Abstract

The utility model belongs to the mold design technique especially relates to a work piece positioner. This work piece positioner includes first locating piece (1) and second locating piece (2), and it is planes to have five faces in six faces of two locating pieces, has partial arch in the middle of the remaining locating surface, and bellied both sides have two sections respectively and sink. The utility model discloses not only can solve the difficult problem in location, can eliminate the yawing force that the part brought of once bending moreover, can fix a position the accuracy, produce high -quality part, reach the peak use rate of material, improve production efficiency and product percent of pass.

Description

A kind of Working piece positioning device

Technical field

The invention belongs to Design of Dies technology, particularly relate to a kind of Working piece positioning device.

Background technology

In many Bending Mould designs, there are many part bending limits higher, and material thicker (generally more than 3mm), add that there is profile in the face of relative crimp, out of plumb, part location difficulty is there will be time shaping, because bending angle and profile have distortion, be provided with positioner exactly, also can locate inaccurate, even can misplace, there will be error in forming process, cause a large amount of the scrapping of part, particularly for imported material, cause great waste, affect forming parts quality and manufacturing time.

Summary of the invention

The purpose of this utility model is: the method for conciliating decision bit problem by applying this novel clamping and positioning fixture, solves single part difficulty location and locates inaccurate problem, being convenient to application and the operation of this class frock.

The technical solution of the utility model is: a kind of Working piece positioning device, comprises in the first locating piece 1 and the second locating piece 2, two locating pieces six faces and has five faces to be planes, and having part protruding in the middle of remaining locating surface, sink with two sections respectively in protruding both sides.

Two described locating pieces have three screwed holes be used for fixing and two pin holes.

The utility model has the advantages that: the utility model not only can separate the problem of decision bit difficulty, and the side force that bending part brings can be eliminated, and can accurate positioning, produce high-quality part, reach the peak use rate of material, enhance productivity and product percent of pass.

Wherein, 1-first locating piece, 2-second locating piece, 3-screw hole, 4-pin hole, 5-bending part.

Detailed description of the invention

Below the utility model is described in further details.

Please wherein see Fig. 2, Fig. 3 and Fig. 4 simultaneously, Fig. 2 is the Section View of utility model; Fig. 3 is front view of the present utility model; Fig. 4 is the application example view of the utility model on bender.Described a kind of Working piece positioning device comprises 2 locating pieces.Wherein, two locating pieces are symmetrical relations, and two locating pieces have five faces to be planes in six faces, the face of remaining locating element, and centre has part protruding, and protruding both sides, respectively with two sections of lower limits, its objective is minimizing and feature contacts face, reduce manufacture difficulty; Locating piece has three screwed holes and two pin holes, be used to accurately be fixed on its work top.Refer to Fig. 3, it is front view of the present utility model.

Designer can click step Design Orientation device:

The first step: according to concrete profile and the bending situation of part, determines to design the plane of symmetry;

Second step: design coupling part profile, considers accurate positioning, processes, puts part conveniently.

3rd step: according to what design, the frock of a procedure in the configuration design of the disjunctor part be connected as a single entity, punching goes out bending and connects part.

4th step: directly installing forming part on the bender with novel locating device.

Operating personnel directly use company's part that a procedure punching goes out, and locate on the positioning device, and bending and molding is just passable according to the order of sequence, solve original location difficulty, are forbidden, can not produce the problem of qualified products.

Claims

1. A workpiece positioning device is characterized in that this bending die comprises a first positioning block (1) and a second positioning block (2), and five faces are planes in the six faces of the two positioning blocks, and the remaining There is a partial protrusion in the middle of the positioning surface, and two sections of depression are respectively arranged on both sides of the protrusion.

2. A workpiece positioning device according to claim 1, wherein the two positioning blocks are provided with three threaded holes and two pin holes for fixing.
