Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical processing equipment, in particular to a pipe cutting and pressing device. Background Art
[0002] The existing cutting and pressing tube device has a cylinder-driven tube pressing rod on the inner side of the frame, and the tube pressing rod presses the tube to the cutting position. It has the advantages of short lever arm, strong force, and small required cylinder bore. However, the disadvantages are also obvious: if there is a program bug or manual operation error, the arm rotates when the wheel claw is open, which will cause the tube pressing rod and the wheel claw to collide, resulting in damage to mechanical parts, causing shutdown, resulting in production delays and losses, increasing the labor intensity of workers, and the cost is too high. Utility Model Content
[0003] The purpose of the utility model is to solve the defects of the prior art and provide a pipe cutting and pressing device.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A pipe cutting and pressing device comprises a guide rail mounting plate, a guide rail and a cylinder mounting seat arranged on the guide rail mounting plate, a cylinder is arranged on the cylinder mounting seat, a guide rail slider is arranged on the guide rail, a pipe pressing plate mounting block is arranged on one side of the guide rail slider, a pipe pressing plate is arranged on one side of the pipe pressing plate mounting block, the pipe pressing plate is mounted on the pipe pressing plate mounting block through a rotating pin shaft, and a cylinder rod of the cylinder is connected to the rotating pin shaft through a fisheye bearing;
[0006] A fixing pin is provided on the tube pressing plate mounting block, and a connecting pin is provided on the tube pressing plate, and the fixing pin and the connecting pin are connected by a spring;
[0007] A tube pressing plate limiting pin is arranged on the tube pressing plate mounting block, and the end of the tube pressing plate is limited by the tube pressing plate limiting pin.
[0008] Furthermore, a bearing is sleeved on the rotating pin shaft, and an elastic retaining ring for a hole is provided on one side of the bearing.
[0009] Furthermore, spacers are provided on both sides of the bearing.
[0010] Furthermore, a limit block is provided at the end of the guide rail for limiting the guide rail slider.
[0011] Furthermore, the telescopic direction of the cylinder is consistent with the extending direction of the guide rail.
[0012] The beneficial effects of the utility model are as follows: the tube pressing plate (tube pressing rod) of the device has a shorter force arm. Since the cylinder directly acts on the rotating pin shaft, the cylinder diameter can be smaller. At the same time, the cylinder rotates with the big arm. When the wheel claw opens and the rotating big arm rotates, it will not collide with the tube pressing plate (tube pressing rod), effectively avoiding program bugs and equipment problems that may be caused by misoperation.
[0013] The cutting and pressing tube device has the characteristics of good tube pressing effect, easy disassembly, convenient maintenance, long service life, convenient installation, reasonable structure, effective avoidance of collision during roll changing, and benefit to safe operation of the unit. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a schematic diagram of the structure of the utility model;
[0015] Figure 2 It is a structural schematic diagram of the utility model from another angle. DETAILED DESCRIPTION
[0016] Reference Figure 1 , Figure 2 A pipe cutting and pressing device comprises a guide rail mounting plate 1, a guide rail 8 and a cylinder mounting seat 2 arranged on the guide rail mounting plate 1, a cylinder 10 is arranged on the cylinder mounting seat 2, a guide rail slider 16 is arranged on the guide rail 8, a pipe pressing plate mounting block 3 is arranged on one side of the guide rail slider 16, a pipe pressing plate 4 is arranged on one side of the pipe pressing plate mounting block 3, the pipe pressing plate 4 is mounted on the pipe pressing plate mounting block 3 through a rotating pin shaft 6, and a cylinder rod of the cylinder 10 is connected to the rotating pin shaft 6 through a fisheye bearing 9; the telescopic direction of the cylinder 10 is consistent with the extension direction of the guide rail 8.
[0017] A fixing pin 17 is provided on the tube pressing plate mounting block 3, and a connecting pin 15 is provided on the tube pressing plate 4. The fixing pin 17 and the connecting pin 15 are connected by a spring 14; a tube pressing plate limiting pin 5 is provided on the tube pressing plate mounting block 3, and the end of the tube pressing plate 4 is limited by the tube pressing plate limiting pin 5.
[0018] A bearing 11 is sleeved on the rotating pin shaft 6 , a hole elastic retaining ring 12 is provided on one side of the bearing 11 , spacers 7 are provided on both sides of the bearing 11 , and a limit block 13 for limiting the guide rail slider 16 is provided at the end of the guide rail 8 .
[0019] In this embodiment, the guide rail 8 and the cylinder mounting seat 2 are installed on the guide rail mounting plate 1, the tube pressing plate mounting block 3 is installed on the guide rail slider by screws, the bearing 11 is installed on the tube pressing plate 4, and the hole uses an elastic retaining ring 12 to limit the bearing 11 from falling out. There is a spacer 7 on each side of the bearing 11, which is fixed to the tube pressing plate mounting block 3 by a rotating pin 6. Under the action of its own gravity and the tension spring 14, the end of the tube pressing plate 4 is always close to the tube pressing plate limit pin 5, ensuring that the tube pressing plate 4 is always perpendicular to the movement direction of the slider. The cylinder 10 is connected to the rotating pin 6 through the fisheye bearing 9, driving the guide rail slider 16 to move.
[0020] When the pipe is pressed onto the pipe pressing plate 4, the pipe pressing plate 4 rotates around the rotating pin 6 so that the pipe can continue to move downward. When the pipe passes through the front end of the pipe pressing plate 4, the pipe pressing plate 4 returns to its original position under the action of its own gravity and the tension spring 14. At this time, the pipe is located below the pipe pressing plate 4, and the cylinder 10 is ventilated to pull the guide rail slider 16 downward through the rotating pin 6. The pipe pressing plate 4 presses the pipe downward to reach the cutting position, thereby achieving the purpose of cutting the pipe.
[0021] The tube pressing plate 4 (tube pressing rod) of the device has a shorter force arm. Since the cylinder 10 directly acts on the rotating pin 6, the cylinder 10 can have a smaller bore and rotates with the big arm. When the wheel claw opens and the rotating big arm rotates, it will not collide with the tube pressing plate 4 (tube pressing rod), effectively avoiding equipment problems that may be caused by program bugs and misoperation.
[0022] The cutting and pressing tube device has the characteristics of good tube pressing effect, easy disassembly, convenient maintenance, long service life, convenient installation, reasonable structure, effective avoidance of collision during roll changing, and benefit to safe operation of the unit.
