Description

Technical Field

[0001] The invention relates to the technical field of metal stamping, in particular to a high-precision spring special stamping machine. Background Art

[0002] High-precision springs are springs with very small wire diameters, strong stability, and stable force values. By placing the material on a workbench and utilizing the interaction between upper and lower molds to press the material into the desired shape, it is possible to ensure that the size, shape, and performance of the spring meet the design requirements. They are widely used in automotive manufacturing, electronics, machinery manufacturing, medical equipment, aerospace, and other fields. As a type of high-precision spring, diaphragm springs have the characteristics of high stiffness, high strength, and high precision, which makes them widely used in various mechanical equipment and instruments.

[0003] The Chinese patent with announcement number CN221289214U provides a car diaphragm spring processing tool, which belongs to the field of diaphragm spring technology. It solves the problem that the diaphragm spring is easy to deform and cannot dissipate heat during use of the current tool. The car diaphragm spring processing tool includes a base, the top of the base is slidably connected to a receiving shell, the bottom of the receiving shell is fixed with a connecting shell, and the other end of the connecting shell passes through the interior of the base and is slidably connected to the inner wall of the penetration point. The utility model can rotate the receiving shell to a suitable angle through the cooperation of the connecting shell and the power mechanism, thereby dissipating the pressure on the diaphragm spring during the stamping process and reducing the damage to the diaphragm spring. At the same time, with the cooperation of the transmission mechanism and the heat dissipation mechanism, the interior of the base can be dissipated, thereby avoiding the staff from being in a high temperature environment for a long time, which not only improves comfort but also reduces the impact on the staff's body.

[0004] The above-mentioned patents and some existing technologies have the following problems when actually used: the punch penetrates the workpiece and punches out a notch of a fixed shape in the workpiece, and the waste generated during the stamping process may remain in the groove of the receiving shell and cannot be discharged. With continuous use, the waste in the groove of the receiving shell gradually increases, which may cause the punch to be unable to stamp the workpiece normally, and it is necessary to frequently pause the stamping to clean the waste; at the same time, when the receiving shell is rotated, the punch needs to be separated from the workpiece to be processed, and when a stamping is completed, the punch will penetrate the workpiece. When moving upward, the punch needs to gradually separate from the diaphragm spring, which may drive the diaphragm spring to move during the upward movement of the punch. When the diaphragm spring falls onto the receiving shell due to its own weight, the position of the diaphragm spring on the receiving shell may deviate from the initial position. Therefore, after the receiving shell drives the diaphragm spring to rotate, when the punch stamps the diaphragm spring again, the notch punched on the diaphragm spring may deviate from the pre-set position, resulting in uneven distribution of the notches of the final diaphragm spring product, which may affect the performance of the diaphragm spring and make it unable to be put into normal use.

[0005] Therefore, the present invention provides a high-precision spring-specific punching machine. Summary of the Invention

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will be further described below in conjunction with specific implementation methods. Figures 1-9 As shown, a high-precision spring-specific stamping machine described in the present invention includes a frame 1 and an operating table 2, the operating table 2 is fixedly connected to the frame 1, a connecting plate 4 is fixedly installed on the top of the operating table 2, a punch 3 is provided on the top of the connecting plate 4, an adjusting mechanism 5 is installed on the top of the connecting plate 4, the adjusting mechanism 5 includes a movable seat 51 rotatably connected to the connecting plate 4; a stamping mechanism 6 is provided on the top of the movable seat 51, the stamping mechanism 6 includes a connecting seat 61 fixedly connected to the top of the movable seat 51; the top of the movable seat 51 and the top of the connecting seat 61 are both umbrella-shaped, a group of punching holes 62 are opened through the top of the connecting seat 61, and a group of mounting grooves 63 are opened on the top of the movable seat 51; an auxiliary mechanism 7 is provided in the mounting groove 63, the auxiliary mechanism 7 includes a plurality of movable arc plates 71 movably connected to the movable seat 51, the plurality of movable arc plates 71 are umbrella-shaped as a whole, and the height gradually decreases from the center to the outside, and a single movable arc plate 71 is semicircular; a limiting mechanism 8 is provided on the top of the connecting seat 61, A group of connecting blocks 81 are fixedly connected to the outer wall of the seat 61, and a slider assembly 84 is slidably connected inside the connecting block 81. The upper end of the connecting block 81 is slidably connected to a limit ring 86; the stamping mechanism 6 is assembled to punch the workpiece fixed on the connecting seat 61 through the punch 3; the limiting mechanism 8 is assembled to limit the workpiece through the cooperation of the limiting ring 86 and the slider assembly 84 to avoid changes in the positional relationship between the workpiece and the connecting seat 61 during the stamping process; the adjusting mechanism 5 is assembled to control the rotation of the connecting seat 61 and cooperate with the punch 3 to achieve batch stamping; the auxiliary mechanism 7 is assembled to discharge the waste through the movable arc plate 71 after completing a stamping. At the same time, when the block waste falls onto the movable arc plate 71, the movable arc plate 71 shakes, which is conducive to the discharge of the waste generated by stamping, and the buffering shaking of the movable arc plate 71 can effectively reduce or absorb the impact force of the waste, so that the speed of the waste is rapidly reduced, which not only utilizes the power for discharge, but also protects the safety of equipment and surrounding personnel.

[0036] In this embodiment, when the workpiece to be processed is placed on the top of the connecting seat 61, the size of the workpiece is adapted to the connecting seat 61. When the control limit ring 86 slides downward, the limit ring 86 abuts against the second slider 842, so that the slider assembly 84 slides, and the lower inclined surface of the first slider 841 abuts against the top of the edge of the workpiece. Under the restriction of multiple first sliders 841, the workpiece is in a fixed state. After the punch 3 completes a punching, it moves upward without affecting the position of the workpiece. After the punch 3 is separated from the workpiece, the motor is controlled to make the worm 55 rotate rapidly, and the worm 55 drives the worm wheel 54 to rotate rapidly, thereby making the movable seat 51 rotates a certain angle driven by the worm gear 54, and the punch 3 can punch the workpiece at a different position when punching it again. The waste generated during punching and the molding waste fall onto the movable arc plate 71, and the small particle waste generated in the process may fall onto the movable arc plate 71 or the bottom of the installation groove 63. The molding waste and the small particle waste slide out of the movable seat 51 through the inclined movable arc plate 71 and the bottom of the installation groove 63. The centrifugal force generated by the rapid rotation of the movable seat 51 is more conducive to the discharge of the waste. The buffering shaking of the movable arc plate 71 can realize multi-mode waste discharge functions.

[0037] like Figure 4-Figure 6 As shown, the adjusting mechanism 5 also includes a movable bin 52 opened at the bottom of the movable seat 51, and a gear ring 53 is provided on the inner wall of the movable bin 52. A motor is installed on the top of the connecting plate 4, and a worm 55 is fixedly connected to the output end of the motor. A worm gear 54 is provided on one side of the worm 55, and the worm gear 54 is rotatably connected to the connecting plate 4. The worm gear 54 cooperates with the worm 55, and the side of the worm gear 54 away from the worm 55 is meshed with the gear ring 53; the worm gear 54, the worm 55, and the motor are all located inside the movable bin 52, and the side wall of the movable seat 51 is provided with heat dissipation holes, which are connected to the movable bin 52; a fixed column 41 is fixedly connected to the top of the connecting plate 4, and the fixed column 41 passes through the movable seat 51 and the connecting seat 61, and the movable seat 51 and the connecting seat 61 are both rotatably connected to the fixed column 41; the bottom of the connecting seat 61 is attached to the top of the movable seat 51, and the punching 62 corresponds to the mounting groove 63.

[0038] In this embodiment, when the movable seat 51 needs to be adjusted, the motor is turned on to rotate the worm 55, and the worm 55 drives the worm wheel 54 to rotate. The worm wheel 54 is engaged with the ring gear 53 on the inner wall of the movable seat 51. When the worm wheel 54 rotates, it drives the ring gear 53, so that the movable seat 51 rotates on the connecting plate 4. When the movable seat 51 rotates, it drives the connecting seat 61 fixedly connected to its top to rotate. By controlling the rotation of the worm 55, the degree of rotation of the worm 55 is the same each time, so that the movable seat 51 rotates the same angle each time, so that The notches punched out by the punch 3 can be evenly distributed on the diaphragm spring without affecting the performance of the finished workpiece. The multiple heat dissipation holes set on the side wall of the movable seat 51 are used for heat dissipation of the movable bin 52 to avoid excessive temperature inside the movable bin 52 when the motor is working. The punch 3 does not contact the movable arc plate 71 when penetrating the diaphragm spring workpiece. After the diaphragm spring is penetrated, the waste material in the shape of the punching hole 62 falls onto the movable arc plate 71 in the mounting groove 63, and the long strip of waste material slides out of the movable seat 51 through the inclined movable arc plate 71.

[0039] like Figure 7-Figure 9 As shown, the limiting mechanism 8 also includes a through slot 82 opened in the connecting block 81, the bottom of the slider assembly 84 is slidably connected to the bottom of the through slot 82, and second springs 85 are fixedly connected on both sides of the slider assembly 84, and the end of the second spring 85 away from the slider assembly 84 is fixedly connected to the side wall of the through slot 82, and the second spring 85 is in a compressed state in the initial state; the slider assembly 84 includes a first slider 841 and a second slider 842, the first slider 841 and the second slider 842 are fixedly connected, and the top and bottom of the end away from the first slider 841 and the second slider 842 are both inclined; a second slide groove 83 is opened on the side of the upper end of the connecting block 81 away from the connecting seat 61, and a clamping block 861 is fixedly connected to the inner side of the limiting ring 86, and the clamping block 861 is slidably connected to the second slide groove 83.

[0040] When the cam 842 is in the closed position, the spring 85 is in the closed position, and the spring 85 is in the closed position, so that the cam 842 is in the closed position, and the spring 85 is in the closed position.

[0041] like Figure 3-Figure 6When the cam 72 is in the unlocked position, the locking cam 72 is in the unlocked position, and the lock 71 is locked. As shown in FIG, the auxiliary mechanism 7 also includes a fixed plate 73 fixedly connected to both sides of the movable arc plate 71. The fixed plate 73 is located at the end of the movable arc plate 71 with a higher horizontal height. A first spring 74 is fixedly connected to the bottom of the fixed plate 73. A first slide groove 72 is respectively provided on both sides of the mounting groove 63. The end of the first spring 74 away from the fixed plate 73 is fixedly connected to the bottom of the first slide groove 72. The fixed plate 73 is slidably connected to the first slide groove 72. Fixed shafts 75 are fixedly connected to both sides of the end of the movable arc plate 71 away from the fixed plate 73. The fixed shaft 75 is rotatably connected to the movable seat 51. The first spring 74 is in a stretched state in the initial state; the bottom of the mounting groove 63 is tilted, and the movable arc plate 71 is located inside the mounting groove 63.

[0042] When the locking cam 75 is in the unlocking state, the locking cam 75 is in the unlocking state, and the locking cam 75 is in the unlocking state, so that the locking cam 75 is locked and the locking cam 75 is locked. After sliding out of the mounting groove 63, it can enter the collection box, while the long strip of molding waste slides out directly and falls to the outside of the connecting plate 4. It can also be cleaned during the stamping process. A small part of the granular waste generated during stamping may fall to the bottom of the mounting groove 63, and the movable arc plate 71 is shaken for a limited time and amplitude when impacted by the long strip of waste. Therefore, some waste may adhere to the movable arc plate 71 and fail to slide out in time. When the movable seat 51 rotates, the centrifugal force it generates drives some of the waste that may not be discharged in time on the movable arc plate 71 and the bottom of the mounting groove 63, and moves it when the movable seat 51 rotates, which is conducive to the full discharge of the waste.

[0043] Working principle: When in use, place the diaphragm spring workpiece to be processed on the top of the connecting seat 61, the edge of the workpiece abuts against the side wall of the connecting block 81, pull the limiting ring 86 down, and the block 861 slides downward in the second slide groove 83. The lower end of the limiting ring 86 abuts against the upper inclined surface of the second slider 842, so that the slider assembly 84 is pushed toward the connecting seat 61, the second spring 85 is stretched, and the first slider 841 is pushed out of the through groove 82. The lower inclined surface of the first slider 841 abuts against the workpiece to fix the workpiece. When the punch 3 completes a punching of the workpiece, the punch 3 moves up and separates from the workpiece. The workpiece cannot be driven by the punch 3 under the restriction of the limiting mechanism 8 and is still fixed on the connecting seat 61. The worm 55 is controlled to rotate to a certain extent. The worm 55 drives the worm wheel 54 to rotate, so that the gear ring 53 meshing with the worm wheel 54 is driven, thereby causing the movable seat 51 to rotate on the connecting plate 4. The workpiece fixed on the connecting seat 61 rotates a certain angle accordingly, and other positions of the workpiece are stamped. After all the stamping work is completed, the limiting ring 86 is moved up, the second spring 85 is reset, the slider assembly 84 slides, and the first slider 841 is separated from the workpiece, and the processed workpiece can be removed;

[0044] During stamping, the punch 3 penetrates the workpiece, and the waste generated during the stamping process falls into the mounting groove 63. When the punched-out molding waste falls onto the movable arc plate 71, the first spring 74 is compressed under the impact of the falling waste, and then rebounds, causing the upper end of the movable arc plate 71 to shake, driving the fixed shaft 75 at the lower end of the movable arc plate 71 to rotate, accelerating the discharge of waste from the mounting groove 63, and cooperating with the centrifugal force generated when the movable seat 51 rotates, which is conducive to assisting the discharge of molding waste and granular waste, and avoiding the situation where some waste cannot fall on the movable arc plate 71.

[0045] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention.
