[0017] The present invention will be further described in conjunction with the following embodiments.

[0018] Depend on Figures 1 to 11 As can be seen, the horizontal spring machine described in this embodiment includes a frame 1; the frame 1 is provided with a feeding tray 11; a bottom column 2 is provided in the middle of the feeding tray 11; a rotating seat 3 is provided at the top of the bottom column 2; a rotating table 31 is fixedly connected to the top of the rotating seat 3; a machining clearance hole 32 is provided through the middle of the rotating table 31; a linear drive component 21 is provided in the bottom column 2; a mandrel 4 is provided at the output end of the linear drive component 21; the mandrel 4 moves up and down along the height direction and passes through the machining clearance hole 32; wherein the linear drive component 21 can be an electric actuator, a cylinder, or a hydraulic cylinder, etc. The rotary table 31 is provided with a final cutter 33, a shaping roller 35 and a feeding assembly 36 on the outer periphery of the machining clearance hole 32. The top of the mandrel 4 is provided with a threading groove 41; the top of the threading groove 41 is provided with a pressing block 42 that can be raised and lowered; a pressing spring 43 is provided between the top of the pressing block 42 and the top of the mandrel 4; the pressing spring 43 is used to drive the pressing block 42 to press the spring wire end into the threading groove 41. The frame 1 has a top seat 6 on top of the rotary table 31; the top seat 6 is equipped with a first cutter 72.

[0019] Specifically, in the horizontal spring machine described in this embodiment, the spring wire material is first placed on the feeding tray 11 of the frame 1, and the wire end is fed into the feeding assembly 36. The linear drive 21 drives the mandrel 4 to vertically adjust its height along the processing clearance hole 32 so that the wire groove 41 at the top of the mandrel 4 is aligned with the wire outlet position of the feeding assembly 36. Then, the wire end is inserted into the wire groove 41, and the spring 43 releases its elastic force to drive the pressing block 42 to feed downward, thereby firmly pressing and limiting the spring wire end in the wire groove 41, completing the wire end locking and fixing.

[0020] After the spring wire end is fixed, the rotating seat 3 drives the rotating table 31 to rotate circumferentially around the axis of the bottom column 2. The end cutter 33 and the shaping roller 35 on the rotating table 31 revolve synchronously with the rotating table 31. At the same time, the linear drive 21 drives the mandrel 4 to feed upward at a uniform speed. Under the combined action of the extrusion and shaping by the shaping roller 35 and the lifting and traction by the mandrel 4, the wire is continuously wound along the outer wall of the mandrel 4 to form a spiral spring body. When the winding length of the spring body reaches the preset value, the end cutter 33 feeds towards the mandrel 4 to cut off the end wire of the spring body. The mandrel 4 continues to drive the formed spring to move upward until the spring wire end is aligned with the first cutter 72 of the top seat 6. The first cutter 72 feeds and cuts off the connection between the spring wire end and the spring body, completing the forming process of a single spring.

[0021] This embodiment integrates the feeding tray 11, rotary table 31, shaping roller 35, first cutter 72, and last cutter 33 into a horizontal, unified layout. This eliminates the need for the separate tensioning and straightening structure required in vertical spring machines, effectively reducing the overall footprint of the equipment and improving the utilization rate of factory space. At the same time, relying on the elastic clamping structure formed by the liftable mandrel 4, the clamping block 42, and the clamping spring 43, the spring wire ends are locked. The rotary table 31 drives the shaping roller 35 to complete the spiral winding of the spring, and the first cutter 72 and the last cutter 33 complete the cutting of both ends of the spring in stages. This effectively overcomes the problem of poor material discharge caused by the weight of the spring itself in the horizontal layout, and can stably achieve continuous automated mass production of long springs, while ensuring the forming accuracy and dimensional consistency of the finished springs.

[0022] In this embodiment, a horizontal spring machine is provided, wherein the mandrel 4 has a lifting groove 44 in the middle; the feeding assembly 36 has a guide tube 37; the rotary table 31 has a feeding push rod 52 that cooperates with the lifting groove 44 on the outer periphery of the machining clearance hole 32; the rotary table 31 has a feeding drive component 51; the feeding drive component 51 is used to drive the feeding push rod 52 to approach and move away from the lifting groove 44; the top of the lifting groove 44 has a lifting inclined surface 45; the top of the feeding push rod 52 has a feeding inclined surface 53 that cooperates with the lifting inclined surface 45; wherein the feeding drive component 51 can be an electric push rod, a cylinder, or a hydraulic cylinder, etc. Specifically, the spring wire is conveyed along the guide tube 37 to the end to await loading. The linear drive 21 drives the mandrel 4 to adjust its height, so that the lifting groove 44 in the middle of the mandrel 4 is completely aligned with the height of the loading push rod 52. The loading drive 51 drives the loading push rod 52 to feed horizontally towards the lifting groove 44. The loading ramp 53 at the front end of the loading push rod 52 contacts and adheres to the lifting ramp 45 at the top of the lifting groove 44. As the loading push rod 52 continues to advance, the horizontal thrust of the ramp is converted into a vertical thrust. The force is applied to lift the clamping block 42 upwards, overcoming the elastic force of the clamping spring 43 and raising the clamping block 42, thus fully opening the entrance of the wire threading groove 41. At this time, the wire passes out from the guide tube 37 and horizontally enters the open wire threading groove 41. The feeding drive unit 51 then drives the feeding push rod 52 to exit the lifting groove 44. After the clamping spring 43 loses external force support, it resets and drives the clamping block 42 downwards to press firmly, firmly pressing the inserted spring wire end into the wire threading groove 41, thus completing the fully automatic feeding and locking wire action.

[0023] This embodiment describes a horizontal spring machine, in which the rotary table 31 is equipped with a final cutting drive 34. The final cutting drive 34 is used to drive the final cutting blade 33 to approach and move away from the mandrel 4. The final cutting drive 34 can be an electric actuator, a cylinder, or a hydraulic cylinder, etc. During the spring winding process, the final cutting blade 33 and the final cutting drive 34 revolve synchronously with the rotary table 31, always maintaining a fixed relative position with the forming roller 35, and following the rotary table 31 to rotate circumferentially around the mandrel 4. When the height of the mandrel 4 reaches the preset processing length corresponding to the spring length, the rotary table 31 stops rotating, and the final cutting drive 34 immediately outputs a linear driving force to push the final cutting blade 33 to quickly feed towards the mandrel 4, with the blade adhering to the outer wall of the mandrel 4 to cut the end of the wound wire. After the cutting is completed, the final cutting drive 34 drives the final cutting blade 33 to quickly reset and avoid structural interference when the mandrel 4 is lifted or the rotary table 31 rotates.

[0024] This embodiment describes a horizontal spring machine, in which the top seat 6 is provided with a feeding drive 73; the output end of the feeding drive 73 is provided with a feeding plate 7; the feeding drive 73 is used to drive the feeding plate 7 to perform reciprocating linear motion; the middle part of the feeding plate 7 is provided with a processing clearance channel 71; the first cutter 72 is provided on one side of the processing clearance channel 71; wherein the feeding drive 73 can be an electric push rod, a cylinder, or a hydraulic cylinder, etc.; specifically, when the mandrel 4 drives the formed spring to feed upward, it moves from the middle part of the feeding plate 7. The processing clearance channel 71 passes through, and the spring wire end rises with the mandrel 4 to a height level with the first cutter 72; the unloading drive 73 drives the unloading plate 7 to move horizontally in the direction of the mandrel 4. The first cutter 72, located on one side of the processing clearance channel 71, feeds synchronously with the unloading plate 7, and the blade is aligned with the connection between the spring wire end and the spring body to complete the cutting; after the cutting is completed, the unloading drive 73 drives the unloading plate 7 to move in the opposite direction to reset, and the first cutter 72 then moves back to avoid, making way for the upward discharge of the subsequent finished spring products.

[0025] In this embodiment, a horizontal spring machine is described, wherein the threading groove 41 is arranged to pass through the mandrel 4 in the radial direction; the unloading plate 7 is provided with an unloading block 8 on the other side of the processing clearance channel 71; the unloading block 8 is provided with an unloading push rod 81 that cooperates with the lifting groove 44; the top of the lifting groove 44 is provided with a lifting inclined surface 45; the top of the unloading push rod 81 is provided with an unloading inclined surface 82 that cooperates with the lifting inclined surface 45.

[0026] Specifically, after the first cutter 72 completes the wire end cutting, the feeding drive 73 continues to drive the feeding plate 7 to move in the opposite direction. The feeding block 8 and the feeding push rod 81, located on the other side of the processing clearance channel 71, move towards the spindle 4 in sync. The feeding inclined surface 82 at the front end of the feeding push rod 81 contacts the lifting inclined surface 45 at the top of the lifting groove 44. As the feeding push rod 81 continues to advance, the vertical component force generated by the inclined surface will once again push the clamping block 42 upward, overcoming the elastic force of the clamping spring 43 to lift the clamping block 42, so that the cut spring wire end is lifted in sync with the clamping block 42, forming a misalignment in height with the spring body below. At this time, the two ends of the radially penetrating wire groove 41 are completely open, providing horizontal operating space for the subsequent wire end ejection action.

[0027] In this embodiment of the horizontal spring machine, the bottom of the pressing block 42 is provided with a permanent magnet 46; the feeding block 8 is provided with a pushing rod at the bottom of the feeding push rod 81; after the permanent magnet 46 attracts the spring wire end, the pushing rod passes into the threading groove 41 and pushes the spring wire end attracted to the permanent magnet 46 out of the threading groove 41.

[0028] Specifically, during the process of the feeding push rod 81 lifting the clamping block 42 through the inclined surface, the permanent magnet 46 at the bottom of the clamping block 42 attracts the metal spring wire end to the bottom surface of the clamping block 42, so that the wire end is raised synchronously with the clamping block 42 and keeps its position fixed, forming a clear height misalignment with the spring body below; as the feeding plate 7 continues to feed, the feeding push rod synchronously and horizontally enters the radially penetrating wire groove 41, and the end of the push rod is aligned with the spring wire end attracted to the permanent magnet 46. The horizontal pushing force overcomes the attraction force of the permanent magnet 46 and pushes the spring wire end horizontally out from the other side of the wire groove 41, so that the wire end is completely separated from the mandrel 4; after the feeding is completed, the feeding plate 7 drives the feeding push rod and the feeding push rod 81 to retract synchronously, and the clamping spring 43 resets and drives the clamping block 42 to fall.

[0029] In this embodiment of the horizontal spring machine, the top seat 6 is provided with a feeding track 61 at the bottom of the processing clearance channel 71. After the spring wire end pushed out of the wire groove 41 by the push rod loses its support, it falls vertically under the action of gravity and falls exactly into the feeding track 61 set at the bottom of the processing clearance channel 71 on the top seat 6; the wire end slides down the guide slope or guide groove of the feeding track 61 in a direction and is uniformly transported to the waste collection position on the side of the equipment, and will not be scattered inside the processing station.

[0030] In this embodiment, a horizontal spring machine is provided with a clamping seat 62 at the bottom of the top seat 6; the clamping seat 62 is located on the top of the rotary table 31; a first clamping wheel 63 is rotatably provided on one side of the clamping seat 62; a second clamping wheel 64 is rotatably provided on the other side of the clamping seat 62; a clamping channel is formed between the first clamping wheel 63 and the second clamping wheel 64; the machining clearance hole 32, the clamping channel, and the machining clearance channel 71 are arranged sequentially along the height direction. Specifically, when the mandrel 4 drives the wound spring upward, the spring body first enters the clamping channel formed by the first clamping wheel 63 and the second clamping wheel 64 on the clamping seat 62. The two clamping wheels clamp the outer wall of the spring from both sides, and rely on rolling friction to form a radial preload on the spring. When the final cutter 33 cuts the end of the spring and the first cutter 72 cuts the end of the spring wire, the clamping channel always clamps the spring body, keeping the spring in a vertical tension state and preventing positional displacement due to cutting impact. When the mandrel 4 retracts downward, the friction of the clamping wheels limits the spring body in the clamping channel, allowing the mandrel 4 to be smoothly pulled out from the inner coil of the spring. The spring temporarily stays in the clamping channel waiting for discharge. The processing clearance hole 32, the clamping channel, and the processing clearance channel 71 are arranged coaxially in sequence to ensure coaxial guidance throughout the spring lifting process.

[0031] In this embodiment, a horizontal spring machine is provided with swing blocks 47 movably on both sides of the top of the mandrel 4; the swing blocks 47 are located on the top of the pressing block 42; the inner side of the swing blocks 47 is hinged to the top of the mandrel 4; the outer side of the swing blocks 47 protrudes from the outer wall of the mandrel 4 when placed horizontally.

[0032] Specifically, after a single spring is cut, the linear drive 21 drives the spindle 4 to retract downwards. When the swing block 47 at the top of the spindle 4 contacts the bottom of the inner ring of the spring, it is pushed upwards by the end face of the spring. The swing block 47 swings inwards and upwards around the hinge point, and the whole thing is closed within the top range of the spindle 4. The spindle 4 is then smoothly pulled downwards from the inner ring of the spring. When the swing block 47 is completely separated from the inner ring of the spring, it swings downwards and outwards around the hinge point under its own gravity to reset, returning to a horizontal position. The outer side protrudes out of the outer wall of the spindle 4 again. In the next round of processing, the spindle 4 feeds upwards again. After resetting, the upper end face of the protruding swing block 47 supports the bottom of the previous spring that is still in the clamping channel, pushing the entire spring upwards and pushing the finished spring out of the clamping channel to above the processing clearance channel 71.

[0033] This embodiment describes a horizontal spring machine, which further includes a loading robot movably positioned at the top of the processing clearance channel 71; however, the loading robot is not shown in the figure. After the swing block 47 rises with the mandrel 4 and completely pushes the spring body out from the top of the processing clearance channel 71, the loading robot movably positioned at the top of the processing clearance channel 71 moves to directly above the spring, and the grippers close to grab the upper part of the spring; then the robot moves the finished spring horizontally away from the processing station, placing the spring in the finished product storage area or on the conveyor line, completing the fully automatic unloading of a single spring; after unloading is completed, the robot returns to its initial position, waiting for the next spring to be pushed out before repeating the gripping action.

[0034] Specifically, the complete workflow of the horizontal spring machine described in this embodiment is as follows: First, the spring wire material coil is placed on the feed tray 11 of the frame 1. The wire end is led out and passed through the guide tube 37 of the feeding assembly 36, waiting for feeding. The linear drive 21 drives the mandrel 4 to rise and fall along the machining clearance hole 32 to adjust its height, so that the lifting groove 44 in the middle of the mandrel 4 is aligned with the feeding push rod 52. The feeding drive 51 drives the feeding push rod 52 to feed into the lifting groove 44. Through the cooperation of the feeding inclined surface 53 and the lifting inclined surface 45, the clamping block 42 is pushed upward, overcoming the elastic force of the clamping spring 43 and lifting, so that the wire threading groove 41 is fully opened. The wire end then passes into the wire threading groove 41. Afterward, the feeding push rod 52 exits the lifting groove 44, the clamping spring 43 resets and drives the clamping block 42 to feed downward. The spring wire end is firmly pressed into the threading groove 41 to complete the wire locking and fixing; then the rotating seat 3 drives the rotating table 31 to rotate circumferentially, so that the shaping roller 35 and the final cutter 33 revolve around the mandrel 4 synchronously with the rotating table 31. At the same time, the linear drive 21 drives the mandrel 4 to feed upward at a uniform speed. Under the extrusion and shaping action of the shaping roller 35, the wire is continuously wound along the outer wall of the mandrel 4 to form a spiral spring body. When the spring winding length reaches the preset processing value, the final cutter drive 34 drives the final cutter 33 to feed towards the mandrel 4 and cut off the end of the spring body; the mandrel 4 continues to drive the spring body to move upward, and the spring body enters the clamping channel formed by the first clamping wheel 63 and the second clamping wheel 64 on the clamping seat 62, and is then... The double clamping wheels form a radial preload limit on the spring until the top of the mandrel 4 rises to the processing clearance channel 71 of the unloading plate 7, and the spring wire end is aligned with the first cutter 72. The unloading drive 73 drives the unloading plate 7 to feed horizontally towards the mandrel 4. The first cutter 72, located on one side of the processing clearance channel 71, approaches and cuts the connection between the spring wire end and the spring body. The unloading plate 7 moves in the opposite direction, causing the unloading push rod 81 to enter the lifting groove 44. Through the cooperation of the unloading inclined surface 82 and the lifting inclined surface 45, the clamping block 42 is lifted again. The permanent magnet 46 at the bottom of the clamping block 42 attracts the cut spring wire end and lifts it synchronously, so that the wire end and the spring body below are misaligned. At the same time, the push rod penetrates the radial through-hole. Inside the threading groove 41, the spring wire end adsorbed on the permanent magnet 46 is pushed horizontally from the other side of the threading groove 41. The wire end falls to the feeding track 61 and is discharged and collected in a directional manner. After the cutting and feeding are completed, the feeding plate 7 drives the first cutter 72, the feeding push rod 81 and the feeding push rod to reset and avoid. The linear drive 21 drives the spindle 4 to retract downward. The swing block 47 at the top of the spindle 4 is blocked by the end face of the inner ring of the spring and swings inward and upward around the hinge point to retract, so that the spindle 4 can be smoothly pulled out from the inner ring of the spring. The spring body is limited by the friction of the clamping channel and kept in the original position. When the swing block 47 is completely separated from the inner ring of the spring, it swings outward and downward to reset under its own gravity, and the outer side protrudes out of the outer wall of the spindle 4 again.During the next round of spring winding, the continuously rising mandrel 4, through the repositioned and protruding swing block 47, lifts the bottom of the previous finished spring, pushing the spring upward from the clamping channel to above the processing clearance channel 71. Finally, the unloading robot, movably positioned at the top of the processing clearance channel 71, grips and transfers the spring, completing the fully automated processing and unloading of a single spring.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
