Problems solved by technology

[0002] Punching is an important step in the processing of the outer tube of a tubular motor. At present, when punching the outer tube of a tubular motor, multiple holes are evenly punched within the 360° circumference of the outer tube according to the requirements. First, a reference hole is punched, and then Rotate the outer tube, use the reference hole to position and punch the second hole, and then use the second hole to position and punch the third hole, and so on to complete the punching of all holes. It is necessary to manually rotate the steel pipe, and then use the mold bayonet to perform positioning and indexing , can not meet the requirements of accurate indexing processing of steel pipes, only one hole can be punched at a time, and the work efficiency is low
Therefore, the existing tubular motor outer tube punching has the disadvantages of low work efficiency and low machining accuracy

Embodiment

[0018] Embodiment: A method for punching holes in the outer tube of a tubular motor. The method adopts the downward movement of the press plate of the main shaft of the punching machine, so that the connecting rod drives the rotating mechanism to make a circular motion. The core is punched in the direction of the center of the circle to complete the punching of the outer tube of the tubular motor.

[0019] Each punch punches toward the center of the mold core under the action of the oblique arc-shaped track on the inner concave of the rotating mechanism.

[0020] The punching die for the outer pipe of the tubular motor that realizes the above method has a structure such as Figures 1 to 3 As shown, it includes the punch base 1, the punch base 1 is provided with the punch spindle pressure plate 2, the punch spindle pressure plate 2 is connected with the rotation mechanism 4 through the connecting rod 3, the rotation mechanism 4 can rotate around the punch spindle, and the rotat...

Abstract

The invention discloses a punching method of an outer tube of a tubular motor and a punching die for implementing the punching method. According to the punching method, a spindle pressure plate of a punch press is moved down so that a connecting rod drives a rotating mechanism to cycle, the rotating mechanism is used to enable multiple punches on a punch fixing block to perform central punching toward a core, and punching of the outer tube of the tubular motor is finished. The punching method has the advantages of high working efficiency and high machining precision.

Description

technical field [0001] The invention relates to a punching method for an outer tube of a tubular motor and a punching die thereof, belonging to the field of metal processing. Background technique [0002] Punching is an important step in the processing of the outer tube of a tubular motor. At present, when punching the outer tube of a tubular motor, multiple holes are evenly punched within the 360° circumference of the outer tube according to the requirements. First, a reference hole is punched, and then Rotate the outer tube, use the reference hole to position and punch the second hole, and then use the second hole to position and punch the third hole, and so on to complete the punching of all holes. It is necessary to manually rotate the steel pipe, and then use the mold bayonet to perform positioning and indexing , can not meet the accurate indexing processing requirements of steel pipes, one punching can only punch one hole, and the work efficiency is low. Therefore, th...
