High speed precision punch press The influence of stroke on punching, High speed precision punch press has a wide operating stroke range, usually defined in the range of 20 mm to 100 mm. The setting of this specific parameter is closely related to the model specifications and specifications of the punching machine. Specific needs in actual production. The length of the stroke has a direct and significant impact on the precision control and production efficiency during the stamping process. Specifically, although a longer stroke design can give greater flexibility to the stamping process, it may also increase the wear of mold parts, requiring more frequent maintenance or replacement, and increasing operating costs. On the contrary, if the stroke is set more compactly, that is, towards a short stroke, although it can effectively reduce the mold loss, it may limit the depth and shape complexity that the stamping parts can achieve to a certain extent, which will affect the product diversity and design freedom. poses certain challenges. Therefore, when selecting a high speed precision punch press and its stroke parameters, it is necessary to comprehensively consider factors such as production goals, cost-effectiveness, and product quality requirements to achieve the best production balance.
High speed precision punch press The influence of stroke on punching, there is a close relationship between the stroke and pressure of High speed precision punch press. Once the stroke increases, the pressure will increase accordingly; conversely, if the stroke decreases, the pressure will also decrease.
The relationship between High speed precision punch press stroke and pressure is closely related to the material being processed. Generally speaking, the higher the hardness and less plasticity of the metal material, the greater the pressure required, and the stroke will increase accordingly. In addition, the thickness of the material is also one of the important factors affecting pressure and stroke. Thicker materials usually require greater pressure and stroke to complete processing.
The double effect of high speed precision punch press stroke on stamping forming effect
1. Balance of accuracy
In the stamping molding process, the length of the Power strip punch press machine stroke plays a crucial role, which is directly related to the accuracy level of the finished product. Specifically, the use of a moderately short stroke design helps significantly improve the accuracy of the stamping process. This is because the shorter stroke limits the total distance of the punch during movement, thereby reducing the errors that may accumulate due to too long distances, allowing each punch to be closer to the preset accuracy requirements. However, this advantage also comes with potential limitations: too short a stroke may limit the maximum depth and shape complexity that stamping parts can achieve, reducing the adaptability to specific design requirements.
On the contrary, if you choose a longer stroke, although it can cope with more complex and changeable stamping needs and give the product richer morphological changes, it will also increase the risk of errors caused by the long-distance movement of the punch, which may affect the punch. The accuracy of the final product is adversely affected.
2. Efficiency improvements and potential challenges
From the perspective of production efficiency, the length of the High speed precision punch press stroke also has a dual impact. On the one hand, the shorter stroke means that the punch can transition from one stamping cycle to the next more quickly, reducing the overall time required for each stamping, which directly improves overall production efficiency. This is undoubtedly a significant advantage for production environments that pursue efficient output.
But on the other hand, if the stroke is too short to a certain extent, it may cause another efficiency problem: because the amount of processing that can be completed in a single stamping is limited, the frequency of mold replacement may increase. Frequent mold replacement will not only interrupt the continuity of the production process, but may also consume additional time and labor costs due to mold replacement operations, which will ultimately have a negative impact on the overall production efficiency.
3. Correlation with mold life
When the Gantry type high speed stamping machine stroke is set to be longer, the punch needs to move a longer distance in each stamping cycle, which naturally increases the impact force and frequency on the mold contact surface. Over a long period of time, high-intensity impact and frequent friction will accelerate the wear of mold materials, leading to a decrease in mold accuracy and an increase in surface roughness, thereby shortening the overall service life of the mold. Therefore, while pursuing production efficiency, excessively long stroke settings may sacrifice the durability of the mold.
On the contrary, if the high speed precision punch press stroke is shortened reasonably, the movement path of the punch during the stamping process is optimized, and the impact and wear on the mold are reduced accordingly. This design helps maintain the geometric accuracy and surface quality of the mold, thereby extending the service life of the mold and reducing production interruptions and cost increases caused by frequent mold replacement.
However, in some cases, a too short stroke may cause certain local areas of the mold to bear excessive pressure or stress concentration, which in turn accelerates the wear and tear of these areas. damage. Therefore, when setting the high speed precision punch press stroke, it is necessary to comprehensively consider factors such as production efficiency, mold material characteristics, stamping part shape and size requirements, etc., in order to achieve an optimal balance that not only ensures production efficiency but also takes into account mold life.
