The utility model is suitable for a large -scale cold heading machine has the duplicate protection function of mechanical type protection and the protection of electric formula, ensures to maintain operating personnel and operates at the machine internal security.

Description

Cold-heading protecting switch mechanism

Technical field

This utility model is related to a kind of cold headers and in particular to a kind of protection switch mechanism of large-scale cold headers.

Background technology

Cold headers be a kind of the various metal wire rods handled well are cut off and cold extrusion, make metal wire rod in mould The equipment of cold-heading molding, rubs accessory for processing various standards, non-standard securing member and vapour.Larger-size cold-heading is produced Product, being also sized to of cold headers be made very big, for large-scale cold headers, in more mold exchange or when being keeped in repair, maintenance operation people Inside member's machine to be entered into, that is, in the space between cold-heading owner slide unit and bed die case, and at this moment, machine there may be exception Operating, main slide unit also likely to be present skidding, therefore operator caused with great potential safety hazard.

Utility model content

In view of background technology exist deficiency, the purpose of this utility model be intended to provide one kind be applied to large-scale cold-heading Machine, has the double protection functions of mechanical type protection and electric protection it is ensured that maintenance operation personnel grasp in machine internal security The cold-heading protecting switch mechanism making.

This utility model to be implemented by following technical solution：

Cold-heading protecting switch mechanism it is characterised in that：Including the safety pin being connected together and safety switch key, Corresponding with safety pin, the relevant position of the main slide unit pressing plate of cold headers offers pin hole, during safety pin insertion pin hole Block the main slide unit reach retreating to rear dead point, corresponding with safety switch key, the electric control box of cold headers is provided with key and inserts Hole, when safety switch key inserts key hole, the drive control circuit of cold headers just can turn on.

After technique scheme, this utility model has mechanical type protection and the duplicate protection work(of electric protection Can be it is ensured that maintenance operation personnel operate in machine internal security, operation principle is：After shutdown, main slide unit is retreated to rear dead point, will Safety pin inserts pin hole, and safety pin blocks main slide unit, prevents machine from extremely operating or skidding, meanwhile, because peace Full switch key and safety pin connect together, and therefore can prevent other human users' electric control boxes away from electric control box And start equipment.

Brief description

This utility model has drawings described below：

Fig. 1 is scheme of installation on cold headers for this utility model.

Fig. 2 is the partial enlarged drawing of Fig. 1.

Specific embodiment

As illustrated, cold-heading protecting switch mechanism of the present utility model, including the safety by being connected together with rope Latch 1 and safety switch key 2, corresponding with safety pin 1, the relevant position of the main slide unit pressing plate 5 of cold headers offers latch Hole 6, safety pin 1 blocks when inserting pin hole 6 and retreats to the main slide unit 7 at rear dead point and move forward, corresponding with safety switch key 2, cold The electric control box 3 of upsetting machine is provided with key hole 4, the drive control of cold headers when safety switch key 2 inserts key hole 4 Circuit just can turn on, and shown in Fig. 1, respectively safety pin and safety switch key are in cold-heading owner's slide unit pressing plate, electrically behaviour The view of setting at control case.

Above-mentioned cold-heading protecting switch mechanism, after shutdown, main slide unit is retreated to rear dead point, safety pin is inserted latch Hole, safety pin blocks main slide unit, prevents machine from extremely operating or skidding it is ensured that reserving safety operation space 8, meanwhile, Because safety switch key and safety pin connect together, therefore safety switch key can prevent other away from electric control box Human users' electric control box and start equipment；And when starting shooting, safety pin is pulled away pin hole, then safety switch key is inserted Enter and in the key hole on electric control box, can achieve start.

Claims (1)

1. cold-heading protecting switch mechanism it is characterised in that：Including the safety pin being connected together and safety switch key, with Safety pin corresponds to, and the relevant position of the main slide unit pressing plate of cold headers offers pin hole, gear during safety pin insertion pin hole Firmly retreat to the main slide unit reach at rear dead point, corresponding with safety switch key, the electric control box of cold headers is provided with key hole, When safety switch key inserts key hole, the drive control circuit of cold headers just can turn on.
