Description

[Technical Field]

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

[0002] A forging machine is a machine that continuously supplies metal wire as material and forges desired products (e.g., washers, screws, bolts, nuts, springs, etc.) Generally, a forging machine is provided with a wire feeding device for feeding the metal wire, which allows the metal wire to be continuously supplied.

[0003] In the wire rod feeding device, the driven member can be driven by a power source such as a motor or an air cylinder, and multiple pairs of feed rolls, each consisting of two feed rolls, are arranged along the feeding direction. When the power source drives the driven member, the movement of the driven member causes the multiple pairs of feed rolls arranged in the feeding direction to rotate and be driven.

[0004] The metal wire is clamped between the pairs of feed rolls, and each pair of feed rolls rotates in opposite directions at a constant speed, allowing the metal wire to be fed in the feed direction by rolling friction force. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Taiwan Patent No. I239875 Summary of the Invention [Problem to be solved by the invention]

[0006] However, conventional forging machines require the installation of separate driven shafts and power sources to drive the pairs of feed rolls, which means that problems such as flow lines and interference must be considered when designing the transport path, and the device configuration is complex, resulting in high power costs.

[0007] Furthermore, since the gap between each pair of feed rolls cannot be changed, only metal wires of the same diameter can be used. When forging metal wires of different diameters, the feed rolls must be removed and new feed rolls appropriate for the wire to be forged must be installed to obtain a gap between the feed rolls corresponding to the diameter of the wire. Furthermore, in forging processes for producing relatively long products, additional feed rolls must be added, which necessitates adjustment of the mechanism combination. As such, there is a drawback in that it is time-consuming for users to use.

[0008] Therefore, in view of the above problems, the present invention aims to provide a clamping device used to transport metal wire in a forging machine that can solve at least one of the above drawbacks. [Means for solving the problem]

[0009] As a means for achieving the above object, the present invention provides a clamping device for clamping a wire rod in a forging machine, comprising: The device includes a slide movement mechanism, a clamping mechanism, and a control mechanism, the slide movement mechanism is arranged to be able to slide back and forth in a front-to-rear direction, and has a clamping groove formed therein that is recessed upward in a vertical direction perpendicular to the front-to-rear direction from a bottom surface and that serves as a place for clamping the wire rod; the clamping mechanism is disposed below the sliding movement mechanism, a portion of which extends into the clamping groove, and is capable of moving in the front-to-rear direction together with the sliding movement mechanism when the sliding movement mechanism is sliding, and is capable of moving toward or away from the sliding movement mechanism along the up-down direction; the control mechanism includes a guide plate that is located below the clamping mechanism, extends along the front-rear direction, and has an upper surface that abuts against a bottom portion of the clamping mechanism; an 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 rear to front, and the third section is higher than the first section in the up-down direction; A clamping device is provided, characterized in that 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, approaches the sliding movement mechanism, and together with the sliding movement part, can clamp a portion of the wire in the clamping groove. [Effects of the Invention]

[0010] In the clamping device for a forging machine according to the present invention, the clamping mechanism moves vertically relative to the sliding mechanism by the first, second, and third sections of the guide plate, so that the clamping mechanism and the sliding mechanism can clamp and release a portion of the wire rod. The wire rod can be transported as the sliding mechanism slides. Furthermore, the clamping mechanism and the sliding mechanism clamp the wire rod to be clamped in a linear contact manner, which significantly reduces deformation of the wire rod.

[0011] Furthermore, even when manufacturing (forging) a relatively long product, the wire rod can be clamped and conveyed without adding any additional parts to the clamping device, so no extra space is taken up in the manufacturing process. This improves the space utilization efficiency in the factory. Furthermore, even when clamping and conveying wire rods of different diameters or lengths, clamping and conveying can be performed directly without replacing parts in the clamping device, which is convenient for users and has the effect of being highly versatile for wire rods.

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

[0021] As shown in Figures 1 to 3, the clamping device of this embodiment comprises a base 1, a slide movement mechanism 2 arranged on the base 1 and capable of sliding back and forth in the forward and backward direction A relative to the base 1, a clamping mechanism 3 arranged below the slide movement mechanism 2 so as to be able to clamp the wire together with the slide movement mechanism 2, a control mechanism 4 arranged below the clamping mechanism 3 for controlling the clamping mechanism 3 to enter a clamping state or a clamp release state, a drive mechanism 5 arranged on the base 1 corresponding to the control mechanism 4 for driving the movement of the control mechanism 4 in the up and down direction B perpendicular to the forward and backward direction A, and an adjustment mechanism 6 arranged on the base 1 connected to the control mechanism 4 and for adjusting the movement of the control mechanism 4 in the forward and backward direction A.

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

[0023] 2 and 4, a clamping groove 211 is defined in the main sheet 21 to clamp the wire. Specifically, the clamping groove 211 is recessed upward in the up-down direction B from the bottom surface of the main sheet 21, i.e., it opens downward.

[0024] As shown in Figures 3 and 4, the two positioning sheets 22 are located within the clamping groove 211 and fixed to the main sheet 21, and are arranged at a distance from each other along the left-right direction C, which is perpendicular to both the front-to-back direction A and the up-down direction B.

[0025] As shown in FIG. 4, each positioning sheet 22 has a groove 221 that opens upward in the up-down direction B.

[0026] In this embodiment, the slide mechanism 2 can be incorporated into a slide base arrangement for actuating the linear movement of a punch in a forging machine, thus not taking up extra space in the manufacturing process.

[0027] 2, 4, and 5, the clamping mechanism 3 partially extends into the clamping groove 211, and can move in the front-to-rear direction A together with the sliding movement mechanism 2 when the sliding movement mechanism 2 slides, and can move toward or away from the sliding movement mechanism 2 in the up-and-down direction B. The clamping mechanism 3 also includes a main body 31, two blade portions 32, an extension portion 33, and a roller portion 34.

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

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

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

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

[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 Figures 3 and 5, the housing 41 is arranged on the base 1 below the clamping mechanism 3 and below the guide plate 44 described later so that it can slide back and forth in the forward and backward direction A relative to the base 1.

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

[0035] 2, each air cylinder 43 is disposed 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 is not limited thereto.

[0036] 2, the guide plate 44 is located below the clamping mechanism 3, extends in the front-rear direction A, and has a bottom surface connected to the upper ends of the multiple air cylinders 43, and an upper surface abutting against the bottom of the clamping mechanism 3. Specifically, the roller unit 34 of the clamping mechanism 3 abuts against 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 back to front. The first section 441 and the third section 443 are all flat, and the third section 443 is higher than the first section 441 in the up-down direction B. The second section 442 is an inclined surface that connects the first section 441 and the third section 443.

[0039] With this configuration, when the clamping mechanism 3 moves from the first section 441 via 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 sliding movement mechanism 2, and together with the sliding movement part 2, can clamp a portion of the wire in the clamping groove 211.

[0040] The drive mechanism 5 pushes the carrier 42 upward to move the carrier 42, the guide plate 44, and the clamping mechanism 3 closer to the slide movement mechanism 2, and as shown in Figures 3 and 6, it is equipped with 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] 6, the follower part 52 is configured to have two ends. The two ends of the follower part 52 abut against the cam 51 and the bottom surface of the carrier 42 of the control mechanism 4, respectively.

[0043] In this embodiment, rollers 521 are provided on both ends of follower 52, and these rollers 521 respectively abut against the outer circumferential surface of cam 51 and the bottom surface of carrier 42. With this configuration, one end of follower 52 abutting against the outer circumferential surface of cam 51 is periodically pushed downward, causing follower 52 to oscillate, and the other end of follower 52 abutting against the bottom surface of carrier 42 pushes carrier 42 upward.

[0044] As shown in Figures 3 and 5, the adjustment mechanism 6 is connected to the housing 41 and can slide the housing 41 back and forth in the forward and backward direction A relative to the base 1, and is equipped with a worm 61, a worm wheel 62, a screw shaft 63, and a sliding block 64.

[0045] The worm 61 is arranged on the base 1 so as to be able to rotate, as shown in FIG.

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

[0047] As shown in Figures 3 and 5, the screw shaft 63 extends along the central axis of the worm wheel 62 and is arranged to pass through the worm wheel 62, so that it can rotate together with the worm wheel 62 and has a screw thread (not shown) formed on its outer circumferential surface.

[0048] As shown in Figures 3 and 5, the sliding block 64 is connected to the housing 41, arranged to surround the screw shaft 63, and has threads on the inside that engage with the threads formed on the outer surface of the screw shaft 63, so that it can move back and forth in the forward and backward direction A along the extension direction of the screw shaft 63 as the screw shaft 63 rotates.

[0049] More specifically, when the worm 61 is driven to rotate, the worm wheel 62 rotates along with the rotation of the worm 61, causing the screw shaft 63 fixed to the central axis of the worm wheel 62 to rotate together with the worm wheel 62. When the screw shaft 63 rotates, the sliding block 64 can move back and forth in the forward and backward direction A, and the housing 41 arranged on the sliding block 64 can move in the forward and backward direction A as the sliding block 64 moves.

[0050] The process of clamping and transporting a wire rod using the clamping device of this embodiment will be described below with reference to FIGS. 2, 5, 6 and 7. FIG.

[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 sliding mechanism 2 is slid along the feed direction D, and as the sliding mechanism 2 slides, the clamping mechanism 3 moves in the up-down direction B toward the main seat 21 of the sliding mechanism 2, i.e., upward.

[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), the main body portion 31 of the clamping mechanism 3 is spaced a certain distance from the sliding movement mechanism 2, so the wire is not clamped and the sliding 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 unit 34 of the clamping mechanism 3 moves from the first section 441 to the third section 443 via the second section 442 and comes into contact with the third section 443 (see FIG. 7), the roller unit 34 and the main body unit 31 are pushed upward by the relatively high third section 443 so as to approach the sliding movement mechanism 2. At this time, as shown in FIG. 6, the cam 51 drives the swing of the follower unit 52, which pushes the bottom surface of the carrier 42 upward, and as the carrier 42 moves upward, the guide plate 44 and the clamping mechanism 3 move upward, and the main body unit 31 of the clamping mechanism 3 approaches the main sheet 21 of the sliding movement mechanism 2 and clamps part of the wire rod in the clamping groove 211 together with the main sheet 21.

[0055] Third, after clamping the wire rod, the slide movement mechanism 2 continues to move in the feed direction D, and 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 portion of the wire rod, and the wire rod moves in the feed direction D as the slide movement mechanism 2 slides in the feed direction D.

[0056] Fourth, when the slide movement mechanism 2 reaches the target point (dead point), the cam 51 returns the follower part 52 downward. This causes the main body part 31 and the main seat 21 to no longer pinch a portion of the wire. The slide movement mechanism 2 simultaneously moves rearward. In this way, the main body part 31 moves away from the main seat 21, releasing the pinching of a portion of the wire, and the slide movement mechanism 2 returns to its original position, while the roller part 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 clamping of the wire), the wire can be conveyed in the feeding direction D.

[0058] In this embodiment, when the main body 31 of the clamping mechanism 3 and the main sheet 21 of the sliding movement mechanism 2 clamp a portion of the wire, the portion of the wire is within the V-shaped recess 311, so wires of different 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] The main body 31 of the clamping mechanism 3 and the sliding mechanism 2 move toward and away from each other in the vertical direction B to clamp or release the wire, so that even when clamping and transporting metal wires of different diameters, lengths, or specifications, clamping and transporting can be performed directly without replacing parts in the clamping device. This is convenient for users and has the effect of being highly versatile for wires.

[0060] Furthermore, even when manufacturing (forging) relatively long products, the wire rod can be clamped and transported without adding any additional parts to the clamping device, so no extra space is taken up in the manufacturing process, which improves the space utilization efficiency in the factory.

[0061] Furthermore, in this embodiment, the thrust of the multiple air cylinders 43 can be adjusted, so that the strength of the force with which the clamping mechanism 3 and control mechanism 4 rise to clamp the wire to the slide movement mechanism 2 can be adjusted. In this way, even if wires of different diameters are clamped, the wire will not be deformed. In addition, the sliding block 64 drives the movement of the control mechanism 4 in the feed direction D, thereby adjusting the position of the guide plate 44.

[0062] It should be noted that, in this embodiment, the clamping mechanism 3 clamps the wire by moving toward the sliding mechanism 2. However, this is not limited to this. In other embodiments, the sliding mechanism 2 may be designed in a different configuration. For example, a portion of the sliding mechanism 2 may extend below the clamping mechanism 3. In this case, the clamping mechanism between the clamping mechanism 3 and the sliding mechanism 2 is reversed. More specifically, when the roller unit 34 of the clamping mechanism 3 is in the third section 443, the main body 31 of the clamping mechanism 3 moves upward and away from the sliding mechanism 2, and does not clamp the wire. On the other hand, when the roller unit 34 moves from the third section 443 to the first section 441 via the second section 442, the main body 31 moves downward and approaches the sliding mechanism 2, and clamps the wire. In this way, the clamping device of this embodiment can adjust the clamping method and feed direction D for the wire by changing the settings of the sliding mechanism 2 according to needs.

[0063] In this embodiment, the main seat 21 of the sliding movement mechanism 2 is provided with one clamping groove 211, and one main body 31 of the clamping mechanism 3 is provided, so that one wire rod can be clamped and transported. However, this is not limited to this, and multiple main bodies 31 of the clamping mechanism 3 can be provided according to needs, and multiple clamping grooves 211 can be provided in the main seat 21, so that a corresponding number of wire rods can be clamped and transported.

[0064] In summary, the clamping device of the present invention does not require the separate provision of a feed roll, connecting shaft, or power source as in the prior art, and can clamp and transport wire by sharing the existing slide mechanism and power source.

[0065] Furthermore, even when clamping and transporting wire rods of different diameters or lengths, clamping and transporting can be performed directly without replacing parts in the clamping device, which is convenient for users and has the effect of being highly versatile for wire rods.

[0066] Furthermore, the clamping mechanism 3 and the sliding mechanism 2 clamp the wire to be clamped in a linear contact manner, thereby greatly reducing deformation of the wire. Furthermore, since the sliding mechanism 2 is incorporated into a sliding base structure for operating the linear movement of the punch in a forging machine, the clamping device according to the present invention can be applied to existing forging machines, and thus there is no need to incur costs for updating or replacing the forging machine.

[0067] Although numerous specific details are set forth above to provide a thorough understanding of the present invention, it will be apparent to one skilled in the art that one or more other embodiments may be practiced without these specific details.

[0068] While the preferred embodiments and variations of the present invention have been described above, the present invention is not limited to these and encompasses all modifications and equivalents as various configurations falling within the spirit and scope of the broadest interpretation. [Industrial Applicability]

[0069] The clamping device for a forging machine according to the present invention can clamp and transport wire rods of different lengths and diameters directly without replacing or adding parts, thereby improving space utilization efficiency and versatility for wire rods, and therefore has industrial applicability.
