Description

Technical Field

[0001] The invention relates to the technical field of cold-cutting saws for plates, in particular to a cold-cutting flying saw machine. Background Art

[0002] Common flying saws are divided into cold cutting saws and hot cutting saws. Ordinary flying saws are tungsten steel saw blades that rotate at high speed. When they contact the welded pipe, they generate heat and break it, which is actually burnt off. High combustion marks can be seen on the surface. Cold cutting saws rely on high-speed steel saw blades to rotate slowly and cut the welded pipe, so burrs and noise can be reduced. Cold milling is used as the sawing method. The sawing process generates very little heat, avoiding changes in internal stress and material organization at the cut section. At the same time, the saw blade has very little pressure on the steel pipe, which will not cause deformation of the pipe wall or pipe mouth. The cut end of the workpiece processed by the high-speed steel cold cutting saw The surface quality is good. The optimized cutting method is adopted. The section after cutting is of high precision, without burrs inside and outside. The cutting surface is flat and smooth. No subsequent processing such as flat head chamfering is required (reducing the processing intensity of the next process), saving processes and raw materials; the workpiece will not change the material due to the high temperature generated by friction; the operator fatigue is low, and the sawing efficiency is improved; there is no spark, no dust, and no noise during the sawing process; it is environmentally friendly and energy-saving; the service life is long, and the saw blade gear grinder can be used to repeatedly grind the teeth. The life of the saw blade after grinding is the same as that of the new saw blade. Improve production efficiency and reduce costs.

[0003] In the prior art, the publication number "CN106424921B" discloses a CNC double flying saw cold cutting machine, which is characterized in that: the two flying saw devices are connected to each other through an adjustable screw rod and synchronously slide back and forth left and right under the drive of the transverse driving unit; each flying saw device includes a clamping mechanism, which includes two groups of clamping units and a hydraulic cylinder, and a gap is left between the two groups of clamping units for the flying saw to pass through, and each group of clamping units includes a fixed block fixed on the base and a rocker arm pivotally mounted on the base, and the fixed block and the rocker arm are provided with corresponding notches for clamping metal pipes; a conveying pipe is provided between the two flying saw devices. Two metal pipes can be cut and produced at the same time in each working cycle, which greatly improves the production efficiency. The required cutting length can be freely adjusted by adjusting the interval between the two flying saw devices through the screw rod.

[0004] However, the existing technology still has major deficiencies, such as:

[0038] The plate cold cutting surface covering type pressing auxiliary unit is arranged in the cold cutting groove 11 area, and is used to keep the surface of the plate stable when the plate is cold cutting, so as to ensure stable processing during the cold cutting process;

[0041] In this embodiment, by driving the rotating shaft 9 to rotate, the rotation of the rotating shaft 9 will drive the parallel rotating arm 91 to rotate and unfold toward the plate workpiece. After the parallel rotating arm 91 is unfolded obliquely, the parallel rotating arm 91 is located at the top of the plate workpiece. Then, the pneumatic telescopic rod 92 is driven to drive the anti-slip pressure plate 93 to unfold downward.

[0043] The lateral support anti-shake unit for the cold-cutting tool for sheet metal includes an arc-shaped guide part, which includes an arc-shaped slide 51. The arc-shaped slide 51 is installed on the top of the arc-shaped fixed seat 5. Two groups of arc-shaped slides 51 are installed on the top of each group of arc-shaped fixed seats 5. A movable slide column 52 is installed between adjacent arc-shaped slides 51. A fixed spindle 7 is installed at one end of the movable slide column 52. An output spindle 8 is installed on one side of the fixed spindle 7. A high-speed steel circular saw blade 81 is arranged at one end of the output spindle 8. A mounting arm 6 is installed on the surface of the fixed spindle 7. A chip prevention shell 61 is arranged on the part of the mounting arm 6 close to the high-speed steel circular saw blade 81. Adjacent chip prevention shells 61 are snap-fitted and covered on the outer surface of the high-speed steel circular saw blade 81.

[0044] The lateral support anti-shake unit for cold-cutting tools for plates also includes a lateral holding part, which includes a triangular mounting frame 71. The triangular mounting frame 71 is covered and mounted on the outer surface of the fixed main shaft 7. The end of the triangular mounting frame 71 is arranged in three groups. A hydraulic telescopic rod 72 is embedded in the end of the triangular mounting frame 71, and a retaining ball 73 is arranged on the top of the hydraulic telescopic rod 72.

[0045] In this embodiment, the hydraulic telescopic rod 72 can be driven to extend outward, and the hydraulic telescopic rod 72 drives the retaining ball 73 to move partially close to the side of the high-speed steel circular saw blade 81, and then the retaining ball 73 is lightly attached to the surface of the high-speed steel circular saw blade 81, so as to realize the vertical state maintenance function of the high-speed steel circular saw blade 81 during the cold cutting process.

[0046] Embodiment 2:

[0047] Based on the first embodiment, this embodiment takes into account that the workpiece may not be calibrated laterally by manually feeding the workpiece, and the tool is manually driven to cut, and the tool is limited by the unstable factor of the hand, resulting in the tool being unable to maintain a vertical cutting state for a long time. Therefore, this embodiment is provided with a plate cold cutting tool guiding and pushing cutting unit to avoid the above problems;

[0048] A placement bin 4 is disposed on one side of the base 2 close to the cold cutting station 1 , an installation cavity 41 is disposed inside the placement bin 4 , and a plate cold cutting tool guiding and pushing cutting unit is disposed in the installation cavity 41 .

[0049] The plate cold cutting tool guiding and pushing cutting unit includes an L-shaped fixed arm 43, which is installed inside the installation cavity 41. A movable shaft 44 is installed between adjacent L-shaped fixed arms 43. A movable motor 46 is installed on one side of an L-shaped fixed arm 43. The output end of the movable motor 46 is fixed to one end of the movable shaft 44. A movable rotating arm 45 is rotatably sleeved on the surface of the movable shaft 44. A movable groove 42 is provided on the top of the placement bin 4. One end of the movable rotating arm 45 passes through the movable groove 42 and is rotatably sleeved on one end of the movable sliding column 52.

[0050] In this embodiment, the output spindle 8 is driven to rotate slowly, and the output spindle 8 drives the high-speed steel circular saw blade 81 to rotate and cut, and then the movable motor 46 is controlled to output power, and the movable motor 46 drives the movable shaft 44 and the movable rotating arm 45 to rotate. When the movable rotating arm 45 rotates, the fixed spindle 7 can be driven by the movable sliding column 52 to slide in an arc along the inner cavity of the arc slide 51. At this time, the high-speed steel circular saw blade 81 follows the movement and enters the cold cutting groove 11 along the cutting knife walking groove 18 area to perform cold cutting processing on the plate workpiece.

[0051] Working principle: During the use of the device, the operator first puts the plate workpiece to be cut and milled into one side of the cold cutting groove 11, and then the operator drives the movable guide rail 121 to move, and the movable guide rail 121 moves to drive the primary side guide wheel 122 to partially expand outward, and the primary side guide wheel 122 will gradually move to a state of being in contact with the plate workpiece, and push the plate workpiece to move close to the secondary side guide wheel 123 until it is partially in contact with the secondary side guide wheel 123, and then drive the primary side guide wheel 122 and the secondary side guide wheel 123 to rotate. When the primary side guide wheel 122 and the secondary side guide wheel 123 rotate, the plate workpiece can be pushed to continue to move into the cold cutting groove 11. When the plate workpiece reaches the cutter walking groove 18 area, the primary side guide wheel 122 and the secondary side guide wheel 123 are stopped from rotating. When the primary side guide wheel 122 and the secondary side guide wheel 123 stop rotating, the plate workpiece can be locked laterally to the current state to ensure stable cutting of the plate workpiece during the cold cutting process.

[0052] After the plate workpiece is moved into place, in order to ensure the vertical movement of the plate during the cold cutting process, the rotating shaft 9 can be driven to rotate. The rotation of the rotating shaft 9 will drive the parallel rotating arm 91 to rotate and unfold toward the plate workpiece. After the parallel rotating arm 91 is completely unfolded obliquely, the parallel rotating arm 91 is located at the top of the plate workpiece. Then, the pneumatic telescopic rod 92 is driven to drive the anti-slip pressure plate 93 to unfold downward. The anti-slip rubber layer provided at the bottom of the anti-slip pressure plate 93 will be slowly pressed on the surface of the plate workpiece. Multiple groups of anti-slip pressure plates 93 will simultaneously perform upper compression support from the proximal and distal areas close to the cutting area of ​​the plate workpiece to further improve the stability of the plate workpiece during the cold cutting process.

[0053] As the anti-skid pressure plate 93 gradually presses the surface of the sheet workpiece, the anti-skid convex pad 14 originally located at the bottom of the sheet workpiece will be gradually compressed from the original convexity, and the air in the compressed anti-skid convex pad 14 will be quickly discharged outward through the exhaust pores 15. The gas in the internal cavity of the anti-skid convex pad 14 will be completely flattened after being discharged, so that the contact between the anti-skid convex pad 14 and the bottom of the sheet workpiece becomes larger. At the same time, the multi-pore setting on the surface of the anti-skid convex pad 14 can improve the surface roughness of the anti-skid convex pad 14 area, so as to avoid the sliding problem that may occur in the sheet workpiece during the cold cutting process;

[0054] After the surface of the plate workpiece is calibrated in multiple positions and installed in place, the plate workpiece is immediately cold-cut. At this time, the output spindle 8 is driven to rotate slowly, and the output spindle 8 drives the high-speed steel circular saw blade 81 to rotate and cut. Then, the movable motor 46 is controlled to output power, and the movable motor 46 drives the movable shaft 44 and the movable rotating arm 45 to rotate. When the movable rotating arm 45 rotates, the fixed spindle 7 can be driven by the movable slide column 52 to slide along the inner cavity of the arc slide 51 in an arc shape. At this time, the high-speed steel circular saw blade 81 follows the movement and enters the cold cutting groove 11 along the cutter walking groove 18 area to perform cold cutting on the plate workpiece, thereby ensuring the smooth movement of the high-speed steel circular saw blade 81 during the cold cutting process.

[0055] Before the high-speed steel circular saw blade 81 is cold-cut, in order to ensure that the two sides of the high-speed steel circular saw blade 81 rotate concentrically, the hydraulic telescopic rod 72 can be driven to extend outward, and the hydraulic telescopic rod 72 drives the retaining ball 73 to move partially close to the side of the high-speed steel circular saw blade 81, and then the retaining ball 73 is slightly attached to the surface of the high-speed steel circular saw blade 81, so as to realize the vertical state maintenance function of the high-speed steel circular saw blade 81 during the cold cutting process. At the same time, since the triangular mounting frame 71 is provided with multiple sets of end points, the high-speed steel circular saw blade 81 will be supported by multi-point synchronous calibration laterally, which further improves the stability of the high-speed steel circular saw blade during the cutting and milling process and ensures the service life of the high-speed steel circular saw blade 81.
