Abstract
The utility model discloses a punching mould for the curved surface a hanging rack of a water heater. The mould consists of a hollowing die, a discharge plate, a piecing punch, a small guide column, a compression spring, a discharge screw, a punch retainer, a mould handle and a mould frame, wherein the mould frame consists of an upper mould frame and a lower mould frame; the hollowing die used for placing stamping parts is arranged on the lower mould frame; the shape of working end surface of the piercing punch is adaptive to that of the curved surface of the stamping parts; the piercing punch is arranged on the upper mould frame by the punch retainer; the discharge plate is arranged on the discharge screw and the position between the hollowing die and the piercing punch; the compression spring is sheathed on the discharge screw and positioned between the discharge plate and the upper mould frame; the mould handle is connected with the piercing punch; and the small guide column used for limiting the running direction of the discharge plate in descending of the piercing punch is arranged on the mould frame. In the utility model, the piercing punch is not easy to break off, so that the service life of the punching mould is prolonged.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of hanger curved surface punching die.
Background technology
Hole processing is the punch process difficult point always on the curved surface such as cambered surface, sphere, and main cause is that machined surface is not the plane, and the mould punch is stressed not steady when punching, causes the mould punch to fracture easily and influences die life.
Summary of the invention
The purpose of this utility model provides a kind of curved surface punching die.This mould adopts guiding stripper structure, has solved the problem that the perforating die punch fractures effectively, has prolonged the service life of mould.
The purpose of this utility model is achieved through the following technical solutions:
A kind of water heater hanger curved surface punching die is characterized in that: this mould comprises die, stripper, piercing punch, little guide pillar, compression spring, discharging screw, punch retainer, die shank and mould bases, and described mould bases is configured to by top mold frame and counterdie; The die that is used for placing stamping parts is arranged on down on the mould bases; The operative end surface shape and the stamping parts curve form of described piercing punch are suitable; Piercing punch is arranged on the top mold frame by punch retainer; Stripper is installed on the discharging screw and between die and piercing punch; The compression spring housing is contained on the discharging screw and between stripper and top mold frame; Die shank is connected with piercing punch; Being used for when piercing punch is descending the little guide pillar of restriction stripper traffic direction is arranged on the mould bases.
Among the present invention, adopt little matched in clearance between stripper and the piercing punch.Described compression spring is a rectangle compression spring.Between piercing punch and top mold frame, be provided with backing plate.
Little guide pillar in the utility model has guaranteed the upper and lower motion guide precision of stripper, and stripper is shielded to the die punching punch.
Gap during work between piercing punch and the die is even, thereby has guaranteed punching quality.
Curved surface punching die structure of the present utility model, compared with prior art, its advantage is: 1, the mould stripper has little guide pillar to do guiding; Stripper thickness increases; Reduced the gap between stripper and piercing punch; These have all strengthened the protection of stripper to piercing punch, have prolonged the service life of mould.2, at piercing punch with before workpiece contacts, stripper is with Work-sheet pressing, the piercing punch operative end surface is processed into the shape consistent with workpiece simultaneously, the mould punch is stressed steadily when guaranteeing punching.
The utility model is applicable to hole processing on curved surfaces such as various cambered surfaces, sphere, is specially adapted in the hole processing of water heater hanger.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is to use the water heater hanging rack structure schematic diagram of the utility model processing;
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment
A kind of water heater hanger curved surface punching die described in the utility model is seen Fig. 1, and it comprises die 1, stripper 2, piercing punch 3, little guide pillar 4, compression spring 5, discharging screw 6, punch retainer 7, die shank 8, mould bases 9 and backing plate 10.Mould bases 9 is made of top mold frame 91 and following mould bases 92; Die 1 is arranged on down on the mould bases 92; The operative end surface shape and the stamping parts curve form of piercing punch 3 are suitable; Piercing punch 3 is arranged on the top mold frame 91 by punch retainer 7; Stripper 2 is installed on the discharging screw 6 and between die 1 and piercing punch 3; Compression spring 5 is sleeved on the discharging screw 6 and between stripper 2 and top mold frame 91; Die shank 8 is connected with piercing punch 3; Be used for that the little guide pillar 4 of restriction stripper 2 traffic directions is arranged on the top mold frame 91 when piercing punch 3 is descending.Adopt little matched in clearance between stripper 2 and the piercing punch 3.Compression spring 5 is rectangle compression springs.Backing plate 10 is arranged on 91 of piercing punch 3 and top mold frame.
During work, stamping parts is by die 1 location, and top mold frame 91 is descending, at first by stripper 2 with Work-sheet pressing on die 1; Top mold frame 91 continues descending, and piercing punch 3 contacts with workpiece, and the hole is gone out.
In the utility model, according to the curved surface piercing punch characteristics that fracture easily, increase little guide pillar, improved the stripper guiding accuracy; Select the rectangle Compress Spring, strengthen pressure-plate-force, the mould punch is stressed steadily when guaranteeing punching. The utility model has improved the water heater hanger curved surface piercing punch life-span, has reduced production cost.
