Description

Technical Field

[0001] The utility model relates to the technical field of tube plate processing, in particular to a cutting mechanism, an automatic tube flattener and automatic tube flattening equipment. Background Art

[0002] Tube sheets are particularly prone to having numerous tubes inserted into them and requiring expansion joints to secure them. During the expansion jointing process, errors in tube length can cause the tube ends to not be completely flush. Therefore, the installed tubes must be leveled to ensure that all tube ends extend to the same length above the tube sheet surface.

[0003] To address this, manual labor is commonly used, with skilled workers using handheld mechanical pipe levelers to level overlong pipes one by one. However, for tubesheet equipment with a large number of pipes, manual labor is inefficient and can lead to unstable pipe leveling accuracy. This results in low efficiency and unstable precision.

[0013] Optionally, the knife seat is provided with a second through hole, the rod-shaped member is inserted into the second through hole, and the rod-shaped member and the second through hole are rotatably engaged via a plurality of second bearings.

[0014] Multiple second bearings are located between the front end and the rear end of the rod-shaped member, and the rear end of the rod-shaped member is detachably connected to a limiting member, which is used to prevent the rod-shaped member from detaching from the second bearing.

[0018] The technical effects of the utility model include at least:

[0019] During operation, the automatic actuator first drives the cutter holder close to the tube sheet. The automatic actuator then inserts the rod-shaped member into the pipe end to be flattened, acting as a guide. The driver then rotates the cutter holder, driving the multiple cutting blades at the front end to rotate. These cutting blades are arranged around the rod-shaped member.

Combined with the above-mentioned multiple cutting blades arranged around the rod-shaped member, the flat pipe length and the flatness of the pipe end are ensured to be stable.

[0020] Thereby, the efficiency of pipe leveling operation is improved and the stability of pipe leveling accuracy is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figures 1 to 4 This embodiment provides a cutting mechanism for an automatic actuator, wherein the automatic actuator is provided with a driver 310, and the cutting mechanism includes:

[0033] The tool holder 100 is in driving connection with the driver 310 . A plurality of cutting blades 130 are provided at the front end of the tool holder 100 . The driver 310 drives the tool holder 100 to rotate, so that the cutting blades 130 cut the tube ends at the tube sheet.

[0034] The rod-shaped member 150 is rotatably connected to the front end of the tool holder 100 . The plurality of cutting blades 130 are arranged around the rod-shaped member 150 . The rod-shaped member 150 is used to be inserted into the pipe end.

[0035] It should be noted that the automatic actuator here can be a robotic arm, or it can be a linear automatic actuator that can move along the longitudinal, transverse and vertical directions (X, Y and Z axes) and is integrated together, and is mainly composed of a screw and a servo motor.

[0036] In addition, the driver 310 here can be a driving motor for driving the tool holder 100 to rotate.

[0037] During operation, the automatic actuator first drives the cutterhead 100 toward the tube sheet. The automatic actuator then inserts the rod-shaped member 150 into the tube end to be flattened, acting as a guide. The driver 310 then rotates the cutterhead 100, driving the multiple cutting blades 130 at the front end to rotate. These cutting blades 130 are arranged around the rod-shaped member 150. This allows the multiple cutting blades 130 to simultaneously flatten the tube end, improving flattening efficiency. Furthermore, the multiple cutting blades 130 simultaneously rotate the tube end, ensuring a smooth cut. This prevents the rod-shaped member 150 from rotating within the tube and causing friction with the tube wall, potentially damaging the inner wall. The rod-shaped member 150 is rotatably connected to the front end of the blade holder 100. After the rod-shaped member 150 contacts the pipe wall and the blade holder 100 rotates, the rod-shaped member 150 can be rotated relative to the blade holder 100, so that the rod-shaped member 150 remains stationary relative to the pipe wall, thereby protecting the inner wall of the pipe end. After the pipe is leveled, the automatic actuator drives the driver 310, the blade holder 100, and the rod-shaped member 150 to disengage from the pipe and, driven by the automatic actuator, approach the next pipe end that needs to be leveled, thereby automatically leveling multiple pipe ends that need to be leveled one by one. In addition, during this process, the automatic actuator utilizes the characteristic of accurate position movement to enable the automatic actuator to push the blade holder 100 forward only to a set length, ensuring that the leveling length of all pipes is consistent. In combination with the above-mentioned multiple cutting blades 130 arranged around the rod-shaped member 150, the leveling quality of the leveled pipe length and the flatness of the pipe end is guaranteed to be stable.

[0038] Thereby, the efficiency of pipe leveling operation is improved and the stability of pipe leveling accuracy is ensured.

[0039] In addition, the rod-shaped member 150 is inserted into the pipe, which can reduce the vibration and shaking generated during the driving process of the driver 310, thereby ensuring that the pipe end is cut smoothly.

[0040] See also Figures 1 to 4 Furthermore, the driver 310 is a driver 310 of a mechanical automatic tube expander, and the driver 310 is detachably connected to the tool holder 100 .

In particular, the driver 310 is detachably connected to the tool holder 100, allowing the tool holder 100 to be attached to the mechanical automatic tube expander when tube leveling is required. When mechanical tube expansion is required, the tool holder 100 is removed and replaced with a mechanical expansion gun, such as a deep hole adjustment tube expander. The expansion operation is then carried out under the forward motion of the automatic actuator, thereby expanding the scope of application of the mechanical automatic tube expander.

[0057] Multiple second bearings 120 are located between the front end and the rear end of the rod-shaped member 150. The rear end of the rod-shaped member 150 is detachably connected to a limiting member 151. The limiting member 151 is used to prevent the rod-shaped member 150 from detaching from the second bearing 120.
