Description

Technical Field

[0001] The present invention relates to the technical field of upsetting equipment, and particularly to upsetting equipment for processing metal steel bars. Background Art

[0002] After retrieval, a Chinese patent discloses a patent document with the application number 201910120657.4 and the name of "Fully Automatic Upsetting Equipment and System". In this patent, a feeding mechanism transports the workpieces to be upset processed into the accommodation groove group, and then a conveying mechanism conveys the workpieces in the accommodation groove group to a heating mechanism. After the heating mechanism heats the two end parts of the workpieces, they are conveyed to a stamping mechanism, and the stamping mechanism stamps and upsets the heated ends. In order to realize the upset processing of multiple workpieces simultaneously, this patent can convey multiple workpieces at one time by setting multiple clamping manipulators. However, if we really want to realize the simultaneous processing of multiple workpieces, we also need to be equipped with a heating mechanism that matches the number of manipulators. Whether we increase the manipulators or the heating mechanism, it will undoubtedly increase the manufacturing and maintenance costs of the entire equipment. Moreover, in this patent, the heating mechanism is arranged at the stamping mechanism. Before the workpieces are upset, they need to be heated, and the waiting time for the heating treatment will also affect the forming time of the entire processing of the steel bars, reducing the production and processing efficiency of the steel bars.

[0013] Compared with the prior art, the present invention provides a heading device for processing metal steel bars, which has the following beneficial effects:

[0014] (1) The present invention reasonably arranges the storage bin and the stamping mechanism. The storage bin is arranged at the feeding end of the stamping mechanism, and then the feeding plate moves horizontally towards the stamping mechanism. When the feeding plate passes through the storage bin, the steel bars inside directly fall into the three material receiving grooves on the feeding plate. Through one-time feeding of the feeding plate, multiple steel bars can be fed. Compared with setting multiple manipulators in the prior art, setting material receiving grooves on the feeding plate can greatly reduce the manufacturing and maintenance costs of the entire device.

[0015] (2) The present invention directly sets the resistance wires for heating the steel bars inside the storage bin. The resistance wires complete all heating processes before feeding, avoiding the heating waiting time before heading the steel bars, thereby shortening the heading processing time of the steel bars as a whole and improving the production and processing efficiency.

[0016] (3) During the process of the feeding plate returning to the initial position after feeding, the stop block on the sliding plate contacts and is blocked by the storage bin. At this time, the sliding plate remains stationary and moves towards the side of the material receiving groove relative to the rectangular groove. The steel bars inside the storage bin are blocked by the sliding plate and will not fall into the material receiving groove, ensuring that they continue to be heated inside the storage bin and avoiding heat loss caused by the steel bars entering the material receiving groove prematurely. When the sliding column slides to the arc position of the guiding groove, the feeding plate just returns to the initial position. Due to the limitation of the arc structure of the guiding groove at the end of the sliding plate connected with the sliding column, this end will have a tendency to move downward, and the entire sliding plate will have a tendency to move downward under the action of gravity, so that the stop block disengages from the contact with the storage bin. When the two are disengaged, the storage bin loses the block on the stop block. At this time, the entire sliding plate can return to the rectangular groove under the action of the spring for the next feeding of the steel bars.

[0017] (4) After the steel bars complete the heading operation, by using the inclined surfaces on both sides of the unloading mechanism, driving it to move upward outside the fixed bearing block can successively drive the three steel bars to disengage from the fixed bearing block, thereby completing the unloading operation. During the upward movement of the unloading mechanism, the rack and the gear are engaged to drive the rotating rod to rotate clockwise, and then the box door rotates clockwise to open. That is, when the steel bars disengage from the fixed bearing block, they can be guided into the area enclosed by the baffle on the bottom plate under the action of the guiding table, facilitating the operator to centrally collect the processed steel bars.

Detailed implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0032] Please refer to Figures 1-11 , this embodiment provides a heading equipment for metal steel bar processing, including a stamping box 7 arranged on the bottom plate 1, and a material transfer mechanism 25 and a stamping mechanism for heading the steel bar a are arranged inside the stamping box 7.

[0033] Among them, the material transfer mechanism 25 is driven by the second cylinder 24 at its bottom to lift in the vertical direction. And the stamping mechanism is as Figure 7As shown in the figure, it includes a radial stamping mechanism 30 distributed on both sides of the material transfer mechanism 25 and a transverse stamping mechanism 23 installed on the side wall of the stamping box 7. The radial stamping mechanism 30 includes a fixed bearing block and a movable bearing block arranged in the vertical direction. The fixed bearing block is fixed to the bottom end inside the stamping box 7. The top of each movable bearing block is connected with a connecting column 28 in the vertical direction. The two connecting columns 28 extend upward to the outside of the stamping box 7 and are jointly connected to the movable plate 27. A third cylinder 26 is installed on the top wall inside the stamping box 7. The piston end of the third cylinder 26 extends upward to the outside of the stamping box 7 and is fixedly connected to the bottom of the movable plate 27. In the initial state, the material transfer mechanism 25 is located above the fixed bearing block. When the steel rod a is loaded into the three grooves on the material transfer mechanism 25, the second cylinder 24 drives the material transfer mechanism 25 to move downward. At this time, the steel rod a inside the material transfer mechanism 25 falls into the fixed bearing blocks on both sides. Then, the third cylinder 26 is started to drive the movable plate 27 to move downward, thereby driving the two movable bearing blocks to move towards the corresponding fixed bearing blocks. Guide columns 29 are fixedly connected in the vertical direction corresponding to both ends of the movable plate 27 on the outside of the stamping box 7. The movable plate 27 is slidably sleeved on the guide columns 29, and the guide columns 29 can play a guiding role to ensure the precise cooperation between the movable bearing block and the fixed bearing block. Pressing ring grooves adapted to the outer diameter of the steel rod a are provided in pairs on both the fixed bearing block and the movable bearing block. The steel rod a falls into the pressing ring groove inside the fixed bearing block, and the extrusion of the steel rod a is completed by the downward movement of the movable bearing block.

[0034] The transverse stamping mechanism 23 includes a stamping block arranged towards the fixed bearing block. The stamping block is drivingly connected to a first cylinder 10 fixed on the outer wall of the stamping box 7. And a stamping port concentric with the pressing ring groove is formed on the side of the stamping block facing the fixed bearing block. After the steel rod a is fixed by the radial stamping mechanism 30, then the first cylinder 10 is started to drive the transverse stamping mechanism 23 to move towards both ends of the steel rod a, and the upsetting operation of the steel rod a is completed under the cooperation of the transverse stamping mechanism 23 and the radial stamping mechanism 30.

[0035] As Figure 1As shown in the figure, a feeding plate 3 for transporting steel rod a to the stamping mechanism is also arranged on the top of the bottom plate 1. A storage box 6 for storing steel rod a is supported and fixed between the feeding plate 3 and the stamping box 7 by a support frame 5. The steel rod a is neatly placed inside the storage box 6 from top to bottom in sequence. Both the top and bottom of the storage box 6 are open. The two sides at the opening of the top of the storage box 6 are arranged in an inclined structure to facilitate feeding. A heating area for heat-treating the steel rod a is formed inside the storage box 6. The heating area is formed by resistance wires installed on the inner wall of the storage box 6. After all the steel rod a are placed inside the storage box 6, they are all heat-treated, which can shorten the processing time of the steel rod a. Three material holding grooves 4 adapted to the shape of the steel rod a are arranged in parallel inside the feeding plate 3. The feeding plate 3 moves horizontally in a straight line along the length direction of the bottom plate 1 and is tangent to the opening at the bottom of the storage box 6. It should be noted that the depth of the material holding groove 4 here needs to ensure that it can completely accommodate the steel rod a. After the steel rod a falls into one of the material holding grooves 4, the entire feeding plate 3 can also slide smoothly along the opening at the bottom of the storage box 6. A notch corresponding to the material transfer mechanism 25 is formed in the middle of the feeding plate 3. The setting of this notch is to avoid interference between the material transfer mechanism 25 and the feeding plate 3 when the material transfer mechanism 25 moves upward after the feeding plate 3 enters the stamping box 7. During the movement of the feeding plate 3 towards the stamping mechanism inside the stamping box 7, it first passes through the storage box 6. The heated steel rod a inside the storage box 6 first falls into the three material holding grooves 4, and then the steel rod a moves upward through the material transfer mechanism 25 and falls into the material transfer mechanism 25. Finally, the second cylinder 24 drives the material transfer mechanism 25 to move downward and fall into the fixed bearing block.

[0036] Since the feeding plate 3 is selected in this application to send the steel rod a in the storage box 6 into the stamping box 7, if the above scheme is adopted, during the process of the feeding plate 3 returning to the initial position, the steel rod a inside the storage box 6 will fall into the material holding groove 4. At this time, the stamping mechanism inside the stamping box 7 is still performing the upsetting operation on the steel rod a. Then, the steel rod a that falls into the material holding groove 4 prematurely will have a temperature loss, which not only causes waste of heat but also affects the forming of the upsetting. To avoid the occurrence of the above situation, a rectangular groove communicating with the notch is formed in the middle of the feeding plate 3 in this application, as Figure 4 and Figure 5 shown. The communicating part between the rectangular groove and the notch is in an arc structure. A sliding plate 15 is slidably installed inside the rectangular groove along the length direction of the feeding plate 3. The top of the sliding plate 15 is flush with the feeding plate 3. One end of the sliding plate 15 facing the material holding groove 4 is elastically connected with a stop block 16 in the vertical direction. One side of the stop block 16 facing the storage box 6 is in an arc structure, and when the sliding plate 15 moves to contact the storage box 6, the stop block 16 can retract into the sliding plate 15 to avoid the sliding plate 15 being stuck. When the sliding plate 15 disengages from the bottom of the storage box 6, the stop block 16 can return to the initial position under the action of elasticity.

[0037] Further, guiding grooves 19 parallel to the groove bottom are formed on the two side walls inside the rectangular groove. On both sides of the end of the sliding plate 15 away from the stop block 16, sliding columns 44 adapted to the guiding grooves 19 are fixedly connected. The sliding columns 44 are embedded in the guiding grooves 19 and are in sliding fit connection therewith. Along the length direction of the feeding plate 3, a spring groove 17 communicating with the rectangular groove is further formed inside the feeding plate 3. A spring 18 is arranged inside the spring groove 17. One end of the spring 18 is connected to the inner end of the spring groove 17, and the other end is connected to the sliding plate 15. The restoring force direction of the spring 18 faces the side away from the sliding plate 15. When the feeding plate 3 moves into the stamping box 7 during the implementation of this solution, the feeding plate 3 first passes through the bottom of the storage box 6. The three steel bars a inside the storage box 6 respectively fall into the three material receiving grooves 4. The feeding plate 3 continues to move forward. The stop block 16 contacts the bottom of the storage box 6. At this time, the stop block 16 retracts into the sliding plate 15 under the action of the storage box 6, ensuring that the feeding plate 3 smoothly passes through the storage box 6. When the steel bar a is transmitted into the fixed bearing block, at this time the feeding plate 3 starts to return. When the stop block 16 contacts the storage box 6 and is blocked by it, the feeding plate 3 continues to return. At this time, the sliding plate 15 remains stationary and moves towards the side of the material receiving groove 4 relative to the rectangular groove. The steel bar a inside the storage box 6 is blocked by the sliding plate 15 and will not fall into the material receiving groove 4, ensuring that it continues to be heat-treated inside the storage box 6 and avoiding heat loss caused by the premature entry of the steel bar a into the material receiving groove 4. And the spring 18 is in a stretched state. The sliding columns 44 on both sides of the sliding plate 15 slide inside the guiding grooves 19. When the sliding columns 44 slide to the arc position of the guiding grooves 19, the feeding plate 3 just returns to the initial position. Due to the limitation of the arc structure of the guiding grooves 19, the end of the sliding plate 15 connected with the sliding columns 44 will have a tendency to move downward. The whole sliding plate 15 will have a tendency to move downward under the action of gravity, so that the stop block 16 is separated from the contact with the storage box 6. When the two are separated from contact, the storage box 6 loses the block on the stop block 16. At this time, the whole sliding plate 15 can return to the rectangular groove under the action of the spring 18 for the next feeding of the steel bar a.

[0038] As Figure 6As shown in the figure, inside the storage bin 6, a first heating zone 20, a second heating zone 21, and a third heating zone 22 are formed in sequence from top to bottom, and the heating temperatures of the three heating zones are distributed in a stepped manner from low to high in sequence. Since the heat generated by the resistance wires arranged on the inner wall of the storage bin 6 will dissipate upward, the temperature of the third heating zone 22 at the bottom of the storage bin 6 only needs to be kept the highest. This can not only meet the heating treatment of the three steel bars a at the bottom of the storage bin 6, but also when the heat generated by the resistance wires in this area dissipates upward, it will also heat the steel bars a in the other two areas, making full use of the heat in the third heating zone 22 area, and also reducing the heat generation of the resistance wires as a whole, further saving energy.

[0039] As Figure 7 shown, the present application also sleeved a discharging mechanism 31 outside each fixed bearing block. The discharging mechanism 31 is inclined towards the side walls of the material transferring mechanism 25 and the transverse stamping mechanism 23. Taking the side of the stamping box 7 close to the storage bin 6 as the feeding end and the side far from the storage bin 6 as the discharging end, the height of the inclined structure of the discharging mechanism 31 gradually decreases from the feeding end to the discharging end. The side of the discharging mechanism 31 close to the feeding end is in a closed structure, and the side close to the discharging end is in an open structure. When the heading operation of the steel bar a is completed, it is necessary to remove it from the fixed bearing block. At this time, using the structure of the discharging mechanism 31 itself and driving it to move upward outside the fixed bearing block, the three steel bars a can be driven to disengage from the fixed bearing block one by one. As Figure 8 shown, a fixed block 32 is connected to the side wall of each discharging mechanism 31 facing the feeding end of the stamping box 7. A connecting rod 33 is fixedly sleeved between the two fixed blocks 32. The two ends of the connecting rod 33 extend towards the inner wall of the stamping box 7 and are fixedly connected with racks 34 in the vertical direction. A slide rail 35 is arranged on the inner wall of the stamping box 7 corresponding to the position of the rack 34. The rack 34 is slidably and guidingly assembled in the slide rail 35. A threaded rod 36 is rotatably installed along the length direction on the inner side of the slide rail 35. The rack 34 is threadedly sleeved on the threaded rod 36. By driving the threaded rod 36 to rotate through an external power device (a motor can be selected), the rack 34 can be driven to slide in the vertical direction. Since the discharging mechanism 31 is connected to the rack 34, it can move upward on the corresponding fixed bearing block to disengage the steel bar a from the fixed bearing block.

[0040] As Figure 1 shown, a box door 8 is hinged at the discharging end of the stamping box 7. Since the steel bar a is headed under stamping inside the stamping box 7, in order to improve the safety of the operation, the discharging end of the stamping box 7 needs to be set as a sealed structure, and the box door 8 can play an isolation role, thereby enhancing the safety of the entire device. As Figure 11 shown, T-shaped sliding grooves 43 are opened vertically on both sides of the box door 8. As Figure 9 and Figure 10As shown in the figure, on both inner side walls of the stamping box 7, there are rotating rods 41 rotatably installed through fixed shafts. The end of the rotating rod 41 is connected with a sliding member 42. The end of the rotating rod 41 is inserted into the T-shaped chute 43 through the sliding member 42 and is in sliding fit connection with it. By rotating the rotating rod 41 clockwise, the sliding member 42 can be driven to slide in the T-shaped chute 43 of the box door 8, thereby opening the box door 8. The two fixed shafts extend in the direction towards each other through the rotating rod 41 and are fixedly sleeved with second sprockets 40. On the two inner side walls of the stamping box 7, there are also gears 37 rotatably installed respectively and meshing with the rack 34, and the gears 37 are arranged between the feeding end of the stamping box 7 and the rack 34. On the opposite sides of the two gears 37, there is a first sprocket 38 integrally formed. A chain 39 is sleeved between the first sprocket 38 and the corresponding second sprocket 40. The chain 39 is arranged horizontally and is located above the horizontal stamping mechanism 23 to prevent interference between the horizontal stamping mechanism 23 and the chain 39 when the horizontal stamping mechanism 23 moves towards the fixed bearing block. When implementing this solution, first, the rack 34 and the discharging mechanism 31 are driven to move upward by rotating the threaded rod 36. Among them, the upward movement of the discharging mechanism 31 can drive the steel bar a on the fixed bearing block to break away. At the same time, during the upward movement of the rack 34, it meshes with the gear 37, thereby driving the gear 37 and the first sprocket 38 to rotate clockwise synchronously. The second sprocket 40 also rotates clockwise synchronously through the chain 39 and the first sprocket 38, thereby opening the box door 8. That is to say, when the steel bar a breaks away from the fixed bearing block, the box door 8 is also opened. In addition, on one side of each fixed bearing block facing the discharging end, there is a material guiding platform 45 connected. One end of the material guiding platform 45 is flush with the top of the fixed bearing block, and the other end extends obliquely to be flush with the bottom plate 1. On the bottom plate 1, near the discharging end of the stamping box 7, there is a baffle plate 9 integrally formed. After the box door 8 is opened, the steel bar a that breaks away from the fixed bearing block finally flows out of the stamping box 7 through the guiding of the material guiding platform 45. The entire material taking process not only realizes automation but also can open the box door 8 while taking the material, and the steel bar a is directly discharged outside the stamping box 7, greatly shortening the material taking time of the steel bar a.

[0041] As Figure 1 and Figure 3 shown in the figure, a sliding seat 2 is fixed at the top of the bottom plate 1 and below the feeding plate 3. The feeding plate 3 is slidably guided and assembled on the sliding seat 2 through the slider 14 at its bottom. The slider 14 slides along the sliding seat 2 to drive the feeding plate 3 to realize the feeding of the steel bar a, and the sliding of the slider 14 on the sliding seat 2 can be realized through a rodless cylinder or a nut-screw pair structure in the prior art. In addition, on both sides of the sliding seat 2 along its length direction, there are formed limiting grooves 12. On the inner side of the slider 14, there is a triangular rib integrally formed and adapted to the limiting groove 12. The cooperation between the triangular rib and the limiting groove 12 can further improve the stability of the cooperation between the slider 14 and the limiting groove 12.

[0042] Refer to the appendix again Figure 3, at one end of the sliding seat 2 facing the storage bin 6, a second guiding roller 13 for supporting the loading plate 3 is rotatably installed along the width direction of the sliding seat 2. The bottom of the loading plate 3 and the second guiding roller 13 adopt rolling friction, which can not only support the loading plate 3 but also reduce the friction between the two. As Figure 2 shown, on the outer walls of the opposite sides of the two support frames 5, a first guiding roller 11 for supporting the loading plate 3 is rotatably installed. Since the length of the loading plate 3 itself is relatively long, in order to ensure that the loading plate 3 can always be in a tangential motion with the bottom of the storage bin 6 each time, in this application, the first guiding roller 11 is installed on the two support frames 5, and the first guiding roller 11 can reduce the bending moment borne by the loading plate 3 itself.
