Adjustable double-punch device for punching point riveting

Abstract

The invention discloses an adjustable double-punch device for punching point riveting. A punch handle (1), clamping sleeves (2) and punches (4) are included. The adjustable double-punch device is characterized in that the bottom of the punch handle (1) is movably connected with the clamping sleeves (2), the clamping sleeves (2) are detachably provided with the punches (4) and are right-angle U-shaped sleeve bodies, the punches (4) are arranged in the clamping sleeves (2) through installing pins (3), the clamping sleeves (2) can move along the side face of the punch handle (1), the two sides ofthe clamping sleeves (2) are fastened through locking bolts (5), the number of the punches (4) is two, and each punch (4) is connected through two installing pins (3). In sum, the adjustable double-punch device is simple in structure, high in quality, stable, safe, reliable, efficient, convenient to use and suitable for double-punching-point popularization and usage during riveting.

Description

technical field [0001] The invention belongs to the technical field of processing devices, and in particular relates to an adjustable double punch device for punch point riveting. Background technique [0002] Riveting processing is very important in the production process, and double-point riveting is a very common riveting processing (double-point riveting parts such as image 3 shown). In the process of punching double-point riveting, the method of single-point punching in sequence is usually used. This method has the following problems: First, the size between the two points and the overall position between the two points and the parts are guaranteed to be unstable, and the processing quality The second is that the parts are in an eccentric state during processing, so it will cause damage to the parts and is unsafe, and the safety accidents caused by the parts flying out are easy to cause; the third is that the processing efficiency is low. The above many problems serio...

Problems solved by technology

In the process of punching double-point riveting, the method of single-point punching in sequence is usually used. This method has the following problems: First, the size between the two points and the overall position between the two points and the parts are guaranteed to be unstable, and the processing quality Poor; second, because the parts are in an eccentric state during processing, it will cause damage to the parts and is unsafe, and the safety accidents are likely to be caused by parts flying out; third, the processing efficiency is low

Many of the above problems seriously affect the stamping process of double-point riveting
