Description

Technical Field

[0001] This utility model relates to the field of nail making machine technology, specifically a nail making machine with a feeding structure. Background Technology

[0002] A nail-making machine is an industrial device that uses automated machining to transform metal wire (such as scrap steel bars and iron wire) into standard nails. Its core principle is turning waste into treasure, utilizing processes such as wire drawing, stamping, cutting, and polishing to achieve efficient and low-cost nail production. With waste recycling and automated production at its core, the nail-making machine transforms low-value metals into high-demand standard parts, combining economic efficiency, environmental friendliness, and technological adaptability, making it a practical piece of equipment for small-scale manufacturing.

[0003] Based on existing nail-making machines, it has been found that when using hydraulic nail cutting, the wire is prone to uneven stress, resulting in bending or cut deviation. In addition, the wire vibrates during feeding due to mechanical vibration or insufficient clamping, causing the cutting position to shift and forming an inclined cross-section. Therefore, this invention designs a nail-making machine with a feeding structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a nail-making machine with a feeding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A nail-making machine with a feeding structure includes a worktable, on which a limiting nail-making mechanism and a wire-pulling mechanism located on its left and right sides are provided. The limiting nail-making mechanism includes a support frame, a fixing plate, a nail-cutting structure, and a limiting structure. The nail-cutting structure includes a first cutter fixed at the upper end of a first hydraulic cylinder and its piston rod end to the support frame, and a second cutter fixed at the lower end of a second hydraulic cylinder and its piston rod end to the support frame, with a wire cutting position formed between the first cutter and the second cutter. The limiting structure includes a drive motor, a drive gear, and a transmission gear on the fixing plate. The upper end of the transmission gear is connected to a first transmission screw, and the lower end is connected to a second transmission screw with symmetrical thread direction. The first transmission screw is equipped with a first displacement block and a parallel first limiting rod, and the second transmission screw is equipped with a second displacement block and a parallel second limiting rod. Two sets of first support rods and a first clamping plate are fixedly connected to the front end of the first displacement block, and two sets of second support rods and a second clamping plate are fixedly connected to the front end of the second displacement block. The wire-pulling mechanism includes a support plate, a drum, a servo motor driving the drum, and a first wire pressing plate on the left side and a second wire pressing plate on the right side of the support frame.

[0007] Optionally, in the nail-cutting structure, the first hydraulic cylinder and the first cutter, and the second hydraulic cylinder and the second cutter are symmetrically distributed vertically and vertically with the wire as the plane of symmetry.

[0008] Optionally, in the limiting structure, the first displacement block is simultaneously threadedly connected to the first transmission screw and slidably sleeved on the first limiting rod, and the second displacement block is simultaneously threadedly connected to the second transmission screw and slidably sleeved on the second limiting rod.

[0009] Optionally, the first clamping plate is vertically fixed to the front end of the first displacement block by the first support rod, and is used to press the upper surface of the wire; the second clamping plate is vertically fixed to the front end of the second displacement block by the second support rod, and is used to press the lower surface of the wire.

[0010] Optionally, in the wire pulling mechanism, the first and second wire pressing discs are arranged in pairs, and multiple sets of wire pressing discs cooperate to confine the wire to the middle of the conveying path.

[0011] Optionally, the first transmission screw and the second transmission screw have opposite thread directions, and the drive motor drives the two screws to rotate in opposite directions synchronously through the drive gear and the transmission gear.

[0012] Optionally, when the transmission gear rotates, the first displacement block and the second displacement block move in opposite directions, so that the first clamping plate and the second clamping plate move synchronously towards each other to clamp the wire.

[0013] Optionally, the first pressure plate is located on the left side of the support frame, the second pressure plate is located on the right side of the support frame, and the reel is mounted on the support plate and driven by a servo motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a limiting nail-cutting mechanism is provided. Through the mechanical linkage between the bidirectional screw and the limiting rod, the clamping plate moves synchronously, eliminating the lateral deviation of the wire when cutting nails in traditional hydraulic systems. The symmetrically distributed hydraulic cylinders and cutters ensure that the shearing force is evenly distributed, avoiding the tilting of the cut.

[0016] 2. In this utility model, a wire pulling mechanism is provided, and a servo motor works with a drum to achieve precise feeding. Multiple sets of pressure plates form a three-level constraint, which effectively suppresses lateral vibration during the wire conveying process and ensures the accuracy of the cutting position.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Please see Figures 1-9In this embodiment of the present invention, a nail-making machine with a feeding structure includes a workbench 1, on which a limiting nail-making mechanism 2 and a wire-pulling mechanism 3 located on its left and right sides are provided; the limiting nail-making mechanism 2 includes a support frame 201, a fixing plate 206, a nail-cutting structure, and a limiting structure; the nail-cutting structure includes a first hydraulic cylinder 202 with its upper end fixed to the support frame 201 and a first cutter 203 at the end of its piston rod, and a second hydraulic cylinder 204 with its lower end fixed to the support frame 201 and a second cutter 205 at the end of its piston rod, with a wire 4 cutting position formed between the first cutter 203 and the second cutter 205; the limiting structure includes a drive motor 207, a drive gear 208, and a transmission gear 20 on the fixing plate 206. 9. The upper end of the transmission gear 209 is connected to the first transmission screw 210, and the lower end is connected to the second transmission screw 215 with symmetrical thread direction. The first transmission screw 210 is equipped with a first displacement block 212 and a parallel first limiting rod 211. The second transmission screw 215 is equipped with a second displacement block 217 and a parallel second limiting rod 216. The front end of the first displacement block 212 is fixedly connected to two sets of first support rods 213 and a first clamping plate 214. The front end of the second displacement block 217 is fixedly connected to two sets of second support rods 218 and a second clamping plate 219. The wire pulling mechanism 3 includes a support plate 301, a drum 302, a servo motor 303 that drives the drum 302, and a first pressing plate 304 on the left side and a second pressing plate 305 on the right side of the support frame 201.

[0031] When the drive motor 207 starts, it drives the two screws to rotate synchronously in opposite directions via the gear set. The first displacement block 212 moves to the right along the first transmission screw 210, while the second displacement block 217 moves to the left along the second transmission screw 215, so that the first clamping plate 214 and the second clamping plate 219 form symmetrical clamping forces on the upper and lower surfaces of the wire 4. After clamping is completed, the first hydraulic cylinder 202 and the second hydraulic cylinder 204 advance synchronously, and the first cutter 203 and the second cutter 205 move towards each other to complete the shearing. During the shearing process, the displacement of the wire 4 is greatly reduced.

[0032] The wire 4 on the drum 302 is guided by two sets of pressure plates. The servo motor 303 is pulse controlled and drives the drum 302 to rotate every time it is cut, thereby feeding the material.

[0033] At the start of the cutting cycle, servo motor 303 first completes the feeding; then drive motor 207 runs to clamp the clamping plate; finally, the dual hydraulic cylinders complete the shearing. Throughout the process, the straightness deviation of wire 4 is significantly reduced, and the flatness of the cut is optimized.

[0034] The working principle of this utility model is as follows: The nail-making machine with a feeding structure achieves high-precision nail making through the coordinated operation of the limiting nail-making mechanism 2 and the wire-pulling mechanism 3. The servo motor 303 drives the drum 302 to release the iron wire 4, which enters the cutting position after being guided by the second pressure plate 305; the drive motor 207 drives the first transmission screw 210 and the second transmission screw 215 to rotate in opposite directions through the drive gear 208 and the transmission gear 209, so that the first displacement block 212 and the second displacement block 217 slide towards each other along the first limiting rod 211 and the second limiting rod 216, thereby driving the first clamping plate 214 and the second clamping plate 219 to clamp the iron wire 4 up and down; then the first hydraulic cylinder 202 drives the first cutter 203 and the second cutter 205 driven by the second hydraulic cylinder 204 to cut symmetrically, completing the cutting of the iron wire 4 in the nail making process.

[0035] 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.
