Description

Stamping die device capable of replacing different stamping shapes

Technical Field

The invention relates to the technical field of die stamping, in particular to a stamping die device with replaceable different stamping shapes.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping, and is called a cold stamping die (commonly called a cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

Die stamping is a press working method for obtaining a required part by applying pressure to a material at room temperature by using a die mounted on a press to cause separation or plastic deformation, and the existing die stamping device basically meets people's needs, but still has some problems in the using process.

Although the existing die stamping device has a simple fixing structure, the fixing mode is single, only a die in one shape and size can be fixed, the stamping dies in different shapes cannot be replaced, and the requirements of people cannot be met.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a stamping die device with replaceable different stamping shapes.

The invention is realized by the following technical scheme:

the invention provides a stamping die device capable of replacing different stamping shapes, which comprises a die stamping device main body, wherein a stamping platform is arranged on the die stamping device main body, two opposite sides of the stamping platform are respectively fixed with a fixed seat, a driving rod is rotatably connected between the two fixed seats, one end of the driving rod penetrates through one of the fixed seats and is fixed with a handle, external threads with opposite rotating directions are arranged at the positions, close to the two ends, of the driving rod, two clamping seats are slidably connected between the two fixed seats, the two clamping seats are correspondingly and spirally connected with the positions, close to the two ends, of the driving rod, one sides, opposite to the two clamping seats, are positioned above the driving rod and are symmetrically provided with clamping grooves, and the peripheral inner walls of the clamping grooves are step-shaped.

Preferably, both ends of the driving rod are correspondingly and rotatably connected with the two fixing seats through bearings.

Preferably, the two clamping seats correspond to the inner thread through holes matched with the outer threads of the driving rod close to the two ends of the driving rod.

The invention has the beneficial effects that: the invention is convenient for replacing dies with different sizes, meets various use requirements, and strengthens the application range of the stamping device.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a stamping die apparatus capable of replacing different stamping shapes according to an embodiment of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a stamping die device capable of changing different stamping shapes, the stamping die device capable of changing different stamping shapes includes a die stamping device main body 1, a stamping platform 2 is disposed on the die stamping device main body 1, and an upper die is driven by a hydraulic device to move up and down on the die stamping device main body 1 above the stamping platform 2.

Referring to fig. 2, fig. 2 is a schematic top view of a stamping platform according to an embodiment of the present invention.

As shown in fig. 2, two opposite sides of the stamping platform 2 are respectively fixed with a fixing base 3, a driving rod 4 is rotatably connected between the two fixing bases 3, two ends of the driving rod 4 are rotatably connected with the two fixing bases 3 correspondingly through bearings, the bearings are fixedly embedded in the fixing bases 3, and the end portions of the driving rod 4 are fixedly inserted into inner rings of the bearings.

Continuing to refer to fig. 2, one end of the driving rod 4 penetrates through one of the fixing seats 3 and is fixed with a handle 5, the driving rod 4 is driven to rotate by the handle 5, the driving rod 4 is provided with external threads with opposite rotation directions near two ends, two clamping seats 6 are further connected between the two fixing seats 3 in a sliding manner, the two clamping seats 6 are rectangular seats, and the bottom ends of the two clamping seats are in sliding contact with the surface of the stamping platform 2.

The two clamping seats 6 are in corresponding spiral connection with the driving rod 4 close to two ends. Specifically, the two clamping seats 6 correspond to the internal thread through holes matched with the external threads of the driving rod 4 close to the two ends.

In addition, the opposite sides of the two clamping seats 6 are symmetrically provided with clamping grooves 7 above the driving rod 4, the inner walls of the peripheries of the clamping grooves 7 are step-shaped, and the clamping grooves 7 which are step-shaped can relatively clamp lower dies with different sizes to match with the upper die to complete stamping.
