In order to achieve the above purpose, the utility model provides a switchable insert trial-manufacturing die, which comprises a male die, a female die, a blank holder and an insert, wherein the insert comprises a drawing insert and a shaping insert, the top of the drawing insert is matched with the pre-shaping shape of a product, and the top of the shaping insert is matched with the final shape of the product; the edge pressing ring is internally provided with a male die, the shaping side of the male die is symmetrically provided with a notch groove, and a drawing insert or a shaping insert is arranged in the notch groove.

Further, the insert is fixed at the notch of the male die through a plurality of screws and pins.

Further, the inner side shape of the insert is matched with the parting boundary shape.

Further, the bottom of the male die is provided with an inwardly extending U-shaped groove, and a bolt penetrates through the U-shaped groove to fix the male die on a press machine tool.

Furthermore, three outer edges of the blank holder are provided with positioning pins for limiting the product to be shaped.

Further, the blank holder is connected with the male die through the sliding guide surface.

Furthermore, the male die is provided with fixing holes corresponding to the screws and the pins.

Furthermore, lifting lugs are symmetrically arranged on the outer side of the blank holder.

As a further feature, the bead ring is supported by a plurality of ejector pins on the press machine.

Further, pressing plates are symmetrically arranged on the outer sides of the female dies, and the female dies are fixed on sliding blocks of the pressing machine through the pressing plates.

Compared with the prior art, the technical scheme adopted by the utility model has the advantages that: according to the utility model, two sets of tooling dies are changed into one set by switching the insert, so that the number of die sets, the processing area and the die grinding and debugging time are reduced, the labor is saved, and the production efficiency is improved; as only the insert changes in the two shaping processes and other areas are consistent, the defect of inconsistent shaping is avoided, the flatness of the dough product is ensured, and the product quality is stable.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the particular embodiments described herein are illustrative only and are not intended to limit the utility model, i.e., the embodiments described are merely some, but not all, of the embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.

Example 1

As shown in fig. 1-4, the embodiment provides a switchable insert trial-manufacturing die which is specially used for trial-manufacturing drawing and shaping, and mainly comprises a male die, a female die, a blank holder and an insert, wherein the insert comprises a drawing insert and a shaping insert, and the drawing insert and the shaping insert are fixed at a notch groove of the male die through a plurality of screws and pins; the male die is positioned in the blank holder, and a plurality of positioning pins are arranged on the periphery of the flattening part of the product area and used for limiting the product to be shaped; the bottom of the male die is provided with a U-shaped groove extending inwards, and a bolt penetrates through the U-shaped groove to fix the male die on a press machine tool; pressing plates are symmetrically arranged on the outer sides of the female dies, and the female dies are fixed on sliding blocks of the pressing machine through the pressing plates.

The working process of the die is as follows: the drawing insert is arranged at two notch grooves of the male die through screws and pins, the female die is driven to move downwards through a sliding block of the press and is closed with the male die, and drawing and shaping of a local area are achieved; and then the sliding block drives the female die to retract to the upper starting point. The drawing insert is detached and replaced by the shaping insert by screwing down the screw and the pin, the shaping insert is installed at two notch grooves of the male die by screwing down the screw and the pin, the female die is driven to move downwards by the sliding block of the press to be closed with the male die, and at the moment, the secondary shaping of the trial-produced products is realized.

Because the two-sequence die for trial-manufacture drawing shaping has a large overlapping area, the utility model adds the switchable insert on the male die, and completes two-sequence different shaping work by switching the insert on the premise of ensuring that the male die, the female die and the blank holder are unchanged. The method improves the product quality, reduces the number of dies and personnel, and ensures the stability of the product quality.

The foregoing descriptions of specific exemplary embodiments of the present utility model are presented for purposes of illustration and description. It is not intended to limit the utility model to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching.
