Description

Technical Field

[0001] This utility model relates to the field of abrasive wire production technology, specifically to a cutting device for abrasive wire production. Background Technology

[0002] In the existing device, when cutting abrasive wire, the cylinder is opened, and the cylinder drives the lever, so that the pressure plate presses the wire onto the clamping table. After the clamping devices on both sides of the through hole clamp the wire on both sides, the other two oppositely arranged cylinders are opened. The extension and retraction ends of the other two cylinders push the upper blade and the lower blade respectively, so that the upper blade and the lower blade close together to cut the wire.

[0003] Abrasive wire cutting does not require extremely high precision and cutting force. It only requires ensuring a uniform distribution of force during the cutting process to avoid uneven force leading to incomplete or broken abrasive wire. The cylinder system mentioned above is usually expensive and requires an air supply and air pressure control equipment, which increases the overall complexity and maintenance cost of the system. Moreover, two cylinders are more likely to fail than a single cylinder. When one of the two cylinders fails to work properly, it will cause uneven closing of the upper and lower blades, resulting in ineffective cutting of the wire. Furthermore, a malfunctioning cylinder will cause one side of the blade to fail to fully press the wire, resulting in incomplete or unclean cutting. Therefore, a cutting device for abrasive wire production is needed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Abrasive wire cutting does not require extremely high precision or cutting force. It only requires ensuring a uniform distribution of force during the cutting process to prevent uneven force from causing the abrasive wire to break or resulting in incomplete or unclean cutting. The aforementioned cylinder system is typically expensive and requires an air supply and pressure control equipment, increasing the overall system complexity and maintenance costs. Furthermore, two cylinders are more prone to failure than a single cylinder. When one of the two cylinders malfunctions, it leads to uneven closure of the upper and lower blades, resulting in ineffective wire cutting. A malfunctioning cylinder also prevents one side of the blade from fully pressing the wire, resulting in unclean or incomplete cutting. Please refer to [link to relevant documentation]. Figures 1-3 This embodiment provides a cutting device for abrasive filament production, including a base plate 1. A plurality of rotating wheels 2 are disposed on the top of the base plate 1. Each of the rotating wheels 2 has a wire feeding groove 3 on its outer wall. The inner wall of the wire feeding groove 3 is provided with a flocked rubber plate to reduce abrasive filament wear. The flocked rubber plate is a plate-like structure made of rubber with a flocked upper surface. When the abrasive filament is placed into the wire feeding groove 3, it rubs against the inner wall of the wire feeding groove 3 during the feeding process. The flocked rubber plate, through its special material and structural design, can effectively mitigate this friction, reducing abrasive filament wear. It also provides a buffering effect during friction, allowing the abrasive filament to experience smoother friction when in contact with the flocked rubber plate during feeding, thus reducing direct wear.

[0022] like Figures 1-3As shown, the cost of the existing device cylinder system is usually high, and the gas source supply and air pressure control equipment are needed, which increases the overall complexity and maintenance cost of the system, and the probability of damage of two cylinders is higher than that of a single cylinder. When one of the two cylinders cannot work normally, it will cause uneven closing of the upper and lower blades, resulting in ineffective cutting of the steel wire, and the failed cylinder will cause one side of the blade to be unable to completely press the steel wire, resulting in incomplete cutting. In order to reduce the risk and cost and increase the integrity of abrasive wire cutting, the following settings are made. The top of the base plate 1 is provided with a power mechanism 4 for driving a plurality of rotating wheels 2 to rotate synchronously. The power mechanism 4 includes a motor 41 fixed on the top of the base plate 1, and a rotating shaft 42 is fixed on the output end of the motor 41. A plurality of rotating wheels 2 are transversely and equidistantly fixed on the outer wall of the rotating shaft 42. Starting the motor 41 drives the output end to drive the rotating shaft 42 to rotate, and the rotating shaft 42 drives the plurality of rotating wheels 2 to rotate, which drives the cutting mechanism 5 arranged in the grooves of the rotating wheels 2 to cut when the rotating wheels 2 rotate. The cutting mechanism 5 arranged on the outer wall of the rotating wheel 2 and driven synchronously by the power mechanism 4, the cutting mechanism 5 includes a groove opened in the outer wall of the rotating wheel 2, and two movable plates 51 are symmetrically arranged on the inner wall of the groove. Two cutters 52 are symmetrically fixed on the opposite side of one end of the two movable plates 51. The top of the base plate 1 is provided with a pushing assembly for synchronously pushing the two cutters 52 to be close to each other for cutting the abrasive wire. The pushing assembly includes two vertical columns 53 symmetrically arranged on both sides of the rotating wheel 2, and two circular blocks 54 are symmetrically fixed on the top ends of the two vertical columns 53. The side away from the two cutters 52 of each movable plate 51 is arranged as an inclined surface. The inner wall of the groove is provided with a reset assembly and a limiting assembly matched with the two movable plates 51. The reset assembly includes two rotating shafts 55 fixed on the bottom of one end of each movable plate 51 away from the two cutters 52, and the bottom ends of the two rotating shafts 55 are rotatably arranged on the inner wall of the groove. Torsional springs 56 are sleeved on the outer walls of the two rotating shafts 55, and the two ends of the torsional springs 56 are fixed with the movable plates 51 and the groove respectively. The limiting assembly includes two slide rods 57 fixed on the bottom of one end of each movable plate 51 adjacent to the two cutters 52, and two arc-shaped grooves 58 are symmetrically opened on the inner wall of the groove for sliding of the two slide rods 57. The abrasive wire cutting task does not require very high precision and cutting force, but only needs to ensure uniform distribution of force during cutting to avoid breakage of the abrasive wire due to uneven force or incomplete cutting. When the rotating wheel 2 rotates to a certain position, the two movable plates 51 are in contact with the two circular blocks 54 respectively. These circular blocks 54 play a physical blocking role. When the movable plate 51 is in contact with the circular block 54, the circular block 54 provides a power source or rotating point for the movable plate 51, so that the movable plate 51 is activated. The circular block 54 plays a limiting and guiding role, which blocks the movement of the movable plate 51 to ensure that the movable plate 51 can only slide within a certain range. When the movable plate 51 passes through, they become a driving force to promote the movable plate 51 to move in the correct direction. Each movable plate 51 is correspondingly movable through cooperation with the rotating shaft 55.In the process of the movement of the movable plate 51, the slide rod 57 slides along the arc-shaped slot 58, thereby limiting the movement range of the movable plate 51, effectively preventing the over-movement of the movable plate 51, and ensuring that the cutter 52 can accurately approach the abrasive wire for cutting. When the two movable plates 51 move to the appropriate positions, they will cause the two cutters 52 to relatively approach and cut the abrasive wire. When the two movable plates 51 pass through the round block 54 and complete the cutting action, the two torsional springs 56 play a role in helping the movable plate 51 to reset. The resetting mechanism is to ensure that the equipment returns to the original state after each operation, so as to prepare for the next cutting.

[0023] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
