Fig. 1 is a schematic view of an assembly structure of a wire processing apparatus, and a broken-line frame shown in the figure is a nip portion 3 of the wire processing apparatus, the nip portion 3 being in an open state in fig. 1. In contrast, fig. 2 is an enlarged view of the area, and the nip portion 3 in fig. 2 is in a nip state. Fig. 3 is a schematic cross-sectional view of the first clamping portion 1, the second clamping portion 2 and the nip portion 3. A dashed line L connecting the three is shown at the bottom of the three for the wire-carrying position.

Fig. 4-6 are schematic structural views of the wire processing device in different directions. Fig. 7-8 are an assembly view and a part view of the guide 7. In the above figures, a plurality of linear guides for driving the wire processing device can be seen, including a first linear guide 61, a second linear guide 62, a third linear guide 63, a fourth linear guide 64, a fifth linear guide 65. Wherein the first linear guide rail 61 and the second linear guide rail 62 are used to guide movement in the height direction (Z direction shown in fig. 4), the third linear guide rail 63 is used to guide movement in the wire-tightening direction (X direction shown in fig. 4), and the fourth linear guide rail 64 and the fifth linear guide rail 65 are used to guide movement perpendicular to the wire-tightening direction and in the horizontal direction (Y direction shown in fig. 4 and 7). In other words, the plurality of linear guides may move the respective regions of the wire processing device in a plurality of directions with respect to the wire to be processed.

In some embodiments, as shown in fig. 1 to 8, the wire processing device in the present embodiment includes a nip portion 3, a driving portion, a first clamping portion 1, and a second clamping portion 2. The press-fit portion 3 includes a first pressing piece 31 and a second pressing piece 32 arranged in pair, the first pressing piece 31 and the second pressing piece 32 are operable to move relatively and to be buckled on each other at opposite sides to form a press-fit chamber 33. In contrast, the first clamping portion 1 and the second clamping portion 2 are located on both sides of the nip 3, and at least one of the first clamping portion 1 and the second clamping portion 2 is operable to move in the extending direction of the nip chamber 33. The driving part is configured to drive the first clamping part 1 and the second clamping part 2 to tighten the wire, and drive the pressing part 3 to apply pressing force to a region to be pressed of the wire.

Alternatively, the driving portion in the present embodiment includes a plurality of drivers, and the drivers may be devices such as air cylinders or linear motors. The plurality of drivers include a first compact driver, a second compact driver, a first clamp driver, and a second clamp driver that can drive the first compact, the second compact, the first clamp, and the second clamp, respectively. For example, a second press block driver, which is vertically disposed on the top of the wire processing apparatus in fig. 1, may be used to drive the second press block 32 to move in the height direction.

Specifically, the nip chamber 33 is provided to extend along a straight line and to have 2 open ends 331 in the extending direction. In contrast, the first clamping portion 1 and the second clamping portion 2 are located on both sides of the two open ends 331 of the nip portion 3.

In the wire processing device according to the embodiment of the present invention, the first clamping portion 1 and the second clamping portion 2 are configured to be movable in the length direction of the pressing cavity 33, so as to ensure that the stretched wire can be located at the position of the pressing cavity 33. Therefore, when the pressing part 3 applies pressure to the pressing section of the wire, the wire in the pressing section can keep a stretched state, and the processing precision of the wire is improved. On the other hand, the first clamping part 1 and the second clamping part 2 are used for drawing the wire, so that the operation process of an operator is simplified. Meanwhile, the first clamping part 1 and the second clamping part 2 can accurately control the pulling force applied to the wire. After the pressing operation is finished, when the wire is cut, the cutting length of the wire can be well controlled according to the clamping positions of the first clamping part 1 and the second clamping part 2.

In some embodiments, heating holes 36 are opened on the first pressing block 31 and the second pressing block 32, and a plurality of heating bodies 9 are simultaneously disposed in the heating holes 36. The first pressing block 31 and the second pressing block 32 can transfer the heat of the heating body 9 into the pressing cavity 33, so that the wire processing device of the embodiment can perform hot pressing operation on the pressing region of the wire.

It will be readily appreciated that the strands are typically crimped into a disc-like configuration for ease of transport prior to processing into finished strands. For this reason, the wire material in a curled state needs to be straightened before processing, and the straightened wire material still takes a bent state without external restraint. Therefore, the embodiment utilizes the driving part to drive the first clamping part 1 and the second clamping part 2 to be away from each other, so that the wire can be kept in a stretched state in the process of pressing the wire by the pressing part 3. Simultaneously, when cutting after the wire rod pressfitting to the state of stretching straight, because of its inside sinle silk and outside coating all are in the state of stretching straight at this in-process, the length of the two can also keep the same after cutting. Especially when carrying out the hot pressing to the wire rod, the coating in hot pressing interval can closely laminate with the sinle silk, and still can be gapped between the sinle silk that is in not pressfitting region and the coating, and this wire rod inside can produce stress after making the hot pressing. From this, this embodiment can avoid cutting the back, and the phenomenon of backward shrink appears in terminal surface department sinle silk or the coating of wire rod, also can reduce simultaneously and avoid the wire rod terminal surface deckle edge to appear.

Further, the relative movement direction of the first pressing piece 31 and the second pressing piece 32 is perpendicular to the extension direction of the pressing cavity 33, one of the first pressing piece 31 and the second pressing piece 32 is provided with a plurality of positioning pins 34, and the other is provided with a plurality of pin holes 35 corresponding to the plurality of positioning pins 34. A plurality of positioning pins 34 are located on opposite sides of the first pressing piece 31 and the second pressing piece 32 and arranged on both sides of the pressing cavity 33. Set up first briquetting 31 and second briquetting 32 to the radial motion along the wire rod in this embodiment to set up a plurality of locating pins 34 respectively in the both sides of pressfitting chamber 33 simultaneously, guaranteed the accurate lock of two briquetting, still make first briquetting 31 and second briquetting 32 can exert the pressfitting power from the both sides of wire rod respectively, guarantee the form and position precision of the pressfitting chamber 33 that forms.

In some embodiments, as shown in fig. 1-8, the first press piece 31 has a first press face 311, the second press piece 32 has a second press face 321, the first press face 311 and the second press face 321 form the press cavity 33, and the first press face 311 includes an arc-shaped face. The first clamping part 1 comprises a first arc-shaped slot 11 for accommodating the wire, the second clamping part 2 comprises a second arc-shaped slot 21 for accommodating the wire, and the first arc-shaped slot 11 and the second arc-shaped slot 21 coincide with the arc-shaped surface in the extending direction.

Specifically, the cross-sectional shape of the arc-shaped surface in the extending direction of the pressing cavity 33 is an arc. The bottom of the cross section of the first arc-shaped groove 11 and the second arc-shaped groove 21 in the extending direction coincides with the arc line. The imaginary line L as shown in fig. 3 is located at the bottommost of the first arc-shaped slot 11, the arc-shaped face and the second arc-shaped slot 21.

Therefore, the present embodiment enables the wires placed in the first clamping portion 1 and the second clamping portion 2 to keep a straight extending state by arranging the bottom of the clamping position to be overlapped with the bottom of the stitching cavity 33 in the straightening direction of the wires. In the process that the first clamping portion 1 and the second clamping portion 2 are away from each other, the pressing section of the wire rod may be always located at the corresponding position of the first pressing surface 311.

In other embodiments, the first clamping portion 1 and the second clamping portion 2 are disposed at a position below the first pressing block 31, at this time, after the first clamping portion 1 and the second clamping portion 2 exert a pulling force, the wire can still be tightened, when the press-fit section is subjected to hot pressing, regions of the wire located at two ends of the press-fit section are bent towards obliquely lower sides of two sides, and at this time, the wire in the press-fit cavity 33 can still be in a tightened straight state.

In some embodiments, as shown in fig. 1-8, the first clamping portion 1 includes a base 12 and a clamping assembly 13, the clamping assembly 13 being removably mounted to the base 12. In the direction of extension of the press-fit chamber 33, the base 12 and the first pressure piece 31 are in a relatively stationary state, while the second clamping part 2 is moved relative to the first pressure piece 31. As shown by an arrow a in fig. 5, the second clamping portion 2 is used for the pulling operation in the present embodiment, and the base 12 of the first clamping portion 1 is relatively fixed. When processing the wire, the wire may be cut to a predetermined length, and then one end of the wire is fixed by the clamping component 13, and then the clamping component 13 is fixed on the base 12, and then the other end is extended to the corresponding position of the first clamping portion 1 and the first pressing surface 311. And rotating the cover plate of the second clamping part 2, pressing the cover plate on the wire rod, and moving the second clamping part 2 to draw the wire rod. And finally, after the hot pressing operation is finished, the wire in a stretched state can be cut to obtain a wire finished product with relatively accurate length.

The first positioning member 122 is telescopically disposed in the accommodating hole 1213 and abuts against a sidewall of the clamping assembly 13 when the clamping assembly 13 is mounted in the accommodating groove 121.

Specifically, the first positioning element 122 in this embodiment is a top ball, a spring is further disposed in the accommodating hole 1213, and one end of the spring abuts against the top ball and the other end abuts against the bottom of the accommodating hole.

In order to further ensure the length of the finished wire, in the present embodiment, the first positioning element 122 applies pushing forces to the clamping assembly 13 in different directions, so that the clamping assembly 13 abuts against the inner wall of the accommodating groove 121 under the action of the pushing forces, so as to realize the positioning of the accommodating groove 121 in the horizontal direction.

Specifically, the first fitting plane 1211 and the second fitting plane 1212 shown in fig. 9 are in mutually perpendicular positions, in which the second fitting plane 1212 is located perpendicular to the extending direction of the wire. In contrast, the first mounting plane 1211 is disposed perpendicular to the second mounting plane 1212. Thereby, the positional accuracy of the clamp assembly 13 on the horizontal plane is further ensured.

The clamp assembly 13 has a relief surface 131 corresponding to the second positioning member 123, and the relief surface 131 is recessed into the clamp assembly 13. When the clamping assembly 13 is installed in the accommodating groove 121, the second positioning member 123 is located between the avoiding surface 131 and the sidewall of the accommodating groove 121. The second positioning members 123 shown in fig. 9 are 2 in number and are provided along the extending direction of the first arc-shaped groove 11. The avoiding surface 131 and the second positioning member 123 of this embodiment are matched to perform a fool-proof function, so as to ensure that the clamping assembly 13 is not flipped over the base 12 when being mounted.

In some embodiments, as shown in fig. 1-10, the wire processing device further comprises a support frame 4, a first linear guide 61, and a second linear guide 62. The first linear guide rail 61 and the second linear guide rail 62 are mounted on the support frame 4, the second linear guide rail 62 is located above the first linear guide rail 61, the first pressing block 31 is movably arranged on the first linear guide rail 61, and the second pressing block 32 is movably arranged on the second linear guide rail 62.

In the present embodiment, the first presser 31 is disposed above the second presser 32, and both can be adjusted in the height direction so as to press-fit the wire rod. For example, the first pressing surface 311 of the first pressing piece 31 can be adjusted to the height position corresponding to the first arc-shaped groove 11 and the second arc-shaped groove 21, and the pressing can be realized only by moving the second pressing piece 32 in the hot pressing process.

In some embodiments, as shown in fig. 1-10, the wire processing device further includes a base frame 5 and a guide 7. The bottom frame 5 includes a bottom plate 51, the bottom plate 51 has a top surface 511, a bottom surface 512 and a window 513 penetrating the top surface 511 and the bottom surface 512, the supporting frame 4 is mounted on the bottom plate 51 and adjacent to the window 513, and the first pressing block 31 is located on the side of the top surface 511 of the bottom plate 51. The guide part 7 comprises a guide member 71, a guide block 72 and a guide column 73, wherein the guide block 72 is positioned on one side of the bottom surface of the bottom plate 51 and can move along the bottom surface 512, a guide groove 721 is formed in the lateral direction of the guide block 72, the guide groove 721 extends along the moving direction of the guide block 72, meanwhile, the guide groove 721 comprises an adjusting section 7211, one end of the adjusting section is close to the bottom plate 51, the other end of the adjusting section is far away from the bottom plate 51, the guide member 71 is positioned at the position of the window 513 and is provided with a first connecting end 711 and a second connecting end 712, the first connecting end 711 is connected with the first pressing block 31, one end of the guide column 73 is movably arranged in the guide groove 721, and the other end of the guide column 73 is connected with the second connecting end 712. When the guide block 72 is moving, the adjustment segment 7211 moves the guide 71 along the orientation of the window 513. In this embodiment, the guide slot 721 opened in the guide block 72 and in the lateral direction of the moving direction thereof is used to convert the horizontal movement of the guide block 72 into the vertical movement of the guide member 71, so as to drive the first press block 31 to move vertically.

It will be readily appreciated that the second press block driver which moves the second press block 32 is located at the top of the wire processing apparatus as shown in fig. 1, whereas the driver corresponding to the first press block 31 needs to be located near the first press block 31 in order to drive the first press block 31 to move.

In the embodiment, the connecting handle is arranged in the connecting hole in a penetrating way, so that the connecting column can rotate in the connecting hole. In contrast, the diameter of the circular cap is adapted to the width of the guide slot 721 and may be slightly smaller than the width of the guide slot 721. Thereby, the side wall of the round cap is allowed to contact with the side wall of the guide slot 721, and the guide post 73 is rotated in the coupling hole of the lug by the frictional force therebetween. This makes the driving of the guide 71 by the guide block 72 smoother.

As shown in the Y direction in fig. 4, the adjustment plate 8 in the present embodiment provides the first and second clamping portions 1 and 2 with adjustment capability in this direction. Therefore, the first pressing surface 311, the first arc-shaped groove 11 and the second arc-shaped groove 21 can be positioned on the same straight line through accurate adjustment in the Y direction, and when the wire is pulled, the pressing section of the stretched wire can still be positioned on the first pressing surface 311.

The wire processing apparatus in the above embodiments may process the wire in the following manner, as shown in fig. 1-10, and in some embodiments, first, the wire processing apparatus is calibrated. That is, the positions of the base 12, the second clamping part 2, the first presser 31 and the second presser 32 are adjusted by a plurality of linear guides so that the wire rod processing apparatus is suitable for processing a wire rod. The heating body 9 preheats the first compact 31 and the second compact 32 at the same time.
