Abstract

The utility model discloses a manual steel bar cutter with an outer shell transmission mechanism. An electrical motor is installed on one end of the transmission mechanism, and fixed blades and cutting blades are arranged on the other end. Handles are arranged on the outer shell of the transmission mechanism which use a hydraulic mechanism in which a cam wheel fuel pump is arranged. A working oil chamber is connected with the cam wheel fuel pump. A piston positioned on the front end of the working oil chamber is connected with the cutting blades. The utility model has the advantages of simple structure, convenient operation, and large force of cutting generated, which is especially suitable for automotive work.

Description

Portable steel bar cutter
The utility model relates to the machine tool technology field, is the be parallel to each other shear of blade cuts of motion of a kind of utilization, specifically is to say, is the shear that a kind of usefulness is hydraulically powered, have only a motion blade.Can also say, be a kind of hand-held metal sheet slitting equipment.
These device structure complexity are normally finished in present bar cutting with fixed, heavy special use cut-out equipment, inefficiency, especially can't motor-driven operation, make its purposes be subjected to considerable restraint, and troublesome poeration, therefore, in many occasions, people utilize hammer-shears to cut off reinforcing bar, and method is cut off in such craft, time-consuming, take a lot of work, require great effort, but also can't cut off thicker reinforcing bar.
The purpose of this utility model provides a kind of simple in structure, easy to operate portable bar cropper.
Technical solution of the present utility model is: a kind of portable bar cropper, a transmission mechanism of being with shell is arranged, and an end of transmission mechanism is equipped with motor, and the other end is equipped with fixed blade and movable blades, on the shell of transmission mechanism handle is housed.
Transmission mechanism in the utility model adopts hydraulic mechanism.
A cam oil pump is arranged in the hydraulic mechanism in the utility model, and a working oil chamber links to each other with the cam oil pump, and the piston that is positioned at the working oil chamber front end links to each other with movable blades.
Cam oil pump in the utility model has the oil pump chamber, and an eccentric shaft by driven by motor is arranged in the oil pump chamber; A bearing holder (housing, cover) is contained on the eccentric shaft, and can make eccentric rotary along the oil pump cavity wall; One is divided into two-part spacing block with the oil pump chamber and is contained on the oil pump cavity wall; Pass in and out oil duct in addition on the oil pump cavity wall and the chamber is interlinked to the outside.
Be equipped with on piston in the utility model or the working oil chamber sidewall in order to control the easing valve that a wasteway opens and closes.
Piston nose in the utility model is equipped with reset components.
On the handle in the utility model motor control switch is housed.
Rest pad is equipped with in the preceding lower end of transmission mechanism shell in the utility model.
Wasteway in the utility model communicates with oil input channel on the oil pump chamber.
The utility model has the advantages that: compact conformation is simple, volume is little, in light weight, is particularly suitable for motor-driven operation, and easy for operation, the shearing force of generation is big, can cut off the reinforcing bar of ten, 20 mm dias easily, high efficiency.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a kind of portable bar cropper structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 1, Fig. 2 have described an embodiment of the present utility model.Motor 11 drives eccentric shaft 33 rotations, two ends of eccentric shaft 33 are equipped with bearing 15 and 19 respectively, bearing 15,19 supporting positioning actions, and bearing 16 relative bearings 15,19 are set for the eccentric, eccentric shaft 33 and bearing 16 interference fit, eccentric shaft 33 drives bearing 16 and rotates together, the direction of arrow among Fig. 2 is direction of rotation, when bearing 16 eccentric rotations, high pressure chest 21 volumes are dwindled gradually, form high pressure, hydraulic oil enters in the oil cylinder 34 by pressing oil duct 10, promotes piston 20 and moves right, the cutting blade 3 that links to each other with piston 20 is moved to the ledger-plate 2 that fixes with right engine housing 1, thereby make the materials such as reinforcing bar that are between two blades be subjected to very strong shearing force and block, on the other hand, when bearing 16 is pressed direction rotation shown in the arrow among Fig. 2, oil sucting cavity 22 volumes are constantly enlarged, form negative pressure, oil is sucked from oil suction road 7 by low-pressure cavity 35, thereby form loop.Left and right plane sealing gasket 13; the 17th, solve bearing 16 and inhaling; press the flat seal problem in the oily process; it can select suitable encapsulant for use; sealing ring 6; the 4th, with the sealing problem that solves in the piston 20 axially-movable processes; spring 5 is when the back piston usefulness that automatically resets of cutting off the electricity supply; when hypertonia; cone valve 27 moves right; hydraulic oil just directly leads to low-pressure cavity 35 through wasteway 32; thereby play the effect of the whole device of protection; spring 28 is a holddown spring; regulator bolts 31 is used for promoting the thrust that spring base 29 reaches regulating spring 28; 30 is " O " RunddichtringO, adopts above-mentioned parts can control the oil pressure of whole hydraulic closed circuit system, is cylinder body at the left end of right engine housing 1; right-hand member is the ledger-plate fixed mount, built-in motor control switch 9 in the Square handle 8 on engine housing 1.Left side engine housing 12 has constituted a complete cam oil pump with middle body 14 and right body 1, cage ring 18, there is a high-low pressure spacing block 25 to separate between high pressure chest 21 and the oil sucting cavity 22, high-low pressure spacing block 25 is compressed by holddown spring 24, stopping up 23 is the technology plug, high-low pressure spacing block 25 by the hydraulic oil of high pressure chest 21 through 26 superchargings of spacing block supercharging road, make it tightly touch bearing 16 surfaces, and keep its seal request.In right body 1 preceding lower end rest pad 36 is housed, when operating, to play supporting role.
