Abstract

The utility model relates to a guide floating device for a material belt stamping die. The guide floating device comprises a lower die plate and a female die. The female die comprises a female die fixing plate and a female die base plate. The female die fixing plate is fixedly arranged on the upper surface of a lower die through the female die base plate, through grooves are vertically formed in the middle of the female die and the middle of the lower die plate in a penetrating mode, floating blocks are operated in the through grooves in a guiding mode, the number of the through grooves is two, the two floating blocks are located in the two through grooves in a one-to-one mode, the top of each floating block is exposed out of the upper surface of the female die, limiting grooves are formed in exposed parts in the radial direction, the two limiting grooves are located in a same horizontal line, and the bottom of each floating block is coaxially driven by a spring. The two ends of a material belt are supported by the two floating blocks, the floating effect of the material belt with the small size is guaranteed, the limiting grooves are symmetrically formed in the two floating blocks in the radial direction, the two ends of the floated material belt are located in the limiting grooves in the two sides of the material belt respectively, and then the material belt is more uniform and stable in the translation and guide process.

Description

A kind of buoyant of the guiding for material band stamping die device

Technical field

The utility model belongs to the diel field, the especially a kind of buoyant of the guiding for material band stamping die device.

Background technology

In the continuous punching process of material strip mould, for the ease of picking and placeing of material strip, usually be shaped with groove at the die middle part, in groove, the guiding operation has the buoyant device, and this buoyant device and diel traffic direction are in the same way, this buoyant device comprises a lift block, this lift block bottom, by a spring Driven by Coaxial, is equipped with the shutoff plug, for support spring in the die of spring bottom, also the shutoff plug can be taken off when adjusting and keep in repair simultaneously, groove is cleared up.

After being floated, material strip carries out the horizontally-guided operation, on the die surface of these buoyant piece both sides, symmetry is fixed with limited block respectively, but when the material strip size hour, guide pad and buoyant device all need to reduce size, but also can reduce the buoyant device and the material strip contact-making surface reduces, and guide pad and material strip process gap are too small, thereby cause guiding and buoyant weak effect, make the Speed Reduction of continuous punching, reduced production efficiency, production cost has raise.

Summary of the invention

The purpose of this utility model is to overcome the prior art deficiency, provide a kind of simple in structure, reasonable in design and comprehensive, to material strip adaptability the stronger buoyant of the guiding for material band stamping die device.

The technical solution adopted in the utility model is:

A kind of buoyant of the guiding for material band stamping die device, comprise lower bolster, die, die comprises die block and die backing plate, die block is packed in the counterdie upper surface by the die backing plate, vertically run through and be shaped with groove in the middle part of die and lower bolster, in this groove, the guiding operation has lift block, described groove is two, described lift block be two and one by one correspondence be positioned at two grooves, die upper surface and the equal radial system limited location of exposed portions serve groove are all exposed in each lift block top, two stopper slots are positioned at the same level line, each lift block bottom is respectively by a spring Driven by Coaxial.

And, in the lower bolster of described each spring bottom, the shutoff plug all is installed.

And the distance between the size of described each lift block and two lift blocks should be carried out Matching and modification according to the material strip physical length.

Advantage and good effect that the utility model adopts are:

The utility model effective integration existing guide pad and buoyant device workpiece used, by two lift blocks, the material strip two ends are supported, guaranteed the buoyance lift effect of the material strip less to size, and on two lift blocks symmetrical radial system limited location groove, make the material strip two ends after buoyance lift lay respectively at its both sides in stopper slot, while making its guided in translation, more evenly with steady, thereby improved drawing velocity, production efficiency is improved, reduced production cost.

The accompanying drawing explanation:

Fig. 1 is the structural representation (axis is analysed and observe) of die and lower bolster in the utility model;

Fig. 2 is the status architecture schematic diagram (omission punch) when in the utility model, die is extruded.

The specific embodiment:

Below by drawings and the specific embodiments, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of buoyant of the guiding for material band stamping die device, see Fig. 1, comprise lower bolster 6, die, die comprises die block 1 and die backing plate 5, die block is packed in the counterdie upper surface by the die backing plate, vertically run through and be shaped with groove in the middle part of die and lower bolster, in this groove, the guiding operation has lift block 2.

Innovative point of the present utility model is:

Described groove is two, described lift block be two and one by one correspondence be positioned at two grooves, die upper surface and the equal radial system limited location of exposed portions serve groove 4 are all exposed in each lift block top, two stopper slots are positioned at the same level line, each lift block bottom is respectively by spring 7 Driven by Coaxial, see Fig. 2, at two lift blocks after extruding downwards, between two stopper slots and die upper surface, material strip 3 is placed in space, after the lift block floating, material strip floats and lays respectively at by two ends in the stopper slot of two lift blocks with lift block, is convenient to its guided in translation.

In the lower bolster of each spring bottom, shutoff plug 8 all is installed.

In the present embodiment and in accompanying drawing, omit punch and patrix, be convenient to thus more clearly illustrate the present utility model point.

Distance between the size of each lift block and two lift blocks should be carried out Matching and modification according to the material strip physical length.
