Description

Technical Field

[0001] The utility model relates to the field of profile cutting, in particular to a clamping assembly for a tail - free profile cutting device. Background Technique

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] Aluminum alloy doors and windows processing, non - standard automation factories, etc. often use aluminum profiles. For the above two situations of using aluminum profiles, most of them are customized according to the needs of users for the length of aluminum profiles. Therefore, it is necessary to divide the length of the whole aluminum profile. When dividing the length of the whole profile, it is necessary to divide the cutting length of the whole profile into segments. However, during the process of dividing the length, it is inevitable to cause the remaining profile, thus generating tailings. The remaining tailings are difficult to be reused, which leads to the waste of profiles.

[0004] For the existing profile cutting device, first, the profile is placed on the cutting table, and then continuously fed through the clamping device. During the process of clamping and feeding the profile, since there must be more than two clamping devices, due to the distance between the two clamping devices for clamping the profile, the cutting positions of the length to be cut and the remaining length of the profile will be clamped by the clamping device, resulting in the inability to cut this part of the profile to form tailings. When cutting the profile, it is necessary to ensure the stability of the profile during the clamping process to prevent the profile from shaking during cutting, which affects the cross - section of the profile. Especially during the synchronous cutting of multiple profiles, it is necessary to ensure that the profiles are on the same horizontal plane and that one end of the cutting direction of the profiles is flush to ensure the accuracy of synchronous cutting of multiple profiles. When the existing profile cutting device clamps the profile, many can only clamp a single profile, and for the row of profiles composed of multiple profiles, it cannot clamp or has a poor clamping effect, and cannot adjust the clamping effect according to the number of profiles. When clamping multiple profiles, the clamping force is too large, resulting in friction between the profiles, and scratches on the surface of the profiles, affecting the quality of the profiles. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a clamping assembly for a tail - free profile cutting device, which is used for clamping and feeding single or multiple profiles. The clamping cylinder that clamps the side of the profile can adjust its position according to the number of profiles to be cut, so as to switch between single - root or multiple - root profiles. Through the conversion of clamping the profile after the displacement of the first clamping assembly and the third clamping assembly, the remaining tailings can be cut, reducing the remaining tailings, thus avoiding the waste of profiles.

[0019] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0020] The clamping component of the present utility model is for a tail-free profile cutting device. The clamping component is arranged on the frame body 1 and includes a first clamping component 2 slidably arranged on the frame body 1, a second clamping component 3 arranged on the frame body 1, and a third clamping component 4 slidably arranged on the frame body 1;

[0021] Before describing each clamping component, the profile cutting mechanism will be described first. The saw blade of the cutting mechanism is located between the second clamping component 3 and the third clamping component 4, and taking the second clamping component 3 as a reference, the displacement direction of the saw blade of the cutting mechanism is perpendicular to the sliding displacement directions of the first clamping component 2 and the third clamping component 4.

[0022] The relationship among the first clamping component 2, the second clamping component 3, and the third clamping component 4 is that the first clamping component 2 and the third clamping component 4 slide on the frame body 1 through a slide rail, and the second clamping component 3 is fixedly arranged on the frame body 1. As shown in the attached drawings of the specification Figures 1-5 shown, the second clamping component 3 is a pressing member and includes a vertical plate 5, side plates 6 arranged on the opposite sides of the vertical plate 5, a top plate 7, a compression cylinder 8 arranged on the top plate 7, a compression plate 9 connected to the compression cylinder 8, and a guiding rod. The top plate 7 connects the vertical plate 5 with the side. The side plate 6 is used to place the profile against the edge for alignment and calibration; in order to prevent scratches on the surface of the profile after being pressed by the compression cylinder 8, a rubber pad is provided at the front end of the compression plate 9. The compression plate 9 is driven by the compression cylinder 8 to displace along the guiding rod, thereby clamping and limiting the profile.

[0023] The first clamping assembly 2 includes a base plate 10, a first displacement driving member 11 connected to the base plate 10, two sets of clamping members arranged on the base plate 10, and a lifting guide member 12 arranged below the base plate 10; the first displacement driving member 11 is a motor-driven lead screw displacement, and the sliding block of the first displacement driving member 11 is connected to the base plate 10, and the clamping member is driven to move along the x-axis through the first displacement driving member 11.

[0024] The lifting guide 12 includes a connecting plate, a guide shaft connected to the base plate 10 at one end and the connecting plate at the other end, a cylinder arranged on the connecting plate, and a guide roller connected to the cylinder head piston rod; for the lifting guide 12, the cylinder stroke of the lifting guide 12 is relatively short, and its main function is to drive the guide rod to move through the cylinder when placing the profile, so as to prevent friction between the profile and the base plate 10, which may cause scratches on the profile.

[0025] The main function of the clamping member is to limit the y-axis direction of the profile. In order to make the clamping member applicable to clamping and limiting single and multiple profiles, it is necessary to adjust the clamping cylinder 14 of the clamping member. The top plate 7 of the pressing member is provided with a clamping member, and the clamping member is arranged in a direction opposite to the feeding direction. The clamping member includes a slide rail, a dislocation plate 13 arranged on the slide block of the slide rail, a clamping cylinder 14 arranged on the dislocation plate 13, and a locking bolt.

[0026] The position distance of the offset plate 13 on the slide rail is controlled by the locking bolt, thereby controlling the distance between the clamping cylinder 14 and the profile. In order to enable the clamping cylinder 14 to clamp more profiles, the distance between the offset plate 13 and the slide rail connection end and the offset plate 13 and the cylinder connection section are staggered, so that the clamping cylinder 14 can limit more profiles.

[0027] The third clamping component 4 is arranged on the sliding block of the second displacement driving member 19, and a transverse plate 15 is provided between the third clamping component 4 and the sliding block. The second displacement driving member 19 is a motor connected to a screw rod to drive the slider to move back and forth on the screw rod. The third clamping component 4 includes a clamping member and a clamping member arranged on the transverse plate 15. For the third clamping component 4, it is composed of a clamping member and a clamping member, but the difference from the first clamping component 2 is that the setting direction of the clamping member is consistent with the feeding direction. Because if it is the same as the direction of the first clamping component 2, it will affect the gap between the third clamping component 4 and the second clamping component 3, thereby affecting the clamping effect and stability of the profile.

[0028] As shown in the attached figure of the instruction manual Figure 6As shown, the function of the clamping and supporting member is equivalent to the combination of the lifting guide member 12 and the clamping member in the first clamping assembly 2. The clamping and supporting member includes a mounting plate 16, a lifting cylinder 17 provided on the mounting plate 16, a fixing plate connected to the piston rod of the lifting cylinder 17, a slide rail provided on the fixing plate, a clamping cylinder 18 provided on the slide rail, a locking bolt provided on the slide rail, and a guide roller. By driving the guide roller and the clamping cylinder 18 on the fixing plate through the lifting cylinder 17, when the first clamping assembly 2 approaches the second clamping assembly 3, the lifting cylinder 17 can be used to control the downward displacement of the guide roller and the clamping cylinder 18, so as to make way for the moving position of the second clamping assembly 3. When the first clamping assembly 2 moves away from the second clamping assembly 3, the lifting cylinder 17 drives the guide roller and the clamping cylinder 18 to rise, avoiding friction with the profile during the feeding process due to the excessive length of the profile.

[0029] Regarding how to reduce the remaining tail material and achieve no tail material through the clamping assembly, the specific method is as follows: During the initial feeding, the first clamping assembly 2 is used for clamping and feeding. When the difference between the remaining length of the profile in the first clamping assembly 2 and the length to be cut exceeds the minimum distance between the first clamping assembly 2 and the second clamping assembly 3, the profile is conveyed from the first clamping assembly 2 to the third clamping assembly 4 for clamping. Then, the third clamping assembly 4 is driven to move by the second displacement driving member 19 until the clamping distance of the second clamping assembly 3 is equal to the difference between the remaining length of the profile and the length to be cut minus the thickness of the saw blade. Then, the end of the profile is clamped by the second clamping assembly 3, and the profile is cut by the saw blade.

[0030] Because when the difference between the remaining length of the profile and the length to be cut exceeds the minimum distance between the first clamping assembly 2 and the second clamping assembly 3, it will exceed the displacement stroke of the first clamping assembly 2, resulting in the remaining part being unable to be clamped and fed by the first clamping assembly 2, and thus the remaining profile cannot be cut. Therefore, through improvement, after the profile is conveyed to the maximum displacement stroke of the first clamping assembly 2, it is clamped by the third clamping assembly 4. Then, the third clamping assembly 4 is driven to move by the second displacement driving member 19, so that the sum of the displacement distances of the first clamping assembly 2 and the third clamping assembly 4 plus the thickness of the saw blade is equal to the length of the profile to be cut. By adding the two displacements, the length of the profile to be cut can be obtained. After cutting the part clamped by the second clamping assembly 3, the target value of the profile can be obtained. Since changing the clamping direction of the profile will include the thickness of the saw blade in the calculation and affect the profile accuracy, the value of the saw blade thickness also needs to be subtracted. Finally, the cutting length of the target profile is obtained, thus saving the remaining tail material of the profile and further improving the utilization rate of the profile.

[0031] In summary, the present application is used for clamping and loading single or multiple profiles. The clamping cylinder 18 that clamps the side of the profile can adjust its position according to the number of profiles to be cut, so as to switch between single or multiple profiles. By converting the clamping of the profile after the displacement of the first clamping assembly 2 and the third clamping assembly 4, the remaining tail material can be cut, reducing the remaining tail material, thereby avoiding waste of profiles.
