Description

Technical Field

[0001] The utility model belongs to the technical field of screws, in particular to a screw head forming device. Background Art

[0002] In the process of screw production, a punching machine is mostly used to punch the head, and then the screw is formed through the thread rolling process. However, when the screws are collected after production, they fall from the punching machine and collide with the collection guide box, making the outside of the body easily damaged, which in turn reduces the quality of the subsequent thread rolling process and leads to the risk of reduced screw production quality. For this reason, we propose a screw head forming equipment. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. This device reduces the impact force of the screws dropped from the punching car by setting a first spring and cooperating with a guide device, so that the screws will not have a large collision during the collection process, thereby improving the stability of subsequent production of the screws. The first spring is squeezed and deformed, while driving the guide device to move to reduce the impact force of the screw on the guide device. The guide device guides the screw to fall onto the transmission device placed on the lower side of the guide device for removal;

[0012] 2. The impact force generated between the screw and the guide device is reduced by setting a metal elastic tube, a metal elastic plate, and a second spring. The metal elastic plate will unload the force on the screw in advance, reduce the force on the screw, and wait for the first spring and the guide device to unload the force for the second time, thereby improving the protection stability of the device for the screw.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4, a screw heading forming equipment includes a stamping lathe 100, a blanking box 200 is fixedly connected to the front side of the stamping lathe 100, and a plurality of first springs 210 are fixedly connected to the upper side of the blanking box 200, and the blanking box 200 is covered on the outer side of the guide device 300, so that the displacement range of the blanking box 200 is controllable, and the blanking box 200 is prevented from shaking greatly, thereby increasing the impact force between the screw and the guide device 300, and the blanking box 200 is fixedly connected to the guide device 300 through the first spring 210, and the stamping lathe 100 performs stamping and heading forming on the screw, and the screw falls to the guide device 300 after the processing is completed, and the guide device 300 is hit by the screw and squeezes the first spring 210, and the first spring 210 is squeezed and deformed, and at the same time drives the guide device 300 to move to reduce the impact force of the screw on the guide device 300, and the guide device 300 guides the screw to make it fall to the transmission device placed on the lower side of the guide device 300 for removal.

[0022] The guide device 300 includes three groups of brackets 310, and the inner wall of the bracket 310 is connected to a metal elastic tube 320. The metal elastic tube 320 is provided to lower the screw and the guide device 300. The inner wall of the metal elastic tube 320 is evenly and movably connected to multiple groups of metal elastic plates 330. The lower side of the metal elastic plate 330 is fixedly connected to a second spring 340, and the lower side of the second spring 340 is movably connected to the metal elastic tube 320. When the screw dropped into the guide device 300 collides with the guide device 300, the metal elastic plate 330 collides with the screw first. Due to the limitation of the metal elastic tube 320 and the limiting plate 350, the displaceable position of the metal elastic plate 330 is limited. As a result, when the screw collides with the guide device 300, the metal elastic plate 330 will unload the force on the screw in advance to reduce the force on the screw, while waiting for the second unloading of the first spring 210 and the guide device 300, thereby improving the protection stability of the device for the screw. The material of 330 is metal wire mesh. By setting the material of the metal elastic plate 330 to be metal wire mesh, the protection performance of the device for screws is improved. Since the metal elastic plate 330 is composed of metal wire, it has the performance of reducing impact force and unloading force, thereby improving the stability of the use of the device. The inner wall of the bracket 310 is fixedly connected with multiple groups of limit plates 350, and the limit plates 350 are located on the upper side of the metal elastic plate 330. The stability of the use of the metal elastic plate 330 is improved by setting the limit plates 350, so that the swing range of the metal elastic plate 330 is limited, thereby improving the stability of unloading force during subsequent screw impact. The lower side of the bracket 310 is fixedly connected with a conveying pipe 360, and the conveying pipe 360 ​​is bent. By setting the conveying pipe 360, the device can cooperate with the transmission device to guide and transmit the screws, thereby improving the stability of screw production, avoiding the risk of large impact during the screw collection process causing a decrease in the quality of subsequent thread rolling, and improving the stability of screw production.
