Abstract
A die jacket device with a punch fast to replace comprises a locating pin, a T-shaped dowel bar, the replaceable punch and an original punch. The locating pin is in interference fit with the original punch. The original punch is sleeved with the replaceable punch in an interference fit mode. The replaceable punch abuts against the locating pin. The head of the T-shaped dowel bar is connected with a screw hole of the replaceable punch through threads. A circumferential groove is formed in the cylindrical surface of the original punch, the central plane of the circumferential groove coincides with the central line of the screw hole, and the width of the circumferential groove is larger than the diameter of the T-shaped dowel bar.
Description
Technical field
The mould holder covering device that the present invention relates to a kind of fast changeable drift, belongs to diel field, is specially adapted to stamping procedure complexity and needs the manually hot stamping device of replacing drift.
Background technology
Punch forming is a kind of common machining process, and its depended on pressure machine and mould apply external force to section bars such as sheet material, band, tubing, make it to produce plastic deformation, thereby obtains the workpiece (stamping parts) of required form and size.Development along with moulding process, mould industry also develops rapidly, the hole flanging moulding process that pressure vessel head place takes over of take is example, in mould, there are the punch structures such as tapered punch, spherical drift, cylindrical punch, different structure form drift forming effect is different, and much technique needs the successively punching press of drift of different structure form; Just there is problem that plunger chip die is changed in this, current stamping parts manufactory often completes a hole flanging and all will first use original mould punching press, pulls down original mould afterwards from stamping machine, changes follow-up mould and proceeds punching press; While carrying out next time hole flanging, again follow-up mould is unloaded, load onto original mould, constantly repeat, operation is loaded down with trivial details; How to reduce die change frequency, improve die change efficiency, very large on punch forming quality and production efficiency impact, especially to adopting the producer of traditional non-Full-automatic punching machine punching press, in forming process, how the problem of quick-replaceable drift is particularly outstanding.
Summary of the invention
The present invention will overcome the above-mentioned shortcoming of prior art, provides that a kind of structure is relatively simple, design and manufacturing cost is relatively low, the mould holder covering device of fast changeable drift.
Technical scheme of the present invention is: the mould holder covering device of fast changeable drift, it is characterized in that: comprise alignment pin, T shape transmission rod, replaceable drift and original drift, described alignment pin interference fit is on original drift, described replaceable drift is enclosed within on original drift in the mode of matched in clearance, and described replaceable drift and alignment pin are conflicted; The head of described T shape transmission rod connects with the screw of replaceable drift with screw thread, on the cylinder of described original drift, be processed with circumferential recess, the median plane of described circumferential recess overlaps with described center line of bolt hole, and described circumferential recess width is greater than the diameter of described T shape transmission rod.
Preferably, described alignment pin number n1 >=1, and be circumferentially uniformly distributed along original drift.
Preferably, described T shape transmission rod number n2 >=3, and be circumferentially uniformly distributed along replaceable drift.
Preferably, described replaceable drift can be cylindrical punch, spherical drift.
Preferably, described original drift can be parabola shaped drift, spherical drift, tapered punch.
Preferably, described T shape transmission rod tail end is processed into T shape, or cross, L shaped.
The number of described alignment pin is determined according to the geomery of original drift and replaceable drift, and alignment pin is used for locating replaceable drift position, so that the circumferential recess on the original drift of T shape transmission rod rapid alignment; Described T shape transmission rod one end is processed with screw thread, and while preventing from dismantling replaceable drift, T shape transmission rod drops; The transmission rod other end is processed into T shape, is convenient to load onto the prolongation arm of force, loads and unloads replaceable drift; The stamping press size that the circumferential recess degree of depth is born according to T shape transmission rod is determined.
Advantage of the present invention is: mould holder covering device is simple in structure, easy to use, design and low cost of manufacture, fast changeable drift, significantly improving production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is different punch structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
1. replaceable drifts in Fig. 1,2. original drift, 3. alignment pin, 4.T shape transmission rod.11. cylindrical punch in Fig. 2,12 spherical drifts, 13 tapered punch.
The mould holder covering device of fast changeable drift of the present invention, it is characterized in that: comprise alignment pin 3, T shape transmission rod 4, replaceable drift 1 and original drift 2, described alignment pin 3 interference fit are on original drift 2, described replaceable drift 1 is enclosed within on original drift 2 in the mode of matched in clearance, and described replaceable drift 1 is conflicted with alignment pin 3; The head of described T shape transmission rod 4 connects with the screw of replaceable drift 1 with screw thread, on the cylinder of described original drift 2, be processed with circumferential recess, the median plane of described circumferential recess overlaps with described center line of bolt hole, and described circumferential recess width is greater than the diameter of described T shape transmission rod 4.
Preferably, described alignment pin 3 number n1 >=1, and be circumferentially uniformly distributed along original drift 2.
Preferably, described T shape transmission rod 4 number n2 >=3, and be circumferentially uniformly distributed along replaceable drift 1.
Preferably, described replaceable drift 1 can be cylindrical punch, spherical drift.
Preferably, described original drift 2 can be parabola shaped drift, spherical drift, tapered punch.
Preferably, described T shape transmission rod 4 tail ends are processed into T shape, or cross, L shaped.
The described T shape transmission rod other end is processed into T shape, is convenient to load onto the prolongation arm of force, loads and unloads replaceable drift.
On original drift, circumferentially depth of groove is determined as calculated according to the size of T shape stamping press that transmission rod bears.
The mould holder covering device of described fast changeable drift, during use, replaceable drift is linked together and is installed on stamping machine by T shape transmission rod and original drift, first stamping procedure is used replaceable drift punching press, after first stamping procedure completes, the T shape transmission rod of backing off, takes off replaceable drift, can directly carry out second stamping procedure, wish continues punching press, only need be loaded on replaceable drift and continue processing, the operation of having removed the original drift of dismounting from.
Content described in this description embodiment is only enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also and in those skilled in the art, according to the present invention, conceive the equivalent technologies means that can expect.
