Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the following further detailed description of the embodiments of the present application with reference to the drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
As shown in fig. 3 and 4, the present invention discloses a combined storage structure for a stamping die, which includes a plurality of combined supporting members disposed between an upper die 1 and a lower die 2. A combined supporting member is composed of a rigid storage block 3 and a nitrogen spring 4, wherein the lower end of the rigid storage block 3 is fixed on the lower die 2 through a hinge 5, and the nitrogen spring 4 is fixed on the upper die 1 or the lower die 2. The compression stroke d1 of the nitrogen spring 4 is greater than the length d2 of the rigid storage block 3, and the difference between the lengths is d1-d2, and Δ d can be set to 10 mm. The sum of the initial bearing forces of all the nitrogen springs 4 is configured to be greater than the gravity of the upper die 1, and specifically may be configured to be 1.5 times of the gravity of the upper die 1 itself.
The sum of the initial bearing forces of all the nitrogen springs 4 is configured to be larger than the gravity of the upper die 1: all the nitrogen springs 4 can support the upper die 1 alone when a single stamping die is stored in a normal state, and the rigid storage block 3 is not stressed.
It can be seen that, because the initial elastic pressure of the nitrogen spring 4 on the upper die 1 is greater than the gravity of the upper die 1, in the die changing process, the nitrogen spring 4 completely supports the upper die 1, and the rigid storage block 3 is not stressed, so that the rigid storage block 3 can be freely turned up and down. The rigid storage block 3 can be turned up and down under a production line without a press machine, so that the occupied time of the press machine is reduced, and the production efficiency is improved.
As shown in fig. 3, the mould is in the storage position with the rigid storage block 3 turned up. When the single mould is stored, the nitrogen spring 4 can fully support the upper mould 1, and the rigid storage block 3 is not stressed. In order to save the storage space of the die, a stacking storage mode of stamping dies is generally adopted, namely the die is continuously stacked above the upper die 1, at the moment, the nitrogen spring 4 is compressed to the length equal to that of the rigid storage block 3, and the rigid storage block 3 and the nitrogen spring 4 support the weight above the upper die 1 and the upper die 1 together.
As shown in fig. 5, when the die is in a production state, the rigid storage block 3 is turned down, and the upper die 1 is driven by the press machine to reciprocate up and down, so that the punch forming of the workpiece is completed. The nitrogen spring 4 is compressed as the upper die 1 descends, and functions to buffer and reduce noise.
Further, as shown in fig. 7, the shape of the stamping die is a rectangular structure, and the number of the combined supporting members can be four, and the combined supporting members are respectively arranged at the mounting areas 8 at the four corners of the stamping die, so that the stamping die is ensured to be stressed in a balanced manner during production and storage.
Further, as shown in fig. 3 and 4, the hinge 5 includes a fixing block 5a fixed to the outer side wall of the lower mold 2 and a connecting block 5b fixed to the outer side wall of the rigid storage block 3, and the connecting block 5b and the fixing block 5a are rotatably connected by a rotating pin 5 c. The rigid storage block 3 can be conveniently turned up and down through the hinge 5.
As shown in fig. 3 and 5, the rigid storage block 3 further includes: a first state of die storage, in which said rigid storage block 3 is located between the lower die 2 and the upper die 1; and in the second state of the mold production, the rigid storage block 3 is closely received on the outer side wall of the lower mold 2, and the normal production is not influenced.
Further, there is considered a problem that an operator forgets to turn down the rigid storage block 3 due to an operation mistake during preparation for production, which may cause a production accident. As shown in fig. 5 and 6, the combined storage structure for a press die according to the present invention further includes a sensor 6 fixed to the outer side wall of the lower die 2 for detecting whether the rigid storage block 3 is closely received on the outer side wall of the lower die 2. The sensor 6 is used to monitor whether the rigid storage block 3 is closely received against the outer side wall of the lower mold and to generate an electrical signal. The PLC of the press machine is connected with the sensor 6 and used for judging whether the rigid storage block 3 leans against the outer side wall of the lower die 2 or not according to the electric signals, if so, the press machine is controlled to start production, and if not, the press machine is controlled to stop. Thereby preventing the situation that the rigid storage block is forgotten to be turned down during production due to human manipulation errors.
More preferably, the rigid storage block 3 which is retracted is jumped in consideration of the large jitter of the press during the punching process, thereby causing the sensor 6 to sense the signal loss. The combined storage structure for the stamping die further comprises a magnetic cushion block 7 which is fixed on the outer side wall of the lower die 2 and used for adsorbing the rigid storage block 3. Because the rigid storage block 3 is usually made of steel, the rigid storage block is firmly adsorbed on the magnetic cushion block 7 in the production process of the die, and the stability of the sensing signal of the sensor 6 is ensured.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations as well.
