Abstract
The utility model relates to a cold-drawing die for a toothed shaft, which is provided with a die body; a drawing die hole is formed on the die body and is a toothed through hole with the cross section the same as the end surface of the toothed shaft; the toothed through hole is a circular-arc-tooth-shaped through hole; more than two circular arc teeth are uniformly distributed on the circumference; and a charge hole for the blank of the toothed shaft to be drawn to pass through and enter the drawing die hole is formed on one side of the drawing die hole, and a discharge hole for the discharging of the formed toothed shaft is formed on the other side of the drawing die hole. The cold-drawing die is used for processing the toothed shaft and enables the toothed shaft to be formed in one step in a cold-drawing processing method, thereby realizing efficient processing and ensuring the quality of the product.
Description
Technical field
The utility model relates to the cold-drawn processing technique field, especially a kind of toothed shank cold drawing die.
Background technology
Often need make the deformed steel of some special shapes in mechanical manufacturing field, toothed shank as shown in Figure 1, six circle-arc teeth are evenly distributed on the circumference, process such toothed shank, need utilize lathe just can finish through the multiple tracks cutting process usually, precision is not very high, can cause the circle-arc tooth deviation, and efficient is not high, wastes time and energy, and product quality can not guarantee.Cold-drawn processing is to rely on mould to control metal flow, forms the product of required cross sectional shape by the transfer of metal volume, does not produce waste cut materials in drawing process, so we need a kind of cold drawing die to realize the cold-drawn processing of toothed shank.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of toothed shank cold drawing die is provided, by the cold-drawn method for processing, make the toothed shank one-shot forming, realize high efficiency processing, and can guarantee the quality of product.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of toothed shank cold drawing die, has die ontology, offer draw hole on the die ontology, draw hole is the cross section profile of tooth through hole identical with the toothed shank end face, the profile of tooth through hole is arc toothed through hole, and plural circle-arc tooth is evenly distributed on the circumference.
Described draw hole one side is provided with can be for the toothed shank blank for the treatment of drawing by entering the charging hole of draw hole, and the draw hole opposite side is provided with can be for the discharge opening of molding gear oblique crank Z discharging.
The toothed shank blank for the treatment of drawing is entered draw hole from charging hole, utilize the cold-drawn method for processing, the toothed shank blank pushes the drawing moulding in the profile of tooth through hole, pull out from the discharge opening of cold drawing die, obtains the toothed shank of moulding.If the precision of toothed shank does not reach requirement, can carry out the secondary cold-drawn.
The beneficial effects of the utility model are: the utility model has designed a kind of toothed shank cold drawing die, be used to process this class of toothed shank special, the difficult deformed steel of finishing of common process, draw hole is arranged between charging hole and the discharge opening, the mould compressive resistance is stronger, drawing is not yielding, and the toothed shank blank pushes drawing in the profile of tooth through hole, makes the toothed shank one-shot forming, the realization high efficiency is processed, and can guarantee the quality of product.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the end view of toothed shank;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the A-A cutaway view of Fig. 2;
Wherein: 1. die ontology, 2. charging hole, 3. discharge opening, 4, draw hole, 5. toothed shank
The specific embodiment
Be illustrated in figure 1 as the toothed shank 5 of required processing, have six along the equally distributed circle-arc tooth of circumference.
The toothed shank cold drawing die shown in Figure 3 as Fig. 2, have die ontology 1, offer draw hole 4 on the die ontology, draw hole 4 is the cross section profile of tooth through hole identical with the toothed shank end face, the profile of tooth through hole is arc toothed through hole, and six circle-arc teeth are evenly distributed on the circumference.
Draw hole 4 one sides are provided with can be for the charging hole 2 of toothed shank blank by entering draw hole 4 for the treatment of drawing, and draw hole 4 opposite sides are provided with can be for the discharge opening 3 of molding gear oblique crank Z 5 dischargings.
The toothed shank blank for the treatment of drawing is entered draw hole 4 from charging hole 2, utilize the cold-drawn method for processing, the toothed shank blank pushes the drawing moulding in the profile of tooth through hole, pull out from the discharge opening 3 of cold drawing die, obtains required toothed shank 5.If the precision of toothed shank 5 does not reach requirement, can carry out the secondary cold-drawn.
Utilize the cold-drawn method for processing to make toothed shank 5 one-shot formings, realize high efficiency processing, do not have the hot-working link, energy savings consumption, and guarantee product quality.
With above-mentioned foundation embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from the utility model technological thought.Technical scope of the present utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
