Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a long-row hinged production line. Background Technology

[0002] Long-row hinges in the existing technology are characterized by high load capacity and durability, and are widely used as hinges in pianos and large doors and windows.

[0003] The existing fabrication process for long row hinges is as follows:

[0004] The long strip of steel coil is divided into two serrated strips with staggered serrations along its length by a slitting die. Then, a portion of the edge of the serrated part of one of the serrated strips is cut off by an edge trimming die. The two serrated strips are then processed by a spool wrapping process, in which the serrated part is bent and wrapped around the same steel spool, thus producing the long row of hinges.

[0005] During the conveying and movement process, the two sawtooth strips experience different frictional resistances, which causes the gap between the two sawtooth strips wrapped on the steel spool to be squeezed. This causes the two sawtooth strips to abut against each other and become misaligned in the length direction, resulting in insufficient rotational flexibility of the produced long row hinge and affecting the quality of the output long row hinge. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal communication between two components.

[0060] A long-row hinge production line includes a feeding device 10, and a material separating and trimming device 1, a bobbin wrapping device 2, a flattening device 4, a punching device 6 and a cutting device 7 arranged sequentially on a worktable 100 in a back-to-forward running direction. It also includes a pressing device 8 and a pulling device 9.

[0061] The pressing device 8 includes a pressing assembly 81 and a support wheel 83; the pressing assembly 81 includes a pressing cylinder 811 and a pressing rod 812.

[0062] The support wheel 83 is mounted between the bobbin wrapping device 2 and the flattening device 4. The top surface of the support wheel 83 is used to support the long row of hinged material 101 passing from above. The pressing cylinder 811 is installed above the support wheel 83. The upper end of the pressing rod 812 is connected to the pressing cylinder 811. The lower end of the pressing rod 812 extends downward and backward and is close to the top surface of the support wheel 83. The bottom surface of the pressing rod 812 is used to press downward against the plate surface of the long row of hinged material 101, and the rear side of the bottom surface of the pressing rod 812 is used to press against the front side of the serration of a serrated strip in the long row of hinged material 101.

[0063] The material pulling device 9 is installed between the flattening device 4 and the punching device 6. The operating rhythm of the material pulling device 9 is the same as that of the pressing device 8. The material pulling device 9 is used to pull forward and convey the long row of hinged material 101.

[0064] Figure 1 This is a schematic diagram of the wiring structure of one embodiment of a long-row hinge production line according to the present invention. Figure 2 The structure of the pressing device 8 is shown in the figure.

[0065] like Figure 1 As shown, the long strip of steel strip is unwound by the feeding device 10 and fed into the material separating and cutting device 1. The material separating die of the material separating and cutting device 1 cuts the steel strip along its length and divides it into two serrated strips with staggered serrations. Then, the cutting die of the material separating and cutting device 1 removes a portion of the edge of the serrated part of one of the serrated strips. The two serrated strips are then bent by the spool wrapping device 2 and wrapped around the same steel wire to form a long row of hinges 101. The long row of hinges 101 is shaped by the flattening device 4 in a flat state, and then punched with fastener mounting holes in the punching device 6. Finally, the cutting device 7 cuts the long row of hinges 101 to the set length, thus completing the processing and forming of the long row of hinges.

[0066] The edge of the serrated portion of one of the strips is removed by the cutting die of the material cutting device 1. The purpose is to avoid interference between the two serrated strips wrapped with the same steel wire in the long row of hinges when they rotate.

[0067] During the conveying and movement of the long row of hinge material 101 from back to front, the different frictional resistance experienced by the two sawtooth strips will cause the gap between the two sawtooth strips to be squeezed, causing the two sawtooth strips to abut against each other and become misaligned in the length direction, resulting in the rotational flexibility of the manufactured long row of hinges failing to meet the quality requirements.

[0068] If not corrected in time, the serrated edge that is bent and wrapped around the steel wire will be compacted when passing through the flattening device 4, requiring manual rework to correct the misalignment, which will lead to an increase in manufacturing costs.

[0069] like Figure 1 and Figure 2 As shown, the pressing cylinder 811 drives the pressing rod 812 to move up and down reciprocally according to the set rhythm. The rear edge of the bottom surface of the pressing rod 812 abuts against the front edge of the serration of one of the serrated strips in the long row of hinged material 101 to be flattened, thereby correcting the gap between the two serrated strips in the long row of hinged material 101 to be flattened, thus correcting the misalignment. At the same time, the pulling device 9, which has the same operating rhythm as the pressing device 8, pulls and conveys the long row of hinged material 101 to be flattened forward, so that the long row of hinged material 101, which has completed the misalignment correction, is shaped in the flattening device 4.

[0070] Furthermore, the pressing device 8 also includes a brake assembly 82;

[0071] The brake assembly 82 includes a brake wheel 821, a swing arm 822, a rotating wheel 823, and a tension spring 824;

[0072] The pressing cylinder 811 and the rotating wheel 823 are respectively installed above the support wheel 83, and the pressing cylinder 811 and the rotating wheel 823 are spaced apart from each other.

[0073] The rear end of the swing arm 822 is inserted into the rotating wheel 823, and the brake wheel 821 is rotatably mounted on the front end of the swing arm 822. The brake wheel 821 is located directly above the support wheel 83. The lower end of the tension spring 824 is fixed to the lower part of the support wheel 83, and the upper end of the tension spring 824 is hooked to the rotating shaft of the brake wheel 821.

[0074] The brake wheel 821 is located behind the pressing rod 812, and the bottom surface of the brake wheel 821 is used to press down against the surface of the long row of hinged material 101 to be flattened.

[0075] like Figure 2 As shown, when the rotating wheel 823 rotates, the brake wheel 821 moves downward through the cooperation of the swing arm 822, the rotating wheel 823 and the tension spring 824, so that the bottom surface of the brake wheel 821 abuts against the top surface of the long row of hinged material 101 to be flattened, thereby reducing the forward movement speed of the long row of hinged material 101 to be flattened, which can reduce the impact force when the pressing rod 811 contacts the long row of hinged material 101, thereby reducing the deformation and wear of the pressing rod 811.

[0076] Furthermore, the material pulling device 9 includes a drive motor 91, a mounting base 92, a transmission gear 93, a transmission rod 98, two driven gears 94, two lifting wheels 96, two driven rollers 97, two driven rods 99, and two lifting cylinders 95;

[0077] The drive motor 91 and the mounting base 92 are mounted on the worktable 100 with a left-right gap, and are located between the flattening device 4 and the punching device 6;

[0078] The mounting base 92 has a first mounting groove 921; the first mounting groove 921 is recessed downwards into the top surface of the mounting base 92 and extends through the mounting base 92 from front to back; two lifting cylinders 95 are mounted on the top of the first mounting groove 921 at a distance from front to back, the output end of the lifting cylinder 95 extends downwards into the first mounting groove 921, and the lifting wheel 96 is hung on the output end of the lifting cylinder 95; the drive motor 91 is close to the side of the mounting base 92 and is located below the lifting cylinder 95;

[0079] The transmission rod 98 and the two driven rods 99 pass through the mounting base 92 from left to right and through the first mounting groove 921. The transmission rod 98 is located between the two driven rods 99. One end of the transmission rod 98 is connected to the output end of the drive motor 91, and the transmission gear 93 is fitted onto the other end of the transmission rod 98. The driven gear 94 is fitted onto the end of the driven rod 99 away from the drive motor 91, and the two driven gears 94 mesh with the transmission gear 93 respectively. The driven roller 97 is rotatably fitted onto the outer circumferential surface of the rod body of the driven rod 99 located in the first mounting groove 921, and the two driven rollers 97 are aligned vertically with the two lifting wheels 96 respectively.

[0080] The lifting wheel 96 is used to press the long row of hinged material 101 onto the top surface of the corresponding driven roller 97 from top to bottom.

[0081] like Figure 1-3 As shown, when the punch in the punching device 6 punches the long row of reamed material 101, or when the cutting die in the cutting device 7 cuts the long row of reamed material 101 downwards, the two lifting cylinders 95 start synchronously and drive the two lifting wheels 96 to press the long row of reamed material 101 from top to bottom onto the top surface of the corresponding driven roller 97. This can prevent the punching position from being misaligned due to the movement of the long row of reamed material 101, or the cutting point of the long row of reamed material 101 from being misaligned, thereby improving the processing quality of the long row of reamed material 101.

[0082] After the long row of hinged material 101 completes one punching or one cutting action, the two lifting cylinders 95 close and drive the two lifting wheels 96 to rise synchronously. At the same time, the drive motor 91 starts and drives the transmission gear 93 to rotate. The transmission gear 93 drives the two driven gears 94 to rotate, which in turn drives the long row of hinged material 101 to move forward one step.

[0083] Furthermore, it also includes a metering gear 11;

[0084] The metering gear 11 is installed close to the front of the material distribution and trimming device 1;

[0085] The metering gear 11 is provided with a plurality of protruding teeth 111, which are arranged at equal intervals on the outer periphery of the metering gear 11. The protruding teeth 111 are used to insert into the gap between the teeth of the sawtooth strips output from the material cutting device 1.

[0086] like Figure 1 As shown, by inserting multiple protruding teeth 111 into the gap between the teeth of the sawtooth strip in sequence, the metering gear 11 can rotate synchronously with the forward-moving sawtooth strip. By calculating the circumference of the rotation of the metering gear 11, the length of the steel strip coil that has been divided by the material dividing and trimming device 1 can be obtained.

[0087] Furthermore, it also includes the first shaping component 3;

[0088] The first shaping component 3 includes a first mounting plate 31, a plurality of first shaping wheels 32 and a plurality of first rotating shafts 33;

[0089] The first mounting plate 31 is mounted on the workbench 100, and the first mounting plate 31 is located between the rotating wheel 823 and the bobbin wrapping device 2;

[0090] One end of the first rotating shaft 33 is fixed to the first mounting plate 31, and the other end of the first rotating shaft 33 extends in the horizontal direction; the plurality of first rotating shafts 33 are divided into two groups, the first rotating shafts 33 in the same group are arranged on the same horizontal line, and the plurality of first rotating shafts 33 are spaced apart vertically and staggered front and back.

[0091] The first shaping wheel 32 is rotatably mounted on the other end of the first rotating shaft 33. The top surface of the lower first shaping wheel 32 is on the same horizontal plane as the top surface of the support wheel 83, and the bottom surface of the upper first shaping wheel 32 is lower than the top surface of the support wheel 83. The gap between the two upper and lower first rotating shafts 33 is arranged in a curve along the front-back direction to form the first shaping channel.

[0092] like Figure 1 and Figure 2 As shown, the long row of spools 101, which has completed the wrapping of the spool, passes through the first shaping channel. The wheel surfaces of multiple first shaping wheels 32 act sequentially on the long row of spools 101, causing the long row of spools 101 to bend up and down within the elastic range, so that the wrapped steel wire spool can rotate flexibly, thereby ensuring the rotational performance of the output long row of spools.

[0093] Furthermore, it also includes a second shaping component 5;

[0094] The second shaping assembly 5 includes a guide plate 51, a plurality of second mounting plates 52, a plurality of second shaping wheels 53 and a plurality of second rotating shafts 54;

[0095] The guide plate 51 is mounted on the workbench 100. The guide plate 51 extends in the front-to-back direction and is located between the mounting base 92 and the flattening device 4. The guide plate 51 is provided with a guide groove 511 and a plurality of second mounting grooves 512. The guide groove 511 extends in the front-to-back direction and is recessed downward in the top surface of the guide plate 51. The guide groove 511 penetrates the front and rear end faces of the guide plate 51. The guide groove 511 is used to receive the steel wire spool of the long row of spooled material 101 moving forward.

[0096] Multiple second mounting plates 52 correspond one-to-one with multiple second mounting slots 512; multiple second mounting plates 52 are spaced apart front to back and are vertically inserted into the corresponding second mounting slots 512; multiple second mounting plates 52 are divided into two groups distributed front to back, and the flow guide 511 is located between the two groups of second mounting plates 52; one end of two second rotating shafts 54 is inserted into the left side of the second mounting plate 52 facing the flow guide 511, and the other end of the second rotating shaft 54 ​​is rotatably mounted with a second shaping wheel 53; the two second rotating shafts 54 located on the same second mounting plate 52 are spaced apart vertically and aligned.

[0097] A gap is left between the two second shaping wheels 53 that are opposite each other; the gap arranged on the left side of the guide groove 511 forms a second shaping channel for shaping the steel strip coil located on the left side of the steel wire spool of the long row of braided material 101; the gap arranged on the right side of the guide groove 511 forms a third shaping channel for shaping the steel strip coil located on the right side of the steel wire spool of the long row of braided material 101.

[0098] like Figure 1 and Figure 5 As shown, the steel strip coils on both sides of the steel wire spool of the long row of hinges 101 are shaped by the second shaping channel located on the left side of the guide groove 511 and the third shaping channel located on the right side of the guide groove 511, which can improve the flatness and installation quality of the output long row of hinges.

[0099] Preferably, the gap width between the two sets of the second mounting plates 52 is adjustable.

[0100] like Figure 5 As shown, the production of long hinges of different widths can be adapted by adjusting the gap width between the two sets of second mounting plates 52.

[0104] The lower mold 212 is provided with a feed groove 2121, a support bar 2122 and a bobbin input groove 2123;

[0105] The feed groove 2121 is recessed in the top surface of the lower mold 212, and the feed groove 2121 extends along the front and rear and penetrates the front and rear end faces of the lower mold 212;

[0106] The support bar 2122 extends in a straight line in the front-back direction. The support bar 2122 is located on the central axis of the feed trough 2121. The bottom surface of the support bar 2122 is connected to the bottom surface of the feed trough 2121. The top surface of the support bar 2122 is a horizontal plane extending in the front-back direction.

[0107] The support bar 2122 divides the feed trough 2121 into two symmetrically distributed parts. The feed trough 2121 is wider at the back and narrower at the front. The left and right walls of the feed trough 2121 gradually move towards the left and right sides of the support bar 2122 from back to front.

[0108] The spool input groove 2123 is located near the rear end of the support bar 2122 and protrudes from the top surface of the support bar 2122; the spool input groove 2123 has a cylindrical slot 21231 inside; the slot 21231 extends through the spool input groove 2123 from front to back, and the central axis of the slot 21231 extends in a direction parallel to the top surface of the support bar 2122;

[0109] The upper mold 211 is provided with a curved groove 2111, which is recessed upward on the bottom surface of the upper mold 211. The curved groove 2111 is arranged vertically and vertically corresponding to the feed groove 2121. The curved groove 2111 is divided into a front half and a rear half. The curvature radius of the curved groove 2111 in the front half is smaller than that in the rear half.

[0110] like Figure 7-9As shown, during the process of hydraulic press 22 driving the rounding mold 21 to close and open the mold according to the rhythm, the steel wire passes through the slot 21231 from back to front and enters the lower mold 212. It moves forward above the top surface of the support bar 2122. The two serrated strips processed by the material cutting device 1 enter the feed groove 2121 from both sides of the support bar 2122. The serrated parts of the two serrated strips protrude upwards. The serrated parts of the two serrated strips are first punched by the curved groove 2111 of the rear half of the upper mold 211 to form a semi-circular arc and hook onto the steel wire above the support bar 2122, thus completing the semi-rounding action of the spool. Then, when entering the front half of the upper mold 211, the serrated parts of the two semi-circular serrated strips are punched by the curved groove 2111 of the front half to form a circular arc, so that the serrated parts of the two serrated strips are wrapped around the steel wire in a circular arc, thus completing the full rounding action of the spool.

[0111] In summary, such as Figure 1-9 In the embodiment of the present invention shown, the long-row hinge production line uses a pressing cylinder 811 to drive a pressing rod 812 to move up and down reciprocally according to a set rhythm. The rear edge of the bottom surface of the pressing rod 812 abuts against the front edge of the serration of one of the serrated strips in the long-row hinge material 101 to correct the gap between two serrated strips in the long-row hinge material 101, thereby correcting the misalignment, ensuring the quality of the produced long-row hinge, and avoiding manual rework.
