Abstract
The utility model discloses a lower mould of punching equipment is equipped with the unloading hole, the lower mould is including the last plate and the lower module that assemble together, goes up the plate and sets up the straight hole of profile modeling, and the straight hole of unloading is seted up to the lower module, and the aperture in the straight hole of unloading is greater than the internal diameter in the straight hole of profile modeling. The upper plate and the lower plate are independently processed and then assembled together after the processing is finished, so that a lower die and a blanking hole are formed. Compared with the prior art, the whole lower die is convenient to process. The waste materials punched by the punch from the product can smoothly fall into the blanking straight hole through the profiling straight hole and fall along the blanking straight hole, so that the blockage is not easy to occur.
Description
Technical Field
The utility model relates to a processing equipment of printer part, the punching equipment of concretely relates to printer plate.
Background
Punching equipment comprises an upper die and a lower die, wherein the upper die is provided with a punch, the lower die is provided with a blanking hole, a plate (such as a plate for assembling a printer) is positioned on the lower die, the punch punches corresponding parts of the plate to form required hole positions, and the punched waste is discharged along the blanking hole and leaves the lower die.
The lower die currently used by the applicant is shown in fig. 1 and 2, and the blanking hole 01 has the shape: the upper part is a straight hole 011, the depth of the straight hole is 2mm, the lower part is a taper hole 012, the taper is 1, and the depth of the taper hole is 23mm. In actual use, the punched waste material is easy to block in the blanking hole, and in serious cases, the punch head can be broken. Moreover, machining such blanking holes is quite difficult.
The blanking hole is processed by linear cutting, the diameter of a metal wire of the linear cutting is 0.2mm, and the width of a straight hole part of the blanking hole is 0.5-0.7mm. In the wire cutting, a straight hole with the depth of 25 is firstly cut on the lower die by the metal wire, the aperture of the straight hole is the aperture of the straight hole at the upper part of the blanking hole, and then the taper hole part of the blanking hole is processed by the metal wire. When the taper hole is processed, the metal wire needs to be inclined, and the inclined metal wire is easy to touch the hole wall of the straight hole at the upper part of the blanking hole, so that the blanking hole is difficult to process.
SUMMERY OF THE UTILITY MODEL
The utility model solves the technical problem that: how to simplify the processing of unloading hole, moreover, the waste material that is washed away is difficult to block up in the unloading hole.
In order to solve the technical problem, the utility model provides a following technical scheme: the lower die of the punching equipment is provided with a blanking hole, the lower die comprises an upper plate and a lower die which are assembled together, the upper plate is provided with a profiling straight hole, the lower die is provided with a blanking straight hole, and the aperture of the blanking straight hole is larger than the inner diameter of the profiling straight hole.
The upper plate and the lower plate are independently processed and then assembled together after the processing is finished, so that a lower die and a blanking hole are formed. Because the processing of the profiling straight hole on the upper plate is convenient, and the processing of the blanking straight hole on the lower plate is convenient, compared with the prior art, the processing of the whole lower die is convenient.
Because the aperture of the blanking straight hole is larger than the inner diameter of the profiling straight hole, the waste materials punched by the punch from the product can smoothly fall into the blanking straight hole through the profiling straight hole and fall along the blanking straight hole, and the blockage is not easy to occur.
Drawings
The invention will be further explained with reference to the drawings:
FIG. 1 is a top view of a prior art lower die;
FIG. 2 is a front view of a lower die of the prior art;
fig. 3 is a top view of the lower mold of the present invention;
fig. 4 is a front view of the lower mold of the present invention;
fig. 5 is a top view of the upper plate of the present invention;
fig. 6 is a front view of the upper plate of the present invention;
fig. 7 is a top view of the lower module of the present invention;
fig. 8 is a front view of the lower module of the present invention.
The symbols in the drawings illustrate that:
01. a blanking hole of a lower die in the prior art; 011. in the prior art, a straight hole of a lower die blanking hole; 012. in the prior art, a taper hole of a lower die blanking hole;
10. an upper plate; 11. profiling a straight hole;
20. a lower module; 21. and (5) blanking a straight hole.
Detailed Description
Referring to fig. 3 to 8, a lower die of the punching device is provided with a blanking hole, the lower die comprises an upper plate 10 and a lower die 20 which are assembled together, the upper plate is provided with a profiling straight hole 11, the lower die is provided with a blanking straight hole 21, and the aperture of the blanking straight hole is larger than the inner diameter of the profiling straight hole.
The number of the profiling straight holes 11 is a plurality of narrow and long holes, the shape of the holes is the same as that of holes needing to be punched on the product, and the number of the holes is also the same as that of the holes needing to be punched on the product.
The quantity of unloading straight hole 21 equals the quantity of profile modeling straight hole 11, and unloading straight hole 21 is the round hole, and the aperture of unloading straight hole is greater than the biggest internal diameter of profile modeling straight hole 11, and the junction department of unloading straight hole 21 and profile modeling straight hole 11 forms the step, and the waste material that is gone up from the product by the drift is pushed to the step department by the drift, and the waste material can be followed unloading straight hole 21 and fall off the lower mould once.
Threaded holes are formed in the middle positions of the upper plate 10 and the lower module 20, and the upper plate 10 and the lower module 20 are connected through threaded connecting pieces.
Alternatively, the thickness of the upper plate 10 is 5mm, the thickness of the lower plate 20 is 20mm, and the diameter of the blanking straight hole 21 is 2.5mm.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, changes may be made in the detailed description and the application scope according to the idea of the present invention, and the description should not be construed as limiting the invention.
