Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe production equipment, in particular to a buffer device for flying saw cutting steel pipes. Background Art

[0002] The flying saw is a flying saw machine, which is one of the key equipment on the steel pipe production line. During the high-speed production process of the steel pipe, after it reaches a certain length, the flying saw plays an important role in the high-precision cutting of the steel pipe. The operation process of the flying saw is synchronized with the steel pipe. During the sawing process, the saw blade will rotate around the saw axis and move at the same speed as the steel pipe, thereby ensuring that the cross section of the cut is straight. After the steel pipe reaches the required length, the high-speed rotating saw blade on the flying saw is pressed against the steel pipe under the action of the falling saw cylinder to cut the steel pipe. The saw carriage of the existing flying saw machine needs to move with the steel pipe. After the steel pipe is cut, the cut end of the steel pipe will bend downward under the action of its own gravity due to the sudden loss of limit at the cut end, which may collide with the saw carriage of the flying saw machine, causing the cut end of the steel pipe to deform or bump, which is not conducive to the subsequent high-precision processing of the steel pipe. Utility Model Content

[0003] In view of this, the utility model aims to propose a buffer device for flying saw cutting steel pipes, so as to solve the problem that when the existing flying saw machine is cutting steel pipes, the cut end of the steel pipe is easily collided with the saw carriage of the flying saw machine, causing the cut end of the steel pipe to deform or bump, thereby affecting the subsequent steel pipe processing.

[0006] Furthermore, an inclined portion for guiding the steel pipe to enter the second connecting member is provided at one end of the first connecting member facing the second connecting member.

[0007] Furthermore, the first connecting member is provided with a sliding block, and the second connecting member is provided with a sliding groove that slidably cooperates with the sliding block.

[0009] Furthermore, at least four rollers are correspondingly arranged on the left and right sides of the sliding block.

[0010] Furthermore, the guide plates on the left and right sides of the first connecting member and the second connecting member are both arranged in an inverted "eight" shape.

[0011] Furthermore, the buffer lifting seat, the guide plate, the first connecting member, and the second connecting member are all provided with buffer pads.

[0012] Furthermore, the buffer lifting seat adopts a spring shock-absorbing seat.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] A buffer device for flying saw cutting steel pipe, such as Figures 1 to 4As shown, it includes a mounting frame 1, and a buffer lifting seat 2 arranged in a stepped shape on the mounting frame 1, at least two buffer lifting seats 2 are arranged at intervals, and two adjacent buffer lifting seats 2 are connected by a connecting assembly; the connecting assembly includes a first connecting member 4 and a second connecting member 6, the first connecting member 4 is slidably mounted on the second connecting member 6, and the first connecting member 4 and the second connecting member 6 are respectively rotatably connected to the lifting ends of the corresponding buffer lifting seat 2; a pair of guide plates 5 are correspondingly provided on the left and right sides of the first connecting member 4 and the second connecting member 6, and there is an accommodating gap between the pair of guide plates 5 corresponding to the left and right sides of the second connecting member 6 to match the first connecting member 4.

[0027] Exemplarily, two, three or more buffer lift seats 2 can be arranged at intervals. A person skilled in the art can arrange multiple stepped buffer lift seats 2 according to the height difference between the flying saw and the subsequent conveyor belt, thereby realizing multi-level buffering of the cut end of the steel pipe, avoiding collision between the cut end of the steel pipe and the saw carriage of the flying saw, thereby protecting the cut end of the steel pipe and facilitating the subsequent processing of the steel pipe. Among them, one end of the first connecting member 4 is slidably mounted on the second connecting member 6, and the other end is rotatably mounted on the telescopic end of the upper buffer lift seat 2, one end of the second connecting member 6 is slidably connected to one end of the first connecting member 4, and the other end is rotatably mounted on the telescopic end of the lower buffer lift seat 2. By connecting two adjacent buffer lift seats 2 using a connecting assembly, the steel pipe can stably fall from the upper buffer lift seat 2 to the lower buffer lift seat 2 under the limitation and guidance of the connecting assembly, which is conducive to improving the stability of the steel pipe during the transmission process after cutting.

[0028] In actual application, the fixed end of the buffer lifting seat 2 can be fixed on the mounting frame 1 by screws, and the mounting frame 1 can also be fixed on the saw carriage or machine tool of the flying saw by screws. The technicians in this field can also choose a suitable way to install and fix the mounting frame 1 according to actual needs, so that the buffer lifting seat 2 on the mounting frame 1 can play a buffering role on the cut end of the steel pipe. By adopting multi-level buffering, when the steel pipe moves downward after cutting, the stepped buffer lifting seat 2 can avoid excessive impact force caused by excessive falling distance of the steel pipe at one time, thereby reducing the force and bounce amplitude of the steel pipe, which is conducive to preventing the displacement or damage of the steel pipe due to repeated bounce.

[0029] Optionally, the first connecting member 4 is provided with an inclined portion 9 at one end facing the second connecting member 6 for guiding the steel pipe into the second connecting member 6. Exemplarily, one end of the inclined portion 9 is fixed on the first connecting member 4, and the other end is arranged close to the second connecting member 6. By providing the inclined portion 9, a smooth transition between the first connecting member 4 and the second connecting member 6 can be achieved, so that the cut end of the steel pipe can smoothly pass through the first connecting member 4 and the second connecting member 6 to enter the next buffer lifting seat 2, and the steel pipe can be prevented from bouncing due to the bulge or misalignment between the first connecting member 4 and the second connecting member 6 during the movement.

[0030] In actual application, the buffer lifting seat 2 adopts a spring shock-absorbing seat, and the first connecting member 4 and the second connecting member 6 can be rotatably connected to the corresponding lifting end of the buffer lifting seat 2 through a rotating shaft. Those skilled in the art can also choose a suitable connection method according to actual needs, which will not be repeated here. By slidingly installing the first connecting member 4 on the second connecting member 6, and rotatably connecting the first connecting member 4 and the second connecting member 6 to the corresponding lifting end of the buffer lifting seat 2, when the steel pipe cut by the flying saw contacts the buffer lifting seat 2, and the buffer lifting seat 2 descends to provide buffer protection for the steel pipe, the first connecting member 4 or the second connecting member 6 can achieve adaptive adjustment of the angle by rotation, and the first connecting member 4 and the second connecting member 6 can also achieve adaptive adjustment of the length by relative sliding, which is conducive to ensuring the stability of the connection assembly when the buffer lifting seat 2 is raised and lowered.

[0031] Optionally, a slider 7 is provided on the first connecting member 4, and a slide groove 10 is provided on the second connecting member 6 to slide with the slider 7. Exemplarily, the slider 7 is fixed on the first connecting member 4, and the slider 7 cooperates with the slide groove 10 to improve the stability of the first connecting member 4 and the second connecting member 6 when sliding relative to each other.

[0032] In actual application, rollers 8 are provided on the slider 7 at positions corresponding to the position between the first connecting member 4 and the second connecting member 6, and at positions passing through the slide slot 10. Exemplarily, at least four rollers 8 are provided corresponding to the left and right sides of the slider 7, and the rollers 8 can be rotatably mounted on the slider 7 via a rotating shaft.

[0033] By arranging rollers 8 at the position between the first connecting member 4 and the second connecting member 6 and at the position passing through the slide groove 10, rotatable rollers 8 are arranged at the positions above and below the sliding block 7 corresponding to the second connecting member 6. By cooperating with the upper and lower groups of rollers, not only the sliding stability between the first connecting member 4 and the second connecting member 6 can be improved, but also the rollers 8 can convert the sliding friction between the first connecting member 4 and the second connecting member 6 into rolling friction, thereby improving the follow-up effect of the first connecting member 4 and the second connecting member 6 following the lifting and lowering of the buffer lifting seat 2, and the smoothness of the follow-up, which is conducive to the smooth passage of the steel pipe cutting section through the connecting assembly, and ensuring the buffering effect and reliability of this buffer device for continuous cutting of steel pipes.

[0034] Optionally, the guide plates 5 on the left and right sides of the first connecting member 4 and the second connecting member 6 are both arranged in an inverted "eight" shape. Exemplarily, the guide plates 5 can be fixed on the corresponding first connecting member 4 or the second connecting member 6. By adopting the inverted "eight" shape to arrange the guide plates 5, the guide plates 5 on the left and right sides of the first connecting member 4 and the second connecting member 6 can play a good guiding role for the steel pipe falling from the top, guiding the cut end of the steel pipe to move smoothly along the connecting assembly to the next buffer lifting seat 2, thereby improving the stability of the continuous cutting of the steel pipe moving on such a buffer device.

[0035] Optionally, a buffer pad 3 is provided on the buffer lifting seat 2, the guide plate 5, the first connecting member 4, and the second connecting member 6. Exemplarily, the buffer pad 3 can be made of rubber material, and the buffer pad 3 can be fixed to the corresponding buffer lifting seat 2, the guide plate 5, the first connecting member 4, and the second connecting member 6 by adhesive bonding. By providing the buffer pad 3, the possibility of damage to the cut end of the steel pipe due to collision can be further reduced.

[0036] The buffer device for cutting steel pipes with a flying saw described in the utility model has the advantages of simple structure, easy assembly and use, can be used in conjunction with a flying saw, and can play a good buffering and protective role on the end of the steel pipe after the flying saw is cut, preventing the cut end of the steel pipe from colliding with the saw carriage of the flying saw and causing damage, and facilitating the subsequent further processing of the steel pipe. By adopting multi-level buffering, during the downward movement of the steel pipe after the cutting is completed, the stepped buffer lifting seat can avoid excessive impact force caused by the excessive falling distance of the steel pipe at one time, thereby reducing the stress and bounce amplitude of the steel pipe, and preventing displacement or damage caused by repeated bounces of the steel pipe. At the same time, by connecting two adjacent buffer lifting seats with a connecting assembly, the steel pipe can stably fall into the next-level buffer lifting seat under the limitation and guidance of the connecting assembly, which is conducive to improving the stability of the steel pipe during the transmission process after cutting.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
