Description

Technical Field

[0001] The utility model relates to the technical field of skin grinding devices, in particular to the technical field of rotary scale skin grinding mechanisms. Background Technique

[0002] Fasteners are mechanical parts used for fastening connections and are widely used in industries such as energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, molds, and hydraulics. They are characterized by a wide variety of product specifications, different performance uses, and a relatively high degree of standardization, serialization, and generalization.

[0003] Fasteners are usually made from fastener wire rods as raw materials and processed through a series of processes such as pickling, stretching, heading, and tail clamping. Among them, the purpose of the pickling process is to use acid solution to remove the scale and rust on the surface of steel (after the fastener wire rods are processed through welding and annealing, etc., oxidation will inevitably occur on their surfaces and affect the product quality). However, existing pickling processes and pickling devices, such as a pickling process for fastener raw materials with the publication number CN107557798A, a forming process for fasteners with the publication number CN112108837B, and a bolt wire rod pickling device with the publication number CN215560699U, often require a large amount of hydrochloric acid to be used, resulting in relatively serious pollution problems (which restricts the development of the standard parts industry).

[0004] Currently, there are also devices on the market that use a horizontal grinding wheel and a vertical grinding wheel to grind the wire rods respectively, such as a scale removing device for metal wire rod surface treatment with the publication number CN211053390U. However, due to the small grinding coverage area (there are grinding dead corners) of such devices, the fastener wire rods cannot fully remove the scale through only one round of grinding. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems in the prior art and propose a rotary scale skin grinding mechanism that can perform 360-degree rotary skin grinding treatment on fastener wire rods, thus effectively avoiding the phenomenon of scale residue on the fastener wire rods and enabling the fastener wire rods to be free from secondary repeated skin grinding.

[0006] To achieve the above purpose, the utility model proposes a rotary scale skin grinding mechanism, which includes a grinding belt group, a belt body driving mechanism, a slit body driving mechanism, and a controller. The grinding belt group is composed of two relatively arranged grinding belts that form a slit. On the one hand, it is driven by the belt body driving mechanism to realize the circulation of the belt surface, and on the other hand, it is driven by the slit body driving mechanism to make the slit rotate. The controller is electrically connected to the belt body driving mechanism and the slit body driving mechanism respectively.

[0007] Preferably, the belt driving mechanism includes a rotating roller, a roller frame, a belt driving motor, a belt driving driving gear, and a belt driving driven gear. Each of the grinding belts is supported by at least two rotating rollers rotatably connected to the roller frame. A belt driving driven gear is coaxially installed on one of the rotating rollers. The belt driving driven gear meshes with the belt driving driving gear, and the belt driving driving gear is driven to rotate by the belt driving motor fixed on the roller frame.

[0008] Preferably, the belt driving mechanism further includes a base and a plug post. One end of the plug post is fixed to the roller frame, and the other end is provided with a positioning screw hole. The base is provided with a socket for the plug post to be inserted and a long groove communicating with the socket. The base and the plug post are combined by a bolt passing through the long groove and screwed into the positioning screw hole.

[0009] Preferably, the seam driving mechanism includes a rotating cylinder, a seam driving motor, a seam driving driving gear, a seam driving driven gear, a support assembly, and a cylinder base. The rotating cylinder is indirectly connected to the cylinder base through the support assembly and is rotatable. The seam driving driven gear is sleeved outside the rotating cylinder and meshes with the seam driving driving gear. The seam driving driving gear is driven to rotate by the seam driving motor fixed on the cylinder base.

[0010] Preferably, the base is fixed in the cylindrical channel of the rotating cylinder.

[0011] Preferably, the support assembly includes a guide ring, a guide wheel, and a wheel frame. The guide ring is sleeved outside the rotating cylinder. The guide wheel is rotatably connected to the cylinder base through the wheel frame. The guide ring and the guide wheel are kept in a state where the ring surface and the wheel surface are in contact with each other under the limiting action of the limiting plate.

[0012] Preferably, the number of the guide rings is at least two and are respectively arranged on both sides of the seam driving driven gear.

[0013] The beneficial effects of the present utility model:

[0014] 1) By arranging two grinding belts oppositely to form a slit, using the belt driving mechanism to drive the two grinding belts to perform belt surface circulation respectively, and using the seam driving mechanism to make the slit rotate around the fastener wire along with the grinding belt group, during the traction of the fastener wire, the grinding belt group can be used to synchronously perform 360-degree rotary grinding treatment on the fastener wire, effectively avoiding the phenomenon of oxide skin residue on the fastener wire, so that the fastener wire does not need to be ground again repeatedly;

[0015] 2) By combining a rotating roller, a roller frame, a belt driving motor, a belt driving driving gear, a belt driving driven gear, a base, and a plug post to jointly form a belt driving mechanism, it is possible to use the rotating roller to expand the grinding belt and form a grinding section, thereby increasing the grinding area compared to traditional grinding wheels. Additionally, the width of the slit can be adjusted according to the wire diameter of the fastener wire, improving the adaptability and flexibility of the device.

[0016] 3) By combining a rotating cylinder, a slit driving motor, a slit driving driving gear, a slit driving driven gear, a support assembly, and a cylinder base to jointly form a slit driving mechanism, and using a guide ring, guide wheels, and a wheel frame as the support assembly, it is possible to achieve the self-rotation of the rotating cylinder without a central axis. This facilitates the layout of the grinding belt group and the belt driving mechanism inside the rotating cylinder, avoiding interference between components, and also facilitating the penetration of the fastener wire through the rotating cylinder.

Detailed Description of the Embodiment

[0022] Refer to Figure 1 , Figure 2 and Figure 3 , the rotary scale grinding mechanism of the present utility model includes a grinding belt group 1, a belt driving mechanism 2, a slit driving mechanism 3, and a controller. The grinding belt group 1 is composed of two oppositely arranged grinding belts that form a slit.

[0023] The belt driving mechanism 2 includes a rotating roller 21, a roller frame 22, a belt driving motor 23, a belt driving driving gear 24 and a belt driving driven gear 25. Each of the grinding belts is supported by at least two rotating rollers 21 rotatably connected to the roller frame 22. A belt driving driven gear 25 is coaxially installed on one of the rotating rollers 21. The belt driving driven gear 25 meshes with the belt driving driving gear 24. The belt driving driving gear 24 is driven by the belt driving motor 23 fixed on the roller frame 22 to rotate.

[0024] The belt driving mechanism 2 further includes a base 26 and a plug post 27. One end of the plug post 27 is fixed to the roller frame 22 and the other end is provided with a positioning screw hole. The base 26 is provided with a socket for the plug post 27 to be inserted into and a long groove 261 communicating with the socket. The base 26 and the plug post 27 are combined by a bolt passing through the long groove 261 and screwed into the positioning screw hole.

[0025] The seam driving mechanism 3 includes a rotating cylinder 31, a seam driving motor 32, a seam driving driving gear 33, a seam driving driven gear 34, a support assembly 35 and a cylinder base 36. The rotating cylinder 31 is indirectly connected to the cylinder base 36 through the support assembly 35 and is rotatable. The seam driving driven gear 34 is sleeved outside the rotating cylinder 31 and meshes with the seam driving driving gear 33. The seam driving driving gear 33 is driven by the seam driving motor 32 fixed on the cylinder base 36 to rotate.

[0026] The base 26 is fixed in the cylindrical channel of the rotating cylinder 31.

[0027] The support assembly 35 includes a guide ring 351, a guide wheel 352 and a wheel frame 353. The guide ring 351 is sleeved outside the rotating cylinder 31.

[0028] The number of the guide rings 351 is at least two and they are respectively arranged on both sides of the seam driving driven gear 34.

[0029] The working process of the utility model is as follows:

[0030] Before use, it is necessary to adjust the width of the slit according to the wire diameter of the fastener wire. Specifically, first insert the end of the plug post 27 with the positioning screw hole into the base 26 along the socket and control the insertion depth. Then, pass the screw rod of the bolt through the long groove 261 and screw it into the positioning screw hole until the base 26 and the plug post 27 are fixed together.

[0031] In use, first, let the fastener wire pass through the slit and continue to be conveyed (either manually pulled by a worker or electrically pulled by a traction device). Then, on the one hand, use the belt driving mechanism 2 to perform a belt surface cycle, and on the other hand, use the slit driving mechanism 3 to make the slit rotate around the fastener wire, so that the grinding belt group 1 performs a rotary scale grinding treatment on the fastener wire. For the belt driving mechanism 2, the belt driving motor 23 can drive the belt driving driven gear 25 to rotate through the belt driving driving gear 24, so as to drive the grinding belt sleeved outside the roller 21 to move in a cycle. For the slit driving mechanism 3, the slit driving motor 32 can drive the slit driving driven gear 34 to rotate through the slit driving driving gear 33, so that the slit rotates together with the rotating cylinder 31.
