Technical Field
The invention relates to the field of extrusion die processing, in particular to an improved process for a fabrication hole of an extrusion die.
Background
When manufacturing an extrusion die, wire cutting is often required to be performed on an upper die and a lower die of the extrusion die to obtain a desired structure, and before performing the wire cutting, a wire cutting threading hole needs to be firstly arranged on the die. In the prior art, an upper die and a lower die are processed together as a whole to ensure the concentricity of a product, and the sizes of the rabbets of each set of general extrusion dies are different and cannot be used universally, so that each set of die needs to be provided with holes independently.
Disclosure of Invention
The present invention aims to provide an improved process for forming a fabrication hole of an extrusion die, which addresses the above-mentioned drawbacks of the prior art.
In order to achieve the purpose of the invention, the invention adopts the following technical scheme:
an improved technology of a fabrication hole of an extrusion die is characterized by comprising the following steps:
a. formulating a specification table;
b. programming the die according to a drawing;
c. the upper die and the lower die are processed in a split manner;
d. selecting a fabrication hole processing program to process the fabrication hole;
e. and wire cutting is carried out on the slow-moving wire.
In addition, the invention also comprises the following auxiliary technical scheme:
and c, milling the split machining of the upper die and the lower die in the step c through a CNC machining center.
And c, processing procedures of the process holes of the dies with the same specification can be universal.
And e, controlling the concentricity of the wire-electrode cutting slow-moving wire in the step e by adopting an automatic centering method, and finding out the center of the die through a three-point circle.
When the process hole is machined, a tungsten steel cutter with the diameter of 4mm is used, and machining is carried out at the spindle speed of 5000r/min, the feeding rate of 1000-1200 mm/min and the feeding amount of 0.15 mm/r.
Compared with the prior art, the invention has the advantages that: the concentricity of the product can be effectively controlled within 0.01mm in the automatic division of the slow wire moving through the wire cutting, and compared with the integral processing, the split processing of the upper die and the lower die only needs to configure a standard wire cutting wire penetrating hole according to the specification of the product, thereby reducing the waiting time and correspondingly shortening the processing time.
Drawings
FIG. 1 is a process flow diagram of the present invention.
Detailed Description
The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.
The upper die and the lower die are processed in a split mode, namely the upper die and the lower die are not processed integrally in the processing process of the upper die and the lower die, the upper die and the lower die are milled respectively, the upper die and the lower die are subjected to line cutting respectively, and after the processing is finished, the upper die and the lower die are spliced for production. Because the concentricity of the product is easy to be out of tolerance due to the split processing of the upper die and the lower die, the concentricity of the upper die and the lower die needs to be controlled by adopting an automatic centering method before online cutting.
As shown in fig. 1, the split machining of the upper and lower dies includes the following steps: a. formulating a specification table; b. programming the die according to a drawing; c. the upper die and the lower die are processed in a split manner; d. selecting a fabrication hole processing program to process the fabrication hole; e. and wire cutting is carried out on the slow-moving wire. In the step a, the previous product drawings are classified according to specifications, and the procedures of the fabrication holes (namely wire-electrode cutting threading holes) of the products with the same specifications are the same without rewriting the procedures. Programming the cavities of the upper die and the lower die by a programmer, milling the structures of the upper die and the lower die through a CNC machining center, and drilling the upper die and the lower die respectively to obtain the fabrication holes of the upper die and the lower die. When the process hole is machined, a tungsten steel cutter with the diameter of 4mm is used, and machining is carried out at the spindle speed of 5000r/min, the feeding rate of 1000-1200 mm/min and the feeding amount of 0.15 mm/r.
After the fabrication holes of the upper die and the lower die are machined, linear cutting is carried out, the position of the linear cutting slow-moving wire is determined by an automatic centering method, and the concentricity of the die cavities in the upper die and the lower die after the linear cutting is ensured. After the upper die and the lower die are processed, the upper die and the lower die are spliced for production.
And e, the wire-electrode cutting slow wire walking in the step e adopts an automatic centering method, the molybdenum wire is controlled to touch three points on the periphery of the die, and the center of the circle is found out through a three-point circle, namely the center of the die. The method can effectively control the concentricity of the product to be within 0.01 mm.
According to the invention, the concentricity of the product can be effectively controlled within 0.01mm in the automatic division of the slow-moving wire by wire cutting, and compared with the integral processing, the split processing of the upper die and the lower die only needs to configure the standard wire cutting wire penetrating hole according to the specification of the product, so that the waiting time is reduced, and the processing time is correspondingly shortened.
It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
