Description

Technical Field

[0001] The utility model relates to a thread rolling machine, in particular to a material guide pipe used for feeding the thread rolling machine. Background Art

[0002] The thread rolling machine is a device used to process threads on the surface of the screw rod of the bolt. It generally includes an equipment frame, a fixed thread rolling plate fixed to the equipment frame, a movable thread rolling plate sliding on the equipment frame, a push block sliding on the equipment frame, and a drive that drives the movable thread rolling plate and the push block to move. The thread rolling machine is matched with the vibration plate for feeding, that is, a guide rail is set between the vibration plate and the thread rolling machine, and a section of the guide rail corresponding to the feed port of the thread rolling machine is horizontal. Under the action of the vibration plate, the bolt moves along the guide rail with the nut on top, and finally falls into the feed port of the thread rolling machine. The push block pushes the bolt into the movable thread rolling plate against the thread rolling machine. The movable thread rolling plate moves, moves and rotates with the bolt, passes through the fixed thread rolling plate, and after the thread rolling is completed, the bolt falls from the movable thread rolling plate. The existing method of using a guide rail to connect the thread rolling machine and the vibration plate still has the following problems: the bolt is prone to jamming and misplacement when entering the feed port of the thread rolling machine from the guide rail, thereby affecting the quality and efficiency of subsequent thread rolling.

[0027] See also Figure 1 A material guide tube for feeding a thread rolling machine comprises a tube body 1, a first connecting member 2 and a second connecting member 3.

[0028] The tube body 1 is vertical.

[0029] The first connecting member 2 is provided at the upper inlet of the pipe body 1, and is used to install the upper inlet of the pipe body 1 to the vibration plate. Specifically, a guide rail connected to each other is provided between the upper inlet of the pipe body 1 and the vibration plate, and the bolt 9 moves along the guide rail with the nut on top under the action of the vibration plate. The outer wall of the first connecting member 2 is provided with a notch 2a for the bolt 9 to enter the first connecting member 2. After the bolt 9 enters the first connecting member 2, it falls into the pipe body 1.

[0030] Optionally, the connection method between the first connecting member 2 and the upper end inlet of the tube body 1 can be: the edges of the tube body 1 and the first connecting member 2 at one end close to each other both have a first outward flange, and the two first flanges are connected to a first clamp 7, and the first clamp 7 is tightened by bolts 9 and nut fasteners.

[0031] The second connecting member 3 is disposed at the lower end outlet of the pipe body 1 and is used to install the lower end outlet of the pipe body 1 to the thread rolling machine.

[0032] Optionally, referring to the first connecting member 2 and the upper inlet of the tube body 1, the connection method of the second connecting member 3 and the lower outlet of the tube body 1 can be: the edges of the ends of the tube body 1 and the second connecting member 3 that are close to each other both have outward second flanges 3a, and second clamps 8 are connected to the two second flanges 3a.

[0033] In this way, the lowest bolt 9 in the pipe body 1 enters the feed port of the thread rolling machine from the second connecting member 3. The push block on the thread rolling machine moves to push the bolt 9 onto the movable thread rolling plate against the thread rolling machine, while blocking other bolts 9 in the pipe body 1; after the thread rolling of the bolt 9 is completed, the push block is reset, and other bolts 9 in the pipe body 1 move down together. Repeat the operation to push the bolt 9 in the pipe body 1 onto the thread rolling plate of the thread rolling machine cyclically.

[0034] See also Figure 1 and Figure 2 Optionally, the material guide tube for feeding the thread rolling machine further includes a horizontal first baffle rod 4, a horizontal second baffle rod 5 and a drive 6. The first baffle rod 4 and the second baffle rod 5 are both telescopic to the second connecting member 3, and are arranged one above and one below (the first baffle rod 4 is on the top, and the second baffle rod 5 is on the bottom), that is, through telescopic movement, the first baffle rod 4 and the second baffle rod 5 can be extended to exceed the inner wall of the second connecting member 3 or retracted to not exceed the inner wall of the second connecting member 3. The drive 6 acts on the first baffle rod 4 and the second baffle rod 5, so that the two have: a first state in which the first baffle rod 4 is extended and the second baffle rod 5 is retracted, or a second state in which the first baffle rod 4 is retracted and the second baffle rod 5 is extended.

[0035] In this way, when the first stopper 4 is retracted and the second stopper 5 is extended, the nut portion of the lowest bolt 9 in the pipe body 1 can abut against the extended portion of the second stopper 5, so that all the bolts 9 in the pipe body 1 are supported. When the first stopper 4 is extended and the second stopper 5 is retracted, the lowest bolt 9 in the pipe body 1 falls off, and the nut portion of the second lowest bolt 9 in the pipe body 1 can abut against the extended portion of the first stopper 4, so that the remaining bolts 9 in the pipe body 1 are supported. The first stopper 4 and the second stopper 5 are cyclically switched between the first state and the second state, and the bolts 9 in the pipe body 1 can be discharged one by one.

[0036] As for the drive 6, specifically, there can be two groups, which can separately control the first gear rod 4 and the second gear rod 5. Each group of the drive 6 includes an electromagnet 6b and a spring 6a. When the electromagnet 6b is powered off, the spring 6a retracts the first gear rod 4 or the second gear rod 5; when the electromagnet 6b is powered on, it attracts the first gear rod 4 or the second gear rod 5, overcomes the spring 6a, and turns the first gear rod 4 or the second gear rod 5 from retracting to extending.

[0037] It can be found that the extension and retraction of the first gear rod 4 and the second gear rod 5 are opposite. Therefore, further, the drive 6 includes a spring 6a, an electromagnet 6b and a swing arm 6c. The middle position of the swing arm 6c is hinged to the second connecting member 3, and the two ends form a groove pin pair with the first gear rod 4 and the second gear rod 5 respectively. In this way, as long as one of the first gear rod 4 and the second gear rod 5 is driven to move, the other will follow the opposite movement. The spring 6a and the electromagnet 6b act on the first gear rod 4 or the second gear rod 5, and the first gear rod 4 is used as an example for explanation. Specifically, the first gear rod 4 has a first annular stopper 4a that can be adsorbed by the electromagnet 6b on the part outside the second connecting member 3, and the second gear rod 5 has a second annular stopper 4b on the part outside the second connecting member 3; when the electromagnet 6b is powered off, under the action of the spring 6a, the first gear rod 4 retracts, and through the swing arm 6c, drives the second annular stopper 4b of the second gear rod 5 to resist the second connecting member 3, and the second gear rod 5 is extended at this time; when the electromagnet 6b is powered on, the first annular stopper 4a is adsorbed, the first gear rod 4 overcomes the spring 6a and extends, and through the swing arm 6c, drives the second gear rod 5 to retract.
