It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

First, the cutter 4 refers to a device for cutting material, and the cutter 4 may be a sawing machine, for example. The blanking member 4 is shown as a saw blade of a sawing machine in fig. 1 and 3. Sawing machines are widely used in the field of machining, and have the main function of cutting large-size materials to finish the primary machining of the materials and prepare for subsequent finish machining.

For example, for a long-axis material, when the long-axis material is processed into a part, only a part of the material may be needed, that is, the long-axis material needs to be cut into several sections to facilitate subsequent finishing.

In the prior art, when the sawing machine is used for blanking, the sawing machine is operated manually, specifically, an operator judges at what part of a material to cut according to experience so as to form the material which is beneficial to subsequent processing and has shorter length. The operation mode causes low material blanking precision, namely the size of the cut material may not meet the requirement, thereby causing material waste. On the other hand, the operation mode is low in precision, when the material is required to be cut at the limit position, the material can be directly scrapped due to judgment errors of operators, and the processing cost of parts is further increased.

In order to solve the technical problem that in the prior art, an operator only judges the position of cutting off the material by experience to cause serious material waste, in some possible embodiments, the present disclosure provides:

That is, when the size of the workpiece material is too short, the workpiece material needs to be cut at the limit position, and at this time, the position of the feeder 2 or/and the discharger 3 is needed to realize that the cutter 4 cuts the workpiece material at the limit position, so as to improve the utilization rate of the workpiece material.

As shown in fig. 1, in some possible embodiments, the feeder 2 comprises a first gripper 6 sliding along the frame 1 and a first drive 7 driving the first gripper 6 to slide along the frame 1.

the discharger 3 retreats and prepares to clamp a workpiece M to advance and prepare for sawing, the material-free detection proximity switch 15 is arranged on the discharger 3 and moves along with the workpiece M, the workpiece M can be detected at ordinary times, when the workpiece M is short and cannot be detected, the material-free detection proximity switch 15 loses a signal, the reading of the second grating ruler 11 at the moment, namely the position b of the discharger 3, is recorded by the controller, the parameters are set through the touch screen, the distance a from the original point detection proximity switch 16 to the saw blade of the cutter 4, the shortest distance that the discharger 3 can clamp the workpiece M, namely the vice clamping length c, the width d of the discharger 3, and therefore the limit feeding length f = a + b + d-c of the discharger 3 can be calculated. Assuming that the dimension to be processed is e, the feeder 2 needs to be pulled by a distance between the two workpieces M to meet the dimension e to be processed, assuming that the dimension to be pulled is X, X = e-f, and a counting pulse is sent to the controller through the first grating ruler 10, and when the distance X is reached, the feeder 2 stops moving, and the length of the workpiece material at this time is the target dimension e required by the user.
