Description

Technical Field

[0001] The utility model relates to the technical field of stamping processing of metal accessories, in particular to a stamping die for processing harvester spare parts. Background Art

[0002] At present, many spare parts in harvesters can be made by stamping. For example, the external covering parts of harvesters, such as hoods and guards, are usually made of steel plates by stamping. Internal structural parts, such as the side walls and bottoms of fuel tanks and water tanks, are usually made of thin steel plates by stamping. After stamping, these spare parts can improve their strength, rigidity and fatigue resistance to meet the use requirements of harvesters.

[0003] The applicant found that the existing multi-station stamping dies for harvester spare parts are inconvenient when workers take the workpieces because the lower die is located below the upper die. It also poses certain safety hazards. Once the upper die moves down due to improper operation, it will cause serious damage to the workers' hands.

[0004] Therefore, in order to solve the above problems, the applicant proposed a stamping die for processing harvester parts to solve the problems. Utility Model Content

[0005] The utility model provides a stamping die for processing spare parts of harvesters, which solves the problem that when workers take workpieces in the existing multi-station stamping die for harvester spare parts, the lower die is located below the upper die, which is not only inconvenient in terms of space efficiency, but also has certain safety hazards. Once the upper die moves downward due to misoperation, it will cause serious damage to the hands of the workers.

[0006] To solve the above technical problems, the utility model provides a stamping die for processing harvester spare parts, including a die table, a movable seat is slidably installed on the top of the die table and a stand is fixed, four lower die grooves are installed on the top of the movable seat, a lifting plate is installed on the top of the stand through a hydraulic rod, a punching die corresponding to the lower die groove is installed on the bottom of the lifting plate, the lifting plate and the movable seat are connected with a driving part, the driving part includes a tooth plate fixed on the top of the lifting plate, the tooth plate is meshed with a gear 1 rotatably installed on the top of the stand, a bidirectional screw rod is connected to the rotating shaft of the gear 1 through a synchronous belt, and moving blocks are installed on opposite threads at both ends of the bidirectional screw rod, and the moving block and the moving seat are rotatably connected to the two ends of the driving rod.

[0007] Preferably, the gear 1 is rotatably connected to two vertical plates fixed on the top of the stand, and one vertical plate is rotatably connected to the gear 2, and the gear 2 meshes with the gear 1 and plays a limiting role.

[0008] Preferably, two limiting sliding blocks fixed at the bottom of the movable seat slide in the slideway at the top of the mold table, and rubber pads are bonded on both sides of the limiting sliding blocks.

[0009] Preferably, six rows of ball grooves are provided at the bottom of the movable seat, and steel balls are rollingly connected in the ball grooves, and the steel balls are in contact with the top surface of the mold table.

[0010] Preferably, four guide rods are fixed at equal intervals on the top of the lifting plate, and the guide rods slide up and down in the through holes of the stand.

[0011] Preferably, a buffer block is slidably connected to the outside of the guide rod, and a buffer spring is connected to the bottom of the buffer block and the top surface of the stand.

[0012] Preferably, the movable seat and the lower die groove as well as the lifting plate and the punching die are all designed to be detachable.

[0013] Compared with the related art, the stamping die for processing harvester parts provided by the utility model has the following beneficial effects:

[0014] 1. The utility model uses the driving part. When the workpiece is placed for stamping, the hydraulic rod drives the lower level of the lifting plate, so that the toothed plate passing through the stand moves downward and drives the gear to rotate. At this time, the synchronous belt passing through the stand will drive the bidirectional screw to rotate, so that the two moving blocks move and move away, so that the driving rod rotates and pulls the moving seat to the innermost processing position. After the processing is completed, the toothed plate moves up and meshes with the gear again to push the moving seat out to take out the workpiece. In this way, the space will not be limited when placing and taking it, which is very convenient. At the same time, it also avoids the situation where the punching die accidentally drops and presses the hand, which is very practical.

[0015] 2. In the optimized design of the mobile seat, the limit slider facilitates the displacement of the mobile seat. At the same time, during processing and resetting, both ends of the limit slider will contact and fit with the two ends of the slideway. At this time, the rubber pad can play a good protective buffering effect, and the steel ball not only allows the mobile seat to move better, but also provides a good supporting effect to avoid damage to the limit slider caused by excessive punching pressure.

[0016] 3. In the optimized design of the stamping structure, the utility model has a detachable design of the lower die groove and the die, which is easy to maintain and clean, and the guide rod can play a guiding role to improve the stamping stability. At the same time, during stamping, the rod head on the top of the guide rod will contact the buffer block and exert pressure on it. At this time, the buffer spring is compressed and deformed, thereby achieving a good buffering effect, avoiding damage to the workpiece and the mold, and further improving the protection effect.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Depend on Figure 1-7 As shown in the figure, the utility model includes a mold table 1, a movable seat 2 is slidably installed on the top of the mold table 1 and a stand 11 is fixed, four lower mold grooves 3 are installed on the top of the movable seat 2, a lifting plate 5 is installed on the top of the stand 11 through a hydraulic rod 4, a punch 6 corresponding to the lower mold groove 3 is installed at the bottom of the lifting plate 5, the lifting plate 5 and the movable seat 2 are connected with a driving part 7, the driving part 7 includes a tooth plate 71 fixed on the top of the lifting plate 5, the tooth plate 71 is meshed with a gear 72 rotatably installed on the top of the stand 11, a bidirectional screw rod 74 is connected to the rotating shaft of the gear 72 through a synchronous belt 73, a moving block 75 is installed on the opposite threads at both ends of the bidirectional screw rod 74, and the moving block 75 and the two ends of the moving seat 2 are rotatably connected with the driving rod 76.

[0027] As mentioned above, through the driving part 7, the lifting plate 5 and the moving seat 2 are staggered with each other in the initial position. When the workpiece is placed for stamping, the hydraulic rod 4 drives the lower level of the lifting plate 5, so that the toothed plate 71 passing through the stand 11 moves downward and drives the gear 72 to rotate. At this time, the synchronous belt 73 passing through the stand 11 will drive the bidirectional screw rod 74 to rotate, so that the two moving blocks 75 move and move away, thereby causing the driving rod 76 to rotate and pull the moving seat 2. When the toothed plate 71 and the gear 72 lose engagement, the moving seat 2 slides to the innermost processing position, and the die 6 is close to the top surface of the lower die groove 3. Then the die 6 continues to move downward into the lower die groove 3 to complete the stamping processing of the harvester spare parts. After the processing is completed, the toothed plate 71 moves up and re-engages with the gear 72 to push the moving seat 2 out to take out the workpiece. In this way, the space will not be limited when placing and taking it, which is very convenient. At the same time, it also avoids the situation where the die 6 accidentally drops and presses the hand, which is very practical.

[0028] Gear 1 72 is rotatably connected to two vertical plates fixed on the top of the stand 11, and one of the vertical plates is rotatably connected to gear 2 77, which meshes with gear 1 72 and plays a limiting role.

[0029] As mentioned above, since the tooth plate 71 and gear 1 72 lose engagement during stamping, gear 2 77 engages with gear 1 72, and gear 2 77 is set to have a certain rotational resistance, which prevents gear 1 72 from rotating easily, avoiding accidental rotation of gear 1 72 when losing engagement, causing the punch 6 to be unable to enter the lower die groove 3, thereby improving working stability.

[0030] Two limit sliders 21 fixed at the bottom of the moving seat 2 slide in the slideway at the top of the mold table 1, and rubber pads 22 are bonded on both sides of the limit sliders 21. Six rows of ball grooves are provided at the bottom of the moving seat 2, and steel balls 23 are rollingly connected in the ball grooves, and the steel balls 23 are in contact with the top surface of the mold table 1.

[0031] As mentioned above, in the optimized design of the moving seat 2, the limit slider 21 facilitates the displacement of the moving seat 2. At the same time, during processing and resetting, both ends of the limit slider 21 will contact and fit with the two ends of the slideway. At this time, the rubber pad 22 can play a good protective buffering effect, and the steel ball 23 not only allows the moving seat 2 to move better, but also provides a good supporting effect to avoid damage to the limit slider 21 caused by excessive punching pressure.

[0032] Four guide rods 8 are fixed at equal distances on the top of the lifting plate 5. The guide rods 8 slide up and down in the through holes of the stand 11. A buffer block 81 is slidably connected to the outside of the guide rod 8. The bottom of the buffer block 81 is connected to the top surface of the stand 11 with a buffer spring 82. The movable seat 2 and the lower die groove 3 as well as the lifting plate 5 and the die 6 are all detachable in design.

[0033] As mentioned above, in the optimized design of the stamping structure, the detachable design of the lower die groove 3 and the die 6 is convenient for maintenance and cleaning, and the guide rod 8 can play a guiding role to improve the stamping stability. At the same time, during stamping, the rod head on the top of the guide rod 8 will contact the buffer block 81 and exert pressure on it. At this time, the buffer spring 82 is compressed and deformed, thereby playing a good buffering effect, avoiding damage to the workpiece and the mold, and further improving the protection effect.
