A pipe end trimming machine is a specialized piece of equipment used for trimming, cutting, and processing the ends of steel pipes.

[0003] A utility model patent with patent authorization announcement number CN206343899U discloses a steel pipe flattening machine. The key technical points of the solution include: a cutting working end, a slide rail, a fixed frame, and a base. The base is located above the slide rail and moves along the slide rail. The fixed frame and the cutting working end are fixed on the base. The cutting working end is equipped with a cutter head, a slide rail and a cutting tool are provided on the cutter head, and a wire brush is provided on the cutter head. A rotating motor is provided at one end of the wire brush, and the rotating motor drives the wire brush to rotate.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A flat-end machine for processing 3PE anti-corrosion steel pipes includes a base 1, a fixed frame 2 fixedly connected to the horizontal part of the base 1, a support seat 3 fixedly connected to the inner side wall of the fixed frame 2, a slot one of the support seat 3 contacts the steel pipe body 4, a hydraulic cylinder 5 fixedly installed on the horizontal part of the fixed frame 2, a card seat 6 fixedly connected to the telescopic end of the hydraulic cylinder 5, the card seat 6 is slidably connected to the fixed frame 2, and a slot two of the card seat 6 contacts the steel pipe body 4;

[0024] A cover 7 is slidably connected to the vertical rear part of the fixed frame 2. An end plate 8 is in contact with the horizontal part of the fixed frame 2. A connecting line 9 is fixedly connected to the lower end of the end plate 8. The connecting line 9 is slidably connected to the horizontal part of the fixed frame 2. A blocking plate 10 is fixedly connected to the other end of the connecting line 9. The blocking plate 10 is slidably connected to the horizontal part of the fixed frame 2. A spring 11 is provided on the outside of the connecting line 9.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 One end of the spring 11 is fixedly connected to the blocking plate 10, and the other end of the spring 11 is welded to the end block of the horizontal part of the fixing frame 2. The blocking plate 10 can be connected by the spring 11. A guide 12 is fixedly connected to the horizontal part of the fixing frame 2. The guide 12 is in contact with the connecting line 9. The connecting line 9 can be guided by the guide 12.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 A flat-head mechanism 13 is provided on the base 1. The flat-head mechanism 13 includes a motor 131. The motor 131 is fixedly installed on the vertical part of the base 1. The output shaft of the motor 131 is fixedly connected to a screw 132. A movable plate 133 is threadedly connected to the outside of the screw 132. The movable plate 133 is slidably connected to the inner wall of the base 1. A second motor 134 is fixedly installed on the right end of the movable plate 133. A flat-head sawtooth 13 is fixedly sleeved on the outside of the output end of the second motor 134. 5. A locking hole 136 is provided on the inner wall of the vertical part of the base 1. A telescopic frame 137 is slidably connected to the inner wall of the movable plate 133. A locking ball 138 is fixedly connected to the lower end of the telescopic frame 137. The locking ball 138 is slidably connected to the locking hole 136. With the setting of the motor 134, flat-head saw teeth 135 and other structures, the steel pipe body 4 can be cut and flattened. With the locking hole 136, locking ball 138 and other structures, the position of the flat-head saw teeth 135 can be positioned.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5There are two locking holes 136, which are evenly distributed on the vertical part of the base 1. The locking holes 136 facilitate the use of locking balls 138 for locking. An elastic airbag 139 is bonded to the horizontal part of the telescopic frame 137. The other end of the elastic airbag 139 is bonded to the moving plate 133. The elastic airbag 139 allows the telescopic frame 137 to be connected and used.

[0028] The specific implementation process of this utility model is as follows: When in use, the steel pipe body 4 is placed into the slot 1 of the support seat 3, and the hydraulic cylinder 5 is started to drive the telescopic end to move, so as to drive the seat 6 to move stably along the inner wall of the fixed frame 2, so that the slot 2 of the seat 6 contacts the steel pipe body 4, and finally clamps and fixes the steel pipe body 4.

[0029] The second motor 134 is started to drive the output end to rotate, thereby driving the flat-head saw teeth 135 to rotate. The first motor 131 is started to drive the output shaft to rotate, thereby driving the screw 132 to rotate. Under the threaded connection, the moving plate 133 can be driven to move, thereby driving the second motor 134 to move, so that the flat-head saw teeth 135 can move, and cut and flatten the fixed steel pipe body 4.

[0030] During this process, when the movable plate 133 moves, it can drive the telescopic frame 137 to move, and drive the locking ball 138 to move. Under the pressure of the inner wall of the locking hole 136, the locking ball 138 can be pushed to move, and the elastic airbag 139 deforms, eventually causing the locking ball 138 to disengage from the locking hole 136. Under the action of force, the locking ball 138 slides along the inner side wall of the vertical part of the base 1. When the locking ball 138 slides into the next locking hole 136, the elastic airbag 139 restores its deformation to push the locking ball 138 into the locking hole 136, thereby limiting the movable plate 133 and positioning the flat-head saw teeth 135.

[0031] By pulling the end plate 8 upward, the connecting line 9 is moved, allowing it to move along the surface of the guide 12 to ensure smooth movement. This also moves the blocking plate 10, causing the spring 11 to deform. Ultimately, the guide hole in the horizontal part of the fixing frame 2 is in a flow state, guiding the lubricating oil to contact the extension and retraction end of the hydraulic cylinder 5, thus lubricating the hydraulic cylinder 5 and reducing its extension and retraction resistance.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
