Description

A stamping and bending die

technical field

The utility model relates to a stamping and bending die, which belongs to the field of stamping dies.

Background technique

The bending die is a tool used by the bending machine to form and process the sheet metal. This tool is composed of various parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. A tool used to turn a blank into a workpiece of a specific shape and size under the pressure of a bending machine. At present, most of the bending dies on the market use the cooperation of the upper die and the lower die to bend the material, but in this way, the material can only be bent once, and the upper and lower directions cannot be bent at the same time. low efficiency.

Utility model content

The technical problem to be solved by the utility model is: to provide a stamping and bending die, which solves the problem of low efficiency caused by a bending die in the market that can only be bent once for one stamping.

The technical problem to be solved by the utility model is realized by taking the following technical solutions:

A stamping and bending mold, which includes an upper template, a base, an upper mold fixed to the upper template, a lower mold fixed to the base, and a bending mechanism including a movable mold, a transmission rod, a bracket, a connecting One side of the lower mold is provided with a vertical chute, the movable mold is arranged in the chute, the middle part of the transmission rod is fixed on the base through a bracket, and the two ends of the transmission rod are respectively connected with the movable mold and the spring. The rods are connected, and the connecting rods are connected with the upper formwork through springs.

As a preferred example, the middle part of the transmission rod is provided with a first long hole, which is connected with the bracket through a pin shaft.

As a preferred example, one end of the transmission rod is provided with a second long hole, which is connected with the connecting rod through a pin shaft.

The beneficial effects of the utility model are: through the mutual cooperation between the upper die, the lower die and the movable die, one stamping can perform two bendings, which improves the bending efficiency and bending quality. The utility model has the advantages of simple structure, low cost and convenient installation.

Description of drawings

Fig. 1 is the structural representation of the utility model.

In the figure: upper template 1, base 2, upper mold 3, lower mold 4, movable mold 5, transmission rod 6, bracket 7, connecting rod 8, spring 9, chute 41, first long hole 61, second long hole 62.

Detailed ways

In order to be easy to understand the technical means, creative features, goals and effects of the utility model, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1, a stamping and bending die includes an upper template 1, a base 2, an upper mold 3 fixed to the upper template 1, a lower mold 4 fixed to the base 2, and a bending mechanism. Including movable mold 5, transmission rod 6, bracket 7, connecting rod 8, spring 9, vertical chute 41 is provided on one side of lower mold 4, movable mold 5 is set in chute 41, and the middle part of transmission rod 6 is fixed by bracket 7 On the base 2, and the two ends of the transmission rod 6 are respectively connected with the movable mold 5 and the connecting rod 8, and the connecting rod 8 is connected with the upper template 1 through a spring 9. The middle part of the transmission rod 6 is provided with a first long hole 61, which is connected with the bracket 7 through a pin shaft. One end of the transmission rod 6 is provided with a second long hole 62, which is connected with the connecting rod 8 through a pin shaft.

For materials that need to be bent twice, the upper mold 1 drives the upper mold 3 to move downward, cooperates with the lower mold 4 to perform the first bending, the upper mold 1 continues to move downward, and is driven by the connecting rod 8 and the transmission rod 6. Die 5 moves upwards for the second bending. Through the mutual cooperation among the upper die 3, the lower die 4 and the movable die 5, one stamping can perform two bendings, which improves the bending efficiency, has simple structure, low cost and convenient installation.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. On the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes and improvements, and these changes and improvements all fall into the Into the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
