Abstract
The utility model discloses a saw cutting device, comprising a portal type frame, a main axle box, a feed turn-screw, a saw cutting variable-frequency electric device, a feed reducer, a feed variable-frequency device for driving the feed variable-frequency electric device; a saw cutting variable-frequency device for driving the saw cutting variable-frequency electric device; a control circuit connected with the feed variable-frequency device and the saw cutting variable-frequency device, wherein a warning is set out when the current value obtained by current signal send by the feed variable-frequency device and the saw cutting variable-frequency electric machine exceeds the preset value. When the current value of the feed variable-frequency device and the saw cutting variable-frequency electric machine exceeds the preset value, the power supply frequency of the variable-frequency device and the saw cutting variable-frequency device is reduced by the control circuit, therefore the feed and the saw cutting speed is reduced. In addition, the operation of the lead screw is limited by mounting a limit device. The saw cutting device effectively solves the problem that the lead screw is easily damaged and the life of the saw cutting device is prolonged.
Description
Technical field
The utility model relates to a kind of sawing machine, relates in particular to a kind of copper ingot sawing machine that has protection system.
Background technology
Slab ingot high speed sawing unit is a sawing copper alloy ingot specialized apparatus, and its effect one is excision cast gate and bottom; The 2nd, long ingot casting sawing is become the ingot blank of scale; The 3rd, (the supplied materials casting blank specification is generally 150mm～290mm * 500mm～1050mm * 4400mm～8500mm) to the excision casting defect.Existing sawing machine core is made up of planer-type frame, main spindle box, main feed screw, main shaft variable-frequency motor, feeding variable-frequency motor, feeding reductor etc.During the sawing machine operation, saw blade runs up with the linear velocity of 10m～40m/sec, the steel construction main spindle box travels forward along the speed of rack rail with 100mm～1500mm/min (saw blade near ingot casting before reduce to the sawing feed speed by unloaded feed speed), the blank that has clamped is carried out sawing, and cooling fluid is cooled off the saw blade otch and is lubricated in the time of cutting.Wherein, main feeding ball-screw is that gyration is converted into rectilinear motion, and the promotion saw blade seesaws and carries out the sawing operation.And the ball-screw bearing is made up of screw rod and ball, and function is to change into rectilinear motion with rotatablely moving, and has high accuracy, invertibity and high-efficiency characteristics concurrently, and the endless form of ball is the circulation conduit formula.Ball tube will occur after this leading screw moves several classes continuously and break, faults such as leading screw screw rod wearing and tearing have only the return-to-factory reparation, need the long period approximately, cause producing carrying out smoothly.
The reasons for the above problems have 2 points: 1. harder by the sawing material, saw blade efficient is low, as operating personnel the unreasonable then ball-screw of speed is set and is subjected to larger side to power, causes easy to wear the breaking of pearl pipe.2. blade wear as in time not changing, causes the cutting-rate low velocity slow, and same ball-screw is subjected to larger side to power, causes easy to wear the breaking of pearl pipe.
The utility model content
In view of this, the purpose of this utility model provides a kind of sawing machine of protecting saw blade and saw blade feed system.
Above-mentioned purpose realizes by following proposal:
A kind of sawing machine, it comprises planer-type frame, main spindle box, feeding turn-screw, sawing variable-frequency motor, feeding variable-frequency motor, feeding reductor, it is characterized in that, described sawing machine also comprises:
The feeding frequency converter, it drives described feeding variable-frequency motor;
The sawing frequency converter, it drives described sawing variable-frequency motor;
Control circuit, it connects described feeding frequency converter and sawing frequency converter, when the current signal that provides according to described feeding frequency converter and sawing frequency converter knows that electric current surpasses predetermined value, gives the alarm.
Sawing machine according to above-mentioned is characterized in that, on described planer-type frame spacing contact is installed, when described feeding drive lead screw moves to spacing contact place, and described control circuit feed-disabling motor.
Use sawing machine of the present utility model; when because material is too hard or the difficult feeding electric current that causes of feeding is excessive; because when blade wear causes the sawing electric current excessive; can reduce feed speed or sawing speed automatically; and when screw mandrel runs to spacing contact place; feeding stops automatically, thereby can effectively protect screw mandrel.
Fig. 1 is the structural representation that has the sawing machine of protection system of the present utility model.
Description of drawings
Referring to Fig. 1, sawing machine of the present utility model comprises gantry type frame 1, main spindle box 2, sawing variable-frequency motor 3, feeding variable-frequency motor 4, feeding reductor 5, feeding turn-screw 6, feeding frequency converter 7 and sawing frequency converter 8. Feeding frequency converter 7 drives into to variable-frequency motor 4, and sawing frequency converter 8 drives sawing variable-frequency motor 3. Feeding frequency converter 7 preferred power are 5.5KW.
The specific embodiment
This sawing machine also comprises control circuit 9, and it connects feeding frequency converter 7 and sawing frequency converter 8, when the current signal that provides according to feeding frequency converter 7 and sawing frequency converter 8 knows that electric current is crossed predetermined value, gives the alarm.Usually, be because material 12 is too hard or the difficult feeding electric current that causes of feeding is excessive, cause the sawing electric current excessive owing to work as blade wear.
In addition, when the electric current of sawing variable-frequency motor 4 or feeding variable-frequency motor 5 surpassed predetermined value, control circuit 9 can also reduce the frequency of supply of feeding frequency converter 7 and sawing frequency converter 8, thereby reduced feeding and sawing speed.
In addition, spacing contact 10 and 11 are installed on the planer-type frame 1, when feeding drive lead screw 3 moves to spacing contact place, control circuit 9 feed-disabling variable-frequency motors 7.Preferably, 100mm place before leading screw forward-reverse terminal point, the installation site of spacing contact.
Claims (2)
1. sawing machine, it comprises planer-type frame, main spindle box, feeding turn-screw, sawing variable-frequency motor, feeding variable-frequency motor, feeding reductor, it is characterized in that, described sawing machine also comprises:
