Abstract
The invention provides a clamp for clamping forging blanks. The clamp comprises two clamping hands connected by a dowel in a crossed manner and chucks at the tops of the clamping hands, wherein the clamping hands are divided into three sections, namely hand gripping rods, intermediate rods and clamping rods, the intermediate rods are arranged in positions close to the clamping rods, the top ends of the clamping rods are detachably connected with the chucks, the dowel is arranged in the positions of the intermediate rods and connects the two clamping hands, and one ends of the hand gripping rods are wrapped with a heat insulating layer. The clamp has the advantages that the clamping of the blanks requires less force; due to the adoption of a detachable connecting mode, the chucks can be changed according to blanks in different shapes and sizes; the inner walls of the clamping plates are smooth, so that the blanks are prevented from deforming in the clamping process; and even if protective gloves are not put on, the hands cannot be scalded in the blank clamping process.
Description
Technical field
The invention belongs to forging and stamping field, especially relate to the fixture of a kind of gripping forging and stamping blank.
Background technology
In forging and stamping process, need fixture to adjust the putting position of blank, the different parts of blank is forged and pressed.And not of uniform size also determine of blank needs to change the blank that fixture carrys out gripping difformity size, the fixture of prior art can not realize the function of replaceable chuck.Blank makes to have plastic after high-temperature process, when fixture picks up blank time, if the contact surface of fixture and blank is unsmooth, can cause blank deformation, affect the mould molding in later stage.General blank is steel body, very heavy, can require great effort very much when gripping, and is high temperature, needs workman to bring protective gloves.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of laborsaving, heat insulation, replaceable chuck, keeps the fixture of blank shape.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of fixture of gripping forging and stamping blank, comprise two chucks with the cross-coupled tong of pin, tong top, described tong is divided into three sections, is hand-held pole, intermediate bar and clamping bar, and intermediate bar is located at the position near clamping bar, the top of clamping bar removably connects chuck, the position of intermediate bar is located at by pin, and connects two tongs, and one end of hand-held pole is enclosed with thermal insulation layer.
Further, be bolted between described chuck and clamping bar; Or described chuck is the clamping plate with hollow sleeve, and sleeve pipe is inserted in clamping bar and is fastened by bolts.These two kinds of dismountable connected modes.
Further, described chuck is both sides 90 ° of bending clamping plate in the same way; Or described chuck is the clamping plate of middle part outwardly convex, clamping plate both sides and reverse 90 ° of raised position bend.These two kinds of chucks.
Further, described hand-held pole is parallel with clamping bar, and in being not less than 150 ° of angles between intermediate bar and hand-held pole, intermediate bar is located at tong 1/5 place.The moment increasing hand-held pole can reach labour-saving effect, more easily picks up blank.
Further, described clamping plate interior walls be smooth.Can ensure that the contact surface of blank and chuck is level and smooth, avoid blank to be out of shape in gripping process.
The advantage that the present invention has and good effect are:
1. increase the moment of hand-held pole, more laborsaving when making gripping blank;
2. adopt the mode that removably connects, chuck can be changed for the blank of difformity size;
3. clamping plate interior walls be smooth, avoids blank to be out of shape in gripping process;
4. two kinds of chucks are provided, the blank of different length can be adapted to;
5. hand-held pole parcel thermal insulation layer, just can avoid without the need to being with protective gloves scalding in gripping blank process.
