Embodiment Construction

[0021] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0022] Refer to attached Figure 1-3 , a production process of a rivet nut on a punch press according to the present invention. After the raw material strip is processed by multiple drawing and forming processes, the width of the raw material strip is the same as the length of the rivet nut, and a The table top extends in the length direction. Therefore, when producing the rivet nut, it is necessary to cut out the distance of the width of the rivet nut in the length direction of the raw material strip. After the raw material strip is processed, the following steps are performed:

[0023] a. Put the raw material strip with the same cross-section as the rivet nut on the mold;

[0024] b. Use the driving device to move the raw material strip along the length direction of the raw material strip, so that the raw material strip ...

Abstract

The invention relates to a production process for press-riveting nuts on a punch press. The process comprises the steps that a raw material strip is sequentially punched, chamfered and cut off, and thus is processed into semi-finished nuts, and finally the semi-finished nuts are machined into the finished nuts through tapping. Through arrangement of the production process, burrs can be reduced effectively under the situation of ensuring the size, and the production efficiency and the production quality are improved; through setting of the feeding precision of a servo motor, the precision of punching, chamfering and material cutting is ensured; and through limit setting of the distance between a side face cut by a punch and a side face cut by a lower die, the burrs are reduced effectively.

Description

technical field [0001] The invention relates to the field of nuts, in particular to the technical field of nut production technology, in particular to a production technology of rivet nuts on a punching machine. Background technique [0002] Rivet nuts are widely used in large-scale equipment and various mechanical structures. There are many problems in the existing production process of rivet nuts. The original production process of rivet nuts is sawing-drilling-chamfering-tapping. In the sawing process, due to the accuracy of the sawing machine, it is difficult to guarantee the size, and burrs are prone to occur. At the same time, it will affect the subsequent drilling, resulting in eccentric drilling, low production efficiency and low quality. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a production process for a rivet nut on a punching machine, which can effectively reduce the generation of burrs while ensuring...
