Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum connecting piece stamping technology, specifically to a mold structure for preventing material sticking during aluminum material stamping. Background Technology
[0002] In the field of aluminum stamping, especially in the production of precision components such as aluminum connecting pieces for new energy applications, the contact state between the die and the material directly affects product quality and production efficiency. Traditional stamping processes generally rely on stamping oil for lubrication and cooling. By forming an oil film on the contact surface between the die and the aluminum material, friction is reduced, and the heat generated during stamping is carried away, thus alleviating the problem of material sticking. However, this process has a significant drawback: the strong adhesion of stamping oil results in a large amount of oil residue remaining on the surface of the stamped aluminum products, necessitating an additional cleaning process to remove the oil.
[0003] The cleaning process not only requires additional costs for cleaning agents and equipment, but also involves cumbersome operations and long processing times. More importantly, the cleaning process is prone to surface damage and dimensional deviations due to cleaning agent residue and uneven cleaning intensity, significantly increasing the product defect rate. Simultaneously, the continuous consumption of stamping oil and the cost of waste liquid treatment further burden the company's production. When stamping speeds increase or processing precision requirements rise, the cooling and lubrication efficiency of the stamping oil becomes difficult to match, easily leading to material sticking due to localized overheating, and even equipment failures such as punch breakage, severely impacting production continuity and mold lifespan. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a mold structure for preventing material sticking during aluminum stamping, thereby solving the technical problems of high cleaning costs, high defect rates, and material sticking and mold damage caused by traditional stamping oil in the field of aluminum connecting piece stamping technology.
[0005] To achieve the above-mentioned technical objectives, the present invention provides a mold structure for preventing material sticking during aluminum stamping, including... An upper pad with an alcohol flow channel on its upper surface; the alcohol flow channel includes a main alcohol channel and branch alcohol channels; one end of each of the multiple branch alcohol channels is connected to the main alcohol channel; the multiple branch alcohol channels are distributed on both sides of the main alcohol channel; a first alcohol hole is provided at the end of each of the multiple branch alcohol channels away from the main alcohol channel; the first alcohol hole penetrates the upper and lower surfaces of the upper pad; the starting end of the main alcohol channel is located on one side of the upper pad; the starting end of the main alcohol channel is threaded for connecting to an alcohol tube quick connector.
[0006] Compared with the prior art, the beneficial effects of this utility model include: 1. Highly efficient anti-sticking and mold protection: This invention, based on the structural design of the second alcohol hole in the punch, the alcohol flow channel in the upper backing plate, and the first alcohol hole, constructs a stable alcohol delivery channel. During stamping, the alcohol can flow precisely from the alcohol reservoir → alcohol pipe → alcohol flow channel → second alcohol hole to the stamping contact surface. The rapid evaporation and cooling properties of the alcohol can instantly remove the heat generated during stamping, fundamentally avoiding the problem of aluminum material sticking to the mold due to local overheating. At the same time, it reduces frictional wear between the punch and the aluminum material, effectively reducing the risk of punch breakage and significantly extending the service life of the mold.
[0007] 2. Streamlined Processes and Reduced Costs: Utilizing the core technology of replacing traditional stamping oil with alcohol, the alcohol evaporates quickly and naturally after stamping, leaving no residue and completely eliminating the necessary product cleaning step in traditional processes. This technological improvement not only avoids the procurement costs of cleaning agents and equipment, as well as waste liquid treatment costs, but also solves problems such as product damage and dimensional deviations caused by improper operation during the cleaning process, reducing the product defect rate. Furthermore, the procurement cost of alcohol is lower than that of stamping oil, and the conveying structure does not require complex power units, further reducing production consumables and energy costs, and improving the company's economic efficiency.
[0008] 3. High adaptability and convenient operation: Based on a modular mold assembly structure (the upper mold base, upper pad, upper clamping plate, etc. are fixed with screws, and the alcohol bottle is connected to the mold via an alcohol tube quick connector), this structure can be flexibly adapted to stamping scenarios for new energy aluminum connecting plates and various aluminum materials. The alcohol delivery system can be controlled by a valve on the side of the alcohol bottle, making operation simple and quick. It requires no large-scale modification of existing stamping equipment, facilitating rapid promotion and application by enterprises, and effectively improving production efficiency and process adaptability.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0012] Please see Figure 1 , Figure 2 , Figure 3 This embodiment provides a mold structure for preventing material sticking during aluminum stamping, including an upper backing plate 1, an upper mold base 6, an upper clamping plate 7, a stripper backing plate 8, a stripper plate 9, a lower template 101, a lower backing plate 102, a lower mold base 103, a punch 2, an alcohol bottle 5, an alcohol tube 4, and an alcohol tube quick connector 3.
[0013] Furthermore, the upper pad 1 is provided with an alcohol flow channel 11, which includes a main alcohol flow channel 111 and branch alcohol flow channels 112. One end of each of the multiple branch alcohol flow channels 112 is connected to the main alcohol flow channel 111, and the multiple branch alcohol flow channels 112 are distributed on both sides of the main alcohol flow channel 111.
[0014] Furthermore, the number of alcohol branch channels 112 depends on the number of punches 2, specifically on the shape of the aluminum product structure. At the same time, the width and depth of the main alcohol channel 111 and the alcohol branch channels 112 also depend on the shape and structure of the aluminum product, and the specific structural dimensions are designed as needed.
[0015] Furthermore, in this embodiment, the main alcohol channel 111 is 4.0 mm wide and 3.0 mm deep.
[0016] Furthermore, each of the multiple alcohol branch channels 112 has a first alcohol hole 113 at one end away from the main alcohol channel 111. The first alcohol hole 113 penetrates the upper and lower surfaces of the upper pad 1, ensuring that the alcohol in the alcohol channel 11 can flow to the punch through the first alcohol hole 113.
[0017] Furthermore, the diameters of the first alcohol hole 113 and the second alcohol hole 21 are designed according to specific circumstances, but usually the diameter of the first alcohol hole 113 is twice that of the second alcohol hole 21.
[0018] Furthermore, the starting end of the main alcohol channel 111 is located on one side of the upper pad 1, and the starting end of the main alcohol channel 111 is threaded for connecting the quick-connect alcohol tube 3. Specifically, when the quick-connect alcohol tube 3 is threaded to the upper pad 1, multiple turns of sealing tape are wrapped around it to ensure the sealing of the connection between the two.
[0019] Furthermore, one end of the alcohol tube quick connector 3 is connected to an alcohol tube 4, and the other end of the alcohol tube 4 is connected to an alcohol bottle 5. The horizontal plane of the alcohol bottle 5 is higher than the horizontal plane of the upper pad 1. Under the action of gravity, the alcohol in the alcohol bottle 5 can flow naturally along the alcohol tube 4 to the alcohol flow channel 11 of the lower upper pad 1, and then enter the first alcohol hole 113.
[0020] Furthermore, the alcohol reservoir 5 is filled with alcohol and fixed to the punch press. Two alcohol channels 11 are opened on the upper surface of the upper pad 1. The alcohol reservoir 5 is provided on both sides of the upper pad 1 to provide sufficient alcohol to the punch 2 and avoid alcohol shortage, which would cause the stamped product to be scrapped.
[0021] Furthermore, the upper surface and lower surface of the upper pad plate 1 are respectively provided with an upper mold base 6 and an upper clamping plate 7. The upper clamping plate 7 is equipped with the punch 2 through a through hole. The punch 2 has a second alcohol hole 21 that runs through the upper and lower parts. The second alcohol hole 21 is used to allow the alcohol in the alcohol branch channel 112 to flow through the punch 2 to the surface of the aluminum material.
[0022] Furthermore, when installing the punch 2, firstly, the punch 2 is inserted into the upper clamping plate 7, and then the upper clamping plate 7, the upper pad plate 1, and the upper mold base 6 are fixed with screws.
[0023] Furthermore, the first alcohol hole 113 and the second alcohol hole 21 are coaxially arranged with their centers coinciding. The number of punches 2 corresponds to the number of the first alcohol holes 113, ensuring that the alcohol in each of the first alcohol holes 113 can flow to the surface of the aluminum material.
[0024] Specifically, during the stamping process, the valve 51 on the side of the alcohol reservoir 5 is opened, allowing the alcohol in the reservoir 5 to flow into the alcohol flow channel 11 through the alcohol pipe 4. The alcohol then flows through the main alcohol channel 111 and the branch alcohol channels 112 into the first alcohol hole 113, and then through the second alcohol hole 21 of the punch 2 to the surface of the aluminum material. This serves to cool the punch during stamping, replacing traditional stamping oil. This method eliminates the need for mold cleaning after stamping, resulting in low cost and high efficiency. Furthermore, the rapid evaporation and cooling properties of alcohol instantly remove the heat generated during stamping, preventing aluminum material from sticking to the mold due to localized overheating, reducing frictional wear between the punch 2 and the aluminum material, effectively lowering the risk of punch breakage, and significantly extending the mold's lifespan. The alcohol evaporates quickly and naturally after stamping, leaving no residue, completely eliminating the product cleaning process required in traditional processes.
[0025] Furthermore, the lower surface of the upper clamping plate 7 is sequentially provided with a stripping back plate 8 and a stripping plate 9. The stripping back plate 8 and the stripping plate 9 are bolted together. The stripping back plate 8 and the stripping plate 9 are fixedly connected to the upper clamping plate 7 through guide posts 10 and elastic elements.
[0026] Furthermore, the mold also includes a lower template 101, a lower backing plate 102, and a lower mold base 103.
[0027] Furthermore, the lower template 101, the lower pad 102, and the lower mold base 103 are sequentially bolted together, and a lower pad block 104 is provided at the bottom of the lower mold base 103 to support the lower mold base 103.
[0028] Working principle: The mold structure for preventing material sticking during aluminum stamping provided by this utility model includes an upper pad 1 with an alcohol flow channel 11 on its upper surface. The alcohol flow channel 11 includes a main alcohol channel 111 and branch alcohol channels 112. One end of each branch alcohol channel 112 is connected to the main alcohol channel 111. The branch alcohol channels 112 are distributed on both sides of the main alcohol channel 111. A first alcohol hole 113 is provided at the end of each branch alcohol channel 111 away from the main alcohol channel 112. The first alcohol hole 113 penetrates the upper and lower surfaces of the upper pad 1. The starting end of the main alcohol channel 111 is located on one side of the upper pad 1. The starting end of the main alcohol channel 111 is threaded for connecting an alcohol tube quick connector 3.
[0029] Specifically, during the stamping process, the valve 51 on the side of the alcohol reservoir 5 is opened, allowing the alcohol in the reservoir 5 to flow into the alcohol flow channel 11 through the alcohol pipe 4. The alcohol then flows through the main alcohol channel 111 and the branch alcohol channel 112 into the first alcohol hole 113, and then through the second alcohol hole 21 of the punch 2 to the surface of the aluminum material. This alcohol cools the punch during stamping, replacing traditional stamping oil. This method eliminates the need for mold cleaning after stamping, resulting in low cost and high efficiency. Simultaneously, the rapid volatility and cooling properties of alcohol instantly remove the heat generated during stamping, preventing aluminum material from sticking to the mold due to localized overheating. It also reduces frictional wear between the punch and the aluminum material, effectively lowering the risk of punch breakage and significantly extending the mold's service life.
