Description

Technical Field

[0001] The utility model relates to the technical field of electrode extruder shearing, in particular to an energy-saving electrode extruder quick shearing device. Background Art

[0002] After the electrode green billet is extruded, it is sheared and extruded by manual button control. The same operation is repeated for each electrode. The labor intensity of workers is high, the production efficiency is low, the cross-section of the green billet is uneven, the accuracy is poor, which affects the homogeneity of the product, the accumulated losses are large, and the production cost is high.

[0003] In the prior art, a plunger pump is usually used to supply oil to the oil cylinder of the shear cutter through a pipeline, and then the electrode green billet is sheared. Due to the inconsistent length of the existing pipelines, the resistance is different, so that the pressure obtained by the cutter oil cylinder is also different, and the cutter has no stable incremental output during the shearing process, resulting in the cutter moving asynchronously during the shearing process. The electrode green billet is subjected to external forces of different speeds, and the cross-section of the electrode cut cannot be flat. Moreover, after the cutter completes the shearing action of each green billet, the hydraulic plunger pump is still in a non-standby state while waiting for the next shearing, and the power and energy loss continues, without utilizing the non-working state to effectively store energy.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide an energy-saving electrode extruder quick shearing device to solve the shortcomings of the prior art. Utility Model Content

[0005] The utility model aims to avoid the deficiencies of the prior art and provide an energy-saving electrode extruder quick shearing device. The energy-saving electrode extruder quick shearing device realizes the pressure-stabilizing incremental output during shearing by connecting an energy storage mechanism between the driving hydraulic cylinder and the hydraulic oil pump. The energy storage mechanism is located closer to the shearing cylinder than the original hydraulic oil tank, so that the pressure loss can be better compensated, the pressure difference between the left and right shearing cylinders can be reduced, the shearing speed of the shearing machine can be increased, the shearing time can be reduced, the root shearing of the electrode can be facilitated, the shearing section of the electrode green billet can be flattened, the product quality can be improved, the effective energy storage in the non-operating state can be utilized, the production efficiency can be improved, and the energy-saving effect can be achieved.

[0031] The utility model is further described in conjunction with the following embodiments.

[0032] Example 1.

[0033] like Figure 1-3 As shown, an energy-saving electrode extruder quick shearing device comprises a shearing machine bracket 1, an upper slide 2 and a lower slide 3 are arranged on the shearing machine bracket 1, two cutter positioning plates 4 are slidably installed between the upper slide 2 and the lower slide 3, a shearing knife 5 is fixedly installed on the cutter positioning plate 4, the shearing knife 5 is provided with a shearing blade 6, and the two shearing blades 6 cooperate in shearing, two driving hydraulic cylinders 7 are installed on both sides of the shearing machine bracket 1, a connecting rod 8 is fixedly installed on the output end of the driving hydraulic cylinder 7, the end of the connecting rod 8 away from the driving hydraulic cylinder 7 is fixedly connected to the cutter positioning plate 4, and the connecting rod 8 movably passes through the shearing machine bracket 1.

[0034] The present application is used for shearing the electrode green billet after extrusion to solve the technical problems of uneven shearing section and no effective energy storage. First, the shearing device is fixed by the shearing machine bracket 1, and the two shearing knife positioning plates 4 are fixedly installed with the shearing knife 5. Then, the shearing blades 6 of the two shearing knives 5 cooperate to shear the electrode green billet in the middle. The output of the driving hydraulic cylinder 7 drives the two connecting rods 8 to move toward or in the opposite direction, and at the same time drives the cutter positioning plate 4 to slide inside the upper slide 2 and the lower slide 3, thereby driving the two shearing knives 5 to shear the extruded electrode green billet.

[0035] Equipment supporting plates 9 are provided on both sides of the shearing machine bracket 1, and an energy storage mechanism 10 is fixedly installed on each equipment supporting plate 9. Each energy storage mechanism 10 is connected to the oil inlet of the driving hydraulic cylinder 7 on the corresponding side, and the oil inlets of the two energy storage mechanisms 10 are connected to the hydraulic oil pump 11 at the same time, and the hydraulic oil pump 11 is connected to the oil discharge ports of the two driving hydraulic cylinders 7 at the same time.

[0036] The energy storage mechanism 10 is connected to the oil inlet of the driving hydraulic cylinder 7 to provide energy storage oil supply for the driving hydraulic cylinder 7, so that the output synchronization of the two driving hydraulic cylinders 7 is improved, and the shearing end surface of the electrode green billet is flat. At the same time, the two energy storage mechanisms 10 supply oil through the hydraulic oil pump 11. The two driving hydraulic cylinders 7 discharge oil when driving the shearing knife 5 to retract, and the discharged oil returns to the inside of the hydraulic oil pump 11 to realize the circulation of the oil circuit.

[0037] The energy storage mechanism 10 includes an energy storage shell 101, an inflatable bladder 102 is installed inside the energy storage shell 101, an inflation valve 103 is fixedly installed on the top of the inflatable bladder 102 on the energy storage shell 101, an oil storage cavity 104 is provided outside the inflatable bladder 102 in the energy storage shell 101, an energy storage oil discharge port 105 is provided at the bottom of the oil storage cavity 104, and an energy storage oil inlet 106 is also opened on the oil storage cavity 104.

[0038] The energy storage mechanism 10 fills oil into the energy storage housing 101 through the hydraulic oil pump 11, squeezing the inflatable bladder 102, and the volume of the inflatable bladder 102 is reduced to generate elastic potential energy. When the extruded electrode green billet needs to be sheared, the two driving hydraulic cylinders 7 send oil from the two energy storage oil discharge ports 105 through the elastic potential energy of the two inflatable bladders 102, and then drive the shearing knife 5 to shear the extruded electrode green billet. In this process, the length of the oil circuit is consistent, the output of the two driving hydraulic cylinders 7 is stable and synchronous, the electrode green billet is subjected to external forces of the same speed, and the cross-section of the electrode green billet is smooth.

[0039] The two shearing knives 5, the two shearing knife positioning plates 4 and the two connecting rods 8 are all symmetrically mounted on the shearing machine bracket 1 with the shearing center line F as the symmetry axis.

[0040] The symmetrical installation of the shearing knife 5, the shearing knife positioning plate 4 and the connecting rod 8 can ensure that the electrode green body is sheared by the external force at the same speed under the premise of the same length of the oil path, so as to ensure that the cross section of the electrode green body is flat.

[0041] An electro-hydraulic reversing valve is installed on the hydraulic oil pump 11 .

[0042] The electro-hydraulic reversing valve can perform oil circuit reversal after the electrode green body is sheared, and perform effective energy storage preparation through the energy storage mechanism 10 .

[0043] The filling gas inside the inflatable bladder 102 is nitrogen.

[0044] The nitrogen filled in the inflatable bladder 102 can achieve the effect of being very stable in chemical properties and generally not reacting with other substances.

[0045] By connecting an energy storage mechanism 10 between the driving hydraulic cylinder 7 and the hydraulic oil pump 11, a pressure-stabilizing incremental output is achieved during shearing. The energy storage mechanism 10 is located closer to the shear cylinder than the original hydraulic oil tank, so that the pressure loss can be better compensated, the pressure difference between the left and right shear cylinders is reduced, the shearing speed of the shearing machine is increased, the shearing time is reduced, and it is beneficial to the root shearing of the electrode, the shearing cross-section of the electrode green billet is smooth, the product quality is improved, and the effective energy storage in the non-operating state is utilized to improve the production efficiency and achieve the energy-saving effect.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
