Description

Technical Field

[0001] This application relates to the field of laser hardening technology, and in particular to a laser hardening device and hardening process for a clamp blade. Background Technology

[0002] The blades of pliers are used for cutting, so they need to have high strength and hardness. Therefore, the blades need to be hardened.

[0003] The traditional method for hardening the blades of pliers involves placing the pliers in a heating furnace for heating, followed by water or oil spraying for cooling. However, this process requires a long time for the electric heating furnace to heat the blades, resulting in low hardening efficiency. Summary of the Invention

[0004] To address the problem of long heating time and low quenching efficiency of clamp blades, this application provides a clamp blade laser quenching device and quenching process.

[0005] On the one hand, the laser hardening device for clamp blades provided in this application adopts the following technical solution:

[0006] A laser hardening device for pliers includes a worktable, a movable frame on the worktable, a laser hardening head on the movable frame, a feeding unit on the worktable for transporting pliers to a hardening station on the worktable, the movable frame for adjusting the laser beam of the laser hardening head to move along the pliers blade, a loading unit on the worktable for loading the pliers onto the feeding unit, and a unloading unit on the worktable for unloading the hardened pliers from the feeding unit.

[0007] By adopting the above technical solution, when quenching the blades of the pliers, the loading unit adds the pliers to the feeding unit, which continuously transports the pliers to the quenching station. Then, the moving frame moves the laser quenching head toward the blades of the pliers, and the high-temperature laser emitted by the laser quenching head moves on the blades of the pliers to quench them. After quenching, the pliers are collected by the unloading unit, thus realizing the quenching of the pliers' blades. Compared with the furnace quenching method, this solution can shorten the heating time of the blades and eliminates the need for a cooling medium, thereby improving the quenching efficiency of the pliers' blades.

[0008] In one specific implementation scheme, the feeding unit includes a conveyor belt mechanism and a first motor. The conveyor belt mechanism is rotatably mounted on the workbench and is used to place the tool clamps. The first motor is mounted on the workbench and connected to the conveyor belt mechanism through a connector. The first motor can drive the conveyor belt mechanism to rotate and drive the tool clamps to move one by one to the quenching station.

[0009] By adopting the above technical solution, when feeding the tool pliers, the first motor drives the conveyor belt mechanism to rotate through the connecting parts, and the conveyor belt mechanism drives the tool pliers to move towards the quenching station, thereby realizing the continuous feeding of the tool pliers.

[0010] In one specific implementation scheme, the unloading unit includes a linear drive mechanism, a baffle, and a control board. The worktable has an unloading port at the quenching station. The linear drive mechanism is mounted on the worktable. The control board is fixedly mounted on the output shaft of the linear drive mechanism. The control board is used to place the tool clamp. The baffle is mounted on the worktable and is used to prevent the tool clamp from moving, so that the tool clamp is located on the control board. There is space between the baffle and the conveyor belt mechanism for the tool clamp to fall. The linear drive mechanism can drive the control board to move, so that the tool clamp is detached from the control board and falls into the unloading port.

[0011] By adopting the above technical solution, when the pliers blade is quenched, the pliers slide onto the control plate and, under the obstruction of the baffle, the pliers are positioned at the quenching station for quenching. After quenching, the linear drive mechanism drives the control plate to slide, and under the obstruction of the baffle, the control plate disengages from the pliers, causing the pliers to lose support and fall into the discharge port under the force of gravity, thus realizing the discharge of the quenched pliers. After the discharge is completed, the first linear motor drives the control plate to move between the baffle and the conveyor belt mechanism, and then the pliers slide onto the control plate for quenching. The above process is repeated continuously to realize the discharge operation for each quenched pliers, improving the convenience of discharging the pliers.

[0012] In one specific implementation, the workbench is provided with a rotating mechanism, and the output shaft of the rotating mechanism is provided with a striking rod, which can push the tool clamp that is in contact with the baffle into the discharge port.

[0013] By adopting the above technical solution, when the baffle separates from the quenched tool clamp, the rotating mechanism drives the striking rod to strike the quenched tool clamp and enter the discharge port, thereby effectively preventing the tool clamp from getting stuck and improving the reliability of the quenched tool clamp discharge.

[0014] In one specific implementation scheme, the workbench is provided with a first mounting plate, the first mounting plate has a first oblong hole, the first mounting plate is provided with a first bolt, the first bolt passes through the first oblong hole and is connected and fixed to the workbench, the baffle is fixedly provided on the first mounting plate, the first mounting plate is provided with a second mounting plate, the second mounting plate has a second oblong hole and a second bolt, the second bolt passes through the second oblong hole and is connected and fixed to the first mounting plate, the linear drive mechanism is fixedly provided on the second mounting plate, and the baffle is fixedly provided on the first mounting plate.

[0015] By adopting the above technical solution, when quenching the blades of different specifications of tool pliers, the position of the first mounting plate can be adjusted by turning the first bolt, and the distance between the baffle and the conveyor belt mechanism can be adjusted at the same time to accommodate the unloading of tool pliers of different specifications; by turning the second bolt, the distance between the control plate and the conveyor belt mechanism can be adjusted, so that the tool pliers can slide onto the control plate, thereby improving the processing range of the quenching device.

[0016] In one specific implementation, a sensor is provided on the workbench, the sensor being used to detect whether the tool pliers are present on the control board.

[0017] By adopting the above technical solution, the presence of a tool pliers on the control board can be detected by a sensor, effectively preventing the laser quenching head from running idle and improving the accuracy of the quenching process.

[0018] In one specific implementation scheme, the feeding unit includes a feeding plate and a spiral telescopic rod. The tool pliers can be arranged and placed inside the feeding plate. One end of the feeding plate is rotatably connected to the workbench and located on the conveyor belt mechanism, and the other end is rotatably connected to the spiral telescopic rod. The spiral telescopic rod is rotatably connected to the workbench and can support the feeding plate to tilt, so that the tool pliers slide onto the conveyor belt mechanism.

[0019] By adopting the above technical solution, when feeding materials onto the conveyor belt mechanism, the feeding plate is first tilted by rotating the bolt telescopic rod. Then, a group of tool pliers is placed on the feeding plate. Under the action of its own gravity, the tool pliers slide up the feeding plate onto the conveyor belt mechanism, thereby realizing the continuous feeding of tool pliers onto the conveyor belt mechanism.

[0020] In one specific implementation, the workbench is provided with a circulating moving mechanism, which has several placement boxes. Each placement box is used to hold a set of the tool pliers. The circulating moving mechanism can drive the placement box to align with the highest end of the loading plate. One end of the placement box near the loading plate is hinged to the circulating moving mechanism via a hinge shaft. The circulating moving mechanism is provided with a hydraulic cylinder. The piston rod end of the hydraulic cylinder abuts against the placement box and pushes one end of the placement box to lift, so that the tool pliers slide into the loading plate.

[0021] By adopting the above technical solution, in the process of placing a group of pliers into the loading plate, the group of pliers is first placed into multiple placement boxes. Then, a cyclic moving mechanism moves the placement boxes one by one to the position of the loading plate. When the placement box moves to the position of the loading plate, the hydraulic cylinder pushes the placement box to rotate around the hinge axis, so that the placement box is aligned with the loading plate, and the pliers in the placement box can slide into the loading plate. Then the hydraulic cylinder retracts, and the placement box rotates to the cyclic moving mechanism. Then the cyclic moving mechanism rotates the next placement box to the loading plate, and the above process is repeated continuously, thereby realizing continuous automated feeding of pliers and improving the convenience of feeding pliers.

[0022] In one specific implementation, a reciprocating screw is rotatably mounted on the placement box, the reciprocating screw being arranged along the sliding direction of the tool clamp. A control block is slidably mounted on the placement box, the reciprocating screw passing through the control block and being threadedly connected. A receiving block is slidably mounted on the control block, the receiving block being used to support the tool clamp sliding out of the placement box. The receiving block is provided with a guide surface, the guide surface pressing against the tool clamp in the loading box, causing the receiving block to release its support for the tool clamp. A second motor is mounted on the placement box, the output shaft of the second motor being coaxially and fixedly connected to the reciprocating screw.

[0023] By adopting the above technical solution, when the blocking part releases its obstruction of the tool clamps, the tool clamps slide onto the receiving block. Then, the second motor drives the reciprocating screw to rotate, and the reciprocating screw drives the control block to slide. The control block, through the receiving block, drives the tool clamps to slide down into the support cylinder, thereby effectively preventing the tool clamps from becoming disordered during the descent, ensuring the neatness of the group of tool clamps and improving the accuracy of the tool clamp position. When the receiving block slides down to the original tool clamps on the support cylinder, the guide surface presses the tool clamps, causing the receiving block to move out between the two groups of tool clamps, allowing the two groups of tool clamps to be stacked together, facilitating the falling of newly added tool clamps onto the conveyor belt mechanism.

[0024] On the other hand, the laser hardening process for clamp blades provided in this application adopts the following technical solution:

[0025] A laser hardening process for a clamp-shaped blade, using the aforementioned laser hardening apparatus for clamp-shaped blades, includes the following steps:

[0026] S1. Loading: The tool clamp is added to the feeding unit through the loading unit, and the feeding unit transports the tool clamp to the quenching station.

[0027] S2. Quenching: The moving frame aligns the laser quenching head with the cutting edge of the tool pliers and moves the laser of the laser quenching head on the cutting edge to quench it.

[0028] S3, Blanking: The quenched tool pliers are collected and blanked through the blanking unit.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. When quenching the blades of a pair of pliers, the loading unit adds the pliers to the feeding unit. The feeding unit continuously transports the pliers to the quenching station. Then, the moving frame moves the laser quenching head toward the blades of the pliers and moves the high-temperature laser emitted by the laser quenching head on the blades of the pliers to quench them. The quenched pliers are collected by the unloading unit, thus achieving the quenching of the blades of the pliers. Compared with the furnace quenching method, this solution can shorten the heating time of the blades and eliminates the need for a cooling medium, thereby improving the quenching efficiency of the pliers blades.

[0031] 2. When quenching the blades of pliers of different specifications, the position of the first mounting plate is adjusted by turning the first bolt, and the distance between the baffle and the conveyor belt mechanism is adjusted at the same time. By turning the second bolt, the distance between the control plate and the conveyor belt mechanism can be adjusted, so that the pliers can slide onto the control plate to accommodate the unloading of pliers of different specifications, thereby improving the processing range of the quenching device.

[0043] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0044] On the one hand, this application discloses a laser hardening device for clamp blades.

[0045] Example 1

[0046] Reference Figure 1 A laser hardening device for a clamp blade includes a worktable 2, on which a movable frame 3, a feeding unit 4, a loading unit 5, a unloading unit 6, and a laser hardening head 7 are provided. There are two laser hardening heads 7, both of which are mounted on the movable frame 3. The movable frame 3 can adjust the laser of the laser hardening head 7 to move along the clamp blade of the clamp tool 1. The worktable 2 is provided with a hardening station 21, where the laser hardening head 7 hardens the clamp blade of the clamp tool 1. The feeding unit 4 can transport the clamp tool 1 to the hardening station 21 on the worktable 2. The loading unit 5 is used to load the clamp tool 1 onto the feeding unit 4. The unloading unit 6 is used to unload the hardened clamp tool 1 from the feeding unit 4. The bottom of the worktable 2 is provided with a conveying mechanism 22, which is used to receive the unloaded clamp tool 1. The conveying mechanism 22 adopts a conveyor belt structure to output the unloaded clamp tool 1.

[0047] When quenching the blade of the pliers 1, the loading unit 5 adds the pliers 1 to the feeding unit 4. The feeding unit 4 continuously transports the pliers 1 to the quenching station 21. Then, the moving frame 3 drives the laser quenching head 7 toward the blade of the pliers 1, and drives the high-temperature laser emitted by the laser quenching head 7 to move on the blade of the pliers 1 to quench it. After quenching, the pliers 1 falls onto the conveying mechanism 22 through the unloading unit 6. Then, the conveying mechanism 22 outputs and collects the pliers 1, thereby realizing the quenching of the blade of the pliers 1. Compared with the furnace quenching method, this solution uses laser heating quenching, which can shorten the heating time of the blade and eliminates the need for a cooling medium, thereby improving the quenching efficiency of the blade of the pliers 1.

[0048] Reference Figure 1 In this embodiment, the movable frame 3 includes an X-axis moving mechanism 31, a Y-axis moving mechanism 32, a Z-axis moving mechanism 33, and a rotating mechanism 34. Each of the X-axis moving mechanism 31, Y-axis moving mechanism 32, and Z-axis moving mechanism 33 consists of a support frame, a servo motor, a screw, and a slider. The slider is slidably mounted on the support frame, the servo motor is fixedly mounted on one end of the support frame, and the screw is coaxially fixedly mounted on the output shaft of the servo motor. The screw passes through the slider and is threadedly connected to the slider.

[0049] Reference Figure 1 , Figure 2The rotating mechanism 34 includes a rotating disk 341, which corresponds one-to-one with the laser quenching head 7. The laser quenching head 7 is fixedly mounted on the rotating disk 341 by bolts. The slider of the Z-axis moving mechanism 33 is provided with a support plate 342. Each rotating disk 341 is rotatably connected to the support plate 342 through a rotating shaft. The rotating disk 341 is provided with an arc-shaped waist hole 343. The rotating disk 341 is fixedly connected to the support plate 342 by bolts. The bolts pass through the arc-shaped waist hole 343 and are screwed into the support plate 342. By loosening the bolts and rotating the rotating disk 341, the bolts slide in the arc-shaped waist hole 343. Then, the bolts are tightened to adjust and fix the orientation of the laser quenching head 7.

[0050] Reference Figure 3 In this embodiment, the feeding unit 4 includes a conveyor belt mechanism 41 and a first motor 42. The conveyor belt mechanism 41 includes a conveyor belt 411 and two rotating rollers 412. A support plate 23 is provided on the workbench 2. The two rotating rollers 412 are rotatably mounted on the support plate 23. The two rotating rollers 412 are arranged in parallel and spaced apart. The two rotating rollers 412 are arranged in the same horizontal plane. The conveyor belt 411 is sleeved on the two rotating rollers 412 and taut. Pliers 1 are placed one by one on the conveyor belt 411. The pliers 1 have their blades facing upward and are located outside the conveyor belt 411. The first motor 42 is fixedly mounted on the workbench 2 and is connected to one of the rotating rollers 412 through a connector 43. In this embodiment, the connector 43 is a synchronous belt mechanism. In other embodiments, it can also be a chain drive, gear drive mechanism, etc. The front end is the direction in which the conveyor belt 411 slides. The front end of the conveyor belt 411 is located at the quenching station 21.

[0051] Reference Figure 3 , Figure 4 In this embodiment, the feeding unit 5 includes a feeding plate 51 and a spiral telescopic rod 52. The feeding plate 51 is a "C" shaped plate. One end of the feeding plate 51 is hinged to the support plate 23 and is located above the conveyor belt 411. The other end is hinged to the spiral telescopic rod 52. The end of the spiral telescopic rod 52 away from the feeding plate 51 is hinged to the workbench 2. By rotating the handle in the middle of the spiral telescopic rod 52, the extension and retraction of both ends can be achieved. The spiral telescopic rod 52 can support the tilt of the feeding plate 51. The end of the feeding plate 51 that is hinged to the spiral telescopic rod 52 is higher than the other end. The tilt angle of the feeding plate 51 can be adjusted by the extension and retraction of the spiral telescopic rod 52, so that the tilt angle of the feeding plate 51 is greater than the friction angle of the tool pliers 1, and the tool pliers 1 can slide down along the feeding plate 51.

[0052] Reference Figure 4A limiting plate 53 is provided inside the feeding plate 51, and the limiting plate 53 is set along the sliding direction of the tool pliers 1. Two limiting sleeves 54 are fixedly provided on the side wall of the feeding plate 51. Each limiting sleeve 54 is provided with a limiting screw 55. The limiting screw 55 passes through the limiting sleeve 54 and the side wall of the feeding plate 51, and is threadedly connected to the limiting sleeve 54. A rotating support cylinder 56 is fixedly provided on the limiting plate 53. The rotating support cylinder 56 corresponds one-to-one with the limiting screw 55. After passing through the feeding plate 51, the limiting screw 55 is inserted into the rotating support cylinder 56 and is rotatably connected to the rotating support cylinder 56. By rotating the limiting screw 55, the sliding of the tool pliers 1 in the feeding plate 51 can be limited, thereby improving the accuracy of the tool pliers 1 sliding onto the conveyor belt 411.

[0053] Reference Figure 3 , Figure 5 In this embodiment, the unloading unit 6 includes a linear drive mechanism 61, a baffle 62, and a control board 63. The linear drive mechanism 61 in this embodiment is a linear cylinder; in other embodiments, it can be a hydraulic cylinder, a linear motor, etc. Two support plates 23 are provided with first mounting plates 641. Each first mounting plate 641 has multiple first oblong holes 642 at positions corresponding to the two support plates 23. Multiple first bolts 643 are provided on the first mounting plate 641, with each first bolt 643 corresponding to a first oblong hole 642. The first bolts 643 pass through the first oblong holes 642 and are threadedly connected to the support plates 23. A second mounting plate 644 is provided on the mounting plate 641. A groove 645 is provided on the first mounting plate 641, and the second mounting plate 644 is disposed within the groove 645. The second mounting plate 644 has multiple second oblong holes 646. The second mounting plate 644 and the first mounting plate 641 are connected by second bolts 647. Each second bolt 647 corresponds to a second oblong hole 646. The second bolts 647 pass through the second oblong holes 646 and are threadedly connected to the first mounting plate 641. A linear drive mechanism 61 is fixedly mounted on the second mounting plate 644, and the output shaft of the linear drive mechanism 61 faces the front end of the conveyor belt 411. Two sets of first threaded seats 648 are fixedly provided on the support plate 23. Each set of first threaded seats 648 has a first abutting head 649. The first abutting head 649 passes through the first threaded seat 648 and is threadedly connected to the first threaded seat 648. The first abutting head 649 abuts against the side of the first mounting plate 641 away from the conveyor belt 411. The first mounting plate 641 is fixedly provided with a second threaded seat 651 at one end away from the conveyor belt 411. The second threaded seat 651 is provided with a second abutting head 652. The second abutting head 652 passes through the second threaded seat 651 and is threadedly connected to the second threaded seat 651. The second abutting head 652 abuts against the side of the second mounting plate 644 away from the conveyor belt 411.

[0054] Reference Figure 3 , Figure 5A horizontally arranged guide plate 66 is provided on the support plate 23. The guide plate 66 is located at the front end of the conveyor belt 411. The tool pliers 1 on the conveyor belt 411 can slide onto the guide plate 66. The workbench 2 is provided with a discharge port 67, which is located below the guide plate 66 and above the conveying mechanism 22. The baffle 62 is fixedly installed on the first mounting plate 641 and located above the discharge port 67. There is space between the baffle 62 and the guide plate 66 for a tool pliers 1 to fall. The control plate 63 is fixedly installed on the output shaft of the linear drive mechanism 61. The control plate 63 extends through the baffle 62 and between the baffle 62 and the guide plate 66. The tool pliers 1 can slide onto the control plate 63 along the guide plate 66.

[0055] When quenching the blades of the pliers 1, the pliers 1 in a group are first placed in the loading plate 51. Under their own weight, the pliers 1 slide down the loading plate 51 one by one onto the conveyor belt 411. Then, the first motor 42 drives the conveyor belt 411 to rotate. The conveyor belt 411 moves the pliers 1 one by one to the control plate 63, where they come into contact with the baffle 62. Then, the moving frame 3 drives the laser quenching head 7 to slide along the blades of the pliers 1 to quench the blades. After quenching, the linear drive mechanism 61 drives the control plate 63 away from the guide plate 66. At this time, the quenched pliers 1 lose the support of the control plate 63 and fall into the discharge port 67, completing the automated discharge of the quenched pliers 1.

[0056] After a tool clamp 1 is unloaded, the linear drive mechanism 61 drives the control board 63 to quickly slide back between the baffle 62 and the guide plate 66 to support the next tool clamp 1. The above process is repeated continuously to realize the automated unloading of each quenched tool clamp 1, thereby improving the convenience of unloading the tool clamp 1.

[0057] When quenching the blades of different sized pliers 1, the position of the first mounting plate 641 is adjusted by turning the first bolt 643, and the distance between the baffle 62 and the conveyor belt mechanism 41 is adjusted to accommodate the unloading of different sized pliers 1. By turning the second bolt 647, the distance between the control plate 63 and the conveyor belt mechanism 41 can be adjusted, allowing the pliers 1 to slide onto the control plate 63, thereby increasing the processing range of the quenching device. The stability of the linear drive mechanism 61 is improved by the clamping of the first mounting plate 641 by the first clamping head 649 and the clamping of the second mounting plate 644 by the second clamping head 652.

[0058] Reference Figure 3 , Figure 5A rotating mechanism 681 is fixedly provided on the baffle 62. In this embodiment, the rotating mechanism 681 is a rotary cylinder. In other embodiments, it can also be a rotary motor. A striking rod 682 is fixedly provided on the output shaft of the rotating mechanism 681. The striking rod 682 is arranged radially along the output shaft of the rotating mechanism 681. The width of the striking rod 682 is smaller than the width of a single tool pliers 1. The striking rod 682 can push the tool pliers 1 that are in contact with the baffle 62 into the feed port 67.

[0059] When the control panel 63 is disengaged from the tool clamp 1, the conveyor belt 411 continues to rotate, pushing the remaining tool clamps 1 to press the quenched tool clamps 1 onto the baffle 62, preventing the quenched tool clamps 1 from falling off due to their own weight. At this time, the rotating mechanism 681 drives the striking rod 682 to strike the quenched tool clamps 1, knocking the tool clamps 1 into the material drop port 67, thereby improving the stability and smoothness of the tool clamps 1 dropping material.

[0060] Reference Figure 3 , Figure 5 The workbench 2 is equipped with a sensor 69. In this embodiment, the sensor 69 is a laser sensor 69. The sensor 69 is used to detect whether there is a tool pliers 1 on the control board 63, thereby reminding the worker and effectively avoiding the laser quenching head 7 running idle, thus improving the accuracy of quenching processing.

[0061] The implementation principle of Example 1 is as follows: When quenching the blades of the pliers 1, the pliers 1 in a group are first placed in the loading plate 51. Under the action of their own gravity, the pliers 1 slide down the loading plate 51 one by one onto the conveyor belt 411. Then, the first motor 42 drives the conveyor belt 411 to rotate. The conveyor belt 411 moves the pliers 1 one by one to the control plate 63, where they contact the baffle 62. Then, the moving frame 3 drives the laser quenching head 7 to slide along the blades of the pliers 1 to perform the quenching operation. After quenching, the linear drive mechanism 61 drives the control plate 63 away from the guide plate 66. At this time, the quenched pliers 1 lose the support of the control plate 63 and fall into the drop port 67, thereby realizing the quenching of the blades of the pliers 1. Compared with the furnace quenching method, this scheme uses laser heating quenching, which can shorten the heating time of the blades and does not require the use of a cooling medium, thereby improving the quenching efficiency of the blades of the pliers 1.

[0062] Example 2

[0063] Reference Figure 6The difference between this embodiment and embodiment 1 is that the worktable 2 is also provided with a circulating moving mechanism 8. The circulating moving mechanism 8 includes a circulating platform 81, a synchronous belt 82, and pulleys 83. The circulating platform 81 and four lifting rods 84 are connected to the worktable 2. There are two pulleys 83. The two pulleys 83 are embedded in the circulating platform 81. The axes of the two pulleys 83 are perpendicular to the table surface of the circulating platform 81. The synchronous belt 82 is sleeved on the two pulleys 83 and meshes with each pulley 83. The synchronous belt 82 is also embedded in the circulating platform 81. A third motor 85 is fixedly provided on the circulating platform 81. The output shaft of the third motor 85 is coaxially fixedly connected to one of the pulleys 83.

[0064] Reference Figure 7 , Figure 8 Multiple trays 86 are slidably mounted on the circulation table 81. The trays 86 are fixedly connected to the timing belt 82. Each tray 86 is equipped with a placement box 87. The placement box 87 has openings on the top and both sides. Each placement box 87 can hold a set of tool pliers 1. A hinge plate 881 is fixedly mounted on one end of the placement box 87 near the loading plate 51. A hinge shaft 882 is fixedly mounted on the hinge plate 881. The hinge shaft 882 is inserted into the tray 86 and rotated. When the placement box 87 slides to the position of the loading plate 51, the end face of the placement box 87 can fit against the end face of the loading plate 51.

[0065] Reference Figure 7 , Figure 9 The circulation table 81 is equipped with a hydraulic cylinder 89 at a position corresponding to the loading plate 51. The cylinder body of the hydraulic cylinder 89 is embedded in the circulation table 81. When the piston rod of the hydraulic cylinder 89 retracts, the piston rod of the hydraulic cylinder 89 can retract into the circulation table 81. The hydraulic cylinder 89 is tilted towards one side of the loading plate 51. The cylinder body of the hydraulic cylinder 89 is fixedly connected to the worktable 2. The piston rod end of the hydraulic cylinder 89 abuts against the placement box 87 and pushes one end of the placement box 87 to lift, so that the tool pliers 1 slides into the loading plate 51.

[0066] Reference Figure 6 , Figure 10A bracket 91 is fixedly provided on the feeding plate 51. The bracket 91 is positioned above the tool pliers 1 inside the feeding plate 51. A second motor 92 is fixedly provided on the bracket 91. The output shaft of the second motor 92 is positioned upward along the sliding direction of the tool pliers 1. A reciprocating screw 93 is coaxially fixed on the output shaft of the second motor 92. The extension height of the reciprocating screw 93 is higher than the height of the feeding plate 51. A guide rod 94 is fixedly provided on the bracket 91. The extension direction of the guide rod 94 is the same as the direction of the reciprocating screw 93. A control block 95 is provided on the guide rod 94. The guide rod 94 passes through the control block 95 and is slidably connected. The reciprocating screw 93 passes through the control block 95 and is threadedly connected. A receiving block 96 is provided on the control block 95. A slide rod 98 is fixedly provided on the receiving block 96. The slide rod 98 passes through the control block 95 and is slidably connected to the control block 95 along a direction perpendicular to the sliding direction of the tool pliers 1. A guide surface 97 is provided on the receiving block 96. The guide surface 97 is located on the side of the receiving block 96 facing the conveyor belt 411. The guide surface 97 presses the tool pliers 1 in the feeding plate 51, so that the receiving block 96 releases its support for the tool pliers 1.

[0067] The implementation principle of Example 2 is as follows: In the process of placing a group of pliers 1 into the loading plate 51, the group of pliers 1 is first placed into multiple placement boxes 87. Then, the cyclic moving mechanism 8 moves the placement boxes 87 one by one to the position of the loading plate 51. When the placement box 87 moves to the position of the loading plate 51, the hydraulic cylinder 89 pushes the placement box 87 to rotate around the hinge axis 882, so that the placement box 87 is aligned with the loading plate 51, and the pliers 1 in the placement box 87 can slide into the loading plate 51. Then the hydraulic cylinder 89 retracts, and the placement box 87 rotates onto the support plate 86. Then the cyclic moving mechanism rotates the next placement box 87 to the loading plate 51. The above process is repeated continuously to realize the continuous automated loading of the pliers 1, thereby improving the convenience of loading the pliers 1.

[0068] When the placement box 87 rotates, the control block 95 moves the support block to the tool pliers 1 inside the placement box 87. Then, as the placement box 87 flips, the tool pliers 1 inside the placement box 87 overlaps with the receiving block 96. The support of the receiving block 96 and the tool pliers 1 effectively prevents the tool pliers 1 from collapsing, making the tool pliers 1 more neat. Then, the second motor 92 drives the reciprocating screw 93 to rotate, and the reciprocating screw 93 drives the control block 95 to slide. The control block 95, through the receiving block 96, drives the tool pliers 1 to slowly slide down into the loading plate 51, thereby effectively preventing the tool pliers 1 from becoming disordered during the descent and improving the neatness of the group of tool pliers 1. When the receiving block 96 slides down to the original tool pliers 1 on the loading plate 51, the guide surface 97 presses the tool pliers 1, causing the receiving block 96 to move out between the two groups of tool pliers 1, so that the two groups of tool pliers 1 can be stacked together, making it easier for the newly added tool pliers 1 to fall onto the conveyor belt 411.

[0069] On the other hand, this application discloses a laser hardening process for clamp blades.

[0070] A laser hardening process for clamp-shaped blades, using the aforementioned laser hardening apparatus for clamp-shaped blades, includes the following steps:

[0071] S1. Loading: The tool clamp 1 is added to the feeding unit 4 through the loading unit 5, and the feeding unit 4 transports the tool clamp 1 to the quenching station 21.

[0072] S2, Quenching: The moving frame 3 aligns the laser quenching head 7 with the blade of the tool pliers 1, and moves the laser of the laser quenching head 7 on the blade to quench it.

[0073] S3, Blanking: The quenched tool pliers 1 are collected by the blanking unit 6.

[0074] In step S1, the operator places a group of tool pliers 1 into the loading plate 51. The tool pliers 1 slide along the loading plate 51 onto the conveyor belt 411, and the conveyor belt 411 transports the tool pliers 1 one by one to the control panel 63.

[0075] In step S2, the laser quenching head 7 is turned on, and both laser quenching heads 7 face the two sides of the clamp blade of the tool clamp 1. Then, the moving frame 3 drives the laser quenching head 7 to slide along the length of the clamp blade to perform quenching treatment on the clamp blade.

[0076] In step S3, the linear drive mechanism 61 drives the control board 63 away from the guide plate 66. At this time, the quenched tool pliers 1 loses the support of the control board 63 and falls into the discharge port 67, and then falls onto the conveying mechanism 22 for collection.

[0077] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
