Description

I

The invention relates to devices for feeding rod material and can be used in spot welding of rebar with non-parallel longitudinal rods.

A device for feeding transverse scratchers is advantageous when welding rebar with non-parallel longitudinal rods containing a carriage with an emphasis mounted on a frame with movement and a mechanism for its movement associated with the drive of the traverse of the longitudinal reticle, 1.

However, the known device is structurally complex and is characterized by significant deviations of the lengths of the transverse rods due to inevitable distances due to the presence of a large number of kinematic connections.

The aim of the invention is to simplify the design of the device.

This goal is achieved by the fact that the mechanism of movement of the carriage with an emphasis is made in the form of a guide, rigidly connected with the crosshead of the longitudinal feed of the grid and located

gvz relative to it at an angle, adjustable in accordance with the given position of the non-parallel longitudinal rod, and the rod, installed with the possibility of reciprocating postuttelnogo movement along the guide, while the carriage with an emphasis mounted on the rod with the possibility of a fixed position.

The drawing shows a kinematic scheme

this device.

The device contains traverse 2 of the longitudinal feed of the grid mounted on the frame I of the welding machine, movable carriage 3 and traverse 4 mounted on the rails 5. Traverse 4 is equipped with a gripper 6 and is connected to the pneumatic actuator 7.

The traverse 2 of the longitudinal feed of the screen is connected to the pneumatic actuator 8 and is mounted on the guides 9.

On the traverse 2, the fixed 10 and the movable 11 grippers are mounted. The carriage movement mechanism 12 is made in the form of a guide 13, rigidly connected to the crosshead 2 and located at an angle relative to it, re-7 being guided in accordance with a predetermined position of the non-parallel longitudinal rod and the staffs 14, installed with the possibility of reciprocating moved; on the direction of the yupdy 13. Kapeixa 3 is mounted on the bar 14 with a fixed positel 15. POSITION 15. The carriage .3 is equipped with a stop 16, connected to the carriage of the intermediate beam. 17. The stop 16 is fixed in the desired position 1 by the clip iS. For sections of the transverse sterilizer, but on site 19. Dp welding places will intersect and install 20 and move 21 welding heads. The stationary welding head 20 is installed on the first stage of the welding machine, the second head 21 is installed on the carriage 3. The device operates as follows. In the case of double traverse 2 in the direction of Bidi 9 B, the side of the cylinder 20 x 21 heads for: Swat1 110 and 11 feed the longitudinal rods. At the same time, the carriage 3, while the sajiaiMOM 15 of the guide -13 is clamped by the rod 14, moves along the base 1 of the welding arm Ny to the right, in the direction of feed of the transverse erase, and together with it interlace the intermediate iggang 17 and the stop 16, which limits the width of the crossbar 4. At the end of the stroke of the carriage 3, the stop 16 is fixed by the clamp 18 and the transverse rod is fed by the gripper 6, installed 5 m on the yoke 4, with a pneumatic actuator 7 in the same direction 7. When the yoke 4 reaches the stop 16, the rod is cut off with scissors 19 and the welding is made Article intersections svaroch P.1mi heads 20 and 21. The clamp 15 is then cleared state gives 14, yoke 2 vozvrshtsaets IP tsnyuch original position and is repeated. To reduce the length of the transverse rod during the return stroke of the crosspiece 2, the rod 14 is clamped by the clamp 15, the stop 16 is released a; 18 and the cycle is repeated with the above-mentioned transverse terlace feed value. Thus, automatic transverse feeding is essential; rods of variable line within the limits of a possible displacement of the kz pz of the rightmost position to the leftmost position (or vice versa). The use of this device in the case of a welder of grids will allow to automate the feeding of the transverse rods of variable depth, increase the accuracy of the length of the transverse rods and, consequently, to obtain a positive effect. The invention of the device for feeding the transverse rods, mainly when welding rebar with non-parallel longitudinal rods, containing a carriage mounted on the frame with the ability to) move 1 carriage with a stop and its movement mechanism associated with the drive of the traverse of the longitudinal feed of the grid, characterized simplifying the design, mechanism of movement of the carriage with an emphasis made in the form of a guide., rigidly connected with the cross-bar of the longitudinal feed of the grid and located at an angle to it, adjustable in accordance with the set position of the non-parallel longitudinal sterling, and the bar, installed with the BOSM1 {reciprocating reciprocating movement1 of the control, while the carriage from the elevator4 was fixed in position with the possibility of a fixed position.
