Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, in particular to a kitchenware steel plate blanking device and a blanking method based on laser cutting. Background Art

[0002] Laser cutting has the advantages of high precision and quality, high efficiency and automation, small impact of hot zones, and non-contact processing, which can meet diverse processing needs. Before the production of kitchen and bathroom furniture (sinks, cabinets, etc.), laser cutting equipment is usually used to laser cut the kitchenware steel plate raw materials into specified shapes. Therefore, the application of laser cutting is becoming more and more popular.

[0003] For example, the Chinese invention patent application with publication number CN118371835A discloses a blanking device for processing and producing thick steel plates for steel structures. This type of blanking device, after placing the steel plate on the cutting table, drives the No. 1 connecting frame and the arc-shaped slider to rotate through the No. 1 motor, thereby switching the cutting flame cutting machine, plasma cutting machine and laser cutting machine according to demand, so that the cutting mechanism can meet the blanking needs of steel plates with different cutting accuracy requirements. While ensuring the cutting accuracy, it can also reduce the cost of blanking.

[0004] For example, the Chinese invention patent application with publication number CN119589425B discloses a multifunctional aluminum processing all-in-one machine. This type of device places the aluminum material to be processed on a sword grid, cuts it using a laser cutting mechanism, and after cutting, sends the workpieces into a box in batches and neatly, performs autonomous center positioning, and then performs grinding processing. This solves the problem in the prior art that the workpieces need to be manually collected after being cut before they can be transferred to the grinding equipment for grinding processing.

[0005] However, due to the carbonization of oil, oxides or coatings on the surface of metal materials at high temperatures to form particles, as well as materials such as aluminum and stainless steel with low melting points or prone to producing sticky slag, laser cutting equipment produces impurities such as cutting ash when laser cutting metal plates. The impurities often adhere to the sword grid due to viscosity, and are completely solidified on the sword grid under repeated heating at high temperature during laser cutting. The adhesion and accumulation of cutting ash causes the metal material to be placed unevenly, affecting the cutting accuracy. Moreover, when too much cutting ash adheres, the sword grid needs to be replaced from time to time, resulting in increased costs. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a kitchenware steel plate blanking device and method based on laser cutting, which solves the problems raised in the background art.

[0025] On the other hand, the present invention also provides a method for cutting kitchen steel plates based on laser cutting, comprising the following steps:

[0026] Step 1: After the laser cutting of the steel plate on the sword grille plate is completed, the friction grid plate is stepped and displaced, and relative friction displacement occurs with the two sides of the sword grille plate to frictionally clean the cutting dust on both sides of the sword grille plate. After friction cleaning, the stepping displacement state is maintained to push the steel plate on the sword grille plate to displace and unload;

[0027] Step 2: While the friction grid plate lifts the steel plate on the sword grille plate step by step, the two adjacent groups of sword grille plates are rubbed against each other in turn to clean the cutting dust between the teeth of the sword grille plates.

[0028] The present invention has the following beneficial effects:

[0029] (1) After the laser cutting of the kitchen steel plate, the device for unloading the kitchen steel plate by laser cutting, through the braking of the driving source, on the one hand, pushes the friction grid plate to move relative to the sword grid plate in a step-by-step manner, so as to realize the friction cleaning of the cutting dust on both sides of the sword grid plate and the step-by-step pushing and unloading of the steel plate on the sword grid plate; on the other hand, when the steel plate on the sword grid plate is unloaded in a step-by-step manner, it also pushes the sword grid plate to clean itself by friction, so as to clean the cutting dust in time, avoid the cutting dust from sticking and being retained, affecting the subsequent cutting quality and the replacement cost caused by the need for irregular replacement.

[0030] (2) The laser-cut kitchen steel plate unloading device pushes the friction grid plate to move relative to the sword grid plate by braking the step-by-step pushing structure in the driving source. The friction grid plate is pushed in step by step to make friction contact with both sides of the sword grid plate, and the cutting dust generated by laser cutting adhesion on both sides of the sword grid plate is cleaned by friction. After friction cleaning, the continuous step-by-step movement of the friction grid plate can also be used as a pushing component to push the steel plate on the sword grid plate step by step to unload. The staff only needs to stand at the unloading end to complete the unloading, and there is no need to climb onto the cutting table to pick up the material one by one, thereby improving the operation safety.

[0031] (3) The laser-cut kitchenware steel plate unloading device, through the promotion of the staggered propulsion structure in the driving source, pushes the sword grille plate to move relative to another group of plates by friction while the friction plate lifts the steel plate on the sword grille plate step by step to unload the steel plate, and performs staggered friction cleaning on the cutting dust between the teeth of the sword grille plate, thereby further improving the cleaning efficiency of the cutting dust. At the same time, due to the step-by-step lifting of the steel plate, its self-friction displacement will not contact the steel plate and cause scratches on the steel plate.

[0032] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] See also Figures 1-15 The embodiment of the present invention provides a technical solution: a kitchenware steel plate blanking device and blanking method based on laser cutting,

[0051] See also Figure 1-Figure 3 The kitchen steel plate blanking device based on laser cutting includes a casing 1, an X-axis guide rail 2 is provided above the frame of the casing 1, a Y-axis guide rail 3 is provided on the upper side of the slide of the X-axis guide rail 2, a Z-axis guide rail 4 is provided on the slide of the Y-axis guide rail 3, and a laser cutting gun 5 is provided on the slide of the Z-axis guide rail 4. Based on the three-way driving structure composed of the X-axis guide rail 2, the Y-axis guide rail 3, and the Z-axis guide rail 4, the laser cutting gun 5 is driven to move in three-dimensional space to cut the kitchen steel plate, and the kitchen steel plate is laser cut into a specified shape and size structure.

[0052] In addition, it also includes a sword grille plate 6, a friction grille 7 and a driving source which are separately arranged in the casing 1. The sword grille plates 6 are in pairs, and each group of sword grille plates 6 fits tightly. The friction grille plates 7 are separately arranged under the sword grille plates 6. The friction grille plates 7 are in pairs and are arranged on both sides of the sword grille plates 6. The driving source is arranged on the moving path of the sword grille plates 6 and the friction grille plates 7, and is used to push the friction grille plates 7 to step relative to the sword grille plates 6 and to push the sword grille plates 6 to stagger relative displacement. The sword grille plates 6 are used as a cutting platform for the kitchen steel plates. After the steel plates are cut, the driving source is used to The drive of the power source, on the one hand, drives the friction grid plate 7 to move step by step, pushing the friction grid plate 7 out from the bottom of the sword grid plate 6, and at the same time, frictionally cleans the cutting dust adhered to both sides of the sword grid plate 6 due to laser cutting. After friction cleaning, the continuous stepping braking of the friction grid plate 7 pushes the steel plate on the sword grid plate 6 to step and unload. On the other hand, while the friction grid plate 7 lifts the steel plate from the sword grid plate 6 step by step, it drives one group of the two groups of sword grid plates 6 to move relative to the other group, and performs self-friction cleaning on the cutting dust between the teeth of the sword grid plate 6 again.

[0053] For details: please refer to Figure 3 、 Figure 5 、 Figure 7-Figure 9In order to achieve friction cleaning of cutting ash on both sides of the sword grid plate 6 and step-by-step unloading of steel plates on the sword grid plate 6, the driving source includes a first power shaft 10 arranged in the displacement path direction of the friction grid plate 7 and a second power shaft 22 arranged away from the first power shaft 10. A step-by-step driving structure is provided between the first power shaft 10 and the second power shaft 22, which is used to drive the friction grid plate 7 to step relative to the sword grid plate 6. The step-by-step driving structure includes a driving motor 9 arranged on the casing 1, and a driving shaft 19 is provided at the output end of the driving motor 9. The driving shaft 19 and the first power shaft 10 are kept in meshing drive through a transmission combination of a transmission worm 20 and a transmission worm wheel 21. The driving shaft 19 is used to drive the first power shaft 10 to generate a step-by-step driving thrust.

[0054] As a further solution of this embodiment, a cam 23 is coaxially provided on the first power shaft 10, and an eccentric slide 24 is slidingly provided above the cam 23, and a support rod 25 is provided above the eccentric slide 24. The other end of the support rod 25 is provided with a support frame 17 for supporting the friction grid plate 7. When the first power shaft 10 rotates, the cam 23 is driven to rotate, and the cam 23 is used to apply a support thrust to the eccentric slide 24, pushing the support rod 25 up, and then applying a support thrust to the friction grid plate 7 through the support frame 17, pushing the friction grid plate 7 up, and rubbing against the two sides of the sword grid plate 6, frictionally cleaning the cut ash on both sides of the sword grid plate 6, and due to the sliding setting of the cam 23 and the eccentric slide 24, the eccentric slide 24 and the cam 23 maintain a sliding transmission state, and then the support rod 25 synchronously maintains the stepping displacement capability.

[0055] Furthermore, a guide sleeve 26 is provided at one end of the second power shaft 22, and the guide sleeve 26 slides outside the top support rod 25. A stepping sleeve 27 is provided on the first power shaft 10, and a first stop slot 28 is provided on the outer wall of one end of the stepping sleeve 27, and a second stop slot 30 is provided on the outer wall of the other end of the stepping sleeve 27. Two sets of stepping slots 29 are provided in the middle of the stepping sleeve 27, and both ends of the first stop slot 28 are connected to the corresponding end of the second stop slot 30 through the stepping slot 29. A push rod 32 is provided in the radial direction of the second power shaft 22, and the other end of the push rod 32 is provided with a first stop slot 28 and a stepping slot 29. , the slider 31 that slides in the second stop slot 30, while the first power shaft 10 rotates, drives the stepping sleeve 27 to rotate synchronously, so that the slider 31 slides along the first stop slot 28, the stepping slot 29, and the second stop slot 30. While the slider 31 slides along the slot on the stepping sleeve 27, the rotational force of the first power shaft 10 is converted into a horizontal thrust, which is transmitted to the second power shaft 22 through the propulsion rod 32, and a horizontal thrust is applied to the top support rod 25 in the guide sleeve 26, so that the top support rod 25 moves upward while maintaining horizontal movement, forming a stepping movement thrust, which pushes the steel plate on the sword grid plate 6 to step forward and unload.

[0056] It should be noted that the first stop slot 28, the stepping slot 29, and the second stop slot 30 form a closed loop. The first stop slot 28 and the second stop slot 30 are arc structures that are staggered and symmetrically arranged, and the stepping slot 29 is a spiral structure. Through the closed loop formed by the first stop slot 28, the stepping slot 29, and the second stop slot 30, the slider 31 slides back and forth along the three groups of slots, applying a horizontal thrust to the friction grid 7, and under the lifting and lowering push of the cam 23 on the eccentric slide 24, a synchronous lifting thrust is applied to the friction grid 7, thereby forming a reciprocating stepping thrust. In addition, when the slider 31 slides along the first stop slot 28 of the arc structure, it only maintains a horizontal sliding state and does not apply a horizontal thrust. At this time, the cam 23 is pressed against the friction grid 7 applies an upward thrust alone to push out the friction grid plate 7 and frictionally displace the sword grid plate 6, and frictionally clean the cut ash on both sides of the sword grid plate 6. Synchronously, when the slider 31 slides to the stepping slide 29 of the spiral structure, a horizontal thrust is applied to make the friction grid plate 7 with the top support displacement maintain the horizontal displacement synchronously, forming a step-forward state, and step-by-step lifting and pushing the steel plate on the sword grid plate 6, and the steel plate is pushed step by step to unload, and then when the slider 31 slides to the second stop slide 30 of the arc structure, the horizontal thrust on the friction grid plate 7 is released again. At this time, the friction grid plate 7 moves downward with the deflection of the cam 23 and brakes, and under the sliding combination of another set of stepping slides 29 and the slider 31, a reverse horizontal thrust is applied to drive the friction grid plate 7 to reset, thereby forming a repetitive stepping thrust.

[0057] See also Figure 3-Figure 4 、 Figure 6-Figure 15In order to realize the self-friction cleaning and dust removal of the sword grille plate 6, the driving source also includes a staggered propulsion structure provided between the second power shaft 22 and the arm force frame 14, which is used to drive the friction grid plate 7 to step and lift the steel plate, and then the sword grille plate 6 self-friction displacement, wherein the staggered propulsion structure includes a reciprocating support arm 11 provided at the other end of the second power shaft 22, and the top of the reciprocating support arm 11 is provided with a propulsion seat structure 12 composed of a support plate 121, a compression spring 122, and a push platform 123, and ... When the second power shaft 22 drives the reciprocating support arm 11 to move synchronously, the reciprocating support arm 11 drives the pushing platform 123 to approach the pressure platform 133 in sequence. When it contacts the first group of pressure platforms 133, a horizontal thrust is applied to the first group of pressure platforms 133, and the thrust is transmitted to one group of sword grille plates 6, so that the sword grille plates 6 are frictionally displaced relative to the other group, and the cutting dust between the tooth gaps of the sword grille plates 6 is frictionally cleaned. When the horizontal thrust overcomes the elastic compression force of the compression spring 122, the pushing platform 123 moves downward and is displaced away from the first group of pressure platforms 133. After being completely displaced, it is restored by the elastic compression of the compression spring 122 and contacts the second group of pressure platforms 133 again to push, and the thrust is transmitted to the other group of sword grille plates 6, forming a relative friction displacement state again, and the cutting dust between the tooth gaps of the sword grille plates 6 is again cleaned. Friction cleaning, and when the subsequent pushing platform 123 is reset in the opposite direction along the pressure platform 133, the pressure platform 133 is rotated and connected to the support platform 131 under the action of the rotating pin 132, so that the pushing platform 123 pushes the pressure platform 133 to rotate and make way, and after the pressure platform 133 rotates and makes way, the tension spring 134 is used to pull the pressure platform 133 to reset, and it is close to the support platform 131, and the support platform 131 is used to limit its rotation state, so that the pressure platform 133 maintains a unidirectional force state.

[0058] As a further solution of this embodiment, one end of the sword grille plates 6 is provided with a first support shaft 15 in a group of two. Both groups of first support shafts 15 are half-missing shaft structures. The first support shaft 15 is provided with a first shaft seat 16 that supports its guide along its axial direction, and the two groups of first support shafts 15 are staggered along their axial directions with arm force frames 14 connected to each other. When the two groups of pressure-bearing seat structures 13 are successively subjected to the thrust of the propulsion seat structure 12, the thrust is transmitted to the first support shaft 15 connected thereto through the arm force frame 14, so that the first support shaft 15 slides relative to the other group, and then one group of sword grille plates 6 is staggeredly displaced relative to the other group of sword grille plates 6 to perform self-friction cleaning and dust removal.

[0059] Furthermore, the other end of the sword grille plate 6 is provided with a second support shaft 35 in a group of two. Both groups of second support shafts 35 are half-missing shaft structures. The second support shaft 35 is provided with a second shaft seat 18 along its axial direction to support its guide. One end of one group of second support shafts 35 is provided with a propulsion sleeve 36 for applying pressure to the first return spring 37, and one end of the other group of second support shafts 35 is provided with a brake handle 38 for applying pressure to the second return spring 39. When the sword grille plate 6 is staggered relative to the other group, its thrust drives the second support shaft 35 to slide relative to the other group, and then the propulsion sleeve 36 applies pressure to the first return spring 37 or the brake handle 38 applies pressure to the second return spring 39 separately, so that the sword grille plate 6 is reset after the staggered displacement, maintaining the relative staggered displacement state of the sword grille plate 6.

[0060] In addition, the sliding contact surfaces of the push platform 123 and the pressure platform 133 are both inclined structures. The contact displacement trajectory of the push platform 123 along the two groups of pressure platforms 133 is located in the sliding trajectory of the slider 31 along the stepping groove 29. By setting the push platform 123 and the pressure platform 133 as an inclined structure, the two are kept in a staggered pushing state, and by setting the contact displacement trajectory of the push platform 123 along the pressure platform 133 in the sliding trajectory of the slider 31 along the stepping groove 29, when the slider 31 slides along the stepping groove 29, the friction grid 7 will step and lift the steel plate on the sword grid plate 6, and the steel plate and the sword grid plate 6 will remain in a separated state, so that when the push platform 123 and the pressure platform 133 push the sword grid plate 6 to staggered displacement, the displacement of its sword teeth will not scratch and damage the steel plate.

[0061] It should be noted that a give-way chute 33 is provided above the drive housing 8 to provide displacement for the guide sleeve 26, and a cover 34 is provided on the top of the guide sleeve 26 to close the give-way chute 33. The setting of the give-way chute 33 provides displacement space for the guide sleeve 26 to push the top support rod 25 to move horizontally, so that the top support rod 25 has both lifting and horizontal displacement states. The setting of the cover 34 closes the give-way chute 33 to prevent impurities such as cutting dust from falling into the drive housing 8 through the give-way chute 33 and affecting its transmission efficiency.

[0062] When in use (working), the kitchen steel plate to be cut is placed on the cutting platform composed of the sword grid plate 6, and then based on the three-way braking drive structure composed of the X-axis guide rail 2, the Y-axis guide rail 3, and the Z-axis guide rail 4, the laser cutting gun 5 is driven to move in three directions to cut and blank the kitchen steel plate.

[0063] After the cutting and unloading is completed, based on the drive of the driving motor 9, the first power shaft 10 is driven to rotate to generate thrust. While the first power shaft 10 rotates, the cam 23 is driven to rotate, and the eccentric rotation of the cam 23 is used to apply a supporting thrust to the friction grid plate 7, which rubs against the two sides of the sword grid plate 6, and performs a friction cleaning process on the cut ash on both sides of the sword grid plate 6. The first power shaft 10 synchronously drives the stepping shaft sleeve 27 to rotate, so that the slider 31 slides along the first stop slot 28, the stepping slot 29, and the second stop slot 30 on the stepping shaft sleeve 27, and converts the rotational force of the first power shaft 10 into a horizontal thrust and transmits it to the second power shaft 22, applying a horizontal thrust to the friction grid plate 7, so that the friction grid plate 7 is supported and displaced at the same time as horizontal displacement, forming a stepping pushing state, and the steel plate on the sword grid plate 6 is pushed forward and unloaded.

[0064] And while the steel plate is pushed forward step by step to be unloaded, the second power shaft 22 drives the reciprocating support arm 11 to move synchronously. While the friction grid plate 7 lifts the steel plate step by step, the pushing seat structure 12 is alternately subjected to force with the two groups of pressure seat structures 13 in turn, and the braking thrust is transmitted to the two adjacent groups of sword grid plates 6 through the arm force frame 14 in turn, so that one group of sword grid plates 6 is staggered relative to the other group of sword grid plates 6 for self-friction cleaning and dust removal. Then, according to this state, the cutting dust on the sword grid plate 6 is cyclically friction-cleaned and dust-removed, while the steel plate on the sword grid plate 6 is stepped forward and unloaded, without the need for manpower to climb up the cutting table to take the material and unload it one by one.

[0065] On the other hand, the present invention also provides a method for cutting kitchen steel plates based on laser cutting, comprising the following steps:

[0066] Step 1: After the laser cutting and unloading of the steel plate on the sword grille plate 6 is completed, the friction grid plate 7 is stepped and displaced relative to the two sides of the sword grille plate 6 to frictionally clean the cutting dust on both sides of the sword grille plate 6. After friction cleaning, the stepping displacement state is maintained to push the steel plate on the sword grille plate 6 to displace and unload;

[0067] Step 2: While the friction grid plate 7 lifts the steel plate on the sword grille plate 6 step by step, the two adjacent groups of sword grille plates 6 rub against each other in turn, and the cutting dust between the teeth of the sword grille plates 6 is rubbed and cleaned.
