Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a positioning device for a stamping die of a stamping machine. Background Technique

[0002] A stamping die is a tool used for stamping processing, usually consisting of two parts: an upper die and a lower die. Stamping dies are usually used to apply high pressure on the surface of metal or other materials to change their shapes into the required shapes.

[0003] As disclosed in a positioning device for a stamping die of a stamping machine with the authorization announcement number CN220970543U, it has a base, and limit plates are slidably arranged left and right on both sides of the upper surface of the base. A clamping mechanism is slidably arranged front and back on one side of the limit plate. The clamping mechanism is of an L-shaped structure, and the L-shaped notch surface of the clamping mechanism and the surface of the limit plate close to the die are on the same horizontal plane; the clamping mechanism includes a first clamping plate and a second clamping plate. After adopting the above technical solution, the beneficial effect of the utility model is that: through the L-shaped structure setting of the clamping mechanism, an unclosed "mouth"-shaped limiting space can be formed between adjacent clamping mechanisms, so that the front and back sides of the die can be clamped on four sides.

[0004] Although the above patent can clamp the front and back sides of the die on four sides, when the die to be clamped is heavy, the die cannot be centered and positioned by the clamping mechanism. Therefore, although the above patent can conveniently fix the die, it is extremely laborious when positioning a relatively heavy die. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning device for a stamping die of a stamping machine to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A positioning device for a stamping die of a stamping machine, comprising

[0008] a base, a clamping table is fixedly installed at the top of the base, clamping mechanisms one are symmetrically arranged on both sides of the top of the clamping table, and clamping mechanisms two are symmetrically arranged on the other two sides of the clamping table;

[0009] a lifting groove, the lifting groove is opened in the middle of the clamping table, a rotating mechanism is movably installed inside the lifting groove, and a lifting mechanism is arranged below the base at the position of the rotating mechanism.

[0010] Preferably, the clamping mechanism one includes a fixing seat one, the fixing seat one is symmetrically arranged on both sides of the top of the clamping table, clamping cylinders one are arranged on the backs of the two fixing seats one, and clamping plates one are fixedly installed on the output shafts of the clamping cylinders one;

[0011] Preferably, the second clamping mechanism includes a second fixed seat symmetrically arranged at both ends of one side of the clamping table away from the two first fixed seats. Clamping cylinders II are arranged on the back surfaces of the two second fixed seats. The output shafts of the clamping cylinders II are fixedly installed with second clamping plates, and a number of guide rollers are movably installed on the inner sides of the front surfaces of the second clamping plates;

[0012] Preferably, the rotating mechanism includes a rotating table movably installed inside the lifting groove. A tray is arranged directly below the bottom end of the rotating table. A rotating cylinder is fixedly installed in the middle of the bottom end of the tray. The output shaft of the rotating cylinder passes through the tray and is fixedly connected to the rotating table. A number of supporting rollers are movably installed on the upper end of the rotating table;

[0013] Preferably, the rotating mechanism further includes a circular guide rail fixedly installed on the upper end surface of the tray. Slide seats are movably installed on both sides of the circular guide rail, and the two slide seats are fixedly connected to both sides of the bottom end of the tray;

[0014] Preferably, the lifting mechanism includes a bottom frame fixedly installed in the middle of the bottom end of the tray. A lifting cylinder is arranged below the inside of the base. The output shaft of the lifting cylinder is fixedly connected to the bottom frame. Supporting blocks are arranged at both ends inside the base, and the supporting blocks are located directly below both sides of the bottom end of the tray.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. For the stamping die positioning device of a stamping machine, through the combined use of the first clamping cylinder, the first clamping plate, the second clamping cylinder, the second clamping plate and the rotating table, when the tray descends, it drives the rotating table to retract into the lifting groove, then control the rotating cylinder to start. The rotating cylinder controls the rotating table to rotate 90°, until the supporting rollers are parallel to the first clamping plate and perpendicular to the second clamping plate. Then, the lifting cylinder is used to control the rotating table to lift and support under the die. Next, start the first clamping cylinder. When the first clamping cylinder controls the first clamping plate to push forward, when the first clamping plate pushes forward, the bottom end of the die moves backward through the guidance of the supporting rollers until the die is centered, thus achieving the purpose of facilitating centering positioning.

[0017] 2. For the stamping die positioning device of a stamping machine, through the combined use of the first clamping plate, the second clamping plate, the rotating table, the rotating cylinder, the supporting rollers and the lifting cylinder, the device can control the rotation of the rotating table through the rotating cylinder, and then control the supporting rollers to adjust the angle. When the supporting rollers are parallel to the second clamping plate, when the two second clamping plates clamp the die, the die can be supported and guided by the supporting rollers. When the supporting rollers are parallel to the first clamping plate, when the two first clamping plates clamp the die, the die is supported and guided by the supporting rollers again. In this way, during adjustment, if the die is relatively heavy, the supporting rollers can be used to save effort, making the movement of the die smoother. Description of the Drawings

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-4 shown, a technical solution provided by the present utility model:

[0025] A positioning device for a stamping die of a stamping machine, including a base 1, a clamping table 2 is fixedly installed at the top of the base 1, clamping mechanisms one are symmetrically arranged on both sides of the top of the clamping table 2, each clamping mechanism one includes a first fixing seat 4, the first fixing seats 4 are symmetrically arranged on both sides of the top of the clamping table 2, a first clamping cylinder 5 is arranged on the back of each of the two first fixing seats 4, a first clamping plate 6 is fixedly installed on the output shaft of the first clamping cylinder 5, clamping mechanisms two are symmetrically arranged on the other two sides of the clamping table 2, each clamping mechanism two includes a second fixing seat 7, the second fixing seats 7 are symmetrically arranged at both ends of one side of the clamping table 2 away from the two first fixing seats 4, a second clamping cylinder 8 is arranged on the back of each of the two second fixing seats 7, a second clamping plate 9 is fixedly installed on the output shaft of the second clamping cylinder 8, and a plurality of guide rollers 10 are movably installed on the inner side of the front surface of the second clamping plate 9;

[0026] In this embodiment, when fixing the mold, place the mold on the rotating table 11, then start the second clamping cylinder 8. The second clamping cylinder 8 controls the second clamping plate 9 to clamp on both sides of the mold. Then start the lifting cylinder 18. The lifting cylinder 18 controls the tray 12 to descend. When the tray 12 descends, it drives the rotating table 11 to retract into the lifting slot 3. Then control the rotating cylinder 13 to start. The rotating cylinder 13 controls the rotating table 11 to rotate 90°. Until the roller 14 is parallel to the first clamping plate 6 and perpendicular to the second clamping plate 9. Then control the rotating table 11 to lift and support under the mold through the lifting cylinder 18. Then start the first clamping cylinder 5. The first clamping cylinder 5 controls the first clamping plate 6 to push forward. When the first clamping plate 6 pushes forward, the bottom end of the mold moves backward through the guidance of the roller 14 until the mold is centered, so as to achieve the purpose of facilitating centering positioning.

[0027] As Figure 2 As shown, the lifting slot 3 is opened in the middle of the clamping table 2. A rotating mechanism is movably installed inside the lifting slot 3. The rotating mechanism includes a rotating table 11. The rotating table 11 is movably installed inside the lifting slot 3. A tray 12 is arranged directly below the bottom end of the rotating table 11. A rotating cylinder 13 is fixedly installed in the middle of the bottom end of the tray 12. The output shaft of the rotating cylinder 13 passes through the tray 12 and is fixedly connected to the rotating table 11. A plurality of rollers 14 are movably installed on the upper end of the rotating table 11. The rotating mechanism further includes a circular guide rail 15. The circular guide rail 15 is fixedly installed on the upper end surface of the tray 12. Two sliding seats 16 are movably installed on both sides of the circular guide rail 15. The two sliding seats 16 are fixedly connected to both sides of the bottom end of the tray 12;

[0028] In this embodiment, the device can control the rotation of the rotating table 11 through the rotating cylinder 13, and then control the roller 14 to adjust the angle. When the roller 14 is parallel to the second clamping plate 9, when the two second clamping plates 9 clamp the mold, the mold can be lifted and guided by the roller 14. When the roller 14 is parallel to the first clamping plate 6, when the two first clamping plates 6 clamp the mold, the mold is lifted and guided by the roller 14 again. In this way, when adjusting, if the mold is relatively heavy, the roller 14 can be used to save effort, making the mold move more smoothly.

[0029] As Figure 3 As shown, a lifting mechanism is arranged below the rotating mechanism on the base 1. The lifting mechanism includes a bottom frame 17. The bottom frame 17 is fixedly installed in the middle of the bottom end of the tray 12. A lifting cylinder 18 is arranged below the inside of the base 1. The output shaft of the lifting cylinder 18 is fixedly connected to the bottom frame 17. Support blocks 19 are arranged at both ends inside the base 1. The support blocks 19 are located directly below both sides of the bottom end of the tray 12;

[0030] In this embodiment, in order to ensure that the idler 14 does not contact the bottom of the mold when adjusting the angle of the idler 14, a lifting cylinder 18 is installed below the interior of the base 1 of this device. The lifting cylinder 18 can control the lifting of the rotating table 11, and thus control the lifting movement of the rotating table 11 below the mold.

[0031] Working principle: When fixing the mold, place the mold on the rotating table 11, then start the clamping cylinder II 8. The clamping cylinder II 8 controls the clamping plate II 9 to clamp on both sides of the mold. Then start the lifting cylinder 18. The lifting cylinder 18 controls the tray 12 to descend. When the tray 12 descends, it drives the rotating table 11 to retract into the lifting slot 3. Then control the rotation cylinder 13 to start. The rotation cylinder 13 controls the rotating table 11 to rotate 90°. Until the idler 14 is parallel to the clamping plate I 6 and perpendicular to the clamping plate II 9. Then, through the lifting cylinder 18, control the rotating table 11 to lift and support below the mold. Then start the clamping cylinder I 5. The clamping cylinder I 5 controls the clamping plate I 6 to push forward. When the clamping plate I 6 pushes forward, the bottom end of the mold moves backward after being guided by the idler 14 until the mold is centered.
