Description

Technical Field

[0001] This utility model relates to the field of cold heading machines, and in particular to an automatic cold heading machine for multi-station pin shafts. Background Technology

[0002] A cold heading machine is a forging and forming device that thickens the top of bars or wires at room temperature. It is a specialized machine used for the mass production of fasteners such as nuts and bolts, primarily through upsetting. The cold heading machine uses a cold heading method to upset the heads of bolts and screws, minimizing cutting work and directly forming them into the required shape and size. This not only saves a significant amount of material but also greatly improves production efficiency and significantly enhances the mechanical strength of the upset parts. Therefore, each branch mechanism in the cold heading machine is a crucial component. Cold heading machines have multiple processing stations, including two-die four-punch cold heading machines, three-die six-punch cold heading machines, six-die six-punch cold heading machines, five-die five-punch cold heading machines, and four-die four-punch cold heading machines.

[0003] However, current cold heading machines have some shortcomings. When the cold heading machine is in use, the external wires and bars are transported by the guide wheels on the extension frame. However, since the extension frame extends outside the cold heading machine, the exposed part of the extension frame is not protected, which can damage the guide wheels. Furthermore, when the exposed guide wheels transport the wires and bars, foreign objects are prone to getting stuck. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-station automatic cold heading machine for pins, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multi-station automatic cold heading machine with pins includes a base and a cold heading machine housing. The cold heading machine housing is fixedly installed on the upper surface of the base. A viewing cover is movably installed on the upper surface of the cold heading machine housing. A movable door is movably installed on one side surface of the cold heading machine housing. An extension frame is fixedly installed inside one side of the cold heading machine housing. Guide wheels are movably installed on the upper surface of the extension frame. Protective covers are movably installed on both sides of the extension frame. A positioning component is movably installed on the lower surface of the extension frame.

[0008] As a preferred technical solution of this application, a positioning groove is provided on the lower surface of the protective cover near both ends, and a sleeve is fixedly installed on the lower surface of the protective cover near both ends.

[0009] As a preferred technical solution of this application, the positioning component includes a handle, a positioning rod, a stop ring and a spring. The upper surface of the handle is fixedly installed with the positioning rod at the four corners, and the upper end of the positioning rod passes through the rod groove and is embedded in the positioning groove.

[0010] As a preferred technical solution of this application, a stop ring is fixedly sleeved on the surface of the positioning rod located inside the rod groove, and a spring is sleeved on the surface of the positioning rod located inside the rod groove and below the stop ring.

[0011] As a preferred technical solution of this application, the sleeve is movably fitted in the sleeve groove, and the protective cover is movably connected to the extension frame through the sleeve.

[0012] As a preferred technical solution of this application, the upper end of the spring is fixed to the stop ring, and the lower end of the spring is fixed to the lower inner surface of the rod groove.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0023] like Figure 1-5 The multi-station automatic cold heading machine includes a base 1 and a cold heading machine housing 2. The cold heading machine housing 2 is fixedly installed on the upper surface of the base 1. A viewing cover 3 is movably installed on the upper surface of the cold heading machine housing 2. A movable door 4 is movably installed on one side surface of the cold heading machine housing 2. An extension frame 5 is fixedly installed inside one side of the cold heading machine housing 2. A guide wheel 8 is movably installed on the upper surface of the extension frame 5. Protective covers 6 are movably installed on both sides of the extension frame 5. A positioning component 7 is movably installed on the lower surface of the extension frame 5.

[0024] Connecting rods 501 are fixedly installed on both sides of the extension frame 5 and below. Slots 502 are formed on the surface of the connecting rods 501 near both ends. Rod slots 503 are formed on the upper surface of the extension frame 5 near the front and rear ends. Positioning slots 601 are formed on the lower surface of the protective cover 6 near both ends. Sleeves 602 are fixedly installed on the lower surface of the protective cover 6 near both ends. The cooperation between the positioning rod 702 and the positioning slot 601 allows the protective cover 6, which is flipped over and positioned above the extension frame 5, to be positioned. The positioning component 7 includes a handle 701, a positioning rod 702, a stop ring 703, and a spring 704. The upper surface of the handle 701 is located on the four sides. A positioning rod 702 is fixedly installed at the corner. The upper end of the positioning rod 702 passes through the rod groove 503 and is embedded in the positioning groove 601. The spring 704 has an upward pushing force on the stop ring 703. The stop ring 703 is fixedly sleeved on the surface of the positioning rod 702 located inside the rod groove 503. The spring 704 is sleeved on the surface of the positioning rod 702 located inside the rod groove 503 and below the stop ring 703. The sleeve 602 is movably sleeved in the sleeve groove 502. The protective cover 6 is movably connected to the extension frame 5 through the sleeve 602. The upper end of the spring 704 is fixed to the stop ring 703, and the lower end of the spring 704 is fixed to the inner lower surface of the rod groove 503.

[0025] It should be noted that this utility model is a multi-station automatic cold heading machine with pins. During use, when the guide wheel 8 is conveying wire and bar stock, the protective cover 6 can be used to cover the guide wheel 8. This can prevent damage to the guide wheel 8 and prevent foreign objects from getting stuck in the guide wheel 8 during the conveying of wire and bar stock. When the guide wheel 8 needs to be disassembled and replaced, pull down the handle 701 of the positioning component 7 so that the upper end of the positioning rod 702 of the positioning component 7 exits from the positioning groove 601 of the protective cover 6. At this time, the protective cover 6 can be flipped down to expose the guide wheel 8. Since the spring 704 has an upward pushing force on the stop ring 703, it can keep the upper end of the positioning rod 702 embedded in the positioning groove 601. This can keep the protective cover 6 covering the guide wheel 8.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
