Description

Technical Field

[0001] The present invention relates to the technical field of sheet straightening, and particularly to a fully automatic two-way straightening machine for strip-shaped workpieces. Background Art

[0002] During the production and processing of strip-shaped workpieces, due to various factors such as raw material characteristics and processing technology, strip-shaped workpieces often have varying degrees of bending deformation, resulting in non-compliance with the straightness requirements.

[0003] Traditional straightening methods mostly rely on manual operation or simple mechanical devices. Manual straightening is inefficient and difficult to guarantee accuracy, while simple mechanical devices often have a single function and cannot meet the straightening requirements of strip-shaped workpieces of different specifications. Moreover, during traditional straightening, if it is necessary to straighten the front and back sides of strip-shaped workpieces, repeated flipping is usually required. During the flipping process, the natural sag of the workpiece due to its own weight is extremely likely to cause additional adverse effects on the straightness of the workpiece, thereby reducing the straightening quality and increasing the scrap rate, making it difficult to meet the requirements of modern high-efficiency and high-precision industrial production. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned existing fully automatic two-way straightening machine for strip-shaped workpieces, the inventor hereby proposes a fully automatic two-way straightening machine for strip-shaped workpieces to solve such problems.

[0023] In the following description, many specific details are set forth in order to fully understand the present invention.

Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0024] Embodiment

[0025] Referring to Figures 1 to 4 , this is an embodiment of the present invention, including a fully automatic two-way straightening machine for strip-shaped workpieces, including a support unit, a pressing unit, and a control unit. The support unit includes a base 1, a main support component 5 and a secondary support component 10 symmetrically arranged above the base 1, and flipping components 7 respectively arranged at both ends of the base 1, and the main support component 5 is located between the flipping components 7 arranged at both ends of the base 1;

[0026] The pressing unit includes a displacement component 6 slidably mounted on the base 1, a pressure supply component 9 arranged at the top of the displacement component 6, a pressing component 4 arranged below the pressure supply component 9, and a straightening component 3 arranged below the pressing component 4, and the straightening component 3 is located directly above the main support component 5;

[0027] The pressing unit includes a displacement component 6 slidably mounted on the base 1, a pressure supply component 9 arranged at the top of the displacement component 6, a pressing component 4 arranged below the pressure supply component 9, and a straightening component 3 arranged below the pressing component 4;

[0028] The control unit includes multiple groups of measuring components 2 evenly distributed on the base 1, and a control terminal 8 arranged outside one end of the base 1;

[0029] During use, the base 1 serves as the main frame of the entire device, having sufficient strength and rigidity, and can provide stable support for the installation of other parts. The main support component 5 and the secondary support component 10 have the same structure, and both can slide horizontally along the base 1. At the same time, the tops of both contact and support the slat workpiece 11, and can provide an upward support force to offset the self-weight of the workpiece and keep the workpiece stable.

[0030] Among them, there are two groups of straightening components 3. The two groups of straightening components 3 are symmetrically arranged below the pressing component 4, and the two groups of straightening components 3 can perform sliding displacement in opposite directions below the pressing component 4.

[0031] Furthermore, both the support unit and the pressing unit are controlled by the control terminal 8. The measuring component 2 and the control terminal 8 are in data communication with each other, and both can achieve data transmission and reception.

[0032] Furthermore, a pressure sensor is arranged at the top of the measuring component 2. By sensing pressure and emitting and receiving signals, the height change of the workpiece surface is analyzed to determine the highest and lowest points of each bend, and the detection data is transmitted to the control terminal 8. The control terminal 8 can operate each component in the support unit and the pressing unit by receiving the data information transmitted by the measuring component 2, such as controlling the movement of the moving component 6, the downward pressure of the pressing component 4, the movement of the main support component 5 and the support component 10, and the telescoping of the hydraulic rods at their tops.

[0033] Furthermore, the pressing component 4 is a hydraulic cylinder, a pneumatic cylinder, an electric actuator, an electromagnet, or other devices that can provide pressure or driving force. When the pressing component 4 is a hydraulic cylinder, the position and the applied force of the straightening component 3 are adjusted by controlling the flow rate and pressure of the hydraulic oil. When the pressing component 4 is an electric actuator, the position and the applied force of the straightening component 3 are adjusted by controlling the rotation of the motor.

[0034] The main support component 5 and the secondary support component 10 have the same structure, and the tops of both are at the same horizontal height. The tops of both contact and support the slat workpiece 11, and can provide an upward support force to offset the self-weight of the workpiece and keep the workpiece stable.

[0035] During use, when straightening the slat workpiece 11, first, place the slat workpiece 11 to be straightened on the automatic straightening tooling. The two groups of flipping components 7 clamp both ends of it. Multiple groups of measuring components 2 comprehensively detect the straightness of the slat workpiece 11 by sensing pressure and emitting and receiving signals, analyze the high and low points of each bend, and transmit the detection data to the control terminal 8;

[0036] If the measuring component 2 detects that there is a positive straightness deviation exceeding the preset threshold in a certain local area of the workpiece, and this deviation reaches the maximum value in this area, that is, a bulge, (refer to Figure 3 ), the control terminal 8 calculates the adjustment distances of the lower main support component 5 and the secondary support component 10 according to the detection data, and then controls the main support component 5 and the secondary support component 10 to move to both sides of the maximum straightness value on the base 1, that is, the lowest point of the downward bending arc of the slat workpiece 11 to provide support (refer to Figure 3 ). At the same time, the control terminal 8 sets various parameters of the adjustment and straightening component 3 by calculation, adjusts its distance from the workpiece surface to a predetermined value, and prepares for applying pressure subsequently. Then, the control terminal 8 controls the displacement component 6 to slide horizontally along the base 1. The sliding displacement component 6 will drive the pressure application component 4 and the straightening component 3 to move in the direction facing the convex point. The pressure application component 4 is started. According to the preset straightening program, at this time, the two groups of straightening components 3 will perform relative movement along the lower part of the pressure application component 4, and finally the two groups of straightening components 3 will fit together to form a whole. At this time, the two groups of straightening components 3 that fit together are facing the convex point (refer to Figure 3 ). At this time, the pressure application component 4 will control the straightening component 3 to move downward and apply pressure to this convex point for straightening operation;

[0037] After straightening one convex point is completed, the control terminal 8 controls the displacement component 6 to move to the position of the next convex point to be straightened, and repeats the above operations to straighten each convex area in turn;

[0038] If the measuring component 2 detects that there is a negative straightness deviation exceeding the preset threshold in a certain local area of the workpiece, and this deviation reaches the minimum value in this area, that is, a depression, (refer to Figure 4 ), the control terminal 8 adjusts the position of the straightening component 3 to move it upward, increasing the distance from the workpiece surface to provide enough space below. At the same time, the control terminal 8 adjusts the main support component 5 and the secondary support component 10 to move on the base 1 so that the main support component 5 and the secondary support component 10 fit together, and the two that fit together move to the lowest point of the local straightness (refer to Figure 4 ) to support the workpiece. It is also possible to only control the main support component 5 to abut and support at the lowest point of the local straightness, while the control terminal 8 can control one or more idle secondary support components 10. The main function of these secondary support components 10 is to resist the gravity of the workpiece and prevent the workpiece from sagging naturally during the straightening process. Then, the control terminal 8 controls the displacement component 6 to move the pressure application component 4 to the direction facing this depression point, starts the pressure application component 4 for straightening operation, and the two groups of straightening components 3 slide outward synchronously. The two groups of straightening components 3 that separate outward are facing the minimum straightness value of the depression point (refer to Figure 4) Subsequently, the pressing component 4 drives the two groups of straightening components 3 to apply downward pressure on the sunken point to straighten the sunken point;

[0039] After straightening one sunken point, the control terminal 8 controls the displacement component 6 to move to the position of the next sunken point to be straightened, and repeats the above operations to straighten each sunken area in turn

[0040] When the straightening of one side and its opposite side of the strip-shaped workpiece is completed, the workpiece is flipped by the flipping components 7 at both ends, and then the above straightening steps are repeated to straighten the other two sides of the strip-shaped workpiece until the entire workpiece is straightened qualified. Finally, the straightened strip-shaped workpiece is removed from the automatic straightening tooling on the base 1, and subsequent processing or use can be carried out. Through the cooperation of the straightening component 3, the main support component 5 and the secondary support component 10, the upper and lower sides of the strip workpiece can be straightened without flipping, reducing the number of times of flipping the workpiece and significantly improving the flexibility of the device.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
