Description
Technical field
The invention belongs to the field of power equipment technology of cutting equipment.
Background technique
Often can use cutter in factory, general cutter is mainly used in the sheet materials such as cutting plastic bag, rubber tape, metal foil and metal composite foils, and it is formed primarily of cutting knife, Qie Tai and drive unit, and material is placed on by cutting knife on conveyer belt, completes blank.Existing cutter drive unit is generally air cylinder driven, its shortcoming is: existing cylinder adopts pressurized air as power source, particularly cylinder is when driving blade cuts material, output speed due to cylinder is comparatively large and be difficult to control, blade is caused " firmly to contact " with material, damage is caused to blade and material, in addition, blade controls by cylinder with during rollback stretching out, because the compression ratio of air is large, the output stability of cylinder is poor, pauses or situation that speed changes suddenly when may there is blade moving.
Summary of the invention
The invention is intended to provide that output stability is high, the cutter drive unit of controlled speed.
Technological scheme in this programme is: cutter drive unit, comprise cylinder block, cylinder piston and cylinder piston rod is provided with in cylinder block, an air ports is respectively established at the two ends of cylinder block, described cylinder block and a cylinder block are arranged in parallel, be provided with oil cylinder piston and cylinder piston rod in this cylinder block, this cylinder piston rod is connected by connecting rod with cylinder piston rod; This cylinder block is provided with circulating pipe, and this circulating pipe is provided with the ball valve that control oil pipe opens and closes and the speed control rod regulating running of hydraulic power oil speed in oil pipe, it is interior and movable linearly that speed control rod radially inserts oil pipe.
The beneficial effect of this programme is: a cylinder block in parallel on cylinder block, overcome the problem of pressurized gas output temperature difference, this is because the compression ratio of hydraulic oil is very little, because the output stability of oil cylinder is higher, cylinder piston rod and cylinder piston rod are connected into overall take-off lever by connecting rod, the output stability of this drive unit can be improved; In addition, in the circulating pipe of oil cylinder, speed control rod is set, the position of adjustment speed control rod, then can realize the flow control to oil cylinder hydraulic oil, effectively can control the speed of the retraction of cylinder piston rod, about damping is formed to cylinder, and then the overall rollback speed of accessory drive, on the other hand, when oil cylinder and cylinder export simultaneously, cylinder piston rod will overcome the resistance of hydraulic oil, so also can reduce the output speed of this cutter drive unit, prevent blade from " firmly contacting " with material, damage is caused to blade and material.
Further, be provided with hollow airway in described speed control rod, this air flue communicates with the piston cavity in cylinder block, is controlled the position of speed control rod, the flow velocity in circulating pipe of regulator solution force feed by the air turnover amount of cylinder, and then controls the speed of oil cylinder piston.
Further, connecting rod, perpendicular to cylinder piston rod and cylinder piston rod, ensures being synchronized with the movement of cylinder piston rod and cylinder piston rod.
Further, described connecting rod and cylinder piston rod, cylinder piston rod are bolted, and connect more firm.
Accompanying drawing explanation
Fig. 1 is the structural representation of cutter drive unit embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: 1-cylinder block, 2-cylinder piston, 3-cylinder piston rod, 4-first air ports, 5-second air ports, 6-cylinder block, 7-circulating pipe, 8-oil cylinder piston, 9-cylinder piston rod, 10-connecting rod, 11-ball valve, 12-speed control rod.
Embodiment is substantially as shown in Figure 1: cutter drive unit, comprise cylinder block 1, cylinder block 1 comprises cylinder body, protecgulum and bonnet, with cylinder piston 2 and cylinder piston rod 3 in the piston cavity of cylinder body, with the O RunddichtringO with cylinder body contact internal walls on the perisporium of this cylinder piston 2, cylinder piston rod 3 stretches out along the cylinder delivery outlet of bonnet.Protecgulum has and the first air ports 4, bonnet has the second air ports 5, first air ports 4 and the second air ports 5 all communicates with piston cavity.
Cylinder block 6 has been installed in parallel in the side of cylinder block 1, the front end and back end of this cylinder block 6 is communicated with by a circulating pipe 7, with oil cylinder piston 8 and cylinder piston rod 9 in piston cavity in cylinder body, with the O RunddichtringO with cylinder body contact internal walls on the perisporium of this oil cylinder piston 8, cylinder piston rod 9 stretches out along cylinder block 6 rear end of bonnet.
Cylinder piston rod 3, cylinder piston rod 9 are all fixed by bolt with connecting rod 10, and this connecting rod 10 is perpendicular to cylinder piston rod 3 and cylinder piston rod 9.
With ball valve 11 on oil cylinder circulating pipe 7, this ball valve 11 can controlled circulation oil pipe 7 startup (being namely that hydraulic oil in circulating pipe 7 starts to flow) and close (be namely hydraulic oil stop flowing) in circulating pipe 7, this circulating pipe 7 is driven the speed control rod 12 with radially inserting this circulating pipe 7, this speed control rod 12 dip section is the mobile flow section getting final product controlled circulation oil pipe 7 in circulating pipe 7, thus the flow velocity of hydraulic control oil.As shown in the figure, with hollow airway in speed control rod 12, this hollow airway is by pipeline access cylinder first air ports 4.During use, cylinder piston rod 3 and cylinder piston rod 9 bounce back simultaneously, pressurized gas is got rid of from the first air ports 4, Partial shrinkage gas enters speed control rod 12 and promotes speed control rod 12 moves, circulating pipe 7 flow section is diminished, the retraction speed of cylinder piston rod 9 is reduced, thus drives the speed of the cylinder piston rod 3 be connected with cylinder piston rod 9 also to tell somebody what one's real intentions are, the blade rollback that so can prevent cylinder piston rod 3 fast fallback from causing is unstable.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
