Description

Assembly block for sintering magnetic steel

Technical Field

The utility model relates to the technical field of sintering, in particular to an assembly block for sintering magnetic steel.

Background

During the sintering process of powder metallurgy products, particularly during liquid phase sintering, the control range of sintering temperature is extremely small due to different formulas of partial products, so that a part of bonding phase of the products seeps onto the surfaces of the products during liquid state sintering. And like the rectangular hole on the assembly block, when the assembly magnet steel is sintered, the seepage of the sintering phase can be accumulated in the right angle, so that the original right angle is changed into a large R angle due to the accumulation of the bonding phase, and the magnet steel cannot be assembled.

SUMMERY OF THE UTILITY MODEL

The utility model provides an assembly block for sintering magnetic steel, aiming at solving the technical defects, and the assembly block can enable the leaked sintering phase to enter the expansion slot in the sintering process, thereby avoiding the influence of the sintering phase on the assembly of the rectangular through hole on the magnetic steel.

The utility model discloses an assembly block for magnetic steel sintering, which comprises a body, wherein the body is of a block structure, one or more rectangular through holes for assembling magnetic steel are formed in the body, the through holes penetrate through the whole body, expansion grooves are formed in the body at the positions corresponding to four corners of the rectangular through holes, the expansion grooves penetrate through the whole body, and the top ends of the four corners of the rectangular through holes are positioned in the expansion grooves.

Above-mentioned scheme sets up the expansion groove at the top at four angles of rectangle through-hole, just expansion groove and rectangle through-hole intercommunication, and in the sintering process, can get into the expansion groove when the sintering is oozed mutually, and can distribute on the circumference lateral wall of expansion groove, and the angle of rectangle through-hole is located the central zone of expansion groove, so the sintering phase can not occupy the position of rectangle through-hole, so can realize the assembly to follow-up magnet steel, in order to promote the life of body. In addition, the expansion groove penetrates through the whole body, so that sintered phases in the expansion groove can be cleaned, the method is simple and convenient, and the side wall of the rectangular through hole cannot be damaged.

The horizontal cross-sectional shape of the expansion groove is as follows: the top end of the corresponding corner on the rectangular through hole is taken as the center of a circle, the length R is taken as the radius, and a fan shape of 270 degrees is formed outside the rectangular through hole. The design of the structure is convenient for processing the expansion groove, and the expansion groove is arc-shaped, so that the sintering phase in the expansion groove is more convenient to clean.

The length R is 5-10 mm. Length R should not be too big, and too big R can cause the integrality of rectangle through-hole relatively poor, can influence the quality of magnet steel sintering, and if length R undersize, then can cause the sintering phase to ooze and get into the extension groove and smooth and easy inadequately, lead to piling up in the right angle department of rectangle through-hole, influence normal use.

And two opposite side walls of the body are respectively provided with a positioning bulge, and the positioning bulges are used for limiting the position of the body. Set up the location arch on two relative lateral walls of body, can realize the fixing to the body in sintering process, and it is more convenient to fix, is difficult for rocking in the sintering process to promote the sintering quality.

The assembling block for sintering the magnetic steel, which is obtained by the utility model, can effectively solve the influence of sintering seeped in the sintering process on the rectangular through hole so as to improve the service performance and prolong the service life of the assembling block.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purpose of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Example 1:

as shown in fig. 1 and 2, the utility model discloses an assembly block for sintering magnetic steel, which comprises a body 1, wherein the body 1 is of a block structure, two rectangular through holes 2 for assembling the magnetic steel are formed in the body 1, the through holes penetrate through the whole body 1, expansion grooves 3 are formed in the body 1 at the positions corresponding to the four corners of the rectangular through holes 2, the expansion grooves 3 penetrate through the whole body 1, and the top ends of the four corners of the rectangular through holes 2 are positioned in the expansion grooves 3. In other embodiments, the number of the rectangular through holes 2 opened on the body 1 may be 1 or 3, or even more.

Set up expansion groove 3 at the top at four angles of rectangle through-hole 2, expansion groove 3 is located the outside of rectangle through-hole 2, just expansion groove 3 and rectangle through-hole 2 intercommunication, in the sintering process, can get into expansion groove 3 when the sintering is oozed mutually, and can distribute on the circumference lateral wall of expansion groove 3, and the angle of rectangle through-hole 2 is located the central zone of expansion groove 3, so the sintering phase can not occupy the position of rectangle through-hole 2, so can realize the assembly to follow-up magnet steel, in order to promote the life of body 1. In addition, because the expansion groove 3 also penetrates through the whole body 1, the sintering phase in the expansion groove 3 can be cleaned, the method is simple and convenient, and the side wall of the rectangular through hole 2 cannot be damaged.

The horizontal cross-sectional shape of the expansion groove 3 is as follows: the top end of the corresponding angle on the rectangular through hole 2 is taken as the center of a circle, the length R is taken as the radius, and a fan shape of 270 degrees is formed outside the rectangular through hole 2. The design of the expansion slot 3 with the fan-shaped horizontal section has the advantages that the expansion slot 3 is convenient to process, and the expansion slot 3 is arc-shaped, so that the sintered phase in the expansion slot 3 is more convenient to clean. The horizontal section is a plane perpendicular to the axial direction of the through hole.

The length R is 5-10mm, and any value of 5mm, 6mm, 7mm, 8mm, 9mm and 10mm can be selected, and non-integer values in the range can be selected. Length R should not be too big, and too big R can cause the integrality of rectangle through-hole 2 relatively poor, can influence the quality of magnet steel sintering, and if length R undersize, then can cause the sintering phase to ooze and get into expansion tank 3 not smooth enough, lead to piling up in the right angle department of rectangle through-hole 2, influence normal use. The above-mentioned too large length R means that the length R is larger than 10mm, and the too small length R means that the length R is smaller than 5 mm.
