[0025] Example
[0026] like Figure 1-3As shown, the present embodiment provides a large-scale pipe crimping machine, including a machine platform 1, the bottom of the machine platform 1 is supported by four legs, a driving mechanism 2 is embedded at one end of the table top of the machine platform 1, and a pipe crimping mechanism 3 is embedded at the other end of the table top of the machine platform 1, the driving mechanism 2 is transmission-connected with the pipe crimping mechanism 3, and the pipe crimping mechanism 3 is driven by the driving mechanism 2 to perform pipe crimping operation on the pipe, a support platform 43 is arranged below the pipe crimping mechanism 3, and the support platform 43 is used to support the end of the pipe, and a lifting component 4 is arranged at a position below the bottom of the machine platform 1 below the pipe crimping mechanism 3, the lifting component 4 is transmission-connected with the support platform 43, and the support platform 43 is driven by the lifting component 4 to be lifted and lowered.
[0027] Specifically, the lifting assembly 4 includes a mounting frame 41 fixedly connected to the bottom of the machine platform 1 by bolts, and a lifting cylinder 42 is fixedly connected to the surface of the mounting frame 41 by bolts. The output end of the lifting cylinder 42 is fixedly connected to the bottom of the support platform 43. The support platform 43 is driven to rise and fall by the lifting cylinder 42, thereby changing the position of the pipe, so that the specified position of the pipe is aligned with the pipe pressing mechanism 3, thereby achieving precise pipe pressing.
[0028] In this embodiment, the driving mechanism 2 includes a cylinder 21 embedded in the machine 1, and the output shaft of the cylinder 21 is bolted and fixed with a V-shaped push block 22 with a "V"-shaped cross-section. One end of the V-shaped push block 22 is connected to the pipe pressing mechanism 3, and the V-shaped push block 22 is driven by the cylinder 21 to move in the direction of the pipe pressing mechanism 3, pushing the pipe pressing mechanism 3 to close and perform a pipe pressing operation on the pipe. The oil inlet and oil outlet ends of the cylinder 21 are connected with an oil block 23, and the oil block 23 is connected with a pipeline interface 24 through a pipeline. The pipeline interface 24 has two corresponding to the oil inlet and oil outlet ends of the cylinder 21, and is fixedly installed on the side of the machine 1 through a pipeline clamp. The two pipeline interfaces 24 are respectively connected to the oil inlet and oil outlet ends of the cylinder 21, thereby realizing oil inlet and oil outlet.
[0029] In addition, a solenoid valve 25 is provided between the oil circuit block 23 and the pipeline interface 24 , and the solenoid valve 25 is used to control the on-off state, thereby realizing the control of the oil inlet and outlet of the oil cylinder 21 .
[0030] Specifically, the tube pressing mechanism 3 includes four tube pressing blocks 31 and four connecting blocks 32, each of the connecting blocks 32 is respectively arranged between two of the tube pressing blocks 31, and the two ends of each of the connecting blocks 32 are respectively connected to the tube pressing blocks 31 through elastic members 33, the tube pressing blocks 31 close to the V-shaped push blocks 22 are arranged against the V-shaped push blocks 22, and the front ends of each of the tube pressing blocks 31 and the connecting blocks 32 are detachably connected with a pressing plate 34, the pressing plate 34 is an arc-shaped plate, and eight of the pressing plates 34 are combined to form a circular tubular structure. Among them, when the four tube pressing blocks 31 and the four connecting blocks 32 are squeezed by the V-shaped pushing block 22, the inner surfaces of the four tube pressing blocks 31 and the four connecting blocks 32 form a circle. At this time, the pressing plates 34 located at the front ends of the tube pressing blocks 31 and the connecting blocks 32 are simultaneously closed into a circular tube shape. The products that need to be pressed are placed in the middle of the tube pressing mechanism 3 in advance, and then one of the tube pressing blocks 31 is squeezed by the V-shaped pushing block 22 to make the squeezed tube pressing block 31 move toward the direction of other tube pressing blocks 31. During the movement, the elastic members 33 at both ends of the connecting block 32 are compressed. In this embodiment, the elastic member 33 is a return spring. The elastic member 33 is compressed to make the four tube pressing blocks 31 and the four connecting blocks 32 fit tightly, so as to perform the tube pressing operation on the products that need to be pressed. After the tube pressing is completed, the V-shaped pushing block 22 leaves the tube pressing block 31 under the action of the oil cylinder 21, and the initial shape is restored by the elastic member 33.
[0031] Furthermore, the machine 1 is respectively bolted with a plurality of limit plates 5 at both ends of the tube pressing mechanism 3, and the limit plates 5 are arranged with clearances between the tube pressing block 31. By installing a plurality of limit plates 5 at both ends of the machine 1 at the tube pressing mechanism 3, the tube pressing block 31 is limited. The limit plates 5 at both ends also form a movable groove for the tube pressing block 31 to move, and guide the movement of the tube pressing block 31, so that the tube pressing block 31 moves to the specified position.
[0032] Specifically, a controller 6 is fixedly connected to the surface of the machine 1 through a connecting bracket. The controller 6 is signal-connected to the driving mechanism 2. A touch screen and a control switch are embedded on the surface of the controller 6. The control switch includes a mold opening switch, a mold closing switch and an emergency stop switch. The working parameters are displayed on the touch screen. The mold opening switch drives the oil cylinder 21 to contract and open the tube pressing mechanism 3. The mold closing switch drives the oil cylinder 21 to extend and extrude the tube pressing mechanism 3 to close the mold. The emergency stop switch is used to stop the equipment from working.
[0033] Furthermore, a camera 7 is bolted fixedly installed at a position near the tube crimping mechanism 3 at the bottom of the machine 1, and a display screen 8 is bolted fixedly installed at the top of the controller 6. The camera 7 and the display screen 8 are electrically connected. The camera 7 is used to capture the image of the bottom of the tube crimping machine. When the user controls the device through the controller 6, the position of the tube and the tube crimping process can be intuitively observed through the display screen 8. The user can observe and operate at the same time, which is more convenient.
