Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
In the practice of removing wax seal from valve sleeve parts as shown in fig. 1, various materials and methods have been tried, which are not only inefficient, but also have poor and unstable wax seal removing effect, and thus have become bottlenecks at that time. The surface treatment voltage of the surface of the D surface of the valve sleeve part is high, the current is large, so the protection requirement on the part is strict, and otherwise, the qualification rate of the part is very low. For example, in the selection of the material of the tool, plastic, wood, bamboo chips, copper, aluminum, etc. are all tried to be soft materials. These materials are not only relatively soft, but also have poor sharpness and wear resistance, and their main reason for their selection is that wax seal removal is a purely manual operation, and if sharp and wear resistant materials are used, parts can be easily damaged, which can result in rejection. For another example, in production, different workers are arranged to operate, the tool is machined into different shapes, the process is arranged to be adjusted for multiple times, and the overall effect is difficult to meet the requirements of progress and quality.
Before the utility model, because the wax removing and sealing tool and the method are not suitable, the defects caused to the work are mainly as follows:
the operation difficulty is large. The method mainly comprises the steps that a tool machining method and effect are difficult to meet the use requirement, the contact angle of a tool and a part is difficult to control, the overall contact of the tool and the part is difficult to control, a proper working state is difficult to maintain and the like;
the tool is difficult to meet the requirements of mass production. Because the performance of the material determines that the wear resistance is poor, the frequency of re-grinding and replacing the tool is high, in addition, the removal effect is poor, and the repeated reworking is needed, so that the requirement of mass production is difficult to meet from the perspective of the tool.
The wax seal removal quality is difficult to meet. The reasons for the above two aspects are instability factors, which determine the unstable quality of wax seal removal. In practical production, the mass production of the product is difficult to meet the requirements of customers and cost until the cutter of the utility model is normally used.
In general, the dewaxing sealing cutter of the utility model solves the above problems more comprehensively.
First embodiment of the utility model
As shown in figure 2, the tool for removing wax sealing of the circular inner hole of the metal part comprises a plug piece 2, an elastic blade 3 and a tool rest 4, wherein the tool rest 4 is cylindrical, one end of the tool rest is a handle, the other end of the tool rest is provided with symmetrical chordwise grooves for mounting the blade 3, and the blade 3 is mounted in the chordwise grooves.
One end of the blade 3 is chamfered to guide the blade 3 into the inner bore of the valve housing 1.
The tool for removing the wax seal of the circular inner hole of the metal part has the following specific operation:
the handle, namely the tool rest 4, is held, the tool of the utility model is inserted into the inner hole of the valve sleeve 1 until the total length of the valve sleeve 1 is within the range of the blade part of the blade 3, and the handle is rotated at a slow speed against the rotation direction of the blade while being inserted, so that the blade 3 is prevented from scratching the surface of the inner hole of the valve sleeve 1; rotating the cutter along the 3-direction of the blade for more than 360 degrees, and removing wax seal; the cutter is drawn out to bring out the removed wax, and the handle is rotated slowly against the rotation direction of the blade 3 while drawing out, so that the blade 3 is prevented from scratching the surface of the inner hole of the valve sleeve 1. If the wax seal can not be removed by rotating 360 degrees once, the tool can be continuously rotated, or the tool is withdrawn to remove the wax seal again after the wax on the blade 3 is cleaned.
From the above description, it can be seen that the tool of the present invention shown in fig. 2 is simple to use and operate, and besides the requirement of preventing reverse rotation of the surface of the scratched part during the entering and exiting processes, the whole wax seal removing process has no other operation requirement details, and all the requirements related to wax seal removing are automatically adjusted by the tool of the present invention. The present invention cutter has a special design to support the process of removing the wax seal. These features mainly include:
the cutter is provided with a plurality of blades 3, and the circle centers of the blades are symmetrically distributed, so that the cutter can be automatically centered and positioned;
the blade 3 of the cutter is made of elastic materials, so that the elasticity is good, and the cutting edge of the blade 3 can be tightly attached to the surface of a part in real time;
the blade 3 of the cutter is made of spring steel, has higher hardness than the material of the valve sleeve 1 and wax, and has good wear resistance and long service life;
the cutting angle can be automatically ensured to be unchanged in the working process of the cutter, and the wax seal removing process is stable;
the front angle of the cutter is proper, and the phenomenon of cutter gnawing cannot occur in the wax seal removing process, so that the surface damage of parts cannot be caused;
the cutter of the utility model has the back angle shown in figure 4, and ensures good wax seal removing effect.
In the case where the two chordal grooves of the inventive tool shown in fig. 12 may be through-cut, the insert 3 may be integrally formed, enabling easier installation of the insert 3.
The tool of the present invention shown in fig. 5 is fitted with a special sharpening sleeve 5 made of cast iron for sharpening the cutting edge of the blade 3. When the blade 3 is ground, the grinding paste is coated in the grinding sleeve 5 and is arranged outside the cutter, and the blade 3 is ground through the relative rotation of the cutter and the grinding sleeve 5. The handle of the inventive tool is usually clamped to the grinding head and the sharpening sleeve 5 is held by hand to sharpen the blade 3, or vice versa.
As shown in fig. 6, which is a partially enlarged view of the sharpening process of the blade 3, the blade 3 and the sharpening sleeve 5 are fully in contact with each other without a clearance angle. The diameter of the coping sleeve 5 is smaller than the phi D of the valve sleeve 1, so that a back angle is naturally formed when the coping blade 3 is matched with an inner hole of the valve sleeve 1, and the working process of removing wax seal is improved.
Second embodiment of the utility model
As shown in fig. 7, the present invention is applied to machining the sealing edge portion of the metal shaft seal 8 by using the tool of the present invention, and the metal shaft seal 8 is used in cooperation with the clamp ring 6, the sleeve 7, and the shaft 9.
As shown in fig. 8, a detailed enlarged view of a sealing edge portion C of the metal shaft seal 8 to which the tool of the present invention is applied is shown.
The blade cutter of the utility model is applied to the processing of the metal shaft seal 8 shown in fig. 7, and can form the part back angle shown in fig. 8, thus improving the sealing effect.
Because the metal shaft seal 8 is in interference fit with the shaft sleeve 7, the metal shaft seal 8 has compression deformation, and the change of temperature in the working process can also cause the change of the shape of the metal shaft seal 8, and the factors can cause the change of the contact state of the sealing surface of the metal shaft seal 8. Since the conventional metal shaft seal 8 is of the clearance-free type, this condition can exist only under certain conditions. The shape change of the metal shaft seal 8 in the whole process necessarily causes the contact state of the sealing surface of the metal shaft seal 8 to change in the working process, i.e. the sealing effect also changes, and some states may be beyond the design expectation. If the blade coping method of the utility model is applied to process the metal shaft seal 8 to form a proper back angle of the metal shaft seal 8, the change of the shape of the metal shaft seal 8 can cause the change of the back angle, but the back angle is kept in a certain range, which can ensure that the contact state of the sealing surface of the metal shaft seal 8 in the whole working process accords with the design expectation, and the sealing effect also accords with the design expectation.
Third embodiment of the utility model
As shown in fig. 9, an example of application of the tool of the present invention to machining the seal edge portion of a metal seal ring 10 is shown.
As shown in fig. 10, a partial enlarged view of a seal blade portion a of the metal seal ring 10 is shown.
As shown in fig. 11, a partial enlarged view B of the seal edge portion of the metal seal ring 10 to which the tool of the present invention is applied is shown.
The blade thinning method of the blade of the present invention is applied to the machining of the metal seal ring 10 as shown in fig. 9, and can form the part relief angle as shown in fig. 11, so that the sealing effect without the relief angle as shown in fig. 10 can be improved.
The metal seal ring 10 shown in fig. 9 is mounted in a state of compression deformation, and changes in temperature during operation also cause changes in the shape of the metal seal ring 10, and these factors cause changes in the contact state of the seal surfaces thereof. Because conventional metal seal rings 10 are of the form without a back angle, this condition can only exist under certain conditions. The shape change of the metal seal ring 10 in the whole process necessarily causes the contact state of the sealing surface of the metal seal ring 10 to change in the working process, that is, the sealing effect also changes, and some states may be beyond the design expectation. If the metal seal ring 10 is machined by the blade thinning method of the present invention to form the proper back angle of the metal seal ring 10, the shape change of the metal seal ring 10 will cause the change of the back angle, but the back angle is kept within a certain range, which will ensure that the contact state of the sealing surface of the metal seal ring 10 in the whole working process meets the design expectation, and the sealing effect also meets the design expectation.
