Description

Technical Field

[0001] This invention relates to the field of riveting equipment technology, and more specifically to a riveting equipment for pipe production. Background Technology

[0002] Riveting equipment is a commonly used processing equipment in the pipeline production and processing. It is mainly used to rivet and fix the connectors at the ends of the pipeline to the pipeline body, so as to achieve a stable connection between the pipeline and the joint.

[0003] Existing riveting equipment typically requires manual placement of each pipe at the riveting station during pipe processing. The pipes are then manually positioned before the riveting mechanism is activated to complete the process. After processing, the finished product is manually removed. This process is not only inefficient and labor-intensive, but also prone to errors due to manual positioning, leading to misalignment of the riveting position and affecting the accuracy and quality of the finished product. For batch pipe processing, manual loading and unloading slows down the overall processing progress, making it difficult to meet the demands of large-scale production. Therefore, we propose a pipe production riveting equipment to address the problems existing in the current technology. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a riveting device for pipe production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a riveting device for pipe production, including a feeding hopper and a riveting mechanism. A conveying mechanism is arranged below the feeding hopper, and a positioning seat for fixing the pipe is also arranged below the feeding hopper in cooperation with the conveying mechanism. The conveying mechanism includes a first conveying seat and a second conveying seat, both of which have grooves at their adjacent ends. A transmission rod is fixedly connected to the first conveying seat, and the transmission rod and the second conveying seat are elastically connected. An electric push rod is arranged outside the first conveying seat, and the telescopic end of the electric push rod is fixedly connected to the first conveying seat. A limiting mechanism for positioning the pipe is installed on the positioning seat, and a push rod is connected to the limiting mechanism. The push rod cooperates with the second conveying seat for unloading.

[0006] It also includes a hopper with an inclined surface, baffles on both sides of the inclined surface, and a discharge port at the bottom of the inclined surface.

[0007] It also includes a connecting frame that is fixedly connected between the output end of the electric push rod and the first conveying seat, a magnetic strip that is installed inside the first conveying seat, the magnetic strip being magnetically connected to the second conveying seat, and a square opening that mates with the first conveying seat on the positioning seat.

[0008] It also includes a slot on the side wall of the second conveyor seat, in which the transmission rod is slidably connected, and a spring connected to the transmission rod is connected in the slot.

[0009] It also includes a first electric telescopic rod installed on the positioning seat, and the limiting mechanism includes a mounting frame and a limiting seat. Both the mounting frame and the limiting seat are located above the positioning seat, and push rods are fixedly connected to both the mounting frame and the limiting seat.

[0010] It also includes that the mounting frame and the limiting seat are fixedly connected by a connecting plate, the telescopic end of the first electric telescopic rod is fixedly connected to the connecting plate, the internal width of the mounting frame matches the pipe, and a connecting rod is fixedly connected to the second conveying seat, the connecting rod and the push rod cooperate.

[0011] It also includes a groove on the positioning seat that matches the second conveying seat, the groove being used to fix the pipe.

[0012] It also includes a base located below the hopper, with the first and second conveying seats slidably connected to the base, the positioning seat fixedly connected to the base, and a gap between the positioning seat and the base for the transmission rod to pass through.

[0013] It also includes a riveting mechanism comprising a mounting cylinder, a limiting cylinder fixedly connected inside the mounting cylinder, a plurality of riveting blocks that cooperate with the limiting cylinder being slidably connected inside the limiting cylinder, and a positioning cylinder being slidably connected inside the mounting cylinder, the positioning cylinder cooperating with the riveting blocks.

[0014] It also includes a second electric telescopic rod installed on the mounting cylinder, the telescopic end of the second electric telescopic rod being fixedly connected to the positioning cylinder, and the positioning cylinder having a feed port.

[0015] The technical solution provided by this invention has the following advantages compared with the prior art: This invention, through the coordinated arrangement of a feeding hopper, a conveying mechanism, and a positioning seat, enables continuous feeding and riveting of pipes. Compared to the traditional manual method of feeding and positioning each pipe individually, this method offers higher processing efficiency and effectively reduces labor intensity. The elastic connection between the first and second conveying seats in the conveying mechanism allows for gradual adjustment of the pipe position during transport to the positioning seat. Combined with a limiting mechanism, this ensures precise positioning, guaranteeing stable pipe position during riveting and preventing issues such as riveting deviation or pipe loosening. This significantly improves the finished product qualification rate of the riveting process. Simultaneously, the limiting mechanism can also drive the second conveying seat to move, thus completing the unloading function without the need for an additional unloading component. Most existing pipe riveting equipment requires manual assistance to adjust the pipe position, making it difficult to adapt to pipe riveting of different lengths and specifications, and has a low degree of automation. However, this equipment, through the linkage design of the conveying mechanism and the limiting mechanism, can automatically complete the entire process of feeding, positioning, and unloading, making it more adaptable to pipes of different lengths and more flexible in use.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Example 1: Please see Figures 1-8 The present invention provides a technical solution: a riveting device for pipe production, including a feeding hopper 1 and a riveting mechanism 7. A conveying mechanism 3 is provided below the feeding hopper 1, and a positioning seat 8 for fixing the pipe is also provided below the feeding hopper 1 in cooperation with the conveying mechanism 3. The conveying mechanism 3 includes a first conveying seat 33 and a second conveying seat 34. The ends of the first conveying seat 33 and the second conveying seat 34 that are close to each other are provided with grooves 35. A transmission rod 301 is fixedly connected to the first conveying seat 33. The transmission rod 301 and the second conveying seat 34 are elastically connected. An electric push rod 31 is provided on the outside of the first conveying seat 33. The telescopic end of the electric push rod 31 is fixedly connected to the first conveying seat 33.

[0022] In specific implementation: the feeding hopper 1 is used for feeding, and the pipeline is transported to the positioning seat 8 by the conveying mechanism 3. The grooves 35 opened on the first conveying seat 33 and the second conveying seat 34 are used to store the pipeline. Since the first conveying seat 33 and the second conveying seat 34 are elastically connected by the transmission rod 301, when the first conveying seat 33 passes the positioning seat 8, the second conveying seat 34 and the positioning seat 8 cooperate to position the pipeline. Then, the pipeline is riveted by the riveting mechanism 7. At this time, the surface of the second conveying seat 34 slides in contact with the bottom of the feeding hopper 1, thereby blocking the pipeline in the feeding hopper 1 and preventing it from being discharged.

[0023] Please see Figure 2 The present invention provides a technical solution: the feeding hopper 1 includes an inclined surface 101, baffles are provided on both sides of the inclined surface 101, and a discharge port 102 is provided at the bottom of the inclined surface 101.

[0024] In practice: the inclined plane 101 transports the pipe by its own weight through the outlet 102 to the groove 35 on the first conveying seat 33 and the second conveying seat 34, and then the pipe is transported to the positioning seat 8 by the conveying mechanism 3.

[0025] Please see Figures 3-5The present invention provides a technical solution: a slot is provided on the side wall of the second conveying seat 34, the transmission rod 301 is slidably connected in the slot, and a spring 302 connected to the transmission rod 301 is connected in the slot.

[0026] In practice: the slot and spring 302 are used to elastically connect the first conveyor seat 33 and the second conveyor seat 34.

[0027] Please see Figures 4-5 The present invention provides a technical solution: a connecting frame 32 is fixedly connected between the output end of the electric push rod 31 and the first conveying seat 33, a magnetic strip 6 is installed in the first conveying seat 33, the magnetic strip 6 is magnetically connected to the second conveying seat 34, and a square opening 801 that cooperates with the first conveying seat 33 is provided on the positioning seat 8.

[0028] In specific implementation: The magnetic strip 6 is used to magnetically connect the first conveyor seat 33 and the second conveyor seat 34. At the same time, it works with the transmission rod 301 and the spring 302 to connect the first conveyor seat 33 and the second conveyor seat 34 together. When the first conveyor seat 33 passes the positioning seat 8, the second conveyor seat 34 is blocked by the positioning seat 8. At this time, the pipe is fixed on the second conveyor seat 34 and the positioning seat 8. If the first conveyor seat 33 continues to move, a gap is created between the first conveyor seat 33 and the second conveyor seat 34. At this time, the pipe can be riveted.

[0029] Second embodiment: Please see Figures 5-6 Based on Embodiment 1: A limiting mechanism 5 for positioning the pipeline is installed on the positioning seat 8. A push rod 53 is connected to the limiting mechanism 5. The push rod 53 cooperates with the second conveying seat 34 for unloading. A first electric telescopic rod 4 is installed on the positioning seat 8. The limiting mechanism 5 includes a mounting frame 52 and a limiting seat 54. Both the mounting frame 52 and the limiting seat 54 are located above the positioning seat 8, and push rods 53 are fixedly connected to both the mounting frame 52 and the limiting seat 54.

[0030] In specific implementation: After the pipe is fixed between the second conveying seat 34 and the positioning seat 8, the limiting mechanism 5 limits one end of the pipe to prevent the pipe from moving when riveting the other end, which would cause the riveting position to deviate. After the riveting is completed, the push rod 53 drives the connecting rod 55 on the second conveying seat 34 to move the second conveying seat 34. At this time, a gap is created between the second conveying seat 34 and the positioning seat 8 for the pipe to pass through after riveting.

[0031] Please see Figures 5-6The present invention provides a technical solution: the mounting frame 52 and the limiting seat 54 are fixedly connected by the connecting plate 51, the telescopic end of the first electric telescopic rod 4 is fixedly connected to the connecting plate 51, the internal width of the mounting frame 52 matches the pipe, and a connecting rod 55 is fixedly connected to the second conveying seat 34, and the connecting rod 55 cooperates with the push rod 53.

[0032] In specific implementation: The first electric telescopic rod 4 drives the installation frame 52 and the limiting seat 54 to move. The end of the installation frame 52 near the pipe is tapered, which facilitates the pipe entering the installation frame 52. After the pipe enters the straight part of the installation frame 52, the pipe is limited. Then, the riveting mechanism 7 rivets the pipe. After the riveting is completed, the first electric telescopic rod 4 drives the installation frame 52 to move above the positioning seat 8. The push rod 53 on the installation frame 52 and the limiting seat 54 moves synchronously, thereby pushing the connecting rod 55 to move. The second conveying seat 34, which is fixedly connected to the connecting rod 55, moves synchronously, thereby creating a gap between the second conveying seat 34 and the positioning seat 8, allowing the pipe to be discharged. After discharge, the electric push rod 31 is activated to push the first conveying seat 33, thereby moving the first conveying seat 33 and the second conveying seat 34 to their original positions.

[0033] Please see Figure 5 The present invention provides a technical solution: the positioning seat 8 is provided with a matching groove 35 on the second conveying seat 34, and the groove 35 is used to fix the pipe.

[0034] In specific implementation: The groove 35 opened on the positioning seat 8 and the second conveying seat 34 is used to position the pipeline. The top of the positioning seat 8 is provided with a conical surface and a flat surface. The conical surface facilitates the pipeline to enter the positioning seat 8, and the flat surface is used to limit the pipeline.

[0035] Please see Figures 2-3 The present invention provides a technical solution: a base 2 is provided below the feeding hopper 1, the first conveying seat 33 and the second conveying seat 34 are slidably connected to the base 2, the positioning seat 8 is fixedly connected to the base 2, and a gap is provided between the positioning seat 8 and the base 2 for the transmission rod 301 to pass through.

[0036] Please see Figures 7-8 The present invention provides a technical solution: the riveting mechanism 7 includes an installation cylinder 71, a limiting cylinder 73 is fixedly connected inside the installation cylinder 71, a plurality of riveting blocks 74 that cooperate with the limiting cylinder 73 are slidably connected inside the limiting cylinder 73, and a positioning cylinder 72 is slidably connected inside the installation cylinder 71, the positioning cylinder 72 and the riveting blocks 74 cooperate.

[0037] In specific implementation: the riveting mechanism 7 is used to rivet the port of the pipe. The two ends of the riveting block 74 are conical and cooperate with the inner walls of the limiting cylinder 73 and the positioning cylinder 72, respectively.

[0038] Please see Figures 7-8 The present invention provides a technical solution: a second electric telescopic rod 76 is installed on the mounting cylinder 71, the telescopic end of the second electric telescopic rod 76 is fixedly connected to the positioning cylinder 72, and the positioning cylinder 72 is provided with a feed port 75.

[0039] In practice: the feed inlet 75, in conjunction with the external feeding mechanism, can automatically complete the entry of the plastic parts. After the plastic parts enter, the entire riveting mechanism 7 is moved to connect the pipe and the plastic parts. Then, the second electric telescopic rod 76 is activated to drive the positioning cylinder 72 to move. The positioning cylinder 72 further pushes the riveting block 74. Under the pressure of the positioning cylinder 72 and the limiting cylinder 73, multiple riveting blocks 74 move closer to each other, thereby riveting and fixing the plastic parts and the pipe.

[0040] Working principle: In use, the pipes to be riveted are placed in batches into the feeding hopper 1. The pipes fall one by one along the inclined surface 101 through the discharge port 102 into the corresponding grooves 35 of the first conveyor seat 33 and the second conveyor seat 34. The electric push rod 31 is activated to drive the first conveyor seat 33 to move along the base 2 towards the positioning seat 8. At this time, the first conveyor seat 33 drives the second conveyor seat 34 to move synchronously under the traction of the magnetic strip 6 and the spring 302. When the entire pipe is transported to the positioning seat 8, the first conveyor seat 33 first passes through the square opening 801 on the positioning seat 8. The second conveyor seat 34 is blocked by the side of the positioning seat 8 and stops on one side of the positioning seat 8. The pipe falls into the groove 35 of the positioning seat 8. At this time, the first conveyor seat 33 continues to move, gradually increasing the distance between itself and the second conveyor seat 34. The spring 302 is stretched and the magnetic strip 6 gradually disengages, completing the pipe transportation and positioning, avoiding multiple pipes from entering the processing position at the same time, and ensuring continuous processing of a single pipe. After the pipe falls into the positioning seat 8, the first electric telescopic rod 4 is activated to drive the connecting plate 51 to move down. The connecting plate 51 drives the mounting frame 52 and the limiting seat 54 to move down synchronously. The mounting frame 52 covers the end of the pipe that extends out of the positioning seat 8, completing the correction and limiting of the pipe position. At this time, the other end of the pipe is aligned with the feed port 75 of the riveting mechanism 7. The external feeding mechanism feeds the workpiece to be riveted into the positioning cylinder 72 through the feed port 75. Then, the riveting mechanism 7 is driven to move as a whole towards the pipe, so that the end of the pipe is inserted into the workpiece to be riveted. After that, the second electric telescopic rod 76 is activated to push the positioning cylinder 72 to move along the mounting cylinder 71. The inner wall of the positioning cylinder 72 squeezes multiple riveting blocks 74. The multiple riveting blocks 74 are synchronously gathered towards the center under the limitation of the limiting cylinder 73, completing the riveting and fixing of the pipe end and the workpiece. After riveting is completed, the second electric telescopic rod 76 drives the positioning cylinder 72 to reset, the riveting block 74 loses its squeezing force and releases the riveted pipe, and then the first electric telescopic rod 4 drives the connecting plate 51 to reset upward. During this process, the push rod 53 on the connecting plate 51 moves upward. After the push rod 53 moves to contact the connecting rod 55 on the second conveying seat 34, it pushes the second conveying seat 34 to move towards the first conveying seat 33. A feeding gap is formed between the second conveying seat 34 and the groove 35 of the positioning seat 8. The riveted pipe falls along the gap to complete the automatic unloading. Then the first electric telescopic rod 4 resets to the initial position, the electric push rod 31 pulls the first conveying seat 33 and the second conveying seat 34 to reset, the magnetic strip 6 re-attaches the second conveying seat 34, the spring 302 resets, and it is ready for the next feeding process. This cycle can realize the continuous automated riveting process of the pipe.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
