Abstract
The utility model discloses a tool for processing a side protection jack flat cylinder bottom forging piece, which comprises an upper forging die and a lower forging die, wherein a cavity of the side protection jack flat cylinder bottom forging piece is arranged between the upper forging die and the lower forging die. And machining allowance and tolerance zones are reserved in the cavity, so that the requirement of subsequent machining is met. Blanking by using round steel, forging and forming by using a forging tool, and then carrying out subsequent processing. Not only saves raw materials, but also avoids the defects of the casting through forging processing, improves the structure and mechanical property of the casting, and ensures the continuity of the metal fiber structure. The one-step forming of the side-protecting jack flat cylinder bottom forge piece is achieved, the subsequent machining amount and machining difficulty are reduced, the production efficiency is improved, the quality is guaranteed, and meanwhile the cost is saved.
Description
Technical Field
The utility model relates to a tool for a hydraulic support for a coal mine, in particular to a tool for processing a side protection jack flat cylinder bottom forging.
Background
The hydraulic support has side protecting jack in the front end of the top beam, double acting hydraulic cylinder to make the side protecting plate swing up and down to adapt to the change of geological condition, and has both top contacting performance and side stripping preventing function. The side protection jack mainly comprises a cylinder body, a piston rod, a guide sleeve, a sealing piece and the like. The cylinder body comprises a cylinder bottom, a cylinder pipe and the like. The cylinder bottom is a connecting part of the jack and the protecting wall and is used for connecting the jack and the protecting wall and generating pressure to drive the piston rod to reciprocate.
The flat cylinder bottom of the side protection jack is generally made of 30CrMnSi, 27SiMn and 35 alloy steel, and the shape is complex.
In the prior art:
round steel is adopted for processing, the redundant part needs to be processed and removed, the subsequent processing amount is large, the economical efficiency is poor, and raw materials are wasted;
cast steel is adopted for casting, and various defects such as poor overall mechanical property, poor overall fatigue resistance and poor impact resistance exist. The cast product has air holes, looseness, inclusions, cracks, shrinkage porosity and the like, and is easy to damage when bearing large load and tensile stress.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a tool for processing a flat cylinder bottom forging of a side protection jack.
The purpose of the utility model is realized by the following technical scheme:
the tool for processing the side protection jack flat cylinder bottom forge piece comprises an upper forging die and a lower forging die, wherein a cavity of the side protection jack flat cylinder bottom forge piece is arranged between the upper forging die and the lower forging die.
According to the technical scheme provided by the utility model, the tool for processing the flat cylinder bottom forging of the side protection jack provided by the embodiment of the utility model is blanked by using round steel, and is forged and formed by using the tool, so that raw materials are saved, the defects of a casting can be avoided through forging, the tissue structure and the mechanical property of the casting are improved, and the continuity of the metal fiber tissue is ensured.

Detailed Description
The embodiments of the present invention will be described in further detail below. Details which are not described in detail in the embodiments of the utility model belong to the prior art which is known to the person skilled in the art.
The utility model discloses a tool for processing a flat cylinder bottom forging of a side protection jack, and a preferred embodiment of the tool is shown in figures 1 and 2:
the forging die comprises an upper forging die and a lower forging die, wherein a cavity of a side protection jack flat cylinder bottom forging piece is arranged between the upper forging die and the lower forging die.
And machining allowance and tolerance zones are reserved in the cavity, so that the requirement of subsequent machining is met.
Blanking by using round steel, forging and forming by using a forging tool, and then carrying out subsequent processing.
According to the tool for processing the flat cylinder bottom forging of the side protection jack, round steel is used for blanking, and the tool is forged and formed, so that raw materials are saved, the defects of a casting can be avoided through forging processing, the tissue structure and the mechanical property of the casting are improved, and the continuity of metal fiber tissue is guaranteed. The one-step forming of the flat cylinder bottom forge piece of the side protection jack is realized, the subsequent processing amount and the processing difficulty are reduced, the production efficiency is improved, the quality is ensured, and meanwhile, the cost is saved.
The utility model develops research aiming at the flat cylinder bottom of the hydraulic support side-protecting jack, ensures the machining allowance and reasonably sets tolerance by designing a forging tool, and forges by using a tool die to ensure that the appearance of the flat cylinder bottom is forged and formed at one time, reduces subsequent machining amount and saves raw materials, and the specific technical key points are as follows:
the process is novel, the novel forging tool structure is adopted, and the product size is formed in one step.
The machining allowance is guaranteed, the tolerance zone is reasonably arranged, and the subsequent machining requirements are met.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
