Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution: the utility model provides a stamping die is used in processing of engine connecting piece with continuous punching press function, includes footstock 1 and base 2, installs guide arm 3 between footstock 1 and the base 2, and punching press mechanism 4 is installed to the bottom of footstock 1, and intermittent type mechanism 5 is installed at the top of footstock 1 to intermittent type mechanism 5 is connected with the transmission between punching press mechanism 4.

Specifically, punching press mechanism 4 includes two fixing bases 6, two fixing bases 6 are installed respectively and are close to the bottom of its both sides on footstock 1, all install one-way bearing 7 on two fixing bases 6, two fixing bases 6 all have pivot one 8 and pivot two 9 through one-way bearing 7 swivelling joint respectively, first gear 10 is installed to the rear end of pivot one 8, second gear 11 of being connected with first gear 10 meshing is installed to the rear end of pivot two 9, first gear 10 all articulates with second gear 11's surface has pull rod 12, the bottom of pull rod 12 articulates there is die head 13, be close to the side fixedly connected with guide pin bushing 14 at its top on the die head 13, the inner wall of guide pin bushing 14 and the outer wall sliding connection of guide rod 3, the top fixedly connected with die holder 15 of base 2.

Specifically, the intermittent mechanism 5 includes a motor 16, the motor 16 is a variable frequency motor, the motor 16 is installed at the top of the top base 1, a rocking handle 17 is installed on an output shaft of the motor 16, a guide pillar 18 is fixedly connected in front of one end of the rocking handle 17, which is far away from the motor 16, a sheave 19 is installed at the front end of the first rotating shaft 8, notches 20 are formed in the surface of the sheave 19, at least three notches 20 are provided, each notch 20 is annularly arrayed around the center of the sheave 19, the inner wall of each notch 20 abuts against the outer wall of the guide pillar 18, the motor 16 starts to drive the rocking handle 17 to rotate reversely, the sheave 19 is driven to rotate intermittently and clockwise by the abutting action of the guide pillar 18 and the sheave 20, it is worth one that four notches 20 are provided in this embodiment, that the sheave 19 rotates a circle and stops three times totally, because when the connection between the sheave 19 and the pull rod 12 rotates to the upper side, the die head 13 drives the first gear 10 to, therefore, the movement of the die head 13 is divided into three sections, the first section and the second section are ascending sections, the two ascending movement distances are consistent, the one-way bearing 7 is arranged to prevent the first section from moving back after ascending, the third section is a descending section, the descending movement distance is 2 times of that of the first section/the second section, and certain impact force needs to be kept when the die head 13 is punched, if the descending distance of the die head 13 is consistent with that of single ascending, the impact force of the die head 13 is insufficient, the raw material is punched incompletely, and the efficiency of different workers is different, so that the frequency of the motor 16 and the number of the notches 20 can be adjusted.

Specifically, a motor base 21 is mounted at the top of one side of the top base 1 close to the first rotating shaft 8, and the front end of the motor base 21 is mounted with the rear end of the motor 16.

The working principle is as follows: when the stamping die with the continuous stamping function for processing the engine connecting piece is used, firstly, a raw material plate is placed on a die holder 15 while a gap between the die head 13 and the die holder is moved up and down, then a motor 16 drives a rocking handle 17 to rotate, a grooved pulley 19 is driven to intermittently rotate through the abutting action of a guide pillar 18 and a notch 20, then a first gear 10 is driven to intermittently rotate, the die head 13 is driven to intermittently move through the meshing of the first gear 10 and a second gear 11, finally, the die head 13 is punched on the raw material plate, and after the die head 13 is moved up, the raw material is taken out; since the efficiency of different workers is also different, the presetting of the frequency of the motor 16 and the number of slots 20 can be adjusted for this purpose.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
