[0001] The present application relates to the field of interventional consumable equipment, in particular to a shaping device. BACKGROUND

[0002] The patent document with the authorized announcement number CN115055604B discloses a metal wire shaping device, which can automatically shape the metal wire. After the device processes the metal wire, it directly outputs the shaped metal wire, and then transports the shaped metal wire to the place where it is needed. In this process, the shaped metal wire is easy to be contaminated, and in addition, it will be deformed after being extruded externally, affecting normal use. SUMMARY

[0003] The present application proposes a shaping device aiming at the above problems.

[0004] The technical scheme adopted by the present application is as follows:

[0005] A shaping device, comprising an integrated shaper, a rack, a shaping finger driving mechanism installed on the rack, and a twist sending mechanism installed on the rack;

[0006] The integrated shaper comprises:

[0007] a housing having a shaping cavity inside;

[0008] a metal wire limiting nozzle fixed in the shaping cavity for the metal wire to pass through;

[0009] a shaping finger slidingly installed in the shaping cavity, the shaping finger being used to cooperate with the metal wire at the outlet of the metal wire limiting nozzle to extrude and shape the metal wire;

[0015] The integrated shaper in the shaping device is a separate unit and can be taken out alone. During processing, the integrated shaper is installed on the positioning groove of the shell, and the piston assembly can rotate and move relative to the column under the driving of the torsion mechanism, and the shaping finger can make reciprocating linear motion under the driving of the shaping finger driving mechanism. Since the wire limiting nozzle and the shaping finger are both located in the shaping cavity of the shell, the entire shaping process is completed in the shaping cavity, which can effectively prevent the wire from being contaminated. After the shaping is completed, the integrated shaper can be taken out as a tool for storing and transporting the wire, and the wire can be taken out by opening the shell when needed. This form can prevent the shaped wire from being contaminated, and the wire will not be deformed under pressure because it is protected by the shell.

[0016] In actual use, the connection between the column and the shell means integral molding or fixed connection. The specific connection method can be fixed by fasteners, welded, or detachably fixed by threads.

[0017] In one embodiment of the present application, the shell has a taking and placing opening and a closure for closing the taking and placing opening.

[0018] In actual use, the closure has various forms. The closure can be screwed on the taking and placing opening of the shell, or it can be a sticker attached to the shell to cover the taking and placing opening.

[0019] In one embodiment of the present application, the side wall of the shell has a mounting opening. The integrated shaper further comprises:

[0020] A flexible member, the first end of the flexible member is installed at the mounting opening;

The flexible member covers the mounting opening, or the flexible member and the connecting rod together cover the mounting opening.

[0023] In one embodiment of the present application, the flexible member is a tower type telescopic sealing sleeve.

[0024] The flexible member is thus arranged to be telescopic, facilitating the connecting rod to have a larger stroke.

[0026] The connecting rod and the annular part are conveniently installed and matched. The movement of the connecting rod can drive the second end of the flexible member to move.

[0027] In one of the embodiments of the present application, the end of the connecting rod away from the shaping finger can be attracted by a magnet, or the connecting rod is provided with an elastic member, which is used to make the connecting rod have a tendency to move outwardly.

[0028] The shaping finger driving mechanism comprises:

[0029] A track is fixed on the frame and located at one side of the shell positioning groove, and the length direction of the track is the same as the axis direction of the connecting rod.

[0030] A driving member is slidingly installed on the track, and the driving member is provided with a driving groove, and the end of the driving member close to the shell positioning groove is provided with a matching structure matched with the connecting rod, the matching structure is matched with the connecting rod, and the connecting rod is synchronously reciprocated when the driving member reciprocates.

[0031] An eccentric wheel is arranged in the driving groove, and the rotation axis of the eccentric wheel is arranged in parallel with the axis of the eccentric wheel, and the eccentric wheel can drive the driving member to move on the track when the eccentric wheel rotates around the rotation axis.

[0032] A first driving motor is installed on the frame and used to drive the eccentric wheel to rotate around the rotation axis of the eccentric wheel.

[0033] In actual application, the matching structure can be a claw, a magnet, a vacuum chuck or the like.

[0034] In one of the embodiments of the present application, the matching structure is a magnet, and the matching structure is matched with the connecting rod in a magnetic manner.

[0035] That is, the end of the connecting rod away from the shaping finger can be attracted by a magnet. At this time, the material of the connecting rod is iron or other material that can be attracted by a magnet, or the connecting rod is provided with an iron block, a magnet or other material that can be attracted by the matching structure.

[0036] In one of the embodiments of the present application, when the connecting rod is provided with an elastic member, the matching structure is in contact with the connecting rod.

[0037] The elastic member makes the shaping finger have an initial position, and when matched with the driving member, the matching structure of the driving member only needs to push against the connecting rod to drive the shaping finger to move to the inside of the shell, and when the driving member retreats, the shaping finger can be driven to move to the outside of the shell by the elastic member.

[0038] In actual application, the elastic member can be a spring or a spring sheet or the like.

[0039] In one of the embodiments of the present application, the first end of the flexible member is installed on the outer wall of the shell.

[0040] The first end of the flexible piece is mounted on the outer side wall of the shell, without occupying the space in the shell, facilitating the arrangement of the shaping finger and the wire limiting nozzle.

[0043] The "axis of the wire limiting nozzle is parallel to the axis of the shell" means that the wire limiting nozzle is eccentrically arranged relative to the axis of the shell, and the straight line on which the movable path of the shaping finger is located is perpendicular to the intersection of the axis of the wire limiting nozzle and the axis of the shell. This arrangement can reasonably arrange the spatial positions of the wire limiting nozzle and the shaping finger, improve the space utilization, and make the structure more compact compared to the case where the axis of the wire limiting nozzle is coincident with the axis of the shell.

[0044] In one embodiment of the present application, the torsion mechanism comprises:

[0045] A rotating disc is rotatably mounted on the frame;

[0051] A linear lifting module is mounted on the frame, and the linear lifting module has a lifting seat;

[0052] A rotating disc is rotatably mounted on the lifting seat of the linear lifting module;

[0053] A second driving motor is used to drive the rotating disc to rotate;

[0054] A first clamping assembly is mounted on the rotating disc, and the first clamping assembly is used to clamp the piston assembly.

[0055] In one embodiment of the present application, the piston assembly further comprises:

[0056] a piston body, the wire locking element is fixedly installed at a first end of the piston body, a second end of the piston body is provided with a torsion pushing part, the first clamping assembly is used for clamping the torsion pushing part, and the torsion mechanism drives the piston assembly and the wire to rotate and move synchronously by clamping the torsion pushing part;

[0057] a limiting clamp used for clamping the piston body and limiting the maximum distance of the piston body entering the piston hole.

[0058] In actual application, the existing wire locking element can be used. In one embodiment of the present application, the wire locking element comprises:

[0059] a mounting member, an outer side wall of which is provided with external threads, the mounting member is fixedly installed at the first end of the piston body;

[0060] a resilient clamping member, which is installed on the mounting member and is provided with a plurality of resilient clamping claws, and the wire is passed through the middle of the plurality of resilient clamping claws in use;

[0061] a locking cap, which is provided with internal threads for screwing with the external threads of the mounting member, and an inner side wall of the locking cap is used for cooperating with the resilient clamping claws, so that the resilient clamping claws can clamp or release the wire by rotating the locking cap;

[0062] one end of the column body close to the wire limiting nozzle is provided with an anti-rotation groove, when the limiting clamp is removed, the locking cap is inserted into the anti-rotation groove by pushing the piston body towards the inside of the column body.

[0063] In actual application, preferably, the outer side wall of the end of the resilient clamping claw is a tapered surface, and the inner side wall of the locking cap is provided with a tapered surface, so that when the locking cap is locked, the tapered surface of the locking cap extrudes the tapered surface of the resilient clamping claw, and the tapered surfaces of the resilient clamping member are close to each other, thereby clamping and fixing the wire. When the locking cap is loosened, the tapered surface of the locking cap no longer extrudes the tapered surface of the resilient clamping claw, and the resilient clamping claw is elastically reset and no longer clamps the wire.

[0064] In actual application, the resilient clamping member can be an integral piece, and the plurality of resilient clamping claws are obtained by opening notches at the ends.

[0065] In one embodiment of the present application, the anti-rotation groove is square in cross section, and the outer side wall of the locking cap is provided with four convex edges, and after the locking cap is inserted into the anti-rotation groove, the four convex edges are located at the four corners of the anti-rotation groove, respectively.

[0066] In one of the embodiments of the present application, the anti-rotation groove is circular, and the inner side wall of the anti-rotation groove has a recess, and the outer side wall of the locking cover has a convex edge matched with the recess.

[0067] In one of the embodiments of the present application, the torsion pushing part has a positioning groove at one end close to the piston body, the cylinder has a positioning groove at one end away from the shell, and the limiting clamp has two positioning protrusions matched with the two positioning grooves respectively.

[0068] The shaping device further comprises a pair of sensors mounted on the frame, the pair of sensors comprising a transmitter and a receiver, and the pair of sensors are used to detect the limiting clamp when the integrated shaper is just installed in the shell positioning groove.

[0069] Through the cooperation of the positioning groove and the positioning protrusion, the circumferential position of the piston body can be ensured after assembly, so that the first clamping assembly can reliably clamp the torsion pushing part. Through the transmitter and the receiver, detection can be performed when the integrated shaper is initially placed. Only when the limiting clamp is detected, the shaping device can perform the next action. For example, when initially placed, the two positioning protrusions of the limiting clamp are respectively clamped into the two positioning grooves, at this time the piston body extends into the piston hole, and when the shell is placed into the shell positioning groove, the limiting clamp is in the laser path of the transmitter and the receiver at this time, which will break the laser. The pair of sensors judges according to the signal that the installation is in place, at this time the first clamping assembly works to clamp the torsion pushing part, and if the position is not correct, the laser between the transmitter and the receiver will not be broken, at this time the first clamping assembly will not work.

[0070] In one of the embodiments of the present application, the torsion pushing part has a clamping positioning part, which is a groove or a protrusion, and the first clamping assembly is used to clamp the clamping positioning part.

[0071] The first clamping assembly reliably interfaces with the torsion pushing part through the clamping positioning part, thereby driving the piston body to rotate and move. Through the cooperation of the pair of sensors, the positioning groove and the positioning protrusion, it can be ensured that the first clamping assembly can accurately clamp the clamping positioning part when it works.

[0072] In one of the embodiments of the present application, a second clamping assembly is further mounted on the frame, the outer side wall of the shell has a limiting groove, and the second clamping assembly is used to clamp at the limiting groove after the shell is installed in the shell positioning groove, so that the shell cannot move up and down along the axis of the shell.

[0073] In actual use, the second clamping assembly can be in various forms, such as a telescopic electromagnet, an electric push rod, an electric clamping jaw, a pneumatic clamping jaw, etc. Through the second clamping assembly, the shell can be prevented from moving up and down during processing.

[0074] In one of the embodiments of the present application, the sidewall of the shell positioning slot has a avoiding opening corresponding to the avoiding opening.

[0075] In one of the embodiments of the present application, the cylinder is arranged eccentrically relative to the axis of the shell.

[0076] The bottom wall of the shell positioning slot has a through hole, and the cylinder passes through the through hole.

[0077] The bottom wall of the shell has a first positioning structure, and the bottom wall of the shell positioning slot has a second positioning structure matched with the first positioning structure, wherein one of the first positioning structure and the second positioning structure is a positioning slot, and the other is a positioning column.

[0078] The first positioning structure and the second positioning structure are matched with each other to ensure the circumferential position of the shell and ensure the positioning accuracy.

[0079] In one of the embodiments of the present application, the bottom wall of the shell positioning slot is provided with a trigger switch, and when the shell is installed in place, the bottom wall of the shell contacts the trigger switch to trigger the trigger switch.

[0080] The beneficial effects of the present application are as follows: the integrated shaper in the shaping device is a separate unit and can be taken out alone. During processing, the integrated shaper is installed on the shell positioning slot, the piston assembly can be rotated and moved relative to the cylinder under the driving of the twist sending mechanism, and the shaping finger can be reciprocatingly linearly moved under the driving of the shaping finger driving mechanism. Since the metal wire limiting nozzle and the shaping finger are both located in the shaping cavity of the shell, the entire shaping process is completed in the shaping cavity, which can effectively prevent the metal wire from being contaminated. After the shaping is completed, the integrated shaper can be taken out as a tool for storing and transporting the metal wire, and the metal wire can be taken out by opening the shell when needed. This form of the present application can prevent the shaped metal wire from being contaminated, and the metal wire will not be deformed due to pressure because it is protected by the shell.

[0100] The present application will be described in detail below in conjunction with the accompanying drawings. Embodiment 1

[0101] As shown in Figures 10-13 , a shaping device comprises an integrated shaper 10, a rack 20, a shaping finger driving mechanism 30 mounted on the rack 20, and a twist sending mechanism 40 mounted on the rack 20.

[0102] As shown in Figures 1-9 , the integrated shaper 10 comprises:

[0103] a shell 11 having a shaping cavity 111 inside;

[0104] a wire limiting nozzle 12 fixed in the shaping cavity 111 for the wire 1 to pass through;

[0105] a shaping finger 13 slidingly installed in the shaping cavity 111, the shaping finger 13 being used to cooperate with the wire 1 at the outlet of the wire limiting nozzle 12 to extrude and shape the wire 1;

[0106] a column 14 connected with the shell 11, the column 14 having a piston hole 141, the axis of the piston hole 141 coinciding with the axis of the wire limiting nozzle 12; and

[0107] a piston assembly 15 mounted on the piston hole 141 of the column 14, the piston assembly 15 having a wire locking element 151, the piston assembly 15 being capable of rotating and moving relative to the column 14, in use, the wire 1 being fixed with the wire locking element 151 and passing through the wire limiting nozzle 12.

[0108] As shown in Figure 11 and 13 , the rack 20 comprises a shell positioning groove 21, the shell 11 of the integrated shaper 10 being used to be placed on the shell positioning groove 21; the shaping finger driving mechanism 30 being used to drive the shaping finger 13 to reciprocally slide; the twist sending mechanism 40 being used to drive the piston assembly 15 to rotate and move relative to the column 14.

[0109] The integrated shaper 10 in the shaping device is a separate unit and can be taken out alone. During processing, the integrated shaper 10 is installed on the shell positioning groove 21, the piston assembly 15 can rotate and move relative to the column 14 under the driving of the twist sending mechanism 40, and the shaping finger 13 can make reciprocating linear motion under the driving of the shaping finger driving mechanism 30. Since the wire limiting nozzle 12 and the shaping finger 13 are both located in the shaping cavity 111 of the shell 11, the entire shaping process is completed in the shaping cavity 111, which can effectively prevent the wire 1 from being contaminated. After the shaping is completed, the integrated shaper 10 can be taken out as a tool for storing and transporting the wire 1, and the wire 1 can be taken out by opening the shell 11 when needed. In this form, the shaped wire 1 will not be contaminated, and because it is protected by the shell 11, it will not be deformed under pressure.

[0110] In actual use, the connection between the column 14 and the shell 11 means that they are integrally formed or fixedly connected. The specific connection method can be fixed by fasteners, welded or detachably fixed by threads.

[0111] In this application, the wire 1 can be fixed with the wire locking element 151 after passing through the wire limiting nozzle 12, or the wire 1 can be fixed with the wire locking element 151 first and then pass through the wire limiting nozzle 12.

[0112] As shown in Figure 4 In this embodiment, the shell 11 has a taking and placing opening 112 and a closure 113 that covers the taking and placing opening 112.

[0113] In actual use, the closure 113 can be screwed onto the taking and placing opening 112 of the shell 11, or it can be a sticker that is attached to the shell 11 to cover the taking and placing opening 112.

[0114] As shown in Figure 1 and 4 In this embodiment, the side wall of the shell 11 has a mounting opening 114; the integrated shaper 10 further comprises:

[0115] A flexible member 16, a first end 161 of the flexible member is mounted at the mounting opening 114;

[0116] A slide rail 17 is fixed in the shaping cavity 111, and the shaping finger 13 is slidingly mounted on the slide rail 17;

[0117] A connecting rod 18 is connected to the shaping finger 13 at one end and connected to the second end 162 of the flexible member at the other end. The flexible member 16 covers the mounting opening 114, or the flexible member 16 and the connecting rod 18 together cover the mounting opening 114.

[0118] As shown in Figure 1and 4 As shown, in this embodiment, the flexible element 16 is a tower-shaped telescopic sealing sleeve. This design of the flexible element 16 allows for telescopic movement, facilitating a larger stroke for the connecting rod 18.

[0119] like Figure 4 As shown, the end of the connecting rod 18 away from the shaping finger 13 has an annular groove 181, and the second end 162 of the flexible member has an annular portion 163 that is embedded in the annular groove 181. This facilitates the installation and mating of the connecting rod 18 and the annular portion 163, and the movement of the connecting rod 18 can drive the second end 162 of the flexible member to move.

[0120] like Figure 10 and 11 As shown, in this embodiment, the shaping finger driving mechanism 30 includes:

[0121] The track 31 is fixed on the frame 20 and located on one side of the housing positioning groove 21. The length direction of the track 31 is the same as the axial direction of the connecting rod 18.

[0122] The driving component 32 is slidably mounted on the track 31. The driving component 32 has a driving groove 321. The end of the driving component 32 near the housing positioning groove 21 has a mating structure 322 that mates with the connecting rod 18.

[0123] An eccentric wheel 33 is disposed in the drive groove 321. The rotation axis of the eccentric wheel 33 is parallel to the axis of the eccentric wheel 33. When the eccentric wheel 33 rotates around the rotation axis, it can drive the drive component 32 to move on the track 31.

[0124] The first drive motor 34 is mounted on the frame 20 and is used to drive the eccentric wheel 33 to rotate around the rotation axis of the eccentric wheel 33.

[0125] In practical applications, the mating structure 322 can be a magnet, a vacuum suction cup, or other similar structure. In this embodiment, the mating structure 322 is a magnet, and it magnetically engages with the connecting rod 18. That is, the end of the connecting rod 18 furthest from the shaping finger can be attracted by the magnet. The connecting rod 18 can be made of iron or other materials that can be attracted by a magnet, or it can be made of a block of iron, a magnet, or other materials that can be attracted by the mating structure 322.

[0126] like Figure 1 and 11 As shown, in this embodiment, the first end 161 of the flexible member is mounted on the outer side wall of the housing 11.

[0127] The first end 161 of the flexible component is installed on the outer side wall of the housing 11, which will not encroach on the space inside the housing 11, and facilitates the arrangement of the shaping finger 13 and the wire limiting nozzle 12.

[0128] In the embodiment, the sliding direction of the shaping finger 13 is perpendicular to the axis of the wire limiting nozzle 12.

[0129] In the embodiment, the axis of the wire limiting nozzle 12 is parallel to the axis of the shell 11, and the straight line where the moving path of the shaping finger 13 is located is perpendicular to the intersection of the axis of the wire limiting nozzle 12 and the axis of the shell 11.

[0130] The “axis of the wire limiting nozzle 12 is parallel to the axis of the shell 11” means that the wire limiting nozzle 12 is eccentrically arranged relative to the axis of the shell 11, and the straight line where the moving path of the shaping finger 13 is located is perpendicular to the intersection of the axis of the wire limiting nozzle 12 and the axis of the shell 11. This arrangement can reasonably arrange the spatial positions of the wire limiting nozzle 12 and the shaping finger 13, improve the space utilization, and make the structure more compact compared to the case where the axis of the wire limiting nozzle 12 and the axis of the shell 11 coincide.

[0131] As shown in Figure 10 and 12 , in the embodiment, the twist sending mechanism 40 includes:

[0132] a rotating disc 41 rotatably installed on the rack 20;

[0133] a second driving motor 42 for driving the rotating disc 41 to rotate directly or through a transmission structure;

[0143] The piston body 152, the wire locking element 151 is fixedly installed at the first end 1521 of the piston body, the second end 1522 of the piston body is provided with a torsion pushing part 1523, the first clamping assembly 44 is used for clamping the torsion pushing part 1523, and the torsion mechanism 40 drives the piston assembly 15 and the wire 1 to rotate and move synchronously by clamping the torsion pushing part 1523.

[0144] The limiting clamp 153 is used for clamping on the piston body 152 and limiting the maximum distance of the piston body 152 entering the piston hole 141.

[0145] In actual application, the existing wire locking element 151 can be used. For example, Figure 4 、 6 As shown in Figs. 7, 8 and 9, in this embodiment, the wire locking element 151 comprises:

[0146] The mounting part 1511 is fixedly installed at the first end 1521 of the piston body, and the outer side wall is provided with external threads;

[0147] The elastic clamping part 1512 is installed on the mounting part 1511, and the elastic clamping part 1512 is provided with a plurality of elastic clamping claws 15121, and the wire 1 passes through the middle of the plurality of elastic clamping claws 15121 during use;

[0148] The locking cover 1513 is provided with internal threads matched with the external threads of the mounting part 1511, and the inner side wall of the locking cover 1513 is used for matching with the elastic clamping claws 15121, so that the elastic clamping claws 15121 can clamp or release the wire 1 by rotating the locking cover 1513;

[0149] The one end of the column 14 close to the wire limiting nozzle 12 is provided with an anti-rotation groove 142; when the limiting clamp 153 is abutted with the column 14 and the torsion pushing part 1523 respectively at two ends, the locking cover 1513 is not inserted into the anti-rotation groove 142, and when the limiting clamp 153 is removed and the piston body 152 is pushed into the column 14, the locking cover 1513 is inserted into the anti-rotation groove 142.

[0151] 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.

[0152] As shown in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13, in the embodiment, the torsion pushing part 1523 has a positioning groove 15231 at one end close to the piston body 152, the cylinder 14 has a positioning groove 15231 at one end away from the shell 11, and the limiting clamp 153 has a positioning protrusion 1531 matched with the two positioning grooves 15231, respectively. Figure 8 As shown in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13, in the embodiment, the torsion pushing part 1523 has a positioning groove 15231 at one end close to the piston body 152, the cylinder 14 has a positioning groove 15231 at one end away from the shell 11, and the limiting clamp 153 has a positioning protrusion 1531 matched with the two positioning grooves 15231, respectively.

[0153] Figure 6 As shown in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13, in the embodiment, the torsion pushing part 1523 has a positioning groove 15231 at one end close to the piston body 152, the cylinder 14 has a positioning groove 15231 at one end away from the shell 11, and the limiting clamp 153 has a positioning protrusion 1531 matched with the two positioning grooves 15231, respectively. 12 As shown in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13, in the embodiment, the torsion pushing part 1523 has a positioning groove 15231 at one end close to the piston body 152, the cylinder 14 has a positioning groove 15231 at one end away from the shell 11, and the limiting clamp 153 has a positioning protrusion 1531 matched with the two positioning grooves 15231, respectively.

[0154] As shown in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13, in the embodiment, the torsion pushing part 1523 has a positioning groove 15231 at one end close to the piston body 152, the cylinder 14 has a positioning groove 15231 at one end away from the shell 11, and the limiting clamp 153 has a positioning protrusion 1531 matched with the two positioning grooves 15231, respectively. Figure 12 As shown in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13, in the embodiment, the torsion pushing part 1523 has a positioning groove 15231 at one end close to the piston body 152, the cylinder 14 has a positioning groove 15231 at one end away from the shell 11, and the limiting clamp 153 has a positioning protrusion 1531 matched with the two positioning grooves 15231, respectively.

[0155] ​The cooperation of the positioning groove 15231 and the positioning protrusion 1531 ensures the circumferential position of the piston body 152 after assembly, thereby ensuring that the first clamping assembly 44 can reliably clamp the torsion pushing part 1523. The emitter 231 and the receiver 232 can detect when the integrated shaper 10 is initially placed, and only when the limiting clamp 153 is detected can the shaper device perform the next action. 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 determined to be in place according to the signal of the transmission 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.

[0156] 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.

[0157] 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 transmission 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] As shown in the embodiment, the cylinder 14 is arranged eccentrically relative to the axis of the shell 11; Figure 13

[0162] The bottom wall of the shell positioning groove 21 has a through hole 212, and the cylinder 14 passes through the through hole 212;

[0163] The bottom wall of the shell 11 has a first positioning structure 115, and the bottom wall of the shell positioning groove 21 has a second positioning structure 213 matched with the first positioning structure 115, one of the first positioning structure 115 and the second positioning structure 213 is a positioning groove, and the other is a positioning column.

[0164] The first positioning structure 115 and the second positioning structure 213 are matched with each other, which can ensure the circumferential position of the shell 11 and ensure the positioning accuracy.

[0165] As shown in the embodiment, the bottom wall of the shell positioning groove 21 is provided with a trigger switch 24, and when the shell 11 is installed in place, the bottom wall of the shell 11 contacts the trigger switch 24 to trigger the trigger switch 24. Figure 13 One of the specific working forms of the shaping device in the embodiment is as follows:

[0166] Prepare the integrated shaper 10, insert one end of the metal wire 1 into the metal wire 1 locking element, then lock the locking cover 1513, and fix the metal wire 1; in actual operation, the closed part 113 can be selected to be opened, and the metal wire 1 is inserted from top to bottom, or the cylinder 14 is inserted after the metal wire 1 is complete, the piston body 152 is pushed to the top until the two positioning lugs 1531 are respectively embedded in the two positioning grooves 15231;

[0167] Install the integrated shaper 10 on the rack 20, specifically, the shell 11 is placed in the shell 11 positioning groove, and the cylinder 14 is inserted into the through hole 212. When the trigger switch 24 is triggered, the limit clamp 153 is sensed by the optical sensor assembly, the second clamping assembly 22 works to clamp the shell 11, and the first clamping assembly 44 works to clamp the torsion pushing part 1523;

[0168] Then the shaping finger 13 driving mechanism works to drive the shaping finger 13 and the connecting rod 18 to move synchronously and reciprocally, and the torsion 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;

[0169] After shaping, the first clamping assembly and the second clamping assembly are released, and the integrated shaper 10 is taken out from the rack 20 for standby, and at this time the shaped metal wire 1 can be stored and fixed on the integrated shaper 10;

[0170] After shaping, the first clamping assembly and the second clamping assembly are released, and the integrated shaper 10 is taken out from the rack 20 for standby, and at this time the shaped metal wire 1 can be stored and fixed on the integrated shaper 10;​

[0171] 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.

[0172] Example 2

[0173] 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 shaping finger 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.

[0174] 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.

[0175] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
