Description
Technical field
The utility model relates to a kind of press ram falling proof device, is used for maintenance, the debugging of forcing press.
Background technology
At present, generally adopting the anti-mode that falls of slide block both at home and abroad is to carry crash bar by operation or maintenance personal, is placed between press ram and the workbench, plays interception when the undesired whereabouts of slide block.Its inefficiency wastes time and energy.
Summary of the invention
The purpose of this utility model is to provide a kind of press ram falling proof device, it adopts the action of the anti-falling device of method control of electrical control, simple, increase work efficiency, avoid all kinds of casualty accidents that fall and to cause because of slide block in forcing press maintenance, debugging, the die change process effectively, guarantee employee's life security.
The technical solution of the utility model is achieved in that the press ram falling proof device, form by upper hanging plate assembly, following bent plate assembly, safety pin, it is characterized in that: be fixedly connected with upper hanging plate assembly, cylinder assembly and travel switch in the front and back of press crown, safety pin is connected with the cylinder rod of cylinder assembly; Be installed with bent plate assembly down in the slide block front and back; The upper hanging plate assembly is provided with two cover safety pin jacks, has two elongated slots on the following bent plate assembly, on the column of forcing press safety cock is installed.
Good effect of the present utility model is to have changed the traditional approach that operation, maintenance personal carry crashproof instrument, and operation is simple, avoids all kinds of casualty accidents that fall to causing because of slide block in forcing press maintenance, debugging, the die change process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a side structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, 2, the press ram falling proof device, form by upper hanging plate assembly 1, following bent plate assembly 3, safety pin 2, it is characterized in that: be fixedly connected with upper hanging plate assembly 1, cylinder assembly 4 and travel switch 5 in the front and back of press crown 6, safety pin 2 is connected with the cylinder rod of cylinder assembly 4; Be installed with bent plate assembly 3 down in slide block 7 front and backs; Upper hanging plate assembly 1 is provided with two cover safety pin jacks, has two elongated slots on the following bent plate assembly 3, on the column of forcing press safety cock is installed.
The length of the elongated slot on the following bent plate assembly 3 is calculated according to the adjustment amount of slide block, can guarantee to have at least a safety pin to be inserted in the groove when cylinder assembly 4 actions, and it has reduced the distance that slide block glides than single groove structure, has promoted the security of system.Its central post safety cock is a kind of short circuit plug that can carry, be inserted into during the press operate as normal in the socket connecting control loop, and control safety pin 2 rollbacks puts in place; Pull up when debugging or die change and carry, prevented people's maloperation connection control loop, cause that slide block 7 is descending, cylinder assembly 4 actions of the anti-falling device of while forcing press promote to pin slide block in the elongated slot of bent plate assembly 3 under safety pin 2 insertions.
In the forcing press control system, increase the control program of anti-falling device, with interconnected lock mutually such as the action of anti-falling device and safety cock.When the operation of forcing press or maintenance personal need enter that maintenance of equipment and mould are carried out in the press workspace or more during mold exchange, after pulling up safety cock, the solenoid control cylinder rod is released safety pin 2 locks upper hanging plate assembly 1 and following bent plate assembly 3 mutually, in the time of slide block 7 whereabouts out of control, safety pin 2 is locked between upper hanging plate assembly 1 and the following bent plate assembly 3, make that slide block 7 can not continue to glide, realization is to effective control of slide block 7 whereabouts out of control, the situation of hurting sb.'s feelings thereby anti-limited slip block 7 falls takes place, and has guaranteed operation and maintenance personal's safety.When finishing in the forcing press workspace, operation or maintenance personal safeguard or more after the work of mold exchange, plug safety cock, then magnetic valve 8 again control cylinder bar traction safety pin 2 get back to initial position, the upper hanging plate assembly 1 and the following bent plate assembly 3 of anti-falling device are thrown off mutually, slide block 7 this moment can proper motion, and forcing press can operate as normal.
2) anti-falling device electric control system of forcing press and forcing press carry out interlocked control, and the major control element is installed in the forcing press switch board, mainly is made up of following three parts:
A, safety cock control loop
The safety cock control circuit is made of the safety cock on relay, control circuit, the fuselage in the switch board, plc program several sections.
B, the anti-control circuit that falls
The anti-control circuit that falls is a Circuits System additional on the basis of safety cock control circuit, is made of magnetic valve and travel switch, PLC program several sections on relay, control circuit, the fuselage in the switch board.
C, PLC program: accept safety cock and corresponding action input signal, realize corresponding output by program.
Under the normal operating conditions, plug safety cock, control loop is connected in corresponding relay K A1 adhesive in the switch board, signals to the PLC input by KA1 simultaneously, after PLC gets this signal, magnetic valve YV1 action, the anti-safety pin that falls is return and is put in place, and collision block touches travel switch SQ1, and SQ1 sends the signal that puts in place to PLC, connect the safety return circuit program, forcing press can carry out regular event this moment.
When needs are pulled up safety cock, relay K A1 disconnects, the control loop dead electricity, after PLC obtained KA1 dead electricity signal, magnetic valve YV2 action prevented that falling safety pin 2 stretches out, collision block leaves travel switch SQ1, when stretch out put in place after collision block touch travel switch SQ2, PLC receives and just can judge that safety pin has stretched out behind the signal of SQ2 and put in place, thereby stops the action of press ram.
Forcing press is equipped with 2 magnetic valves 8, and front and back respectively have 1.Totally 4 rollbacks travel switch that puts in place before and after the forcing press, when 4 travel switches send when putting signal in place simultaneously, the motor-driven work of authorized pressure, if there is certain travel switch not put in place, PLC will send warning, prompting operation person checks whether the position of safety pin is correct; Before and after the forcing press totally 4 stretch out the travel switch that puts in place, either party does not have the travel switch sender as front and back within a certain period of time when stretching out, PLC will send warning, prompting operation person checks the safety pin position.
The anti-action that falls magnetic valve must be the most important condition at the top dead-centre of forcing press with slide block 7, and this signal is provided to PLC by electric cam or mechanical cam.
