Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to workpiece stamping production equipment. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet metal to deformation force in the mold and deform it, so as to obtain product parts of a certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping. Therefore, in order to improve the processing effect of stamping, it is inevitable to improve the above three elements. For example, the patent document with application number 202022941356.9 proposes "an automated stamping equipment forming mold with a buffer mechanism, comprising a lower pad, an upper pad and an upper die seat, the top of the lower pad is fixed with a lower die seat, the surface of the lower die seat is fixed with a first positioning column, a second positioning column and a lower die, A guide column is fixed between the upper pad and the lower pad, the upper mold seat is movably connected to the outer wall of the guide column, and a first positioning seat, a second positioning seat and an upper mold are fixed to the bottom of the upper mold seat, the first positioning seat corresponds to the first positioning column, the second positioning seat corresponds to the second positioning column, and a first buffer mechanism is arranged between the upper pad and the upper mold seat. After use, "the first buffer spring is compressed by a retaining ring for initial buffering, and the second buffer spring is compressed by a pressure ring for further buffering. The combined buffering of the first buffer spring and the second buffer spring protects the upper mold when the mold is opened, thereby preventing the upper mold from being unprotected due to lack of a buffer mechanism, thereby increasing the service life of the upper mold."

[0003] However, in reality, the upper limit of the effect of relying solely on a single spring structure for cushioning is too low, and as the use time increases, the fatigue of the spring structure gradually increases, and the cushioning effect gradually decreases accordingly. Secondly, the current stamping processing equipment is mostly independent operation, lacking production line mode operation design, and the processing efficiency is not easy to improve. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a workpiece stamping production device, which solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a workpiece stamping production equipment, including a roller heating furnace, a loading robot, a stamping equipment, a unloading robot, a servo loading platform, a basket loading robot ground rail, a basket loading robot slidably installed on the top of the basket loading robot ground rail, the basket loading robot is transmission-connected with a ten-axis flexible gripper, the loading robot is located between the roller heating furnace and the stamping equipment, the unloading robot is located between the stamping equipment and the servo loading platform, the basket loading robot ground rail is located outside one side of the servo loading platform and is aligned parallel to the servo loading platform, the stamping equipment includes a support table, a stamping mechanism, an upper die, and a lower die, the upper die and the lower die are respectively transmission-connected with the stamping output end of the stamping mechanism and are sleeved on the inner side of the bottom of the stamping mechanism, and the upper die is aligned with the lower die;

[0006] A hollow buffer box is installed on the top of the lower mold, and an elastic component, a friction sleeve and a damping ring are installed inside the hollow buffer box. The friction sleeve is installed between the elastic component and the damping ring, and the side walls on both sides of the hollow buffer box are equipped with friction rollers that can fit and contact the surface of the friction sleeve.

[0007] Preferably, a threaded hole is provided at the top of the upper mold, and a clearance hole aligned with the threaded hole is provided at the bottom structure of the hollow buffer box. The bottom of the hollow buffer box and the top of the upper mold are detachably installed by means of screws penetrating the clearance hole and then being threadedly connected in the threaded hole.

[0008] The elastic component includes a main buffer spring, the ends of the main buffer spring are fixedly connected with a combined cover plate, and the interior of the combined cover plate is magnetically connected with magnet blocks, and the two magnet blocks are respectively fixedly connected to the inner wall of the bottom of the hollow buffer box and the bottom surface of the friction sleeve block.

[0009] Preferably, the number of the friction rollers is not less than two and they are evenly distributed on the side walls on both sides of the hollow buffer box, and the two adjacent friction rollers can actively clamp the friction sleeve block. In the process of synchronously buffering the ups and downs of the friction sleeve block and the elastic component, the friction rollers cooperate with the friction sleeve block to dissipate friction energy.

[0010] Preferably, a step groove and a threaded hole are provided in the side wall of one side of the hollow buffer box, the threaded hole penetrates the side wall on one side of the step groove, a movable cover plate is clamped in the step groove, and the movable cover plate and the threaded hole are installed by screws, thereby facilitating the maintenance and replacement of the structure arranged inside the hollow buffer box.

[0011] Preferably, a synchronous transmission rod and a battery module are sleeved inside the friction sleeve block. A pressure sensor is installed on the inner wall of the top of the hollow buffer box. The synchronous transmission rod is composed of an inverted T-shaped rod and a buffer spring. One end of the inverted T-shaped rod penetrates through the top structure of the friction sleeve block and aligns with the pressure sensor. The two ends of the buffer spring are respectively fixedly connected to the surface of one end of the inverted T-shaped rod and the inner wall of the top of the friction sleeve block. Thus, the synchronous transmission rod and the pressure sensor are in relative contact with the buffer undulation of the elastic component, and then multiple groups of pressure data are output. Subsequently, the fatigue degree of the main buffer spring in the elastic component can be known through the change of the pressure data, so as to replace it in time.

[0012] Preferably, one end of the inverted T-shaped rod is a hemispherical structure to avoid scratching the pressure sensor. Moreover, during the deformation and buffering process of the elastic component, the inverted T-shaped rod and the damping ring can respectively press against and contact the pressure sensor and the inner wall of the top of the hollow buffer box.

Then, the pressure sensor outputs multiple groups of pressure data. Subsequently, the fatigue degree of the main buffer spring in the elastic component can be known through the change of the pressure data, so as to replace it in time later to maintain the buffer effect.

[0024] Embodiment 1

The upper die 10 and the lower die 11 are respectively drivingly connected to the stamping output end of the stamping mechanism 9 and sleeved inside the bottom of the stamping mechanism 9, and the upper die 10 and the lower die 11 are aligned;

[0026] A hollow buffer box 12 is installed on the top of the lower mold 11, and an elastic component 13, a friction sleeve block 14, and a damping ring 16 are installed inside the hollow buffer box 12. The friction sleeve block 14 is installed between the elastic component 13 and the damping ring 16. The elastic component 13 includes a main buffer spring 131, and the ends of both ends of the main buffer spring 131 are fixedly connected to a combined cover plate 132, and the inside of the combined cover plate 132 is magnetically connected to a magnet block 133. The two magnet blocks 133 are fixedly connected to the inner wall of the bottom of the hollow buffer box 12 and the bottom surface of the friction sleeve block 14 respectively.

[0027] The side walls on both sides of the hollow buffer box 12 are both equipped with friction rollers 15 that can fit and contact the surface of the friction sleeve 14. The number of friction rollers 15 is not less than two and is evenly distributed on the side walls on both sides of the hollow buffer box 12. The two adjacent friction rollers 15 can be in a movable clamping state for the friction sleeve 14. In the process of synchronously buffering the ups and downs of the friction sleeve 14 and the elastic component 13, the friction rollers 15 cooperate with the friction sleeve 14 to dissipate friction energy;

[0028] A threaded hole is provided at the top of the upper mold 10, and a clearance hole aligned with the threaded hole is provided at the bottom structure of the hollow buffer box 12. The bottom of the hollow buffer box 12 and the top of the upper mold 10 are detachably installed by screws passing through the clearance hole and then being threaded in the threaded hole.

[0029] Working principle: When in use, the blank is first fed into the roller heating furnace 1 for heating, and then the loading robot 2 automatically places the heated sheet blank between the upper die 10 and the lower die 11, and the stamping mechanism 9 drives the upper die 10 and the lower die 11 to perform stamping processing, then the unloading robot 4 takes it out and automatically places it in the loading space of the servo loading platform 5, and finally, the basket loading robot 7 drives the ten-axis flexible gripper 8 to automatically grab and basket the stamped workpiece in the loading space under the support and transmission of the basket loading robot ground rail 6, thereby realizing the assembly line processing of stamping from loading, stamping, unloading and moving basket loading;

[0030] During the stamping process of the upper die 10 and the lower die 11, the stamping vibration of the upper die 10 is buffered by the elastic deformation of the main buffer spring 131 inside the elastic component 13. At the same time, the main buffer spring 131 presses the friction sleeve 14 and the damping ring 16 to move up and down. The damping ring 16 contacts the top inner wall of the hollow buffer box 12 for damping and buffering. The friction sleeve 14 reciprocates with multiple friction rollers 15 to dissipate energy through friction, thereby fully reducing the vibration damage to the upper die 10.

[0033] A hollow buffer box 12 is installed on the top of the lower mold 11, and an elastic component 13, a friction sleeve block 14, and a damping ring 16 are installed inside the hollow buffer box 12. The friction sleeve block 14 is installed between the elastic component 13 and the damping ring 16. The elastic component 13 includes a main buffer spring 131, and the ends of both ends of the main buffer spring 131 are fixedly connected to a combined cover plate 132, and the inside of the combined cover plate 132 is magnetically connected to a magnet block 133. The two magnet blocks 133 are fixedly connected to the inner wall of the bottom of the hollow buffer box 12 and the bottom surface of the friction sleeve block 14 respectively.

[0034] The side walls on both sides of the hollow buffer box 12 are both equipped with friction rollers 15 that can fit and contact the surface of the friction sleeve 14. The number of friction rollers 15 is not less than two and is evenly distributed on the side walls on both sides of the hollow buffer box 12. The two adjacent friction rollers 15 can be in a movable clamping state for the friction sleeve 14. In the process of synchronously buffering the ups and downs of the friction sleeve 14 and the elastic component 13, the friction rollers 15 cooperate with the friction sleeve 14 to dissipate friction energy;

[0035] A threaded hole is provided at the top of the upper mold 10, and a clearance hole aligned with the threaded hole is provided at the bottom structure of the hollow buffer box 12. The bottom of the hollow buffer box 12 and the top of the upper mold 10 are installed by screws penetrating the clearance hole and then threadedly connected in the threaded hole for detachable threading.

[0036] A step groove and a threaded hole are provided in the side wall of one side of the hollow buffer box 12. The threaded hole penetrates the side wall of one side of the step groove. A movable cover plate 19 is clamped in the step groove. The movable cover plate 19 and the threaded hole are installed by screws, thereby facilitating the maintenance and replacement of the structure set inside the hollow buffer box 12.

[0037] Inside the friction sleeve block 14, a synchronous transmission rod 17 and a battery module are sleeved. A pressure sensor 18 is installed on the inner wall of the top of the hollow buffer box 12. The synchronous transmission rod 17 is composed of an inverted T-shaped rod and a buffer spring. One end of the inverted T-shaped rod penetrates through the top structure of the friction sleeve block 14 and aligns with the pressure sensor 18. The two ends of the buffer spring are respectively fixedly connected to the surface of one end of the inverted T-shaped rod and the inner wall of the top of the friction sleeve block 14. Thus, the synchronous transmission rod 17 and the pressure sensor 18 are in relative contact with the buffer undulation of the elastic component 13, and then output multiple groups of pressure data. Subsequently, the fatigue degree of the main buffer spring 131 in the elastic component 13 can be known through the change of the pressure data, so as to replace it in time. One end of the inverted T-shaped rod is a hemispherical structure to avoid scratching the pressure sensor 18. Moreover, during the deformation and buffering process of the elastic component 13, the inverted T-shaped rod and the damping ring 16 can respectively press against the pressure sensor 18 and the inner wall of the top of the hollow buffer box 12.

[0038] Working principle: During use, the blank is first sent into the roller heating furnace 1 for heating, and then the heated sheet blank is automatically placed between the upper die 10 and the lower die 11 by the loading robot 2. The upper die 10 and the lower die 11 are driven by the stamping mechanism 9 for stamping processing. Then, it is taken out by the unloading robot 4 and automatically placed in the loading space of the servo loading platform 5. Finally, the basket loading robot 7 drives the ten-axis flexible gripper 8 to automatically grab and load the stamped workpieces in the loading space under the support and drive of the basket loading robot track 6, thus realizing the streamlined processing of stamping from loading, stamping, unloading to moving and loading into the basket.

[0039] During the stamping process of the upper die 10 and the lower die 11, the stamping vibration of the upper die 10 is elastically deformed and buffered by the main buffer spring 131 inside the elastic component 13. At the same time, it presses the friction sleeve block 14 and the damping ring 16 to move up and down. The damping ring 16 contacts the inner wall of the top of the hollow buffer box 12 for damping buffering, and the friction sleeve block 14 reciprocally contacts with multiple friction rollers 15 for friction energy dissipation, fully reducing the vibration damage suffered by the upper die 10.

[0040] During the long-term use of the elastic component 13, the synchronous transmission rod 17 synchronously presses the pressure sensor 18 with the buffer undulation of the elastic component 13 and the friction sleeve block 14. Then, the pressure sensor 18 outputs multiple groups of pressure data. Subsequently, the fatigue degree of the main buffer spring 131 in the elastic component 13 can be known through the change of the pressure data. When the elastic component 13 needs to be replaced, remove the screws between the movable cover plate 19 and the hollow buffer box 12, take out the main buffer spring 131 and the combined cover plate 132, replace the new main buffer spring 131 and the combined cover plate 132, and then reset and lock the movable cover plate 19.
