Abstract
The utility model discloses a punching die capable of preventing material from jumping. The punching die comprises an upper die, a lower die and a punch mounted on the upper die, wherein a plurality of die holes are formed in the lower die, the upper part of each die hole is a taper hole gradually narrowed from outside to inside, the lower part of each die hole is a cylindrical hole coaxially butt-jointed with the narrow part of the taper hole, the inner diameter of the cylindrical hole is more than that of the narrow part of the taper hole, and the outer diameter of the punch adapts to the inner diameter of the wide part of the taper hole. When the punch punches through a plate, wastes are clamped in the taper holes, and when the punch goes up, the wastes do not go up along with the punch, so that the wastes are prevented from jumping out, and the punching quality and production efficiency are improved; when the punch is further used for punching a new plate, the wastes in the taper holes drop to the cylindrical holes to discharge.
Description
Technical field
The utility model relates to punching die field, particularly a kind of bounce-proof punching die.
Background technology
Punching die is manufacturing fundamental technology equipment, because the technical merit of punching die is determining the quality of product to a great extent, and production efficiency. thereby the height of the production technology level of punching die, the important symbol of weighing an enterprise product level height become.Referring to shown in Fig. 1 to Fig. 3, existing punching die comprises patrix (not shown), is arranged on drift 10 and counterdie 20 on patrix, on counterdie 20, offer some nibs 21, and the top of nib 21 is cylindrical hole 21a, the external diameter of the internal diameter of cylindrical hole 21a and drift 10 adapts, the bottom of nib 21 is bellmouth 21b, and the narrow portion of bellmouth 21b is docked with cylindrical hole 21a.But there is following defect in existing punching die: when the plate 30 that needs processing is worn in drift 10 punchings, waste material 31 can tilt and enter in cylindrical hole 21a, and when drift 10 rises, waste material 31 can be gradient and follow drift 10 up to walk, waste material 31 is easily jumped out, affect drilling quality and production efficiency, increase production cost.
Utility model content
Technical problem to be solved in the utility model is for shortcomings and deficiencies of the prior art, provides a kind of bounce-proof punching die, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of bounce-proof punching die, comprise upper die and lower die and be arranged on the drift on described patrix, on described counterdie, offer some nibs, the top of described nib is the bellmouth that ecto-entad narrows down gradually, the bottom of described nib is the cylindrical hole being coaxial docking with bellmouth narrow portion, the internal diameter of described cylindrical hole is greater than the internal diameter of described bellmouth narrow portion, and the wide portion of the external diameter of described drift and bellmouth internal diameter adapts.
In a preferred embodiment of the present utility model, the material that described drift and described counterdie all arrange is DC53 mould steel, and its hardness is 60～62 °.
Owing to having adopted technical scheme as above, when drift rushes threading part, waste material can be stuck in bellmouth, and when drift rises, waste material can and then not rise, and prevents that waste material from jumping out, and has improved drilling quality and production efficiency; When drift rushes while wearing new plate again, the waste material in bellmouth can drop in cylindrical hole and discharge.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to shown in Fig. 4 to Fig. 6, a kind of bounce-proof punching die comprises patrix (not shown), counterdie 200 and is arranged on the drift 100 on patrix, on counterdie 200, offer some nibs 210, the some nibs 210 in the present embodiment form rectangular mold bore region.In order to increase, improve punching effect, drift 100 and counterdie 200 are DC53 mould steel, and its hardness is 60～62 °.DC53 is the novel cold work die steel that SKD11 is improved, and its technical specification is loaded in the G4404 of Japanese Industrial Standards (JIS).DC53 has overcome the weakness of SKD11 high tempering hardness and toughness deficiency, will replace SKD11 in general and precision die field comprehensively.DC53 heat treatment hardness, higher than SKD11, can reach 62-63HRC high rigidity after high temperature (520-530 ℃) tempering, and aspect intensity and wearability, DC53 surpasses SKD11.DC53 toughness is 2 times of SKD11, and the toughness of DC53 is comparatively outstanding in cold work die steel, with the instrument that DC53 manufactures, seldom occurs crackle and cracking, has greatly improved service life.Residual stress after line cutting processing is less has reduced residual stress through high tempering, and crackle and distortion after line cutting processing are inhibited.DC53 machinability and abrasiveness surpass SKD11, use DC53 can increase the tool die life-span and reduce manufacturing procedure.
The top of nib 210 is the bellmouth 210a that ecto-entad narrows down gradually, in order conveniently to block the work difficulty of waste material 310 and reduction drift 100, the bellmouth 211a of wide portion internal diameter is more bigger than bellmouth narrow portion 212a internal diameter, the bellmouth 211a of wide portion internal diameter in the present embodiment is than the large 0.04mm of bellmouth narrow portion 212a internal diameter, and the external diameter of drift 100 and the bellmouth 211a of wide portion internal diameter adapts.The bottom of nib 210 is the cylindrical hole 210b being coaxial docking with bellmouth narrow portion 212a, and the internal diameter of cylindrical hole 210b is greater than the internal diameter of bellmouth narrow portion 212a, facilitates waste material 310 to discharge from cylindrical hole 210b.
During work, plate 300 is fixed on the station of counterdie 200, when drift 100 rushes threading part 300, waste material 310 can be stuck in bellmouth 210a, and when drift 100 rises, waste material 310 can and then not rise, prevent that waste material 310 from jumping out, improved drilling quality and production efficiency; When drift 100 rushes while wearing new plate again, the waste material 310 in bellmouth 210a can drop in cylindrical hole 310b discharges.
The utility model is applicable to the perforation processing of liquid crystal TV set backboard or other plates, highly versatile.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
