Description

Eight-bending bottom plate one-time forming stamping die

Technical Field

The utility model belongs to the technical field of the sheet metal component machine-shaping and specifically relates to an eight bottom plate one shot forming press dies of bending are related to.

Background

At present, when a bottom plate part is machined, four horizontal parts on the bottom plate part need to be subjected to U-shaped bending machining, so that four horizontal parts on the bottom plate part form four U-shaped parts.

At present, the four horizontal portions on the bottom plate part are bent manually by a bending machine, and each horizontal portion needs to be bent twice (eight times of bending in total) to form four U-shaped parts. However, manual bending is high in labor intensity, time-consuming, low in efficiency and high in rejection rate, and labor cost is increased, and the consistency of the bent and formed U-shaped part is poor.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve present manual intensity of labour who bends big, consuming time, it is inefficient, increase the cost of labor, and the U type spare uniformity after the shaping of bending is relatively poor, the higher problem of disability rate provides a simple structure, convenient operation, and the part can one shot forming, and machining efficiency is high, can practice thrift the energy consumption, reduces eight of cost of labor's bottom plate one shot forming press die of bending.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an eight bottom plate one shot forming press dies of bending, includes the lower mould and can be up-and-down motion's last mould for the lower mould, the lower mould includes that lower bolster and interval are fixed in four down dies of bending on the lower bolster, be equipped with the punching press die cavity on the die of bending down, the punching press die cavity is open groove, and the open-top inboard of punching press die cavity is equipped with spacing step, go up the mould and include the cope match-plate pattern and be fixed in the last mould drift of cope match-plate pattern lower surface, go up the cavity shape looks adaptation of mould drift and punching. The upper die can reciprocate up and down relative to the lower die, which is a conventional technical means in the field, and therefore, the details are not described herein.

Preferably, a limiting bump is fixed on the lower template along the length direction, and the lower bending female die and the limiting bump are fixed on the lower template in a limiting manner through insertion. The cross section of the limiting convex block is in a shape like a Chinese character 'tu', a groove is arranged on the limiting convex block, and the lower bending female die is positioned in the groove and forms insertion limit with the limiting convex block so as to be fixed on the lower template.

Preferably, the limiting lug is connected with the lower template fixing nail through a screw.

Preferably, the limiting bump is cold-drawn flat steel.

Preferably, the limiting block is made of cold-drawn flat steel.

Preferably, an inner oblique chamfer is arranged at the opening of the stamping die cavity. An inner oblique chamfer is arranged at the opening of the stamping die cavity to play a role in guiding, so that the bottom plate part can be quickly and accurately clamped into the stamping die cavity.

Preferably, the turning part of the limit step is an inner circular chamfer. The turning part of the limiting step is designed to be an inner circle chamfer, so that the fracture caused by over concentration of stress during the stamping and bending of the bottom plate part can be effectively avoided.

Therefore, the utility model discloses following beneficial effect has:

(1) the inner side of the top opening of the stamping die cavity is provided with a limiting step which plays a limiting role and can prevent the bottom plate part from moving left and right when being bent;

(2) through the cooperation of last mould drift and punching press die cavity, can accomplish eight times bending shaping (the bottom plate part can one-time forming) on the bottom plate part through a punching press, the shaping uniformity is good, convenient operation, and machining efficiency is high, can practice thrift the energy consumption, reduces the cost of labor.

In the figure: the die comprises a lower die plate 1, a lower bending die 2, a stamping die cavity 3, a limiting step 4, an upper die plate 5, an upper die punch 6, a limiting block 7, a screw 8, an inner oblique chamfer 9, an inner oblique chamfer 10, a bottom plate part 11, a horizontal part 12 and a U-shaped part 13.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

The eight-bending bottom plate one-step forming stamping die comprises a lower die and an upper die capable of doing up-and-down reciprocating motion relative to the lower die, wherein the lower die comprises a lower die plate 1 and four lower bending female dies 2 fixed on the lower die plate at intervals, a limiting lug 7 is fixed on the lower die plate along the length direction, the lower bending female dies and the limiting lug are fixed on the lower die plate in a limiting mode through insertion fit, the limiting lug is connected with a lower die plate fixing nail through a screw 8, the limiting lug is cold-drawn flat steel, a stamping die cavity 3 is arranged on the lower bending female dies, the stamping die cavity is an open groove, an inner oblique chamfer 9 is arranged at an opening of the stamping die cavity (shown in figure 2), a limiting step 4 is arranged on the inner side of a top opening of the stamping die cavity, the turning position of the limiting step is set to be an inner chamfer 10, the upper die comprises an upper die plate 5 and an upper die.

The utility model has the operation process that: placing the horizontal part 12 on the bottom plate part 11 in a stamping die cavity, placing the horizontal part 12 on the bottom plate part on a limiting step to position the horizontal part, starting a forming stamping die, pressing down an upper die punch to stamp and bend the horizontal part on the bottom plate part to form a U-shaped part 13 (shown in figures 3 and 4), and finally taking down the bottom plate part.

The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the scope of the claims.
