Technical Field

The invention belongs to the field of machinery, and particularly relates to a full-automatic aluminum cover top raised and raised character milling integrated machine.

Background

The common raised characters (patterns) of the aluminum bottle cap are formed by rolling and extruding the raised characters on the side surface (cylindrical surface) of the aluminum bottle cap in a rolling manner, and then a special character milling machine is used for milling the raised characters to form bright surfaces, so that the attractiveness of the bottle cap is improved.

With the development of packaging in the wine industry, the requirement of milling bright surfaces of raised characters (patterns) on the top plane of a bottle cap appears in the market. The plane bulge at the top of the existing bottle cap is formed by stamping through pressure equipment, and the production efficiency is difficult to improve.

Specifically, the reduction motor 23 drives the small chain wheel 18 to rotate and then drives the large chain wheel 13 to rotate, the large chain wheel 13 drives the main shaft 12 to rotate, the main shaft 12 drives the two slide rail seats 3 to rotate, the linear slide rail pairs 20 are arranged on the slide rail seats 3, the mandrel seat 4 is fixed on the linear guide rail pairs 20, the push-pull plate 9 is arranged on the mandrel seat 4, the other end of the push-pull plate 9 is provided with two cam driven bearings 19, and the two cam driven bearings 19 are tightly attached to the curved bosses of the left cam 2 and the right cam 10 (see fig. 3).

The slide rail seat 3 rotates to drive the push-pull plate 9 to move, and further drives the cam driven bearing 19 on the push-pull plate 9 to do longitudinal linear motion according to the curve track of the cam boss (see fig. 3).

The pattern on the top plane of the bottle cap can be extruded when the convex curves of the left cam 2 and the right cam 10 drive the push-pull plates 9 on both sides to press the male die and the female die on the mandrel 05 on both sides together (see figure 4).

The thickness of the top plane of the workpiece (aluminum bottle cap) is about 0.2 mm, and the extrusion depth of each pair of male die and female die can be adjusted by adjusting the eccentric amount of the cam driven bearing 19.

The function of the eccentric shaft 17 is to lock the mandrel base 4 and prevent the mandrel base 4 from moving backwards when the cam is pressed (see fig. 3).

The workpiece flows to the material receiving disc 6 through the slideway, and the material receiving disc 6 is arranged on the flange sleeve 7. When the main shaft 12 rotates to drive the material receiving disc 6 to rotate, a workpiece falls into the groove of the material receiving disc 6, and when the material receiving disc 6 rotates clockwise (see figure 4) to 0 point, the cam rolling bearing 19 on the boss of the left cam 2 is driven along the curve of the boss, so that the push-pull plate 9 drives the mandrel seat 4 to push the mandrel 5 into the workpiece hole, and the cover pushing action is started. Similarly, the right cam 10 drives the related components to start to move towards the center, when the take-up pan 6 rotates to 4 points, the left cam 2 and the right cam 10 simultaneously drive the related components to extrude the male die 81 and the female die 82 together to complete the raised characters (patterns), and then the related components continue to rotate to 5 points to complete the extrusion raised character formation.

And after the extrusion is finished, the extrusion process is operated to 9 points to begin character milling. The milled aluminum scraps fall into a scrap collecting hopper 21 below and are collected by a dust collection device 30. When related elements pass through 12 points along the linear boss of the left cam 2, the mandrel 5 retreats, the cover-removing action starts under the action of the blocking piece 15, the mandrel 5 stops retreating when the linear boss continues to reach 15 points, the cover-removing action is completely finished, and the blocking piece 15 is installed on the cover-removing plate 16 and plays a role in cover-removing.

The capping (feeding) was started when the run reached 22 o' clock. At the same time, the right cam 10 drives the relevant element to go back after 5 points. When 9 o 'clock, the backward movement is completed to make room for the milling cutter 22 to mill characters (see fig. 2), and when 9 o' clock, the milling cutter 22 completes the character milling process, the milling cutter 22 is installed on the milling cutter spindle 26, the high-speed motor 24 drives the upper chain wheel 28 to rotate through the chain wheel 27 installed at the shaft end, and then drives the milling cutter spindle 26 to make the milling cutter 22 rotate at high speed. The right cam 10 repeats the above actions when running to the 0 point.

The invention integrates the raised character process and the character milling process into a whole, simplifies the equipment structure to make the equipment more compact, changes the stamping action of stamping the top character into the non-impact action, and adopts the extrusion motion forming formed by the cam curve motion track. The punching noise is eliminated, the stability of the equipment is improved, and the service life of the equipment is prolonged. The intermittent motion of the original production process is changed into continuous non-intermittent motion, and the production efficiency is stabilized to more than 200 pieces per minute.

After the convex character working procedure and the convex character milling working procedure are combined into an integrated machine, the working procedure is transferred after convex character raising to save a separator and a feeding slideway in the convex character milling process, the pollution to workpieces in the process of queuing and feeding again is reduced, the waste products generated by collision and extrusion in the sorting process of the separator in secondary queuing and feeding are reduced, and the occupied area of equipment is also reduced.
