[0012] Preferably, the top of the support arc plate is fixedly connected to the bottom of the support frame, and the top of the hydraulic device is fixedly connected to the bottom of the support frame.

[0013] The production process of precision transmission components includes the following steps: S1: Place the metal plate to be stamped into the bottom die mechanism. The hydraulic main machine will first drive the punch rod to move downward, thereby driving the upper die base unit to perform a trial stamping on the metal plate to check the flatness of the metal plate. S2: Subsequently, the first mold block and the magnetic module will extend respectively, and the punch rod will strike downward again, thereby stamping and forming precision transmission components such as pin shafts. S3: The upper die module unit resets, and the waste or transmission components in the first mold notch will fall onto the bottom die mechanism. S4: The auxiliary mechanism will drive the precision transmission components and the metal plate waste after stamping to move to the unloading unit and achieve the collection of components and the separation of waste.

[0014] The beneficial effects of the present invention are as follows: 1. By setting the upper die base unit in the present invention, pressure sensors are provided at the four corners of the stamping plate. Before stamping production, the first micro electric cylinder and the second micro electric cylinder will be in the retracted state, so that the first mold block and the magnetic module are inside. The pressure sensors will detect whether the pressures at the four places of the metal plate are the same. If not, it means that the metal plate is not flat and has a curved surface. Using a metal plate with a curved surface for stamping will cause errors in the dimensions of the transmission components, so that they cannot reach the precision level. Then the stamping plate will press the metal plate for a long time to make it have no curved surface and be flat as a whole.

[0015] 2. By setting the upper die base unit in the present invention, during the upward reset process of the stamping plate, the magnetic module will attract the first magnetic block, so that the first magnetic block will extrude the transmission components that may be stuck in the first mold notch and fall onto the pressure receiving plate, which is convenient for subsequent collection.

[0016] 3. By setting the auxiliary mechanism in the present invention, the bottom pressure receiving plate is arranged on the moving slider that can move along the guide rod. After stamping, the servo motor will drive the reciprocating lead screw to rotate, so that the overall bottom die mechanism will move out of the outer shell frame and come into contact with the unloading unit to collect the precision components. At the same time, another metal plate is placed for re-stamping, avoiding the influence of the transmission components after previous stamping on subsequent stamping in the assembly line processing process.

[0017] 4. By setting the unloading unit in the present invention, during the movement of the moving slider, the insertion block on the baffle frame will be inserted into the slot on the limit block. Then the hydraulic device will retract the telescopic rod, thereby driving the pressure receiving plate to rotate around the rotating rod, so that the metal plate waste and the precision transmission components formed by stamping on the pressure receiving plate will both fall onto the isolation plate. The precision components will fall into the collection box for collection, and the waste will be blocked on the isolation plate, and the staff can take it for recycling later.

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example 1, using Figures 1-12 A precision punching machine and a process thereof for producing precision transmission parts according to an embodiment of the present invention are described as follows.

[0032] like Figures 1-3 As shown, the precision punching machine for producing precision transmission parts of the present invention comprises an outer frame 1, a tank 2 for storing hydraulic oil is arranged on the top of the outer frame 1, a hydraulic main engine 3 is arranged at the bottom of the tank 2, a punch rod 4 is arranged at the output end of the hydraulic main engine 3, and further comprises: An upper die base unit 5 is arranged at the bottom of the punch rod 4, an auxiliary unit 6 that cooperates with the upper die base unit 5 for punching, and a discharge unit 7 that is arranged at the auxiliary unit 6 and assists in discharging the precision transmission components; When the present invention is working, the metal plate is first placed on the auxiliary unit 6, and the auxiliary unit 6 drives the metal plate to move to the bottom of the upper die base unit 5. Then the hydraulic main engine 3 drives the punch 4 to move downward and enables the upper die base unit 5 to punch the metal plate, thereby producing a compact transmission component. Finally, the auxiliary unit 6 and the unloading unit 7 work together to collect the transmission components.

[0033] As shown Figures 3-6 in the figure, the upper die base unit 5 includes a first punching plate 51. Elastic dampers 52 are arranged at the four corners of the bottom of the first punching plate 51. A cushion column 53 is further arranged at the bottom of the first punching plate 51. A punching plate 54 is fixedly connected to the bottom of the cushion column 53. An elastic damper 56 is arranged between the punching plate 54 and the first punching plate 51. Pressure sensors 55 are arranged at the four corners of the bottom of the punching plate 54, which can check whether the four sides of the metal plate are warped during punching. Grinding tool notches 57 are evenly arranged at the bottom of the punching plate 54. A telescopic spring 58 is fixedly connected to the inner wall of the grinding tool notch 57. A magnetic block 59 is fixedly connected to the bottom of the telescopic spring 58. The outer surface of the magnetic block 59 is slidably connected to the inner wall of the grinding tool notch 57; The upper die base unit 5 further includes a micro electric cylinder 510 arranged on the inner wall of the punching plate 54. A grinding tool block 511 is fixedly connected to the output end of the micro electric cylinder 510. During punching, the micro electric cylinder 510 will drive the grinding tool block 511 to be in the extended state.

[0034] Pressure sensors 55 are arranged at the four corners of the punching plate 54. Before stamping production, the micro electric cylinder 510 and the micro electric cylinder 685 will be in the retracted state, so that the grinding tool block 511 and the magnetic module 686 are inside, and the metal plate to be punched is placed on the punching plate 54. Then, the hydraulic main engine 3 will drive the punch rod 4 to drive the whole upper die base unit 5 to move downward, so that the flat punching plate 54 punches the flat pressure receiving plate 681. The pressure sensors 55 will detect whether the pressures at the four places of the metal plate are the same. If not, it means that the metal plate is not flat and there is a bending surface. Using a metal plate with a bending surface for punching will cause errors in the dimensions of the transmission parts, so that the precision level cannot be achieved. Then, the punching plate 54 will press the metal plate for a long time to make it not generate a bending surface and be flat as a whole.

[0035] After the preliminary flattening, the micro electric cylinder 510 and the micro electric cylinder 685 will be in the extended state, so that during the pressing process of the metal plate, the grinding tool block 511 and the magnetic module 686 punch out precision transmission parts such as pin shafts. The precision transmission parts such as pin shafts punched out by the magnetic module 686 may get stuck in the grinding tool notch 57. During the upward reset process of the punching plate 54, the magnetic module 686 will attract the magnetic block 59, so that the magnetic block 59 will extrude the transmission parts that may be stuck in the grinding tool notch 57 and drop them onto the pressure receiving plate 681.

[0036] The outer surface of the outer frame 1 is fixedly connected to an instrument display device 12 provided with a brake button one 8. On one side of the outer frame 1 away from the instrument display device 12, there is a brake button two 9. At the bottom of the outer frame 1, there is also a lower die base 10, and the top of the lower die base 10 is fixedly connected to an elastic buffer base 11 with a specific inner groove.

[0037] The top of the first punching plate 51 is fixedly connected to the bottom of the punching rod 4, and the outer surface of the hydraulic main engine 3 is fixedly connected to the inner wall of the outer frame 1.

[0038] As Figure 7 shown, the auxiliary unit 6 includes a support frame 61. One end of the support frame 61 is fixedly connected to a servo motor 62. The output end of the servo motor 62 is fixedly connected to a reciprocating lead screw 63. The outer surface of the reciprocating lead screw 63 is threadedly connected to a moving slider 64. One end of the moving slider 64 away from the reciprocating lead screw 63 is slidably connected to a guide rod 65. On the outer surface of the moving slider 64, there are symmetrically arranged support plates one 66. One end of the support plate one 66 away from the moving slider 64 is rotatably connected to a rotating rod 67. One end of the rotating rod 67 away from the support plate one 66 is fixedly connected to a bottom die mechanism 68.

[0039] By arranging the bottom pressure plate 681 at the bottom on the moving slider 64 that can move along the guide rod 65, after stamping, the servo motor 62 will drive the reciprocating lead screw 63 to rotate, so that the overall bottom die mechanism 68 moves out of the outer shell frame and contacts the unloading unit 7 to collect precision components. At the same time, another metal plate is placed for re-stamping, avoiding the influence of the previously stamped transmission components on the subsequent stamping during the assembly line processing.

[0040] One end of the support frame 61 is fixedly connected to the outer surface of the outer frame 1, and both ends of the guide rod 65 are fixedly connected to the inner wall of the support frame 61.

[0041] As Figures 8-9 shown, the bottom die mechanism 68 includes a pressure plate 681. The bottom of the pressure plate 681 is evenly provided with limit blocks 682 adapted to the inner grooves of the elastic buffer base 11. On one side of the limit block 682 close to the unloading unit 7, there is a slot 683. The top of the pressure plate 681 is evenly provided with grinding tool notches two 684 corresponding to the grinding tool block one 511. The inner wall of the pressure plate 681 is fixedly connected to a micro electric cylinder two 685. The output end of the micro electric cylinder two 685 is fixedly connected to a magnetic module 686 corresponding to the module notch one.

[0042] Both ends of the pressure plate 681 are fixedly connected to the rotating rods 67 on both sides. The magnetic module 686 attracts the magnetic block one 59, and the outer surface of the limit block 682 is slidably connected to the outer surface of the elastic buffer base 11.

[0043] The specific working process is as follows: During operation, first, the first micro electric cylinder 510 and the second micro electric cylinder 685 will be in the retracted state, so that the first grinding block 511 and the magnetic module 686 are inside. Then, the metal plate to be stamped is placed on the stamping plate 54. After that, the hydraulic main machine 3 drives the punch rod 4 to drive the overall upper die base unit 5 to move downward, so that the flat stamping plate 54 stamps the flat pressure receiving plate 681. The pressure sensor 55 will detect whether the pressures at the four places of the metal plate are the same. If not, the stamping plate 54 will press the metal plate for a long time to prevent it from having a curved surface and keep it flat. After the initial flattening, the first micro electric cylinder 510 and the second micro electric cylinder 685 will be in the extended state, so that the first grinding block 511 and the magnetic module 686 stamp out precision transmission parts such as pin shafts during the pressing process of the metal plate. During the upward reset process of the stamping plate 54, the magnetic module 686 attracts the first magnetic block 59, so that the first magnetic block 59 extrudes the transmission parts that may be stuck in the first grinding notch 57 and drops them onto the pressure receiving plate 681.

[0044] Example 2, using Figures 1-12 A precision punch and its process for the production of precision transmission parts according to an embodiment of the present invention will be described as follows.

[0045] As Figures 10-11 shown, the precision punch for the production of precision transmission parts of the present invention, on the basis of Embodiment 1, the unloading unit 7 includes a support arc plate 71. One end of the support arc plate 71 is fixedly connected with a hydraulic device 72. An arc-shaped telescopic rod 73 is arranged on the hydraulic device 72. The output end of the telescopic rod 73 is fixedly connected with a second support plate 74. The top of the second support plate 74 is fixedly connected with a support column 75. The top of the support column 75 is fixedly connected with a blocking frame 76. Insertion blocks 77 corresponding to the insertion slots 683 one by one are uniformly arranged on the outer surface of the blocking frame 76. The bottom of the support arc plate 71 is fixedly connected with a first connection plate 78. The bottom of the first connection plate 78 is fixedly connected with a partition plate 79. The gap provided by the partition plate 79 blocks the waste generated by the stamping of the metal plate. Second connection plates 710 are symmetrically arranged on both sides of the partition plate 79. The bottom of the second connection plate 710 is fixedly connected with a collection box 711.

[0046] The metal plate waste and the precision transmission parts formed by stamping on the pressure receiving plate 681 both fall onto the partition plate 79. The precision parts will fall into the collection box 711 for collection, while the waste will be blocked on the partition plate 79.

[0047] The top of the support arc plate 71 is fixedly connected with the bottom of the support frame 61, and the top of the hydraulic device 72 is fixedly connected with the bottom of the support frame 61.

[0048] The specific working process is as follows: During the movement of the moving slider 64, the insertion block 77 on the blocking frame 76 will insert into the slot 683 on the limiting block 682. Then, the hydraulic device 72 will retract the telescopic rod 73, thereby driving the pressure-receiving plate 681 to rotate around the rotating rod 67, causing the metal plate waste and the precision transmission components formed by stamping on the pressure-receiving plate 681 to fall onto the isolation plate 79. The precision components will fall into the collection box 711 for collection, while the waste will be blocked on the isolation plate 79 for the staff to pick up and recycle later.

[0049] As Figure 12 shown, the production process of precision transmission components includes the following steps: S1: Place the metal plate to be stamped into the bottom die mechanism 68. The hydraulic main machine 3 will first drive the punch rod 4 to move downward, thereby driving the upper die seat unit 5 to perform a trial stamping on the metal plate to check the flatness of the metal plate. S2: Then, the first mold block 511 and the magnetic module 686 will extend respectively, and the punch rod 4 will strike downward again, so that precision transmission components such as pin shafts are formed by stamping. S3: The upper die module unit resets, and the waste or transmission components in the first mold notch 57 fall onto the bottom die mechanism 68. S4: The auxiliary mechanism will drive the precision transmission components after stamping and the metal plate waste to move to the unloading unit 7 to achieve the collection of components and the separation of waste.

[0050] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
