1. Introduction
Open-bottom die-drive press is designed to handle a variety of jobs that demand precise die control and pressure for stamping, forming, and drawing operations. This press usually consists of a base, a bed, a slide, and a ram. Each element is an integral and important part of the pressing operation and must be configured or sized and adjusted to meet the requirements of the job.
2. Press Speeds
Open bottom drive presses offer a range of press speeds in order to meet the requirements of the job. The ram will act as the primary mover, while the bed and slide can be used to further support the load. Slow press speeds are common in open bottom drive presses and are used to reduce die wear on high-precision jobs, while faster speeds are available for more general or roughing operations.
3. Stroke
Stroke length for an open-bottom drive press is determined by the requirements of the application. Stroke length will typically range from a few millimeters up to several hundred millimeters depending on the size of the part being produced. On larger parts, such as auto body panels, longer strokes may be needed in order to achieve a deeper draw.
4. Die Shape
Die shape is a crucial element in the production of parts on open bottom drive presses and will often depend on the shape of the part being produced. Common shapes include flat, round, square, rectangle, and irregular. Different shapes will require different punches and dies depending on the complexity of the job.
5. Force
Force is the amount of pressure applied to form, shape, and eventually, finish the part. The size and speed of an open bottom drive press will determine the amount of force it can generate, generally, the bigger and faster the press, the higher the force it can produce.
6. Safety
The operation of open bottom drive presses requires extreme attention to safety. The press is a tool designed to generate just enough force to form and shape the part without causing any harm to the operator. In order to ensure a safe pressing operation, operators must be properly trained and the press must be inspected regularly and follow all safety regulations set forth by the manufacturer.
7. Summary
Open bottom drive presses are precise tools designed to produce a high-quality part in a timely fashion. Their ability to control force, stroke length, and die shape range makes them a versatile tool for a wide range of applications. It is important to treat the press with care and caution to ensure a safe pressing operation every time.
