DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] See also Figure 1 - Figure 6 The present invention provides a technical solution for a high-efficiency bending and forming device for a metal support rod of a bar chair:
[0023] In an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , including a base 1 and a top plate 2, the inner wall of the top plate 2 is slidably connected with a pressure block 3, the inner wall of the pressure block 3 is slidably connected with a slider 4, one end of the slider 4 is installed with a pressure rod 5, and the top of the pressure rod 5 is installed with two first springs 6, the top of the base 1 is installed with a mounting plate 7, and the two sides of the mounting plate 7 are respectively slidably connected with two first connecting rods 8 and two second connecting rods 11, and the outer wall of one end of each first connecting rod 8 and the second connecting rod 11 is sleeved with a second spring 9 and a third spring 12, one end of the two first connecting rods 8 is fixedly connected with a first pressure plate 10, and one end of the two second connecting rods 11 is fixedly connected with a second pressure plate 13.
[0024] It should be noted that: before the equipment is started, the pressure block 3, the slider 4, and the pressure rod 5 are all in their respective starting positions, and the first spring 6, the second spring 9, and the third spring 12 are in an uncompressed state. By placing the metal rod on the first pressure plate 10 and the second pressure plate 13, the pressure block 3 is pressed down to drive the pressure rod 5 to move downward, and the bottom end of the pressure rod 5 contacts the metal rod and applies pressure. At the same time, the pressure block 3 is in sliding connection with the slider 4. During the downward movement of the pressure block 3, the first spring 6 is compressed. Since the metal rod has been subjected to sufficient pressure by the pressure block 3, the metal rod begins to move. Bending occurs under the action of the pressing block 3, and if the pressing block 3 continues to be pressed down, the second pressing plate 13 and the first pressing plate 10 at the top of the mounting plate 7 begin to move relative to each other through the extrusion block of the pressing block 3, and the second pressing plate 13, the first pressing plate 10 and the inclined surface adapted to the extrusion block can allow the pressing block 3 to smoothly extrude the second pressing plate 13 and the first pressing plate 10, and pressure is applied to both ends of the metal rod through the second pressing plate 13 and the first pressing plate 10, ensuring that the metal rod remains stable during the bending process while causing secondary deformation of the metal rod while being pressed down.
[0025] See also Figure 2 , Figure 5 , Figure 6 An adjusting assembly is installed inside the top plate 2, and the adjusting assembly includes a motor 14 installed inside the top plate 2, one end of the motor 14 is rotatably connected to a first turntable 15, a sliding groove 16 is installed on one side outer wall of the first turntable 15, a sliding block 17 is slidably connected to the inner wall of the sliding groove 16, a screw rod 18 is connected to the inner wall of the sliding block 17, a second turntable 19 is connected to one side outer wall of the sliding block 17, and a push rod 20 is connected to one side outer wall of the second turntable 19.
[0026] It should be noted that: the outer wall of the motor 14 is fixedly connected to the inner wall of the top plate 2, and the first turntable 15 is driven to rotate by starting the motor 14. A sliding groove 16 is installed on the outer wall of one side of the first turntable 15. The sliding groove 16 is used to guide and limit the movement direction of the sliding block 17. A sliding connection is formed between the inner wall of the sliding groove 16 and the sliding block 17, so that the sliding block 17 can move smoothly along the length direction of the sliding groove 16 without leaving the track. The sliding block 17 can be adjusted on the inner wall of the sliding groove 16 by rotating the screw rod 18, so that the second turntable 19 and the central rotation position of the motor 14 are offset. The adjustment of the sliding block 17 by the screw rod 18 can change the distance that the push rod 20 drives the pressing block 3 to press down, and the metal rod has different bending shape adjustments.
[0027] participate Figure 2 The bottom end of the push rod 20 is connected with a pressing block 3, and the top end of the pressing block 3 is fixedly connected to the bottom end of the push rod 20.
[0028] It should be noted that the fixed connection ensures that the push rod 20 and the pressing block 3 will not be accidentally separated during operation, thereby reducing the safety risks caused by the detachment of components.
[0029] See also Figure 3 The bottom end of the pressing rod 5 is provided with a first slot, the outer walls of the second pressing plate 13 and the first pressing plate 10 are both provided with a second slot, and the outer wall of the mounting plate 7 is provided with a third slot.
[0030] It should be noted that the interaction force between the first slot and the metal rod causes the metal rod to gradually undergo plastic deformation. The first slot can accurately control the starting point and end point of the deformation, as well as the speed and degree of the deformation. The second slot and the third slot cooperate with the first slot to jointly constitute a clamping and positioning mechanism for the metal rod.
[0031] See also Figure 3 The outer walls of the first pressing plate 10 and the second pressing plate 13 are both provided with inclined surfaces, and the width of the inclined surfaces is adapted to the extrusion blocks on both sides of the bottom end of the pressing block 3.
[0032] It should be noted that the inclined surface cooperates with the extrusion block to enhance the clamping stability of the first pressing plate 10 and the second pressing plate 13 on the metal rod.
[0033] Working principle: the pressure block 3 is pushed out by the push rod 20, and after the pressure block 3 is pushed out, the metal rod is bent by the pressure rod 5 inside the pressure block 3. At the same time, the first slot, the second slot and the third slot can appropriately limit the metal rod to ensure the stability of the metal rod when bending. If the pressure block 3 is pressed down, the slider 4 and the pressure rod 5 slide on the inner wall of the pressure block 3, and the extrusion blocks on both sides of the bottom end of the pressure block 3 perform relative extrusion movement on the second pressure plate 13 and the first pressure plate 10, so that the second pressure plate 13 and the first pressure plate 10 are close to each other, and the metal rod is completely extruded and formed. At the same time, the first spring 6, the second spring 9 and the third spring 12 can directly rebound after the extrusion action is completed to reset the component.
