[0030] Embodiment one, please refer to Figures 1-8 The utility model provides a technical scheme: a wide flat spring piece forming equipment, the forming equipment includes: base 1.

[0031] Specifically, the fixed column 4 is arranged above the base 1, the fixed column 4 bottom is fixed with the horizontally arranged backing plate 41, and the backing plate 41 surface is provided with the avoiding groove 411, the upper surface of the base 1 is provided with the recess, and the gap is left between the groove bottom of the recess and the backing plate 41, the edge of the backing plate 41 is fixedly connected with the edge of the upper surface of the base 1, the fixed column 4 and the backing plate 41 are kept fixed in position, and the fixed column 4 is provided with the spring piece workpiece 3 conveyed by the conveying belt 2 on one side, and the conveying belt 2 is installed on the base 1, as shown in Figure 1 And Figure 2 When the conveying belt 2 works, the spring piece workpiece 3 is driven to move on the upper surface of the base 1, and finally the spring piece workpiece 3 is conveyed between the backing plate 41 and the base 1, the punching head 12 for punching the spring piece workpiece 3 is arranged above the avoiding groove 411, and the punching head 12 can be used for punching the end of the spring piece workpiece 3 when moving up and down, and the avoiding groove 411 is arranged to avoid the blocking of the punching head 12 by the backing plate 41;

[0032] Secondly, the gear ring 7 is rotatably installed on one end of the fixed column 4, the gear ring 7 is concentric with the fixed column 4, the bending roller 5 is arranged below the fixed column 4, and the bending roller 5 is rotatably connected with the inner side wall of the gear ring 7, the 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 inside of the base 1, and the cavity for the movement of the bending roller 5 is arranged in the inside of the base 1, when the gear ring 7 rotates, the bending roller 5 can move 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, therefore, when the bending roller 5 rotates around the fixed column 4, the spring piece workpiece 3 can be bent, until the bending roller 5 moves to the position closest to the avoiding groove 411, the spring piece workpiece 3 can be bent to the required shape (as shown in Figure 2 And Figure 3As shown, the two ends of the sheet metal workpiece 3 correspond to each other, and the two ends of the sheet metal workpiece 3 are located on the upper and lower sides of the backing plate 41, respectively, and then the punching head 12 punches the sheet metal workpiece 3, that is, two corresponding holes are formed on the sheet metal workpiece 3 at one time, and then the punching head 12 is withdrawn and reversely rotated to move the bending roller 5, the bending roller 5 is no longer pressed against the sheet metal workpiece 3, and the sheet metal workpiece 3 can slightly open outward under the elastic action of itself, thereby facilitating the disengagement from the fixed column 4, such as Figure 2 As shown, the side of the groove on the upper surface of the base 1 is provided with a notch, and the position of the notch corresponds to the fixed column 4 and the backing plate 41, so that the sheet metal workpiece 3 can move along the length direction of the fixed column 4, thereby realizing the disengagement from the fixed column 4.

[0033] In order to install the gear ring 7, the application also has a connecting frame 71 fixed on the inner side of the gear ring 7, and the connecting frame 71 is in the shape of "Y". The connecting frame 71 can be used for shaping and reinforcing the gear ring 7, avoiding the deformation of the gear ring 7 itself, and the middle and one end of the connecting frame 71 are respectively fixed with a sleeve one 72 and a sleeve two 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 one 72 through a bearing, and one end of the bending roller 5 passes through the inner cavity of the sleeve two 73 through a bearing, as shown. Figure 4 As shown, the sleeve one 72 can only rotate on the outside of the fixed shaft 42, so the gear ring 7 can only rotate around the fixed column 4. Since the bending roller 5 is rotationally connected with the sleeve two 73, the bending roller 5 can rotate around its own axis (i.e. revolution) while rotating around the fixed column 4 (i.e. revolution), as shown. Figure 1 As shown, when the bending roller 5 is in the position directly below the fixed column 4, the sheet metal workpiece 3 is conveyed by the conveying belt 2, one end of the sheet metal workpiece 3 passes through the gap between the fixed column 4 and the bending roller 5. Since the sheet metal workpiece 3 will gradually disengage from the conveying belt 2, the movement of the sheet metal workpiece 3 will gradually lose power, so the self-rotation of the bending roller 5 can continue to convey the sheet metal workpiece 3 at this time, until the sheet metal workpiece 3 is conveyed to the designated position. When the bending roller 5 revolves around the fixed column 4, the bending roller 5 can also roll on the surface of the sheet metal workpiece 3. At this time, the bending roller 5 and the sheet metal workpiece 3 will not cause the position of the sheet metal workpiece 3 to deviate due to sliding friction, thereby ensuring the stability of the position of the sheet metal workpiece 3.

[0034] In order to ensure that the bending roller 5 can easily bend the shell workpiece 3, the 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 outside of the gear ring 7, the protective cover 6 is mainly used for protecting the gear ring 7, the inner cavity of the protective cover 6 is rotatably provided with a driving gear 74, and the driving gear 74 is in meshing transmission with the gear ring 7, the surface of the protective cover 6 is fixed with a motor one 741 for driving the driving gear 74 to rotate, and the motor one 741 drives the driving gear 74 to rotate when working, so as to drive the gear ring 7 to rotate, because the driving gear 74 is engaged on the outside of the gear ring 7, and the diameter of the driving gear 74 is smaller than the diameter of the gear ring 7, so the connecting frame 71 between the sleeve one 72 and the sleeve two 73 can be regarded as a force-saving lever, that is, the bending roller 5 has a large torque around the fixed column 4, so as to ensure that the bending roller 5 can easily bend the shell workpiece 3 when revolving.

[0035] In order to drive the bending roller 5 to rotate, the application also has a synchronous belt 8 arranged in the inner cavity of the protective cover 6, and the two ends of the synchronous belt 8 are respectively provided with a driving pulley 81 and a driven pulley 82, the middle part of the driving pulley 81 is movably penetrated by a rotating shaft through a bearing, and one end of the rotating shaft is fixedly connected with the fixed shaft 42, the driven pulley 82 is fixed to one end of the bending roller 5, and the driving pulley 81 is rotatably connected with the sleeve one 72 through the rotating shaft. Figure 4 And Figure 5 As shown in the figure, the driving pulley 81 can drive the driven pulley 82 to rotate synchronously through the transmission of the synchronous belt 8 when the driving pulley 81 rotates, so as to realize the rotation of the bending roller 5.

[0036] In order to drive the driving pulley 81 to rotate, the application also has a motor two 83 arranged on the outside of the protective cover 6, the motor two 83 is fixed on the stand, the stand penetrates the surface of the protective cover 6 and is fixedly connected with the sleeve one 72, and the motor two 83 is used for driving the driving pulley 81 to rotate when working, and in turn drives the driven pulley 82 and the bending roller 5 to rotate, as shown in the figure. Figure 4 The stand mainly includes a circular plate and a plurality of columns, the circular plate is used for installing the motor two 83, the columns are dispersedly fixed on the end face of the sleeve one 72, and interference with the synchronous belt 8 can be avoided, when the gear ring 7 rotates, the motor two 83 and the stand will synchronously rotate, so a circular hole for the rotation of the stand is arranged on the surface of the protective cover 6, so as to avoid interference between the stand and the protective cover 6.

[0037] In order to push the shell workpiece 3 out of the upper surface of the base 1, the application also has a discharging cylinder 9 fixed on the surface of the protective cover 6, the movable end of the discharging cylinder 9 movably penetrates the protective cover 6 and extends into the inner cavity of the protective cover 6, the movable end of the discharging cylinder 9 is fixed with a protrusion, the protrusion is opposite to the edge of the shell workpiece 3 and is out of position with the bending roller 5, the discharging cylinder 9 can be telescoped, and the protrusion can be used for pushing the shell workpiece 3, so as to push the shell workpiece 3 out of the upper surface of the base 1.

[0038] To this end, the application also has a limiting ring 52 fixed outside one end of the bending roller 5, the limiting ring 52 is attached to the surface of the fixed column 4, and is used to prevent the shell fragment workpiece 3 between the fixed column 4 and the bending roller 5 from being offset along the length direction of the fixed column 4. A plurality of flexible pads 51 are attached to the surface of the bending roller 5 in an equidistant distribution. The surface of the fixed column 4 is provided with a plurality of sleeve rings 43 in an equidistant distribution. Since the fixed column 4 cannot rotate by itself, but the sleeve ring 43 can rotate around the fixed column 4, when the bending roller 5 rotates, the shell fragment workpiece 3 can be conveyed by the friction force between the flexible pad 51 and the shell fragment workpiece 3, and the friction force between the shell fragment workpiece 3 and the sleeve ring 43 can drive the sleeve ring 43 to rotate, thereby avoiding that the fixed column 4 and the shell fragment workpiece 3 generate excessive friction force and affect the normal conveying of the shell fragment workpiece 3. In addition, it should be noted that although increasing the gap between the fixed column 4 and the bending roller 5 can also avoid the conveying of the shell fragment workpiece 3 being hindered, but this will affect the bending effect of the bending roller 5 on the shell fragment workpiece 3, so the gap between the fixed column 4 and the bending roller 5 needs to be consistent with the thickness of the shell fragment workpiece 3.

[0039] To prevent the shell fragment workpiece 3 from being offset along the length direction of the fixed column 4, the application also has an annular groove for the rotation of the sleeve ring 43 formed on the surface of the fixed column 4. The surface of the sleeve ring 43 is attached with a rubber pad 431. A plurality of rolling elements 432 are movably embedded in the inner wall of the sleeve ring 43 in an annular array distribution. The rubber pad 431 and the flexible pad 51 both have a certain elastic deformation capacity, which can realize the compression of the shell fragment workpiece 3. On the one hand, it ensures that the shell fragment workpiece 3 is conveyed when the bending roller 5 rotates, and on the other hand, it avoids the position offset of the shell fragment workpiece 3 in the length direction of the fixed column 4.

[0040] To avoid the shell fragment workpiece 3 from colliding with the punching head 12 when being bent, the application also has a punching groove corresponding to the avoiding groove 411 formed on the upper surface of the base 1, and a chip removal groove 11 formed on the groove bottom of the punching groove. The punching groove is provided for the downward insertion of the punching head 12, and the chip removal groove 11 is provided for the discharge of the debris and waste generated after punching. A sliding seat 13 is horizontally slidably installed at one end of the base 1. The punching head 12 is installed on the sliding seat 13 and is driven by a cylinder to move up and down. When the sliding seat 13 slides, it can drive the punching head 12 to move horizontally, thereby avoiding the interference between the shell fragment workpiece 3 and the punching head 12 during the bending process.

[0041] To avoid the deformation of the punching groove on the base 1, the sliding seat 13 of the application is driven by another cylinder to slide close to the base 1. A boss is fixed to one side of the sliding seat 13 close to the base 1. The boss is movably inserted into the inner cavity of the chip removal groove 11. The thickness of the boss is consistent with the height dimension of the chip removal groove 11. In combination with the Figure 1 and Figure 2As shown, when the sliding base 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, so that the large impact force generated when the punching head 12 punches the spring piece workpiece 3 does not cause the upper surface of the base 1 to be concave and deformed.

[0042] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
