Description

Technical Field

[0001] This invention relates to the field of blade corner molding technology, and more specifically to a novel bulldozer blade corner molding die. Background Technology

[0002] The bulldozer blade is a key component used in conjunction with the bulldozer blades. It is typically machined from materials such as boron steel or carbon steel, and undergoes heat treatment processes such as quenching and tempering to improve its hardness and compressive strength, meeting the demands of high-intensity operations. Working in tandem with the bulldozer blades, it undertakes tasks such as bulldozing and leveling the ground, and is one of the core working parts of the bulldozer.

[0003] Chinese utility model patent application number 201920659210.X – A bulldozer blade corner integrated pressure tire, including an upper pressure tire and a lower pressure tire, with their end faces aligned; an upper pressure tire plate is provided above the upper pressure tire, and a lower pressure tire plate is provided below the lower pressure tire; a positioning block is bolted to the rear side of the lower pressure tire, and a notch is provided at the front of the lower pressure tire; two positioning block slots are provided on the positioning block, and the two positioning block slots are symmetrically arranged on the positioning block; a positioning baffle is engaged between one positioning block slot and the notch, and a blade corner is provided between the positioning baffle and the lower pressure tire.

[0004] This patented technology involves replacing a positioning baffle to produce cutting edges of different specifications and sizes through pressing. The high-temperature cutting edge blank is placed on the upper surface of the lower tire body on one side of the positioning baffle, and a press drives the upper tire body downwards to form the cutting edge shape. After completion, the cutting edge needs to be removed by two people working together at high temperatures: one person uses a pry bar to pry the cutting edge off the surface of the lower tire body, and the other person uses a clamp to hold the cutting edge away from the lower tire body. This process is inefficient and labor-intensive. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this invention provides a novel bulldozer blade corner forming mold. The technical problem it solves is that the formed blade corner requires two workers to work together to remove it under high temperature, resulting in low efficiency and a huge workload. To solve the above-mentioned technical problems, the technical solution adopted by this invention is: A new type of bulldozer blade corner forming mold includes an upper body, a lower body at the bottom of the upper body, and a positioning baffle on the lower body. Its distinguishing feature is that it further includes: Mounting holes, several mounting holes are provided in the lower tire body and extend to the upper surface of the lower tire body; The lifting seat is installed in the mounting hole by means of lifting. A power mechanism used to drive the movement of the lifting platform.

[0006] Furthermore, the power mechanism includes a linear telescopic power component, the output end of which is connected to a push plate, and the push plate has an inclined surface A. The lower part of the lifting seat has an inclined surface B that slides and fits against the inclined surface A.

[0007] Furthermore, the lower tire body has a sliding groove for the push plate to slide, and the sliding groove is connected to the mounting hole.

[0008] Furthermore, the linear telescopic power component is a pneumatic cylinder or a hydraulic cylinder, and the output shaft of the pneumatic cylinder or hydraulic cylinder is fixedly equipped with a connecting plate, which is connected to the push plate.

[0009] Furthermore, the positioning baffle has a through hole that communicates with the mounting hole, and the lifting seat can protrude from the upper surface of the positioning baffle under the drive of the power mechanism.

[0010] Furthermore, the lifting seat is equipped with rollers that rotate, with the upper edge of the rollers protruding from the upper surface of the lifting seat.

[0011] Furthermore, the upper side wall of the lifting seat is provided with an inclined surface C, and a support block for blocking the installation hole is provided on the inclined surface C in a sliding manner. A sliding limit structure is provided between the support block and the inclined surface C. When the lifting platform rises, the support block is restricted by the side wall of the mounting hole and rises with the lifting platform. After the support block leaves the mounting hole, it moves diagonally downward along the sliding limit structure to expose the roller.

[0012] Furthermore, the sliding limiting structure includes a slot opened along the inclined surface C, a slider is slidably connected to the slot, and the slider is fixedly connected to the support block.

[0013] Furthermore, the slots are symmetrically arranged on both sides of the roller, and the two support blocks, when combined, seal the outlet at the mounting hole.

[0014] Furthermore, the slot is a dovetail groove.

[0015] The beneficial effects of this invention are as follows: an installation hole is opened in the lower tire body, and a lifting seat is set in the installation hole. The lifting seat is raised by a power mechanism, thereby raising the die corner after pressing to above the positioning baffle. Only one worker is needed to complete the work of two people, which greatly improves work efficiency. Moreover, since the die corner has been raised to above the positioning baffle, the worker can use a tool on one side to push the die corner away from the press above the positioning baffle. Compared with the previous clamping and leaving, the current pushing and leaving is more labor-saving.

[0016] Rollers are installed on the upper part of the lifting platform. When the cutter is raised and pushed by the worker, the rollers can rotate accordingly, changing the sliding friction between the cutter and the lifting platform into rolling friction. This reduces the pushing resistance, making the cutting operation smoother and less strenuous, and further reducing the labor intensity of the workers. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this invention. The specific implementation scheme of this invention is as follows: Example 1: The new bulldozer blade corner forming mold includes an upper body 7, a lower body 8 at the bottom of the upper body 7, a positioning baffle 9 on the lower body 8, and mounting holes 10. Several mounting holes 10 are formed inside the lower body 8 and extend to the upper end face of the lower body 8. A lifting seat 11 is provided in the mounting hole 10. The lifting seat 11 is connected to a power mechanism 6 for driving the lifting seat 11 to rise and fall. When it is retracted into the mounting hole 11, it does not affect the forming of the blade corner blank. After forming, the lifting seat 11 extends out of the mounting hole 11 and the blade corner is raised above the positioning baffle. Only one worker is needed to complete the work that previously required two people, greatly improving work efficiency. Moreover, since the blade corner has been raised above the positioning baffle, the worker can use a tool on one side to push the blade corner away from the press above the positioning baffle. Compared to clamping and removing it, pushing it away is more labor-saving.

[0019] Specifically, the power mechanism 6 includes a linear telescopic power component 61, the output end of which is connected to a push plate 62. The push plate 62 has an inclined surface A63 and an inclined surface B64 located at the lower part of the lifting seat 11. The inclined surface B64 slides in contact with the inclined surface A63. When the push plate 62 slides into the lower tire body 8, its inclined surface A63 interacts with the inclined surface B64 of the lifting seat 11. Due to the sliding contact of the two inclined surfaces, the horizontal thrust of the push plate 62 is converted into a force that drives the lifting seat 11 to move upward, thereby causing the lifting seat 11 to rise along the axial direction of the mounting hole 10. Conversely, when the linear telescopic power component 61 drives the push plate 62 to slide outward from the lower tire body 8, the force of the inclined surface A63 on the inclined surface B64 gradually decreases, and the lifting seat 11 descends into the mounting hole 10 under its own weight, without affecting the subsequent placement of the cutting corner blank and the pressing operation.

[0020] It needs to be explained that, for example Figure 2 As shown, the lower tire body 8 has a sliding groove 12 for the push plate 62 to slide. The sliding groove 12 is connected to the mounting hole 10 and extends to the side of the lower tire body 8. The sliding groove 12 can limit the push plate 62 and ensure that the push plate 62 moves in a straight line.

[0021] Specifically, there are 6 mounting holes, arranged in pairs of two in three rows with intervals. Each pair of mounting seats is connected by a slide groove 12, forming three slide grooves 12. Each slide groove 12 contains a push plate 62, and a connecting plate 65 is fixedly connected to the push plate 62. The connecting plate 65 is connected to a linear telescopic power component 61, which is a cylinder or hydraulic cylinder. The output shaft of the cylinder or hydraulic cylinder is fixedly connected to the connecting plate 65. By using one linear telescopic power component 61 to drive all push plates 62 to move simultaneously, the lifting seat 11 is simultaneously raised and lowered to the preset height, which improves the synchronization of the lifting action and ensures that the blade angle is not obstructed by unevenness when pushed away by the worker after being raised.

[0022] A first idler roller conveyor is provided on one side of the press to transport the die corner after pressing to the next station. In order for the die corner to be lifted to the first idler roller conveyor, a through hole 13 communicating with the mounting hole 10 is provided on the positioning baffle 9. The lifting seat 11 can protrude from the upper surface of the positioning baffle 9 under the drive of the power mechanism 6. There is also a lifting seat 11 here.

[0023] It should be noted that the lifting seat 11 is equipped with a roller 16 in a rotating manner. The upper edge of the roller 16 protrudes from the upper surface of the lifting seat 11. When the blade is raised and pushed by the worker, the roller can rotate accordingly, changing the sliding friction between the blade and the lifting seat into rolling friction, reducing the pushing resistance, making the blade movement operation smoother and less labor-intensive, and further reducing the labor intensity of the worker.

[0024] Example 2: Based on Example 1, this example aims to solve the technical problem that "when the high-temperature blade corner blank is pressed, the blade corner blank will be pressed into the mounting hole, resulting in a circular protrusion at this point after the blade corner is formed, which affects the product quality".

[0025] The technical solution to the above technical problems is as follows: The upper side wall of the lifting seat 11 is provided with an inclined surface C18. The inclined surface C18 is provided with a support block 17 that blocks the mounting hole 10 in a sliding manner. After the lifting seat 11 falls and resets the support block 17 to block the mounting hole 10, the upper end face of the support block 17 is flush with the upper end face of the lower tire body 8. A sliding limit structure is provided between the support block 17 and the inclined surface C18. When the lifting seat 11 rises, the support block 17 is restricted by the side wall of the mounting hole 10 and rises with the lifting seat 11. After the support block 17 is separated from the mounting hole 10, the support block 17 is pressured by the blade angle and moves obliquely downward along the sliding limit structure until the roller 16 is exposed to support the blade angle.

[0026] The beneficial effects of this embodiment are as follows: When the lifting seat 11 is reset, the support block 17 completely and flush with the mounting hole 10, which prevents the high-temperature blade blank from sinking into the mounting hole 10 due to pressure during the pressing process and causing a protrusion, thus ensuring the flatness of the bottom surface of the blade; after the lifting seat 11 is raised, the support block 17 can open to one side to expose the roller 16, which facilitates the subsequent pushing of the blade. The structure is simple, which not only ensures product quality and quality, but also facilitates the pushing of the blade.

[0027] Specifically, the sliding limit structure includes a slot 14 opened along the inclined surface C18. A slider 15 is slidably connected to the slot 14. The slider 15 is fixedly connected to the support block 17. The function of the slot 14 is to ensure that the slider 15 can only move along the extension direction of the slot 14. When the lifting seat 11 drives the support block 17 to rise, after the support block 17 disengages from the mounting hole 10, under the pressure of the blade angle and the upward movement of the lifting seat 11, the support block 17 moves obliquely downward through the cooperation of the slider 15 and the slot 14. It should be noted that the slot 14 is a dovetail groove, and the slider 15 has a dovetail structure to fit into the dovetail groove without disengaging.

[0028] It should be noted that the slots 14 are symmetrically arranged on the inclined surfaces C18 on both sides of the roller 16. After the two support blocks 17 are combined, they will block the outlet of the mounting hole 10. The upper surface of the support block 17 is flush with the horizontal plane of the lower tire body 8. The slider 15 has a groove 19 to accommodate the roller 16 and avoid the roller 16.

[0029] Example 3: Based on the above embodiments, this embodiment aims to solve the technical problem that "after the blank is pressed, it is lifted by the lifting seat 11 to the top of the positioning baffle 9, but workers still need to put their bodies into the press to push the blank away from the press, which poses a certain safety hazard".

[0030] The technical solution to the above technical problems is as follows: A material feeding mechanism is provided on the upper tire body 7. The material feeding mechanism includes a driving member 1 provided on opposite sides of the upper tire body 7. The driving member 1 is connected to a moving plate 2. A material feeding member 3 is provided between the two moving plates 2. The material feeding member 3 is connected to the moving plate 2 through an inclined sliding structure 4. A stop 5 is provided on one side of the material feeding member 3. After the moving plate 2 drives the material feeding member 3 to move but is blocked by the stop 5, the material feeding member 3 moves obliquely upward to the moving plate 2 away from the stop 5 through the inclined sliding structure 4.

[0031] When material removal is required, the moving plate 2 and the material removal component 3 are driven by the driving component 1 to push the blade corner away from the lower die body 8. When material removal is not required, when the material removal component 3 moves to the stop 5 and is blocked, under the blocking force of the stop 5, the material removal component 3 moves obliquely upward relative to the moving plate 2 away from the stop 5 through the inclined sliding structure 4, thereby realizing the lifting and avoidance of the material removal component, and thus preventing the material removal component 3 from blocking the blade corner blank from entering the lower die body 8.

[0032] The beneficial effects of this embodiment are: no manual intervention is required, which effectively reduces the labor intensity of operators and improves production safety.

[0033] Specifically, the material ejector 3 includes an ejector plate 31, with fixing plates 32 at both ends. The ejector plate 31 is used to pull the blank into the lower die, and the fixing plates 32 are used to cooperate with the inclined sliding structure 4. Specifically, as shown...Figure 2 As shown, the inclined sliding structure 4 includes an inclined slide groove 41 formed on the movable plate 2. The lower end of the inclined slide groove 41 is close to the stop 5 and the upper end is far away from the stop 5. A slider 42 is slidably arranged in the inclined slide groove 41. The slider 42 is fixedly connected to the fixed plate 32.

[0034] In another embodiment, the inclined sliding structure 4 includes an inclined slide groove 41 formed on the fixed plate 32. The lower end of the inclined slide groove 41 is close to the stop 5 and the upper end is far away from the stop 5. A slider 42 is slidably arranged in the inclined slide groove 41. The slider 42 is fixedly connected to the moving plate 2.

[0035] It should be noted that the stop 5 includes a mounting plate 51, which is connected to the press via a connecting plate. A bearing 52 is provided on one side of the mounting plate 51, and the bearing 52 is located on the moving track of the fixed plate 32. When the fixed plate 32 is blocked by the bearing 52, it can slide upward more smoothly.

[0036] Several bearings 52 are arranged at vertical intervals to ensure that the fixing plate 32 can contact the bearings 52 at different height positions.

[0037] It should be noted that the material feeding plate 31 is arranged in a > structure, and a folding plate 33 is fixedly provided on the inner side of the middle corner of the material feeding plate 31, which can better fit the two side shapes of the blade corner blank and improve the mold entry accuracy of the blade corner blank. It should be noted that during the material feeding operation, the material feeding component 3 has sufficient self-weight to push the blade corner blank without moving it upward.

[0038] Specifically, the drive component 1 is a rodless cylinder, and the rodless cylinder model is MY1B mechanical rodless cylinder.

[0039] To simultaneously press two corner blanks and improve work efficiency, a ridge-shaped protrusion 20 is provided in the middle of the lower die body 8. An inclined stop 21 is fixedly provided on the upper surface of the lower die body 8 on one side of the ridge-shaped protrusion 20. The inclined stop 21, the ridge-shaped protrusion 20, and the positioning baffle 9 form a pressing mold cavity. Rotating wheels 22 are spaced apart at the ridge-shaped protrusion 20, allowing the corner blanks to easily slide into the pressing mold cavity. Figure 10 As shown, a groove 23 is provided in the middle of the upper tire body 7 to avoid the rotating wheel 22.

[0040] The working principle and process of this embodiment three are as follows: like Figure 11 As shown, the rodless cylinder 1 and the stop 5 are fixedly installed on the press heads of the press on both sides of the upper tire body.

[0041] After the blank of the blade corner is formed, the hydraulic cylinder 61 is activated. The hydraulic cylinder 61 drives the push plate 62 to move into the lower tire body 8 through the connecting plate 65. At this time, due to the sliding contact between the inclined surface A63 and the inclined surface B64, the horizontal thrust of the push plate 62 is converted into a force that drives the lifting seat 11 to move upward. As a result, the lifting seat 11, with the blade corner, rises along the axial direction of the mounting hole 10 through the support block 17. After the support block 17 is separated from the mounting hole 10, under the action of the blade corner pressure and its own gravity, the lower part of the support block 17 makes contact with the lower tire body 8 and stops rising. As the lifting seat 11 moves upward, the support block 17 moves to the outer side of the lifting seat 11 in the horizontal direction through the cooperation of the slider 15 and the slot 14 until the blade corner contacts the roller 16. Under the action of its own gravity and the upward movement of the lifting seat 11, the support block 17 continues to move to the outer side until the blade corner is pushed above the positioning baffle 9 and stops.

[0042] Then, the rodless cylinder 1 is activated to drive the moving plate 2 and the material-pushing component 3 to move away from the stop 5. Under its own weight, the material-pushing component 3 drives the slider 42 to move diagonally downward along the inclined slide 41. When the slider 42 is at the bottom of the inclined slide 41, the material-pushing plate 31 falls to one side of the blade corner. The rodless cylinder 1 continues to drive the moving plate 2 to move to the left, pushing the blade corner to the idler roller conveyor outside the lower tire body, completing one operation of the blade corner disengaging from the press.

[0043] When the blank of the blade corner has not entered the lower body 8, the rodless cylinder 1 is activated to drive the moving plate 2 and the material feeding component 3 to move towards the stop 5. When the fixed plate 32 contacts the bearing 52, it cannot move outward, but the moving plate 2 still moves outward. At this time, the slider 42 moves along the inclined slide groove 41, and then the slider 42 drives the fixed plate 32 and the material feeding plate 31 to move upward, thereby lifting the material feeding component 3 and preventing the blank of the blade corner conveyed by the roller from entering the lower body. At this time, part of the blank of the blade corner enters the lower body.
