A valve plate tongue spring fixing groove is provided at the middle position of the left side of the top of the base box near the working groove. Although this technical solution can complete the micro bending of the valve plate tongue spring, the valve plate needs to be fixed every time it is bent, resulting in low work efficiency, high work intensity, and inability to achieve batch automated installation bending. Therefore, this application proposes a valve plate tongue spring micro bending device to solve the above problems. Summary of the Invention

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figure 1-11As shown, a valve plate tongue spring micro-bending device includes a top plate 1, a bottom plate 3 fixedly connected to the top plate 1 via a vertical rod 2, a turntable 4 movably connected to the top plate 1, a first motor 5 fixedly mounted on the top plate 1 to drive the turntable 4 to rotate, the first motor 5 being a servo motor, a placement groove 401 arranged in a circular pattern on the turntable 4 for placing valve plates, a bending forming plate 6 fixedly mounted on the upper part of the placement groove 401, a feeding structure 7 provided below the top plate 1, and the outlet of the feeding structure 7 corresponding to the placement groove 401, and a bending mechanism 8 also provided below the top plate 1, the bending mechanism 8 including a driving member 801, a pressing block 802 fixedly connected to the top end of the driving member 801, the driving member 801 sliding through the top plate 1.

[0030] like Figure 1 , 4 As shown in Figure 6, in this example, there are four placement slots 401. The feeding structure 7 and the bending mechanism 8 are respectively located below different placement slots 401. The feeding structure 7 and the bending mechanism 8 are arranged in the direction of rotation of the turntable 4. At the same time, there are six L-shaped blocks 9 on the outside of the turntable 4. The L-shaped blocks 9 are arranged in a circle and are fixedly connected to the top plate 1. The L-shaped blocks 9 are used to limit the circumference of the turntable 4, so that the turntable 4 is in close contact with the top plate 1, which makes it easy for the placement slots 401 to drive the valve plate to move.

[0031] like Figure 3 , 7 As shown, the bottom surface of the bending forming plate 6 is provided with a positioning protrusion 601. The bending forming plate 6 is fixedly connected to the turntable 4 by bolts. The positioning protrusion 601 is used to insert into the mounting hole of the valve plate to limit the valve plate and facilitate the movement of the valve plate. The installation position of the positioning protrusion 601 is determined according to the position of the mounting hole of the valve plate. At the same time, the size of the placement groove 401 is consistent with the outer size of the valve plate, so that the placement groove 401 can just place the valve plate. Furthermore, the distance between the bottom surface of the bending forming plate 6 and the bottom surface of the turntable 4 is consistent with the thickness of the valve plate, so that the bottom surface of the valve plate is flush with the bottom surface of the turntable 4 after the valve plate enters the placement groove 401.

[0032] like Figure 7 , 10 As shown in Figure 11, a forming groove 602 is provided on the bottom surface of the bending forming plate 6. The forming groove 602 is correspondingly provided with the tongue spring. The bottom surface of the forming groove 602 is bent, and the top surface of the pressing block 802 is matched with the forming groove 602. When the driving member 801 pushes the pressing block 802 upward, the pressing block 802 presses the tongue spring, causing the tongue spring to bend upward and fit against the bottom of the forming groove 602. The bending of the tongue spring.

[0033] like Figure 4 , 5As shown in Figures 8 and 9, the feeding structure 7 includes a holding cylinder 701, inside which a push plate 702 is provided. The push plate 702 is fixedly connected to the bottom of the holding cylinder 701 via a power device 703. The power device 703 is an electric push rod or an elastic structure, the elastic structure being a spring, preferably a spring in this example. A discharge groove 101 is provided on the top plate 1. The opening size of the discharge groove 101, the placement groove 401, and the holding cylinder 701 is the same. Under the push of the power device 703, the push plate 702 is pushed upward, thereby allowing the valve pieces stacked in the holding cylinder 701 to enter the placement groove 401 through the discharge groove 101. The turntable 4 rotates, and the placement groove 401 is offset from the discharge groove 101. The turntable 4 is used to press down and limit the valve pieces in the holding cylinder 701 until the next placement groove 401 is rotated to match the holding cylinder 701.

[0034] A U-shaped limiting strip 704 is fixedly connected to the bottom surface of the top plate 1. The longitudinal section of the limiting strip 704 is L-shaped. A protruding strip 705 that slides with the limiting strip 704 is provided on the top surface of the container 701. The protruding strip 705 slides within the limiting strip 704. The upper end of the container 701 is limited by the limiting strip 704. The bottom of the container 701 is fixedly connected to the bottom plate 3 by bolts, thus completing the fixation of the container 701.

[0035] like Figure 10 , 11 As shown, the bending mechanism 8 also includes two upright plates 803 fixedly connected to the top plate 1. The driving member 801 is located between the upright plates 803. Below the driving member 801, there is a shaft 804 movably connected to the upright plates 803. An eccentric structure 805 that contacts the bottom of the driving member 801 is fixedly connected to the shaft 804. In this example, the eccentric structure is an eccentric wheel. One end of the shaft 804 is connected to a second motor 806. The second motor 806 rotates to drive the shaft 804 to rotate, and the eccentric structure 805 reciprocates to drive the driving member 801 to move upward. Meanwhile, in order to enable the driving component 801 to reset downwards, a horizontal plate 807 is fixedly connected to the bottom of the driving component 801. A light rod 808 is slidably connected to both ends of the horizontal plate 807. The light rod 808 is fixedly connected to the top plate 1. A spring 809 is fixedly connected between the horizontal plate 807 and the top plate 1 on the outside of the light rod 808. After each bending and pressing, the driving component 801 moves downwards under the action of the spring 809, so that the driving component 801 resets.

[0036] like Figure 1 , 5As shown, an L-plate 10 is fixedly connected to the top plate 1, an electric push rod 11 is fixedly fixed to the L-plate 10, a discharge plate 12 is fixedly connected to the end of the electric push rod 11, and a discharge rod 13 is fixedly connected to the bottom surface of the discharge plate 12. There are four discharge rods 13 arranged in a matrix. A through hole 603 matching the discharge rod 13 is provided on the bending forming plate 6. A discharge groove 102 with a size not smaller than the placement groove 401 is provided below the discharge plate 12 on the top plate 1. The discharge plate 12 is located at the lower circumference of the bending mechanism 8. After the valve plate tongue spring is bent, the turntable 4 drives the valve plate to move below the discharge plate 12. The electric push rod 11 pushes the discharge plate 12 down, and the discharge rod 13 pushes the valve plate to fall from the discharge groove 102. At the same time, a collection box 14 is provided below the discharge groove 102 on the bottom plate 3. The collection box 14 is used to collect the valve plate.

[0037] Its working principle is as follows:

[0038] The valve piece to be bent is inserted into the holding cylinder 701, and then the holding cylinder 701 is fixed to the base plate 3. The first motor 5 is started, driving the turntable 4 to rotate. When the placement groove 401 on the turntable 4 rotates and the material discharge groove 101 is released, the valve piece in the holding cylinder 701 is pushed into the placement groove 401. The turntable 4 continues to rotate until it rotates above the bending mechanism 8. The second motor 806 drives the shaft 804 to rotate, and the eccentric structure 805 drives the driving component 801 to move upward. The pressing block 802 presses down... The valve plate spring is pressed against the bottom surface of the placement groove 401 to bend it. After bending, the turntable 4 continues to rotate until the valve plate rotates to the unloading groove 102. The unloading plate 12 pushes the valve plate out of the placement groove 401 and drops it into the collection box 14 for collection. The whole process is continuously cycled, with loading, bending and unloading carried out simultaneously. The continuous bending of the valve plate spring realizes the batch automated installation and bending of the valve plate spring, which greatly improves bending efficiency and reduces the labor intensity of workers.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above description is illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
