[0002] Tube Angle Forming is the process of forming a tubular workpiece using a stamping process to form a desired angle or shape at a specific location. This process usually involves the use of a hydraulic press or other forming equipment to change the shape of the tubular workpiece by applying force and pressure to give it a specific angle or curve. Tube Angle Forming is commonly used to manufacture various pipes, pipe connectors, body components, and other workpieces that require specific angles or shapes.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5, the utility model provides an embodiment: a hydraulic punching machine for pipe angle forming, including a workbench 1, a top side of the workbench 1 is fixedly connected with a U-shaped frame 3, the top outer surface of the U-shaped frame 3 is fixedly connected with a cylinder 7, the output end of the cylinder 7 is fixedly connected with a sliding plate 5, a T-shaped slot 17 is provided inside the sliding plate 5, a T-shaped block 15 is slidably connected inside the T-shaped slot 17, a punching knife 11 is fixedly connected to the bottom of the T-shaped block 15, a consolidation block 9 is fixedly connected to the outer side of the T-shaped block 15, a fixing slot 20 is provided inside the consolidation block 9, a mounting block 8 is fixedly connected to the outer side of the sliding plate 5, a moving plate 22 is slidably connected to the inner side of the mounting block 8, a clamping block 21 is fixedly connected to one side of the moving plate 22, a pull rod 18 is fixedly connected to the other side of the moving plate 22, a spring 2 16 is sleeved on the outer side of the pull rod 18, a latch 19 is slidably connected to the outer side of the pull rod 18, and a moving component is installed on the outer side of the bottom of the U-shaped frame 3.
[0031] Specifically, the workbench 1 provides an installation platform for the U-shaped frame 3 and also provides a working platform for the staff. Under the action of the cylinder 7, the sliding plate 5 can move up and down. With the cooperation of the T-slot 17 and the T-block 15, the punching knife 11 can be replaced. The punching knife 11 is used to cut the pipe 12. A fixing groove 20 is opened inside the consolidation block 9 to fix the T-block 15 to prevent the T-block 15 from falling off the T-slot 17, thereby causing damage to the device and the staff. Under the action of the latch 19, it is effectively prevented that when the punching knife 11 is moving, the pull rod 18 slides and the punching knife 11 falls off. Under the action of the pull rod 18, the moving plate 22 is driven to move, so that the moving plate 22 slides along the inner wall of the mounting block 8, and then the block 21 is driven to move, so that the block 21 is disengaged from the fixing groove 20 or inserted into the fixing groove 20, thereby achieving the effect of fixing and removing the T-block 15.
[0032] Reference Figure 1 , Figure 2 and Figure 3 The moving component includes a motor 2, the output end of the motor 2 is fixedly connected to a threaded rod 13, the bottom outer side of the U-shaped frame 3 is slidably connected to two fixed molds 10, the top of the fixed mold 10 is fixedly connected to a pipe 12, and a threaded hole 14 is opened inside the fixed mold 10.
[0033] Specifically, when it is necessary to open holes of different sizes in the pipe 12, not only the punch 11 needs to be replaced, but also the distance between the two fixed molds 10 needs to be adjusted. At this time, by starting the motor 2, the threaded rod 13 rotates on the outside of the bottom of the U-shaped frame 3 under the action of the output end of the motor 2, and the fixed mold 10 can move in opposite directions under the action of the threaded hole 14 opened inside the fixed mold 10, so that the distance between the two fixed molds 10 can be adjusted.
[0034] Reference Figure 2 A plurality of fixing rods 6 are fixedly connected to the outer side of the bottom of the U-shaped frame 3, and a spring 4 is sleeved on the outer side of the fixing rod 6.
[0035] Specifically, under the action of the fixing rod 6, the stable sliding of the sliding plate 5 is ensured, and under the action of the spring 14, the punching knife 11 has a buffering effect when impacting the pipe 12.
[0036] Reference Figure 5 The longitudinal section of the clamping block 21 is square, and the clamping block 21 and the fixing groove 20 are plug-fitted.
[0037] Specifically, the longitudinal section of the clamping block 21 is square, which can be better plugged into and matched with the fixing groove 20, making it convenient for the staff to use.
[0038] Reference Figure 5 One end of the spring 16 is fixedly connected to one side of the moving plate 22 , and the other end of the spring 16 is fixedly connected to the inner wall of the mounting block 8 .
[0039] Specifically, under the action of the second spring 16 , it is ensured that the buckle structure can be used stably and reasonably, thereby preventing the pull rod 18 from moving randomly and ensuring that the block 21 can be tightly buckled in the fixing groove 20 .
[0040] Reference Figure 2 One end of the spring 1 4 is fixedly connected to one side of the bottom of the sliding plate 5 , and the other end of the spring 1 4 is fixedly connected to the outer side of the bottom of the U-shaped frame 3 .
[0041] Specifically, under the action of the spring 14, the impact of the punch 11 when cutting the pipe 12 is buffered, thereby reducing the damage to the device to a certain extent.
[0042] Reference Figure 2 The sliding plate 5 is slidably connected to the plurality of fixing rods 6 , and the latch 19 is slidably connected to the sliding plate 5 .
[0043] Specifically, under the action of the fixing rod 6, the stable up and down movement of the sliding plate 5 is ensured. Under the action of the latch 19, the impact force generated by the sliding plate 5 when driving the punching knife 11 to slide is prevented from causing the pull rod 18 to shake, resulting in the falling off of the punching knife 11 and causing damage to people and machines.
[0044] Reference Figure 2 and Figure 3 The outer side of the threaded rod 13 is rotatably connected to the outer side of the bottom of the U-shaped frame 3, and the threaded rod 13 and the threaded hole 14 are threadedly connected.
[0045] Specifically, the U-shaped frame 3 provides a rotation space for the threaded rod 13. With the cooperation of the threaded rod 13 and the threaded hole 14, the two fixed dies 10 can move in opposite directions to achieve the effect of adjusting the distance between the two fixed dies 10 and thus adjusting the cutting angle.
[0046] Working principle: When punching is required, the cylinder 7 is started to drive the sliding plate 5 to move up and down, and then drive the movement of the punching knife 11, so that the punching knife 11 breaks through the top surface of the pipe 12 and fits with the two fixed molds 10. When it is necessary to replace a different punching knife 11 to cut the pipe 12 at different angles, the pin 19 is pulled out, and then the pull rod 18 is pulled to drive the movement of the moving plate 22, and then drive the movement of the card block 21, so that the card block 21 is separated from the fixed groove 20. At this time, the T-block 15 is separated from the T-slot 17, so that the punching knife 11 is disassembled and replaced. When other punching knives 11 need to be installed, the T-block 15 is placed in the T-slot 17, and then the consolidation block 9 is aligned with the mounting block 8, and then the pull rod 18 is released. Under the elastic action of the spring 2 16, the movable plate 22 is pushed to move, and then the block 21 is driven to move, so that the block 21 is stuck in the fixed groove 20, and then the pin 19 is inserted into the pull rod 18, so that one end enters into the sliding plate 5, thereby completing the fixation of the T-block 15, that is, the punching knife 11 is fixed. When it is necessary to replace the punching knife 11 of different types, the distance between the two fixed molds 10 also needs to be adjusted. At this time, by starting the motor 2, under the action of the output end of the motor 2, the threaded rod 13 is driven to rotate, so that the two fixed molds 10 move in opposite directions along the outer surface of the threaded rod 13, so as to ensure that the mouth shape of the fixed mold 10 matches the punching knife 11.
[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
