Abstract

The invention relates to the technical field of pipeline production and processing, and discloses a pipeline opening flattening machine for stainless steel pipe fitting production, which comprises a main body, and the front surface of the main body is fixedly connected with a control panel. When a moving rod continues to slide, a C-shaped frame drives a rotating plate to rotate and pushes arc-shaped plates to slide downwards, at the moment, the multiple arc-shaped plates can wrap and clamp the surface of a pipeline and push the pipeline to slide in the direction of a machining tool apron, the multiple arc-shaped plates extrude and wrap the surface of the pipeline, and the pipeline is driven to move, so that the machining efficiency of the pipeline is improved. The conditions that collision occurs when the machining tool apron makes contact with the pipeline and the pipeline slides backwards and deviates due to the fact that the feeding speed of the machining tool apron is too high when the opening is flattened can be reduced, and vibration marks on the machining surface occurring when the opening is flattened due to the fact that the multiple arc-shaped plates drive the pipeline to slide slightly can be relieved.

Description

Technical Field

[0001] The present invention relates to the technical field of pipe production and processing, and particularly to a pipe end-facing machine for stainless steel pipe fittings production. Background Art

[0002] A pipe end-facing machine can process a thin-walled stainless steel pipe into a weldable cut end without burrs. It cuts one end of the stainless steel pipe that needs to be processed to form a smooth cut, making the appearance of the pipe more beautiful and facilitating subsequent processing.

[0003] When deeply processing a pipe belt, it is necessary to perform end-facing treatment on the pipe. Generally, when performing end-facing, the feeding parameters are set on the control panel and then the end-facing work is carried out. When performing end-facing on a stainless steel pipe with a relatively thin thickness, due to the thin thickness and relatively smooth surface of the stainless steel, when the pipe is fixed by rotating the clamp with bolts and the feeding speed set by the staff is too fast, it is easy for the pipe to slide backward and shift after the tool contacts the pipe when the feeding speed of the tool is too fast, resulting in surface vibration marks or dimensional deviations during subsequent processing, affecting the processing quality.

[0040] The present invention has the following beneficial effects:

[0041] 1. In the present invention, when the feeding speed of the electric push rod driving the processing tool holder is too fast, it will impact the side wall of the moving rod. At this time, the elastic ball will push the rotating plate and the hollow plate to rotate to both sides. When the hollow plate rotates outwards, it will be stuck in the fixing ring inside the hollow frame. At the same time, when the rotating plate rotates, it will be stuck in the toothed plate. Then, when the moving rod continues to slide, it drives the rotating plate to rotate through the C-shaped frame and pushes the arc plate to slide downwards. At this time, multiple arc plates will wrap and clamp on the surface of the pipeline, and push the pipeline to slide towards the direction of the processing tool holder. Through the extrusion and wrapping of the pipeline surface by multiple arc plates and the driving of the pipeline movement, it can reduce the collision and the situation of the pipeline slipping and offsetting when the processing tool holder contacts the pipeline due to the too fast feeding speed during the flat mouth processing. Through the small sliding of the pipeline driven by multiple arc plates, it can relieve the situation of processing surface vibration marks or dimensional deviations during the flat mouth due to the sudden change of the feeding speed, thereby enhancing the stability of the pipeline during processing and the processing quality during the feeding flat mouth.

[0042] 2. In the present invention, when the arc plate squeezes the surface of the pipeline, the middle part of the corrugated plate will be squeezed when squeezing the elastic plate and then extend to both sides to form a stacked state. Subsequently, after the elastic plate is squeezed by the corrugated plate, its end will slide towards the side end of the corrugated plate on the inner wall of the arc plate and stretch the telescopic rod. When the end of the elastic plate slides towards the stacked side of the corrugated plate, it will generate a downward squeezing force on the stacked side of the elastic plate. The stacked parts on both sides of the two corrugated plates will squeeze the side wall of the pipeline after being squeezed by the elastic plate, thereby enhancing the friction force between the arc plate and the pipeline. By increasing the friction force, it can reduce the situation that it is difficult for the arc plate to drive the pipeline to slide due to the small friction force between the arc plate and the pipeline. At the same time, through the stacking at both ends of the corrugated plate, it can further enhance the stability of the pipeline during the flat mouth processing and improve the processing efficiency.

[0043] 3. In the present invention, when the arc plate drives the pipeline to slide, the sliding of the arc plate will push the middle part of the C-shaped frame two through the pushing plate to rotate on the side wall of the T-shaped rod, and drive the two sliding frames two to slide between the two right-angle blocks. When the two sliding frames two and the friction blocks slide relatively, they will quickly squeeze and friction the rectangular plate, thereby slowing down the feeding speed of the fixing ring driving the processing tool holder. When the processing tool holder moves rapidly in the reverse direction to the pipeline due to the too fast feeding speed, it can reduce the situation of chipping when the processing tool holder contacts the pipeline due to the fixed position of the pipeline surface after being stably clamped due to the too fast feeding speed, thereby achieving the purpose of slowing down the feeding speed during the flat mouth, enhancing the safety and processing quality during the flat mouth.

[0044] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] A limit assembly 32, the limit assembly 32 is installed on the side wall of the auxiliary assembly 31.

[0073] The placing member includes a hollow block 112 fixedly connected to the top of the main body 1. A telescopic shaft 113 is rotatably connected inside the hollow block 112. The top of the main body 1 is bolted with an upper clamping plate 111;

[0074] Wherein, one end of the telescopic shaft 113 close to the belt penetrates through the outer wall of the hollow block 112 and is sleeved and connected with the belt;

[0075] The clamping assembly 11 includes a machining tool holder 114 fixedly connected to one end of the telescopic shaft 113 away from the belt.

[0076] The telescopic member includes a sliding frame 121 rotatably connected to the outer surface of the telescopic shaft 113. A fixing ring 123 is fixedly connected to the outer surface of the sliding frame 121. Four rectangular plates are fixedly connected to the side wall of the fixing ring 123;

[0077] The sliding assembly 12 includes electric push rods 122 fixedly connected to the front and back of the sliding frame 121. One end of the electric push rod 122 close to the belt is fixedly connected to the side wall of the hollow block 112. First, rotate the upper clamping plate 111, and then place the pipe to be chamfered between the top of the main body 1 and the upper clamping plate 111. Then, initially fix the pipe by screwing the upper clamping plate 111. Then, start the motor 101. When the motor 101 is working, it will drive the telescopic shaft 113 to rotate through the belt.

[0078] A plurality of toothed rings are fixedly connected to the inner wall of the hollow frame 201;

[0079] The moving assembly 21 includes a plurality of moving rods 211 slidably penetrating through the side wall of the hollow frame 201. Two spring plates 212 are fixedly connected to the outer surface of the moving rod 211. One end of the spring plate 212 close to the hollow frame 201 is fixedly connected to the side wall of the hollow frame 201;

[0080] The elastic member includes a rotating plate 221 rotatably connected to one end of the moving rod 211 close to the hollow frame 201. A C-shaped frame 222 is rotatably connected to the outer surface of the rotating plate 221;

[0081] The flipping assembly 22 includes a hollow plate 223 slidably connected to the central axis of the C-shaped frame 222. One end of the hollow plate 223 close to the moving rod 211 is rotatably connected to the side wall of the moving rod 211;

[0082] Among them, two reset springs 224 are arranged on the top of the rotating plate 221, an elastic ball is fixedly connected between the two reset springs 224, and the reset spring 224 at the top is fixedly connected with the hollow plate 223;

[0083] Among them, the reset spring 224 at the bottom is fixedly connected with the side wall of the rotating plate 221. When the moving rod 211 is impacted, the impact force received by the moving rod 211 will be transmitted to the elastic ball. At this time, when the rotating plate 221 is impacted, the elastic ball will push the rotating plate 221 and the hollow plate 223 to rotate to both sides through the reset spring 224. When the hollow plate 223 rotates outwards, it will be stuck in the fixing ring inside the hollow frame 201.

[0084] The translation part includes a sliding rod 231 slidably connected between two rectangular grooves 202. An arc-shaped plate 232 is slidably connected to the outer surfaces of the two sliding rods 231, and the bottom of the arc-shaped plate 232 is open;

[0085] Among them, two bending springs are fixedly connected to the bottom of the arc-shaped plate 232, and the tops of the bending springs are fixedly connected to the inner wall of the hollow frame 201

[0086] The fitting assembly 23 includes two second rectangular grooves opened at the top of the arc-shaped plate 232, and a plurality of toothed plates 233 are fixedly connected to the top of the arc-shaped plate 232;

[0087] The extrusion part includes a corrugated plate 241 slidably connected at the opening of the arc-shaped plate 232. Two elastic plates 242 are arranged on the top of the corrugated plate 241, and the elastic plates 242 are rotatably connected inside the arc-shaped plate 232;

[0088] The deformation assembly 24 includes a telescopic rod 243 rotatably connected to the side wall of the elastic plate 242. The side of the telescopic rod 243 away from the elastic plate 242 is rotatably connected inside the second rectangular groove. At the same time, when the rotating plate 221 rotates, it will be stuck in the toothed plate 233. Then, when the moving rod 211 continues to slide, it will push the hollow plate 223 and the rotating plate 221. At this time, after the hollow plate 223 is blocked by the fixing ring, it will drive the rotating plate 221 to rotate through the C-shaped frame 222. When the rotating plate 221 rotates, it will push the arc-shaped plate 232 to slide downwards. At this time, multiple arc-shaped plates 232 will wrap and clamp on the surface of the pipeline. At the same time, when the rotating plate 221 rotates, it will push the pipeline towards the processing tool holder 114 through the arc-shaped plate 232.

[0089] The auxiliary assembly 31 includes a second C-shaped frame 311 rotatably connected to one end of the pushing plate 301 away from the arc-shaped plate 232. A second sliding frame 312 is slidably connected to the inner wall of the second C-shaped frame 311 close to the pushing plate 301, and a friction block 313 is fixedly connected inside the second sliding frame 312;

[0090] Among them, one end of two push plates 301 close to the arc plate 232 is rotatably connected to the side walls of two of the arc plates 232. A T-shaped rod is slidably connected inside the C-shaped frame two 311. One end of the T-shaped rod close to the hollow frame 201 is slidably connected to the side wall of the hollow frame 201. As Figure 4 shown, only the side walls of the two arc plates 232 at the top and bottom are rotatably connected to the push plates 301, while the left and right ones are not connected to the push plates 301. When the arc plate 232 drives the pipe to slide, the sliding of the arc plate 232 will push the middle part of the C-shaped frame two 311 through the push plate 301 to rotate on the side wall of the T-shaped rod. When the C-shaped frame two 311 rotates, it will drive the two sliding frames two 312 to slide between the two right-angle blocks 321.

[0091] On one side of the friction block 313 away from the push plate 301, there are two right-angle blocks 321. Connecting strips are fixedly connected to the top and bottom of the two arc plates 232; one end of the right-angle block 321 away from the friction block 313 is fixedly connected to an arc rod 322. One end of the arc rod 322 away from the right-angle block 321 is fixedly connected to the side wall of the hollow frame 201. After the stacked parts on both sides of the corrugated plate 241 are squeezed by the elastic plate 242, they will squeeze the side wall of the pipe, thereby enhancing the friction between the arc plate 232 and the pipe.

[0092] During use, first rotate the upper clamping plate 111 and then place the pipe that needs to be flattened at the top of the main body 1 and between the upper clamping plate 111. Then, initially fix the pipe by screwing the upper clamping plate 111. After that, start the motor 101. When the motor 101 works, it will drive the telescopic shaft 113 to rotate through the belt. When the telescopic shaft 113 rotates, it will drive the machining tool holder 114 to rotate rapidly. Subsequently, after setting parameters on the control panel, start the two electric push rods 122. When the electric push rods 122 work, they will drive the telescopic shaft 113 to extend and make the machining tool holder 114 contact the side wall of the pipe orifice. Then, when the machining tool holder 114 rotates, the effect of flattening the pipe orifice can be achieved.

[0093] When the electric push rod 122 drives the processing tool holder 114 and the parameter error causes the feed speed of the sliding frame 121 driving the processing tool holder 114 to be too fast, the sliding frame 121 will drive the fixed ring 123 to slide synchronously. When the feed speed of the fixed ring 123 is too fast, the rectangular plate on the fixed ring 123 will impact the side wall of the moving rod 211. When the moving rod 211 is impacted, the impact force received by the moving rod 211 will be transmitted to the elastic ball. At this time, when the rotating plate 221 is impacted, the elastic ball will push the rotating plate 221 and the hollow plate 223 to rotate to both sides through the return spring 224. When the hollow plate 223 rotates outwards, it will be stuck in the fixed ring inside the hollow frame 201. At the same time, when the rotating plate 221 rotates, it will be stuck in the toothed plate 233. After that, when the moving rod 211 continues to slide, it will push the hollow plate 223 and the rotating plate 221. At this time, after the hollow plate 223 is blocked by the fixed ring, it will drive the rotating plate 221 to rotate through the C-shaped frame 222. When the rotating plate 221 rotates, it will push the arc plate 232 to slide downwards. At this time, multiple arc plates 232 will wrap and clamp the surface of the pipeline. At the same time, when the rotating plate 221 rotates, it will push the pipeline to slide towards the direction of the processing tool holder 114 through the arc plate 232. At this time, the pipeline will slide slightly. Through the extrusion and wrapping of the surface of the pipeline by multiple arc plates 232 and the driving of the pipeline, it is possible to reduce the collision and the backward sliding and deviation of the pipeline when the processing tool holder 114 contacts the pipeline due to the too fast feed speed of the processing tool holder 114 during flat-mouth processing. By driving the small sliding of the pipeline by multiple arc plates 232, it is possible to relieve the situation of machining surface vibration marks or dimensional deviations during flat-mouth processing due to the sudden change of the feed speed, thereby enhancing the stability of the pipeline during processing and the processing quality during feed flat-mouth processing.

[0094] When the arc plate 232 moves downward and squeezes the surface of the pipeline, the arc plate 232 is squeezed by the reaction force of the pipeline and squeezes the corrugated plate 241, and squeezes the side wall of the elastic plate 242 through the middle of the corrugated plate 241. At the same time, the middle of the corrugated plate 241 will extend to both sides after being squeezed when squeezing the elastic plate 242. At this time, the two ends of the corrugated plate 241 will form a stacked state. Subsequently, after the elastic plate 242 is squeezed by the corrugated plate 241, its end will slide towards the side end of the corrugated plate 241 on the inner wall of the arc plate 232 and stretch the telescopic rod 243. When the end of the elastic plate 242 slides towards the stacked side of the corrugated plate 241, it will generate a downward squeezing force on the stacked side of the elastic plate 242. The stacked parts on both sides of the two corrugated plates 241 are squeezed by the elastic plate 242 and then squeeze the side wall of the pipeline, thereby enhancing the friction between the arc plate 232 and the pipeline. By increasing the friction, it is possible to reduce the situation that the arc plate 232 is difficult to drive the pipeline to slide due to the small friction between the arc plate 232 and the pipeline. At the same time, through the stacking of the two ends of the corrugated plate 241, it is also possible to further enhance the stability of the pipeline during flat-mouth processing and improve the processing efficiency.

[0095] When the arc-shaped plate 232 drives the pipeline to slide, the sliding of the arc-shaped plate 232 will push the middle part of the second C-shaped frame 311 through the push plate 301 to rotate it on the side wall of the T-shaped rod. When the second C-shaped frame 311 rotates, it will drive the two second sliding frames 312 to slide between the two right-angle blocks 321. When the two second sliding frames 312 slide, the friction blocks 313 inside the second sliding frames 312 will be squeezed by the inclined surfaces of the right-angle blocks 321, thereby driving the second sliding frames 312 to slide. At this time, the two second sliding frames 312 will slide relatively. When the two second sliding frames 312 and the friction blocks 313 slide relatively, they will quickly squeeze and rub the rectangular plate, thereby slowing down the feeding speed of the fixed ring 123 driving the machining tool holder 114. When the machining tool holder 114 moves rapidly in the reverse direction of the pipeline due to too fast feeding speed, and when the position of the pipeline surface is fixed after being stably clamped, the situation of chipping occurs when the machining tool holder 114 contacts the pipeline due to too fast feeding speed. Thus, the feeding speed during flat facing is slowed down, and the safety and machining quality during flat facing are enhanced.
