Description

Technical Field

[0001] The utility model belongs to the technical field of tooling, and in particular relates to an auxiliary device for cone forming. Background Art

[0002] At present, the conventional spinning forming of conical thin-walled rotating parts is to fix the flat blank on the core mold of the spinning machine through a top block. While the blank rotates around the main axis of the machine tool, the blank is pressurized by the spinning wheel to cause local plastic deformation to obtain a conical thin-walled rotating part. Its most important feature is that the thickness of the blank remains basically unchanged or slightly reduced during the forming process.

[0003] The spinning machine in the prior art currently uses a spinning wheel to gradually apply pressure to the blank from the axis to the edge to form it. Since the friction between the spinning wheel and the blank is large when the blank is spin-formed, the wear of the spinning wheel may be aggravated, thereby shortening the service life of the spinning wheel. In view of this, the present utility model is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Embodiment 1:

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An auxiliary device for cone forming includes a workbench 1, and also includes: a rotating shaft 101 rotatably connected to the workbench 1, wherein the rotating shaft 101 is detachably connected with a cone mold 102 and a blank 104; a sleeve 4, which is liftably connected just above the rotating shaft 101 and is slidably connected to the workbench 1; a piston disc 402, which is slidably connected in the sleeve 4, wherein a spring 401 is fixedly connected between the piston disc 402 and the inner wall of the sleeve 4, and a connecting rod 403 is fixedly connected to the piston disc 402, and the connecting rod One end of 403 passes through the sleeve 4 and is fixedly installed on the mounting seat 404, on which the driving shaft 405 is rotatably connected; a clamping assembly is arranged on the driving shaft 405; a pressure wheel 407 is detachably connected to the driving shaft 405 through the clamping assembly; a liquid storage tank 601 is fixedly installed on the workbench 1, wherein the liquid storage tank 601 is fixedly connected to the sleeve 4 through a pipe 1 6, and an atomizing nozzle 603 is fixedly connected to the mounting seat 404, and the atomizing nozzle 603 is fixedly connected to the sleeve 4 through a pipe 2 602.

[0025] A motor 2 is fixedly mounted on the workbench 1 , a gear 201 is fixedly connected to the output end of the motor 2 , and a gear 202 meshing with the gear 201 is fixedly connected to the rotating shaft 101 .

[0026] It also includes a hydraulic telescopic rod 304 connected to the workbench 1 , and the sleeve 4 is fixedly connected to the output end of the hydraulic telescopic rod 304 .

[0027] It also includes a screw rod 301 rotatably connected to the workbench 1, a guide rod 302 is fixedly installed on the workbench 1, a connecting seat 303 is fixedly connected to the outer wall of the hydraulic telescopic rod 304, the connecting seat 303 is threadedly connected to the screw rod 301, and is slidably connected to the guide rod 302, a motor 2 3 is fixedly installed on the workbench 1, and the screw rod 301 is fixedly connected to the output end of the motor 2 3.

[0028] When in use, first install and fix the conical mold 102 and the blank 104 on the rotating shaft 101 in sequence, then start the hydraulic telescopic rod 304, the hydraulic telescopic rod 304 pushes the sleeve 4 to move downward, and at the same time, the sleeve 4 pushes the pressure wheel 407 to move downward synchronously through the connecting rod 403 and the mounting seat 404. When the bottom end of the pressure wheel 407 is parallel to the top end of the conical mold 102, start the motor 12 and the motor 23. The motor 12 is connected to the gear 1 201 and the gear 2 202 through the meshing connection to drive the rotating shaft 101 to rotate, and the rotating shaft 10 1 drives the conical die 102 and the blank 104 to rotate synchronously, and at the same time, the motor 2 3 drives the screw 301 to rotate. The screw 301 drives the sleeve 4 through the connecting seat 303 to drive the pressure wheel 407 to move to the side close to the conical die 102. When the pressure wheel 407 contacts the blank, the pressure wheel 407 gradually applies pressure to the blank 104 from the axis to the edge, so that the pressure gradually spreads from point to line and then to the surface, and then the rotating blank 104 is deformed under the action of pressure, and is tightly fitted with the conical die 102 to be formed;

[0029] At the same time, when the pressure wheel 407 gradually applies pressure to the blank 104 from the axis to the edge, the pressure wheel 407 pushes the piston plate 402 to slide upward in the sleeve 4 through the connecting rod 403 and compresses the spring 1 401 (it should be noted that the elastic contraction force of the spring 1 401 is greater than the pressure applied by the pressure wheel 407 on the blank 104, so it can ensure that the pressure wheel 407 can spin-form the blank 104 in cooperation with the conical mold 102). At the same time, when the piston plate 402 slides upward in the sleeve 4, the piston plate 402 squeezes the lubricant stored in the sleeve 4 and transports it into the atomizing nozzle 603 through the pipeline 2 602, and sprays it through the atomizing nozzle 603 and sprays it on the surface of the pressure wheel 407, thereby achieving a lubricating effect on the pressure wheel 407, thereby reducing the friction force of the pressure wheel 407 gradually applying pressure to the blank 104 from the axis to the edge, thereby achieving the purpose of extending the service life of the pressure wheel 407;

[0030] It should be noted that when the pressure wheel 407 is separated from the conical mold 102, the compressed spring 1 401 generates thrust, pushing the piston disc 402 to slide downward in the sleeve 4 to reset, and absorbs the lubricant on the inner wall of the liquid storage tank 601 through the pipe 1 6 and reserves it in the sleeve 4. Both pipe 1 6 and pipe 2 602 are provided with one-way valves.

[0031] It should be noted that both pipe 2 602 and pipe 1 6 are made of stretchable hoses, so pipe 2 602 will not interfere with the up and down reciprocating motion of the piston disk 402 , and pipe 1 6 will not interfere with the left and right reciprocating motion of the connecting seat 303 .

[0032] Embodiment 2:

[0033] Reference Figure 3 , Figure 5 and Figure 6 , an auxiliary device for cone forming, which is basically the same as Example 1, and further, the clamping assembly includes a fastening disk 406, which is fixedly installed on the driving shaft 405; it also includes a groove 5 symmetrically opened on the driving shaft 405, and a clamping block 501 is slidably connected in the groove 5, and a spring 2 502 is fixedly connected between the clamping block 501 and the inner wall of the groove 5, and the clamping block 501 is clamped on the surface of the outer wall of the pressure wheel 407.

[0034] When the pressure wheel 407 is worn out and affects the spin forming of the blank 104 with the conical mold 102, the operator presses the clamping block 501, and the clamping block 501 slides into the groove 5 after being pressed, and compresses the spring 2 502 until the clamping block 501 is completely retracted into the groove 5, so that the limiting fixation of the pressure wheel 407 is released, and then the pressure wheel 407 can be removed from the driving shaft 405, so as to achieve the effect of more convenient disassembly and replacement of the pressure wheel 407;

[0035] When installing and fixing the pressure wheel 407, the pressure wheel 407 is first sleeved on the driving shaft 405 and fits with the fastening disk 406. At the same time, when the pressure wheel 407 is sleeved on the driving shaft 405 and moves toward the side close to the fastening disk 406, the clamping block 501 is squeezed by the outer wall of the pressure wheel 407 and slides into the groove 5, and compresses the spring 2 502 until the clamping block 501 is completely retracted into the groove 5. When the pressure wheel 407 fits with the fastening disk 406, the groove 5 is separated from the mounting hole provided on the pressure wheel 407, and then the spring 2 502 is compressed to generate a thrust, pushing the clamping block 501 to move out of the groove 5 and clamped on the surface of the outer wall of the pressure wheel 407, thereby achieving a limited fixation effect on the pressure wheel 407, thereby achieving a more convenient installation and fixation of the pressure wheel 407.
