Description

Technical Field

[0001] This utility model relates to the field of metal strip processing technology, specifically to a novel adjustable cross-cutting machine for amorphous composite strips. Background Technology

[0002] Amorphous composite ribbons (such as iron-based amorphous alloys and nanocrystalline ribbons) possess excellent soft magnetic properties and are widely used in the manufacture of high-frequency electronic components such as transformers and inductors. However, amorphous ribbons are brittle and have poor ductility, making them prone to edge chipping, burrs, delamination, and even breakage during traditional shearing processes, which seriously affect product quality and yield.

[0003] Currently, most cross-cutting machines on the market use rigid pressure plates to fix the strip before cutting, which has the following drawbacks:

[0004] Risk of indentation: Rigid clamping plates are prone to leaving indentations on the surface when fixing strips, and may even lead to the propagation of micro-cracks;

[0005] Cutting offset: During the shearing process, the strip may slide laterally due to local stress concentration, resulting in skewed cuts or dimensional deviations.

[0006] Low efficiency: Traditional equipment requires frequent adjustment of clamping force to adapt to strips of different thicknesses, which affects the efficiency of continuous operation;

[0007] Therefore, there is an urgent need for a high-efficiency cross-cutting equipment that can both stably fix amorphous ribbon and avoid mechanical damage. Utility Model Content

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a novel adjustable cross-cutting machine for amorphous composite strips, which can effectively solve the problems mentioned in the background technology.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] This utility model provides a novel adjustable cross-cutting machine for amorphous composite strip, including two L-shaped bases arranged side by side, and a cutting assembly that can be lifted and slid between the two L-shaped bases.

[0011] The cutter assembly includes a cutting seat that slides back and forth between two L-shaped bases, and a cutting blade is rotatably mounted between two opposite inner sidewalls of the cutting seat, the bottom height of the cutting blade being lower than the bottom height of the cutting seat;

[0012] The extrusion fixing assembly includes extrusion seats that are elastically and vertically arranged on both sides of the cutting blade. The bottom of each of the two extrusion seats is provided with a drive belt that can rotate around it. The bottom height of the drive belt is lower than the bottom height of the extrusion seat.

[0013] Furthermore, screws are threaded through the bottom of both L-shaped bases, and two parallel guide rods are vertically fixed between the two L-shaped bases.

[0014] Furthermore, a moving component is jointly installed on both L-shaped bases. The moving component includes a servo motor installed on the outer wall of one of the L-shaped bases, and a lead screw rotatably installed between the two L-shaped bases. One end of the lead screw passes through the corresponding L-shaped base and is connected to the output end of the servo motor.

[0015] Furthermore, a nut seat is threaded onto the lead screw, and a lifting cylinder is vertically fixedly installed at the bottom of the nut seat. Guide blocks are vertically fixedly installed on the two opposite outer walls of the lifting cylinder, and the two guide blocks are slidably mounted on the corresponding guide rods.

[0016] Furthermore, the cutter assembly also includes a drive motor that is vertically fixedly mounted on the outer wall of the cutting seat and whose output end is fixedly connected to the center of one side of the cutting blade.

[0017] Furthermore, the extrusion fixing assembly also includes L-shaped fixing seats fixedly installed on both sides of the cutting seat, and a base is fixedly installed on the bottom of each of the two L-shaped fixing seats.

[0018] Furthermore, two springs are installed between each of the two bases and the corresponding extrusion seat. Each of the two springs contains an insert and a rod that are inserted into each other. The two inserts are vertically fixedly installed on the top of the corresponding extrusion seat, and the two rods are vertically fixedly installed on the bottom of the base.

[0019] Furthermore, two rotating rollers and several support rollers are rotatably mounted on the two opposing inner sidewalls of the two extrusion seats, and the two transmission belts are respectively wrapped around the outer roller walls of the corresponding two rotating rollers, and the bottoms of the several support rollers are in rolling contact with the inner ring wall of the corresponding transmission belt.

[0020] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0021] 1. Dynamic flexible fixation:

[0022] The drive belt runs continuously during cutting, driving the amorphous strip to feed smoothly and avoiding surface scratches caused by traditional static pressure plates. The buffer mechanism composed of springs and insert rods can adapt to strips of different thicknesses to ensure uniform distribution of clamping force.

[0023] 2. High-precision cutting:

[0024] The cutting blade moves synchronously with the drive belt, eliminating lateral displacement of the strip during the shearing process and ensuring the perpendicularity of the cut (deviation ≤0.1mm). The belt drive design allows the strip to be continuously fed during the cutting process without frequent start-stop, increasing production efficiency by more than 30%. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] The present invention will be further described below with reference to the embodiments. Example

[0037] Reference Figure 1-4 The first embodiment of this utility model discloses a novel adjustable cross-cutting machine for amorphous composite strip, including two L-shaped bases 1 arranged side by side. An intelligent control system is embedded in the L-shaped base 1. The intelligent control system includes a laser thickness gauge, a PLC parameter calculation module, and a touch screen human-machine interface.

[0038] Taking an amorphous ribbon with a width of 200mm and a thickness of 0.025mm as an example:

[0039] Enter the material parameters on the touchscreen: t=0.025mm, material=Fe-based;

[0040] The system automatically sets:

[0041] Shear gap: 0.002 mm;

[0042] Tool tilt angle: 22°;

[0043] Clamping force: 8N;

[0044] The strip is conveyed to the cutting position via the platform, and the cutting tool descends at a speed of 0.5m / s. After the shearing is completed, it returns to its original position pneumatically.

[0045] Finished products are automatically sorted by a burr detector.

[0046] It also includes a cutter assembly that can slide up and down between the two L-shaped bases 1;

[0047] The cutting assembly includes a cutting seat 31 that slides back and forth between two L-shaped bases 1. A cutting blade 32 is rotatably mounted between two opposing inner sidewalls of the cutting seat 31. The cutting blade 32 is made of carbide, with a cutting edge angle of 25°±2. The bottom height of the cutting blade 32 is lower than the bottom height of the cutting seat 31.

[0048] The extrusion fixing assembly includes extrusion seats 43 that are elastically and vertically arranged on both sides of the cutting blade 32. The bottom of each extrusion seat 43 is provided with a drive belt 46 that can rotate around it. The drive belt 46 is a polyurethane coated drive belt with a thickness of 1mm and a surface roughness Ra≤0.4μm. The bottom height of the drive belt 46 is lower than the bottom height of the extrusion seat 43 to ensure that the drive belt 46 rolls in contact with the upper surface of the amorphous composite strip. Example

[0049] Reference Figure 1-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: screws 11 are threaded through the bottom of both L-shaped bases 1; two parallel guide rods 12 are vertically fixed between the two L-shaped bases 1; a moving component is installed on both L-shaped bases 1; the moving component includes a servo motor 22 installed on the outer wall of one of the L-shaped bases 1; and a lead screw 21 rotatably installed between the two L-shaped bases 1. One end of the lead screw 21 passes through the corresponding L-shaped base 1 and is connected to the output end of the servo motor 22. A coupling is installed at the connection between the servo motor 22 and the lead screw 21; a nut seat 23 is threaded onto the lead screw 21; a lifting cylinder 24 is vertically fixed at the bottom of the nut seat 23; guide blocks 25 are vertically fixed on the two opposite outer walls of the lifting cylinder 24; and the two guide blocks 25 are slidably mounted on the corresponding guide rods 12.

[0050] An external PLC controller synchronously controls the feed speed of the servo motor 22 and the downward pressure of the lifting cylinder 24;

[0051] The cutting assembly also includes a drive motor 33 vertically fixedly mounted on the outer wall of the cutting seat 31, with its output end fixedly connected to the center of one side of the cutting blade 32. The extrusion fixing assembly also includes L-shaped fixing seats 41 fixedly mounted on both sides of the cutting seat 31. A base 42 is fixedly mounted on the bottom of each of the two L-shaped fixing seats 41. Two springs 47 are installed between each base 42 and its corresponding extrusion seat 43. The spring 47 has an elastic coefficient of 5-10 N / mm, adaptable to strip thicknesses of 0.02-0.1 mm. Each of the two springs 47 contains an insert 48 and an insert rod 49 that interlock with each other. The outer wall of cylinder 8 has an air inlet and outlet hole through the inner cavity. During the extension and retraction of the insert rod 49 inside the insert cylinder 48, the internal pressure of the insert cylinder 48 is maintained through the air inlet and outlet hole. Both insert cylinders 48 are vertically fixedly installed on the top of the corresponding extrusion seat 43. Both insert rods 49 are vertically fixedly installed on the bottom of the base 42. Two rotating rollers 44 and several support rollers 45 are rotatably installed on the two opposite inner side walls of the two extrusion seats 43. Two transmission belts 46 are respectively wrapped around the outer roller wall of the corresponding two rotating rollers 44. The bottom of the several support rollers 45 are in rolling contact with the inner ring wall of the corresponding transmission belts 46.

[0052] The remaining structure is the same as that in Example 1.

[0053] The working process of the novel adjustable cross-cutting machine for amorphous composite strip described in this utility model is as follows:

[0054] Equipment preparation stage

[0055] Fix the two L-shaped bases 1 to the work platform with screws 11 and adjust the levelness.

[0056] The amorphous composite strip is inserted from the feed end and laid flat between the two drive belts 46.

[0057] Strip positioning and pre-compression

[0058] Start the lifting cylinder 24 to push the cutting seat 31 down to the working height. At this time, the extrusion seat 43 moves downward under the action of the spring 47, so that the transmission belt 46 contacts the surface of the strip and applies appropriate pre-tightening force.

[0059] The support roller 45 ensures that the drive belt 46 and the contact surface of the strip are evenly stressed, avoiding excessive local pressure that could cause the strip to deform.

[0060] Cutting and synchronous conveying

[0061] The servo motor 22 drives the lead screw 21 to rotate, which in turn moves the nut seat 23 and the cutting seat 31 along the guide rod 12 to the cutting start position.

[0062] The drive motor 33 starts, driving the cutting blade 32 to rotate at high speed (the speed is adjustable, with a typical value of 2000 rpm).

[0063] When the cutting blade 32 moves down to cut into the strip, the drive belts 46 on both sides operate synchronously under the drive of the rotating roller 44, and their linear speed matches the cutting feed speed (e.g., 0.3-0.8 m / s) to ensure that the strip is transported smoothly during the cutting process.

[0064] Dynamic pressure regulation

[0065] When the cutting blade 32 contacts the strip, the extrusion seat 43 will move slightly upward to compress the spring 47 due to the cutting resistance, and the insertion rod 49 will slide inside the insertion cylinder 48 to buffer the impact force, thereby achieving dynamic pressure adjustment.

[0066] The flexible contact of the drive belt 46 avoids the indentations caused by traditional rigid pressure plates, while its operating characteristics effectively reduce frictional damage between the belt and the stationary components.

[0067] Cutting completed and repositioned

[0068] After the cutting blade 32 completely cuts the strip, the lifting cylinder 24 raises the cutting seat 31 to a safe height.

[0069] Servo motor 22 reverses, driving cutting base 31 back to its initial position, ready for the next cut.

[0070] The drive belt 46 operates continuously, transporting the cut strip segments to the discharge end, while new strip segments are automatically pulled into the processing area.

[0071] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
