Description

Technical Field

[0001] The invention belongs to the technical field of flat steel processing, and in particular relates to equipment for producing special-shaped incisions of electrode flat steel. Background Art

[0002] Electrode flat steel is a steel material with a specific shape and size, widely used in various electrical equipment and industrial production, particularly in the welding, smelting, chemical, and electronics industries. Existing electrode flat steel has L-shaped notches cut at the overlap to improve joint strength and reduce contact resistance. These notches increase the contact surface area during the overlap, thereby reducing contact resistance. Furthermore, since more areas need to be welded, the resulting joint strength is increased.

[0003] However, when cutting the L-shaped notch in the existing motor flat steel, in order to avoid changing the structure of the electrode flat steel, flame cutting and laser cutting are generally not used. Instead, a sawing machine is used for cutting. However, the existing sawing machine can only cut in a single direction. Therefore, if an L-shaped notch is to be cut, multiple sawing machines are required to cooperate, and the electrode flat steel also needs to be flipped, resulting in low production efficiency.

[0004] Therefore, a device for producing special-shaped cuts of electrode flat steel is needed. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for producing special-shaped cuts in electrode flat steel. The device uses a tool rotation unit to drive the saw blade to rotate 90 degrees, so that the sawing machine has both vertical and horizontal cutting capabilities. This overcomes the defects of existing electrode flat steel cutting, which requires multiple sawing machines to cooperate when cutting L-shaped notches, and also requires the electrode flat steel to be flipped, resulting in low production efficiency.

[0011] A controller is electrically connected to the transmission device, the clamping device, the cutting device and the tool rotating unit.

[0012] Preferably, the tool rotation unit includes a second linear drive member, a third linear drive member, a hinge, a support plate, a guide block and a guide wheel. The second linear drive member is symmetrically and horizontally installed on the support frame.

The support plate is connected to the moving end of the third linear drive member through a hinge. The guide block is installed on the support plate. A guide groove cooperating with the saw blade is provided on the guide block. A coolant outlet is provided on the guide block. The guide wheels are grouped in two and are located on both sides of the saw blade. Each group of guide wheels is rotatably installed at both ends of the guide block. The two ends of the saw blade are rotatably connected to the reciprocating drive unit.

[0013] Preferably, a locking unit is further included, the locking unit including a fourth linear drive member, a clamping block and a sleeve, the hinge including a fixed portion and a rotating portion, the fixed portion is connected to the third linear drive member, the rotating portion is connected to the support plate, the fourth linear drive member is mounted on the support plate, the clamping block is mounted on the output end of the fourth linear drive member, the sleeve is mounted on the fixed portion, and the clamping block and the sleeve are corresponding non-rotating body shapes.

[0014] Preferably, it also includes a movable adjustment unit, which includes a servo motor, a laser locator and a screw. The sliding base is slidably installed on the support platform, the servo motor is installed on the support platform, and the output end of the servo motor is connected to one end of the screw through a coupling. The sliding base is provided with a threaded hole that cooperates with the screw, and the screw is rotatably installed in the threaded hole. The axial direction of the screw is parallel to the material transmission direction of the conveying device, and the laser locator is installed on the support platform. The laser locator is electrically connected to the servo motor.

[0015] Preferably, the rotation axis of the saw blade coincides with one side of the cutting edge of the saw blade.

[0021] Compared with the existing technology, the present invention has the following beneficial effects:

[0022] 1. The present invention uses a tool rotation unit to drive the saw blade to rotate 90 degrees, allowing the sawing machine to perform both horizontal and vertical cutting. This allows a single sawing machine to complete the L-shaped cut at the end of an electrode flat steel, eliminating the need for multiple machine tools compared to existing production equipment. Therefore, the present invention not only improves production efficiency but also reduces equipment costs.

[0023] 2. This invention monitors the current of the reciprocating drive unit. When the saw blade makes its second cut, after reaching the designated position, the initial gap will cause the saw blade to become unloaded. At this time, the output current of the reciprocating drive unit decreases, the lifting mechanism or displacement adjustment unit stops moving, and the blade retracts. Compared to program-controlled cutting depth, this can prevent overcutting caused by errors.

[0024] 3. When the tool rotation unit rotates the saw blade, the locking unit releases the lock on the hinge. When the tool rotation unit completes the rotation, the locking unit cooperates with the block and the sleeve to prevent the hinge from rotating, thereby further improving the stability of the tool during the cutting process and reducing errors.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Next, refer to Figures 1 to 7 The working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0037] The conveyor 1 is used to drive the electrode flat steel 7 forward, feed the electrode flat steel 7 and move it to the next process. Due to the large mass of the electrode flat steel 7, the conveyor 1 is preferably driven by a roller conveyor belt combined with a chain drive.

[0038] The clamping and fixing device 2 includes a support platform 21, a clamping plate 22, a sliding base 23 and a first linear drive 24. The sliding base 23 is installed on the support platform 21, and the support platform 21 is located below the conveying device 1. The clamping plate 22 is slidably installed on the sliding base 23. The first linear drive 24 is connected to the clamping plate 22 and is used to control the position of the clamping plate 22. When the conveying device 1 stops and starts, the first linear drive 24 starts to drive the clamping plates 22 to move closer to each other until the electrode flat steel 7 is fixed, thereby preventing the electrode flat steel 7 from shifting during the cutting process of the cutting device 3. The clamping plates 22 are generally in two groups, which can better provide support force and prevent the electrode flat steel 7 from shifting. The first linear drive 24 here is a linear motor, a hydraulic cylinder, an electric push rod, etc.

[0039] The cutting device 3 is installed on the support platform 21. The cutting device 3 includes a protective shell 34, a saw blade 31, a support frame 33, a lifting mechanism 32 and a reciprocating drive unit. The cutting device 3 is installed on the support platform 21. The lifting mechanism 32 is installed on the support platform 21, and the support frame 33 is installed on the lifting mechanism 32 by bolts. The reciprocating drive unit is installed on the support frame 33. Both ends of the saw blade 31 are connected to the reciprocating drive unit. The reciprocating drive unit drives the saw blade 31 to move back and forth, and the lifting mechanism 32 drives the saw blade 31 downward, thereby cutting the electrode flat steel 7. The protective shell 34 is installed on the support frame 33 and is used to surround the reciprocating drive unit to avoid personal safety hazards to the operator and to prevent damage to the reciprocating drive unit. The above-mentioned reciprocating drive unit generally adopts a crank-connecting rod mechanism. The above-mentioned lifting mechanism 32 generally adopts a hydraulic cylinder.

[0040] The controller 8 is electrically connected to the transmission device, the clamping device 2, the cutting device 3 and the tool rotating unit 4, and can control the transmission device, the clamping device 2, the cutting device 3 and the tool rotating unit 4 through a program.

[0041] refer to Figure 5The tool rotation unit 4 includes a second linear drive member 41, a third linear drive member 42, a hinge 43, a support plate 44, a guide block 45 and a guide wheel 47. The second linear drive member 41 is symmetrically mounted horizontally on the support frame 33 by bolts, and the third linear drive member 42 is vertically mounted on the output end of the second linear drive member 41 by bolts, and the direction of the third linear drive member 42 is vertically downward. The support plate 44 is connected to the moving end of the third linear drive member 42 by a hinge 43, and the guide block 45 is mounted on the support plate 44 by bolts. A guide groove is provided on the guide block 45 to cooperate with the saw blade 31, which is used to increase the rigidity of the saw blade 31 to prevent the saw blade 31 from bending during the cutting process. At the same time, the iron filings on the saw blade 31 can be cleaned to avoid affecting the cutting of the saw blade 31. The guide block 45 is connected to a coolant inlet pipe and has a coolant outlet. When the cutting device 3 is activated, coolant is ejected from the outlet, cooling the saw blade 31 and helping to clean scrap metal from the blade 31. Two guide wheels 47 are arranged in a set and positioned on either side of the saw blade 31. Each set of guide wheels 47 is rotatably mounted at each end of the guide block 45. The guide wheels 47 engage the sides of the saw blade 31, increasing the rigidity of the saw blade 31 while reducing friction during movement. Both ends of the saw blade 31 are rotatably connected to the reciprocating drive unit, allowing the saw blade 31 to rotate relative to the reciprocating drive unit without affecting the reciprocating motion of the saw blade 31.

[0042] After the electrode flat steel 7 completes horizontal cutting, the fixed clamping unit releases the electrode flat steel 7, and the conveyor 1 drives the electrode flat steel 7 backward to separate from the saw blade 31. The controller 8 activates the retraction of the second linear drive member 41 and the first linear drive member 24. Since the saw blade 31 is rotationally connected to the reciprocating drive unit and the guide wheel 47 is in contact with the saw blade 31, the guide block 45 and the guide wheel 47 rotate under the interaction with the saw blade 31. Due to errors during rotation, the guide block 45 and the guide wheel 47 may move relative to the saw blade 31. However, as long as the two remain in contact, the rotation is not affected. When the second linear drive member 41 and the first linear drive member 24 retract a specified distance, the saw blade 31 and the guide block 45 rotate 90 degrees, assuming a vertical position, with the teeth of the saw blade 31 facing downward. At this time, the conveying device 1 drives the electrode flat steel 7 to move forward to a position where the end of the horizontal cut is located directly below the saw blade 31. The fixed clamping unit clamps and fixes the electrode flat steel 7. The controller 8 starts the reciprocating drive unit and the lifting mechanism 32, driving the saw blade 31 to cut downward the support distance, thereby cutting an L-shaped notch in the electrode flat steel 7. The operator can also use the present invention to cut other special-shaped cuts. The above-mentioned second linear drive member 41 and the third linear drive member 42 are linear motors, hydraulic cylinders, electric push rods, etc. If the operator first cuts the electrode flat steel 7 in the vertical direction, a movement opposite to the above is performed. The principle is the same and will not be elaborated here.

[0043] refer to Figure 5 and Figure 7 The locking unit includes a fourth linear drive member 51, a block 52 and a sleeve 53. The hinge 43 includes a fixed part and a rotating part. The fixed part is welded to the third linear drive member 42, and the rotating part is welded to the support plate 44. When the saw blade 31 rotates, the rotating part is connected to the support plate 44 and will therefore rotate synchronously with it, rotating relative to the fixed part. The fourth linear drive member 51 is mounted on the support plate 44 by bolts, the block 52 is mounted on the output end of the fourth linear drive member 51 by bolts, and the sleeve 53 is mounted on the fixed part by bolts. The block 52 and the sleeve 53 have the same rotation axis. The block 52 and the sleeve 53 are corresponding non-rotating body shapes, so the two cannot rotate relative to each other, forming a limit. When the tool rotation unit 4 rotates the saw blade 31, the fourth linear drive member 51 drives the block 52 to leave the sleeve 53, releasing the lock on the hinge 43. When the tool rotating unit 4 completes its rotation, the fourth linear drive member 51 drives the block 52 to engage with the sleeve 53, so that the hinge 43 cannot rotate, thereby further improving the stability of the tool during the cutting process, reducing errors, and improving production quality.

[0044] The opening of the sleeve 53 is chamfered to facilitate the insertion of the clamping block 52, preventing interference and damage due to errors. Both the sleeve 53 and the clamping block 52 are square. Since the saw blade 31 is rotated 90 degrees, and the four corners of the square are all 90 degrees, the clamping block 52 can still be connected to the sleeve 53 after rotation. A multiple of a quadrilateral can also be used.

[0045] In another embodiment, the locking unit may also be fixed by friction using an electromagnet in combination with a friction pad. This is simpler than the fixing structure using the block 52 and the sleeve 53, but the fixing rigidity is poor. The choice may be made based on actual conditions.

[0046] refer to Figure 3The movement and adjustment unit 6 includes a servo motor 61, a laser positioner, and a lead screw 62. The sliding base 23 is slidably mounted on the support platform 21. The servo motor 61 is mounted on the support platform 21. The output end of the servo motor 61 is connected to one end of the lead screw 62 via a coupling. The sliding base 23 is provided with a threaded hole that mates with the lead screw 62. The lead screw 62 is rotatably mounted within the threaded hole. The axial direction of the lead screw 62 is parallel to the material conveying direction of the conveyor 1. The laser positioner is mounted on the support platform 21 and is electrically connected to the servo motor 61. The laser positioner monitors the position of the electrode flat steel 7, ensuring that after the electrode flat steel 7 retracts and the saw blade 31 rotates, the electrode flat steel 7 can move to a position where the end of the horizontal cut is directly below the saw blade 31. The lead screw 62 drives the sliding base 23, thereby replacing the transmission device to control the advance and retraction of the electrode flat steel 7. This avoids errors caused by dynamic friction between the electrode flat steel 7 and the roller during movement, thereby improving production quality.

[0047] The rotation axis of the saw blade 31 coincides with one side of the blade edge of the saw blade 31, so that before and after the saw blade 31 rotates, the straight line connecting the tips of the saw teeth remains in the same horizontal and vertical planes, thereby eliminating the need for compensation adjustment and reducing processing difficulty.

[0048] The distance between each set of guide wheels 47 is smaller than the width of the guide groove. The guide wheels 47 fit the side walls of the saw blade 31. Generally, the guide groove does not contact the saw blade 31. The guide wheels 47 contact the saw blade 31 and generate dynamic friction with the saw blade 31, thereby reducing the resistance and friction on the saw blade 31.

[0049] A current monitoring device is installed on the support frame 33, which is used to monitor the output current of the reciprocating drive unit and transmit the measured current data to the controller 8. When the saw blade 31 is unloaded, the drive motor only needs to overcome its own friction and the rotational resistance of the saw blade 31, and the current / power consumed is low and stable. When the saw blade 31 starts to cut the material, the load increases sharply, and the motor needs to output a greater torque, resulting in a significant increase in current / power. When the saw blade 31 performs the second cutting, after the saw blade 31 cuts to the specified position, the first gap will cause the saw blade 31 to be unloaded. At this time, the output current of the reciprocating drive unit will decrease, the lifting mechanism 32 or the displacement adjustment unit will stop moving, and the blade will be retracted. Compared with controlling the cutting depth through a program, over-cutting of the saw blade 31 due to errors can be avoided.

[0050] The present invention is also equipped with a tool wear detection system, which monitors the wear status of the saw blade 31 in real time through a sensor and issues a replacement prompt when a preset wear threshold is reached, thereby ensuring production effect and production efficiency.

[0051] In summary, the use process of the present invention is as follows: the conveying device 1 moves the electrode flat steel 7 to the designated position, the clamping and fixing unit fixes the electrode flat steel 7, the cutting unit performs horizontal cutting on the electrode flat steel 7, and the movable adjustment unit 6 drives the electrode flat steel 7 to move and advance. After cutting is completed, the movable adjustment unit 6 drives the electrode flat steel 7 to move and retract, the tool rotation unit 4 drives the saw blade 31 to rotate 90 degrees, and the movable adjustment unit 6 moves to a position where the end of the horizontal cut is directly below the saw blade 31. The cutting unit performs vertical cutting on the electrode flat steel 7 until it reaches the intersection of the horizontal cuts, thereby completing the processing of the electrode flat steel 7. The fixed clamping unit contacts the electrode flat steel 7, and the conveying device 1 drives the electrode flat steel 7 away from the workstation.
