Description

TECHNICAL FIELD

[0003] The document with the publication number CN113369408B discloses a servo punch press stamping strength adjusting mechanism and a use method thereof, which comprises a punch press body. An upper punch block is arranged on the upper part of the workbench corresponding to the punch press body. A blocking module is fixedly connected to the top surface of the workbench of the punch press body. The blocking module comprises a fixed plate. Connection grooves are formed in the top surfaces of both sides of the fixed plate. Connection rods are slidably connected to the inner sides of the connection grooves.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, by setting up a feeding component, the reverse meshing of the drive rack and transmission gear during the resetting process of the stamping module, combined with the ratchet mechanism, achieves unidirectional power transmission. This allows the feeding roller to quantitatively feed the metal sheet only during the stamping return phase through mechanical transmission, ensuring that the feeding action and stamping rhythm are strictly synchronized after each stamping, avoiding timing differences similar to those in traditional feeding methods. This improves the mechanization and automation of the component and ensures that the feeding amount is the same each time, increasing the stamping utilization rate of the metal sheet and reducing material consumption. Furthermore, by using a movable cylinder to adjust the meshing position of the linkage gear in the transmission gear set, the speed ratio of the transmission system can be quickly changed without replacing the hardware, precisely controlling the rotation angle of the feeding roller. This changes the amount of movement of the metal sheet driven by the feeding roller, thereby changing the feeding amount of the metal sheet to meet different stamping processing requirements and improving the overall applicability of the device.

[0028] 2. In this invention, by setting up a sorting component, the finished product passes through the discharge hole and the detection sensor. The detection sensor detects the finished product. If the finished product is qualified, the drive motor does not start, and the sorting plate remains stationary, allowing the qualified finished product to be discharged from the right side. If the finished product is unqualified, the drive motor starts, and the detection sensor identifies the finished product. In conjunction with the drive motor, the sorting plate swings left and right to achieve automatic sorting of the finished product. Unqualified finished products are sorted and eliminated, improving the yield rate of finished products. Furthermore, through the mechanical cooperation between the vibration motor and the vibration spring, the sliding channel is vibrated at high speed, improving the material feeding efficiency and the smoothness of the material feeding.

[0029] 3. In this invention, by setting a limit adjustment component, the knob adjusts the lead screw, lead screw seat, and both sides of the metal sheet of the bonding plate for bonding and positioning. At the same time, the electric push rod drives the feeding rollers downward through the moving box, rotating sleeve, first bevel gear, and second bevel gear, so that the two feeding rollers bond the metal sheet in the vertical direction, thereby positioning and limiting the metal sheet in the vertical direction. Through the positioning of the metal sheet by the two bonding plates and the two feeding rollers, the metal sheet can be placed on the forming mold in an accurate posture, avoiding the metal sheet from shifting during stamping and causing accidental damage to the metal sheet. This improves the stamping utilization rate of the metal sheet and saves stamping costs. At the same time, during the movement of the moving box, the moving box, in conjunction with the rotating sleeve, drives the first bevel gear and the second bevel gear to move in the vertical direction, thereby maintaining the linkage relationship between the two feeding rollers and ensuring the relative rotation between the two feeding rollers.

[0043] 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.

[0044] Please see Figures 1-11 The present invention provides a technical solution:

[0045] A punch press with a material unloading and sorting mechanism includes a main body 1, a punching module 3 below the main body 1, a base 6 connected to the bottom of the main body 1, a processing table 5 connected to the top of the base 6, a limit adjustment component 4 and a feeding component 9 respectively on the top of the processing table 5, a sorting component 7 at the bottom of the processing table 5, a hydraulic device 2 connected to the bottom of the main body 1, the bottom of the hydraulic device 2 and the punching module 3, and a forming mold 8 on the top of the processing table 5.

[0046] The feeding assembly 9 includes two sets of opposing support groups. Two relatively rotating feeding rollers 904 are installed within each support group. A rotating shaft 913 is connected to one side of the lower feeding roller 904. A fixed housing 905 is connected to one side of the main body 1 via a fixed base. One end of the rotating shaft 913 extends into the fixed housing 905 and is connected to a speed-changing gear set 914. A drive gear 916 and a transmission gear 906 for driving the rotating shaft 913 are installed on one side of the speed-changing gear set 914. Two drive racks 907 are installed on one side of the stamping module 3. One side of the drive racks 907 meshes with one side of the transmission gears 906. The drive gear 916, in conjunction with the speed-changing gear set 914, adjusts the feeding rollers 904. The feeding stroke is as follows: a connecting shaft is rotatably connected inside the fixed box 905; a drive gear 916 is slidably connected to the connecting shaft, and the connection can drive the drive gear 916 to rotate; a transmission gear 906 is rotatably connected to the outer surface of the connecting shaft; a linkage gear 915 is meshed with one side of the drive gear 916; the linkage gear 915 is meshed with the speed change gear set 914; both sides of the linkage gear 915 are rotatably connected to connecting frames, and the other end of the connecting frame is sleeved with the outer surface of the connecting shaft; the transmission gear 906 has an inner cavity, and a rotating disk 920 is rotatably connected inside the inner cavity; the rotating disk 920 is connected to the outer surface of the connecting shaft; a lever 919 is rotatably connected to one side of the rotating disk 920; and one side of the lever 919 is in contact with... There is a fixed block 917 with an L-shaped cross-section. A return spring 918 is connected to one side of the actuating lever 919, and the other end of the return spring 918 is connected to one side of the fixed block 917. A ratchet ring 921 is connected inside the cavity, and the actuating lever 919 is in contact with the ratchet ring 921. A connecting seat 912 is rotatably connected to the top of the linkage gear 915. A stroke rod 911 is connected to one side of the connecting seat 912. A stroke groove 909 is opened on one side of the fixed box 905, and the stroke rod 911 is slidably connected to the stroke groove 909. The stroke groove 909 is obliquely set. A movable cylinder 908 is obliquely installed on one side of the fixed box 905. One end of the output shaft of the movable cylinder 908 is connected to a connecting rod 910. One side of 910 is sleeved with the side of the stroke rod 911. The top of the drive rack 907 is connected to a sliding plate 902. One side of the sliding plate 902 is in contact with one side of the main body device 1. Two sliding sleeves are connected to one side of the main body device 1. The sliding plate 902 is slidably connected in the sliding sleeve. The top of the two sliding plates 902 is connected to the same connecting horizontal plate 901. One side of the connecting horizontal plate 901 is connected to one side of the stamping module 3. The speed change gear set 914 includes multiple gears with different diameters and different numbers of teeth. The bracket set includes two fixed brackets 903 arranged opposite each other. The bottom of the fixed brackets 903 is connected to the top of the processing table 5. Two feed rollers 904 are rotatably connected between the two fixed brackets 903.

[0047] The specific implementation method is as follows: By setting up the feeding component 9, during the resetting process of the stamping module 3, the drive rack 907 and the transmission gear 906 engage in reverse, and together with the ratchet mechanism, unidirectional power transmission is achieved. This allows the feeding roller 904 to quantitatively feed the metal sheet only through mechanical transmission during the stamping return phase, ensuring that the feeding action and stamping rhythm are strictly synchronized after each stamping, avoiding timing differences similar to those in traditional feeding, improving the mechanization and automation of the component, and ensuring that the feeding amount is the same each time, improving the stamping utilization rate of the metal sheet, reducing material consumption, and using the movable cylinder 908 to adjust the linkage gear 915 in... The meshing position in the gear set 914 allows for rapid changes in the transmission ratio without hardware replacement, precisely controlling the rotation angle of the feed roller 904. This alters the amount of movement of the metal sheet driven by the feed roller 904, thereby changing the feed amount of the metal sheet to meet different stamping requirements and improving the overall applicability of the device. The self-locking characteristic of the recording mechanism, composed of the ratchet ring 921, the actuating lever 919, and the transmission gear 906, completely eliminates feed back phenomenon. It works in conjunction with the first bevel gear 409, the second bevel gear 410, the third bevel gear 411, and the fourth bevel gear 412 to drive the metal sheet feeding.

[0048] The limit adjustment assembly 4 includes two opposing fixed support plates 401. Two opposing fitting plates 404 are provided on the top of the fixed support plates 401. A movable box 413 is slidably connected inside the fixed bracket 903. A rotating sleeve 408 is vertically rotatably connected inside the movable box 413. A rotating rod 406 is slidably connected inside the rotating sleeve 408. A second bevel gear 410 is connected to the outer surface of the rotating sleeve 408. A first bevel gear 409 is meshed with one side of the second bevel gear 410. The first bevel gear 409 is connected to one side of the upper feed roller 904 via a first rotating shaft. A cavity is opened on one side of the fixed bracket 903. One end of the rotating rod 406 extends into the cavity and is connected to a third bevel gear 411. The bottom of the third bevel gear 411 is meshed with a... The fourth bevel gear 412 has one side connected to the feed roller 904 located below via the second rotating shaft. One end of the connecting shaft extends into the cavity and is connected to the fourth bevel gear 412. The top of the movable box 413 is connected to two symmetrically arranged electric push rods 407. The other end of the electric push rods 407 is connected to one side of the fixed bracket 903. The top of the fixed support plate 401 is provided with a sliding groove 403. An adjusting screw 402 is rotatably connected in the sliding groove 403. The adjusting screw 402 is symmetrically arranged along the center position, and the threads on both sides are opposite. The outer surface of the adjusting screw 402 is connected to two symmetrically arranged screw seats 405. The screw seats 405 are slidably connected to the sliding groove 403. The top of the screw seats 405 is connected to a bonding plate 404.

[0049] The specific implementation method is as follows: By setting the limit adjustment component 4, the knob adjusts the lead screw 402, lead screw seat 405, and bonding plate 404 to position the metal sheet on both sides. At the same time, the electric push rod 407 drives the feed roller 904 downward through the moving box 413, rotating sleeve, first bevel gear 409, and second bevel gear 410, so that the two feed rollers 904 are vertically bonded to the metal sheet, thereby vertically positioning and limiting the metal sheet. The two bonding plates 404 and the two feed rollers 904 are used to position and limit the metal sheet. The positioning of the metal sheet allows it to be placed accurately on the forming mold 8, preventing accidental damage caused by metal sheet misalignment during stamping. This improves the stamping utilization rate of the metal sheet and saves stamping costs. Meanwhile, during the movement of the moving box 413, the moving box 413, in conjunction with the rotating sleeve 408, drives the first bevel gear 409 and the second bevel gear 410 to move in the vertical direction, thereby maintaining the linkage between the two feed rollers 904 and ensuring the relative rotation between the two feed rollers 904.

[0050] The sorting assembly 7 includes a sliding channel 701 capable of relative vibration. The sliding channel 701 is located below the processing table 5, with one side of the sliding channel 701 angled. A sorting plate 705 is rotatably connected inside the sliding channel 701. A drive motor 706 is connected to the bottom of the sliding channel 701 via a mounting plate. One end of the output shaft of the drive motor 706 extends into the sliding channel 701 and connects to the bottom of the sorting plate 705. A partition plate 702 for separating space is provided inside the sliding channel 701. A material drop hole is opened at the center of the processing table 5. A detection sensor 704 for detecting defects is connected to the bottom of the processing table 5. Vibration springs 703 are connected to all four sides of the bottom of the sliding channel 701. The other end of the vibration springs 703 is connected to the bottom of the base 6. Vibration motors 707 are connected to both sides of the bottom of the sliding channel 701.

[0051] The specific implementation method is as follows: By setting up the sorting component 7, the finished product passes through the discharge hole and the detection sensor 704. The detection sensor 704 detects the finished product. If the finished product is qualified, the drive motor 706 does not start, and the sorting plate 705 remains stationary, so that the qualified finished product is discharged from the right side. If the finished product is unqualified, the drive motor 706 starts, and the detection sensor 704 identifies the finished product. In conjunction with the drive motor 706 driving the sorting plate 705 to swing left and right, the finished product is automatically sorted. Unqualified finished products are sorted and eliminated, improving the yield rate of finished products. Furthermore, through the mechanical cooperation between the vibration motor 707 and the vibration spring 703, the sliding channel 701 is vibrated at high speed, improving the material feeding efficiency and the smoothness of material feeding.

[0052] Working principle: During use, the operator places the metal sheet for stamping on the fixed support plate 401 and passes the metal sheet between the two feed rollers 904. Then, the operator turns the knob, which drives the adjusting screw 402 to rotate. The adjusting screw 402 drives the screw seat 405 to slide relative to each other in the sliding groove 403. The two screw seats 405 move relative to each other, and the screw seats 405 drive the bonding plate 404 to move relative to each other, so that the bonding plate 404 can bond and position the two sides of the metal sheet. Then, the operator starts the electric push rod 407, which drives the moving box 413 to move downward. The moving box 413 drives the rotating sleeve, the first bevel gear 409, the second bevel gear 410 and the feed rollers 904 to move downward, so that the two feed rollers 904 can bond the metal sheet vertically, thereby positioning and limiting the metal sheet vertically. The positioning of the metal sheet is achieved by the two bonding plates 404 and the two feed rollers 904.

[0053] After the metal sheet is placed and positioned, the operator starts the hydraulic device 2. The hydraulic device 2 drives the stamping module 3 to move downward and cooperates with the metal sheet of the forming mold 8 to form and stamp. The formed finished product passes through the material discharge hole and the detection sensor 704. The detection sensor 704 detects the finished product. If the finished product is qualified, the drive motor 706 does not start and the sorting plate 705 remains stationary, so that the qualified finished product is discharged from the right side. If the finished product is unqualified, the drive motor 706 starts and drives the sorting plate 705 to rotate to the right side, so that the unqualified finished product is discharged from the left side. During this process, the vibration motor 707, together with the vibration spring 703, drives the sliding channel 701 to vibrate, thereby accelerating the finished product to slide out, thus avoiding the accumulation and blockage of finished products and improving the finished product discharge efficiency.

[0054] During the stamping of the metal sheet, the stamping module 3 moves the connecting horizontal plate 901 downwards, which in turn moves the sliding plate 902 downwards. The sliding plate 902 then moves the drive rack 907 downwards, causing the drive rack 907 to rotate the transmission gear 906. At this time, the ratchet mechanism inside the transmission gear 906 is not operating, allowing the transmission gear 906 to idle and not rotate the connecting shaft. After the stamping module 3 completes the stamping, it performs a reset motion under the drive of the hydraulic device 2. At this time, the drive rack 907 drives the transmission gear 906 to rotate in the opposite direction. The transmission gear 906 then rotates the internal... The ratchet ring 921 rotates, causing the actuating lever 919 to move. The actuating lever 919, limited by the fixed block 917, causes the rotating disk 920 to rotate. The rotating disk 920 causes the connecting shaft to rotate, which in turn causes the drive gear 916 to rotate. The drive gear 916 then causes the linkage gear 915 to rotate, which in turn causes the transmission gear set 914 to rotate. The transmission gear set 914 then causes the rotating shaft 913 to rotate. The rotating shaft 913, through the fourth bevel gear 412, drives the lower feed roller 904 to rotate. At this time, the fourth bevel gear 412 drives the third bevel gear 411 to drive the rotating rod 40. 6. Rotating rod 406 drives rotating sleeve 408 to rotate, rotating sleeve 408 drives second bevel gear 410 to rotate, second bevel gear 410 drives first bevel gear 409 to rotate, first bevel gear 409 drives upper feed roller 904 to rotate in opposite directions via first rotating shaft. The relative rotation of the upper and lower feed rollers 904 drives the metal sheet forward, so that the unpressed part of the metal sheet advances to the forming mold 8, waiting for the next press by stamping module 3. Furthermore, the advance of the metal sheet is different when facing finished products of different sizes. At this time, the movable cylinder 908 drives connecting rod 9 10. The connecting rod 910 drives the stroke rod 911 to move within the stroke groove 909. The stroke rod 911 drives the connecting seat 912 to move. The connecting seat 912 drives the linkage gear 915 and the drive gear 916 to move, causing the linkage gear 915 to move relative to each other and mesh with other gears in the gear set 914. This changes the transmission ratio between the connecting shaft and the rotating shaft 913, changes the rotation of the feed roller 904, and changes the amount of movement of the metal sheet driven by the feed roller 904. This allows for changes in the amount of metal sheet fed, making it suitable for different stamping requirements.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
