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.

[0021] See also Figure 1-4 , an embodiment provided by the utility model:

[0022] A forming device for processing a suspension spring comprises: a processing box 111, a bending box 112, an inlet 113, a conveying cavity 114, a fixing plate 115 and a servo motor 116. The rear end of the processing box 111 is connected to the bending box 112. The front end of the processing box 111 is provided with an inlet 113. The conveying cavity 114 is provided at the connection between the processing box 111 and the bending box 112. A limiting structure 2 is provided inside the processing box 111. A mounting structure 3 is provided inside the processing box 111. The limiting structure 2 comprises a positioning cylinder 211. The positioning cylinder 211 is provided with a mounting structure 3. 211 is arranged inside the processing box 111, and the two ends of the positioning cylinder 211 are respectively connected to the inlet 113 and the conveying chamber 114, and the outer wall of the positioning cylinder 211 is fixedly provided with a fixing plate 115, and the bottom end of the fixing plate 115 is provided with a servo motor 116, and the output shaft of the servo motor 116 is fixedly connected with a rotating rod 212, and the other end of the rotating rod 212 is connected to a conveying wheel 213, and the output shaft of the fixing plate 115 is connected with another set of rotating rods 212 through a belt, and the inner wall of the processing box 111 is fixedly provided with a fixing column 214, and the fixing column 214 is fixedly provided with a fixing column 214. A movable column 215 is inserted in the part, and a clamping plate 216 is fixedly arranged at one end of the movable column 215 away from the fixed column 214. The clamping plate 216 is slidably arranged in the positioning cylinder 211. A fixing rod 217 is inserted in the movable column 215, and a first spring 218 is wound around the surface of the fixing rod 217. Through this design, the suspension spring to be processed and formed is transported from the inlet 113 into the positioning cylinder 211, so that one end of the suspension spring is arranged in the bending box 112, and the fixing plate 115 is started to drive the rotating rod 212 to rotate, and the belt Under the action of , multiple groups of conveying wheels 213 are driven to rotate synchronously to convey the spring. When the spring enters, the movable column 215 is pulled first to drive the clamping plate 216 to move away from the positioning cylinder 211. At this time, the first spring 218 is in a compressed and force-accumulating state. When the suspension spring passes through the inside of the positioning cylinder 211, the movable column 215 can be released, and the elastic force of the first spring 218 can be used to clamp and limit the suspension spring, but the suspension spring will not be clamped, so that the suspension springs of different diameters can be guaranteed to move horizontally.

[0023] Furthermore, one end of the first spring 218 is connected to a damper 219, and the damper 219 is installed inside the fixing column 214. Through this design, the first spring 218 transfers the force to the damper 219 for decomposition, thereby avoiding repeated vibration of the first spring 218.

[0024] Furthermore, a slider 220 is fixedly provided on the side wall of the movable column 215. The slider 220 is inserted into a slide groove 221. The slide groove 221 is opened inside the fixed column 214.

[0025] Furthermore, the mounting structure 3 includes a support seat 311, which is fixedly arranged at the bottom end of the positioning cylinder 211, a mounting seat 312 is fixedly arranged on the outer wall of the support seat 311, a mounting rod 313 is inserted inside the mounting seat 312, and the bottom end of the mounting rod 313 is inserted inside the processing box 111, an insertion rod 314 is inserted inside the mounting rod 313, a pull rod 315 is fixedly arranged on the upper end of the insertion rod 314, and the end of the insertion rod 314 away from the mounting rod 313 is inserted in the insertion cavity 316 The insertion cavity 316 is opened inside the processing box 111. Through this design, when the positioning cylinder 211 cannot meet the current transportation demand of the suspension spring, the pull rod 315 can be pulled to drive the insertion rod 314 to move and move it out of the installation rod 313, and then the installation rod 313 is moved out of the processing box 111 and the mounting seat 312, and then the moving column 215 is pulled to move the clamping plate 216 out of the positioning cylinder 211, and the positioning cylinder 211 can be disassembled and assembled for easy adaptation and use.

[0026] Furthermore, a second spring 317 is fixedly provided at one end of the insertion rod 314 away from the mounting rod 313, and the other end of the second spring 317 is fixedly provided on the inner wall of the insertion cavity 316 away from the insertion rod 314. Through this design, when it is necessary to install the positioning cylinder 211, first pull the pull rod 315 to drive the insertion rod 314 to move in the direction away from the mounting rod 313, and then install the support seat 311 and the mounting seat 312 to the upper end of the inner wall of the processing box 111, and then simultaneously insert the mounting seat 312 and the processing box 111 into the interior. At this time, the second spring 317 is in a compressed and force-accumulating state, and the pull rod 315 is released. The elastic force of the second spring 317 can automatically drive the pull rod 315 to enter the interior of the insertion rod 314, thereby completing a convenient installation.

[0027] Furthermore, a limit block 318 is fixedly provided on the side wall of the insertion rod 314, and the limit block 318 is inserted into the limit groove 319. The limit groove 319 is opened inside the processing box 111. Through this design, when the insertion rod 314 moves, the limit block 318 moves synchronously inside the limit groove 319, thereby realizing the limiting effect on the insertion rod 314 and making its movement more stable.

[0028] Working principle:

[0029] The suspension spring to be processed and formed is conveyed from the inlet 113 into the positioning cylinder 211, so that one end of it is set inside the bending box 112, and the fixed plate 115 is started to drive the rotating rod 212 to rotate. Under the action of the belt, multiple sets of conveying wheels 213 are driven to rotate synchronously to convey the spring. When the spring enters, the moving column 215 is pulled first to drive the clamping plate 216 to move away from the positioning cylinder 211. At this time, the first spring 218 is in a compressed and force-accumulating state. When the suspension spring passes through the positioning cylinder 211, the moving column 215 can be loosened, and the elastic force of the first spring 218 can be used to clamp and limit the suspension spring, but the suspension spring will not be clamped, so that the suspension springs of different diameters can be guaranteed to move horizontally.

[0030] When the positioning cylinder 211 cannot meet the current suspension spring delivery requirements, the pull rod 315 can be pulled to drive the insertion rod 314 to move it out of the installation rod 313, and then the installation rod 313 can be moved out of the processing box 111 and the mounting seat 312, and then the moving column 215 can be pulled to move the clamping plate 216 out of the positioning cylinder 211, and the positioning cylinder 211 can be disassembled and assembled for convenient adaptation and use. When the adapted positioning cylinder 211 needs to be installed, the pull rod 315 is first pulled to drive the insertion rod 314 to move in a direction away from the mounting rod 313, and then the support seat 311 and the mounting seat 312 are installed to the upper end of the inner wall of the processing box 111, and then the mounting rod 313 is synchronously inserted into the mounting seat 312 and the processing box 111. At this time, the second spring 317 is in a compressed and stored state, and the pull rod 315 is released, and the elastic force of the second spring 317 can automatically drive the pull rod 315 to enter the insertion rod 314 to complete the convenient installation, and the operation is completed.
