Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electrically fused pipe fitting production and processing, and more particularly to a novel electrically fused pipe fitting automatic production equipment. BACKGROUND

[0002] Electrically fused pipe fittings are widely used in gas delivery, water supply, sewage, agricultural irrigation, oil fields, mines, chemical industry, and postal and telecommunication fields, and are particularly used in pressure pipeline system fields such as gas delivery, water supply, oil fields, mines, and chemical industry, and have high requirements for environmental adaptability, pressure resistance, and safety performance. Generally, electrically fused pipe fittings are connected by an electrically fused welding machine at two connection posts of the electrically fused pipe fitting, and an embedded resistance wire in the inner wall of the electrically fused pipe fitting is powered to heat, and the heating energy is used to melt the pipe fitting and pipe material at the position matched with the resistance wire, so that the molten materials in the melting zone are intertwined and naturally cooled to form a reliable connection.

[0003] The existing scheme of embedding a resistance wire in the inner wall of an electrically fused pipe fitting mainly uses an ordinary horizontal numerical control lathe, configures a special tool bar and tool, and manually assists operation to complete processing. The main operation process is as follows: the electrically fused pipe fitting is manually installed on the numerical control lathe, turning and spiral embedding of the resistance wire are completed by the numerical control lathe, and then manual assistance is used to complete the processing procedures such as chip removal, wire threading, wire hooking, and wire breaking. The connection post of the electrically fused pipe fitting needs to be manually installed after the pipe fitting is taken off from the lathe, and then a resistance, current, and voltage comprehensive measuring instrument is connected to the two connection posts of the electrically fused pipe fitting by manual operation. Whether the resistance, current, and voltage are within the standard value range is observed, and if they are within the standard value range, the product is considered to be qualified, and if they are not within the standard value range, the product is considered to be unqualified. Finally, the connection post protective cover is manually installed, and the product is packaged.

[0051] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0052] It is to be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or indirectly on the other element, with one or more intervening elements. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or indirectly connected or coupled to the other element, with one or more intervening elements.

[0053] It is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like, specify relative positions or orientations of an apparatus or element as shown in the drawings, and are used only for the purpose of ease of description and simplification of description, and do not indicate or imply that the indicated apparatus or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed or implied as limiting the application.

[0054] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or a quantity of the indicated elements. Thus, a feature with a "first", "second" or "third" designation can include one or more of the features implicitly or explicitly.

[0055] Please refer to Figures 1-18 , now the new automatic production equipment for electric melting pipe fittings provided by the embodiments of the present application will be described.

[0056] As Figures 1-5As shown, the new automatic production equipment for electrically fused pipe fittings includes an equipment base frame 100, a conveying mechanism 200, an electrically fused pipe fitting sequencing and positioning mechanism 300, an electrically fused pipe fitting comprehensive processing mechanism 400, a terminal post installation mechanism 500, a terminal post detection mechanism 600, a terminal post protective cover installation mechanism 700, and a control center 1000. The equipment base frame 100 serves as the basic frame of the equipment and supports all mechanisms and structures of the equipment. The conveying mechanism 200 is used to convey the electrically fused pipe fittings to be processed. The conveying mechanism 200 is provided with an electrically fused pipe fitting posture correction mechanism. After the electrically fused pipe fittings are positioned in a unique posture, they enter the sequencing process. The electrically fused pipe fitting sequencing and positioning mechanism 300 formally sequences the electrically fused pipe fittings and enters the processing procedure. The electrically fused pipe fitting comprehensive processing mechanism 400 enters the electrically fused pipe fittings into the turning, chip removal, wire threading, wire embedding, and wire breaking processing procedures. The terminal post installation mechanism 500 is used to install the terminal posts of the electrically fused pipe fittings. The terminal post detection mechanism 600 is used to detect whether the terminal posts of the electrically fused pipe fittings are in good contact with the resistance wire after the installation of the terminal posts of the electrically fused pipe fittings is completed. The terminal post protective cover installation mechanism 700 is used to install the terminal post protective cover on the outer cylinder of the terminal post of the electrically fused pipe fittings that have passed the installation and detection of the terminal posts. After the current sequencing process is completed, the equipment automatically outputs the processed electrically fused pipe fittings as qualified products from the qualified product outlet 109 of the equipment for packaging. The control center 1000 is used to control the work of the entire equipment. All the above processing procedures are automatically completed under the control of the control center 1000.

[0057] The following describes the processing steps of this new type of automated production equipment for electrofusion fittings. First, a robot or loading rack places the pre-made electrofusion fitting semi-finished product onto the conveyor belt of the conveying mechanism 200. The conveyor belt is equipped with product conveying guide rails 202, posture adjustment rails 203, limit rails 206, and cylindrical limit strips 204 on the outer wall of the terminal block to correct and unify the posture of the electrofusion fitting, ensuring that the outer cylindrical wall of the terminal block and the through hole 523 of the terminal block are vertically upwards. The conveyor belt continues to transport the electrofusion fitting semi-finished product to the sorting and horizontal positioning mechanism 304. After the electronic sensor detects the electrofusion fitting semi-finished product, the sorting and vertical flipping mechanism 303 flips the electrofusion fitting semi-finished product 90° to stand it vertically. Next, the sorting and horizontal movement... Mechanism 302 drags the sorting vertical positioning moving mechanism 301 to the right until the first inner support block 331 and the second inner support block 332 of the transverse bidirectional sliding cylinder 330 can extend into the inner hole of the electrofusion tube semi-finished product. The second straight cylinder 325 of the sorting vertical positioning moving mechanism 301 then operates. Driven by the cylinder rod, the transverse bidirectional sliding cylinder 330 slides vertically downwards, and the first inner support block 331 and the second inner support block 332 extend into the inner hole of the electrofusion tube semi-finished product. Under the action of the transverse bidirectional sliding cylinder 330, the first inner support block 331 and the second inner support block 332 open up and support the inner wall of the electrofusion tube semi-finished product, gripping the electrofusion tube. Next, pulled by the cylinder rod, the transverse bidirectional sliding cylinder 330 moves vertically upwards. Further, the sorting horizontal moving mechanism 30... 2. Driven by the first straight cylinder 319, the mechanism moves from right to left to a position vertically above the first processing sorting and positioning station 335. Next, the sorting vertical positioning moving mechanism 301 pushes the transverse bidirectional sliding cylinder 330 to slide vertically downward, positioning the electrofused pipe fitting semi-finished product on the first processing sorting and positioning station 335. After the electronic sensor detects the electrofused pipe fitting semi-finished product, the first inner support block 331 and the second inner support block 332 of the first gripping mechanism 800 of the transverse bidirectional sliding cylinder 330 slide inward, releasing the electrofused pipe fitting semi-finished product. Next, the second straight cylinder 325 pulls the vertical motion guide rail slider 322 to slide upward, and the sorting vertical positioning moving mechanism 301 and the sorting horizontal moving mechanism 302 are linked to reset, entering the next cycle of waiting state. Furthermore, the second gripping mechanism 900 moves to the position in front of the electrofusion tube semi-finished product positioned at the first processing sorting and positioning station 335, opens the third cylinder gripper 918 and the fourth cylinder gripper 919, and then moves forward to grip the electrofusion tube semi-finished product, removes the electrofusion tube semi-finished product, and then moves it to place it on the spindle end clamp 422. The third cylinder gripper 918 and the fourth cylinder gripper 919 of the second gripping mechanism 900 release the electrofusion tube semi-finished product and return to the initial position, waiting for the next cycle. Next, the electrofusion tube clamping cylinder 415 pulls the upper clamp bearing seat 423 down, and the upper end clamp 424 of the spindle moves down accordingly, thereby positioning and fixing the upper end of the electrofusion tube semi-finished product. Furthermore, the spindle servo motor synchronous pulley 434 starts.The new type of electrically fused pipe fitting machining device on the electrically fused pipe fitting comprehensive machining mechanism 400 further slides to the designated position, and starts the turning, chip removal, threading, embedding, and breaking of the electrically fused pipe fitting, completes the threading, embedding, and breaking of the electrically fused pipe fitting, and then the main shaft servo motor 430 stops, the rotating main shaft 438 stops rotating, the electrically fused pipe fitting clamping cylinder 415 pushes the upper end clamp bearing seat 423 to move up to the initial position to release the electrically fused pipe fitting semi-finished product, and the upper end clamp bearing seat 423 waits for the next cycle. Further, the second grabbing mechanism 900 grabs the electrically fused pipe fitting semi-finished product with the embedded resistance wire and moves to the left until it moves to the electrically fused pipe positioning ring 503 of the terminal post installation mechanism 500, places the electrically fused pipe fitting on the electrically fused pipe positioning ring 503, and releases the electrically fused pipe fitting. Further, the terminal post punch 512 punches the terminal post into the terminal post through hole 523 of the electrically fused pipe fitting, and embeds the terminal post.
