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

Bender counterdie and auxiliary body thereof
Technical field
The present invention relates to a kind of bender counterdie and auxiliary body thereof.
Technical background
Bending machine die is the instrument that is used for processing plate shaping, under the effect of bender pressure, realizes the processing of article profile through the change of institute's moulding material physical state.Blank is become has the instrument of the product of given shape and size.Different blank parts will use different bending machine dies to constitute.Bending machine die is divided into the bender upper die and lower die, is used for sheet metal forming and the mould that separates.The counterdie of shaping usefulness has the v die cavity, and separatory patrix has cutting edge.
In the manufacturing of a lot of products, need be to the aluminium sheet bending, in original bender, the bending meeting produces surface indentation, scratches, and influences the outward appearance of product, even causes the processing performance of aluminium sheet to descend.
Summary of the invention
In order to overcome the above problem, the present invention provides a kind of bender counterdie and auxiliary body thereof, and this counterdie and auxiliary body are made up of accurate roller, bending counterdie, movable positioning plate, spring, lining, guide spiro rod and base.One of them V-type groove both sides tumbles in accurate roller, when bending presses down, produces roll displacement; Second V-type groove two ends is furnished with movable positioning plate, lets workpiece contact with the V-type line of rabbet joint, utilizes spring to promote movable positioning plate and in the bending counterdie, moves up and down the location, and step-less adjustment sheet material bending width realizes that the folding face does not have the isogonism Edge Bend of folding line.
For solving above technical problem; The present invention provides following technical scheme: a kind of bender counterdie and auxiliary body thereof, and said counterdie has two-sided at least V-shaped groove, and said auxiliary body is fixed on the both sides of a V-shaped groove; This mechanism comprises movable positioning plate, spring, lining, guide spiro rod and base; Said guide spiro rod vertically connects movable positioning plate, is provided with lining between guide spiro rod and the movable positioning plate, and guide spiro rod passes spring; Spring is pressed under the movable positioning plate, and the guide spiro rod bottom is fixed on the base.
Further, said auxiliary body also has roller, and said roller is arranged on the both sides, top of another V-shaped groove, and the inclined-plane of V-shaped groove and this roller periphery are tangent or crossing.
Further, these V-shaped groove both sides of said counterdie have the groove of placing this roller, and roller can rotate around the axle center in this groove, and the degree of depth of groove is greater than the roller radius, less than the roller diameter.
Further, said movable positioning plate is a square plate, stretches out with the V-shaped groove abutting end, in order to carry workpiece.
Further, said movable positioning plate bottom is provided with cant beam and supports, and spring is placed below this cant beam.
Further, said guide spiro rod top has screw thread, and this screw thread place is provided with double nuts structure, is positioned on the lining, plays the effect of regulating the activity orientation plate height.
This bender counterdie and the auxiliary body thereof that the present invention relates to, in the bending process, workpiece contacts with the counterdie rolling or workpiece limit portion contacts with following loft, and surface of the work does not have folding line.
Description of drawings
Fig. 1 is bender counterdie of the present invention and the overall structure figure of auxiliary body thereof;
Fig. 2 auxiliary body structure chart;
The 1-roller; The 2-counterdie; The 3-guide spiro rod; The 4-lining; The 5-movable positioning plate; 6-first V-shaped groove; The 7-spring; 8-second V-shaped groove; The 9-base; The 10-workpiece.
The specific embodiment
Shown in Fig. 1-2, counterdie has two V-shaped grooves, and auxiliary body is fixed on the both sides of first V-shaped groove 6; This mechanism comprises movable positioning plate 5, spring 7, lining 4, guide spiro rod 3 and base 9; The said guide spiro rod 3 vertical movable positioning plates 5 that connect are provided with lining 4 between guide spiro rod 3 and the movable positioning plate 5, and guide spiro rod 3 passes spring; Spring 7 is pressed in movable positioning plate 5 times, and guide spiro rod 3 bottoms are fixed on the base 9.
Auxiliary body also has roller 1, and said roller 1 is arranged on the both sides, top of second V-shaped groove 8, and the inclined-plane of second V-shaped groove 8 and this roller 1 periphery are tangent or crossing.
Second V-shaped groove, 8 both sides of counterdie 2 have the groove of placing roller 1, and roller 1 can rotate around the axle center in this groove, and the degree of depth of groove is greater than the roller radius, less than the roller diameter.
Movable positioning plate 5 is a square plate, stretches out with first V-shaped groove, 6 abutting ends, in order to carry workpiece 10; This kind bearing mode; Form the bilateral cantilever design, therefore, should the support class formation be set in the movable positioning plate bottom; Like cant beam or support floor etc., help the service life of the stable and movable positioning plate in the course of work.
Guide spiro rod 3 tops have screw thread, and this screw thread place is provided with double nuts structure, is positioned on the lining 4, play the effect of regulating movable positioning plate 5 height.Double nuts structure plays the effect that strengthened thread connects, with spring free in that to press down the back screen resilience excessive and cause threading off.
The base 9 of this mechanism should have certain thickness according to actual conditions, perhaps makes step and just can reach stable effect to the fixation of guide spiro rod.Base 9 and counterdie are through being threaded, and being threaded to make things convenient for installation and removal, and with respect 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 this mechanism has the screw rod of nut for the bottom, and this guide spiro rod 3 passes from the base bottom, connects the back and uses double nut to fix; Help the stable of this mechanism and guarantee the movable positioning plate vertical motion, guarantee the precision of institute's processing work 10.
This bender counterdie provided by the invention and auxiliary body thereof can with bender and the supporting use of hydraulic press, the bending aluminium sheet can be rolled over corner aluminium such as nonstandard, inequilateral angle aluminium, and do not have folding line, scuffing.Width in corner aluminium can realize that the location backer that the width of inequilateral angle aluminium can be used bender realizes through regulating the activity orientation plate height.
The specific embodiment of the present invention does not constitute the restriction to the application's scope; Within every spirit in the present invention design and the principle, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within protection scope of the present invention.
