Technical Field

The utility model belongs to the technical field of the equipment of bending, more specifically say, relate to a bender dam device Z axle subassembly.

Background

The bending machine is a machine capable of bending a thin plate and comprises a support, a workbench, a clamping plate and a rear material blocking plate, wherein the workbench is arranged on the support and consists of a base and a pressing plate, and the base is connected with the clamping plate through a hinge. The bending machine product is widely applicable to the industries of electromechanics, sheet metals, light industry, aviation, ships, instruments, electrical appliances, stainless steel products, steel structure buildings, metallurgy and the like, is used for bending various steel plates, stainless steel, copper plates, aluminum plates and non-metal material plates, can be folded into V-shaped, arc-shaped, circular or right-angle shapes and the like, and can be designed and processed into a special-shaped die according to requirements.

The rear stock stop of the bending machine is an important working mechanism in the bending machine, and has the function of positioning metal plates up and down, left and right and front and back, so that the position of the rear stock stop needs to be adjusted according to the difference of the shapes and the sizes of bent workpieces. The existing rear stock stop device of the bending machine has various structural forms, but the structural forms are approximately the same, generally, a beam is supported through a linear rail arranged on wall plates on the left side and the right side, a stop finger or a height adjusting assembly is arranged on the beam, and the stop finger is arranged to realize the adjustment of the stock stop position. This kind of structural style, the parts of back dam device all are the relative scattered installation, the integrated level is lower, need a plurality of spare parts to assemble in proper order on the bender, not only the installation is wasted time and energy, the dam precision is low, and its commonality and interchangeability are relatively poor, it is very inconvenient to exchange between different specifications or the same specification bender to use, thereby cause a model bender must match only one kind of back dam device, even exchange between two benders of the same specification and use same back dam device also very difficult, so every production a bender, a back dam device of correspondence needs production, the cost improves greatly, the stock has also been increased, be difficult for energy saving and consumption reduction.

And the front and back movement of the existing rear material blocking device is driven to be positioned by a servo motor, the up and down movement is realized by manually rotating a turntable, and the left and right movement is manually adjusted by loosening and screwing screws. The operating state of the material blocking device can be different according to operators due to the problems of operation proficiency and experience judgment of the operators. Therefore, the positioning accuracy of the material blocking device cannot be guaranteed, the profile accuracy of the product is reduced or the product quality is uneven, and the positioning efficiency is relatively low. Meanwhile, the material blocking device has relatively poor impact resistance, and the requirement of large-angle bending cannot be met.

In view of the above problems, the applicant filed patent application nos.: CN201710829801.2, published date: patent literature 12 and 29 in 2017 discloses an integrated intercommunication type rear material blocking device of a bending machine, and belongs to the technical field of bending machines.
