Furthermore, the purpose of cutting and cutting channel steel at different angles can be achieved by replacing the right-angle cutter 14.

Furthermore, the number and distribution range of the metering pressing blocks 43 can be adjusted, and more accurate measurement of the channel steel size can be realized

Further, different pressures can be obtained by adjusting the ratio of the cross-sectional areas of the master cylinder 29 and the sub-cylinder 39.

Initial position: the clamp plate gear 26 is positioned at the bottom of the vertical clamp plate groove 58, and the transverse clamp plate 15 and the vertical clamp plate 25 are in an opening state. The support form 16 is located adjacent to the support form 18. The main hydraulic cylinder piston 31 abuts against the main hydraulic cylinder stopper 32 at the distal end, and drives the tool rest 13, the right-angle cutter 14 and the transverse clamping plate 15 to be located at the distal end, and the auxiliary hydraulic cylinder piston 40 is located in the middle of the auxiliary hydraulic cylinder 39.

The method for shearing the right angle of the channel steel comprises the following specific steps:

the first step is as follows: and (5) measuring the size of the channel steel. The channel-section steel is put into two measurement cylinders 19 with the opening state outwards, along with the feeding of channel-section steel, measurement cylinder 19 constantly rotates, and drive measurement briquetting 43 and rotate around measurement pivot 20, measurement briquetting 43 extrudes button head slider 59 in order, when the slider 59 is led to the circle overcomes the downward displacement of the elasticity of spring 62, conducting layer 60 switch-on conducting loop 61, the detection procedure has obtained the signal of telecommunication like this, along with measurement briquetting 43 rotates around measurement pivot 20, measurement briquetting 43 leaves button head slider 59, the slider 59 is led to the circle resets under the influence of the elasticity of spring 62, conducting layer 60 disconnection conducting loop 61, the detection procedure has lost the signal of telecommunication like this. Therefore, the feeding channel steel can be continuously rotated and continuously detected, a plurality of electric signals can be obtained by a detection program, and then the size of the feeding channel steel can be calculated.

The second step is that: and (5) supporting the die and clamping. After the channel steel is in place, the supporting die 16 is pushed to slide into the channel steel along the sliding rod 24 in the supporting die, the clamp motor 47 is started, the driving gear rotating shaft 50 rotates and drives the driving gear 55 and the intermediate gear 57, the intermediate gear 57 drives the driven gear 54 to rotate, the driven gear 54 and the driving gear 55 drive the screw gear 51 to rotate respectively, the screw gear 51 drives the screw 49, and the nut 52 is displaced and moves towards the middle part due to the rotation of the screw 49. The movement of nut 52 drives clamping rod 27 to swing to the outside, and the swing of clamping rod 27 drives clamping plate gear 26 to move to the both ends of rack 30, and then drives vertical clamping plate 25 to shift to the center, because vertical clamping plate 25 and horizontal clamping plate 15 fixed connection, so horizontal clamping plate 15 also shifts to the central point, finally contacts the channel-section steel and steps up the channel-section steel.

The third step: and (5) cutting a right angle. Hydraulic oil is injected from the auxiliary hydraulic cylinder process input port 41, the hydraulic oil pushes the auxiliary hydraulic cylinder piston 40 to move towards two ends of the auxiliary hydraulic cylinder 39, the original hydraulic oil in the auxiliary hydraulic cylinder 39 is pressed into the main hydraulic cylinder 29 through the main hydraulic cylinder process input port 34, the process oil path 35 and the auxiliary hydraulic cylinder return input port 36, the main hydraulic cylinder piston 31 starts to move towards the center, and as the right-angle cutter 14 is fixedly arranged on the cutter rest 13, the cutter rest 13 is fixedly arranged on the hydraulic extension rod 12, and the hydraulic extension rod 12 is fixedly arranged on the main hydraulic cylinder piston 31, the right-angle cutter 14 moves towards the center and gradually contacts and cuts off the channel steel.

A fourth step of: and (5) resetting the cutter. After the right angle shearing of the channel steel is completed, hydraulic oil enters the main hydraulic cylinder 29 from the return input port 33 of the main hydraulic cylinder, the piston 31 of the main hydraulic cylinder is pushed to move towards the direction far away from the center, the right angle cutter 14 is fixedly arranged on the cutter rest 13, the cutter rest 13 is fixedly arranged on the hydraulic extension rod 12, and the hydraulic extension rod 12 is fixedly arranged on the piston 31 of the main hydraulic cylinder, so that the right angle cutter 14 also starts to move towards the direction far away from the center, and finally the hydraulic cylinder is reset under the influence of the limit block 32 of the main hydraulic cylinder.

The fifth step: the clamp is released. The clamp motor 47 is started to rotate reversely, the driving gear rotating shaft 50 is reversely rotated and drives the driving gear 55 and the intermediate gear 57 to rotate reversely, the intermediate gear 57 drives the driven gear 54 to rotate reversely, the driven gear 54 and the driving gear 55 respectively drive the screw gear 51 to rotate reversely, the screw gear 51 drives the screw 49 to rotate reversely, and the nut 52 is displaced and moved to the two ends by the reverse movement of the screw 49. The movement of nut 52 drives the inside swing of clamping lever 27, and the swing of clamping lever 27 drives splint gear 26 to the inboard removal of rack 30, and then drives vertical splint 25 to both ends displacement, because vertical splint 25 and horizontal splint 15 fixed connection, so horizontal splint 15 also to linking a section displacement, finally loosen the channel-section steel and cancel the clamp of channel-section steel.
