Abstract

The invention provides a production method of an electric cooker hard magnet. The production method of the electric cooker hard magnet enables the production efficiency to be improved and the production cost to be reduced while the quality is ensured. The production method comprises the steps of arranging a receiving tank for receiving a magnetic powder material and stamping the magnetic power material in the receiving tank into a finished product by using a stamping head; the production method is characterized in that the stamping direction of the stamping head is parallel to the working face of the finished electric cooker hard magnet; the cross section of the receiving tank is in accordance with the cross section of the finished electric cooker hard magnet in shape, and the inner walls of the receiving tank are all plane structures. The working face of the finished electric cooker hard magnet is a plane structure which is closely fitted with the inner wall of the receiving tank and shaped the same as the inner wall of the receiving tank, and the thickness of the finished electric cooker hard magnet is equal to the space between the inner walls of two sides of the receiving tank, and therefore, both flat working face of the finished electric cooker hard magnet and qualified thickness of the finished electric cooker hard magnet are guaranteed and a subsequent grinding step is avoided, and consequently, the working efficiency is improved and the production cost is saved.

Description

A kind of production method of electric cooker hard magnetic body
Technical field
The invention belongs to household electrical appliances manufacturing technology field, specially refer to a kind of production method of electric cooker hard magnetic body.
Background technology
Electric cooker hard magnetic body is the sheet component being stamped to form by said magnetic powder material, and its upper and lower two working faces require very smooth, and the thickness of electric cooker hard magnetic body also must be very accurate, reliable to ensure subsequent installation contact.The production method of traditional electric cooker hard magnetic body is first to utilize pressing equipment that said magnetic powder material is struck out to sheet component, and its concrete impact style is to utilize drift to go out working face; And then two working faces up and down of electric cooker hard magnetic body are polished, make working face smooth, regulate the thickness of electric cooker hard magnetic body simultaneously, aforementioned production method needs two steps, and not only rhythm of production is slow, has also increased human cost and the equipment cost of enterprise.
Summary of the invention
The object of the invention is to propose a kind of production method of electric cooker hard magnetic body, in ensuring the quality of products, enhance productivity, reduce production costs.
The production method of electric cooker hard magnetic body of the present invention is as follows: arrange one for holding the storage tank of said magnetic powder material, then utilize drift that the said magnetic powder material in storage tank is washed into finished product, key is that the pressing direction of described drift is parallel to the working face of electric cooker hard magnetic body finished product; The cross section of described storage tank conforms to the cross sectional shape of electric cooker hard magnetic body finished product, and the inwall of storage tank is planar structure.
Said magnetic powder material in storage tank is under the punching press of drift, can compress gradually the inwall of storage tank, the electric cooker hard magnetic body finished product that final formation is inner consistent with storage tank, because the cross section of storage tank conforms to the cross sectional shape of electric cooker hard magnetic body finished product, and the pressing direction of drift is parallel to the working face of electric cooker hard magnetic body finished product, therefore can learn, the working face of electric cooker hard magnetic body finished product is and is closely attached on storage tank inwall and the planar structure identical with storage tank inner wall shape, and the thickness of electric cooker hard magnetic body finished product is the spacing between the inwall of storage tank both sides, the working face that has so just not only ensured electric cooker hard magnetic body finished product is smooth, the thickness that has also ensured electric cooker hard magnetic body finished product meets the requirements, without follow-up polishing step, thereby improve operating efficiency, save production cost.
Further, the bottom of described storage tank is provided with opening, and described opening part is provided with a material returned portion by driving mechanism pushing tow.Before punching press and in punching course, utilize driving mechanism material returned portion to be withstood on to the bottom of storage tank, make the part of material returned portion as storage tank bottom land; After punching press completes, utilize driving mechanism that material returned portion pushing tow is entered in storage tank, thereby electric cooker hard magnetic body finished product is released to storage tank, to be that punching press is next time ready.
The production method of electric cooker hard magnetic body of the present invention, without follow-up grinding step, can only utilize punching press can produce up-to-standard finished product, has improved production efficiency, has reduced production cost, has good practicality.
Brief description of the drawings
Fig. 1 is the principle schematic of the production method of electric cooker hard magnetic body of the present invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as effect and the operation principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
Embodiment 1:
As shown in Figure 1, the production method of the electric cooker hard magnetic body of the present embodiment is as follows: arrange one for holding the storage tank 1 of said magnetic powder material, then utilize drift 2 that the said magnetic powder material in storage tank 1 is washed into finished product, key is that the pressing direction of described drift 2 is parallel to the working face of electric cooker hard magnetic body finished product; The cross section of described storage tank 1 conforms to the cross sectional shape of electric cooker hard magnetic body finished product, and the inwall of storage tank 1 is planar structure; The bottom of storage tank 1 is provided with opening, and described opening part is provided with a material returned portion 4 by driving mechanism 3 pushing tows, and driving mechanism 3 can be cam, repeats no more herein.
Before punching press and in punching course, utilize driving mechanism 3 material returned portion 4 to be withstood on to the bottom of storage tank 1, make the part of material returned portion 3 as storage tank 1 bottom land.Said magnetic powder material in storage tank 1 is under the punching press of drift 2, can compress gradually the inwall of storage tank 1, the electric cooker hard magnetic body finished product that final formation is inner consistent with storage tank 1, after punching press completes, utilize driving mechanism 3 that material returned portion 4 pushing tows are entered in storage tank 1, thereby electric cooker hard magnetic body finished product is released to storage tank 1, to be that punching press is next time ready.
Because the cross section of storage tank 1 conforms to the cross sectional shape of electric cooker hard magnetic body finished product, and the pressing direction of drift 2 is parallel to the working face of electric cooker hard magnetic body finished product, therefore can learn, the working face of electric cooker hard magnetic body finished product is and is closely attached on storage tank 1 inwall and the planar structure identical with storage tank 1 inner wall shape, and the thickness of electric cooker hard magnetic body finished product is the spacing between storage tank 1 both sides inwall, the working face that has so just not only ensured electric cooker hard magnetic body finished product is smooth, the thickness that has also ensured electric cooker hard magnetic body finished product meets the requirements, without follow-up polishing step, thereby improve operating efficiency, save production cost.
