Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Fig. 2a is a schematic front view of the structure of the present invention.

Fig. 2b is a schematic plan view of the structure of the present invention.

The utility model provides a press slider two-degree prevents detection device that falls, including proximity switch support 1, proton support 2, adjustable proton 3, proximity switch 4, guide pin bushing 5 and slider connector 6.

The sliding block connector 6 is an important part of a press (shown in figure 7), a die is arranged on the lower bottom surface of a shell, a guide sleeve 5 (shown in figure 6) is connected to the press by a bolt fixing structure, and the sliding block connector 6 is restrained from moving up and down.

The proximity switch 4 is arranged on the guide sleeve 5 through the proximity switch bracket 1, and the adjustable proton 3 is arranged on the sliding block connector 6 through the proton bracket 2; the proximity switch 4 is a non-contact travel switch, can detect whether the adjustable proton 3 falls within 8mm outside the range of the top dead center, and can send a signal to control the position of a moving object when the moving object is expected to approach a certain position.

Fig. 3 is a schematic structural view of the proximity switch bracket of the present invention.

The proximity switch bracket 1 is a welding part, the lower end of the proximity switch bracket is provided with a round hole, the upper part of the proximity switch bracket is fixed on the lower end plane of the guide sleeve 5 through a bolt, the proximity switch 4 is arranged in the round hole, and the two ends of the proximity switch bracket are fixed through nuts.

Fig. 4 is a schematic structural diagram of the proton stent of the present invention.

The proton bracket 2 is a welding part and is fixedly arranged in an oil receiving disc 9 of the sliding block connector 6 by bolts, two small holes are pre-drilled at the L-shaped bent plate and are connected by bolts, and the adjustable proton 3 is arranged.

Fig. 5 is a schematic diagram of the structure of the adjustable proton according to the present invention.

The utility model discloses a working process and theory of operation:

fig. 8a is a schematic view of the working principle of the rod system of the present invention.

Fig. 8b is a schematic view of the detection function of the present invention.

Taking four bars as an example, when the crank 7 rotates, the connecting rod 8 is driven to move, and because the connecting rod 8 is connected with the sliding block connector 6, the sliding block connector 6 moves up and down. When the crank 7 runs to the top dead center, namely the highest point, the angle of the crank 7 is set to 0 degree, and the crank is rotated clockwise by 360 degrees for one turn by taking the angle as the reference. Since the press actually stops at the highest point with errors, 360(-10, +10) is generally satisfactory. The upper and lower proximity switch detection ranges are typically selected to be 8mm, and the crank 7 is required to be rotated through an angle of about 7 degrees. That is to say, when needing to overhaul the mould, the sliding block connector 6 has been braked, stop in 360(-10, +10) scope at the top dead center, maintenance personal goes to overhaul the mould this moment, in case sliding motion has to sliding block connector 6, then probably the crank rotates clockwise 10 degrees ~ 17 degrees or anticlockwise rotates 350 degrees ~ 343 degrees within ranges, proximity switch 4 plays this moment, just can detect adjustable proton 3, the press will report to the police and in time let the bivalve stop the action this moment, press forced emergency braking, in order to make things convenient for maintenance personal to detect the trouble, fine assurance personal safety.

The utility model discloses two degrees detection device that prevents falling, when the press braking back, in case detect the slider lapse again, then can in time detect and report to the police, force press emergency braking to guarantee maintenance personal safety. The utility model discloses the form is simple, and the transmission is steady, and installation and adjustment are convenient, and are with low costs.

The above embodiments of the present invention are merely examples, not the only ones, and all changes within the scope of the present invention or the same range of the present invention are all surrounded by the present invention.
