Description

Crashproof signal transmitter

Technical field

The utility model relates to the extrusion press field, particularly a kind of crashproof signal transmitter, and it prevents collision equipment and possesses put in place the device of measuring ability of mould in extrusion dies automatic control transportation process.

Background technology

The developing direction of extrusion press is exactly automation, and the raising of degree of automation will improve capacity rating, the reduction working strength of workers of equipment greatly, and the automation of extrusion dies transportation is often depended in the raising of extrusion press degree of automation.Extrusion dies exists all generally in transportation that a high position is transported to low level, low level is transported to a high position; And high-order be transported to the transportation of rolling voluntarily in the chute that low level is employed in certain slope usually; Will produce huge impact at stop bit like this; And, cause certain environmental pollution with ear-piercing strike note.Behind low level, the signal that puts in place need be provided when mould in addition, realize the automation of mould operation.

Present technology is at low level rubber plate to be installed to come damping and reduce noise, installs on the chute limit as for the signal that puts in place and realizes near switch.Rubber plate damages easily, safeguards relatively difficulty; In order to satisfy mould function smoothly in chute, there are certain clearance certainly in mould and chute, and mould jumping phenomena can occur when smooth, and the signal that puts in place like this is just unstable, will cause the automation of equipment to be difficult to stable the realization.

Summary of the invention

The purpose of the utility model provides a kind of crashproof signal transmitter, and it prevents collision equipment and possess put in place the crashproof signal transmitter of measuring ability of mould, has solved the deficiency of above-mentioned present technology in extrusion dies automatic control transportation process.It is simple in structure, and is safe in utilization, reliable, stable, and it is convenient to safeguard; Slow down mould impact to equipment when a high position slips to low level; Has the measuring ability of putting in place simultaneously.

The technical scheme of the utility model is achieved in that a kind of crashproof signal transmitter of design, and it mainly comprises M body, lance, orienting sleeve, spring, connecting element, sensor, it is characterized in that: on the body M body breather hole is arranged; Orienting sleeve is fixed on the M body; It is external that the via hole that lance one end passes the M body stretches out M, and it is spacing on the end face of orienting sleeve with fastener that the other end passes the orienting sleeve inner chamber, and locate with spring cotter; Spring housing is on lance and be enclosed in the cavity that is surrounded by lance and orienting sleeve; Be fixed on the M body through support near switch.

The cavity that described breather hole one end connection lance and orienting sleeve surround, the other end penetrates the M body and is communicated with airspace.

Described breather hole diameter is chosen between the 2-5mm.

Described breather hole (9) diameter is 3mm.

The characteristics of the utility model are: under off position, lance is in the state of stretching out under the effect of spring.In working order down, mould slips row to low level from a high position, and when striking the lance left end, lance compression spring, lance move right, and spring absorbs impact, thereby the speed of buffering mould reduces noise.Receive to such an extent that mould clashes in the process that moves right at lance, the breather hole air-out on the M body, lance moves right under the combined action of impact and spring force; When breather hole is lived in the lance block; The cavity that surrounds along with lance and orienting sleeve is more and more littler, and the air in the cavity will be compressed, and lance will slowly absorb impact under spring force and air reaction combined action; Prevent the direct impact failure equipment of lance, and can reduce noise orienting sleeve.Will trigger near switch when lance moves right, the mould signal that puts in place is provided.Be applicable to the crashproof signal transmitter of extruder mold automatic transit system.

The beneficial effect of the utility model is, solved the deficiency of prior art, and is simple in structure, and it is convenient to safeguard; Slow down mould impact to equipment when a high position slips to low level; Has the measuring ability of putting in place.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1 is the structural representation of embodiment 1;

Fig. 2 is the birds-eye view of embodiment 1;

Fig. 3 is that the P of embodiment 1 is to view.

Among the figure: 1, M body; 2, lance; 3, orienting sleeve; 4, spring; 5, packing ring; 6, nut; 7, near switch; 8, support; 9, breather hole; 10, spring cotter.

The specific embodiment

Fig. 1 is the structural representation of embodiment 1.As can beappreciated from fig. 1, it mainly comprises M body 1, lance 2, orienting sleeve 3, spring 4, connecting element, sensor, on the body M body 1 breather hole 9 is arranged; Orienting sleeve 3 is fixed on the M body 1; The via hole that lance 2 one ends pass M body 1 stretches out outside the M body 1, and it is spacing on the end face of orienting sleeve 3 with fastener that the other end passes orienting sleeve 3 inner chambers, and connecting element can adopt packing ring 5, nut 6, and with spring cotter 10 location; Spring 4 is enclosed within on the lance 2 and is enclosed in the cavity that is surrounded by lance 2 and orienting sleeve 3; Sensor is fixed on the M body 1 through support 8 near switch 7.In the cavity that breather hole 9 one ends connection lance 2 and orienting sleeve 3 surround, the other end penetrates M body 1 and is communicated with airspace.

Described breather hole 9 diameters are chosen between the 2-5mm.Show that according to test data optimal selection is at 3mm.

During use: under off position, lance 2 is in the state of stretching out under the effect of spring 4.In working order down, mould slips row to low level from a high position, and when striking lance 2 left ends, lance 2 compression springs 4, lance 2 move right, and spring absorbs impact, thereby the speed of buffering mould reduces noise.Receive to such an extent that mould clashes in the process that moves right at lance 2, breather hole 9 air-outs on the M body, lance moves right under the combined action of impact and spring force; When breather hole 9 is lived in the lance block; The cavity that surrounds along with lance and orienting sleeve is more and more littler, and the air in the cavity will be compressed, and lance will slowly absorb impact under spring force and air reaction combined action; Prevent the direct impact failure equipment of lance, and can reduce noise orienting sleeve.Will trigger near switch when lance moves right, the mould signal that puts in place is provided.

The crashproof signal transmitter of the utility model design-calculated, simple in structure, it is convenient to safeguard; Slow down mould impact to equipment when a high position slips to low level; Has the measuring ability of putting in place.
