Description

A stamping press with synchronous clamping function

technical field

The utility model relates to the stamping field, in particular to a stamping press with a synchronous clamping function.

Background technique

In the process of pressing down the existing stamping press, when the stamping rod contacts the workpiece, the workpiece is likely to be displaced along the line of action such as the punching force of the stamping rod. Therefore, how to avoid the displacement of the workpiece when the stamping rod contacts the workpiece is an urgent need. Solved the problem.

Utility model content

The utility model overcomes the deficiencies of the prior art and provides a stamping press with a synchronous clamping function, which tightens the workpiece from both sides at the moment when the stamping rod contacts the workpiece, avoiding the contact between the workpiece and the stamping rod Displacement occurs at the same time, and the displacement in the process of holding is also avoided, which improves the machining accuracy of this embodiment.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A stamping press with synchronous clamping function, which includes a stamping base, a support is provided on the stamping base, a stamping cylinder is provided on the upper end of the support, and a telescopic rod of the cylinder is connected with a stamping The stamping rod is provided with a wedge head, and the two wedge faces of the wedge head are connected with a symmetrical translation mechanism.

Furthermore, the translation mechanism includes a wedge, a rocker arm, and a positioning and reinforcing head. One end of the rocking arm is connected to the wedge, and the other end of the rocking arm is connected to the positioning and reinforcing head. The rocking arm and the bracket are connected through a fixed rod. connected, the rocker arm is hinged to the bracket.

Furthermore, a guide frame is arranged between the different supports, and the stamping rod passes through the guide frame.

Furthermore, a return spring is arranged between the two symmetrical translation mechanisms.

Compared with the prior art, the beneficial effect of the utility model is: the utility model tightens the workpiece from both sides at the moment when the stamping rod contacts the workpiece, which avoids the displacement of the workpiece when it contacts the stamping rod, and also avoids the The displacement that occurs during the clamping process improves the machining accuracy of the utility model.

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

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

The numbers in the figure are: 1. Stamping base; 2. Bracket; 3. Stamping cylinder; 4. Wedge head; 5. Stamping rod; 6. Fixing rod; 7. Wedge; 8. Rocker arm; 9. Positioning support 10, guide frame; 11, return spring.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described. Embodiments of the present utility model include but are not limited to the following examples.

[Example]

A stamping press with synchronous clamping function as shown in Figure 1, it comprises stamping base 1, described stamping base 1 is provided with support 2, and the upper end of described support 2 is provided with stamping cylinder 3, The telescoping rod of the cylinder 3 is connected with a stamping rod 5, and the punching rod 5 is provided with a wedge head 4, and both wedge faces of the wedge head 4 are connected with a symmetrical translation mechanism. The translation mechanism includes a wedge 7, a rocking arm 8, and a positioning clamping head 9. One end of the rocking arm 8 is connected to the wedge 7, and the other end of the rocking arm 8 is connected to the positioning clamping head 9. The rocking arm 8 is connected to the positioning clamping head 9. The bracket 2 is connected by a fixed rod 6, and the rocker arm 8 is hinged to the bracket 2. A guide frame 10 is arranged between the different supports 2 , and the stamping rod 5 passes through the guide frame 10 .

A return spring 11 is arranged between the two symmetrical translation mechanisms.

A stamping die is connected to the lower end of the stamping rod 5 .

Put the workpiece on the stamping base 1, adjust the position so that the workpiece is directly below the stamping die; then open the cylinder 3 to drive the stamping rod 5 to move downward, and the wedge head 4 also moves downward at the same time, and drives the wedge 7 to move to both sides And the spring is compressed by the rocker arm 8, and the positioning and clamping head 9 is driven to move to the workpiece, and the workpiece is tightened, so that the workpiece can be fixed while stamping. After the stamping work finished, the stamping rod 5 moved upwards, and the rocker arm 8 drove the positioning clamping head 9 to move on both sides under the action of the spring, so as to loosen the workpiece and facilitate the removal and placement of the workpiece.

The setting of the guide frame 10 avoids the deviation of the horizontal position of the stamping rod 5 during the moving process, and ensures the machining accuracy.

This embodiment has a simple structure and is easy to manufacture; in this embodiment, at the moment when the stamping rod contacts the workpiece, the workpiece is tightened from both sides at the same time, which avoids the displacement of the workpiece when it contacts the stamping rod, and also avoids the displacement during the clamping process. , which improves the machining accuracy of this embodiment.

The above is the embodiment of the present utility model. The utility model is not limited to the above-mentioned embodiment, anyone should know that the structural changes made under the enlightenment of the utility model, and any technical solutions that are the same as or similar to the utility model, all fall into the protection scope of the utility model within.
