How to choose a good high-speed precision punch

With the development and progress of science and technology, based on the requirements of product quality and productivity, high-speed punch is more and more widely used in stamping industry. Especially in industries such as precision mobile phones, computer components, LED brackets, IC frames and motors, high-speed punching machines are needed. So how to choose high-speed punching machine correctly?

I. Selection of Model and Tonnage

According to the precision, size and mold requirements of the product, you can choose to use C-type or gantry type high-speed punch or elbow type high-speed punch, and how many tons are needed: C-type from 15, 25, 30, 35, 40, 45, 50, 60, 65, 80,11. H-type gantry crane can be selected from 30, 35, 45, 60, 65, 80 and 85 tons.

Second, the stroke and mold height and adjustment

According to the product shape, bending height and supporting mold, the stroke height and mold height can be selected. The stroke height is selected from 13, 15, 20, 25, 30, 35, 40 and 50MM, and the adjustment amount is generally 30 and 40 mm..

Third, the scale of the platform

Generally, the tonnage selected is the relative platform size, which is slightly different from different manufacturers.

Four, feeder model, specification selection

According to the product material and feeding speed, roller feeder, numerical control feeder, gear feeder and clip feeder can be selected. Generally, roller feeders are used, gear feeders are generally used for stamping the stator and rotor of the motor, and numerical control feeders are digitally adjusted, which is convenient and fast, and the cost performance is higher below 200SPM. The clip feeder is used for thinner stamping materials. Then choose different specifications according to the width of the product material, such as 105: feeding width 100MM, length 50 mm.

Verb (abbreviation of verb) brand choice

According to the types of enterprises and customers, you can choose imported brands or imported brands assembled in China, Taiwan Province brands and domestic brands. Foreign brands are: Brudre Bruwood, Switzerland, Jingrui, Dobby Yamada, Dobby Yamada, Li Zhen and Gao Jiang, Taiwan Province Province, etc. And domestic brands such as Mingxun, Taiji Mountain and Hong Rui.

Six, the accuracy requirements

Precision is the standard to judge the quality of high-speed punch, so precision requirement is the key to choose a good punch. Test from the following four aspects: (1) parallelism; (2) verticality; (3) Full customs clearance; (4) Repetition accuracy of dynamic bottom dead center. Although the current precision value can be qualified, the long-term stability can be distinguished from the materials and processing technology of cast iron, crankshaft, bearing, copper sleeve and other parts used in the punch.

Seven, cost performance

The quality of foreign brands of punching machines is indeed better. From the material of the machinery itself, after decades of running-in correction, the stability is extremely high and the failure rate is very few. That is, the price is expensive, the delivery time is long, and the after-sales price is expensive.

Domestic punch is becoming more and more mature and stable, and the price is also affordable. Low after-sales and accessories, low maintenance costs. But there are many brands on the market at present, and there are even some patchwork assembly machines. It is recommended to know more about it and make a field trip when buying. Avoid buying 1, inferior cast iron material: trachoma, stress deformation, 2, irregular processing of accessories, wear after long-term use.

Hong Rui Punch Machine is a listed company in China New Third Board, with standardized scale, production and operation. Product types are complete: pneumatic punch, C-type high-speed punch, gantry high-speed punch, elbow-bar punch, pull-down high-speed punch and automatic production line. In particular, the precision and stability of elbow precision punch can be comparable to that of Japanese brand punch, and all accessories adopt traceability and coding system. While continuously improving quality, the company also attaches great importance to after-sales service to create higher value for customers.

Welcome to call to discuss specific matters. I have been engaged in the stamping industry for more than ten years, and I have different resources in the LED industry, IC frame industry and connector industry, from material suppliers, molds, equipment, electroplating and other front-end, middle-end and back-end processing, injection molding, molding and other automation equipment and production processes, so I can share resources and win-win cooperation!
