Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically a novel feeding mechanism for a cold forging machine. Background Technology

[0002] A sewing machine needle is a type of needle used in sewing machines, commonly found in various sewing and embroidery equipment. There are hundreds of types of sewing machine needles produced domestically alone. During the sewing process, to achieve the ideal match between the needle, fabric, and thread, it is essential to select the appropriate needle. The type of needle is determined by the model and specifications of the sewing machine and the properties of the fabric being sewn. The machine's operating characteristics dictate the needle selection; different types of machines require different models and specifications of needles. Currently, during needle production, the steel wire needs to be cut first, and then the cut material is manually placed on a cold forging table, which is inefficient.

[0003] The automatic feeder disclosed in CN216612677U uses pusher rollers to push the material accumulated on the upper part of the longitudinal and transverse partitions into the placement trough. When the material in the placement trough is full, it is pushed into the subsequent placement trough as the feed belt moves. The material in each placement trough is evenly distributed. However, it cannot directly connect with the cold forging die of the cold forging machine. The material needs to be placed on the cold forging table manually, which results in low efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cold forging machine feeding mechanism that eliminates the need for manual placement of cut materials one by one onto the cold forging table, thereby improving work efficiency.

[0005] To solve the above technical problems, this utility model provides a novel cold forging machine feeding mechanism, including a platform with a receiving groove and an arc-shaped conveying groove. A feeding hopper is set above the receiving groove, and a cutting blade is set above the feeding hopper. An arc-shaped conveying groove is set in front of the receiving groove. A pushing shaft passes through one side wall of the receiving groove. A pushing plate is installed at one end of the pushing shaft, and a feeding cylinder is installed at the other end of the pushing shaft. The feeding cylinder is fixed to the outer wall of the receiving groove, and the pushing plate is located inside the receiving groove. The pushing plate faces the arc-shaped conveying groove. A cold forging die head is set at one end of the arc-shaped conveying groove, and the other end of the arc-shaped conveying groove is connected to the cold forging die cavity. Cutters are symmetrically mounted on a mounting plate. Through holes are opened on the mounting plate, and wire cavities are installed in the through holes. The cutters are symmetrically distributed on both sides of the through holes.

[0006] By adopting the above technical solution, after the steel wire is cut, it is fed from the feeding hopper into the receiving groove, and then pushed from the receiving groove into the arc-shaped conveying groove by the pusher plate. The cold forging die head sends the material to the cold forging die cavity for extrusion and molding. There is no need for manual placement of the cut materials on the cold forging table, which improves work efficiency.

[0007] Preferably, the feed hopper has a V-shaped cross-section, and the bottom opening size is adapted to the material size.

[0008] By adopting the above technical solution, the material from the needle falls into the feed trough in a specified direction. This directional feeding method can greatly improve the accuracy and efficiency of feeding and reduce the chaos and waste of materials during the feeding process.

[0009] Preferably, on the mounting plate, cutter grooves are symmetrically installed on both sides of the through hole, and the cutter passes through the cutter grooves.

[0010] By adopting the above technical solution, the symmetrically installed cutter grooves provide precise guidance and positioning for the cutter, thereby achieving precise cutting.

[0011] Preferably, a limiting part is provided at the tail of the blade of the cutter.

[0012] By adopting the above technical solution, the steel wire is secured by the limiting part, ensuring stable shearing and preventing it from slipping out.

[0013] Preferably, the tail end of the cutter is mounted on the piston rod of the shearing cylinder, and the shearing cylinder is fixed to the mounting plate.

[0014] By adopting the above technical solution, the shearing cylinder drives the cutter, making the shearing of steel wire stable. The shearing cylinder and the cutter are assembled together on the mounting plate, making the structure compact, the overall size of the mechanism small, and the performance reliable.

[0015] Preferably, the cold forging die head is provided with a receiving part.

[0016] By adopting the above technical solution, the presence of the receiving part can reduce the direct impact and wear of the steel wire segment on the cold forging die head, thereby extending the service life of the die.

[0017] Preferably, a ramp-shaped conveying section is provided between the arc-shaped conveying trough and the receiving trough.

[0018] By adopting the above technical solution, the design of the ramp-shaped conveyor section provides a smooth transition surface, which facilitates the rolling of steel wire material into the arc-shaped conveyor trough. This reduces the impact on the steel wire material during rolling and lowers the risk of scratches or deformation on the material surface, which is crucial for maintaining the quality and integrity of the steel wire material.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, after the steel wire is cut, it is fed from the feeding hopper into the receiving groove, and then pushed from the receiving groove into the arc-shaped conveying groove by the pusher plate. The cold forging die head sends the material to the cold forging die cavity for extrusion and molding. There is no need for manual placement of the cut materials on the cold forging table, which improves work efficiency.

[0021] 2. The feed hopper of this utility model has a V-shaped cross section, and the bottom opening size is adapted to the material size, so that the material from the needle falls into the feed trough in a specified direction. This directional feeding method can greatly improve the accuracy and efficiency of feeding and reduce the confusion and waste of materials during the feeding process.

[0022] 3. The design of the inclined conveyor section of this utility model provides a smooth transition surface, which facilitates the rolling of steel wire material into the arc-shaped conveyor groove, reduces the impact on the steel wire material during rolling, and lowers the risk of scratches or deformation on the material surface.

Detailed Implementation

[0029] like Figure 1As shown, the novel cold forging machine feeding mechanism includes a platform 1, on which a receiving groove 2 and an arc-shaped conveying groove 3 are provided. A feeding hopper 16 is provided above the receiving groove 2, and a cutting blade 8 is provided above the feeding hopper 16. An arc-shaped conveying groove 3 is provided in front of the receiving groove 2. A push shaft 9 passes through one side wall of the receiving groove 2. A push plate 5 is installed at one end of the push shaft 9, and a feeding cylinder 4 is installed at the other end of the push shaft 9. The feeding cylinder 4 is fixed to the outer wall of the receiving groove 2, and the push plate 5 is located inside the receiving groove 2. A cold forging die head 6 is provided at one end of the arc-shaped conveying groove 3, and a cold forging die cavity is provided at the other end of the arc-shaped conveying groove 3. The cutting blades 8 are symmetrically installed on a mounting plate 10. The bottom of the mounting plate 10 is welded and fixed to the top surface of the receiving groove 2. The mounting plate 10 has a notch for accommodating a bracket 17. A through hole 19 is provided on the mounting plate 10, and a wire cavity 7 is installed in the through hole 19. The cutting blades 8 are symmetrically distributed on both sides of the through hole 19. After the steel wire is cut, it is fed from the feeding hopper 16 into the receiving groove 2. The pusher plate 5 then feeds the material from the receiving groove 2 into the arc-shaped conveying groove 3. The cold forging die head 6 sends the material to the cold forging die cavity for extrusion molding. This eliminates the need for manual placement of the cut materials onto the cold forging table, thus improving work efficiency.

[0030] In this embodiment, the bottom edge of the cavity of the cold forging die 6 is tangent to the bottom edge of the arc-shaped conveying groove 3, facilitating the entry of the steel wire segment into the cold forging die 6. The cold forging die cavity and the arc-shaped conveying groove 3 are connected, and the bottom edge of the circumference of the cold forging die cavity and the bottom edge of the arc-shaped conveying groove 3 are on the same straight line. The cold forging die 6 is provided with a receiving part 15. The presence of the receiving part 15 can reduce the direct impact and wear of the steel wire segment on the cold forging die, thereby extending the service life of the die.

[0031] like Figure 2 As shown, a ramp-shaped conveying section 18 is provided between the arc-shaped conveying trough 3 and the receiving trough 2. The design of the ramp-shaped conveying section 18 provides a smooth transition surface, which facilitates the rolling of the steel wire material into the arc-shaped conveying trough. This reduces the impact on the steel wire material during rolling and lowers the risk of scratches or deformation on the material surface, which is crucial for maintaining the quality and integrity of the steel wire material.

[0032] like Figure 3 As shown, the feed hopper 16 has a V-shaped cross-section, and the bottom opening size is adapted to the material size, allowing the material from the needle to fall into the feed trough in a specified direction. This directional feeding method can greatly improve the accuracy and efficiency of feeding and reduce material confusion and waste during the feeding process. The feed hopper 16 is installed above the receiving trough 2 via a bracket 17, which spans across the top surface of the receiving trough 2.

[0033] like Figure 4 As shown, the cutting blade 8 has a limiting part 14 at the end of its blade. The limiting part 14 holds the steel wire in place to ensure that the steel wire is stable and does not slip off during cutting.

[0034] like Figure 5As shown, on the mounting plate 10, cutter grooves 11 are symmetrically installed on both sides of the through hole 19, and the cutter 8 passes through the cutter grooves 11. The symmetrically installed cutter grooves provide precise guidance and positioning for the cutter, achieving precise cutting.

[0035] The tail of the cutter 8 is mounted on the piston rod 12 of the shearing cylinder 13, which is fixed to the mounting plate 10. The shearing cylinder drives the cutter, ensuring stable wire shearing. Assembling the shearing cylinder and cutter together on the mounting plate results in a compact structure, making the overall mechanism small in size and reliable in performance.

[0036] During operation, the steel wire passes through the wire cavity 7 and is cut into segments by the cutter 8. The wire segments are then fed into the feeding hopper 16. Due to gravity, the wire segments fall along the hopper wall from the narrow bottom outlet, falling in a predetermined direction into the receiving trough 2. The pusher plate 5 pushes the wire segments into the arc-shaped conveying trough 3. In the arc-shaped conveying trough 3, the cold forging die head 6 moves forward, and the wire segments enter the die cavity of the cold forging die head 6. The presence of the receiving part makes it easier for the wire segments to be gathered into the cold forging die head 6. The cold forging die head 6 and the cold forging die cavity cooperate to perform cold forging operations, forging the shape of the die needle.
