Description

Technical Field

[0001] The utility model specifically relates to the technical field of titanium alloy pipe processing, and specifically is a fixed-length cutting structure for titanium alloy welded pipe processing. Background Technique

[0002] The fixed-length cutting structure for titanium alloy welded pipe processing is a device for cutting titanium alloy welded pipes. After the production of titanium alloy pipes, fixed-length cutting is still required. According to the needs of the occasion, the titanium alloy pipes are cut into the required lengths and then welded.

[0003] However, for the existing part of the titanium alloy pipe cutting structures, they do not have a measurement function. It is necessary for the staff to manually measure, then make marks at the cutting position and then perform cutting. This is relatively slow and cannot guarantee the cutting accuracy.

[0004] There is also a titanium alloy pipe cutting structure with a conveying structure. Generally, symmetrically arranged concave wheels are used for clamping, and the titanium alloy pipe is pushed to move by the rotation of the concave wheels. This requires fixed-length cutting depending on the program, and programming is required before changing the cutting size. The limitation is relatively large. Generally, it is only applicable to batch cutting of one length and cannot meet the fixed-length cutting with frequently changing sizes. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fixed-length cutting structure for titanium alloy welded pipe processing. The titanium alloy pipe is automatically fed through a feeding mechanism. The inclined clamping structure can automatically clamp during feeding and automatically loosen during retraction. Then, in cooperation with an adjustable fixed-length regulator, the cutting length can be adjusted at any time, which is applicable to small-batch processing occasions that require frequent adjustment of the cutting size. To solve the technical problems proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fixed-length cutting structure for titanium alloy welded pipe processing includes a cutting machine and a feeding mechanism. The cutting machine and the feeding mechanism are both fixed on a bottom plate.

[0008] The feeding mechanism includes an electric cylinder, a one-way gripper, and a fixed-length regulator. Among them, the electric cylinders are symmetrically fixed on supports. The supports are fixed on the bottom plate, and the supports are located on the side of the cutting machine. The one-way gripper includes a U-shaped seat. The U-shaped seat is fixed at the end of the electric cylinder, and a swing plate is movably connected in the U-shaped seat. The fixed-length regulator includes a fixing plate fixed on the U-shaped seat and a limiting plate fixed on the electric cylinder, and a sliding rod is movably connected to the inner side of the limiting plate.

[0009] As a further technical solution of the utility model, the end of the swing plate is connected to the U-shaped seat through a pin shaft, and a tension spring is arranged between the U-shaped seat and the swing plate.

[0010] As a further technical solution of the present utility model, one end of the sliding rod penetrates through the limiting plate and is fixedly connected to the fixing plate. A baffle is sleeved on the other end of the sliding rod, and a locking knob is in threaded cooperation at the connection between the sliding rod and the baffle.

[0011] As a further technical solution of the present utility model, the sliding rod is respectively slidably connected to the limiting plate and the baffle, and a contact switch is embedded on one side of the baffle close to the limiting plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, through the inclination direction of the swing plate, when the electric cylinder moves closer to the cutting machine, the swing plate can drive the titanium alloy welded pipe to be processed to move. On the contrary, the swing plate will slide on the surface of the titanium alloy welded pipe to be processed, so as to automatically load the titanium alloy welded pipe to be processed, and the cutting size can be adjusted at any time, which is suitable for the cutting of titanium alloy pipes in small batches with frequently changing sizes.

[0014] 2. In the present utility model, by adjusting the position of the baffle at the end of the sliding rod, the moving distance of the one-way gripper is restricted, so as to adjust the cutting size, and the cutting size can be adjusted frequently as needed.

[0015] 3. In the present utility model, the baffle drives the locking knob to move along with the movement of the sliding rod. When the locking knob touches the side surface of the limiting plate, the locking knob can control the electric cylinder to stop moving, ensuring the accuracy during fixed-length cutting.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-7 , the embodiment of the present utility model provides a fixed-length cutting structure for processing titanium alloy welded pipes, including a cutting machine 2 and a feeding mechanism. The cutting machine 2 and the feeding mechanism are both fixed on the base plate 1;

[0027] The feeding mechanism includes an electric cylinder 4, a one-way gripper 5 and a fixed-length regulator 6. Among them, the electric cylinder 4 is symmetrically fixed on the support 3, the support 3 is fixed on the base plate 1, and the support 3 is located on the side of the cutting machine.

[0028] In this embodiment, the one-way gripper 5 includes a U-shaped seat 51. The U-shaped seat 51 is fixed at the end of the electric cylinder 4, and a swing plate 52 is movably connected in the U-shaped seat 51.

[0029] In this embodiment, the end of the swing plate 52 is connected to the U-shaped seat 51 through a pin shaft, so that the swing plate 52 can swing inside the U-shaped seat 51, and a tension spring 53 is provided between the U-shaped seat 51 and the swing plate 52.

[0030] In this embodiment, the fixed-length regulator 6 includes a fixing plate 61 fixed on the U-shaped seat 51 and a limit plate 63 fixed on the electric cylinder 4, and a sliding rod 62 is movably connected inside the limit plate 63.

[0031] In this embodiment, one end of the sliding rod 62 penetrates through the limit plate 63 and is fixedly connected to the fixing plate 61. A baffle 64 is sleeved on the other end of the sliding rod 62. The feeding length is controlled by adjusting the position of the baffle 64 on the sliding rod 62, and a locking knob 65 is in threaded cooperation at the connection between the sliding rod 62 and the baffle 64.

[0032] In this embodiment, the sliding rods 62 are respectively slidably connected to the limiting plate 63 and the baffle plate 64, so that the sliding rods 62 can move following the U-shaped seat 51, and a contact switch 66 is embedded on one side of the baffle plate 64 close to the limiting plate 63.

[0033] By adopting the above technical solution, the U-shaped seat 51 is pushed by the electric cylinder 4 to move. When approaching the cutting machine, due to the inclination of the swing plates 52, the swing plates 52 on both sides will approach the titanium alloy welded pipe 7 to be processed, so as to clamp the titanium alloy welded pipe 7 to be processed. When moving away from the cutting machine, due to the inclination of the swing plates 52, the swing plates 52 will slide on the surface of the titanium alloy welded pipe 7 to be processed, completing the feeding action of the titanium alloy welded pipe 7 to be processed, and adjusting the position of the baffle plate 64 on the sliding rod 62 can adjust the cutting size at any time.

[0034] In this embodiment, one end of the tension spring 53 is fixed to the swing plate 52, and the other end is fixed to the U-shaped seat 51, applying a pulling force to the swing plate 52 to make the swing plate 52 fit against the side surface of the titanium alloy welded pipe 7 to be processed.

[0035] In this embodiment, the titanium alloy welded pipe 7 to be processed is also placed on the support 3, and the end of the titanium alloy welded pipe 7 to be processed extends into the cutting machine 2.

[0036] In this embodiment, a card slot 54 is formed on one side of the swing plate 52, and the titanium alloy welded pipe 7 to be processed is located in the card slot 54, increasing the contact area and preventing unnecessary sliding when the swing plate 52 clamps the titanium alloy welded pipe 7 to be processed.

[0037] In this embodiment, the side of the swing plate 52 away from the U-shaped seat 51 is inclined towards the side close to the cutting machine 2, ensuring two states when the swing plate 52 moves, so as to drive the titanium alloy welded pipe 7 to be processed to move in one direction.

[0038] In this embodiment, the cutting machine 2 includes a cutting seat, a support rod and a cutting assembly fixedly connected to the bottom plate 1. One end of the support rod is welded to the cutting seat, and the other end of the support rod is movably connected to the cutting assembly through a pin shaft.

[0039] In this embodiment, the cutting assembly includes a housing movably connected to the support and a driving motor fixed on one side of the housing, and a saw blade is arranged inside the housing. One side of the driving motor penetrates the housing and contacts the saw blade, and the titanium alloy welded pipe 7 to be processed is cut by the saw blade rotating at a high speed.

[0040] In this embodiment, the surface of the support 3 is horizontally arranged with the surface of the cutting seat in the cutting machine 2, preventing obstruction when the titanium alloy welded pipe 7 to be processed moves, and one end of the titanium alloy welded pipe 7 to be processed is located on the cutting seat.

[0041] In this embodiment, the end of the locking knob 65 penetrates through the baffle 64 and fits against the side surface of the sliding rod 62 to fix the position of the baffle 64 on the sliding rod 62.

[0042] In this embodiment, an arc-shaped groove is provided on one side of the baffle 64 close to the electric cylinder 4, and the baffle 64 is slidably engaged with the electric cylinder 4 through the arc-shaped groove to prevent the baffle 64 from tilting when fixed, resulting in the contact switch 66 being unable to contact the limit plate 63.

[0043] In this embodiment, the drive motor inside the cutting machine 2 is electrically connected to an external power source through a wire, and the external power source supplies power to the drive motor.

[0044] In this embodiment, the electric cylinder 4 is electrically connected to an external power source through a wire, and a feed switch and a contact switch 66 are also connected in series on the wire, and a return switch is connected in parallel with the feed switch and the contact switch 66.

[0045] Specifically, both the feed switch and the return switch are normally open switches, and the contact switch 66 is a normally closed switch.

[0046] Further, when the feed switch is pressed, the contact inside the feed switch changes from the open state to the closed state. At this time, the circuit is closed, and the external power source supplies power to the electric cylinder 4. The electric cylinder 4 drives the one-way gripper to move. When the contact switch 66 touches the limit plate 63, the contact inside the contact switch 66 changes from the closed state to the open state, the circuit is disconnected, and the external power source stops supplying power;

[0047] When the return switch is pressed, the direction of the current in the circuit is output in the reverse direction, and the external power source supplies reverse power to the electric cylinder 4 to make the one-way gripper of the electric cylinder 4 move in the reverse direction.

[0048] The working principle of the present utility model is as follows: When in use, first place the titanium alloy welding pipe 7 to be processed on the support 3, then adjust the position of the baffle 64 on the sliding rod 62 according to the required length of the titanium alloy pipe to be obtained, and then tighten the locking knob 65 to fix the position of the baffle 64. The electric cylinder 4 pushes the U-shaped seat 51 to move, and the tension spring 53 pulls the swing plate 52 to closely adhere to the side of the titanium alloy welding pipe 7 to be processed. When moving in the direction close to the cutting machine 2, due to the inclination of the swing plate 52, the swing plate 52 will be stuck on the outer side of the titanium alloy welding pipe 7 to be processed, driving the titanium alloy welding pipe 7 to be processed to move. As the sliding rod 62 moves, the sliding rod 62 will drive the contact switch 66 on the side of the baffle 64 to contact the limit plate 63. The contact switch 66 disconnects the power supply circuit of the electric cylinder 4, and the electric cylinder 4 stops operating. Then, the saw blade is moved downward through the movable connection between the support rod and the housing, and the drive motor drives the saw blade to move at high speed to cut the titanium alloy welding pipe 7 to be processed. During cutting, the electric cylinder 4 drives the one-way gripper 5 to move to the side away from the cutting machine 2. Due to the inclination of the swing plate 52, the swing plate 52 will slide on the side of the titanium alloy welding pipe 7 to be processed. After cutting is completed, the electric cylinder 4 pushes the one-way gripper 5 to move again, repeating the above process to complete the small-batch fixed-length cutting of the titanium alloy pipe, and the cutting size can also be adjusted at any time according to requirements.
