DETAILED DESCRIPTION

[0027] The specific embodiments of the utility model are described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but are not used to limit the scope of the utility model.

[0028] Referring to Figure 1 , the rack 1 of the wave winding forming device is in contact with the foundation, and the upper end of the rack 1 is a working platform 2, the straightening machine 3 on the working platform 2 is used for straightening operation of the wire, the straightened wire is fixedly connected with the wire clamp 7 installed on the second guide rail 6 2, the wire clamp 7 is pulled back manually, so that the wire is located in the gap between the two forming modules 5, the forming module 5 is installed on the first guide rail 4, and the distance between each forming module 5 can be adjusted through the corresponding locking bolt, so that the demand of different wave winding production is conveniently met, the two forming modules 5 are arranged in a zipper type, can be clamped into the gap between each other, and the forming operation of the wire can be completed through extrusion.

[0029] Referring to Figures 2-4There is a first slider 8 between the molding module 5 and the first guide rail 4, which facilitates the adjustment of the relative position of the molding module 5. The bottom support 9 on the molding module 5 is used to install the slide seat 10. The telescopic rod 11 is inserted into the grass corresponding to the slide seat 10. One end of the telescopic rod 11 is fixedly connected to the adapter block 12. The molding die head 13 is on the adapter block 12. When adjusting the molding die head 13, the screw 27 needs to be rotated to drive the molding die head 13 to move back and forth.

[0030] When forming wire, follow Figure 1 In the order from left to right, the corresponding forming modules 5 are moved inward in a staggered manner, and each forming module 5 interlocks with each other. When the forming module 5 presses the wire, the wire deforms and can pull the wire holder 7 at its tail end to move to the left. Finally, all the forming modules 5 are engaged together in a zipper-like manner to complete the wire forming operation.

[0031] The initial feed rate of the forming die 13 is generally 95% of the feed rate required after wire forming. After all the forming dies 13 are initially adjusted into place, the adjustment operation is repeated to push the forming die 13 into place completely to overcome metal springback.

[0032] The wire groove 14 on the side wall of the forming die head 13 is used to hold the wire in place, thereby improving the stability of the wire during forming.

[0033] The guide block 15 at the front end of the forming die head 13 is shaped in an inclined manner to facilitate the insertion of the wire.

[0034] See Figure 5 A vertical plate 16 is fixed on the working platform 1. The wire guide seat 17 and the pressure plate seat 18 on the vertical plate 16 are used for guiding and locking the wire. The groove on the wire guide seat 17 is used for the wire to pass through and provides guidance for the front end of the wire. The screw 19 is screwed into the screw hole on the pressure plate seat 18. After the screw 19 rotates, it drives the pressure block 20 to move down in the pressure block guide groove 21, which can perform the wire clamping operation and prevent the wire at the wire inlet from moving during the forming operation, thus ensuring the accuracy and stability of the processing.

[0035] See Figure 6 The wire clamp 7 is movably connected between the second slider 22 and the second guide rail 6. Firstly, it facilitates the straightening of the wire during the initial preparation work. Then, during the forming operation, when the forming die head 13 causes the wire to deform, the wire guide seat 7 can move forward under the pull of the wire without breaking the wire.

[0036] The swing head 24, which is movably mounted on the adapter frame 23 of the wire guide seat 7, allows the tail end of the wire to swing slightly, preventing excessive twisting of the tail end of the wire during the forming operation.

[0037] The swing head 24 has an opening for the wire to pass through, and the locking bolt 25 can press the tail end of the wire passing through the opening after driving the wire pressing head 26 to move downward, so as to complete the locking and fixing of the tail end of the wire.

[0038] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;

[0039] Secondly: the utility model discloses the embodiment in the drawing, only relate to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, under the condition of not conflicting, the same embodiment and different embodiments of the utility model can be combined with each other.

[0040] Finally: the above is only the preferred embodiment of the utility model, and is not used for limiting the utility model, it should be pointed out that for ordinary skilled person in the art, on the premise of not departing from the technical principle of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the utility model.
