Description

The cutting structure of cutting stock

Technical field

The utility model relates to realize the structure cut off to blank, the cutting structure of especially a kind of cutting stock.

Background technique

Develop with modern mechanical processing industry, the continuous improvement to the quality of cutting, required precision, to improving production effect Rate, reduce production cost, the requirement of automatic cutting function with high-intelligentization is also being promoted.In current mechanical processing process In, cutting usual way has hand cut, semi auto cutting machine cutting and numerical control cutting machine cutting.Hand cut, flexibly and easily, But hand cut is of poor quality, scale error is big, waste of material is big, following process heavy workload, while working condition is severe, production Low efficiency；Copying cutting machine in semi auto cutting machine, the quality for cutting workpiece is preferable, since it uses cutting die, is not suitable for In single-piece, small lot and big work piece cut, although other type semi auto cutting machines reduce labor intensity of workers, but its function Simply, it is only suitable for the part cutting of some relatively regular shapes；Numerical control cutting relatively manually and for semi-automatic cutting mode can With effectively improving plate cutting efficiency, cut quality, with mitigating operator labor intensity, but equipment is at high cost, uses Rate is not universal, and some medium-sized and small enterprises in China even use hand cut and semi-automatic cutting side in some large enterprises Formula is more universal.

Utility model content

The utility model will solve the disadvantage that the above-mentioned prior art, and spacing can voluntarily be fed, automatically cut off by providing one kind Cutting stock cutting structure, in the form of intelligentized control method will need to manually control originally cutting cutter device realize from Dynamicization cutting is thus greatly lowered compared to cost for the full-automatic cutter device of numerical control control, and easy to operate, It is high-efficient, it is suitable for all kinds of enterprises, it is convenient and efficient.

The utility model solves the technical solution of its technical problem use：The cutting structure of this cutting stock, including cut Disconnected unit, cutting unit include the linkage portion that knife rest and driving knife rest do cutting work, and linkage portion, which is equipped with, to be fixed on knife rest Fixed plate is equipped with mounting rod in fixed plate, and the lower end of mounting rod is fixed with connector, and the lower end of connector is connected with company Block is connect, link block lower end is connected with swing arm, is connected with chain on swing arm, and chain is by motor driven, and the two of chain End end is all connected to swing arm left and right ends.In this way, making knife rest may be implemented to rotate automatically using linkage portion, it is detached from artificial Automatic cutting is realized in control, and fixed plate is arranged on knife rest, and is provided with the mounting rod of connector, and link block and swing arm For the linkage structure connecting with mounting rod, link block is existed for connecting swing arm and mounting rod, swing arm by middleware chain The positive and negative rotation campaign of motor is lower to realize roll motion, rotates upwardly and downwardly fortune by the band movable knife rack that swings of swing arm Dynamic, sensor and inductor need to be only arranged in automatic cycle, and when motor rotates forward, knife rest rotates down certain angle, completes to cut It cuts, the cycle rotation inductor of cycle rotation sensor and lower section generates signal and contacts, and cycle rotation inductor is by signal feedback To master control, motor reversal, knife rest is rotated up certain angle and returns to original position, waits cutting order next time, thus may be used The time caused by rotation excess is saved, is improved efficiency.

It is further perfect, the limit base being flexibly connected for swing arm is equipped at the mid portion on swing arm.In this way, limit Seat gives the constraint before and after swing arm, prevents it from upwarping to both sides, so that swing arm only swings, guarantees the steady of linkage portion It is fixed to use

It is further perfect, activity is equipped between connector and link block, link block and swing arm, swing arm and limit base Interconnecting piece, active connection part are equipped with fixed link and are mounted on the sphere of fixed link.In this way, the structure is simple, using effect is good, It can be realized outside the rotation connection between connector and link block, link block and swing arm, swing arm and limit base, it can be with root According to the use angle for needing to adjust each, avoids generating interference in use, further strengthen the stability in use of linkage portion.

The utility model has the advantages that：The cutting structure of the cutting stock of the utility model uses the machine of compact dexterity Tool is driven chain structure, and complete machine electricity consumption is small, energy-efficient：Cutting speed is fast, high production efficiency, and a people can manage more, reduces Labour cost, good in economic efficiency, the form tolerance control precision of Cutting Length and slice is high, completes cutting work, cycle rotation Sensor and cycle rotation inductor driving motor realize that automatic positive and negative rotation is worthy to be popularized so that controlling knife rest does shuttling movement.
