Description

Technical Field

[0001] This invention relates to the field of machine tools or devices for shearing or cutting pipes, and more specifically to a beveling equipment for the production of metal mesh shells. Background Technology

[0002] Pipe beveling machines (also known as pipe beveling machines or chamfering machines) are specialized equipment used for beveling the front end face of pipes during welding. They are mainly divided into two types: internal expansion type and external clamping type. The external clamping type includes electric, pneumatic and hydraulic drive types, which clamp the outer diameter of the pipe through a two-part chuck.

[0003] Metal grid shell structures belong to the spatial structure system and are widely used in various large-span structures due to their characteristics such as high spatial stiffness, good load-bearing performance, low material consumption, light weight, and excellent seismic performance. The manufacturing process of metal grid shell spatial structure systems requires a large number of metal tubes that need to be beveled.

[0004] Existing beveling machines require each group of pipes to be individually fixed when beveling multiple metal pipes, which is very time-consuming when there are a large number of pipes to be beveling. Furthermore, while fixing a single pipe and adjusting the clamping position can accommodate pipes with small size differences, batch beveling requires structural modifications to the beveling machine to accommodate different pipe sizes, which is both time-consuming and labor-intensive. Summary of the Invention

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, the present invention provides a beveling processing device for the production of metal mesh shells, including a support frame 1, a cutting device and a fixing device 2 fixedly connected to the support frame 1; the fixing device 2 includes a reciprocating drive mechanism 26, the drive mechanism 26 is connected to a drive plate 27, a first connecting rod 21 is fixedly connected to both ends of the drive plate 27, a second connecting rod 22 is hinged to the end of the first connecting rod 21 facing away from the drive plate 27, a third connecting rod 23 is hinged to the end of the second connecting rod 22 facing away from the first connecting rod 21, a fourth connecting rod 24 is hinged to the end of the third connecting rod 23 facing away from the second connecting rod 22, a movable frame 29 is hinged to the end of the fourth connecting rod 24 facing away from the third connecting rod 23, and a fixed frame 28 is slidably connected to the upper part of the movable frame 29. A fifth connecting rod 25 is hinged to the fifth connecting rod 25, which is fixedly connected to the end of the fixed frame 28. A first clamping assembly is provided at the lower part of the movable frame 29. The first clamping assembly includes a first clamping plate 31. Several second clamping assemblies are provided between the two first clamping plates 31. The second clamping assembly includes a slider 33, which is slidably connected to the fixed frame 28. A first connecting rod 341 is fixedly connected to the lower part of the slider 33. A second connecting rod 342 is fixedly connected to the end of the connecting rod facing away from the slider 33. The two ends of the second connecting rod 342 are fixedly connected to the second clamping plates 32. The cutting device includes a cutting ring 4. A movable seat is installed on the cutting ring 4. A cutting knife seat is slidably installed on the movable seat. A beveling knife is fixedly installed on the cutting knife seat. The movable seat rotates around the center of the cutting ring 4. Through the cooperation of the first clamping assembly and the second clamping assembly, multiple metal tubes 10 can be beveling in batches. The first clamping assembly, through the cooperation of the first connecting rod 21, the second connecting rod 22, the third connecting rod 23, the fourth connecting rod 24, and the fifth connecting rod 25, clamps the metal tube 10. The main reaction force is borne by the third connecting rod 23, minimizing the impact on the drive mechanism 26. Compared to the prior art where the reaction force is transmitted to the drive mechanism 26 through the grippers during beveling of the metal tube 10, this invention provides a larger clamping force without affecting the drive mechanism 26 or the equipment's lifespan. It offers a larger clamping force and stable clamping effect. Both the first clamping plate 31 and the second clamping plate 32 have built-in pressure sensors, which are connected to the controller via signal lines. The pressure sensors and the controller adjust the force between the first clamping mechanism and the metal tube 10 when clamping it, preventing the clamping from being too loose or too tight.

[0022] The first clamping assembly also includes a ball screw 36, which includes a screw and a nut. A clamping plate 31 is fixedly connected to a clamping plate seat, which is also fixedly connected to the nut. By rotating the screw, the nut moves along the screw, thereby adjusting the position of the first clamping plate 31. When different sizes of metal tubes 10 are replaced for beveling, rotating the screw moves the nut along the screw, thereby moving the first clamping plate 31 toward or away from the metal tube 10 for clamping. This allows the invention to be adapted to various sizes of metal tubes 10. Limiting seats 35 are provided at both ends of the screw, and the first clamping plate 31 is disposed between the two limiting seats 35. The limiting seats 35 are rotatably connected to the screw.

[0023] In one embodiment of the present invention, the beveling equipment further includes a limiting device, which includes a limiting plate 5 disposed at the end of the metal tube 10 facing away from the first clamping assembly. The limiting plate 5 is connected to a limiting drive assembly that drives the limiting plate 5 to reciprocate along the axial direction of the metal tube 10. The limiting device also includes a pressure sensor that monitors the pressure between the limiting plate 5 and the metal tube 10. The pressure sensor is electrically connected to a controller, and the controller is electrically connected to the limiting drive assembly to control the action of the limiting drive assembly. After the metal tube 10 is in place, a hydraulic cylinder or a pneumatic cylinder pushes the limiting plate 5 toward the metal tube 10 and into contact with it. The pressure sensor monitors the pressure value between the limiting plate 5 and the metal tube 10 in real time and transmits the pressure signal to the controller in real time. When the pressure sensor detects that the pressure exceeds a preset value, the controller controls the pneumatic cylinder or hydraulic cylinder to stop moving, thereby stopping the movement of the limiting plate 5. At this time, the first clamping assembly, the second clamping assembly, and the limiting plate 5 cooperate to fix the metal tube 10, and then the beveling cutter performs beveling.

[0024] like Figure 4 and Figure 5 As shown, the limiting device also includes a support assembly. The limiting plate 5 has a through hole to allow the support assembly to pass through and enter the metal tube 10. The support assembly includes a support rod 6, on which a first support seat 61 is fixedly connected. A second support seat 62 and a third support seat 63 are slidably connected to the support rod 6. The second support seat 62 is disposed between the first support seat 61 and the third support seat 63. Multiple first support rods 71 ​​are hinged to the first support seat 61 in the circumferential direction. Multiple second support rods 72 are hinged to the second support seat 62 in the circumferential direction. Multiple third support rods 73 are hinged to the third support seat 63 in the circumferential direction. A first support plate 741 is hinged to the end of the first support rod 71 and the second support rod 72 facing away from the support rod 6. A third support plate 743 is hinged to the end of the second support rod 72 and the third support rod 73 facing away from the support rod 6. Figure 4 As shown, the third support seat 63 is moved towards the first support seat 61 by a cylinder or hydraulic cylinder, and the first support plate 741 and the third support plate 743 move away from the support rod 6 to contact the inner wall of the metal tube 10 for support; or, as Figure 5 As shown, the third support seat 63 is moved away from the first support seat 61 by a cylinder or hydraulic cylinder, while the first support plate 741 and the third support plate 743 move towards the support rod 6, separating the support assembly from the metal tube 10. A first spring 81 is sleeved on a portion of the support rod 6 between the first support seat 61 and the second support seat 62, and a third spring 83 is sleeved on a portion of the support rod 6 between the second support seat 62 and the third support seat 63, making the support more stable.

[0025] In one embodiment, the first clamping plate 31 has an elastic layer at one end facing the metal tube 10, and the elastic layer has a V-shaped contact surface that contacts the metal tube 10; the second clamping plate 32 has an elastic layer at one end facing the metal tube 10, and the elastic layer has a V-shaped contact surface that contacts the metal tube 10. When the first clamping plate 31 and the second clamping plate 32 contact the metal tube 10, the V-shaped contact surface causes the elastic layer to deform significantly, resulting in a large clamping force between the first clamping plate 31, the second clamping plate 32 and the metal tube 10, and stable clamping. In addition, the V-shaped contact surface allows the first clamping plate 31 and the second clamping plate 32 to adapt to metal tubes 10 of different sizes, resulting in high adaptability.

[0026] In one embodiment, the first clamping plate 31 includes a first clamping plate 31 seat, which is detachably connected to the first clamping plate 31. The first clamping plate 31 is an arc-shaped plate adapted to the metal tube 10. The second clamping plate 32 is an arc-shaped plate, which is detachably connected to the second connecting rod 342. The arc-shaped plate is adapted to the metal tube 10, has a large clamping force, and is stable in clamping. When it is necessary to replace the metal tube 10 of different sizes for beveling, other arc-shaped plates that are adapted to it can be replaced.

[0027] The support frame 1 is also equipped with a cleaning ring 9. Cleaning seats are arranged in an array along the upper semicircle of the cleaning ring 9. Each cleaning seat has an exhaust port. The cleaning ring 9 has an air duct connected to the exhaust port. A fan is also connected to the cleaning ring 9 to provide high-speed airflow into the air duct. This invention simultaneously performs batch beveling on multiple pipes, generating a large amount of debris. The high-speed airflow generated by the fan enters the air duct within the cleaning seat through the pipe, then flows into the exhaust port, and exits through the exhaust port, blowing towards the metal pipe 10 and dislodging the generated debris into the lower debris trough for collection. To prevent excessive heat generation during equipment use and its lifespan, the cleaning ring 9 is also connected to a chiller. The chiller generates cold air that enters the air duct through the pipe, and the cold air entering the air duct is also discharged through the exhaust port, cooling the beveling blades. A weight sensor is built into the debris trough. When the weight reaches a preset value (e.g., 5kg), an audible and visual alert is issued to remind the operator to replace the casing.

[0028] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be covered within the protection scope of the present invention.
