Description

1. Technical field

[0002] The invention belongs to the technical field of lock making machinery, and in particular relates to a double-sided extrusion printing machine for automatic unloading of lock bodies. (II) Background technology

[0004] Padlocks are widely used on indoor and outdoor doors. They are exquisitely made, practical and convenient, and are still loved by many customers at home and abroad. Figure 1 As shown in the figure, there are four planes among the six faces of the padlock body, and the other two are arc faces. The embossed patterns are generally on these two arc faces. The lock body is the external carrier of the lock, and the lock core and pins are installed inside the lock body. As customers have more and more diverse demands for trademarks and personalized requirements for embossed patterns, it is bound to require convenient replacement and adjustment of the embossing mold. The traditional embossing equipment is time-consuming to replace and debug the mold, which is not conducive to production. In addition, as customers have higher and higher requirements for the accuracy of the outer dimensions of the lock body in recent years, the traditional embossing process is carried out by using a large-tonnage punch press to punch up and down, so it is easy to cause the lock body to be slightly deformed after embossing. Moreover, some customers have already processed the lock core hole and the lock tongue hole before embossing. At this time, embossing will inevitably cause the lock core hole and the lock tongue hole to deform. In addition, traditional equipment can often only realize the production of one process. In this way, three devices are required to complete the blanking, front embossing and back embossing, which is inefficient, labor-intensive, and the time cost of machine maintenance and debugging is also high.

(V) Specific implementation methods

[0055] The accompanying drawings show a specific embodiment of the present invention. The embodiment includes a frame 4, a feeding part 7, a cutting part 8, a front extrusion feeding part 13, a picking part 11, a front extrusion part 9, a flipping part 12, a back extrusion feeding part 14 and a back extrusion part 10. The automatic material changing part 6 is placed on the right side of the frame 4, a fence 16 is fixed on the upper end of the frame 4, and a bottom plate 5 is fixed on the frame 4. All the above parts are fixed on the bottom plate 5. The feeding part 7 is installed at the right position behind the bottom plate 5, and the cutting part 8 is installed on its left side. The cut lock body 1 is transported to the cut lock body support plate 827 by the pulling block 933. The picking part 11 adjacent to the cutting part 8 is a T-shaped structure grabbing device, and its manipulator picking claw 1115 grabs the cut lock body 1 to the extrusion transition plate 911 of the front extrusion part 9. This extrusion transition plate 911 is located between the front extrusion feeding part 13 and the front extrusion part 9. The printing push rod 1306 on the front printing feed part 13 pushes the lock body 1 until it contacts the printing positioning baffle 914 under the printing turntable 904. During this pushing process, the printing turntable 904 will generate a rotational motion driven by the printing motor 908, thereby driving the printing die 905 installed on its circumference to rotate. To ensure that a complete product is printed, the linear speed of the printing die 905 on the circumference of the printing turntable 904 is consistent with the feed speed of the printing push rod 1306. The extrusion printing transfer cylinder 1213 arranged on the extrusion printing transfer cylinder seat 1212 of the front extrusion printing part 9 pushes the lock body 1 that has completed the front extrusion printing operation into the guide block 1211 of the flipping part 12, and the flipping gear 1204 on the outer periphery of the guide block 1211 flips 180 degrees under the drive of the flipping rack 1205. In this way, the surface of the lock body 1 in the guide block 1211 that has not been printed will face upward, and the flip limiting cylinder 1217 is arranged on the side of the guide block 1211. The reverse extrusion printing feed part 14 pushes the lock body 1 to the extrusion printing positioning baffle 914 below the reverse extrusion printing part 10. The reverse extrusion printing part 10 has the same structure as the above-mentioned front extrusion printing part 9. Under the combined action of the rotational movement of the extrusion printing turntable 904 and the linear movement of the extrusion printing push rod 1306 of the reverse extrusion printing feed part 14, the extrusion die 905 of the reverse extrusion printing part 10 extrude the pattern on the other side of the lock body 1. A discharge cylinder mounted on a discharge cylinder bracket is placed behind the printing turntable 904 of the reverse printing part 10, and the cylinder rod axis of the discharge cylinder is directly opposite to the center of the notch on the printing base 909. A discharge hopper is fixed to the other end of the reverse printing part 10. A control box 15 is installed at the rear end of the fence 16 at the upper end of the frame 4, and a control screen is installed at the front corner of the fence 16. The control screen can control the orderly movement of the above-mentioned parts, thereby completing the double-sided printing operation of the lock body 1.

An inclined surface 604 is processed on the guide column plate 602, and the function of the inclined surface 604 is to make the lock body rod 603 slide along the inclined surface 604 under the action of gravity. A plurality of lock body rods 603 are placed on the inclined surface 604, and a boss 605 is provided at the end of the inclined surface 604 of the guide column plate 602, which is used to limit the position of the lowest lock body rod 603 and support the weight of all the lock body rods 603 on the inclined surface 604 to prevent them from sliding down, each A lock body rod support block 606 is installed at the rear end of the guide column plate 602, and a notch is processed on the lock body rod support block 606. The notches of the above lock body rod support blocks 606 are aligned with each other and are in the same plane. The notch is used to place the lock body rod 603 for processing. The material of the lock body rod support block 606 adopts polytetrafluoroethylene with self-lubricating effect. In this way, when the lock body rod 603 slides in the groove, it will be more flexible and will not scratch the surface of the lock body rod 603. Three holes are also processed in each of the above-mentioned guide column plates 602, and a guide column sleeve is installed in each hole. A guide column sleeve is inserted in each guide column sleeve. The three guide columns are respectively a front upper guide column, a front lower guide column and a rear guide column.
