Heavy hammer pre-pressurization device
Technical field
The present invention relates to a kind of auxiliary processing device, especially a kind of heavy hammer pre-pressurization device.
Background technology
At present, using the carbon element workshop at aluminium, when vibrating forming machine is produced anode block, mainly is that anode paste is placed in the die sleeve, again by the suitable pressure vibration moulding that acts on weight on the thickener surface.Weight directly influences looking of moulded products to the specific contact pressure of thickener and sees density and molding time, so require weight must reach certain weight, aluminium is recommended specific contact pressure q=0.055~0.06MPa with the carbon element make-up machine now, weight weight 5500~6000kg, therefore the weight of weight itself is bigger, the vibrational system oscillating mass is bigger, cause system vibration inertia to strengthen, oscillation power consumption is big, to equipment itself, the hazard of vibration aggravation of basis and building, and because weight is freely to lie on the thickener surface by own wt, be in the free vibration state in the vibration processes, so the density error up and down of the anode block vertical cross section after the moulding is bigger, the glance coal in the anode paste flies upward everywhere in the forming process simultaneously, influence environment, pollute.
Summary of the invention
The objective of the invention is to, a kind of heavy hammer pre-pressurization device is provided.This device can reduce the weight of weight, reduces the oscillating mass of system, and by the mouth that gathers dust of device glance coal is carried out the centralized collection processing, avoids environmental pollution, and is simple in structure, easy to implement.
Technical scheme of the present invention is: weight (15) top is connected with the weight axis of guide (16) lower end, connecting plate (3), rubber pneumatic bag (5), connecting plate (7), connecting plate (8), rubber pneumatic bag (6) is connected in series with connecting plate (14) and passes the weight axis of guide (16), weight (15) top is connected with connecting plate (3), rubber pneumatic bag (5) bottom is connected with connecting plate (3), rubber pneumatic bag (6) top is connected with connecting plate (14), Connection Block (10) passes the weight axis of guide (16) and is connected with connecting plate (14) and is fixed on case (2) top, Connection Block (10) is provided with air admission hole (12), air admission hole (12) passes connecting plate (14) and is communicated with rubber pneumatic bag (6), and seal receptacle (13) passes the weight axis of guide (16) and is connected with Connection Block (10); Case (2) top is connected with Connection Block (10), and case (2) both sides are provided with hydraulically operated fixture (1).
Described heavy hammer pre-pressurization device, fairlead (9) pass the weight axis of guide (16) and are connected with connecting plate (7).
The two ends, bottom of aforesaid case (2) are provided with alignment pin (17).
Aforesaid heavy hammer pre-pressurization device is provided with black box (4) between connecting plate (3) and weight (15), connecting plate (7) and connecting plate (8), Connection Block (10) and connecting plate (14), Connection Block (10) and seal receptacle (13) and seal receptacle (13) and the weight axis of guide (16).
Compared with prior art, the present invention increases rubber pneumatic bag and in pneumatic mode weight is pressurized on the anode paste in the die sleeve, be pressurized on the weight with a suitable power by the pressure of regulating rubber pneumatic bag, make weight obtain a suitable specific contact pressure, the power that rubber pneumatic bag is pressurized on the weight realizes by regulating rubber pneumatic bag air pressure, and this power is internal force in whole vibrational system, do not consume oscillation power, therefore under the situation that guarantees the weight specific contact pressure, can reduce the weight of weight, reduce the oscillating mass of system, and by the mouth that gathers dust that installs glance coal is carried out centralized collection and handle, avoid environmental pollution, simple in structure, easy to implement.

The specific embodiment
Embodiment: the structure of heavy hammer pre-pressurization device as shown in Figure 1, weight 15 tops are connected with the weight axis of guide 16 lower ends, connecting plate 3, rubber pneumatic bag 5, connecting plate 7, connecting plate 8, rubber pneumatic bag 6 is connected in series with connecting plate 14 and passes the weight axis of guide 16, weight 15 tops are connected with connecting plate 3, rubber pneumatic bag 5 bottoms are connected with connecting plate 3, rubber pneumatic bag 6 tops are connected with connecting plate 14, Connection Block 10 passes the weight axis of guide 16 and is connected with connecting plate 14 and is fixed on case (2) top, Connection Block 10 is provided with air admission hole 12, air admission hole 12 passes connecting plate 14 and is communicated with rubber pneumatic bag 6, and seal receptacle 13 passes the weight axis of guide 16 and is connected with Connection Block 10; Case 2 tops are connected with Connection Block 10, and case 2 both sides are provided with hydraulically operated fixture 1, and the two ends, bottom of case 2 are provided with alignment pin 17; Be provided with black box 4 between connecting plate 3 and weight 15, connecting plate 7 and connecting plate 8, Connection Block 10 and connecting plate 14, Connection Block 10 and seal receptacle 13 and seal receptacle 13 and the weight axis of guide 16.
When work, the precharge device depends on weight 15 and descends under the effect of make-up machine hoist cylinder, until lying in molding machine die cover upper surface, the accuracy of its position guarantees that by alignment pin 18 this moment, hydraulically operated fixture 1 was opened, and die sleeve and case 2 are buckled together firmly, meanwhile, weight continues to descend under the effect of hoist cylinder until the anode paste surface, and this moment, rubber pneumatic bag fed compressed air, finished and can carry out the operation of other operation of make-up machine, work finishes, the rubber pneumatic bag venting, hydraulically operated fixture 1 is opened, at this moment, the action of make-up machine hoist cylinder, weight rises, and extracts the precharge device and get back to initial bit, promptly finishes a working cycles.All black boies 4 guarantee the sealing of whole device.Entire exercise is carried out interlocked control near switch by being arranged on the equipment.Be pressurized on the weight 6 with a suitable power by the pressure of regulating rubber pneumatic bag, make weight 6 obtain a suitable specific contact pressure, this power is synchronized with the movement weight 6 and shake table with opposite direction when vibration simultaneously, thereby dwindle the whole vertical cross section of anode block density error and the vibration moulding time up and down after the moulding, to meet the requirements of the uniformity and packing, electric conductivity and roasting quality behind the raising baking cathode carbon block, rubber pneumatic bag is pressurized to power on the weight and can reaches 3 ~ 7t and do not wait, and all can realize by regulating rubber pneumatic bag air pressure.
