Description

Technical Field

[0001] This invention relates to the field of laser processing technology, specifically to a laser processing and forming equipment for superhard cutting tools. Background Technology

[0002] Superhard cutting tools are typically made of superhard materials such as diamond and cubic boron nitride. They have advantages such as high hardness, good wear resistance and long service life, and are widely used in precision machining, aerospace, automobile manufacturing and hard material processing.

[0003] In the manufacturing process of superhard cutting tools, laser processing equipment is typically used to cut, groove, or shape the tool blank. Due to the high hardness and brittleness of superhard materials, traditional mechanical cutting methods can easily generate large cutting forces and processing stresses, leading to problems such as chipping and damage to the tool blank. Therefore, laser processing has gradually become an important processing method for the precision forming of superhard cutting tools.

[0004] Existing laser processing equipment typically requires a fixture to fix the tool blank when machining superhard tool blanks to ensure that the laser head processes along a predetermined trajectory. However, existing fixture structures still have the following shortcomings: First, existing fixtures typically use mechanical clamping to fix the tool blank. During laser cutting, as the cutting area gradually separates, the local structural stability of the tool blank decreases, making it susceptible to factors such as thermal stress generated by laser processing and impact from auxiliary airflow. This can cause the processing area to warp, shift, or vibrate, thereby affecting the accuracy of the laser cutting path and reducing processing precision.

[0005] Secondly, to remove slag, dust, and other impurities generated during laser processing, existing laser processing equipment typically incorporates auxiliary air jet structures to blow away residue from the processing area using airflow. However, when the airflow acts on the tool blank, it can easily push the incompletely separated tool area, causing the tool blank to move and further affecting processing stability. Some existing equipment uses vacuum adsorption to assist in fixing the tool blank, achieving clamping by generating negative pressure through adsorption holes. However, in actual processing, since the adsorption holes usually face directly towards the workpiece, debris, dust, and molten impurities generated during processing can easily enter the adsorption holes, causing blockage of the adsorption channels, leading to a decrease in adsorption force or even failure, affecting clamping reliability. Summary of the Invention

[0006] This invention provides a laser processing and forming device for superhard cutting tools, which offers advantages such as easier maintenance and higher reliability. It addresses the problem mentioned in the background section where some existing devices use vacuum adsorption to assist in fixing the tool blank, achieving clamping through negative pressure generated by the adsorption holes. However, in actual processing, since the adsorption holes usually face directly towards the workpiece, debris, dust, and molten impurities generated during processing easily enter the adsorption holes, causing blockage of the adsorption channels, leading to decreased adsorption force or even failure, thus affecting clamping reliability.

[0009] As an optional solution of the laser processing and forming equipment for a superhard cutting tool according to the present invention, the unblocking mechanism includes a second base, and a second unblocking needle is provided on the second base. The position and number of the second unblocking needle correspond one-to-one with the adsorption head, and one end of the second unblocking needle extends into the adsorption head. The second base is elastically connected to the clamping seat by a second rebound spring, and the second base is provided with a second transmission rod, which is located in the second groove.

[0010] As an optional solution for the laser processing and forming equipment for a superhard cutting tool described in this invention, the laser head is provided with an air jet seat, the air jet seat is ring-shaped, and the air jet seat has a plurality of air jet nozzles.

[0012] As an optional solution for the laser processing and forming equipment for a superhard cutting tool according to the present invention, wherein: a cavity is provided at the support rod, one end of the cavity is connected to the main channel, and a piston is provided in the cavity, and the piston is elastically connected to the support rod through a second spring; an air bladder is provided at one end of the cavity, and the air bladder is connected to the inflatable sealing ring through a pipe.

[0013] As an optional solution of the laser processing and forming equipment for a superhard cutting tool according to the present invention, wherein: the clamping seat is provided with a limiting mechanism for limiting the clamping plate, the limiting mechanism includes a limiting protrusion and a limiting claw, the limiting protrusion is fixedly connected to the clamping seat, and the limiting claw is fixedly connected to the clamping plate through a rotating shaft.

[0014] As an optional solution for the laser processing and forming equipment for a superhard cutting tool according to the present invention, the connecting seat is provided with a workpiece, the workpiece is located in the first groove, and the workpiece is provided with a positioning groove in the middle, and the second groove is provided with a positioning rod that matches the positioning groove in the middle.

[0015] As an optional solution for the laser processing and forming equipment for a superhard cutting tool described in this invention, the bottom of the clamping seat is provided with a support foot, and the support foot is detachably connected to the frame by screws.

[0016] The present invention has the following beneficial effects: 1. The laser processing and forming equipment for superhard cutting tools, wherein a clamping mechanism is provided on the frame and a first groove and a second groove are provided on the clamping seat. The first groove is used to accommodate and position the disc-shaped workpiece, and the clamping plates provided on both sides of the first groove are used to clamp the workpiece, so that the workpiece can maintain a stable state during the laser processing.

[0017] Compared to the traditional method that relies solely on mechanical clamping, this application uses a combination of mechanical clamping and negative pressure adsorption, which can simultaneously restrict the horizontal movement and vertical tilting of the workpiece, thereby improving the workpiece's resistance to disturbance during the laser cutting process.

[0018] Especially when laser cutting forms multiple tool blank areas, even if the workpiece's local structure separates, the adsorption component can still maintain the positional stability of each processing area, reducing processing deviations caused by workpiece movement.

[0019] 2. The laser processing and forming equipment for a superhard cutting tool, wherein an air jet seat is provided at the laser head and multiple air jet nozzles are provided on the air jet seat to generate auxiliary airflow.

[0020] This structure can promptly remove impurities such as slag and dust generated during laser processing, improve the cleanliness of the processing area, and prevent slag adhesion from affecting the laser processing effect.

[0021] Meanwhile, since the adsorption components in the clamping mechanism can adsorb the workpiece, they can counteract the pushing effect of the jet airflow on the workpiece, preventing the workpiece from tilting, shifting, or vibrating due to the airflow impact, thus improving the accuracy of laser processing trajectory control.

[0022] 3. The laser processing and forming equipment for superhard cutting tools, in this application, by setting an adsorption component, including a support rod, a main channel and multiple adsorption heads, enables multiple adsorption heads to simultaneously adsorb different areas of the workpiece.

[0023] Compared to traditional single-point adsorption structures, this application uses multiple adsorption heads to form distributed adsorption, improving the uniformity of adsorption force distribution and making the workpiece more stable under force. Simultaneously, this application includes a clearing mechanism, consisting of a first base, a first clearing needle, and a first return spring forming an automatic clearing structure. When the workpiece is installed on the clamping seat, the workpiece can push the first transmission rod, causing the first base to move the first clearing needle, thereby retracting the first clearing needle from the adsorption head and allowing the adsorption head to function normally. After the workpiece is processed and removed, the first base automatically resets under the action of the first rebound spring, allowing the first unblocking needle to re-enter the adsorption head to clean the adsorption channel and seal the adsorption hole.

[0024] With the above structure, the adsorption channel can be automatically maintained without additional manual cleaning, thus improving the long-term operational stability of the equipment. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1 to 6 A laser processing and forming equipment for superhard cutting tools includes a frame 1, on which a cutting mechanism and a clamping mechanism are provided. The cutting mechanism includes an electric slide table 2, on which a support 3 is provided at the moving end of the electric slide table 2. A connecting seat 4 is provided at one end of the support 3, and a laser head 5 is provided on the lower side of the connecting seat 4. A first electric push rod 6 is provided on the support 3 for pushing the connecting seat 4 to move horizontally, and a second electric push rod 7 is provided on the connecting seat 4 for pushing the laser head 5 to rise and fall. The clamping mechanism includes a clamping seat 8, and the clamping seat 8 has a first groove 801 and a second groove 802 in the middle. The first groove 801 has clamping plates 9 on both sides, and the clamping plates 9 are elastically connected to the clamping seat 8 through a first spring 10. The second groove 802 has a plurality of adsorption components, and the adsorption components include a support rod 11. One end of the support rod 11 has a plurality of adsorption heads 12, and the support rod 11 has a main flow channel 1101. The adsorption heads 12 have a secondary flow channel 1201 that communicates with the main flow channel 1101. The second groove 802 also has a clearing mechanism for clearing the adsorption components.

[0034] The unblocking mechanism includes a first base 13, on which a first unblocking needle 14 is provided. The position and number of the first unblocking needles 14 correspond one-to-one with the suction head 12. One end of the first unblocking needle 14 extends into the suction head 12. The first base 13 is elastically connected to the clamping seat 8 via the first rebound spring 15, and the first base 13 is provided with a first transmission rod 16, one end of which extends into the first groove 801.

[0035] The workpiece 25 is disc-shaped. It is cut by a cutting mechanism and clamped by a clamping mechanism. The clamping mechanism includes a clamping seat 8, which has a first groove 801 and a second groove 802. The first groove 801 and the second groove 802 are connected to each other and are stepped. Two clamping plates 9 are provided on the top of the clamping seat 8. The clamping plates 9 are symmetrically arranged on both sides of the first groove 801. The first groove 801 is slightly larger than the workpiece 25. In use, the workpiece 25 is first placed in the first groove 801, and then the clamping plates 9 are used to restrict the workpiece 25 within the first groove 801. The disc-shaped workpiece 25 is cut into small quadrangular pieces by a cutting mechanism. Specifically, for easy clamping, the outer contour of the workpiece 25 remains stationary, and for easy positioning, the center of the workpiece 25 also remains stationary. The cutting mechanism cuts the other areas except for these two parts. A jet seat 21 is provided on the laser head 5, and several jet nozzles 22 are provided on the jet seat 21. The jet seat 21 can clean the generated slag and clean the laser head 5. In order to prevent the blade blank from tilting or moving under the action of the jet seat 21, which would interfere with the cutting of other areas or the movement of the laser head 5, this technical solution also provides an adsorption component at the clamping seat 8, which includes a support rod 11 and an adsorption head 12 on the support rod 11. The adsorption head 12 can adsorb the workpiece 25 to prevent the cut blank from tilting or moving under the action of the jet seat 21.

[0036] Although the presence of the suction head 12 can prevent the air jet seat 21 from causing adverse interference to the cut blank, for the convenience of clamping, the suction hole of the suction head 12 is normally perpendicular to the workpiece 25. That is to say, the suction hole of the suction head 12 is directly upward. This makes it easy for the workpiece 25 or impurities generated during cutting to enter the suction head 12, thereby causing the suction head 12 to be blocked. To solve the above problem, this technical solution also sets a clearing mechanism at the clamping seat 8 to clear and block the suction head 12. Specifically, the unblocking mechanism includes a first base 13, which is elastically disposed within the clamping seat 8. A first transmission rod 16 and a first unblocking needle 14 are respectively provided on the first base 13. When the first base 13 moves up and down, the first unblocking needle 14 can clean the suction head 12. The first transmission rod 16 extends into the first groove 801. During the process of placing the workpiece 25 into the first groove 801, the workpiece 25 will abut against the first transmission rod 16, thereby pushing the first base 13 to overcome the resistance of the first return spring 15 and move down. The first unblocking needle 14 moves synchronously with the first base 13. When the workpiece 25 is removed, after the obstruction of the workpiece 25 is removed, the first base 13, the first unblocking needle 14, and the first transmission rod 16 return to their original positions under the push of the first return spring 15. At this time, one end of the first unblocking needle 14 extends to the outside of the suction head 12, which can play a role in blocking the suction head 12.

[0037] This application provides a unclog needle structure that extends to the outside of the adsorption head 12 when the device is not in operation, thereby blocking the adsorption head 12.

[0038] This structure can reduce the possibility of external dust and processing debris entering the adsorption channel, and reduce the problem of blockage caused by long-term exposure of the adsorption components.

[0039] Meanwhile, since the unblocking needle can automatically change with the clamping state of the workpiece 25, the automatic switching between the open and closed states of the adsorption head 12 can be realized, thereby improving the automation level of the equipment.

[0040] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 6 The unblocking mechanism includes a second base 17, on which a second unblocking needle 18 is provided. The position and number of the second unblocking needles 18 correspond one-to-one with the suction head 12. One end of the second unblocking needle 18 extends into the suction head 12. The second base 17 is elastically connected to the clamping seat 8 via the second rebound spring 19, and the second base 17 is provided with a second transmission rod 20, which is located in the second groove 802.

[0041] The laser head 5 is provided with a jet seat 21, which is ring-shaped and has several jet nozzles 22.

[0042] The secondary flow channel 1201 is L-shaped, and the suction head 12 has an opening 1202 for the unblocking mechanism to enter and exit, and an air-filled sealing ring 1203 is provided at the opening 1202.

[0043] A cavity 1102 is provided at the support rod 11. One end of the cavity 1102 is connected to the main channel 1101. A piston 1103 is provided inside the cavity 1102. The piston 1103 is elastically connected to the support rod 11 through a second spring 1104. An airbag 28 is provided at one end of the cavity 1102. The airbag 28 is connected to the inflatable sealing ring 1203 through a pipe.

[0044] This embodiment discloses another technical solution for the unblocking mechanism. The unblocking mechanism includes a second base 17, which is elastically disposed in the clamping seat 8. A second transmission rod 20 and a second unblocking needle 18 are respectively provided on the second base 17. The second unblocking needle 18 is located in the second groove 802. One end of the second transmission rod 20 extends into the first groove 801. During the process of placing the workpiece 25 into the first groove 801, the workpiece 25 will abut against the second transmission rod 20, thereby pushing the second base 17 to overcome the resistance of the second rebound spring 19 and move downward. The second unblocking needle 18 moves synchronously with the second base 17. When the workpiece 25 is removed, after the obstruction of the workpiece 25 is removed, the second base 17, the second unblocking needle 18, and the second transmission rod 20 return to their original positions under the push of the second rebound spring 19. At this time, one end of the second unblocking needle 18 extends to the outside of the suction head 12, which can play a role in blocking the suction head 12.

[0045] To improve the adsorption effect, an inflatable sealing ring 1203 is provided at the opening 1202. Correspondingly, a cavity 1102 is provided at the support rod 11. One end of the cavity 1102 is connected to the main channel 1101. When air is drawn in, the main channel 1101 is in a negative pressure state, and the airbag 28 is annular. A through hole for airflow is provided in the middle of the airbag 28. Since the cavity 1102 is connected to the main channel 1101, the cavity 1102 will also become a negative pressure state. At this time, the piston 1103 overcomes the resistance of the second spring 1104 and moves towards the airbag 28, squeezing the airbag 28. The gas in the airbag 28 enters the inflatable sealing ring 1203, and the inflatable sealing ring 1203 inflates and expands, tightly fitting with the second unblocking needle 18 or the first unblocking needle 14, effectively reducing the risk of gas leakage.

[0046] After the workpiece 25 is processed, the air source connected to the support rod 11 stops working. At this time, the piston 1103 returns to its original position under the action of the second spring 1104, and the airbag 28 and the inflatable sealing ring 1203 also return to their original state. At this time, the second unblocking needle 18 or the first unblocking needle 14 will not rub excessively against the inflatable sealing ring 1203 during the movement, which can effectively improve the service life of the inflatable sealing ring 1203.

[0047] This application includes a cavity 1102, a piston 1103, an airbag 28, and an inflatable sealing ring 1203. When the adsorption component is working, since the main channel 1101 is under negative pressure, the cavity 1102 connected to the main channel 1101 is also under negative pressure, causing the piston 1103 to move and squeeze the airbag 28, so that the gas inside the airbag 28 enters the inflation sealing ring 1203.

[0048] After expansion, the 1203 inflatable sealing ring can fit tightly with the unblocking mechanism, improving the sealing performance of the adsorption channel, reducing gas leakage, and enhancing the negative pressure adsorption effect.

[0049] Meanwhile, after the equipment stops working, the piston 1103 can automatically reset under the action of the second spring 1104, so that the airbag 28 and the inflatable sealing ring 1203 return to their original state, avoiding excessive friction between the unblocking mechanism and the inflatable sealing ring 1203 during the movement of the unblocking mechanism, and improving the service life of the sealing structure.

[0050] Example 3 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 6 The clamping seat 8 is provided with a limiting mechanism for limiting the clamping plate 9. The limiting mechanism includes a limiting protrusion 23 and a limiting claw 24. The limiting protrusion 23 is fixedly connected to the clamping seat 8, and the limiting claw 24 is fixedly connected to the clamping plate 9 through a rotating shaft.

[0051] The connecting seat 4 is provided with a workpiece 25, which is located in the first groove 801. The workpiece 25 is provided with a positioning groove 26 in the middle, and the second groove 802 is provided with a positioning rod 27 that fits into the positioning groove 26 in the middle.

[0052] The bottom of the clamping base 8 is provided with a support foot 803, and the support foot 803 is detachably connected to the frame 1 by screws.

[0053] Since the position of the clamping plate 9 needs to be adjusted during the process of fixing the workpiece 25, in order to make the adjustment of the clamping plate 9 more convenient, this technical solution provides a limiting mechanism for limiting the clamping plate 9 on the clamping seat 8. It includes a limiting protrusion 23 and a limiting claw 24. The limiting protrusion 23 is fixed on the clamping seat 8, and the limiting claw 24 is rotatably set on the clamping plate 9. When it is necessary to limit the clamping plate 9, simply push the clamping plate 9 to move closer to the limiting protrusion 23, then rotate the limiting claw 24 so that its movement trajectory coincides with the limiting protrusion 23. Then release the clamping plate 9. Under the action of the clamping plate 9, the limiting protrusion 23 and the limiting claw 24 abut against each other. At this time, the clamping plate 9 will stop moving under the combined action of the limiting protrusion 23 and the limiting claw 24. Subsequently, place the workpiece 25 into the first groove 801 and hold it down with one hand. Then, use the other hand to adjust the limiting claw 24 so that its movement trajectory is offset from the limiting protrusion 23. In this way, the clamping plate 9 can move freely. Following the above steps, loosen the clamping plates 9 on both sides of the first groove 801. The clamping plates 9 return to their original position under the push of the first spring 10. In this way, the workpiece 25 can be restricted in the first groove 801 by the clamping plates 9, which is convenient to operate.

[0054] The clamping seat 8 is detachably mounted on the frame 1 by screws. In order to facilitate the cutting mechanism to cut the workpiece 25, this technical solution also pre-sets a positioning groove 26 on the workpiece 25. Correspondingly, a positioning rod 27 with a size that matches the positioning groove 26 is also set in the second groove 802. One end of the positioning rod 27 extends into the first groove 801. During the clamping process of the workpiece 25, the positioning groove 26 on the workpiece 25 is aligned with the positioning rod 27 in the second groove 802. Then the workpiece 25 is placed into the first groove 801. Under the joint action of the positioning rod 27 and the positioning groove 26, the workpiece 25 is centered.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
