Background technique

In the field of machining, milling cutters or/and drills are widely used machining tools. The raw materials for manufacturing milling cutters or/and drills are usually tungsten carbide (WC) powder metallurgy round rods, and the specifications and sizes of the round rods vary. The milling cutter or drill bit depends on the specifications, and the length (such as 250-400mm) is determined by a cutting device. Before the utility model, those skilled in the art have designed cut-to-length devices of different structural shapes, i.e. cut-to-length machines, which each have their own characteristics and have played their respective strengths; but the biggest deficiency is the powder metallurgy rod The dust (that is, waste material) generated during the cut-to-length process cannot be collected well, polluting the environment, and the remaining materials are not well collected and processed, resulting in waste of raw materials and increasing the cost burden of the enterprise.

Contents of the invention

The purpose of the utility model is to provide a powder metallurgy rod cut-to-length device that can centrally collect the dust (waste) and other materials generated during the cut-to-length process of WC powder metallurgy rods.

In order to achieve the above object, the technical solution adopted by the utility model is: the described powder metallurgy rod cut-to-length device includes a waste material collection hopper, a first collection pipe and a second collection pipe, a waste material lowering hopper, a bracket, a moving material plate, The collecting cover, the positioning block at the material end, the fixed frame, the cutter head, the material sizing positioning block, the multi-way pipe, and the material sizing block have a fixed frame on the top plate of the square bracket, and the moving material plate is arranged on the fixed frame. On the frame, a material end face positioning block is arranged on the front edge of the moving material plate. On the opposite side of the material end face positioning block, there are fixed size blocks with a quantity greater than or equal to 1 on the moving material plate, and the position is on the top of the moving material plate. The collection cover on the surface is connected with the head end of the second collection pipe. In the collection cover, there is a material fixed-length positioning block fixedly connected to the upper surface of the moving material plate (the material fixed-length positioning block is on the same horizontal line as the material end face positioning block), and a cutter head is installed on the fixed frame in the collection cover. (The cutter head is driven by a special transmission mechanism).

The tail end of the second collection pipe is connected with the inlet of the right end of the multi-way pipe, the upper port of the waste material lower hopper installed on the lower side of the support top plate faces the discharge groove of the collection cover, and the lower end outlet of the waste material lower hopper is the same as the first collection pipe The head end of the first collection pipe is connected to the middle inlet of the multi-way pipe, the middle outlet of the multi-way pipe is connected to the waste collection bucket, and the left end outlet of the multi-way pipe is connected to the dust removal box with an exhaust fan.

Compared with the existing technology, the metallurgical rod sizing and cutting device provided by the above technical scheme has the following technical effects: ① The dust (waste) generated during the sizing and cutting of powder metallurgy rods is collected by double collection pipes . A second collection pipe connected (communicated) with the collection cover is installed on the upper surface of the moving material plate, and the dust that flies upward during the cutting process of the material (powder metallurgy rod) enters the second collection pipe after passing through the collection cover. ; while the dust falling down during the cut-to-length process of the material (powder metallurgy rod) enters the first collecting pipe through the waste hopper and is taken away, so all dust (waste) is collected in a relatively sealed system.

② A waste collection bucket is installed at the middle end of the multi-way pipe connecting the first collection pipe and the second collection pipe. Most of the dust (waste) from the first collection pipe and the second collection pipe falls into the waste collection bucket Unified collection, a very small part of the dust is sucked from the end connected to the dust removal box into the dust removal box for centralized collection. Usually, an exhaust fan is installed on the dust removal box.

③ The remaining material after the powder metallurgy rod is cut to length (cut) is collected as recycled material and reused.
