Description

Technical Field

[0001] The invention relates to the technical field of waste edge removal equipment, and in particular to a device for automatically removing waste edges of a precision plate sawing machine. Background Art

[0002] Precision saw is a key equipment in the production of non-ferrous metal sheets, which is used to obtain finished sheets of specified sizes. During the sawing process, the saw machine first cuts off both sides of the incoming material longitudinally to obtain the width dimension of the finished product, and then performs several transverse sawing according to the required length dimension of the finished product, and finally obtains several groups of finished sheets that meet the length and width dimension requirements. In this sawing process, the waste edges sawed off after the longitudinal sawing must be removed from the sawing table before the transverse sawing, otherwise the longitudinal cut waste edges and the raw material board will be sawed at the same time when the transverse sawing is performed.

[0003] In the prior art, when processing the waste edges, the sawing waste edges are first separated from the raw material board manually on the sawing table, and then the waste edges are bundled and lifted away by a crane, and finally the waste edges are unbundled for subsequent processing. The later processing of the waste edges is troublesome and wastes a lot of time, and requires a large number of manual machines to be used in coordination, which increases a lot of processing time. In addition, the labor intensity is high when processing the waste edges, which increases the labor force and the waste edge processing efficiency is low. Therefore, the present invention proposes a device for automatically removing waste edges of a precision plate sawing machine. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a device for automatically removing waste edges of precision plate saws.

When a certain collection weight is reached, the collection box is automatically pushed out to process the collected waste. The operation of removing the waste edges is simple and convenient. After the waste edges of the precision plate are removed, the processed plates can be conveniently moved and collected, thereby improving the efficiency of processing the waste edges of the precision plate.

[0041] The adjusting part adjusts the position of the sealing push plate 32. When thrust is generated on the sealing push plate 32, the sealing push plate 32 generates pressure on the hydraulic oil inside the hydraulic chamber 31.

The hydraulic oil increases the pressure inside the boosting chamber 37 along the hydraulic conduit 30, and pushes the sealing plug 36 inside the boosting chamber 37 to move upward. The sealing plug 36 moves upward and drives the sliding plate 2 to move upward through the lifting push rod 35. The upward movement of the sliding plate 2 lifts the precision plate, and the precision plate slides along the sliding plate 2 for collection. After the collection is completed, force is applied to the rotating disk 34 in the opposite direction to reset the sliding plate 2.

[0044] The rotation of the rotary motor 16 is controlled by the PLC controller 18.
