opening gun head 12, an upper and lower conveying system 13 and a loading rack 14.

[0023] The product size is 14000mm×1200mm×1610mm, and the length of the processed raw material is ≤8500mm. The small tube (indefinite length) passes through the loading rack and is detected by the laser detection switch. The control system controls the loading cylinder to work and send the small tube to the upper conveying system.

[0024] The upper conveying platform transports the small tube to the electric adjustable servo chuck. After the photoelectric sensing inside the chuck detects the material, the chuck starts to clamp and the conveying system stops working.

[0025] The servo plasma cutting machine head starts to move toward the tapering machine, and the actual length of the small tube is measured by the laser detection switch and the meter coding wheel. The three plasma cutting guns are started and move with the cutting head. At the same time, the electric adjustable servo chuck rotates to complete the small tube opening and excess material cutting.

[0026] The electric chuck is released, and the upper conveying system moves the small tube with the hole in the reverse direction to the starting position. The telescopic cylinder drives the semi-groove wheel to retract, and the finished small tube and the remaining material fall freely to the lower conveying system.

[0027] After the laser detection switch of the lower conveying system detects the material, it starts to convey the material toward the tip shrinking machine. After the induction switch of the tip shrinking machine works, a stop command is issued, the conveying system stops working, the clamping cylinder of the tip shrinking machine works, and the feeding cylinder works. After the sensor is heated, the tip shrinking is completed, the feeding cylinder returns the material, the clamping is released, and the conveying system conveys it in the opposite direction to the appropriate position. Some of the telescopic cylinders drive the semi-grooved wheels to shrink, and the small tube finished product 1 falls to the finished product area. The instruction repeats the above actions, all the telescopic cylinders drive the groove wheels to shrink, the small tube finished product 2 falls to the finished product area, and the remaining materials fall to the remaining material area.

[0028] The working process is completed and the next cycle starts automatically.

[0029] The electric adjustable servo chuck is composed of an electric chuck, a servo lifting motor, and a servo rotating motor. The clamping torque of the electric chuck can be adjusted by the torque regulator in the range of 7KN-25KN. The clamping force can meet the requirements of no slipping during rotation and safe clamping. The lifting is composed of a servo motor and a screw lifting mechanism with an accuracy of 0.01mm. The electric adjustable servo chuck is located on the right side of the equipment, providing the functions of clamping and rotating the small catheter. The entire chuck box is fixed to the frame by bolts.

[0030] The servo plasma cutting machine head is composed of a plasma generator, three plasma cutting guns, a lateral swing motor, a laser detection switch, a mobile servo motor + reducer, a guide rail fixing device, and a guide rail gear. The air pipe, wires, and induction wires connected to the plasma generator and the machine head are installed in the drag chain and move with the drag chain. The lateral swing motor is used for lateral movement when opening holes. The shaft end of the device is connected to a T-type screw rod, and the other end of the screw rod is fixed to the cutting head. The cutting head itself has two guide cabinet fixing devices, which are fixed on the guide rail of the frame with a small friction coefficient. The power unit is composed of a mobile servo motor + reducer and a guide rail gear. When the motor rotates, the guide rail gear rotates and rolls with the guide rack on the frame to achieve precise positioning. The machine head is installed above the frame and connected to the frame through a guide rail fixing device.

[0031] The upper and lower conveying system is composed of a motor + reducer, a sprocket group, a chain group, a telescopic cylinder and a semi-grooved wheel group to realize the conveying and falling of materials. The shaft end of the sprocket group is connected and fixed with a semi-grooved wheel, and the shaft end of the telescopic cylinder is connected with a semi-grooved wheel through a bearing, which allows the semi-grooved wheel to rotate freely. During operation, the telescopic cylinder is pressed tightly, and the semi-grooved wheel at the cylinder end and the semi-grooved wheel at the sprocket end fit together to form a groove structure with a semicircular cross-section, which can just lift the small catheter. Due to the existence of pressure, when the sprocket rotates, the torque is less than the static friction between the two wheels, so the two wheels rotate synchronously to complete the material conveying. After the conveying is completed, the telescopic cylinder shrinks and the material falls. The power source of the upper and lower conveying system is connected to the fixed plate of the frame by bolts, and the sprocket is connected to the frame by bolts through the shaft and the bearing seat. The cylinder is FA type and is connected to the frame by bolts.

[0032] The tipping machine and heater are located inside the system, and there are also original related patents. The working principle is not described here. The tipping machine and the lower track groove are at the same elevation in the Y-axis direction. The front end of the frame is 200mm away from the frame and is fixed to the ground with anchor bolts. At the same time, the tipping mold is coaxial with the lower track groove.

[0033] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "width", "horizontal", "top", "bottom", "inside", "outside" and other terms indicating orientation or position relationship are based on the orientation or position relationship shown in the drawings of this specification, which are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in a specific orientation. Therefore, the above-mentioned orientation or position relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.

[0034] In addition, in the description of this specification, “plurality” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
