Embodiment Construction

[0023] Combine below figure 2 , the present invention is further described:

[0024] A mold comprising a mandrel 3, an integral upper die 1 and an integral lower die 2, the integral upper die 1 is composed of a basic upper die 11 and a quick-change upper die 12, the basic upper die 11 is fixedly connected to the main oil cylinder of a machine tool, The quick-change upper die 12 presses down on the upper surface of the workpiece 5. The quick-change upper die 12 is a detachable and replaceable structure. The basic upper die 11 and the quick-change upper die 12 are fixed by fixing bolts; The lower die 21 and the quick change die 22 are combined. The basic lower die 21 is fixedly connected with the machine tool. Lower die 21 and fast change die 22 are also fixed by fixing bolts.

[0025] The mandrel 3 is positioned on the connecting shaft 4, the mandrel 3 and the connecting shaft 4 are fixed by the connecting bolt 6, and the connecting shaft 6 is connected to the machine tool. ...

Abstract

The invention relates to a die which comprises an integral upper die (1) and an integral lower die (2), wherein a support device (7) is arranged between the integral upper die (1) and the integral lower die (2), the integral upper die (1) is formed by combination of a base upper die (11) and a rapid change upper die (12), the base upper die (11) is fixedly connected with a main oil cylinder of a machine tool, the rapid change upper die (12) is pressed downwards on the upper end surface of a workpiece, the rapid change upper die (12) adopts a dismountable replacement structure, and/or the integral lower die (2) is formed by combination of a base lower die (21) and a rapid change lower die (22), the base lower die (21) is fixedly connected with the machine tool, the lower end surface of the workpiece is located on the rapid change lower die, and the rapid change lower die adopts a dismountable replacement structure. According to the die provided by the invention, a support block is located above a support base or is separated, the lower die is well protected against bearing force when the die does not work, the support device is also prevented from being lost in work, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a mold. Background technique [0002] At present, in the field of press quenching of heat treatment parts, integral molds are used for the press quenching of main reducer and synchronizer parts. If the type is to be changed, all the integral molds need to be replaced. During the process of mold replacement, the parallelism between the molds and the The amount of pressing needs to be readjusted, the adjustment is very cumbersome, the cycle time is long, the labor force is also large, the efficiency of changing varieties is very low, and there is a hidden danger of unstable quality. [0003] like figure 1 As shown, the existing main reduction and synchronizer press quenching dies include an integral upper die 1, an integral lower die 2 and an axis 3, the workpiece 5 is located between the integral upper die 1 and the integral lower die 2, and the mandrel 3 is positioned on the connecting shaft 4, the two are fixed by the connec...
