Изобретение относитс к оборудованию дл обработки штанг и может быть использовано в промышленности т желого машиностроени дл механизированной правки пруткового проката.The invention relates to equipment for machining rods and can be used in the heavy machinery industry for mechanized straightening of bar stock.

Известно устройство дл правки раст жением деталей типа штанг, содержашее смонтированные на станине подвижную и неподвижную каретки с зажимами, каждый из которых выполнен в виде подвижных зажимных губок и жесткого упора, механизм подачи заготовок и конечные выключатели 1.A device for straightening parts such as rods is known, containing movable and stationary carriages mounted on a frame with clamps, each of which is made up of movable clamping jaws and a fixed stop, a mechanism for feeding blanks and limit switches 1.

Однако из-за отсутстви автоматического зажима данное устройство не обеспечивает механизацию процесса правки - раст жени штанг в поточно-массовом производстве, что ведет к снижению производительности.However, due to the lack of automatic clamping, this device does not mechanize the straightening process — stretching the rods in mass production, which leads to a decrease in productivity.

Цель изобретени - повышение производительности устройства путем автоматизации процесса правки заготовок.The purpose of the invention is to improve the performance of the device by automating the process of editing workpieces.

Поставленна цель достигаетс тем, что в каждом зажиме жесткий упор установлен симметрично относительно обеих зажимных губок, а неподвижна каретка снабжена пальцем, взаимодействуюшим с одним из конечных выключателей.The goal is achieved by the fact that in each clamp the fixed stop is installed symmetrically with respect to both clamping jaws, and the fixed carriage is provided with a finger interacting with one of the limit switches.

На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 - неподвижна каретка в рабочем положении, обший вид.FIG. 1 shows the proposed device, a general view; in fig. 2 - the carriage is stationary in the working position, the general view.

Устройство дл правки содержит станину 1 с установленными на ней подвижной 5 кареткой 2 и неподвижной кареткой 3 одинаковой конструкции, силовой цилиндр 4, механизм подачи заготовок в виде кантовател 5 (дл ориентации заготовки по оси кареток при подаче в устройство и дл ... удалени после правки), конечные выключатели 6 и 7 и палец 8.The dressing device comprises a frame 1 with a movable 5 carriage 2 mounted on it and a stationary carriage 3 of the same design, a power cylinder 4, a mechanism for feeding workpieces in the form of a turning device 5 (for orientation of the workpiece along the axis of the carriages when fed into the device and edits), limit switches 6 and 7 and finger 8.

Каретки 2 и 3 состо т из корпуса 9, установленного на катках 10 и имеющего вертикальный фигурный паз 11, силового цилиндра зажима 12, соединенного через J5 систему рычагов 13 с зажимными губками 14, между которыми установлен жесткий упор 15, ширина которого меньше зазора между зажимными губками 14 в их рабочем состо нии , но достаточна дл гарантированного контакта с торцом заготовки.The carriages 2 and 3 consist of a body 9 mounted on rollers 10 and having a vertical figure groove 11, a power cylinder clamp 12 connected through J5 a system of levers 13 with clamping jaws 14, between which a rigid stop 15 is installed, whose width is less than the gap between the clamp jaws 14 in their working condition, but sufficient to guarantee contact with the end of the workpiece.

Устройство дл правки работает следующим образом.The device for dressing works as follows.

Claims

From the storage magazine (not shown), the rod is fed into the device and lies on the guide angle profile of the turner 5, thereby obtaining direction along the axis of the carriages 2 and 3, which are spread so that the ends of any rod do not reach the carriages. Tilter 5 at the expense of the weight of the rod presses the spool (not shown) through which air pressure is applied to the power cylinder 4, the rod of which moves the movable carriage 2 until the fixed stop 15 does not touch the end of the rod, then the movable carriage 2 moves together with the rod, which, along the corner profile of the turn-off device 5, rests with its other end on the rigid stop 15 of the carriage 3, which, under the action of the rod resting against its rigid stop 15, transmits a force to the finger 8, which closes the circuit of the limit switch 6, while move with lovogo cylinder 4 is stopped. The rod is thus oriented precisely along the rigid stops 15 of the carriages 2 and 3, and since the stops 15 are between the clamping jaws 14, when pressure is applied to the cylinders of the clamp 12 through a system of levers 13, the rod heads are clamped strictly behind the end of the nipple. Thus, the clamp bar made in automatic mode. Next, the process of straightening the shtang is effected due to the force developed by the cylinder 4, while the stationary carriage 3 is kept from moving with a finger 8, and the carriage 2 is stretching the rod, straightening it and straightening the misalignment of the rod heads. When the carriage 3 reaches the limit switch 7, the straightening ends, the cylinders of the clamp 12 release the rod and the tilter 5 removes it from the device. The use of the proposed method allows to increase the productivity of bar editing by automating the whole process, to improve the quality of the rods, since conditions are created for editing the bar along its entire length, including its most important part - the head. In addition, by reducing the time for installing the boom into the clips, it is possible not only to correct the booms, but also to stretch them beyond the elastic limit, creating an elongation of 3–5%, without increasing the total time spent by the boom in the device. a queue gives an increase in the strength of the rod and a saving in metal (1 kg per rod), which, with a program of 300,000 rods per year, will save 60 thousand rubles. The invention of the device for straightening parts such as rods of submersible pumps, containing movable and stationary carriages mounted on the frame with clamps, each of which is made in the form of movable clamping jaws and fixed stop, a workpiece feeding mechanism and limit switches, characterized in that in order to increase productivity, in each clamp a fixed stop is installed symmetrically with respect to both clamping jaws, and the stationary carriage is provided with a finger interacting with one m of the end switches her.
