Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the following description will make the technical solutions of the embodiments of the present invention clear and complete. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

An embodiment of the present application provides a method for processing an insert, referring to fig. 1, where the method for processing an insert is used for preparing an insert as described above, and includes the following steps:

s10, obtaining a plate to be processed;

in this embodiment, the insert is an irregular mold fitting for being inserted into a mold, and functions to fix a space between a mold plate and a filling mold plate. The insert is usually machined by wire cutting, as shown in fig. 2, after the outer shape is machined by wire cutting, the insert 1 and the plate 2 to be machined are connected by a rib structure 3, at this time, the rib structure 3 needs to be cut off at a position, which is adjacent to the insert, outside the insert, for example, a position, which is shown as a broken line 4, in the drawing, the insert 1 is separated from the plate 2 to be machined, the preset edge of the workpiece should be originally at a position, which is shown as a broken line 5, of the preset edge of the insert, after the cutting, the actual edge of the workpiece extends to the position, which is shown as a broken line 4, of the cutting position, so that an outwardly protruding rib position is left on the workpiece, and the outwardly protruding rib position may not be smoothly embedded into and/or taken out from the die, so at present, after the wire cutting, the outwardly protruding rib position needs to be further removed by a surface grinder. Under the condition that the number of the inserts needed by the die is large, for example, a stamping die, each insert is required to be independently removed with the convex rib position through a grinding machine, the cost is high, the manpower requirement is large, and the automation degree is low.

As an example, a plate to be processed may be selected according to a size specification, a material, etc. of the insert to be processed, where the thickness of the plate to be processed may be the same as or different from the height of the insert to be processed, and in the case that the thickness of the plate to be processed is different from the height of the insert to be processed, after the wire-cut processing, the height of the insert is further required to be ground to a desired target height; under the condition that the thickness of the plate to be processed is the same as the height of the insert to be processed, grinding of the height of the insert is not needed after linear cutting processing, time cost and labor cost for grinding the height of the insert can be further saved, and the original processing process of the insert is sequentially linear cutting processing, grinding machine grinding and other processing procedures, wherein grinding machine grinding is used for removing protruding rib positions and grinding of the height of the insert, and under the condition that grinding of the height of the insert is not needed, the step of grinding machine grinding can be completely omitted in the processing process of the insert, so that labor cost and time cost can be saved, the process flow can be simplified, equipment investment can be reduced, and the processing cost of the insert can be effectively reduced.

As an example, a piece of sheet material to be processed may be used for processing one or more inserts, and in the case that a piece of sheet material to be processed is used for processing a plurality of inserts, typesetting may be performed in advance, and inserts with the same height specification may be typeset onto the same sheet material to be processed for processing. In this way, compared with the mode that each insert is respectively subjected to high grinding after being cut online, the high grinding of a plurality of inserts with the same height specification can be realized through one grinding, and the labor cost and the time cost are reduced exponentially.

Optionally, the step of obtaining the sheet material to be processed includes:

As an example, the thickness of the sheet to be processed may be determined according to a preset insert height, so that the sheet to be processed with a corresponding thickness is directly purchased, so that the thickness of the sheet to be processed is the same as the height of the insert to be processed.

Optionally, the step of obtaining the sheet material to be processed includes:

s11, obtaining an initial plate material;

and step S12, processing the thickness of the initial plate to a preset insert height to obtain the plate to be processed.

As an example, in the case that the thickness of the available initial sheet material is inconsistent with the preset insert height, after the initial sheet material is obtained, the thickness of the initial sheet material may be processed to the preset insert height by grinding, cutting, and the like, so as to obtain the sheet material to be processed. The processing step of the height of the inserts is advanced to the front of wire cutting, so that the height processing of the inserts with the same height specification can be finished in batches, and the labor cost and the time cost can be reduced by times.

As an example, in the case that the thickness of the initial sheet material that can be obtained is inconsistent with the preset insert height, after the initial sheet material is obtained, the thickness of the initial sheet material may be ground to the preset insert height by a large water mill machine tool, so as to obtain the sheet material to be processed.

And S20, performing linear cutting treatment on the plate to be processed to obtain the insert with the rib grooves.

In this embodiment, wire cutting refers to a machining method in which a moving wire (molybdenum wire, copper wire, or alloy wire) is used as a wire electrode, and a pulse spark discharge is applied between the wire electrode and a workpiece to generate high temperature to melt or vaporize metal and form a slit, thereby cutting out a part. For convenience of explanation, the embodiment will be described later with the case that the wire-cut conductive path is parallel to the thickness direction of the sheet to be processed, but in the actual processing, the cutting direction may be adjusted according to the structure, shape, specification, etc. of the insert actually required to be processed, which is not limited in this embodiment.

step S22, writing a linear cutting program according to the cutting pattern;

and S23, performing linear cutting treatment on the plate to be processed according to the cutting path by linear cutting equipment based on the linear cutting program to obtain the insert with the rib grooves.

After linear cutting is completed on other side surface areas of the insert except the side surface area connected with the rib structure, the rib structure is cut off in the preset outer surface of the insert, so that the original convex rib position is recessed towards the inside of the insert, and the insert with the rib position groove is obtained. The wire cutting equipment can be a slow wire-moving machine tool, a medium wire-moving machine tool and the like.

Optionally, the wire cutting device is a slow wire-moving machine tool.

and step A20, cutting the inner side of the initial product from the connection area of the rib structure and the initial product so as to separate the initial product from the plate to be processed, and forming a rib groove on the cutting surface of the initial product to obtain the insert with the rib groove.

In this embodiment, the rib position grooves may be formed simultaneously when the rib structure is cut through the wire cutting process.

As an example, the step of synchronously forming the rib position grooves when cutting the rib structure includes: placing the plate to be processed on a workbench, starting a wire cutting device, moving a metal wire on the wire cutting device based on a preset cutting path, cutting the plate to be processed, repairing the shape of the side surface of a parent-child first in the process of cutting the plate to be processed, and obtaining an initial product connected with the plate to be processed through a rib structure after wire cutting is completed in other side surface areas except for the side surface area connected with the rib structure; and then, controlling the metal wire on the wire cutting equipment, cutting the inner side of the initial product from the connection area of the rib structure and the initial product so as to separate the initial product from the plate to be processed, and forming a rib position groove on the cutting surface of the initial product, so that the rib position which is originally protruded outwards is recessed inwards to obtain the insert with the rib position groove. Wherein the connection area refers to an area of a certain range of the surface of the initial product from the position where the rib structure is connected with the initial product.
