Description

Technical Field

[0001] The present invention relates to the technical field of continuous automatic stamping, and more specifically, to a continuous automatic stamping device and a stamping method. Background Art

[0002] In the stamping production process of the manufacturing industry, continuous automatic stamping devices are widely used due to their high production capacity. However, when the existing continuous automatic stamping devices perform continuous stamping operations on stamped parts, there are many problems that affect stability.

[0003] For example, most traditional stamping devices rely on manual or independent drive mechanisms to complete positioning and clamping, resulting in the stamped parts being prone to displacement due to vibration and external force interference during transmission, affecting the accuracy of the stamping position. At the same time, when the stamping device performs continuous stamping, there is a lack of an efficient mechanical linkage structure, making it difficult to achieve equidistant displacement and automatic circulation of the stamped parts, and frequent shutdown adjustments are required, resulting in low production efficiency. In addition, the die guiding and buffering mechanisms of existing devices are insufficient, and the impact force during the stamping process is likely to cause workpiece deformation or equipment wear, further reducing product quality and equipment life. Therefore, there is an urgent need for a continuous automatic stamping device and a stamping method to solve the above problems. Summary of the Invention

[0018] A continuous automatic stamping method is applied to a continuous automatic stamping device described in the above embodiment. The method includes the following steps:

[0019] S1: Place the stamping part on the conveying roller and move it to the positioning table. At this time, under the action of the second spring, the positioning box is clamped into the punching groove of the stamping part through the locking groove to complete the initial positioning;

[0020] S2: Start the hydraulic rod to drive the fixed plate and the punch head downward. The sliding column provides vertical guidance. The first guide column is inserted into the docking seat to compress the fourth spring and drive the plug column downward. The U-shaped plate, the vertical rod and the gear are engaged and the driven wheel drives the threaded screw to rotate, thereby causing the threaded sleeve to move horizontally. The sliding rod drives the clamping plate to clamp the stamping part. At the same time, the punch head and the stamping groove cooperate to complete the first stamping.

[0021] S3: After the stamping is completed, the fixed plate continues to move downward, the reinforcement plate drives the rotating seat to move, and at the same time, the roller at the end of the swing arm contacts the inclined surface of the ramp platform, pushing the swing arm to rotate around the rotating axis to compress the first spring, and the horizontal swing moves the stamping part to move one punching slot spacing. At the same time, the roller presses down the inclined plate, and the positioning box is lowered from the locking slot through the U-shaped rod and the sliding block, releasing the positioning restriction on the stamping part;

[0022] S4: When the rocker arm is separated from the ramp, the third spring and the second spring reset, and the positioning box is clamped into the next punching slot of the stamping part to achieve secondary positioning, while the hydraulic rod drives the part upward to reset. The fourth spring moves the docking seat upward, and the gear rotates in the opposite direction, thereby causing the clamping plate to descend and release the workpiece, completing a stamping cycle. Repeat steps S2-S4 to achieve continuous automatic stamping.

[0023] Beneficial effects of the present invention:

[0024] The present invention provides a continuous automatic stamping equipment and stamping method. Through the provided guide assembly and clamping assembly, the stamping part is moved to the positioning table through the conveyor roller, and then the hydraulic rod drives the fixed plate and the stamping head downward to cooperate with the stamping groove, thereby realizing the stamping work of the stamping part. During the downward movement of the stamping head, the sliding column provides vertical guidance for the stamping head, and the ball in the guide hole reduces the movement resistance of the first guide column to ensure the stamping accuracy. As the first guide column is continuously inserted, the first guide column will be inserted into the docking seat and compress the fourth spring. During this process, the plug column fixed at the bottom of the docking seat will also descend together. The downward movement of the plug column can drive the U-shaped plate to push the vertical rod to move vertically downward. At this time, the tooth groove opened on the outer wall of the vertical rod and the tooth groove are aligned with the tooth groove of the vertical rod. The gears are engaged, so that the gears can rotate. During the rotation of the gears, the first rotating column fixed on the outer wall thereof can be driven to rotate together. When the first rotating column rotates, it can drive the driving wheel, the transmission belt and the driven wheel to rotate, and then the threaded screw is driven to rotate by the driven wheel to make the threaded sleeve move laterally. During the lateral movement of the threaded sleeve, the clamping plate is driven horizontally by the sliding rod until the stamping part is clamped, ensuring that the stamping part can always remain stable during the stamping work and avoiding skewness during the stamping process. At the same time, the bottom of the threaded sleeve is also fixedly connected to the push plate by a bent column. Therefore, during the horizontal movement of the threaded sleeve, the push plate is pushed by the bent column to push the stamped workpiece out of the discharge chute.

[0025] The present invention provides a continuous automatic stamping equipment and stamping method. Through the provided displacement assembly and positioning assembly, when the fixed plate descends during the stamping process, the reinforcing plate drives the rotating seat to move. At this time, the roller at the end of the rocker arm contacts the inclined surface of the ramp platform, and under the action of the slope, the rocker arm is pushed to rotate around the rotating shaft and compress the first spring, so that the rocker arm swings horizontally to move the stamping part a punching groove spacing, thereby realizing the automatic continuous stamping of the stamping part. When the roller applies downward pressure to the ramp platform, the pressure is fully applied to the inclined plate. When the inclined plate is subjected to the downward pressure, it moves toward the inside of the ramp platform. At the same time, the U-shaped rod connected to the bottom thereof is rotated to move obliquely downward. Since the sliding block fixed at the other end of the U-shaped rod moves along the The first through slot moves, thereby offsetting the horizontal pressure of the U-shaped rod. At this time, the U-shaped rod only has vertical pressure, which can drive the positioning box to descend together. When the positioning box descends, it disengages from the locking slot, thereby releasing the blocking effect on the stamping part, ensuring that the stamping part can move stably horizontally. When the rocker arm swings horizontally to move the stamping part a slot spacing, the rocker arm is separated from the ramp platform. At this time, there is no downward pressure on the inclined plate, and the positioning box can be reset and connected to another slot of the stamping part through the action of the second spring, realizing secondary fixation of the stamping part, ensuring that the stamping part will not be offset or skewed during stamping work, thereby improving the stamping quality of the stamping part.

[0026] The present invention provides a continuous automatic stamping equipment and stamping method, which converts the linear motion of the hydraulic rod into gear transmission and rocker arm swing through power coupling, uses an elastic buffer structure to alleviate impact, and realizes precise positioning, stable clamping and equidistant displacement of stamping parts through mechanical closed-loop linkage, ensuring the high efficiency and stability of continuous stamping.

The tooth groove on the outer wall of the vertical rod 26 meshes with the gear 20, converting the vertical movement into the rotational movement of the gear 20, which can provide power for subsequent components.

[0046] Further, a U-shaped plate 25 is fixedly connected to the outer wall of one side of the second support plate 50. A vertical rod 26 is fixedly connected to the bottom of the U-shaped plate 25. A tooth groove is formed in the outer wall of one side of the vertical rod 26. A gear 20 is arranged on one side of the vertical rod 26. The gear 20 meshes with the tooth groove. A first rotating column 21 is fixedly connected to the inner wall of the circumference of the gear 20.

A clamping plate 13 is fixedly connected to the outer wall of the top of the slide bar 46. The clamping plate 13 is located inside the groove 14. Under the action of the slope of the slope table 10, the swing rod 9003 rotates around the rotating shaft 9007 and compresses the first spring 9009 to realize horizontal swing. At the same time, the stamping part 3 is pushed to move a punching groove spacing, and the stop rod 9010 limits the swing angle of the swing rod 9003 to ensure the accurate displacement distance of the stamping part 3.

[0048] Further, a discharge groove 7 is formed on one side of the stamping table 4. A first support plate 6 is fixedly connected to the outer wall on one side of the stamping table 4.

At this time, the roller 9004 at the end of the swing rod 9003 contacts the inclined surface of the slope table 10. Under the action of the slope, the swing rod 9003 is pushed to rotate around the rotating shaft 9007 and compress the first spring 9009, so that the swing rod 9003 swings horizontally to move the stamping part 3 by a punching groove pitch, realizing the automatic continuous stamping work of the stamping part 3.

[0050] Further, a second through groove 41 is formed in the top of the ramp table 10. An inclined plate 42 flush with the top of the ramp table 10 is arranged inside the second through groove 41. A second guiding column 39 is fixedly connected to the outer wall of one side of the inclined plate 42. A positioning plate 38 is fixedly connected inside the ramp table 10.

The positioning box 31 passes through the inside of the locking groove 44. A first through groove 32 is formed in the bottom inner wall of the positioning box 31. The sliding block 33 passes through the inside of the first through groove 32. A limiting ring plate 34 is fixedly connected to the circumferential outer wall of the sliding block 33. The bottom outer wall of the limiting ring plate 34 is in contact with the bottom inner wall of the positioning box 31. When the roller 9004 presses down the inclined plate 42 at the top of the ramp table 10, the inclined plate 42 compresses the third spring 40 through the second guiding column 39 and moves towards the inside of the ramp table 10, driving the U-shaped rod 35 to move obliquely downwards. The sliding block 33 at one end of the U-shaped rod 35 slides along the first through groove 32 of the positioning box 31. The limiting ring plate 34 cancels the horizontal pressure of the U-shaped rod 35 and only transmits the vertical pressure, enabling the positioning box 31 to descend from the locking groove 44 against the elastic force of the second spring 37, releasing the positioning of the stamping part 3. A stop rod 9010 is fixedly connected to the bottom outer wall of the reinforcing plate 9001. One side outer wall of the swing rod 9003 is in contact with one side outer wall of the stop rod 9010. After the swing rod 9003 is separated from the ramp table 10, the third spring 40 pushes the inclined plate 42 to reset. At the same time, the second spring 37 jacks up the positioning box 31 upwards, causing it to be stuck into the next punching groove of the stamping part 3, realizing the secondary fixation of the stamping part 3, ensuring the stable position of the stamping part 3 during the stamping process, and avoiding deviation and skew.

[0051] A continuous automatic stamping method is applied to a continuous automatic stamping device in the above embodiment. The method includes the following steps:

[0052] Step 1: Place the stamping part 3 on the conveying roller and move it to the positioning table 11. At this time, under the action of the second spring 37, the positioning box 31 is stuck into the punching groove of the stamping part 3 through the locking groove 44 to complete the initial positioning;

[0053] Step 2: Start the hydraulic rod 2 to drive the fixed plate 19 and the stamping head 18 to move downward. The sliding column 5 provides vertical guidance. The first guide post 17 is inserted into the docking seat 47 to compress the fourth spring 49 and drive the insertion post 48 to move downward. It is meshed and transmitted with the gear 20 through the U-shaped plate 25 and the vertical rod 26, so that the driven wheel 22 drives the threaded lead screw 24 to rotate, and then the threaded sleeve 45 moves horizontally. The clamping plate 13 is driven by the slide bar 46 to clamp the stamping part 3. At the same time, the stamping head 18 and the stamping groove 12 cooperate to complete the first stamping;

[0054] Step 3: After the stamping is completed, the fixed plate 19 continues to move downward. The reinforcement plate 9001 drives the rotating seat 9002 to move. At the same time, the roller 9004 at the end of the swing rod 9003 contacts the inclined surface of the ramp 10, pushing the swing rod 9003 to rotate around the rotating shaft 9007 and compress the first spring 9009. It swings horizontally to move the stamping part 3 by a punching groove spacing. At the same time, the roller 9004 presses down the inclined plate 42, and through the U-shaped rod 35 and the sliding block 33, the positioning box 31 descends from the locking groove 44 to release the positioning restriction on the stamping part 3;

[0055] Step 4: When the swing rod 9003 is separated from the ramp 10, the third spring 40 and the second spring 37 are reset. The positioning box 31 is clamped into the next punching groove of the stamping part 3 to achieve secondary positioning. The hydraulic rod 2 drives the components to move upward and reset. The fourth spring 49 moves the docking seat 47 upward. At the same time, the gear 20 rotates in the reverse direction, and then the clamping plate 13 descends to release the workpiece, completing one stamping cycle. Repeat steps 2 - 4 to achieve continuous automatic stamping.

[0056] In summary, by means of the above technical solutions of the present invention, during use, the staff places the stamping part 3 on the conveying rollers. The stamping part 3 moves to the positioning table 11 through the conveying rollers. Subsequently, the hydraulic rod 2 drives the fixed plate 19 and the stamping head 18 to move downward to cooperate with the stamping groove 12, thereby realizing the stamping work on the stamping part 3. During the downward movement of the stamping head 18, the sliding column 5 provides vertical guidance for the stamping head 18, and the balls 15 in the guiding hole 16 reduce the moving resistance of the first guiding column 17 to ensure the stamping accuracy. As the first guiding column 17 continues to be inserted, the first guiding column 17 will be inserted into the docking seat 47 and compress the fourth spring 49. During this process, the insertion column 48 fixed to the bottom of the docking seat 47 will also descend together. The downward movement of the insertion column 48 can drive the U-shaped plate 25 to push the vertical rod 26 to move vertically downward. At this time, the tooth groove opened on the outer wall of the vertical rod 26 meshes with the gear 20, so that the gear 20 can rotate. During the rotation of the gear 20, it can drive the first rotating column 21 fixed to its outer wall to rotate together. When the first rotating column 21 rotates, it can drive the driving wheel 30, the transmission belt 23 and the driven wheel 22 to rotate. Subsequently, the driven wheel 22 drives the threaded lead screw 24 to rotate, causing the threaded sleeve 45 to move horizontally. During the horizontal movement of the threaded sleeve 45, the clamping plate 13 is driven by the sliding rod 46 to move horizontally until the stamping part 3 is clamped, ensuring that the stamping part 3 can always remain stable during the stamping work and avoiding situations such as skewing during the stamping process. At the same time, the bottom of the threaded sleeve 45 is fixedly connected to the pushing plate 28 through the bent column 27. Therefore, during the horizontal movement of the threaded sleeve 45, the pushing plate 28 can be pushed through the bent column 27 to push the stamped workpiece out of the discharging groove 7;

[0057] During the stamping process, when the fixed plate 19 moves downward, the reinforcing plate 9001 drives the rotating seat 9002 to move. At this time, the roller 9004 at the end of the rocker arm 9003 contacts the inclined surface of the ramp platform 10. Under the action of the slope, the rocker arm 9003 is pushed to rotate around the rotating shaft 9007 and compress the first spring 9009, so that the rocker arm 9003 swings horizontally to move the stamping part 3 by a slot spacing, thereby realizing the automatic continuous stamping of the stamping part 3. When the roller 9004 applies downward pressure to the ramp platform 10, all the pressure will be applied to the inclined plate 42. When the inclined plate 42 is When the downward pressure is applied, the U-shaped rod 35 will move toward the inside of the ramp 10. At the same time, the U-shaped rod 35 connected to the bottom thereof will move obliquely downward. Since the sliding block 33 fixed at the other end of the U-shaped rod 35 moves along the first through slot 32, the horizontal pressure of the U-shaped rod 35 can be offset. At this time, the U-shaped rod 35 only has vertical pressure, which can drive the positioning box 31 to descend together. When the positioning box 31 descends, it disengages from the locking slot 44, thereby releasing the blocking effect on the stamping part 3, ensuring that the stamping part 3 can move stably horizontally. When the swing arm 9003 swings horizontally When the stamping part 3 is moved by a slot spacing, the rocker arm 9003 is separated from the ramp platform 10. At this time, there is no downward pressure on the inclined plate 42, and the positioning box 31 can be reset and connected to another slot of the stamping part 3 through the action of the second spring 37, realizing the secondary fixation of the stamping part 3, ensuring that the stamping part 3 will not be offset or skewed during the stamping work, and improving the stamping quality of the stamping part 3. When the stamping is completed, the hydraulic rod 2 drives the component to reset upward. At the same time, the fourth spring 49 moves the docking seat 47 upward, and the gear 2 0 reverse rotation allows the clamping plate 13 to descend and release the workpiece, and the rocker arm 9003 is reset under the action of the first spring 9009. When the roller 9004 leaves the ramp 10, the stamping part 3 has moved to the next station, and the positioning, clamping, stamping, and shifting processes are repeated to achieve continuous production. The entire process converts the linear motion of the hydraulic rod 2 into the transmission of the gear 20 and the swing of the rocker arm 9003 through power coupling, and uses the elastic buffer structure to alleviate the impact. The mechanical closed-loop linkage realizes the precise positioning, stable clamping and equidistant shifting of the stamping part 3, ensuring the high efficiency and stability of continuous stamping.
