Abstract
The utility model discloses a bending mould for a Z-shaped piece, which comprises a male mould, a female mould, a shank and a lower mould seat, wherein the male mould is fixedly connected with the lower part of the shank; the female mould is fixedly connected with the upper part of the lower mould seat; the lower end surface of the male mould is Z-shaped; a first concave hole is formed in the female mould; an ejector rod and a vibration block are arranged on the left and right of the interior of the first concave hole respectively; the upper side surfaces of the ejector rod, the vibration block and the female mould are on the same horizontal plane; a spring is arranged below the ejector rod; the vibration block is rotationally connected onto the female mould; a groove is formed in the right side of the ejector rod; a projection is arranged on the left side of the vibration block and placed in the groove; the ejector rod is connected into the first concave hole in a sliding manner. The bending mould has the advantages that the gravity centers of workpiece blanks are stable after placement; the production efficiency and product precision are high; the structure is simple; the operation is convenient.
Description
Technical field
The utility model relates to stamping technology field, relates in particular to a kind of Z-shaped bending die.
Background technology
Z-shaped adopts bending die to be stamped to form conventionally, and Z-shaped general step bending die exists product blank to put the problem of crank, and production efficiency is low, and by after Z-shaped curved pressure, Z-shaped can produce resilience, and Product Precision is low, affects product quality.
Utility model content
Problem to be solved in the utility model is, for Z-shaped of prior art, exists product blank to put crank in process, and production efficiency is low, the defect that Product Precision is low, provide a kind of product blank to put steadily of centre of gravity, production efficiency is high, Z-shaped the bending die that Product Precision is high.
The purpose of this utility model is achieved through the following technical solutions.Z-shaped bending die, comprise punch, die, die shank and die shoe, punch is fixedly connected on die shank below, die is fixedly connected on die shoe top, the lower surface of described punch is zigzag, die is provided with the first shrinkage pool, in the first shrinkage pool, be provided with push rod and swinging block, push rod and swinging block lay respectively at left side and the right side in the first shrinkage pool, the upper side of push rod and swinging block and the upper side of die are in same level, the below of push rod is provided with spring, swinging block is rotatably connected on die, the right side of push rod is provided with groove, the left side of swinging block is provided with projection, projection is positioned at groove, push rod is slidably connected in the first shrinkage pool.During work, product blank is placed on die, because the upper side of push rod and swinging block and the upper side of die are in same level, therefore product blank is put steadily of centre of gravity, do not need repeatedly to put, improved production efficiency, patrix is descending, and punch is pressed on product blank, patrix continues descending, push rod down sliding, extrudes product shape, and punch continues descending, push rod drives to swing and counterclockwise rotates to piece, product by stressed correction, makes product can not produce resilience between punch, push rod and swinging block, and Product Precision is high.
As preferably, described the first shrinkage pool is rectangular opening, and the cross section of push rod is rectangular, and the cross section of swinging block is rectangular, simple in structure, easy to process.
As preferably, described die shoe is provided with the second shrinkage pool, and the lower end of push rod is positioned at the second shrinkage pool, and spring is positioned at the second shrinkage pool.
As preferably, on the left of described die upper side, be provided with location-plate, the rear side of die upper side is provided with alignment pin, facilitates product blank location, easy to operate.
The beneficial effects of the utility model are, product blank is put steadily of centre of gravity, and production efficiency is high, and Product Precision is high, simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of counterdie.
The specific embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Fig. 1 to Fig. 2, Z-shaped bending die, is comprised of upper die and lower die, and patrix comprises punch 2 and die shank 1, and punch is screwed and is connected to die shank below, and the lower surface of punch is the zigzag of step, and low right side, left side is high.Counterdie comprises die and die shoe 6, die is comprised of with right half die 9 left half die 5, left half die is cuboid, right half die basic configuration is also cuboid, the left side opening of right half die is provided with U-shaped groove, left half die and right half die fit, and be all screwed and be connected to die shoe top, U-shaped groove forms the first shrinkage pool between half die and right half die, the first shrinkage pool is rectangular opening, in the first shrinkage pool, be provided with push rod 4 and swinging block 10, the cross section of push rod is rectangular, the cross section of swinging block is rectangular, push rod and swinging block lay respectively at left side and the right side in the first shrinkage pool, the upper side of push rod and swinging block and the upper side of die are in same level, the below linking springs 7 of push rod, die shoe is provided with the second shrinkage pool, the lower end of push rod is positioned at the second shrinkage pool, spring is positioned at the second shrinkage pool.In the U-shaped groove of right half die, be provided with rotating shaft 8, the two ends of rotating shaft are connected to the front and back side of right half die, and swinging block is rotatably connected in rotating shaft, and the right side of push rod is provided with groove, and the left side of swinging block is provided with projection, and projection is positioned at groove.Between left half die and the front and back side of right half die and the left surface of swinging block, form a space, push rod is positioned at this space and coordinates with this spatial joint clearance, and push rod is slidably connected therein.Described die upper side screw connected positioning plate 3 for left side, the rear side of die upper side is provided with alignment pin 12, and alignment pin is embedded on die.During work, product blank is placed on die, because the upper side of push rod and swinging block and the upper side of die are in same level, therefore product blank is put steadily of centre of gravity, do not need repeatedly to put, improved production efficiency, patrix is descending, and punch is pressed on product blank, patrix continues descending, push rod down sliding, extrudes product 11 shapes, and punch continues descending, push rod drives to swing and counterclockwise rotates to piece, product by stressed correction, makes product can not produce resilience between punch, push rod and swinging block, and Product Precision is high.
The above is the preferably specific embodiment of the utility model, not with this, limits practical range of the present utility model.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
