Detailed implementation manners

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-6 As shown, a discharge mechanism of a cold heading machine according to an embodiment of the present utility model includes a cold heading machine body 1. A discharge port 10 is provided on one side of the cold heading machine body 1. A base 2 is arranged on one side of the discharge port 10. A vibration mechanism is arranged on the top of the base 2 and the vibration mechanism is connected to a filter oil tank 3. A plurality of filter plates 30 are distributed in a stepped manner in the filter oil tank 3. A cleaning component is arranged at the rear end of each filter plate 30 inside the filter oil tank 3. The cleaning component is used to clean the oil liquid on the surface of the workpiece.

[0023] During use, the workpiece is discharged from the discharge port 10 after being processed by the cold heading machine body 1 and falls into the filter oil tank 3. The vibration mechanism works and drives the filter oil tank 3 to vibrate. While the filter oil tank 3 vibrates, it drives each filter plate 30 inside it to vibrate. The vibration of the workpiece causes the oil liquid on its outside to separate and drain down to the bottom of the filter oil tank 3 through the filter plates 30;

[0024] Since the sieve plates are distributed in a stepped manner, the vibration of each filter oil tank 3 causes the workpiece to slide down step by step along each sieve plate. A cleaning component is arranged at the rear end of each filter plate 30 inside the filter oil tank 3. Each cleaning component further cleans the oil liquid on the surface of the workpiece, effectively improving the cleaning effect of the discharge mechanism on the oil liquid on the surface of the workpiece and improving the practicability of the equipment.

[0025] The filter plate 30 is arranged with its rear end inclined downward, and a number of material guiding grooves 31 are arrayed and opened at the top. The cross-section of the material guiding groove 31 is in a V-shaped structure, and a number of filter holes 32 are arrayed and opened on the inner bottom wall.

[0026] During use, by arranging the material guiding grooves 31, the workpieces are fed in batches, effectively avoiding the accumulation of workpieces. The opening of the filter holes 32 facilitates the downward discharge of the separated surface of the workpieces.

[0027] The cleaning assembly includes a pivot 4 rotatably arranged inside the filter oil tank 3, a brush roller 40 fixed to the outside of the pivot 4, and bristles 41 located outside the brush roller 40. On one side of each brush roller 40 inside the filter oil tank 3, an extrusion roller 42 for extruding the bristles 41 is fixedly arranged.

[0028] During use, the workpieces slide down along the inclined surface of the filter plate 30 and sequentially pass through the cleaning assemblies at the rear ends of each filter plate 30. The cleaning assembly includes the pivot 4 and the brush roller 40 fixed to the outside of the pivot 4. The rotation of the pivot 4 drives the rotation of the brush roller 40 and drives the bristles 41 to clean and collect the lubricating oil on the surface of the workpieces.

[0029] Furthermore, an extrusion roller 42 is arranged on one side of each pivot 4. The brush roller 40 rotates and causes the outer bristles 41 to pass through the extrusion roller 42. The extrusion roller 42 extrudes and discharges the oil adsorbed by the bristles 41 outside the brush roller 40, so that the bristles 41 can more efficiently clean the oil on the surface of the workpieces.

[0030] One end of each pivot 4 passes through the filter oil tank 3 and is connected with a pulley, and each pulley is connected with a driving belt. During operation, the driving belt is connected with an external driving source 25 to drive the synchronous rotation of each pivot 4, and further drive the synchronous operation of each brush roller 40. The connection and cooperation of the pulley, the driving belt and the external driving source 25 are all prior arts and will not be elaborated here.

[0031] An opening 33 is formed at the rear side of the filter oil tank 3. An outlet inclined plate 34 is arranged at the rear end of the last filter plate 30 corresponding to the opening 33. A finished product collection box 35 is arranged on the top surface of the base 2 corresponding to the outlet inclined plate 34.

[0032] During use, the workpieces slide down along each filter plate 30 in sequence. After passing through the cleaning assembly at the rear end of the lowermost filter plate 30, they fall onto the outlet inclined plate 34 and are guided by the outlet inclined plate 34 to the finished product collection box 35 for collection.

[0033] A oil baffle 36 is fixedly arranged at the bottom of the opening 33. An oil discharge port 37 is opened on the inner bottom wall of the filter oil tank 3 inside the oil baffle 36. An oil collection box 38 is arranged on the top surface of the base 2 corresponding to the oil discharge port 37.

[0034] During use, the oil on the surface of the workpiece is separated from the workpiece through the action of vibration and the cleaning component and is discharged downward through the filter holes 32 of the filter plate 30 to the bottom of the filter oil tank 3. Then, the oil is discharged from the filter oil tank 3 through the oil discharge port 37 and collected in the oil collection tank 38.

[0035] At the four corners of the top surface of the filter oil tank 3 on the top surface of the base 2, four support frames 20 are provided. At least one spring member 21 is provided at the top of the support frame 20. The upper end of the spring member 21 is connected to a support seat 22, and the support seat 22 is fixedly connected to the filter oil tank 3 through a fixed shaft 23.

[0036] During use, by providing multiple support frames 20 to support the filter oil tank 3, two spring members 21 are provided at the top of each support frame 20. The upper ends of the two spring members 21 are commonly connected to a support seat 22. The spring members 21 provide support for the filter oil tank 3, and when the filter oil tank 3 vibrates, the spring members 21 will only deform but will not cause the support seat 22 to be separated from the spring members 21. The support frames 20 provide stable support for the filter oil tank 3 and at the same time ensure the stable vibration of the filter oil tank 3.

[0037] The vibration mechanism includes a fixed frame 24 fixedly arranged on the top surface of the base 2. A driving source 25 is provided at the top of the fixed frame 24, and an output shaft of the driving source 25 is connected to a sector block 26. An eccentric wheel 27 is fixedly arranged at the center of the side wall of the filter oil tank 3, and the sector block 26 is eccentrically connected to the eccentric wheel 27.

[0038] During use, the driving source 25 includes an asynchronous motor fixedly installed on the top of the fixed frame 24. The asynchronous motor is drivingly connected to a speed reducer, and an output shaft of the speed reducer is connected to the sector block 26 through a coupling. When working, the asynchronous motor is started and the sector block 26 is driven to rotate through the speed reducer. The sector block 26 is eccentrically connected to the eccentric wheel 27, thereby driving the eccentric wheel 27 to perform eccentric motion to drive the filter oil tank 3 to vibrate.

[0039] All the electrical components appearing in this article are electrically connected to an external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.
