Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art; Press-roller device on a kind of mechanical arbor press is provided; Not only can correct the H shaped steel of standard, can also correct web height is 120mm～200mm, and wing plate thickness reaches the manganese template steel of the trade mark Q345 of 16mm.
According to the technical scheme that the utility model provides, the press-roller device on the said mechanical arbor press comprises the lifting slider seat of the rectification home roll both sides that are installed on the arbor press frame, on the lifting slider seat of both sides, the pressure roller assembly is installed respectively; Said pressure roller assembly comprises pressure roller shaft and the last pressure roller that is installed in the pressure roller shaft front end, and last pressure roller stretches out the lifting slider seat; Characteristic is: the said outer surface of going up pressure roller is provided with step, forms first step and second step, and the outer surface of said first step and second step is the conical surface; Said first step is arranged on the side of the front end of second step near small-sized H-shaped steel or standard H shaped steel, and the maximum gauge of first step male cone (strobilus masculinus) is less than the minimum diameter of second step male cone (strobilus masculinus).
The external diameter of said first step and the height of small-sized H-shaped steel are complementary, and the height of the external diameter of said second step and standard H shaped steel is complementary.Sheathed duplex needle bearing of difference and self lubrication bearing on the said pressure roller shaft.The upper end of said lifting slider seat is fixedly connected with lift shaft.Between said lifting slider seat and last pressure roller, the high thrust ball bearing is set.Said pressure roller shaft is installed in lifting slider seat inside through pressure roller shaft terminal locking nut and thrust ball bearing.
Compared with present technology the utility model has the following advantages: (1), the utility model adopt the last pressure roller of two-layer tapering, have both satisfied the H shaped steel of rectification standard, also can satisfy and correct small-sized H shaped steel; And need not change pressure roller, very easy to use, simple; (2), the utility model adopts duplex needle bearing and self lubrication bearing to save the space than the bearing that uses now, and bearing capacity is big, and is convenient and reliable.
Description of drawings
Fig. 1 corrects the sketch map of small-sized H-shaped steel for the utility model.
Fig. 2 corrects the sketch map of standard H shaped steel for the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like Fig. 1 ~ shown in Figure 2: the press-roller device on the mechanical arbor press comprises small-sized H-shaped steel 1, corrects home roll 2, goes up pressure roller 3, high thrust ball bearing 4, duplex needle bearing 5, lift shaft 6, lifting slider seat 7, self lubrication bearing 8, thrust ball bearing 9, locking nut 10, standard H shaped steel 11, arbor press frame 12, pressure roller shaft 13, first step 31, second step 32 etc.
The said press-roller device of the utility model comprises the lifting slider seat 7 of rectification home roll 2 both sides that are installed on the arbor press frame 12, on the lifting slider seat 7 of both sides, the pressure roller assembly is installed respectively; Said pressure roller assembly comprises pressure roller shaft 13 and the last pressure roller 3 that is installed in pressure roller shaft 13 front ends, and pressure roller shaft 13 is installed in lifting slider seat 7 inside through pressure roller shaft 13 terminal locking nuts 10 with thrust ball bearing 9, and last pressure roller 3 stretches out lifting slider seat 7; The said outer surface of going up pressure roller 3 is provided with step, forms first step 31 and second step 32, and the outer surface of said first step 31 and second step 32 is the conical surface; Said first step 31 is arranged on the side of the front end of second step 32 near small-sized H-shaped steel 1 or standard H shaped steel 11, and the maximum gauge of first step 31 male cone (strobilus masculinus)s is less than the minimum diameter of second step 32 male cone (strobilus masculinus)s; The height of the external diameter of said first step 31 and small-sized H-shaped steel 1 is complementary, and the height of the external diameter of said second step 32 and standard H shaped steel 11 is complementary;
