Abstract

The utility model relates to a bend and let bit architecture, constitute by last mould and lower mould, it includes the upper die base from top to bottom in proper order to go up the mould, the upper padding plate, the punch holder, the back of the body takes off the board and takes off the flitch, the lower mould includes the lower bolster from top to bottom in proper order, lower bolster and die holder, it still is provided with the drift of bending to go up the mould, the drift of bending is upwards fixed on the punch holder, the drift of bending runs through the punch holder from top to bottom, the back of the body takes off the board, take off flitch and lower bolster, the drift of bending is the rectangle structure, the lower mould still is provided with the die of bending, ejector pin and spring, the die of bending is fixed on the lower bolster through the pin, it is provided with the die cushion of bending to bend the die lower part, the ejector pin lower extreme is connected with the die holder through the spring, the ejector pin upper end is run through the die cushion of bending and is connected with the die lower part of bending. The utility model discloses a bend and let bit architecture, the constitutional detail is few, the motion is simple, and can accomplish the tip has dysmorphism or arch, die need be the bending structures who bends and step down.

Description

A kind of bending allows bit architecture

Technical field

The utility model belongs to machined die field, is specially a kind of bending and allows bit architecture.

Background technology

When bending, the end of billot has little bending and shaping protruding, need on die mold insert after bending Making and stepping down, in prior art, bending is required for completing with inclined sliding block structure, inclined sliding block structure complexity, Part is many, complicated movement.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of bending is stepped down knot Structure, this constitutional detail is few, motion simple, and can complete end has abnormity or projection, die to need to do to roll over The curved bending structure stepped down.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of bending allows bit architecture, is made up of upper die and lower die, upper mold include the most successively upper bolster, Upper padding plate, train wheel bridge, the back of the body take off plate and stripper plate, and lower mold includes lower bolster, lower bolster the most successively And die shoe, upper mold is additionally provided with Bending punch, and Bending punch is upwards fixed on train wheel bridge, and bending is rushed Head from top to bottom runs through train wheel bridge, the de-plate of the back of the body, stripper plate and lower bolster, and Bending punch is rectangle structure, Lower mold is additionally provided with bending female die, push rod and spring, and bending female die is fixed by a pin on lower bolster, Bending female die bottom is provided with bending female die cushion block, and push rod lower end is connected with die shoe by spring, top Bar upper end is run through bending female die cushion block and is connected with bending female die bottom.

Described bending female die side is provided with and allows bit architecture.

Described lower bolster is additionally provided with bending female die fixed block, steady for fixing the relative position of bending female die Fixed.

The beneficial effects of the utility model: constitutional detail is few, motion is simple, can complete end has abnormity Or projection, die need to do the bending structure that bending is stepped down.

Fig. 1 is structural representation of the present utility model.

In figure, label is described as follows:

1-upper bolster；2-upper padding plate；3-train wheel bridge；The de-plate of the 4-back of the body；5-stripper plate；6-bending female die is solid Determine block；7-lower bolster；8-lower bolster；9-die shoe；10-Bending punch；11-bending female die；12- Allow bit architecture；13-pin；14-bending female die cushion block；15-push rod；16-spring.

Detailed description of the invention

Below by specific embodiment, the utility model is described in further detail, and following example simply describe Property, it not determinate, it is impossible to limit protection domain of the present utility model with this.

As shown in drawings a kind of bending allows bit architecture, is made up of upper die and lower die, and upper mold from top to bottom depends on Secondary including upper bolster 1, upper padding plate 2, train wheel bridge 3, the de-plate 4 of the back of the body and stripper plate 5, lower mold is from top to bottom Including lower bolster 7, lower bolster 8 and die shoe 9 successively, upper mold is additionally provided with Bending punch 10, bending Drift is upwards fixed on train wheel bridge, and Bending punch from top to bottom runs through train wheel bridge, the back of the body de-plate, stripper plate And lower bolster, Bending punch is rectangle structure, lower mold be additionally provided with bending female die 11, push rod 15, Spring 16 and bending female die fixed block 6, bending female die is fixed on lower bolster by pin 13, bending Die bottom is provided with bending female die cushion block 14, and bending female die side is provided with and allows bit architecture 12, bending Die fixed block is stable for the relative position fixing bending female die, and spring and die shoe are passed through in push rod lower end Being connected, push rod upper end is run through bending female die cushion block and is connected with bending female die bottom.

During mould Guan Bi, upper mold moves downward, and material strip contacts with bending female die, and bending female die is along with upper mold The increasing of downforce, can overcome the active force of spring, rotate counterclockwise around pin, and last die turns flat, Mould closes dead, and Bending punch moves downward, and completes flexing movement, and the bit architecture that allows of bending female die can allow Drive crotch.

When mould is opened, upper mold moves upward, and after upper mold sails out of material strip, power is passed by spring by push rod Delivering on bending female die, bending female die stress rotates counterclockwise around pin, rotates to solid with bending female die Till determining block contact, now getting out of the way the crotch of material strip, material strip is deviate from, and completes flexing movement.

Above the technical solution of the utility model is done exemplary description, it should explanation, not In the case of departing from the core of the technical program, any simple deformation, amendment or other this area skills Art personnel can not spend the equivalent of creative work to each fall within the protection domain of this patent.
