Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, especially to the technical field of a high-speed thread rolling machine. Background Art

[0002] A thread rolling machine is a device specialized for producing bolts. There are various 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. The thread rolling machine is portable, flexible, efficient and has advantages that cannot be replaced by other similar devices. The thread rolling machine avoids the limitations of lathes, drilling machines or manual tapping, saves time and effort, is not easy to have broken teeth, and the tap is not easy to break, etc. The thread rolling machine is applicable to all machinery manufacturing industries, such as machine tools, mold (factory) machinery, plastic machinery, printing machinery, packaging machinery manufacturing plants, engineering machinery, auto and motorcycle parts, aero engines, locomotives and rolling stock, tobacco machinery, and general machinery industries.

[0003] In the prior art, when a general thread rolling machine feeds materials, it is possible to feed more than one blank, which greatly affects the thread rolling effect. And generally, a thread rolling machine only has a set of thread rolling structure, and relies on a driving structure to drive a moving thread rolling plate for thread rolling, so the efficiency is limited.

[0004] To solve the problems raised in the background art, for example, the patent application No. CN202022290141.5 discloses a thread rolling machine for bolt processing, which includes a base. The top of the base is sequentially provided with a feeding structure, a thread rolling structure and two collecting boxes from top to bottom. Both the feeding structure and the thread rolling structure are inclined from top to bottom. The height of the feeding structure is higher than that of the thread rolling structure and corresponds to the thread rolling structure. The bottom of the feeding structure is provided with a driving structure. The thread rolling structure includes a feeding groove, a dividing plate and a reciprocating lead screw. The thread rolling structure includes two fixed grooves, two moving thread rolling plates and a static thread rolling plate. By relying on the inverted T-shaped feeding groove and the dividing plate, the blanks are sorted, which not only ensures that only one blank enters the thread rolling structure each time and improves the thread rolling effect, but also can send the blanks into different thread rolling pipelines. However, this device still has the following defects:

[0005] 1. Although this device sorts the blanks through the feeding groove and the dividing plate, each sorting consumes some time. Once the number of bolts to be processed is large, it is easy to affect the processing progress, thus reducing the processing efficiency;

[0006] 2. This device lacks a chip collection structure, resulting in the chips generated during the thread rolling process adhering to the thread rolling plate and the bolts, thereby affecting the processing quality. Summary of the Invention

[0007] The purpose of the present utility model is to solve the problems in the prior art, and a high-speed thread rolling machine is proposed, which can quickly process bolts, thereby improving the processing progress, and collect and process the debris generated during the processing to avoid affecting the processing quality.

[0008] To achieve the above object, the present utility model provides a high-speed thread rolling machine, including a concave support, a first mounting seat, a second mounting seat, a static thread rolling plate, a chute, a slider, a moving thread rolling plate, a pushing cylinder, a piston rod, a feeding mechanism, a vertical plate, and a chip blowing structure. The first mounting seat and the second mounting seat are symmetrically arranged above the concave support. The static thread rolling plate is installed on the inner side wall of the first mounting seat. A chute is horizontally opened on the inner side wall of the second mounting seat. A slider is slidably arranged on the chute. The side wall of the slider is connected with the moving thread rolling plate. A pushing cylinder is arranged above the concave support. The driving end of the pushing cylinder is connected with the piston rod. The end of the piston rod is connected with the rear side wall of the moving thread rolling plate. The pushing cylinder is used to drive the moving thread rolling plate to reciprocate along the chute direction. A feeding mechanism is also arranged above the concave support. The feeding mechanism is used to convey the bolts to be processed between the static thread rolling plate and the moving thread rolling plate. A vertical plate is arranged at the rear side above the concave support. The chip blowing structure is arranged on the front side wall of the vertical plate. The chip blowing structure is used to blow out the debris generated during the processing.

[0009] Preferably, the chip blowing structure includes two blowers, and the air outlets of the two blowers are both directed towards the static thread rolling plate and the moving thread rolling plate.

[0010] Preferably, baffle plates are installed on both sides above the concave support, and the baffle plates are arranged along the length direction of the concave support.

[0011] Preferably, a sliding plate is arranged on the front side wall of the concave support, the sliding plate is arranged to be inclined downward, and the inclined end of the sliding plate is connected with a support seat.

[0012] Preferably, extension plates are installed on both sides above the sliding plate. One ends of the two extension plates are both connected with the baffle plates, and the other ends of the two extension plates are commonly connected with an enclosing plate.

[0013] Preferably, two suction fans are installed on the outer side wall of the enclosing plate, two air suction openings are arranged on the inner side wall of the enclosing plate, the air suction openings are communicated with the suction fans, and the suction fans are connected with a dust collection box through pipelines.

[0014] The beneficial effects of the present utility model:

[0015] 1. By the combined use of a static thread rolling plate, a sliding groove, a sliding block, a dynamic thread rolling plate, a pushing cylinder, a piston rod, and a feeding mechanism, the utility model can quickly process each bolt. After the bolt to be processed is conveyed between the static thread rolling plate and the dynamic thread rolling plate by the feeding mechanism, the dynamic thread rolling plate can reciprocate along the direction of the sliding groove under the drive of the pushing cylinder, so that the bolt is thread rolled by the static thread rolling plate and the dynamic thread rolling plate. Since the dynamic thread rolling plate can reciprocate on the sliding groove through the sliding block, the bolt can be quickly thread rolled, thereby improving the processing progress and greatly improving the thread rolling efficiency, and solving the problem that it is easy to affect the processing progress when the number of bolts is large.

[0016] 2. By the combined use of a chip blowing structure, a chip blocking plate, an extension plate, a sliding plate, a surrounding plate, and a suction fan, the utility model can collect chips. When chips are generated during the processing of the bolt, the hair dryer and the suction fan are started by an external power supply. The hair dryer blows the chips on the thread rolling plate and drops them together with the processed bolt onto the sliding plate, and then slides to the upper part of the support seat. The chip blocking plate, the extension plate, and the surrounding plate can play a role in blocking the chips to prevent the chips from flying out. Then, the suction fan sucks the blown chips and the chips attached to the bolt into the suction port, and then discharges the chips into the dust collection box through a pipeline, thus completing the collection, which can avoid the accumulation of chips and affect the processing quality, and solves the problem that the chips generated during the thread rolling process will adhere to the thread rolling plate and the bolt, thereby affecting the processing quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Refer toFigures 1 to 4 , a high-speed thread rolling machine of the present utility model includes a concave support 1, a first mounting seat 2, a second mounting seat 3, a static thread rolling plate 4, a chute 5, a slider 6, a moving thread rolling plate 7, a pushing cylinder 8, a piston rod 9, a feeding mechanism 10, a vertical plate 11, and a chip blowing structure 12. The first mounting seat 2 and the second mounting seat 3 are symmetrically arranged above the concave support 1. The static thread rolling plate 4 is installed on the inner side wall of the first mounting seat 2. A chute 5 is horizontally opened on the inner side wall of the second mounting seat 3. A slider 6 is slidably arranged on the chute 5. The side wall of the slider 6 is connected with the moving thread rolling plate 7. A pushing cylinder 8 is arranged above the concave support 1. The driving end of the pushing cylinder 8 is connected with the piston rod 9. The end of the piston rod 9 is connected with the rear side wall of the moving thread rolling plate 7. The pushing cylinder 8 is used to drive the moving thread rolling plate 7 to reciprocate along the direction of the chute 5. A feeding mechanism 10 is also arranged above the concave support 1. The feeding mechanism 10 is used to convey the bolts to be processed between the static thread rolling plate 4 and the moving thread rolling plate 7. A vertical plate 11 is arranged at the rear side above the concave support 1. The chip blowing structure 12 is arranged on the front side wall of the vertical plate 11. The chip blowing structure 12 is used to blow out the chips generated during processing. When the bolts to be processed are conveyed between the static thread rolling plate 4 and the moving thread rolling plate 7 by the feeding mechanism 10, the moving thread rolling plate 7 can reciprocate along the direction of the chute 5 under the drive of the pushing cylinder 8, so that the bolts are subjected to thread rolling processing through the static thread rolling plate 4 and the moving thread rolling plate 7. Since the moving thread rolling plate 7 can reciprocate on the chute 5 through the slider 6, the bolts can be quickly thread rolled, thereby improving the processing progress.

[0023] Refer to Figure 2 , a high-speed thread rolling machine of the present utility model, the chip blowing structure 12 includes two blowers 122. The air outlets of the two blowers 122 are both directed towards the direction of the static thread rolling plate 4 and the moving thread rolling plate 7. By arranging two blowers 122, the chips on the static thread rolling plate 4 and the moving thread rolling plate 7 can be evenly blown off, thereby improving the processing quality.

[0024] Refer to Figure 1 , a high-speed thread rolling machine of the present utility model, baffle plates 13 are installed on both sides above the concave support 1. The baffle plates 13 are arranged along the length direction of the concave support 1. By installing the baffle plates 13, it can be avoided that the chips fall from above the concave support 1.

[0025] Refer to Figure 1 and Figure 3 , a high-speed thread rolling machine of the present utility model, a sliding plate 14 is arranged on the front side wall of the concave support 1. The sliding plate 14 is arranged to be inclined downward. The inclined end of the sliding plate 14 is connected with a support seat 15. By arranging the sliding plate 14, the processed bolts and the blown-off chips can slide onto the support seat 15 together, thereby facilitating the collection of the bolts and the chips.

[0026] Refer to Figure 3 Figure 3 , for a high-speed thread rolling machine of the present utility model, extension plates 16 are installed on both sides above the sliding plate 14. One end of each of the two extension plates 16 is connected to the chip guard plate 13, and the other ends of the two extension plates 16 are commonly connected to a surrounding plate 17. By providing the extension plates 16, it can be avoided that bolts and debris fall outwards during the sliding process, and the surrounding plate 17 can block the bolts and debris.

[0027] Refer to Figure 3 Figure 3 , for a high-speed thread rolling machine of the present utility model, two suction fans 18 are installed on the outer side wall of the surrounding plate 17, and two suction openings 19 are provided on the inner side wall of the surrounding plate 17. The suction openings 19 communicate with the suction fans 18, and the suction fans 18 are connected to a dust collection box 20 through pipes. The suction fans 18 suck the blown debris and the debris attached to the bolts into the suction openings 19 together, and then discharge the debris into the dust collection box 20 through the pipes, thereby completing the collection.

[0028] Working process of the present utility model:

[0029]

[0029] During the working process of a high-speed thread rolling machine of the present utility model, when the bolts to be processed are conveyed between the static thread rolling plate 4 and the moving thread rolling plate 7 by the feeding mechanism 10, the moving thread rolling plate 7 can reciprocate along the direction of the sliding groove 5 under the drive of the pushing cylinder 8, so that the bolts are thread-rolled by the static thread rolling plate 4 and the moving thread rolling plate 7. After the thread rolling is completed, the bolts will fall onto the sliding plate 14. At the same time, the hair dryer 122 and the suction fan 18 are started. The hair dryer 18 blows the debris on the thread rolling plates and makes it fall onto the sliding plate 14, and then slides onto the upper part of the support seat 15 together with the bolts. The chip guard plate 13, the extension plates 16 and the surrounding plate 17 can play a role in blocking the debris and prevent the debris from flying outwards. Then, the suction fan 18 sucks the blown debris and the debris attached to the bolts into the suction openings 19 together, and then discharges the debris into the dust collection box 20 through the pipes, thereby completing the collection.

[0030] The control mode of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the field, and the present utility model is mainly used to protect mechanical devices, so the control mode and wiring layout of the present utility model will not be explained in detail.
