3. Scientific Selection Guide for Antishi Hydraulic Punching Machines (Core Science Communication + Practical Recommendations)
The core principle of selecting a hydraulic punching machine is “matching requirements while balancing efficiency and cost.” Many companies face issues such as equipment overload, insufficient processing accuracy, and wasted capacity due to improper selection. Based on Antishi’s product characteristics and industry experience, a scientific selection plan is provided below from five core dimensions to help companies precisely match equipment and avoid selection pitfalls.
(1) Core Selection Dimension 1: Define Processing Requirements (Fundamental Prerequisite)
Before selection, three core requirements must be clarified to avoid blind decision-making:
-
Material and Thickness: Identify the metal sheet material (cold-rolled sheet, stainless steel sheet, etc.) and thickness. Antishi hydraulic punching machines are conventionally suitable for thin to medium sheets of 0.5mm–6mm, with some models capable of processing 6–8mm low-carbon steel sheets. Note that high-hardness materials (e.g., quenched steel sheets) or sheets exceeding the equipment’s maximum thickness are unsuitable for conventional hydraulic punching machines; customized solutions can be arranged by contacting Antishi.
-
Processing Technology and Precision: Clarify the core processing operations (punching, blanking, forming, drawing, etc.). If high-precision processing is required (e.g., for electrical enclosures or automotive parts), prioritize Antishi’s high-precision models to ensure hole position accuracy and forming quality. For general hardware processing, more cost-effective standard models can be chosen.
-
Production Capacity Requirements: Determine the required stroke rate and automation needs based on daily processing volume. The Antishi JC21 series offers a stroke rate of 45–60 times per minute. For high-volume production, automatic feeding devices can be added to achieve fully automated production and increase capacity.
(2) Core Selection Dimension 2: Tonnage Selection (Critical Parameter)
Tonnage is a core parameter of a hydraulic punching machine, representing the maximum pressure the slide can apply and directly determining processing capability. Selection must follow the principle of “precise calculation with reserved margin” to avoid insufficient tonnage or waste:
-
Tonnage Calculation Method: Refer to the stamping force calculation formula: P = T × L × K (where P = stamping force, T = material thickness in mm, L = stamping perimeter in mm, K = material shear strength in N/mm²). Additionally, consider the material holding force (approximately 30% of the stamping force). Forming processes require additional calculation of forming force.
-
Antishi Tonnage Selection Recommendations: Match tonnage reasonably based on processing requirements, reserving a 20% safety margin to avoid equipment overload and die damage. Specific recommendations are as follows:
-
Small-scale processing (thin sheets, small hole diameters): Choose JC21-25T (nominal force 250 kN) or JC21-40T (nominal force 400 kN). Suitable for processing small appliance parts and small hardware components.
-
Medium-scale processing (medium-thickness sheets, conventional hole shapes): Choose JC21-63T (nominal force 630 kN) or JC21-80T (nominal force 800 kN). Suitable for processing electrical enclosures, automotive parts, and architectural decorative panels.
-
Large-scale processing (thicker sheets, complex forming): Choose JC21-100T (nominal force 1000 kN). Suitable for processing agricultural machinery and construction machinery components.
-
(3) Core Selection Dimension 3: Equipment Parameter Matching (Detailed Key Points)
Beyond tonnage, parameters such as slide stroke, die height, and worktable dimensions of Antishi hydraulic punching machines must be precisely matched to the workpiece and die dimensions:
-
Slide Stroke: The distance from the slide’s top dead center to bottom dead center. It should be greater than twice the height of the stamped part to ensure smooth loading of the blank and removal of the finished part. The Antishi JC21 series offers slide strokes ranging from 80 mm to 130 mm, accommodating workpieces of different heights.
-
Die Height: The distance (adjustable) between the slide at bottom dead center and the worktable surface. It must match the die’s closed height to ensure normal operation after die installation. Antishi hydraulic punching machines offer die height adjustment ranges from 45 mm to 100 mm, providing flexible adjustment for different die specifications.
-
Worktable Dimensions: Must be larger than the horizontal dimensions of the lower die, with 50–70 mm reserved on each side for die installation. Antishi worktable dimensions range from 400×600 mm to 500×900 mm, accommodating workpieces of various sizes and meeting processing needs from small to large scales.
