[0023] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] refer to Figure 1 The present invention provides a cold saw chamfering production line, which includes a feeding mechanism 1, a shearing mechanism 2 and a rounding mechanism 3 arranged sequentially along the production line. The shearing mechanism 2 is used to cut the pipe 4 fed by the feeding mechanism 1 into multiple segments, and the rounding mechanism 3 is used to round the outer corners of the cut pipe 4.

[0025] refer to Figure 2 , Figure 3 and Figure 4 The feeding mechanism 1 includes a feeding frame 11, guide side plates 12, a lifting assembly 13, a feeding adjustment assembly 14, and a feeding roller group 15. Multiple guide side plates 12 are evenly distributed along the length of the feeding frame 11. Each guide side plate 12 includes a first guide plate 121 fixed to the feeding frame 11 and a second guide plate 122 vertically disposed at the discharge end of the first guide plate 121. The upper part of the second guide plate 122 extends upwards above the upper surface of the first guide plate 121. Both the upper surfaces of the first and second guide plates 122 are inclined in the same direction. During feeding, multiple pipes 4 are placed on the first guide plate 121 and roll down along its inclined direction, being blocked by the second guide plate 122. At this time, the multiple pipes 4 are stored on the guide side plates 12.

[0026] refer to Figure 2 , Figure 3 and Figure 4 Each guide plate 12 has a lifting assembly 13 on one side. The lifting assembly 13 is used to lift the pipes 4 on the first guide plate 121 one by one onto the second guide plate 122, thereby realizing the one-to-one delivery of multiple pipes 4 stored on the guide plate 12. The lifting assembly 13 includes a strip tooth 131 vertically and slidably connected to the side of the second guide plate 122, a lifting plate 132 connected to the strip tooth 131, and a driving member 133 that simultaneously drives each strip tooth 131 to move up and down reciprocally. One side of the lifting plate 132 extends to one side of the first guide plate 121 in the width direction. The upper end surface of the lifting plate 132 is also inclined, and the inclination angle and direction are consistent with the upper end surface of the first guide plate 121 and / or the second guide plate 122. The driving component 133 includes a drive shaft 1331 that passes through and is rotatably connected to multiple second guide plates 122, a gear 1332 mounted on the drive shaft 1331 and meshing with each rack tooth 131, and a drive motor that drives the drive shaft 1331 to rotate. In this lifting assembly 13 structure, the gear 1332 and the rack tooth 131 have line contact, resulting in a large meshing area, allowing it to withstand high loads, stable force output, high positioning accuracy, good self-locking performance, strong structural rigidity, strong resistance to off-center loads, flexible stroke length design, relatively simple maintenance, and high reliability. The lifting assemblies are independently configured, facilitating disassembly and maintenance if any one of the lifting assemblies is damaged.

[0027] refer to Figure 2 , Figure 3 and Figure 4 The feeding adjustment component 14 works in conjunction with the lifting component 13 to convey pipes 4 of different diameters. The feeding adjustment component 14 is located between the lifting component 13 and the guide side plate 12. The feeding adjustment component 14 includes a guide rail 141 horizontally arranged on the side of the first guide plate 121, a slider 142 slidably connected to the guide rail 141, an adjustment plate 143 vertically arranged and fixed on the slider 142, and a second driving member 144. One end of the guide rail 141 extends to the second guide plate 122. The second driving member 144 is used to drive the slider 142 to move back and forth along the length of the guide rail 141, thereby adjusting the position of the adjustment plate 143. The horizontal width of the adjustment plate 143 is smaller than the horizontal width of the lifting plate 132. The adjusting plate 143 reciprocates along the width of the lifting plate 132. When the adjusting plate 143 is completely located on one side of the second guide plate 122, the diameter of the lifted pipe 4 is at its maximum. The second driving component 144 includes a turbine screw jack 1441 set on each guide side plate 12 and a working drive rod 1442 that drives each turbine screw jack 1441. One end of the drive rod 1442 is equipped with a manually operated handwheel 1443. The lifting screw in the turbine screw jack 1441 is connected to the slider 142. When conveying different pipes, it can be finely adjusted manually to improve accuracy.

[0028] refer to Figure 2 , Figure 3 and Figure 4 The feeding roller assembly 15 is located below the discharge end of the second guide plate 122 on one side. The feeding roller assembly 15 guides the conveyed pipe 4, facilitating its feeding into the shearing mechanism 2. The feeding roller assembly 15 includes a supporting steel pipe 151 connecting multiple second guide plates 122, a support seat 152 along the length of the steel pipe 151 and located between two adjacent second guide plates 122, a conveying roller 153 disposed above each support seat 152, and a third driving member 154 that simultaneously drives the conveying roller 153 to move longitudinally. The conveying roller 153 includes a conveying roller seat 1531 and a conveying roller 1532 rotatably connected to the conveying roller seat 1531. The third driving member 154 includes a rotating shaft 1542 whose longitudinal telescopic end is connected to the bottom end of the conveying roller seat 1531 and is connected to the elevator 1541, and which simultaneously drives the elevator 1541. A rotating handwheel 1543 is disposed on one side of the rotating shaft 1542 to drive its rotation. When conveying pipes 4 of different diameters, the handwheel 1543 drives the elevator 1541 to drive the conveying rollers 153 for longitudinal fine-tuning, thereby ensuring that the conveying rollers 153 can support and convey pipes 4 of different diameters. The rotating shaft between two adjacent drive elevators is detachable for easy maintenance.

[0029] refer to Figure 5 , Figure 6 and Figure 7 The shearing mechanism 2 includes a body 21, a support frame 22 inclinedly mounted on the body 21, a cutter 23 slidably connected to the support frame 22, and a first drive cylinder 24 that drives the cutter 23 to reciprocate along the inclined direction of the support frame 22. A protective cover (not shown in the figure) is provided on the body 21, and a shielding aluminum curtain 5 is provided on the bottom side of the support frame 22. When the cutter 23 cuts, the shielding aluminum curtain 5 serves to shield the cutting process and prevent the waste chips generated during cutting from splashing.

[0030] refer to Figure 5 , Figure 6 and Figure 7A first pipe clamping member 6 is slidably provided on the machine body 21 and at the feed end of the cutting machine 23, and a second pipe clamping member 7 is provided on the machine body 21 and at the discharge end of the cutting machine 23. The first pipe clamping member 6 is used to drive the pipe 4 on the conveying roller group 153 to feed to the second pipe clamping member 7. The first pipe clamping member 6 uses a dual-axis or tri-axis cylinder jaw. The pipe 4 is relatively long. When the pipe 4 falls into the conveying roller 153, one end of the pipe 4 is located on the machine body 21. At this time, the first pipe clamping member 6, which is slidably connected to the machine body 21, slides to the end of the machine body 21 and clamps the end of the pipe 4. Then, it pulls the pipe 4 towards the second pipe clamping member 7 until the second pipe clamping member 7 can clamp the pipe 4. Therefore, the first pipe clamping member 6 plays the role of pulling the material, that is, pulling the pipe 4 from the conveying roller 153 into the shearing mechanism 2, and also plays the role of fixing the pipe. When cutting the pipe, the first pipe clamping member 6 and the second pipe clamping member 7 cooperate to fix the pipe 4, which facilitates the cutting machine 23 to cut the pipe 4. Moreover, by moving the pipe 4 through the first pipe clamping member 6, the conveying accuracy and clamping accuracy of the pipe can be improved.

[0031] refer to Figure 5 , Figure 6 and Figure 7 The second pipe clamping component 7 includes a clamping seat 71, a fixed clamping block 72 disposed on the upper end of the clamping seat 71, a movable clamping block 73 slidably connected to the clamping seat 71, and a second driving cylinder 74 disposed on the clamping seat 71 for driving the movable clamping block 73 to move. The fixed clamping block 72 and the movable clamping block 73 are both provided with gaps 8 for avoiding the cutting wheel in the cutting machine 23. The second pipe clamping component 7 also includes a pressing block 75 disposed on the feeding side of the clamping seat 71 and a pressing cylinder 76 for driving the pressing block 75 to move. When the pipe 4 is clamped by the second pipe clamping component 7, the pressing cylinder 76 drives the pressing block 75 to move, so that the pressing block 75 presses against the outer circumference of the pipe 4, preventing the pipe 4 from jumping up and down during cutting. The movable clamping block 75 and the fixed clamping block 72 cooperate to achieve front and rear positioning of the pipe 4, improve the firmness of the pipe 4, and prevent movement during cutting.

[0032] refer to Figure 5 , Figure 6 and Figure 7 A material head discharge assembly 9 is provided at the discharge end of the machine body 21. When the long pipe 4 is cut into sections, the end of the pipe 4 is cut off first, and the removed material head is discharged through the material head discharge assembly 9.

[0033] refer to Figures 8-11The rounding mechanism 3 includes a material pulling assembly 31 and a rounding assembly 32. The material pulling assembly 31 includes a material pulling box 311, a plurality of liftable suspension roller groups 312 arranged along the length of the material pulling box 311, and a material pulling component 313 that pulls the cut pipe 4 onto the plurality of suspension roller groups 312. The material pulling component 313 is slidably connected to the material pulling box 311. A material ejection plate 314 for pushing the pipe 4 off the suspension roller group 312 is provided between two adjacent suspension roller groups 312.

[0034] refer to Figures 8-11 The rounded corner assembly 32 includes a rounded corner box 321 and a third pipe clamping member 322 disposed on the discharge side of the feeding box 311. There are two third pipe clamping members 322 disposed opposite to each other on both sides of the upper end face of the rounded corner box 321 along the length direction. The ends of the upper end face of the rounded corner box 321 are respectively provided with rounded corner power members 323 for rounding the ends of the clamped pipe 4. The rounded corner box 321 is also provided with a material support member 324 for placing the pipe 4 in the feeding assembly 31 into the two third pipe clamping members 322.

[0035] refer to Figures 8-11 The material support 324 includes two receiving plates 3241 disposed on the chamfered box 321 and located between two third pipe clamping members 322, and a receiving baffle 3242 disposed on each receiving plate 3241. The receiving end of the receiving plate 3241 is inclined upward. A feeding member 10 for feeding the pipe 4 on the receiving plate 3241 into the third pipe clamping member 322 is disposed between the two receiving plates 3241.

[0036] refer to Figures 8-11 The loading component 10 includes a base 101 mounted on a chamfering box 321, a support plate 102 reciprocating on the base 101, support plates 103 at both ends of the support plate 102 along its length, and a lifting component (not shown in the figure) that drives the base 101 to move longitudinally. The support plates 103 are perpendicular to the support plate 102, and both sides of the upper surface of the support plate 103 along its length have notches 104 for placing the pipes 4. This loading component 10 is a dual-station loading component, with one notch 104 for loading and the other for unloading. The spacing between the loading notch 104 and the unloading notch 104 ensures that when a new pipe 4 is retrieved, the chamfered pipe 4 can be removed from the third pipe clamping component 322.

[0037] refer to Figures 8-11 The chamfering power unit 323 includes a drive motor 3231 mounted on the chamfering box 321, a tool holder 3232 connected to the drive end of the drive motor 3231, and a tool head 3233 mounted opposite to the tool holder 3232.

[0038] refer to Figures 8-11When the rounding component 3 is working, the material pulling component 313 and the first pipe clamping component 6 cooperate to transport the cut pipe 4 to the suspension roller group 312. After that, the suspension roller group 312 moves down and exits, and the pipe 4 is placed on the ejector plate 314. The ejector plate 314 drops the material onto the receiving plate 3241. The support plate 102 drives the support plate 103 to move along the length direction of the base 101. At the same time, the lifting component drives the base 101 to move upward. Under the combined action, the material is picked up, that is, the pipe 4 is clamped in the notch 104 of the loading position. Then, the loading component 10 drives the pipe 4 to move and place the two ends of the pipe 4 into the two third pipe clamping components 322 for clamping. Then, the rounding power component 323 realizes the chamfering work on the outer circles of the two ends of the pipe 4. After the rounding is completed, the loading component 10 takes the rounded pipe 4 out of the third pipe clamping component 322 and discharges it. At the same time, a new pipe to be processed is picked up.

[0039] In summary, this cold saw chamfering production line can cut long pipes into short pipes of the required length and can chamfer the outer corners of the cut short pipes. The entire production line has a compact structure and a high degree of automation, which can improve the processing efficiency of chamfering the outer corners.
