Description

A suspended stamping tooling assembly

technical field

The invention relates to a suspended stamping tool assembly.

Background technique

At present, in stamping operations, in order to realize the automation of stamping operations, tooling dies are usually set on the turntable or slide table to realize continuous stamping operations, but the tooling dies are fixed on the turntable or slide table. At this time, the turntable or slide table directly bears the stamping force, which can easily cause damage to the turntable or slide table, reduce the service life of the turntable or slide table, and increase the cost of use and maintenance.

In order to overcome the deficiencies of the prior art, the invention provides a suspended stamping tool assembly.

The technical solution adopted by the present invention to solve its technical problems is:

A suspended stamping tooling assembly, comprising a workbench, a supporting platform arranged on the working platform, an upper tooling mold for placing required stamping workpieces and a lower tooling mold arranged on the stamping equipment, the supporting platform is There are several stations, and the upper tooling mold is set on the station through an elastic suspension mechanism, so that there is a distance from the bottom of the upper tooling mold to the workbench. When the upper tooling mold is stamped by the stamping equipment, the upper tooling mold Move down until it rests on the table to complete the punching operation.

The elastic suspension mechanism includes a tooling base plate arranged between the workbench and the supporting platform, and the tooling base plate is suspended on the working position of the supporting platform through a tension spring.

A limit sleeve is arranged on the bottom plate of the tooling, a guide rod is provided on the limit sleeve, a guide hole matched with the guide rod is provided on the upper tooling mold, and a buffer device is arranged between the tooling bottom plate and the upper tooling mold .

The buffer device includes a slide bar arranged between the bottom plate of the tooling and the upper tooling mold and a spring sleeved on the slide bar.

A positioning device is also arranged between the lower tooling mold and the upper tooling mold.

The positioning device includes a positioning pin arranged on the lower tooling mold and a positioning hole arranged on the upper tooling mold to cooperate with the positioning pin.

The support platform is a turntable.

The beneficial effects of the present invention are: a suspended stamping tool assembly, including a workbench, a supporting platform such as a turntable or a sliding platform arranged on the workbench, an upper tooling mold for placing the required stamping workpiece, and a tooling mold arranged on the stamping equipment. For the upper and lower tooling moulds, several stations are set on the supporting platform, and the upper tooling mold is set on the stations through an elastic suspension mechanism, so that there is a distance between the bottom of the upper tooling mold and the workbench. When the upper tooling die is stamped by the stamping equipment, the upper tooling die moves down until it abuts against the workbench before completing the stamping operation, so that the workbench bears the stamping force, while the supporting table only needs to bear the force of hanging the upper tooling die, avoiding bearing damage to the pallet, prolong its service life, reduce use and maintenance costs, and correct the position of the upper tooling mold by setting a positioning mechanism such as a positioning pin between the upper tooling mold and the lower tooling mold, so that the upper tooling mold and the lower tooling mold The matching precision is higher, the precision of stamping is improved, the requirements for the rotation or sliding precision of the supporting table are reduced, and the difficulty of production is reduced.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is a structural representation of the present invention;

Figure 2 is an exploded schematic diagram of the mold part of the upper tooling of the present invention.
