Description

Technical Field

[0001] This utility model belongs to the field of alloy sintering technology, specifically relating to a tungsten alloy rod tray for sintering. Background Technology

[0002] After machining, tungsten alloy rods require sintering for mechanical property adjustments. Typically, the rods are placed directly in a tray and fed into a sintering furnace. However, due to limited tray capacity, multiple trays can be stacked together before sintering to improve efficiency. But this process has been found to cause tilting and tipping if the stacking height is too high, and the rods exhibit low stability during loading and unloading, hindering batch sintering and affecting efficiency and quality. Therefore, a tungsten alloy rod tray for sintering is needed to address these technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a tungsten alloy rod tray for sintering, comprising a tray body; the upper surface of the tray body is provided with a placement area, the placement area having multiple placement grooves, the tungsten alloy rods being placed in the placement grooves, the multiple placement grooves being evenly arranged along the width direction of the tray body, the length of the placement grooves being parallel to the length of the tray body, and support members being provided on both sides of the tray body corresponding to the placement area, the support members including mutually cooperating support protrusions and limiting grooves, the support protrusions being parallel to the placement grooves, and the support protrusions and limiting grooves being respectively provided on two surfaces of the tray body.

[0004] Preferably, the supporting protrusion and the placement groove are both located on the upper surface of the pallet body, and the limiting groove is located on the lower surface of the pallet body.

[0005] Preferably, the limiting groove and the placement groove are both located on the upper surface of the pallet body, and the supporting protrusion is located on the lower surface of the pallet body.

[0006] Preferably, one end of the limiting groove extends to the edge of the tray body and is connected to a flared opening. This design facilitates pushing the support protrusion on the lower surface of the upper tray body into the limiting groove of the lower tray body, achieving a match between the support protrusion and the limiting groove without precise alignment. This improves stacking efficiency and reduces the wobbling of the tungsten alloy rod during stacking.

[0007] Preferably, each end of the tray body is provided with a rotatable baffle. The baffle is perpendicular to the placement groove and is hinged to both ends of the tray body via a hinge shaft, which is a damping shaft. When the tray is filled with tungsten alloy rods, rotating the baffle causes it to stand upright, thus preventing the tungsten alloy rods from coming out of the placement groove and further improving stability during movement.

[0008] This invention also includes other components that enable the normal use of a tungsten alloy rod tray for sintering, all of which are conventional techniques in the art. Furthermore, devices or components not specified in this invention, such as damping shafts, all employ conventional techniques and equipment in the art.

[0009] Working principle: The tungsten alloy rods to be sintered are placed in the placement groove. The tungsten alloy rods are arranged in a matrix on the tray body. After the tray body full of tungsten alloy rods is stacked together, it is put into the sintering furnace. During stacking, the support ridge is located in the limiting groove of the corresponding other tray body, which makes the stacked tray body more stable and helps to improve the stability of the transportation process.

[0010] The beneficial effects of this utility model are: the structure is simple and reasonable, which can efficiently and stably stack the tray body filled with tungsten alloy rods, and can sinter tungsten alloy rods in batches. The transportation and transfer of tungsten alloy rods during the sintering process is more stable, and the sintering efficiency is high and the effect is good. Attached Figure Description
