床刀/压力辊

Bed knife and pressure roller assembly for fleshing machines that removes flesh and fat from animal hides during leather production.

技术定义与适配语境
典型 床刀/压力辊 会按材料、尺寸公差、适配关系和失效风险在 皮革及相关产品制造 中评估。

A critical dual-component assembly in fleshing machines consisting of a stationary bed knife and a rotating pressure roller. The bed knife provides a sharp cutting edge while the pressure roller applies controlled pressure to feed hides against the blade, enabling precise removal of subcutaneous tissue, fat, and residual flesh from the flesh side of animal hides during the beamhouse stage of leather processing.

定义
A critical dual-component assembly in fleshing machines consisting of a stationary bed knife and a rotating pressure roller. The bed knife provides a sharp cutting edge while the pressure roller applies controlled pressure to feed hides against the blade, enabling precise removal of subcutaneous tissue, fat, and residual flesh from the flesh side of animal hides during the beamhouse stage of leather processing.
工作原理
The pressure roller rotates against the stationary bed knife, creating a shearing action that slices through flesh and fat layers as hides are fed through the gap. The adjustable pressure and gap settings allow for controlled material removal without damaging the grain layer of the hide.
材料
Bed knife: High-carbon tool steel (AISI D2AISI O1) or tungsten carbide with hardness 58-62 HRC. Pressure roller: Chromium-plated hardened steel or ceramic-coated steel with surface hardness 55-60 HRC. Both components feature corrosion-resistant coatings for wet processing environments.
Bed Knife Length
1200-3000 mm
Power Requirement
5.5-15 kW
Maximum Feed Speed
15-30 m/min
Operating Pressure
2-8 bar
Gap Adjustment Range
0.1-5.0 mm
Pressure Roller Diameter
150-250 mm
标准
ISO 15115DIN 53301ISO 2418

常见问题

What is the purpose of the bed knife and pressure roller in fleshing machines?

The bed knife provides a stationary cutting edge while the pressure roller applies controlled pressure to feed hides against the blade, enabling precise removal of flesh, fat, and subcutaneous tissue from animal hides during leather processing.

How often should bed knives be sharpened or replaced?

Bed knives typically require sharpening every 40-80 operating hours and replacement every 6-12 months depending on usage intensity, material hardness, and maintenance practices. Regular inspection for nicks, wear patterns, and edge deterioration is recommended.

What materials are best for bed knives in high-production environments?

Tungsten carbide or ceramic-coated high-carbon steel blades offer superior wear resistance and longer service life in continuous high-production settings, though they require specialized sharpening equipment.
