Description
Technical field
The utility model belongs to technical field of mold, particularly relates to a kind of anti-upper device of jumping of the monolithic blanking die for the production of motor stator.
Background technology
Motor is a kind of equipment of mechanical energy that electric energy is converted to, it is to utilize stator winding to produce rotating excitation field and act on the closed aluminium frame of rotor mouse cage to form magnetoelectricity dynamic rotation moment of torsion, under the effect of stator winding rotating excitation field, in the closed aluminium frame of mouse cage, have electric current by and be subject to the effect in magnetic field that aluminium frame is rotated.Stator core generally by 0.35-0.5 millimeters thick surface have insulating barrier punching silicon-steel, be overrided to form, the circumference upper punch of silicon steel sheet has equally distributed groove, in order to embed stator winding, the centre punch of silicon steel sheet has circular hole, for the installation of stator.
At present, for the blanking die of motor stator monolithic stamping die, when the stamping-out, there is easily upper situation of jumping of product, after the method that prior art adopts is punch stamping-out, pause the regular hour, reset again subsequently, but exist like this production efficiency lower, the problem that production cost is higher; What also have employing is that a clamping mechanism is set in the inside of die, but in actual use, this clamping mechanism easily causes stamping-out product edge burr out more, and causing product quality relatively poor, yield rate is lower, and then causes production cost higher, and during assembling, burr easily hurts assembling workman, has potential safety hazard, and security is poor.
Utility model content
The utility model provides a kind of stamping-out product edge that makes more smooth for above problem, and production efficiency is higher, and yield rate is higher, and production cost anti-going up lower and the good monolithic blanking die of assembling security jumped device.
The utility model is to overcome the above problems technical scheme used to be: a kind of anti-upper device of jumping with the monolithic blanking die of following structure is provided, it comprises die block and die, described die is connected with die block, described die block upper surface is provided with fixed block, described fixed block lower surface is provided with the groove of a side opening, and the opening of groove is positioned at a side of the nearly die of fixed block, in described groove, slidably connect sliding-tongue, described sliding-tongue one end be positioned at cutting edge of die directly over, and the sliding-tongue other end is provided with the resetting-mechanism that sliding-tongue resets, between the side of nearly die one side of described sliding-tongue upper surface and sliding-tongue, it is chamfered transition, between described sliding-tongue and fixed block, be provided with journey stop gear.
Adopt after above structure, compared with prior art, the utility model is put jumping device owing to being provided with on die block, by sliding-tongue, be positioned at a upper jumping of bringing in limits product of cutting edge of die top, and be chamfered transition between the side of nearly die one side of sliding-tongue upper surface and sliding-tongue, in use, effect downslide tongue portion at material base is retracted in fixed block, under the effect on inclined-plane, during die undershoot, sliding-tongue is all retracted into fixed block, do not affect the normal stamping-out of punch, and after punch stamping-out during rollback, when the process sliding-tongue of the lower surface of punch, Rapid reset under the effect of the resetting-mechanism of sliding-tongue, thereby the product in die is played to spacing effect, to reach, prevent the object of jumping on product, in whole stamping-out back off procedure, punch does not need to pause, continuous production is better, cycle is shorter, production efficiency is also just higher, production cost also just decreases, and put, jump the upper surface that device is arranged on die block, therefore do not contact with the product in moulding or after moulding, also just can not cause product to occur the problem of burr, product quality is also just relatively better, yield rate is higher, and then reduces production cost, and during assembling, also just do not exist burr easily to hurt assembling workman's situation, security is better, moreover journey stop gear can prevent that the sliding-tongue situation that sliding-tongue ejects when resetting from occurring effectively, make the stability in use of sliding-tongue better, the work continuity of punch is better, and then guarantees production efficiency.Therefore the utlity model has and make stamping-out product edge more smooth, production efficiency is higher, and yield rate is higher, the lower and good feature of assembling security of production cost.
As improvement, described resetting-mechanism comprises elastic component, described elastic component is at sliding-tongue other end end face and groove between the sidewall away from die, and elastic component one end and sliding-tongue other end end face are fitted, and the elastic component other end and groove are away from the sidewall laminating of die; The resetting-mechanism structure of this structure is simpler, and parts are less, and stability in use is better, and cost is also lower.
As further improvement, the described sliding-tongue other end is provided with at least one open slot, described elastic component and open slot are one-to-one relationship, elastic component be positioned at open slot, and elastic component one end and the laminating of open slot bottom surface, the elastic component other end and groove be away from the sidewall laminating of die, and the length of described sliding-tongue one end in groove outside is less than sliding-tongue other end end face and groove away from the spacing between the sidewall of die; After open slot arranges, when elastic component is out of shape in open slot, under the restriction of open slot, there will not be crooked situation, and then prevent from occurring the situation that sliding-tongue stops after elastic component bending, not increasing under the prerequisite of parts, further improve the stability in use of resetting-mechanism.
As further improving, described open slot is two, and two open slots be arranged in parallel again; Two parallel corresponding two parallel elastic components of parallel open groove, make sliding-tongue stressed more even when retraction and reset, there will not be the situation of skew, can effectively prevent that situation about blocking from appearring in sliding-tongue, make the stability in use of resetting-mechanism better, cost is relatively low again simultaneously.
As further improving, described journey stop gear comprises the waist-shaped hole that sliding-tongue is provided with again, and the fixed block directly over described waist-shaped hole is provided with through hole, in described through hole, is provided with limited post, and the lower end of described limited post is arranged in waist-shaped hole; The journey stop gear of this structure, structure is simpler, and parts are less, and cost is lower, and stability in use is also better, and is also convenient to assembling and safeguards.
As further improving, described through hole is screwed hole, and described limited post is double-screw bolt, and the upper end of limited post screws in through hole, and the lower end of limited post is arranged in waist-shaped hole; The limited post of this structure and through hole, make the installation rear stability of limited post better, is not prone to the situation of rocking, and then guarantee also to make the stability in use of sliding-tongue better by the stability in use of journey stop gear simultaneously.
As preferably, described elastic component is spring, and the cost of spring is lower, is convenient to user's later maintenance.
