Specific embodiment
With reference to the accompanying drawings of the specification and embodiment, specific embodiments of the present invention are described in further detail:
Referring to figs. 1 to a kind of pre-roll machine of sheet metal shown in 13, including rack 1, the top of rack 1 is equipped with support plate
1a, support plate 1a are equipped with positioning mechanism, clamp system and roll bending mechanism, and positioning mechanism is equipped with for carrying out to thin plate 3
The positioning table 4a of positioning, clamp system are set there are two clamp arm 5a, and two clamp arm 5a are located at positioning table 4a side, and clamp arm 5a's is transversal
Face shape is equipped with clamp arm driving mechanism, clamp arm driving mechanism is for driving two clamp arm 5a in semi-circular between two clamp arm 5a
It moves towards or the edge of thin plate 3 is clamped or is unclamped backwards to movement, roll bending mechanism includes pressure roller 6a and pressure
Roller driving mechanism, pressure roller driving mechanism is for driving pressure roller 6a to rotate by the center of circle of the central point of two clamp arm 5a of clamped condition
One circle, the movement starting point of pressure roller 6a are arranged below positioning table 4a and clamp system middle, and clamp system is by the side of thin plate 3
Moving so that thin plate 3 carries out bending deformation by mould of two clamp arm 5a by pressure roller 6a after being clamped at.
The upper surface of positioning table 4a is equipped with locating piece 4b, and locating piece 4b is adjacent with clamp system perpendicular to positioning table 4a's
One edge;Thin plate 3 is placed on positioning table 4a by artificial or mechanical mode, and thin plate 3 is along perpendicular to locating piece 4b long
The direction sliding of degree line is slided after being connected on locating piece 4b, then along the length line of locating piece 4b until two clamp arm of insertion
Between 5a, locating piece 4b is wherein playing the role of being that an edge of thin plate 3 is enable to dock completely with two clamp arm 5a
Above and keep its edge parallel with the axis of clamp arm 5a, so that thin plate 3 is capable of forming cylindrical shape after being bent, avoids because thin
Put not the cylinder both ends out-of-flatness for just leading to be formed after deformation in 3 position of plate.
Two clamp arm 5a and positioning table 4a close one end are equipped with snap openings a 5a1, the snap openings 5a1 of two clamp arm 5a
It is oppositely arranged, thin plate 3 is slided along the length line of locating piece 4b until being connected to the end face of the vertical direction of two snap openings 5a1
On;And then the length for being clamped position to thin plate 3 is defined.
Clamp arm driving mechanism includes the support arm 5b between two clamp arm 5a, is all provided on the intrados of two clamp arm 5a
Have several guide rod 5a2, each guide rod 5a2 corresponded on support arm 5b and is equipped with a guide sleeve 5b1, guide rod 5a2 with lead
To set 5b1 sliding plug cooperation, the axis of guide rod 5a2 is perpendicular to horizontal plane, by guide rod 5a2 and guide sleeve 5b1 to folder
Arm 5a is fixed and motion guide, and a shaft being rotatably assorted with it, the both ends difference of shaft are additionally provided on support arm 5b
Equipped with first gear 5c and the first synchronizing wheel 5d, it is equipped on the intrados of two clamp arm 5a and is engaged with first gear 5c
Rack gear 5a3, two rack gear 5a3 are each perpendicular to horizontal plane and the two is symmetrical arranged along the radius of first gear 5c vertical direction;
Clamp arm driving motor 5e is additionally provided on support arm 5b, in the second synchronizing wheel that clamp arm driving motor 5e output shaft is equipped with and shaft
The first synchronizing wheel 5d pass through synchronous belt pass connection;The positive and negative rotation of clamp arm driving motor 5e drives first gear 5c positive and negative rotation, into
And two rack gear 5a3 is driven linearly to move, so that two clamp arm 5a is moved toward one another or is pressed from both sides backwards to movement to thin plate 3
Tight or release.
The power supply line of clamp arm driving motor 5e cannot be it is fixed, clamp system rear is arranged in roll bending mechanism,
Pressure roller 6a is fixed on the second gear 6d at clamp system rear, if power supply line is arranged on nothing if clamp system rear
The movement of pressure roller 6a can be hindered by doubting, and if power supply line is arranged in front of clamp system, it is contemplated that demoulding, thin plate 3
It needs to extract from front after deformation, be arranged in front undoubtedly can cause to hinder to demoulding;Therefore by clamp arm driving motor 5e's
Power supply line be designed to can fast insert-pull form, be particularly equipped with and clamp arm driving motor 5e electricity in the front end of support arm 5b
Property connection socket 7a, rack 1 is equipped with the plug 7b of one with socket 7a cooperation, plug 7b driving mechanism is equipped with inside rack 1,
Plug 7b driving mechanism includes lifting device and horizontally moving device, and lifting device is used to driving plug 7b two clamp arm 5a's
Front position vertical lifting is in sustained height, its height after plug 7b decline with socket 7a when plug 7b moves to highest point
Lower than the height of clamp system, horizontally moving device is mounted on the top of lifting device, and the plug 7b, which is fixed on, to be moved horizontally
On the output end of device, horizontally moving device is for driving plug 7b to move horizontally in insertion socket 7a, plug 7b and power supply
Connection, lifting device and horizontally moving device can use cylinder or electric pole.
Its working principle is that the initial state of two clamp arm 5a is arranged to open configuration, when work, by artificial or
Thin plate 3 is inserted between two clamp arm 5a by the mode of person's mechanical arm, by a control switch, keeps lifting device task driven horizontal
Fixed plug 7b rises to and socket 7a sustained height, then horizontally moving device driving plug 7b on mobile device output end
Socket 7a is inserted into as clamp arm driving motor 5e power supply, two clamp arm 5a is moved toward one another and clamps thin plate 3, pressure roller 6a is to clamp shape
The central point of two clamp arm 5a of state is that center of circle rotation is turned around so that thin plate 3 carries out bending deformation by mould of two clamp arm 5a, change
Waiting for a period of time after shape makes thin plate 3 shape, and clamp arm driving motor 5e drives two clamp arm 5a backwards to mobile by thin plate 3 after setting
It unclamps, horizontally moving device driving plug 7b is extracted from socket 7a, and lifting device drives horizontally moving device to be decreased below
Workpiece is extracted from two clamp arm 5a by way of artificial or mechanical arm, then repeatedly one is opened by the height of clamp system
The step of beginning;The sheet metal pre-roll operation of automation is realized with this.
