DETAILED DESCRIPTION

[0029] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figure 1-Figure 8 The present invention provides a technical solution: a wide flat spring piece forming device, the forming device comprising: a base 1.

[0031] Specifically, a fixed column 4 is arranged above the base 1, a horizontally arranged pad 41 is fixed at the bottom of the fixed column 4, and an avoidance groove 411 is opened on the surface of the pad 41, a groove is arranged on the upper surface of the base 1, and a gap is left between the bottom of the groove and the pad 41, the edge of the pad 41 is fixedly connected to the edge of the upper surface of the base 1, the fixed column 4 and the pad 41 are both kept in fixed position, a spring workpiece 3 transported by the conveyor belt 2 is arranged on one side of the fixed column 4, and the conveyor belt 2 is installed on the base 1, such as Figure 1 and Figure 2 As shown, when the conveyor belt 2 is working, it drives the spring piece workpiece 3 to move on the upper surface of the base 1, and finally conveys the spring piece workpiece 3 to between the pad 41 and the base 1. A punching head 12 for punching the spring piece workpiece 3 is arranged above the avoidance groove 411. The punching head 12 can be used to punch the end of the spring piece workpiece 3 when it moves up and down. The avoidance groove 411 is provided to prevent the punching head 12 from being blocked by the pad 41.

[0032] Secondly, a gear ring 7 is rotatably installed on the outer side of one end of the fixed column 4, and the gear ring 7 is concentric with the fixed column 4. A bending roller 5 is arranged below the fixed column 4, and the bending roller 5 is rotatably connected to the inner wall of the gear ring 7. A gap is left between the bending roller 5 and the fixed column 4, and the size of the gap is consistent with the thickness of the spring piece workpiece 3. The bending roller 5 is accommodated in the interior of the base 1, and a cavity for the movement of the bending roller 5 is opened in the interior of the base 1. When the gear ring 7 rotates, the bending roller 5 can move accordingly and rotate around the fixed column 4. Since the fixed column 4 and the bending roller 5 are respectively located on the upper and lower sides of the spring piece workpiece 3, the bending roller 5 can bend the spring piece workpiece 3 when it rotates around the fixed column 4 until the bending roller 5 moves to the position closest to the avoidance groove 411, and the spring piece workpiece 3 can be bent to a desired shape (such as Figure 2 and Figure 3As shown), at this time, the two ends of the spring sheet workpiece 3 correspond to each other, and the two ends of the spring sheet workpiece 3 are respectively located on the upper and lower sides of the pad 41, and then the punching head 12 punches the spring sheet workpiece 3, so that two completely corresponding holes can be formed on the spring sheet workpiece 3 at one time, and then the punching head 12 is withdrawn and the bending roller 5 is rotated in the reverse direction. The bending roller 5 no longer presses the spring sheet workpiece 3, and the spring sheet workpiece 3 can be slightly opened outward under the action of its own elasticity, so as to facilitate separation from the fixing column 4, as shown in FIG. Figure 2 As shown, a notch is provided on the side of the groove on the upper surface of the base 1 , and the position of the notch corresponds exactly to the fixing column 4 and the pad 41 , so that the spring piece workpiece 3 can move along the length direction of the fixing column 4 , thereby being separated from the fixing column 4 .

[0033] In order to install the gear ring 7, the present application also has a connecting frame 71 fixed on the inner side of the gear ring 7, and the connecting frame 71 is in a "Y" shape. The setting of the connecting frame 71 can be used to shape and reinforce the gear ring 7 to prevent the gear ring 7 from deforming itself, and the middle part and one end of the connecting frame 71 are respectively fixed with a sleeve 1 72 and a sleeve 2 73, one end of the fixed column 4 is fixed with a fixed shaft 42, and the fixed shaft 42 passes through the inner cavity of the sleeve 1 72 through the bearing, and one end of the bending roller 5 passes through the inner cavity of the sleeve 2 73 through the bearing. Figure 4 As shown, the sleeve 1 72 can only rotate outside the fixed shaft 42, so the gear ring 7 can only rotate around the fixed column 4. Since the bending roller 5 is rotatably connected to the sleeve 2 73, the bending roller 5 can rotate around the fixed column 4 (i.e., revolution) while rotating around the fixed column 4 and rotating around its own axis (i.e., rotation). Figure 1 As shown, when the bending roller 5 is in a position directly below the fixed column 4, the conveyor belt 2 conveys the spring piece workpiece 3, and one end of the spring piece workpiece 3 passes through the gap between the fixed column 4 and the bending roller 5. Since the spring piece workpiece 3 will gradually detach from the conveyor belt 2, the movement of the spring piece workpiece 3 will gradually lose power. Therefore, at this time, the bending roller 5 can continue to convey the spring piece workpiece 3 by rotating until the spring piece workpiece 3 is conveyed to the specified position. When the bending roller 5 revolves around the fixed column 4, the bending roller 5 can also roll on the surface of the spring piece workpiece 3. At this time, the sliding friction between the bending roller 5 and the spring piece workpiece 3 will not cause the position of the spring piece workpiece 3 to shift, thereby ensuring the stability of the position of the spring piece workpiece 3.

[0034] In order to ensure that the bending roller 5 can easily bend the spring sheet workpiece 3, the present application also has a protective cover 6 fixed on one side of the base 1. The protective cover 6 is a hollow structure and covers the outer side of the ring gear 7. The setting of the protective cover 6 is mainly used to protect the ring gear 7. A driving gear 74 is rotatably installed in the inner cavity of the protective cover 6, and the driving gear 74 is meshed with the ring gear 7 for transmission. A motor 741 is fixed on the surface of the protective cover 6 for driving the driving gear 74 to rotate. When the motor 741 is working, it drives the driving gear 74 to rotate, thereby driving the ring gear 7 to rotate. Since the driving gear 74 is meshed with the outer side of the ring gear 7 and the diameter of the driving gear 74 is smaller than the diameter of the ring gear 7, the connecting frame 71 between the sleeve 1 72 and the sleeve 2 73 can be regarded as a labor-saving lever. That is to say, the revolution of the bending roller 5 around the fixed column 4 has a large torque, thereby ensuring that the bending roller 5 can easily bend the spring sheet workpiece 3 when it revolves.

[0035] In order to drive the bending roller 5 to rotate, the present application also has a synchronous belt 8 provided in the inner cavity of the protective cover 6, and a driving pulley 81 and a driven pulley 82 are provided at both ends of the synchronous belt 8, a rotating shaft is provided through the middle of the driving pulley 81 through a bearing, and one end of the rotating shaft is fixedly connected to the fixed shaft 42, and the driven pulley 82 is fixed to one end of the bending roller 5, combined with Figure 4 and Figure 5 As shown, when the driving pulley 81 rotates, the driven pulley 82 can be driven to rotate synchronously through the transmission of the synchronous belt 8, thereby realizing the self-rotation of the bending roller 5.

[0036] In order to drive the driving pulley 81 to rotate, the present application also has a second motor 83 arranged on the outer side of the protective cover 6, and the second motor 83 is fixed on the stand, which penetrates the surface of the protective cover 6 and is fixedly connected to the sleeve 1 72. When the motor 83 is working, it is used to drive the driving pulley 81 to rotate, thereby driving the driven pulley 82 and the bending roller 5 to rotate. Figure 4 As shown, the stand mainly includes a circular plate and multiple columns. The circular plate is used to install the motor 83, and the columns are dispersedly fixed on the end face of the sleeve 72 to avoid interference with the synchronous belt 8. When the ring gear 7 rotates, the motor 83 and the stand will rotate synchronously. Therefore, a circular hole for the stand to rotate is opened on the surface of the protective cover 6 to avoid interference between the stand and the protective cover 6.

[0037] In order to push the spring piece workpiece 3 out from the upper surface of the base 1, the present application also has a discharge cylinder 9 fixed on the surface of the protective cover 6, the movable end of the discharge cylinder 9 movably penetrates the protective cover 6 and extends to the inner cavity of the protective cover 6, and a protrusion is fixed to the movable end of the discharge cylinder 9, which is opposite to the edge of the spring piece workpiece 3 and is offset from the bending roller 5. The discharge cylinder 9 itself can be extended and retracted, and the protrusion can be used to push the spring piece workpiece 3 so as to push the spring piece workpiece 3 out from the upper surface of the base 1.

[0038] In order to, the present application also has a limiting ring 52 fixed on the outer side of one end of the bending roller 5, and the limiting ring 52 is attached to the surface of the fixed column 4 to prevent the spring piece workpiece 3 between the fixed column 4 and the bending roller 5 from deviating along the length direction of the fixed column 4. A plurality of flexible pads 51 distributed at equal intervals are bonded to the surface of the bending roller 5, and a plurality of sleeve rings 43 distributed at equal intervals are arranged on the surface of the fixed column 4. Since the fixed column 4 itself cannot rotate, but the sleeve ring 43 can rotate around the fixed column 4, the bending roller 5 rotates through the space between the flexible pad 51 and the spring piece workpiece 3. The friction force can convey the spring piece workpiece 3, and the friction force between the spring piece workpiece 3 and the ring 43 can drive the ring 43 to rotate, thereby avoiding excessive friction between the fixed column 4 and the spring piece workpiece 3 and affecting the normal conveying of the spring piece workpiece 3; in addition, it should be noted that although the conveying of the spring piece workpiece 3 can be avoided from being hindered by increasing the gap between the fixed column 4 and the bending roller 5, this will affect the bending effect of the bending roller 5 on the spring piece workpiece 3, and therefore the gap between the fixed column 4 and the bending roller 5 needs to be exactly the same as the thickness of the spring piece workpiece 3.

[0039] In order to prevent the spring piece workpiece 3 from shifting along the length direction of the fixed column 4, the present application also has an annular groove on the surface of the fixed column 4 for the ring 43 to rotate, a rubber pad 431 is bonded to the surface of the ring 43, and the inner wall of the ring 43 is movably inlaid with multiple rolling elements 432 distributed in a ring array. The rubber pad 431 and the flexible pad 51 both have a certain elastic deformation ability, which can realize the compression of the spring piece workpiece 3. On the one hand, it ensures that the spring piece workpiece 3 is transported when the bending roller 5 rotates, and on the other hand, it avoids the position displacement of the spring piece workpiece 3 in the length direction of the fixed column 4.

[0040] In order to avoid the collision between the spring piece workpiece 3 and the punching head 12 during bending, the present application also has a punching groove corresponding to the avoidance groove 411 on the upper surface of the base 1, and a chip removal groove 11 is provided at the bottom of the punching groove. The punching groove is provided for the punching head 12 to be inserted downward, and the chip removal groove 11 is provided for discharging the debris and waste generated after punching. A slide seat 13 is horizontally slidably installed at one end of the base 1, and the punching head 12 is installed on the slide seat 13 and driven up and down by a cylinder. When the slide seat 13 slides, it can drive the punching head 12 to move horizontally, thereby avoiding interference between the spring piece workpiece 3 and the punching head 12 during the bending process.

[0041] In order to avoid deformation of the punching slot on the base 1, the slide 13 of the present application is driven by another cylinder to slide close to the base 1. A boss is fixed on one side of the slide 13 close to the base 1. The boss is movably inserted into the inner cavity of the chip groove 11. The thickness of the boss is consistent with the height of the chip groove 11. Figure 1 and Figure 2As shown, when the slide 13 slides close to the base 1, the boss can be inserted into the inner cavity of the chip groove 11. At this time, the boss can support the hollow area inside the chip groove 11, thereby preventing the punching head 12 from generating a large impact force when punching the spring piece workpiece 3, causing the upper surface of the base 1 to be concave and deformed.

[0042] 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 appended claims and their equivalents.
