[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-6The utility model provides a technical solution for a heavy-duty rear gauge assembly for a bending machine: a heavy-duty rear gauge assembly for a bending machine, comprising a bending machine 1 and two cross beams 11 symmetrically arranged at the bottom end of the rear side of the bending machine 1, a feeding rack 2 is arranged at the lower end of the front side of the bending machine 1, and also includes a longitudinal adjustment mechanism 6 symmetrically mounted on the two cross beams 11, the longitudinal adjustment mechanism 6 includes a fixed seat 62 and a base 61 connected at the two ends of the bottom of the fixed seat 62 corresponding to the two cross beams 11, the inner middle part of the longitudinal adjustment mechanism 6 is rotatably connected to the longitudinal adjustment screw 63, and the interior of the longitudinal adjustment mechanism 6 is symmetrically installed on both sides of the longitudinal adjustment screw 63. A longitudinal sliding rail 64 is symmetrically installed on the two longitudinal sliding rails 64, and a longitudinal movable seat is slidably connected to the two longitudinal slide rails 64. 65, an internal threaded hole is provided in the middle of the longitudinal movable seat 65, and the longitudinal movable seat 65 is threadedly connected to the longitudinal adjustment screw 63 through the internal threaded hole; when working, when the driving mechanism drives the driven pulley 66 to rotate, the driven pulley 66 will drive the longitudinal adjustment screw 63 to rotate. Since it is threadedly connected to the longitudinal movable seat 65, when the longitudinal adjustment screw 63 rotates, the longitudinal movable seat 65 will move linearly along its surface, and when moving, the longitudinal slide rail 64 can ensure the stability of the longitudinal movable seat 65 when moving. The longitudinal movable seat 65 is used to drive the transverse fixed seat 5 and the vertical adjustment mechanism 4 to move longitudinally in a linear manner, so as to adjust the front and rear direction of the rear finger 3 on the bending machine (i.e., longitudinal direction, which can be referred to Figure 1 and Figure 2 The position of the bending machine can be adjusted to suit the positioning of different materials during bending.

[0038] One end of the longitudinal adjustment screw 63 passes through the fixed seat 62 and extends to its front end surface, which is fixedly connected to a driven pulley 66. The two longitudinal adjustment mechanisms 6 are connected by a power mechanism transmission. The power mechanism includes a fixed plate 7 installed at the bottom front end of one of the longitudinal adjustment mechanisms 6. The rear side surface of the fixed plate 7 is vertically installed with a driving motor 71. The front side bottom of the fixed plate 7 is rotatably provided with a main pulley 72. The output end of the driving motor 71 passes through the fixed plate 7 and is connected to the main pulley 72. When it is necessary to adjust the longitudinal position of the rear finger 3, the control box on the bending machine is used to control the driving motor 71 to work, and the driving motor 71 drives the main pulley 72 to rotate. The main pulley 72 synchronously drives the driven pulleys 66 on the front sides of the two longitudinal adjustment mechanisms 6 to rotate synchronously through the transmission belt 75. In this way, the longitudinal movable seats 65 on the two longitudinal adjustment mechanisms 6 are synchronously moved longitudinally, thereby adjusting the longitudinal position of the rear finger 3.

[0039] like Figure 7 and 8As shown, two tension-adjusting wheels 73 are further provided at the upper front end of the fixing plate 7, and a plurality of adjustment positioning holes 74 are provided at the front side surface of the fixing plate 7 below the two tension-adjusting wheels 73. A transmission belt 75 is commonly connected to the driven pulleys 66 at the front ends of the two longitudinal adjustment mechanisms 6 and the main pulley 72. One end of the transmission belt 75 is sleeved on the two driven pulleys 66, and the other end passes around the two tension-adjusting wheels 73 and is sleeved on the main pulley 72. By installing the tension-adjusting wheels 73 in the adjustment positioning holes 74 at different positions, the tensioning of the transmission belt 75 can be adjusted, so that the power mechanism can better drive the two longitudinal adjustment mechanisms 6 to work synchronously.

[0040] like Figure 5 and 6 As shown, the two longitudinal adjustment mechanisms 6 are commonly connected to a transverse fixing seat 5, and two transverse slide rails 51 are symmetrically installed on the upper surface of the transverse fixing seat 5. The transverse fixing seat 5 and the transverse slide rail 51 and the positioning screw hole 52 cooperate with the transverse adjustment seat 41 to form a transverse adjustment mechanism for adjusting the transverse position of the rear gear finger 3. Two groups of positioning holes are opened on the surface of the transverse adjustment seat 41 near the two vertical slide bars 42, and each group of positioning holes is provided with two, and respectively correspond to the positioning screw holes 52 on the two transverse slide rails 51; the transverse adjustment seat 41 slides on the two transverse slide rails 51 The lateral adjustment seat 41 can be screwed into the positioning screw hole 52 through the bolt through the positioning hole to be fixed to the lateral slide rail 51. By moving and adjusting the lateral adjustment seat 41 on the lateral slide rail 51, not only the lateral position of the rear finger 3 can be adjusted, but also the distance between the two rear fingers 3 can be adjusted, so that it can adapt to the bending positioning of materials of different widths. After the adjustment is completed, the lateral adjustment seat 41 can be fixed to the lateral slide rail 51 by passing the screw through the positioning hole and then screwing it into the positioning screw hole 52, so that the adjusted position of the rear finger 3 can be positioned.

[0041] like Figure 9 As shown, each vertical adjustment mechanism 4 is connected to a rear finger 3, and the height adjustment seat 45 is provided with a protrusion at one end corresponding to the rear finger 3, and a groove is provided at one end of the rear finger 3 corresponding to the protrusion. The protrusion at one end of the height adjustment seat 45 is inserted into the groove and fixed by bolts. The rear finger 3 and the height adjustment seat 45 can be connected and fixed by bolts, and the purpose of designing the protrusion and the groove is that after the bolts are released, the angle between the rear finger 3 and the height adjustment seat 45 can be adjusted. After the angle adjustment is completed, the two can be fixed with bolts.

[0042] like Figure 9As shown, the horizontal slide rail 51 is provided with a plurality of vertical adjustment mechanisms 4 that can slide on its surface. The vertical adjustment mechanism 4 includes a horizontal adjustment seat 41 slidably arranged on the two horizontal slide rails 51. Two vertical slide rods 42 are symmetrically installed on the upper surface of the horizontal adjustment seat 41. The tops of the two vertical slide rods 42 are commonly connected with a top seat 43, and the two vertical slide rods 42 are also commonly slidably connected with a height adjustment seat 45 between the top seat 43 and the horizontal adjustment seat 41. A height adjustment screw 44 is provided through the middle of the top seat 43. The height adjustment screw 44 is rotatably connected to the top seat 43. A cylindrical lifting block is installed on the lower end surface of the height adjustment seat 45 corresponding to the height adjustment screw 44, and a threaded hole is opened through the surface of the lifting block. The surface of the height adjustment seat 45 is opposite to the height adjustment screw 44. A through hole is provided at the threaded hole for convenient passage of the height adjustment screw 44. One end of the height adjustment screw 44 is screwed into the threaded hole on the surface of the lifting block after passing through the through hole. A knob is connected to the top of the height adjustment screw 44. By turning the knob, the height adjustment screw 44 is driven to rotate on the top seat 43. When the height adjustment screw 44 rotates, the lifting block is connected to the lifting block and the threaded connection with it. The lifting block will connect to the height adjustment seat 45 and move linearly (i.e., up and down) along the surface of the height adjustment screw 44. Moreover, during the movement, the vertical slide bar 42 is limited to improve its stability when moving up and down. Therefore, the height adjustment seat 45 can be used to drive the rear finger 3 to adjust the height position, so as to adapt to the bending and positioning of materials of different heights.

[0043] The working principle of the utility model is: before working, the position of the rear stop finger 3 is adjusted according to the size of the material, and the specific adjustment is as follows:

[0044] Horizontal position adjustment: According to the width of the bending material, the multiple rear fingers 3 are moved on the horizontal adjustment mechanism using the vertical adjustment mechanism 4 so that the spacing between the multiple rear fingers 3 can be adapted to the width of the bending material, and the spacing between every two rear fingers 3 must also be adjusted to a suitable position. After the horizontal position adjustment of the rear fingers 3 is completed, the vertical adjustment mechanism 4 is fixed to the horizontal slide rail 51 with bolts;

[0045] Longitudinal position adjustment: The driven pulleys 66 on the front sides of the two longitudinal adjustment mechanisms 6 are driven by the power mechanism to rotate synchronously, thereby realizing the synchronous longitudinal movement of the longitudinal movable seats 65 on the two longitudinal adjustment mechanisms 6, thereby adjusting the longitudinal position of the rear gear finger 3. Before the adjustment, the tension of the transmission belt 75 of the power mechanism can also be adjusted to ensure the stability of the transmission effect.

[0046] Height adjustment: When the height of the rear finger 3 needs to be adjusted, the height adjustment screw 44 can be rotated by turning the knob. When the height adjustment screw 44 rotates, the lifting block drives the height adjustment seat 45 to move up and down along the surface of the height adjustment screw 44, thereby driving the rear finger 3 to adjust its height position, so as to adapt to the bending positioning of materials of different heights;

[0047] This design integrates horizontal, vertical and height adjustments, which can ensure that the rear finger 3 can adjust its position arbitrarily when bending and positioning materials of different sizes, so as to better adapt to the bending positioning of the material and ensure the bending efficiency of the material.

[0048] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
