[0001] This invention relates to the field of cutting equipment technology, specifically to a high-efficiency steel wire cutting device and cutting method, which is used for cutting the head of thick-diameter steel wire before welding. Background Technology

[0002] Steel wire butt welding machines are essential welding equipment for steel wire product manufacturers. They are commonly used for connecting the beginning and end of a coil of steel wire during the wire drawing process and for splicing broken wires after the drawing process. They are essential equipment for continuous production in manufacturing enterprises.

[0003] The production of thicker diameter (φ 8-20mm) steel wire, especially high-strength steel wire with a raw material strength reaching 1200MPa, requires the wire ends to be cut flat before welding to ensure better welding results. Currently, cutting machines on the market have low safety standards; the bottom of the cutting blade is unprotected, leaving it exposed and potentially causing injury. Furthermore, the cutting effect is poor, with sparks and smoke posing a hazard to operators. Summary of the Invention

Before cutting, the steel wire is clamped on three sides. The cutting machine is equipped with an openable protective component, which can greatly improve environmental hygiene and personal safety.

[0005] The objective of this invention is achieved as follows: A high-efficiency wire cutting device includes a wire cutting clamp and a protective wire cutting machine. The wire cutting clamp is fixed at a suitable position on a wire butt welding machine by means of a leveling pad, and the protective wire cutting machine is fixed on the right side of the wire cutting clamp by means of a bracket. The wire cutting fixture includes a fixture body, a bidirectional screw, a fixed clamping jaw, and two movable clamping jaws. The fixed clamping jaw is fixed to the top surface of the fixture body. The bidirectional screw is supported inside the fixture body. A rotating force-adding rod is provided at one end of the bidirectional screw that extends out of the fixture body. Flexible nuts are symmetrically connected to the screw portions on the front and rear sides of the bidirectional screw. Each flexible nut is hinged to a power arm. A pin is provided in the middle of the power arm. The pin is fixed to the fixture body. A movable clamping jaw is fixed at the top of each power arm. The fixed clamping jaw and the two symmetrical movable clamping jaws are distributed in a triangle. The protective wire cutting machine includes a support assembly, an electric cutting assembly, and an opening and closing protective assembly. The support assembly includes a support, which is hinged to the cutting machine support of the electric cutting assembly via a mounting shaft. The cutting machine body is fixed inside the cutting machine support, and the opening and closing protective assembly is installed on the outside of the cutting blade at the right output shaft end of the cutting machine body.

[0006] Preferably, the opening and closing protective assembly includes a fixed protective cover, a movable protective cover, and a connecting rod. The movable protective cover covers the fixed protective cover. The fixed protective cover has an opening at the front, and the movable protective cover has an opening at the rear. The centers of the cutting blade, the fixed protective cover, and the movable protective cover are on the same axis. The center of the left side of the fixed protective cover is fixed to the cutting machine body by a welded fixing ring, and the center of the right side is hinged to the movable protective cover. One end of the connecting rod is hinged to the upper part of the movable protective cover, and the other end is hinged to the support assembly.

[0007] Preferably, the central smooth rod portion of the bidirectional screw is provided with a limiting block, the limiting block and the fixed clamping jaw are arranged on the same center line, and the clamping body is provided with a slot for locking the limiting block located directly below the fixed clamping jaw.

[0008] Preferably, the power arm adopts a multi-segment structure, including an active arm and a driven arm. The active arm is hinged by a flexible nut, and the top of the active arm is inserted into the driven arm and then hinged by a pin. The movable clamping jaw is located at the top of the driven arm.

[0009] Preferably, the center of the right side of the fixed protective cover and the center of the right side of the movable protective cover are hinged by a rotating screw, and the rotating screw and the two hinge points of the connecting rod form a triangle.

[0010] Preferably, the bracket is further provided with a cutting spark collection box, which is correspondingly located below the openable protective component, and the front end of the cutting spark collection box is open.

[0011] Preferably, the mounting shaft is further provided with a limiting cam and a tightening nut. The limiting cam is located on the left side of the mounting sleeve at the bottom of the cutting machine bracket. The left side of the limiting cam is locked by the tightening nut. The cutting machine bracket is provided with a stroke control switch corresponding to the limiting cam.

[0012] Preferably, the fixed protective cover has a spacer on the right side corresponding to the rotating screw, and the spacer has a threaded hole. The movable protective cover has a sleeve on the right side corresponding to the rotating screw, and the rotating screw is fixed to the spacer after being inserted into the sleeve.

[0013] A cutting method using a high-efficiency steel wire cutting device, comprising the following steps: The steel wire is placed into the V-groove corresponding to the fixed clamping jaw of the wire cutting fixture. The head of the steel wire to be cut is located below the cutting disc of the protective wire cutting machine. Rotating the double screw causes the two flexible nuts to drive the corresponding power arm and its movable clamping jaw to clamp the steel wire around the pin. The steel wire is limited to the middle of the triangle formed by the fixed clamping jaw and the movable clamping jaw. Pressing down the cutting machine handle causes the cutting machine bracket to swing the cutting machine body, fixed protective cover, and travel control switch around the mounting shaft. At the same time, the movable protective cover rotates around the rotating screw under the action of the connecting rod, opening the bottom of both the fixed and movable protective covers simultaneously. The cutting blade is exposed in the gap at the bottom of the movable and fixed protective covers. During the swing, the travel control switch is pressed by the limit cam, forcing the travel control switch to conduct and be energized. The cutting machine body drives the cutting blade to rotate at high speed to cut the steel wire. After cutting, release the cutting machine handle, turn off the power to the cutting machine, rotate the double-headed screw in the opposite direction, move the clamping jaws to release the wire, and remove the wire.

[0014] The beneficial effects of this invention are: By setting three clamping jaws, with the fixed clamping jaw and two symmetrical movable clamping jaws arranged in a triangle, the bidirectional screw drives the two movable clamping jaws set at the front and rear to press down, ensuring the straightness of the steel wire while fixing the clamped steel wire in the middle of the triangle, thus achieving safe and reliable clamping of the steel wire. The steel wire will not slip out of the cutting fixture during the cutting process, greatly improving the safety of cutting. At the same time, since the head of the steel wire is clamped and fixed in the cutting fixture, the cutting effect is greatly improved, and the cut surface is flat. Before cutting, the opening and closing protective assembly fully encloses the cutting blade. When cutting is required, pressing down the cutting machine handle causes the cutting machine bracket to swing the cutting machine body, fixed protective cover, and travel control switch around the mounting shaft. At the same time, the movable protective cover rotates around the rotating screw under the action of the connecting rod, opening the bottom of both the fixed and movable protective covers simultaneously. The cutting blade is exposed in the gap at the bottom of the movable and fixed protective covers. During the swing, the travel control switch is pressed by the limit cam, forcing the travel control switch to conduct and become energized. The cutting machine body drives the cutting blade to rotate at high speed to cut the steel wire, improving operational safety. Equipped with a cutting spark collection box, it collects cutting sparks, reduces spark splashing, and greatly improves environmental hygiene. Attached Figure Description

The clamping body 1.1 is provided with a pin hole 1.1.2 corresponding to the pin 1.8. When the two flexible nuts 1.7 are close to or far from each other, the power arm 1.9 rotates around the pin 1.8, thereby realizing the action of the movable clamping jaws 1.4.

[0031] The power arm 1.9 adopts a multi-segment structure, including a driving arm 1.9.1 and a driven arm 1.9.2. The flexible nut 1.7 is hinged to the driving arm 1.9.1. The top of the driving arm 1.9.1 is inserted into the driven arm 1.9.2 and then hinged through the pin 1.8. The movable clamping jaw 1.4 is set at the top of the driven arm 1.9.2.

[0032] The limiting block 1.6 and the fixed clamping jaw 1.3 are arranged on the same center line. The clamping body 1.1 has a slot 1.1.3 located directly below the fixed clamping jaw 1.3 to lock the limiting block 1.6, ensuring that the two movable clamping jaws 1.4 are symmetrical.

[0033] The protective wire cutting machine 2 includes a support assembly 2.1, an electric cutting assembly 2.2, and a hinged protective assembly 2.3. The support assembly 2.1 includes a support 2.1.1, which is formed by bending a steel plate. A mounting shaft 2.1.2 is horizontally welded to the top left side of the support 2.1.1. The mounting shaft 2.1.2 connects to the cutting machine support 2.2.1 of the electric cutting assembly 2.2. A mounting sleeve is provided at the bottom of the cutting machine support 2.2.1 corresponding to the mounting shaft 2.1.2, allowing the electric cutting assembly 2.2 to rotate around the mounting shaft 2.1.2. A cutting machine body 2.2.2 is fixed inside the cutting machine support 2.2.1. The cutting machine body 2.2.2 is connected and fixed to the cutting machine support 2.2.1 by a fixing screw. The top of the fixing screw is connected to the cutting machine handle. A cutting blade 2.2.2.1 is provided at the right output shaft end of the .2. An openable protective assembly 2.3 is installed outside the cutting blade 2.2.2.1. The openable protective assembly 2.3 includes a fixed protective cover 2.3.1, a movable protective cover 2.3.2, and a connecting rod 2.3.3. The fixed protective cover 2.3.1 covers the cutting blade 2.2.2.1, and the movable protective cover 2.3.2 covers the fixed protective cover 2.3.1. The fixed protective cover 2.3.1 has an opening at the front, and the movable protective cover 2.3.2 has an opening at the rear. The left center of the fixed protective cover 2.3.1 is fixed to the cutting machine body 2.2.2 by a welded fixing ring 2.3.1.1, and the right center is hinged to the movable protective cover 2.3.2. The movable protective cover 2.3.2 has a clearance hole 2.3.2 on the left side corresponding to the fixing ring. 1. This design does not affect the fixation of the fixed protective cover 3.2 to the machine housing of the cutting machine body. The centers of the cutting blade 2.2.2.1, the fixed protective cover 2.3.1, and the movable protective cover 2.3.2 are on the same axis. The connecting rod 2.3.3 is located on the right side of the movable protective cover 2.3.2. One end of the connecting rod 2.3.3 is hinged to the upper part of the movable protective cover 2.3.2, and the other end is hinged to the bracket assembly 2.1. The right center of the fixed protective cover 2.3.1 and the right center of the movable protective cover 2.3.2 are hinged by a rotating screw 2.3.4. The rotating screw 2.3.4 and the upper and lower hinge points of the connecting rod 2.3.3 form a triangle, realizing the linkage opening and closing of the fixed protective cover 2.3.1 and the movable anti-slip cover 3.3.The fixed protective cover 2.3.1 has a spacer 2.3.1.2 on the right side corresponding to the rotating screw 2.3.4. The spacer 2.3.1.2 has a threaded hole. The movable protective cover 2.3.2 has a sleeve 2.3.2.2 on the right side corresponding to the rotating screw 2.3.4. After the rotating screw 2.3.4 is inserted into the sleeve 2.3.2.2, it is fixed with the spacer 2.3.1.2, thus realizing the hinge connection between the fixed protective cover 2.3.1 and the movable anti-slip cover 3.2.

[0034] The bracket 2.1.1 is also equipped with a spark collection box 2.1.3, which is positioned below the openable protective assembly 2.3. The front end of the spark collection box 2.1.3 is open, allowing sparks generated during cutting to enter and be collected. The rear end of the spark collection box 2.1.3 is detachable. When the spark collection box 2.1.3 is full, the fixing screws are removed, the rear end of the spark collection box is removed, and it is cleaned before use. A clearance groove 2.1.3.1 is also provided at the front end of the spark collection box 2.1.3 corresponding to the cutting blade 2.2.2.1 to prevent the cutting blade 2.2.2.1 from pressing down. When it collides with the cutting spark collection box 2.1.3, it can also position the steel wire to be cut, and quickly confirm the position of the cutting disc before cutting.

[0035] The mounting shaft 2.1.2 is also equipped with a limiting cam 2.1.4 and a tightening nut 2.1.5. The limiting cam 2.1.4 is located on the left side of the mounting sleeve of the cutting machine bracket 2.2.1, and the left side of the limiting cam 2.1.4 is locked by the tightening nut 2.1.5. The cutting machine bracket 2.2.1 is equipped with a stroke control switch 2.2.5 corresponding to the limiting cam 2.1.4. Under the joint action of the stroke control switch 2.2.5 and the limiting cam 2.1.4, the power supply of the cutting machine is controlled. When the cutting machine handle is pressed down, the cutting machine bracket 2.2.1 drives the stroke control switch 2.2.5 and the cutting machine body 2.2.2 to swing around the mounting shaft 2.1.2. The stroke control switch 2.2.5 swings... During operation, the cutting machine body 2.2.2 is pressed by the limit cam 2.1.4, which forces the stroke control switch 2.2.5 to be energized, and the cutting blade 2.2.2.1 rotates at high speed to cut the steel wire.

[0036] The bracket 2.1.1 is also provided with a cutting machine limit 2.1.6, which is used to adjust and control the lower limit position of the cutting machine body 2.2.2.

[0037] The movable protective cover 2.3.2 has a cowhide guard 2.3.5 on the front bottom side, which is used to block the sparks generated when cutting the steel wire.

[0038] Rotating the bidirectional screw 1.2 causes the two flexible nuts 1.7 to drive the corresponding power arms 1.9 and their movable clamping jaws 1.4 to open and close around the pin 1.8, thus clamping and releasing the steel wire. The fixed clamping jaw 1.3 and the two symmetrical movable clamping jaws 1.4 are arranged in a triangle. The fixed clamping jaw 1.3 is provided with a V-groove 1.3.1. The steel wire 5 to be clamped is placed into the V-groove to ensure the straightness of the steel wire. The bidirectional screw 1.2 drives the two movable clamping jaws 1.4 arranged in front and behind to press down, fixing the clamped steel wire in the middle of the triangle. The position of the clamped steel wire remains unchanged, thus achieving safe and reliable clamping of the steel wire. The steel wire will not slip out of the cutting fixture during the cutting process, which greatly improves the safety of cutting. At the same time, since the head of the steel wire is clamped and fixed in the cutting fixture, the cutting effect is greatly improved and the cutting surface is flat.

[0039] Before cutting, the opening and closing protective assembly fully encloses the cutting blade. When cutting is required, pressing down the cutting machine handle causes the cutting machine bracket 2.2.1 to drive the cutting machine body 2.2.2, the fixed protective cover 2.3.1, and the travel control switch 2.2.5 to swing around the mounting shaft 2.1.2. Simultaneously, the movable protective cover 2.3.2 rotates around the rotating screw 2.3.4 under the action of the connecting rod 2.3.3, thus opening the bottom of both the fixed protective cover 2.3.1 and the movable protective cover 2.3.2. The cutting blade 2.2.2.1 is exposed in the empty area at the bottom of the movable protective cover 3.1 and the fixed protective cover 3.2. During the swing, the travel control switch 2.2.5 is pressed by the limit cam 2.1.4, forcing the travel control switch 2.2.5 to conduct and become energized. The cutting machine body 2.2.2 drives the cutting blade 2.2.2.1 to rotate at high speed to cut the steel wire.
