Description

Technical Field

[0001] The invention relates to a feeding device, in particular to a feeding device used for conveying metal wires in a forging part forming machine. Background Art

[0002] The forming machine generally used for forging continuously feeds bundled metal wires to continuously forge multiple products. The forming machine continuously feeds the metal wires through a feeding device, which is usually driven by a cam connecting rod mechanism driven by a power source such as a motor or a pneumatic cylinder, thereby rotating the feeding wheels in pairs. The feeding wheels rotate at the same speed and in opposite directions, so that the metal wires can be fed from back to front through friction, so that the metal wires can be transported according to the required stroke.

[0003] However, the feed wheel needs to be additionally provided with a connecting shaft and a power source, and attention needs to be paid to the stroke design and interference issues. The mechanism configuration is difficult and the cost of electronic control is increased. In addition, since the gap between the feed wheels is a fixed value, it can only correspond to metal wires of the same wire diameter. When metal wires of different wire diameters are to be forged, the feed wheel needs to be removed and replaced with a feed wheel with a suitable wheel diameter so that the gap can correspond to the wire diameter. The replacement is time-consuming and labor-intensive and has low versatility. If the forging process of longer products is to be used, additional feed wheels need to be installed, which increases the size of the machine and also requires the removal and replacement of components.

[0005] The feeding device of the forging part forming machine of the present invention is suitable for conveying metal wire; it is characterized in that: the feeding device includes a base defining a guide groove extending along the feeding direction, a slide arranged in the guide groove, a clamping mechanism, and a power source that can be controlled to drive the slide to reciprocate relative to the base along the feeding direction, the slide defines a clamping groove, a front guide hole connected to the clamping groove and extending forward along the feeding direction, and a rear guide hole connected to the clamping groove and extending rearward along the feeding direction, the rear guide hole, the clamping groove, and the front guide hole allow the metal wire to extend through in sequence from back to front, and the clamping mechanism is arranged corresponding to the clamping groove, and can be controlled to clamp the part of the metal wire located in the clamping groove.

[0018] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0019] See also Figure 1 and Figure 2 An embodiment of the feeding device of the forging part forming machine of the present invention comprises a base 1, a slide 2 slidably disposed on the base 1, a clamping mechanism 3 disposed on the base 1 and located below the slide 2, and a power source 4 connected to the slide 2. The base 1 defines a guide groove 11 extending along a feeding direction A. The slide 2 includes a main seat 21 slidably embedded in the guide groove 11, and a guide mechanism 22 disposed in the main seat 21.

[0020] See also Figure 2 , Figure 3 ,and Figure 4The guide mechanism 22 comprises a tube seat 221 fixed in the main stand 21 and defining a material clamping groove 23 opening downward, a front conduit 222 inserted in the tube seat 221 and penetrating the main stand 21 forward along the feeding direction A, a rear conduit 223 inserted in the tube seat 221 and penetrating the main stand 21 backward along the feeding direction A, and a calibration piece 224 embedded in the main stand 21 and located in front of the front conduit 222 along the feeding direction A. The front conduit 222 surrounds a front guide hole B connected to the material clamping groove 23, and the rear conduit 223 surrounds a rear guide hole C connected to the material clamping groove 23. The tube seat 221 has a fixing portion 225 fixed to the main stand 21, a front connecting portion 226 protruding downward from the fixing portion 225 and for the front conduit 222 to be inserted, and a rear connecting portion 227 protruding downward from the fixing portion 225 and spaced from the front connecting portion 226 along the feeding direction A and for the rear conduit 223 to be inserted. The fixing portion 225, the front connecting portion 226, and the rear connecting portion 227 cooperate to define the clamping groove 23. The fixing portion 225 blocks a portion of the front guide hole B along the feeding direction A. The calibration piece 224 surrounds a centering hole 228 whose central axis extends along the feeding direction A. The central axis of the centering hole 228 and the central axis of the front guide hole B are parallel lines to each other. The centering hole 228 has a perforated section D with a fixed aperture and far away from the leading hole B, and an inclined guide section E connected to the perforated section D and adjacent to the leading hole B, with the aperture gradually increasing from front to back.

[0021] See also Figure 1 , Figure 2 ,and Figure 4In this embodiment, the clamping mechanism 3 includes an outer shell seat 31 slidably disposed on the base 1 along the feeding direction A, an inner platform 32 movably accommodated in the outer shell seat 31, four pneumatic cylinders 33 disposed on the inner platform 32, a guide plate 34 whose bottom surface is connected to the pneumatic cylinder 33, and a clamping seat 35 pressed against the guide plate 34 and partially extending upward into the clamping groove 23. The guide plate 34 has a first stroke section 341, a connecting section 342 connected to the first stroke section 341, and a second stroke section 343 connected to the connecting section 342. The top surface of the second stroke section 343 is higher than the top surface of the first stroke section 341 along the height direction. The bottom end of the clamping seat 35 is provided with a roller and is in rolling contact with the guide plate 34. When the clamping seat 35 moves from the first stroke section 341 to the second stroke section 343, the clamping seat 35 is pushed upward and approaches the fixing portion 225. It should be noted that the clamping mechanism 3 may also adopt different structural designs and is not limited to the above-mentioned exemplary structure. In this embodiment, the slide 2 can be integrated into a general forging component forming machine and used to drive the linear movement of the punch on the slide structure, so the power source 4 and the slide structure are the same power source. Also, since this embodiment is a mechanical linkage structure, the structure is simple and the electronic control adjustment method can be simplified, thereby reducing the time and cost of electronic control adjustment.

[0022] See also Figure 2 , Figure 4 ,and Figure 5 The feeding steps of this embodiment are described below. First, the front end of a metal wire is passed through the rear guide hole C, the clamping groove 23 and the front guide hole B in sequence from back to front along the feeding direction A. Then, the slide 2 is driven by the power source 4 to reciprocate relative to the base 1 along the feeding direction A. When the clamping seat 35 is Figure 2 When the clamp seat 35 is pressed against the first travel section 341 as shown, since the clamp seat 35 is far away from the fixing portion 225, it will not clamp the metal wire, so that the slide 2 can slide relative to the metal wire without moving the metal wire. Figure 5When the second stroke section 343 is pressed against the second stroke section 343, the higher second stroke section 343 will push the clamp seat 35 upward to approach the fixing portion 225. At this time, the bottom surface of the inner platform 32 will be pushed upward through the cam link mechanism F or other mechanisms, so that the clamp seat 35 cooperates with the fixing portion 225 to clamp the portion of the metal wire located in the clamping groove 23. During the movement of the clamp seat 35 along the second stroke section 343, the clamp seat 35 and the fixing portion 225 will continue to clamp the metal wire, and the metal wire can be pulled forward along the feeding direction A in coordination with the movement of the slide 2. When the slide 2 moves to the dead point position, the power source 4 will reversely drive the slide 2 to reset, and at the same time, the cam link mechanism F or other mechanisms will reset downward, so that the clamp seat 35 is released and no longer clamps the metal wire. By repeating the above steps, the metal wire can be continuously fed along the feeding direction A in a clamping and releasing action.

[0023] It should be noted that in order to prevent the metal wire from being misaligned when being threaded at the beginning, the calibration piece 224 is provided in front of the front guide tube 222. Through the design of the oblique guide section E gradually closing forward from wide to narrow, the front end of the metal wire can realign its central axis under the guidance of the oblique guide section E. In addition, since the clamping method of the present invention is achieved by clamping the metal wire up and down through the clamping seat 35 and the fixing portion 225, it can be applied to all metal wires with a wire diameter smaller than the front guide hole B and the rear guide hole C, and has a higher convenience without the need to replace parts. Although this embodiment takes the example of a guide mechanism 22 provided on the main stand 21 to convey a metal wire, in fact, multiple guide mechanisms 22 can also be provided on the main stand 21 as needed, so as to convey multiple metal wires at a time. In this embodiment, the length limit of the product is determined based on the displacement stroke of the slide 2, and the length of the product can never exceed the displacement stroke of the slide 2. Therefore, in this embodiment, the forging process of longer products can be fed without adding or replacing components.

[0024] In summary, the present invention does not need to set up a feeding wheel, a connecting rod feeding mechanism, and other power sources, but is integrated into the existing slide mechanism to share the power source. This can avoid delay problems and interference problems caused by improper adjustment, and there is no need to add components to correspond to the forging process of longer products, which can greatly save the installation space. At the same time, it can also be used for metal wires of different wire diameters to improve versatility, so the purpose of the present invention can indeed be achieved.
