Description

A composite mold for trimming and blanking

technical field

The utility model relates to the technical field of machinery, in particular to a trimming and blanking composite mold.

Background technique

In the current cold stamping process of sheet metal forming, most parts with complex structures and shapes still need to be produced by traditional single-sequence molds. Traditional single-sequence mold production uses more equipment and more operators, and the cost of stamping processing is higher. In order to reduce the cost of stamping, sequential dies are gradually used. The stamping production of combined dies reduces the number of parts produced, reduces the use of stamping equipment, and reduces stamping costs. However, in the production process of this sequential mold, the number of operators required by the original process is not saved, and the multi-manual operation also reduces the stamping production speed and increases safety hazards. Therefore, combined-sequence die stamping production only saves the use of stamping equipment, and does not fundamentally change the problems of low production efficiency and large labor cost of traditional single-sequence die stamping.

Therefore, it is necessary to design a trimming and blanking composite mold that can improve production efficiency and reduce labor costs.

In order to achieve the above-mentioned purpose, the utility model designs a compound mold for trimming and blanking, which includes an upper mold and a lower mold. Die blanking knife, the top of the lower mold base is fixed with a punch, the rear of the punch is fixed with a lower mold blanking knife, the rear side of the lower mold blanking knife is provided with a lower mold trimming knife, and the waste knife is fixed on the lower mold base The top of the lower mold edge trimming knife is located at the rear side of the lower mold. The left front side and the right front side of the lower mold blanking knife are respectively provided with the lower mold edge trimming knife two and the lower mold edge trimming knife three. The upper mold includes the upper mold seat, the concave Die, upper mold trimming knife and upper mold blanking knife, the bottom of the upper mold base is fixed with a die, the front of the die is fixed with an upper mold blanking knife, and the right and left front sides of the upper mold blanking knife are respectively equipped with Upper mold trimming knife one and upper mold trimming knife two, the rear of die is fixed with upper mold trimming knife three.

The lower mold base is fixed to the machine tool table of the pressing machine through the pressing plate.

The upper die base is fixed with the upper slide block of the machine tool of the pressing machine through the pressing plate.

The upper mold is matched with the lower mold.

Compared with the prior art, the utility model designs the structure of the trimming and blanking compound mold, and improves the traditional sequential mold that can only complete two or more processes of the same part in the same stroke Two processes of different parts are completed in the same stroke, and the trimming waste of one part is used as the blanking material of the other part, which improves stamping production efficiency, improves material utilization, reduces part cost, and saves mold tooling costs, reducing labor costs.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model is a kind of trimming blanking compound die, comprises upper die and lower die. The lower mold includes a lower mold base 1, a punch 2, a waste knife 3, a lower mold trimming knife and a lower mold blanking knife 9, the top of the lower mold base 1 is fixed with a punch 2, and the rear of the punch 2 is fixed with a lower mold Blanking knife 9, the rear side of lower mold blanking knife 9 is provided with lower mold edge trimming knife 6, and waste material knife 3 is fixed on the top of lower mold base 1 and is positioned at the rear side of lower mold edge trimming knife 6, and lower mold falls The left front side and the right front side of the material knife 9 are respectively provided with a lower mold trimming knife 2 7 and a lower mold trimming knife 3 8, and the upper mold includes an upper mold base 4, a die 5, an upper mold trimming knife and an upper mold blanking Cutter 13, the bottom of patrix seat 4 is fixed with die 5, and the place ahead of die 5 is fixed with patrix blanking knife 13, and the right front side and the left front side of patrix blanking knife 13 are provided with patrix trimming knife 1 respectively 10 and patrix trimming knife two 11, the rear of die 5 is fixed with patrix trimming knife three 12.

In the utility model, the upper die matches the lower die. The lower mold base 1 is the base for fixing the working parts and auxiliary parts, and the lower mold base 1 is fixed with the machine tool table of the press through the pressing plate to drive the working parts to work.

The punch 2 preliminarily locates the part process piece through the shape.

Waste knife 3 is used for cutting off waste material, makes waste discharge smooth and easy.

The trimming knife of the lower mold trims the outer contour of the part by cutting off the part, and separates the excess material, that is, the waste material, from the part body.

The blanking knife 9 of the lower mold obtains the blanking sheet by cutting off the part material, and the blanking sheet is the working raw material of the subsequent process.

The upper die base 4 is the base for fixing the working parts and auxiliary parts, and the upper die base 4 is fixed by the upper slide block of the machine tool of the pressing plate and the press to drive the working parts to work.

When the upper die moves downward, the die 5 presses the process part of the part to ensure the stable positioning of the process part.

The upper mold trimming knife trims the outer contour of the part by cutting off the part, and separates the excess material, that is, the waste material, from the part body.

Upper mold blanking knife 13 obtains blanking sheet by cutting off part material, and blanking sheet is the working raw material of subsequent process.
