Description

Technical Field

[0001] The present invention belongs to the technical field of motor punching dies, and specifically relates to a motor punching die. Background Art

[0002] A motor is composed of two parts, a rotor and a stator. The stator punching sheet is an important part of the motor iron core. The punching sheet is stamped from 0.3 mm silicon steel sheets. With the continuous progress of modern technology, punching sheets of different specifications can be manufactured, so as to be suitable for the use of motor stators and rotors with different powers. During the production process of the punching sheet, generally, a stamping device is used to stamp the silicon steel sheet, so as to form the punching sheet style desired by people. At present, after the stamping is completed, since the punching sheet is in a die set and is directly below the stamping mechanism, when taking it out, people need to reach in to take it out, and it is somewhat dangerous to take away the punching sheet from below the stamping mechanism.

[0003] In the existing stamping dies during processing, when the iron core punching sheet is stamped into the motor iron core, the waste material falls from the stamping groove, but the formed product, the motor iron core, is still on the stamping station, and it needs to be taken out manually, which is rather troublesome and affects the processing efficiency.

[0041] The beneficial effects of the present invention are as follows:

[0042] 1. By providing an auxiliary mechanism, when the rubber rod is stuck in the hole, pressure can be applied to insert the rubber rod into the hole, thereby increasing the pushing force on the material, separating the material from the surface of the lower mold and then conveying it, enabling the material to be quickly conveyed out. At this time, the worker receives the material from one side and then extracts it, reducing the danger when manually reaching under the mold to remove the material, and also reducing the friction between the material and the lower mold during downward conveyance, protecting the accuracy of the lower mold.

[0043] 2. By providing a buffer mechanism, the top of the blanking assembly contacts the lower mold and rotates with the lower mold. Eventually, the bottom of the lower mold contacts the top of the buffer assembly and presses downward. When the buffer assembly moves to the bottommost position, punching is performed to buffer and protect the lower mold, and to detect whether the force between the lower mold and the upper mold is uniform. The blanking assembly cleans and discharges the broken materials in the holes of the lower mold, preventing waste from jamming in the holes of the lower mold and causing obstacles to subsequent punching.

[0044] 3. By providing a blanking assembly, the lower mold is lifted upward under the action of the telescopic column, causing the collecting plate to be in an inclined state under the action of the spring. After the fragments generated by punching are concentrated on the collecting plate, they are conveyed by the collecting plate into the collecting groove, preventing the fragments from jamming on the inner wall of the lower mold and causing blockage, so that it cannot work continuously for a long time and affect the punching efficiency.

[0045] 4. By providing a buffer assembly, under the action of the impact force during punching, the extrusion force on the air is increased. Eventually, the cover shell and the fixed column are combined, so that when the upper and lower molds are closed and stamped, the lower mold is buffered, reducing the hard impact force on the lower mold. And by providing multiple groups of contact sensors to detect whether the force between the upper and lower molds is uniform and whether they reach the same plane at the same time, it can further check whether the upper and lower molds are completely closed, strengthening the protection of the lower mold and enabling the worker to quickly judge whether the situation between the upper and lower molds is suitable for continued processing.

Detailed implementation manners

[0055] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners. The embodiments of the present invention are given for the purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0057] Including:

[0058] Workbench 1, the inner wall of the workbench 1 is provided with a collection tank 2, and the bottom of the inner wall of the workbench 1 is provided with a working tank 3;

[0059] Buffer mechanism 4, the buffer mechanism 4 is installed at the bottom of the inner wall of the working tank 3, and the buffer mechanism 4 is used to assist in collecting the waste of the punching sheet;

[0060] The lower die mechanism 5 is placed on top of the buffer mechanism 4, and the bottom of the lower die mechanism 5 is installed at the bottom of the inner wall of the working groove 3;

[0061] The upper die mechanism 6 is installed on top of the lower die mechanism 5, and the top of the upper die mechanism 6 is connected to the top of the inner wall of the workbench 1;

[0062] The auxiliary mechanism 7 is symmetrically installed at the bottom of the inner wall of the workbench 1. The bottom of the auxiliary mechanism 7 is rotatably connected to the bottom of the inner wall of the workbench 1. The auxiliary mechanism 7 is used to separate the stamped sheet material from the lower die mechanism 5.

[0063] During operation, the worker installs the upper die mechanism 6 at the top of the inner wall of the workbench 1 and installs the lower die mechanism 5 at the bottom of the inner wall of the working groove 3, so that the upper die mechanism 6 and the lower die mechanism 5 can completely cover and cooperate with each other. Then, the material is placed in the middle. During stamping, first close the upper die mechanism 6 and the lower die mechanism 5, and then perform punching on it, so that the punched scraps enter the buffer mechanism 4 for collection. The auxiliary mechanism 7 helps the material to be lifted from the lower die mechanism 5 and conveyed outwards, so that the worker can take out the material from the edge without reaching his hand under the die.

[0064] The lower die mechanism 5 includes:

[0065] The telescopic columns 501 are uniformly arranged at the bottom of the inner wall of the working groove 3;

[0066] The lower die 502 is installed on top of the telescopic columns 501. Grooves 503 are uniformly opened on both sides of the lower die 502. The inner side of the groove 503 fits with the edge of the clamping plate 702, so that the clamping plate 702 can be on the same horizontal plane as the lower die 502. After stamping is completed, as the lower die 502 moves, the material is stuck on the clamping plate 702.

[0067] The upper die mechanism 6 includes:

[0068] The guide rods 601 are uniformly arranged on top of the lower die 502;

[0069] The inner wall of the upper die 602 is slidably connected to the outer wall of the guide rod 601. Connecting blocks 603 are symmetrically arranged on the top of the upper die 602. First cylinders 604 are uniformly arranged on the top of the connecting blocks 603. The first cylinders 604 are installed on the top of the inner wall of the workbench 1.

[0070] The upper die mechanism 6 further includes:

[0071] The second cylinders 605 are uniformly installed on the top of the inner wall of the workbench 1, and the second cylinders 605 are located in the middle of the workbench 1;

[0072] The mounting block 606 is uniformly arranged at the bottom of the second cylinder 605;

[0073] The punch 607 is uniformly arranged at the bottom of the mounting block 606, and the outer wall of the punch 607 is sleeved with the inner wall of the upper die 602.

[0074] During use, the first cylinder 604 drives the connecting block 603 to press the upper die 602 downward, so that the upper die 602 moves along the guide rod 601 and finally closes with the lower die 502 to clamp and press the material. Subsequently, the second cylinder 605 drives the punch 607 to pass through the upper die 602 and punch the lower die 502 to punch holes in the surface of the material.

[0075] The buffer mechanism 4 includes:

[0076] The rotating rod 401, and both ends of the rotating rod 401 are rotatably connected to the inner wall of the working groove 3;

[0077] The blanking assembly 402 is installed on the outer wall of the rotating rod 401, and springs 403 are symmetrically arranged at the bottom of the blanking assembly 402, and the bottoms of the springs 403 are connected to the bottom of the inner wall of the working groove 3;

[0078] The buffer assemblies 404 are uniformly arranged on both sides of the blanking assembly 402, and the bottoms of the buffer assemblies 404 are connected to the bottom of the inner wall of the working groove 3.

[0079] The springs 403 and the rotating rod 401 keep the blanking assembly 402 in an inclined state. When the lower die 502 is pressed and moves downward, the top of the blanking assembly 402 contacts the lower die 502 and rotates with the lower die 502. Finally, the bottom of the lower die 502 contacts the top of the buffer assembly 404 and presses downward. When the buffer assembly 404 moves to the bottommost position, punching is performed to buffer and protect the lower die 502, and to detect whether the force between the lower die 502 and the upper die 602 is uniform. The blanking assembly 402 cleans and discharges the broken materials in the holes of the lower die 502 to prevent waste from getting stuck in the holes of the lower die 502 and causing obstacles to subsequent punching.

[0080] The auxiliary mechanism 7 includes:

[0081] The rotating frame 701, the bottom of the rotating frame 701 is rotatably connected to the bottom of the inner wall of the workbench 1, and a clamping plate 702 is arranged at the top of the rotating frame 701, and the outer wall of the clamping plate 702 is clamped with the outer wall of the lower die 502;

[0082] The bearing bracket 703 is symmetrically arranged on the top of the clamping plate 702. The bottom of the bearing bracket 703 is rotatably connected to the top of the clamping plate 702. The outer wall of the rubber rod 706 is sleeved with the inner wall of the bearing bracket 703, enabling the rubber rod 706 to move up and down in the bearing bracket 703;

[0083] The limiting rod 704 is installed on the top of the bearing bracket 703. A counterweight 705 is arranged on the outer wall of the limiting rod 704, and the inner wall of the counterweight 705 is sleeved with the outer wall of the limiting rod 704;

[0084] The rubber rod 706 is evenly arranged at the bottom of the counterweight 705. The bottom of the rubber rod 706 is uneven and is made of rubber material with relatively small elasticity.

[0085] After the material punching is completed, the upper and lower dies 502 are separated. At this time, the rotating frame 701 rises to separate the clamping plate 702 from the bottom to separate the material from the lower die 502. Subsequently, the bearing bracket 703 rotates to drive the rubber rod 706 to contact the top of the material, and based on the friction between the material and the rubber rod 706, the material is driven by the rubber rod 706 to be conveyed outwards. The counterweight 705 causes the rubber rod 706 to be subjected to a downward pressure. When the rubber rod 706 gets stuck in the hole, it can apply pressure to insert the rubber rod 706 into the hole, thereby increasing the pushing force on the material, separating the material from the surface of the lower die 502 and then conveying it, enabling the material to be conveyed out quickly. At this time, the worker receives the material from one side and pulls it out, reducing the danger when manually reaching under the die to take out the material, and also reducing the friction between the material and the lower die 502 when the material is conveyed downwards, protecting the accuracy of the lower die 502.

[0086] Embodiment 2, please refer to Figures 1 - 8 , the present invention provides a technical solution: on the basis of Embodiment 1, the blanking assembly 402 includes:

[0087] The driving seats 4021 are evenly arranged at the bottom of the inner wall of the working groove 3. The lifting rods 4022 are installed on the tops of the driving seats 4021, and the retaining plates 4023 are arranged on the outer walls of the lifting rods 4022;

[0088] The mounting rods 4024 are arranged on the tops of the lifting rods 4022.

[0089] The blanking assembly 402 further includes:

[0090] The collecting plate 4026 has its bottom connected to the outer wall of the rotating rod 401. The bottom of the collecting plate 4026 at the end away from the collecting groove 2 is connected to the top of the spring 403. The top of the collecting plate 4026 is evenly provided with movable holes 4027 through which the lifting rods 4022 extend upwards. The collecting plate 4026 is placed obliquely;

[0091] The insertion rod 4025 is evenly arranged at the top of the installation rod 4024. The position of the insertion rod 4025 corresponds to the position of the punch 607. The diameter of the insertion rod 4025 is smaller than the aperture of the punching hole, and the insertion rod 4025 is made of hard metal material.

[0092] After stamping, the driving seat 4021 drives the lifting rod 4022 to rise, inserts the insertion rod 4025 into the punching hole, vibrates and cleans the debris stuck on the inner wall, so that it falls on the collecting plate 4026. After stamping is completed, the lower die 502 is lifted upward under the action of the telescopic column 501, so that the collecting plate 4026 is affected by the spring 403 and forms an inclined state. After the debris generated by punching is concentrated on the collecting plate 4026, it is conveyed to the collecting groove 2 by the collecting plate 4026, avoiding the blockage caused by the debris stuck on the inner wall of the lower die 502, making it unable to work continuously for a long time and affecting the punching efficiency.

[0093] The buffer assembly 404 includes:

[0094] The fixed column 4041, the bottom of the fixed column 4041 is connected to the bottom of the inner wall of the working groove 3. The outer wall of the fixed column 4041 is symmetrically provided with sliding grooves 4047. The top of the fixed column 4041 is sleeved with a housing 4042. The inner wall of the housing 4042 is slidably connected to the outer wall of the fixed column 4041. The inner wall of the housing 4042 and the top of the fixed column 4041 form a relatively sealed space, and the air inside is slowly squeezed out;

[0095] The contact inductor 4045 is arranged at the top of the inner wall of the housing 4042.

[0096] The buffer assembly 404 further includes:

[0097] The air inlet hole 4046 is opened at the central axis of the fixed column 4041. The edge of the inner wall of the fixed column 4041 is provided with a threaded air outlet hole 4044. The aperture of the air inlet hole 4046 is larger than the aperture of the air outlet hole;

[0098] The piston rod 4043, the bottom of the piston rod 4043 is connected to the inner wall of the workbench 1. An air inlet groove 4048 is opened on one side of the workbench 1 close to the piston rod 4043. The outer wall of the piston rod 4043 is slidably connected to the inner wall of the air inlet groove 4048. The upper part of the air inlet groove 4048 is kept sealed. When the air in the air inlet groove 4048 is squeezed out, an air pump is connected to the inside of the workbench 1 to keep the air inlet groove 4048 inflated when the piston rod 4043 moves downward.

[0099] At the beginning, under the drive of the telescopic column 501, the lower mold 502 approaches the housing 4042. At this time, the piston rod 4043 squeezes the air in the air inlet groove 4048 upward into the internal space between the fixed column 4041 and the housing 4042, causing the housing 4042 to move away from the fixed column 4041 under the action of air pressure. At this time, the upper mold 602 and the lower mold 502 are closed. Driven by the first cylinder 604, the lower mold 502 contacts the top of the housing 4042 and continues to move downward. At this time, the telescopic column 501 retracts. When the second cylinder 605 drives the punch 607 to punch holes, the housing 4042 is finally pressed downward to contact the top of the fixed column 4041, causing the contact sensor to sense the contact with the fixed column 4041;

[0100] After the piston rod 4043 squeezes the air into the space between the fixed column 4041 and the housing 4042, when the piston rod 4043 remains stationary, the air in the housing 4042 flows out through the threaded air outlet hole 4044. Since the aperture of the threaded air outlet hole 4044 is small and the length is long, the speed of the air squeezed out of the housing 4042 is slow. As a result, the speed of the housing 4042 moving downward slows down, so that the lower mold 502 moves downward slowly during the process of being squeezed by the upper mold 602, and is subjected to an impact force during punching, increasing the squeezing force on the air. Finally, the housing 4042 and the fixed column 4041 are combined, so that when the upper and lower molds 502 are closed and stamped, the lower mold 502 is buffered, reducing the hard impact force received by the lower mold 502, and multiple groups of contact sensors 4045 are provided to detect whether the force between the upper and lower molds 502 is uniform and whether they reach the same plane at the same time, so as to check whether the upper and lower molds 502 are completely closed, strengthen the protection of the lower mold 502, and enable the worker to quickly judge whether the situation between the upper and lower molds 502 is suitable for continued processing.

[0101] The specific working process is as follows:

[0102] During work, the worker installs the upper mold mechanism 6 at the top end of the inner wall of the workbench 1 and installs the lower mold mechanism 5 at the bottom of the inner wall of the working groove 3, so that the upper mold mechanism 6 and the lower mold mechanism 5 can completely cover and cooperate with each other. Subsequently, the material is placed in the middle. When in use, the first cylinder 604 drives the connecting block 603 to press the upper mold 602 downward, so that the upper mold 602 moves along the guide rod 601 and finally closes with the lower mold 502, clamping and pressing the material. Subsequently, the second cylinder 605 drives the punch 607 to pass through the upper mold 602 and punch the lower mold 502 to punch holes in the surface of the material;

[0103] During use, the first cylinder 604 drives the connecting block 603 to press the upper die 602 downward, causing the upper die 602 to move along the guide rod 601 and finally close the mold with the lower die 502, clamping and pressing the material. Subsequently, the second cylinder 605 drives the punch 607 to pass through the upper die 602 and punch the lower die 502, punching holes in the surface of the material, and causing the punched scraps to enter the buffer mechanism 4 for collection;

[0104] After the material punching is completed, the upper and lower dies 502 are separated. At this time, the rotating frame 701 rises to separate the clamping plate 702 from the bottom to separate the material from the lower die 502. Subsequently, the supporting bracket 703 rotates to drive the rubber rod 706 to contact the top of the material, and conveys the material outward according to the friction force between the material and the rubber rod 706. The counterweight 705 causes the rubber rod 706 to receive a downward pressure. When the rubber rod 706 is stuck in the hole, pressure can be applied to insert the rubber rod 706 into the hole, thereby increasing the pushing force on the material, separating the material from the surface of the lower die 502 and then conveying it, enabling the material to be conveyed out quickly. At this time, the worker receives the material from one side and pulls it out.

[0105] 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.
