Abstract
The invention provides a safety door of a press machine. The safety door comprises a safety door body, two front supports arranged at the front end of the press machine and an air cylinder arranged on a cross beam of the upper side of the press machine. A connecting piece is arranged in the middle of the safety door body; a fixed support is in threaded connection with the output end of the air cylinder; the air cylinder is in bolt fit with the connecting piece through the fixed support at the front end to achieve fixation of the safety door body; sliding ways which are in sliding fit with the side faces of the safety door body are arranged at the corresponding inner sides of the front supports; a spring balancer is arranged on the cross beam of the upper side of the press machine. The output end of the spring balancer is connected with the two sides of the upper end of the safety door body. The safety door of the press machine has the beneficial effects that in the pressing process, the safety door is isolated from an operator; the phenomenon that in the descending process, an operator is crushed is avoided; the aim that when the safety door suddenly falls off, the operator is protected is achieved.
Description
Technical field
The invention belongs to press technologies field, especially relate to a kind of press safety door.
Background technology
Along with social production speed is accelerated, manufacturing equipment is to maximization, high speed, precise treatment, electronization and automation direction development.Operator's personal safety is constituted a potential crisis.Equipment, except possessing the necessary technological action of manufacturing process, also should increase safety prevention measure, effectively protects operator's personal safety.Establishing material base for implementing " safety in production " policy, in existing technology, generally can configure safety protective door in the front side of forcing press, with isolated operation personnel and die operation district.Forcing press safety door comprises the safety door body that is slidably fitted on front side of forcing press on two support columns and to be arranged on the upside of forcing press on crossbeam and the cylinder be positioned at directly over safety door body, and described cylinder is connected with safety door body.In the use procedure of reality, there is following problem in the forcing press safety door of said structure: due to prior art forcing press safety door slide up and down with static be all rely on cylinder carry out, if therefore electric crane breaks down, electric crane and safety door body are departed from, then very easily there is security incident, therefore, the security performance of the forcing press safety door of prior art is poor.
Summary of the invention
Object of the present invention, overcomes the defect of above prior art, provides the forcing press safety door that a kind of security performance is good.
Technical scheme of the present invention is: a kind of press safety door, comprise safety door body, be arranged at two fore-stocks of forcing press front end, with the cylinder being installed on crossbeam on the upside of forcing press, at the connector that described safety door body middle part is arranged, to be threaded fixed support at the output of cylinder, described cylinder is coordinated with connector bolt by the fixed support of front end and realizes and the fixing of safety door body, the slideway be slidably matched with safety door body side is provided with in the inner side that described fore-stock is corresponding, on the upside of forcing press, crossbeam place is provided with Spring balancer, described Spring balancer output is connected with both sides, safety door body upper end.
Further, safe grating is provided with described fore-stock front is corresponding.
Further, be also provided with pressure switch in described safety door body lower end, side fore-stock is provided with forcing press switch.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, operating personnel are convenient when operating pressure machine, safety, effectively can avoid the generation of accident, and can also fall suddenly at safety door is give operator protection.

10, forcing press switch
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
Shown in structural representation as of the present invention in Fig. 1, the invention discloses a kind of press safety door, comprise safety door body 1, be arranged at two fore-stocks 2 of forcing press front end, with the cylinder 3 being installed on crossbeam on the upside of forcing press, at the connector 4 that described safety door body 1 middle part is arranged, to be threaded fixed support 5 at the output of cylinder 3, described cylinder 3 is coordinated with connector 4 bolt by the fixed support 5 of front end and realizes and the fixing of safety door body 1, the slideway 6 coordinated with safety door body 1 side slip is provided with in the inner side that described fore-stock 2 is corresponding, on the upside of forcing press, crossbeam place is provided with Spring balancer 7, described Spring balancer 7 output is connected with both sides, safety door body 1 upper end.Be provided with safe grating 8 described fore-stock 2 front is corresponding.Also be provided with pressure switch 9 in described safety door body 1 lower end, side fore-stock is provided with forcing press switch 10.
The course of work of this example: when needs are suppressed product, first product is put in forcing press inside, then cylinder 3 is started, realize and the fixing of safety door body 1 because cylinder 3 to be coordinated with connector 4 bolt by the fixed support 5 of front end, so cylinder 3 drives safety door body 1 to move down, if now there are operating personnel arm to be goed deep into forcing press inside by mistake, safe grating 8 can detect and stop safety door body 1 action, at this moment need to restart forcing press could operate further, improve security performance, if routine operating pressure machine does not have misoperation, safety door body 1 normally can drop to bottom along slideway 6 and contact with pressure switch 9, because pressure switch 9 is connected with forcing press switch 10, pressure switch 9 forcing press switch 10 after pressurized is only had just to be opened, be in resting state before always, also have forcing press safety door body 1 slide up and down with static be all rely on cylinder 3 carry out, the Spring balancer 7 that cylinder 3 and safety door body 1 are connected if there is the words at this moment safety door body upper end of fracture can give safety door body 1 pulling force, held, security operations staff is protected.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
