Further, it also includes a balance bar, the balance bar is fixed on the second connection end of the connecting rod, after the balance bar is installed on the second connection end of the connecting rod, when the tool needs to be pressed, it will be squeezed by the balance bar The tool can increase the contact area with the tool, so as to better fix the tool.

Further, a buffer pad is also included, and the buffer pad is installed on the balance bar, and a layer of buffer pad is arranged on the balance bar to reduce the risk of crushing the tool when the tool is squeezed.

Further, the buffer pad is made of polyurethane material, and other suitable materials can also be selected according to the actual situation.

Further, the cross-sectional shape of the base is L-shaped, specifically an inverted L-shape, and the cylinder base is installed on the long side of the base, and the connecting rod base is installed on the short side of the base.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

The quick-change tooling for bending knives of the flanging machine of the utility model can be independently installed on the flanging machine, and can be used in a single group or in combination with multiple sets of tooling according to production needs. The scimitar is fixed on the tool holder, which can effectively improve the efficiency of installing and replacing the tool during production, thereby greatly improving production efficiency, and has the advantages of simple structure, low manufacturing cost, quick and convenient installation, easy maintenance, low failure rate, simple operation, Features such as strong versatility.

Detailed ways

Below in conjunction with embodiment the utility model is described in further detail:

Example

As shown in FIG. 1 , a quick-change tooling for bending knives of a flanging machine includes a base 10 , a cylinder 8 , a cylinder seat 9 and a connecting rod assembly.

The cylinder base 9 is fixed on one end of the base 10 , the cylinder 8 is installed on the cylinder base 9 , and the push block 1 is installed on the telescopic rod 81 of the cylinder 8 .

The connecting rod assembly is composed of a connecting rod 2 and a connecting rod seat 3, the connecting rod seat 3 is fixed on the other end of the base 10, the connecting rod 2 is movably connected to the connecting rod seat 3, and the two ends of the connecting rod 2 are respectively the first connecting ends 21 and the second connection end 22, and the first connection end 21 of the connecting rod 2 is fixedly connected with the push block 1 .

Wherein, the shape of the base 10 in this embodiment is L-shaped, specifically an inverted L-shape, and the cylinder base 9 is installed on the long side of the base 10 , and the connecting rod base 3 is installed on the short side of the base 10 .

A balance bar 5 is installed on the second connecting end 22 of the connecting rod 2, and a layer of buffer pad 6 for contacting the tool is arranged on the balance bar 5, and a layer of buffer pad 6 is added between the balance bar 5 and the tool, which can reduce the Risk of crushing or scratching the knife when squeezing it.

As a preference, the buffer pad 6 in this embodiment is made of polyurethane material, and other suitable materials can also be selected according to the actual situation.
