Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware stamping, in particular to a hardware stamping die capable of continuous feeding. BACKGROUND

[0002] Hardware stamping is a processing technology for hardware products by means of a press and a die to exert external force on metal plates, strips and the like to make them plastically deform or separate, thereby obtaining hardware products with desired shapes, sizes and properties.

[0003] A hardware stamping die is a special tool for hardware stamping processing, which is composed of an upper die and a lower die and can cooperate with a press to process and handle metal materials and help the metal materials form desired shapes. When using the hardware stamping die, the die is first correctly installed on the press to ensure that the cooperation between the die and the press meets the processing requirements, then the metal material to be processed is placed at a specified position of the die, and the press is started. The external force generated by the press is transmitted to the die, and the die exerts force on the metal material under the action of the pressure to make the metal material plastically deform or separate. In the current application of the hardware stamping die capable of continuous feeding, the design of the discharge end of the stamping die is developed around two mainstream methods of slope guiding discharge and free-fall discharge. The slope guiding discharge is to build a guiding structure with a certain inclination angle below or outside the discharge port of the die. The material slides to the collection area by gravity after reaching the top end of the slope. The free-fall discharge method does not additionally set any guiding structure at the discharge end of the die, but only delimits a specific collection area at a suitable position directly below or below the discharge port of the die.

[0004] However, when the stamped parts are released from the constraint of the die, the motion trajectory becomes unpredictable and disordered due to the loss of effective guidance and control, and part of the stamped parts will directly impact the receiving surface in a free-fall manner due to inertia. Under high-speed impact, defects such as dents and cracks are generated. The disordered motion causes the completed stamped parts at the discharge end to frequently collide in the collection area, resulting in superimposed damage to the material surface. The damage will evolve into local peeling in the subsequent electroplating or spraying process due to the decrease in coating adhesion, ultimately significantly reducing the corrosion resistance of the product. Moreover, parts with bending or deep drawing features will elastically recover after collision, resulting in shape deviation from the design model. SUMMARY

[0035] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0037] Thirdly, the present application is described in detail in conjunction with the schematic diagram. In the detailed description of the embodiments of the present application, the sectional view of the device structure is partially enlarged without the general proportion for the convenience of description, and the schematic diagram is only an example, which should not limit the scope of protection of the present application. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0038] Embodiment 1, refer to Figure 1 Figure 4 For the first embodiment of the present application, a hardware stamping die capable of continuous feeding is provided, which comprises a discharging table 101, and further comprises:

[0039] The orientation structure 200 comprises a mounting base 201 fixedly connected to the surface of the discharging table 101, a support shaft 202 rotatably connected to the surface of the mounting base 201, a guide plate 203 fixedly connected to the surface of the support shaft 202 and having one end flush with the surface of the discharging table 101, a guide groove 2031 opened on the surface of the guide plate 203, a support plate 204 fixedly connected to the surface of the guide plate 203, a transmission assembly 205 fixedly connected to the surface of the support plate 204, and a material guiding assembly 206 fixedly connected to the transmission assembly 205. The orientation structure 200 ensures the feeding direction and lays the foundation for continuous feeding, improves the stamping efficiency, and after stamping, the hardware material slides along the guide groove 2031 on the surface of the guide plate 203.

[0040] The synchronization structure 300 comprises a buffer base 301 fixedly connected to the side of the material guiding assembly 206, a mounting groove 302 opened on the surface of the buffer base 301, two balance plates 303 fixedly connected to the surface of the mounting groove 302, a rotating shaft 304 rotatably connected to the surface of the two balance plates 303, a speed change assembly 305 fixedly connected to the surface of the rotating shaft 304, and a synchronization assembly 306 fixedly connected to the speed change assembly 305. The synchronization assembly 306 synchronizes the material guiding with the stamping action, reduces the processing error and equipment failure, and improves the precision and stability.

[0041] ​The transmission assembly 205 includes a rotating wheel 2051 fixedly connected to both ends of the support shaft 202, a first pull rope 2052 rotatably connected to the surface of the rotating wheel 2051, a guide wheel 2053 slidably connected to the surface of the first pull rope 2052, and a connecting column 2054 fixedly connected to the top end of the first pull rope 2052, one end of the guide wheel 2053 being rotatably connected to the surface of the mounting base 201. The stable power transmission reduces the friction deviation of the pull rope and ensures smooth feeding without interruption.

[0042] The surface of the guide plate 203 is fixedly connected with an embedded ring 2055, the surface of the embedded ring 2055 is slidably connected with the connecting column 2054, the surface of the embedded ring 2055 is fixedly connected with a cover 2056 through a rivet, the cover 2056 and the connecting column 2054 are fixedly connected with a compression spring 2057, and the compression spring 2057 is sleeved on the outer periphery of the first pull rope 2052. The elastic reset and stable guide are provided to ensure that the guide assembly 206 is always self-adaptive to the inclination and enhance the response capability to the weight change.

[0043] During use, the operator adjusts the inclination angle of the guide plate 203 according to the weight of the hardware material after stamping. When the included angle between the guide plate 203 and the horizontal direction becomes smaller, it indicates that the weight of the hardware material after stamping is large. When the included angle between the guide plate 203 and the horizontal direction becomes larger, it indicates that the weight of the hardware material after stamping is small. The reason is that the sliding kinetic energy of the hardware material after stamping is suppressed from the mechanical source. The gravity generated by the mass of the heavy part is already very significant. If the inclination angle is too large, the component force of the gravity along the inclined plane downward will become too large, which may cause the hardware part after stamping to accelerate downward and produce a violent end impact even in the friction state on the surface of the guide plate 203. Therefore, by reducing the angle, the downward sliding driving force can be directly and effectively limited, so that the hardware part is in a suppressed state from the start stage. Combined with the high damping effect of the self-weight on the friction mechanism, the heavy part can be ensured to slide smoothly at a low speed throughout the process.

[0044] Conversely, for the light part, the small gravity leads to insufficient driving force, which is prone to jamming. Therefore, the angle between the guide plate 203 and the horizontal line needs to be increased to provide sufficient starting and sliding power, and the obtained high speed is consumed by the speed change assembly 305, so as to finally realize soft landing into the collection area below the buffer base 301. The collection area can be a collection box, a collection frame, etc. The above-mentioned adjustment of the inclination angle is adjusted by the operator according to the mass of the hardware material part after stamping in the actual stamping process, so that the hardware material part after stamping can enter the collection area.

[0045] In the adjusting process, the connecting part of the guide plate 203 and the discharging table 101 is connected by soft rubber material, which has bending flexibility. During the angle adjusting process, the connecting part of the guide plate 203 and the discharging table 101 always keeps horizontal with the discharging table 101. When the inclination angle of the guide plate 203 becomes larger, the guide plate 203 drives the support shaft 202 to rotate clockwise, the rotating wheels 2051 at both ends of the support shaft 202 rotate clockwise, the length of the first pull rope 2052 is extended, the first pull rope 2052 moves in the inner embedded ring 2055 through the hole on the surface of the cover 2056 under the guidance and support of the guide wheel 2053 and the elastic action of the compression spring 2057, and the connecting column 2054 connected to one end of the first pull rope 2052 moves away from one end of the inner embedded ring 2055. On the contrary, when the inclination angle of the guide plate 203 becomes smaller, the guide plate 203 drives the support shaft 202 to rotate counterclockwise, the rotating wheels 2051 at both ends of the support shaft 202 rotate counterclockwise, the length of the first pull rope 2052 is shortened, the first pull rope 2052 moves in the inner embedded ring 2055 through the hole on the surface of the cover 2056 under the guidance and support of the guide wheel 2053 and the elastic action of the compression spring 2057, and the connecting column 2054 connected to one end of the first pull rope 2052 moves close to one end of the inner embedded ring 2055, thereby providing power source for the material guiding assembly 206.

[0046] The guide plate 203 with adjustable inclination angle and the material guiding assembly 206 provide a controllable and orderly transfer path for the stamping parts, avoid free falling and disorderly collision, the guide plate 203 adjusts the angle according to the weight of the parts, the angle is reduced to suppress the initial kinetic energy when the weight is large, the angle is increased to avoid jamming when the weight is light, and the sliding speed of all parts is controlled, the variable speed assembly 305 is used at the end of the sliding to effectively consume the energy, the soft landing of the stamping parts is realized, and the stamping parts enter the mobile phone area, thereby completely eliminating the surface defects such as pits and cracks caused by high-speed impact, reducing the damage of secondary collision in the collection area, and protecting the surface integrity of the material. At the same time, the stable sliding process avoids the elastic recovery of the bent or stretched parts caused by violent collision, ensures that the geometric size of the parts is consistent with the design model, and improves the product precision and qualification rate.

[0047] Embodiment 2, refer to Figure 1 Figure 5 ​For the second embodiment of the application, which is different from the first embodiment, the material guiding assembly 206 includes a material guiding plate 2061 fixedly connected to one end of the connecting column 2054, a positioning column 2062 rotatably connected to the surface of the material guiding plate 2061, fixed pieces 2063 fixedly connected to both ends of the positioning column 2062, and a soft rubber head 2064 fixedly connected to one end of the material guiding plate 2061, and one end of the fixed pieces 2063 is fixedly connected to the surface of the supporting plate 204. The material guiding plate 2061 cooperates with the positioning column 2062 and the fixed pieces 2063 to achieve stable support, and the soft rubber head 2064 can buffer the impact of the parts, ensure the stability of the material guiding process, and reduce the damage of the parts.

[0048] Further compared with the first embodiment, the surface of the supporting plate 204 is fixedly connected with columnar pins 2066 arranged in a linear array, springs 2065 are fixedly connected between the columnar pins 2066 and the material guiding plate 2061, a stop groove 2067 is formed in the surface of the material guiding plate 2061, a pin groove 2070 is formed in the surface of the stop groove 2067, a pin rod 2068 is slidably connected to the surfaces of the stop groove 2067 and the pin groove 2070, and a linkage rod 2069 is rotatably connected to the surface of the pin rod 2068. The columnar pins 2066 and the springs 2065 assist the material guiding plate 2061 to reset, and the stop groove 2067, the pin groove 2070, the pin rod 2068, and the linkage rod 2069 realize the synchronous action of multiple material guiding plates 2061, improve the consistency of material guiding, and adapt to more scenes.

[0049] In the process of adjusting the inclination angle of the guide plate 203 by the operator, whether the inclination angle becomes smaller or larger, the connecting column 2054 will move in the embedded ring 2055 and provide power for the rotation of the material guiding plate 2061 in the positioning column 2062.

[0050] It is worth mentioning that the surface of the guide plate 2061 near one end of the unloading table 101 is connected to one end of the connecting column 2054, which is the bottommost power transmission member. This power transmission member is connected to other guide plates 2061 through the pin 2068 and the linkage rod 2069. When the inclination angle of the guide plate 203 increases, it indicates that the quality of the stamped hardware parts is light. The connecting column 2054 moves away from the embedded ring 2055. The guide plate 2061 is fixed and supported by the positioning column 2062 and the fixed sheet 2063, and is driven to move by the connecting column 2054. This makes the angle between the guide plate 2061 and the support plate 204 increase. The guide plate 2061 expands towards the center line of the guide plate 203. At this time, the power transmission member drives the linkage rod 2069 to move in the stop groove 2067 with the pin 2068 as the support point, and drives other guide plates 2061 to expand by the same angle. On the one hand, the soft rubber head 2064 at the top of the expanded guide plate 2061 can act on the surface of the object parts sliding down the surface of the guide plate 203, which has a positioning function for these hardware parts. On the other hand, when the inclination angle increases, the friction between the surface of the guide plate 203 and the surface of the hardware material ensures that the hardware material enters the collection area smoothly after the second speed reduction of the speed change assembly 305.

[0051] Conversely, when the inclination angle of the guide plate 203 decreases, it indicates that the quality of the stamped hardware parts is heavy. The connecting column 2054 moves towards the embedded ring 2055. The guide plate 2061 is fixed and supported by the positioning column 2062 and the fixed sheet 2063, and is driven to move by the connecting column 2054. This makes the angle between the guide plate 2061 and the support plate 204 decrease. The guide plate 2061 contracts towards the center line of the guide plate 203. At this time, the power transmission member drives the linkage rod 2069 to move in the stop groove 2067 with the pin 2068 as the support point, and drives other guide plates 2061 to contract by the same angle. On the one hand, the soft rubber head 2064 at the top of the contracted guide plate 2061 can reduce the contact with the surface of the object parts sliding down the surface of the guide plate 203, which has a simple positioning function for these hardware parts. On the other hand, when the inclination angle decreases, the friction between the surface of the guide plate 203 and the surface of the hardware material ensures that the hardware material enters the collection area smoothly after the second speed change of the speed change assembly 305.

[0052] The angle adjustment of the guide plate 203 is transmitted to the material guide plate 2061 assembly through the linkage mechanism, realizing self-adaptive control of the continuous transmission process of stamping parts of different weights. The material guide plate 2061 intelligently expands or shrinks with the change of angle, effectively positioning and buffering the parts through the soft rubber head 2064, and cooperates with the variable speed assembly 305 to jointly adjust the sliding speed, completely avoiding the disordered movement and free fall impact of the parts after leaving the mold. The hardware stamping parts always slide smoothly under controlled guidance, eliminating the pits and cracks caused by high-speed impact on the receiving surface, eliminating secondary collisions between parts in the collection area, and ensuring the integrity of the material surface.

[0053] Moreover, the flexible soft rubber head 2064 also plays a role in cleaning the surface of the parts during the buffering process, reducing the introduction of impurities on the surface of the hardware stamping parts into the collection area, effectively suppressing noise pollution caused by part collision during the entire transmission process, and preventing metal debris from splashing, improving the working environment and enhancing the operation safety.

[0054] The rest of the structure is the same as that of Example 1.

[0055] Example 3, refer to Figure 1 Figure 12 This is the third embodiment of the present application, which is different from the second embodiment: the variable speed assembly 305 includes a variable speed roller 3051 fixedly connected to the surface of the rotating shaft 304 and located between the two balance plates 303, a sliding circular plate 3052 fixedly connected to both ends of the rotating shaft 304, a plurality of blocking blocks 3058 fixedly connected to the surface of the sliding circular plate 3052, and a sliding groove 3053 opened on the surface of the buffer base 301 and located on the side of the sliding circular plate 3052. The mechanical control of the conveying speed is realized through the cooperation of the variable speed roller 3051 and the sliding circular plate 3052, and the sliding groove 3053 structure provides guidance for buffer adjustment, ensuring that stamping parts of different weights can realize stable dissipation of kinetic energy through rolling contact.

[0056] Compared with Example 2, further, the surface of the sliding groove 3053 is slidingly connected with a limiting block 3054, the surface of the limiting block 3054 is fixedly connected with a supporting plate 3055, the surface of the supporting plate 3055 is fixedly connected with a linear array of variable speed wedge blocks 3056, and the surface of the supporting plate 3055 is fixedly connected with a buffer plate 3057 located directly below the variable speed roller 3051. The sliding of the limiting block 3054 along the sliding groove 3053 ensures the vertical movement precision of the supporting plate 3055, the linear array of the variable speed wedge blocks 3056 forms multi-point locking control of the sliding circular plate 3052, and the buffer plate 3057 directly receives the impact of the stamping parts and transmits the pressure to the variable speed roller 3051, forming a buffer system.

When the punch 107 returns, the buffer 104 fixed to the top plate 105 releases the stored energy, assists the upper die base 103 to reset stably, and avoids rigid impact. The formed punched part is guided out of the unloading table 101 on the surface of the lower die base 102. The working principle of this part is prior art, and those skilled in the art can clearly understand it, which will not be described here.

[0060] In use, the angle adjustment of the guide plate 203 is controlled by the synchronous assembly 306, the leg 3061 in the synchronous assembly 306 is shortened, and because the connection between the buffer base 301 and the guide plate 203 and the support plate 204 at the connection are made of soft rubber material, which has bending toughness, under the support of the leg 3061, the buffer base 301 always keeps horizontal with the blanking line of the hardware parts after stamping, so as to ensure that the hardware parts can smoothly enter the collection area, therefore, when the length of the leg 3061 exposed to the outside world is shortened, it indicates that the buffer base 301 is descending, and the included angle between the guide plate 203 and the horizontal direction is increased, the support shaft 202 and the rotating wheel 2051 both rotate clockwise, the guide plate 2061 moves towards the direction of approaching the center line of the guide plate 203, and expansion is realized; when the length of the leg 3061 exposed to the outside world is lengthened, it indicates that the buffer base 301 is ascending, and the included angle between the guide plate 203 and the horizontal direction is decreased, the support shaft 202 and the rotating wheel 2051 both rotate counterclockwise, the guide plate 2061 moves towards the direction of moving away from the center line of the guide plate 203, and contraction is realized.

[0061] When the produced hardware stamping material is light in quality, the operator presses the pressing handle 3071 on the surface of the connecting square cylinder 3065 by hand, the pressing handle 3071 extrudes the pressing plate 3070, the extruded pressing plate 3070 pulls the pull piece 3068 and the positioning rod 3067 to move on the bridging plate 3066 in the direction of the pressing handle 3071 under the traction of the second pull rope 3069, the positioning rod 3067 is separated from the positioning hole 3064 on the surface of the leg 3061, then the buffer base 301 is moved downward, the leg 3061 moves upward relative to the buffer base 301 on the surface of the open loop sleeve 3063, and when the length of the leg 3061 exposed to the outside world is shortened, the leg 3061 drives the buffer plate 3057 to move upward, the upward moving buffer plate 3057 drives the variable speed wedge block 3056 on the surface of the supporting plate 3055 to move upward along the vertical direction, and then is clamped in the space formed by the adjacent two sliding round plates 3052, preventing the variable speed roller 3051 from rotating on the rotating shaft 304, when the light quality hardware stamping material slides down, because the inclination angle of the guide plate 203 is large, the slope of the guide plate 203 becomes steep, and when the hardware material slides to the buffer plate 3057, it also has a speed and acceleration of movement, when the hardware material slides to the surface of the buffer plate 3057, the upward moving buffer plate 3057 acts on the surface of the variable speed roller 3051, and the frictional resistance of the locking structure that the variable speed wedge block 3056 and the sliding round plate 3052 cause the variable speed roller 3051 to be unable to rotate, is converted into a reverse brake on the bottom of the hardware material through the variable speed roller 3051, the variable speed roller 3051 slightly rotates or is stationary, forcing the material to slow down, so that it smoothly falls into the collecting device at a low speed, and the risk of bouncing and colliding is eliminated.

[0062] When the produced hardware stamping material is heavy, the operator presses the pressing handle 3071 connected to the surface of the square cylinder 3065 by hand, then moves the buffer base 301 upward, the supporting leg 3061 moves downward when the surface of the open loop sleeve 3063 is opposite to the buffer base 301, the length of the supporting leg 3061 exposed to the outside changes, then the supporting leg 3061 drives the buffer plate 3057 to move downward, the variable speed wedge 3056 on the surface of the supporting plate 3055 moves downward along the vertical direction, then separates from the space formed by the adjacent two sliding round plates 3052, that is, separates from the surface of the blocking block 3058, when the heavy hardware stamping material slides downward, due to the small inclination angle of the guide plate 203, the slope of the guide plate 203 becomes stable, when the hardware material slides to the buffer plate 3057, it still has speed and acceleration, when the hardware material slides to the surface of the buffer plate 3057, due to the heavy weight, the friction between the surface of the hardware material and the surface of the guide plate 203 becomes large, when it slides to the surface of the buffer plate 3057, it may slide at low speed, when it slides to the surface of the variable speed roller 3051, it can drive the variable speed roller 3051 to rotate, and the hardware material is finally stably conveyed to the edge of the collection area along with the slow rotation of the variable speed roller 3051, and then falls vertically into the box by gravity after losing the horizontal speed, so as to realize the impact-free transition.

[0063] The operator adjusts the height of the buffer base 301 according to the weight of the stamping part, synchronously changes the inclination angle of the guide plate 203 and the unfolding state of the guide plate 2061, realizes the self-adaptive control of the transmission path, and adopts large-angle sliding and forced buffering through the locked variable speed roller 3051 for the light weight parts, and adopts small-angle stable sliding and flexible conveying through the rotatable variable speed roller 3051 for the heavy weight parts, so that all the parts can fall vertically into the collection area in the state of approximate zero impact, which completely eliminates the free-fall impact, secondary collision and surface scratch, guarantees the surface integrity of the parts, and provides a substrate for the subsequent surface treatment process.
