Description

Technical Field

[0001] This utility model relates to the field of manufacturing and processing technology, specifically to a wire cutting fixture. Background Technology

[0002] In the manufacturing sector, the shearing of rod-shaped wires is a crucial step in the production process, widely used in industries such as electronics, automotive, and precision machinery. Traditional wire shearing fixtures are prone to producing burrs, flash, or surface damage on the cut edges, which not only affects the product's appearance quality but may also cause assembly difficulties, functional failures, or even safety hazards due to burr residue. Utility Model Content

[0003] The purpose of this utility model is to provide a wire-cutting fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows.

[0005] A wire-cutting fixture includes a base, a lower blade holder mounted on the top of the base, a pad mounted on the upper surface of the lower blade holder, a V-groove formed on the surface of the pad, a lower V-shaped blade mounted on the rear side of the lower blade holder, and a baffle provided on the top of the base behind the lower V-shaped blade. An upper V-shaped blade is mounted on the top of the base via a cutting mechanism.

[0006] It can be seen that the V-shaped groove on the pad provides positioning for the rod-shaped wire, preventing it from sliding to both sides during cutting and ensuring that the end face is flush with the baffle. The lower and upper V-shaped blades form a symmetrical clamp for the rod-shaped wire, further preventing the wire from sliding. The V-shaped cutting edge gradually cuts in from both sides to disperse stress, thereby avoiding edge tensile stress tearing and inhibiting burr formation, thus improving the quality of wire cutting.

[0007] Furthermore, the shearing mechanism includes four columns installed at the four corners of the top of the base. A top plate is mounted on the top of the four columns, and a cylinder is mounted on the top of the top plate. A lifting plate is mounted on the end of the cylinder's extension / retraction mechanism, and the upper V-shaped blade is mounted on the bottom of the lifting plate via an upper blade holder. When the cylinder is activated, it pushes the lifting plate downward, which in turn drives the upper V-shaped blade to shear the rod-shaped wire.

[0008] Furthermore, the lifting plate is slidably mounted on four columns via linear bearings. This ensures precise cutting of the rod-shaped wire by the upper V-shaped blade, improving the cutting quality.

[0009] Furthermore, a retaining ring is installed on one of the columns to limit the descent height of the lifting platform and prevent it from colliding with the retaining plate due to excessive travel.

[0010] Furthermore, elongated holes are provided on both sides of the bottom of the baffle. The baffle is bolted to the base, and a scale line is provided on the top of the base. A pointer is provided on the baffle. This allows for adjustment of the cutting length of the rod-shaped wire and achieves the purpose of fixed-length cutting.

[0011] Furthermore, the base has an internal collection drawer, and the top of the base has a discharge port that connects to the collection drawer. This enables unified collection of waste materials, facilitating recycling.

[0012] Furthermore, a transparent protective plate is installed on the top of the base, with a material inlet hole on the plate. This effectively avoids mechanical injuries caused by operational errors, ensuring good safety.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model uses the V-shaped groove on the pad to position the rod-shaped wire, preventing it from sliding to both sides during cutting and ensuring that the end face is flush with the baffle. The lower and upper V-shaped blades form a symmetrical clamping of the rod-shaped wire, further preventing the wire from sliding. The V-shaped cutting edge gradually cuts in from both sides to disperse stress, thereby avoiding edge tensile stress tearing and suppressing burr formation, thus improving the quality of wire cutting.

[0015] 2. This utility model allows for adjustment of the baffle's installation position through the elongated hole and bolts, thereby enabling adjustment of the cutting length of the rod-shaped wire and achieving fixed-length cutting. Furthermore, the inclusion of scale lines and pointers provides a scale reference, allowing for precise adjustment of the baffle's position and ensuring product consistency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-6 As shown, a wire cutting fixture includes a base 1, a lower blade holder 101 mounted on the top of the base 1, a pad 102 mounted on the upper surface of the lower blade holder 101, a V-groove formed on the surface of the pad 102, a lower V-shaped blade 103 mounted on the rear side of the lower blade holder 101, and a baffle 104 disposed on the top of the base 1 and behind the lower V-shaped blade 103. An upper V-shaped blade 105 is mounted on the top of the base 1 via a cutting mechanism 2.

[0020] During use, the worker places the rod-shaped wire into the V-shaped groove on the pad 102 and makes its end abut against the baffle 104. At this time, the bottom of the rod-shaped wire contacts the lower V-shaped blade 103. Then, the upper V-shaped blade 105 is driven down by the shearing mechanism 2. During the shearing process, the lower V-shaped blade 103 and the upper V-shaped blade 105 form a symmetrical clamp on the rod-shaped wire, which further prevents the wire from slipping. The V-shaped cutting edge gradually cuts in from both sides to disperse the stress, thereby avoiding edge tensile stress tearing and inhibiting burr generation, thus improving the quality of wire cutting.

[0021] Preferably, the shearing mechanism 2 includes four columns 201 installed at the four corners of the top of the base 1. A top plate 202 is installed on the top of the four columns 201. A cylinder 203 is installed on the top of the top plate 202. A lifting plate 204 is installed at the end of the telescopic end of the cylinder 203. The upper V-shaped blade 105 is installed at the bottom of the lifting plate 204 through the upper blade holder 106.

[0022] When the cylinder 203 is activated, it pushes the lifting plate 204 downward, which can drive the upper V-shaped blade 105 to cut the rod-shaped wire.

[0023] Preferably, the lifting plate 204 is slidably mounted on the four columns 201 via linear bearings 206.

[0024] The column 201 not only provides support for the top plate 202, but also provides linear guidance for the lifting plate 204 through the linear bearing 206, ensuring the precise cutting of the rod-shaped wire by the upper V-shaped blade 105 and improving the cutting quality.

[0025] Preferably, a retaining ring 205 is installed on one of the columns 201.

[0026] The lowering height of the lifting plate 204 is limited by the retaining ring 205 to prevent it from colliding with the baffle 104 due to excessive travel.

[0027] Preferably, elongated holes 3 are provided on both sides of the bottom of the baffle 104. The baffle 104 is installed on the base 1 by bolts 301. The top of the base 1 is provided with scale lines 302, and the baffle 104 is provided with pointers 303.

[0028] The installation position of the baffle 104 can be adjusted by setting the elongated hole 3 and the bolt 301, thus adjusting the cutting length of the rod-shaped wire and achieving the purpose of fixed-length cutting. In addition, with the setting of the scale line 302 and the pointer 303, a scale reference can be provided, and the position of the baffle 104 can be precisely adjusted to ensure product consistency.

[0029] Preferably, the base 1 has a material collection drawer 4 inside, and the top of the base 1 has a discharge port 401 that communicates with the material collection drawer 4.

[0030] The cut portion of the rod-shaped wire falls through the gap between the baffle 104 and the lower V-shaped blade 103 and passes through the discharge port 401 into the collection drawer 4, realizing the unified collection of waste materials and facilitating recycling.

[0031] Preferably, a transparent protective plate 5 is provided on the top of the base 1, and a material inlet hole 501 is provided on the transparent protective plate 5.

[0032] When operating the equipment, workers insert the rod-shaped material through the feed hole 501 for shearing, which effectively avoids mechanical injuries caused by operational errors and ensures good safety.
