Description
Technical field
The utility model relates to a kind of sandbox hold down gag.
Background technology
Present most enterprises is when production copper piece casting, and the technological process of production should be the liquid copper in the sandbox of producing shaped under cast molten condition mostly, and liquid copper passes through cooling finished product in sandbox.In the process of producing, liquid copper is after injection sandbox, in the process of cooling, certain expansion can be produced, and sandbox is substantially all two sandboxes closes up, therefore all can presses a foundary weight now on sandbox, utilize the pressure of foundary weight, guarantee that the die cavity in sandbox can not be out of shape because of expansion when liquid copper cooling, finally cause the copper product of moulding by casting off quality.
Owing to needing the extruding of foundary weight, therefore people need constantly to be changed one by one by foundary weight and put up, and constantly go to be pressed in above new sandbox, carrying is wasted time and energy, extra increase labour is needed to carry out work, increase production cost that like this can be larger.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of sandbox hold down gag, change the mode of original a dead lift foundary weight into cylinder pressing down, can guarantee the pressure extruding sandbox on the one hand, another conveniently can guarantee that being extruded voluntarily of sandbox stabilizes.
For achieving the above object, the utility model provides following technical scheme: a kind of sandbox hold down gag, it is characterized in that: comprise frame, described frame is equipped with the transport tape for transmitting sandbox, described frame is provided with the driving mechanism for driving described transport tape, be provided with pressure cylinder above described transport tape, the piston rod of described pressure cylinder is provided with the pressing plate for clamping sandbox, and described pressure cylinder is connected with fixed mount.
The utility model is set to further: described transport tape comprises chain, and described chain is equipped with some rectangular placement plates, described placement plate is fabricated from iron, and described driving mechanism comprises motor, and motor is by gear drive chain drive.
The utility model is set to further: described pressure cylinder quantity is 3, and linearly array, the spacing between described pressure cylinder is consistent with described placement plate width.
The utility model is set to further: described pressure cylinder is cylinder and is connected with extraneous air pump.
Compared with prior art, the utility model has the advantage of, change the mode of original a dead lift foundary weight into cylinder pressing down, can guarantee the pressure extruding sandbox on the one hand, another conveniently can guarantee that being extruded voluntarily of sandbox stabilizes.And coordinate the structure of upper transport tape, the automation transfer of sandbox in transfer process can be ordered about, such people only need sandbox to be placed on transport tape from one end, through the transmission of transport tape, to copper metallurgy boiler side, sandbox is pushed down by cylinder pioneer dynamic pressure plate, copper liquid under molten condition injects in sandbox by workpeople, after the pressure one end time continued, after waiting setting of expanding, cylinder piston-rod displacement, sandbox entered transport tape transmission and was sent to down in one manufacturing procedure.Can allow the comparatively automation after simple transformation of the casting process of whole copper product like this, can labor cost be saved, also can enhance productivity simultaneously.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model sandbox hold down gag embodiment.
Reference numeral: 1, frame; 21, chain; 22, plate is placed; 3, pressure cylinder; 31, pressing plate; 32, fixed mount.
Detailed description of the invention
With reference to Fig. 1, the utility model sandbox hold down gag embodiment is described further.
A kind of sandbox hold down gag, comprising frame 1, described frame 1 being equipped with the transport tape for transmitting sandbox, described frame 1 is provided with the driving mechanism for driving described transport tape, and transport tape is placed on the smelting furnace side of molten copper.Described transport tape comprises chain 21, and described chain 21 is equipped with some rectangular placement plates 22, described placement plate 22 is fabricated from iron, place plate 22 fine arrangement between any two, when transmission sandbox, each block is placed on plate 22 and is placed a sandbox, guarantees that sandbox can stablize transport.Described driving mechanism comprises motor, and motor is by gear drive chain 21 transmission, and it is common that motor to drive in transmission structure very, is applied on multiple transmission line.
Be provided with pressure cylinder 3 above described transport tape, the piston rod of described pressure cylinder 3 is provided with the pressing plate 31 for clamping sandbox, and pressing plate 31 is oblong-shaped, and pressing plate 31 is fixed on the piston rod of pressure cylinder 3.Described pressure cylinder 3 is connected with fixed mount 32, and on fixed mount 32, effect can be fixed on above transport tape in order to ensure pressure cylinder 3 to there will not be deviation.Described pressure cylinder 3 quantity is some, and linearly array, spacing between described pressure cylinder 3 is consistent with described placement plate 22 width, that guarantees each pressure cylinder 3 correspondence one can place plate 22, when pressing sandbox, each pressure cylinder 3 can be pinned being placed on the sandbox placed on plate 22, displacement of being expanded by sandbox when preventing liquid copper from pouring into a mould.Multiple pressure cylinder 3 can be guaranteed disposablely can press multiple sandbox, enhances productivity.
The workflow of this device is as follows, and an empty sandbox correspondence is placed on one is placed on plate 22 by artificial, start transport tape, arrive after formulating position, pressure cylinder 3 utilizes pressing plate 31 to be pushed down by sandbox, then artificial by liquid copper cast as in sandbox.After waiting for one end time, pressure cylinder 3 return, transport tape drives the sandbox poured into a mould to continue transmission forward.
Described pressure cylinder 3 is cylinder and is connected with extraneous air pump.Pressure cylinder 3 can be cylinder also can be oil cylinder, the travel speed of oil cylinder is slightly slow, and larger pressure can be produced, originally the pressure used is needed and need not be very large, therefore cylinder can be utilized, cylinder stroke speed, pressure stability, the requirement of pressing can be met completely, can raise the efficiency greatly.Cylinder is connected with air pump, by the opening and closing of control circuit control cylinder, and the operation that can be convenient for people to.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
