Description

Technical Field

[0001] The invention relates to the technical field of pipe cutting equipment, in particular to a pipe-making flying saw equipment and a flying saw method for forming ultra-thin steel pipes. Background Art

[0002] During the actual installation of pipes, the length and size of the pipes will be limited due to different equipment environment requirements, so the pipes need to be cut to form short pipes of preset length. At present, steel pipe cutting equipment generally adopts a single steel pipe cutting method, and the specified length of a single pipe is transported to the bottom of the cutting equipment, so that the cutting equipment cuts the single pipe into multiple short pipes. Since only a single pipe can be cut at a time, the cutting efficiency of the cutting equipment is low. In addition, the prior art also has a conveying mechanism that arranges multiple pipes neatly, and then conveys the specified lengths of multiple pipes to the bottom of the cutting equipment at the same time. However, after the cutting is completed, these pipes will be separated from the original arrangement, directly fall and scatter all over the ground, making the subsequent bundling work difficult, thereby affecting the overall work efficiency.

[0014] A further solution is that the conveying fixture further comprises a first fixture cylinder and a first fixture pressing plate; the cutting fixture further comprises a second fixture cylinder and a second fixture pressing plate; the pulling fixture further comprises a third fixture cylinder and a third fixture pressing plate;

[0015] The first clamp pressing plate, the second clamp pressing plate and the third clamp pressing plate are used to press down the multiple steel pipes stacked in the corresponding receiving grooves of the first clamp bottom mold, the second clamp bottom mold and the third clamp bottom mold respectively.

[0019] A further solution is that a movable pushing mechanism is provided on the pulling clamp, and the movable pushing mechanism includes a movable pushing cylinder, which is used to drive a movable pushing plate to move in a direction perpendicular to the central axis of the steel pipe. The contact surface between the movable pushing plate and the steel pipe is an inclined surface, and the accommodating groove is trapezoidal.

[0020] A further solution is that the material pulling mechanism comprises a material pulling frame, and a material receiving frame is arranged on a side of the material pulling frame away from the movable material pushing mechanism.

[0021] A further solution is that a fixed pushing mechanism is provided at one end of the pulling mechanism close to the feeding mechanism, and the fixed pushing mechanism includes a fixed pushing cylinder, and the output end of the fixed pushing cylinder is fixedly connected to a fixed pushing plate, and the contact surface between the fixed pushing plate and the steel pipe is also an inclined surface.

[0023] According to a second aspect of the present invention, a flying saw method for forming an ultra-thin steel pipe is provided. The method is based on the above-mentioned device and specifically comprises:

[0024] Step S1, stacking a plurality of steel pipes neatly in the receiving grooves of the first clamp bottom mold and the third clamp bottom mold;

[0025] Step S2, using a cutting mechanism to cut the front ends of the plurality of steel pipes flat;

[0030] Compared with the prior art, the present invention has the following beneficial effects: (1) the receiving groove of the present invention can simultaneously stack multiple steel pipes, and has excellent size adaptability, and can be suitable for steel pipes of different sizes. When the knife holder cylinder drives the knife holder slide to move downward, the saw blade can simultaneously cut multiple steel pipes, and the cutting efficiency is high;

[0032] (3) After the steel pipe is cut, the movable pushing mechanism can follow the movement of the pulling clamp to ensure that the movable pushing mechanism and the fixed pushing mechanism can be accurately positioned at the two ends of the cut steel pipe. At this time, the movable pushing mechanism and the fixed pushing mechanism act simultaneously. Since the receiving groove is trapezoidal, the contact surface between the movable pushing plate and the fixed pushing plate and the steel pipe is also an inclined surface, and there is no other structure inside the receiving groove. During the pushing process, the steel pipe can slide outward along the inclined surface and finally be smoothly pushed out of the receiving groove and fall onto the receiving rack. Although the cut steel pipes are also scattered at this time, these steel pipes will not be in a messy state. Workers can easily bundle and organize these cut short pipes without spending extra time and energy to deal with messy steel pipes. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0052] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0054] See also Figure 1-Figure 5 The present invention provides a flying saw device for forming ultra-thin steel pipes, comprising a feeding mechanism 1, a cutting mechanism 2 and a pulling mechanism 3. The feeding mechanism 1 comprises a feeding frame 103, the pulling mechanism 3 comprises a pulling frame 303, the feeding frame 103 and the pulling frame 303 are connected to each other, and the cutting mechanism 2 is arranged at one end of the feeding mechanism 1 close to the pulling mechanism 3.

[0055] A first servo motor 101 is installed on the feeding frame 103. The output end of the first servo motor 101 is connected to a first driving wheel through a reducer, and the first driving wheel is connected to a first driven wheel through a first synchronous belt 102. The first synchronous belt 102 is used to drive a conveying clamp 106 to move forward, and the conveying clamp 106 is used to clamp multiple steel pipes at the same time. Specifically, the conveying clamp 106 includes a first clamp bottom plate, on which a conveying clamp support plate 1062 and a first clamp bottom mold 1061 are installed. The first clamp bottom mold 1061 is provided with a receiving groove for stacking multiple steel pipes at the same time. A first clamp cylinder 1063 is installed on the upper end of the conveying clamp support plate 1062. The output end of the first clamp cylinder 1063 is fixedly connected to the first clamp pressure plate 1064. The first clamp cylinder 1063 drives the first clamp pressure plate 1064 to move downward, and cooperates with the first clamp bottom mold 1061 to limit the steel pipe, so that multiple steel pipes stacked on the first clamp bottom mold 1061 can be clamped at the same time. The first fixture bottom plate is connected to the first synchronous belt 102, and the two ends of the lower surface of the first fixture bottom plate slide with the feeding guide rail 104 through sliders. The feeding guide rail 104 will not hinder the first synchronous belt 102 from driving the conveying fixture 106 to move forward, and at the same time plays a role in supporting the weight of the conveying fixture 106.

[0056] The cutting mechanism 2 includes a tool rest seat 201, which is mounted on the feeder frame 103. A tool rest cylinder 202 and a tool rest guide rail 203 are mounted on the tool rest seat 201. The output end of the tool rest cylinder 202 is fixedly connected to a tool rest slide 204, which is slidably matched with the tool rest guide rail 203. A tool rest motor 205 and a saw blade 206 are mounted on the tool rest slide 204. The tool rest motor 205 drives the saw blade 206 to rotate through a transmission mechanism. When the tool rest cylinder 202 drives the tool rest slide 204 to move downward, the saw blade 206 will contact the steel pipe, so that multiple steel pipes can be cut at the same time, and the cutting efficiency is high.

[0057] It should be noted that the transmission mechanism can be mutually meshing bevel gears or a worm gear; it can also be other transmission mechanisms, which are not specifically limited in this application and are all within the protection scope of this application.

[0058] Two cutting fixtures 108 are arranged on the feeding frame 103 located at the cutting mechanism 2, and the saw blade 206 is used to cut the steel pipe between the two cutting fixtures 108. Figure 4 As shown, the cutting fixture 108 includes a second fixture base plate installed on the upper surface of the feed frame 103, a second fixture bottom mold 1085 is installed on the second fixture base plate, guide sleeves 1081 are arranged on both sides of the second fixture bottom mold 1085, a second fixture cylinder 1083 is installed on the lower surface of the second fixture base plate, the output end of the second fixture cylinder 1083 is fixedly connected to a cylinder push plate, four guide columns 1082 are installed on the cylinder push plate, and a second fixture pressure plate 1084 is fixedly connected to the top of every two guide columns 1082, and the outer surface of the guide column 1082 is slidably matched with the inner surface of the guide sleeve 1081. The second clamp bottom die 1085 is also provided with a receiving groove for stacking multiple steel pipes at the same time. The second clamp cylinder 1083 can simultaneously drive the second clamp pressure plates 1084 corresponding to the two cutting clamps 108 to move downward, and cooperate with the second clamp bottom die 1085 to limit the steel pipe, so that the multiple steel pipes stacked in the receiving groove can be clamped at the same time. Since the cutting clamp 108 is set at the cutting mechanism 2, the steel pipe will not shake during the cutting process, which is conducive to obtaining a smooth cutting surface.

[0059] A second servo motor 301 is installed on the material pulling frame 303, and the output end of the second servo motor 301 is connected to a second driving wheel through a reducer, and the second driving wheel is connected to a second driven wheel through a second synchronous belt 302. The second synchronous belt 302 is used to drive the material pulling clamp 305 to move forward, and the material pulling clamp 305 can also clamp multiple steel pipes at the same time. Specifically, the material pulling clamp 305 includes a third clamp bottom plate, on which a material pulling clamp support plate 3052 and a third clamp bottom mold 3051 are installed. The third clamp bottom mold 3051 is also provided with a receiving groove for stacking multiple steel pipes at the same time. A third clamp cylinder 3053 is installed on the upper end of the material pulling clamp support plate 3052. The output end of the third clamp cylinder 3053 is fixedly connected to a third clamp pressure plate 3054. The third clamp cylinder 3053 drives the third clamp pressure plate 3054 to move downward, and cooperates with the third clamp bottom mold 3051 to limit the steel pipe, so that multiple steel pipes stacked on the third clamp bottom mold 3051 can also be clamped at the same time. The third clamp base plate is connected to the second synchronous belt 302, and the two ends of the lower surface of the third clamp base plate slide with the material pulling guide rail 304 through sliders. The material pulling guide rail 304 will not hinder the second synchronous belt 302 from driving the material pulling clamp 305 to move forward, and at the same time plays a role in supporting the weight of the material pulling clamp 305.

[0060] It should be noted that the material pulling clamp 305 is used to receive the multiple steel pipes delivered by the feeding mechanism 1, and through the cooperation between the third clamp pressure plate 3054 and the third clamp bottom mold 3051, the multiple steel pipes can be clamped, so that the second servo motor 301 can drive the material pulling clamp 305 to move forward a preset distance. When the saw blade 206 cuts the steel pipe, the material pulling clamp 305 plays a role in supporting the steel pipe, and the steel pipe will not fall down and will not be scattered on the ground, which is convenient for bundling the cut short pipes, so as not to affect the overall work efficiency; and in the process of the saw blade 206 cutting the steel pipe, the material pulling clamp 305 plays a role in supporting the front end of the steel pipe, which is further conducive to improving the flatness of the cutting surface.

[0061] Preferably, the material pulling fixture 305 is provided with a movable material pushing mechanism 5, and the second servo motor 301 can drive the material pulling fixture 305 to move forward and at the same time drive the movable material pushing mechanism 5 to move forward. The movable material pushing mechanism 5 includes a movable material pushing cylinder 501, which is installed on the material pulling fixture support plate 3052 through the fixture side plate, and a movable material pushing guide rail 504 is installed on the material pulling fixture support plate 3052, and a movable material pushing plate 503 is slidably matched on the movable material pushing guide rail 504, and two movable material pushing plates 503 are connected together through a connecting plate 502, and the output end of the movable material pushing cylinder 501 is connected to the connecting plate 502. The movable material pushing cylinder 501 is used to drive the movable material pushing plate 503 to move in a direction perpendicular to the central axis of the steel pipe, and the contact surface between the movable material pushing plate 503 and the steel pipe is an inclined surface, and the above-mentioned accommodating grooves are all trapezoidal, preferably isosceles trapezoidal. In addition, a fixed material pushing mechanism 4 is provided at one end of the material pulling mechanism 3 close to the material feeding mechanism 1, and the fixed material pushing mechanism 4 includes a fixed material pushing cylinder 401, and the output end of the fixed material pushing cylinder 401 is fixedly connected to a fixed material pushing plate 402, and the contact surface between the fixed material pushing plate 402 and the steel pipe is also an inclined surface. The fixed material pushing plate 402 is slidably matched with a fixed material pushing guide rail 403 through a slider, and the fixed material pushing guide rail 403 is installed at one end of the material pulling frame 303 close to the material feeding frame 103. A material receiving frame 6 is provided on the side of the material pulling frame 303 away from the movable material pushing mechanism 5. After the steel pipe is cut, since the movable pushing mechanism 5 can move with the pulling clamp 305, it is ensured that the movable pushing mechanism 5 and the fixed pushing mechanism 4 can be accurately positioned at the two ends of the cut steel pipe. At this time, the movable pushing mechanism 5 and the fixed pushing mechanism 4 act simultaneously. Since the receiving groove is trapezoidal, the contact surfaces of the movable pushing plate 503 and the fixed pushing plate 402 with the steel pipe are also inclined surfaces, so that during the pushing process, the steel pipe can slide outward along the inclined surface, and finally be smoothly pushed out of the receiving groove and fall onto the receiving rack 6. Although the cut steel pipes are also scattered at this time, these steel pipes will not be in a messy state, and workers can easily bundle and organize these cut short pipes without spending extra time and energy to deal with messy steel pipes.

[0062] Preferably, Figure 5 As shown, a receiving water bucket 7 is installed on the feeder frame 103 at the cutting fixture 108, and the receiving water bucket 7 includes an inclined plate 703 and a feed port 701 for receiving cooling water and material heads; a filter hole 702 is opened on the inclined plate 703, and a baffle 704 is installed at the bottom and side of the inclined plate 703. After the cutting mechanism 2 cuts the front and rear ends of the multiple steel pipes flat, the cut material heads will fall onto the inclined plate 703. In addition, the water used to clean the debris during the cutting process will also fall onto the inclined plate 703, and after being filtered through the filter hole 702, it will fall below the inclined plate 703, thereby being separated from the cut material heads.

[0063] For the preferred option, please continue to read Figure 1-Figure 3 A rolling shaft 105 is provided at one end of the feeding frame 103 away from the pulling frame 303, and both ends of the rolling shaft 105 are rotatably connected to the feeding frame 103 through bearing seats. A feeding clamping mechanism 107 is provided at one end of the feeding frame 103 close to the pulling frame 303, and the feeding clamping mechanism 107 includes a clamping frame 1072 installed on the feeding frame 103, and a clamping cylinder 1071 is installed on the clamping frame 1072. A clamping support plate 1073 is fixedly connected to the output end of the clamping cylinder 1071, and a clamping shaft 1074 is rotatably connected to the clamping support plate 1073. The clamping shaft 1074 can prevent the steel pipe from shaking or deflecting during cutting. The rolling shaft 105 mainly plays a role in preliminary support and guidance of the steel pipe. Before the steel pipe is fed into the cutting area, the rolling shaft 105 can ensure that the steel pipe can move smoothly and smoothly, and prepare for the subsequent clamping and cutting work.

[0064] It should be noted that a feeding and clamping mechanism 107 is provided at one end of the feeding rack 103 close to the pulling rack 303. In order to prevent the clamping rack 1072 of the feeding and clamping mechanism 107 from hindering the steel pipe from falling onto the receiving rack 6, after the cutting mechanism 2 cuts off the steel pipe, the pulling mechanism 3 can move the steel pipe forward a short distance so that the end of the steel pipe moves to the front of the clamping rack 1072.

[0065] The present invention also provides a flying saw method for forming an ultra-thin steel pipe. The method is based on the above-mentioned device and specifically comprises:

[0066] Step S1, stacking a plurality of steel pipes neatly in the receiving grooves of the first clamp bottom mold 1061 and the third clamp bottom mold 3051;

[0067] Step S2, using the cutting mechanism 2 to cut the front ends of the plurality of steel pipes flat;

[0068] It should be noted that, during the process of cutting the steel pipe by the cutting mechanism 2, at least the cutting fixture 108 is required to press the steel pipe tightly so that the steel pipe will not shake during the cutting process, which is conducive to obtaining a smooth cutting surface.

[0069] Step S3, the front end of the cut steel pipe is transported to the material pulling fixture 305 through the feeding mechanism 1;

[0070] In the process of the feeding mechanism 1 conveying the front end of the cut steel pipe to the pulling clamp 305, the conveying clamp 106 is needed to press the steel pipe so that the feeding mechanism 1 can drive the steel pipe with the front end cut forward. When the feeding mechanism 1 conveys the front end of the cut steel pipe to the pulling clamp 305, the feeding mechanism 1 controls the conveying clamp 106 to return to the initial position.

[0071] Step S4, driving the steel pipe forward by a preset distance through the pulling mechanism 3;

[0072] In the process of the pulling mechanism 3 driving the steel pipe to move forward a preset distance, the pulling clamp 305 is required to press the steel pipe tightly;

[0073] Step S5, using the cutting mechanism 2 to cut the middle parts of the plurality of steel pipes, and arranging the plurality of steel pipes obtained by cutting;

[0074] When the cutting mechanism 2 cuts off the steel pipe, the material pulling clamp 305 supports the steel pipe, and the steel pipe will not fall down and scatter on the ground, which makes it convenient to bundle the cut short pipes and does not affect the overall work efficiency. Moreover, during the process of the saw blade 206 cutting the steel pipe, the material pulling clamp 305 supports the front end of the steel pipe, which is further beneficial to improve the flatness of the cutting surface.

[0075] Step S6, repeat steps S3-S5 until the ends of the multiple steel pipes are also cut flat, so that each steel pipe is cut into multiple steel pipes of the same length.

[0076] It should be noted that after the cut short tube is separated from the material pulling fixture 305 , the material pulling mechanism 3 needs to control the material pulling fixture 305 to return to the initial position, so as to continue to receive the steel tube delivered by the feeding mechanism 1 .
