Description

Technical Field

[0001] This utility model relates to the field of anchor manufacturing technology, and in particular to a prestressed tendon anchor processing device. Background Technology

[0002] In prestressed engineering, prestressed tendon anchorages are the core components for achieving prestressing tension and anchorage, and are widely used in highway bridges, water conservancy and hydropower dams, tunnels, mine roofs, and other projects. Current anchorage processing mostly employs traditional techniques, specifically: round steel blanking → lathe machining → drilling → rough taper hole machining → precision reaming → chamfering → pressing holes → surface treatment. This traditional process has the following significant drawbacks: 1. Serious material waste: Iron filings generated during processing account for 35%-40% of the raw materials, resulting in extremely low raw material utilization.

[0003] 2. Complex process and low production capacity: It requires multiple traditional machine tools and multiple processes for processing. Multiple processes need to be connected in sequence, resulting in high equipment dependence and the need for a large number of manual labor collaborations. Production efficiency is limited by process bottlenecks, and the output rate of finished products is low.

[0004] 3. High cost: Different specifications of anchors require matching round steel of corresponding specifications and sizes. The larger the size of the round steel, the higher the price. Coupled with the cost of labor and material waste, the overall manufacturing cost of anchors increases, which in turn increases the project cost.

[0005] 4. Unstable quality: The quality of anchorages is easily affected by factors such as the precision of manual operation, the density of raw materials, and internal air bubbles, making it difficult to achieve uniform control. Utility Model Content

[0006] The purpose of this invention is to provide a prestressed tendon anchor processing device that can solve the problems of serious material waste, complex process, low production capacity, high cost and unstable quality in the existing anchor processing technology.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: This prestressed tendon anchor processing device includes a material rack, a shearing machine, a feeding machine, a heating furnace, and a punch press arranged in sequence; the material rack is connected to the feed inlet of the shearing machine through a conveyor roller conveyor; the feeding machine is provided with a feeding channel and a discharging channel, the feeding channel is connected to the discharging outlet of the shearing machine through a first conveyor belt, the discharging channel is connected to the feed inlet of the heating furnace through a second conveyor belt, the discharging outlet of the heating furnace is connected to one end of a third conveyor belt, and the other end of the third conveyor belt is connected to a mold set on the punch press through a slide tube; a temperature measuring instrument is provided on the third conveyor belt, a first cylinder is provided on one side of the third conveyor belt, and a slide is provided opposite on the other side; a robotic arm for moving the mold is provided next to the punch press.

[0008] A more specific technical solution in the above technical solution is: the material rack includes a base frame, and two support plates are provided on opposite sides of the top of the base frame. The height of the support plates gradually increases from one end near the conveyor roller to the other end, and a limiting block is provided on the upper surface of the support plate near the end of the conveyor roller.

[0009] Furthermore, the material rack is provided with a steel-shifting assembly at one end near the conveyor roller conveyor. The steel-shifting assembly includes a rotating shaft disposed between the two support plates, and a lever is mounted on the rotating shaft. The rotating shaft is controlled to rotate by a drive motor.

[0010] Furthermore, the second conveyor belt is equipped with a second cylinder, the cylinder body of which is mounted on a movable frame, and the piston rod of the second cylinder can extend toward the feed port of the heating furnace.

[0011] Furthermore, the feeder is a stepped feeder, with the feeding channel located at the lower part of the feeder and the discharging channel located at the upper part of the feeder.

[0012] Furthermore, the horizontal position of the slide tube near one end of the third conveyor belt is higher than that of the other end.

[0013] Furthermore, a waste collection hopper is provided at the end of the chute.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: 1. This utility model involves cutting round steel, heating it, and then transferring it to a punch press to forge it using molds of corresponding specifications. This method is completely different from the traditional anchor processing technology. After the round steel is heated at high temperature, it has strong plasticity and can be formed according to any mold. No machine tool processing is required. Very little iron filings are generated during the production process, which greatly improves the utilization rate of raw materials and reduces waste.

[0015] 2. This processing device has fewer steps, and the processing materials are automatically transferred between each step. It has a high degree of automation, saves a lot of manpower, significantly increases production capacity, and has a high finished product output rate.

[0016] 3. One specification and size of round steel can be used to meet the manufacturing needs of various specifications of anchors, reducing the types and costs of round steel procurement, while saving labor and material waste costs, and significantly reducing the overall manufacturing cost.

[0017] 4. The size and shape of the anchor are precisely controlled by the mold, avoiding human error. During the heating and forging process, the material is subjected to strong extrusion by the punch and the mold, which increases the internal density and improves the stress performance of the anchor. The quality of the finished product can be uniformly controlled. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model; however, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] like Figure 1 and Figure 2 The prestressed tendon anchor processing device shown includes a material rack 1, a shearing machine 2, a feeding machine 3, a heating furnace 4, and a punch press 5 arranged in sequence. The material rack 1 is connected to the feed inlet of the shearing machine 2 via a conveyor roller 6. The feeding machine 3 is provided with a feeding channel and a discharging channel. The feeding channel is connected to the discharge outlet of the shearing machine 2 via a first conveyor belt 7, and the discharging channel is connected to the feed inlet of the heating furnace 4 via a second conveyor belt. The discharge outlet of the heating furnace 4 is connected to one end of a third conveyor belt 8, and the other end of the third conveyor belt 8 is connected to a mold 10 set on the punch press 5 via a slide tube 9. A temperature measuring instrument 11 is provided on the third conveyor belt 8. A first cylinder is provided on one side of the third conveyor belt 8, and a slide is provided on the other side. A waste collection hopper is provided at the end of the slide. A robotic arm for moving the mold 10 is provided next to the punch press 5.

[0023] The material rack 1 includes a base frame, and two support plates 1-1 are provided on opposite sides of the top of the base frame. The height of the support plates 1-1 gradually increases from one end near the conveyor roller 6 to the other end. A limiting block 1-2 is provided on the upper surface of the support plate 1-1 near the conveyor roller 6. When the round steel 15 is placed on the support plate 1-1, it will roll towards the end near the conveyor roller 6 and be stuck by the limiting block 1-2.

[0024] The material rack 1 is equipped with a steel-pulling assembly at one end near the conveyor roller 6. The steel-pulling assembly includes a rotating shaft 12 located between two support plates 1-1. A lever 13 is mounted on the rotating shaft 12. The rotating shaft 12 is controlled to rotate by a drive motor. When the rotating shaft 12 rotates, one end of the lever 13 lifts up the round steel 15 closest to the limit block 1-2, causing it to slide onto the conveyor roller 6. Then the lever 13 resets, and subsequent round steel 15s move closer to the limit block 1-2 in sequence and are lifted up one by one by the lever 13 and slide onto the conveyor roller 6.

[0025] The second conveyor belt is equipped with a second cylinder 14. The cylinder body of the second cylinder 14 is mounted on a movable frame. The piston rod of the second cylinder 14 can extend toward the feed inlet of the heating furnace 4. The movable frame is located on one side of the second conveyor belt. When it is necessary to push the material, the movable frame drives the second cylinder 14 to move onto the second conveyor belt. The piston rod of the second cylinder 14 extends and pushes the material segment into the heating furnace 4. After the material is pushed, the movable frame drives the second cylinder 14 away from the second conveyor belt, which does not affect the conveying of subsequent material segments.

[0026] The feeder 3 is a stepped feeder, with the feeding channel located at the bottom of the feeder 3 and the discharging channel located at the top of the feeder 3.

[0027] The horizontal position of the slide tube 9 near the third conveyor belt 8 is higher than that of the other end, with a height difference of about 1 meter.

[0028] The discharge port of punch press 5 is connected to the finished product collection hopper via the fourth conveyor belt.

[0029] The processing method using the above-mentioned prestressed tendon anchor processing device includes the following steps: A. Raw material shearing: Set the shearing size in the shearing machine 2, and then the steel feeding assembly feeds the round steel 15 from the material rack 1 into the conveyor roller 6 in sequence, and transports it to the shearing machine 2 to be sheared into material segments 16; B. Automatic feeding: The material segment 16 is transported to the feeding machine 3 via the first conveyor belt 7, and then to the outside of the heating furnace 4 via the second conveyor belt. The second cylinder 14 pushes the material segment 16 from the second conveyor belt into the heating furnace 4. C. Heating treatment: Heating furnace 4 heats the material section 16 inside the furnace at a temperature of 1200℃~1280℃ for 150 seconds. After heating, the material section 16 is pushed out by the subsequent material section and falls onto the third conveyor belt 8. D. Inspection and screening: Temperature measuring instrument 11 inspects the material segment 16 on the third conveyor belt 8. Material segment 16 that does not meet the temperature requirement is pushed out of the third conveyor belt 8 by the first cylinder and falls into the waste collection hopper from the slide. Material segment 16 that meets the temperature requirement is transported to the end of the third conveyor belt 8 and enters the slide pipe 9. E. Forging and forming: The qualified material segment 16 is transported to the position of the mold 10 through the slide tube 9. The punch press 5 moves up and down and the robot moves synchronously to place the mold 10 containing the qualified material segment 16 to complete the forging and make the anchor finished product. F. Finished product collection: The finished anchorage is transported to the finished product collection hopper via the fourth conveyor belt.

[0030] The mold 10 is a customized mold that corresponds to the finished size of the anchor. The initial placement position of the mold 10 is below the slide tube 9. When the material segment 16 falls into the mold 10, the robot arm drives the mold 10 to the stamping position and drilling position of the punch press 5, so that the material segment 16 can be forged quickly.

[0031] The equipment used in this embodiment is a Q45-100 shearing machine, a YD / IGGT800kw heating furnace, and a JW31-500 punch press.

[0032] Taking the production of YJM15-4 anchorage as an example, the diameter of the round steel used for cutting is 55mm. If the traditional process is used, 1 ton of round steel can produce 0.637 tons of finished products, and about 1 ton of finished products can be produced per shift. Iron filings account for 36.3% of the raw materials, and at least 10 employees are needed per shift for production. However, if the processing device of this utility model is used, 1 ton of round steel can produce 0.954 tons of finished products, and about 23 tons of finished products can be produced per shift. Iron filings account for 4.6% of the raw materials, and only 1 employee is needed per shift for inspection.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
