Description

Technical Field

[0001] This utility model belongs to the field of titanium alloy bar processing technology, and specifically relates to a surface cooling device for titanium and titanium alloy bars. Background Technology

[0002] Titanium and titanium alloy bars are important structural materials, and their straightness is a key indicator that directly affects the forming quality, connection performance, and service life of the material. To meet the requirements of high-precision straightness, the current production process mainly adopts coiled materials through uncoiling, pre-straightening, cold drawing, peeling and fine correction, and length cutting. Among these processes, the finishing process after cold drawing plays a decisive role in the final straightness.

[0003] However, during cold drawing, the instantaneous high temperatures generated by the plastic deformation of the material mean that directly peeling the material will exacerbate tool wear. Data shows that the lifespan of uncooled tools is only 30%-40% of that under normal operating conditions. Frequent downtime for tool changes not only increases production costs but also severely restricts the continuous production capacity of the production line.

[0004] To address this technical bottleneck, this invention innovatively develops a surface cooling device for titanium and titanium alloy bars. Through an integrated high-efficiency cooling system, it achieves rapid control of the material surface temperature, significantly improving tool life while ensuring machining accuracy. Summary of the Invention

[0005] To address this problem, this invention incorporates a cooling device to effectively reduce the surface temperature of titanium and titanium alloy bars, thereby extending the service life of cutting tools, reducing downtime, improving production efficiency, and meeting the requirements of automated production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface cooling device for titanium and titanium alloy bars, comprising: a base, one end of a support plate fixedly disposed on the base, and a spiral spray pipe fixedly disposed on the other end of the support plate, one end of the spiral spray pipe being closed by a valve, and the other end being connected to the outlet of a water pump, the inlet of the water pump being placed at the bottom of a water tank through a pipe, and the water tank being placed inside the base;

[0007] A temperature control component is placed on the base, and its heating element is placed inside the water tank.

[0008] One end of the coarse filter screen is connected to the support plate, and the other end is connected to the base. The coarse filter screen is in an inclined state. The fine filter screen is set above the base and is connected to the water tank.

[0009] As a further improvement of this utility model, it also includes a material distribution bin, which is disposed on the base and located at the lower end of the coarse filter screen, and a discharge box is provided at the discharge end of the material distribution bin;

[0010] The loading and unloading box is placed on the base, and the inlet of the loading and unloading box matches the outlet of the discharge box; a screw chip conveyor is also rotatably installed in the material distribution bin.

[0011] As a further improvement of this utility model, multiple water spray holes are provided on the spiral spray pipe.

[0012] As a further improvement of this utility model, a wiping brush is also provided on the base in front of the bar entering the spiral spray pipe.

[0013] As a further improvement of this utility model, the temperature control component maintains the water temperature in the water tank at 4°C.

[0014] As a further improvement of this utility model, the screw chip conveyor is driven by a motor, and the motor is mounted on the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The spiral spray pipes, under the control of the water pump, precisely control the flow rate to achieve multi-point cooling, uniformly and slowly reducing the surface temperature of the bar, effectively avoiding thermal stress concentration. At the same time, the mixture of waste chips and water generated after cooling is filtered through coarse and fine filters and flows back into the water tank, ensuring the purity of the water in the circulating water tank and extending its service life. The separated waste chips are automatically discharged by the screw chip conveyor, reducing the burden of manual cleaning and improving overall operation efficiency.

[0017] The temperature control unit maintains the water temperature at 4℃, ensuring stable cooling performance and preventing deformation of the titanium alloy rod due to excessive temperature difference, thus guaranteeing the stability of the cooling operation. Attached Figure Description

[0023] See Figures 1 to 4 As shown, a surface cooling device for titanium and titanium alloy bars is characterized in that: it includes a base, one end of a support plate is fixedly installed on the base, and the other end of the support plate is fixedly installed with a spiral spray pipe 6. One end of the spiral spray pipe 6 is closed by a valve, and the other end is connected to the outlet of a water pump 2. The inlet of the water pump 2 is placed at the bottom of a water tank 5 through a pipe, and the water tank 5 is placed inside the base.

[0024] Temperature control component 3 is placed on the base, and its heating element is placed inside the water tank 5;

[0025] One end of the coarse filter 9 is connected to the support plate, and the other end is connected to the base. The coarse filter 9 is in an inclined state. The fine filter 10 is disposed above the base and is connected to the water tank 5.

[0026] It also includes a material distribution bin, which is set on the base and located at the lower end of the coarse filter screen 9, and a material discharge box is provided at the discharge end of the material distribution bin;

[0027] The loading and unloading box 12 is placed on the base, and the inlet of the loading and unloading box 12 matches the outlet of the discharge box; a screw chip conveyor 11 is also rotatably installed in the material distribution bin.

[0028] like Figure 1 - Figure 2 As shown, the present invention also includes: a plurality of water spray holes 7 opened on the spiral spray pipe 6; a wiping brush 8 is also provided in front of the rod entering the spiral spray pipe 6 through the base; the temperature control component 3 maintains the water temperature in the water tank 5 at 4°C; the screw chip conveyor 11 is driven by a motor, and the motor is mounted on the base.

[0029] In practical applications, during the conveying process of the bar stock through the external feeding equipment, the surface debris of the titanium alloy bar stock is initially cleaned by the wiping brush 8. After the initial cleaning, the titanium alloy bar stock enters the cleaning space formed by the spiral spray pipe 6. At this time, the water pump 2 is started, and cold water is sprayed evenly through the spray holes 7. The temperature control component 3 ensures that the water temperature is constant at 4℃, effectively cooling the bar stock and removing the waste debris from the surface of the titanium alloy bar stock through water pressure. The waste debris is carried by the water flow through the coarse filter screen 9 to the distribution bin. Finally, during the rotation and conveying process of the screw chip conveyor 11, the waste debris is collected in the loading and unloading box 12 through the discharge box.

[0030] The water that passes through the coarse filter screen 9 is then filtered a second time through the fine filter screen 10. After the second filtration, the water flows back to the water tank 5 for recycling, ensuring water quality and reducing water waste while guaranteeing the surface treatment and cooling quality of the titanium alloy rods.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
