Abstract
The utility model discloses a channel steel lateral bending mould and belongs to the technical field of sectional material bending machines. The channel steel lateral bending mould is provided so as to enable the perpendicularity between wing plates and a web plate, as well as the planeness of the web plate to achieve better accuracy; the utility model adopts the technical scheme that the channel steel lateral bending mould comprises a roller coalition, a roller frame body, a support, a pin shaft, a composite sleeve, a screw rod and a thread sleeve, wherein the support is fixed on a lathe bed, the screw rod and the thread sleeve are fixed above the support, the screw rod is sleeved on the thread sleeve, the thread sleeve is fixedly connected with the roller frame body, the pin shaft is arranged inside the roller frame body, the roller coalition is sleeved on the pin shaft through the composite sleeve, a pin shaft baffle plate is arranged at one end of the pin shaft, the roller coalition comprises a first roller and a second roller, a bearing and an adjustment cushion are arranged between the first roller and the second roller, and the external form of the roller coalition is the same with that of the internal groove of a channel steel; and the channel steel lateral bending mould is used in the technical field of channel steel lateral bending of sectional material bending.
Description
Technical field
The utility model channel-section steel lateral bending mould belongs to the profile bender technical field.
Background technology
Profile bender is when rolling the channel-section steel lateral bending at present, and common way is to be finished by the universal mold of machine.The universal mold of machine only withstands the outside on the wing limit of channel-section steel when rolling, the wing limit of channel-section steel will inwardly be received in the process that rolls like this, and the base of channel-section steel causes the cross section of section bar that rugged change takes place to evagination, in addition, during the channel-section steel lateral bending, because its flexural center is outside the cross section of channel-section steel, if channel-section steel is occured bending and deformation, cross force is acted on the channel-section steel, the cross force action plane is not the centre of form principal plane of inertia, and channel-section steel is except that flexural deformation, and distortion will twist; Make equipment can't roll out qualified workpiece.
The utility model content
The utility model type provides a kind of channel-section steel lateral bending mould, the perpendicularity of wing plate and web when making the channel-section steel lateral bending, and the web plane degree all can reach precision preferably.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: channel-section steel lateral bending mould, comprise: roller combination, roller support body, support, bearing pin, compound cover, screw mandrel and silk braid, support is fixed on the lathe bed, and the upper fixed of support has screw mandrel and silk braid, and screw mandrel is sleeved on the silk braid, silk braid is fixedlyed connected with the roller support body, roller support body inside is provided with bearing pin, and the roller combination is sleeved on the bearing pin by compound cover, is provided with the bearing pin baffle plate at an end of bearing pin.
Described roller combination comprises: first roller and second roller are provided with bearing and adjusting pad between first roller and second roller.
The profile of described roller combination is identical with the inside groove shape of channel-section steel.
Compared with prior art the utlity model has following beneficial effect.
1, screw mandrel is sleeved on the silk braid, silk braid is fixedlyed connected with the roller support body, roller support body inside is provided with bearing pin, the roller combination is sleeved on the bearing pin by compound cover, when rolling channel-section steel, can adjust gap between channel-section steel and the roller combination by screw mandrel and silk braid, the roller combination is supported in the channel-section steel chamber, the bottom that is channel-section steel is compacted, has suppressed the web distortion of channel-section steel, has improved the flatness of channel-section steel web.
2, the profile of roller combination is identical with the inside groove shape of channel-section steel, and in rolling the process of channel-section steel, the inboard of the wing plate of channel-section steel will be compressed by the roller combination, is unlikely to receive inwards, has improved the perpendicularity of channel airfoil plate and web like this.
3, be provided with bearing and adjusting pad between first roller and second roller, the roller combination can be adjusted gap, the left and right sides by bearing and adjusting pad, when channel-section steel moves, the roller combination changes with the change of channel-section steel horizontal level, the roller combination is also along with channel-section steel rotates simultaneously, thereby controlled the distortion of channel-section steel to greatest extent, so just improved the perpendicularity and the flatness that roll section bar.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model channel-section steel lateral bending mould.
Among the figure: 1 is that roller combination, 2 is that roller support body, 3 is that support, 4 is that bearing pin, 5 is that compound cover, 6 is that bearing pin baffle plate, 7 is that bearing, 8 is that adjusting pad, 9 is that screw mandrel, 10 is that silk braid, 11 is that first roller, 12 is second roller.
The specific embodiment
As shown in Figure 1, channel-section steel lateral bending mould, comprise: roller combination 1, roller support body 2, support 3, bearing pin 4, compound cover 5, screw mandrel 9 and silk braid 10, support 3 is fixed on the lathe bed 13, the upper fixed of support 3 has screw mandrel 9 and silk braid 10, screw mandrel 9 is sleeved on the silk braid 10, silk braid 10 is fixedlyed connected with roller support body 2, roller support body 2 inside are provided with bearing pin 4, roller combination 1 is sleeved on the bearing pin 4 by compound cover 5, end at bearing pin 4 is provided with bearing pin baffle plate 6, and described roller combination 1 comprises: be provided with bearing 7 and adjusting pad 8 between first roller 11 and second roller, 12, the first rollers 11 and second roller 12; The profile of described roller combination 1 is identical with the inside groove shape of channel-section steel.
