Description
Technical field:
The utility model relates to multistage cold former technical field, particularly multistage cold former cutting system.
Background technology:
Multistation cold-forging former is that a kind of production efficiency is high, and production range is comparatively large, is applicable to distortion complicated, integrates the forming machine of upsetting, extruding, trimming.As shown in Figure 1, the cutting system of prior art adopts spring reset structure, and it controls cutting knife main shaft by spring-compressed and completes blank action, but due to spring length service time one, cause cutting knife main shaft reseting precision not high, and in the process run, noise is large.
Utility model content:
For the defect existed in prior art, it is not high that the purpose of this utility model solves precision in prior art exactly, and in the large problem of operation noise.
The utility model solves the technical scheme that its technical problem adopts: a kind of cold headers cutting system, comprise cutter, Cutter apron and support, Cutter apron is connected with support, cutter is located on support by pitman shaft, can move up and down, it is characterized in that: described Cutter apron two ends are equipped with cylinder, side and the bottom of cylinder are provided with air admission hole, piston and piston push rod is provided with in cylinder, piston push rod one end is connected with piston, the other end is connected with pitman shaft, controls cutter and moves up and down, complete blank action by cylinder promotion pitman shaft.
The utility model beneficial effect: the utility model changes traditional spring reset structure, have employed air-cylinder type resetting structure, controls cutter by cylinder and completes blank action, have precision high, run the features such as noise is low.
Accompanying drawing illustrates:
Fig. 1 is the utility model structure chart
In figure: 1 cutter, 2 Cutter aprons, 3 supports, 4 pitman shafts, 21 cylinders, 22 air admission holes, 23 pistons, 24 piston push rods
Detailed description of the invention:
As shown in Figure 1, the utility model provides a kind of multistage cold former cutting system, comprise cutter (1), Cutter apron (2) and support (3), Cutter apron (2) is connected with support (3), cutter (1) is located on support (3) by pitman shaft (4), can move up and down, it is characterized in that: described Cutter apron (2) two ends are equipped with cylinder (21), the side of cylinder (21) and bottom are provided with air admission hole (22), piston (23) and piston push rod (24) is provided with in cylinder (21), piston push rod (24) one end is connected with piston (23), the other end is connected with pitman shaft (4).
The utility model in use, when side air admission hole (22) air inlet of cylinder (21), cylinder (21) chamber internal upper part pressure increase, piston (23) moves down, thus drives cutter (1) to move down; When bottom inflow hole (22) air inlet of cylinder (21), cylinder (21) chamber inner bottom part pressure increase, piston (23) moves up, thus drives cutter (1) to move up.The utility model is moved up and down by cylinder (21) inner carrier (23), thus promote pitman shaft (4) and control cutter (1) and move up and down, complete blank action, there is precision high, run the features such as noise is low.
