Description

Technical Field

[0001] The utility model relates to the technical field of aluminum material stretching, in particular to a clamping device of an aluminum material stretching machine. Background Art

[0002] Aluminum is a widely used material made of aluminum and other alloy elements. It is currently widely used in various fields (such as construction).

[0003] Nowadays, aluminum is mainly produced by heating and extruding into strips. However, since the extruded aluminum strips will be partially bent, companies usually install corresponding stretching devices to stretch the aluminum to achieve the purpose of correction.

[0004] A stretching machine (such as an aluminum extrusion stretching device disclosed in the authorization announcement number CN219985816U) generally clamps the aluminum material by a clamp (clamping device) and separates the clamps from each other to achieve the purpose of stretching. However, in order to ensure the stability of the clamp movement, a slide rail is generally used, that is, the clamp device is arranged on the slide rail, and the clamp moves on the slide rail to improve stability. However, due to the frequent movement of the clamp on the slide rail, a large amount of heat is generated, and the existing stretching machine does not take effective measures to dissipate the heat of the slide rail. Therefore, the service life of the slide rail is generally not high.

[0005] In addition, during the stretching process, the aluminum material deforms and impurities on the surface of the aluminum material fall off. When the impurities fall on the slide rail, the clamp will not move smoothly and will also cause wear on the clamp and the slide rail.

[0006] In summary, necessary improvements need to be made to the above defects. Utility Model Content

[0079] At least two clamping devices 3 are slidably disposed on the slide rail 10;

[0080] The driving device is used to control the clamping devices to move closer or farther away from each other. In this embodiment, the slide rail 10 includes:

[0081] The rail body 100 is arranged on the frame 11;

[0082] The mounting platform 101 is arranged on the frame 11;

[0083] The rail body 100 and the mounting platform 101 are integrally formed, and a heat dissipation cavity is formed inside. The driving device is composed of at least an air source and a driving body 20 disposed on each mounting platform 101. The driving body 20 has a driving end and a driving cavity for controlling the driving end.

[0084] The driving cavity is connected to the air source through the heat dissipation cavity;

[0085] When the driving cavity is supplied with air by the air source, the driving end controls the clamping device 3 to separate and stretch the aluminum material, and at the same time uses the heat dissipation cavity to dissipate heat for the slide rail 10.

[0086] In this embodiment, the heat dissipation cavity includes:

[0087] Air intake cavity;

[0088] A first cavity 41;

[0089] A second cavity 42;

[0090] Among them, a control valve is provided at the connection between the air inlet chamber, the first chamber 41 and the second chamber 42, and the control valve has at least one inlet connected to the air inlet chamber and two outlets 4a connected to the first chamber 41 and the second chamber 42 respectively, that is, the valve core 4b of the control valve can control the connection between the inlet and any outlet 4a when it is active.

[0091] The first cavity 41 and the second cavity 42 are respectively communicated with the driving cavities of the driving bodies.

[0092] In this embodiment, the driving body 20 includes:

[0093] The body 200 is fixed on the mounting platform 101 and has a driving cavity;

[0094] The driving plate 201 moves in the driving cavity and divides the driving cavity into an air cavity 200a and a reset cavity 200b;

[0095] A driving shaft 202 is connected to the driving plate 201, and one end of the driving shaft passes through the driving plate 201 and is connected to the clamping device 3;

[0096] A one-way air inlet nozzle 203 (one-way valve), which is disposed on the body 200 and communicates with the air cavity 200a;

[0099] The air cavity 200a is connected to the heat dissipation cavity (the first cavity or the second cavity) through a one-way air inlet valve 203.

[0100] In this embodiment, the rail body 100 is provided with an air nozzle connector 100 a , that is, the air pump can be connected to the air nozzle connector 100 a through a pipe, so as to communicate with the air inlet cavity.

[0101] refer to Figure 1-4 The stretching principle of this embodiment is to fix the two ends of the aluminum material on the clamping device and supply air to the air inlet cavity through an air pump. The air flow is regulated by the control valve and enters the air cavity of the driving body of the mounting table through the first cavity or the second cavity. When the air pressure in the air cavity increases, the driving plate is controlled to move, and the clamping devices are driven to separate from each other through the driving shaft, thereby realizing the stretching of the aluminum material.

[0102] In this embodiment, when the clamping device moves, air will flow in the first cavity or the second cavity corresponding thereto, so the flowing air can be used to dissipate heat for the slide rail, thereby ensuring the service life of the slide rail.

[0103] After the stretching is completed and the aluminum material is removed, when the clamping device needs to be reset, the exhaust valve is opened to exhaust the gas in the air cavity, and the driving plate can be controlled to move by the reset spring and drive the clamping device to reset.

[0104] Embodiment 2 is different from Embodiment 1 in that

[0115] In this embodiment: the first clamping plate 51 and the second clamping plate 52 are respectively provided with anti-skid pads 57 (to improve the anti-skid effect when clamping aluminum materials).

[0116] In this embodiment: the slide seat 30 is provided with an air injection structure 6 forming the air injection end, and the air injection structure 6 includes:

[0117] The jet chamber 60 is formed in the slide seat 30 and communicates with the drive chamber (exhaust valve 204) through the air pipe 61;

[0118] The nozzle 62 is mounted on the slide 30 and has a nozzle cavity 62a connected to the nozzle cavity 60;

[0119] The nozzle is composed of a first opening 631 and a second opening 632 which are spaced apart on the nozzle head 62 and communicate with the spray chamber 62a;

[0120] The piston shaft 64 is installed in the spray chamber 62a through the first spring 65 and can open or close the first opening 631 when moving;

[0121] An electromagnetic component communicating with the spray chamber 62 a and the second opening 632 is formed in the piston shaft 64 .

[0122] In this embodiment: the electromagnetic component includes:

[0123] An electromagnetic chamber 70 is formed in the piston shaft 64 and contains an electromagnet 71;

[0124] The electromagnetic shaft 72 is connected to the electromagnetic cavity 70 (the two ends of the electromagnetic spring 73 are respectively connected to the electromagnet 71 and the electromagnetic shaft 72) through the electromagnetic spring 73 (the stiffness coefficient is higher than that of the first spring);

[0125] The communication port is composed of a first communication port 741 and a second communication port 742 formed on the piston shaft 64;

[0126] A rubber plug 75 is installed on the electromagnetic shaft 72 and is used to close the first communication port 741;

[0127] The first communication port 741 and the second communication port 742 are in communication with the electromagnetic chamber 70 , and the second communication port 742 corresponds to the second opening 632 .

[0128] In this embodiment, the diameter of the first opening 631 is smaller than the diameter of the second opening 632 .

[0129] In this embodiment, a cooling chamber 80 is formed in the driving shaft 202 , and a coolant 81 is provided in the cooling chamber. A liquid replacement valve 82 is provided on the driving shaft 202 for replacing the coolant 81 in the cooling chamber 80 .

[0130] In this embodiment, in order to ensure the smooth movement of the slide seat, an air jet structure is provided on the slide seat. When the slide seat moves, the air jet structure sprays air and cleans the slide rail to prevent foreign matter from affecting the movement of the slide rail. The principle is:

[0131] When the slide rails move away from each other, the exhaust valve opens, and the air pump supplies air from the heat dissipation cavity to the air cavity. The air cavity sends the gas into the jet cavity through the exhaust valve and the air pipe, and further sprays it out through the first opening or the second opening on the nozzle to clean the slide rails.

[0132] At the same time, since the gas in the air cavity absorbs the heat of the slide rail, a cooling cavity is set in the drive shaft. When the gas flows in the heat dissipation cavity and enters the air cavity after absorbing heat, the coolant in the drive shaft cools the gas in the air cavity and is sent into the jet cavity from the control valve, and then sprayed toward the slide rail by the jet structure. Therefore, when cleaning, the heat absorbed by the gas is avoided from being sent back to the slide rail.

[0133] refer to Figure 7 The jet structure of this embodiment can jet through the first opening or the second opening. Since the calibers of the two openings are different, the jet speeds are different when the air flow is the same. Therefore, the slide rail can be jetted to different degrees:

[0134] Under normal jetting, the electromagnet is energized and attracts the electromagnetic shaft, and the rubber plug opens the first connecting port, and the airflow in the jet cavity enters the electromagnetic cavity through the first connecting port, and is sprayed toward the slide rail through the second connecting port and the second opening;

[0135] To improve the cleaning effect, the present embodiment can select a mode with a higher jet speed, that is, jetting through the first opening. In this mode, the electromagnet is powered off. When the air pressure in the spray chamber rises, the piston shaft moves to the right and opens the first opening. At the same time, since the diameter of the first opening is small, it can be sprayed at a higher rate to improve the cleaning effect of the slide rail.

[0136] It is worth mentioning that when the clamping structure of this embodiment clamps the aluminum material, the first clamping plate and the second clamping plate can clamp the end of the aluminum material by cooperating with the fastening bolts and the fastening threaded holes. In order to clamp the aluminum material with a complete end, the clamping structure of this embodiment can be controlled to rotate so that the first clamping plate and the second clamping plate can better contact the end of the aluminum material to ensure the stability of the clamping. The cylinder and the motor arranged in the slide seat can control the lifting or rotation of the clamping structure during the stretching process of the aluminum material, so as to assist in the stretching of the aluminum material (for example, before stretching, when the aluminum material with bent ends is fixed, the height of the clamping structure on both sides and the inclination state of the clamping plates are different. After the stretching is completed, the horizontal heights of the two clamping structures should be the same, and the clamping plates should also be in a horizontal state. Therefore, the cylinder and the motor can be used to control the lifting of the mounting frame or the rotation of the clamping plate respectively to assist in the stretching of the aluminum material).

[0137] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
