Description

Sheet metal automatic bending machine

technical field

The utility model relates to the field of bending machines, in particular to a fully automatic bending machine for sheet metal.

Background technique

The bending die of the existing sheet metal bending machine is mainly to place the workpiece on the lower die, and press the workpiece through the stamping head of the upper die to complete the bending of the workpiece. The bending angle of the workpiece is mainly determined by the notch of the lower die. The length of the notch is determined by the length of the notch, and the bending degree of the bending part of the workpiece is different. In the actual production process, since the notch length is fixed, each lower mold can only adapt to one kind of bending Process requirements, however, the bending process requirements in actual production are various, so that the manufacturer must configure a large number of matching molds, not only the cost is large, but also the corresponding molds need to be replaced frequently during the production process. Time-consuming and labor-intensive, the production efficiency is low.

Contents of the invention

In order to solve the deficiencies in the prior art, the purpose of the utility model is to provide a sheet metal automatic bending machine capable of realizing different bending angles.

In order to achieve the above object, the utility model adopts the following technical solutions:

Automatic sheet metal automatic bending machine, including a machine table, a lower mold is arranged on the table surface of the machine table, and an upper mold driven by a lifting driver for lifting movement is arranged directly above the lower mold. The bottom of the upper mold has an arc shape the punch; the lower mold includes two lower modules that are slidably connected to the slide rail at intervals, and a bending notch is formed between the two lower modules; A remote drive assembly, the drive assembly includes a gear, a power source and two racks that mesh with the gears respectively, the two racks are respectively arranged on both sides of the gear and the teeth of the two racks are oppositely arranged, the bottom of the two upper modules They respectively extend to the bottom of the machine table and are respectively fixedly connected with a corresponding rack. The power source is an oil cylinder, and the push rod end of the oil cylinder is fixedly connected with one of the racks.

The lower module is provided with a roller at the corner of the notch.

The bottom of the machine table is respectively provided with limit slides parallel to the slide rails corresponding to each rack, and the backs of the racks are slidably connected to the corresponding limit slides.

The lifting driver is an oil cylinder.

The utility model adopts the above structure and has the following beneficial effects:

1. Through the cooperation of the gear and the two racks, the two lower modules are driven to approach or move away synchronously, so as to realize automatic and stepless adjustment of the length of the bending notch to meet different production needs, which not only reduces the cost of equipment investment , and increased production efficiency.

2. Set rotatable rollers on the two lower modules. When bending the sheet metal, the punch applies pressure to the sheet metal. When the sheet metal is stressed, the friction between the sheet metal and the die is changed by the sliding The friction force is changed to rolling friction force, which reduces the strain on the bending part of the sheet metal during bending, and also reduces the friction force, thereby effectively avoiding indentation.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail;

Detailed ways

As shown in Fig. 1 or Fig. 2, the utility model comprises a machine platform 1, a lower mold is arranged on the table surface of the machine platform 1, and an upper mold 3 driven by a lifting driver 2 for lifting movement is arranged directly above the lower mold. The bottom of the upper mold 3 has an arc-shaped punch 4; the lower mold includes two lower modules 6 that are slidably connected to the slide rail 5 at intervals, and a bending notch is formed between the two lower modules 6, and the machine table The bottom of 1 is provided with a drive assembly that drives the two lower modules 6 to approach or move away synchronously. The drive assembly includes a gear 7, a power source 8 and two racks 9 that mesh with the gear 7 respectively. The two sides of 7 and the teeth of two racks 9 are arranged oppositely, and the bottoms of the two upper molds 3 respectively extend to the bottom of the machine platform 1 and are respectively fixedly connected with a corresponding rack 9 (corresponding to each upper mold on the machine platform 1). 3 blocks are respectively provided with a relief hole that allows its bottom to pass through, and the relief hole is a bar-shaped hole parallel to the slide rail 5), the power source 8 is an oil cylinder, and the push rod end of the oil cylinder is connected to one of the racks. 9 fixed connections.

The lower module 6 is provided with a roller 10 at the corner of the notch. Rotatable rollers 10 are arranged on the two lower modules 6. When the sheet metal is bent, the punch 4 applies pressure to the sheet metal. When the sheet metal is stressed, the friction between the sheet metal and the lower module 6 The change from sliding friction to rolling friction reduces the strain on the bending part of the sheet metal during bending, and also reduces the friction, thereby effectively avoiding indentation.

The bottom of the machine table 1 is respectively provided with limit slides 11 parallel to the slide rails 5 corresponding to the racks 9 , and the backs of the racks 9 are slidably connected to the corresponding limit slides 11 . Can avoid tooth bar 9 to produce rocking in sliding process like this.

The lifting driver 2 is also an oil cylinder, which can effectively guarantee the stamping force.

Through the cooperation of the gear 7 and the two racks 9, the two lower modules 6 are synchronously approached or moved away, so as to realize automatic and stepless adjustment of the length of the bending notch to meet different production requirements, which not only reduces the cost of equipment investment , and increased production efficiency.
