Description

Technical Field

[0001] The utility model belongs to the technical field of forming processing, and in particular relates to a compression nut forming device for a rotating station. Background Art

[0002] In traditional compression nut manufacturing, forming equipment is often bulky and has a single function, making it difficult to integrate directly into multi-process production lines. This limits the production line's continuous operation capacity and overall automation level, and also leads to inefficient utilization of production space and discontinuities in the production process. Furthermore, such equipment must be operated independently from other processing steps, increasing the number of material handling operations and extending the entire production cycle. Furthermore, the high energy consumption and high maintenance costs of large-scale equipment are also significant factors that restrict production efficiency and profitability.

[0003] Therefore, based on some of the above situations in the prior art, this application has been further designed and improved. Utility Model Content

[0004] In order to solve the above technical problems, the present invention solves them through the following technical solutions.

[0005] A compression nut forming device for a rotating workstation comprises a base platform on which a turntable and a forming mechanism are assembled.

[0006] The turntable is equipped with a placement seat, and the placement seat is provided with a through forming groove for placing the compression nut, and the base is provided with a forming seat below the forming groove. The forming seat plays a role of support and auxiliary shaping during the compression nut forming process, which helps to maintain the uniformity and consistency of the shape of the compression nut and improves the quality of the finished product. The placement seat includes a fixed sleeve, a forming sleeve and a guide column. The forming sleeve can be axially slidably assembled in the turntable, and the fixed sleeve is assembled on the turntable to axially limit the forming sleeve. The guide column is fixedly assembled with the turntable, and the forming sleeve is slidably connected to the guide column. The forming groove can accurately position the compression nut, the axial limiting cooperation between the fixed sleeve and the forming sleeve, and the sliding connection design between the forming sleeve and the guide column can ensure the smoothness and repeatability of the action during the forming process, and can avoid the turntable from being damaged by pressure, thereby extending the service life of the equipment.

[0007] The forming mechanism includes a forming mounting frame, on which a forming cylinder is mounted, which is connected to a forming head for extruding and forming the compression nut. The forming mechanism and the placement seat can accelerate the forming cycle and improve the processing efficiency of the entire production line.

[0008] As a specific embodiment of the present application, specifically, the molding groove is located in the middle of the molding sleeve, and the end face of the molding sleeve at the bottom is the first molding surface. A molding seat is provided at the corresponding molding station on the base, and the upper surface of the molding seat is the second molding surface. During the molding process, the molding head presses down the molding sleeve, and the molding head, molding groove, first molding surface and second molding surface cooperate to perform extrusion molding on the compression nut. This structural design simplifies the molding process, and the molding operation of the compression nut can be completed by directly pressing down the molding head, reducing the multi-step adjustment and positioning time that may be required in the traditional molding process, thereby improving production efficiency. And because the molding seat is fixed to the corresponding molding station of the base, the molding sleeve can be quickly replaced and the height of the molding seat can be adjusted according to the specifications of different compression nuts, which enhances the adaptability of the equipment to different product sizes and shapes and reduces the cost and time of mold replacement.

[0009] As a specific embodiment of the present application, specifically, the molding mechanism also includes a stripping cylinder, which is connected to a stripping piece. After the molding process is completed, the stripping cylinder drives the stripping piece to press against the molding sleeve to help the molding head to separate from the compression nut. The design of the stripping cylinder can effectively reduce the adhesion between the molding head and the compression nut, ensuring that the molding head can be smoothly and quickly separated from the molded compression nut, avoiding damage to the compression nut, such as pulling marks or deformation, thereby improving demoulding efficiency and product quality. Compared with simple manual or mechanical pushing methods, it is more gentle and precisely controlled, greatly reducing the risk of accidental damage to the compression nut during the demoulding process, reducing the scrap rate, and improving production efficiency and economic benefits.

[0010] Compared with the prior art, the present invention has the following beneficial effects: the forming device is miniaturized so that it can be seamlessly integrated into a multi-step processing system, which promotes the compactness and integration of the production process and significantly improves production efficiency, flexibility and economy.

[0032] Reference Figures 1 to 11 A compression nut forming machine includes a base 100, on which a turntable 120 is mounted. A feeding station, a forming station, a tapping station, and a blanking station are sequentially arranged around the turntable 120. The feeding station, the forming station, the tapping station, and the blanking station are respectively provided with a feeding mechanism 200, a forming mechanism 300, a tapping mechanism 400, and a blanking mechanism 500. The base 100 is provided with a feed tray 110 on one side of the feeding station, and a letter rolling mechanism 600 is provided between the feed tray 110 and the feeding station. The compression nut fed from the feed tray 110 is subjected to letter rolling processing by the letter rolling mechanism 600, and then passes through the turntable 120 in sequence through the feeding station, the forming station, the tapping station, and the blanking station to complete the forming and tapping processing. The turntable 120 is equipped with a plurality of placement seats 130 , each of which is provided with a through-molded groove 134 for placing a compression nut.

[0033] The specific structure of the character rolling mechanism 600 is as follows: it includes a character rolling mounting frame 610, mounted with a positioning seat 620, which is provided with a bearing slot for supporting a compression nut. A character rolling block 630 is mounted above the character rolling mounting frame 610. The character rolling block 630 is driven by a character rolling cylinder 640 and moves in a direction tangential to the outer diameter of the compression nut located in the bearing slot.

[0034] Specifically, the roller mounting frame 610 is equipped with a first positioning member 650 and a second positioning member 660 on both axial sides of the bearing groove, respectively. The first positioning member 650 and the second positioning member 660 each include a positioning cylinder 661, and the positioning cylinder 661 is connected to a positioning head 662. The end of the positioning head 662 is rotatable. The first positioning member 650 and the second positioning member 660 cooperate to axially position the compression nut. One side of the bearing groove is a slope. The feed tray 110 is connected to the bearing groove and is located on the higher side of the slope. A feed ramp 670 is provided at the lower part of the slope. The feed ramp 670 is connected to the feeding station. The feed ramp 670 is a torsion structure. The torsion structure is configured such that the compression nut enters the feed ramp 670 by contacting the bottom surface of the slope with its outer peripheral surface and leaves the feed ramp 670 by contacting the bottom surface of the feed ramp 670 with its axial end surface.

[0035] The feed tray 110 transports the compression nut to the loading slot. The first and second positioning members 650 and 660 cooperate to push the compression nut onto the ramp. The smooth movement of the roller block 630 along a linear path causes the compression nut to rotate. Simultaneously, the text pattern engraved on the roller block 630 applies uniform pressure to the outer circumference of the compression nut, forming indentations of the text. The roller block 630 retracts, and the first and second positioning members 650 and 660 retract. The compression nut, due to gravity, rolls onto the feed ramp 670. Due to the torsional structure of the feed ramp 670, upon leaving the feed ramp 670, the compression nut falls to the loading station with its axis perpendicular to the horizontal plane.

[0036] The feed mechanism 200 has the following specific structure: it includes a feed mounting frame 210, mounted with a slideway 220. A feed cylinder 230 is mounted at one end of the slideway 220, with the other end of the slideway 220 facing the turntable 120. The feed cylinder 230 is connected to a slider 240, which is provided with a receiving slot 241 for accommodating a compression nut. After the compression nut enters the receiving slot 241, the feed cylinder 230 pushes the compression nut into the forming slot 134 of the placement seat 130 located at the feed station.

[0037] In addition, the feed mounting frame 210 is also equipped with a positioning cylinder 250, which is connected to a positioning head 260. The positioning head 260 is used to position the compression nut entering the forming groove 134. The base 100 is provided with an arc-shaped abutment plate 140 along the rotation path from the feed station to the placement seat at the forming station. The abutment plate 140 is located below the forming groove 134 to prevent the compression nut from falling out of the forming groove 134 during positioning and to enable the compression nut to move smoothly from the feed station to the forming station.

[0038] The specific structure of the molding mechanism 300 is as follows: it includes a molding mounting frame 310, on which a molding cylinder 320 is mounted. The molding cylinder 320 is connected to a molding head 330, and the molding head 330 is used to extrude and mold the compression nut.

[0039] In the present application, the placement seat 130 includes a fixed cover 131, a forming sleeve 132, and a guide post 133. The forming sleeve 132 can be axially slidably assembled within the turntable 120. The fixed cover 131 is assembled on the turntable 120 to axially limit the forming sleeve 132. The guide post 133 is fixedly assembled with the turntable 120, and the forming sleeve 132 is slidably connected to the guide post 133. The guide post 133 is a guide structure with an elastic reset function (for example, a spring is assembled on the guide post 133) to help the forming sleeve 132 reset after the forming process. The forming groove 134 is located in the middle of the forming sleeve 132, and the end surface of the forming sleeve 132 at the bottom is the first forming surface 135. A forming seat 360 is provided on the base 100 corresponding to the forming station, and the upper surface of the forming seat 360 is the second forming surface 361. During the molding process, the molding head 330 presses down the molding sleeve 132 , and the molding head 330 , the molding groove 134 , the first molding surface 135 and the second molding surface 361 cooperate to perform extrusion molding on the compression nut.

[0040] To prevent the compression nut from getting stuck on the forming head 330 after the forming process is completed, the forming mechanism 300 further includes a stripping cylinder 340 connected to a stripping member 350. After the forming process is completed, the stripping cylinder 340 drives the stripping member 350 to press against the forming sleeve 132 to help the forming head 330 separate from the compression nut.

[0041] The tapping mechanism 400 is specifically structured as follows: it includes a tapping mounting frame 410, mounted with a tapping motor 420. The tapping motor 420 is connected to a tap 430 for tapping a compression nut. The base 100 is provided with a stopper cylinder 440 directly below the tap 430. The stopper cylinder 440 is connected to a stopper plate 450, which abuts the compression nut during tapping to prevent it from falling.

[0042] The specific structure of the blanking mechanism 500 is as follows: it includes a blanking mounting frame 510, mounted with a blanking cylinder 520, which is connected to a blanking head 530. The blanking mounting frame 510 is equipped with a blanking tube 540 directly below the blanking head 530, and a blanking channel 550 is provided on the base 100. During blanking, the blanking head 530 pushes the compression nut out of the molding groove 134, and the pushed-out compression nut passes through the blanking tube 540 and the blanking channel 550 in sequence.

[0043] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
