Abstract

The utility model discloses a die of a punching plate material, which includes a concave die (1) and an arc convex die (2) which is provided with at least two arc-shaped work benches (10, 11) with varied radius. The utility model makes the plate material with different thicknesses can be punched for production on the same pair of die, therefore, the utility model has the advantages of simple structure and improvable production efficiency.

Description

The mould of punching press plate

Technical field

The utility model belongs to the sheet-metal press working field, is specifically related to a kind of mould of the different-thickness of punching press simultaneously plate.

Background technology

In punching production, sheet-metal press working can be made into complex-shaped part, and has simple to operately, and the production efficiency height be convenient to realize the advantage of mechanization and automated production, so sheet-metal press working is used widely.The circular arc Bending Forming Die is made up of punch and die at present.Usually the different circular arc press shaping die part of sheet metal thickness, need be on different Bending Forming Dies punching production.Because the different two boards material of thickness required internal diameter size when press shaping die is different, and the punch shape of a mold is single, therefore can not be with two disposable press shaping dies of plate that thickness is different, so the circular arc press shaping die part that sheet metal thickness is different, need be on different Bending Forming Dies punching production.

Summary of the invention

The purpose of this utility model is, a kind of mould of punching press different-thickness plate is provided.It can make the different-thickness plate can be on a secondary mould punching production simultaneously, therefore have advantage simple in structure, that can enhance productivity.

The purpose of this utility model is achieved like this: the mould of this punching press plate comprises the punch of a die and arc, and described punch is provided with the working bank of the arc that at least two radiuses do not wait.

Owing to adopted such scheme, on punch, be provided with the working bank of the arc that two radiuses do not wait, the radius difference of dependence working bank can once be carried out punching press to two different plates of thickness, and be obtained the inconsistent part of internal diameter size.So not only can reduce the fund of used device, the while can also be saved the working time and production efficiency is improved.

Owing to be provided with the cooling duct in punch, punch is provided with an end and is communicated with the cooling duct, and the cooling velocity to plate when compressed air enters into the cooling duct, can be accelerated in the cooling hole that the other end is communicated with working bank after exporting from the cooling hole.

Be equipped with on two top end faces of die on three locating pieces that are slidingly connected with die, for the plate of different in width, the locating piece of slip can be convenient to the location of plate is adjusted.Between per two locating pieces, be provided with one and be used to put and put mark thick, the thin plate material, be used to during punching press distinguish and place position thick, the thin plate material, prevent from that thick, thin plate material from misplacing to cause waste.

The utility model can be processed many circular arc press shaping die parts that sheet metal thickness is different simultaneously with same pair of mould, and design and the manufacturing expense that can save the circular arc bending die can improve utilization rate of equipment and installations and production efficiency simultaneously.

Description of drawings

Fig. 1 is an installation diagram of the present utility model;

Fig. 2 is that the die among Fig. 1 is fixed on the vertical view on the die socket;

Fig. 3 is the structure diagram of punch;

Fig. 4 is that the A of Fig. 3 is to cutaway view.

1 is die among the figure, and 2 is punch; 3 is locating piece, and 4 is guide pin bushing, and 5 is guide pillar, and 6 is convex mould base, and 7 is die socket, and 8 is counterbore, and 9 is the cooling duct, and 10 is first working bank, and 11 is second working bank, and 12 are the cooling hole.

The specific embodiment

With reference to Fig. 1, a kind of mould of punching press different-thickness plate, this mould comprise a die 1 and are positioned at the arc punch 2 of die top; Die is fixedly connected on the die socket 7 by screw; Being connected by guide pillar 5 between convex mould base 6 and the die socket, is matched in clearance between convex mould base and guide pillar; Guide pillar is provided with guide pin bushing 4.Be equipped with three locating pieces 3 on two top end faces of die, each locating piece can longitudinally move freely locating piece by forming being slidingly connected of can vertically moving between screw and the die.Be provided with one and be used to put and put mark thick, the thin plate material between per two locating pieces, the mark of present embodiment " H " is represented to put and is put thick plate place, and mark " B " is represented to put and put thin plate place (see figure 2).Punch 2 is screwed on convex mould base 6 by counterbore 8.On punch, be provided with first working bank 10 of arc, the working face on second working bank, 11, two working banks is arcwall face.The radius of first working bank is greater than the radius of second working bank, and first working bank is corresponding to the top of letter " B " mark, and second working bank is then corresponding to the top of letter " H ".Be provided with the cooling duct 9 of horizontal direction in the punch, be provided with cooling hole 12 in the described punch, an end in each cooling hole 12 is communicated with the other end and is communicated with a working bank with cooling duct 9.

The steel plate that with the punched blank is 8mm and 12mm is an example.When punching press, at first heating furnace is warming up to 600 ℃ ± 50 ℃, blank is put into stove, be incubated 15 minutes, blank is heated evenly, be warmed up to 800 ℃~900 ℃ then, blank after will heating is again put into the position of die according to above-mentioned method, Reference character " H " is put the steel plate of putting 12mm, mark " B " is put the steel plate of putting 8mm, starts stamping machine and carries out punch process, and the part behind the press shaping die needs to cool off under pressurize, during cooling on punch the cooling duct be blown into compressed air, accelerate cooling velocity.Start pickup when temperature drops to below 300 ℃.

The utility model is in processing external diameter unanimity, during the different circular arc press-bending part of sheet metal thickness, punch is designed to be with step-like concentric circle arc plane, two kinds of different-thickness sheet materials of punching press simultaneously.

Certainly,, then die is designed to be with step-like concentric circle arc plane if during the different circular arc press-bending part of the consistent sheet metal thickness of processing internal diameter, two kinds of different-thickness sheet materials of punching press simultaneously, such conversion all drops within the protection domain of the present utility model.

Punch of the present utility model can also be set to three working banks, with above-mentioned same method, and three kinds of different-thickness sheet materials of punching press simultaneously.

The utility model also can carry out punching press to a plate separately.
