Description

The invention relates to the processing of metals by pressure and shaping in a press cassette of a bending device and can be used in mechanical engineering, for example, in the manufacture of parts for a blade of a body P401g, as well as a wing of dumps PLE 21.411, etc.

A multi-step punching line is known, containing at least two presses installed in the technological process, a loading device, industrial robots with a mechanical arm mounted along the sides of the press, and an inter-operation conveyor.

However, this line provides stamping due to two presses installed in the technological sequence, which complicates the design and manufacturing process of parts in which there is no device for unloading cellular products (parts), which complicates the unloading of parts in an empty receiving container. These operations are performed manually, which reduces line performance.

A known installation for stamping parts from sheet blanks containing a press cassette, one of the interacting working tools, which is fixedly mounted on a bed: a loading device with conveying rods and a heating inductor located in the housing, is equipped with a device for unloading finished products from press cassette. The installation is equipped with an induction heater, however, the technological process of heating and hardening the workpieces does not provide stable strength and hardness of the finished parts, in connection with this. that billets with different temperatures for heat treatment enter the inductor, stable heating is not ensured, and the process of heat treatment and quenching is violated after bending the billet along the profile. Cooling medium is introduced into the cavity of the press cassette and the workpiece is hardened. The heating time and hardening are maintained. The full cycle of the technology is violated, the stability of heat treatment of quenching in a bulk medium in tanks is necessary, and there is no tempering. In this regard, the finished parts have deviations in hardness and strength. A known machine for stamping parts from sheet blanks is not provided with countersink.

The device for unloading finished parts is made by a complex design feature and low technological capability with low productivity and quality of parts.

The aim of the invention is to increase the productivity of manufacturing parts from sheet blanks. This goal is achieved by the fact that in the line forming parts contains a loading device with conveying rods, a heating inductor installed in the bed of the press cassette with working tools and an ejector

for cooling products and a device for unloading products from the press cassette.

The line is equipped with a means for countersinking holes made in the form of a multi-spindle head mounted

5 in front of the loading device, additional loading devices, a heating inductor and a device for unloading products from the press cassette, installed parallel to the main processing line, a cross-member mounted in the bed with the possibility of vertical movement. The bending device is made in the form of two hydraulic cylinders mounted on a cross member,

5, while the working tool is mounted on the rods of hydraulic cylinders, the tool for hardening and cooling parts is made in the form of a tank with quenching water installed in the frame under the working tool

0 and an additional hydraulic cylinder mounted on a bed between the main hydraulic cylinders with the possibility of interaction with the cross member.

The production line operates as follows.

A stack of blanks 9 is installed on the conveyor 10, then a stack of blanks 9 is fed. And placed in the loading cassette 3, using a hoist and a pneumatic cylinder 12, the gripping hooks along the guides are moved under the multi-spindle head 1, the loading device 3 for countersink holes, sequentially from multi-spindle head 1, the product is moved using a grab hook to the support cassette 6 and to the magnetic head 5. in which it is raised and lowered for movement by a transport device 4. Transporting blanks comes with rods with feed to the inductor 7 preheating and to the inductor 8 of the final heating. The loading mechanism is mounted on the bed 11, passes over the tank 15 with quenching water 30 of the installation 13, heating the inductor 8 and bending and hardening the workpieces and devices for unloading products into the container 16 along the guide trays 17.

Installation 13 for bending and tempering products is a tank 15 with cold water 30 on the portal 25 with a cross member 28 mounted hydraulic cylinders 21 are flexible with rods 29 on which are mounted flanges 23 with a working tool 26 (see Fig. 3) and mounted hydraulic cylinder perch - neither (hardening) 21 a. The hydraulic cylinders are flexible 21 and dip 21 a mounted on the cross member 28 (portal 25) to the rods 29, which are fixed to the flanges 23 of the mounted plates of the two-press cassette 26, the hydraulic cylinders 21 of the dip are supported by the beam 24 of the two rolling rods in the water 30 with a two-press cassette 26. The tip 22 fixes the course of the forming cylinder (see Fig. 3).

The bending unit 13 is mounted sequentially along the production line after the transport device 4. in the upper position of the two-press cassette 26, then in the open position, the guides pass through the cassette 26 and the finished part is pushed into the container 16 along the guiding tray 17 and serve another heated billet. Before the start of the start-up line, the conveyor 10 is loaded on the conveyor belt, the high-frequency current is started, and the Start cycle button is turned on. A pneumatic cylinder 12 with a rod and a plate with a hook captures 3 loads from the cartridge package

loading device the workpiece and moves to the multi-spindle head 1 for countersinking with a working tool the holes in the workpiece.

After countersinking with the multi-spindle head 1, the workpiece moves from the support cassette 6 to the magnetic head 5, from the upper position it is lowered down to the loading position.

The magnetic head 5 captures the workpiece and lifts up, the carriage of the transport device 4 also rises up. The magnetic head 5 (see Fig. 1) and the carriage of the transport device 4 are moved forward to an intermediate position where they are simultaneously lowered downward.

In the lower position, the magnetic head 5 unloads the workpiece onto the bracket and rises up. After that, the transport device 4 with the magnetic head 5 moves back to the loading position and the loading cycle is repeated. After loading the cassette of the support 6 of the pneumatic cylinder 12 with the rod with the gripper captures the workpiece, moves to the rear position and the cassette of the foot 9 and captures the workpiece from the countersink of the multi-spindle head 1, the pneumatic cylinder 12 with the rod moves the workpiece for the countersink from the cassette of the foot 9. Magnetic head 5 is lowered to repeat the cycle.

A workpiece is captured from the support cassette 6 and rises up B waiting for a signal to move forward. After heating the product in the pre-heating inductor 7, the time relay gives the command: to raise the carriage up, turn on the linear contactor of the final heating inductor 8 and move the transport device 4 in front with the workpiece. The rods of the transport device 4 capture previously stacked workpieces and move from the bracket to the pre-heating inductor 7, and the heated workpiece to the final heating inductor 8. The magnetic head 5 and the carriage of the transport device 4 unload the product (workpiece) when lowering respectively onto the bracket and in the inductor 7-8, the magnetic head 5 after unloading rises and the transport device 4 moves back to the loading position and the cycle repeats.

After unloading the support cassette 6, the pneumatic cylinder 12 captures the workpiece from the countersink to the support cassette 6, while the subsequent workpiece moves under the countersink of the multi-spindle head 1. The magnetic head 5 is lowered in its extreme rear position, captures

the product from the support cassette rises and the time relay gives a signal to move forward.

For the final heating of the workpiece, the workpiece has reached a predetermined temperature, the time relay gives a command to close the press cassette 26 of the bending device 13. The magnetic head 5 rises up, the transport device 4 goes back, the depress press cassette 26 of the bending device 13 goes down, and it is quenched in the sea water 30, tank 15. The quenching time of the part is controlled by a time relay. At the end of the quenching of the part, the time relay gives a command to raise the bending device 13 beasts. Then, by the command of the arenas relay, the magnetic head 5 in the rear position is lowered, grabs the workpiece from the support cassette 6, rises and waits

signal from the timer for lifting the carriage and moving the transport device. The time relay sends a command to lift the two-press cassette 26 upward bending

devices. In the upper position, the two-press cassette 26 is opened and gives permission to move the transport device 4 forward and the transport rods, with the pusher 27 push two blanks simultaneously into the guide tray 17 and the container 16.

The entire cycle of work is further repeated. The line is switched off by pressing the Stop button.

Using the invention improves productivity and KC. “The process of manufacturing parts during the shaping and heat treatment of products, for example, P401G dumps on a continuous

machine line.
