Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of rod material automatic cutting machine, particularly about the cutting mechanism of rod material automatic cutting machine.
Background technology
In the part processing process, often a bar need be cut into plurality of sections, process again.Cutting machine is exactly the process equipment commonly used that is used to cut bar.
At present, advanced is automatic gas cutting machine.As " rod material automatic cutting machine that the slip positioner is arranged " that Chinese patent 03271904.3 provides, it is made up of lathe bed, transmission system, diced system and feed system, and transmission system regulates the length of required cutting; Feed system is delivered to the cut place with bar; By retaining head bar is blocked and to make it can not continue to move forward; At this moment, by cylinder the blade on the diced system is cut bar again.The efficient of whole cutting process is higher.But cutting machine moves up and down the cutting bar by cylinder control blade, though that cylinder promotes the mode speed that piston rod moves up and down is very fast, exists that precision is not high, device structure is than complicated problems.
In addition, do not support the mechanism of bar in the cut place, bar tilts easily, causes that its otch is irregular, Cutting Length is inconsistent.
Summary of the invention
The purpose of this utility model is at the existing the problems referred to above of existing automatic gas cutting machine, and a kind of cutting mechanism of rod material automatic cutting machine is provided, and makes it have the characteristics simple and reasonable, that cutting accuracy is high.
The purpose of this utility model can realize by following technical proposal: the cutting mechanism of this rod material automatic cutting machine comprises motor and the blade that is fixed on the machine shaft, blade is in discharging place of cutting machine, it is characterized in that, this cutting mechanism also comprises a vertical connecting rod that is provided with and can moves up and down with respect to fuselage, the upper end and the motor of connecting rod are connected, and the lower end roof pressure is in the edge of a rotary cam.
The cutting mechanism of this rod material automatic cutting machine is that the rotation by cam makes roof pressure move up and down at the connecting rod at cam edge, thereby the blade that makes the motor that is connected in small end move rotation cuts bar.
In the cutting mechanism of above-mentioned rod material automatic cutting machine, be provided with a back-up block in discharging place of cutting machine, back-up block is fixed on the fuselage, and bar is from the top process of back-up block, the side of the plane of blade next-door neighbour's back-up block.
Back-up block is played a supporting role to bar, and bar is moved horizontally, and the position can not tilt, and is concordant with the otch that guarantees cutting, the cutting accuracy height.
In the cutting mechanism of above-mentioned rod material automatic cutting machine, the top cross-section of described back-up block is V-shaped.
In the cutting mechanism of above-mentioned rod material automatic cutting machine, cross bar of horizontally set in the fuselage of rod material automatic cutting machine, one end and the fuselage of cross bar are hinged, the other end contacts with the cam edge, and between cross bar middle part and fuselage, be provided with a spring, be close to the edge of cam in the end of the effect sheer pole of spring; A depression bar vertically is set in fuselage, and there is a strut kong that supplies bar to pass through the upper end of depression bar, and the lower end of depression bar is connected with cross bar.
Said mechanism is the rotation by cam, makes cross bar drive depression bar, depression bar is pushed down or is unclamped bar by strut kong.Particularly, when farthest, cam edge goes to the connecting rod place, move on to highest point on the blade; Simultaneously, the contacting with the end of cross bar the most nearby of cam edge, depression bar moves to highest point on also.At this moment, bar is by strut kong, and blade does not contact with bar yet.When the cam edge turn to the connecting rod place the most nearby the time, blade moves down, and by the motor rotating blade bar is cut.Meanwhile, the farthest at cam edge contacts with the end of cross bar, and cross bar is moved down together with depression bar, and strut kong is in the state of pushing down bar.Like this, the fixed-site of bar, blade can very stably cut bar.
In the cutting mechanism of above-mentioned rod material automatic cutting machine, the end of described cross bar is provided with a pulley, and pulley is close to the edge of cam.Pulley plays the rubbing action that reduces between cross bar and the cam, helps the rotation of cam.
Compared with prior art, this cutting mechanism is controlled moving up and down of blade by mechanically operated structures such as cam and connecting rods, and it is simple and reasonable, reliable.
Discharging place at bar is provided with back-up block and depression bar, and support is arranged at the bottom of bar, pushes down bar at the moment depression bar of cutting, make bar in cutting process position stability, shake or skew can not take place, thereby make the otch of bar concordant, Cutting Length is accurate.

The specific embodiment
As depicted in figs. 1 and 2, the cutting mechanism of this rod material automatic cutting machine is installed in the fuselage 1 of cutting machine.It comprises parts such as connecting rod 2, cross bar 3, cam 4, back-up block 5, spring 6, depression bar 7 and pulley 8.
As shown in Figure 2, cam 4 is connected in the fuselage 1, and cam 4 rotates by a driven by motor.Connecting rod 2 vertically is provided with, and fuselage 1 is stretched out in the upper end of connecting rod 2, is fixed together with motor 10.The lower end of connecting rod 2 is in the fuselage 1, and its end roof pressure is in the edge of cam 4.
A cross bar 3 is arranged in fuselage 1, cross bar 3 horizontally sets, an end is provided with pulley 8, and the other end and fuselage 1 are hinged.The two ends of spring 6 are connected in respectively on fuselage 1 and the cross bar 3.Cross bar 3 its pulley 8 under the effect of spring 6 is close to the edge of cam 4.Therefore, when cam 4 rotated, cross bar 3 also and then swung up and down.
On cross bar 3, also be connected with a depression bar 7.In the present embodiment, depression bar 7 vertically is provided with, and its lower end and cross bar 3 are hinged, and fuselage 1 is stretched out in the upper end.As shown in Figure 5, in the upper end of depression bar 7 a strut kong 7a is arranged, bar 12 passes this strut kong 7a.When cross bar 3 swung up and down, depression bar 7 also and then moved up and down, and made strut kong 7a leave or push down bar 12.
As shown in Figure 3 and Figure 4, a back-up block 5 is being fixed in discharging place on fuselage 1, and a V-shaped groove 5a is arranged at the top of back-up block 5.Bar 12 is by V-shaped groove 5a.Back-up block 5 plays the effect of supporting bar 12.
As shown in Figure 2, the pay-off by cutting machine is delivered to the cut place with bar 12.In carrying bar 12 processes, at first be that the strut kong 7a of blade 9 and depression bar 7 is in the position of moving, bar 12 is by the V-shaped groove 5a of strut kong 7a and back-up block 5, and bar 12 front ends move to retaining 11 place of being fixed on the fuselage 1.Be subjected to retaining 11 to stop that bar 12 can't move forward.Then, along with the rotation of cam 4, connecting rod 2 and cross bar 3 move down, and blade 9 and depression bar 7 are also and then moved down.At this moment, back-up block 5 supports bar 12, and depression bar 7 is pushed down bar 7, and 9 pairs of bars 12 of blade cut.At last, after cutting is finished, move on blade 9 and the depression bar 7, return back to initial position.Constantly repeat said process, just can realize cutting automatically the purpose of bar 12.
