Abstract

The utility model provides an electric power fitting cut-out press's hole device that takes off, including the piercing press, the piercing press includes the punch die on fixed lower part's hole mould and upper portion, and the peripheral cover of punch die penetrates the hole device that takes off. When the punch is pressed down, the punch penetrates through the punched electric power fitting and is inserted into the punching die, and the hole removing device is pressed tightly; when the punching die is pulled out, if the punched hole of the electric power fitting clamps the punch, the elastic force of the hole releasing device pushes the electric power fitting to be released from the punch.

Description

Hole releasing device of electric power fitting punching die

Technical Field

The utility model relates to a stamping die technical field especially sets up a hole device takes off of electric power fitting cut-out press.

Background

According to the definition of GB/T5075-2001 national standard 'electric power noun term': an electric power fitting is a metal accessory which is used for connecting and combining various devices in an electric power system and plays a role in transmitting mechanical load, electrical load and certain protection. Hardware can be roughly classified into the following categories 1), suspension hardware, also called support hardware or suspension clamp. The hardware fitting is mainly used for hanging a lead insulator string (mostly used for a linear tower) and hanging a jumper wire on the insulator string. 2) And an anchoring hardware fitting, also called a fastening hardware fitting or a wire-resisting clamp. The hardware fitting is mainly used for fastening the terminal of a lead to be fixed on a wire-resistant insulator string and is also used for fixing the terminal of a lightning conductor and anchoring a stay wire. The anchor hardware bears all the tension of the conducting wire and the lightning conductor, and some anchor hardware becomes the conductor 3) and the connecting hardware, which are also called as wire hanging parts. The hardware fitting is used for connecting insulators into a string and connecting the hardware fitting and the hardware fitting. It is subjected to mechanical loads. 4) And connecting the hardware fitting. The hardware fitting is specially used for connecting various bare conductors and lightning conductors. The connection bears the same electrical load as the lead, and most of the connection hardware bears the whole tension of the lead or the lightning conductor. 5) And a protection hardware fitting. The fitting is used for protecting wires, insulators and the like, such as grading rings for protecting the insulators, heavy hammers for preventing insulator strings from being pulled out, anti-vibration hammers for preventing the wires from vibrating, wire protecting bars and the like 6) and contact fittings. The hardware fitting is used for connecting a hard bus and a soft bus with an outlet terminal of electrical equipment, connecting a T-shaped lead and a parallel connection without bearing force, and the like, wherein the connecting parts are in electrical contact. Therefore, higher conductivity and contact stability of the contact fitting are required. 7) The fixing hardware is also called power plant hardware or heavy current bus hardware. Such a fitting is used for fixing, connecting, and the like, various hard busbars or soft busbars and post insulators in a power distribution device, and most of the fixing fittings do not serve as electric conductors but merely play roles of fixing, supporting, and suspending. However, since these hardware are used for large currents, all components should have no hysteresis loss.

Many of the above fittings need to be punched, sometimes several holes need to be punched simultaneously: the punching device is characterized in that various holes are punched on materials such as a steel plate and the like to adapt to different requirements, and because steel hardware fittings are firm, when a plurality of holes are punched, a punched metal tool usually clamps a punch head, manual assistance is needed to enable the punched metal tool to be separated from the punch head, and automatic production is greatly influenced.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the above-mentioned prior art, the utility model aims at providing an electric power fitting cut-out press takes off hole device.

The purpose of the utility model is realized with the following mode:

the hole releasing device comprises a punching machine, wherein the punching machine comprises a fixed lower hole die and an upper punch die, and the periphery of a punch of the punch die is sleeved with the hole releasing device.

The hole removing device is formed by sleeving an elastic body on the periphery of the punch.

The elastomer is a high polymer elastomer comprising rubber.

And a thin steel plate is fixed on the lower surface of the elastomer, and a hole matched with the punch is formed in the thin steel plate.

When the punch is pressed down, the punch penetrates through the punched electric power fitting and is inserted into the punching die, and the elastic body is compressed; when the punching die is pulled out, if the punched hole of the electric power fitting clamps the punch, the elastic force of the elastic body pushes the electric power fitting to be separated from the punch. The thin steel plate is arranged below the elastic body, and the thickness of the thin steel plate is 0.3-0.4 mm, so that the punched hardware can be more easily separated from the punch under the condition of not influencing the elasticity of the elastic body.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Wherein 1 is a punch die, 2 is a hole die, 3 is a hole removing device, and 4 is a punch.

Detailed Description

As shown in fig. 1, the hole removing device of the electric power fitting punching die comprises a punching machine, wherein the punching machine comprises a fixed lower hole die 2 and an upper punch die 1, and a punch 4 of the punch die 1 is sleeved with an injection hole removing device 3.

The hole removing device 3 is an elastic body sleeved on the periphery of the punch.

The elastomer is a high polymer elastomer comprising rubber.

The lower surface of said elastomer is fixed with a thin steel plate (not shown) provided with holes cooperating with the punches 3.

In specific working process, the electric power fitting to be punched is placed between the punch die 1 and the hole die 2, the punch 4 impacts on the electric power fitting and penetrates through a hole in the hole die, at the moment, the hole removing device 3 on the punch die 1 is in contact with the electric power fitting and generates interaction force, the instantaneous force of the punch 4 impacting the electric power fitting is very large, so the hole removing device 3 provides the electric power fitting with very large force in the moment, the hole removing device 3 is a high-molecular elastomer comprising rubber, so the hole removing device 3 provides the electric power fitting with very large elasticity in the moment, and the electric power fitting is removed from the punch 4. The thin steel plate is arranged below the elastic body, and the thickness of the thin steel plate is 0.3-0.4 mm, so that the punched electric power fittings can be more easily separated from the punch under the condition of not influencing the elasticity of the elastic body.
