The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] The present invention relates to a computer numerical control spring machine. For example, the computer numerical control spring machine includes a wire feeding mechanism, a spring winding main machine, a numerical control platform and a material receiving mechanism, wherein the wire feeding mechanism is arranged on one side of the spring winding main machine. For example, the numerical control platform is arranged on the other side of the spring winding main machine and is electrically connected to the spring winding main machine, and the material receiving mechanism is arranged at the bottom of the spring winding main machine for collecting the fallen springs. For example, the material receiving mechanism includes a guide seat, a baffle plate and a collecting seat, wherein the guide seat is arranged at the bottom of the spring winding main machine, a tapered groove is arranged on the guide seat, and an inclined guiding surface is formed on the side wall of the tapered groove. For example, the inner cavity size of the tapered groove gradually decreases in the direction toward the ground, the baffle plate is baffled on one side of the tapered groove, and the baffle plate is arranged opposite to the inclined guiding surface of the guide seat. For example, the distance between the baffle plate and the inclined guiding surface gradually decreases in the direction toward the ground, a guide tube is arranged at the bottom of the tapered groove, and the collecting seat is located below the guide seat. For example, a plurality of collecting holes are provided on the collecting seat, and the plurality of collecting holes are used to align with the guide tube in sequence.

[0021] See also Figures 1 to 3A computer numerical control spring machine 100 includes a wire feeding mechanism, a spring winding main machine 20, a numerical control platform 30 and a material receiving mechanism 40, wherein the wire feeding mechanism is arranged on one side of the spring winding main machine 20, the numerical control platform 30 is arranged on the other side of the spring winding main machine 20, and is electrically connected to the spring winding main machine 20, the material receiving mechanism 40 is arranged at the bottom of the spring winding main machine 20, and is used to collect the fallen spring 200, the material receiving mechanism 40 includes a guide seat 41, a baffle plate 42 and a collecting seat 45, the guide seat 41 is arranged at the bottom of the spring winding main machine 20, and a tapered groove 411 is arranged on the guide seat 41, The side wall of the tapered groove 411 is formed with an inclined guide surface 413, and the inner cavity size of the tapered groove 411 gradually decreases in the direction toward the ground. The baffle plate 42 is blocked on one side of the tapered groove 411, and the baffle plate 42 is arranged opposite to the inclined guide surface 413 of the guide seat 41. The distance between the baffle plate 42 and the inclined guide surface 413 gradually decreases in the direction toward the ground. A guide tube 415 is provided at the bottom of the tapered groove 411, and the collecting seat 45 is located below the guide seat 41. A plurality of collecting holes 451 are opened on the collecting seat 45, and the plurality of collecting holes 451 are used to align the guide tube 415 in sequence.

[0022] When the CNC spring machine 100 is in use, the collecting seat 45 moves so that one of the collecting holes 451 is aligned with the guide tube 415, and the spring 200 made on the spring winding main machine 20 falls into the tapered groove 411 of the guide seat 41 and descends under gravity. The tapered groove 411 and the retaining plate 42 guide the spring 200 to turn to the axial downward direction, then enter the guide tube 415, and finally vertically insert into the collecting hole 451 of the collecting seat 45. Thereafter, the collecting seat 45 moves forward so that another collecting hole 451 is aligned with the guide tube 415, so as to prepare to collect the spring 200 again. Through the cooperation of the tapered groove 411 and the retaining plate 42, the direction of the spring 200 can be relatively straightened, and then the spring 200 can be arranged on the collecting seat 45 more conveniently, thereby improving the collection efficiency and production efficiency of the spring 200.

[0023] For example, in order to facilitate guiding the spring 200, a vertical surface 414 is provided at the bottom of the inclined guide surface 413, and the vertical surface 414 is smoothly connected to the inclined guide surface 413 through an arc surface. Two guide side walls 416 are convexly provided on opposite sides of the inclined guide surface 413, and an introduction frame 47 is convexly provided on the guide seat 41, wherein an inclined baffle 417 is rotatably provided on one of the guide side walls 416, and the inclined baffle 417 extends to the inclined guide surface 413. The introduction frame 47 includes a main board 471 and clamping plates 473 convexly provided on opposite sides of the main board 471, and the two clamping plates 473 are respectively connected to the two guide side walls 416. A clamping gap 4135 is formed between the two clamping plates 473, and the width of the clamping gap 4135 is smaller than the diameter of the spring 200. The clamping gap 4135 is located on a side away from the main board 471. By providing the introduction frame 47, the spring 200 can be collected by the introduction frame 47. The rotatably arranged inclined baffle 417 can block one end of the spring 200 so that the spring 200 does not fall sideways, and guides one end of the spring 200 to move downward first.

[0024] For example, in order to facilitate the final adjustment of the spring 200, the bottom of the baffle plate 42 is fixed to the top of the guide tube 415. A vertical guide surface 4715 is formed on the surface of the main board 471, and the top of the inclined guide surface 413 is connected to the bottom of the vertical guide surface 4715, and the angle between the inclined guide surface 413 and the vertical guide surface 4715 is 130-150 degrees. The distance between the two guide side walls 416 gradually decreases in the direction toward the ground, and the inner diameter of the guide tube 415 is 1.1-1.3 times the outer diameter of the spring 200. An elastic absorption layer is provided on the surface of the inclined guide surface 413, and a lever gap 4155 is provided on the guide tube 415, and the lever gap 4155 extends along the length direction of the guide tube 415. An elastic absorption layer is provided on the surface of the inclined guide surface 413, so after the spring 200 falls along the vertical guide surface 4715, it hits the elastic absorption layer to absorb its elastic force to prevent the spring 200 from bouncing too far, and the baffle plate 42 can block it back. After the elastic collision, the spring 200 hits the inclined baffle plate 417 again, so that one end of it faces downward and its direction is initially corrected. Thereafter, the spring 200 falls downward along the inclined baffle plate 417 and falls into the guide tube 415, and finally its direction is corrected.

[0025] For example, it is particularly important that, in order to facilitate the movement of the collecting seat 45, the material receiving mechanism 40 further includes a conveying frame 46 and a pushing cylinder 48, the conveying frame 46 is formed with a conveying channel 461, the bottom surface of the conveying channel 461 is provided with a plurality of steel rods 4615, the collecting seat 45 is slidably arranged in the conveying channel 461 and supported on the plurality of steel rods 4615, the pushing cylinder 48 is arranged at one end of the conveying frame 46 and abuts against the collecting seat 45, and is used to push the collecting seat 45 to move intermittently. For example, in order to facilitate slowing down the descending speed of the spring 200, so as to adjust the angle of the spring 200, a closed electric control coil is arranged in the guide tube 415, and the electric control coil is electrically connected to the first power supply 4158, and the first power supply 4158 is used to control the on and off of the electric control coil to generate a magnetic field. Since the spring 200 is made of steel, after the spring 200 quickly enters the guide tube 415, the first power source 4158 generates a magnetic field through the electric control coil to generate or disappear the current to absorb the spring 200, thereby slowing down the descending speed of the spring 200. The existence of the lever gap 4155 on the guide tube 415 causes the magnetic field to be weaker on the side adjacent to the lever gap 4155, so that the spring 200 is absorbed on the side of the guide tube 415 away from the lever gap 4155. For example, the guide tube 415 is coaxially arranged with the collection hole 451, and the central axis of the collection hole 451 forms an angle of 85-88 with respect to the bottom surface of the collection seat 45. Through the absorption of the spring 200 by the magnetic field, the spring 200 can move downward at a lower speed along the side of the guide tube 415 away from the lever gap 4155, and finally smoothly enter the inclined collection hole 451. The spring 200 will not pop out of the collecting hole 451 or hit the bottom of the collecting hole 451 due to excessive speed. For example, the existence of the lever gap 4155 also facilitates the spring 200 to be inserted into the lever gap 4155 to poke out the spring 200 when the spring 200 is blocked in the guide tube 415.

[0026] For example, in order to prevent the subsequent spring 200 from blocking the guide tube 415 after the spring 200 falls onto the inclined guide surface 413, one end of the inclined guide surface 413 is connected to one of the guide side walls 416, and a resisting spring is provided in the middle of the guide side wall 416. The end of the resisting spring away from the inclined guide surface 413 is connected to the guide side wall 416, and the resisting spring resists the inclined baffle 417 at an inclined angle. In order to close the tapered groove 411, a telescopic capsule is provided in the middle of the resisting spring, and the telescopic capsule extends along the central axis of the resisting spring. A disc magnet is provided at the end of the telescopic capsule, and the disc magnet is adsorbed on the inclined baffle 417 to stretch the telescopic capsule. An actuating coil is wound around the far end of the resisting spring adjacent to the guide side wall 416, and the actuating coil is electrically connected to the second power supply. The second power source is used to energize the actuating coil so that the actuating coil generates a magnetic field, forcing the disk magnet to pull up the telescopic capsule and away from the actuating coil, thereby pushing the inclined baffle 417 to rotate to stop the tapered groove 411, temporarily blocking the descent of the spring 200. After that, the second power source stops energizing, allowing the spring 200 to descend to the inclined guide surface 413 under gravity, and the blocking effect of the inclined baffle 417 is used to delay the time for the spring 200 to arrive in the guide tube 415, thereby avoiding blockage caused by two springs 200 entering the guide tube 415 at the same time. For example, the actuating coil extends along the spiral line of the resisting spring, and the density of the number of turns is greater than the number of turns of the resisting spring.
