Abstract

The utility model discloses an edge cutting device of a rotary cutter, which belongs to the technical field of processing and manufacturing. The edge cutting device consists of an upper mould, a lower mould, an upper mould cutter block, lower mould cutter blocks, a driving block, sliding blocks and a positioning block, wherein the upper mould and the lower mould are used as an integral bracket of the edge cutting device; and the upper mould cutter block arranged at the lower part of the upper mould is used for realizing the function of downward cutting. Four groups of driving modules are connected with four groups of lower mould cutter blocks through the sliding blocks, the driving block is used for converting a downward force of the upper mould into a planar force, and the lower mould cutter blocks are driven by the sliding blocks to carry out 90-DEG circular motion so as to finish the accurate and complete cutting and edge planing of circular or square products; meanwhile, the lower mould cutter blocks are driven to realize automatic reset. The modules have good integrity and high coordinating property, so that the products can be accurately carried out; the upper cutter block and the lower cutter blocks can work at the same time, so that the forming can be realized in one step, the edge cutting precision is high and the efficiency is high; therefore, the edge cutting device can be widely used for the processing and forming of such square or circular hardware products as a micro motor, a decorative ring for a camera lens and the like.

Description

A kind of rotary cutter trimming device

Technical field

The utility model belongs to the processing and manufacturing technical field, is specifically related to a kind of rotary cutter trimming device.

Background technology

Large-scale production utilization along with engineering goods and mould, especially handware product such as micro motor and camera lens case ring, its device that carries out processing and fabricating has been proposed requirements at the higher level, and Design of device not only need be considered its numerical control, accuracy, more need consider the feature of its globality.

In current handware product processing and fabricating, mode is slightly made in general employing turning, milling, drilling etc., though they can be processed product effectively, the production efficiency that has is low, quality is unstable, the manufacturing cost that has is higher, and burr after the processing are big, appearance is bad for cutting of having.Along with the progress of industrial technology, the whole incoordination when these lathes are produced appears gradually, therefore need make improvements, so that reply industrial expansion trend.

Summary of the invention

For addressing the above problem, the utility model provides a kind of novel rotary cutter trimming device, is used for product processing, has Total tune, adapts to the close trim machine-shaping of square, circular handware products such as micro motor and camera lens case ring.

The technical solution of the utility model is: a kind of rotary cutter trimming device, its structure is made up of upper die and lower die, patrix cutter piece, lower die cutter piece, drive block, slide block, locating piece, patrix cutter piece is done perpendicular cuts, the drive block power that patrix is downward is converted to the power on plane, driving the lower die cutter piece by slide block does to rotatablely move all around, cut off circular or square product, and drive lower die cutter piece automatically resets.

Described upper and lower mould is whole appliance stand, and counterdie is fixed during work, and patrix drives the cutter piece and moves downward.

Described patrix cutter piece links to each other with patrix, is circular or square side cut, and otch is downward, finishes first procedure to product boring.

Described lower die cutter piece is positioned on the counterdie, and totally 4 groups, edge of a knife burr, every group of circular motion of doing 90 ° finished the accurate complete cut-out to product, and digs the limit, can automatically reset.

Described drive block is positioned at counterdie, and totally 4 groups, projection also can be done and move both vertically, and drives slide block to lower compression during work and stretches, and automatically reset.

Described slide block is connecting drive block and lower die cutter piece, is circular motion so that drive block drive lower die cutter piece is done.

Described locating piece is positioned at counterdie, in order to finish the accurate location to product.

The beneficial effects of the utility model are: install each module and have globality and harmony, can accurately locate product, two cutter pieces act on simultaneously up and down, one-shot forming, side cut precision height can increase substantially production efficiency, and features simple structure, it is low that cost is set, and can be widely used in the machine-shaping of square, circular handware products such as micro motor and camera lens case ring.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The product component embodiment that Fig. 2 produces for the utility model.

Among the figure, 1 is patrix; 2 is counterdie; 3 is patrix cutter piece; 4 is the lower die cutter piece; 5 is drive block; 6 is slide block; 7 is locating piece.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of rotary cutter trimming device, with patrix (1), counterdie (2) integral support as device, patrix cutter piece (3) is positioned at the bottom of patrix, finish downward cutting function, driver module (5) is connecting lower die cutter piece (4) by slide block (6), and the three all is positioned at counterdie (2) and locates, locating piece (7) is in the medium position of counterdie, is used for product is accurately located.

The specific embodiment of the present utility model is as follows.

As Fig. 1, a kind of rotary cutter trimming device, when work, at first raw material are put into lower die cutter piece (4) top, location back patrix (1) drives patrix cutter piece (3) and cuts downward vertically, bore circle or square opening, 4 groups of driver modules (5) are stressed simultaneously, to lower compression, drive slide block (6) and rotate, when slide block (6) rotates the downward power of driver module (5) is converted to the power on plane, drive 4 groups of lower die cutter pieces (4) and do 90 ° circular motion, finish accurate complete cut-out, and dig the limit product, every group automatically resets after independently finishing side cut, after all modules are finished successively, can once finish the moulding of product, as Fig. 2.

The utility model can be used for the moulding of handware products such as circle, square micro motor and camera lens case ring, and production operation is simple, and Total tune is strong, and the production efficiency height can extensively promote the use in the close trim field.
