Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a hard alloy end mill for processing stainless steel. Background Art

[0002] Stainless steel is the abbreviation of stainless acid-resistant steel. It is a material that is resistant to weak corrosive media such as air, steam, and water. Milling cutters are rotating tools with one or more teeth used for milling. They are mainly used to process planes, steps, and grooves on milling machines. They are used to form surfaces and cut workpieces. Milling cutters come in a variety of shapes and are suitable for different working environments.

[0003] However, the existing milling cutters have the following problems: after long-term use, the milling cutter will produce wear and loss, which affects the processing. When the milling cutter is replaced, it may be necessary to remove the bolts used for connection or remove the parts connecting the milling cutter and the connecting cylinder through additional parts, which is relatively inconvenient. In addition, in the event of accidental damage, the wrench and parts for disassembly and assembly cannot be found in time, which can easily affect the processing of the workpiece and reduce production efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that when replacing the milling cutter, it may be necessary to disassemble the bolts used for connecting it or disassemble the components connecting the milling cutter and the connecting cylinder through additional components, which is inconvenient. In addition, in the event of accidental damage, the wrench and components for disassembling and assembling it cannot be found in time, which easily affects the processing of the workpiece and reduces production efficiency. A carbide end mill for stainless steel processing is proposed to solve the problems in the prior art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A carbide end mill for machining stainless steel, comprising a milling cutter body and a connecting cylinder, wherein one end of the milling cutter body is provided with a cutter head, the other end of the milling cutter body is provided with a connecting column, the connecting cylinder is located outside the other end of the milling cutter body, the connecting cylinder is slidably sleeved on the other end of the milling cutter body, the outer side of the milling cutter body is sleeved with a collar for facilitating connection with the connecting cylinder, and the collar is provided with four movable grooves;

[0007] The fixing mechanism is arranged on the collar and is used for fixing the connection between the milling cutter body and the connecting cylinder.

[0008] In a possible design, the fixing mechanism includes four rotating handles, four threaded columns, four clamping blocks, four clamping grooves and a clamping ring. The clamping ring is fixedly sleeved on the outside of the connecting tube, and the bottoms of the four rotating handles are fixedly connected to the No. 1 column. One end of the four No. 1 columns passes through the outside of the ring and is fixedly connected to one end of the threaded column. The two ends of the four threaded columns are respectively rotatably connected to the top inner wall and the bottom inner wall of the four movable grooves. The four clamping blocks are respectively threadedly sleeved on the outsides of the four threaded columns. The two sides of the four clamping blocks are respectively slidably connected to the two side inner walls of the four movable grooves. The four clamping grooves are respectively arranged on one side of the bottom of the four clamping blocks. The four clamping grooves are all matched with the same clamping ring, and the four clamping blocks are all clamped with the same clamping ring through the clamping grooves.

[0009] In a possible design, four rubber pads are fixedly connected to one side of the collar to reduce damage caused by collision between the connecting tube and the collar.

[0010] In a possible design, four slots are provided on one side of the connecting tube, and plug posts are provided inside the four slots. One end of the four plug posts passes through one side of four rubber pads respectively and is fixedly connected to one side of the same ring.

[0011] In a possible design, sliders are fixedly connected to both sides of the four blocks, and sliding grooves adapted to the sliders are provided on the inner walls on both sides of the movable groove on the ring, and the multiple sliders are slidably connected to the multiple sliding grooves respectively.

[0012] In a possible design, the cutter head of the milling cutter body is made of tungsten steel, and the surface of the cutter head of the milling cutter body is provided with a coating made of titanium nitride.

[0013] In the present application, when in use, first, the milling cutter body is made of high-hardness tungsten steel material, which ensures the cutting efficiency and durability of the tool. The titanium nitride coating on the surface of the cutter head further improves the wear resistance and cutting performance. The connecting cylinder is designed to be slidably sleeved on the outside of the connecting column of the milling cutter body, and a fixed mechanism is used to achieve a stable connection between the two. When the milling cutter body and the connecting cylinder need to be connected, the rotating handle is first rotated to drive the No. 1 column and the threaded column fixedly connected to it to rotate. Since the clamping block is threadedly sleeved on the threaded column, and the two sides of the clamping block are slidably connected to the inner walls of the two sides of the movable groove, the sliding groove on the collar is adapted to the sliders on both sides of the clamping block, which reduces the clamping block from moving. The friction and wear during movement ensure the smooth operation and long-term use of the fixing mechanism. As the threaded column rotates, the block will move downward along the threaded column. During the movement, the slot at the bottom of the block gradually approaches and is finally completely stuck in the clamping ring on the outside of the connecting cylinder, thereby achieving a stable connection between the milling cutter body and the connecting cylinder. In addition, in order to further enhance the connection stability between the connecting cylinder and the collar, a slot and column structure is specially designed. After the relative position of the collar and the connecting cylinder is adjusted, the column can be inserted into the slot to increase the additional fixing effect and prevent the milling cutter body and the connecting cylinder from sliding relative to each other due to vibration or external force during processing.

[0014] The beneficial effects of the utility model are:

[0015] In the utility model, a firm connection between the milling cutter body and the connecting cylinder is achieved through the components such as the threaded column, the clamping block and the clamping ring in the fixing mechanism, thereby ensuring stability and safety during the processing. At the same time, it is also convenient for disassembly and assembly of the milling cutter body, and further, after the equipment has been working for a long time, it is convenient to disassemble, assemble and replace the milling cutter, thereby ensuring working effect and efficiency.
