Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine capable of rapid position limiting. Background Art

[0002] Bending is the process of metal sheet undergoing elastic deformation and then plastic deformation under the pressure of the upper or lower die. As the upper or lower die applies pressure to the sheet, the sheet and the inner surface of the V-groove of the lower die gradually come close to each other. At the same time, the radius of curvature and the bending arm gradually become smaller. The pressure is continued until the stroke ends, so that the upper and lower dies are in full contact with the sheet at three points. At this time, a V-shaped bend is completed, which is commonly known as bending. The bending machine is a very common mechanical equipment in the bending process. It is a machine that can bend thin plates, and the needs of various workpieces can be met by replacing the bending machine mold.

[0003] During the production and processing, when a bending machine is needed for assistance, the main body of the bending machine is first moved to the designated location, and then the hydraulic cylinder on the mounting bracket is started to move the bending seat up and down along the limit column until the bending seat docks with the material on the bending die, thereby completing the bending of the material; but during the use of the bending machine, in order to process different workpieces, different bending dies often need to be replaced. However, when people replace the bending die, they usually need to rotate the bolts through the outer wall of the bending die to limit the bending die and then complete the replacement of the bending die. However, this method of replacing the bending die is time-consuming and labor-intensive, and is not convenient enough. It requires repeated rotation of multiple sets of bolts to complete the replacement, which is not convenient enough, thus affecting the use of the bending machine. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 6 The utility model provides a technical solution: a bending machine capable of rapid position limiting, comprising a bending machine body 1, a mounting bracket 2 and a bending seat 4, a mounting bracket 2 is docked on one side of the top of the bending machine body 1, a hydraulic cylinder 3 is docked on the middle of the top of the mounting bracket 2, and a bending seat 4 is docked on the output end of the hydraulic cylinder 3, and a limiting column 5 is slidably connected to both sides of the outer wall of the bending seat 4, a bending mold 6 is connected to the middle of the top of the bending machine body 1, and a limiting mechanism 7 is arranged on the outer wall of the bending mold 6, and the limiting mechanism 7 comprises an electric push rod 71, a lifting plate 72, a limiting rod 73, a guide seat 74, a slide rail 75, a guide plate 76, a limiting seat 77, a fixing pin 78 and a spring 79, an electric push rod 71 is docked inside the bending machine body 1, and the output end of the electric push rod 71 is connected to the There is a lifting plate 72 docked therewith; the limiting rods 73 are slidably connected to the two sides of the lifting plate 72, and a guide seat 74 is welded to the top of the lifting plate 72; a slide rail 75 is slidably connected to the top of the guide seat 74, and a guide plate 76 is welded to the outer wall of the slide rail 75; the middle part of the guide plate 76 is rotatably connected to the limiting seat 77, and a fixing pin 78 is slidably connected to the limiting seat 77 through a guide cavity; a spring 79 is sleeved on the outer wall of the fixing pin 78, and an elastic telescopic mechanism is formed between the limiting seat 77, the fixing pin 78 and the spring 79; the limiting rod 73 is connected to the bending machine body 1 at the upper and lower sides, the guide seat 74 is slidably connected to the bending machine body 1, the bottom end of the limiting seat 77 is connected to the bending machine body 1, and fixing holes docking with the fixing pin 78 are opened on both sides of the bottom end of the bending mold 6.

[0027] During specific implementation, when the bending machine is needed to assist in the production and processing process, in order to process different workpieces and replace different bending molds 6, the electric push rod 71 is first started. Since the output end of the electric push rod 71 is connected to the lifting plate 72, the electric push rod 71 extends to make the lifting plate 72 move upward. Since the lifting plate 72 is slidably connected to the limiting rod 73, the movement of the lifting plate 72 is guided by the limiting rod 73. Since the top end of the lifting plate 72 is connected to the guide seat 74, the movement of the lifting plate 72 drives the guide seat 74 to move together.

[0028] Then, the top end of the guide seat 74 slides along the slide rail 75, thereby generating a thrust on the guide plate 76, so that the guide plate 76 rotates along the limit seat 77, and then the guide plate 76 rotates to squeeze the fixed pin 78, causing the fixed pin 78 to move downward along the limit seat 77, and the fixed pin 78 squeezes the spring 79 when moving downward, so that the spring 79 is deformed until the fixed pin 78 docks with the bending die 6;

[0029] Then, the bending die 6 is limited to prevent the bending die 6 from moving at will, and then the bending die 6 can be replaced without repeatedly rotating multiple sets of bolts to penetrate the bending die 6, and the subsequent disassembly of the bending die 6 is convenient, so that when the bending machine is used, it plays a role in facilitating the rapid limitation of the bending die 6;

[0030] When the bending mold 6 needs to be disassembled, the electric push rod 71 is first started to contract and drive the lifting plate 72 to move downward, and then the guide seat 74 moves downward to rotate the guide plate 76. At this time, the guide plate 76 rotates upward close to the fixing pin 78, thereby canceling the squeezing of the fixing pin 78. At this time, the spring 79 is reset to drive the fixing pin 78 to move upward until the fixing pin 78 is disconnected from the bending mold 6, and then the fixation of the bending mold 6 is canceled, thereby making it convenient for people to disassemble the bending mold 6.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 It can be seen that an auxiliary mechanism 8 is arranged on the outer wall of the bending machine body 1, and the auxiliary mechanism 8 includes a fixed seat 81, a support seat 82, a support platform 83, a storage box 84, a limit plate 85 and a clamping seat 86. Fixed seats 81 are welded on both sides of the outer wall of the bending machine body 1; the interior of the fixed seat 81 is connected with the support seat 82 through the installation cavity, and a support platform 83 is welded on one side of the outer wall of the support seat 82, and the top of the support platform 83 is connected with the storage box 84; one side of the outer wall of the storage box 84 is connected with the limit plate 85 through a rotating seat, and a clamping seat 86 is docked on the side of the top of the bending machine body 1 close to the limit plate 85; a limit hole docked with the limit plate 85 is opened inside the clamping seat 86, and the clamping seat 86 is symmetrically distributed about the vertical center line of the bending machine body 1, and a rotating seat docked with the limit plate 85 is welded on the outer wall of the storage box 84.

[0032] In specific implementation, during the production and processing, when the bending machine is needed to assist, in order to facilitate the bending of the workpiece, when the material needs to be placed at the worker's hand, because the fixing seat 81 has an installation cavity connected to the support seat 82, the support seat 82 is first manually slid into the fixing seat 81, because the support seat 82 is connected to the support platform 83, and then the support platform 83 is set on both sides of the bending machine body 1, and then the storage box 84 is placed on the support platform 83;

[0033] Because the storage box 84 and the limit plate 85 are rotatably connected, the limit plate 85 is first manually rotated to make the limit plate 85 rotate along the storage box 84 until the limit plate 85 is docked with the clamping seat 86, and then the storage box 84 is limited to prevent the storage box 84 from moving at will. At this time, according to the workers' usage habits, unbent workpieces and bent workpieces are placed in different storage boxes 84 respectively, so that the workers can take and place the workpieces at will, saving time and thus improving work efficiency, thereby facilitating the storage of workpieces when the bending machine is in use.

[0034] To sum up, when this kind of bending machine with rapid limit is used, the bending machine body 1 is first moved to the designated location, and then the hydraulic cylinder 3 on the mounting bracket 2 is started, so that the bending seat 4 moves up and down along the limit column 5 until the bending seat 4 docks with the material on the bending die 6, thereby completing the bending of the material. This is the prior art and will not be elaborated on here. The bending die 6 is limited by the limit mechanism 7 to prevent the bending die 6 from moving at will, and the replacement of the bending die 6 can be completed without repeatedly rotating multiple sets of bolts to penetrate the bending die 6, and the subsequent disassembly of the bending die 6 is convenient. The unbent workpiece and the bent workpiece are placed in the storage box 84 through the auxiliary mechanism 8, respectively, so that the workers can pick up and place the workpieces at hand, saving time and thus improving work efficiency.
