Description

Technical Field

[0001] This utility model belongs to the field of material trough processing technology, specifically a precision cutting device for material trough of a forming machine. Background Technology

[0002] In the field of metal processing, especially in the manufacturing of forming machine feed tanks, laser cutting technology is widely used due to its high precision and high efficiency. This technology achieves cutting by melting materials with a high-energy laser beam, and its cutting effect directly depends on the precise matching between laser energy and the moving speed of the workpiece (such as a steel plate).

[0003] However, existing technologies face significant technical bottlenecks in practical applications, primarily in the precise control of cutting speed. Specifically, steel plates of different thicknesses exhibit significant differences in their absorption and penetration requirements for laser energy. Cutting thicker steel plates requires a longer dwell time (i.e., laser action time), necessitating a corresponding reduction in the plate's moving speed to ensure cutting quality; conversely, a faster moving speed can be achieved when cutting thinner plates.

[0004] Currently, the movement of steel plates in trough cutting equipment mainly relies on servo motors or stepper motors. Motor speed control typically depends on adjusting the input current or voltage. However, this control method inherently suffers from discreteness and nonlinearity: primarily, current or voltage adjustments are usually made in stepwise increments of a few amperes or volts. This discontinuous and imprecise adjustment method cannot achieve smooth, continuous, and minute adjustments to the motor speed.

[0005] The aforementioned problems prevent existing equipment from achieving a real-time, precise match between the cutting movement speed and the theoretically optimal cutting speed when cutting steel plates of varying thicknesses. The consequences are as follows: excessive speed may result in incomplete cutting (especially of thick plates) or increased burrs; excessive speed leads to overheating and expansion of the melting zone, an increased heat-affected zone, or even excessive ablation, affecting the dimensional accuracy of the cutting groove and the quality of the edges. Utility Model Content

[0006] This invention provides a precision cutting device for the material trough of a forming machine, which addresses the deficiencies in the prior art.

[0007] This utility model is achieved through the following technical solution:

[0008] A precision cutting device for a forming machine material trough includes an operating table, a laser cutter fixedly mounted vertically on the operating table, several drive gears of different diameters, and a drive motor detachably and vertically connected to the drive gears. The operating table has a horizontally oriented slot, within which are a left clamping rod and a right clamping rod. The right clamping rod is fixedly connected to the left clamping rod via a telescopic rod. A clamping plate is fixedly connected to the top surface of both the left and right clamping rods, located on the operating table. The right clamping rod has a horizontally oriented threaded hole, within which a horizontal lead screw is threaded. The horizontal lead screw passes through a support rod and is rotatably connected to the support rod via a bearing. The support rod is vertically mounted on a base plate. The operating table is fixedly mounted above the base plate. A driven gear meshing with the drive gear is fixedly sleeved on the horizontal lead screw. The drive motor is driven to move longitudinally and lock via a longitudinal moving mechanism.

[0009] In use, the steel plate with the measured cutting position is first placed on the operating table between the clamping plates. The telescopic rod is then extended to move the right clamping rod towards the left clamping rod, thus securing the clamping plates. It is crucial to ensure the cutting trajectory is below the laser cutting machine. The purpose of clamping the steel plate is to prevent longitudinal movement during lateral movement; therefore, excessive clamping force is unnecessary. Next, the appropriate drive gear is selected based on the steel plate thickness and mounted on the drive motor. The drive motor is moved via a longitudinal movement mechanism, causing the drive gear to mesh with the driven gear. The drive motor is then started and adjusted to the corresponding current or voltage (the appropriate gear, current, or voltage for different steel plate thicknesses is determined beforehand). Finally, the laser cutting machine is turned on. The rotation of the drive motor shaft drives the drive gear, which in turn drives the driven gear, which in turn rotates the transverse lead screw. The rotation of the transverse lead screw moves the left clamping rod, which in turn moves the left clamping rod and the right clamping plate synchronously, thus achieving precise cutting of the steel plate.

[0010] Preferably, the longitudinal moving mechanism includes a longitudinal slide rail fixedly connected to the operating table, a slider on the longitudinal slide rail, a movable plate fixedly connected to the slider, a drive motor fixedly mounted on the movable plate, a lower vertical plate fixedly connected to the bottom surface of the movable plate, a longitudinal threaded hole on the lower vertical plate with a longitudinal lead screw threaded into the hole, and a lower fixed plate vertically connected to the top surface of the bottom plate. The longitudinal lead screw and the lower fixed plate are rotatably connected via bearings. Rotating the transverse lead screw causes the slider to move longitudinally, which in turn causes the movable plate to move longitudinally, thus realizing the longitudinal movement of the drive motor.

[0011] Preferably, the movable plate is further provided with a lateral moving mechanism, which includes a slide rail laterally opened on the top surface of the movable plate, a sliding block slidably fitted on the slide rail, a connecting plate fixedly connected to the top surface of the sliding block, a drive motor fixedly mounted on the connecting plate, an upper vertical plate fixedly connected to the bottom surface of the connecting plate, a screw hole laterally opened on the upper vertical plate, a screw threaded into the screw hole, and an upper fixed plate vertically connected to the top surface of the movable plate. The screw is rotatably connected to the upper fixed plate through a bearing. Rotating the screw can drive the sliding block to move laterally, realizing lateral fine adjustment of the drive motor and ensuring better meshing between the driving gear and the driven gear.

[0012] Preferably, the drive motor's shaft is coaxially fixedly connected to an outer sleeve, and the drive gear is vertically connected to an inner rod that can be inserted into the outer sleeve. The outer sleeve has several threaded holes evenly distributed along its circumference, and the inner rod has blind holes that correspond one-to-one with the threaded holes along its circumference, with internal threads inside the blind holes. A connecting screw passes through the threaded holes and enters the blind holes. The cooperation between the outer sleeve and the inner rod enables a detachable and fixed connection between the drive gear and the drive motor, and the evenly distributed connecting screws along the circumference of the outer sleeve ensure more even force distribution during rotation.

[0013] Preferably, rubber pads are fixedly provided on the opposite surfaces of the clamping plates. The rubber pads can increase the friction between the clamping plates and the steel plates, further preventing longitudinal movement of the steel plates and ensuring the accuracy of cutting.

[0014] The beneficial effects of this utility model are as follows: By replacing the drive gear with a different size, the rotational speed of the driven gear can be further adjusted, thereby achieving a more precise adjustment of the steel plate moving speed. This avoids the steel plate being cut too fast, resulting in incomplete cutting (especially thick plates) or an increase in burrs; and avoids the material being overheated and melting, expanding the heat-affected zone, or even being excessively ablated due to the speed being too slow, which affects the dimensional accuracy of the material trough and the edge quality.

[0020] 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 embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] A precision cutting device for the material trough of a forming machine, such as Figure 1 and Figure 2 As shown, the system includes an operating table 15, a vertical beam connected vertically upwards on one side of the operating table, a laser cutting machine 5 fixedly mounted downwards on the upper end of the vertical beam, several drive gears 9 of different diameters, and a drive motor 7 detachably and vertically connected to the drive gears 9. The operating table 15 has a horizontally oriented slot, within which are a left clamping rod 2 and a right clamping rod 3. The right clamping rod 3 is fixedly connected to the left clamping rod 2 via a telescopic rod 14. The top surfaces of both the left and right clamping rods 2 are fixedly connected to clamping plates 4 located on the operating table 15. The right clamping rod 3 has a horizontally oriented threaded hole, within which a horizontal threaded rod 6 is threaded. The horizontal threaded rod 6 passes through a support rod and is rotatably connected to the support rod via a bearing. Specifically, the support rod has a horizontally oriented through hole, within which a bearing is fixedly mounted. The horizontal threaded rod 6 passes through the inner ring of the bearing and is welded to the inner ring of the bearing. The support rod is vertically mounted on a base plate 1. The horizontal threaded rod 6 is fixedly sleeved with a driven gear 8 that meshes with the drive gears 9. The drive motor 7 is driven to move longitudinally and lock via a longitudinal moving mechanism.

[0022] In use, the steel plate with the measured cutting position is first placed between the clamping plates 4. The telescopic rod 14 is then extended to move the right clamping rod 3 towards the left clamping rod 2, thus clamping the clamping plates 4. It is crucial to ensure the cutting trajectory is below the laser cutting machine 5. The purpose of clamping the steel plate is to prevent longitudinal movement during lateral movement; therefore, excessive clamping force is unnecessary. Next, the appropriate drive gear 9 is selected based on the steel plate thickness and mounted on the drive motor 7. The drive motor 7 is moved via a longitudinal movement mechanism, causing the drive gear 9 to mesh with the driven gear 8. The drive motor 7 is then started and adjusted to the corresponding current or voltage (the appropriate gear, current, or voltage for different steel plate thicknesses is determined beforehand). Finally, the laser cutting machine 5 is turned on. The rotation of the drive motor 7 shaft drives the drive gear 9, which in turn drives the driven gear 8, which in turn drives the transverse lead screw 6. The rotation of the transverse lead screw 6 moves the left clamping rod 2, which in turn moves the left clamping rod 2 and the right clamping plate 4 synchronously, thus achieving precise cutting of the steel plate.

[0023] The longitudinal moving mechanism includes two parallel longitudinal slide rails fixedly connected to the base plate 1. A slider is mounted on each longitudinal slide rail, and a moving plate 11 is fixedly connected to the slider. A drive motor 7 is fixedly mounted on the moving plate 11. A lower vertical plate is fixedly connected to the bottom surface of the moving plate 11, and a longitudinal threaded hole is formed on the lower vertical plate, with a longitudinal lead screw 10 threaded into the hole. A lower fixed plate is vertically connected to the top surface of the base plate 1, and the longitudinal lead screw 10 is rotatably connected to the lower fixed plate via a bearing. Rotating the transverse lead screw 6 causes the slider to move longitudinally, which in turn causes the moving plate 11 to move longitudinally, thus realizing the longitudinal movement of the drive motor 7.

[0024] The movable plate 11 is also equipped with a lateral moving mechanism, which includes slide rails laterally opened on both sides of the top surface of the movable plate 11. Sliding blocks are slidably fitted on the slide rails, and a connecting plate is fixedly connected to the top surface of the sliding blocks. The drive motor 7 is fixedly mounted on the connecting plate. An upper vertical plate is fixedly connected downwards to the bottom surface of the connecting plate. The upper vertical plate has a threaded hole laterally opened, and a screw is threaded into the threaded hole. An upper fixed plate is vertically connected upwards to the top surface of the movable plate 11. The screw is rotatably connected to the upper fixed plate via a bearing. Rotating the screw can drive the sliding blocks to move laterally, achieving fine-tuning of the drive motor 7 laterally and ensuring better meshing between the driving gear 9 and the driven gear 8.

[0025] The drive motor 7 has an outer sleeve 12 coaxially fixedly connected to its rotating shaft. The drive gear 9 is vertically connected to an inner rod 13 that can be inserted into the outer sleeve 12. The outer sleeve 12 has several threaded holes evenly distributed around its circumference. The inner rod 13 has blind holes that correspond one-to-one with the threaded holes, and the blind holes have internal threads. A connecting screw passes through the threaded holes and enters the blind holes. The cooperation between the outer sleeve 12 and the inner rod 13 enables a detachable and fixed connection between the drive gear 9 and the drive motor 7. The evenly distributed connecting screws around the outer sleeve 12 ensure more even force distribution during rotation.

[0026] Rubber pads are fixedly provided on the opposite surfaces of the clamping plate 4. The rubber pads can increase the friction between the clamping plate 4 and the steel plate, further preventing longitudinal movement of the steel plate and ensuring the accuracy of cutting.

[0027] The specific method of the rotational connection between the longitudinal lead screw 10 and the lower fixed plate, and between the screw and the upper fixed plate is as follows: the corresponding longitudinal lead screw 10 and screw are inserted into the inner ring of the bearing and are coaxial with and fixedly connected to the inner ring of the bearing. The upper fixed plate and the lower fixed plate are provided with round holes, and the outer ring of the bearing is coaxial and fixedly installed in the corresponding round holes.

[0028] The use of this application allows for further adjustment of the rotational speed of the driven gear 8 by replacing the drive gear 9 with one of different sizes, thereby enabling more precise adjustment of the steel plate's moving speed. This avoids situations where the steel plate is cut too quickly, resulting in incomplete cutting (especially of thick plates) or increased burrs; or where the material is cut too slowly, leading to an expansion of the overheated melting zone, an increase in the heat-affected zone, or even excessive ablation, which affects the dimensional accuracy of the material trough and the quality of the edges.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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 do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
