This processing step is generally carried out manually using hydraulic clamps. The above processing method has the following shortcomings: the depth and position of the notches depend on manual judgment, resulting in poor accuracy; the processing efficiency is low, and it is time-consuming and labor-intensive.

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0023] Combination Figure 1 and Figure 2 As shown, the automated production equipment for high-performance corrosion-resistant stainless steel pipes includes a base 1, a fixed seat 2 set on the base 1, a punch 3 connected to the fixed seat 2 for lifting, a pad 4 set on the fixed seat 2 below the punch 3, a limiting plate 5 set on the fixed seat 2 below the pad 4, and a pipe feeding seat 6 set on the base 1.
[0024] The top of the pad column 4 has a corresponding clearance groove 7 for the punch 3. The front end of the clearance groove 7 passes through the front end of the pad column 4. The bottom of the clearance groove 7 is inclined forward and downward to facilitate the discharge of the metal sheet punched down by the punch 3. The inner wall of the side of the notch to be punched at the end of the steel pipe 8 is set to abut the top of the pad column 4.
[0025] The limiting plate 5 is telescopically connected to the fixed base 2, and the lower end of the steel pipe 8 abuts against the limiting plate 5. The limiting plate 5 controls the length of the notch punched at the end of the steel pipe 8 by telescopic movement.
[0026] The pipe feeding seat 6 is provided with a support 9, which is located close to the fixed seat 2. A pressure plate 10 is raised and lowered above the support 9. When the end of the steel pipe 8 is punched, the pressure plate 10 is lowered to clamp the steel pipe 8 between the support 9 and the pressure plate 10 to prevent the steel pipe 8 from shifting when punching the notch.
[0027] The pipe feeding seat 6 is also provided with two sets of support rollers 11. One of the two sets of support rollers 11 is a drive roller. The drive roller is connected to a servo motor. The steel pipe 8 is mounted between the two sets of support rollers 11.
[0028] The working principle of the above structure is as follows: the steel pipe 8 is moved forward under the conveying of the pipe feeding seat 6 until the lower end of the steel pipe 8 abuts against the limiting plate 5 and is limited. At this time, the inner wall of the side of the steel pipe 8 to be punched abuts against the top of the pad column 4. The pressure plate 10 descends to clamp the steel pipe 8, and the punch 3 rises and falls once to punch a notch at the end of the steel pipe 8. After one notch at the end of the steel pipe 8 is punched, the pressure plate 10 returns to its original position. The driving wheel in the two sets of support rollers 11 drives the steel pipe 8 to rotate at a certain angle, so that the position of the other notch at the end of the steel pipe 8 abuts against the pad column 4. The pressure plate 10 descends again to clamp the steel pipe 8, and the punch 3 punches a notch at the end of the steel pipe 8 again. This cycle continues until a suitable number of notches are punched at the end of the steel pipe 8. After processing is completed, the pipe feeding seat 6 outputs the steel pipe 8.
[0029] The advantages of the above structure are: it can realize continuous punching notches at the end of the steel pipe 8, and the whole process does not require manual intervention. Compared with manually processing notches at the end of the steel pipe 8 using hydraulic pliers, the notches processed by the above structure are regular and have good consistency in length. The rotation angle of the steel pipe 8 driven by the active wheel driven by the servo motor is more accurate, eliminating the need to repeatedly measure the position of the notch, and also has the advantage of high processing efficiency.
[0030] In another embodiment, the pipe feeding seat 6 is also provided with multiple sets of conveying wheels that drive the steel pipe 8 to move forward and backward.
[0031] In another embodiment, such as Figure 1 As shown, two sets of support rollers 11 are respectively mounted on two movable seats 12. The two movable seats 12 are respectively movably connected to both sides of the pipe feeding seat 6. The two sides of the pipe feeding seat 6 are also provided with a first screw mechanism 13 to drive the two movable seats 12 to move. The distance between the two movable seats 12 is adjustable to adapt to the processing of steel pipes 8 of different specifications.
[0032] In another embodiment, the pipe feeding seat 6 is vertically connected to the base 1 to adjust the height of steel pipes 8 of different specifications so that the position of the notch to be punched at the end of the steel pipe 8 abuts against the pad post 4.
[0033] In another embodiment, the top of the support 9 and the bottom of the pressure plate 10 are provided with arc-shaped grooves corresponding to the steel pipe 8, and the bottom of the pressure plate 10 is also provided with an elastic pad to better clamp the steel pipe 8.
[0034] In another embodiment, such as Figure 2 As shown, the top of the fixed base 2 is provided with a mounting plate 14, the top of the mounting plate 14 is fixed with a first hydraulic cylinder 15, and a reinforcing plate is also connected between the mounting plate 14 and the fixed base 2.
[0035] In another embodiment, combined Figure 1 and Figure 2As shown, the fixed base 2 is also provided with a guide rail, and a slider 16 is slidably connected on the guide rail. The piston rod of the first hydraulic cylinder 15 is connected to the slider 16. The punch 3 is fixed at the bottom of the slider 16. The first hydraulic cylinder 15 drives the slider 16 and then drives the punch 3 to move up and down.
[0036] In another embodiment, combined Figure 1 and Figure 2 As shown, the support 9 has two columns on top, and a top plate is provided on the top of the two columns. A second hydraulic cylinder 17 is fixed on the top plate, and the piston rod of the second hydraulic cylinder 17 is connected to the top of the pressure plate 10.
[0037] In another embodiment, combined Figure 1 and Figure 2 As shown, guide holes are provided on both sides of the pressure plate 10, and the two columns pass through the corresponding guide holes to make the lifting and lowering of the pressure plate 10 more stable.
[0038] In another embodiment, combined Figure 1 and Figure 2 As shown, the limiting plate 5 is provided with two guide rods 18. The two guide rods 18 pass through the fixed base 2 and are fixed with a connecting plate. The rear end of the fixed base 2 is connected to a second lead screw mechanism 19 through a bracket.
