Description

Technical Field

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

[0002] Laser cutting has the advantages of high precision and quality, high efficiency and automation, small influence of the heat zone, non-contact processing, etc., meeting diverse processing requirements. Before the production of kitchen and bathroom furniture (such as washbasins, cabinets, etc.), the raw material of kitchenware steel plates is usually laser cut into specified shapes by laser cutting equipment. Therefore, the application of laser cutting is becoming more and more popular.

[0003] For example, the Chinese patent application with the publication number CN118371835A discloses a blanking device for the processing and production of thick steel plates of steel structures. For such a blanking device, after the steel plate is placed on the cutting table, the first motor drives the first connecting frame and the arc-shaped slider to rotate, so as to switch the flame cutting machine, plasma cutting machine and laser cutting machine for cutting according to requirements, so that the cutting mechanism can meet the blanking requirements of steel plates with different cutting precision requirements. On the premise of ensuring the cutting precision, the blanking cost can also be reduced.

[0004] Another example is the Chinese patent application with the publication number CN119589425B, which discloses a multi-functional aluminum processing integrated machine. Such a device places the aluminum to be processed on the sword grid, cuts it with a laser cutting mechanism, and after cutting, batches and neatly sends the workpieces into the box for self-centering positioning and then grinding and processing, solving the problem in the prior art that after the workpieces are cut, they need to be manually collected and then transferred to the grinding equipment for grinding.

[0005] However, due to the formation of particles by the carbonization of oil stains, oxides or coatings on the surface of metal materials at high temperatures, and materials with low melting points or easy to produce viscous slag such as aluminum and stainless steel, the laser cutting equipment generates impurities such as cutting ash when laser cutting metal plates. The impurities often adhere to the sword grid due to the viscous effect and are completely solidified on the sword grid under the repeated heating of the high temperature of laser cutting. The adhesion and accumulation of cutting ash cause the metal material to be placed unevenly, affecting the cutting accuracy. Moreover, after too much cutting ash adheres, the sword grid needs to be replaced irregularly, resulting in an increase in cost. Summary of the Invention

[0016] On the other hand, the present invention also provides a method for cutting kitchen steel plates based on laser cutting, comprising the following steps: Step 1: After the laser cutting of the steel plate on the sword grille plate is completed, the friction grille 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; 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 tooth gaps of the sword grille plates.

[0017] The present invention has the following beneficial effects: (1) After the laser cutting of the kitchenware steel plate for blanking, through the braking of the driving source, on the one hand, it pushes the friction grid plate to make a step displacement relative to the sword grid plate, realizing the friction cleaning of the cutting ash 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.

[0023] Please refer to Figures 1 - 15 , an embodiment of the present invention provides a technical solution: a kitchenware steel plate blanking device and a blanking method based on laser cutting, On the one hand, the present invention provides a kitchenware steel plate blanking device based on laser cutting, Please refer to Figures 1 - 3, a kitchenware steel plate blanking device based on laser cutting, includes a machine shell 1. Above the frame of the machine shell 1, there is an X-axis guide rail 2. On the upper side of the slide table of the X-axis guide rail 2, there is a Y-axis guide rail 3. On the slide table of the Y-axis guide rail 3, there is a Z-axis guide rail 4. On the slide table of the Z-axis guide rail 4, there is a laser cutting gun 5. Based on the three-way drive structure formed by the X-axis guide rail 2, Y-axis guide rail 3, and Z-axis guide rail 4, the laser cutting gun 5 is driven to move in three-dimensional space to cut the kitchenware steel plate and blank the kitchenware steel plate into a specified shape and size structure.

[0024] In addition, it also includes a sword grid plate 6, a friction grid plate 7, and a drive source that are separately installed in the machine shell 1. The sword grid plates 6 are in pairs, and each pair of sword grid plates 6 is closely attached. The friction grid plate 7 is separately installed below the sword grid plate 6. The friction grid plates 7 are in pairs and are arranged on both sides of the sword grid plate 6. The drive source is arranged on the moving path of the sword grid plate 6 and the friction grid plate 7, and is used to push the friction grid plate 7 to make a step displacement relative to the sword grid plate 6 and push the sword grid plate 6 to make a relative staggered displacement. The sword grid plate 6 is used as the cutting platform for the kitchenware steel plate. After the steel plate cutting is completed, driven by the drive source, on the one hand, the friction grid plate 7 is driven to move step by step, and the friction grid plate 7 is pushed out step by step from the bottom of the sword grid plate 6. While being pushed out, the cutting ash adhered to both sides of the sword grid plate 6 due to laser cutting is frictionally cleaned. After the frictional cleaning, the continuous step braking of the friction grid plate 7 also pushes the steel plate on the sword grid plate 6 to unload step by step. On the other hand, while the friction grid plate 7 steps up the steel plate from the sword grid plate 6, one group of the two groups of sword grid plates 6 is driven to displace relative to the other group to perform a self-frictional cleaning work on the cutting ash in the tooth gaps of the sword grid plate 6 again.

[0025] Specifically: Please refer to Figure 3 , Figure 5 , Figures 7 - 9 , to achieve the frictional cleaning of the cutting ash on both sides of the sword grid plate 6 and the step unloading of the steel plate on the sword grid plate 6, the drive 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. There is a step pushing structure between the first power shaft 10 and the second power shaft 22, which is used to drive the friction grid plate 7 to make a step displacement relative to the sword grid plate 6. Among them, the step pushing structure includes a drive motor 9 arranged on the machine shell 1. The output end of the drive motor 9 is provided with a drive shaft 19. The drive shaft 19 and the first power shaft 10 are kept meshing and driven through the transmission combination of a transmission worm 20 and a transmission worm wheel 21. The drive shaft 19 is used to drive the first power shaft 10 to generate a step driving thrust.

[0026] As a further solution of this embodiment, a cam 23 is coaxially arranged on the first power shaft 10. An eccentric slide 24 is slidably arranged above the cam 23. A top support rod 25 is arranged above the eccentric slide 24. The other end of the top support rod 25 is provided with a top support frame 17 for supporting the friction grating plate 7. While the first power shaft 10 rotates, it drives the cam 23 to rotate. By using the cam 23 to apply a top support thrust to the eccentric slide 24, the top support rod 25 is pushed upward. Then, a top support thrust is applied to the friction grating plate 7 through the top support frame 17, pushing the friction grating plate 7 upward to relatively rub against both sides of the sword grating plate 6, and performing a friction cleaning operation on the cutting ash on both sides of the sword grating plate 6. Moreover, due to the sliding arrangement of the cam 23 and the eccentric slide 24, a sliding transmission state is maintained between the eccentric slide 24 and the cam 23, and then the top support rod 25 synchronously maintains the ability of step displacement.

[0027] Furthermore, a guide sliding sleeve 26 is arranged at one end of the second power shaft 22. The guide sliding sleeve 26 is slidably sleeved outside the top support rod 25. A step shaft sleeve 27 is sleeved on the first power shaft 10. A first stop chute 28 is formed on the outer wall of one end of the step shaft sleeve 27. A second stop chute 30 is formed on the outer wall of the other end of the step shaft sleeve 27. Two groups of step chutes 29 are formed in the middle of the step shaft sleeve 27. Both ends of the first stop chute 28 are communicated with the corresponding one end of the second stop chute 30 through the step chutes 29. A push rod 32 is arranged radially on the second power shaft 22. The other end of the push rod 32 is provided with a sliding buckle 31 that slides along the first stop chute 28, the step chutes 29, and the second stop chute 30. While the first power shaft 10 rotates, it drives the step shaft sleeve 27 to rotate synchronously, causing the sliding buckle 31 to slide along the chute bodies of the first stop chute 28, the step chutes 29, and the second stop chute 30. While the sliding buckle 31 slides along the chutes on the step shaft 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 push rod 32, applying a horizontal thrust to the top support rod 25 in the guide sliding sleeve 26, so that while the top support rod 25 moves upward, it also maintains a horizontal movement, forming a step movement thrust to push the steel plate on the sword grating plate 6 to step forward and discharge materials.

[0028] It should be noted that the first stop chute 28, the stepping chute 29, and the second stop chute 30 form a closed-loop circuit. The first stop chute 28 and the second stop chute 30 are arc-shaped structures arranged in an alternating and symmetrical manner, and the stepping chute 29 is a spiral structure. Through the closed-loop circuit formed by the first stop chute 28, the stepping chute 29, and the second stop chute 30, the sliding buckle 31 reciprocally slides along the three groups of chutes, applying a horizontal thrust to the friction grating 7. Under the lifting and pushing of the cam 23 on the eccentric slide 24, a synchronous lifting thrust is applied to the friction grating 7, thereby forming a reciprocating stepping thrust. In addition, when the sliding buckle 31 slides along the first stop chute 28 of the arc-shaped structure, it only maintains a horizontal sliding state and does not apply a horizontal thrust. At this time, the cam 23 applies a separate upward thrust to the friction grating 7, pushing the friction grating 7 out to frictionally displace with the sword grating 6, and frictionally cleaning the cutting ash on both sides of the sword grating 6. Synchronously, when the sliding buckle 31 slides to the spiral stepping chute 29, a horizontal thrust is applied, causing the friction grating 7 with a top-support displacement to maintain a synchronous horizontal displacement, forming a stepping forward state, and steppingly lifting and pushing the steel plate on the sword grating 6 to steply push the steel plate for discharging. Then, when the sliding buckle 31 slides to the second stop chute 30 of the arc-shaped structure, the horizontal thrust on the friction grating 7 is released again. At this time, the friction grating 7 moves downward and brakes with the deflection of the cam 23, and under the sliding combination of another group of stepping chute 29 and the sliding buckle 31, a reverse horizontal thrust is applied to drive the friction grating 7 to reset, thereby forming a cyclic stepping thrust.

[0029] Please refer to Figures 3 - 4 、 Figures 6 - 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 arranged between the second power shaft 22 and the arm force frame 14, which is used to drive the friction grille plate 7 to step and lift the steel plate to self-frictionally displace the sword grille plate 6, wherein the staggered propulsion structure includes a reciprocating support arm 11 arranged 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 a support plate 121, a compression spring 122, and a push platform 123. The pressure-bearing seat structure 13 composed of a support platform 131, a rotating pin 132, a pressure platform 133, and a tension spring 134, when the second power shaft 22 drives the reciprocating support arm 11 to synchronously move, the reciprocating support arm 11 drives the push platform 123 to approach the pressure platform 133 in sequence, and when contact is made with 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 ash between the tooth gaps of the sword grille plates 6 is frictionally cleaned, and when the horizontal thrust overcomes the elastic compression force of the compression spring 122, the push platform 123 moves downward and is displaced away from the first group of pressure platforms 133, and after complete dislocation, it is restored by the elastic compression of the compression spring 122, and contacts and pushes the second group of pressure platforms 133 again, and the thrust is transmitted to the other group of sword grille plates 6, forming a relative friction displacement state again, and the cutting ash between the tooth gaps of the sword grille plates 6 is again cleaned. Friction cleaning, and when the push platform 123 is subsequently 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 turn pin 132, so that the push 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.

[0030] As a further scheme of the present embodiment, first support shafts 15 are provided at one end of the sword grille plates 6 in groups of two. Both groups of first support shafts 15 are half-missing shaft structures. The first support shafts 15 are provided with first shaft seats 16 supporting their guides along their axial directions, and the two groups of first support shafts 15 are staggered along their axial directions with arm 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 structures 12, the thrust is transmitted to the first support shafts 15 connected thereto through the arm frames 14, so that the first support shafts 15 slide 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, so as to perform self-friction cleaning and dust removal.

[0031] Further, on the other end of the sword grid plate 6, second support shafts 35 are provided in pairs of two. Both sets of second support shafts 35 are semi-missing shaft structures. Along the axial direction of the second support shafts 35, second shaft seats 18 for guiding and supporting them are provided. At one end of one set of second support shafts 35, there is a propulsion sleeve 36 that applies pressure to the first return spring 37, and at one end of the other set of second support shafts 35, there is a braking handle 38 that applies pressure to the second return spring 39. When the sword grid plate 6 undergoes staggered displacement relative to the other set, its thrust drives the second support shafts 35 to slide relative to the other set, and then the propulsion sleeve 36 applies pressure to the first return spring 37 or the braking handle 38 applies pressure to the second return spring 39 alone, causing the sword grid plate 6 to reset after the staggered displacement and maintaining the relative staggered displacement state of the sword grid plate 6.

[0032] In addition, the sliding contact surfaces between the push table 123 and the bearing table 133 are both inclined plane structures. The contact displacement track of the push table 123 along the two bearing tables 133 is located within the sliding track of the sliding buckle 31 along the step chute 29. By setting the push table 123 and the bearing table 133 as inclined plane structures, the two are kept in a staggered pushing state, and by setting the contact displacement track of the push table 123 along the bearing table 133 within the sliding track of the sliding buckle 31 along the step chute 29, when the sliding buckle 31 slides along the step chute 29, at this time the friction grid plate 7 steps up the steel plate on the sword grid plate 6, and the steel plate remains separated from the sword grid plate 6, so that when the push table 123 and the bearing table 133 are forced to push the sword grid plate 6 to undergo staggered displacement, the displacement of the sword teeth will not scrape and damage the steel plate.

[0033] It should be noted that a relief chute 33 for guiding the displacement of the guide sleeve 26 is provided above the drive housing 8. The top end of the guide sleeve 26 is provided with a cover 34 for closing the relief chute 33. Through the setting of the relief chute 33, a displacement space is provided for the guide sleeve 26 to push the top support rod 25 to translate, enabling the top support rod 25 to have both lifting and horizontal displacement states. And through the setting of the cover 34, the relief chute 33 is closed to prevent impurities such as cutting ash from falling into the drive housing 8 through the relief chute 33 and affecting its transmission efficiency.

[0034] During use (operation), the kitchenware steel plate to be cut is placed on the cutting platform composed of the sword grid plates 6, and then based on the three-way braking drive structure formed by the X-axis guide rail 2, Y-axis guide rail 3, and Z-axis guide rail 4, the laser cutting gun 5 is driven to undergo three-way displacement to perform the cutting and blanking work on the kitchenware steel plate.

[0035] After the cutting and blanking are completed, driven by the drive motor 9, the first power shaft 10 is pushed to rotate, generating a thrust. While the first power shaft 10 rotates, the cam 23 is driven to rotate. By using the eccentric rotation of the cam 23, a jacking thrust is applied to the friction grating plate 7, which relatively rubs against both sides of the sword grating plate 6, and a friction cleaning process is carried out on the cutting ash on both sides of the sword grating plate 6. At the same time, the first power shaft 10 synchronously drives the stepping shaft sleeve 27 to rotate, so that the sliding buckle 31 slides along the grooves of the first stop chute 28, the stepping chute 29, and the second stop chute 30 on the stepping shaft sleeve 27, converting the rotational force of the first power shaft 10 into a horizontal thrust and transmitting it to the second power shaft 22, applying a horizontal thrust to the friction grating plate 7. While the friction grating plate 7 is jacked and displaced, it also has a horizontal displacement, forming a stepping push state, and stepping forward and discharging the steel plate on the sword grating plate 6.

[0036] And while stepping forward and discharging the steel plate, the second power shaft 22 drives the reciprocating support arm 11 to displace synchronously. While the friction grating plate 7 steps up and lifts the steel plate, the propulsion seat structure 12 is pushed to alternately bear forces with the two groups of bearing seat structures 13 in turn, and the braking thrust is transmitted to the adjacent two groups of sword grating plates 6 through the arm force frame 14 in turn, causing one group of sword grating plates 6 to alternately displace relative to the other group of sword grating plates 6, performing self-friction cleaning and ash removal. Then, in this state, while circularly friction cleaning and removing the cutting ash on the sword grating plate 6, the steel plate on the sword grating plate 6 is also stepped forward and discharged, without the need for manual labor to climb onto the cutting table to pick up and discharge the materials one by one.

[0037] On the other hand, the present invention also provides a blanking method for kitchenware steel plates based on laser cutting, including the following steps: Step 1: After the laser cutting and blanking of the steel plate on the sword grating plate 6 are completed, the friction grating plate 7 steps and displaces, relatively rubbing and displacing with both sides of the sword grating plate 6, performing friction cleaning on the cutting ash on both sides of the sword grating plate 6, and after the friction cleaning, maintaining the stepped displacement state to push the steel plate on the sword grating plate 6 to displace and discharge. Step 2: While the friction grating plate 7 steps up and lifts the steel plate on the sword grating plate 6, the adjacent two groups of sword grating plates 6 alternately rub against the other group in turn, performing friction cleaning on the cutting ash in the tooth gaps of the sword grating plate 6.
