Description

Technical Field

[0002] The wheel roll forming machine is a special equipment for forming wheel rims. It transmits torque to the upper and lower spindles of the equipment through the driving part, and sends it into the oil cylinder to provide lifting force. It cooperates with the mold installed on the spindle and is cold rolled with the assistance of the side guide mechanism. The side guide mechanism plays a vital role in the wheel rim forming process, so the stability and safety of the side guide mechanism directly affect the precision of the wheel rim product and the stability of the equipment.

[0048] The present invention will be further explained below in conjunction with specific implementation methods.

[0049] Example 1

[0050] like Figure 1-3 As shown, the present embodiment provides a rotary roller type side guide mechanism, comprising: a side guide device 2, a drive assembly 3 and a mounting seat assembly 4;

[0051] The side guide device 2 includes a guide wheel assembly 25, which is used to limit the radial and axial position of the rim 5 during rolling;

[0052] The side guide device 2 is reciprocatingly mounted on the mounting seat assembly 4 and is used to move the device closer to the wheel rim 5 during rolling or farther away from the wheel rim 5 during unloading.

[0053] The driving assembly 3 is used to drive the side guide device 2 to swing.

[0054] The mounting seat assembly 4 includes a ground mounting seat 41 and a lower mounting seat 42 spaced apart from each other; the upper mounting seat 41 is used for mounting and fixing the drive assembly 3, and the lower mounting seat 42 is used for mounting and fixing the side guide device 2;

[0055] The upper mounting seat 41 and the lower mounting seat 2 are both fixedly mounted on the bed 1 of the rolling machine.

[0056] The side guide device 2 further includes a rotating shaft 21, which is fixedly mounted on the lower mounting seat 42;

[0057] The axis of the rotating shaft 21 is arranged parallel to the axis of the main shaft of the rolling machine;

[0058] A swing frame 22 is rotatably mounted on the rotating shaft 21 .

[0059] A guide wheel seat 23 is provided on one side of the swing frame 22 away from the rotating shaft 21. The guide wheel seat 23 can move along the axis of the rotating shaft 21 to adjust the position of the guide wheel seat 23 and the guide wheel assembly 25.

[0060] After the position of the guide wheel seat 23 is adjusted, the guide wheel seat 23 and the swing frame 22 are fastened together by the fastening screws 24; an oblong hole is opened on the swing frame 22 for avoiding the fastening screws 24 when the guide wheel seat 23 moves.

[0061] The guide wheel assembly 25 includes a guide wheel shaft 251, which is fixed to the guide wheel seat 23;

[0062] A shaft sleeve 252 is rotatably mounted on the guide wheel shaft 251 .

[0063] According to the rolling process requirements of rims 5 of different specifications, the shaft sleeve 252 is rotatably provided with a middle guide wheel 253 or fixedly and spaced apart with a side guide wheel 254 , or the middle guide wheel 253 and the side guide wheel 254 can be provided in combination.

[0064] Among them, the middle guide wheel 253 belongs to the mold, and the outer contour surface of the middle guide wheel 253 is adapted to the middle surface of the rolled rim 5. The middle guide wheel 253 cooperates with the upper rolling mold and the lower rolling mold of the rolling machine to complete the rolling forming of the rim 5, and limits the rim 5 axially and radially during the rolling process.

[0065] In this embodiment, only the middle guide wheel 253 is sleeved on the outer surface of the shaft sleeve 252 on one side, and the middle guide wheel 253 and the side guide wheel 254 are sleeved on the outer surface of the shaft sleeve 252 on the other side.

[0066] Specifically, such as Figure 4 As shown, the middle guide wheel 253 is sleeved in the middle position of the shaft sleeve 252, and a bearing sleeve 257 and a bearing 256 are also sleeved between the shaft sleeve 252 and the middle guide wheel 253, and a locking nut 255 is provided on one side of the bearing sleeve 257. The locking nut 255 cooperates with the limit platform provided on the shaft sleeve 252 to axially fix the bearing sleeve 257.

[0067] like Figure 5 As shown, a middle guide wheel 253 and two side guide wheels 254 are sleeved on the outer side of the shaft sleeve 252, and the side guide wheels 254 are symmetrically arranged on both sides of the middle guide wheel 253;

[0068] The side guide wheel 254 is arranged in a cone shape on the side in contact with the rim 5, and is used to limit the axial and radial positions of both ends of the rim 5 during rolling;

[0069] A plurality of spacers are provided between the side guide wheels 254 for adjusting the distance between the two side guide wheels 254 .

[0070] According to the rolling requirements of rims 5 of different widths, different numbers and thicknesses of spacers are selected to adjust the spacing between the two side guide wheels 254; locking nuts 255 are provided on the outside of the two side guide wheels 254. After the positions of the two side guide wheels 254 are adjusted, the side guide wheels 254 are fastened to the shaft sleeves 252 with locking nuts.

[0071] like Figure 6 As shown, the side guide device 2 further includes an adjustment assembly 26 for driving the guide wheel seat 23 to move along the axis direction of the rotating shaft 21;

[0072] The adjustment assembly 26 includes an adjustment screw 261 and a fixing seat 262. The adjustment screw 261 is arranged parallel to the sliding direction of the guide wheel seat 23;

[0073] An open long slot 221 is provided on one side of the swing frame 22, and an ear plate 231 matching the width of the open long slot 221 is provided on the guide wheel seat 23;

[0074] One end of the adjusting screw 261 extends into the open long slot 221 and is threadedly connected to the ear plate 231, and the other end is rotatably disposed through the fixing seat 262;

[0075] The fixing seat 262 is fixedly connected to the swing frame 22 .

[0076] One end of the adjusting screw 261 extending out of the fixing seat 262 is provided with a clamping portion for clamping a tool such as a wrench.

[0077] The clamping portion is a regular quadrilateral or a regular hexagon, etc., which is convenient for the wrench to clamp and rotate.

[0078] Specifically, first loosen the fastening screw 24 that fastens the swing frame 22 and the guide wheel seat 23, then rotate the adjusting screw 261, and the adjusting screw 261 drives the guide wheel seat 23 and the guide wheel assembly 25 to move back and forth along the swing frame 22 through the ear plate 231 on the guide wheel seat 23, so that the middle guide wheel 253 or the side guide wheel 254 reaches the required limit position, and then tighten the fastening screw 24 to fasten the swing frame 22 and the guide wheel seat 23.

[0079] By fine-tuning the position of the guide wheel seat 23 by adjusting the assembly 26, the position of the guide wheel assembly 25 can be aligned with the surface of the rim 5, thereby improving the accuracy of guiding and limiting the rim 5 and the accuracy of rolling the rim 5.

[0080] The driving assembly 3 includes a telescopic mechanism, the telescopic end of which is hinged to the swing frame 22 and is used to drive the side guide device 2 to rotate around the rotating shaft 21;

[0081] The body of the telescopic mechanism is hinged with an elevator 32 .

[0082] The telescopic mechanism is a telescopic cylinder 31, a telescopic oil cylinder or an electric push rod.

[0083] In this embodiment, the telescopic mechanism is a telescopic cylinder 31 .

[0084] The elevator 32 is fixedly mounted on the upper mounting seat 41 , and the telescopic end of the elevator 32 is hinged to the body of the telescopic cylinder 31 , and is used to drive the telescopic cylinder 31 to move along the telescopic direction to achieve the initial position required for rolling rims 5 of different diameters.

[0085] The provision of the elevator 32 improves the accuracy of the side guide device 2 reaching the initial position, thereby improving the accuracy of the side guide device 2 in guiding and limiting the rim 5.

[0086] Specifically, the stroke of the telescopic cylinder 31 is fixed. When the telescopic end of the elevator 32 is extended a long distance, the telescopic cylinder 31 body is closer to the upper spindle 8 and the lower spindle 7 of the rolling machine. Correspondingly, the guide wheel assembly 25 can reach a position closer to the upper spindle 8 and the lower spindle 7 of the rolling machine during rolling, and guide and limit the wheel rim 5 with a smaller diameter; conversely, when the telescopic end of the elevator 32 is extended a short distance, the telescopic cylinder 31 body is farther away from the upper spindle 8 and the lower spindle 7 of the rolling machine. Correspondingly, the guide wheel assembly 25 is farther away from the upper spindle 8 and the lower spindle 7 of the rolling machine during rolling, and can guide and limit the wheel rim 5 with a larger diameter.

[0087] During operation, the extension distance of the telescopic end of the elevator 32 is manually adjusted according to the diameter of the rim 5 of different models of products, so that the swing frame 22 and the guide wheel assembly 25 are located in the set initial position; then the adjusting screw 261 is rotated to adjust the position of the guide wheel seat 23 so that the guide wheel assembly 25 is facing the rim 5 profile; then the lifting lower spindle 7 and the rim 5 of the lifting cylinder 6 are lifted up, and when the rim 5 approaches the upper rolling mold of the upper spindle 8, the telescopic ends of the telescopic cylinders 31 on both sides are extended at the same time, driving the swing frame 22, the guide wheel seat 23 and the guide wheel assembly 25 to rotate inward around the axis of the rotating shaft 21, so that the middle guide wheel 253 and the side guide wheel 254 are close to the rim 5, forming radial and axial guidance and limitation for the rim 5 when the rim 5 rotates and rolls.

[0088] Bearings are also provided between the rotating shaft 21 and the swing frame 22, and between the guide wheel shaft 251 and the shaft sleeve.

[0089] Example 2

[0090] This embodiment is basically the same as embodiment 1, except that:

[0091] like Figure 7 As shown, only two side guide wheels 254 are mounted on the shaft sleeves 252 of the guide wheel assemblies 25 on both sides, which are used for axial and radial limiting of the rim 5 during rolling.

[0092] According to the rolling process requirements of the rim 5, an appropriate guide wheel installation combination is selected, which greatly improves the versatility of the side guide device 2 assembly.

[0093] The utility model provides a rotary roller side guide mechanism with the following advantages:

[0094] 1. The rim rolling is guided and limited by the side guide device swinging around the axis of the rotating shaft, which solves the problem of unstable guidance and reduced equipment accuracy caused by sliding wear of the guide plate in conventional self-lubricating guide plate type side guide devices. It greatly improves the guiding and limiting stability of the side guide device and the processing accuracy of the equipment, thereby improving the rolling quality of the rim.

[0095] 2. The utility model has a compact structure, is easy to adjust and install, and has a low manufacturing cost; at the same time, the rotational wear of the bearing is lower than the sliding wear of the guide plate, which greatly reduces the repair and maintenance costs of parts.
