Description

Technical Field

[0001] This utility model relates to the technical field of pipe forming equipment, specifically to an automatic pipe forming machine that turns over. Background Technology

[0002] In the manufacturing process of straight pipe fittings, it is usually necessary to perform corresponding forming processing on both ends of the fittings (such as grooves at the ends) to meet the requirements of subsequent assembly and use. Currently, the industry generally adopts the method of processing the ends of straight pipe fittings by using forming molds set on both sides of the worktable to complete the processing operations at both ends. Specifically, after one of the forming molds completes the processing of one end of the straight pipe fitting, the fitting needs to be removed from the mold and unloaded. Then, manually or with the help of other auxiliary equipment, the fitting is turned around so that the unprocessed end faces another forming mold. The turned fitting is then transferred to another forming mold for processing of the other end. The structure of the pipe fitting forming machine can refer to a pipe fitting forming machine disclosed in application number 2022109665541 and an automatic loading and unloading pipe fitting forming machine disclosed in application number 2023231595766 (it should be emphasized that the above prior art does not represent absolute prior art, but is only used to help illustrate the technical problem to be solved by this application and to emphasize the original intention of this application).

[0003] However, this processing method has obvious drawbacks: on the one hand, after the pipe fittings are processed at one end, they need to go through multiple additional steps such as unloading, turning around, and reloading, which takes a long time and seriously affects the overall production rhythm. Therefore, how to optimize the processing flow at both ends of straight pipe fittings, reduce unnecessary intermediate steps, and realize automated turning and transfer of the processing process to significantly improve production efficiency has become an urgent technical problem to be solved in the field of straight pipe fitting processing equipment. Utility Model Content

[0004] To address the shortcomings in the prior art, this utility model provides an automatic pipe forming machine with a reversible design.

[0005] The technical solution adopted by this utility model is: an automatic pipe forming machine, including a support, a worktable, a transfer mechanism and forming molds. There are two forming molds, which are respectively arranged on both sides of the worktable. A turning mechanism for rotating the pipe 90° to turn it around is provided between the two forming molds.

[0006] Furthermore, the turning mechanism includes a fixed base and a rotating cylinder gripper disposed on the fixed base.

[0007] Furthermore, the transfer mechanism is a truss robot, which is equipped with at least two robotic arms for gripping the pipe fittings.

[0008] Furthermore, it also includes a feeding mechanism, which includes a frame with a storage bin, a lifting assembly, a conveying mechanism, and a rotating and erecting mechanism; The lifting assembly is installed inside the storage bin and is used to push the straight pipe out of the storage bin to the conveying mechanism; The rotating upright mechanism is located at the end of the conveying mechanism. The rotating upright mechanism includes a rotating cylinder, a receiving base connected to the output end of the rotating cylinder, and a sleeve set on the receiving base. The sleeve can be fitted into the hole of the straight pipe.

[0009] Furthermore, the lifting assembly comprises at least two components, including an inclined push plate and a cylinder for driving the push plate to move up and down, wherein the top of the push plate has an inclined surface that slopes toward the conveying mechanism.

[0010] Furthermore, the conveying mechanism includes a support plate, a conveying motor, a conveyor belt, and long and short baffles located on both sides of the conveyor belt. The support plate is fixed on one side of the frame, the conveying motor and the conveyor belt are mounted on the support plate, and a material conveying channel is formed between the long and short baffles. The material conveying channel has an inlet on one side of the storage bin.

[0011] Furthermore, the receiving base includes a base plate connected to the output end of the rotary cylinder and a receiving plate connected to the base plate. The sleeve is vertically arranged on the receiving plate, and the receiving plate is set at 90° with the base plate.

[0012] The beneficial effects of this utility model are as follows: Compared with the traditional processing method where the pipe fitting needs to be unloaded and then reloaded after processing one end, this application allows the pipe fitting to be directly transferred to the turning mechanism after processing one end of the straight pipe in one forming mold. The turning mechanism then rotates the pipe 90 degrees, and the pipe fitting is then transferred to another forming mold for processing the other end. The entire process requires no manual intervention for unloading and reloading, reducing unnecessary intermediate steps and enabling continuous operation of processing both ends of the pipe fitting. This effectively shortens the overall processing cycle of a single pipe fitting and significantly improves the production cycle and the number of pipe fittings processed per unit time. 2. Reduced production costs: By eliminating manual feeding, turning, and loading processes, not only is reliance on manual labor reduced, lowering labor costs, but the risks of errors caused by manual operation are also avoided. Furthermore, the automated collaboration between the transfer and turning mechanisms reduces equipment idle time and energy consumption, lowering equipment operating losses and saving overall costs in the production process. 3. This design organically combines the turning mechanism with the transfer mechanism and the forming mold to form a complete automated processing flow, reducing the number of manual intervention links and making the equipment more in line with the development trend of automation and intelligence in modern industrial production. It helps enterprises to upgrade the automation of their production lines and improve their overall production management level and market competitiveness.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] This utility model provides an automatic pipe forming machine with a turning head.

[0024] In this embodiment, refer to Figure 1-5 The automatic pipe forming machine includes a support 22, a worktable 23, a transfer mechanism 24, and forming molds 25. There are two forming molds 25, which are respectively located on both sides of the worktable. A turning mechanism for rotating the pipe 90° to turn it around is provided between the two forming molds.

[0025] In the above-described solution, the automatic pipe forming machine includes a frame, a worktable, a transfer mechanism, and two forming molds located on either side of the worktable. The core component is a turning mechanism added between the two forming molds, which allows the pipe to rotate 90° to achieve a turnaround. During operation, after one forming mold completes processing at one end of the pipe, the transfer mechanism moves the pipe to the turning mechanism, which rotates it 90° to turn it around. The transfer mechanism then moves the turned pipe to the other forming mold for processing at the other end.

[0026] By coordinating the turning and transfer mechanisms, the traditional steps of unloading pipe fittings and manually turning them over to reload them are eliminated, enabling continuous and automated processing of both ends of the pipe fittings. This significantly shortens the processing cycle, greatly improves production efficiency, reduces manual intervention, minimizes errors caused by human operation, and ensures processing accuracy.

[0027] Specifically, the turning mechanism includes a fixed base 26 and a rotating cylinder gripper 27 disposed on the fixed base 26.

[0028] In this embodiment, the turning mechanism consists of a fixed base and a rotary cylinder gripper mounted thereon. The fixed base provides stable support for the entire turning mechanism, and the rotary cylinder gripper can hold the pipe and rotate it 90° under the drive of the rotary cylinder, thereby completing the turning action of the pipe.

[0029] Specifically, the transfer mechanism is a truss robot, which is equipped with at least two robotic arms 28 for gripping the pipe fittings.

[0030] In this embodiment, the transfer mechanism employs a scaffolding robot, which has at least two robotic arms for gripping the pipe fittings. The scaffolding robot features flexible movement trajectories and high positioning accuracy. The two robotic arms can be responsible for transferring the pipe fittings between different workstations. For example, one robotic arm can transfer a pipe fitting with one end processed from the forming mold to the turning mechanism, while the other robotic arm can simultaneously transfer the turned pipe fitting from the turning mechanism to another forming mold, thus achieving parallel processing of the transfer actions and improving production efficiency.

[0031] Specifically, it also includes a feeding mechanism 29, which includes a frame 1 with a storage bin 5, a lifting assembly 2, a conveying mechanism 3, and a rotating and uprighting mechanism 4; The lifting component 2 is installed inside the storage bin and is used to push the straight pipe out of the storage bin to the conveying mechanism; The rotating upright mechanism 4 is located at the end of the conveying mechanism. The rotating upright mechanism includes a rotating cylinder 6, a receiving base 7 connected to the output end of the rotating cylinder 6, and a sleeve 8 set on the receiving base 7. The sleeve 8 can be fitted into the hole of the straight pipe.

[0032] In this embodiment, the feeding mechanism consists of a frame with a storage bin, a lifting assembly, a conveying mechanism, and a rotating uprighting mechanism. The lifting assembly pushes a straight pipe out of the storage bin to the conveying mechanism. The straight pipe is conveyed horizontally on the conveying mechanism and then enters the rotating uprighting mechanism at its end. A sleeve on the receiving base of the rotating uprighting mechanism fits into the hole of the straight pipe. A rotary cylinder drives the receiving base to rotate, causing the straight pipe to change from a horizontal to an upright position. It realizes an integrated process of straight pipe from storage and conveying to erection, and completes the posture conversion at the end of the conveying, eliminating the need for additional erection process, facilitating subsequent clamping, improving overall processing efficiency, and reducing problems caused by multi-stage transfer.

[0033] Specifically, there are at least two lifting components, including an inclined push plate 9 and a cylinder 10 for driving the push plate 9 to move up and down. The top of the push plate 9 has an inclined surface 11 that is inclined toward the conveying mechanism.

[0034] In this embodiment, there are at least two lifting components, each including an inclined push plate and a cylinder that drives its lifting and lowering. The top of the push plate has an inclined surface that slopes towards the conveying mechanism. When the push plate rises, the inclined surface pushes the straight pipe in the storage bin, and the inclined angle causes the straight pipe to roll towards the conveying mechanism and be pushed to the conveying mechanism.

[0035] The push plates of multiple lifting components are arranged in a stepped manner and work together. The straight tube gradually moves from the bottom push plate to the inclined surface of the next higher push plate until it rolls towards the conveying mechanism.

[0036] Specifically, the conveying mechanism includes a support plate 12, a conveying motor 13, a conveyor belt 14, and long baffles 15 and short baffles 16 located on both sides of the conveyor belt. The support plate is fixed on one side of the frame, the conveying motor and the conveyor belt are mounted on the support plate, and a material conveying channel 17 is formed between the long baffles and the short baffles. The material conveying channel is provided with a feed inlet 18 on one side of the storage bin.

[0037] In this embodiment, the support plate of the conveying mechanism is fixed to one side of the frame. The conveying motor drives the conveyor belt to rotate. The long baffles and short baffles on both sides of the conveyor belt form a material conveying channel. The material conveying channel receives the straight pipe pushed by the lifting component through the inlet on the side of the storage bin. The straight pipe is stably conveyed in a horizontal position within the material conveying channel. The material conveying channel formed by the long baffles and short baffles restricts the conveying path of the straight pipe, preventing it from deviating from its direction or falling during conveying, thus ensuring the accuracy and stability of the straight pipe conveying. The inlet facilitates the smooth entry of the straight pipe into the conveying channel.

[0038] Specifically, the receiving base includes a base plate 20 connected to the output end of the rotary cylinder and a receiving plate 21 connected to the base plate 20. The sleeve is vertically arranged on the receiving plate, and the receiving plate is set at 90° with the base plate.

[0039] In this embodiment, the base plate of the receiving base is connected to the output end of the rotary cylinder, and the receiving plate is set at 90° to the base plate. When the straight pipe is conveyed to the end, it will be fitted onto the sleeve on the receiving plate. Then, the rotary cylinder drives the base plate to rotate, and the receiving plate rotates accordingly, causing the straight pipe to complete the conversion from a horizontal to a vertical position.

[0040] Please note to all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
