Description

Technical Field

[0001] The utility model relates to the technical field of cutting tool production, in particular to a novel ball milling device. Background Art

[0002] CNC tools account for a considerable proportion of mechanical cutting tools. In a broad sense, cutting tools include not only cutting tools but also grinding tools. In the existing tool production technology, CNC tools are mostly metal powders. During the ball milling mixing process, the collision and friction between the metal powder, grinding balls and the ball mill tank will generate a lot of heat, causing the tank to rise steadily. Excessive temperature will cause the ball milling performance to decline and may also cause the metal powder to oxidize, affecting the quality of the final tool.

[0003] Existing ball mills generally use water spraying to dissipate heat during operation. However, the water on the surface of the tank is difficult to recover, and some water may be thrown out when the tank rotates. At the same time, this water has a certain temperature due to the absorption of heat, and there is a certain risk of scalding for people passing by. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses a novel ball milling device, and the technical scheme adopted is that it includes a base plate, a ball mill, a return water tank, a return water port, a condenser, a condenser water inlet, a water tank, a water outlet, a control device, an L-shaped mounting frame, mounting screws, a lower adjustable mounting structure, a fan, an electrical box, an upper fixed shaft, a shielding structure, a top rod body, a set frame, a middle hole, a water inlet and a spray head. The ball mill is fixedly mounted on the base plate, and a condenser and a water tank connected to each other are fixed on the left side of the base plate. A water outlet pump and a circulating pump are arranged in the water tank. The water outlet pump provides a water source for spray cooling, and the circulating pump is used for recycling return water. The condenser water inlet of the condenser is connected to the return water port of the return water tank through a hose. The L-shaped mounting frame is fixed to the base plate by mounting screws. This mounting method makes the L-shaped mounting frame detachable and positionable. The lower half of the L-shaped mounting frame is provided with a lower adjustable mounting structure, through which the fan and the electrical box are installed. The installation structure can adjust the position of the fan and its angle toward the ball mill according to needs. The electrical box has a battery and a controller, which respectively power and control the fan. An upper fixed shaft is integrally formed on the inner side of the upper half of the L-shaped mounting frame, and a shielding structure is arranged between the two upper fixed shafts. This structure is used to shield the water that may be thrown out of the ball mill during rotation to prevent it from splashing the operator. While shielding, it can also guide it so that it finally enters the return water tank for subsequent recycling and reuse. A top rod body is fixed on the top of the L-shaped mounting frame, and through slots are opened at both ends of the set frame. The top rod body is set through the slots. A middle hole is opened in the middle of the rod body connected between the tops of the L-shaped mounting frame. The interior of the set frame is a cavity connected to the spray head arranged below it and the water inlet arranged on the side. The hose connected to the water outlet passes through the middle hole and is connected to the water inlet. The water outlet pump is started to supply water, and the spray head sprays water to cool the cylinder of the ball mill.

[0005] As a preferred technical solution of the utility model, the adjustable mounting structure at the bottom includes a through groove, a stabilizing shaft, a set block, a locking portion and a rotating connecting rod. The lower halves of the two L-shaped mounting frames have through grooves in the left and right directions, in which the stabilizing shafts are fixed. The set blocks are placed in the through grooves, and have through holes in the upper and lower directions, which are set on the stabilizing shafts through the through holes. A locking portion is set on the side of the L-shaped mounting frame to lock the position of the set blocks. The rotating connecting rods are rotatably installed on the inner sides of the front and rear set blocks, and a mounting plate is fixed between the two rotating connecting rods. A fan and an electrical box are installed on the mounting plate. Since the lower end of the rotating connecting rod is in contact with the upper surface of the bottom plate but not connected, when the height of the set block is changed, the angle of the rotating connecting rod will change. Therefore, the angle of the mounting plate changes, and at this time, the position of the fan and its direction angle are changed.

[0006] As a preferred technical solution of the utility model, the locking part includes a screw hole and a locking screw. The lower half of the L-shaped mounting frame is provided with a plurality of screw holes connected to the through slot. The locking screw is installed in cooperation with the screw hole and extends into the through slot to lock the set block.

[0007] As a preferred technical solution of the utility model, the shielding structure includes a rotating mounting plate, a water retaining net, a raised shaft, a connecting rope and a rope winder. The rotating mounting plate is rotatably connected between two upper fixed shafts. The middle area of ​​the rotating mounting plate is through-shaped, and several layers of water retaining nets are distributed therein. Raised shafts are integrally formed on the left and right ends of the upper side of the rotating mounting plate. One end of the connecting rope is fixedly connected to the raised shaft, and the other end is connected to the output end of the rope winder arranged on the L-shaped mounting frame. This rope winder is powered by a battery and is equipped with a separate switch.

[0008] As a preferred technical solution of the utility model, the water retaining net is three-layered, and the meshes of each layer are staggered. The scale grooves are evenly distributed on a top rod body, which can accurately control the moving distance of the set frame so that it is directly above the ball mill, achieving a good spray cooling effect.

[0009] The beneficial effects of the utility model are as follows: by arranging a shielding structure on the L-shaped mounting frame, the ball mill is prevented from throwing out surface water due to its rotation, especially when the cylinder temperature of the ball mill is high, the water on its surface used for cooling also has a certain temperature after absorbing heat, and there is a certain risk of scalding. This structure can provide protection and at the same time guide the blocked water so that it can eventually enter the water tank for recycling. The fan installed by the adjustable mounting structure below blows air at the bottom for cooling, and also dries the residual moisture on the outer wall of the cylinder, thereby improving the cooling effect.
