Description

Technical Field

[0001] This application relates to the technical field of diameter reduction machines, and in particular to a hydraulic diameter reduction machine. Background Technology

[0002] As a non-cutting machining equipment, the diameter reduction machine has many advantages, such as simple production process, low operation difficulty, effective saving of raw materials, and relatively stable product quality. Its working principle utilizes hydraulic technology to feed the portion of round steel, rebar, or other materials requiring diameter reduction into a special mold, where it is compressed and shaped. The density of the compressed steel is significantly increased, thereby improving the material's compressive strength, while maintaining its plasticity and impact toughness, thus solving the problem of reduced compressive strength and impact toughness caused by lathe peeling.

[0003] In related technologies, before the workpiece enters the reduction mill, a layer of oil is usually brushed onto the workpiece surface to reduce the friction coefficient between the workpiece and the reduction mill mold and to accelerate the dissipation of heat generated during friction and deformation. However, the brushing process is affected by factors such as worker skill and working conditions, making it difficult to guarantee the uniformity and effectiveness of the oil application. This may result in poor lubrication and heat dissipation for some workpieces, affecting the reduction mill quality and increasing the defect rate. Furthermore, during manual oiling, workers are frequently exposed to lubricating oil, which may have adverse effects on their health in the long run. Therefore, there is an urgent need to develop a technical solution that can replace manual oiling and improve its efficiency and quality to solve the problem of low efficiency in manual oiling during existing reduction mill processing. Utility Model Content

[0004] To improve the oiling efficiency of reducing the diameter of workpieces, this application provides a hydraulic reducing machine.

[0005] The hydraulic compression compressor provided in this application adopts the following technical solution:

[0006] A hydraulic reducing machine includes a reducing machine body. A support frame is installed in front of the feed end of the reducing machine body. An oil storage tank is fixedly connected to the upper end of the support frame. An oil outlet pipe is fixedly connected and communicated with the lower end of the oil storage tank. An oil control valve is installed on the oil outlet pipe. Two opposing arc-shaped plates are provided between the support frame and the feed end of the reducing machine body. When a workpiece enters the reducing machine body, the workpiece passes between the two arc-shaped plates. Multiple brush plates are provided on the arc-shaped plates. Brush bristles for brushing the workpiece are fixedly connected to the brush plates. A fixing component for fixing the brush plates and the arc-shaped plates is provided between the brush plates and the support frame. A connecting component for connecting the two is provided between the arc-shaped plates and the support frame.

[0007] By adopting the above technical solution, before the workpiece enters the hydraulic reducing machine, the oil control valve can be opened, allowing the lubricating oil in the oil reservoir to fall onto the workpiece through the oil outlet pipe. Subsequently, as the workpiece moves inside the reducing machine, the lubricating oil falling on the side wall of the workpiece can contact multiple brushes on the arc plate, thereby evenly applying the lubricating oil to the workpiece through the brushes. Thus, the application of lubricating oil to the workpiece can be achieved during the process of the workpiece entering the hydraulic reducing machine, improving the oiling efficiency of the reducing workpiece.

[0008] Optionally, an oil guide rope is fixedly connected to the outlet of the oil pipe.

[0009] By adopting the above technical solution, the lubricating oil discharged from the oil outlet pipe can fall onto the workpiece through the oil guide rope, thereby reducing the splashing of oil droplets when they fall onto the workpiece.

[0010] Optionally, a plurality of oil distribution ropes are fixedly connected to the end of the oil guide rope away from the oil outlet.

[0011] By adopting the above technical solution, the oil droplets falling from the guide rope can be dispersed by the oil distribution rope, thereby improving the uniformity of lubricant distribution.

[0012] Optionally, the fixing component includes a plurality of countersunk bolts, each of which corresponds to a brush plate and is threadedly connected to the brush plate and the arc plate.

[0013] By adopting the above technical solution, the brush plate can be disassembled from the arc plate by rotating the countersunk bolt, and the brush plate can be replaced in a timely manner.

[0014] Optionally, each of the two arc-shaped plates has a sliding groove on one side that is close to each other. The sliding groove is arranged along the length direction of the arc-shaped plate, and the brush plate is slidably connected in the sliding groove.

[0015] By adopting the above technical solution, the position of the brush plate can be restricted by the chute, thereby improving the stability of the brush plate within the chute.

[0016] Optionally, the connecting assembly includes a slide rod passing through the support frame, one end of the slide rod being fixedly connected to the arc-shaped plate, the support frame being provided with a locking member for fixing the slide rod to the support frame, and the arc-shaped plate being made of rubber.

[0017] By adopting the above technical solution, the arc-shaped plate can be fixed on the support frame by means of a sliding rod.

[0018] Optionally, the locking component is configured as a locking bolt, and the slide rod has a plurality of threaded holes equidistantly arranged along the length direction of the slide rod. The locking bolt is threadedly connected to the support frame, and the shank of the locking bolt is threadedly connected to the threaded hole.

[0019] By adopting the above technical solution, the slide bar can be fixed on the support frame by rotating the locking bolt.

[0020] Optionally, the slide bars are configured as a plurality of ones and are equidistant from each other along the height direction of the arc-shaped plate.

[0021] By adopting the above technical solution, the curvature of the arc plate can be changed by adjusting the position of each slide rod, so that the curvature of the arc plate fits the arc surface of the workpiece to be processed more closely.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The lubricating oil can be evenly applied to the workpiece by the brush plate, thereby achieving the application of lubricating oil on the workpiece during the process of the workpiece entering the hydraulic reduction machine, which improves the oiling efficiency of reducing workpiece.

[0024] 2. The oil distribution rope can disperse the oil droplets falling from the guide rope, thereby improving the uniformity of lubricant distribution;

[0025] 3. The position of the brush plate can be restricted by the slide groove, which improves the stability of the brush plate within the slide groove. Attached Figure Description
