Description

Electric self-moving clamp

Technical Field

The utility model relates to the technical field of clamping devices, in particular to an electric self-moving type clamping device.

Background

At present, the rapid die change is more and more widely applied to automatic stamping production workshops, and in order to realize the automatic die change function, the used clamping device needs to be mutually matched with a pressing machine, a die change trolley and a push-pull mechanism, so that the full-automatic die change work is realized. Therefore, the clamping device has two functions of clamping and loosening, and also has the function of automatically advancing and retreating and being capable of automatically moving according to the mold changing logic and the mold position.

The self-moving type clamping device used in the market at present is connected with an air cylinder through the clamping device, and compressed air enters from an advancing air inlet and a retreating air inlet of the air cylinder through the reversing of an electromagnetic valve, so that the advancing and retreating functions of the clamping device are realized. The detailed structure is shown in figure 6

Description of the operation process:

the mold changing action process is that when the mold needs to be changed, the clamping device is loosened, the mold is pulled out from the press to the mold changing trolley by the push-pull mechanism, the mold changing trolley moves, the mold to be changed in another station is conveyed to the working table of the press through the push-pull mechanism, the air cylinder pushes the clamping device to the position needing to be clamped, the clamping device clamps the mold, then the press starts to work, and the mold changing is completed.

The working action process of the clamping device is that when the loosening signal is received, the pump station stops supplying oil. The clamp pushes a piston under the action of a spring, and the piston drives a T-shaped rod to move, so that the clamp releases a die. Compressed air enters from the air cylinder IV through a backward air inlet, the piston rod of the air cylinder drives the clamping device to move backwards, and the backward detection approach switch stops moving after detecting the initial position. When a clamping signal is received, compressed air enters from an advancing air inlet of the air cylinder, a piston of the air cylinder pushes the clamping device to move forwards, and an advancing detection proximity switch detects that the air cylinder stops moving after the mold. When the pump station starts to work and supplies oil, high-pressure oil enters the oil cylinder of the clamping device to push the piston and the T-shaped rod, so that the die and the T-shaped groove are clamped. For details, see figure 2

The cylinder-driven self-moving clamp can meet part of use scenes, but has the problems of several disadvantages:

first, the use scenario is limited, and when the moving stroke of the clamping device is too large, the protruding amount of the whole device is too large due to the principle and the structure of the air cylinder, so that the grating detection of the edge of the working table of the press is influenced.

Secondly, the structure safety is not high, and the transmission device is completely exposed outside and has no corresponding protection measures.

And thirdly, when each press is matched with a plurality of clamping devices, the action uniformity of the clamping devices is poor, and the clamping devices cannot be controlled to be in place simultaneously due to the fact that the movement depends on compressed air transmission, so that the die change time is prolonged.

Any of the above problems may affect the generation of problems of the mold changing system, so that structural improvement of the cylinder push type clamp is necessary according to the use occasion of the clamp, and the problems are avoided.
