Description
Technical field
The utility model relates to a kind of bender lower die and auxiliary body thereof.
Technical background
Bending machine die is the instrument of processing plate shaping, under the effect of bender pressure, realizes 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.Different blank parts will consist of with different bending machine dies.Bending machine die is divided into upper die of bending machine and counterdie, is used for sheet metal forming and the mould that separates.The counterdie of shaping usefulness has the V-shaped chamber, and separatory patrix has cutting edge.
In the manufacturing of a lot of products, need to be to the aluminium sheet bending, in original bender, the bending meeting produces surface indentation, scratches, and affects the outward appearance of product, even causes the processing performance of aluminium sheet to descend.
The utility model content
In order to overcome the above problem, the utility model provides a kind of bender lower die and auxiliary body thereof, and this counterdie and auxiliary body are comprised 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 move up and down the location in bending lower die, and step-less adjustment sheet material bending width realizes that the folding face is without the isogonism Edge Bend of folding line.
For solving above technical problem, the utility model provides following technical scheme: a kind of bender lower die and auxiliary body thereof, described counterdie has two-sided at least V-shaped groove, described 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, described guide spiro rod vertically connects movable positioning plate, be provided with lining between guide spiro rod and the movable positioning plate, 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, described auxiliary body also has roller, and described 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 described 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, described movable positioning plate is square plate, stretches out with the V-shaped groove abutting end, in order to carry workpiece.
Further, described movable positioning plate bottom is provided with cant beam and supports, and spring is placed 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 the lining, plays the effect of regulating the activity orientation plate height.
This bender lower die and auxiliary body thereof that the utility model relates to, in the Forging Process, workpiece contacts with the counterdie rolling or workpiece limit section contacts with lower loft, and surface of the work does not have folding line.
Description of drawings
Fig. 1 is the utility model bender lower die 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-the first V-shaped groove; The 7-spring; 8-the second V-shaped groove; The 9-base; The 10-workpiece.
The specific embodiment
Shown in Fig. 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, the described 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 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 and this roller 1 periphery are tangent or crossing.
The 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.
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 is threaded connection with counterdie, 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 be the bottom with the screw rod of nut, 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 guarantee the movable positioning plate vertical motion, guarantee the precision of institute's processing work 10.
