Things to note when buying a high speed precision punch press, a comprehensive guide to efficiently purchasing a high-speed precision punch press
With the surging wave of science and technology, the pursuit of production efficiency and product quality in the manufacturing industry has reached an unprecedented height. As a leader in stamping technology, high-speed precision punch press has been widely used in key areas such as precision electronic products (such as smart phones, computer parts), LED lighting equipment brackets, integrated circuit (IC) packaging frames, and precision motors. In order to ensure the efficient operation of your production line, it is crucial to correctly choose a suitable high-speed precision punch press. How to buy a high-speed precision punch press, the following is a detailed purchase guide:
1. Accurate positioning, choose the appropriate model and tonnage
Model selection: Faced with a variety of high-speed precision punch press models, such as C-type and gantry type (or H-type), the selection should be closely combined with production practice. The C-type high-speed precision punch press has a compact structure and is suitable for stamping small and medium-sized parts and high-precision products; while the gantry type high-speed precision punch press is better at handling large workpieces or scenes requiring high load capacity with its strong rigidity and stability.
Tonnage matching: The choice of tonnage is directly related to the processing capacity and scope of application of the high-speed precision punch press. According to the material, thickness, shape complexity and mold design of the product, the required punching force is accurately calculated to select the appropriate tonnage. The C-type high speed precision punch press provides a wide range of tonnage, ranging from 15 tons to 120 tons, which is enough to meet most precision processing needs; while the gantry type high speed precision punch press usually covers the range of 30 tons to 85 tons, which is designed for large or heavy workpieces.
2. Stroke, mold height and adjustment range setting
For the specific shape of the product and the required bending height, we carefully match the mold and determine the appropriate stroke height accordingly. The stroke height selection range is wide, covering multiple standard options from 13MM to 50MM (specifically 13, 15, 20, 25, 30, 35, 40, 50MM) to meet different production needs. In addition, in order to adapt to subtle adjustment needs, we usually reserve 30MM to 40MM adjustment to ensure processing accuracy and flexibility.
3. Basis for selecting platform size
The selection of platform size is often closely related to the tonnage of the selected stamping machine, and different manufacturers may provide slightly different platform specifications. Therefore, when selecting the platform size, it is necessary to comprehensively consider the equipment tonnage and actual production needs to ensure that the platform can not only meet the current production needs, but also have a certain degree of scalability.
4. Accurate selection of feeder types and specifications
The selection of feeders needs to be closely combined with factors such as product material characteristics, desired feeding speed, and processing accuracy. Common feeder types include roller feeders, NC feeders, gear feeders, and clamp feeders, each of which has its own unique application scenarios.
- Roller feeder: As a more versatile choice, it is widely used in feeding operations of various materials and is favored for its stable and reliable performance.
- Gear feeder: Especially suitable for occasions with extremely high requirements for feeding accuracy, such as the stamping production of motor stators and rotors, which can ensure the accuracy of each feeding.
- NC feeder: It adopts advanced digital adjustment technology, is easy and fast to operate, and is especially suitable for use in production environments where the speed does not exceed 200SPM. It has significant cost-effectiveness.
- Clamp feeder: It is designed for processing thinner stamping materials. Its unique clamping method effectively prevents the material from shifting or deforming during the feeding process.
In addition, after determining the type of feeder, it is necessary to select the appropriate specification according to the actual width of the product material. For example, if the width of the product material is 100MM, you can choose a feeder with a feeding width of 100MM (such as the specification marked as 105, where 5MM may be a safety margin or adjustment space) and a length of 50MM to ensure the accuracy and efficiency of feeding.
5. Brand selection
According to the type of enterprise and customer object, you can choose imported brands or domestically assembled imported brands, Taiwanese brands, and domestic brands. Foreign brands include: BRUDERER of Switzerland, KYORI of Japan, YAMADA DOBBY, Zhenli, Gaojiang of Taiwan, etc. Domestic brands include Mingxun, Taijishan, Hongrui, etc.
6. Accuracy requirements
Accuracy is the detection and judgment standard of the quality of high-speed precision punch press, so the accuracy requirement is the key to choosing a good high-speed precision punch press. It is tested from the following four aspects: ⑴ Parallelism ⑵ Verticality ⑶ Comprehensive clearance ⑷ Dynamic bottom dead point repeatability. Although the current accuracy values can be qualified, the long-term stability can be distinguished from the materials and processing technology of the high-speed precision punch press, such as cast iron, crankshaft, processing technology, bearings, copper sleeves and other accessories.
7. Value considerations and cost-effectiveness analysis
When it comes to high-speed precision punch presses of foreign brands, their excellent quality is undoubtedly a recognized highlight in the industry. These high-speed precision punch presses not only use higher-quality materials in mechanical structure to ensure the durability and accuracy of the equipment, but also have accumulated rich experience and data support after decades of continuous technical iteration and performance optimization. Therefore, they show extremely high operating stability and extremely low failure rate, which is undoubtedly an attractive advantage for enterprises pursuing efficient and stable production environment.
However, just like the two sides of a coin, foreign brands of high speed precision punch press bring high quality but also come with a relatively high price tag. This is mainly due to the combined effect of factors such as their R&D investment, brand premium and import tariffs. In addition, since the production site is usually far away from the domestic market, the delivery cycle is relatively long, which may bring certain time cost pressure to enterprises that urgently need equipment to put into production. Moreover, although the after-sales service is professional, the cost is also high. While enjoying high-quality services, enterprises also need to consider this additional expenditure.
Therefore, when evaluating the cost-effectiveness of foreign brands of high speed precision punch press, enterprises need to consider many factors comprehensively: if you pursue the ultimate quality stability and long-term production benefits, and have sufficient budget, then these high-end high speed precision punch press are undoubtedly the ideal choice; if you have high requirements for cost control or are more sensitive to time costs, you may need to weigh the pros and cons and consider whether to choose domestic brands or other alternatives with higher cost-effectiveness and faster delivery. Ultimately, the choice of high speed precision punch press should be based on the company's actual needs, budget and market strategy.
