Technical Field

Background Art

[0002] In mechanical manufacturing and process flow, pipe processing is a key link; for pipe processing, fast and accurate length feeding plays a vital role in work efficiency and quality.

[0003] The pipe length feeding process is to feed pipes of specified length to the automated cutting equipment so that the automated cutting equipment can cut the pipes, thereby obtaining multiple pipes of the same length for the subsequent manufacture of forgings or metal pressings. The current pipe length feeding process usually uses manual measurement of the pipes, marks the positions where cutting is required, and then manually controls the conveyor line to transport the pipes to the automated cutting equipment for cutting.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0128] Embodiment 1:

[0130] The pipe conveying line 2 is used to convey the pipe 1 from the loading position to the automated cutting equipment;

[0131] The pressing device 3 is used to press the pipe 1 onto the pipe conveying line 2, so that the pipe 1 stops on the pipe conveying line 2;

[0132] The equipment conveying line 4 is connected to the clamping device 3 , and the clamping device 3 is used to move on the equipment conveying line 4 ; wherein the equipment conveying line 4 is parallel to the pipe conveying line 2 .

[0133] In this example, a pipeline conveyor line is provided for conveying pipe fittings 1, and an equipment conveyor line 4 is provided for moving the clamping device 3 to a required designated position; when the pipe conveyor line 2 conveys the pipe fittings 1 to the automated cutting equipment to a preset delivery length, the clamping device 3 is provided to clamp the pipe fittings 1 on the pipe conveyor line 2, and then the automated cutting equipment cuts the pipe fittings 1, and then the clamping device 3 is detached from the pipe fittings 1, and then the pipe conveyor line 2 conveys the pipe fittings 1 to the automated cutting equipment to deliver the delivered length of the pipe fittings 1, and this cycle is repeated, thereby achieving continuous, stable and efficient delivery processing of the pipe fittings 1 for the automated cutting equipment, ensuring that the length of each cut pipe fitting 1 is consistent with the delivery length, thereby improving the cutting efficiency and accuracy of the pipe fitting 1, and ensuring the product quality of the subsequent forgings or metal pressings.

[0134] In a preferred embodiment, the pipe conveying line 2 comprises: at least one pipe conveying roller 21;

[0135] At least one pipe conveying roller 21 is arranged in sequence along the horizontal direction.

[0136] In this example, by providing at least one pipe conveying roller 21 arranged in the horizontal direction, the technical effect of automatically conveying the pipe 1 to the automated cutting device is achieved. Preferably, the pipe conveying roller 21 is a motorized roller.

[0137] The electric roller is a new type of drive device that places the motor and reducer together inside the drum.

[0138] The electric drum has the motor and reducer built into the drum body, which greatly saves space and makes the overall structure more compact. Since the motor and reducer are directly connected, the intermediate transmission links are reduced and the transmission efficiency is improved. The electric drum generates low noise during operation, which is conducive to improving the working environment. The electric drum adopts high-quality materials and advanced manufacturing technology, which makes it have a long service life. The transmission system of the electric drum is stable and reliable, and it runs smoothly without vibration. The electric drum can work stably under various harsh environmental conditions, such as humid, muddy, and dusty environments. The electric drum has good internal sealing, which can effectively prevent dust and moisture from entering, ensuring the normal operation of internal components.

[0139] Specifically, the pipe conveying line 2 further includes: a pipe support frame 22;

[0140] One end of the pipe support frame 22 faces the loading position, and the other end of the pipe support frame 22 faces the automated cutting equipment;

[0141] At least one pipe 1 delivery pipe is located in the pipe support frame 22 and is arranged in sequence along the length direction of the pipe support frame 22 . The pipe 1 delivery pipe is rotatably connected to the pipe support frame 22 .

[0142] In this example, the pipe support frame 22 is used to position the pipe conveying roller 21 at a specified height.

[0143] Optionally, the pipe conveying roller 21 has a V-shaped groove 23 , and the V-shaped groove 23 is used to accommodate the pipe 1 .

[0144] Optionally, the pipeline conveying line further comprises: a conveying roller driving device, a first chain and a second chain;

[0145] The conveying roller driving device is meshedly connected with a pipe conveying roller 21 through a first chain;

[0146] At least one pipe conveying roller 21 is meshed and connected in sequence through a second chain;

[0147] The conveying roller driving device drives all the pipe conveying rollers 21 to rotate through the first chain and the second chain.

[0148] Optionally, the pipe support frame 22 includes: two pipe support plates 221, more than two pipe support columns 222 and at least one pipe base 223;

[0149] The two pipe support plates 221 are arranged in parallel, one end of the pipe support plate 221 faces the loading position, and the other end of the pipe support plate 221 faces the automated cutting equipment;

[0150] Both ends of the pipe conveying roller 21 are fixed to the upper side surfaces of the two pipe supporting plates 221 through a bearing assembly 24 respectively; the bearing assembly 24 includes a rolling bearing 241 and a clamp 242, the rolling bearing 241 is fixed to the clamp 242, and the clamp 242 is fixed to the upper side surfaces of the pipe supporting plates 221;

[0151] The top end of a pipe support column 222 is connected to the lower side of a pipe support plate 221;

[0152] The top end of a pipe base 223 is connected to the bottom ends of two pipe support columns 222 respectively.

[0153] In this example, the pipe support plate 221 and the pipe 1 support seat are provided to ensure that the pipe conveying roller 21 is positioned at a specified height and provide sufficient support force for the pipe 1 and the pipe conveying roller 21. The pipe base 223 is provided to ensure that the pipe conveying roller 21 and the pipe 1 can be firmly erected on the ground.

[0154] Further, the pipe base 223 includes: an upper base connection plate 2231, a lower base connection plate 2232, at least one base bolt 2233, an adjustment nut 2234 and at least one anchor bolt 2235;

[0155] The connecting plate 2231 on the base is connected to the bottom ends of the two pipe support columns 222;

[0156] The lower base connecting plate 2232 is located below the upper base connecting plate 2231;

[0157] One end of the base bolt 2233 is connected to the upper base connection plate 2231 through a thread, and the other end of the base bolt 2233 is connected to the lower base connection plate 2232 through a thread, and the adjustment nut 2234 is screwed onto the base bolt 2233;

[0158] The anchor bolt 2235 passes through the lower connection plate 2232 of the base and is inserted into the ground.

[0159] In this example, the distance between the upper base connecting plate 2231 and the lower base connecting plate 2232 is adjusted by providing a base bolt 2233 and an adjusting nut 2234, thereby adjusting the height of the pipe conveying roller 21 and the pipe 1 thereon, so as to realize the conveyance of pipes 1 of different diameters and models, thereby expanding the scope of application. The pipe base 223 is firmly fixed on the ground by providing an anchor bolt 2235, thereby ensuring the stability of the transportation of the pipe 1.

[0160] In a preferred embodiment, the pressing device 3 includes: a detection mechanism 31, a pipe pressing mechanism 32, a vertical moving mechanism 33 and a horizontal moving mechanism 34;

[0161] The detection mechanism 31 is connected to the pipe pressing mechanism 32 and the vertical moving mechanism 33 respectively. The detection mechanism 31 is used to detect the horizontal distance that the pipe 1 moves on the pipe conveying line 2. The detection mechanism 31 is also used to detect the vertical distance between the pipe pressing mechanism 32 and the top of the pipe 1.

[0162] The pipe pressing mechanism 32 is used to press the pipe 1 onto the pipe conveying line 2;

[0163] The vertical moving mechanism 33 is connected to the pipe pressing mechanism 32, and the vertical moving mechanism 33 is used to control the pipe pressing mechanism 32 to move in the vertical direction;

[0164] The horizontal moving mechanism 34 is connected to the vertical moving mechanism 33 , and the horizontal moving mechanism 34 is also movably connected to the equipment conveyor line 4 . The horizontal moving mechanism 34 is used to control the vertical moving mechanism 33 and the pipe pressing mechanism 32 to move in the horizontal direction.

[0165] In this example, the vertical distance is detected by the detection mechanism 31 to ensure that no matter what caliber and size of the pipe 1 is transported by the pipe conveying line 2, the vertical moving mechanism 33 can ensure that the pipe pressing mechanism 32 is at an appropriate height to ensure that the vertical moving mechanism 33 can accurately and firmly press the pipe 1 onto the pipe conveying line 2 to achieve the technical effect; wherein, the detection mechanism 31 controls the movement and stop of the vertical moving mechanism 33 according to the vertical distance, and the vertical distance at which the detection mechanism 31 controls the movement and stop of the vertical moving mechanism 33 can be set as needed.

[0166] The horizontal distance is detected by the detection mechanism 31, and the delivery distance of the pipe 1 is monitored. When the detection mechanism 31 detects that the horizontal distance reaches the preset delivery length, the detection mechanism 31 will instruct the pipe pressing mechanism 32 to press the pipe 1 onto the pipe conveyor line 2, so as to ensure that the pipe conveyor line 2 can output the pipe 1 of the specified delivery length to the automated cutting equipment every time, thereby ensuring the reliability and stability of the delivery operation for the automated cutting equipment.

[0167] In a preferred embodiment, the detection mechanism 31 includes: a proximity switch 311 and a sensor 312;

[0168] The proximity switch 311 is used to detect the vertical distance between the pipe pressing mechanism 32 and the top of the pipe fitting 1;

[0169] The proximity switch 311 is connected to the vertical moving mechanism 33. The proximity switch 311 is also used to send a vertical stop signal to the vertical moving mechanism 33. The vertical stop signal is used to instruct the vertical moving mechanism 33 to stop moving.

[0170] The sensor 312 is used to detect the horizontal distance that the pipe 1 moves on the pipe conveying line 2;

[0171] The sensor 312 is connected to the pipe pressing mechanism 32 , and the sensor 312 is also used to send a pipe pressing signal to the pipe pressing mechanism 32 , and the pipe pressing signal is used to instruct the pipe pressing mechanism 32 to press the pipe 1 onto the pipe conveying line 2 .

[0172] In this example, a detection distance is set in the proximity switch 311. When the proximity switch 311 moves to the detection distance from the top of the pipe 1, the proximity switch 311 will generate a vertical stop signal. The detection distance can ensure that the pipe pressing mechanism 32 presses the pipe 1 onto the pipe conveying line 2, while also ensuring that when the pipe pressing mechanism 32 is separated from the pipe 1, the pipe pressing mechanism 32 will not cause obstruction or friction to the transportation of the pipe 1.

[0173] A feeding distance is set in the sensor 312. When the sensor 312 detects that the horizontal distance moved by the pipe 1 on the pipe conveying line 2 reaches the feeding distance, the sensor 312 will send a pipe pressing signal to the pipe pressing mechanism 32. The pipe pressing signal is used to instruct the pipe pressing mechanism 32 to press the pipe 1 onto the pipe conveying line 2. At this time, the automatic cutting equipment will receive the pipe 1 with a length of the feeding distance and cut it, ensuring that the length of the pipe 1 cut by the automatic cutting equipment each time is consistent with the feeding distance.

[0174] In this embodiment, the proximity switch 311 is a position switch that can be operated without direct mechanical contact with the moving parts. When an object approaches the sensing surface of the switch 311 to the action distance, the switch can be actuated without mechanical contact or any pressure, thereby driving a DC appliance or providing control instructions to a computer (PLC) device. Exemplarily, the proximity switch 311 in this example is any one of a high-frequency oscillation proximity switch 311, a capacitive proximity switch 311, a Hall proximity switch 311, a photoelectric proximity switch 311, and an ultrasonic proximity switch 311.

[0175] High frequency oscillation type proximity switch 311: When a conductive object approaches the switch 311, eddy current is generated inside the object, thereby triggering the switch action. This type of switch has good anti-interference performance, high switching frequency, and can detect various metal objects.

[0176] Capacitive proximity switch 311: When an object moves toward the proximity switch 311, whether it is a conductor or not, the dielectric constant of the capacitor changes, thereby triggering the switch action. The detection object of this switch is not limited to conductors, and insulating liquids or powders can also be detected.

[0177] Hall proximity switch 311: A switch made of Hall elements. When a magnetic object moves close to the Hall switch, the Hall element produces the Hall effect, which changes the state of the switch's internal circuit, thereby triggering the switch. The detection object of this switch must be a magnetic object.

[0178] Photoelectric proximity switch 311: The light emitting device and the photoelectric device are installed in the same detection head in a certain direction. When a reflective surface (the object to be detected) approaches, the photoelectric device receives the reflected light and triggers the switch action. This switch can detect objects with reflective surfaces.

[0179] Ultrasonic proximity switch 311: A proximity switch 311 made using the Doppler effect principle. When an object approaches, the reflected signal received by the proximity switch 311 will produce a Doppler frequency shift, thereby triggering a switch action.

[0180] The sensor 312 is a device or apparatus that can sense (or respond to) a specified measured quantity and convert it into a usable signal output according to a certain rule. The sensor 312 is any one of an inductive sensor 312, a capacitive sensor 312, an electric contact sensor 312, a grating sensor 312, a laser sensor 312, and a solid array sensor 312.

[0181] Inductive sensor 312: Using the principle of electromagnetic induction, when the object being measured moves, the inductance of the coil changes, thereby measuring the length or displacement. Its resolution is very high, up to 0.01 micron, and the measurement range is generally less than 2 mm, and the largest can reach tens of mm.

[0182] Capacitive sensor 312: Using the principle of capacitance, when the object being measured moves, it causes a change in capacitance, thereby measuring length or displacement. The measuring range is large, such as the large-range capacitive sensor 312 for electronic calipers that appeared in the early 1980s, with a measuring range of 150 mm.

[0183] Electric contact sensor 312: It uses electric contact pairs to send out electric signals to determine whether the measured size is qualified or not. The movement of the electric contact can be directly transmitted by the measuring rod, or it can be amplified by levers or other mechanisms to increase its sensitivity. It is mainly used in automatic measurement.

[0184] Grating sensor 312: uses the moiré fringe phenomenon of the grating to measure length.
