Description

Technical Field

[0001] This utility model belongs to the field of screw processing technology, specifically relating to a wire cutting device for screw processing. Background Technology

[0002] A wire cutting device for screw processing is a mechanical device used to precisely cut metal wire to a preset length. This device typically uses motor-driven rollers or clamps to feed the wire into the cutting area at a constant speed, and then uses a high-speed rotating blade or a hydraulic / pneumatic device to drive the cutting tool to achieve the cutting of the wire. Wire cutting devices for screw processing not only improve production efficiency, significantly reduce manual operation, and increase production speed, but also ensure cutting accuracy and precisely control the wire length, meeting the needs of high-precision screw manufacturing. Wire cutting devices for screw processing are widely used in fastener manufacturing, the automotive industry, the electronics industry, building hardware, aerospace, and other fields.

[0003] Chinese Patent Publication No. CN213856824U discloses a wire cutting device for screw processing, belonging to the field of screw manufacturing technology. This utility model includes a base, a flipping plate, a slide rail, a wire carrier, a cutting cylinder, a top-support cylinder, and a wire reel conveying device. The flipping plate is movably mounted above the base, and a slide rail is provided above the flipping plate, fixedly connected to the surface of the flipping plate. Several wire carriers for positioning the wire are slidably mounted on the slide rail. A cutting cylinder for cutting the wire is located above the wire carrier. A support seat is located on the left side of the base, and a top-support cylinder is installed between the base and the support seat, movably connected to the flipping plate. A wire reel conveying device for transporting the wire is installed above the support seat. This utility model, by incorporating a sliding wire carrier inside the device, can cut wire to a fixed length, eliminating the need for high output precision required by conventional wire cutting devices, reducing manufacturing costs, and improving wire cutting efficiency.

[0004] In practical use, this utility model typically uses rollers or clamps to transport and straighten metal wires to ensure that the wires remain straight. However, the mechanical structure of existing screw processing wire cutting devices is often designed to be fixed, which means that they can only be used with metal wires of specific sizes. When processing needs shift to screws of other sizes, the adaptability of the device is significantly limited, which makes the applicability of screw processing wire cutting devices somewhat lacking. Utility Model Content

[0005] This utility model proposes a wire cutting device for screw processing to solve the problem that existing technologies are difficult to adapt to metal wires of different sizes and specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire cutting device for screw processing, comprising:

[0007] Workbench and processing box;

[0008] The mounting frame is located on one side of the upper end of the worktable, and the processing box is located on the other side of the upper end of the worktable. Positioning plates are provided on both sides inside the mounting frame.

[0009] Multiple positioning shafts are rotatably connected to the upper ends of two positioning plates. The upper end of the mounting frame is provided with multiple guide grooves that are adapted to the positioning shafts. The upper ends of the multiple positioning shafts are respectively provided with multiple guide grooves and each is provided with a guide wheel. The multiple guide wheels are arranged in an alternating manner.

[0010] A cutting slit is provided through the upper end of the processing box. A cylinder is provided on one side of the processing box, and a cutting blade is provided at the output end of the cylinder. The cutting blade is located at the bottom end of the cutting slit.

[0011] To flexibly adapt to metal wires of different sizes and specifications, a threaded rod is rotatably connected inside the mounting frame. The external threads on both sides of the threaded rod are arranged in opposite directions. Both positioning plates are provided with threaded holes that are adapted to the threaded rod. The threaded rod passes through the two threaded holes and is threadedly connected to the side wall of the threaded hole. One end of the threaded rod passes through one side of the mounting frame and extends to the outside.

[0012] In a preferred embodiment, the mounting frame is provided with multiple limiting rods, and both positioning plates are provided with limiting holes that are adapted to the limiting rods. The multiple limiting rods pass through the multiple limiting holes respectively and are slidably connected to the side walls of the limiting holes.

[0013] In a preferred embodiment, each of the two positioning plates is provided with a drive shaft at its bottom end, and the bottom ends of the plurality of positioning shafts respectively penetrate through the two positioning plates and are each provided with a first bevel gear. The outer sides of the two drive shafts are provided with a second bevel gear adapted to the first bevel gear, and the plurality of first bevel gears are respectively meshed with the plurality of second bevel gears.

[0014] In a preferred embodiment, a servo motor is provided on one side of the bottom of each of the two positioning plates, and one end of each of the two drive shafts is respectively located on the output end of the two servo motors.

[0015] In a preferred embodiment, the sidewall of the cutting opening is provided with multiple driving grooves, which are evenly distributed in a ring around the central axis of the cutting opening. Each of the multiple driving grooves is provided with an electric push rod, the output end of which extends into the cutting opening and is provided with a clamping plate.

[0016] In a preferred embodiment, an inclined guide plate is provided on one side of the processing box located at the bottom of the cutting opening, and a collection frame is provided on the upper part of the worktable located at the bottom of the guide plate.

[0017] To facilitate the cleaning of dust or impurities on the metal wire, rectangular grooves are further provided on both the upper and lower sides of the cutting opening. Multiple limiting springs are provided in both rectangular grooves. One end of each of the multiple limiting springs located on the same side is provided with a cleaning brush that is compatible with the rectangular groove. One end of each of the two cleaning brushes extends into the cutting opening.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, through the threaded rods with external threads arranged in opposite directions on both sides of the mounting frame, can synchronously drive the guide wheels on both sides to translate in opposite directions when the rods rotate, forming a dynamically adjustable guide channel. Combined with the clamping plates driven by multiple electric push rods, through independently controlled extension and retraction strokes, it can perform precise enveloping clamping on metal wires of different diameters and shapes. This dual-dimensional adjustment mechanism enables the device to quickly respond to changes in wire specifications, achieving stable fixation while maintaining the straightness of the wire, significantly expanding the compatibility range of the equipment with multi-specification wires, thereby greatly improving the flexibility and versatility of the screw processing production line;

[0020] 2. This utility model improves upon the multiple sets of limiting springs and two cleaning brushes installed inside the cutting opening. When the metal wire is conveyed through, the limiting springs use elastic pressure to dynamically center and position the wire. At the same time, their flexible contact characteristics can scrape off surface dust and deeply clean residual oxide scale, oil stains, or debris. This achieves seamless connection between wire surface pretreatment and the cutting process. No manual intervention is required during continuous production. It effectively avoids problems such as cutting surface defects, screw thread damage, or assembly accuracy deviations caused by residual impurities, ensuring the dimensional accuracy and surface quality of the screws, and significantly improving processing efficiency and product qualification rate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a wire cutting device for screw processing, comprising:

[0030] Workbench 1 and processing box 2;

[0031] The mounting frame 3 is located on one side of the upper end of the workbench 1, and the processing box 2 is located on the other side of the upper end of the workbench 1. Positioning plates 4 are provided on both sides inside the mounting frame 3.

[0032] Multiple positioning shafts 5 are rotatably connected to the upper ends of two positioning plates 4 respectively. The upper end of the mounting frame 3 is provided with multiple guide grooves that are adapted to the positioning shafts 5. The upper ends of the multiple positioning shafts 5 are respectively provided with multiple guide grooves and each is provided with a guide wheel 6. The multiple guide wheels 6 are arranged in an alternating manner.

[0033] A cutting opening 7 is provided through the upper end of the processing box 2. A cylinder 8 is provided on one side of the processing box 2. A cutting blade 9 is provided at the output end of the cylinder 8. The cutting blade 9 is located at the bottom end of the cutting opening 7.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, a threaded rod 10 is rotatably connected inside the mounting frame 3. The external threads on both sides of the threaded rod 10 are arranged in opposite directions. Both positioning plates 4 are provided with threaded holes that are compatible with the threaded rod 10. The threaded rod 10 passes through the two threaded holes and is threadedly connected to the side wall of the threaded hole. One end of the threaded rod 10 passes through one side of the mounting frame 3 and extends to the outside.

[0035] Its design allows the threaded rod 10 to rotate, causing the positioning plates 4 on both sides to move in opposite directions, thereby moving multiple positioning shafts 5 and multiple guide wheels 6. The spacing of the multiple guide wheels 6 can be flexibly adjusted to adapt to metal wires of different sizes and specifications, making the wire cutting device for screw processing more versatile.

[0036] Specifically, such as Figure 3 As shown, the mounting frame 3 is provided with multiple limiting rods 11 inside. Both positioning plates 4 are provided with limiting holes that are adapted to the limiting rods 11. The multiple limiting rods 11 pass through the multiple limiting holes respectively and are slidably connected to the side wall of the limiting holes. The multiple limiting rods 11, together with the multiple limiting holes, can limit the position of the two positioning plates 4 and prevent them from shifting when they move, thereby ensuring the accuracy of conveying and correcting the metal wire.

[0037] Specifically, such as Figure 2 and Figure 3 As shown, each of the two positioning plates 4 has a drive shaft 12 at its bottom end. The bottom ends of multiple positioning shafts 5 pass through the two positioning plates 4 respectively and each is provided with a first bevel gear 13. The outer sides of the two drive shafts 12 are provided with second bevel gears 14 that are adapted to the first bevel gears 13. The multiple first bevel gears 13 are meshed with the multiple second bevel gears 14 respectively. When the drive shaft 12 rotates, it will drive the multiple second bevel gears 14 to rotate. The multiple second bevel gears 14 will drive the multiple first bevel gears 13 to rotate respectively, thereby driving the multiple positioning shafts 5 and the multiple guide wheels 6 to rotate, which can drive the metal wire to move to one side of the processing box 2.

[0038] Specifically, such as Figure 3 As shown, each of the two positioning plates 4 has a servo motor 15 on one side of its bottom. The servo motor 15 is existing technology and will not be described in detail here. One end of each of the two drive shafts 12 is set on the output end of the two servo motors 15.

[0039] Specifically, such as Figure 4 As shown, the sidewall of the cutting opening 7 has multiple drive grooves, which are evenly distributed in a ring around the central axis of the cutting opening 7. Each drive groove is equipped with an electric push rod 16, which is existing technology and will not be described in detail here. The output ends of the multiple electric push rods 16 extend into the cutting opening 7 and are equipped with clamping plates 17. When the multiple electric push rods 16 are started, they will drive the multiple clamping plates 17 to move, so that they abut against metal wires of different sizes and specifications. This allows the wire cutting device for screw processing to be adapted to metal wires of different sizes and specifications.

[0040] Specifically, such as Figure 1 As shown, an inclined guide plate 18 is provided on one side of the processing box 2 located at the bottom of the cutting port 7, and a collection frame 19 is provided on the upper end of the workbench 1 located at the bottom of the guide plate 18. The inclined guide plate 18 can effectively discharge the processed screws into the collection frame 19.

[0041] Example 2:

[0042] Please see Figure 1-5 This utility model provides a wire cutting device for screw processing, comprising:

[0043] Workbench 1 and processing box 2;

[0044] The mounting frame 3 is located on one side of the upper end of the workbench 1, and the processing box 2 is located on the other side of the upper end of the workbench 1. Positioning plates 4 are provided on both sides inside the mounting frame 3.

[0045] Multiple positioning shafts 5 are rotatably connected to the upper ends of two positioning plates 4 respectively. The upper end of the mounting frame 3 is provided with multiple guide grooves that are adapted to the positioning shafts 5. The upper ends of the multiple positioning shafts 5 are respectively provided with multiple guide grooves and each is provided with a guide wheel 6. The multiple guide wheels 6 are arranged in an alternating manner.

[0046] A cutting opening 7 is provided through the upper end of the processing box 2. A cylinder 8 is provided on one side of the processing box 2. A cutting blade 9 is provided at the output end of the cylinder 8. The cutting blade 9 is located at the bottom end of the cutting opening 7.

[0047] Specifically, such as Figure 5 As shown, rectangular grooves are provided on both the upper and lower sides of the cutting opening 7. Multiple limiting springs 20 are provided in both rectangular grooves. One end of the multiple limiting springs 20 located on the same side is provided with the same cleaning brush 21 that is adapted to the rectangular groove. One end of both cleaning brushes 21 extends into the cutting opening 7.

[0048] Through its design, multiple limiting springs 20 can restrict the position of the two cleaning brushes 21, allowing the two cleaning brushes 21 to press against the outside of metal wires of different sizes and specifications, thereby conveniently cleaning the dust or impurities on the outside of the metal wires. This not only saves time and manpower for cleaning metal wires, but also ensures the quality of screw processing.

[0049] See Figure 1-5 When using the wire cutting device for screw processing, the threaded rod 10 is first rotated according to the size and specifications of the metal wire. The threaded rod 10 will drive the two positioning plates 4 to move in opposite directions. The two positioning plates 4 will drive multiple positioning shafts 5 and multiple guide wheels 6 to move respectively, so that the multiple guide wheels 6 can adapt to metal wires of different sizes and specifications. Then, the two servo motors 15 are started. The output ends of the two servo motors 15 will drive the two drive shafts 12 to rotate respectively. The two drive shafts 12 will drive multiple second bevel gears 14 to rotate respectively. The multiple second bevel gears 14 will drive multiple first bevel gears 13 to rotate respectively. The multiple first bevel gears 13 will drive multiple positioning shafts 5 and multiple guide wheels 6 to rotate respectively, thereby conveying the metal wire.

[0050] When cutting metal wire, it needs to be passed through the cutting opening 7 on the processing box 2. Multiple limiting springs 20 and two cleaning brushes 21 inside the cutting opening 7 can easily clean the dust or impurities on the surface of the metal wire. Then, multiple electric push rods 16 are activated. The output ends of the multiple electric push rods 16 will drive multiple clamping plates 17 to move, so that the multiple clamping plates 17 abut against the outside of the metal wire, thereby limiting its position. During the cutting process, the cylinder 8 needs to be activated. The output end of the cylinder 8 will drive the cutting blade 9 to move upward, so that the screw processing wire cutting device can cut metal wire of different sizes and specifications.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
