Description

Technical Field

[0001] The utility model relates to the technical field of alloy resistor production, in particular to a solidification and sintering auxiliary jig for alloy resistor production. Background Art

[0002] Alloy resistors refer to resistors that use alloys as current media. They have the characteristics of low resistance, high precision, low temperature coefficient, resistance to impact current, and high power. They are widely used in precision instruments, military products, aerospace electronics, new energy photovoltaic products, automobiles, etc.

[0003] The production process of alloy resistors is generally divided into the following steps: sheet stamping, laser resistor trimming, epoxy molding, plastic molding channel cutting, surface sandblasting, code printing, sintering and curing, and pelletizing. During the sintering and curing process, the slurry is printed on the surface of the resistor on the sheet and sintered and cured to achieve good performance.

[0004] In the existing technology, a sintering furnace is generally used for this work. The traditional practice is to stack multiple sheets up and down and place them together in a sintering furnace for batch work. However, the permeability of the sheets is reduced after they are stacked, which affects the gas exchange during the sintering process, increases the difficulty of sintering, and may cause the sintering process to be unstable, thereby affecting the quality and performance of the product. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a solidification and sintering auxiliary jig for alloy resistor production, which can ensure the quality of solidification and sintering.

[0006] To achieve the above purpose, the present invention adopts the following contents:

[0007] The utility model provides a curing and sintering auxiliary jig for alloy resistor production, which includes a pair of parallel and spaced fixed side plates, a plurality of connecting horizontal plates are arranged in an array between the two fixed side plates, and a plurality of mounting vertical plates are arranged in an array on the top of the plurality of connecting horizontal plates. The extension direction of the mounting vertical plates is consistent with the extension direction of the fixed side plates, and the top surface of the mounting vertical plates is recessed inward to form a plurality of vertical slots in the array, and the vertical slots on adjacent mounting vertical plates are aligned side by side.

[0008] According to the present invention, a solidification and sintering auxiliary jig for alloy resistor production is provided. The top and sides of the vertical slot are formed with outwardly curved guide portions. These curved guide portions reduce the difficulty of entering the vertical slot from top to bottom, allowing the blank to be quickly and easily inserted vertically into the slot.

[0009] According to the present invention, a solidification and sintering auxiliary jig for alloy resistor production is provided. The top surface of the connecting horizontal plate is recessed inward to form a plurality of spaced-apart mounting slots. The mounting slots on adjacent connecting horizontal plates are aligned side by side, and the width of the mounting slots matches the thickness of the mounting vertical plates. This allows for a removable connection between the mounting slots and the mounting vertical plates, facilitating assembly and replacement of different mounting vertical plates.

[0010] Furthermore, the two side ends of the mounting risers are flush with the outer walls of the two outermost connecting transverse plates, and baffles are provided on the outside of the two outermost connecting transverse plates. Thus, when the mounting risers are inserted into the corresponding mounting slots on the connecting transverse plates, there is no need to further adjust the positions of the two sides of the mounting risers. The baffles on both sides can easily ensure that the adjacent mounting risers are flush, thereby ensuring that the vertical slots on the adjacent mounting risers are aligned side by side.

[0011] According to the present invention, a solidification and sintering auxiliary jig for alloy resistor production is provided. The top ends of the fixed side plates are bent outward to form inclined plates. The inclined plates on both sides are mainly used to facilitate the operator to hold and put down the jig from both sides, which is equivalent to an angled handle.

[0012] According to the present invention, a solidification and sintering auxiliary jig for alloy resistor production is provided, wherein the bottom end of the fixed side plate is located on a plane coplanar with the bottom end of the connecting horizontal plate. This ensures the stability of the jig placement, ensuring safe use and smooth operation of the jig.

[0013] Compared with the existing technology, the present invention has the following technical effects: the present invention has a simple structure and a reasonable design; the sheet can be inserted horizontally into a row of vertical slots on adjacent mounting vertical plates in a vertical posture, thereby achieving separation of multiple sheets and avoiding overlapping of sheets, thereby ensuring the uniformity of the sintering process of these sheets in the sintering furnace and ultimately achieving good product quality.

[0019] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive and should not limit the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] See also Figure 1 and Figure 2 As shown. The present invention provides a solidification and sintering auxiliary jig for alloy resistor production, comprising a pair of parallel, spaced fixed side panels 1. Five connecting horizontal panels 2 are arranged in an array between the two fixed side panels 1. Five mounting vertical panels 3 are arranged in an array atop the five connecting horizontal panels 2. The mounting vertical panels 3 extend in the same direction as the fixed side panels 1. The top surfaces of the mounting vertical panels 3 are recessed inward to form a plurality of vertical slots 31 in an array. The vertical slots 31 on adjacent mounting vertical panels 3 are aligned side by side. The fixed side panels, connecting horizontal panels, and mounting vertical panels are all integrally formed from steel.

[0022] The use of this fixture is particularly simple, such as Figure 3 As shown, it is only necessary to insert each sheet 5 in a vertical position into a row of vertical slots 31 on the adjacent mounting vertical plates 3, and maintain a certain distance between adjacent sheets 5. Then the fixture is placed in a sintering furnace for sintering and curing. It is simple, practical and low-cost.

[0023] The top two sides of the vertical slot 31 are curved guide portions 311 that bend outward. The curved guide portions on both sides of the top of the vertical slot reduce the difficulty of the sheet entering the vertical slot from top to bottom, and the sheet can be quickly and easily inserted vertically into the vertical slot to prevent mis-insertion.

[0024] The top surface of the connecting horizontal plate 2 is recessed inward to form a spaced array of mounting slots 21. The mounting slots 21 on adjacent connecting horizontal plates 2 are aligned side by side, and the width of the mounting slots 21 matches the thickness of the mounting vertical plates 3. This allows for a removable connection between the mounting vertical plates, facilitated by the clearance fit between the mounting slots and the mounting vertical plates, and facilitates assembly and replacement of different mounting vertical plates. Different thicknesses of the plates necessitate different widths of the vertical slots on the mounting vertical plates, allowing removal and replacement of the mounting vertical plates to accommodate the type of plate.

[0025] Furthermore, the two side ends of the mounting risers 3 are flush with the outer walls of the two outermost connecting transverse plates 2. In other words, the length of the mounting risers is equal to the maximum distance between the five connecting transverse plates. Furthermore, baffles 4 are provided outside the two outermost connecting transverse plates 2. This eliminates the need for additional alignment when inserting the mounting risers into the corresponding mounting slots on the connecting transverse plates. The baffles on both sides easily ensure that adjacent mounting risers are flush, thereby ensuring that the vertical slots on adjacent mounting risers are aligned side by side.

[0026] Among them, the top end of the fixed side plate 1 is bent outward to form an inclined plate 11. The inclined plates on both sides are mainly for the convenience of the operator to hold and put down the fixture from both sides of the fixture, which is equivalent to an angled handle.

[0027] The bottom plane of the fixed side plate 1 is coplanar with the bottom plane of the connecting horizontal plate 2. This ensures the stability of the fixture placement and ensures the safe use and smooth operation of the fixture.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
