Abstract
The utility model discloses a steel ball cold header which comprises a shearing mechanism, a cold heading mechanism and a feed mechanisms between each mechanism; the steel ball cold header is characterized in that a rolling mechanism is arranged between the shearing mechanism and the cold heading mechanism; the rolling mechanism consists of an upper rolling die and a lower rolling die which make relative movement and are respectively provided with a shaping notch. As the rolling process of a stock is added before cold heading, the stock entering the cold heading mechanism is ensured to be a cylinder with a round angle or a chamfer angle or a cylinder in other special shapes; besides, the stock does not have raw edges or burrs, thus leading the plastic deformation of the stock of the steel ball to be good, leading the stress strain distribution to be uniform, improving the quality and the qualification rate of the stock of the steel ball and reducing the production cost of the stock of the steel ball. Besides, as the shape of the stock entering the cold heading mechanism is regular, a cold heading die is uniformly stressed during a punching process, thus prolonging the service life of the cold heading die.
Description
Technical field
The utility model relates to a kind of steel ball manufacturing equipment, especially relates to a kind of ball cold header.
Background technology
Steel ball cold heading processing is the production link that steel ball blanks is provided for the steel ball grinding, and the quality quality of steel ball cold heading processing directly influences the quality of steel ball finished product.Existing steel ball blanks cold upsetting production technology is: feeding (bar) → cut off → feeding (cylinder blank) → cold-heading (punching press) → steel ball blanks.Its implementation procedure in ball cold header is (as Fig. 1): motor-driven feeding runner 9 is sent bar 6 to along the guide hole axial direction of guide plate 8, after bar 6 stretches out certain-length, the shearing die 7 of cutting mechanism is cut off bar 6 becomes blank 3, and blank 3 is delivered to the punch die place of cold-heading mechanism, shearing die 7 is return, upper trimming die push rod 5 stretches out, blank 3 is headed into down in the punch die 2, upper trimming die 4 and following punch die 2 will be sheared bar and strike out steel ball blanks, following punch die push rod 1 ejects punch die with steel ball blanks, carries out next one circulation again.
In using existing steel ball blanks production technology and cold headers production steel ball blanks process, because bar is in the process of cutting off, can deform and can not guarantee that blank is a cylinder, and blank has burr or burr, so can cause blank in the process of punching press cold-heading, plastic deformation is bad, the ess-strain skewness causes the steel ball blanks defectiveness after the punching press, and is folding etc. as local underfill, material, the steel ball blanks qualification rate is lower, and the difficult quality of steel ball blanks is guaranteed.Also cause cold-heading mould discontinuity in punching course in addition, influence the service life of cold-heading mould.
The utility model content
The applicant has carried out research and has improved at above-mentioned technical problem, a kind of steel ball cold heading technique that can prolong die life, raising steel ball blanks cold-heading quality and qualification rate is provided, and a kind of ball cold header of implementing this steel ball cold heading technique is provided.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of ball cold header comprises the feed mechanism between cutting mechanism, cold-heading mechanism and each mechanism, and device has the stranding cutting mechanism between above-mentioned cutting mechanism and the cold-heading mechanism.
Above-mentioned stranding cutting mechanism is to do go up rubbing with the hands of relative motion to cut mould and rub with the hands down and cut mould, and it is respectively equipped with the shaping notch.
Above-mentioned shaping notch is " Qian " shape notch, and the base angle of notch both sides is chamfering or the fillet that changes from small to big.
Above-mentioned shaping notch is " U " shape notch, and the base angle of notch both sides is chamfering or the fillet that changes from small to big.
Technique effect of the present utility model is: cut processing owing to increased the stranding of blank before cold-heading, the blank that assurance enters cold-heading mechanism is to have the cylinder of fillet or chamfering or the cylinder of other special shapes, and there are not burr or burr, make the plastic deformation of steel ball blanks good, ess-strain is evenly distributed, improve the quality and the qualification rate of steel ball blanks, reduce the production cost of steel ball blanks.In addition, because it is regular to enter the blank shape of cold-heading mechanism, the cold-heading mould is stressed even in punching course, prolongs the service life of cold-heading mould.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 2, the feeding runner 10 of motor-driven feed mechanism is sent bar 20 along the guide hole axial direction of guide plate 11, after bar stretches out certain-length, the shearing die 13 of cutting mechanism is cut off bar 20, and the blank 21 that will shear is delivered to the end of feed mechanism push rod 12, push rod 12 heads into the stranding of going up of rubbing cutting mechanism with the hands with blank 21 and cuts mould 14 and rub the inner chamber place of cutting mould 15 down with the hands, last stranding is cut mould 14 and is descended stranding to cut mould 15 and makes blank 21 predeformation in its shape chamber do relative motion, and predeformation blank 21 delivered to the cold heading die place by feed mechanism (not illustrating in the drawings), the push rod 16 of upper trimming die 17 stretches out, blank 21 is headed into down in the punch die 18, upper trimming die 17 and following punch die 18 strike out steel ball blanks with blank 21, following punch die push rod 19 ejects down punch die 18 with steel ball blanks, carries out next one circulation again.
Shown in Fig. 3,4,5, the stranding cutting mechanism is cut mould 14 and is descended stranding to cut mould 15 by last stranding and constitutes, and upper and lower stranding is cut and done relative motion between the mould, and their reciprocating motion can be by drivings such as existing cam mechanism, crankshaft connecting rod system or cylinders.In the present embodiment, last stranding is cut mould 14 and is descended stranding to cut mould 15 and has " Qian " shape notch, the base angle of notch both sides is chamfering or the fillet that changes from small to big, be described chamfering or fillet from the A section to the C section gradually never to having and progressively enlarging, last stranding is cut mould 14 along rubbing butt with the hands to moving, and rubs blank 21 with the hands be extruded onto the C section right-hand member place from A section left end.The effect of A section is mainly guiding, and revises shapes for the cylinder blank 21 of distortion, adjusts blank 21 and cuts position in the mould in upper and lower stranding; The effect of B section is mainly pre-stranding and cuts, and provides transition for cylinder blank 21 gradually becomes the cylinder that has chamfering or fillet, and blank 21 is rubbed with the hands cuts out less chamfering or fillet; The effect of C section is mainly improves chamfering or rounded shapes.Blank 21 end surface shape gradually change in whole process, are become the blank 21 (as Fig. 7,8) of band chamfering or fillet by cylinder.
Above-mentioned stranding cutting mechanism also can be rubbed the cylinder that cuts out special shape with the hands, and as the cydariform cylinder, use has as the upper and lower stranding of " U " shape notch of Fig. 6 cuts mould, can rub the blank 21 (as Fig. 9) that cuts out the swelled column shape with the hands.
