Abstract

The invention relates to a clamping fixture for a forged piece. The clamping fixture is characterized by comprising a lower fixture body. An upper fixture body is supported above the lower fixture body by springs on two sides. A positioning nick for arranging the forged piece is reserved on the lower fixture body. The top of the lower fixture body is provided with clamping teeth for clamping the forged piece. The clamping teeth are positioned below the positioning nick. The positioning nick of the upper fixture body is used for positioning, the clamping teeth of the lower fixture body are stresses for clamping, and simultaneously, the clamping teeth can always clamp the forged piece by utilizing the springs, so the clamping fixture can overcome the defect of inconsistent shapes of the forged pieces, ensure positioning accuracy and realize firm clamping.

Description

A kind of forging clamp tool
Technical field
The present invention relates to a kind of tool that clamps that is used for forging processing.
Background technology
Regular meeting runs into the processing of forging in machining; Because the characteristic of forging and the restriction of workpiece shape; Utilize die cavity tool as shown in Figure 1 to process generally speaking, this tool comprises tool body 1, on tool body 1, is formed with the die cavity 2 that adapts with forging shape to be processed.When clamping, adopt two covers tool as shown in Figure 1, forging is clamped from both sides.Because in process, the friction between forging and the die cavity 2 makes die cavity 2 wearing and tearing, add forging itself expand with heat and contract with cold, make clamp after forging can produce displacement, reduced the precision of processing.
Summary of the invention
The purpose of this invention is to provide a kind of tool that clamps that can fit tightly between forging and the tool that makes.
In order to achieve the above object; Technical scheme of the present invention has provided a kind of tool that clamps of forging; It is characterized in that: comprise down tool body, last tool body is supported on down the top of tool body through the spring of both sides, is descending on the tool body having in order to put into the locating notch of forging; Have in order to clamp the clamping tooth of forging at the top of following tool body, clamp the below that tooth is positioned at locating notch.
Preferably, shown in down have locating slot on the tool body, on last tool body, be provided with in order to insert the locating piece of this locating slot.
The present invention utilizes the locating notch location of tool body; Utilize the stressed clamping of clamping tooth of tool body down; Utilize spring to make simultaneously to clamp tooth to clamp forging all the time, thus the present invention can to overcome the forging shape inconsistent, guarantee positioning accuracy and can firm must the clamping.
Description of drawings
Fig. 1 is original tool sketch map;
Fig. 2 clamps the tool sketch map for a kind of forging provided by the invention.
The specific embodiment
For making the present invention more obviously understandable, now with preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 2; A kind of forging provided by the invention clamp tool; Comprise down tool body 3, last tool body 4 is supported on down the top of tool body 3 through the spring 5 of both sides, is descending on the tool body 3 having the locating notch 6 in order to put into forging; Have in order to clamp the clamping tooth 7 of forging at the top of following tool body 3, clamp the below that tooth 7 is positioned at locating notch 6.
In order can accurately to locate between the tool body up and down,, on last tool body 4, be provided with locating piece 9 in order to insert this locating slot 8 having locating slot 8 on the tool body 3 down.
During work, adopt two covers tool provided by the invention, forging is clamped from both sides; 6 pairs of forging of locating notch position, and through clamping tooth 7 forging are clamped, in process; If situation such as run into that forging expands with heat and contract with cold can be adjusted through spring 5 automatically, make clamping force constant.
