Description

Bending machine

Technical Field

The utility model relates to a panel technical field that bends specifically is a bender.

Background

Bending is the most important link in sheet metal manufacturing, and the quality of bending directly influences the manufacturing of the subsequent process and the quality of the whole product. The bending machine mainly comprises a workbench, an upper die, a lower die, a hydraulic mechanism and the like, wherein the inner side surface of a workpiece bending part is subjected to compression deformation in the bending process, the outer side surface of the workpiece bending part is subjected to tensile deformation, the compression deformation and the tensile deformation are maximum on the surface of a material, and the deformation is gradually reduced along with the gradual penetration to the thick inner part.

In the plate bending process, the plate is bent to be in a required shape through the matching of the upper die and the lower die, when the plate is bent, the plate is often subjected to position deviation when the plate is bent due to the fact that the lower die is fixed in position and is not completely compressed, and bending failure is caused, and the wider plate cannot be bent for many times due to the fact that the upper die is single in shape. To this end, we propose a bending machine.

Disclosure of Invention

An object of the utility model is to provide a bender to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a bending machine, includes the workstation, be fixed with the support frame on the workstation, there is the last mould through nut and screw connection on the support frame, the workstation mesa is opened there are spout and rectangular channel, and closing device passes through spout and rectangular channel and workstation sliding connection, closing device includes the slider, and the lower mould passes through the slider to be fixed on the workstation.

Preferably, the workbench surface is provided with four sliding grooves and a rectangular groove which are in sliding connection with the pressing device.

Preferably, closing device, including slide rail, fixed plate, carousel, screw rod and slider, the slide rail is fixed inside the spout, the slider passes slide rail and workstation sliding connection, there is the fixed plate through the fix with screw at the rectangular channel both ends, set up threaded hole on the fixed plate, the screw rod passes fixed plate and screw hole spiro union, and the one end and the carousel of screw rod are fixed, and the other end passes through the bearing and is connected with the slider rotation.

Preferably, the rectangular groove is arranged in the middle, and the sliding grooves are arranged on two sides of the rectangular groove.

Preferably, the upper die is bent in shape.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an it uses to go up mould, lower mould and closing device's cooperation, can make quick, the accurate lower mould fix a position and compress tightly, goes up the shape of buckling of mould, makes the bender can buckle many times to the panel of broad, has solved the unsuccessful of bending like this, and the precision of bending is not enough, and the slow problem of mould adjustment has improved the quality of the product of bending, has promoted work efficiency, has saved the time.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a bending machine, includes workstation 1, be fixed with support frame 2 on workstation 1, there is last mould 5 through nut and screw connection on

support frame

2, 1 mesa of workstation is opened there are spout 6 and rectangular channel 8, and closing device 3 passes through spout 6 and rectangular channel 8 and workstation 1 sliding connection, closing device 3 includes slider 12, and lower mould 4 passes through slider 12 to be fixed on workstation 1, the utility model discloses a closing device 3, last mould 5 and lower mould 4's cooperation is used, has solved the bender at the during operation, because of the deviation of lower mould 4 position control, and the product precision of bending that broad panel can't bend many times and lead to is not high, and the failure of buckling, the slow problem of mould regulation.

The table-board of the working table 1 is provided with four sliding grooves 6 and a rectangular groove 8 which are connected with the pressing device 3 in a sliding manner, the two sliding grooves 6 on the two sides play a role of stabilizing the sliding block 12, so that the two sides of the sliding block 12 can slide simultaneously without dislocation, and the rectangular groove 8 is used for preventing the sliding position of the sliding block 12 from being blocked because the space of the working table 1 is not occupied.

Compressing device 3, including slide rail 7, fixed plate 9, carousel 10, screw rod 11 and slider 12, slide rail 7 is fixed inside 6 spouts, slider 12
