Problems solved by technology
[0003] The cold extrusion molding flat dies currently in use are all integrally formed, and the impact resistance and extrusion resistance of the side plates are average, which limits the service life of the flat dies, and it is inconvenient to remove the blanks adhered to the inner side after long-term use It is used to cause blockage and affect product quality, and the entire flat mold cannot be used after a certain position of the flat mold is damaged or cracked, which also causes a certain degree of waste of resources and increases maintenance costs, so targeted improvements are required design

The invention discloses a flat mold for precision cold extrusion forming of copper bars, which comprises a flat mold body, the flat mold body is composed of a first side plate, a second side plate and a bottom plate spliced together, and the middle part of the bottom plate is provided with an extrusion Out of the groove, the second side plate and the first side plate are provided with several first installation holes transversely from top to bottom, and the inside of the first installation hole is provided with a Locked pull screws, the first side plate and the inside of the bottom plate are longitudinally provided with a second installation hole, and the second installation hole communicates with the first installation hole, and the second installation hole is provided with a connection between the bottom plate and the first installation hole. U-shaped bar for side panel locking. The flat mold has stronger impact resistance and compression resistance, and a longer service life. After a long period of use, the entire flat mold can be disassembled for repair, or the damaged side plate or bottom plate can be replaced, saving resources and reducing costs. maintenance costs.
Description
technical field [0001] The invention belongs to the technical field of copper bar processing dies, and in particular relates to a copper bar precision cold extrusion forming flat die. Background technique [0002] Cold extrusion is a processing method in which the metal blank is placed in the cold extrusion die cavity, and at room temperature, the punch fixed on the press is applied to the blank to cause plastic deformation of the metal blank to produce parts. my country has been able to cold-extrude metals such as lead, tin, aluminum, copper, zinc and their alloys, low-carbon steel, medium-carbon steel, tool steel, low-alloy steel, and stainless steel, and even to bearing steel, high-carbon high-aluminum alloys, etc. Tool steel, high-speed steel, etc. can also be cold-extruded with a certain amount of deformation. In terms of extrusion equipment, my country already has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general...
