Abstract
The utility model relates to a steel ball cold holder. The holding ball mechanism comprises a crankshaft-driven connecting rod and a main slider; wherein, a punch is arranged in the front of the main slider; the mounting end of the punch is clamped in the main slider; a connecting rod is a universal round head rod and the end of the connecting rod is spherical; the main slider is provided with corresponding spherical pits, so the movement is smooth and flexible, the fit clearance due to abrasion can be adjusted conveniently, the accuracy of steel ball can be improved, and the maintenance becomes easy without need for the replacement of parts. The utility model has the advantages of high precision, stability, reliability, 0.05mm and lower deviation per 100 balls, steady and flexible movement, low failure rate, simple operation and convenient maintenance, so that the abrasion gap can be conveniently eliminated timely, the production efficiency is improved greatly, 8 to 10 machines can be operated per capita, the noise can be reduced and the physical and mental health of the operator is benefited.
Description
(1) technical field
The utility model relates to the steel ball production equipment that uses in the bearing processing, particularly a kind of ball cold header.
(2) background technology
Steel ball belongs to a vitals of bearing, and the preceding working procedure that the steel ball cold heading operation is produced as steel ball has directly determined steel ball production cost and quality.The main transmission of ball cold header by main driven by motor big belt pulley, again with transmission of power to bent axle, the power of bent axle is orderly passes to three mechanisms: drive master slider by bent axle combination, connecting rod and move back and forth and realize the punching press action; Drive the blank cam by blank dish, pull bar and realize the blank action; Adjust the moving feeding mechanism of dribbling by charging and realize intermittent feeding.The close fit of three parts is formed a complete steel ball cold heading machine, with the steel wire of certain specification by feeding, cut-out, cold-heading up to steel ball blanks, as shown in Figure 1.The cold headers majority that China now adopts belongs to the product that former Soviet Union technology is produced, and has following shortcoming:
1. existing cold headers poor stability, the fault rate height cause the adjustment maintenance of equipment to take the plenty of time, but operating equipment platform number is few per capita, has only 3～5, and production efficiency is low.
2. existing cold headers low precision, institute's rammer steel ball quality instability, the about 0.1mm of the dimensional discrepancy of per hundred steel balls, its main cause is that wear and tear in machines is serious after the long-term operation, the gap occurs and can't in time adjust and eliminate, and causes the complete machine precise decreasing.For example, all adopt linkage between bent axle and the master slider, can't eliminate wearing clearance, can only change by adjusting; The drift locking mode is bolt, impulsive force acquires a certain degree and occurs sideslip difference problem easily.In order to guarantee the quality of steel ball, have to add the big steel ball allowance, so both wasted raw material, increased workload for again later process (photosphere), cause steel ball production waste of electric energy.
3. existing cold headers noise is big.Because existing cold headers low precision, part cooperates not tight with part, so cause the complete machine noise big, gives the operator physically and mentally healthy formation injury.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and the ball cold header of a kind of precision height, reliable and stable, easy to maintenance, the high and low noise of productivity ratio is provided.
The utility model is achieved by the following technical solution:
Ball cold header of the present utility model, its ball upsetting machine structure comprises connecting rod, the master slider that is driven by bent axle, and the front end of master slider is provided with drift, and the installation end of drift is connected in the master slider, its special character is: connecting rod is the universal ball end connecting rod, its end is spherical in shape, and master slider is provided with corresponding with it spherical pit, and therefore motion steadily, flexibly, be convenient to adjust the fit clearance that produces because of wearing and tearing, improve the precision of steel ball, and easy to maintenance, do not need renewal part.
Ball cold header of the present utility model in order having eliminated because of the not firm sideslip problem that occurs of impulsion locking, to accompany the adjusting swash plate, and to be provided with the follower bolt of pushing down the adjusting swash plate between master slider and the lathe bed.Follower bolt generally is connected on the lathe bed.
Ball cold header of the present utility model in order to eliminate wearing clearance, recovers precision, improves the quality of steel ball, accompanies briquetting between a side of drift and the master slider, accompanies wedge between the opposite side of drift and the master slider, and is provided with the adjusting bolt of pushing down wedge.Regulating bolt generally is connected on the drift.
Ball cold header of the present utility model in order to improve the rub proofness of lathe bed, prolongs the service life of lathe bed, also accompanies wear-resisting guide rail between master slider and the lathe bed, and guide rail is fixed on the lathe bed.
The beneficial effects of the utility model are, the precision height is reliable and stable, the deviation of per hundred steel balls is less than 0.05mm, steadily flexibly, fault rate is low, and is simple to operate in motion, easy to maintenance, be convenient in time eliminate wearing clearance, improved production efficiency greatly, can operate 8～10 per capita, platform has reduced noise, helps operator's physical and mental health.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Width of cloth figure is a structural representation of the present utility model.
Fig. 1 is a kinematic scheme, and Fig. 2 connects the situation front view for master slider, and Fig. 3 is the master slider right view, and Fig. 4 is the master slider cross-sectional view, and Fig. 5 is the drift upward view, and Fig. 6 is the right view of drift.
Among the figure, 1 bent axle, 2 connecting rods, 3 master sliders, 4 drifts, 5 regulate swash plate, 6 follower bolts, 7 briquettings, 8 wedges, 9 regulate bolt, 10 guide rails, 11 lathe beds.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Connecting rod 2 between the ball cold header of the present utility model, bent axle 1 and master slider 3 adopts the universal ball end connecting rods to be connected, as Fig. 2, shown in Figure 3.Accompany between one side of master slider and the lathe bed 11 and regulate swash plate 5, the big end of regulating swash plate is provided with follower bolt 6, as shown in Figure 4.Wedge 8, briquetting 7 are adopted in the locking of drift 4, with bolting briquetting are arranged between a side of drift and the master slider, accompany wedge between the opposite side of drift and the master slider, and the big end of wedge is pressed with regulates bolt 9, sees Fig. 5, Fig. 6.Also accompany wear-resisting guide rail 10 between master slider and the lathe bed, guide rail is fixed on the lathe bed 11, sees Fig. 4.Punch die is upper and lower, left. and screw is all adopted in right adjustment, and is flexible.
