Description

Technical Field

[0001] This utility model belongs to the field of steel fiber processing technology, specifically a steel fiber end deformation processing device. Background Technology

[0002] Steel fibers, as an important reinforcing material, are widely used in concrete, refractory materials, and other fields, significantly improving the tensile strength, crack resistance, and durability of these materials. Traditional steel fibers are mostly straight or simply curved, resulting in limited anchoring force in concrete and a tendency for slippage or pull-out, thus reducing the reinforcing effect. Therefore, it is necessary to bend and deform the ends of the steel fibers to improve their anchoring performance.

[0003] A search revealed a utility model patent for a bent steel fiber structure, with authorization announcement number CN219766631U and application date of May 30, 2023. The device includes a base plate, a fixing plate fixedly connected to the top surface of the base plate, a mold base fixedly connected to one side of the fixing plate, a guide box fixedly connected to the outer wall of one side of the mold base, a pressure plate provided on one side of the guide box, a shrinkage groove formed on the outer wall of the mold base, and a concave mold movably connected to the inner wall of the shrinkage groove. This device automatically arranges the steel fibers by feeding them into a feeding trough and allowing them to fall into a limiting groove. However, simply using the limiting groove is insufficient to achieve neat automatic arrangement and continuous feeding of the steel fibers, resulting in a reduced yield rate for bending the ends of the steel fibers. Furthermore, jamming and material blockage are prone to occur during the bending process, further affecting the processing efficiency of the steel fibers.

[0004] In view of this, a steel fiber end deformation processing device with efficient bending and precise material output has been developed to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing steel fiber processing devices, such as low processing efficiency and easy material blockage during actual use, the technical problem to be solved is to provide a steel fiber end deformation processing device with efficient bending and precise material discharge.

[0006] The technical solution is as follows: A steel fiber end deformation processing device includes a processing table, a side plate, an electric conveying wheel, a drive motor, and an extrusion wheel. It also includes a slitting and forming assembly and a top-feeding structure. The slitting and forming assembly is located on the side plate near the extrusion wheel. The slitting and forming assembly includes a die, a connecting seat, a positioning block, a guide post, a punch, and an elastic element. The die is located on the side plate near the extrusion wheel. A guide post is located at the top of the die. A connecting seat is slidably mounted on the guide post. A punch is located at the bottom of the connecting seat and is positioned directly above the die. A positioning block is located at the top of the connecting seat. The rotation of the extrusion wheel can compress the positioning block, causing the positioning block and the punch to move downwards. An elastic element is mounted on the guide post. The upper end of the elastic element is connected to the connecting seat, and the lower end of the elastic element is connected to the die. A top-feeding structure is located inside the die for pushing the cut and extruded steel fibers upwards.

[0007] Furthermore, the slitting and forming assembly also includes a cutter and a pad. The cutter is installed on the left side of the connecting seat, and the pad is connected to the left side of the die, with the pad located directly below the cutter.

[0008] Furthermore, the ejector structure includes a pad and a reset component. A groove is provided on the inner side of the die cavity, and a pad that can slide up and down is provided in the groove. A reset component is connected between the bottom of the pad and the bottom of the die cavity.

[0009] Furthermore, corresponding guide grooves are provided on the left and right sides of the die, and a positioning groove is provided on the top of the pad that is flush with and corresponds to the guide groove.

[0010] Furthermore, the concave mold has a left-high, right-low tilted structure design.

[0011] Furthermore, the top of the positioning block is provided with an arc-shaped groove that matches the outer edge of the extrusion wheel.

[0012] Furthermore, it also includes a limiting guide component, which includes a limiting groove plate and a guide groove plate. A set of limiting groove plates is provided in the middle of the front side of the side plate. Guide groove plates for smoothly guiding the steel fibers before processing are respectively provided on the left and right sides of the limiting groove plate, and the adjacent guide groove plates are designed in a figure-eight shape.

[0013] Furthermore, it also includes a receiving bin, which is placed on the right side of the processing table to collect the cut and extruded steel fibers.

[0014] Beneficial effects: The combination of extrusion rollers and slitting and forming components enables the simultaneous and rapid cutting of multiple steel fibers before processing and precise bending of their ends, which can significantly improve processing efficiency; the ejector structure allows the formed steel fibers to be ejected from the die quickly and smoothly, and the combination of backing plate and guide groove ensures the stability of the steel fiber discharge process after cutting and extrusion, thus effectively avoiding the clogging problems common in traditional devices.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] Example: This utility model provides a steel fiber end deformation processing device, such as... Figures 1 to 5As shown, the assembly includes a processing table 1, a side plate 2, an electric conveyor wheel 3, a drive motor 4, an extrusion wheel 5, a slitting and forming component, and an ejector structure. The processing table 1 has a side plate 2 on its upper part. One side of the side plate 2 has a set of electric conveyor wheels 3 for intermittently conveying the steel fibers a before processing. The other side of the side plate 2 has a drive motor 4 installed. The output shaft of the drive motor 4 is connected to the extrusion wheel 5. A slitting and forming component is located on the side plate 2 near the extrusion wheel 5. The slitting and forming component includes a die 6, a connecting seat 7, a positioning block 8, a guide post 9, a punch 10, and an elastic element 11. The die 6 is located on the side plate 2 near the extrusion wheel 5. The top of the die 6 has a guide post 9, and the connecting seat 7 is slidably mounted on the guide post 9. The bottom of the connecting seat 7 has a punch 10, which is located directly above the die 6. The part is provided with a positioning block 8, and the rotation of the extrusion wheel 5 can squeeze the positioning block 8, so that the positioning block 8 and the punch 10 move downward. The top of the positioning block 8 is provided with an arc groove 80 that matches the outer edge of the extrusion wheel 5, which helps to reduce the friction when the extrusion wheel 5 contacts the positioning block 8, thereby avoiding excessive wear on the outer edge of the extrusion wheel 5. An elastic element 11 is sleeved on the guide post 9, and the upper end of the elastic element 11 is connected to the connecting seat 7, and the lower end of the elastic element 11 is connected to the die 6. The elastic element 11 is a compression spring. When the edge of the extrusion wheel 5 is separated from the positioning block 8, the compression spring can drive the connecting seat 7, the positioning block 8 and the punch 10 connected to it to move upward and reset, so that the cut and extruded steel fiber b can automatically slide out and be unloaded. The inner side of the die 6 is provided with a ejector structure for pushing the cut and extruded steel fiber b upward.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, the slitting and forming assembly also includes a cutter 12 and a pad 15. The cutter 12 is installed on the left side of the connecting seat 7, and the pad 15 is connected to the left side of the die 6. The pad 15 is located directly below the cutter 12. The lower edge of the cutter 12 is lower than the lower edge of the punch 10. Thus, when the positioning block 8 and the punch 10 move downward, the cutter 12 can move downward synchronously, so that the cutter 12 can first cut the steel fiber a before processing, and then the cut steel fiber is extruded and formed by the cooperation of the punch 10.

[0024] Furthermore, such as Figure 2 and Figure 3As shown, the ejector structure includes a pad plate 13 and a reset member 14. A groove 60 is provided on the inner side of the die 6, and a pad plate 13 that can slide up and down is provided in the groove 60. The reset member 14 is connected between the bottom of the pad plate 13 and the bottom of the die 6. The reset member 14 is a compression spring, which is used to provide an upward reset force for the pad plate 13. Corresponding guide grooves 61 are provided on the left and right sides of the die 6, and the top of the pad plate 13 is provided with positioning grooves 131 that are flush with the guide grooves 61 and correspond one-to-one. This is beneficial for the stable positioning of the slit and extruded steel fibers. The die 6 has a left-high and right-low inclined structure design, which is beneficial for the automatic sliding out and unloading of the cut and extruded steel fibers b, avoiding material blockage.

[0025] Furthermore, such as Figure 1 and Figure 4 As shown, it also includes a limiting guide component, which includes a limiting groove plate 16 and a guide groove plate 17. A set of limiting groove plates 16 is provided in the middle of the front side of the side plate 2. Guide groove plates 17 are provided on the left and right sides of the limiting groove plate 16 respectively. The guide groove plates 17 are designed in a figure-eight shape, which can effectively prevent the steel fiber from deviating and ensure that it accurately enters the die 6. The adjacent guide groove plates 17 are designed in a figure-eight shape to smoothly guide the steel fiber a before processing.

[0026] In addition, such as Figure 1 and Figure 5 As shown, it also includes a receiving box 18, which is placed on the right side of the processing table 1 for collecting the cut and extruded steel fibers b.

[0027] The steel fiber a, before processing, passes sequentially between the electric conveyor wheels 3, through the limiting groove plate 16 and the guide groove plate 17, and through the die 6. The electric conveyor wheels 3 are activated to intermittently feed the steel fiber a. The electric conveyor wheels 3 are controlled by the drive motor 4 to ensure the steel fiber enters the processing area smoothly and accurately. Once the steel fiber enters the die 6, the drive motor 4 is activated to rotate the extrusion wheel 5. The outer edge of the extrusion wheel 5 mates with the arc-shaped groove 80 on the top of the positioning block 8. During rotation, it intermittently extrudes the positioning block 8 downwards, causing the connecting seat 7 and the punch 10 to move synchronously downwards along the guide post 9. The cutter 12 on the left side of the connecting seat 7 engages with the pad 15 on the left side of the die 6 to cut the steel fiber. When the punch 10 engages with the die 6, it extrudes and shapes the cut end of the steel fiber, forming the desired bent shape. The positioning groove 131 on the top of the pad 13 mates with the guide grooves on both sides of the die 6. The combination of 61 ensures the steel fiber remains stable during cutting and extrusion molding, and provides a buffering and protective effect, which helps improve the yield of steel fiber end bending. When the outer edge of the extrusion roller 5 disengages from the positioning block 8, the elastic force of the reset member 14 will drive the pad 13 on it to return to its original position, so that the cut and extruded steel fiber b is pushed upward. Since the die 6 is tilted with the left side higher than the right side, the cut and extruded steel fiber b can automatically slide into the receiving box 18, which can effectively prevent the cut and extruded steel fiber b from getting stuck during the discharge process.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
