Abstract
The invention provides a lower die of a bending machine and an auxiliary mechanism of the lower die. The lower die is provided with at least two V-shaped grooves. The auxiliary mechanism is fixed to two sides of one V-shaped groove, and comprises a movable positioning plate, a spring, a lining, a guiding screw, a base and rollers, the guiding screw is perpendicularly connected with the movable positioning plate, the lining is arranged between the guiding screw and the movable positioning plate, the guiding screw penetrates through the spring to press the spring under the movable positioning plate, the bottom of the guiding screw is fixed onto the base, the rollers are disposed on two sides of the top of the other V-shaped groove, and inclined planes of the other V-shaped groove are tangent to or intersected with circumferential surfaces of the rollers. The lower die of the bending machine and the auxiliary mechanism of the lower die have the advantage that during bending, a workpiece is in rolling contact with the lower die or the edge of the workpiece is in linear contact with the lower die, so that folded marks on the surface of the workpiece are prevented.
Description
Technical field
The present invention relates to a kind of bender lower die and auxiliary body thereof.
Technical background
Bending machine die is used to the instrument processing plate shaping, under the effect of bender pressure, is realized the processing of article profile by the change of institute's moulding material physical state.Blank is become the instrument of the product of given shape and size.
The different bending machine die of different blank parts is formed.Bending machine die is divided into upper die of bending machine and counterdie, for sheet metal forming and the mould be separated.The counterdie of shaping has V-shaped chamber, and separatory patrix has cutting edge.
In the manufacturing of a lot of product, need aluminium sheet bending, in original bender, bending can produce surface indentation, scratches, affects the outward appearance of product, even cause the processing performance of aluminium sheet to decline.
Summary of the invention
In order to overcome the above problem, the invention provides a kind of bender lower die and auxiliary body thereof, this counterdie and auxiliary body are made up of accurate roller, bending lower die, movable positioning plate, spring, lining, guide spiro rod and base.One of them V-type groove both sides tumbles in accurate roller, produces roll displacement when bending presses down; Second V-type groove two ends is furnished with movable positioning plate, allows workpiece contact with the V-type line of rabbet joint, utilizes spring to promote movable positioning plate and in bending lower die, moves up and down location, step-less adjustment sheet metal bending width, realize the isogonism Edge Bend of folding face without folding line.
For solving above technical problem, the invention provides following technical scheme: a kind of bender lower die and auxiliary body thereof, described counterdie has two V-shaped grooves, described auxiliary body is fixed on the both sides of the first V-shaped groove, this mechanism comprises movable positioning plate, spring, lining, guide spiro rod and base, described guide spiro rod vertically connects movable positioning plate, lining is provided with between guide spiro rod and movable positioning plate, guide spiro rod is through spring, under spring is pressed in movable positioning plate, be fixed on bottom guide spiro rod on base; Described auxiliary body also has roller, and described roller is arranged on the both sides, top of the second V-shaped groove, and the inclined-plane of the second V-shaped groove is tangent or crossing with this roller periphery; Described movable positioning plate is square plate, stretches out, in order to carry workpiece from the first V-shaped groove abutting end.
Further, the second V-shaped groove both sides of described counterdie have the groove placing roller, and roller can rotate around axle center in this groove, and the degree of depth of groove is greater than roller radius, is less than roller diameter.
Further, be provided with cant beam bottom described movable positioning plate and support, spring is positioned over below this cant beam.
Further, described guide spiro rod top has screw thread, and this screw thread place is provided with double nuts structure, is positioned on lining, plays the effect regulating activity orientation plate height.
This bender lower die that the present invention relates to and auxiliary body thereof, in Forging Process, workpiece and counterdie Structure deformation or workpiece edge and counterdie linear contact lay, surface of the work does not have folding line.

Detailed description of the invention
As shown in Figure 1-2, counterdie has two V-shaped grooves, auxiliary body is fixed on the both sides of the first V-shaped groove 6, this mechanism comprises movable positioning plate 5, spring 7, lining 4, guide spiro rod 3 and base 9, described guide spiro rod 3 vertically connects movable positioning plate 5, is provided with lining 4 between guide spiro rod 3 and movable positioning plate 5, and guide spiro rod 3 is through spring, spring 7 is pressed in movable positioning plate 5 times, is fixed on bottom guide spiro rod 3 on base 9.
Auxiliary body also has roller 1, and described roller 1 is arranged on the both sides, top of the second V-shaped groove 8, and the inclined-plane of the second V-shaped groove 8 is tangent or crossing with this roller 1 periphery.
Second V-shaped groove 8 both sides of counterdie 2 have the groove placing roller 1, and roller 1 can rotate around axle center in this groove, and the degree of depth of groove is greater than roller radius, is less than roller diameter.
Movable positioning plate 5 is square plate, stretch out from the first V-shaped groove 6 abutting end, in order to carry workpiece 10, this kind of bearing mode, form bilateral cantilever design, therefore, should support class formation be set bottom movable positioning plate, as cant beam or support floor etc., be conducive to the service life of the stable and movable positioning plate in the course of work.
Guide spiro rod 3 top has screw thread, and this screw thread place is provided with double nuts structure, is positioned on lining 4, plays the effect regulating movable positioning plate 5 height.Double nuts structure play strengthened thread connect effect, with spring free screen resilience after pressing down excessive and cause thread off.
The base 9 of this mechanism should have certain thickness according to actual conditions, or makes step and just can reach stable effect to the fixation of guide spiro rod.Base 9 and counterdie are threaded connection, and be threaded and can facilitate installation and removal, relative to counterdie, this auxiliary body belongs to consumable accessory, and thread connecting mode can bring convenience the beneficial effect of replacing.
As shown in Figure 2, the guide spiro rod 3 of mechanism is the screw rod of bottom with nut, and this guide spiro rod 3 passes from base bottom, connects rear use double nut and fixes, be conducive to the stable of this mechanism and ensure movable positioning plate vertical motion, ensureing the precision of institute's processing work 10.
