Description

Technical Field

[0001] This utility model belongs to the field of hardware processing technology, specifically relating to a cleaning auxiliary device for hardware stamping dies. Background Technology

[0002] During the operation of metal stamping dies, metal shavings are sometimes generated during the stamping process, and these shavings can easily remain inside the die cavity. Since the die cavity is a key component in the mold that forms the recessed shape, the residual metal shavings will be squeezed by the interaction of the punch and die during subsequent stamping, causing fine scratches or dents on the surface of the processed product, seriously affecting the product's appearance quality and precision. Currently, traditional cleaning methods mostly use compressed air to directly blow away the shavings. During this process, the shavings are easily scattered by the airflow, not only polluting the workshop environment, but also making it difficult to completely remove some fine particles. Shavings remaining within the complex structure of the die cavity can still cause product defects. Furthermore, manual cleaning is inefficient, and frequent mold disassembly can lead to component wear, affecting mold life and production efficiency. Therefore, there is an urgent need for a cleaning auxiliary device that can efficiently and accurately remove residual metal shavings from the die cavity while avoiding shavings scattering and pollution, in order to solve the product quality hazards and cleaning problems existing in current technologies.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] like Figure 1-5 As shown, a cleaning auxiliary device for metal stamping dies includes: The jet pipe 11; the jet head 12 is disposed at one end of the jet pipe 1; the splash shield 21 is conically fitted onto the jet pipe 1, and the jet head 2 is located inside the splash shield 21, and two ventilation slots 22 are provided on the splash shield 21; two filters 23 are respectively disposed inside the ventilation slots 22; the sealing ring 24 is disposed at the opening of the splash shield 21; and the collection assembly is disposed inside the ventilation slots 22 for collecting debris inside the splash shield 21.

[0018] The jet pipe 11 serves as the core channel for airflow transmission, with one end connected to an external air source (such as compressed air equipment) and the other end fixedly connected to the jet head 12. Compressed air is delivered through the internal airflow channel, providing power for the cleaning process. The jet head 12 is located at the end of the jet pipe 11, inside the splash guard 21, with an airflow channel at its end facing the mold cavity. As the airflow output terminal, it directly applies impact force to the debris inside the mold cavity, causing it to detach from the mold surface, thus achieving initial cleaning.

[0019] The splash guard 21 is conical and fitted around the outside of the jet pipe 11. The splash guard 21 is made of transparent material, with its opening facing the mold surface. The jet head 12 is completely contained within the guard, and two ventilation slots 22 are provided on its side wall. The conical guard creates a closed or semi-closed purging space, with the opening fitting against the mold surface to form a localized isolation area. As the airflow carries debris within the guard, the ventilation slots 22 facilitate the directional discharge of both airflow and debris. This prevents debris from being dispersed into the workshop environment during purging, reducing dust pollution.

[0020] The filters 23 are arranged in pairs inside the two vent slots 22 of the splash shield 21, covering the cross-section of the vent slots. As a physical filtration barrier, they intercept debris carried in the airflow, preventing debris that is not completely captured by the collection component from being discharged from the splash shield 21 through the vent slots 22. The filters 23 and the collection component form a double barrier, ensuring that debris in the airflow is fully trapped and preventing it from escaping into the external environment.

[0021] A sealing ring 24 is located at the opening edge of the splash guard 21 and is typically made of elastic rubber or silicone. When the splash guard 21 is close to the mold surface, the sealing ring 24 is compressed and deformed, filling the gap between the guard and the mold. This prevents airflow from leaking from the edge of the guard during purging and ensures that debris is confined inside the splash guard 21.

[0022] Overall, the jet pipe 11 and jet head 12 use airflow to detach debris from the mold surface. The anti-splash cover 21 and sealing ring 24 form a closed cleaning space to limit the spread of debris. When the airflow carries debris through the ventilation channel 22, the collection component preferentially adsorbs or intercepts the debris. The filter screen 23 acts as a rear barrier to prevent the leakage of debris. Finally, a multi-level cleaning process of "blowing-isolation-collection-filtration" is achieved, ensuring that the debris is completely controlled inside the device and effectively solving the problem of debris residue and dispersion in the mold cavity.

[0023] Furthermore, the collection components include: The electrostatic dust removal rod 31 is disposed inside the ventilation slot 22, and the electrostatic dust removal rod 31 is located on the side of the filter screen 23 near the inside of the splash guard 21.

[0024] The electrostatic dust removal rod 31 is disposed inside the ventilation slot 22 of the splash guard 21, and is located on the side of the filter screen 23 closest to the inside of the splash guard 21, i.e., the inner side of the filter screen, forming a front-to-back stage with the filter screen 23. The electrostatic dust removal rod 31 generates an electrostatic field through the tip discharge effect or an external power supply, causing the debris particles carried in the airflow of the ventilation slot 22 to adsorb charges and become charged particles.

[0025] Furthermore, the electrostatic dust removal rod 31 includes two rod heads 311 and a rod body 312, with the two rod heads 311 located at both ends of the rod body 312 respectively; The splash shield 21 has two through holes 32 that are respectively connected to two ventilation slots 22, and the shape of the through holes 32 matches the rod head 311; The electrostatic dust removal rod 31 is slidably disposed inside the ventilation groove 22 through the through hole 32, and the rod head 311 is sealed and abutted against the inner wall of the through hole 32.

[0026] The rod body 312, as the main body for generating static electricity, is usually made of conductive material. Its surface can generate an electrostatic field through a discharge needle or ionization device to adsorb charged debris in the airflow. The rod head 311 is located at both ends of the rod body 312, and its shape matches the through hole 32. The material has both conductivity and sealing properties, such as rubber-coated metal.

[0027] Two ventilation slots 22 of the splash guard 21 are respectively provided with through holes 32. The axis of the through holes 32 is consistent with the direction of the ventilation slots 22, ensuring that the electrostatic dust removal rod 31 slides into the horizontal direction. The electrostatic dust removal rod 31 passes through the through holes 32 through the side wall of the splash guard 21, with the rod body 312 completely located inside the ventilation slots 22. The rod head 311 is exposed on the outside or inside of the splash guard 21, forming a sealed fit with the inner wall of the through hole 32. This allows the electrostatic dust removal rod 31 to be detachable. Operators can directly pull the electrostatic dust removal rod 31 through the handle 33, allowing it to slide out of the ventilation slots 22 along the through holes 32, without disassembling the splash guard 21 or the mold, to clean the debris adsorbed on the surface of the rod body 312.

[0028] Furthermore, a handle 33 is connected between the rod heads 311 located at the through hole 32 of the two electrostatic dust removal rods 31.

[0029] Two electrostatic dust removal rods 31 can be pulled simultaneously using a single handle 33, causing them to slide synchronously into or out of the ventilation slot 22 along their respective through holes 32, avoiding the tediousness of operating them one by one. For example, during cleaning, simply hold the handle 33 and pull it outward to remove both electrostatic dust removal rods 31 at once, greatly improving maintenance efficiency.

[0030] Furthermore, the splash guard 21 is provided with a guide strip 34 that matches the rod head 311 at the ventilation groove 22, and the guide strip 34 is located at the lower part of the ventilation groove 22 near the opening inside the splash guard 21.

[0031] When the electrostatic dust removal rod 31 slides into the ventilation groove 22 along the through hole 32, the bottom of the rod head 311 contacts the guide bar 34. The guide bar 34 guides the rod body to move smoothly in the preset direction through physical limiting, avoiding jamming caused by tilting or deviation.

[0032] The guide bar 34 is located below the opening of the ventilation groove 22. It supports the rod head 311 and prevents the electrostatic dust removal rod 31 from shifting downward due to gravity during sliding, ensuring that the rod head 311 and the inner wall of the through hole 32 always maintain a sealed contact. Especially when the device is tilted or flipped, the guide bar 34 can prevent the rod from accidentally falling off, improving the structural reliability.

[0033] Furthermore, the splash shield 21 is provided with a guide diaphragm 25 inside, and the guide diaphragm 25 is aligned with the side of the vent 22 away from the opening of the splash shield 21. The guide diaphragm 25 is made of elastic material, and the jet pipe 11 passes through the guide diaphragm 25.

[0034] The guide diaphragm 25 is disposed inside the splash shield 21, aligned with the side of the venting slot 22 away from the splash shield opening (i.e., the inner end of the venting slot), and is arranged laterally or obliquely. The jet pipe 11 passes through its center and is fixedly connected to it. It is made of an elastic material (such as silicone, rubber, or elastic plastic), which is deformable, wear-resistant, and resistant to airflow impact, ensuring that it maintains its shape stability under the action of airflow.

[0035] The elastic guide diaphragm 25 tightly wraps around the jet pipe 11, forming a dynamic sealing structure to prevent airflow leakage from the gap between the jet pipe and the splash guard. At the same time, it allows the jet pipe 11 to swing slightly under the action of the elastic connector 26, such as when adjusting the jet angle, while maintaining the sealing performance. When the jet pipe 11 is displaced by external force, the elastic deformation of the guide diaphragm 25 can buffer mechanical stress and avoid component damage caused by hard impact.

[0036] The guide diaphragm 25 blocks the airflow from flowing directly into the ventilation slot 22, forcing the airflow carrying debris to first pass through the concave mold area to complete the purging, and then move along the inner wall of the anti-splash cover 21 towards the ventilation slot 22, ensuring that the debris fully contacts the electrostatic dust removal rod 31 and the filter screen 23, thereby improving the collection efficiency.

[0037] Furthermore, the jet head 12 has a main jet channel 13 and multiple secondary jet channels 14. The main jet passage 13 is positioned along the length of the jet pipe 11 toward the opening of the splash shield 21; Each secondary jet channel 14 is evenly distributed on the jet head 12 along the circumference of the jet head 12, and the jet head 12 is set at an angle.

[0038] The main jet channel 13 outputs a direct airflow that impacts the bottom or center area of ​​the die perpendicularly along the jet pipe axis, generating a high-intensity purging force to remove large areas of accumulated debris such as metal cuttings and larger particles. The secondary jet channel 14 outputs a rotating airflow. Due to the inclined design of the channel, the airflow, ejected at high speed in a circular direction, drives the surrounding air to form a vortex, which moves in a spiral motion along the sidewall of the die, flushing away residual debris on the sidewall and at corners. The multi-directional airflow can replace some manual brushing operations, especially in the cleaning of deep cavity molds, avoiding blind spots caused by limited visibility for the operator.

[0039] Furthermore, an elastic connector 26 is provided between the jet pipe 11 and the splash shield 21 so that the jet pipe 11 and the splash shield 21 can move relative to each other, thereby changing the jet angle of the jet pipe 11 and the jet head 12.

[0040] A flexible connector 26 is disposed between the jet pipe 11 and the splash shield 21, typically located in the middle of the jet pipe or near the root of the splash shield, to achieve a flexible connection between the two. This allows the jet pipe 11 to swing or rotate relative to the splash shield 21 within a certain angular range.

[0041] By changing the relative angle between the jet pipe 11 and the splash shield 21 through external force, such as manual operation or mechanical drive, the airflow direction of the main jet channel 13 and the secondary jet channel 14 of the jet head 12 is changed accordingly. For example, when the die has a deep cavity structure, the jet pipe can be tilted inward into the shield, so that the jet head penetrates into the bottom of the die and enhances the vertical purging force; when cleaning the side wall of the die, the angle of the jet pipe can be adjusted so that the rotating airflow of the secondary jet channel 14 is directly facing the side wall.

[0042] The flexibility of the elastic connector 26 allows the device to adapt to molds of different shapes, such as flat dies, curved dies, and grooves with inclination angles, without the need to replace hardware, thus improving the versatility of the device.

[0043] Furthermore, a handle 27 is provided on the outside of the splash shield 21. The handle 27 is located on the outer wall of the splash shield 21, usually in the middle of the shield or near the opening end, so as to facilitate the operator to grip and apply force.

[0044] When using this device, connect the tail end of the jet pipe 11 to the workshop compressed air pipeline or air pump, ensuring the air valve is open and the airflow pressure is stable. Hold the handle 27 on the outside of the splash shield 21 with one hand, align the opening end of the shield with the surface of the mold cavity, and gently press to make the sealing ring 24 at the edge of the opening fit against the mold, forming a sealed space. Stop applying pressure when you feel slight resistance. Depending on the depth or shape of the cavity, use the other hand to turn the jet pipe 11, adjusting the relative angle between the jet pipe and the splash shield through the elastic connector 26.

[0045] Then, turn on the air source switch, and compressed air enters the jet head 12 through the jet pipe 11, activating the electrostatic dust removal rod 31 to start the cleaning operation.
