The rear end of described movable branching rod by T type spare pin joint at the fixed bar that is fixed on the support.

Described first chain upper end connects the cutting rotating shaft in the cutting mechanism.

Described pedal end is equipped with roller, and roller is attached on the roller plate and works.

Described work top one side fixedly has the blow tank under oblique.

Has the backing plate of putting workpiece for pad on the described work top.

After adopting such scheme, the utlity model has many beneficial effects:

At first the utility model has been broken the form of traditional small-sized hand-press cutting machine, and cutting mechanism is positioned on the work top, and cut form is changeable, cooperates its cutting mechanism and transmission mechanism are ingenious simultaneously, and control mode is simple, and is easy to use.

Description of drawings

Fig. 1 is the utility model preferred embodiment structural representation one;

Fig. 2 is the utility model preferred embodiment structural representation two.

The specific embodiment

By reference to the accompanying drawings, preferred embodiment is described in further details to the utility model.

Desk-top cast gate disconnects machine, and the parts that are mainly concerned with comprise workbench 1, cutting mechanism 2, transmission mechanism 3.

Workbench 1 is the pallet that metal material is made, and comprises that work top 11 and work top 11 bottoms are used for the support 12 of supporting, and present embodiment medium-height trestle 12 comprises leg 13 and is arranged on the crosspiece 14 of strengthening connection between the leg.

Cutting mechanism 2 mainly comprises gripper shoe 21, bracing frame 22, motor 23, cutting rotating shaft 24, cutting blade 25 in the present embodiment.Motor 23 and cutting rotating shaft 24 are installed in rear end and the front end of gripper shoe 21 respectively, connect by belt 26, make motor 23 drive cutting rotating shaft 24 rotation works, an end of cutting rotating shaft 24 has just been installed cutting blade 25, cutting rotating shaft 24 is rotated, and drives cutting blade 25 work that runs up.Outside cutting blade 25, also has guard shield 27.

The below pin joint of gripper shoe 21 is on bracing frame 22, and its pin joint point is relatively near the rear end of gripper shoe 21.The rearward end of gripper shoe 21 is connected with spring 4, spring 4 down, the lower end of spring 4 is connected on the rear crosspiece 14 of workbench 1, is used for resetting after the cutting.

In addition, cutting has been placed backing plate 15 on work top 11 surfaces for convenience, and workpiece to be cut can be placed on the backing plate 15 and cut.Simultaneously, be provided with blow tank 16 in a side of work top 11, blow tank 16 entrances flush with work top 11, and whole oblique having a down dip is similar to the structure of slide.The workpiece that cuts down can be along blow tank 16 landing dischargings.

Transmission mechanism 3 mainly is the oscilaltion of controlling cutting blade 25 by pushes pedals 31, and the parts that are mainly concerned with comprise pedal 31, movable branching rod 32, U-shaped bar 33, second chain 34.

Movable branching rod 32 is metal rods, its front end is connected with pedal 31, the rear end forms pin joint, free to rotate, be by fixing a fixed bar 35 at the rear of support 12 crosspiece 14 in the present embodiment, by a T type spare with movable branching rod 32 pin joints on fixed bar 35, make that like this movable branching rod 32 can be along with pin joint point freely rotates.On pedal 31 and the position that ground contacts roller 36 is installed, is not worn in order to protect roller 36 surfaces, put a roller plate 37 at roller 36 underlays.

The horizontal part of U-shaped bar 33 is set on the hollow pipe 38, and hollow pipe 38 is fixed on the crosspiece 14 in support 12 the place aheads, and it is free to rotate that U-shaped bar 33 is arranged in hollow pipe 38.One end of U-shaped bar 33 is connected with cutting rotating shaft 24 on the work top 11 by first chain 5, can spur by first chain 5 and cut rotating shaft 24 and land downwards.The other end of U-shaped bar 33 is connected with movable branching rod 32 by second chain 34.

During the utility model work, the operator piles up workpiece on backing plate 15, push down on the pedal 31, after movable branching rod 32 down rotates, spur second chain 34 down, angle of whole upset downwards of U-shaped bar 33, in this simultaneously first chain 5 also left behind, will cut rotating shaft 24 together with the cutting that descends simultaneously of whole gripper shoe 21.After cutting is finished, remove external force on the pedal 31, this moment, movable branching rod 32 did not have pulling force to act on second chain 34, therefore gripper shoe 21 is by the elastic force of spring 4, left behind in the rear end, front end rises and replys, and such first chain 5 is along with the rising of cutting rotating shaft 24 is raised, the integral body of U-shaped bar 33 is upwards turned round an angle, and this moment, second chain, 34 natures were carried movable branching rod 32.

Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
