Description

Technical Field

[0001] The utility model relates to the technical field of bed core frame molding, in particular to a bed core frame molding device. Background Art

[0002] The wire frame of the spring core is an important part of the mattress and is usually made of high-strength steel wire. This frame is used to support the springs on the mattress and provide support, allowing the mattress to maintain its shape and provide comfortable support. The wire frame is generally strong and durable, and can effectively disperse the pressure of the body, improving the comfort and support of the mattress.

[0003] CN108188312A A fully automatic mattress spring frame manufacturing device, including a base frame, a bending device is arranged on the outside of the base frame, a straightening wire feeding device, a wire guide rail mechanism and a welding mechanism are arranged on the base frame, the welding mechanism includes a fixed welding part and a movable welding part that moves relative to the fixed welding part, the output end of the straightening wire feeding device is connected with one end of the wire guide rail mechanism, and the other end of the wire guide rail mechanism is connected with the fixed welding part; a first translation mechanism for moving the wire to the movable welding part is arranged on the outside of the straightening wire feeding device, and a second translation mechanism is arranged above the base frame, and the second translation mechanism moves the wire ring after welding to the bending device.

[0004] The above technical solution uses a device to sequentially straighten the steel wire, cut it to a fixed length, weld it into a steel wire ring, and bend the steel wire ring to a fixed length into a mattress steel wire frame. It occupies a small area and has a high degree of intensiveness. It can produce the mattress steel wire frame in an integrated manner at one time, greatly improving production efficiency. However, the above technical solution forms the steel wire ring through the joint action of the steel wire guide mechanism and the welding mechanism. This method cannot ensure the uniform size of the steel wire ring. First, the steel wire guide mechanism has a certain gap between the two arc-shaped guide parts at the bottom, and the steel wire is only subjected to thrust, which is easy to cause uneven stress, so that the steel wire may be deformed or twisted in the arc-shaped guide part; secondly, the welding mechanism forms the steel wire ring by welding, and welding usually requires a certain overlap. During the welding process, local heating may cause thermal expansion of the steel wire. After welding is completed, shrinkage may occur during the cooling process, resulting in obvious inconsistency in the length of some steel wire rings after welding. Utility Model Content

[0005] The utility model aims to solve the above-mentioned problems and provides a bed core frame forming device. The forming device clamps one end of the steel wire through a bending circle mechanism to swing in a circle and cooperates with the clamping and conveying mechanism to clamp the other end of the cut steel wire and convey it backwards so that the two ends of the steel wire are relative to each other, ensuring the fixed length of the steel wire for each bending circle, and can more accurately control the bending process of the steel wire to ensure the quality and accuracy of the bending circle. The two ends of the steel wire are clamped by the clamping unit and inserted into the sleeve of the sleeve connecting mechanism for connection, which can avoid the problem of obvious inconsistency in the length of some steel wire circles caused by welding. Finally, under the action of the clamping unit, the coiled steel wire is sent to the bending frame device for bending, ensuring the uniformity of the size of each steel wire circle, and the straightening and feeding device, the cutting device, the bending circle forming device, and the bending frame device are integrated together, occupying a small area.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] refer to Figures 1 to 11 A bed core frame forming device, comprising a frame 1, a straightening and feeding device 2, a cutting device 3, a bending and forming device 4, and a bending frame device 5 located on the frame 1, wherein the cutting device 3 is connected to the straightening and feeding device 2, the bending and forming device 4 and the bending frame device 5 are arranged opposite to each other, the bending and forming device 4 comprises a sleeve connecting mechanism 41 arranged opposite to the bending frame device 5, a clamping and conveying mechanism 42 located between the sleeve connecting mechanism 41 and the bending frame device 5, and a bending and forming mechanism 43 connected to one side of the frame 1, and a symmetrically arranged clamping unit 411 is provided on the sleeve connecting mechanism 41;

[0027] The bending mechanism 43 is used to clamp one end of the steel wire and make a circular swing to bend it. The clamping and conveying mechanism 42 is used to clamp the other end of the cut steel wire and convey it backwards so that the two ends of the steel wire are opposite to each other. The clamping unit 411 is used to clamp the two ends of the steel wire and insert them into the sleeve of the sleeve connecting mechanism 41 to connect the two ends of the steel wire, and convey it to the bending frame device 5 through the clamping unit 411 for bending.

[0028] Under this design, the steel wire first passes through the straightening and feeding device 2 for straightening, 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 in a circle. When the bending mechanism 43 swings to a 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, and cooperates with the bending mechanism 43 to swing to the initial position, so that the two ends of the steel wire are opposite to each other; then the clamping unit 411 clamps the two ends of the steel wire, and inserts the two ends of the steel wire into the sleeve of the sleeve connecting mechanism 41, so that the two ends of the steel wire are connected, and are conveyed to the bending frame device 5 through the clamping unit 411 for bending.

[0029] In this way, the fixed length of the steel wire can be guaranteed for each bending circle, and the bending process of the steel wire can be controlled more accurately to ensure the quality and accuracy of the bending circle. At the same time, the problem of obvious inconsistency in the length of some steel wire circles caused by welding can be avoided, and the size uniformity of each steel wire circle can be ensured. The straightening and feeding device 2, the cutting device 3, the bending circle forming device 4, and the bending frame device 5 are integrated together, occupying a small area.

[0030] It should be noted that the wire straightening and feeding device 2, the cutting device 3, and the bending frame device 5 have been recorded in Chinese patent CN108188312A, so the structures of the wire straightening and feeding device 2, the cutting device 3, and the bending frame device 5 are not described in detail in this embodiment.

[0031] Preferably, the clamping and conveying mechanism 42 includes a transverse driving unit 421 connected to the frame 1, a support plate 422 connected to the transverse driving unit 421, a lifting module 423 connected to the support plate 422, and a first pneumatic clamp 424 connected to the power output end of the lifting module 423. The support plate 422 is provided with a first slide rail 4221, a first slider 4222 connected to the first slide rail 4221, and one side of the first pneumatic clamp 424 is connected to the first slider 4222.

[0032] Specifically, when the bending mechanism 43 swings to a preset position, the first pneumatic clamp 424 clamps the steel wire, and after the cutting device 3 cuts the steel wire, the transverse drive unit 421 drives the first pneumatic clamp 424 to move backward, and cooperates with the bending mechanism 43 to swing to an initial state, so that the two ends of the steel wire are opposite to each other; then the lifting module 423 drives the first pneumatic clamp 424 to descend and reset under the drive of the transverse drive unit 421, so as to prevent the first pneumatic clamp 424 from affecting the action 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 action of the first pneumatic clamp 424 can be guaranteed.

[0033] In this embodiment, the bending mechanism 43 includes a swing arm 431 and a second pneumatic clamp 432. A rotation drive mechanism 11 is provided in the frame 1. One end of the swing arm 431 is connected to the rotation drive mechanism 11. The second pneumatic clamp 432 is connected to the other end of the swing arm 431. The rotation drive mechanism 11 drives the swing arm 431 to swing so that the second pneumatic clamp 432 swings in a circle. A drive module 12 for driving the second pneumatic clamp 432 to clamp or release is also provided on the frame 1.

[0034] When one end of the steel wire reaches the position of the second pneumatic clamp 432, the driving module 12 drives the second pneumatic clamp 432 to move and clamp one end of the steel wire. Then, under the drive of the rotating drive mechanism 11, the swing arm 431 rotates and drives the second pneumatic clamp 432 to swing in a circle to bend the steel wire. In this way, the bending process of the steel wire can be controlled more accurately to ensure the quality and accuracy of the bending.

[0035] In this embodiment, the sleeve connecting 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 driving mechanism 13. The connecting plate 413 is connected to the longitudinal driving mechanism 13. The clamping unit 414 is connected to the connecting plate 413. The connecting plate 413 is provided with a longitudinal driving unit 4131. The longitudinal driving unit 4131 is provided with symmetrically arranged pushing modules 41311. The clamping units 411 are respectively connected to the pushing modules 41311 and are located on both sides of the clamping unit 414. The pushing modules 41311 are used to drive the clamping units 411 to move closer to or away from each other. The sleeve conveying unit 412 is used to convey the sleeve to the clamping unit 414.

[0036] Specifically, the longitudinal driving mechanism 13 is used to drive the connecting plate 413 to move forward and backward in the longitudinal direction. Under the drive of the longitudinal driving unit 4131, the clamping unit 411 moves toward the steel wire and clamps the two ends of the steel wire. The sleeve conveying unit 412 conveys the sleeve to the clamping unit 414. Then, the longitudinal driving unit 4131 drives the clamping unit 411 to move backward so that the two ends of the steel wire are aligned with the sleeve on the clamping unit 414, and under the drive of the pushing module 41311, the clamping unit 411 is driven to approach each other and insert the two ends of the steel wire into the sleeve. The two ends of the steel wire are pressed in the sleeve by the clamping unit 414. Then, the longitudinal driving unit 4131 drives the clamping unit 411 to convey the steel wire to the bending frame device 5.

[0037] In this embodiment, the longitudinal driving 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. The second slide rail 41312 is provided with a second slider 41315. 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 clamping unit 414, and the pushing module 41311 is symmetrically arranged on the connecting frame 41313.

[0038] In actual use, driven by the first rodless cylinder 41314, the connecting frame 41313 moves along the length direction of the first rodless cylinder 41314. With the cooperation of the second slide rail 41312 and the second slider 41315, the second slide rail 41312 provides a stable path to ensure that the second slider 41315 moves along a predetermined track during movement. This guiding effect can prevent the second slider 41315 from deviating from the track during movement, thereby improving the accuracy and stability of the connecting frame 41313.

[0039] 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. The third slide rail 41317 is provided with a third slider 41319. The power output end of the double-headed cylinder 41316 is respectively connected through the connecting block 41318 and the third slider 41319. The connecting block 41318 is provided with a lifting unit 41320, and the clamping unit 411 is respectively connected to the power output end of the lifting unit 41320.

[0040] Specifically, the double-headed cylinder 41316 can provide power in both directions and can complete the reciprocating motion more effectively than the single-acting cylinder, that is, the two power output parts of the double-headed cylinder 41316 can simultaneously drive the third slider 41319 located on the third slide rail 41317 to move, so that the clamping units 411 move closer to or farther from each other. The lifting unit 41320 is used to drive the clamping unit 411 to rise and fall.

[0041] Furthermore, the clamping unit 414 is provided with a fixing block 4143, the fixing block 4143 is provided with a guide groove 41431 matching 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 connected to the receiving groove 41432, and the connecting plate 413 is also provided with a pushing unit 4132, the pushing unit 4132 and the through groove 41433 are movably connected, and a baffle 41434 is also provided on one side of the entrance end of the guide groove 41431, and the baffle 41434 is used to prevent the sleeve from entering the guide groove 41431.

[0042] In the initial state, the baffle 41434 blocks the output end of the sleeve conveying unit 412. When the longitudinal driving mechanism 13 drives the connecting plate 413 to move backward longitudinally, the baffle 41434 gradually moves away from the sleeve conveying unit 412 until the fixed block 4143 and the output end of the sleeve conveying unit 412 are connected. The sleeve enters the guide groove 41431 and falls into the accommodating groove 41432. The longitudinal driving mechanism 13 drives the frame 1 to reset, and the pushing unit 4132 pushes the sleeve from the through groove 41433 into the clamping unit 414.

[0043] 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 through the bracket 41322, and the other end of the second rodless cylinder 41321 is connected to one side of the clamping 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.

[0044] When the connecting plate 413 moves backward, the connecting plate 413 is stationary relative to the push block 41323, and when the connecting frame 41313 moves backward, the connecting frame 41313 is moving relative to the push block 41323, that is, when the baffle 41434 is located on one side of the sleeve conveying unit 412, and the guide groove 41431 is connected with the output end of the sleeve conveying unit 412, the sleeve will enter the guide groove 41431 from the output end of the sleeve conveying unit 412 and fall into the accommodating groove 41432; then the connecting plate 413 is reset, and the push block 41323 is driven by the second rodless cylinder 41321 to move along the direction of the through groove 41433, and the sleeve in the accommodating groove 41432 is pushed to the clamping unit 414. The whole process is fully automatic, without manual intervention, and more efficient.

[0045] More preferably, the clamping unit 414 includes a support seat 4141 connected to the connecting plate 413, a cylinder 4142 connected to the top of the support seat 4141, and a pressing block 4143 connected to the power output end of the cylinder 4142. The support seat 4141 is provided with a fixing groove 41411 for fixing the sleeve, and limit blocks 41412 are located at both ends of the fixing groove 41411. The limit blocks 41412 are provided with limit holes 41413 matching the steel wire. A conical groove 41414 is provided on the side of the limit block 41412 away from the sleeve. The conical groove 41414 and the limit hole 41413 are connected, and the axis of the conical groove 41414, the axis of the limit hole 41413, and the axis of the sleeve are located on the same straight line. The fixing block 4143 is located on one side of the support seat 4141.

[0046] In simple terms, the second rodless cylinder 41321 drives the push block 41323 to move along the through slot 41433, and pushes the sleeve in the receiving slot 41432 into the fixing slot 41411, and then the push module 41311 drives the clamping unit 411 to approach each other, and inserts the two ends of the steel wire into the two ends of the sleeve after passing through the limiting hole 41413 of the limiting block 41412, and then the oil cylinder 4142 drives the pressing block 4143 downward to fix the two ends of the steel wire in the sleeve. Because the axis of the limiting hole 41413 and the axis of the sleeve are in 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, which increases the aperture of the entrance end of the limiting hole 41413. As long as the end of the steel wire enters the tapered groove 41414, the end of the steel wire can accurately enter the limiting hole 41413 under the guiding effect of the waist of the tapered groove 41414.

[0047] Furthermore, the limit block 41412 includes an upper block 41416, a lower block 41417, a first spring 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 column 41415 is provided in the support seat. The lower block 41417 is connected to both ends of the fixed groove 41411. The upper block 41416 is slidably connected to the guide column 41415, and the upper block 41416 is connected to the bottom of the pressure block 4143 through the second spring 41418. The upper block 41416 and the lower block 41417 are both provided with recesses. When the upper block 41416 and the lower block 41417 are fitted together, the recesses form the limit holes 41413.

[0048] Specifically, in the initial state, the upper block 41416 and the lower block 41417 are in a separated state, and then the pressure block 4143 moves downward and presses down the second spring 41418, so that the upper block 41416 moves downward and compresses the first spring until the upper block 41416 and the lower block 41417 fit together and stop moving downward. The clamping unit 411 inserts the two ends of the steel wire into the sleeve through the limiting hole 41413, and then the pressure block 4143 continues to move downward and presses down the sleeve to fix the two ends of the steel wire in the sleeve. During the resetting process of the pressure block 4143, the first spring resets and pushes the upper block 41416 upward, so that the upper block 41416 and the lower block 41417 are separated, and the clamping unit 411 sends the coiled steel wire to the bending frame device 5.

[0049] In this embodiment, a material receiving rack 6 is further provided on one side of the frame 1, and the material receiving rack 6 is located below the frame bending device 5. The purpose of the material receiving rack 6 is to collect the steel wire frame after the frame bending is completed.

[0050] The working process of this equipment is:

[0051] The steel wire first passes through the straightening and feeding device 2 for straightening, and then passes through the cutting device 3 and the first pneumatic clamp 424 in sequence. When the end of the steel wire reaches the second pneumatic clamp 432, the driving module drives the second pneumatic clamp 432 to clamp one end of the steel wire, and the rotary drive mechanism 11 drives the swing arm 431 to rotate and make the second pneumatic clamp 432 swing in a circle. When the second pneumatic clamp 432 swings to a preset angle, the first pneumatic clamp 424 clamps the steel wire. After the cutting device 3 cuts the steel wire, the transverse drive unit 421 drives The first pneumatic clamp 424 drives the other end of the steel wire to move backward, and cooperates with the second pneumatic clamp 432 to swing to the initial position, so that the two ends of the steel wire are opposite to each other, and the longitudinal drive mechanism 13 drives the clamping unit 414 to move backward in the longitudinal direction, so that the fixed block 4143 and the output end of the sleeve conveying unit 412 are connected, so that the sleeve enters the guide groove 41431 and falls into the receiving groove 41432. The longitudinal drive mechanism 13 drives the clamping unit 414 to reset, and drives the push block 41323 to move through the second rodless cylinder 41321. Push the sleeve in the receiving groove 41432 into the fixing groove 41411, then the first rodless cylinder 41314 drives the clamping unit 411 to move forward in the longitudinal direction and clamp the two ends of the steel wire, and then align with the limiting hole 41413 in the limiting block 41412, and the double-headed cylinder 41316 drives the clamping units 411 to move closer to each other, and the pressing block 4143 moves downward and presses down the second spring 41418, so that the upper block 41416 moves downward and compresses the first spring until the upper block 41416 and the lower block 41417 fit together. , stops descending, the clamping unit 411 inserts the two ends of the steel wire into the sleeve through the limiting hole 41413, and then the pressing block 4143 continues to descend and presses down the sleeve to fix the two ends of the steel wire in the sleeve. During the resetting process of the pressing block 4143, the first spring resets and pushes the upper block 41416 upward to separate the upper block 41416 and the lower block 41417. The driving unit 41320 drives the clamping unit 411 to rise, and sends the coiled steel wire to the bending frame device 5 through the first rodless cylinder 41314.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
