Abstract

The utility model relates to a vertical safety protector for a punch press, which is composed of an infrared emitter, an infrared sensor, a solid-state voltage-stabilizing small power supply and a mechanism control part. The utility model is characterized in that the mechanical control part is a free-standing controller which is arranged on the connecting rod which is connected with the freewheel clutch of the punch press, and the mechanical control part comprises a support block, an electric magnet, a braking movable element, a chasis, a toothed rack, etc. The braking movable element is effectively sprung out by a spring depending on the power failure of a relay, the movement of a punching head is controlled, and the protective function is performed.

Description

The vertical safety guard that is used for punch press

The design belongs to field of machine tool equipment, specially refers to the safety guard of punch press.

In machining equipment, be ten parts of important things to the protection of human body safety, in various machine operations; the accident rate of operating punch machine is the highest, and unless you give your whole attention to it, or the action of floor push is in a flash inharmonic slightly; just finger or arm might be cut off, cause operator's lifelong disability.Mould in the operation of machine tool at metal-working press or filling, all often do not avoid the generation of accident.

People for seeking a kind of safety device effort, multiple design or patented technology have occurred for a long time up to now, original lathe is reequiped, but there are many disadvantages in this repacking, need the dismounting main frame, complex procedures, and expensive price should not be promoted.I once designed a kind of wheeled controller and carried out safeguard protection to punch press; the patent No. is 94213309.9; a kind of wheeled controller of chain being controlled by the special son of living is described; it can make clutch decontrol; the control drift does not descend, but the structure of wheeled controller remains more complicated.

The purpose of this utility model designs a practical and reliable punching machine safety device exactly.

The design finishes by following technical proposals, by infrared transmitter [1], infrared remote receiver [2], in the running system that solid-state voltage stabilizing small power supply [3] and mechanical control part branch constitute, its characteristics are that mechanical control section is a vertical controller [4], device is on the connecting rod that joins with the punch press flywheel clutch, vertical controller comprises supports piece [4.1], electromagnet [4.2], it is placed on supports the piece middle part, the sub-chassis [4.3] of living is subjected to electromagnet adsorbed, there is spring [4.5] inside of sub-sleeve alive [4.4], play the part of braking action and live sub [4.6] for braking, it is linked to be an integral body with the sub-chassis of living, and tooth bar [4.7] is enclosed within to be supported in the piece hole.

Device is connected with relay in the infrared system at the electromagnet [4.2] at vertical controll block middle part, and during relay power, electromagnet sucks work sub-chassis [4.3].

Vertical controller is supported the spring [4.5] in the sub-sleeve alive in the piece in the device, is placed on loosely in the sub-sleeve alive, and during the relay outage, son [4.6] ejection of can effectively braking being lived makes the sub-head of living block tooth bar [4.7].It can't be turned round, thereby clutch unclamps, no longer drive the drift motion, make the person be able to safeguard protection.

Accompanying drawings embodiment, description of drawings:

Fig. 1 is the working state schematic representation of the vertical safety guard of punch press;

Fig. 2 is infrared transmitter and infrared remote receiver outline drawing;

Fig. 3 is vertical controller architecture figure.

Wherein, the infrared transmitter [1] of plastic casing is housed, that matches with it and use is contained in The infrared remote receiver of plastic casing [2], it also comprises dress 1400 type relays within it; Gu Attitude voltage stabilizing small power supply [3] is (220V/12V) standard component; Vertical controller [4], it is one Individual assembly comprises and supports piece [4.1], is installed in the electromagnet [4.2] of core, with The electromagnetism iron phase is inhaled the sub-chassis of work [4.3] together, the sub-sleeve [4.4] of living, and spring [4.5], Braking is lived sub [4.6], and is enclosed within the tooth bar [4.7] of supporting in the piece hole, and its both sides are fixed Supporting on the piece; Whole assembly is installed on the connecting rod [5] with dynamic clutch; They also connect Follow flywheel [6], drift [7], clutch [8]; The foot of connecting rod [5] is connected to foot-operated opening Moving plate [9].

When staff is strayed into punch press lower time, infrared launcher just makes pedal quit work, and plays Safeguard protection effect, the advantage of this device be, and be simple in structure, easy to operate, the retardation efficiency height, Safe and reliable and cheap.

Most preferred embodiment has produced vertical control device, can be effectively by the motion of clutch brake punch press.In the made vertical controller, the subdivision of living material is the heat treated CT12 steel alloy of process, and spring diameter is 80, the spring external diameter is 6mm, and the sub-sleeve internal diameter of living is 6.5mm, this vertical controller is installed after, guaranteed operator's safety, its social benefit is significant.

Claims

1; the vertical safety guard that is used for punch press; by infrared transmitter [1]; infrared remote receiver [2]; solid-state voltage stabilizing small power supply [3] and mechanical control section are formed; it is characterized in that; the machinery control section is a vertical controller [4], and device is on the connecting rod that joins with the punch press flywheel clutch, and vertical controller comprises supports piece [4.1]; electromagnet [4.2]; it is placed on supports the piece middle part, and the sub-chassis [4.3] of living is subjected to electromagnet adsorbed, the sub-sleeve [4.4] of living; there is spring [4.5] its inside; play the part of braking action and live sub [4.6] for braking, it is linked to be an integral body with the sub-chassis of living, and tooth bar [4.7] is enclosed within to be supported in the piece hole.

According to the described vertical safety guard of claim 1, it is characterized in that 2, device is electrically connected with relay in the infrared system at the electromagnet [4.2] of supporting the piece middle part, during relay power, electromagnet sucks work sub-chassis [4.3].
