Description

Case bottom plate bending die

The technical field is as follows:

The utility model belongs to the technical field of the aeroengine machine case, in particular to machine bottom plate bender.

Background art:

A large number of circuit boards and other important electronic devices are installed in the aircraft engine case, and the requirement on the dimensional accuracy of the case is high. After the chassis base plate is formed by punching, the formed plate needs to be bent, and how to bend the plate is a problem to be solved by people.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

The utility model has the following contents:

An object of the utility model is to provide a machine bottom plate bender to overcome the defect among the above-mentioned prior art.

In order to achieve the above object, the utility model provides a machine bottom plate bender, include: the device comprises an upper die, a left lower die, a right lower die, a stripper plate, a spring, a lining plate and a bottom plate; the upper die is connected with a die handle of the punching machine, a lining plate is arranged on the bottom plate, a left lower die, a right lower die and a stripper plate are arranged on the lining plate, the spring is arranged on the bottom plate, and the spring penetrates through the lining plate and is connected with the stripper plate; the center line of the stripper plate is aligned with the center line of the upper die, and the left lower die and the right lower die are symmetrically arranged by taking the center line of the stripper plate as a central axis; the upper die is of a trapezoidal structure, and the width of the bottom surface of the upper die is consistent with that of the stripper plate; the improved machine case bottom plate bending device is characterized in that mounting grooves communicated with each other are formed in the left lower die, the right lower die and the discharging plate, the mounting grooves extend from one end of the left lower die to the end portion of the right lower die through the discharging plate, a machine case bottom plate is placed in the mounting grooves, the upper die is pressed down to press the discharging plate, the discharging plate is pressed tightly by the aid of elasticity of springs, in the descending process of the discharging plate, the two sides of the machine case bottom plate are deformed and bent under extrusion of the left lower die and the right lower die, after bending is completed, the upper die resets, the springs push up, the discharging plate.

Compared with the prior art, the utility model discloses following beneficial effect has:

The case bottom plate bending die is adopted to bend the case bottom plate through the left lower die and the right lower die, the lower dies are symmetrically arranged by taking the upper die as a center, the two sides of the case bottom plate can be accurately bent into shapes with the same size, and the production precision is improved.

Description of the drawings:

FIG. 1 is a schematic view of the bending die structure of the chassis base plate of the present invention;

The reference signs are: 1-upper die, 2-left lower die, 3-right lower die, 4-stripper plate, 5-spring, 6-lining plate, 7-bottom plate, 8-mounting groove, 9-chassis bottom plate and 10-punch die shank.

The specific implementation mode is as follows:

The following detailed description of the embodiments of the present invention is provided, but it should be understood that the scope of the present invention is not limited by the embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

Example 1

As shown in fig. 1, a bending die for a bottom plate of a machine case comprises an upper die 1, a left lower die 2, a right lower die 3, a stripper plate 4, a spring 5, a lining plate 6 and a bottom plate 7; the upper die 1 is connected with a die handle 10 of the punching machine, a lining plate 6 is arranged on the bottom plate 7, a left lower die 2, a right lower die 3 and a stripper plate 4 are arranged on the lining plate 6, the spring 5 is arranged on the bottom plate 7, and the spring 5 penetrates through the lining plate 6 and is connected with the stripper plate 4; the center line of the stripper plate 4 is aligned with the center line of the upper die 1, and the left lower die 2 and the right lower die 3 are symmetrically arranged by taking the center line of the stripper plate 4 as a central axis; the upper die 1 is of a trapezoidal structure, and the width of the bottom surface of the upper die 1 is consistent with that of the stripper plate 4; the mounting groove 8 that is provided with the intercommunication on left side lower mould 2, right lower mould 3, the stripper 4, mounting groove 8 extends stripper 4 to 3 tip on the right side lower mould from 2 one end on the left side lower mould.

Placing machine case bottom plate 9 in mounting groove 8, starting the punching machine, going up mould 1 and pushing down, pushing down stripper 4, the elasticity of spring 5 makes stripper 4 compress tightly machine case bottom plate 9, and in stripper 4 decline in-process, machine case bottom plate 9 both sides warp under the extrusion of left lower mould 2, right lower mould 3 and bend, after the completion of bending, go up mould 1 and reset, spring 5 pushes up, stripper 4 rises the return, takes off machine case bottom plate 9 by the workman, and machine case bottom plate 9 production is accomplished.
