This frame is used to support the springs and provide support, allowing the mattress to maintain its shape and provide comfortable support. The wire frame is generally strong and durable, and effectively distributes body pressure, improving the mattress's comfort and support.

[0003] The applicant's earlier application CN222491889U discloses a bed core frame forming device, including a frame, a straightening and feeding device, a cutting device, a bending and forming device, and a bending frame device.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0052] Example 1

[0053] refer to Figures 1-18A bed core frame forming device includes a frame 1 and a straightening and feeding device 2, a cutting device 3, a bending and forming device 4, a bending and frame device 5, and a receiving device 6 connected to the frame 1. The cutting device 3 is connected to the straightening and feeding device 2. The bending and forming device 4 includes a sleeve connection mechanism 41, a clamping and conveying mechanism 42, and a bending mechanism 43. The straightening and feeding device 2 and the sleeve connection mechanism 41 are arranged sequentially along the length of the frame 1. The bending and frame device 5 is arranged opposite to the sleeve connection mechanism 41. The clamping and conveying mechanism 42 is located between the sleeve connection mechanism 41 and the bending and frame device 5. The sleeve connection mechanism 41 is provided with symmetrically arranged clamping units 411. The bending and frame device 43 is connected to one side of the frame 1. The operating area of ​​the bending and frame device 43 is the bending area a, and the area below the bending and frame device 5 is the bending area b. The bending area a and the bending area b are arranged opposite to each other.

[0054] The frame 1 also has a swingable stop assembly 7 on one side. The stop assembly 7 is symmetrically arranged on one side of the frame 1. The stop assembly 7 can swing between the bend area a and the bend frame area b. The stop assembly 7 is used to limit the interference between the wire located in the bend area a and the wire located in the bend frame area b.

[0055] Regarding the working method of this forming equipment, the steel wire is first straightened by the straightening and feeding device 2, and then passes through the cutting device 3 and the clamping and conveying mechanism 42 in sequence. When the end of the steel wire reaches the bending mechanism 43, the bending mechanism 43 can clamp one end of the steel wire and swing it in a circle. When the bending mechanism 43 swings to the preset position, the clamping and conveying mechanism 42 clamps the steel wire. After the cutting device 3 cuts the steel wire, the clamping and conveying mechanism 42 drives the other end of the steel wire to move forward, so that the bending mechanism 43 is in the initial position and the two ends of the steel wire are opposite each other. In this state, the two clamping units 411 clamp the two ends of the steel wire respectively and insert the two ends of the steel wire into the sleeve of the sleeve connecting mechanism 41. The two ends of the steel wire are connected to the sleeve through the sleeve connecting mechanism 41. At this time, the steel wire completes the bending. Finally, it is conveyed to the bending frame device 5 through the clamping unit 411 for bending. After the bending is completed, it is directly lowered to the collecting device 6 for collection.

[0056] This working method has been described in the applicant's earlier application CN222491889U, and those skilled in the art can understand that this equipment is based on the original equipment with the addition of the material blocking component 7.

[0057] With the addition of the baffle assembly 7, during the bending operation, that is, after the clamping unit 411 conveys the wire to the bending device 5, the entire equipment will not stop working and wait for the bending to finish. Instead, after the bending mechanism 43 and the clamping and conveying mechanism 42 are reset, a new round of bending will begin. At this time, the bending area a and the bending frame area b will be in working state at the same time. The baffle assembly 7 swings between the bending area a and the bending frame area b. The baffle assembly 7 is used to limit the interference between the wire in the bending area a and the wire in the bending frame area b.

[0058] More specifically, regarding the principle of the stop assembly 7, since the steel wire is approximately circular when the bending mechanism 43 bends, it may become elliptical due to gravity and the clamping position of the clamping unit 411. As long as the stop assembly 7 intersects with its projection in the horizontal direction, it can restrict the wire from swinging in the bending area b. Similarly, when the bending mechanism bends, it is only necessary to ensure that the stop assembly 7 intersects with its projection in the horizontal direction to restrict the wire from swinging in the bending area a.

[0059] refer to Figure 4 , Figure 4 The two dashed areas are the curved area a and the curved frame area b, respectively.

[0060] Furthermore, the material blocking assembly 7 includes a fixed frame 71, a drive cylinder 72, and a stop rod 73. The fixed frame 71 is bolted to one side of the frame 1. The cylinder body of the drive cylinder 72 is hinged to the fixed frame 71. The power output end of the drive cylinder 72 is hinged to one end of the stop rod 73. The rod body of the stop rod 73 is rotatably connected to the fixed frame 71. The drive cylinder 72 is used to drive the stop rod 73 to swing from a vertical state to an inclined state. At this time, the stop rod 73 is partially located between the bend area a and the bend frame area b, and is used to limit the interference between the steel wire located in the bend area a and the steel wire located in the bend frame area b.

[0061] More specifically, in actual use, the optimal initial state for the stop lever 73 is vertical. However, it is sufficient to ensure that the horizontal projections of the stop lever 73, the wire in bending area a, and the wire in bending frame area b do not intersect in the initial state. The specific workflow is as follows: after the clamping unit 411 delivers the bent wire coil to the bending frame device 5, the drive cylinder 72 drives its piston to retract and drives the stop lever 73 to swing between bending area a and bending frame area b until it swings between them. After the bending is completed, the drive cylinder 72 drives its piston to retract. The piston extends and drives the stop lever 73 back to its initial state. At this time, the clamping unit 411 again transports the bent wire ring to the bending frame device 5. Regarding the installation method of the drive cylinder 72, the drive cylinder 72 can be mounted on the fixed frame 71 via an external mounting bracket. Specifically, a semi-threaded bolt can be used, that is, the cylinder body of the drive cylinder 72 is mounted on the mounting bracket with a semi-threaded bolt and nut, and the mounting bracket is also mounted on the fixed frame 71 with a semi-threaded bolt and nut. In other words, the cylinder body of the drive cylinder 72 and the mounting bracket are in a hinged state, and the mounting bracket and the fixed frame 71 are in a fixed connection state. A square plate 74 can be welded onto the stop lever 73, referring to the present application. Figure 3 The square plate 74 has four holes 741, among which the holes 741 that connect the square plate 74 and the fixing bracket 71 and the holes 741 that connect the square plate 74 and the driving cylinder 72 are arranged diagonally.

[0062] In a preferred embodiment, a plate 15 may be added to the frame 1 to improve safety. Specifically, the plate 15 is used to partially shield the material blocking assembly 7.

[0063] In this embodiment, a frame 9 is also fixedly connected to the bottom of the receiving device 6. The length of the frame 9 extends along the length direction of the frame 1. The two ends of the frame 9 have symmetrically arranged inclined surfaces 91, which are used for the baffle 73 to be attached to the frame 9.

[0064] Specifically, the bottom of the frame 9 and the receiving device 6 can be welded or bolted. Implicitly, after the steel wire is bent, the frame 9 is completely inside the steel wire loop in the horizontal projection, ensuring that the frame 9 can pass through the steel wire loop. The inclined surfaces 91 at both ends of the frame 9 can provide a limiting function for the stop bar 73, that is, when the stop bar 73 contacts the inclined surface 91 on the frame 9, it is in the swing position.

[0065] In this embodiment, the straightening and feeding device 2 includes a straightening mechanism 22 and a feeding mechanism 21. A placement layer 14 is located in the middle of the frame 1. The feeding mechanism 21, the sleeve connection mechanism 41, the clamping and conveying mechanism 42, and the bending frame device 5 are all located at the top of the frame 1. The straightening mechanism 22 is installed on the placement layer 14. One end of the placement layer 14 along its length has a support block 16. Two guide wheels 161 are arranged vertically on the support block 16. The two guide wheels 161 are used for the steel wire to pass through. After passing through the guide wheels 161, the steel wire bends in an arc towards the feeding mechanism 21 at the top of the frame 1. The top of the frame 1 can also be equipped with a support block 16 and guide wheels 161 to ensure that the steel wire smoothly bends from the placement layer 14 towards the top of the frame 1. For specific steel wire feeding details, please refer to [reference needed]. Figure 3 .

[0066] Specifically, the straightening mechanism 22, the wire feeding mechanism 21, the cutting device 3, and the bending frame device 5 are already described in Chinese patent CN108188312A, and are respectively in this solution. Figure 1 The recorded directly affiliated institutions are 222. Figure 2 The described wire feeding mechanism 4 Figure 2 The recorded cutting mechanism 5 and Figure 10 Therefore, the straightening mechanism 22, the wire feeding mechanism 21, the cutting device 3, and the bending frame device 5 will not be described in detail in this embodiment. As for the bending frame device 5, it can be directly installed or welded to the sleeve connection mechanism 41 so that the two are arranged opposite each other.

[0067] Preferably, the clamping and conveying mechanism 42 includes a transverse drive unit 421 connected to the frame 1, a support plate 422 connected to the transverse drive unit 421, a lifting module 423 connected to the support plate 422, and a first pneumatic gripper 424 connected to the power output end of the lifting module 423. The support plate 422 is provided with a first slide rail 4221 and a first slider 4222 connected to the first slide rail 4221. One side of the first pneumatic gripper 424 is connected to the first slider 4222.

[0068] Specifically, when the bending mechanism 43 swings to the preset position, the first pneumatic gripper 424 clamps the steel wire. After the cutting device 3 cuts the steel wire, the transverse drive unit 421 drives the first pneumatic gripper 424 to move backward, cooperating with the bending mechanism 43 to swing back to the initial state, so that the two ends of the steel wire are opposite each other. Then the lifting module 423 drives the first pneumatic gripper 424 to descend and reset under the drive of the transverse drive unit 421, so as to avoid the first pneumatic gripper 424 from affecting the operation of other devices. At the same time, with the cooperation of the first slide rail 4221 and the first slider 4222, the stability of the operation of the first pneumatic gripper 424 can be guaranteed.

[0069] Regarding the coupling between the bending frame mechanism 43 and the clamping and conveying mechanism 42, please refer to the description of the bending device in the specification of Chinese Patent CN108188312A.

[0070] In this embodiment, the bending mechanism 43 includes a swing arm 431 and a second pneumatic gripper 432. A rotary drive mechanism 11 is provided inside the frame 1. One end of the swing arm 431 is connected to the rotary drive mechanism 11, and the second pneumatic gripper 432 is connected to the other end of the swing arm 431. The rotary drive mechanism 11 drives the swing arm 431 to swing so that the second pneumatic gripper 432 swings in a circular motion. The frame 1 is also provided with a pressing cylinder 12 for driving the second pneumatic gripper 432 to clamp or release.

[0071] When one end of the steel wire reaches the position of the second pneumatic gripper 432, the downward pressure cylinder 12 drives the second pneumatic gripper 432 to clamp one end of the steel wire. Subsequently, driven by the rotary drive mechanism 11, the swing arm 431 rotates, causing the second pneumatic gripper 432 to swing in a circular motion, bending the steel wire. This method allows for more precise control of the bending process, ensuring the quality and accuracy of the bending. The descent of the first pneumatic gripper 424 is mainly to avoid collision with the second pneumatic gripper 432. Specifically, the rotary drive mechanism 11 can be a motor, or a motor plus gear transmission. The motor is fixedly installed inside the frame 1, and the power output end of the motor is fixedly connected to the swing arm 431; or the power output end of the motor is fixedly connected to the driving gear, and the driven gear is rotatably connected to one side of the frame 1, with the swing arm 431 fixedly connected to the driven gear.

[0072] Both the first pneumatic gripper 424 and the second pneumatic gripper 432 can be pneumatic grippers well known to those skilled in the art. Regarding the relationship between the second pneumatic gripper 432 and the downward-pressing cylinder 12, it should be specifically noted that the pneumatic power of the second pneumatic gripper 432 comes from the downward-pressing cylinder 12. Specifically, a hinged clamping plate 4321 is fixed on the swing arm. A torsion spring or spring is present at the hinge point between the clamping plate 4321 and the swing arm, maintaining a closed state. Above the clamping plate 4321 is the downward-pressing cylinder 12, which is the positional relationship when the swing arm is in its initial state. The function of the downward-pressing cylinder 12 is to push its piston downwards, acting on the clamping plate 4321 to open it. When the end of the steel wire is delivered to the opening between the clamping plate 4321 and the swing arm, the downward-pressing cylinder 12 drives its piston upwards. Under the action of the torsion spring, the clamping plate 4321 returns to the closed state and clamps the end of the steel wire. Regarding the fixing method of the pressing cylinder 12, the cylinder body can be fixed on the sleeve connection mechanism 41, or fixed on the frame by other frames. As long as the swing arm is in the initial state, the pressing cylinder 12 is located above the clamping plate 4321.

[0073] The specific structure and connection method of the bending mechanism 43 and the clamping and conveying mechanism 42, as well as the selection of the rotary drive mechanism 11 and the lifting module 423, are described in detail in the applicant's prior application CN222569112U. In this application, the transverse drive unit 421 uses a rodless cylinder, and the lifting module 423 uses a lifting cylinder. In this embodiment, the bending mechanism 43 and the clamping and conveying mechanism 42 have the same structure as the wire bending device described in the prior application CN222569112U.

[0074] The following describes the sleeve connection mechanism 41 in this embodiment. However, the sleeve connection mechanism 41 has been described in detail in the applicant's earlier applications CN222569136U and CN222491889U. Those skilled in the art can refer to the description of that solution or directly apply it to this solution. The sleeve connection mechanism 41 in this embodiment has the same structure as a wire sleeve connection device in the earlier application CN222491889U. The sleeve conveying unit 412 of this application corresponds to the sleeve conveying mechanism 12 of this solution, and the clamping unit 414 corresponds to the clamping mechanism 2 of this solution.

[0075] In this embodiment, the sleeve connection mechanism 41 includes a sleeve conveying unit 412, a connecting plate 413, and a clamping unit 414. The sleeve conveying unit 412 is connected to the frame 1, and the frame 1 is also provided with a longitudinal drive mechanism 13. The connecting plate 413 is connected to the longitudinal drive mechanism 13, and the clamping unit 414 is connected to the connecting plate 413. The connecting plate 413 is provided with a longitudinal drive unit 4131, and the longitudinal drive unit 4131 is provided with symmetrically arranged push modules 41311. The clamping units 411 are respectively connected to the push modules 41311 and located on both sides of the clamping unit 414. The push modules 41311 are used to drive the clamping units 411 to move closer or further away from each other. The sleeve conveying unit 412 is used to convey the sleeve to the clamping unit 414.

[0076] Specifically, the longitudinal drive mechanism 13 drives the connecting plate 413 to move forward and backward longitudinally. Under the drive of the longitudinal drive unit 4131, the clamping unit 411 moves towards the steel wire and clamps both ends of the steel wire. The sleeve conveying unit 412 conveys the sleeve to the pressing unit 414. Then, the longitudinal drive unit 4131 drives the clamping unit 411 to move backward, aligning both ends of the steel wire with the sleeve on the pressing unit 414. Under the drive of the push module 41311, the clamping units 411 move closer to each other and insert both ends of the steel wire into the sleeve. The pressing unit 414 presses both ends of the steel wire into the sleeve. Then, the longitudinal drive unit 4131 drives the clamping unit 411 to convey the steel wire to the bending frame device 5. The sleeve conveying unit 412 can use a vibratory feeder, which is well known to those skilled in the art, for conveying. In this embodiment, the longitudinal drive mechanism 13 can be a cylinder plus guide rod well known to those skilled in the art, or a rodless cylinder plus slide rail and slider. More specifically, the rodless cylinder and slide rail are both connected to the frame 1, and the connecting plate 413 is connected to the power output end of the rodless cylinder and the slider of the slide rail, and the rodless cylinder drives its longitudinal movement.

[0077] In this embodiment, the longitudinal drive unit 4131 includes a second slide rail 41312, a connecting frame 41313, and a first rodless cylinder 41314. The second slide rail 41312 and the first rodless cylinder 41314 are both connected to the connecting plate 413. A second slider 41315 is provided on the second slide rail 41312. The bottom of the connecting frame 41313 is connected to the second slider 41315. One side of the connecting frame 41313 is connected to the power output end of the first rodless cylinder 41314. The connecting frame 41313 is located behind the pressing unit 414. The pushing module 41311 is symmetrically arranged on the connecting frame 41313.

[0078] In practical use, driven by the first rodless cylinder 41314, the connecting frame 41313 moves along the length of the cylinder. With the cooperation of the second slide rail 41312 and the second slider 41315, the second slide rail 41312 provides a stable path, ensuring that the second slider 41315 moves along a predetermined trajectory. This guiding effect prevents the second slider 41315 from deviating from the track during movement, thereby improving the accuracy and stability of the connecting frame 41313.

[0079] Preferably, the pushing module 41311 includes a double-headed cylinder 41316, a third slide rail 41317, and a connecting block 41318. The double-headed cylinder 41316 is connected to one side of the connecting frame 41313. The third slide rail 41317 is symmetrically arranged on the connecting frame 41313, and each of the third slide rails 41317 is provided with a third slider 41319. The power output ends of the double-headed cylinder 41316 are connected to the connecting block 41318 and the third slider 41319 respectively. The connecting block 41318 is provided with a lifting unit 41320, and the clamping unit 411 is connected to the power output end of the lifting unit 41320 respectively.

[0080] Specifically, the double-acting cylinder 41316 can provide power in both directions, completing reciprocating motion more efficiently than a single-acting cylinder. In other words, the two power outputs of the double-acting cylinder 41316 can simultaneously drive the third slider 41319 located on the third slide rail 41317, causing the clamping units 411 to move closer or further apart. The lifting unit 41320 is used to drive the clamping units 411 to rise and fall. The lifting unit 41320 is a cylinder.

[0081] Furthermore, the clamping unit 414 is provided with a fixing block 4143, the fixing block 4143 is provided with a guide groove 41431 that matches the sleeve and a receiving groove 41432 located at the bottom of the guide groove 41431, one side of the fixing block 4143 is provided with a through groove 41433 that communicates with the receiving groove 41432, the connecting plate 413 is also provided with a pushing unit 4132, the pushing unit 4132 and the through groove 41433 are movably connected, a baffle 41434 is also provided on the top of the frame 1, the top of the fixing block 4143 has a groove 41435 for the baffle 41434 to be inserted, the free end of the baffle 41434 has an inclined surface 41436, the baffle 41434 is used to press down the sleeve located in the fixing block 4143 when the connecting plate 413 moves longitudinally.

[0082] In the initial state, the guide groove 41431 inside the fixed block 4143 is filled with vertically arranged sleeves. When the sleeve conveyor mechanism is a vibratory plate, the vibratory plate is connected to the side of the fixed block 4143 near the top through the conveying pipe and communicates with the guide groove 41431 to convey the sleeves into the guide groove 41431. As the connecting plate 413 moves longitudinally under the drive of the longitudinal drive mechanism 13, the fixed block 4143 will move towards or away from the baffle 41434. When the fixed block 4143 moves towards the baffle 41434, the sleeve first contacts the inclined surface 41436 of the baffle 41434. With the characteristic that the inclined surface 41436 gradually widens, the sleeve located in the guide groove 41431 is gradually pressed down to avoid the sleeve getting stuck in the guide groove 41431.

[0083] In this embodiment, the pushing unit 4132 includes a second rodless cylinder 41321, a bracket 41322, and a push block 41323. One end of the second rodless cylinder 41321 is connected to the connecting plate 413 via the bracket 41322, and the other end of the second rodless cylinder 41321 is connected to one side of the pressing unit 414. The push block 41323 is connected to the power output end of the second rodless cylinder 41321, and the free end of the push block 41323 is movably connected to the through groove 41433.

[0084] When the connecting plate 413 moves backward, it is stationary relative to the push block 41323, but moves relative to the baffle 41434. When the connecting frame 41313 moves backward, it moves relative to the push block 41323, and the sleeve on the push block 41323 falls into the receiving groove 41432. Then the connecting plate 413 resets, and the second rodless cylinder 41321 drives the push block 41323 to move along the through groove 41433, pushing the sleeve in the receiving groove 41432 to the pressing unit 414. The whole process is fully automatic and requires no manual intervention, which is more efficient.

[0085] In this embodiment, the clamping unit 414 includes a support base 4141 connected to the connecting plate 413, a hydraulic cylinder 4142 connected to the top of the support base 4141, and a pressure block 4144 connected to the power output end of the hydraulic cylinder 4142. The support base 4141 is provided with a fixing groove 41411 for fixing the sleeve and limiting blocks 41412 located at both ends of the fixing groove 41411. The limiting blocks 41412 are provided with limiting holes 41413 that match the steel wire. The side of the limiting block 41412 away from the sleeve is provided with a tapered groove 41414. The tapered groove 41414 and the limiting hole 41413 are connected, and the axis of the tapered groove 41414, the axis of the limiting hole 41413, and the axis of the sleeve are on the same straight line. The fixing block 4143 is located on one side of the support base 4141.

[0086] In simple terms, the second rodless cylinder 41321 drives the push block 41323 to move along the through groove 41433, pushing the sleeve located in the receiving groove 41432 into the fixing groove 41411. Subsequently, the push module 41311 drives the clamping unit 411 to move closer to each other, and after the two ends of the steel wire pass through the limiting hole 41413 of the limiting block 41412, they are inserted into the two ends of the sleeve. The hydraulic cylinder 4142 drives the pressure block 4144 to move downward, fixing the two ends of the steel wire inside the sleeve. Because the axis of the limiting hole 41413 and the axis of the sleeve are on the same straight line, as long as the steel wire enters the limiting hole 41413, it can be ensured that the two ends of the steel wire are inserted into the two ends of the sleeve. Moreover, the purpose of the tapered groove 41414 is to guide the wire, which increases the diameter of the inlet end of the limiting hole 41413. As long as the end of the wire enters the tapered groove 41414, under the guiding action of the waist of the tapered groove 41414, the end of the wire can accurately enter the limiting hole 41413.

[0087] Furthermore, the limiting block 41412 includes an upper block 41416, a lower block 41417, a first spring (not shown in the figure) connected between the upper block 41416 and the lower block 41417, and a second spring 41418 connected to the top of the upper block 41416. A vertically arranged guide post 41415 is provided in the support base 4141. The lower block 41417 is connected to both ends of the fixing groove 41411. The upper block 41416 is slidably connected to the guide post 41415, and the upper block 41416 is connected to the bottom of the pressure block 4144 through the second spring 41418. Both the upper block 41416 and the lower block 41417 are provided with recesses. When the upper block 41416 and the lower block 41417 are in contact, the recesses form a limiting hole 41413.

[0088] Specifically, in the initial state, the upper block 41416 and the lower block 41417 are separated. Then, the pressure block 4144 moves downward and presses down the second spring 41418, causing the upper block 41416 to move downward and compress the first spring until the upper block 41416 and the lower block 41417 are in contact. The downward movement stops, and the clamping unit 411 inserts the two ends of the steel wire through the limiting hole 41413 into the sleeve. Then, the pressure block 4144 continues to move downward and press down the sleeve, fixing the two ends of the steel wire in the sleeve. Specifically, the sleeve deforms to fix the steel wire. During the reset process of the pressure block 4144, the first spring resets and pushes the upper block 41416 upward, causing the upper block 41416 and the lower block 41417 to separate. The clamping unit 411 then sends the coiled steel wire to the bending frame device 5.

The upper surface of the receiving rack 61 is inclined, and a swingable blocking mechanism 611 is provided at the lowest point of the upper surface of the receiving rack 61.

A swingable support frame 612 is provided at the highest point of the upper surface of the receiving rack 61. A driving mechanism for driving the support frame 612 to swing is provided inside the receiving rack 61. The driving mechanism can drive the free end of the support frame 612 to enter or leave the bending area b of the external bending frame device 5. When the free end of the support frame 612 enters the bending area b, the upper surface of the support frame 612 is parallel to the upper surface of the receiving rack 61.
