Description
Technical Field
The utility model relates to a deep hole processing technology field, especially a reprocess radial micropore's processing structure bottom the mould deep hole.
Background
The existing die-casting die is large in size, and small holes are machined at the bottoms of deep holes. The drill bit can be used for processing drill bits without the diameter of more than 150 times, or the deep hole processing normally comprises the steps of firstly processing small holes, and then processing large holes, or the deep hole processing has no technology which can process small holes with the diameter of more than 150 times, or a die with the material hardness of 48-52 HRC.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is: the processing structure for processing the radial micropores at the bottom of the deep hole of the die solves the problem of processing the small holes at the bottom of the deep hole of a large die-casting die.
The technical scheme of the utility model is that: a deep hole is prefabricated on a die, and a hole with a small diameter is machined at the bottom of the deep hole. The structure comprises a red copper electrode and a nylon sleeve. The central processing of the nylon sleeve is matched with the same diameter and the same aperture of the red copper electrode, and the outer diameter of the nylon sleeve is reserved with a movable gap according to the requirements of the diameter and the position degree of a hole to be processed.
The rotary surface of the nylon sleeve is provided with a spiral groove, the spiral angle of the spiral groove is 75 degrees, and the thread pitch is 5 mm. The spiral groove can be used as a groove for oil discharge, gas discharge and slag discharge.
The utility model has the advantages that: the utility model discloses whole length is mainly constituteed by red copper electrode and nylon cover, adopts between the two to dismantle the increase or change, through changing different length red copper electrode and nylon cover, can change the utility model discloses a whole length, the size in processing hole. The utility model has wider application range.
Drawings
The invention will be further described with reference to the following drawings and examples:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of a nylon sleeve;
wherein: 1. a nylon sleeve; 2. a red copper electrode; 3. micropores; 4. deep holes; 5. and (5) molding.
Detailed Description
The utility model discloses a preferred embodiment 1:
a deep hole 4 is prefabricated on a mould 5, and a small-diameter micropore 3 is machined at the bottom of the deep hole 4. The structure comprises a red copper electrode 2 and a nylon sleeve 1. The central processing of the nylon sleeve 1 is matched with the red copper electrode 2 with the same diameter and the same aperture, and the outer diameter of the nylon sleeve 1 is reserved with a movable gap according to the requirements of the diameter and the position degree of a hole to be processed.
The rotary surface of the nylon sleeve 1 is provided with a spiral groove, the spiral angle of the spiral groove is 75 degrees, and the thread pitch is 5 mm. The spiral groove can be used as a groove for oil discharge, gas discharge and slag discharge.
The utility model discloses a preferred embodiment 2:
as shown in fig. 1, a micropore 3 is machined at the bottom of a deep hole 4 on a mold 5, then a nylon sleeve 1 is tightly sleeved on a red copper electrode 2, an inner hole and an outer hole are machined according to the diameter of the red copper electrode 2, the length of the nylon sleeve 1 is 8.0mm according to experience, and a movable gap is arranged according to the tolerance of the hole to be machined between the nylon sleeve 1 and the deep hole 4.
The nylon sleeve 1 is required to be processed with a spiral groove for oil and slag discharge, and if the straight groove nylon sleeve is easy to break, the nylon sleeve is in a spiral mode. The helix angle of the helical groove is 75 DEG, and the pitch is 5 mm. The spiral groove can be used as a groove for oil discharge, gas discharge and slag discharge.
The whole length of this structure is mainly by red copper electrode 2 and nylon cover 1 constitution, adopts between the two to dismantle the connection, through the red copper electrode 2 or the nylon cover 1 of different diameters of changing different length, can change the whole length and the diameter of this structure. And the number of the nylon sleeves 1 is increased according to the adjustment of the depth of the hole, so that the structure has a wider application range.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical concepts of the present invention be covered by the claims of the present invention.
