Description

Technical Field

[0001] The present application relates to the field of metal processing equipment, and in particular to a cooling device for producing hard alloy tool heads. Background Art

[0002] Alloy cutting tools generally refer to cemented carbide, an alloy material made of hard compounds of refractory metals and bonding metals through a powder metallurgy process. In the alloy cutting tool manufacturing process, it is necessary to select alloy materials of appropriate hardness according to customer needs, and then reasonable chamfering, rough grinding and fine grinding are required according to the corresponding process. In general processing plants, this process will use a five-axis grinding machine tool and use a grinding wheel for continuous grinding to improve processing efficiency. When the grinding wheel cuts the workpiece, a large amount of heat will be generated, and the cutting fluid can cool it down to prevent the workpiece from burning.

[0003] The existing cooling method is usually to add a water spray pipe next to the alloy tool during the cutting process. The water or cooling oil sprayed from the water pipe flushes the tool cutting position, which will take away the heat generated by the cutting process. However, the sprayed water will splash onto the surrounding equipment or the ground, and impact the metal chips generated during the cutting process and scatter them randomly, affecting the processing environment of the tool cutting. Utility Model Content

[0004] In order to reduce the impact of cooling operations on the processing environment of hard alloy tooling, the present application provides a cooling device for hard alloy tooling production.

[0005] The present application provides a cooling device for hard alloy tool production using the following technical solution:

[0006] A cooling device for producing hard alloy cutting tools comprises a workbench with a fixture, two partitions arranged on the workbench, pipes connected to both ends of the partitions and a cooling pool connected to the pipes, the pipes are connected to a pump, the cooling pool is filled with coolant, and the horizontal height of the partition is greater than the horizontal height of the fixture.

[0007] A further technical solution is that a fixing device is provided at the end of the pipeline connected to the cooling pool, and a filter is fixedly provided on the fixing device.

[0008] A further technical solution is that the fixing device includes a convex ring protruding from the inner wall of the cooling pool, the convex ring is provided with a slot, the filter includes a clamping ring and a mesh body arranged on the clamping ring, and the clamp is provided with a clamping strip matching the slot.

[0009] This application has the following beneficial technical effects:

[0010] During the cutting process of hard alloy tools, the coolant can enter the gaps between the partitions and completely immerse the alloy tools and fixtures. The pump can provide flow power for the coolant, so that the coolant can circulate. While cooling the cutting position, it can also take away the metal debris generated by cutting, greatly improving the working environment of the hard alloy tools. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0016] The present application embodiment discloses a cooling device for producing hard alloy cutting tools. Figure 1~Figure 3 The device includes a workbench 1 with a fixture 11, two partitions 12 arranged on the workbench 1, a pipe 3 connected to both ends of the partition 12 and a cooling pool 2 connected to the pipe 3, the pipe 3 is connected to a pump 4, the cooling pool 2 is filled with coolant, and the horizontal height of the partition 12 is greater than the horizontal height of the fixture 11.

[0017] Reference Figure 1 and Figure 2 The workbench 1 is a platform for cutting operations. The partition 12 is arranged on the side of the workbench 1 and is perpendicular to the workbench 1. The two ends of the partition 12 are flush with the two end surfaces of the workbench 1. The pipeline 3 includes a hard pipe body 31 and a flange 32 connected to the end of the hard pipe body 31 and having a rectangular structure. The pipeline 3 is connected to the workbench 1 through the flange and the gap between the pipeline 3 and the partition 12 is connected. The horizontal height of the upper end of the cooling pool 2 is not higher than the surface of the workbench 1, which is used to prevent the coolant from being continuously infused into the gap between the inner box of the pipeline 3 and the partition 12 due to gravity.

[0018] During the working process, the metal workpiece to be processed is clamped on the fixture 11, and a coolant is added to the cooling pool 2. The coolant can be cooling water or cooling oil. The coolant is passed through the pipe 3, the gap between the partitions 12 and the cooling pool 2 by the action of the pump 4, forming a circulation to cool the metal workpiece and the hard alloy tool located between the partitions 12, and avoid the splashing of the coolant affecting the working environment of the hard alloy tool.

[0019] Reference Figure 3 The end of the pipe 3 connected to the cooling pool 2 is provided with a fixing device, and the fixing device is fixedly provided with a filter screen 5. Specifically, the fixing device includes a convex ring 6 protruding from the inner wall of the cooling pool 2, and the convex ring 6 is provided with a clamping groove 61. The filter screen 5 includes a clamping ring 51 and a mesh body 53 provided on the clamping ring 51, and the clamping ring is provided with a clamping strip 52 matched with the clamping groove 61.

[0020] The filter screen 5 is used to allow the coolant to pass through and intercept the metal debris carried in the coolant. The slot 61 runs through the upper end of the convex ring 6. The cross-sections of the slot 61 and the clamping strip 52 are both trapezoidal structures. During installation, the clamping ring 51 can be inserted from top to bottom so that the clamping strip 52 is clamped in the slot 61 to fix the filter screen 5 and prevent the filter screen 5 from detaching from the convex ring 6 laterally. When a lot of metal debris accumulates in the filter screen 5, the filter screen 5 can be slid upward from the convex ring 6 to be removed, and the metal debris in the filter screen 5 can be cleaned or replaced with a new filter screen 5. This can prevent the metal debris from damaging the pump 4 and improve the safety during the cooling process.
