Description

Forming elbow bending die

Technical field

The utility model makes the auxiliary equipment of bend pipe, particularly a kind of forming elbow bending die that can improve forming elbow quality.

Background technology

At present, in iron art furnishings product, the bend pipe structure of various shape can often be used, such as tea table leg etc.The molding mode of bend pipe has multiple, is generally come by the mould coordinated up and down on pressing equipment for more regular bend pipe structure.Mould is made up of upper die component and lower mold assemblies, upper die component is made up of cope match-plate pattern and the upper male mould being fixed on its lower end, lower mold assemblies has the lower cavity die of lower bolster and end fixed thereon to form, the lower surface of upper male mould and the upper surface of lower cavity die are the arcuate structure matched, and this arcuate structure is consistent with the bending shape of tubing.Adopt the mould of this structure to bend to tubing, need tubing to be bent to be placed on lower cavity die, then patrix is descending, is applied to the downward impulsive force of tubing, is bent by tubing.This impact being applied to tubing is larger rigid shock, causes patrix to the comparatively large Forming Quality with ensureing bend pipe of tubing impulsive force.

Summary of the invention

The utility model provides a kind of patrix that reduces to the impulsive force of tubing, the forming elbow bending die improving forming elbow quality for solving in known technology the technical problem that exists.

The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:

Forming elbow bending die, comprise upper die component and lower mold assemblies, described upper die component is made up of cope match-plate pattern and the upper male mould being fixed on its lower end, the lower cavity die that described lower mold assemblies comprises lower bolster and end disposed thereon is formed, upper male mould and lower cavity die align up and down, and on both faying faces, be provided with the locating slot fixed for realizing tubing, it is characterized in that: along the arc length direction of lower cavity die upper surface, described lower cavity die is made up of with the active module being arranged on middle part the stuck-module being arranged on two ends, the stuck-module at described two ends is fixed on lower bolster, described active module is positioned at the low ebb position of lower cavity die cambered surface, several lead is fixed with in the lower end of active module, lower bolster is provided with respectively for the guide through hole that each lead passes, the elasticity penetrating mechanism that can realize active module is lifted is installed in the lower end of lower bolster.

The utility model can also adopt following technical measures:

Described elasticity penetrating mechanism comprises central shaft, the upper end of central shaft is fixedly connected with lower bolster, the spring being provided with block plate, lower block plate on center shaft and being arranged between two block plates, the upper surface of upper block plate and the lower surface of several lead compress, on the position of lower end, be threaded connection nut at central shaft, described nut is pressed on the lower surface of lower block plate.

The advantage that the utility model has and good effect are:

Adopt this bending die, tubing to be formed is placed in after on active module, in the process that upper die component is descending, first upper male mould contacts with active module and compresses, tubing is stuck in the locating slot formed between upper module and active module, then, drive tubing descending together, realize the bent into shape of tubing.This bending die is compared to existing bending die, in the process of bending, first by upper male mould and active module, tubing is blocked, and continue in descending process at patrix, by the effect of the elasticity penetrating mechanism of lower end, make descending process be subject to cushion effect, such patrix is applied to the flexible impact of tubing one, thus reduce the impulsive force of patrix to tubing, tubing is deformed gradually, and then also improves the Forming Quality of bend pipe.

Detailed description of the invention

For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1 and 2, forming elbow bending die, comprise upper die component 1 and lower mold assemblies 2.Described upper die component is made up of cope match-plate pattern 110 and the upper male mould 120 being fixed on its lower end.Cope match-plate pattern can adopt slab construction, and upper male mould can adopt bending plate, and cope match-plate pattern and upper male mould are welded together by the multiple vertical contiguous block arranged between the two.The lower cavity die 220 that lower mold assemblies comprises lower bolster 210 and end disposed thereon is formed.Upper male mould and lower cavity die align up and down, both faying faces are provided with the locating slot fixed for realizing tubing, namely the lower surface of upper male mould and the upper surface of lower cavity die are respectively equipped with one and half grooves, the split of two halves groove forms described locating slot, and the cross section of this locating slot is consistent with the cross section of tubing to be formed.Along the arc length direction of lower cavity die upper surface, described lower cavity die is made up of with the active module 222 being arranged on middle part the stuck-module 221 being arranged on two ends.The stuck-module at described two ends is fixed on lower bolster, and described active module is positioned at the low ebb position of lower cavity die cambered surface, and namely along the arc length direction of lower cavity die upper surface, this active module is positioned at the extreme lower position of cambered surface.Be fixed with several lead 223 in the lower end of active module, lower bolster be provided with respectively for the guide through hole that each lead passes.The elasticity penetrating mechanism 3 that can realize active module is lifted is installed in the lower end of lower bolster.

In said structure, described elasticity penetrating mechanism comprises central shaft 310, the upper end of central shaft is fixedly connected with by screw thread or other mode with lower bolster, the spring 340 being provided with block plate 320, lower block plate 330 on center shaft and being arranged between two block plates, the lower surface of the upper surface of upper block plate and several leads of active module lower end compresses, on the position of lower end, be threaded connection nut 350 at central shaft, described nut is pressed on the lower surface of lower block plate.Adopt this elasticity penetrating mechanism, when upper die component is in top dead center position, under the action of the spring, upper block plate is pressed on the lower surface of lower bolster, now, active module is at the highest notch position, when the descending certain distance of upper die component, first contacts with active module, active module is applied to the downward thrust of upper block plate by the multiple leads being located at lower end, under the effect of this thrust, upper block plate moves down, and spring is gradually reduced; When lower surface and the upper surface of lower cavity die two ends stuck-module of upper male mould compress completely contact time, active module moves to position bottom, and now, the stuck-module at two ends and the active module at middle part are spliced to form a complete arc surface; After upper male mould and lower cavity die have compressed the bent into shape of a tubing, upper die component is up, now, under the elastic force effect of spring, and the active module distance that also uplink synchronization is certain.

The mentality of designing of this bending die had both been applicable to the bent into shape of single bend pipe bending, namely had the bent into shape of the bend pipe of a low ebb, was also applicable to the bent into shape of many bend pipe bendings, namely had the bent into shape of the bend pipe of multiple low ebb.When the bend pipe that will process is many bend pipe bendings, except upper male mould needs to adopt corresponding arc shape, the elasticity penetrating mechanism that the position that lower cavity die corresponds to each low ebb all arranges an active module and matches.
