Description

Technical Field

[0001] This utility model relates to the field of shovel mold technology, specifically a mold for shovel processing. Background Technology

[0002] The blade of a forklift, also known as the bucket or shovel, is one of the key working components of a forklift (such as a loader or bulldozer), mainly used for digging, transporting, leveling, and stockpiling materials. The blade is a plate-shaped metal tool mounted on the front of the forklift, typically made of high-strength steel, possessing wear-resistant and impact-resistant properties. The main body of the blade is the shovel plate, which is mostly a flat plate structure. The rear end of the shovel plate is generally rectangular, while the front end is typically sloped. During the manufacturing process of the blade, a stamping die is used to punch holes in the shovel plate.

[0003] When stamping the spade plate of a shovel using a stamping die, the spade plate will be subjected to a large impact force during the punching process. If the spade plate is directly transferred to the stamping station through a conveying device, the subsequent impact force will directly act on the conveying device, which may cause damage or malfunction. Therefore, currently, multiple workers work together to complete the loading and unloading of the spade plate. However, this operation not only increases the workload of the workers, but also reduces the actual work efficiency. Moreover, manually loading the spade plate to the stamping station also poses a significant safety hazard. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a mold for processing shovels.

[0005] The present invention provides a mold for processing shovel blades, including a base and a bracket mounted on the base. A punching machine and a pusher are respectively installed at the upper and lower ends of the bracket. The conveying end of the pusher faces upward and is equipped with a support platform. The shovel blade to be punched is placed on the upper surface of the support platform and fixed by fasteners. The pusher transmits the support platform and the shovel blade on it to the punching station below the punching machine.

[0006] The support has legs located on the outside of both sides of the support platform, and guide rails are installed on the inner side of the legs of the support. The two ends of the support platform are slidably assembled with the adjacent guide rails respectively.

[0007] The base is equipped with hydraulic support rods, which support the bottom sides of the bearing platform located at the stamping station.

[0008] As a further optimization of this utility model, the end of the guide rail near the support platform is hemispherical, and both sides of the support platform are provided with sliding grooves adapted to the support platform. The cross-sectional shape of the sliding grooves is semi-circular. When the pusher drives the support platform into the stamping station, the sliding grooves on both sides of the support platform are slidably inserted into the adjacent guide rails.

[0009] As a further optimization of this utility model, the number of hydraulic support rods is two sets, and the two sets of hydraulic support rods are respectively set in the gap between the pusher and the adjacent support leg, with multiple hydraulic support rods in each set evenly distributed along the length direction of the bearing platform.

[0010] As a further optimization of this utility model, the axis of the hydraulic support rod is located between the angle between the support leg of the bracket and the base, and the movable end of the hydraulic support rod extends obliquely upward and is equipped with a support plate.

[0011] As a further optimization of this utility model, a waste discharge channel is provided on the support platform corresponding to the punching position. Both the upper and lower ends of the waste discharge channel are open, and a conveyor installed on the upper surface of the base is provided below the lower opening of the waste discharge channel.

[0012] As a further optimization of this utility model, the pusher is an electric screw pusher mechanism, and there are two pushers symmetrically distributed on both sides of the upper end face of the base, and the conveyor is installed between the two pushers.

[0013] As a further optimization of this utility model, the fastener includes a first limiting block and a second limiting block. The first limiting block and the second limiting block are detachably installed on both sides of the upper surface of the support platform. The shovel plate is disposed between the first limiting block and the second limiting block. The side of the first limiting block near the rear end of the shovel plate has an inner right-angle groove that matches it. The side of the second limiting block near the front end of the shovel plate has an oblique groove that matches it. The first limiting block and the second limiting block are respectively engaged with the rear end and the front end of the shovel plate and fastened with bolts.

[0014] As a further optimization of this utility model, the upper surface of the support platform is provided with a positioning groove that matches the lower end of the shovel plate, and the first limiting block and the second limiting block are respectively installed on both sides of the positioning groove.

[0015] The mold for processing spades proposed in this utility model has the following beneficial effects:

[0016] (i) By setting up a support platform, guide rail and hydraulic support rod, the shovel is placed on the support platform. The pusher is used to transfer the support platform and the shovel on it to the stamping station. During the stamping process, the hydraulic support rod supports the bottom sides of the support platform. Combined with the sliding assembly of the support platform and the guide rail, the impact force during punching is effectively dispersed and borne, avoiding the impact force from acting directly on the pusher, greatly reducing the risk of equipment damage and extending the service life of the conveying equipment.

[0017] (ii) The carrier platform and the shovel plate on it are precisely pushed to the stamping station by the pusher. After the punching is completed, the carrier platform can be sent out. At the same time, the waste is discharged with the help of the conveyor. The whole process is highly automated, reducing manual operation links, reducing labor costs, and greatly improving the working efficiency of shovel processing.

[0018] (III) This utility model realizes automated feeding and unloading. The staff only needs to place the shovel plate on the support platform and fix it. The subsequent operations are all completed automatically by the equipment. The staff stay away from the dangerous area of ​​stamping, effectively avoiding the safety risks caused by manual operation and improving the safety of the production process.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] Please see Figure 1 A mold for processing shovel blades includes a base 1 and a bracket 2 mounted on the base 1. A punching machine 4 and a pusher 3 are respectively mounted on the upper and lower ends of the bracket 2.

[0029] The conveying end of the pusher 3 faces upward and is equipped with a support platform 5. The shovel plate 6 to be punched is placed on the upper surface of the support platform 5 and fixed by fasteners. The pusher 3 transmits the support platform 5 and the shovel plate 6 on it to the stamping station below the stamping machine 4.

[0030] The support 2 has legs located on the outside of both sides of the support platform 5, and guide rails 7 are installed on the inner side of the legs of the support 2. The two ends of the support platform 5 are slidably assembled with the adjacent guide rails 7 respectively. A hydraulic support rod 8 is installed on the base 1, which supports the bottom sides of the support platform 5 located in the stamping station.

[0031] The pusher 3 drives the bearing platform 5 to move along the guide rail 7 towards the stamping station below the press 4. Since the bearing platform 5 and the guide rail 7 are slidably assembled, the guide rail 7 can provide a stable guiding effect for the movement of the bearing platform 5, ensuring that the bearing platform 5 moves accurately to the stamping station. When the bearing platform 5 reaches the stamping station, the hydraulic support rod 8 is activated to support the bottom sides of the bearing platform 5. When the press 4 punches the shovel plate 6, part of the impact force is borne by the hydraulic support rod 8, and the other part is transmitted through the contact between the bearing platform 5 and the guide rail 7. This avoids the impact force acting directly on the pusher 3, effectively disperses and bears the impact force during punching, protects the pusher 3, reduces the risk of equipment damage, extends the service life of the pusher 3, and at the same time ensures that the shovel plate 6 can be accurately transported to the stamping station for processing.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the guide rail 7 is hemispherical at one end near the bearing platform 5. Both sides of the bearing platform 5 are provided with sliding grooves that are adapted to the bearing platform 5. The cross-sectional shape of the sliding grooves is semi-circular. When the pusher 3 drives the bearing platform 5 into the stamping station, the sliding grooves on both sides of the bearing platform 5 are slidably inserted into the adjacent guide rail 7.

[0033] The pusher 3 pushes the carrier platform 5 to move. The semi-circular grooves on both sides of the carrier platform 5 contact and slide into the hemispherical end of the guide rail 7. During the movement, the hemispherical guide rail 7 cooperates with the semi-circular grooves, which can not only better guide the movement direction of the carrier platform 5, but also reduce the friction between the two to a certain extent, making the movement of the carrier platform 5 smoother. The cooperation structure between the carrier platform 5 and the guide rail 7 is optimized, which improves the smoothness and accuracy of the movement of the carrier platform 5, and further ensures that the shovel plate 6 can accurately reach the stamping station, which helps to improve the processing accuracy.

[0034] Furthermore, such as Figure 1 and Figure 2As shown, there are two sets of hydraulic support rods 8. The two sets of hydraulic support rods 8 are respectively set in the gap between the pusher 3 and the adjacent support leg. Multiple hydraulic support rods 8 in each set are evenly distributed along the length of the bearing platform 5.

[0035] After the bearing platform 5 reaches the stamping station, the two sets of hydraulic support rods 8 start simultaneously. Multiple hydraulic support rods 8 evenly distributed in each set support the bottom sides of the bearing platform 5 together, dispersing the pressure and impact force of punching on the bearing platform 5 from multiple support points. Due to the even distribution, the bearing platform 5 is more evenly stressed when supported, ensuring the stability of the bearing platform 5 during the stamping process. This allows the bearing platform 5 to withstand the punching impact force more smoothly, further reducing the risk of equipment damage due to uneven stress, and also helps to improve the punching quality of the shovel plate 6.

[0036] Furthermore, the axis of the hydraulic support rod 8 is located between the angle between the support leg of the bracket 2 and the base 1, and the movable end of the hydraulic support rod 8 extends obliquely upward and is equipped with a support plate.

[0037] When the hydraulic support rod 8 starts to extend, its upwardly extending movable end drives the support plate to rise. The support plate contacts the bottom of the support platform 5 and provides support force. This inclined support method can better transfer the force on the support platform 5 to the base 1 and the bracket 2. By utilizing the stability principle of triangles, the stability of the support structure is enhanced, the support effect of the hydraulic support rod 8 is improved, the stability of the entire mold during the stamping process is enhanced, the possibility of equipment shaking and damage is further reduced, and the stability and reliability of the punching process of the shovel plate 6 are guaranteed.

[0038] Furthermore, such as Figure 2 As shown, a waste discharge channel 13 is provided on the support platform 5, which is corresponding to the punching position. Both the upper and lower ends of the waste discharge channel 13 are open, and a conveyor 11 installed on the upper surface of the base 1 is provided below the lower opening of the waste discharge channel 13.

[0039] When the stamping press 4 punches holes in the shovel plate 6, the punched waste material falls from the punched holes in the shovel plate 6 and drops onto the conveyor 11 below through the corresponding waste discharge channel 13 on the bearing platform 5. After the conveyor 11 starts, it transports the waste material out of the mold working area, realizing the automatic discharge of waste material. This avoids the waste material accumulating in the mold and affecting the processing, reduces the workload of manually cleaning waste material, improves production efficiency, and also ensures the cleanliness of the mold interior, which is conducive to the normal operation of the equipment.

[0040] Furthermore, such as Figure 2 As shown, the pusher 3 is an electric screw pusher mechanism. There are two pushers 3, which are symmetrically distributed on both sides of the upper end face of the base 1. The conveyor 11 is installed between the two pushers 3.

[0041] When the bearing platform 5 and its shovel plate 6 need to be transported to the stamping station, two symmetrically distributed electric screw pushing mechanisms are started simultaneously. The rotation of the screw drives the bearing platform 5 to move towards the stamping station. Since the two pushers 3 are symmetrically distributed and work synchronously, the bearing platform 5 can be evenly stressed and move stably towards the stamping station. When the waste is discharged, the conveyor 11 is located between the two pushers 3, receiving the waste falling from the waste discharge channel 13 and transporting it out, which improves the stability and accuracy of the conveying of the bearing platform 5 and ensures that the shovel plate 6 can accurately reach the stamping station. At the same time, the reasonable layout makes the equipment structure compact, which facilitates the collection and transportation of waste and improves the overall work efficiency.

[0042] Furthermore, such as Figure 1 and Figure 2 As shown, the fastener includes a first limiting block 9 and a second limiting block 10. The first limiting block 9 and the second limiting block 10 are detachably installed on both sides of the upper end face of the support platform 5. The shovel plate 6 is disposed between the first limiting block 9 and the second limiting block 10. The side of the first limiting block 9 near the rear end of the shovel plate 6 has an inner right-angle groove that matches it. The side of the second limiting block 10 near the front end of the shovel plate 6 has an oblique groove that matches it. The first limiting block 9 and the second limiting block 10 are respectively engaged with the rear end and the front end of the shovel plate 6 and fastened with bolts.

[0043] When placing the shovel plate 6, the rear end of the shovel plate 6 is inserted into the inner right-angle groove of the first limiting block 9, and the front end is inserted into the oblique groove of the second limiting block 10. Then, the first limiting block 9 and the second limiting block 10 are fastened with bolts. This snapping and fastening method can make the shovel plate 6 more firmly fixed on the support table 5, and it will not be displaced during the pushing and punching process. This ensures that the shovel plate 6 is firmly fixed on the support table 5, avoids the deviation of the punching position due to loosening of the shovel plate 6 during the processing, and improves the processing accuracy of the shovel plate 6.

[0044] Furthermore, such as Figure 2 As shown, the upper end face of the support platform 5 is provided with a positioning groove 12 that is adapted to the lower end of the shovel plate 6, and the first limiting block 9 and the second limiting block 10 are respectively installed on both sides of the positioning groove 12.

[0045] When placing the shovel plate 6, first place the lower end of the shovel plate 6 into the positioning groove 12 to initially position the shovel plate 6. Then, install the first limiting block 9 and the second limiting block 10 for further fixation. The positioning groove 12 is adapted to the lower end of the shovel plate 6 and can restrict the horizontal movement of the shovel plate 6 on the support table 5. With the cooperation of the first limiting block 9 and the second limiting block 10, the positioning of the shovel plate 6 on the support table 5 is more accurate, which further improves the positioning accuracy of the shovel plate 6 on the support table 5. This helps to improve the accuracy of the punching process of the shovel plate 6, reduce the scrap rate, and improve the production quality.

[0046] When processing the shovel blade, the worker first places the lower end of the shovel plate 6 into the positioning groove 12 on the support platform 5, so that the rear end of the shovel plate 6 is engaged in the inner right-angle groove of the first limiting block 9 and the front end is engaged in the oblique groove of the second limiting block 10. Then, the first limiting block 9 and the second limiting block 10 are fastened with bolts to fix the shovel plate 6 on the support platform 5. At this time, two symmetrically distributed pushers 3 are started. The pushers 3 drive the support platform 5 to move along the guide rail 7 to the stamping station below the stamping machine 4.

[0047] When the bearing platform 5 reaches the stamping station, the two sets of hydraulic support rods 8 are activated. Their upwardly extending movable ends drive the support plate to rise and support the bottom sides of the bearing platform 5. Subsequently, the stamping machine 4 is activated to punch the shovel plate 6. The impact force generated by punching is jointly borne by the hydraulic support rods 8 and the guide rail 7, which protects the pusher 3. The punched waste material falls through the waste discharge channel 13 on the bearing platform 5 onto the conveyor 11 below. The conveyor 11 transports the waste material out of the mold working area.

[0048] After punching is completed, the hydraulic support rod 8 retracts, and the pusher 3 moves in the opposite direction, sending the bearing platform 5 and the processed shovel plate 6 out of the stamping station. The whole process realizes automated feeding, processing and unloading. The staff only needs to perform the initial clamping operation, away from the dangerous area of ​​stamping, which improves the safety and work efficiency in the production process.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
