Description

Technical Field

[0001] This utility model relates to steel pipe processing equipment, specifically to a steel pipe press-fitting machine. Background Technology

[0002] Press fitting machines are pressure processing equipment widely used in industrial manufacturing, mainly for pressing, forming, and straightening of metal or non-metal materials. Press fitting machines are generally divided into hydraulic press fitting machines, servo press fitting machines, and pneumatic / pneumatic-hydraulic booster press fitting machines. Hydraulic press fitting machines use a hydraulic system as the power source, generating pressure through oil cylinders, and are suitable for pressing large workpieces. Servo press fitting machines are driven by servo motors, offering high precision (repeat positioning accuracy ±0.01mm) and supporting real-time monitoring of pressure-displacement curves, making them suitable for assembling precision electronic components, motor stators, etc. Pneumatic / pneumatic-hydraulic booster press fitting machines use compressed air as power, are economical and practical, and are suitable for pressing small and medium-sized parts (such as bolts and rivets), but have limited pressure output.

[0003] In the current steel pipe pressing process, a pressing machine is generally required. Existing pressing machines are generally equipped with a clamping mechanism for holding the steel pipe. To ensure the stability of the steel pipe clamping, the clamping mechanism is generally composed of a bend clamping component and a straight pipe auxiliary clamping component. The bend clamping component clamps the bend of the steel pipe, while the straight pipe auxiliary clamping component clamps the straight part of the steel pipe, thereby completely fixing the steel pipe. However, the height of the existing straight pipe auxiliary clamping component is not adjustable, so the applicability of the clamping mechanism is relatively poor. Utility Model Content

[0007] The height adjustment mechanism includes four adjusting bolts and two abutting bolts; the four adjusting bolts are located at the four corners of the bottom clamping seat, and the lower ends of the adjusting bolts all pass through the bottom clamping seat and are threadedly connected to the clamping platform; the two abutting bolts are located on both sides of the bottom clamping seat; the abutting bolts are threadedly connected to the clamping platform, and the bottom ends of the abutting bolts pass through the clamping platform and abut against the bottom of the bottom clamping seat.

[0008] A throttle is connected to the front end of the bushing.

[0009] The bushing has two connecting plates connected to its front end, and the bushing has a plug hole at its front end; the throttle front end is inserted into the plug hole and connected to the two connecting plates by bolts.

[0010] The rotating connecting seat is connected to the clamping platform by bolts.

[0011] The technical effects achievable by this utility model are as follows: In clamping steel pipes, the bent section of the steel pipe is clamped by the rear and front clamping seats of the bent pipe clamping assembly, while the straight section of the steel pipe is clamped by the bottom clamping seat and upper limit cap of the straight pipe auxiliary clamping assembly. Furthermore, the straight pipe auxiliary clamping assembly is designed to be height-adjustable via a height adjustment mechanism. Therefore, when the height of the straight section relative to the bent section of the steel pipe changes, this utility model can make corresponding adjustments, thus enhancing its applicability.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] See Figures 1 to 7 .

[0022] A steel pipe pressing machine includes a workbench 1, a clamping platform 2 connected above the workbench 1, and a pressing mechanism 3 located above the clamping platform 2. A pipe bending clamping assembly and a straight pipe auxiliary clamping assembly are connected to the clamping platform 2. The pipe bending clamping assembly includes a rear clamping seat 4, a front clamping seat 5, a rotating connecting seat 6, and a bushing 7. The rear clamping seat 4 is integral with the clamping platform 2. A threaded connecting rod 8 is connected to the front side of the front clamping seat 5. The bushing 7 is rotatably connected to the rotating connecting seat 6 and threadedly connected to the threaded connecting rod 8. By rotating the bushing 7, the front clamping seat 5 is pushed to move back and forth, thereby adjusting the distance between the rear clamping seat 4 and the front clamping seat 5. The rotating connecting seat 6 is fixed to the clamping platform 2. Specifically, the rotating connecting seat 6 is connected to the clamping platform 2 by bolts.

[0023] To facilitate the rotation of the bushing 7, this utility model has a handle 21 connected to the front end of the bushing 7. Specifically, two connecting plates 22 are connected to the front end of the bushing 7, and the front end of the bushing 7 has an insertion hole 23. The front end of the handle 21 is inserted into the insertion hole 23 and connected to the two connecting plates 22 by bolts. It is more convenient to rotate the bushing 7 by the handle 21.

[0024] This utility model relates to a pipe bending clamping assembly for clamping the bent portion of a steel pipe. Specifically, the bent portion of the steel pipe is placed between the rear clamping seat 4 and the front clamping seat 5. Then, the bushing 7 is rotated to push the clamping seat 5 backward until the bent portion of the steel pipe is clamped between the rear clamping seat 4 and the front clamping seat 5 (see reference). Figure 2 , 3 5); When it is necessary to remove the bent part of the steel pipe, the bushing 7 is rotated in the opposite direction to move the clamping seat 5 forward until the bent part of the steel pipe can be removed between the rear clamping seat 4 and the front clamping seat 5.

[0025] The straight pipe auxiliary clamping assembly includes a bottom clamping seat 10 and an upper limit cover 9. The bottom clamping seat 10 is connected to the clamping platform 2 through a height adjustment mechanism, which is used to adjust the height of the bottom clamping seat 10.

The two abutting bolts 12 are located on both sides of the bottom clamping seat 10, and the abutting bolts 12 are threadedly connected to the clamping platform 2, and the bottom ends of the abutting bolts 12 pass through the clamping platform 2 and abut against the bottom of the bottom clamping seat 10.

[0026] This invention relates to the clamping of the straight section of a steel pipe. The straight section of the steel pipe is placed on the bottom clamping seat 10, and then the upper limit cap 9 is bolted to the bottom clamping seat 10, thus clamping the straight section of the steel pipe between the bottom clamping seat 10 and the upper limit cap 9 (see reference). Figure 7 Regarding the connection of the bottom clamping seat 10, the bottom clamping seat 10 of this utility model is connected to the clamping platform 2 through a height adjustment mechanism. Therefore, in use, the height of the bottom clamping seat 10 can be adjusted, that is, the height of the straight tube auxiliary clamping component can be adjusted; Reference Figure 2 , 3 When the height of the straight section of the steel pipe relative to the bent section of the steel pipe changes, the height of the bottom clamping seat 10 can also be changed by rotating the four adjusting bolts 11 and the two abutting bolts 12, thus making it suitable for the steel pipe. Therefore, the applicability of this utility model is better.
