Description

Technical Field

[0001] The utility model relates to the technical field of a wire drawing die fixing tool, in particular to a fixing fixture for a wire drawing die. Background Art

[0002] Wire drawing dies are one of the important tools for producing metal into wire. The metal is passed through the die by external force, and the cross-section of the metal can be changed under the extrusion of the die. In this way, the metal can be turned into wire. In order to ensure smooth production, the mold itself needs to be fixed.

[0003] During production, the wire drawing die needs to be fixed at a specified position. The current fixing method is basically to clamp the two sides of the die through a splint. Due to the limited fixing method, it is easy to cause the stability of the die after fixation to be poor. The poor stability during the production process will directly lead to unqualified quality of the produced metal wire. For this purpose, a fixing fixture is set up. Utility Model Content

DETAILED DESCRIPTION

[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1-3 The utility model discloses a fixing fixture for a wire drawing die, comprising a frame 1, a bottom side wall of the frame 1 is fixedly connected with a bottom plate 2, two follower plates 3 are arranged above the bottom plate 2, a bidirectional screw 5 is rotatably connected to the inner wall of the frame 1 and close to the bottom plate 2, the two follower plates 3 are threadedly connected to the two ends of the bidirectional screw 5, a lifting plate 8 is arranged above the follower plate 3, the bottom of the lifting plate 8 and close to the edges of both ends are rotatably connected with telescopic plates 9, a pressing plate 10 is arranged below the lifting plate 8, a rotating shaft 11 is rotatably connected in the middle of the pressing plate 10, and the output ends of the two telescopic plates 9 are rotatably connected to the top of the pressing plate 10 and close to the edges of both ends;

[0014] The top side wall of the lifting plate 8 is rotatably connected with a lifting screw 12, one end of the lifting screw 12 is inserted and rotatably connected to the middle of the top side wall of the frame 1, the frame 1 is detachably connected with a motor 13 by a screw, the output end of the motor 13 is fixedly connected with a driving gear 16, and the driving gear 16 is meshed with a rack 18, the middle of the top side wall of the frame 1 is rotatably connected with a driven gear 17, the driven gear 17 is threadedly sleeved and connected to the lifting screw 12, and the rack 18 is meshed with the driven gear 17 by starting one end, the top of the frame 1 and near the two corners are fixedly connected with a reinforcement plate 7, the top of the frame 1 and near the middle position of the bottom side wall are fixedly connected with two limit rods 14, and the bottom ends of the limit rods 14 are telescopically sleeved in the two ends of the lifting plate 8.

[0015] The technical effect of this solution is that the mold is first placed above the two follower plates 3. The support pad 4 fixed on the top side wall of the follower plate 3 can ensure the stability of the mold placement and prevent the mold from falling from the follower plate 3. Then the pressing plate 10 can be driven to descend synchronously by the lifting screw 12. As the pressing plate 10 descends, the top side wall of the mold can be pressed. The three-claw clamping and fixing function can be realized through the cooperation of the pressing plate 10 and the two follower plates 3, which prevents the mold from shaking during the production process and prevents the quality of the produced metal wire from being affected by the shaking of the mold.

[0016] The bottom side walls of the two follower plates 3 are rotatably connected with balls 15 near both ends, the top side walls of the follower plates 3 are rotatably connected with support pads 4, the support pads 4 are arc-shaped structures, and the frame 1 is rotatably connected with a knob 6 near the bottom edge, one end of the knob 6 passes through the side wall of the frame 1 and is fixedly connected to one end of the bidirectional screw 5.

[0017] The technical effect of this solution is that, in order to improve the flexibility of equipment application, the bidirectional screw 5 is threadedly connected to the two follower plates 3, and the bidirectional screw 5 is driven to rotate by the knob 6. The two follower plates 3 can be driven to move along the bidirectional screw 5 through the threaded connection, and the two follower plates 3 can move away from or close to each other to support molds of different sizes, and a rotating connection relationship will be established. Because the support pad 4 can rotate and can be moved and adjusted as needed, it can adapt to molds of different sizes, thereby improving the flexibility and practicality of equipment application.

[0018] Specifically, when the utility model is used, the knob 6 is turned to drive the bidirectional screw 5 to rotate synchronously, and the two follower plates 3 are driven to move along the bidirectional screw 5 via the threaded connection. After moving to the appropriate position, the corresponding mold is placed on the two support pads 4. Because the support pad 4 can rotate, one end of the support pad 4 will be pressed when the mold is placed, so that the support pad 4 is tightly fitted with the bottom side wall of the mold, and then the motor 13 is started, and the active gear 16 is driven by the motor 13 to rotate, and the driven gear 17 can be driven to rotate synchronously through the transmission relationship of the meshing connection, and the lifting screw 12 can be driven to rise and fall through the threaded connection, so as to drive the pressing plate 10 to descend to press the top of the mold, and the pressing plate 10 and the support pad 4 cooperate with each other to achieve stable pressing of the mold, thereby preventing the mold from shaking during the production process and affecting the quality of metal wire production.
