Description

Press safety cock
Technical field
The present invention relates to the technical field of safety protection of stamping equipment, and in particular to a kind of press safety cock.
Background technique
Press is widely used in auto manufacturing, when press is changed the mold, safety inspection and repair mold When equal operations, sliding block is usually parked in upper limit position, operator enters operation between sliding block and workbench, to ensure sliding block It will not fall and cause safety accident, need to prevent safety cock between sliding block and workbench, undertake the effect of safety supports.But it is old Formula steel safety bolt is more heavy, and is to fill between upper and lower mould by manpower completely, and safety cock personnel operate labor intensity Greatly, time-consuming length, and it is easy unstability, there are security risks.
Summary of the invention
Convenient, safe and reliable press safety cock is operated the object of the present invention is to provide a kind of.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of press safety cock, on the column of press It is fixedly installed support, one end of rocker arm is hinged by articulated shaft and support, and the other end of rocker arm is provided with casing, articulated shaft, Casing and column parallel arrangement, main pillar is inserted in sleeve, and when main pillar turns to working position, main pillar is in press work Make between platform and top shoe, when main pillar turns to inoperative position, main pillar, which is in, avoids position with press bed and top shoe Set place.
In above scheme, main pillar can be allowed to be in the work being supported between workbench and top shoe by rotating rocker arm Inoperative position between position and separate workbench and top shoe, it is easy to operate.
Detailed description of the invention

Enlarged diagram when Fig. 2 is working position;
Enlarged diagram when Fig. 3 is inoperative position;
Fig. 4 is enlarged schematic partial view in Fig. 2
Fig. 5 a, 5b are card column, the schematic perspective view of clip.
Specific embodiment
As Figure 1-Figure 4, a kind of press safety cock is fixedly installed support 10 on the column A of press, rocker arm 20 One end is hinged by articulated shaft 21 and support 10, and the other end of rocker arm 20 is provided with casing 22, articulated shaft 21, casing 22 and vertical Column A parallel arrangement, main pillar 30 is inserted in sleeve 22, and when main pillar 30 turns to working position, main pillar 30 is in press work Make between platform B and top shoe C, when main pillar 30 turns to inoperative position, main pillar 30 is in and press bed B and top shoe C is avoided at position.When compressor operation, rocker arm 20 drives main pillar 30 to turn to inoperative position around the rotation of articulated shaft 21, no Interfere the normal work of press;When press is changed the mold, safety inspection and when repairing the operations such as mold, rocker arm 20 around The rotation of articulated shaft 21 drive main pillar 30 to turn to working position, main pillar 30 is supported between workbench B and top shoe C, is prevented Only top shoe C falls, it is ensured that safety when operation.
Further, main pillar 30 constitutes the cooperation of moving along 22 tube core direction of casing with casing 22, covers on main pillar 30 Equipped with spring 40, spring 40, which provides elastic force, drives main pillar 30 mobile to the direction far from casing 22.At inoperative position, main branch The height outline of 30 lower end of column is higher than the height of workbench B, and pillar 30 main in this way turns to workbench B and upper cunning outside press During between block C, it will not just be interfered with workbench B, after being indexed between workbench B and top shoe C, top shoe C is pushed, and spring 40 compresses, and main pillar 30 moves down, and the lower end of main pillar 30 is against on the table, providing upward support Power, support top shoe C do not drop;After the completion of the operations such as Awaiting Overhaul, top shoe C is moved up, and main pillar 30 is not under by axial direction Pressure, the elastic force of spring 40 drive main pillar 30 to move up, and have gap between the lower end and workbench B of main pillar 30 at this time, Main pillar 30 can be turned to inoperative position in gently rotation rocker arm 20.
For the operating condition bigger for some molds, the distance between workbench B and top shoe C are small, cannot based on prop up Column 30 provides enough Support Positions, is also arranged with sleeve 51 on the main pillar 30 of 40 top of spring, the outer wall of sleeve 51 is outside It is provided with transition plates 52, the end of transition plates 52 is provided with jury strut 53, the length direction of jury strut 53 and main pillar 30 Length parallel arrangement, and the length of jury strut 53 be less than main pillar 30 length.At this point, needing first to turn to main pillar 30 Prevented setting between workbench B and top shoe C in rotation jury strut 53 close to workbench B marginal position, prevents entropy magic It falls, it is ensured that safety.
Similarly, the lower end of spring 40 is resisted against on the upper surface of casing 22, upper end is resisted against on the lower end surface of sleeve 51.Only Needing to be arranged a spring 40 can be achieved at the same time driving to main pillar 30 and jury strut 53.
When main pillar 30 is in inoperative position, it is possible that the effect by unknown external force causes main pillar 30 to turn to Working position causes the damage of mold, therefore is additionally provided with card column 23 on rocker arm 20, and clip 24 is provided on column A, and clip 24 is Section is the cuff of c-type, and when main pillar 30 is in working position, card column 23 is separated with clip 24, and main pillar 30 is in inoperative position When, card column 23 and clip 24 are clamped.Card column 23 is connected to clip 24, the position of fixed main pillar 30, when releasing clamping, with foot The external force of enough sizes pulls main pillar 30, effectively guarantees reliability when main pillar 30 is in working position.
Further, it is provided with plug 25 on rocker arm 20, the socket 26 being arranged on plug 25 and column A constitutes grafting and matches It closes, when main pillar 30 is in inoperative position, plug 25 is inserted into socket 26 and connects circuit, when main pillar 30 is in working position, inserts First 25 with separate disconnecting circuit in socket 26, the control system of the circuit and press power source is chain.Main pillar 30 is in work When position, plug 25 is extracted from socket 26, and circuit disconnects, and is fail to open by electrical interlocks circuit press, by circuit into one Step guarantees safety;When main pillar 30 is in inoperative position, plug 25 is inserted into socket 26 and connects circuit, passes through electrical interlocks circuit Press can not be normally-open.
Preferably, the buffer stopper 27 with column A cooperation is additionally provided on rocker arm 20, when main pillar 30 is in inoperative position, Buffer stopper 27 and column A are against playing the role of buffering.
Safety cock is provided with 2, and on the column A at two press diagonal positions that are placed in, and only needs on a press Want two safe bolt mechanisms.
