Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing and processing, and in particular to a filament cutting device. Background Technology

[0002] Automotive parts include fine metal wires. When processing these wires, they need to be divided into multiple segments. To make it easier to segment the wires, they need to be heated appropriately. After heating, the wires are threaded into a cooling device. After threading the wires through one end, friction is generated between the wires and the cooling device to break the wires. However, if the wires cannot be broken in one go, repeated friction is required, which is cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a filament cutting device, which has the advantage of facilitating the cutting of metal filaments.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A filament cutting device includes a lower cavity and an upper cavity, both of which are semi-cylindrical. A rotating plate is hinged to the inner sidewall of the lower cavity. One end of the rotating plate has an integrally formed wedge-shaped piece with a beveled edge. An elastic element is disposed between the wedge-shaped piece and the bottom of the lower cavity. The other end of the rotating plate has an integrally formed L-shaped connecting piece with a vertical waist-shaped groove. A blade is hinged to the L-shaped connecting piece, and the sidewall surface of the blade has multiple waist-shaped grooves. A support is fixedly connected to the bottom of the cavity. The rotating plate and the blade are located on the side of the support. A limiting post is fixedly connected to the side wall of the support. The limiting post passes through one of the waist-shaped grooves and one of the waist-shaped grooves of the blade. The width of the waist-shaped groove is greater than the bottom diameter of the limiting post. Two horizontal guide posts are fixedly connected to the upper part of the support. The length of the upper cavity is less than the length of the lower cavity. The upper cavity is slidably connected to the lower cavity through a connector. A baffle is integrally formed at the lower opening of the upper cavity. The baffle is close to the wedge-shaped plate of the rotating plate.

[0006] Using the above technical solution, when the upper cavity is away from the support, the end of the upper cavity contacts the push block of the U-shaped tie rod, the baffle of the upper cavity contacts the wedge of the rotating plate, and exerts a force on the wedge to make the wedge rotate downward, thereby making the elastic element connected to the wedge elastic, and the blade connected to the rotating plate is lifted up, so that there is a gap between the blade and the bottom of the lower cavity. Part of the waist-shaped groove II on the blade is located above the cavity opening. The metal wire is passed through the waist-shaped groove II of the blade, and the upper cavity is moved to the upper part of the support through the connector. The baffle of the upper cavity separates from the wedge, the elastic element releases its elasticity and pushes the rotating plate to rotate. The rotating plate drives the blade to rotate. The inner wall of the waist-shaped groove II of the blade exerts pressure and friction on the metal wire, thereby cutting the metal wire. At the same time, the upper cavity moves to the upper part of the support. After the metal wire is cut, it pushes the U-shaped tie rod and the upper cavity back to the original position. The baffle of the upper cavity presses the wedge again, the rotating plate rotates back, and the blade is lifted.

[0007] Preferably, support plates are integrally formed on both sides of the upper opening of the lower cavity. The support plates have slots on the side facing the outside of the lower cavity. The connector is a U-shaped pull rod. The two arms of the U-shaped pull rod are respectively embedded in the slots of the two support plates. The U-shaped pull rod is slidably connected to the support plates. Push plates are integrally formed on both ends of the U-shaped pull rod. Support plates are fixedly connected to both sides of the lower opening of the upper cavity. The length of the support plates is less than the length of the upper cavity. The support plates have slots on the side facing the middle of the upper cavity. The two arms of the U-shaped pull rod are respectively embedded in the slots of the two support plates. The U-shaped pull rod is slidably connected to the support plates.

[0008] Using the above technical solution, pulling the U-shaped pull rod causes the pusher plate of the U-shaped pull rod to push the upper cavity closer to the support. The baffle plate of the upper cavity separates from the wedge plate, and the elastic element releases its elasticity to push the rotating plate to rotate. The rotating plate drives the blade to rotate, and the inner wall of the waist-shaped groove of the blade generates pressure and friction on the metal wire, thereby cutting the metal wire. At the same time, the upper cavity moves to the upper part of the support. After the metal wire is cut, the U-shaped pull rod and the upper cavity are pushed back to their original positions.

[0009] Preferably, the bottom of the lower cavity is provided with a groove, the spring is embedded in the groove, and a protrusion is integrally formed on the bottom side of the wedge-shaped plate, the protrusion passing through the upper opening of the spring.

[0010] Using the above technical solution, the baffle of the upper cavity contacts the wedge-shaped plate of the rotating plate and exerts a force on the wedge-shaped plate, causing the wedge-shaped plate to rotate downward. This causes the elastic element connected to the wedge-shaped plate to become elastic, and at the same time the blade connected to the rotating plate is lifted up. The baffle of the upper cavity separates from the wedge-shaped plate, and the elastic element releases its elasticity to push the rotating plate to rotate. The rotating plate drives the blade to rotate.

[0011] Preferably, the inner side wall of the lower cavity is threaded with a horizontal bolt, and the rotating plate is rotatably connected to the bolt.

[0012] Using the above technical solution, the rotating piece rotates around the bolt.

[0013] Preferably, the limiting post is bolt two, which is threaded to the side wall of the support. Bolt two passes through the waist-shaped groove one of the connecting piece and one of the waist-shaped grooves two of the blade. The connecting piece and the blade are located between the tail of the bolt and the side wall of the support.

[0014] By adopting the above technical solution, the tail cap of bolt two can block the connecting piece and the blade, preventing the blade from detaching from the bolt.

[0015] Preferably, the device also includes a guide mechanism, which is connected to the two side walls of the lower cavity and the support respectively. The guide mechanism is a folded, wave-shaped piece, and the groove formed by the folding is a guide wire groove.

[0016] Using the above technical solution, the metal wire passes through the guide grooves of the guide mechanism on both sides of the lower cavity and the support, keeping the metal wire straight and enabling it to be cut more effectively. Attached Figure Description

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 A filament cutting device includes a lower cavity 1 and an upper cavity 2, both of which are semi-cylindrical. A horizontal bolt 15 is threaded onto the inner side wall of the lower cavity 1. A rotating plate 3 is rotatably connected to the bolt 15. A wedge-shaped plate 4 is integrally formed at one end of the rotating plate 3. The wedge-shaped plate 4 has a bevel. A spring 13 is fixedly connected between the wedge-shaped plate 4 and the bottom of the lower cavity 1. A protrusion 14 is integrally formed on the bottom side of the wedge-shaped plate 4. A groove is opened at the bottom of the lower cavity 1, in which the spring 13 is embedded. The protrusion 14 passes through the opening at the upper end of the spring 13.

[0028] See Figure 5 , Figure 6 , Figure 7 and Figure 8 The other end of the rotating plate 3 is integrally formed with an L-shaped connecting plate 5. The L-shaped connecting plate 5 has a vertical waist-shaped groove 6. The L-shaped connecting plate 5 is hinged to a blade 7. The side wall surface of the blade 7 has multiple waist-shaped grooves 8. One of the waist-shaped grooves 8 is aligned with the waist-shaped groove 6. The bottom of the lower cavity 1 is fixedly connected to a support 9. The rotating plate 3 and the blade 7 are located on the side of the support 9. The side wall of the support 9 is threaded with a bolt 16. The bolt 16 passes through the aligned waist-shaped groove 6 and waist-shaped groove 8. The width of the waist-shaped groove 6 is greater than the diameter of the bolt 16, so that the bolt does not restrict the rotation of the rotating plate 3.

[0029] See Figure 1 , Figure 3 and Figure 4Guide mechanisms 17 are attached to the upper part of the support 9 and the two side walls of the lower cavity 1. The guide mechanism 17 is a folded wave-shaped piece, and the groove formed by the folding is a guide wire groove. The upper part of the two side edges of the lower cavity 1 is integrally formed with support piece 1, and also includes a cover plate and a U-shaped pull rod 11. The two sides of the cover plate are fixedly connected to the support pieces on both sides of the opening of the lower cavity 1. The cover plate is located on the upper side of the support 9. The wedge-shaped piece 4 passes through the cover plate. The two ends of the lower cavity 1 are fixedly connected with end cap 1 and end cap 2. End cap 1 is circular and located at the end of the lower cavity 1 near the cover plate. End cap 2 is semi-circular and located at the end of the lower cavity 1 near the support 9. The support piece 1 has a slot on the side facing the outside of the lower cavity 1. The two arms of the U-shaped pull rod 11 are respectively embedded in the slots of the two support pieces 1. The U-shaped pull rod 11 is slidably connected to the support piece 1. The two ends of the U-shaped pull rod 11 are integrally formed with push pieces 12, which are close to the cover plate.

[0030] See Figure 1 , Figure 2 and Figure 5 The length of the upper cavity 2 is less than the length of the lower cavity 1. The upper cavity 2 is located above the cover plate. Support plates 2 are fixedly connected to both sides of the lower opening of the upper cavity 2. The length of the support plates 2 is less than the length of the upper cavity 2. A slot is opened on the side of the support plates 2 facing the middle of the upper cavity 2. The two arms of the U-shaped pull rod 11 are respectively embedded in the slots of the two support plates 2. The U-shaped pull rod 11 is slidably connected to the support plates 2. A baffle 10 is integrally formed at the lower opening of the upper cavity 2. The baffle 10 is close to the wedge-shaped piece 4 of the rotating piece 3. The baffle 10 is located above the cover plate.

[0031] Working principle: When the upper cavity 2 is away from the support 9, the end of the upper cavity 2 contacts the push block of the U-shaped pull rod 11. The baffle 10 of the upper cavity 2 contacts the wedge 4 of the rotating plate 3 and exerts a force on the wedge 4, causing the wedge 4 to rotate downward and compress the spring 13. The blade 7 connected to the rotating plate 3 is lifted up, creating a gap between the blade 7 and the bottom of the lower cavity 1. A part of the waist-shaped groove 8 on the blade 7 is located above the cavity opening. The metal wire is passed through the waist-shaped groove 8 of the blade 7, as well as the wire guide groove of the guide mechanism 17 on the support 9 and the side wall of the lower cavity 1. Pulling the U-shaped lever 11 causes the pusher plate 12 of the U-shaped lever 11 to push the upper cavity 2 closer to the support 9. The baffle plate of the upper cavity 2 separates from the wedge plate 4. The spring 13 rebounds and pushes the rotating plate 3 to rotate. The rotating plate 3 drives the blade 7 to rotate. The inner wall of the waist-shaped groove 8 of the blade 7 generates pressure and friction on the metal wire, thereby cutting the metal wire. At the same time, the upper cavity 2 moves to the upper part of the support 9. After the metal wire is cut, it pushes the U-shaped lever 11 and the upper cavity 2 back to their original positions. The baffle plate 10 of the upper cavity 2 presses down on the wedge plate 4 again. The rotating plate 3 rotates back, and the blade 7 is lifted.
