Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing die locking equipment, in particular to a locking device suitable for wire drawing dies. Background Art

[0002] Wire drawing dies are one of the important components in the current production of metal wires. The metal is driven by external force to pass through the corresponding die, and the cross-section of the metal is compressed by the extrusion of the die, so that the metal is produced into the required size. It is also one of the main means of metal wire production. In order to ensure smooth production, the die needs to be locked and fixed.

[0003] The current mold locking device basically clamps the mold, sets up the fixture into an arc structure corresponding to the mold, and then drives the fixture to clamp and position the mold through a telescopic cylinder. This method requires the use of multiple telescopic cylinders, which is costly and can only clamp the two sides of the mold without other limiting means. The mold has stability issues, so a locking device is set up for this purpose. Utility Model Content

[0005] As a preferred technical solution of the utility model, four telescopic grooves are evenly opened in the vertical plate, each of the telescopic grooves is telescopically interspersed with a threaded column, and two limiting plates are fixedly connected to the side wall at one end of each telescopic groove, one end of the limiting plate is inserted into one end of the threaded column, and a bevel gear is rotatably connected to the inner wall of the telescopic groove, a threaded groove is opened in the middle of the bevel gear, and the bevel gear is threadedly sleeved on the threaded column through the threaded groove, one end of the threaded column extends into the inner groove and is fixedly connected with a connecting plate, and both ends of the connecting plate away from each other are rotatably connected with a docking plate, and one end of the docking plate away from the connecting plate is rotatably connected to the corresponding side wall of the clamping plate, and the docking plate is a telescopic structure.

[0007] The utility model has the following advantages: positioning grooves are provided on the inner walls of the four pairs of splints, and the mold is placed in the positioning grooves. The mold can be limited by the side of the positioning grooves to ensure the stability of the mold placement. At the same time, a layer of anti-skid pad is fixed on the inner wall of the positioning groove, which can increase the friction between the positioning groove and the mold while avoiding wear on the mold. In addition, because there are four pairs of splints, the mold can be locked and positioned in multiple directions, fully ensuring the stability of the mold after connection, and avoiding negative effects such as shaking of the mold during the production process.

DETAILED DESCRIPTION

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] Please refer to Figure 1-4 The utility model is a locking device for a wire drawing die, comprising a vertical plate 1, an inner groove 4 is provided through the middle of the vertical plate 1, a rotating groove 2 is provided on the side wall of the vertical plate 1 close to the inner groove 4, a rotating ring 3 is rotatably connected in the rotating groove 2, four pairs of clamping plates 5 are set in the inner groove 4, a positioning groove 6 is provided in the middle of the inner wall of each clamping plate 5, an anti-slip pad is fixedly connected to the inner wall of the positioning groove 6, and a rotating shaft 13 is rotatably connected to the adjacent ends of each pair of clamping plates 5;

[0016] Four telescopic grooves 7 are evenly opened in the vertical plate 1, and each telescopic groove 7 is telescopically interspersed with a threaded column 9, and two limiting plates 8 are fixedly connected to the side wall at one end of each telescopic groove 7, and one end of the limiting plate 8 is inserted in one end of the threaded column 9. A bevel gear 10 is rotatably connected to the inner wall of the telescopic groove 7, and a threaded groove is opened in the middle of the bevel gear 10. The bevel gear 10 is threadedly sleeved on the threaded column 9 through the threaded groove. One end of the threaded column 9 extends into the inner groove 4 and is fixedly connected with a connecting plate 11. Both ends of the connecting plate 11 away from each other are rotatably connected with a docking plate 12, and the end of the docking plate 12 away from the connecting plate 11 is rotatably connected to the corresponding side wall of the clamping plate 5, and the docking plate 12 is a telescopic structure.

[0017] The preferred technical effect of this scheme is that the rotating ring 3 drives the four pairs of clamps 5 to move, and the mold is pre-placed in the positioning groove 6 opened on the inner wall of the clamp 5. As the inner groove 4 shrinks and approaches the clamp 5, the mold can be locked and positioned. At the same time, the positioning groove 6 can ensure that the mold is still in a vertical upright state after being locked, avoiding the problem of tilting. At the same time, because the four pairs of clamps 5 move synchronously, it can be ensured that the mold is in the middle position after locking, eliminating the problem of production being unable to proceed smoothly due to the deviation of the center point of the mold.

[0018] The swivel 3 and the rotating groove 2 are both annular structures. One end of the swivel 3 extends into the telescopic groove 7 through the rotating groove 2. The end of the swivel 3 located in the telescopic groove 7 is fixedly connected with an annular driving gear ring 16. The driving gear ring 16 is meshed and connected with the bevel gear 10. Anti-retreat grooves 14 are provided on the side walls on both sides of the rotating groove 2, and the two anti-retreat grooves 14 are staggered with each other. A linkage plate 15 is rotatably connected in each anti-retreat groove 14, and the linkage plate 15 is fixedly connected to the side wall of the swivel 3 through one end thereof.

[0019] The preferred technical effect of this solution is that the rotating ring 3 can simultaneously drive the four bevel gears 10 to rotate via a meshing connection relationship. Through the threaded connection relationship, the threaded column 9 can be driven to extend and retract as the bevel gear 10 rotates. Through the transmission relationship, the corresponding splint 5 is finally driven to move via the connecting plate 11 and the docking plate 12. Therefore, the purpose of achieving synchronous movement of the four splints 5 by rotating a rotating ring 3 is achieved, effectively saving the traditional driving cost, and the operation is simple and convenient.

[0020] Specifically, when the utility model is used, the mold is placed in the positioning groove 6. Because the size specifications of the molds are different, each pair of clamps 5 is set up in a rotatable relationship through the rotating shaft 13. As the clamps 5 are tightened, the mold is clamped, and the force generated by the clamping will also act on the corresponding clamps 5. The corresponding clamps 5 are subjected to force and rotate along the rotating shaft 13 to perform adaptive adjustment, ensuring that the clamps 5 can fit closely with the outer walls of different molds, thereby improving the application flexibility and practicality of the equipment. At the same time, in order to ensure that the clamps 5 can be adjusted smoothly and a stable extrusion force can be applied to the clamps 5, the retractable docking plate 12 is used. The clamping plate 5 is connected with the connecting plate 11. When the clamping plate 5 rotates, the docking plate 12 will also be driven to move. Because the docking plate 12, the connecting plate 11 and the clamping plate 5 are in a rotational relationship, when the clamping plate 5 is adjusted to a suitable position, as the threaded column 9 drives the connecting plate 11 to gradually approach the clamping plate 5, the docking plate 12 will also gradually shrink. When the docking plate 12 shrinks to the limit, the clamping plate 5 will be driven to clamp the mold. In order to ensure the smooth operation of the swivel 3, an anti-retreat groove 14 and a linkage plate 15 rotating in the anti-retreat groove 14 are set to limit the swivel 3 so that the swivel 3 can drive the driving gear ring 16 to rotate stably.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0022] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
