[0031] 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 belong to the scope of protection of the utility model.

Therefore, the above terms should not be understood as limiting the present invention.

[0033] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0034] like Figure 1-17The utility model provides a straight tube cutting mechanism, which is applied to a straight tube cutting machine. The straight tube cutting machine includes a frame 1, a feeding positioning mechanism 2 and a cutting mechanism 3 arranged on the frame 1 in sequence. The feeding positioning mechanism 2 includes a plurality of inclined feeding racks 21 and a plurality of guide rollers 22 arranged on one side of the feeding racks 21. The pipes are stored at the plurality of feeding racks 21. When the pipes are processed, the pipes are moved from the feeding racks 21 to the guide rollers 22.

[0035] The material cutting mechanism 3 includes a cutting component, a breaking component and a material receiving frame arranged in sequence. The breaking component includes a fixed seat 31 and a breaking seat 32 movably installed on one side of the fixed seat 31. The fixed seat 31 is provided with a fixed clamp 33, and the breaking seat 32 is provided with a breaking clamp 34. When the pipe is pre-cut by the cutting component and moved to the position of the breaking component, the breaking clamp 34 breaks the pipe at the pre-cut position.

[0036] Specifically, the staff stacks a number of pipes on a loading rack. When the pipes need to be loaded, a single pipe is moved from the loading rack to a number of guide rollers so that the pipes can move along the guide rollers. When the pipes move to the designated position of the cutting mechanism, the cutting component pre-cuts the position to be processed of the pipe, and does not completely cut off the processing position. Subsequently, the pre-cut position of the pipe is moved between the fixed clamp and the breaking clamp. At this time, the fixed clamp and the breaking clamp simultaneously clamp and fix the pre-cut position, and the pre-cut position is broken by moving the breaking seat, thereby achieving the purpose of chipless cutting.

[0037] The guide roller is provided with a V-shaped groove along the circumference, so that the pipe can be placed in the V-shaped groove for support.

[0038] In one embodiment of the present solution, the breaking seat is moved by controlling the movement of the breaking seat with an oil cylinder, and the breaking seat is coordinated with a guide track laid at the bottom of the breaking seat to ensure the stability of the breaking seat during the breaking process.

[0039] It is worth mentioning that the breakaway clamp and the fixed clamp are similar to the existing clamp structure, that is, they are composed of at least two oppositely arranged clamping blocks, and both the breakaway clamp and the fixed clamp are clamped or released by the control of the gas-liquid booster cylinder.

[0040] Preferably, the loading and positioning mechanism 2 also includes a backrest 23 arranged on one side of the loading rack 21 and a lift block 24 arranged on one side of the loading rack 21 and can be raised and lowered. The backrest 23 is located at the lower end of the loading rack 21, and the top surface of the lift block 24 is inclined.

[0041] Specifically, when a number of pipes are placed on the loading rack, the pipes roll down along the inclined loading rack and are uniformly stacked due to the limitation of the backrest. When one of the pipes needs to be taken out, the lifting block rises and lifts one of the pipes to rise synchronously, so that the pipe is freed from the limitation of the backrest, and then the pipe slides along the inclined position of the top surface of the lifting block to the position of the guide roller, so as to facilitate the loading of the pipe.

[0042] Among them, the lifting and lowering of the top material block is controlled by a cylinder.

[0043] Preferably, the loading and positioning mechanism 2 further comprises a guide plate 25 , on which a guide hole 26 is formed, and a guide sleeve 27 is arranged along the outer circumference of the guide hole 26 , and when the pipe moves along the plurality of guide rollers 22 , it passes through the position of the guide sleeve 27 .

[0044] Specifically, when the pipe moves along a plurality of guide rollers, one end of the pipe needs to pass through a guide hole on a guide plate for guide limiting to ensure the accuracy of the position of the pipe in subsequent processing steps such as cutting and breaking.

[0045] Furthermore, due to the provision of the guide sleeve, when the pipe passes through the guide hole, the guide sleeve can prevent friction between the pipe and the guide plate, thereby reducing the possibility of damage to the pipe or parts.

[0046] Among them, the guide sleeve is made of nylon.

[0047] Preferably, the loading and positioning mechanism 2 also includes a movably installed pushing seat 28 and a supporting block 29 arranged on one side of the pushing seat 28. One side of the pushing seat 28 has a guide rod 210. The supporting block 29 is movably installed on the guide rod 210, and an elastic member 211 is connected between the supporting block 29 and the guide rod 210. One end of the pipe is placed on the supporting block 29.

[0048] Specifically, when the pipe is moved from the loading rack to the guide roller, one end of the pipe is placed on the supporting block, and the supporting block pushes the end of the pipe to move by moving the pushing seat, thereby facilitating the movement control of the pipe.

[0049] In particular, when the pipe moves to the subsequent limit block so that the other end of the pipe is restricted to position the pipe as a whole, if the supporting block still moves forward a certain distance with the pushing seat, the supporting block will compress the elastic part and move a certain distance along the guide rod to achieve the purpose of buffering and anti-collision, and in the subsequent process of the pushing seat moving and resetting, the supporting block can be pushed to reset by the elastic part.

[0050] Wherein, the elastic member adopts a spring structure.

[0051] In one embodiment of the present solution, the movement of the pusher seat is controlled by a servo motor in conjunction with a gear rack transmission.

[0052] It is worth mentioning that a V-shaped groove is provided on the support seat, and one end of the pipe is placed on the V-shaped groove to facilitate the limiting support of the pipe end.

[0053] Preferably, the guide plate 25 has a positioning component on the side away from the guide roller 22, the positioning component includes a positioning seat 212, a limit block 213 movably installed on one side of the positioning seat 212, the end of the limit block 213 has a sensing block 214 corresponding to the pipe, and the side of the positioning seat 212 close to the limit block 213 has an inclined slide rail 215, and the limit block 213 moves along the inclined slide rail 215.

[0054] Specifically, after the pushing seat pushes the pipe through the guide plate, the end of the pipe will contact and rest against one end of the limit block, so that the sensing block is triggered, which means that the pipe moves to the specified position. At this time, the limit block moves and resets relative to the positioning seat. Since the slide rail is inclined, when the limit block is reset along the slide rail, the surface of the limit block will directly move away from the end of the pipe, avoiding sliding friction between the surface of the limit block and the pipe end, which will cause the pipe to move horizontally. After the limit block is reset, the pipe can be processed and moved through subsequent processing parts.

[0055] The sensing block adopts a contact sensor, and the inclination angle of the slide rail is 5°.

[0056] In one embodiment of the present solution, the movement of the limit block is controlled by a cylinder.

[0057] Preferably, the cutting component includes a movably installed feeding platform 35, a cutting seat 36 arranged on the feeding platform 35, and a through hole 37 penetrating the cutting seat 36. The cutting seat 36 is provided with a plurality of positioning blocks 38 along the periphery of the through hole 37. The positioning blocks 38 can move radially along the through hole 37 relative to the cutting seat 36. Positioning wheels 39 are connected to the positioning blocks 38, and a cutting knife 310 is arranged on the periphery of one of the positioning wheels 39.

[0058] Specifically, after the pipe is initially positioned by the positioning component, the limit block is reset to make room for the pipe to move, and then the feeding platform moves toward the position of the pipe, and allows the end of the pipe to pass through the through-hole position. At this time, the pipe is fixed to ensure that the position of the pipe relative to the cutting knife is sufficiently stable and accurate. Then, several positioning blocks simultaneously approach the position of the pipe along the radial direction of the through-hole, so that multiple positioning wheels limit and support the outer periphery of the pipe's processing position, and facilitate the stability of the cutting knife when pre-cutting the pipe's processing position.

[0059] The movement of the feeding platform is controlled by a servo motor in combination with a gear rack transmission, and a guide rail is laid at the bottom of the feeding platform so that the feeding platform can move along the guide rail.

[0060] It is worth mentioning that this solution can be used with high-precision sensors to accurately locate and calculate the length of the pipe when feeding and cutting the pipe, so that the same raw material pipe can be cut into a variety of products of different lengths, minimizing the length of the tail material and avoiding waste. Products of different lengths can also be classified and collected into different subsequent material receiving frames.

[0061] Preferably, a support seat 311 is provided on the feeding platform 35 , and the cutting seat 36 is rotatably mounted on the support seat 311 . A driving sleeve 312 is axially movable mounted on the outside of the cutting seat 36 , and the driving sleeve 312 is wedge-matched with one side of the positioning block 38 .

[0062] Specifically, after multiple positioning wheels and cutting knives are in place, the cutting seat rotates relative to the supporting seat, so that the cutting seat can drive the cutting knife to rotate circumferentially along the outer circumference of the position to be processed of the pipe, and then the pipe is pre-cut by the cutting knife. During the cutting process, the cutting depth of the cutting knife can be increased by moving the positioning block closer to the pipe.

[0063] The rotation of the cutting seat relative to the supporting seat is controlled by a servo motor in conjunction with a synchronous pulley.

[0064] It is worth mentioning that when it is necessary to control the positioning block to move along the radial direction of the through hole, the driving sleeve is moved along the axial direction of the cutting seat, and the inclined wedge cooperation between the driving sleeve and the positioning block is combined, so that the positioning block can be driven to move when the driving sleeve moves, thereby accurately controlling the movement of the positioning wheel and the cutting knife.

[0065] In one embodiment of the present scheme, the movement of the drive sleeve is driven by a servo motor, and it is worth mentioning that the output end of the servo motor is provided with a connecting part such as a bearing or a roller at the connection position with the drive sleeve, so that when the drive sleeve rotates circumferentially with the cutting seat, only the connecting parts such as the bearing or the roller rotate, so that the servo motor will not rotate synchronously with the cutting seat while maintaining control over the drive sleeve.

[0066] Preferably, a feeding seat 313 is also provided on the feeding platform 35, and a feeding clamp 314 is provided on the feeding seat 313, and the feeding clamp 314 is arranged corresponding to the through hole 37; an auxiliary clamp component is provided on the frame 1, and the auxiliary clamp component includes an auxiliary clamp 315, and the auxiliary clamp 315 is arranged corresponding to the feeding clamp 314.

[0067] Specifically, after the pipe is initially positioned by the positioning component, the feeding platform moves to the position of the pipe. When the pipe needs to be pre-cut at the processing position, the feeding clamp and the auxiliary clamp simultaneously clamp the pipe to ensure the stability of the pipe during the pre-cutting process. After the pre-cutting is completed, the auxiliary clamp is released, and the pipe is pulled toward the breaking component through the feeding clamp and the feeding platform.

[0068] Among them, the feeding clamp and the auxiliary clamp are both clamped or loosened by gas-liquid booster cylinders, and the feeding clamp and the auxiliary clamp are similar to the existing clamp structure, that is, they are composed of at least two clamping blocks arranged oppositely.

[0069] Preferably, the material receiving rack includes a flap 316 rotatably mounted on the side of the breaking seat 32 away from the fixed seat 31 , and a material receiving frame 317 disposed on both sides of the flap 316 . When the breaking clamp 34 breaks the pipe, the pipe falls onto the flap 316 .

[0070] Specifically, after the breaking clamp breaks the pre-cut position of the tube, the broken tube part falls onto the flap, and the flap rotates and tilts toward the receiving frame on one side, so that the tube on the flap falls to the corresponding receiving frame for collection.

[0071] Among them, a cylinder is connected to one side of the bottom of the flap. When the output end of the cylinder is extended, the connection side of the flap rises. When the output end of the cylinder is contracted, the connection side of the flap falls, so as to control the rotation of the flap.

[0072] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
