NC feeder, NC servo Feeder

As a new type of high precision and high stability feeding equipment, the appearance of NC servo feeder is no accident, but has its inevitable reasons.

First, because of the stamping industry on the precision of automation equipment requirements, roller feeder, air feeder These traditional feeding equipment can not fully meet the requirements of stamping production, so the manufacturer in the traditional feeder on the basis of R & amp; D and production of NC servo feeder;

Second, NC servo feeder itself has other feeding equipment can not achieve the advantages, it is based on these significant advantages, so that the NC servo feeder as soon as the emergence of the customer's widespread favor, and gradually replaced the roller feeder has become the most mainstream feeding equipment, with punch, Shearing machine, Hydraulic press and other processing equipment is widely used in automotive, hardware, electronics, computers and other manufacturing industries in a number of fields.

The concept of servo-driven roll feeds involves the use of a closed-loop positioning drive, usually a servomotor, to control the index position of the feed rolls. A servo-powered unit begins its motion in response to a signal from the press. It is capable only of a finite, minimum index time, which is based on the amount of power it can deliver and the load that it sees. As a result, a servo-powered unit's finishing point can vary with the press speed. The faster the press runs, the later in the stroke a servo-powered unit finishes. Their top speeds still are limited by the available drive power, as opposed to press-driven feeds that can run as fast as the press and tooling.

Servo drive technology has been used in press feeding applications for more than two decade, and it has now matured to the point that these drives are more reliable and less expensive than they were in the past. Servo systems' modularity and self-diagnostic features have improved their functionality.

Servo-driven roll feeds have many of the same advantages press-driven feeds have, such as minimal space requirements, low maintenance, and high speeds.

However, servo feeds also provide benefits that press-driven units cannot because a microprocessor-based control gives them capabilities such as programmable move patterns, self-diagnostics, autocorrection, and the ability to communicate with automation. Servo-driven roll feeds are available in several configurations, including:

  • Conventional two-roll units
  • Four-roll units (sometimes specified when processing thick materials)
  • Feeder/straighteners (for space-saving requirements)
  • Push-pull units (typically for light-gauge materials)
  • Zigzag units (for better material utilization when stamping nestedround blanks)

Servo feed control packages vary in sophistication, from simple-to-use, single-setup controls with thumbwheels or keypads to complex systems that allow programming of elaborate multiaxis move patterns, control of auxiliary functions and devices, and varying levels of job recipe storage memory and communications capability. Most servo feeds offer some degree of integration with the press control to provide constant contact with the press operations:

  • "Hand-shaking" on job setups and recipe storage
  • Simplified operator interface that allows single point of data entry/verification and a touch-screen display that delivers operational prompts and diagnostic information and help screens
  • Faster maintenance reminders or fault information via a single control station
  • More control of peripheral equipment such as in-press transfer units, safety equipment, and die monitoring systems

Press-driven Roll Feeders - Cam Driven

Press-driven Roll Feeders - Cam Driven

Roll feeds that are press-driven, such as rack-and-pinion or cam, are always synchronized with the rotation of the press. The feed's motion begins at a predetermined point in the press cycle and finishes at another predetermined point regardless of press speed or die engagement. Although the index speed must increase or decrease to keep pace with the press, the feed can draw as much power as it needs from the press to accomplish this within the limitations of the mechanical coupling of the feed to the press.

This synchronization feature makes press-driven feeds suitable for high-speed indexing, in-die transfers, and for use with unloaders and other applications that require feed motion to be tied to press rotation to prevent a collision.

Drawbacks to most press-driven feeds are their difficulty in adjusting the feed length, lack of inching capability, and absence of controls interface. Most require that gear sets, rollers, or mechanical linkages be changed to adjust feed length. Because press-driven feeds are coupled directly to the press rotation, they lack the ability to jog the strip for threading. Additionally, because of the lack of electrical controls, mechanical feeds cannot accept setup information from or provide feedback to press controls or automation systems.

About High Speed Roll Feeder

High speed roll feeder is one of the most popular feeding machine in the industry currently, match with traditional punch\ pneumatic punch\ mechanical punch and high speed punch in stamping production line.  It comes with low fault rate\ low energy consumption\ high automation\ stable and high speed. But every coin has two sides, high speed roll feeder has strict installation requirements than other type feeder. 

Pressmach’s high speed roll feeder adopts eccentric disk\ rocker arm\ pull rob\ cross joint and driven shaft to drive the feeding roll as the way of feeding. The feeder itself has no power and is powered by an eccentric disk mounted on the output shaft of the punch.

Pay attention to the following when using:

  • The punch must equipped with an output shaft. Regardless of which press is used, the premise of the installation is that the punch has an output shaft. If the punch does’t with output shaft itself and the customer still require to choose high speed roll feeder. Customer need to ask punch supplier to install the output shaft for the press in advance or to vote for an NC-feeder.
  • Clearly material width\ material thickness and feeding step.
  • Clearly the requirement of punching speed.
  • If the feeding length of high speed roll feeder has a big change, need to readjust the rocker arm. Because the angle between the rocker arm and the pull rob will change. At this time, the pull rob should be rotated to make the angle between the rocker arm and the pull rob become 90 degrees when the punch stops at the dead point position, avoiding the breakage of the rocker arm or the drive shaft.
  • Readjust the feeding height of high speed roll feeder when change mold on the punch. Multiple sets of stamping molds should be used in the stamping production process, and the mold height of different molds are different. Only by ensuring the feeding height of the feeder and the height of the mold are the same, the feeding can accurately and smoothly.
