Description

Quartering punching device

Technical Field

The utility model relates to a stamping process technical field especially relates to a quartering punching device.

Background

The stamping process is a production technology for obtaining product parts with certain shape, size and performance by directly applying deformation force to a plate in a die by means of the power of conventional or special stamping equipment and deforming the plate.

At present, the punching device is generally applied to a flat plate, and rectangular array type punching is carried out, so that the punching of a cylindrical shape or a three-dimensional shape is very inconvenient.

Disclosure of Invention

According to the technical problem to be solved, the quartering punching device is provided.

In order to achieve the purpose, the utility model discloses a quartering punching device, including placing the platform, it is equipped with the fixing base respectively to place a mesa quartering position, what the fixing base surrounded places a center department and is equipped with the fixed mould, connect the cylinder in the fixing base respectively, the flexible end of cylinder passes the fixing base preformed hole to the stamping knife is connected on the top, the fixed mould all is equipped with the through hole for stamping knife department.

Further, the fixed die is fixed to a placing table by bolts, and is divided into an inner layer and an outer layer.

Furthermore, the inner layer is cylindrical, the outer layer is rectangular, and an annular gap of 0.3-0.8mm is reserved between the inner layer and the outer layer.

Still further, the annular gap is 0.3 mm.

Further, the inner and outer layers of the fixed mold are provided with vertical through holes in planes and are staggered with the through holes on the four sides of the fixed mold.

Furthermore, pressing blocks are arranged at the joints of the stamping knife and the telescopic end of the air cylinder, and through holes are formed in the centers of the pressing blocks and penetrate through the stamping knife.

Has the advantages that: the quartering punching device of the utility model has high punching efficiency for the three-dimensional parts; more accurate than manual equal division; is suitable for various three-dimensional parts.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a top view of the present invention.

In the figure: 2 is a punching knife; 3, pressing blocks; 4 is a fixed seat; 5 is a cylinder; 6 is a placing table; and 7 is a fixed mould.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the present invention.

As shown in fig. 1 and 2, the quartering punching device comprises a placing table, wherein fixing seats 4 are respectively arranged on four equal parts of a table top of the placing table 6, a fixed mold 7 is arranged at the center of the placing table 6 surrounded by the fixing seats 4, air cylinders 5 are respectively connected in the fixing seats 4, telescopic ends of the air cylinders 5 penetrate through preformed holes of the fixing seats 4, the top ends of the air cylinders are connected with punching knives 2, and the fixing molds 7 are respectively provided with through holes corresponding to the punching knives 2.

Wherein, firstly, the fixed mould 7 is fixed at the center of the placing table 6, then the material is sleeved in the gap of the inner layer and the outer layer of the fixed mould 7, the equant cylinder 5 is pushed and the material is penetrated by the punch 2, cooling liquid can be added in the penetrating hole before punching, and the placed material is damaged by overheating.

As shown in fig. 1 and 2, the fixed die 7 is fixed to the placing table 6 by bolts, and is divided into an inner layer and an outer layer.

In this case, the fixed die 7 can be replaced according to actual conditions, and is not only single-size machining.

As shown in figures 1 and 2, the inner layer is cylindrical, the outer layer is rectangular, and an annular gap of 0.3-0.8mm is reserved between the inner layer and the outer layer.

As shown in fig. 1 and 2, the annular gap is 0.3 mm.

Wherein, the clearance is left to inlayer and skin for insert the clearance with the material and fix, and the size in clearance selects for use according to the material wall thickness of processing, and outer rectangle department also can registrate the rectangle material and process.

As shown in FIGS. 1 and 2, the fixed mold 7 is provided with vertical through holes in the inner and outer planes, and is staggered with the through holes in the four sides of the fixed mold 7.

Wherein, set up vertical through-hole for adding the coolant liquid, prevent that the high temperature damages the material in stamping process.

As shown in fig. 1 and 2, pressing blocks 3 are arranged at the joints of the punching knife 2 and the telescopic ends of the air cylinders 5, and through holes are arranged at the centers of the pressing blocks 3 and penetrate through the punching knife 2.

During the punching process, when the telescopic end of the cylinder 5 extends out for a certain length, the pressing block 3 is abutted against the outer layer of the fixed die 7, and the cylinder 5 retracts to prevent the punching knife 2 from being damaged.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The above examples are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention, and all designs identical or similar to the present invention are within the scope of the present invention.
