Abstract
The utility model discloses a kind of magneto rotor waste product cutting die, comprise the patrix, fixed head, backing plate and the upper bolster that are fixedly connected sequentially; And the counterdie be fixedly connected sequentially, fixed head, backing plate and die shoe, also comprise locating dowel, described locating dowel is fixedly connected with backing plate; Described upper die and lower die all have multiple and are strip structure, and the face that described upper die and lower die contact with waste product is provided with the stupefied of projection; Upper die and lower die quantity is identical with T-shaped number of teeth amount and all uniform ringwise around described locating dowel.The magneto rotor waste product cutting die operating efficiency of employing the utility model conceptual design is high and security is good.
Description
Technical field
The utility model relates to a kind of waste recovery mechanism, is specifically related to a kind of cutting die for magneto rotor waste recovery iron core.
Background technology
Magneto core is a requisite part in magneto.Permanent magnet rotates in the core which, and the primary coil on iron core induces electromotive force, generation current when contact breaker points closes, when contact breaker points throw open, suddenly cut off primary current time, secondary coil induces quite high electromotive force, makes spark plug sparking.
In magneto core process of manufacture, need to wrap up one deck plastics at the T-shaped tooth outer surface of all sides of lamination.But, often because the surface of core and lamination does not fit tightly, cause plastics can enter in the gap of core and lamination.To terminate when injection moulding and after being taken out by lamination, this lamination does not need to wrap up the part of plastics still has plastics to cover, and is waste product.If directly abandoned by waste product, not only waste raw material, and be unfavorable for environmental protection.
Conventional means of the prior art is for reclaim waste product manually: parts of plastics is removed with the rod tool of keen edge by manual operation, the partially recycled recycling of remaining lamination, is about to reclaimed lamination part and again processes in Mold for Plastics.So not only can improve raw material availability, again can be cost-saving.But reclaim waste product not only inefficiency manually, cost is high, and rod tool has sharp cutting edge, easily hurts sb.'s feelings, and is absolutely unsafe, and also increases the amount of labour of workman.
Manually do over again, efficiency is low again.Existing we design different moulds, correspondence excised by molded portion, withdraw from lamination and again utilize with punch press.Both ensured safety, cost declining, raises the efficiency again.
Utility model content
For the defect that above-mentioned prior art exists, technical problem to be solved in the utility model is to provide and a kind ofly reclaims the high and magneto rotor waste product cutting die of safety of iron core efficiency.
In order to solve the problems of the technologies described above, the utility model provides a kind of magneto rotor waste product cutting die, comprises the patrix, fixed head, backing plate and the upper bolster that are fixedly connected sequentially; And the counterdie be fixedly connected sequentially, fixed head, backing plate and die shoe, also comprise two locating dowels, described two locating dowels are fixedly connected with two backing plates respectively; Described upper die and lower die all have multiple and are strip structure, and the face that described upper die and lower die contact with waste product is provided with the stupefied of projection; Upper die and lower die quantity is identical with T-shaped number of teeth amount and all uniform ringwise around described locating dowel.
Further improvement as the utility model above-mentioned magneto rotor waste product cutting die: described fixed head is strip structure, its quantity is identical with patrix or counterdie quantity.The surface that fixed head contacts with patrix or counterdie has dovetail groove, and upper die and lower die surface is fixedly connected with the trapezoidal projection matched with dovetail groove; The notch of described dovetail groove is less than slot bottom width.
Further improvement as the utility model above-mentioned magneto rotor waste product cutting die: also comprise connecting bolt, the bottom land of described dovetail groove has two or more counterbore, and connecting bolt is fixedly connected with backing plate through described counterbore.
The magneto rotor waste product cutting die tool of said structure is adopted to have the following advantages:
(1) magneto core waste product is enclosed within the locating dowel that fixed head is fixedly connected with, magneto core waste product can be made to carry out quick position, save time; (2) manual rotation magneto core waste product, make the neutrality line of T-shaped tooth with after stupefied relative on counterdie, patrix moves down, and under the extruding of upper die and lower die, make the plastic layer quick separating on T-shaped tooth, waste recovery efficiency far is higher than the efficiency of manual recovery; (3) volume of upper die and lower die is little, lightweight, adopts baby press to install, energy-saving and emission-reduction, reduces production cost; (4) workman only needs controlled pressure machine control handle, largely avoided the probability of worker injuries, reduces the amount of labour of workman simultaneously; (5) when certain needs to change when patrix or counterdie, can dismantle separately and change, save mold use cost.
