Description

Technical Field

[0001] The utility model relates to the technical field of steel foot stamping, in particular to a continuous stamping machine for producing insulator steel feet. Background Art

[0002] High-voltage post insulators are composed of iron caps, tempered glass parts and steel feet, which are glued together with cement adhesive. Insulators are widely used in power systems and are generally external insulation. They work under atmospheric conditions. The busbars of overhead transmission lines, power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the earth (or grounding objects) or other conductors with potential differences. The insulator steel foot is a key component of the insulator in high-voltage transmission lines. Its main function is to connect to the main part of the insulator and fix the insulator to the support or tower of the transmission line.

[0003] Insulator steel legs are usually obtained by die stamping. Different dies need to be replaced for different steel legs. The traditional method is to fix the die with bolts.

In addition, the die replacement method is more troublesome, and the upper die and the lower die cannot be replaced at the same time. Therefore, a continuous stamping machine for insulator steel leg production is needed to solve the existing deficiencies. Utility Model Content

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the switching mechanism 8 includes a moving frame 801, a slider 802 and a receiving frame 803. The bottom end of the moving frame 801 is slidably connected to the top end of the base 1, and the bottom end of the slider 802 is slidably connected to the top end of the base 1.

[0027] The servo motor 805 is started to drive the driving rod 804 to rotate. Since the driving rod 804 is threadedly connected with the moving frame 801 and the slider 802, the moving frame 801 and the receiving frame 803 are pushed closer to each other. When the moving frame 801 is close to the bracket 2, the mounting seat 1 3 and the mounting seat 2 6 are respectively moved to the inner side of the card slot 1 11. During the movement of the moving frame 801, the rack 14 first meshes with the incomplete gear 901, and then the new upper mold 7 conflicts with the old upper mold 7, and the new lower mold 4 conflicts with the old lower mold 4, thereby pushing the old mold out of the two Inside the mounting seat, the driving rod 804 makes the movable frame 801 and the receiving frame 803 approach each other, so that the old mold will be moved to the inside of the receiving groove 10 respectively, so as to complete the replacement of the new mold and the old mold. Subsequently, the movable frame 801 and the receiving frame 803 are moved away from each other. Finally, the old mold can be taken out from the inside of the receiving groove 10. By means of the molds contacting each other, the synchronous replacement of the upper mold 7 and the lower mold 4 is quickly realized, which greatly improves the mold replacement speed, avoids mold replacement after the temperature has cooled down, and facilitates continuous operation.

[0028] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the limiting mechanism 9 includes an incomplete gear 901, a rotating rod 1 902, a rotating rod 2 903, a synchronous wheel 1 904, a synchronous wheel 2 905, a synchronous belt 906, a cone wheel 1 907, a cone wheel 2 908 and a push rod 909. The rotating rod 1 902 passes through the incomplete gear 901 and the synchronous wheel 1 904, and the rotating rod 1 902 is fixedly connected to the incomplete gear 901 and the synchronous wheel 1 904. The synchronous belt 906 is sleeved on the outer side of the synchronous wheel 1 904 and the synchronous wheel 2 905, and the synchronous wheel 1 904 and the synchronous wheel 1 904 are fixedly connected to the incomplete gear 901 and the synchronous wheel 1 904. The second 905 and the synchronous belt 906 form a belt transmission structure, the rotating rod 903 passes through the cone wheel 908, and the rotating rod 903 is fixedly connected to the cone wheel 908, the cone wheel 1 907 is meshed with the cone wheel 908, and the top of the push rod 909 is fixedly connected to the bottom of the rotating rod 903, the incomplete gear 901 and the synchronous wheel 1 904 are both movably connected to the inside of the mounting seat 1 3 through the rotating rod 1 902, and the tooth part of the incomplete gear 901 is located on the outside of the mounting seat 1 3, the cone wheel 2 908 and the push rod 909 are The cone wheel 1 907 is movably connected to the inside of the mounting seat 1 3 through a rotating rod, and the rotating shaft of the cone wheel 1 907 passes through the synchronous wheel 2 905, and the rotating shaft of the cone wheel 2 908 is fixedly connected to the synchronous wheel 2 905. The limiting mechanism 9 also includes an insertion rod 910, a reset spring 911 and a connecting plate 912. The insertion rod 910 and the reset spring 911 are distributed in a linear array. The reset springs 911 are respectively sleeved on the outside of the insertion rod 910, and the same end of the insertion rod 910 is fixedly connected to the connecting plate. One side of the connecting plate 912, and the insertion rod 910 and the connecting plate 912 are movably connected to the inside of the mounting seat 3, one end of the return spring 911 is fixedly connected to the inside of the mounting seat 3, and the other end of the return spring 911 is fixedly connected to one side of the connecting plate 912, and several sockets 13 are provided on both sides of the upper mold 7 and both sides of the lower mold 4, and the insertion rod 910 is respectively adapted to the sockets 13, and the racks 14 are fixedly connected to the inside of the slot 11 on both sides, and the racks 14 are respectively meshed with the incomplete gear 901.

[0029] The rack 14 first meshes with the incomplete gear 901, thereby driving the incomplete gear 901 to rotate, so that the rotary rod 1 902 and the synchronous wheel 1 904 rotate synchronously, and under the action of the synchronous belt 906, the synchronous wheel 2 905 and the cone wheel 1 907 rotate synchronously, thereby driving the cone wheel 2 908 and the rotary rod 2 903 to rotate synchronously, so that the push rod 909 rotates around the rotary rod 2 903, and the push rod 909 conflicts with one side of the connecting plate 912, so that the connecting plate 912 is inside the mounting seat 1 3, driving the insertion rod 910 to separate from the socket 13, and the reset spring 911 is stretched and lengthened. At this time, the mounting seat 1 3 releases the limit on the old upper mold 7, and similarly, the mounting seat 2 6 releases the limit on the old lower mold 4. 801 continues to move, and when the rack 14 moves away from the incomplete gear 901, the inner wall of the moving frame 801 is close to the outer side surface of the mounting seat 3, thereby preventing the incomplete gear 901 from rotating in the opposite direction. Only when the rack 14 moves in the opposite direction can it drive the incomplete gear 901 to rotate in the opposite direction, so that the insertion rod 910 is reinserted into the interior of the socket 13. Through the cooperation of multiple insertion rods 910 and the socket 13, the stability of the upper mold 7 and the lower mold 4 on the inner side of the mounting seat is improved, and through the cooperation of the rack 14 and the incomplete gear 901, the mounting seat is cleverly released from the restriction of the mold when the mold is replaced, and when the mold is replaced, the insertion rod 910 can be used to limit the position of the mold, thereby improving the continuity of the operation.

[0030] Working principle: When in use, first, use the moving column 5 at the lower end of the bracket 2 to control the mounting seat 2 6 to move downward until it is close to the mounting seat 1 3, and install the new upper mold 7 and the lower mold 4 to the inner side of the moving frame 801 through the card slot 12, then start the servo motor 805 to drive the driving rod 804 to rotate. Since the driving rod 804 is threadedly connected with the moving frame 801 and the slider 802, the moving frame 801 and the receiving frame 803 are pushed to approach each other. When the moving frame 801 approaches the bracket 2, the mounting seat 1 3 and the mounting seat 2 6 are respectively moved to the inner side of the card slot 11, and the moving frame 801 and the receiving frame 803 are pushed to approach each other. During the movement of the moving frame 801, the rack 14 first meshes with the incomplete gear 901, thereby driving the incomplete gear 901 to rotate, so that the rotating rod 1 902 and the synchronous wheel 1 904 rotate synchronously, and under the action of the synchronous belt 906, the synchronous wheel 2 905 and the cone wheel 1 907 rotate synchronously, thereby driving the cone wheel 2 908 and the rotating rod 2 903 to rotate synchronously, so that the push rod 909 rotates around the rotating rod 2 903, and the push rod 909 conflicts with one side of the connecting plate 912, so that the connecting plate 912 is inside the mounting seat 1 3, driving the plug rod 910 to separate from the socket 13, and then returning to the original position. The positioning spring 911 is stretched and lengthened, and at this time, the mounting seat 13 releases the limit on the old upper mold 7. Similarly, the mounting seat 26 releases the limit on the old lower mold 4. As the moving frame 801 continues to move, when the rack 14 moves away from the incomplete gear 901, the inner wall of the moving frame 801 is close to the outer side surface of the mounting seat 13, thereby preventing the incomplete gear 901 from rotating in the opposite direction. Only when the rack 14 moves in the opposite direction can it drive the incomplete gear 901 to rotate in the opposite direction, so that the insertion rod 910 is reinserted into the interior of the insertion hole 13; then the new upper mold 7 conflicts with the old upper mold 7, and the new lower mold 4 conflicts with the old lower mold The tool 4 contacts each other, thereby pushing the old mold out of the two mounting seats, and the driving rod 804 makes the movable frame 801 and the receiving frame 803 approach each other, so that the old mold will be moved to the inside of the receiving groove 10 respectively, thereby completing the replacement of the new mold and the old mold, and then, the movable frame 801 and the receiving frame 803 are moved away from each other. Finally, the old mold can be taken out from the inside of the receiving groove 10, and the rack 14 moves in the opposite direction, so that the insertion rod 910 is reinserted into the inside of the insertion hole 13 of the new mold, so that the new mold is re-fixed inside the mounting seat, and then the insulator steel foot stamping operation can be carried out.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
