Abstract

A sheet shearing machine belonging to the machinery field consists of an upper part and a lower part, wherein the lower part consists of a motor, a speed reducer and a lower blade shaft arranged on a lower machine frame, the lower blade shaft is provided with a lower friction wheel and a lower circular blade, and the upper part consists of an upper blade shaft arranged on an upper machine frame, an upper friction wheel and an upper circular blade arranged on the upper blade shaft. The upper machine frame and the lower machine frame are integrated with each other and are in the form of scissors. The rims of the upper friction wheel and the lower friction wheel are in contact with each other, and the upper and lower circular blades are also in contact with each other. One end of a sheet to be sheared is clamped between the two friction wheels and the two circular blades, when the motor transmits a torque to the lower blade shaft via the speed reducer, the lower friction wheel rotates accordingly to drive the sheet to move, consequently the sheet drives the upper friction wheel and the upper circular blade to rotate, and finally the sheet clamped between the two circular blades are sheared. The sheet shearing machine can shear a sheet with a thickness less than or equal to 2 mm both in vertical and horizontal directions and the sheet to be sheared is not limited regarding length and width, thereby being particularly suitable for small-scale machining enterprises with various types of products and small lot.

Description

A kind of thin plate plate shearing machine

1, technical field: a kind of thin plate plate shearing machine of the present utility model belongs to mechanical field, relates in particular to the cutting equipment in a kind of panel beating.

2, background technology: present domestic plate shearing machine majority is lock formula and hydraulicdriven swing-type plate shears, also has the only a few disc plate shearer, it is to restricted by shear material width, structure is simplified inadequately, big and heavy, acquisition expenses height, and numerous small-sized machine processing enterprise purchases this kind equipment exists use cost height, problem that utilization rate of equipment and installations is low.

3, summary of the invention: the purpose of this utility model is that a kind of thin plate plate shearing machine will be provided, it is simple in structure, the transmission uniqueness, complete machine is gently little, the manufacturing use cost is low, the plate that is tailored is not had dimensional requirement, and portraitlandscape all can be cut out, and is very suitable for the assorted little small-sized machine processing enterprise in batches of product and cuts out thickness and use when 2mm and following plate.

The purpose of this utility model is achieved in that plate shearing machine is made up of two parts up and down, the bottom is made up of the motor, reductor, the bottom knife axle that are installed on the frame, be equiped with down friction pulley and lower disc blade on the bottom knife axle, top is formed by being installed in upper slitter bobbin on the frame and the last friction pulley on the upper slitter bobbin and last cylinder blade.Last lower bearing bracket is a disjunctor, is scissor, and the one side is a downward inclined-plane, and opposite side is a platform.Upper and lower friction pulley wheel rim is in contact with one another, and upper and lower cylinder blade also is in contact with one another.To be tailored the plate end clips is held between two friction pulleys and two cylinder blades, when motor when reductor is passed to the bottom knife axle with moment of torsion, following friction pulley rotation can drive plate and move ahead, thereby drive upward friction pulley and the rotation of last cylinder blade by plate, the plate that is clamped between two cylinder blades can be sheared out.

Owing to carry out such scheme, just realized cutting out thickness when 2mm and following plate, portraitlandscape all can be cut out, and the plate that is tailored is not subjected to the purpose of length and width size restrictions, and the business equipment use cost is reduced greatly.

4, description of drawings: concrete structure of the present utility model is provided by following examples and accompanying drawing

5, the specific embodiment:

Embodiment: shown in Fig. 1～4, the thin plate plate shearing machine is made up of two parts up and down, and the bottom is made up of the motor, reductor and the bottom knife axle 5 that are installed on the lower bearing bracket 8, is equiped with down friction pulley 6 and lower disc blade 4 in the key connecting mode on the bottom knife axle 5.Top is by being installed in the upper slitter bobbin 2 on the upper spider 9 and forming with last friction pulley 7 and last cylinder blade 1 that the key connecting mode is installed on it.Last lower bearing bracket is a disjunctor, is scissor, and the one side is a downward inclined-plane, and opposite side is a platform.Upper and lower friction pulley 7,6 is cast-iron wheel, and periphery is surrounded by rubber layer, and two wheel rims are contact up and down mutually, and upper and lower cylinder blade 1,4 is contact up and down mutually also.

When cutting out operation, to be tailored plate 3 end clips and be held in 1,4 of upper and lower friction pulley 7,6 and upper and lower cylinder blades, when motor when reductor passes to bottom knife axle 5 with moment of torsion, following friction pulley 6 rotates thereupon, can drive plate 3 moves ahead, thereby rotated by plate last friction pulley 7 of 3 drives and last cylinder blade 1, the plate 3 that is clamped in 4 on last cylinder blade 1 and lower disc blade can be sheared out.Two blocks of slope material that shearing is opened on as shown in Figure 5 lower bearing bracket triangle bonding pad separately, one goes out along the bevelled sidesway of frame, another piece has a sidesway of platform to go out along frame.

Claims

1, a kind of thin plate plate shearing machine, form by two parts up and down, it is characterized in that: the bottom is made up of the motor, reductor and the bottom knife axle that are installed on the lower bearing bracket, be equiped with down friction pulley and lower disc blade in the key connecting mode on the bottom knife axle, top is made up of the last friction pulley and the last cylinder blade that are installed in the upper slitter bobbin on the upper spider and be installed on this in the key connecting mode, upper and lower friction pulley periphery all is surrounded by rubber layer, two wheel rims are in contact with one another, and upper and lower cylinder blade also is in contact with one another.

2, plate shearing machine as claimed in claim 1 is characterized in that: going up lower bearing bracket is a disjunctor, is scissor, and the one side is the inclined-plane, and opposite side is a platform.
