Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to an automatic waste discharge device for stamping molds. Background Technology

[0002] In sheet metal stamping, metal sheets are formed into target parts through processes such as punching, bending, and stretching using dies. When the upper and lower dies are closed, the sheet metal breaks and separates under shearing force. The punched target part forms a clear boundary with the surrounding material. For example, the material of the hole portion in the punching process and the scrap material after cutting the outer contour of the part become surrounding material, i.e., waste. When laying out sheet metal, single-row, double-row, or cross-row arrangements are often used to optimize material utilization. However, due to the geometric constraints of the parts (such as irregular contours and hole distribution), strip-shaped, block-shaped, or fragmented waste is unavoidable.

[0003] Currently, most waste removal methods still rely on manual labor. For example, in automated production lines, the machine needs to be stopped almost every 10 minutes to manually remove waste. If the waste is not removed in time, it will affect the subsequent production process. This method of operation seriously affects production efficiency and is time-consuming and labor-intensive.

[0038] This embodiment provides an automatic waste discharge device for stamping dies, such as... Figures 1-11 As shown, the stamping die includes an upper die 1 and a lower die 2, and the automatic waste discharge device for the stamping die includes:

[0039] The power transmission component 3 has its input end fixed below the upper mold 1 and moves vertically with the upper mold 1.

[0040] Motion conversion component 4 is connected to the output end of power transmission component 3 and is used to convert vertical motion into horizontal motion.

[0041] The slide plate assembly 5 is slidably disposed in the waste falling area of ​​the lower mold 2 and is connected to the motion conversion assembly 4;

[0042] The elastic reset component 6 has one end fixed to the side wall of the lower mold and the other end connected to the slide plate assembly.

[0043] The upper die 1 is located above the die system and connected to the moving part of the stamping press. It moves downward during the stamping process. The upper die 1 and the lower die 2 work together to complete processes such as blanking, bending, or stretching, providing the main stamping force. The lower die 2 is fixed to the worktable of the stamping press and is vertically aligned with the upper die 1. The lower die 2 serves as the support and forming base, receives the stamping force from the upper die 1, and works with the upper die to complete the sheet metal processing. It also has a waste material drop area for waste material discharge.

[0044] The input end of the power transmission component 3 is fixed below the upper die 1, and the output end is connected to the motion conversion component 4, converting the vertical motion of the upper die 1 into mechanical power and transmitting it to the motion conversion component 4. The motion conversion component 4 is located between the output end of the power transmission component 3 and the slide plate component 5, and is used to convert the vertical motion of the power transmission component 3 into a horizontal straight line, driving the slide plate component 5 to slide. When the upper die 1 moves downward, the slide plate component 5 moves in a first direction, and the elastic reset component 6 stretches; when the upper die 1 moves upward, the elastic reset component 6 resets, causing the slide plate component 5 to move in a second direction; wherein the first direction and the second direction are opposite. The slide plate component 5 is installed in the waste falling area of ​​the lower die 2 and can slide horizontally, achieving "shaking" through horizontal reciprocating motion, thereby realizing the automatic discharge of stamping waste.

[0045] In addition, one end of the elastic reset component 6 is fixed to the side wall of the lower mold 2 (such as a pre-drilled fixing hole or bracket in the side wall), and the other end is connected to the end or side of the slide plate assembly 5, forming a tension action path. The axial direction of the elastic reset component 6 is parallel to the horizontal sliding direction of the slide plate assembly 5, ensuring that the tension / reset force acts directly on the movement direction of the slide plate assembly 5.

[0046] When the upper die 1 is pressed down, the power transmission component 3 drives the slide plate component 5 to move in the first direction (e.g., to the left). At this time, the elastic reset component 6 is stretched and stores elastic potential energy. When the upper die 1 is raised, the driving force of the power transmission component 3 is released, the elastic reset component 6 releases the stored elastic potential energy, and pulls the slide plate component 5 to reset in the second direction (e.g., to the right), completing one reciprocating motion cycle. The slide plate component 5 reciprocates back and forth during the stamping process, thereby realizing the automatic discharge of stamping die waste. In addition, the slide plate component 5 is tilted.

[0047] The elastic reset component 6 converts the vertical motion of the upper mold 1 into the horizontal reciprocating vibration power of the slide plate component 5 through an energy storage and release mechanism, and ensures that the slide plate component 5 automatically resets after movement. This embodiment replaces the traditional mechanical rigid reset structure with this setting, reducing the complexity of the system, and at the same time, enhances the vibration frequency through elastic potential energy, thereby improving the waste discharge efficiency.

[0048] In this embodiment, the shaking action of the slide plate assembly 5 is automatically executed through the mechanical linkage of the power transmission assembly 3, the motion conversion assembly 4 and the elastic reset assembly 6, without the need for manual intervention to stop the machine, thus realizing the real-time discharge of waste materials and solving the problem of low efficiency caused by manual cleaning in traditional methods.

[0049] In a specific embodiment, the skateboard assembly 5 includes at least two segmented skateboards 512 hinged together by a foldable connecting structure 511. The segmented skateboards 512 have an unfolded state extending out of the lower mold 2 and a folded state housed within the lower mold 2. The foldable skateboard design allows for storage in the non-working state, such as... Figure 1 As shown, this avoids occupying the mold's closed space and improves the safety of production on the stamping site.

[0050] During the stamping process, the upper die 1 moves downward and closes with the lower die 2 to complete the stamping process. The resulting scrap falls directly onto the surface of the unfolded slide plate assembly 5 through the scrap drop area of ​​the lower die 2 (the segmented slide plate 512 is kept extended by the foldable connecting structure 511, forming a continuous inclined plane). As the upper die 1 continues to press down, the power transmission assembly 3 pushes the slide plate assembly 5 to move horizontally in the first direction through the motion conversion assembly 4. At this time, one end of the elastic reset assembly 6 is fixed to the side wall of the lower die 2, and the other end is connected to the slide plate assembly 5. Due to the displacement of the slide plate, it is stretched and stores energy. When the upper die 1 rises, the power transmission assembly 3 disengages from the upper die, and the elastic reset assembly 6 releases its elastic potential energy, pulling the slide plate assembly 5 to quickly reset in the opposite second direction. During this process, the motion conversion assembly 4 converts the vertical motion of the upper die 1 into the horizontal reciprocating motion of the slide plate assembly 5. Through the elastic impact of the spring reset and the combined action of the slide plate tilt, the slide plate assembly 5 generates high-frequency vibration, forcing the scrap to slide along the inclined surface into the collection device under the superposition of inertial force and gravity.

[0051] In a specific embodiment, the power transmission assembly 3 includes a pressure block 31 and a longitudinal rack 32. One end of the pressure block 31 is fixed to the bottom of the upper mold 1, and the other end of the pressure block 31 is connected to the longitudinal rack 32. The extending direction of the longitudinal rack 32 is parallel to the movement direction of the upper mold 1.

[0052] The pressure block 31 is fixed to the bottom of the upper die 1 (e.g., by bolts or welding) as the starting point for power transmission. Its other end is rigidly connected to the longitudinal rack 32, ensuring that the vertical movement of the upper die 1 is directly transmitted to the longitudinal rack 32. The longitudinal rack 32 extends vertically and is parallel to the movement direction of the upper die 1. Its tooth surface meshes with the motion conversion component 4. The installation position is usually located on the side of the lower die 2 or in a pre-reserved guide groove inside, ensuring the stability of the rack's vertical movement. The pressure block 31 and the longitudinal rack 32 are rigidly connected, converting the vertical stamping motion of the upper die 1 into the horizontal driving power of the slide plate assembly 5. The elastic reset component 6 is responsible for the rapid reset of the slide plate assembly 5. The two work together to achieve the horizontal reciprocating vibration required for waste discharge, while ensuring the reliability and efficiency of the mechanism's operation.

[0053] In a specific embodiment, the motion conversion component 4 includes a gear 41 and a transverse rack 42. The gear 41 meshes with the longitudinal rack 32 and also meshes with the transverse rack 42. The direction of motion of the transverse rack 42 is perpendicular to the longitudinal rack 32 and consistent with the sliding direction of the slide plate component 5.

[0054] Gear 41 is mounted on the side or internal support of the lower mold 2, with its axis fixed horizontally. It meshes with the vertical tooth surface of the longitudinal rack 32 and simultaneously with the horizontal tooth surface of the transverse rack 42. The transverse rack 42 extends horizontally, consistent with the sliding direction of the slide plate assembly 5. One end meshes with gear 41, and the other end is rigidly connected to the slide plate assembly 5 through a fixing member or slider, directly driving the slide plate to move horizontally.

[0055] Gear 41, through meshing with longitudinal rack 32, converts the vertical movement of upper mold 1 (the up-and-down movement of longitudinal rack 32) into its own rotational motion. Simultaneously, through meshing with transverse rack 42, it further converts the rotational motion of the gear into the horizontal linear motion of transverse rack 42, ultimately driving the slide plate assembly 5 to slide. Transverse rack 42 converts the rotational motion of gear 41 into horizontal linear motion, pushing slide plate assembly 5 to move in a set direction. The length of transverse rack 42 limits the horizontal sliding distance of slide plate assembly 5, ensuring that the waste discharge range matches the mold space.

[0056] During the downward pressing phase of the upper mold 1, the pressure block 31 pushes the longitudinal rack 32 downward, and the longitudinal rack 32 drives the gear 41 to rotate clockwise. The clockwise rotation of the gear 41 causes the transverse rack 42 to move horizontally in the first direction (e.g., to the left), pushing the slide plate assembly 5 to move to the left simultaneously (the elastic reset assembly 6 is stretched and stores energy). During the upward pressing phase of the upper mold 1, the pressure block 31 drives the longitudinal rack 32 upward, and the longitudinal rack 32 drives the gear 41 to rotate counterclockwise. The counterclockwise rotation of the gear 41 causes the transverse rack 42 to move horizontally in the second direction (e.g., to the right). At the same time, the elastic reset assembly 6 releases elastic potential energy, assisting the slide plate assembly 5 to quickly reset to the initial position, completing one reciprocating motion cycle.

[0057] The pressure block 31 and the longitudinal rack 32 transmit the vertical stamping motion of the upper die 1 to the gear 41. Through the bidirectional meshing of the gear and rack, the vertical motion is converted into the horizontal reciprocating motion of the slide assembly 5. The transverse rack 42, as the final power output component, directly drives the slide assembly to slide, and works with the elastic reset component 6 to achieve rapid reset, forming an automatic cycle of "pressing down - moving left to store energy, rising up - moving right to release energy". In this embodiment, precise power transmission is achieved through mechanical meshing, while elastic reset optimizes motion efficiency, ultimately achieving real-time and automated discharge of stamping waste.

[0058] In a specific embodiment, the skateboard assembly 5 includes at least two sets of skateboard units 51 arranged side by side along the length direction of the lower mold 2. Each set of skateboard units 51 includes a main skateboard 513 and at least two segmented skateboards 512. The main skateboard 513 is connected to one of the segmented skateboards 512, and adjacent segmented skateboards 512 are connected by the foldable connection structure 511.

[0059] A single set of slide plate units 51 may not be able to completely cover the entire width of the waste drop area. At least two sets of slide plate units 51 are arranged side by side to cover different areas in the width direction of the mold in sections, ensuring that the waste is fully received and shaken off, and avoiding local residue.

[0060] In a specific embodiment, the skateboard assembly 5 further includes a connecting rod 52, which is connected to the main skateboard 513 via a hinge 53. The power transmission assembly 3 has two sets, each corresponding one-to-one with the motion conversion assembly 4; one end of the connecting rod 52 is connected to one of the transverse racks 42, and the other end of the connecting rod 52 is connected to the other transverse rack 42.

[0061] The connecting rod 52 is hinged to all the main skateboard units 513 via hinges 53. Both ends of the connecting rod 52 are also connected to two transverse racks 42, forming a power transmission mechanism that allows all skateboard units 51 to move horizontally synchronously, preventing skateboard tilting or jamming due to uneven driving force on one side. Furthermore, evenly distributing the driving force of the two sets of power transmission components 3 to all skateboard units 51 reduces the stress on individual transverse racks 42, extending the lifespan of gears and racks. The hinges 53 allow the connecting rod 52 to rotate slightly when the skateboard assembly 5 is folded and unfolded, avoiding structural interference caused by rigid connections while maintaining horizontal movement rigidity.

[0062] When the upper mold 1 is pressed down, the longitudinal racks 32 of the two sets of power transmission components 3 move down synchronously, driving their respective gears 41 to rotate, which in turn drives the corresponding transverse racks 42 to move horizontally in the same direction (e.g., to the left). The two transverse racks 42 are rigidly connected by the connecting rod 52, forming a parallel drive, which forces the main slide plates 513 of the two sets of slide plate units 51 to move to the left synchronously. When the upper mold 1 is raised, the longitudinal racks 32 move up, the gears 41 reverse, and the transverse racks 42 reset in the opposite direction (e.g., to the right) with the assistance of the elastic reset component 6. The connecting rod 52 forces the two sets of transverse racks 42 to move to the right synchronously, which in turn drives the main slide plates 513 of all slide plate units 51 to move to the right synchronously.

[0063] In this embodiment, the reciprocating motion of the two sets of transverse racks 42 is transmitted to all slide plate units 51 through the connecting rod 52. Combined with the high-frequency rebound of the elastic reset component 6, the slide plate assembly 5 generates uniform vibration as a whole, thoroughly removing waste materials.

[0064] In a specific embodiment, the elastic reset component 6 includes a reset spring 61 and a buffer block 62. The buffer block 62 is disposed on the slide plate assembly 5. One end of the reset spring 61 is fixed to the side wall of the lower mold 2, and the other end of the reset spring 61 is connected to the slide plate assembly 5. One end of the reset spring 61 is fixed to the side wall of the lower mold 2 (such as a pre-drilled mounting hole or bracket on the side wall), and the other end is connected to the main slide plate 513 of the slide plate assembly 5. Its installation direction is parallel to the horizontal sliding direction of the slide plate assembly 5, ensuring that the direction of the pulling force is consistent with the movement path. The buffer block 62 is fixed to the end of the main slide plate 513. When the slide plate assembly 5 is driven by the power transmission component 3 to move in the first direction (e.g., to the left), the reset spring 61 is stretched and stores energy; when the upper mold 1 rises and the power is released, the reset spring 61 releases its elastic potential energy, pulling the slide plate assembly 5 to quickly reset in the second direction (e.g., to the right), completing the reciprocating motion cycle.

[0065] The buffer block 62 is made of polyurethane. In the automatic waste discharge device for stamping dies, the buffer block 62 uses polyurethane as the material, which has the following core advantages: the molecular structure of polyurethane gives it a high elastic modulus, which can effectively absorb the impact energy when the slide plate assembly 5 is reset (especially the instantaneous impact generated by high-frequency vibration), reduce rigid collisions between metal parts, and reduce noise; under long-term high-frequency compression, the compression set of polyurethane is lower than that of ordinary rubber, avoiding buffer failure due to material fatigue.

[0066] In a specific embodiment, the bottom of the skateboard assembly 5 is provided with at least three omnidirectional balls 7, which are arranged along the sliding direction. The omnidirectional balls 7 replace sliding friction with rolling contact, significantly reducing the friction between the skateboard assembly 5 and the lower mold 2 contact surface, ensuring smoother horizontal movement of the skateboard. Furthermore, according to mechanical design principles, three support points can uniquely define a plane, and the at least three omnidirectional balls 7 ensure that the skateboard assembly 5 maintains surface contact with the lower mold 2 at any moving position, preventing tilting or shaking due to unilateral suspension.

[0067] In a specific embodiment, the foldable connection structure 511 includes a positioning hole 5111, a bolt 5112, and a nut 5113. The positioning hole 5111 is located on the side of the segmented slide plate 512. When adjacent segments of the slide plate 512 are nested, the positioning holes 5111 overlap. The bolt 5112 passes through the positioning hole 5111 and is fixed by the nut 5113.

[0068] In the unfolded state, the ends of adjacent segmented slide plates 512 are designed with a nested structure. When fully unfolded, the positioning holes 5111 of the two slide plates completely overlap, forming a through-hole. Bolts 5112 are inserted into the aligned positioning holes 5111 and tightened with nuts 5113, making the segmented slide plates 512 rigidly connected and forming a continuous plane. At this time, the locking force of the bolts and nuts eliminates the degrees of freedom between the segmented slide plates, ensuring that the slide plate assembly 5 maintains overall rigidity during horizontal movement and vibration.

[0069] When the slide plate assembly 5 is folded, loosening the nut 5113 (not completely removing it) creates a small gap between the bolt 5112 and the positioning hole 5111, allowing the segmented slide plate 512 to rotate relative to the bolt axis. The nested ends of the segmented slide plate 512 are designed as arcs or bevels. During folding, the nested structure, such as the boss sliding along the groove, causes relative displacement of the positioning hole 5111. Since the positioning hole 5111 is an oblong hole or an arc-shaped groove (non-standard round hole), the bolt 5112 can slide within the hole, providing rotation and displacement space for folding. The segmented slide plate 512 rotates around the bolt axis to the target angle, finally folding into a compact state, reducing the overall length of the slide plate assembly 5.

[0070] This embodiment improves the production efficiency of the sheet metal stamping line, reduces manpower waste, and ensures the safety of on-site workers.

[0071] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0072] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
