Detailed Description

In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step, based on the given embodiments, fall within the scope of protection of the present application.

In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

The application discloses safety device of nut forming machine, it aims at solving among the background art nut forming machine drift card dead in the time actuating mechanism continuously exerts the punching press power to very easily lead to actuating mechanism to transship and cause very big damage and if thereby the operating personnel in time discover the machine trouble and shut down the damage that causes and will be in controllable scope, but traditional nut forming machine lacks the warning link when the drift card dies actuating mechanism overload trouble appears, that is to say that operating personnel is difficult to discover the machine trouble very first time, thereby delay the shut down, cause the problem of great equipment damage, will combine the description attached drawing 1-4 to carry out detailed description below.

Example one

A safety device of a nut forming machine comprises a back punch component 20, wherein the back punch component 20 comprises a back punch seat 22, a back punch striking seat 23 and a back punch bolt 24, the back punch seat 22 is provided with a back punch striking seat installation groove 221, the back punch striking seat 23 is positioned in the back punch striking seat installation groove 221, the back punch bolt 24 is connected to an upper section 231 of the back punch striking seat, a lower section 232 of the back punch striking seat is hinged with the back punch seat 22, a locking bolt 25 penetrates through the back punch striking seat 23 and then is screwed on the back punch striking seat 22 to limit the rotation of the back punch striking seat 23 around the hinged part, and a first side surface 233 of the back punch striking seat 23 can be attached to a first plane 2211 of the back punch striking seat installation groove 221; compared with the integral type back-punch striking seat of the conventional nut forming machine, the back-punch striking seat 23 of the nut forming machine is split, each back-punch bolt 24 corresponds to one back-punch striking seat 23, one end of each back-punch striking seat 23 is hinged with the back-punch seat, and is connected to the back-punch seat through the locking bolt 24, so that the back-punch striking seat 23 is fixed on the back-punch seat, does not rotate around the hinged position of the back-punch striking seat in the normal punching process, and provides enough impact force. Therefore, the problem that once one punch breaks down, the rear impact striking seat of the whole nut forming machine is influenced when the rear impact striking seat 23 is of an integral structure in the prior art is solved.

Further, in order to facilitate the hinging of the recoil striking base 23 and the recoil base 22, in this embodiment, it is preferable that a hinge shaft installation groove 222 is formed in the recoil base 22, and the hinge shaft 223 penetrates through the recoil striking base 23 and is then fixedly arranged in the hinge shaft installation groove 222 through a bolt 2231.

In order to avoid the problem that the driving mechanism continuously applies the punching force when the punch of the nut forming machine is stuck, so that the driving mechanism is easily overloaded and greatly damaged, the embodiment is preferable, the locking bolt 25 has a reduced diameter section 251, the cross-sectional area of the reduced diameter section 251 is smaller than the cross-sectional area of the locking bolt 25, because the cross-sectional area of the reducing section is smaller than that of the locking bolt, the strength of the reducing section is smaller than that of the locking bolt, once the impact force is increased to exceed the strength of the reducing section due to the dead-locking fault of the punch end, the locking bolt 25 is broken, so that the corresponding recoil striking seat can move around the axis of the hinged position of the recoil striking seat, thereby avoiding the influence on other recoil bolts, meanwhile, the problem that the driving mechanism is overloaded to cause great damage due to the fact that the driving mechanism continuously applies stamping force when a punch of the nut forming machine is stuck is solved.

Example two

The embodiment I well solves the influence on other backward punching assemblies when the punch of the nut forming machine is stuck, and solves the problem that the driving mechanism continuously applies punching force when the punch of the nut forming machine is stuck through the fracture of the locking bolt to cause great damage due to overload of the driving mechanism, but the problem that the nut forming machine is out of order is still solved, so that for an operator, if the operator does not carefully observe, the nut forming machine is in a normal working state, but the station where the punch is stuck cannot normally produce nuts, so that the follow-up problem is caused, and the operator needs to be timely alarmed, shut down and overhaul. Therefore, the present embodiment optionally further includes a fault monitoring device 30 that is triggered when the locking bolt 25 breaks and that gives an alarm and/or controls the nut forming machine to stop.

Preferably, the fault monitoring device detects through pressure change, the detection of the pressure change is easy and simple, and the realization cost is low.

It is further preferred that the fault detection means comprises a pressure detection assembly. Specifically, the pressure detection assembly is an air pressure detection assembly, an air inflation channel 32 is formed in the rear impact seat 23, an air outlet 322 of the air inflation channel 32 is formed in the first side surface 233, the first side surface 233 of the rear impact seat 23 is attached to the first plane 2211 of the rear impact seat mounting groove to seal the air outlet 322, an inlet 321 of the air inflation channel 32 is communicated with a pressure air source, the air pressure detection assembly detects air pressure in the air inflation channel 32, so that when the impact head end is blocked, the impact force is increased to exceed the strength of the reduced diameter section, the locking bolt 25 is broken, the corresponding rear impact seat moves around the axis of the hinged part of the rear impact seat, the first side surface 233 of the rear impact seat 23 is no longer attached to the first plane 2211 of the rear impact seat mounting groove, that is, the air outlet 322 cannot be continuously sealed, the air pressure in the inflation channel will drop very rapidly and the detection of the drop in air pressure by the air pressure sensing assembly will act, including sounding an alarm and/or controlling the nut forming machine to shut down, which may be the first time the operator is disabled.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
