Description

Technical Field

[0001] The present invention relates to a clamping device, and more specifically, to a clamping device for clamping a metal wire in a forging machine.

Background Art

[0002] A forging machine is used to continuously supply a metal wire as a material and forge a desired product (such as a washer, screw, bolt, nut, spring, etc.). Generally, a forging machine is provided with a wire feeding device for feeding the metal wire, and thereby the metal wire is continuously supplied.

[0003] In the wire feeding device, a driving member can be driven using a motor, an air cylinder, etc. as a power source, and a plurality of pairs of feeding rolls are arranged along the feeding direction with two feeding rolls as a pair. When the power source drives the driven member, the plurality of pairs of feeding rolls arranged in the feeding direction are rotationally driven by the movement of the driven member.

[0004] The metal wire is clamped by the plurality of pairs of feeding rolls, and each pair of feeding rolls rotates in opposite directions at a constant speed with respect to each other, so that the metal wire can be fed along the feeding direction by rolling friction.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, according to the conventional forging and forming machine, it is necessary to separately provide a driven shaft and a power source for driving a plurality of pairs of feed rolls. Therefore, when designing the conveying path, in addition to considering problems such as the flow line and interference, the configuration of the device is complicated and the power cost becomes high.

[0007] Moreover, since the size of the interval between each pair of feed rolls cannot be changed, only metal wire rods of the same wire diameter can be used. When attempting to forge using metal wire rods of different wire diameters, in order to obtain the interval between a pair of feed rolls corresponding to the diameter of the metal wire rod, it is necessary to remove those feed rolls and install feed rolls suitable for the metal wire rod to be forged. Also, in the forging process for manufacturing a relatively long product, feed rolls must be added, so it is necessary to adjust the combination of mechanisms. Thus, there is a drawback that it is troublesome for the user to use.

[0008] Therefore, in view of the above problems, an object of the present invention is to provide a clamping device used for conveying a metal wire rod in a forging and forming machine that can solve at least one of the above-mentioned drawbacks.

Means for Solving the Problem

[0009] As a means for achieving the above object, the present invention is a clamping device for clamping a wire rod in a forging and forming machine, comprising a slide movement mechanism, a clamping mechanism, and a control mechanism, the slide movement mechanism is arranged to be able to reciprocally slide in the front-rear direction, and a clamping groove is formed that is recessed upward in the vertical direction orthogonal to the front-rear direction from the bottom surface and serves as a place for clamping the wire rod. The clamping mechanism is disposed below the sliding mechanism, with a part extending into the clamping groove, and can move in the front-rear direction together with the sliding mechanism when the sliding mechanism is sliding, and can approach or depart from the sliding mechanism along the vertical direction. The control mechanism includes a guide plate that is below the clamping mechanism and extends along the front-rear direction, and the upper surface of which is in contact with the bottom of the clamping mechanism. The upper surface of the guide plate is divided into a first section, a second section connected to the first section, and a third section connected to the second section. The first section, the second section, and the third section are arranged in order from the rear to the front, and the third section is higher than the first section in the vertical direction. When the clamping mechanism moves from the first section via the second section to the third section, the clamping mechanism is pushed upward by the second section and the third section to approach the sliding mechanism and can clamp a part of the wire in the clamping groove together with the sliding part. A clamping device is provided, which is characterized by this.

Advantages of the Invention

[0010] According to the clamping device for a forging machine according to the present invention, the first section, the second section, and the third section of the guide plate cause the clamping mechanism to move in the vertical direction with respect to the sliding mechanism. In this way, the clamping mechanism and the sliding mechanism can clamp or release the clamping of a part of the wire. And the wire can be conveyed as the sliding mechanism slides. Moreover, the clamping mechanism and the sliding mechanism clamp the wire to be clamped in a linear contact manner, so that the deformation of the wire can be greatly reduced.

[0011] Also, even when attempting to manufacture (forge) a relatively long product, the wire can be clamped and conveyed without adding components to the clamping device, so it does not occupy extra space in the manufacturing process. Therefore, the utilization efficiency of the space in the factory can be improved. Not only that, even when clamping and conveying wires with different wire diameters or different lengths, it is possible to directly perform clamping and conveying without replacing the components in the clamping device, which is convenient for the user and has the effect of high versatility with respect to the wire.

[0020] The clamping device according to the present invention is for clamping a metal wire used as a raw material in a forging machine and feeding it along a predetermined feeding direction D (see FIG. 2).

[0021] As shown in FIGS. 1 to 3, the clamping device of this embodiment includes a base 1, a slide movement mechanism 2 disposed on the base 1 and capable of reciprocally sliding in the front-rear direction A with respect to the base 1, a clamping mechanism 3 disposed below the slide movement mechanism 2 and arranged to be able to clamp the wire together with the slide movement mechanism 2, a control mechanism 4 disposed below the clamping mechanism 3 for controlling the clamping mechanism 3 to be in a clamped state or a clamping release state, a drive mechanism 5 disposed on the base 1 corresponding to the control mechanism 4 and for driving the movement of the control mechanism 4 in the vertical direction B orthogonal to the front-rear direction A, and an adjustment mechanism 6 disposed on the base 1 and connected to the control mechanism 4 for adjusting the movement of the control mechanism 4 in the front-rear direction A.

[0022] As shown in FIGS. 2 to 4, the slide movement mechanism 2 includes a main sheet 21 and two positioning sheets 22.

[0023] As shown in FIGS. 2 and 4, a clamping groove 211 for clamping a wire rod is defined on the main sheet 21. Specifically, the clamping groove 211 is recessed upward in the vertical direction B from the bottom surface of the main sheet 21, that is, it opens downward.

[0024] As shown in FIGS. 3 and 4, the two positioning sheets 22 are located in the clamping groove 211 and fixed to the main sheet 21, and are arranged at intervals along the left - right direction C perpendicular to both the front - rear direction A and the vertical direction B.

[0025] As shown in FIG. 4, a groove portion 221 that opens upward in the vertical direction B is formed on each positioning sheet 22.

[0026] In this embodiment, the slide movement mechanism 2 can be incorporated into a slide pedestal configuration for actuating the linear movement of a punch in a forging machine. In this way, it does not occupy extra space in the manufacturing process.

[0027] As shown in FIGS. 2, 4, and 5, a part of the clamping mechanism 3 extends into the clamping groove 211, and can move in the front - rear direction A together with the slide movement mechanism 2 when the slide movement mechanism 2 slides, and can approach or depart from the slide movement mechanism 2 along the vertical direction B. Further, the clamping mechanism 3 includes a main body portion 31, two wing plate portions 32, an extension portion 33, and a roller portion 34.

[0028] As shown in FIG. 5, when viewed from the front - rear direction A, the main body portion 31 is located between the two positioning sheets 22 in the left - right direction C.

[0029] On the upper surface of the main body portion 31, a recess 311 for sandwiching a wire together with the main sheet 21 is formed with an upward-facing opening. The recess 311 extends in the front-rear direction A and has a width that decreases from top to bottom along the left-right direction C. In this embodiment, when viewed from the front-rear direction A, the recess 311 is V-shaped, but it is not limited thereto here.

[0030] As shown in FIGS. 4 and 5, the two wing plate portions 32 extend in opposite directions from both sides along the left-right direction C in the main body portion 31 and are respectively positioned within the groove portions 221 in the two positioning sheets 22. Here, the two wing plate portions 32 can move in the up-down direction B within the groove portions 221 in the two positioning sheets 22.

[0031] As shown in FIG. 5, the extension portion 33 extends downward in the up-down direction B (i.e., toward the guide plate 44 described later) from the main body portion 31. The roller portion 34 is pivotally connected to the bottom of the extension portion 33 as shown in FIGS. 2 and 5.

[0032] As shown in FIGS. 2, 3, and 5, the control mechanism 4 includes a housing 41, a carrier 42, a plurality of air cylinders 43, and a guide plate 44.

[0033] As shown in FIGS. 3 and 5, the housing 41 is disposed below the clamping mechanism 3 and below the guide plate 44 described later on the base 1 so as to be able to reciprocally slide in the front-rear direction A with respect to the base 1.

[0034] As shown in FIG. 5, the carrier 42 is disposed within the housing 41 and below the guide plate 44 described later and can move in the up-down direction B.

[0035] As shown in Fig. 2, each air cylinder 43 is arranged on the carrier 42 and protrudes upward from the housing 41 in the vertical direction B. In this embodiment, the number of air cylinders 43 is four, but it is not limited thereto.

[0036] As shown in Fig. 2, the guide plate 44 is located below the clamping mechanism 3, extends along the front-rear direction A, and in addition to the bottom surface being connected to the upper ends of a plurality of air cylinders 43, the upper surface is in contact with the bottom of the clamping mechanism 3. Specifically, the roller portion 34 of the clamping mechanism 3 is in contact with the guide plate 44 and can roll on the upper surface of the guide plate 44.

[0037] As shown in Fig. 2, the upper surface of the guide plate 44 is divided into a first section 441, a second section 442 connected to the first section 441, and a third section 443 connected to the second section 442.

[0038] Specifically, the first section 441, the second section 442, and the third section 443 are arranged in order from the rear to the front. Moreover, both the first section 441 and the third section 443 are planes, and the third section 443 is higher than the first section 441 in the vertical direction B. The second section 442 is an inclined surface connecting the first section 441 and the third section 443.

[0039] With such a configuration, when the clamping mechanism 3 moves from the first section 441 through the second section 442 to the third section 443, the clamping mechanism 3 is pushed upward by the second section 442 and the third section 443, approaches the slide movement mechanism 2, and can clamp a part of the wire in the clamping groove 211 together with the slide movement portion 2.

[0040] The drive mechanism 5 is for pushing the carrier 42 upward and moving the carrier 42, the guide plate 44, and the clamping mechanism 3 closer to the sliding mechanism 2, and as shown in FIGS. 3 and 6, includes a cam 51 and a follower 52.

[0041] As shown in FIG. 6, the cam 51 is pivotally connected to the base 1 and can rotate relative to the base 1.

[0042] As shown in FIG. 6, the follower 52 is configured to have both ends. Both ends of the follower 52 are respectively in contact with the outer peripheral surface of the cam 51 and the bottom surface of the carrier 42 of the control mechanism 4.

[0043] In this embodiment, rollers 521 are provided at both ends of the follower 52, and these rollers 521 are respectively in contact with the outer peripheral surface of the cam 51 and the bottom surface of the carrier 42. With such a configuration, one end of the follower 52 in contact with the outer peripheral surface of the cam 51 is periodically pushed downward, whereby the follower 52 is swung, and the carrier 42 is pushed upward by the other end of the follower 52 in contact with the bottom surface of the carrier 42.

[0044] As shown in FIGS. 3 and 5, the adjustment mechanism 6 is connected to the housing 41 and can reciprocally slide the housing 41 in the front - rear direction A with respect to the base 1, and includes a worm 61, a worm wheel 62, a screw shaft 63, and a sliding block 64.

[0045] As shown in FIG. 3, the worm 61 is arranged on the base 1 so as to be rotatable.

[0046] As shown in FIGS. 3 and 5, the worm wheel 62 meshes with the worm 61 and can rotate about a central axis parallel to the front - rear direction A as a rotation axis as the worm 61 rotates.

[0047] As shown in FIGS. 3 and 5, the screw shaft 63 extends along the central axis of the worm wheel 62 and is disposed so as to penetrate the worm wheel 62. It can rotate together with the worm wheel 62, and a screw thread (not shown) is formed on the outer peripheral surface.

[0048] As shown in FIGS. 3 and 5, the sliding block 64 is connected to the housing 41, is disposed so as to surround the screw shaft 63, and a screw thread that meshes with the screw thread formed on the outer peripheral surface of the screw shaft 63 is formed on the inside. It can reciprocate in the front-rear direction A along the extending direction of the screw shaft 63 by the rotation of the screw shaft 63.

[0049] More specifically, when the worm 61 is driven to rotate, the worm wheel 62 rotates as the worm 61 rotates. As a result, the screw shaft 63 fixed to the central axis of the worm wheel 62 rotates together with the worm wheel 62. When the screw shaft 63 rotates, the sliding block 64 can reciprocate in the front-rear direction A, and the housing 41 disposed on the sliding block 64 can move in the front-rear direction A as the sliding block 64 moves.

[0050] Hereinafter, a process of clamping and conveying a wire using the clamping device of the present embodiment will be described with reference to FIGS. 2, 5, 6, and 7.

[0051] First, the wire is passed through the main sheet 21 along the feeding direction D (see FIG. 2) so that a part of the wire is within the clamping groove 211.

[0052] Second, the slide movement mechanism 2 is slid along the feeding direction D, and as the slide movement mechanism 2 slides, the clamping mechanism 3 moves upward in the vertical direction B, that is, toward the main sheet 21 of the slide movement mechanism 2.

[0053] More specifically, when the roller portion 34 of the clamping mechanism 3 is in contact with the first section 441 of the guide plate 44 (see Fig. 2), since the main body portion 31 of the clamping mechanism 3 is at a certain distance from the slide movement mechanism 2, the wire is not clamped and the slide movement mechanism 2 can move relative to the wire. At this time, the wire does not move.

[0054] On the other hand, when the roller portion 34 of the clamping mechanism 3 moves from the first section 441 via the second section 442 to the third section 443 and is in contact with the third section 443 (see Fig. 7), the roller portion 34 and the main body portion 31 are pushed upward by the relatively high third section 443 so as to approach the slide movement mechanism 2. At this time, as shown in Fig. 6, the cam 51 drives the swing of the driven portion 52, whereby the bottom surface of the carrier 42 is pushed upward, and as the carrier 42 moves upward, the guide plate 44 and the clamping mechanism 3 are moved upward, and the main body portion 31 of the clamping mechanism 3 approaches the main sheet 21 of the slide movement mechanism 2 and clamps a part of the wire in the clamping groove 211 together with the main sheet 21.

[0055] Thirdly, after clamping the wire, the slide movement mechanism 2 continues to move in the feeding direction D. At this time, the roller portion 34 moves in the third section 443, and the main body portion 31 and the main sheet 21 continue to clamp a part of the wire, and the wire moves in the feeding direction D as the slide movement mechanism 2 slides in the feeding direction D.

[0056] Fourthly, when the slide movement mechanism 2 reaches the target point (dead point), the cam 51 returns the driven portion 52 downward. Thus, the main body portion 31 and the main sheet 21 no longer clamp a part of the wire. The slide movement mechanism 2 moves backward simultaneously. In this way, the main body portion 31 separates from the main sheet 21 to release the clamping of a part of the wire, and while the slide movement mechanism 2 returns to the original position, the roller portion 34 returns to the first section 441 of the guide plate 44.

[0057] By repeating the above steps (i.e., clamping, moving, and releasing the wire), the wire can be conveyed in the conveying direction D.

[0058] In this embodiment, when a part of the wire is clamped between the main body 31 of the clamping mechanism 3 and the main sheet 21 of the slide movement mechanism 2, since a part of the wire is in the recess 311 formed in a V shape, wires of different wire diameters can be clamped, and since the contact area between the main body 31 and the wire is large, deformation of the wire can be avoided when clamping the wire.

[0059] By clamping or releasing the wire in such a way that the main body 31 of the clamping mechanism 3 and the slide movement mechanism 2 approach or separate from each other in the vertical direction B, even when clamping and conveying metal wires of different wire diameters, metal wires of different lengths, or metal wires of other specifications, clamping and conveying can be directly performed without replacing the parts in the clamping device. Therefore, it is convenient for the user and can achieve the effect of high versatility with respect to the wire.

[0060] Furthermore, even when trying to manufacture (forge) a relatively long product, the wire can be clamped and conveyed without adding parts to the clamping device, so it does not occupy extra space in the manufacturing process. Therefore, the utilization efficiency of the space in the factory can be improved.

[0061] Moreover, in this embodiment, since the thrust of the plurality of air cylinders 43 can be adjusted, the strength of the force for the clamping mechanism 3 and the control mechanism 4 to rise and clamp the wire to the slide movement mechanism 2 can be adjusted. Thus, even when clamping wires of different wire diameters, the wire will not be deformed. Also, the sliding block 64 can adjust the position of the guide plate 44 by driving the movement of the control mechanism 4 in the conveying direction D.

[0062] It should be noted that in this embodiment, the clamping mechanism 3 clamps the wire in such a way that it approaches the sliding mechanism 2. However, it is not limited to this. In other embodiments, the sliding mechanism 2 can be designed with other configurations. For example, a part of the sliding mechanism 2 can be configured to extend below the clamping mechanism 3. In this case, the clamping method between the clamping mechanism 3 and the sliding mechanism 2 is reversed. More specifically, when the roller part 34 of the clamping mechanism 3 is in the third section 443, the main body part 31 of the clamping mechanism 3 moves upward away from a part of the sliding mechanism 2, and in this case, the wire is not clamped. On the other hand, when the roller part 34 moves from the third section 443 through the second section 442 to the first section 441, the main body part 31 moves downward approaching a part of the sliding mechanism 2, and in this case, the wire is clamped. In this way, the clamping device of this embodiment can adjust the clamping method for the wire and the feeding direction D by changing the setting of the sliding mechanism 2 according to needs.

[0063] In addition, in this embodiment, in addition to one clamping groove 211 being provided on the main sheet 21 of the sliding mechanism 2, and one main body part 31 of the clamping mechanism 3 being provided, taking the example of clamping and conveying one wire, it is not limited to this. According to needs, a plurality of main body parts 31 of the clamping mechanism 3 can be provided and a plurality of clamping grooves 211 can be provided on the main sheet 21, and it is also possible to clamp and convey the corresponding number of wires.

[0064] In summary, according to the clamping device according to the present invention, there is no need to separately provide a feeding roll, a connecting shaft, or a power source as in the prior art. By sharing the existing slide mechanism and power source, the wire can be clamped and conveyed.

[0065] Also, even when clamping and conveying wires with different wire diameters or different lengths, it is possible to directly execute clamping and conveying without replacing the parts in the clamping device, which is convenient for the user and has the effect of high versatility for the wire.

[0066] Furthermore, since the clamping mechanism 3 and the slide movement mechanism 2 clamp the wire to be clamped in a line contact manner with respect to the wire, the deformation of the wire can be greatly reduced. In addition, since the slide movement part 2 is incorporated into the slide pedestal configuration for operating the linear movement of the punch in the forging machine, the clamping device according to the present invention can be applied to an existing forging machine, and thus, there is no cost for updating or replacing the forging machine.

[0067] In the above, many specific details have been shown to facilitate the overall understanding of the present invention. However, it is obvious to those skilled in the art that one or more other embodiments can be implemented without showing specific details.

[0068] As described above, the preferred embodiments and variations of the present invention have been explained, but the present invention is not limited thereto, and all modifications and equivalent configurations are included as various configurations within the spirit and scope of the broadest interpretation.

[0069] According to the clamping device for a forging machine according to the present invention, when clamping and conveying wires of different lengths and wire diameters, it can be directly executed without replacing or adding parts, so that the space utilization efficiency and the versatility of the wires can be improved. Therefore, it has industrial applicability.
