Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting machines, in particular to a saw blade metal cutting machine. BACKGROUND

[0002] The saw blade metal cutting machine is an important cutting equipment, which mainly relies on the friction force and cutting force generated between the high-speed rotating saw blade and the metal material to realize cutting. The motor drives the saw blade to rotate at high speed. When the saw blade contacts the metal material, the saw teeth continuously cut the metal to separate the metal material into the required shape and size.

[0003] Experienced operators generally intermittently move up and then press down when using the cutting machine, especially when cutting thick-walled metal (similar to cutting thick wood, experienced masters will hold the electric saw to slow down and press down, and will appropriately lift the electric saw to improve cutting efficiency). The main reasons are two core elements, namely:

[0004] 1. Intermittent pressing: the debris generated by cutting will accumulate in the cutting gap, causing the cutting resistance to gradually increase, and the cutting efficiency will be significantly reduced, and even the cutting may not move, which hinders the further cutting of the cutting blade, and even damages the saw blade of the cutting machine and affects its service life.

[0005] 2. Speed control: when cutting thick metal, the existing high-speed cutting machine can generate sufficient cutting force to cut off the metal piece under the high-speed holding. Even if the intermittent pressing method is used, the reasonable speed control will still generate high friction resistance to the saw blade. Although the cutting process will be accelerated, the saw blade will be greatly worn, and the structural strength of the saw blade will be damaged.

[0006] Therefore, how to reasonably control the pressing speed through high coordination with the operator and find the protection balance point during cutting of heavy metal pieces is a problem that needs to be solved and faced by the current saw blade metal cutting machine.

[0007] Therefore, the present application provides a high-protection metal cutting machine that can reduce the thermal wear of the saw blade. SUMMARY

DETAILED DESCRIPTION

[0060] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0061] Please refer to Figures 1 to 14 The present application provides a technical solution: a saw blade metal cutting machine, comprising a base 1, a cutting head 3 hingedly connected to the top end of the base 1, and a circular shell 6 fixed to the back of the cutting head 3, further comprising:

[0062] A pushing block 5 fixed to the surface of the cutting head 3 rotates concentrically with it to generate a pushing force;

[0063] A hydraulic tank 9 for storing hydraulic oil is fixed to the top end of the base 1, and a pressing rod 10 that moves downward under the pushing force generated by the rotation of the pushing block 5 is movably inserted into the top end of the hydraulic tank 9;

[0064] A hollow tank 8 is connected and arranged on one side of the hydraulic tank 9, and a pushing rod 13 that moves upward under the hydraulic pressure based on the change of flow rate is movably inserted into the top end of the hollow tank 8;

[0065] A liquid storage tank 4 for temporarily storing hydraulic oil is connected and arranged on the other side of the hollow tank 8;

[0066] The adjusting rod 15 is movably arranged on the surface of the circular shell 6 and rotates with the pushing force of the push rod 13;

[0067] The locking assembly is movably arranged on the inner wall of the circular shell 6 and comprises the limiting block 17 which rotates with the adjusting rod 15 and adaptively locks the cutting head 3.

[0068] The inner wall of the limiting block 17 is hingedly connected with the connecting rod 18 which moves with the rotation of the adjusting rod 15.

[0069] In specific implementation, the locking assembly further comprises the shaft rod 11 which is concentrically arranged on one side of the circular shell 6; the two ends of the shaft rod 11 respectively extend to the outer surface and the inner wall of the circular shell 6, and the surface of the shaft rod 11 is provided with a plurality of limiting rings.

[0070] In addition, it should be noted that the limiting rings can limit the rotation of the adjusting rod 15 and will not rotate with the rotation of the circular shell 6; when the adjusting rod 15 is subjected to a pushing force, it can rotate; the rotation of the adjusting rod 15 drives the rotation of the shaft rod 11, and the rotation of the shaft rod 11 drives the rotation of the special-shaped block 19 and the connecting rod 18, so that the rotation of the adjusting rod 15 synchronously drives the rotation of the special-shaped block 19 and the connecting rod 18.

[0071] The end of the shaft rod 11 extending to the outer surface of the circular shell 6 is fixedly sleeved with the adjusting rod 15, and the adjusting rod 15 is composed of a long rod and a circular block.

[0072] The weight of the circular block is greater than that of the long rod, and the adjusting rod 15 is arranged in an inclined manner.

[0073] In addition, it should be noted that the weight of the circular block is greater than that of the long rod, so that the adjusting rod 15 can be kept in an inclined arrangement, and when it is rotated by a pushing force, it can always drive the limiting block 17 to lock the limiting column 16, limit the rotation of the turning arm of the cutting head 3, and protect the saw blade.

[0074] The end of the shaft rod 11 extending to the inner wall of the circular shell 6 is fixedly sleeved with the special-shaped block 19.

[0075] In specific implementation, one end of the connecting rod 18 is symmetrically hingedly connected to the surface of the special-shaped block 19, and the connecting rod 18 is arranged in an inclined manner; the other end of the connecting rod 18 is hingedly connected to the limiting block 17, and the limiting block 17 is symmetrically hingedly arranged on one side of the inner wall of the circular shell 6.

[0076] In addition, it should be noted that the rotation of the shaft rod 11 drives the simultaneous rotation of the special-shaped block 19 and the connecting rod 18; the inclined connecting rod 18 rotates clockwise outward to push the two sets of limiting blocks 17 to move; at this time, the inclination angles of the two sets of connecting rods 18 become smaller, and the symmetric connecting rods 18 are simultaneously expanded to push the limiting blocks 17 to move upward.

[0077] In specific implementation, the inner wall of the circular shell 6 is rotatably inserted with the limiting column 16, and the limiting column 16 is composed of two parts of a disc and a circular rod; the inner wall of the disc is matched with the two side arcs of the outer surface of the limiting block 17, and the inner wall of the disc and the outer surface of the limiting block 17 are respectively fixedly laid with rubber pads, and a gap is left between the limiting column 16 and the limiting block 17; one end of the circular rod is movably penetrated through the other side of the circular shell 6 and fixed with the cutting head 3, and the circular rod is not in contact with the shaft 11.

[0078] In addition, it needs to be noted that the circular rod of the limiting column 16 is fixedly connected with the shaft end of the motor, and the limiting column 16 rotates in the circular shell 6 with the rotation of the motor driving the saw blade, and the limiting column 16 and the limiting block 17 are not in contact with each other and leave a gap, so that the rotation of the limiting column 16 will not drive the limiting block 17 to rotate.

[0079] In specific implementation, the top end of the base 1 is installed with the cutting head 3, and the top end of the base 1 is hingedly connected with the cutting head 3; the cutting head 3 includes a front clamping plate, a rear clamping plate, an adjusting seat and an adjusting screw; the cutting head 3 includes a saw blade, a rotating shaft, a motor, a turnover arm and a protective cover; one side of the rotating shaft is fixed with the circular rod of the limiting column 16.

[0080] In addition, it needs to be noted that the workpiece is placed between the front clamping plate and the rear clamping plate during use, the adjusting screw in the middle of the adjusting seat is rotated, the clamping is adjusted according to the shape and size of the workpiece, the motor is started by the external power supply and the control switch to drive the saw blade to rotate, the turnover arm is held to drive the motor, the saw blade and the protective cover to move, the saw blade is contacted and cut with the workpiece by pressing down and rotating the turnover arm, and the rotating shaft of the clamping assembly 2 is simultaneously rotated after the turnover arm is pressed down, so as to drive the limiting column 16 to rotate.

[0081] In specific implementation, the liquid storage tank 4, the hollow tank 8 and the hydraulic tank 9 are all in "L" shape, and the hollow tank 8 and the hydraulic tank 9 are located on the horizontal side of the clamping assembly 2; the hollow tank 8 and the hydraulic tank 9 are not in the same horizontal plane as the cutting head 3.

[0082] In addition, it needs to be noted that the workpiece will not be contacted with the liquid storage tank 4, the hollow tank 8 and the hydraulic tank 9 when the cutting head 3 is pressed down and rotated, and the workpiece can be normally placed, and the cutting head 3 can also be smoothly rotated.

[0083] In specific implementation, the reset rod 7 is movably inserted in the liquid storage tank 4, and the surface of the reset rod 7 is wound with a reset spring 12.

[0084] The two ends of the reset spring 12 are respectively fixed with the top end of the inner wall of the liquid storage tank 4 and one end of the bottom end of the reset rod 7.

[0085] In the embodiment, the push block 5 is composed of a fixed rod and a convex block; the fixed rod is fixed on the surface of the cutting head 3, and the surface of the convex block is an arc-shaped surface with chamfering treatment; the surface of the convex block is in contact with the top end of the pressing rod 10.

[0086] In addition, it should be noted that as the cutting head 3 drives the push block 5 to rotate continuously, the push block 5 continuously applies pressure to the pressing rod 10, and the pressing rod 10 is continuously pressed in the hydraulic tank 9, so that the hydraulic oil in the hydraulic tank 9 is squeezed out.

[0087] In the embodiment, the hollow tank 8 is respectively connected with two connecting pipes 14 with different diameters, one end of the connecting pipe 14 with a larger diameter is connected with the hydraulic tank 9, and the other end of the connecting pipe 14 with a smaller diameter is connected with the liquid storage tank 4.

[0088] In addition, it should be noted that when the cutting is blocked and the pressure is increased, the hydraulic oil in the hydraulic tank 9 flows into the hollow tank 8 through the connecting pipe 14, at this time, due to the fact that the diameter of the inlet connecting pipe 14 of the hollow tank 8 is larger than that of the outlet connecting pipe 14, the hydraulic oil in the hollow tank 8 cannot flow to the liquid storage tank 4 through the connecting pipe 14 with a small diameter, thereby generating upward hydraulic pressure to push the push rod 13.

[0089] In the embodiment, the push rod 13 is composed of a top weight block and a bottom moving rod; the top end of the weight block is fixedly laid with a rubber pad; the top end of the weight block is in contact with the circular block end of the adjusting rod 15.

[0090] In addition, it should be noted that the rubber material has good friction and certain elasticity, which can protect the parts and increase the friction when the limiting block 17 moves outward to the limiting column 16.

[0091] Working principle: when the saw blade metal cutting machine is used, first, the metal material is placed on the workbench, and according to the shape and size of the material, it is firmly fixed through the clamping assembly 2, and then the motor is started through the external power supply and the control switch to drive the saw blade to rotate, and then the cutting head 3 is held and a proper and uniform pressure is applied downward, so that the cutting blade gradually cuts into the metal;

[0092] With the rotation of the turnover arm, the rotating shaft of the cutting head 3 and the limiting column 16 are also rotated in the base 1. After the cutting head 3 is rotated on the base 1, the push block 5 and the circular shell 6 are simultaneously rotated, the push block 5 is gradually moved above the hydraulic tank 9 to uniformly push the pressure rod 10, the pressure rod 10 moves downward in the hydraulic tank 9 to extrude the hydraulic oil, the hydraulic oil flows into the hollow tank 8 through the large-diameter connecting pipe 14, the counterweight at the top of the push rod 13 has a certain weight, and after the hydraulic oil is uniformly pushed, it will not move upward, and it flows into the storage tank 4 through another group of thin connecting pipes 14. After the hydraulic oil enters the storage tank 4, it pushes the reset rod 7 upward to move, so that the reset spring 12 is forced to retract;

[0093] When cutting for a certain time, debris accumulates in the cutting area, and the cutting resistance needs to be moved upward and repressed. If it is always pressed, the pressure needs to be increased, and then the turnover arm is held to drive the push block 5 to increase the intensity of the downward pressure, so that the pressure rod 10 in the hydraulic tank 9 is pressurized and pushed downward, and a large amount of hydraulic oil in the hydraulic tank 9 flows into the hollow tank 8 through the connecting pipe 14. At this time, because the diameter of the connecting pipe 14 at the inlet of the hollow tank 8 is larger than that at the outlet, the hydraulic oil in the hollow tank 8 cannot all flow into the storage tank 4 through the small-diameter connecting pipe 14, thereby generating upward hydraulic pressure to push the push rod 13;

[0094] After the push rod 13 moves upward under the hydraulic pressure, it pushes the adjusting rod 15, the adjusting rod 15 drives the shaft rod 11 to rotate counterclockwise in the circular shell 6, the shaft rod 11 drives the special-shaped block 19 and the connecting rod 18 to rotate simultaneously, the inclined connecting rod 18 rotates clockwise outward to push the two groups of limiting blocks 17 to move, the limiting blocks 17 rotate and move to the two groups of limiting columns 16 to lock the position of the limiting columns 16, so that the turnover arm of the cutting head 3 cannot rotate in the base 1, and the user will subconsciously hold the cutting head 3 to move upward;

[0095] When cutting is paused, the counterweight at the top of the push rod 13 pushes the hydraulic oil in the hollow tank 8 downward by gravity, and at the same time, the reset spring 12 is forced to return to drive the reset rod 7 to move downward, pushing the hydraulic oil in the storage tank 4 to flow out, at this time, the hydraulic oil returns to the hydraulic tank 9 to reset the pressure rod 10, and the push rod 13 in the hollow tank 8 is reset, so that the limiting block 17 is away from the limiting column 16 after the adjusting rod 15 is reset by gravity, and the turnover arm can be pressed again for cutting, and when the cutting is uniformly pressed, the hydraulic oil in the hydraulic tank 9 flows into the storage tank 4, and the push rod 13 will not be pushed upward, and after use, the hydraulic oil in the storage tank 4 returns to the hydraulic tank 9 under the force of the reset spring 12;

[0096] After use, wait for the saw blade to stop rotating completely, clean the metal debris and oil stains on the saw blade, and clean the metal debris and sundries on the workbench to keep the workbench clean for secondary use.

[0097] Although the present application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be replaced by equivalent features, by those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
