Figure 4 As shown in the drawings, the connection rod 18 has a ring-shaped groove 181 at the end away from the shaping finger 13, and the second end 162 of the flexible member has a ring-shaped portion 163 embedded in the ring-shaped groove 181. The connection rod 18 and the ring-shaped portion 163 are conveniently mounted and matched, and the movement of the connection rod 18 can drive the second end 162 of the flexible member to move.

[0080] Figure 10 As shown in the drawings, in the embodiment, the shaping finger driving mechanism 30 comprises: 11 a track 31 fixed on the frame 20 and located at one side of the shell positioning groove 21, the length direction of the track 31 is the same as the axis direction of the connection rod 18;

[0081] a driving member 32 slidably installed on the track 31, the driving member 32 has a driving groove 321 thereon, and the end of the driving member 32 close to the shell positioning groove 21 has a matching structure 322 matched with the connection rod 18;

When the locking cover 1513 is loosened, the tapered surface of the locking cover 1513 no longer extrudes the tapered surface of the elastic clamping jaw 15121, and the elastic clamping jaw 15121 is elastically reset and no longer clamps the metal wire 1.

[0111] In actual use, the elastic clamping member 1512 can be an integral piece, and a plurality of elastic clamping jaws 15121 are obtained by opening notches at the ends.

For example, when initially placed, the two positioning protrusions 1531 of the limiting clamp 153 are respectively clamped into the two positioning grooves 15231, at this time the piston body 152 extends into the piston hole 141, and when the shell 11 is placed into the shell positioning groove 21, at this time the limiting clamp 153 is in the laser path of the emitter 231 and the receiver 232, which will break the laser, and the installation is judged to be in place according to the signal of the optical sensor assembly, at this time the first clamping assembly 44 works to clamp the torsion pushing part 1523, and if the position is not correct, the laser between the emitter 231 and the receiver 232 will not be broken, at this time the first clamping assembly 44 will not work.

[0116] As shown in Figure 1 and 10 , in this embodiment, the torsion pushing part 1523 has a clamping positioning part 15232, which is a groove or a protrusion, and the first clamping assembly 44 is used to clamp the clamping positioning part 15232.

[0117] The first clamping assembly 44 reliably interfaces with the torsion pushing part 1523 through the clamping positioning part 15232, thereby driving the piston body 152 to rotate and move. Through the cooperation of the optical sensor assembly, the positioning groove 15231 and the positioning protrusion 1531, it can be ensured that the first clamping assembly 44 can accurately clamp the clamping positioning part 15232 when it works.

[0118] As shown in Figure 11 and 13 , in this embodiment, a second clamping assembly 22 is also installed on the rack 20, and the outer side wall of the shell 11 has a limiting groove 116, and the second clamping assembly 22 is used to clamp at the limiting groove 116 after the shell 11 is installed in the shell positioning groove 21, so that the shell 11 cannot move up and down along the axis of the shell 11.

[0119] In actual use, the second clamping assembly 22 can be in various forms, such as a telescopic electromagnet, an electric push rod, an electric clamping jaw, a pneumatic clamping jaw, etc. The second clamping assembly 22 can prevent the shell 11 from moving up and down during processing.

[0120] As shown in Figure 11 and 13 , in this embodiment, the side wall of the shell positioning groove 21 has a avoiding opening 211, and the limiting groove 116 corresponds to the avoiding opening 211.

[0121] like Figure 13 As shown, in this embodiment, the column 14 is eccentrically positioned relative to the axis of the housing 11;

[0122] The bottom wall of the housing positioning groove 21 has a through hole 212, through which the column 14 passes;

[0123] The bottom wall of the housing 11 has a first positioning structure 115, and the bottom wall of the housing positioning groove 21 has a second positioning structure 213 that cooperates with the first positioning structure 115. Of the first positioning structure 115 and the second positioning structure 213, one is a positioning groove and the other is a positioning post.

[0124] The first positioning structure 115 and the second positioning structure 213 work together to ensure the circumferential position of the housing 11 and ensure positioning accuracy.

[0125] like Figure 13 As shown, in this embodiment, a trigger switch 24 is installed on the bottom wall of the housing positioning groove 21. When the housing 11 is installed in place, the bottom wall of the housing 11 contacts the trigger switch 24, triggering the trigger switch 24.

[0126] One specific working mode of the shaping equipment in this embodiment:

[0127] Prepare the integrated molding tool 10, insert one end of the metal wire 1 into the metal wire 1 locking element, and then lock the locking cover 1513 to fix the metal wire 1. In actual operation, you can choose to open the closure 113 and insert the metal wire 1 from top to bottom, or you can insert the column 14 from bottom to top after the metal wire 1 is complete, and push the piston body 152 to the top until the two positioning protrusions 1531 are respectively embedded in the two positioning grooves 15231.

[0128] The integrated shaping device 10 is installed on the frame 20. Specifically, the housing 11 is placed in the positioning groove of the housing 11, and the column 14 is inserted into the through hole 212. When the trigger switch 24 is triggered, the through-beam sensor assembly senses the limit clamp 153, the second clamping assembly 22 works to clamp the housing 11, and the first clamping assembly 44 works to clamp the torsion push part 1523.

[0129] Then the shaping finger 13 drive mechanism works to drive the shaping finger 13 and the connecting rod 18 to move back and forth synchronously, and the twisting mechanism 40 works to drive the piston assembly 15 to move up and down and rotate, so that the metal wire 1 is shaped in the shaping cavity 111.

[0130] After the shaping is completed, the first clamping component and the second clamping component are released, and the integrated shaping device 10 is taken out from the frame 20 for later use. At this time, the shaped metal wire 1 can be stored and fixed on the integrated shaping device 10.

[0131] When it is necessary to remove the metal wire 1, remove the limit clip 153, push the piston body 152 into the cylinder 14, insert the locking cover 1513 into the anti-rotation groove 142, rotate the locking cover 1513 to make the elastic claw 15121 release the metal wire 1, open the closure 113, and take out the metal wire 1.

[0132] Example 2

[0133] like Figure 14 As shown, the difference between this embodiment and Embodiment 1 is that the end of the connecting rod 18 away from the slide block can be prevented from being attracted by the magnet. In this embodiment, an elastic element 50 is sleeved on the connecting rod 18. The elastic element 50 is used to give the connecting rod 18 a tendency to move outward, and the mating structure contacts and engages with the connecting rod.

[0134] This configuration allows the shaping finger 13 to have an initial position. When it cooperates with the driving member 32, the driving member 32 only needs to hold the connecting rod 18 to drive the shaping finger 13 to move inward toward the housing 11. When the driving member 32 retracts, the elastic member 50 can drive the shaping finger 13 to move outward toward the housing 11. In practical applications, the elastic member 50 can be a spring or a sheet, etc.

[0135] The above description is only a preferred embodiment of the present utility model and does not limit the scope of patent protection of the present utility model. Any equivalent structural transformations made based on the content of the present utility model specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present utility model.
