Description

Technical Field

[0001] This application relates to the field of double wire clamp manufacturing technology, and in particular to a double wire clamp forming equipment. Background Technology

[0002] Double-wire clamps, formed by two layers of steel wire wrapped around each other, are widely used for connecting, fastening, and sealing interfaces of nylon plastic hoses, fabric-reinforced hoses, water pipes, gas pipes, etc. Currently, the forming of these double-wire clamps relies on a spring machine body and a pushing mechanism located directly in front of the spring machine body. The spring machine body includes a base plate and forming cutters mounted on the base plate. The base plate is mounted on a wall panel, and the pushing mechanism is installed directly in front of the base plate and can slide back and forth relative to the base plate. This pushing mechanism includes components such as a bracket, sliding components, and ejector pins, resulting in a large size and significant space consumption. The working process is as follows: first, the forming cutter bends both ends of a steel wire into rings; then, the pushing mechanism slides from front to back, applying pressure to the midpoint of the steel wire, folding the wire in half to obtain the double-layer clamp.

[0003] As can be seen from the above method, this method requires the push mechanism located in front of the spring machine body to work together with the spring machine body to complete the task. The push mechanism is not only complex in structure, but also large in size and occupies a lot of space.

[0004] Chinese patent CN220178042U discloses a double-wire clamp forming device, relating to the field of double-wire clamp manufacturing technology. The device includes a base plate, a forming mechanism, a feeding mechanism, and a coiling mechanism. The forming mechanism is mounted on the base plate. The feeding mechanism is located on one side of the base plate and is used to feed straight steel wires to the forming mechanism. The coiling mechanism is located between the feeding mechanism and the forming mechanism and is used to fold the steel wire in half before feeding it to the forming mechanism. The forming mechanism is used to bend the folded steel wire to form a ring clamp. This technical solution eliminates the push mechanism of the original forming equipment while still completing the forming of double-wire clamps, reducing the space occupied by the equipment.

[0005] In existing patents, the double wire clamps are folded in half by a coiling mechanism and then stamped around the central axis by multiple sets of tool assemblies in a forming mechanism. Finally, the formed double wire clamps are punched off by an ejector pin. The forming mechanism and operation steps are numerous and the process is complex, resulting in low processing efficiency for the double wire clamps. Utility Model Content

[0006] In order to overcome the problems existing in the prior art, this application provides a double steel wire clamp forming device.

[0007] The double steel wire clamp forming equipment provided in this application adopts the following technical solution:

[0008] A double-wire clamp forming device includes a feeding mechanism, a coiling mechanism, and a forming mechanism. The feeding mechanism is located at one end of the device and is used to feed straight steel wires to the forming mechanism. The coiling mechanism is located between the feeding mechanism and the forming mechanism and is used to fold the steel wires in half before feeding them to the forming mechanism. The forming mechanism is used to bend the folded steel wires into annular clamps, including a base plate and a forming shaft and a movable mandrel installed at the center of the base plate. Several sets of stamping components are distributed circumferentially around the forming shaft.

[0009] By adopting the above technical solution, the feeding mechanism conveys a straight steel wire from one end of the equipment to the forming mechanism. Before reaching the forming mechanism, the steel wire passes through a coiling mechanism located between the feeding mechanism and the forming mechanism and is folded in half. Then, the folded steel wire enters the forming mechanism and is gradually stamped by several sets of stamping components distributed around the forming shaft installed in the center of the substrate. Finally, the folded steel wire is bent into a ring clamp. During this process, the movable mandrel installed in the center of the substrate serves as an auxiliary forming and double steel wire clamp unloading mechanism.

[0010] Preferably, the feeding mechanism adopts gear feeding, lead screw feeding, or swing arm feeding.

[0011] By adopting the above technical solutions, the feeding mechanism respectively adopts the gear feeding structure in the automatic stamping and bending forming machine with gear feeding in CN221754382U, the screw feeding structure in the automatic stamping and bending forming machine with screw feeding in CN221773199U, and the swing arm feeding mechanism in the automatic stamping and bending forming machine in CN117983746A.

[0012] Preferably, the winding mechanism includes a winding section and a limiting section, wherein the winding section includes a winding platform and a central shaft and a winding shaft on the bottom surface of the winding platform, and the central shaft is coaxial with the winding platform. The top of the winding platform is driven by a motor. A wire groove adapted to the wire is provided at the same height of the central shaft and the winding shaft, and the gap between the central shaft and the winding shaft is adapted to the wire.

[0013] Preferably, the limiting part includes a limiting block and a limiting groove that connects the coiling part and the feeding end of the forming mechanism, wherein the width of the limiting groove is adapted to the diameter of the steel wire.

[0014] By adopting the above technical solution, in the process of forming a double steel wire clamp, the straight steel wire first enters the coiling mechanism. In the coiling section, the motor drives the coiling platform to rotate, and the steel wire is placed in a limiting groove that is at the same height as the central shaft and the coiling shaft and is adapted to itself. The gap between the central shaft and the coiling shaft is adapted to assist in the positioning of the steel wire. As the coiling platform rotates, the steel wire is gradually folded around the central shaft and the coiling shaft. The folded steel wire then enters the limiting section and is precisely guided and conveyed along the limiting groove that connects the coiling section and the feeding end of the forming mechanism and is adapted in width. Finally, it smoothly enters the forming mechanism for the subsequent bending into a ring clamp process.

[0015] Preferably, the stamping assembly includes a main stamping block above the forming shaft and an auxiliary stamping block below the forming shaft. The main stamping block has a first stamping groove and a second stamping groove sequentially formed below it. A cutting blade is provided on the main stamping block near the forming limiting block. The first stamping groove is in contact with the outer surface of the upper part of the combination of the forming shaft and the movable mandrel. The second stamping groove is in contact with the outer surface of the upper part of the forming shaft.

[0016] Preferably, a positioning block for limiting the steel wire is also installed above the forming shaft of the substrate. The positioning block is driven to move up and down and slide on the substrate by the positioning stamping block, and the positioning block is adapted to the positioning groove on the top surface of the second stamping groove.

[0017] Preferably, a guide wire is installed at the outer end of the forming shaft, the back of the movable mandrel is driven by a power mechanism, the main stamping block, the auxiliary stamping block and the positioning stamping block are all driven by a drive mechanism, and the power mechanism, the drive mechanism, the feeding mechanism and the coiling mechanism are controlled by a PLC controller.

[0018] By adopting the above technical solution, the folded steel wire, fed by the feeding mechanism and the coiling mechanism, is conveyed to a set position above the forming shaft and the movable mandrel. At this time, the PLC controller controls the positioning punch block to drive the positioning block to descend. Then, the drive mechanism drives the main punch block to descend, and the cutting blade near the forming limit block cuts the steel wire. The first punching groove of the main punch block first fits against the upper outer side of the combination of the forming shaft and the movable mandrel to perform preliminary punching and forming of the steel wire. Meanwhile, the auxiliary punch block cooperates in punching from below the forming shaft under the action of the drive mechanism. Subsequently, the movable mandrel retracts into the base plate under the action of the power mechanism, which is driven by a hydraulic cylinder. The second punching groove fits against the upper outer side of the forming shaft for further punching. At this time, the positioning block and the second punching groove of the main punch block... The positioning groove on the top surface of the pressure groove is adapted to precisely limit the steel wire. Throughout the process, the feeding mechanism, the coiling mechanism, and all power and drive mechanisms are controlled by a PLC controller to ensure efficient and precise forming of the double steel wire clamp. The drive mechanism includes a base and a drive plate that slides on the base. An adjustment block is fixedly installed at one end of the bottom of the drive plate, and a movable block with adjustable position is installed at the other end of the drive plate. The position of the movable block is adjusted along the movable groove by the adjusting screw at the end of the drive plate. The end of the drive plate away from the adjusting screw is used to install the main stamping block, auxiliary stamping block, or positioning stamping block. The conjugate cam installed on the base is driven by the drive motor in the drive mechanism, and the conjugate cam is adapted to the adjusting block and the movable block. The rotation of the conjugate cam can drive the drive plate to slide on the base.

[0019] Preferably, the forming shaft and the movable mandrel are cylindrical in shape, wherein the cross-section of the forming shaft is circular, and the movable mandrel adopts two sets of mirror-distributed components, including a semi-circular upper part and a rectangular lower part, wherein an arc-shaped groove is used at the transition between the circular and rectangular parts.

[0020] Preferably, the auxiliary stamping blocks are symmetrically installed on both sides below the movable mandrel, and the stamping end of the auxiliary stamping block is adapted to the arc-shaped groove on the outer side of the lower part of the movable mandrel.

[0021] By adopting the above technical solution, after the folded steel wire is fed to the forming mechanism, it is positioned centered on a cylindrical forming shaft with a circular cross-section. Two sets of mirror-distributed movable mandrels assist in forming from both sides. The upper half of the mandrels is attached to the upper part of the steel wire, guiding the steel wire to initially bend into an arc shape. The rectangular structure of the lower half provides stable support, while the arc groove at the transition between the circle and the rectangle ensures a natural transition in the bending of the steel wire. During this process, auxiliary stamping blocks symmetrically installed on both sides below the movable mandrels, under the action of the drive mechanism, have their stamping ends closely fitted with the arc groove on the outer side of the lower part of the movable mandrel, simultaneously stamping the steel wire from below. Working together with the movable mandrels, they apply force, causing the steel wire to be gradually bent into a ring clamp along the circular contour of the forming shaft, completing the forming of the double steel wire clamp.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application sets up a collaborative structure of feeding mechanism, coiling mechanism and forming mechanism. The coiling mechanism realizes the folding of steel wire and direct delivery to the forming mechanism. The traditional complex and space-consuming top pushing mechanism is eliminated. The design of movable mandrel not only can cooperate with the forming of double steel wire clamp, but the advance and retreat of movable mandrel can also realize the unloading of the formed double steel wire clamp.

[0024] 2. The forming mechanism in this application adopts a forming shaft at the center of the substrate, a movable mandrel, and a circumferentially distributed stamping assembly. The stamping assembly includes a main stamping block and an auxiliary stamping block. The main stamping block is provided with first and second stamping grooves adapted to the forming shaft and integrates a cutting blade. The main stamping block is used to pre-form two semicircles on the movable mandrel. After the movable mandrel retracts, the forming is performed on the forming block. The two strokes of the main stamping block and the movable mandrel reduce the total number of forming blades, thereby reducing the processing cost. Moreover, the total stroke of the forming blades is shorter than that of the prior art, which effectively improves the processing efficiency.

[0025] 3. The feeding mechanism in this application supports multiple feeding methods such as gears, lead screws, or rocker arms. The coiling part and the limiting part of the coiling mechanism achieve precise folding and guidance of the steel wire through the central shaft, the coiling shaft, and the matching limiting groove. The upper semicircle, lower rectangle, and arc transition of the mirror column structure of the movable mandrel cooperate with the auxiliary stamping block. Furthermore, the drive mechanism adopts a conjugate cam drive design, which is more stable than the spring pull-back design in the prior art, ensuring the forming accuracy of the clamp. The entire set of equipment has a compact structure and a high degree of automation, which improves production efficiency while ensuring the stability of product quality. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a double steel wire clamp forming device.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A double-wire clamp forming device includes a feeding mechanism, a coiling mechanism, and a forming mechanism. The feeding mechanism is located at one end of the device and is used to feed straight steel wires to the forming mechanism. The coiling mechanism is located between the feeding mechanism and the forming mechanism and is used to fold the steel wires in half before feeding them to the forming mechanism. The forming mechanism is used to bend the folded steel wires to form an annular clamp. The device includes a base plate 1 and a forming shaft 11 and a movable mandrel 12 installed at the center of the base plate 1. Several sets of stamping components 2 are distributed circumferentially around the forming shaft 11. The feeding mechanism conveys a straight steel wire from one end of the equipment to the forming mechanism. Before reaching the forming mechanism, the steel wire passes through a coiling mechanism located between the feeding mechanism and the forming mechanism and is folded. Then, the folded steel wire enters the forming mechanism and is gradually stamped by several sets of stamping components 2 distributed around the forming shaft 11 installed in the center of the substrate 1. Finally, the folded steel wire is bent into a ring clamp. During this process, the movable mandrel 12 installed in the center of the substrate 1 serves as an auxiliary forming and double steel wire clamp unloading mechanism.

[0034] Reference Figure 1 The feeding mechanism adopts gear feeding, lead screw feeding, or swing arm feeding. The specific structure is omitted in the figure. For specific structure reference, refer to the gear feeding structure in the automatic stamping and bending forming machine with gear feeding in CN221754382U, the lead screw feeding structure in the automatic stamping and bending forming machine with lead screw feeding in CN221773199U, and the swing arm feeding mechanism in the automatic stamping and bending forming machine in CN117983746A.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The coiling mechanism includes a coiling section 3 and a limiting section 4. The coiling section 3 includes a coiling platform 31, a central shaft 311 and a coiling shaft 312 on the bottom surface of the coiling platform 31, and the central shaft 311 is coaxial with the coiling platform 31. The top of the coiling platform 31 is driven by a motor 32. A wire groove 313 adapted to the steel wire is provided at the same height of the central shaft 311 and the coiling shaft 312, and the gap between the central shaft 311 and the coiling shaft 312 is adapted to the steel wire. The limiting section 4 includes a limiting block 41 and a limiting groove 42 connecting the coiling section 3 and the feeding end of the forming mechanism, wherein the width of the limiting groove 42 is adapted to the diameter of the steel wire. During the forming process of the double wire clamp, the straight wire first enters the coiling mechanism. In the coiling section 3, the motor 32 drives the coiling platform 31 to rotate. The wire is placed in the limiting groove 42, which is at the same height as the central shaft 311 and the coiling shaft 312 and is adapted to itself. The gap between the central shaft 311 and the coiling shaft 312 is adapted to assist in the positioning of the wire. As the coiling platform 31 rotates, the wire is gradually folded around the central shaft 311 and the coiling shaft 312. The folded wire then enters the limiting section 4 and is precisely guided and conveyed along the limiting groove 42, which connects the coiling section 3 and the feeding end of the forming mechanism and is adapted in width. Finally, it smoothly enters the forming mechanism for the subsequent bending into a ring clamp.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The stamping assembly 2 includes a main stamping block 21 above the forming shaft 11 and an auxiliary stamping block 22 below the forming shaft 11. The main stamping block 21 has a first stamping groove 211 and a second stamping groove 212 sequentially formed below it. A cutting blade 213 is provided on the main stamping block 21 near the forming limiting block 41. The first stamping groove 211 is in contact with the outer surface of the upper part of the combination of the forming shaft 11 and the movable mandrel 12, and the second stamping groove 212 is in contact with the outer surface of the upper part of the forming shaft 11. A positioning block 13 for limiting the steel wire is also installed above the forming shaft 11 of the substrate 1. The positioning block 13 is driven to slide and move on the substrate 1 by the positioning stamping block 23, and the positioning block 13 is adapted to the positioning groove 214 on the top surface of the second stamping groove 212. The outer end of the forming shaft 11 is also equipped with a guide wire 111. The back of the movable mandrel 12 is driven by a power mechanism. The main stamping block 21, the auxiliary stamping block 22 and the positioning stamping block 23 are all driven by the drive mechanism 5. The power mechanism, the drive mechanism 5, the feeding mechanism and the coiling mechanism are controlled by a PLC controller. After the folded steel wire, fed by the feeding mechanism and the coiling mechanism, is conveyed to the set position above the forming shaft 11 and the movable mandrel 12, the PLC controller controls the positioning punch block 23 to drive the positioning block 13 to descend. Then, the drive mechanism 5 drives the main punch block 21 to descend, and the cutting blade 213 near the forming limit block 41 cuts the steel wire. The first punch groove 211 of the main punch block 21 first fits against the upper outer side of the combination of the forming shaft 11 and the movable mandrel 12 to perform preliminary punching and forming of the steel wire. Meanwhile, the auxiliary punch block 22 cooperates to punch from below the forming shaft 11 under the action of the drive mechanism 5. Subsequently, the movable mandrel 12 retracts into the base plate 1 under the action of the power mechanism, which is driven by a hydraulic cylinder. The second punch groove 212 fits against the upper outer side of the forming shaft 11 for further punching. At this time, the positioning block 13 matches the positioning groove 214 on the top surface of the second punch groove 212 of the main punch block 21 to perform further punching of the steel wire. The wire is precisely positioned. Throughout the process, the feeding mechanism, the coiling mechanism, and all power and drive mechanisms 5 are controlled by a PLC controller to ensure efficient and precise forming of the double steel wire clamp. The drive mechanism 5 includes a base 51 and a drive plate 52 slidably mounted on the base 51. An adjusting block 521 is fixedly mounted on one end of the bottom of the drive plate 52, and a movable block 522 with adjustable position is mounted on the other end of the drive plate 52. The position of the movable block 522 is adjusted along the movable groove 524 by the adjusting screw 523 at the end of the drive plate 52. The end of the drive plate 52 away from the adjusting screw 523 is used to install the main stamping block 21, the auxiliary stamping block 22, or the positioning stamping block 23. The conjugate cam 511 mounted on the base 51 is driven by the drive motor 32 in the drive mechanism 5, and the conjugate cam 511 is adapted to the adjusting block 521 and the movable block 522. The rotation of the conjugate cam 511 can drive the drive plate 52 to slide on the base 51.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The forming shaft 11 and the movable mandrel 12 are cylindrical in shape. The forming shaft 11 has a circular cross-section, and the movable mandrel 12 consists of two sets of mirror-image mandrels, including a semi-circular upper part and a rectangular lower part. The transition between the circular and rectangular parts is achieved using an arc-shaped groove. Auxiliary stamping blocks 22 are symmetrically installed on both sides below the movable mandrel 12, and the stamping ends of the auxiliary stamping blocks 22 are adapted to the arc-shaped grooves on the outer side of the lower part of the movable mandrel 12. After the folded steel wire is fed to the forming mechanism, it is positioned centered on the cylindrical forming shaft 11 with a circular cross-section. The two sets of mirror-image movable mandrels 12 assist in forming from both sides. The upper semi-circular part of the mandrels fits against the upper part of the steel wire, guiding the wire to initially bend into an arc shape. The rectangular structure of the lower part provides stable support, while the arc-shaped grooves at the transition between the circular and rectangular parts ensure a natural transition in the bending of the steel wire. During this process, the auxiliary stamping blocks 22, which are symmetrically installed on both sides below the movable mandrel 12, are driven by the drive mechanism 5. Their stamping ends are closely matched with the arc-shaped groove on the outer side of the lower part of the movable mandrel 12. They simultaneously stamp the steel wire from below and work together with the movable mandrel 12 to apply force, so that the steel wire is gradually bent into a ring clamp along the circular outline of the forming shaft 11, thus completing the forming of the double steel wire clamp.

[0038] Working principle: When the double wire clamp forming equipment is working, the feeding mechanism guides the wire into the coiling mechanism, and then transmits it to the forming mechanism through the limiting groove 42 on the central shaft 311 and the coiling shaft 312. When the end of the wire reaches the position of the cutting blade 213, the feeding mechanism stops feeding. The motor 32 in the coiling mechanism drives the coiling platform 31 to rotate, thereby driving the coiling shaft 312 to rotate around the axis of the central shaft 311, bending the wire. After bending, the distance between the free ends of the wire is less than the distance between the wires on both sides of the bent part. After bending is completed, the motor 32 drives the coiling shaft 312 to reset, the feeding mechanism starts, and the folded steel wire moves towards the forming mechanism through the limiting groove 42 in the limiting block 41. When the free end of the folded steel wire reaches the position of the cutting blade 213, the feeding mechanism stops feeding. The positioning punching block drives the positioning block 13 to move downward under the action of the driving mechanism 5, and presses the folded steel wire stably on the forming shaft 11. Then, under the action of the driving mechanism 5, the main punching block 21 is pressed down. The first punching groove 211 on the main punching block 21 presses the folded steel wire stably on the outside of the forming shaft 11 and the movable mandrel 12. At the same time, the cutting blade 213 on the main punching block 21 cuts the free end of the folded steel wire. Then, the two ends of the folded steel wire are bent at the arc groove outside the movable mandrel 12 by the auxiliary punching block 22. At this time, the coiling mechanism and the feeding mechanism fold the next section of steel wire again according to the above process. Next, the power mechanism drives the movable mandrel 12 to retract into the substrate 1, and the drive mechanism 5 drives the main stamping block 21 to continue pressing down, so that the second stamping groove 212 on the main stamping block 21 stably presses the folded steel wire onto the outside of the forming shaft 11, and the two ends of the folded steel wire cross to form a double steel wire clamp. After completion, the forming mechanism is reset under the action of the drive mechanism 5, and the movable mandrel 12 is pushed out from the substrate 1 under the action of the power mechanism. At the same time, the product fitted on the forming shaft 11 is pushed out and enters the collection box along the guide wire 111 for collection. This operation is repeated to achieve efficient production of double steel wire clamps.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
