Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core tooling shaping, in particular to a magnetic core shaping tooling. Background Art

[0002] In the prior art, the magnetic core needs to be clamped and fixed before the annealing heat treatment process is performed. When the existing tooling clamps are used to clamp the short-bandwidth magnetic core with a width of less than 15 mm, the end faces may be unevenly pressed.

[0003] At present, in order to deal with the above situation: either more positioning components are used to further position the magnetic core, but this will make the disassembly and assembly process complicated, which is not conducive to improving production efficiency; or specific small-sized tooling is used for clamping, but such small-sized tooling is easily deformed and damaged after heat treatment or repeated use and cannot be used multiple times. Utility Model Content

[0006] Furthermore, the positioning plate is adapted to the shape of the abutment edge toward the side of the supporting base plate; when the distance adjustment mechanism is driven to adjust the distance between the clamped workpieces on both sides, the positioning plate abuts against the abutment edge to form a distance adjustment limit for adjusting the distance between the clamped workpieces on both sides.

[0007] Furthermore, the abutment edges on both sides extend straightly in the horizontal direction, and the lower part of the positioning plate is arranged in a straight plate shape. When the distance adjustment mechanism is driven to adjust the distance between the clamped workpieces on both sides, the end face of the positioning plate facing the supporting bottom plate is flush with the abutment edge and adapted.

[0009] Furthermore, the clamping plate forms a horizontal and flush clamping end surface toward one end of the supporting base plate, and when the distance adjustment mechanism is driven to adjust the distance between the clamped workpieces on both sides, the clamping end surfaces on both sides are arranged parallel to each other.

[0010] Furthermore, the positioning plate is provided with a through hole, and the distance adjustment mechanism includes a screw rod that is connected to the through holes on the positioning plates on both sides, nuts are screwed at both ends of the screw rod, and the positioning plates on both sides are assembled between the nuts on both sides.

[0022] In order to make the technical solution, purpose and advantages of the present invention more clearly understood, the present invention is further explained below in conjunction with the accompanying drawings and embodiments.

[0023] As attached Figure 1 to Figure 2 As shown, a magnetic core shaping tool of the utility model includes a supporting base plate 1, which is arranged in a rectangular shape, and a horizontal and flush supporting end surface 10 is formed on the upper side of the supporting base plate 1; the supporting base plate 1 has abutment edges 11 on both sides, and the abutment edges 11 on both sides extend straightly in the horizontal direction.

[0024] It also includes two groups of clamped workpieces 2, and the supporting base plate 1 is placed between the two clamped workpieces 2; the clamped workpieces 2 include a vertically extending positioning plate 21, the extension height of the positioning plate 21 is greater than the thickness of the supporting base plate 1, and the lower part of the positioning plate 21 is arranged in a straight plate shape, and the end surface of the positioning plate 21 facing one side of the supporting base plate 1 is flush with the abutment edge 11 and adapted; when the distance adjustment mechanism 3 is driven to adjust the distance between the clamped workpieces 2 on both sides, the lower part of the positioning plate 21 abuts against the abutment edge 11 to form a distance adjustment limit for adjusting the distance between the clamped workpieces 2 on both sides.

[0025] A clamping plate 22 is provided in the middle of the positioning plates 21 on both sides and extends in the horizontal direction toward one end of the supporting base plate 1; a distance adjustment mechanism 3 for adjusting the distance between the clamped workpieces 2 on both sides is connected between the two clamped workpieces 2; when the distance adjustment mechanism 3 is driven to adjust the distance between the clamped workpieces 2 on both sides, a horizontal clamping bottom surface 221 is provided on the lower side of the clamping plate 22, and the supporting end surface 10 is flush and matched with the clamping bottom surface 221; the supporting lower sides of the clamping plates 22 on both sides are in contact with the upper side of the supporting base plate 1.

[0026] The clamping plate 22 forms a horizontal clamping end surface 222 toward one end of the supporting base plate 1. When the distance adjustment mechanism 3 is driven to adjust the distance between the clamped workpieces 2 on both sides, the clamping end surfaces 222 on both sides are arranged parallel to each other.

[0027] The application principle is as follows:

[0028] Based on the arrangement of the distance adjustment mechanism 3 , the workpieces 2 clamped on both sides can perform clamping movement relative to the supporting base plate 1 .

[0029] Place a small-sized magnetic core 6 workpiece on the supporting end surface 10 on the upper side of the supporting base plate 1, and the clamping workpieces 2 on both sides with adjusted spacing can effectively position and clamp the magnetic core 6 workpiece in a small space with their extended clamping plates 22. At the same time, with the flush adaptation application of the supporting end surface 10 and the clamping bottom surface 221, it can ensure that the spacing adjustment of the clamping workpieces 2 on both sides is smooth and reliable during the application of the clamping force.

[0030] As a preferred embodiment, two groups of abutment plates 4 are arranged between the two clamped workpieces 2, and a clamping space for core shaping clamping is formed between the two clamping plates 22 and the two abutment plates 4. The lower clamping bottom surfaces 221 of the two clamping plates 22 and the lower end surfaces of the two abutment plates 4 are both supported and abutted against the supporting end surface 10 on the upper side of the supporting base plate 1.

[0031] The total length and width range of the clamped magnetic core 6 workpiece is expected, and a clamping plate 22 of a specific size is selected. The abutment plates 4 on both sides are positioned and joined to the two ends of the clamping plate 22 to adapt to the preset width setting of the clamped magnetic core 6 workpiece. The clamping plates 22 on both sides of the clamping spacing are adjusted to adapt to the preset length setting of the magnetic core 6 workpiece, so as to meet the stable clamping application of the magnetic core 6 workpiece.

[0032] As a preferred embodiment, a through hole is provided on the positioning plate 21, and the distance adjustment mechanism 3 includes a screw rod 31 which is connected to the through holes on the positioning plates 21 on both sides, and nuts 32 are screwed at both ends of the screw rod 31, and the positioning plates 21 on both sides are assembled between the nuts 32 on both sides.

[0033] In the positioning plate 21, two through holes are provided, and the two through holes are respectively provided on both sides of the clamping plate 22; two groups of screw rods 31 are provided, and the two groups of screw rods 31 are provided in parallel with each other, and the lower end of the through hole is horizontally flush with the lower end surface of the clamping plate 22 (clamping bottom surface 221) to ensure that the screw rod 31 is also connected to the upper supporting end surface 10 of the supporting base plate 1 to ensure the stability of the overall installation structure of the tooling.

[0034] The two groups of clamping plates 22 are arranged between the two groups of screws 31, and a clamping space 5 for clamping the magnetic core 6 is formed between the two groups of screws 31, the two groups of clamping plates 22 and the upper side of the supporting base plate 1. The screws 31 are provided with abutment plates 4 next to the clamping space 5, and the extension direction of the abutment plates 4 is parallel to the screws 31; two groups of abutment plates 4 are provided, and the distance between the two groups of abutment plates 4 is equal to the width of the clamping plates 22.

[0035] The pitch adjustment mechanism 3 is configured as a screw rod 31 and a nut 32 to provide a stable transmission adjustment application while reducing the processing cost of the tooling; the diameter of the screw rod 31 can be selected to be a steel screw rod 31 larger than 10 mm to ensure a reliable and stable structure.

[0036] Based on the preset processing size and the clamping positioning layout of the magnetic core 6 clamping range, the width dimension of the clamping plate 22 and the distance from the clamping plate 22 to the installation position of the screws 31 on both sides are determined, so as to select the abutment plate 4 of appropriate thickness for application; when performing the clamping application, the abutment plate 4 is placed between the clamping plate 22 and the screws 31 on both sides to form a positioning of the magnetic core 6 clamped in the width direction on the supporting base plate 1, and then the pressing and positioning of the clamped workpieces 2 on both sides along the length direction are adapted to meet the positioning and clamping application requirements of the magnetic core 6 placed in the clamping space 5.

[0037] The above is only a preferred implementation of the present invention. Those skilled in the art can still modify the embodiments without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as within the protection scope of the present invention.
