Description

Technical Field

[0001] The invention relates to the technical field of thread rolling plates, in particular to a dust collecting component of a double-ended thread rolling plate. Background Art

[0002] Thread rolling is a processing method in which the blank between two washboards is rolled into a spiral groove when the two washboards make relative motion. The most common tool for thread rolling is the thread rolling machine. The thread rolling machine is a professional equipment for producing screws. The definition of thread rolling machine is a professional equipment for producing screws. There are many specifications of thread rolling machines, such as automatic thread rolling machines, flat thread rolling machines, semi-automatic thread rolling machines, fully automatic thread rolling machines, high-speed thread rolling machines, etc. Double-headed threads are also called double-headed screws, which refer to cylindrical fasteners with threads on both ends.

[0003] The thread rolling plate of the thread rolling machine acts on the bare nail, and the thread rolling process will produce a large amount of solid granular smoke. At the same time, the thread rolling die generates a lot of heat during the thread rolling process and needs to be cooled by cooling oil. The solid granular smoke is stained with cooling oil and then comes into contact with external dust, which easily causes more oil stains to adhere to the surface of the screw, affecting the factory quality of the screw.

[0036] The guide main board 15 is arranged above the thread rolling processing base 1, and a guide inclined plate 17 is fixedly provided at one end of the guide main board 15, and a guide bottom plate 18 is fixedly provided at the end of the guide inclined plate 17 away from the guide main board 15. The guide main board 15, the guide inclined plate 17 and the guide bottom plate 18 are all arranged in two groups, and a gap allowing the optical nail to move is formed between the two groups of guide main boards 15, and the head of the optical nail is retained between the two groups of guide main boards 15. In this way, when loading, it is only necessary to make the optical nail rod pass through the gap between the two groups of guide main boards 15 downward, and the end of the guide bottom plate 18 is horizontal, so the optical nail of the rear group pushes the front optical nail forward, so that the optical nail to be threaded can be as horizontal as possible for subsequent thread rolling. In order to adjust the spacing between the two groups of guide main boards 15, an extension positioning block 16 is fixedly provided at the end of the guide main board 15 away from the guide inclined plate 17, and a sliding member slidably connected to the extension positioning block 16 is arranged outside the guide main board 15. The outer wall of the guide main board 15 moves horizontally along the cavity of the supporting cross plate part 13, and a positive and negative threaded rod 14 is inserted in the cavity of the supporting cross plate part 13, and the positive and negative threaded rod 14 is meshed and connected with the two groups of guide main boards 15. One end of the positive and negative threaded rod 14 passes through the supporting cross plate part 13 and extends outward to set a turning handle. By operating the turning handle, the two groups of guide main boards 15 can be moved in relative or opposite directions, and the spacing between the two groups of guide main boards 15 can be adjusted. A top supporting block 22 is provided on the top of the supporting cross plate part 13, and a supporting block spring 23 is installed on the surface of the supporting block 22. The front end of the supporting block spring 23 is connected to a pushing plate 24, and the bottom of the pushing plate 24 is placed between the two groups of guide main boards 15. Through the elastic force of the top supporting block 22, the head of the optical nail closest to the pushing plate 24 can be driven to push forward, so that each optical nail can push each other, and the top of the pushing plate 24 adopts an inclined surface, so it is more convenient to insert the optical nail.

[0037] The side wall of the guide bottom plate 18 is fixedly provided with a reinforcement support side plate 25, and the end of the reinforcement support side plate 25 is bent upward to extend to form a connecting top block 26, and one end of the connecting top block 26 is equipped with a limit spring assembly 27; the light nail pasting plate 28 is fixedly arranged at the front end of the limit spring assembly 27; the limit spring assembly 27 is composed of three parts, one of which is a round cover, the other part is a spring in the round cover, the other end of the spring is reinforced and connected to the connecting top block 26, and the last part is a slide rod, wherein the slide rod is fixed to the round cover, and the slide rod is fixed to the round cover. The rod is slidably installed at the connecting top block 26, and the front end of the round cover is fixed to the light nail plate 28. The end face of the light nail plate 28 close to the light nail is in an arc shape. Therefore, when the thread rolling action starts, the light nail head will push the light nail plate 28, thereby contracting the spring and increasing the gap between the two groups of light nail plates 28 with spaced intervals, so that the light nail head can pass through the two groups of light nail plates 28 for subsequent thread rolling. The sliding rod can keep the light nail plate 28 horizontal, thereby improving the stability of the limit of the light nail head.

[0038] The top block 30 of the pasting plate is fixed on the top of the light nail pasting plate 28. A top block plug column 31 is slidably penetrated on the surface of the top block 30 of the pasting plate. A top block socket 32 ​​is horizontally opened on the top of the top block plug column 31. A top block cross column 33 is horizontally inserted into the top block socket 32. The end of the top block cross column 33 is connected to the light nail pressing plate 29. The lower end of the light nail pressing plate 29 is fitted with the light nail head. The top block socket 32 ​​adopts a rectangular opening shape. The front end of the top block cross column 33 is provided with a threaded portion. The bottom of the light nail pressing plate 29 is attached to the top of the light nail. Then insert the top block cross column 33 into the top block socket 32, and expose the threaded part at the end of the top block cross column 33, reinforce it with a nut, and then adjust the position of the light nail pressure plate 29, and then lock the nut under the top block plug column 31, so that the light nail pressure plate 29 can be limited. The light nail pressure plate 29 on the other side is installed in the same way. By locating the light nail pressure plate 29 at different positions above the light nail, the light nail head can be limited, so that the light nail head can be kept in a relatively horizontal state, thereby improving the accuracy of light nail thread rolling.

[0039] A screw hole is provided at the end of the guide bottom plate 18, and a connecting screw portion 21 is spirally connected to the screw hole, and a guide dust suction plate 19 is fixed at one end of the connecting screw portion 21. The bottom of the guide dust suction plate 19 is provided with dust suction openings 20 arranged at intervals, and a connecting hose 34 is connected to one end of the guide dust suction plate 19, and the end of the connecting hose 34 is connected to the dust collecting bin 35. During the entire thread rolling process, the head of the light nail is transferred from the guide bottom plate 18 to the guide dust suction plate 19, and at the same time, an adsorption airflow is generated at the dust suction opening 20 through the air pump built into the dust collecting bin 35, so that the smoke generated by the thread rolling enters the dust collecting bin 35 along the connecting hose 34 and is collected.

[0040] The bottom of the supporting transverse plate portion 13 is fixedly provided with an extension sleeve 10, the bottom of the extension sleeve 10 is slidably sleeved with a reinforcement sleeve 9, and the bottom of the reinforcement sleeve 9 is fixedly provided with a reinforcement support rod portion 8.
