Description
Technical field
The utility model relates to mold parts field, particularly relates to a kind of combination push rod on mould.
Background technology
Cold punching technology is a kind of cutting highly efficient in productivity, few or the advanced processing method without cutting, all has a lot of advantages in economy and technical elements.It is easy and simple to handle, is convenient to realize mechanization and automation, is suitable for the production of part more in enormous quantities, and its goods generally do not need to make further machining, and dimensional accuracy and interchangeability are also all relatively good.So it occupies very consequence in the industry such as aviation, automobile, tractor, electrical equipment and electrical, precision instrumentation.In the middle of punching production, diel is as the concrete executing means of Sheet Metal Forming Technology, and natural attention, in fact, the design level of punching die structure and the accuracy of manufacture are the keys ensureing stamped part quality.Push rod ejects waste material after being used for stamping-out from punch-die, existing push rod generally adopts general tool steel to make, its service life is short, if push rod adopts hardness and the high carbide alloy of intensity to make, then its service life is than general tool steel height decades of times, when the workpiece size that will process is larger, corresponding push rod size is also larger, make according to carbide alloy, then die cost is very high, it is the several times even decades of times of ordinary steel molding jig, and Making mold is difficult, processing cost is high, and if push rod damages and then whole push rod will be changed, cause waste.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of combination push rod.
The utility model is achieved through the following technical solutions:
A kind of combination push rod, comprise canned paragraph, active section, canned paragraph adopts 45 steel to make, and active section adopts hard alloy steel to make; The lower end of described active section is provided with lug boss, and described lug boss is arranged in the depressed part on canned paragraph top; The centre position of described canned paragraph offers through hole, and the upper end hole wall of described through hole is provided with internal thread, active section offers up big and down small ladder hole, and described active section is connected with canned paragraph by screw.
As optimal technical scheme of the present utility model, between described active section and canned paragraph, form cavity.
As optimal technical scheme of the present utility model, described screw is holding screw.
As optimal technical scheme of the present utility model, the axial line of described through hole and the axial line of ladder hole are on same straight line.
Compared with prior art, the beneficial effects of the utility model are: push rod fabricated structure of the present utility model, active section part adopt carbide alloy make, hardness and intensity high, long service life, canned paragraph part adopts 45 steel, easy to process, manufacturing cost reduces greatly, and active section and canned paragraph removably connect, change and repair conveniently, very practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-canned paragraph; 2-active section; 3-lug boss; 4-through hole; 5-ladder hole; 6-screw; 7-cavity.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described one combination push rod, comprise canned paragraph 1, active section 2, canned paragraph 1 adopts 45 steel to make, and active section 2 adopts hard alloy steel to make, and is preferably YG20; The lower end of described active section 2 is provided with lug boss 3, and described lug boss 2 is arranged in the depressed part on canned paragraph 1 top; The centre position of described canned paragraph 1 offers through hole 4, and through hole 4 can reduce stress and concentrate, and the upper end hole wall of described through hole 4 is provided with internal thread, active section 2 offers up big and down small ladder hole 5, and described active section 2 is connected with canned paragraph 1 by screw 6.
Cavity 7 is formed between described active section 2 and canned paragraph 1; Described screw 6 is holding screw; The axial line of described through hole 4 and the axial line of ladder hole 5, on same straight line, ensure installation accuracy.
In sum, push rod fabricated structure of the present utility model, active section part adopt carbide alloy make, hardness and intensity high, long service life, canned paragraph part adopts 45 steel, easy to process, manufacturing cost reduces greatly, and active section and canned paragraph removably connect, change and repair conveniently, very practical.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
