Abstract
The invention relates to the technical field of cold stamping dies, in particular to a cold stamping die structure with a clamping plate. According to the die, the reinforcing clamping plate is additionally arranged, so that the strength of the hanging groove of the die pressing plate can be guaranteed, the die is ensured to be safely used, the die does not need to be reworked, and the cost for restarting the die is saved; normal production is guaranteed, and the risk of production halt of a company is avoided. The reinforced clamping plate is modified, is widely applicable and can be widely applied to parts such as local reinforcing dies or other equipment.
Description
Technical Field
The invention relates to the technical field of cold stamping dies, in particular to a cold stamping die structure with a clamping plate.
Background
In the cold stamping process, a plurality of die pressure plate side pin hanging groove parts are damaged on site, so that the die pressure plate side pin hanging groove parts cannot be used. The die platens are all castings which can lead to long periods of downtime for the company if the remanufacturing cycle is long. Therefore, there is a need to solve such problems, ensure safe use of the mold, avoid damage to the mold platen and reduce the cost of reopening the mold platen.
Disclosure of Invention
In order to solve the problems, the invention provides a cold stamping die structure with a clamping plate, and the reinforcing clamping plate is arranged, so that a die pressing plate is not damaged, and the production efficiency is ensured. The specific technical scheme is as follows:
a cold stamping die structure with a clamping plate comprises an upper die, a pressure plate return nitrogen spring, a working side pin, a pressure plate and a reinforcing clamping plate;
the pressing plate comprises a transverse plate and two side plates arranged on the same side of the transverse plate, a pressing plate return nitrogen spring is respectively arranged on the two side plates, and the pressing plate is fixedly connected with the upper die through the pressing plate return nitrogen spring;
a groove is formed in the other side of the two side plates in the middle of the transverse plate, a through hole is formed in one side, far away from the upper die, in the groove, the size of the through hole is matched with that of the working side pin, and the working side pin can be inserted into the through hole;
the reinforced clamping plate is arranged on one side of the groove of the transverse plate, a clamping groove is formed in one side of the reinforced clamping plate, so that the reinforced clamping plate is clamped on the transverse plate, the middle of the reinforced clamping plate is hollowed out, the groove corresponds to the hollowed-out portion, and the working side pin can move up and down in the hollowed-out portion.
Furthermore, a plurality of threaded holes are formed in the reinforcing clamping plate and used for fixing the reinforcing clamping plate on the transverse plate.
Further, the number of the screw holes is 4 ~ 8.
According to the die, the reinforcing clamping plate is additionally arranged, so that the strength of the hanging groove of the die pressing plate can be guaranteed, the die is ensured to be safely used, the die does not need to be reworked, and the cost for restarting the die is saved; normal production is guaranteed, and the risk of production halt of a company is avoided. The reinforced clamping plate is modified, is widely applicable and can be widely applied to parts such as local reinforcing dies or other equipment.

Detailed Description
The invention will be further described with reference to the accompanying figures 1 to 3 of the specification:
a cold stamping die structure with a clamping plate comprises: the device comprises an upper die 1, a pressure plate return nitrogen spring 2, a working side pin 3, a pressure plate 4 and a reinforcing clamping plate 5;
the pressure plate 4 comprises a transverse plate 41 and two side plates 42 arranged on the same side of the transverse plate 41, the two side plates 42 are respectively provided with a pressure plate return nitrogen spring 2, and the pressure plate 4 is fixedly connected with the upper die 1 through the pressure plate return nitrogen spring 2; a groove 43 is arranged on the other side of the two side plates 42 in the middle of the transverse plate 41, a through hole 44 is arranged on one side of the groove 43 far away from the upper die 1, the size of the through hole 44 is matched with that of the working side pin 3, and the working side pin 3 can be inserted into the through hole 44.
The reinforcing clamping plate 5 is arranged on one side of the groove 43 of the transverse plate 41, the clamping groove 51 is formed in one side of the reinforcing clamping plate 5, so that the reinforcing clamping plate 5 is clamped on the transverse plate 41, the middle of the reinforcing clamping plate 5 is hollowed out, the groove 43 corresponds to a hollowed-out portion, and the working side pin 3 can move up and down in the hollowed-out portion.
The reinforcing clamping plate 5 is provided with a plurality of threaded holes for fixing the reinforcing clamping plate 5 on the transverse plate 41.
The number of the threaded holes is 4 ~ 8.
The mould 1 descends on the during operation, and the pressure flitch 4 descends together, and the contact atress of work side round pin 3 and reinforcing cardboard 5 this moment prevents to press flitch 4 to fall. When the pressure plate 4 is contacted with the lower die, the pressure plate return nitrogen spring 2 is compressed, the working side pin 3 is separated from the reinforcing clamping plate 5 at the moment and is not stressed, the upper die 1 starts to move upwards after the lower dead point, the pressure plate 4 is not moved at the moment, the return nitrogen spring 2 is slowly released, the pressure plate return nitrogen spring 2 is in a free state when the pressure plate 4 is separated from the lower die, the working side pin 3 is contacted with the reinforcing clamping plate 5 again and is stressed at the moment until the upper dead point of the equipment, and one punching cycle is completed.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
