Abstract

The utility model discloses a kind of bender limiting devices, including upper die of bending machine, bender lower die, operation panel, L bars, mechanical position limitation sensor, adjusting L bars graduated scale, L bar clamp devices.A kind of bender limiting device of the utility model solves the problems, such as that existing bender is unable to control bender bending upper die and moves to bending lower die lower dead point position.

Description

A kind of bender limiting device

Technical field

The utility model belongs to position-limit mechanism field more particularly to a kind of bender limiting device.

Background technology

Bender is the one kind belonged in metal forming machinery, and main function is exactly metal-working industry.It is various not by apolegamy Same mold can carry out plate crimp, stretching, pressure circle, punching etc..The working method of existing bender is workbench and work The workpiece made on platform is motionless, meets work requirements by way of the downward dead-centre motion of bending upper die.The movement of existing bender Mode is divided into a dynamic formula, individual sport formula, reciprocating motion type, existing bender there are the problem of to be unable to control in bender bending Mould moves to bending lower die lower dead point position.

Utility model content

The purpose of this utility model is to provide a kind of bender limiting devices, it is intended to solve the above problems.

To achieve the goals above, the technical solution of the utility model is a kind of bender limiting device of design, including folding Bender upper mold, operation panel, L bars, mechanical position limitation sensor, adjusts L bars graduated scale, L bar clamp devices at bender lower die； The L bars are mounted on by L bar clamp devices on upper die of bending machine；Mechanical position limitation sensor is equipped with below the L bars；The machine Tool limit sensors welding steel, the steel plate are mounted on bender cabinet；It is equipped with below the L bars clamp device for surveying Determine the adjusting L bar graduated scales of L bar displacement distances；The operation panel connects upper die of bending machine.

Further, the L bars, L bar clamp devices are made of solid Q235 ordinary carbon steels.

Further, the L bars clamp device connects upper die of bending machine by welding manner, and L bars pass through two M6 jackscrews It is fixed on L bar clamp devices.

Further, the mechanical position limitation sensor is on the steel plate of 10 × 30mm.

The advantages of the utility model and advantageous effect are：

（1）Bender can adjust the position that bending upper die is moved to bending lower die according to actual demand.

（2）Bending Mould cost is reduced, since demand of the plate to bending of each project is different from, therefore for difference The plate of demand usually requires to make different Bending Moulds, requires variation little certain bendings, only the bending depth In the case of difference, as long as the distance that adjustment bending upper die presses to dead point can be realized, it is not necessarily required to remake bender Tool.

（3）Processing and debugging is difficult：Bender needs to carry out bender progress precision tune after more mold exchange in actual production Examination, it is ensured that the accuracy of bending plate.Traditional method is debugged tired because adjustment accuracy can only be adjusted by mold It is difficult.And it can simply carry out debugging dead-centre position using the structure of the utility model.

Description of the drawings

Fig. 1 is the structure chart of bender upper and lower mould and workbench.

Fig. 2 is bender limit device structure schematic diagram.

Wherein, upper die of bending machine 1, bender lower die 2, operation panel 3, L bars 4, mechanical position limitation sensor 5, adjusting L bars are used Graduated scale 6, L bars clamp device 7.

Specific implementation mode

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this It encloses.

Embodiment：

A kind of bender limiting device, including upper die of bending machine 1, bender lower die 2, operation panel 3, L bars 4, machinery limit Level sensor 5 adjusts L bars graduated scale 6, L bars clamp device 7；The L bars are mounted on by L bar clamp devices on bender On mould；Mechanical position limitation sensor is equipped with below the L bars；The mechanical position limitation sensor welding steel, the steel plate are mounted on On bender cabinet；The adjusting L bar graduated scales for measuring L bar displacement distances are equipped with below the L bars clamp device；It is described Operation panel connects upper die of bending machine.

The L bars, L bar clamp devices are made of solid Q235 ordinary carbon steels.

The L bars clamp device connects upper die of bending machine by welding manner, and L bars are fixed on L bars by two M6 jackscrews On clamp device.
