Description

Technical Field

[0001] The utility model relates to the technical field of air pressure separation and stamping surplus kinetic energy recovery and utilization, in particular to a plate separation device. Background Art

[0002] Referring to the prior art CN213162777U punch press automatic loading and unloading device, when punching a workpiece, it is often necessary to use a very thin plate. Figure 1 As shown, the adjacent plates 12 are at atmospheric pressure F 大气压 Under the action of the protective oil film 13, a vacuum cavity 14 is formed between adjacent plates, so that the adsorption tension F of the plate is 拉 Under the action of the pressure, it is easy to cause the adjacent plates to stick together and take out double or multi-layer plates at the same time, and it is impossible to realize the stamping processing of the plates one by one.

[0003] At present, compressed air in compressed air tank products is often used to separate plates that are adhered by oil film, but the cost of purchasing compressed air tank products is high, which will reduce production efficiency. In view of this, developing a device that uses surplus kinetic energy to separate plates can not only make up for the shortcomings of existing technologies, but also effectively recycle the surplus kinetic energy of the punch press and reduce production costs. Utility Model Content

[0004] The utility model aims to provide a plate separation device to solve the technical problem that the cost is high and the production efficiency is reduced when the compressed air storage tank product is used to separate the plates adhered by the oil film in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plate separation device, comprising a main pipeline and a cylinder, a gas storage tank, a switch valve assembly and a nozzle which are sequentially connected to the main pipeline along the gas flow direction, the air inlet end of the main pipeline is connected to the atmosphere, the two air ports of the cylinder are respectively connected to the main pipeline, and a one-way valve is provided on the main pipeline between the two air ports and on the main pipeline between the cylinder and the gas storage tank; the piston rod of the cylinder is fixedly connected to the punch press, the movement direction of the piston rod is consistent with the lifting direction of the punch press, and the nozzle outlet faces the side of the plate.

[0006] The principle of this scheme is:

[0007] In this scheme, the main pipeline is connected to the atmosphere, which is convenient for forming a continuous air supply for the cylinder. On the one hand, it can protect the cylinder, and on the other hand, the cylinder and the punch press can be synchronously raised and lowered to inflate the air tank in single phase to obtain compressed air. The specific process is as follows: when the cylinder rises with the punch press, the air in the chamber above the cylinder enters the chamber below the cylinder through the one-way valve on the main pipeline between the two air ports. When the cylinder descends with the punch press, the air in the chamber below the cylinder enters the air tank through the one-way valve on the main pipeline between the cylinder and the air tank. At this time, the outside air enters the chamber above the cylinder; every time the cylinder completes a "rise-fall" cycle with the punch press, the air tank can be inflated once, and the cycle is repeated to realize the compressed storage of air in the air tank. When it is needed, just open the switch valve assembly, and the compressed air in the air tank can be sprayed out from the nozzle. On the side of the nozzle plate, the compressed air enters between the adjacent plates, destroying the oil film vacuum cavity between the plates, which is convenient for achieving the requirement of taking a plate at a time.

[0008] The advantages of this solution are:

[0009] 1. Compared with the prior art that uses compressed air in compressed air storage tanks to separate the plates adhered by oil film, which requires additional costs, this solution can effectively utilize the surplus kinetic energy of the punch press to form compressed air in the air tank by setting a cylinder piston rod that rises and falls synchronously with the punch press, effectively saving energy and reducing the cost of purchasing compressed air storage tanks.

[0010] 2. This solution provides one-way valves on the main pipeline between the two air ports and on the main pipeline between the cylinder and the air tank, so as to facilitate the "one-way" flow of external air through the cylinder and the air tank, and promote the rapid formation of compressed air in the air tank to supply the required plate separation.

[0011] 3. The compressed air source of this solution is atmospheric air, which is inexhaustible and does not require additional costs, effectively reducing the production cost of plate separation and improving production efficiency.

[0012] Preferably, as an improvement, the number of the cylinder is at least one, and the two gas ports of different cylinders have the same connecting points on the main pipeline.

[0013] Technical effect: This scheme adopts the above-mentioned setting, which is convenient for making full use of the abundant power of the punch press, and can also speed up the filling speed of compressed air to prepare for the continuous demand for refined and vulgar air.

[0014] Preferably, as an improvement, the switch valve assembly includes a pressure regulating valve and a solenoid valve arranged on the main pipeline in sequence along the airflow direction.

[0015] Technical effect: This solution adopts the above settings. The pressure regulating valve adjusts and stabilizes the pressure of the output gas to the required working pressure, ensuring that the downstream equipment (such as nozzles) is supplied with compressed air at a constant pressure; while the solenoid valve realizes the rapid opening or closing of the gas channel through electromagnetic control, realizing remote or program control of the control gas. This solution is convenient to meet the different compressed air pressure requirements of plate stacks of different thicknesses by combining the pressure regulating valve and the solenoid valve.

[0016] Preferably, as an improvement, a first pressure gauge is further provided between the pressure regulating valve and the solenoid valve, and the pressure gauge is connected to the main pipeline through a first branch pipeline.

[0017] Technical effect: This scheme adopts the above-mentioned setting, which is convenient for real-time monitoring of the pressure value of the compressed air in the main pipeline behind the pressure regulating valve, to prevent it from being too high or too low and affecting the stable supply of compressed air to the stacked plates by the nozzle, so as to facilitate the stable separation of the plates and achieve the purpose of taking one plate at a time.

[0018] Preferably, as an improvement, a safety valve is further provided between the gas storage tank and the pressure regulating valve, and the safety valve is connected to the main pipeline through a second branch pipeline.

[0019] Technical effect: This scheme adopts the above settings. When the system pressure exceeds the preset safety value, the safety valve will automatically open to exhaust, preventing equipment damage or safety accidents caused by excessive pressure, and effectively ensuring construction safety.

[0020] Preferably, as an improvement, the safety valve is provided with a second pressure gauge corresponding to the safety valve, and the pressure gauge is connected to the main pipeline through a third branch pipeline.

[0021] Technical effect: This scheme adopts the above-mentioned setting, which is convenient for real-time monitoring of the air pressure value in the gas tank, effectively ensuring that the pressure in the gas tank is within the rated pressure range of the gas tank, and protecting the safe operation of the gas tank.

[0022] Preferably, as an improvement, the inlet ends of the second pipeline and the third pipeline are connected to the same point of the main pipeline.

[0023] Technical effect: This scheme adopts the above-mentioned setting, which is convenient for real-time monitoring of the pressure values ​​of the gas tank outlet, safety valve inlet and regulating valve inlet.

[0024] Preferably, as an improvement, both the first pipeline and the third pipeline are provided with stop valves.

[0025] Technical effect: This scheme adopts the above-mentioned setting to cut off or connect the flow in the gas pressure gauge, which is convenient for quickly shutting off the gas supply in system maintenance, overhaul or emergency situations, and can also protect the pressure gauge. For example, when the separation device of this scheme is not running, the gas pressure is too high or it is under overhaul, the pressure gauge can be protected by closing the stop valve to avoid damage to the pressure gauge due to sudden high gas pressure.

[0026] Preferably, as an improvement, the inlet end of the main pipeline is connected to a filter.

[0027] Technical effect: This solution adopts the above-mentioned setting to improve the safety of compressed air and prevent air impurities from rushing towards the plate through the separation device and affecting the surface of the plate.

[0028] Preferably, as an improvement, the nozzle outside the safety valve is connected to an air jet pipe, and the outlet end of the air jet pipe faces the other side surface of the plate.

[0029] Technical effect: This scheme adopts the above-mentioned setting to further improve the utilization rate of compressed air in the gas tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is further described in detail through specific implementation methods:

[0034] The figure marks in the drawings of the specification include: filter 1, cylinder 2, first pressure gauge 31, second pressure gauge 32, safety valve 4, pressure regulating valve 5, stop valve 6, solenoid valve 7, nozzle 8, air storage tank 9, one-way valve 10, main pipeline 11, plate 12, oil film 13, vacuum chamber 14, and jet pipe 15.

[0035] Example 1

[0036] This solution provides a plate separation device, such as the attached Figure 1 and attached Figure 2 As shown, it includes a main pipeline 11 and a cylinder 2, a gas storage tank 9, a switch valve assembly and a nozzle 8 which are connected to the main pipeline 11 in sequence along the gas flow direction. The air inlet end of the main pipeline 11 is connected to the atmosphere, and the inlet end of the main pipeline 11 is connected to a filter 1, so as to improve the safety of compressed air and prevent the compressed air obtained by air impurities from passing through the separation device and rushing to the plate and affecting the surface of the plate.

[0037] The two air ports of the cylinder 2 are connected to the main pipeline 11 respectively. The piston rod of the cylinder 2 is fixedly connected to the punch press. The movement direction of the piston rod is consistent with the lifting direction of the punch press. The other end of the cylinder 2 away from the piston rod is fixed on the frame, so that the piston rod in the cylinder 2 can regularly discharge air into the gas tank 9 as the punch press moves up and down, thereby forming compressed air. There is at least one cylinder 2, and the two air ports of different cylinders 2 are connected at the same position on the main pipeline 11. A one-way valve 10 is provided on the main pipeline 11 between the two air ports and on the main pipeline 11 between the cylinder 2 and the gas tank 9, so as to facilitate the "one-way" transportation of purified air on the main pipeline 11 and accelerate the formation of compressed air in the gas tank 9.

[0038] The switch valve assembly includes a pressure regulating valve 5 and a solenoid valve 7 arranged on the main pipeline 11 in sequence along the air flow direction. A first pressure gauge 31 is also provided between the pressure regulating valve 5 and the solenoid valve 7, and the pressure gauge is connected to the main pipeline 11 through a first branch pipeline (not shown in the figure). A safety valve 4 is also provided between the gas storage tank 9 and the pressure regulating valve 5, and the safety valve 4 is connected to the main pipeline 11 through a second branch pipeline (not shown in the figure). A second pressure gauge 32 is correspondingly provided to the safety valve 4, and the pressure gauge is connected to the main pipeline 11 through a third branch pipeline (not shown in the figure). As a reference, the inlet ends of the second branch pipeline and the third branch pipeline are connected to the same point of the main pipeline 11. Stop valves 6 are provided on the first branch pipeline and the third branch pipeline where the pressure gauge is located to protect the pressure gauge.

[0039] The outlet of the nozzle 8 faces the side of the plate 12 .

[0040] In this scheme, the cylinder 2 moves up and down with the punch press. When the cylinder 2 rises with the punch press, the pressure in the two chambers in the cylinder 2 changes. Specifically, the pressure in the upper chamber increases, the air is discharged, and the pressure in the lower chamber decreases. The air discharged from the upper chamber flows along the main pipe 11 and is sucked into the lower chamber; when the cylinder 2 descends with the punch press, the pressure in the lower chamber increases, and the air is discharged. Because a one-way valve 10 is provided on the main pipe 11 between the two air ports of the cylinder 2, the air discharged from the lower chamber can only be compressed through the main pipe 11 between the cylinder 2 and the gas tank 9; when the pressure in the upper chamber decreases, air is sucked from the atmosphere through the main pipe 11. Whenever the cylinder 2 completes a "rise-fall" cycle with the punch press, the gas tank 9 can be inflated once. In this cycle, the compressed storage of air in the gas tank 9 can be realized.

[0041] When the compressed air in the gas tank 9 is needed, it is only necessary to open the switch valve assembly, namely the pressure regulating valve 5 and the solenoid valve 7. Specifically, the pressure regulating valve 5 is first adjusted according to the pressure value of the second pressure gauge 32 so that the compressed air outlet meets the spray pressure requirements of the plate; the opening and closing cycle of the solenoid valve 7 is set according to the plate sampling cycle, which effectively realizes the separation of the plate while saving the use of compressed air and improving the efficiency of compressed air use. Subsequently, the compressed air in the gas tank 9 is sprayed out from the nozzle 8, and the nozzle 8 is facing the side of the plate 12, so that the compressed air enters between the adjacent plates 12, destroying the oil film vacuum cavity between the plates 12, which is convenient for realizing the need to take a plate at a time.

[0042] During the process, if the second pressure gauge 32 detects that the air pressure in the gas storage tank 9 exceeds the preset safety pressure value on the safety valve 4, the safety valve 4 can release part of the compressed air from the branch pipeline, effectively protecting the pressure in the gas storage tank 9 within the safety value and avoiding safety hazards caused by excessive compressed air.

[0043] Example 2

[0044] In order to further improve the utilization rate of compressed air in the air storage tank 9, the difference between this embodiment and embodiment 1 is that Figure 3 As shown, the nozzle 8 outside the safety valve 4 is connected to an air injection pipe 15, and the outlet end of the air injection pipe 15 faces the other side of the plate.

[0045] In this embodiment, the compressed air released from the safety valve 4 is guided to the other side of the plate 12 through the jet pipe 15 , so as to further assist in achieving the separation of the plate 12 by the jet pressure of the compressed air.

[0046] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
