[0002] The wire frame of the spring core is an important part of the mattress and is usually made of high-strength steel wire.

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 10 A steel wire casing connection device comprises a frame 1, a pressing mechanism 2, and a clamping mechanism 3. The frame 1 is provided with a symmetrically arranged first pushing mechanism 11, and the clamping mechanisms 3 are respectively connected to the first pushing mechanism 11. The clamping mechanism 3 is used to clamp the two ends of the steel wire. The first pushing mechanism 11 is used to drive the clamping mechanism 3 to move laterally so that the clamping mechanism 3 is close to or away from the first pushing mechanism 11.

[0027] The clamping mechanism 2 is connected to the frame 1, and the clamping mechanism 2 is located between the clamping mechanisms 3;

[0028] The external sleeve conveying device conveys the sleeve 5 to the clamping mechanism 2, and drives the clamping mechanism 3 to approach through the first pushing mechanism 11, inserting the two ends of the steel wire into the sleeve 5, and the clamping mechanism 2 presses down the sleeve 5 to fix the two ends of the steel wire in the sleeve 5.

[0029] In this design, after the steel wire is bent by the external bending device, the external sleeve conveying device conveys the sleeve 5 to the clamping mechanism 2, and the two ends of the steel wire are clamped by the clamping mechanism 3. Then the first pushing mechanism 11 drives the clamping mechanism 3 to approach, and the clamping mechanism 3 inserts the steel wire into the sleeve 5 of the clamping mechanism 2. The clamping mechanism 2 presses down to fix the two ends of the steel wire in the sleeve 5, and the steel wire ring is formed. Finally, the first pushing mechanism 11 drives the clamping mechanism 3 to reset. In this way, fatigue fracture caused by welding during the bending process can be avoided, and the yield rate can be improved.

[0030] It should be noted that the external bending device can be a wire guide mechanism disclosed in Chinese patent CN108188312A. The clamping mechanism 3 of the utility model can adopt a pneumatic clamping jaw 31.

[0031] In this embodiment, a first horizontal driving mechanism 4 is also included, the first horizontal driving mechanism 4 is connected to the frame 1, the first pushing mechanism 11 is symmetrically arranged on the first horizontal driving mechanism 4, and the first horizontal driving mechanism 4 is used to drive the clamping mechanism 3 to move longitudinally. Under the action of the first horizontal driving mechanism 4, after the steel wire is bent, the clamping mechanism 3 can be driven to move longitudinally, that is, to move in the direction of the steel wire and clamp the steel wire, so that the clamping mechanism 3 can be prevented from obstructing the work of the peripheral bending device.

[0032] Furthermore, the first horizontal driving mechanism 4 includes a first slide rail 41, a connecting frame 42, and a first rodless cylinder 43. The first slide rail 41 and the first rodless cylinder 43 are both connected to the frame 1. The first slide rail 41 is provided with a first slider 411. The bottom of the connecting frame 42 is connected to the first slider 411. One side of the connecting frame 42 is connected to the power output end of the first rodless cylinder 43. The connecting frame 42 is located behind the clamping mechanism 2, and the first pushing mechanism 11 is symmetrically arranged on the connecting frame 42.

[0033] Specifically, the first rodless cylinder 43 drives its power output end to move, and drives the connecting frame 42 and the first pushing mechanism 11 on the connecting frame 42 to move, so that the clamping mechanism 3 moves forward or backward in the longitudinal direction. At the same time, we found that by adding the first slide rail 41 and the first slider 411, the first slide rail 41 provides a stable path to ensure that the first slider 411 moves along a predetermined track during movement. This guiding effect can prevent the first slider 411 from deviating from the track during movement, thereby improving the accuracy and stability of the connecting frame 42. In addition, the connecting frame 42 is located behind the clamping mechanism 2, and the clamping mechanism 2 can also provide a limiting function for the connecting frame 42, that is, when the connecting frame 42 and the clamping mechanism 2 are in contact, the clamping mechanism 3 reaches the preset position.

[0034] In this embodiment, it also includes a machine table 6, on which a second horizontal driving mechanism 61 is provided, and the frame 1 is connected to the second horizontal driving mechanism 61, and the second horizontal driving mechanism 61 is used to drive the frame 1 to move longitudinally. The frame 1 is also provided with a sleeve conveying mechanism 12, and the frame 1 is also provided with a second pushing mechanism 13; the sleeve conveying mechanism 12 is used to convey the sleeve 5 to the clamping mechanism 2, and the second pushing mechanism 13 is used to push the sleeve 5 into the clamping mechanism 2.

[0035] In actual use, the second horizontal driving mechanism 61 is used to drive the frame 1 and the clamping mechanism 2 connected to the frame 1 to move longitudinally, so that the clamping mechanism 2 and the sleeve conveying mechanism 12 are docked, and the sleeve 5 is conveyed to the clamping mechanism 2 through the sleeve conveying mechanism 12, and then the sleeve 5 is pushed into the clamping mechanism 2 under the action of the second pushing mechanism 13.

[0036] Preferably, the clamping mechanism 2 is provided with a fixing block 213, the fixing block 213 is provided with a guide groove 2131 matching the sleeve 5, and a receiving groove 2132 located at the bottom of the guide groove 2131, a through groove 2133 communicating with the receiving groove 2132 is provided on one side of the fixing block 213, the second pushing mechanism 13 is movably connected to the through groove 2133, and a baffle 2134 is further provided on one side of the entrance end of the guide groove 2131, and the baffle 2134 is used to prevent the sleeve 5 from entering the guide groove 2131;

[0037] Specifically, in the initial state, the baffle 2134 blocks the output end of the sleeve conveying mechanism 12. When the second horizontal driving mechanism 61 drives the frame 1 to move backward in the longitudinal direction, the baffle 2134 gradually moves away from the sleeve conveying mechanism 12 until the fixed block 213 and the output end of the sleeve conveying mechanism 12 are connected. The sleeve 5 enters the guide groove 2131 and falls into the accommodating groove 2132. The second horizontal driving mechanism 61 drives the frame 1 to reset, and the second pushing mechanism 13 pushes the sleeve 5 into the clamping mechanism 2 from the through groove 2133.

[0038] Furthermore, the second pushing mechanism 13 includes a second rodless cylinder 131, a bracket 132, and a connecting block 133. One end of the second rodless cylinder 131 is connected to the frame 1 through the bracket 132, and the other end of the second rodless cylinder 131 is connected to one side of the clamping mechanism 2. The connecting block 133 is connected to the power output end of the second rodless cylinder 131, and the free end of the connecting block 133 is movably connected to the through groove 2133.

[0039] Specifically, when the frame 1 moves backward, the frame 1 is stationary relative to the connecting block 133, and when the connecting frame 42 moves backward, the connecting frame 42 moves relative to the connecting block 133, that is, when the baffle 2134 is located on one side of the sleeve conveying mechanism 1212, and the guide groove 2131 is connected to the output end of the sleeve conveying mechanism 12, the sleeve 5 will enter the guide groove 2131 from the output end of the sleeve conveying mechanism 12 and fall onto the accommodating groove 2132; then the frame 1 is reset, and the connecting block 133 is driven by the second rodless cylinder 131 to move along the direction of the through groove 2133, and the sleeve 5 in the accommodating groove 2132 is pushed to the clamping mechanism 2. The whole process is fully automatic, without manual intervention, and more efficient.

[0040] In this embodiment, the clamping mechanism 2 includes a support seat 21 connected to the frame 1, a cylinder 22 connected to the top of the support seat 21, and a pressure block 23 connected to the power output end of the cylinder 22. The support seat 21 is provided with a fixing groove 211 for fixing the sleeve 5, and limit blocks 212 are located at both ends of the fixing groove 211. The limit block 212 is provided with a limit hole 2121 matching the steel wire, and the axis of the limit hole 2121 and the axis of the sleeve 5 are located in the same straight line. The pressure block 23 is located above the fixing groove 211, and the fixing block 213 is located on one side of the support seat 21.

[0041] In actual use, the second rodless cylinder 131 drives the connecting block 133 to move along the through groove 2133, and pushes the sleeve 5 located in the receiving groove 2132 into the fixing groove 211, and then the first pushing mechanism 11 drives the clamping mechanism 3 to approach each other, and inserts the two ends of the steel wire into the two ends of the sleeve 5 after passing through the limiting hole 2121 of the limiting block 212, and then the oil cylinder 22 drives the pressing block 23 downward to fix the two ends of the steel wire in the sleeve 5. Because the axis of the limiting hole 2121 and the axis of the sleeve 5 are located in the same straight line, as long as the steel wire enters the limiting hole 2121, it can be ensured that the two ends of the steel wire are inserted into the two ends of the sleeve 5.

[0042] As a further optimization of this embodiment, a conical groove 2122 is provided on the side of the limiting block 212 away from the sleeve 5, the conical groove 2122 is connected to the limiting hole 2121, and the axis of the conical groove 2122 and the axis of the limiting hole 2121 are located in the same straight line.

[0043] Simply put, the purpose of the tapered groove 2122 is to guide, which increases the aperture of the entrance end of the limiting hole 2121. As long as the end of the steel wire enters the tapered groove 2122, the end of the steel wire can accurately enter the limiting hole 2121 under the guiding effect of the waist of the tapered groove 2122.

[0044] Optionally, the limit block 212 includes an upper block 2124, a lower block 2125, a first spring (not shown in the figure) connected between the upper block and the lower block, and a second spring 2126 connected to the top of the upper block 2124. A vertically arranged guide column 214 is provided in the support seat 21, the lower block 2125 is connected to both ends of the fixed groove 211, the upper block 2124 is slidably connected to the guide column 214, and the upper block 2124 is connected to the bottom of the pressure block 23 through the second spring 2126. The upper block 2124 and the lower block 2125 are both provided with recesses. When the upper block 2124 and the lower block 2125 are in contact, the recess forms a limit hole 2121.

[0045] Specifically, in the initial state, the upper block 2124 and the lower block 2125 are in a separated state, and then the pressure block 23 moves downward and presses down the second spring 2126, so that the upper block 2124 moves downward and compresses the first spring until the upper block 2124 and the lower block 2125 fit together and stop moving downward. The clamping mechanism 3 inserts the two ends of the steel wire into the sleeve 5 through the limiting hole 2121, and then the pressure block 23 continues to move downward and presses down the sleeve 5 to fix the two ends of the steel wire in the sleeve 5. During the resetting process of the pressure block 23, the first spring resets and pushes the upper block 2124 upward, so that the upper block 2124 and the lower block 2125 are separated, and the clamping mechanism 3 sends the coiled steel wire to the external bending frame device.

[0046] Preferably, the first pushing mechanism 11 includes a double-headed cylinder 111, a second slide rail 112, and a connecting plate 113. The double-headed cylinder 111 is connected to one side of the connecting frame 42. The second slide rail 112 is symmetrically arranged on the connecting frame 42. The second slide rail 112 is provided with a second slider 1121. The power output end of the double-headed cylinder 111 is respectively connected to the second slider 1121 through the connecting plate 113. A lifting module 1131 is provided on the connecting plate 113. The clamping mechanism 3 is respectively connected to the power output end of the lifting module 1131.

[0047] The double-headed cylinder 111 can provide power in both directions and can complete reciprocating motion more effectively than a single-acting cylinder. That is, the two power output parts of the double-headed cylinder 111 can simultaneously drive the second slider 1121 located on the second slide rail 112 to move, so that the clamping mechanism 3 moves closer to or farther from each other. The lifting module 1131 is used to raise or lower the clamping mechanism 3 so that the clamping mechanism 3 can separate the steel wire from the lower block 2125.

[0048] 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.
