Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of processing and forming machines, and in particular to a processing and forming machine for irregular curved needles. Background Technology
[0002] With the improvement of people's living standards and the significant enhancement of health awareness, oral health care has gradually received widespread attention. Good oral hygiene is not only related to personal image, but also closely linked to overall health. Irregularly curved toothpicks stand out among many toothpicks, possessing significant advantages. Their irregular curved design is not arbitrary, but a scientific result derived from in-depth ergonomic research and extensive practical verification. This unique shape can better conform to the physiological curve of teeth, reaching deep into the interdental spaces that are difficult to reach with ordinary straight needles, thus cleaning the oral cavity more thoroughly.
[0003] While traditional processing methods can meet the personalized needs of product shapes to some extent, they suffer from serious inefficiency and are difficult to meet the needs of large-scale production. Moreover, traditional equipment occupies a lot of space, is complicated to operate, increases the intensity of manual labor, and reduces the convenience of use. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an irregularly curved needle processing and forming machine that facilitates the one-time completion of centering and limiting, first bending and second bending forming during the conveying of wire segments, improves linkage, reduces the complexity of manual operation, saves labor, and improves work efficiency.
[0005] This utility model discloses an irregular curved needle forming machine, comprising a first frame and a second frame, with the second frame positioned to the side of the first frame. It also includes a conveying device, a first linkage device, a second linkage device, a feeding device, an upper mold, a lower mold, a top block, a push rod, and a limiting block. The upper mold is mounted on the upper inner wall of the second frame, and the lower mold is mounted on the second frame via a swinging and rotating mechanism using the conveying device. The conveying device is used to transport wire segments. The lower mold and upper mold are positioned vertically opposite each other. The top block is positioned to the side of the lower mold via the first linkage device. The push rod is positioned on the second frame via the second linkage device. The limiting block is mounted on the outer wall of the upper mold, corresponding to the position of the push rod. The feeding device is positioned on the first frame and is used to transport and cut the wire. First, the wire is transported via the feeding device, and during transport, it is cut into wire segments. Then, the wire is further transported via the conveying device. The conveying device transports the wire segment between the upper and lower molds. An external drive unit rotates the lower mold back and forth, causing the upper and lower molds to work together to extrude and bend the wire segment into the desired shape. After the upper and lower molds have extruded and shaped the wire segment, the end of the wire segment is located to the side of the top block. At this point, the first linkage device moves the top block, causing it to bend the front end of the wire segment, thus forming an irregularly shaped bend. Before the wire segment enters the upper and lower molds, the movement of the lower mold drives the push rod to move horizontally back and forth via the second linkage device. Through the cooperation of the push rod and the limit block, the two ends of the wire segment are pushed, thus centering the wire segment. This achieves the effects of centering and limiting the wire segment during the conveying process, as well as the first bending and the second bending, improving the linkage of the equipment, reducing the complexity of manual operation, saving labor, and improving work efficiency.
[0006] Preferably, the conveying device includes a support shaft, a first sprocket, a first chain, a pressing wire, a conveying groove, and a screw. Two sets of support shafts are mounted on the outer wall of the second frame, and two sets of first sprockets are respectively mounted on the outer walls of the two sets of support shafts. The first chain is fitted onto the two sets of first sprockets, and the first chain has grooves equidistantly arranged circumferentially. One side of the lower mold is rotatably mounted on the outer wall of one set of support shafts. Both ends of the pressing wire are mounted on the outer wall of the second frame, with the bottom of the pressing wire contacting the top of the first chain. The conveying groove is located between the first frame and the second frame. Both ends of the screw are rotatably mounted on the first frame and the conveying groove, and the screw corresponds to the position of the first chain. The feeding device conveys the cut wire segments to the screw. The screw rotates and conveys the wire segments sequentially into the conveying trough. The wire segments in the conveying trough enter the groove of the first chain. The support shaft drives the first sprocket to rotate, causing the first sprocket to move the first chain circumferentially. After the first chain moves circumferentially, it continues to convey the wire segments. The push rod and the limiting block cooperate to center and position the wire segments on the first chain. When the wire segments on the first chain pass between the upper and lower molds, the upper mold, the lower mold and the top block cooperate to extrude and shape the wire segments. The pressing wire presses and limits the wire segments conveyed in the groove of the first chain, thereby improving the convenience of wire segment conveying and processing.
[0007] Preferably, the first linkage device includes a swing arm, a support wheel, an inclined support surface, and a first tension spring. The top of the swing arm is rotatably mounted on the second frame, the support wheel is rotatably mounted on the bottom of the swing arm, the inclined support surface is mounted on the outer wall of the lower mold, and the inclined support surface contacts the support wheel. The first tension spring is installed between the swing arm and the second frame, and the top block is installed on the outer wall of the swing arm. After the lower mold swings and rotates upward, it cooperates with the upper mold to extrude the wire segment into shape. At the same time, the lower mold drives the inclined support surface to move upward. After the inclined support surface moves upward, it pushes the swing arm through the support wheel, thereby causing the swing arm to drive the top block to swing and bend the front end of the wire segment into shape. After the lower mold swings and rotates downward, the first tension spring provides tension to the swing arm, causing the swing arm to drive the top block to swing and reset.
[0008] Preferably, the second linkage device includes a second sprocket, a second chain, and a second tension spring. Two sets of second sprockets are rotatably mounted on the second frame. The second chain is fitted onto the two sets of second sprockets. The left end of the second chain is connected to the outer wall of the second frame through the second tension spring, and the right end of the second chain is connected to the outer wall of the lower mold. A push rod is mounted on the outer wall of the second chain. After the lower mold swings and rotates downward, it pulls the second chain. After the second chain moves, it drives the push rod to move horizontally, so that the push rod cooperates with the limit block to center and position the wire segment conveyed on the first chain. After the lower mold swings and rotates upward, it pulls the second chain through the second tension spring, causing the push rod to move and reset.
[0009] Preferably, it also includes a horizontal arm, a stop block, and a connecting arm. The middle part of the horizontal arm is rotatably mounted on the second frame. The stop block is mounted on the front end of the horizontal arm and corresponds to the position of the first chain. The rear end of the connecting arm is mounted on the outer wall of the lower mold, and the front end of the connecting arm is in contact with the rear end of the horizontal arm. When the lower mold swings up and down, the connecting arm drives the horizontal arm to swing up and down. After the horizontal arm swings, it drives the stop block to swing up and down. Thus, the stop block blocks and limits the wire segment in the conveying groove, improving the convenience of a single wire segment entering one of the grooves of the first chain.
[0010] Preferably, the feeding device includes a wire feeding wheel, a shearing blade, a material tray, and a guide wheel. The wire feeding wheel is rotatably mounted on the first frame, the shearing blade is fitted onto the first frame, the guide wheel is mounted on the outer wall of the first frame, and the material tray is fitted onto the side of the first frame. The wire wound on the material tray is fed to the inside of the shearing blade through the guide wheel and the wire feeding wheel. The shearing blade cuts the wire into wire segments, which are then fed onto a screw. The screw rotates to feed the wire segments into the conveying trough.
[0011] Preferably, it also includes a grinding machine and a conveying block, which are installed together on the first frame; when the screw conveys the wire segment, it is limited by the conveying block to improve the smoothness of the wire segment conveying. At the same time, the grinding machine grinds the ends of the wire segment during the conveying process, thereby improving the convenience of processing irregularly bent needles and improving work efficiency.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the wire is conveyed by a feeding device, and the wire is cut into wire segments during the conveying process. Then, the wire segments are conveyed to the space between the upper and lower molds by a conveying device. The lower mold is driven by an external drive device to swing and rotate back and forth, so that the upper and lower molds cooperate to extrude and bend the wire segments into the required shape. After the upper and lower molds have extruded and shaped the wire segments, the ends of the wire segments are located on the side of the top block. At this time, the top block is moved by the first linkage device, so that the top block bends the front end of the wire segment, thereby forming an irregularly bent needle head. Before the wire segments enter the upper and lower molds, the movement of the lower mold is driven by the second linkage device to move the push rod back and forth horizontally. Through the cooperation of the push rod and the limit block, the two ends of the wire segments are pushed, so that the wire segments are centered and positioned. This achieves the effects of centering and limiting the wire segments during the conveying process, the first bending and the second bending, improving the linkage of the equipment, reducing the complexity of manual operation, saving labor, and improving work efficiency.
