DETAILED DESCRIPTION

The output end of the first motor 6 is connected to the lead screw 5, and the lead screw 5 is driven to rotate by the first motor 6. The outer wall of the lead screw 5 is threadedly sleeved with a first movable seat 7, and the first movable seat 7 An indicator block 8 is fixedly installed on the front side wall. When the screw 5 rotates, it can drive the first movable seat 7 and the indicator block 8 to move synchronously. The indicator block 8 translates along the upper surface of the marking plate 3. The indicator block 8 moves to the marking line 4 at different positions on the upper surface of the marking plate 3 to realize the marking function. A connecting rod 9 is fixedly installed on the upper surface of the first movable seat 7. The rear side of the connecting rod 9 is connected to a limiting unit. The bottom end of the connecting rod 9 is connected to a stamping unit. The connecting rod 9 is driven to move by the first movable seat 7, and then the indicator block 8 and the stamping unit are driven to move synchronously, thereby realizing the linkage adjustment of the indicator block 8 and the stamping unit, so that the stamping position of the stamping unit can be adjusted by the indicator block 8.

1 and 3 , the limiting unit includes a mounting seat 15 fixedly mounted on the rear side of the upper surface of the workbench 1, a light rod 16 fixedly mounted on the front side of the mounting seat 15, a second movable seat 17 is provided with a sliding sleeve on the outer side of the light rod 16, a connecting seat 18 is fixedly mounted on the front side of the second movable seat 17, and baffles 19 are symmetrically mounted on the left and right sides of the connecting seat 18. When the second movable seat 17 is moved by force, it can move along the light rod 16 to limit the moving direction of the second movable seat 17, so as to ensure that the second movable seat 17 drives the connecting seat 18 and the baffle 19 to achieve synchronous translation; wherein, the upper surface of the connecting seat 18 is fixedly connected to the rear end of the connecting rod 9, thereby driving the connecting seat 18 to move synchronously through the movement of the connecting rod 9.

As shown in FIG3 , the stamping unit includes a connecting block 10 fixedly mounted on the outside of the connecting rod 9, a vertical rod 11 is vertically and fixedly mounted on the bottom end of the connecting block 10, a mounting plate 12 is fixedly mounted on the bottom end of the vertical rod 11, a cylinder 13 is mounted on the front side wall of the mounting plate 12, an output end of the cylinder 13 passes through the mounting plate 12 to the rear side and is connected to a punching head 14, the punching head 14 is driven to move to the rear side by the opened cylinder 13 to achieve bending processing of the profile; the punching head 14 corresponds to the center line position of the connecting seat 18, thereby ensuring that when the punching head 14 moves to the rear side, it can accurately act on the center of the connecting seat 18 to avoid misalignment of the two and failure to achieve stamping; the rear side wall of the punching head 14 is set to an arc shape, and the arc-shaped punching head 14 can stamp the profile more smoothly, prompting the profile to form an arc-shaped curvature at the bending point.

As shown in Figure 2, a screw 20 is provided on the inner wall of the shell 2 to rotate from left to right through a bearing, and symmetrical and opposite external threads are provided on the left and right sides of the screw 20. A second motor 21 is installed on the right side wall of the shell 2, and the output end of the second motor 21 is connected to the screw 20. The left and right sides of the outer wall of the screw 20 are symmetrical and threaded with two third movable seats 22, and the rear side walls of the two third movable seats 22 are fixedly installed with positioning plates 23 respectively, and a profile 25 is positioned between the two positioning plates 23. The screw 20 is driven to rotate by the turned-on second motor 21, so that the two third movable seats 22 on the outer wall of the screw 20 are synchronously moved toward the middle, and the two positioning plates 23 are synchronously moved toward the middle, so as to gradually position the side wall of the profile 25. At this time, the profile 25 is preliminarily positioned at the right-angle space formed by the positioning plate 23 and the baffle 24, and the positioned profile 25 corresponds to the position of the marking plate 3.

Referring to Figures 3 and 4, in order to ensure the stability of the profile 25 at the two positioning plates 23, baffles 24 are vertically installed on the opposite sides of the two positioning plates 23, and the baffles 24 and the positioning plates 23 form a right-angle space. The side walls of the profile 25 are placed in the right-angle space formed by the baffles 24 and the positioning plates 23, and the side walls of the profile 25 are placed in contact with the baffles 24. Under the clamping action of the two positioning plates 23, the profile 25 cooperates with the baffles 24 to perform preliminary positioning; in addition, in order to ensure that the profile 25 can move smoothly along the side walls of the positioning plates 23, rollers are provided at the side walls of the positioning plates 23. Through the rolling contact between the rollers and the side walls of the profile 25, while being able to meet the positioning requirements of the profile 25, it can promote the smooth movement of the profile 25 along the outer wall of the roller at the positioning plate 23, and promote the profile 25 to be more smoothly pushed to the baffle 19 for bending and stamping processing.

The marking plate 3 is equal to the length of the profile 25, and the marking plate 3 and the profile 25 are arranged parallel to each other front and back, and the center points of the marking plate 3, the profile 25 and the screw 20 are collinear, thereby ensuring that the profile 25 clamped by the two positioning plates 23 is collinear with the center point of the screw 20, and further ensuring that when the indicator block 8 moves to the first marking line 4 from left to right, the punch head 14 corresponds to one quarter of the profile 25, thereby realizing the bending processing at one quarter of the profile 25.

It is worth noting that the cylinder 13 used in the present application is a self-locking cylinder commonly used on the market, and its output end can stay at any position and be locked; the first motor 6 and the second motor 21 use self-locking motors commonly used on the market with output ends that can be locked. When they stop working, their output ends can self-lock and will not rotate under external force, and the first motor 6 and the second motor 21 are set as forward and reverse motors, and their output ends can rotate forward or reverse according to usage requirements; the above-mentioned existing components will not be described in detail here.

The number of marking lines 4 can be flexibly divided according to actual production needs. In this embodiment, three marking lines 4 are drawn on the outer wall of the marking plate 3 as an example. The marking plate 3 is divided into four equal parts by the three marking lines 4. When the indicator block 8 corresponds to the position of the first marking line 4 from left to right, one quarter of the profile 25 at this time corresponds to the stamping unit. When the indicator block 8 corresponds to the marking line 4 in the middle of the marking plate 3, the stamping head 14 performs bending processing on the middle part of the profile 25, thereby realizing flexible adjustment of the bending processing at different equal points of the profile 25.

The working principle of a profile bending and positioning mechanism in this embodiment is as follows:

Place the side wall of the profile 25 against the baffle 24, and drive the screw 20 to rotate by turning on the second motor 21, so that the two third moving seats 22 on the outer wall of the screw 20 move synchronously toward the middle, and the two positioning plates 23 move synchronously toward the middle, so as to gradually position the side wall of the profile 25. At this time, the profile 25 is initially positioned at the right angle space formed by the positioning plate 23 and the baffle 24, and the positioned profile 25 corresponds to the position of the marking plate 3;

The first motor 6 is turned on to drive the lead screw 5 to rotate, causing the first moving seat 7 to move along the outer wall of the lead screw 5 to adjust the position of the indicator block 8 relative to the marking plate 3. When the indicator block 8 moves, it can drive the connecting rod 9, the second moving seat 17, the connecting block 10, the vertical rod 11, and the punch head 14 to move together, so as to realize the synchronous translation of the connecting seat 18, the baffle 19, and the punch head 14; if it is necessary to bend the profile 25 at one quarter, the indicator block 8 is moved to the first marking line 4 from left to right and stopped. At this time, the punch head 14 corresponds to the profile 25 at one quarter, and the gas is turned on. The cylinder 13 drives the punch head 14 to move backward, and the punch head 14 drives the profile 25 to gradually move along the side wall of the positioning plate 23 to the baffle 19, and the bending process of the profile 25 at one quarter is realized under the joint action of the two baffles 19 and the punch head 14; when bending a batch of profiles 25, the profiles 25 are placed between the two positioning plates 23 in sequence according to the above steps, and the punching of the profile 25 at one quarter can be directly realized without adjusting the position of the punch head 14 relative to the profile 25 again, thereby realizing the stamping process of the profile 25 at one quarter in batches continuously without repeated measurement;

The utility model can perform selective bending processing at different equally divided points on the outer wall of the profile 25, and eliminates the steps of repeatedly measuring, marking, moving and the like the profile 25, reduces the preparation time for batch processing of the profile 25, and is more conducive to continuous bending processing of the profile 25.
