Description

Blanking die for disc workpiece

technical field

The utility model relates to a stamping die. Specifically, it is a blanking die used to stamp the initial disc-shaped workpiece during the manufacturing process of the cup-shaped cylinder block on the right-angle valve.

Background technique

At present, in the machining industry, the method used to manufacture the upper cup-shaped cylinder block of the right-angle valve is mainly the casting method, that is, the cup-shaped lower mold and the cylindrical upper mold are used to pour the molten metal into the cup-shaped lower mold. The cylindrical upper mold enters the cup-shaped lower mold, thereby casting the molten metal into a cup-shaped workpiece blank. Then, the metal blank is cut to make the required cup-shaped workpiece. Since the casting method needs to be equipped with a melting furnace to smelt the metal, the energy consumption is high and the production cost is high. And because the casting method requires the impurity content of the molten metal to be particularly low, otherwise, air bubbles are likely to appear in the cast workpiece. Therefore, the quality of the cylinder block produced by the casting method is poor, and the reject rate is high.

Utility model content

The problem to be solved by the utility model is to provide a blanking die for a disc-shaped workpiece. The workpiece stamped by the blanking die of the disc-shaped workpiece can be made into a cup-shaped cylinder body through subsequent stamping operations. The whole operation process consumes less energy and the production cost is low. Moreover, the workpiece produced by this mold has good quality and low scrap rate.

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

The blanking die of the disc-shaped workpiece of the utility model is characterized in that it includes an upper base plate and a lower base plate, guide holes are arranged at corresponding positions on both sides of the upper and lower base plates, and a guide column is arranged in each corresponding pair of guide holes. The guide column is fixedly connected with the lower base plate, and the guide column is slidingly fitted with the upper base plate. A punching die is fixed above the lower bottom plate, and a round hole is arranged on the punching die. A punch is fixed below the upper bottom plate, the punch is cylindrical and the diameter is equal to the diameter of the hole on the die, and the punch is concentric with the hole on the die.

A further improvement of the utility model is that there is a rubber in the round hole of the punching die, and a disc-shaped first top plate is arranged above the rubber, and the diameter of the first top plate is equal to the diameter of the round hole on the punching die. The thickness of the die is equal to the thickness of the rubber plus the thickness of the first top plate. In this way, it is beneficial to take out the disc-shaped workpiece in the circular hole of the punching die very conveniently after the stamping operation is completed.

A further improvement of the utility model is that the outside of the punch is covered with a rubber ring and an annular second top plate from top to bottom, and the thickness of the punch is equal to the thickness of the rubber ring plus the thickness of the second top plate. In this way, it is beneficial to easily remove the plate residue covered on the punch after the stamping operation is completed.

Adopting the above scheme has the following advantages:

It can be seen from the above scheme that the disc-shaped workpiece blanking mold of the present invention can provide the required initial workpiece for the subsequent operation of the cup-shaped cylinder block. Compared with the traditional casting method, it does not need a furnace, consumes less energy, and can reduce manufacturing cost. Because the utility model adopts the punch head, punching die and stamping machine to stamp the metal plate into a disc-shaped workpiece, the quality of the metal plate determines the quality of the workpiece. As long as a better plate such as a stainless steel plate is selected, the quality of the workpiece can be guaranteed. . Therefore, compared with the background technology, the occurrence of air bubbles in the workpiece can be avoided, the quality of the workpiece can be ensured, and the rejection rate of the workpiece can be greatly reduced.
