Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a toothed stamping mold with multiple drainage grooves. Background Technology

[0002] In the field of metal stamping, stamping dies are key tools used to process raw materials such as metal sheets into parts of specific shapes and sizes through stamping processes. In the stamping production of products such as metal teeth, the effective utilization and rational allocation of materials are crucial for reducing production costs and improving production efficiency.

[0003] Currently, in common iron tooth stamping dies, during the stamping process, when the upper die's punch and the lower die's die press against each other to shape the material to be stamped into the desired form, excess material will accumulate in specific areas such as the protrusions of the iron teeth due to the flow and accumulation of material during the stamping deformation process. If this excess material is not handled in a timely and effective manner, it will not only cause material waste and increase production costs, but the accumulation of excess material in the die may also affect the smooth progress of subsequent stamping processes, leading to quality defects in the stamped products, such as burrs, flash, and dimensional deviations, thus reducing the product qualification rate. Utility Model Content

[0004] The purpose of this invention is to provide a tooth stamping die with multiple drainage grooves to solve the problem mentioned in the background art: in the current common tooth stamping die, during the stamping process, when the upper die punch and the lower die die press against each other to form the material to be stamped into the required shape, excess material will be generated in specific areas such as the protrusions of the tooth due to the flow and accumulation of the material during the stamping deformation process.

[0005] To achieve the above objectives, this utility model provides a toothed stamping die with multiple drainage grooves, including a base, side plates installed on both sides of the top of the base, an upper die and a lower die arranged between the side plates, a punch installed at the bottom of the upper die, and a die provided at the top of the lower die. The material to be stamped is pre-placed on the die, and the upper die presses downward, causing the punch and die to press together, so that the material to be stamped on the die is stamped and formed. The inside of the die is provided with a groove, and the outside of the groove is provided with multiple drainage grooves.

[0006] Preferably, guide components are installed on the bottom of both sides of the fixing frame. The guide components include guide rods and guide sleeves, which are inserted and fitted together. The upper end of the guide rod is fixed on the fixing frame, and the lower end of the guide sleeve is fixed on the upper mold.

[0007] Preferably, a fixing frame is installed between the tops of the side plates, a drive cylinder is installed on the top of the fixing frame, a stamping rod is installed on the bottom output shaft of the drive cylinder, the bottom end of the stamping rod is connected and fixed to the upper die, and the lower die is fixed on the base.

[0008] Preferably, the bottom of the punch is provided with toothed protrusions that are adapted to the shape of the groove.

[0009] Preferably, the drainage channel includes a first drainage channel away from the center of the die cavity and a second drainage channel near the center of the die cavity.

[0010] Preferably, the first and second drainage channels are evenly inclined, and the opening angle of the first drainage channel is greater than the opening angle of the second drainage channel.

[0011] Preferably, the bottom surfaces of both the first and second drainage channels are provided with a wear-resistant coating, which is made of tungsten carbide and has a thickness of 0.1-0.3 mm.

[0012] Preferably, the bottom of the base is provided with shock-absorbing pads made of rubber material, and the bottom of the shock-absorbing pads is provided with anti-slip texture to increase the friction between the mold and the placement surface, and at the same time reduce the vibration generated by the mold during operation.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this multi-channel stamping die for iron teeth, the die cavity of this invention has multiple channeling channels on the outer side of the groove, including a first channeling channel away from the center of the die cavity and a second channeling channel close to the center of the die cavity. During the stamping process, excess material at positions such as the protruding parts of the iron teeth can be effectively channeled to the sides and other effective positions, greatly reducing material waste. The rationally designed channeling channels can guide the orderly flow of excess material, avoiding large accumulation of material in key areas such as protrusions. This helps to ensure uniform deformation of the material during the stamping process, resulting in a smoother surface of the stamped iron teeth product and reducing the generation of quality defects such as burrs and flash.

[0015] The bottom surfaces of both the first and second drainage channels are coated with a wear-resistant coating made of tungsten carbide with a thickness of 0.1-0.3 mm. Tungsten carbide has extremely high hardness and wear resistance, which can effectively resist the wear of the drainage channels by the material during the stamping process and extend the service life of the drainage channels.

[0016] The guide assemblies installed at the bottom of both sides of the fixed frame consist of guide rods and guide sleeves that fit together. The upper end of the guide rod is fixed to the fixed frame, and the lower end of the guide sleeve is fixed to the upper die. During the stamping process, the guide assemblies provide precise guidance for the movement of the upper die, ensuring that the upper die moves smoothly and accurately downwards to press against the lower die. This prevents the upper die from shifting or wobbling during movement, ensuring the stability and accuracy of the stamping process and further improving product quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a stamping die with multiple drainage grooves, such as... Figures 1-3 As shown, the device includes a base 1, with side plates 3 mounted on both sides of the top of the base 1. An upper mold 8 and a lower mold 7 are disposed between the side plates 3. A punch 81 is mounted on the bottom of the upper mold 8, and a die 71 is disposed on the top of the lower mold 7. The material to be stamped is pre-placed on the die 71. The upper mold 8 presses downward, causing the punch 81 to press against the die 71, thus forming the material to be stamped on the die 71. A groove 72 is provided inside the die 71, and multiple drainage grooves are provided on the outside of the groove 72. In this invention, multiple drainage grooves are provided on the outside of the groove 72 of the die 71. When the upper mold 8 drives the punch 81 to press downward and press against the die 71, excess material in areas such as the protruding iron teeth can be effectively drained to the sides or other effective positions.

[0024] The toothed protrusions 82 at the bottom of the punch 81 are perfectly matched with the grooves 72 of the die 71 to ensure uniform material deformation during the stamping process.

[0025] The flow channels are divided into a first flow channel 73 located away from the center of the die 71 and a second flow channel 74 located closer to the center. The opening angle of the first flow channel 73 is larger than that of the second flow channel 74, forming a graded flow channel structure, which makes the material flow more smoothly, avoids local stress concentration, and further reduces the risk of product deformation and cracking.

[0026] In this embodiment, guide components 4 are installed on the bottom of both sides of the fixed frame 2. The guide components 4 include guide rods and guide sleeves, which are inserted and fitted together. The upper end of the guide rod is fixed to the fixed frame 2, and the lower end of the guide sleeve is fixed to the upper die 8. During the stamping process, the guide components provide precise guidance for the up and down movement of the upper die 8, ensuring that the movement trajectory of the upper die 8 is stable and vertical, reducing stamping offset, and ensuring that the punch 81 and the die 71 are accurately pressed together, thereby improving stamping accuracy.

[0027] Specifically, a fixing bracket 2 is installed between the tops of the side plates 3, a drive cylinder 5 is installed on the top of the fixing bracket 2, and a stamping rod 6 is installed on the bottom output shaft of the drive cylinder 5. The bottom end of the stamping rod 6 is connected and fixed to the upper die 8, and the lower die 7 is fixed on the base 1. The drive cylinder 5 provides stable and strong stamping power to the upper die 8 through the stamping rod 6, ensuring that the stamping process is fast and powerful.

[0028] Furthermore, a toothed protrusion 82 is installed on the bottom of the punch 81, and the shape of the toothed protrusion 82 is adapted to the groove 72. The precise fit between the toothed protrusion 82 and the groove 72 ensures that the material to be stamped is uniformly deformed during the stamping process, forming a toothed shape that meets the design requirements.

[0029] Furthermore, the guide channels include a first guide channel 73 located away from the center of the die 71 and a second guide channel 74 located near the center of the die 71. By setting guide channels at different positions, excess material can be guided more effectively during stamping, reducing material accumulation in critical areas such as protrusions.

[0030] Furthermore, the first flow channel 73 and the second flow channel 74 are evenly inclined, and the opening angle of the first flow channel 73 is greater than the opening angle of the second flow channel 74. The different opening angles make the material flow smoother and more orderly, avoid material blockage in the flow channel, further optimize material distribution, and reduce problems such as deformation and cracking of the product caused by material accumulation.

[0031] Furthermore, both the bottom surfaces of the first and second drainage channels 73 and 74 are coated with a wear-resistant coating made of tungsten carbide, with a thickness of 0.1-0.3 mm. The tungsten carbide wear-resistant coating possesses high hardness and wear resistance, effectively resisting material wear on the drainage channels during the stamping process and extending the service life of the drainage channels.

[0032] Furthermore, the bottom of the base 1 is equipped with shock-absorbing pads 9. These pads 9 are made of rubber and have anti-slip textures on their bottom to increase friction between the mold and the placement surface, thereby reducing vibrations generated during mold operation. The rubber shock-absorbing pads 9 absorb and cushion vibrations generated during mold operation, reducing the impact of vibrations on the mold itself and surrounding equipment, extending the mold's service life. Simultaneously, the anti-slip textures increase friction between the mold and the placement surface, preventing mold slippage and ensuring stability during the stamping process.

[0033] When using the iron tooth stamping die with multiple drainage grooves of this utility model, the material to be stamped is first placed on the die cavity 71 to ensure accurate material positioning and prepare for subsequent stamping. The drive cylinder 5 is then activated to put it in standby mode, ready to provide power for the stamping process.

[0034] The drive cylinder 5 is activated, and its bottom output shaft drives the stamping rod 6 to move downwards. Since the bottom end of the stamping rod 6 is fixedly connected to the upper die 8, the upper die 8 moves downwards accordingly. During the downward movement of the upper die 8, the guide components 4 on both sides of the bottom of the fixed frame 2 function. The guide rod and guide sleeve are interlocked; the upper end of the guide rod is fixed to the fixed frame 2, and the bottom end of the guide sleeve is fixed to the upper die 8, providing precise guidance for the up-and-down movement of the upper die 8, ensuring a stable and vertical movement trajectory, reducing stamping offset, and allowing the punch 81 to accurately press against the die 71. The upper die 8 continues to move downwards, and the toothed protrusion 82 at the bottom of the punch 81 presses against the groove 72 of the die 71. Because the shape and height of the toothed protrusion 82 and the groove 72 are perfectly matched, the material to be stamped deforms uniformly during the stamping process, forming a toothed shape that meets the design requirements.

[0035] During the stamping process, excess material is generated in areas such as the protruding iron teeth. At this time, multiple drainage channels provided on the outer side of the groove 72 of the die 71 come into play. The drainage channels are divided into a first drainage channel 73 far from the center of the die 71 and a second drainage channel 74 closer to the center, with the opening angle of the first drainage channel 73 being larger than that of the second drainage channel 74, forming a graded drainage structure. Under the action of the graded drainage structure, the excess material flows more smoothly to the sides or other effective positions, avoiding local stress concentration and reducing the risk of product deformation and cracking.

[0036] The first and second flow channels 73 and 74 are evenly inclined, and their different opening angles make the material flow more orderly. The material flows along a preset path within the channels, avoiding blockages, further optimizing material distribution, and reducing deformation and cracking caused by material accumulation. Both the bottom surfaces of the first and second flow channels 73 and 74 are coated with a wear-resistant coating made of tungsten carbide with a thickness of 0.1-0.3 mm. The tungsten carbide wear-resistant coating has high hardness and wear resistance, effectively resisting material wear during stamping, extending the service life of the channels, and ensuring good flow control throughout repeated stamping processes.

[0037] After stamping is completed, the drive cylinder 5 drives the stamping rod 6 to move upward, and the upper die 8 rises accordingly, separating the punch 81 from the die 71. The stamped iron tooth product is then removed, and the product quality is checked to ensure it meets the requirements.

[0038] Finally, it should be noted that the electronic components in the drive cylinder 5 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order of each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
