Abstract
The utility model provides a wax mould rounding tool, which comprises: the cutter, semicircular sleeve and handle. The cutter is provided with an arc-shaped cutter head. The semicircular sleeve is provided with a discharge port, and the arc-shaped cutter head extends into the inner arc surface side of the semicircular sleeve through the discharge port. The handle is fixed on the outer arc surface of the semicircular sleeve, and the cutter is fixed on the handle. By utilizing the semicircular sleeve and the cutter, the fillet with the same shape can be trimmed along the edge of the wax mould, and the casting quality is improved.
Description
Technical Field
The utility model relates to a wax mould rounding tool.
Background
The surface fillet direct influence investment casting die shell intensity of wax matrix, but because workman group fitment wax in-process cutting concatenation etc. requirement, the wax base can have various closed angles, needs the workman to repair the closed angle into the stress that the fillet reduced here when pouring to improve foundry goods pouring quality. The common fillet cutting tool is difficult to keep stable due to the force and direction in the cutting process of an operator, so that the depth and the direction of the cut fillet are different, and the casting quality of a formwork is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defect of poor fillet cutting quality of a wax mould in the prior art, and provides a wax mould fillet trimming tool capable of solving the problem.
The utility model solves the technical problems through the following technical scheme:
the utility model provides a wax matrix radius angle instrument which characterized in that, it is including:
a cutter having a circular arc-shaped cutting head;
the cutter comprises a semicircular sleeve, a cutter head and a cutter head, wherein a discharge port is formed in the semicircular sleeve, and the arc-shaped cutter head extends into the inner arc surface side of the semicircular sleeve through the discharge port;
the handle is fixed on the outer arc surface of the semicircular sleeve, and the cutter is fixed on the handle.
Preferably, the lower side of the discharge opening is directed obliquely upwards, and the knife extends in the direction of extension of the lower side of the discharge opening.
Preferably, the cutting edge of the knife is oriented vertically upwards.
Preferably, the handle includes a holding portion and a fixing portion, the fixing portion is fixed to the semicircular sleeve, the cutter is fixed to the fixing portion, and an extending direction of the fixing portion is identical to an extending direction of the lower side of the discharge opening.
Preferably, the fixing portion has a threaded hole, the tail portion of the cutter has the notch, and the screw presses the notch and is connected to the threaded hole.
On the basis of the common knowledge in the field, the above preferred conditions can be combined randomly to obtain the preferred embodiments of the utility model.
The positive progress effects of the utility model are as follows: by utilizing the semicircular sleeve and the cutter, the fillet with the same shape can be trimmed along the edge of the wax mould, and the casting quality is improved.

Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
Fig. 1 and 2 show a wax pattern rounding tool comprising: a cutter 100, a semi-circular sleeve 200 and a handle 300. The cutter 100 has a circular arc type cutting head 110. The semicircular sleeve 200 is provided with a discharge opening 210, and the arc-shaped tool bit 110 extends into the inner arc surface side of the semicircular sleeve 200 through the discharge opening 210. The handle 300 is fixed to the outer arc surface of the semicircular sleeve 200, and the cutter 100 is fixed to the handle 300.
When the tool is used for rounding the wax mould, the semicircular sleeve 200 is vertically placed and attached to the vertical edge of the wax mould to be rounded, an operator holds the handle 300, the inner arc surface of the semicircular sleeve 200 is kept to be attached to the wax mould, the inner arc surface is upwards pushed along the vertical direction, the arc-shaped cutter head 110 cuts off the sharp corner of the wax mould, and the cut waste is discharged from the discharge hole 210 along the cutter face. The semicircular sleeve 200 plays a good role in guiding and positioning, so that the cutting angle and depth of the cutter 100 are kept unchanged, and the quality of subsequent casting is improved.
In order to be able to better discharge the waste material, the lower side of the discharge opening 210 is inclined upwards, the knife 100 extending in the direction of extension of the lower side of the discharge opening 210.
In this embodiment, the blade of the tool 100 is oriented vertically upward. The blade is upward to facilitate cutting off sharp corners upward.
In this embodiment, the handle 300 includes a holding portion 310 and a fixing portion 320, the fixing portion 320 is fixed to the semicircular sleeve 200, the cutter 100 is fixed to the fixing portion 320, and the extending direction of the fixing portion 320 is the same as the extending direction of the lower side of the discharge opening 210. The holding portion 310 and the fixing portion 320 form a certain angle, which is more convenient for the operator to exert force upwards.
In order to improve the versatility of the tool, in this embodiment, the fixing portion 320 has a threaded hole (not shown), the rear portion of the cutter 100 has a notch 120, and the screw 400 is pressed into the notch 120 and connected to the threaded hole. For wax patterns with different sizes and different fillet requirements, different cutters 100 can be replaced, so that different fillets can be cut.
While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the utility model is defined by the appended claims. Various changes or modifications to these embodiments may be made by those skilled in the art without departing from the principle and spirit of this invention, and these changes and modifications are within the scope of this invention.
