Abstract
The utility model discloses a plate-bending tool for the substantial non-cutting machining of a metal plate. The utility model aims to provide a plate-bending tool with simple structure, low fabrication cost, high plate-bending efficiency, and good quality. The technical proposal of the utility model is that the plate-bending tool comprises an upper die and a lower die, wherein the top surface of the lower die is formed by two inter-crossed inclined planes, with an included angle therebetween being less than or equal to the bend angle of a piece to be bended; the intersection of the inclined planes is an arc plane and engaged with the arc surface of the piece to be bended; a positioning supporter is provided at the right side of the lower die; a pin is provided on the inclined plane of the supporter and has a diameter less than the aperture of the piece to be bended; a supporter is provided at the left side of the lower die; a first roller is equipped on a shaft on the top of the supporter, and a second roller is provided on the upper die above the lower die and arced to engage with the transition arc of the piece to be bended. The utility model is used to bend plate-shaped work pieces.
Description
Technical field:
What the utility model related to a kind of metallic plate does not have machining, particularly a kind of bent plate frock substantially.
Background technology:
The crane industry has single-piece or several the plates that curved shape is arranged often, if adopt special-purpose squeezer moulding very uneconomical, if adopt manual bending, labour intensity is big, and efficient is low and be not easy to ensure the quality of products, thereby needs a kind of easy plate-bending apparatus, its manufacturing cost is low, and the efficient height.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, the low and bent plate efficient height of cost of manufacture, the measured bent plate frock of matter.The technical solution of the utility model is, a kind of bent plate frock, comprise upper die and lower die, the upper surface that it is characterized in that counterdie is two crossing inclined-planes, angle≤quilt between this two inclined-plane is bent the angle of bend of part, in the intersection on inclined-plane is that a cambered surface matches with the cambered surface of being bent part, right side at counterdie is provided with positioning supports, on the inclined-plane of this support, be provided with the pin of a diameter less than the aperture of being bent part, left side at counterdie is provided with support, one roller is transferred on the axle of this support, top, is provided with a roller on the patrix above the counterdie, and its radian matches with the transition arc of being bent part.The two ends of the roller that a left side is supported are provided with locating ring, and the distance between two locating rings equals by the width of curved part.The step axle and the mould bases hole at the roller two ends on the patrix are rotatably assorted.The utility model has compared with the prior art that making simple in structure is easy, cost is low and bent plate efficient height and the measured advantage of matter.
Description of drawings:
Fig. 1 is a front view of the present utility model, and Fig. 2 is that the A of Fig. 1 is to partial schematic diagram.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, the flexibility of the bent plate part of an embodiment is 90 degree, and two holes are arranged on the part, its production process is, elder generation's blanking is also bored two holes on request onboard, bend at plate-bending apparatus of the present utility model then, this plate-bending apparatus has a base 1, counterdie 8 is fixed on the base, and the upper surface of counterdie is two crossing inclined-planes, is that arc surface matches with the transition arc of being bent part in its intersection, according to the material and the thickness of crooked part, the rebound deformation amount of part after bending (determining according to check) as 88 degree, has considered that the rebound deformation amount is 2 degree.Be respectively equipped with in the left and right sides of counterdie that the back supports 7, prelocalization supports 2, this two supports by in the slotted hole that is bolted to base two, can realize left and right the moving of supporting by mobile bolt.The inclined-plane that prelocalization is supported is provided with a pin that is obliquely installed 3, and its diameter is less than the hole on the part.The back is fixed one on supporting, and the roller 6 that two ends are provided with locating ring is transferred on the axle that supports the back, and a patrix 4 moving up and down is arranged above counterdie, and this patrix is a rotary round roller, and the diameter of roller matches with the transition arc that is bent part.
The method of operating of brake forming is, press earlier the plate 5 after plate is also holed under the part, after adjusting prelocalization and support the distance at pin and counterdie arc surface center and fix according to the required distance of part drawing hole and twisted plate, flat board is placed on the back and front supporting, pin is placed in the plate hole, start press, patrix descending (or counterdie is up), flat board and counterdie are fitted, promptly finish brake forming work, part is taken out.The live-rollers that the live-rollers of patrix and back are supported can make the friction in the BENDING PROCESS of plate reduce, and moulding is more smooth.
The utility model is by changing the counterdie and the patrix of different gradients and radian, the bent plate of flexible different knuckle radius circular arcs.
Claims (3)
1. bent plate frock, comprise upper die and lower die, the upper surface that it is characterized in that counterdie is two crossing inclined-planes, angle≤quilt between this two inclined-plane is bent the angle of bend of part, in the intersection on inclined-plane is that a cambered surface matches with the cambered surface of being bent part, right side at counterdie is provided with positioning supports, on the inclined-plane of this support, be provided with the pin of a diameter less than the aperture of being bent part, left side at counterdie is provided with support, one roller is transferred on the axle of this support, top, be provided with a roller on the patrix above the counterdie, its radian matches with the transition arc of being bent part.
