Description

Technical Field

[0001] This utility model relates to the technical field of punching devices, specifically a punching device for shell production. Background Technology

[0002] A punching device is a mechanical device specifically designed to quickly and accurately punch specific shapes such as round holes, square holes, and chamfered holes in plastic sheets or pre-formed plastic shells. It typically consists of a punching platform, a positioning and clamping mechanism, a stamping mechanism, and an external controller. It can perform single-piece or batch punching, meeting the high-efficiency processing needs of plastic shells in industries such as electronics, home appliances, and automobiles.

[0003] Existing punching devices for shell production lack automatic loading and unloading mechanisms. The plastic shell to be processed needs to be placed manually in the middle of the punching platform, and then the plastic shell is clamped and positioned by the positioning and clamping mechanism. This method is cumbersome and laborious, and the workers' hands need to be extended directly under the punching mechanism, which is dangerous. Therefore, a punching device for shell production is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a punching device for shell production, so as to solve the problem that some existing punching devices for shell production lack automatic loading and unloading mechanisms.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A punching device for shell production includes a worktable, a punching mechanism, a conveying mechanism, a limiting mechanism, and a locking mechanism. The punching mechanism is mounted on the upper surface of the worktable. The conveying mechanism includes a conveyor belt assembly located above the worktable. Two support blocks are fixedly connected to the lower surface of the outer shell of the conveyor belt assembly. A set of compression springs installed on the lower end of the outer shell of the conveyor belt assembly is provided between the two support blocks. A pair of limiting blocks are fixedly connected to the left and right sides of the outer shell of the conveyor belt assembly. Limiting frames that slidably connect to the outer sides of each limiting block and fit against the upper surface of the worktable are slidably connected to it. The inner side of each frame is provided with a pair of limiting shafts passing through the limiting frame. The upper surface of the worktable is provided with a limiting mechanism. The limiting mechanism includes two support platforms located on the left and right sides of the conveyor belt assembly and fixedly connected to the worktable. The opposite sides of the two support platforms are provided with a first multi-stage electric telescopic rod fixedly connected to the worktable. The piston rod of the first multi-stage electric telescopic rod is fixedly connected to a transmission block located in the through groove of the support platform and slidably connected to the support platform. The upper surface of the transmission block is fixedly connected to a limiting plate slidably connected to the support platform. An infrared rangefinder is fixedly connected to the upper surface of the limiting plate on the right side.

[0007] Preferably, the upper surface of the worktable is provided with a locking mechanism. The locking mechanism includes two pairs of limiting rails fixedly connected to the worktable. Between each pair of limiting rails, there is a second multi-stage electric telescopic rod fixedly connected to the worktable. The piston rod of the second multi-stage electric telescopic rod is fixedly connected to a sliding seat that is slidably connected to a pair of limiting rails. A dual-axis motor is fixedly connected inside each sliding seat. The two output shafts of the dual-axis motor are fixedly connected to screws that are rotatably connected to the sliding seat. The outer side of each screw is threaded with a screw block that is slidably connected to the sliding seat. A locking plate is fixedly connected to the upper surface of each screw block.

[0008] Preferably, the locking mechanisms are symmetrically distributed, the sliding seats are located on the opposite sides of the two support platforms, the locking plates are all bent plates, the lower ends of the bent portions of the locking plates are all inclined surfaces, and the height of the bent portions of the locking plates gradually decreases towards the conveyor belt assembly.

[0009] Preferably, each limiting shaft is composed of a hexagonal limiting part, a sliding connecting part, and a threaded connecting part that are fixedly connected in sequence. The threaded connecting part of each limiting shaft is threadedly connected to the worktable, and the sliding connecting part of each pair of limiting shafts passes through the limiting block and is slidably connected to the limiting block.

[0010] Preferably, the hexagonal limiting portions of the limiting shaft are all located within the grooves of the limiting frame, the upper surfaces of the hexagonal limiting portions of the limiting shaft are all aligned with the upper surfaces of the limiting frame, and the upper surfaces of the limiting frame are all aligned with the upper surfaces of the supporting platform.

[0011] Preferably, the stamping mechanism consists of a mounting bracket and a hydraulic punching mechanism. The hydraulic punching machine of the stamping mechanism is located directly above the conveyor belt assembly. The conveyor belt assembly consists of a housing, a drive shaft, a driven shaft, a conveyor belt, and a drive motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the device, with its conveyor belt assembly, compression spring, support platform, and locking plate, allows the conveyor belt assembly to be supported by the compression spring, ensuring it is higher than the support platform. This enables the conveyor belt assembly to smoothly move the plastic shell back and forth. Simultaneously, the locking plate, which can move left and right, presses the conveyor belt assembly downward, causing the plastic shell to fall onto the support platform. The support platform supports the plastic shell, and the laterally movable limiting plate limits its movement in the left and right directions, while the forward-backward movable locking plate limits its movement in the forward-backward direction. This precise positioning of the plastic shell facilitates punching by the stamping mechanism. After punching, the plastic shell can continue to be transported backward by the conveyor belt assembly. This method is convenient, labor-saving, and safer for workers. Attached Figure Description

[0025] A punching device for shell production includes a worktable 1, a punching mechanism 2, a conveying mechanism 3, a limiting mechanism 4, and a locking mechanism 5. The punching mechanism 2 is mounted on the upper surface of the worktable 1, and the conveying mechanism 3 is located on the upper surface of the worktable 1. The conveying mechanism 3 includes a conveyor belt assembly 31 located above the worktable 1. Two support blocks 32 are fixedly connected to the lower surface of the outer shell of the conveyor belt assembly 31. A set of compression springs 33 installed on the lower surface of the outer shell of the conveyor belt assembly 31 is provided between the two support blocks 32. A pair of limiting blocks 34 are fixedly connected to the left and right sides of the outer shell of the conveyor belt assembly 31. Limiting frames 35 that fit against the upper surface of the worktable 1 are slidably connected to the outer sides of the limiting blocks 34. The inner side of the limiting frame 35... Each part is provided with a pair of limiting shafts 36 passing through the limiting frame 35. The upper end face of the worktable 1 is provided with a limiting mechanism 4. The limiting mechanism 4 includes two support platforms 41 located on the left and right sides of the conveyor belt assembly 31 and fixedly connected to the worktable 1. The back side of the two support platforms 41 is provided with a first multi-stage electric telescopic rod 42 fixedly connected to the worktable 1. The piston rod of the first multi-stage electric telescopic rod 42 is fixedly connected to a transmission block 43 located in the through groove of the support platform 41 and slidably connected to the support platform 41. The upper end face of the transmission block 43 is fixedly connected to a limiting plate 44 slidably connected to the support platform 41. The upper end face of the limiting plate 44 on the right side is fixedly connected to an infrared rangefinder 45.

[0026] The upper surface of the workbench 1 is provided with a locking mechanism 5. The locking mechanism 5 includes two pairs of limiting rails 51 fixedly connected to the workbench 1. Between each pair of limiting rails 51, there is a second multi-stage electric telescopic rod 52 fixedly connected to the workbench 1. The piston rod of the second multi-stage electric telescopic rod 52 is fixedly connected to a sliding seat 53 that is slidably connected to a pair of limiting rails 51. A dual-axis motor 54 is fixedly connected inside the sliding seat 53. The two output shafts of the dual-axis motor 54 are fixedly connected to screws 55 that are rotatably connected to the sliding seat 53. The outer sides of each of the 5 are threaded with screw blocks 56 that slide in connection with the sliding seats 53. Each screw block 56 has a locking plate 57 fixedly connected to its upper end. The locking plates 57 can clamp and position the plastic housing in the front-to-back direction. The locking mechanisms 5 are symmetrically distributed, with the sliding seats 53 located on the opposite sides of the two support platforms 41. The locking plates 57 are all bent plates, with the lower ends of the bent portions of the locking plates 57 being inclined surfaces. The height of the bent portions of the locking plates 57 gradually decreases towards the conveyor belt assembly 31. The bending of the locking plates 57... The partially inclined lower end face can apply a downward force to the outer shell of the conveyor belt assembly 31; each limiting shaft 36 is composed of a hexagonal limiting part, a sliding connection part, and a threaded connection part that are fixedly connected in sequence. The threaded connection part of each limiting shaft 36 is threadedly connected to the worktable 1. The sliding connection part of each pair of limiting shafts 36 passes through the limiting block 34 and is slidably connected to the limiting block 34. The limiting shafts 36 can make the limiting block 34 in the limiting frame 35 slide downward stably; the hexagonal limiting parts of each limiting shaft 36 are located in the groove of the limiting frame 35. The upper surface of the hexagonal limiting part of the limiting shaft 36 is aligned with the upper surface of the limiting frame 35, and the upper surface of the limiting frame 35 is aligned with the upper surface of the support platform 41. The support platform 41 can support the plastic shell. The stamping mechanism 2 consists of a mounting bracket and a hydraulic punching mechanism. The hydraulic punching machine of the stamping mechanism 2 is located directly above the conveyor belt assembly 31. The conveyor belt assembly 31 consists of a shell, a drive shaft, a driven shaft, a conveyor belt, and a drive motor. The stamping mechanism 2 can smoothly complete the punching after the plastic shell is accurately positioned.

[0027] Workflow: Before use, install the workbench 1 in a suitable position and connect the power supply to the device. The device is equipped with an external controller, which is electrically connected to the stamping mechanism 2, the conveyor belt assembly 31, the first multi-stage electric telescopic rod 42, the second multi-stage electric telescopic rod 52, and the dual-axis motor 54. Manual operation of the external controller allows adjustment of the operating status of the stamping mechanism 2, the conveyor belt assembly 31, the first multi-stage electric telescopic rod 42, the second multi-stage electric telescopic rod 52, and the dual-axis motor 54. All of the above are existing technologies. Before use, the operator inputs the length and width of the plastic shell to be processed through the external controller and ensures that both the first multi-stage electric telescopic rod 42 and the second multi-stage electric telescopic rod 52 are fully retracted, allowing the screw block to... All 56 are positioned far from the second multi-stage electric telescopic rod 52. When using this device, the operator stands in front of the workbench 1, starts the conveyor belt assembly 31 via the external controller, and places the plastic shell to be processed on the conveyor belt of the conveyor belt assembly 31. The conveyor belt assembly 31, supported by the compression spring 33, can move the plastic shell from front to back. When the infrared rangefinder 45 detects a sudden decrease in distance data, it indicates that the plastic shell is blocking the infrared rangefinder 45. At this time, the external controller can automatically stop the conveyor belt assembly 31 and automatically extend both second multi-stage electric telescopic rods 52 completely. The second multi-stage electric telescopic rods 52 drive the sliding seat 53, which is limited by the limiting rail 51, to move in the left and right directions. A groove is provided on the lower side so that the sliding seat 53 will not interfere with the first multi-stage electric telescopic rod 42 when it moves. The left and right movement of the sliding seat 53 can bring the locking plate 57 closer to the conveyor belt assembly 31. The lower end face of the bent part of the locking plate 57 can apply a downward force to the outer shell of the conveyor belt assembly 31, compressing the compression spring 33 and causing the limiting block 34 in the limiting frame 35 to slide stably downward under the limitation of the limiting shaft 36, so that the lower end face of the support block 32 is in contact with the worktable 1. At this time, the upper end face of the conveyor belt assembly 31 is aligned with the upper end face of the support platform 41. Since the conveyor belt assembly 31 is relatively narrow, the left and right edges of the lower end face of the plastic shell rest on the support platform 41. The support platform 41 can support the plastic shell, and then the external controller... The system can automatically extend two first-stage electric telescopic rods 42 synchronously. An external controller can extend the first-stage electric telescopic rods 42 a specific distance based on the width of the plastic housing. The first-stage electric telescopic rods 42 drive two transmission blocks 43 to move closer together, which in turn causes two limiting plates 44 to move closer together. The limiting plates 44 can clamp and position the plastic housing in the left-right direction. Then, the external controller can automatically start two dual-axis motors 54 synchronously. The external controller can rotate the dual-axis motors 54 a specific number of revolutions based on the length of the plastic housing. The dual-axis motors 54 drive the screw 55, which is limited by the sliding seat 53, to rotate. This causes the screw block 56 to move the locking plate 57 in the front-back direction, bringing the locking plate 57 closer to the second-stage electric telescopic rod 52.The locking plate 57 can clamp and position the plastic shell in the front-to-back direction, thus locking the plastic shell. At this time, the external controller can adjust the stamping mechanism 2 to punch holes in the plastic shell using a hydraulic punching machine. The stamping mechanism 2 is existing equipment and can smoothly complete the punching after the plastic shell is accurately positioned. After punching is completed, the external controller can automatically reverse the dual-axis motor 54, retract the first multi-stage electric telescopic rod 42 and the second multi-stage electric telescopic rod 52, and restart the conveyor belt assembly 31 to position and punch the next plastic shell. This device can support the conveyor belt assembly 31 with the compression spring 33, making the conveyor belt assembly 31 higher than the support platform 41. The conveyor belt assembly 31 smoothly moves the plastic shell back and forth, while the locking plate 57, which can move left and right, presses the conveyor belt assembly 31 downward, causing the plastic shell to fall onto the support platform 41. The support platform 41 supports the plastic shell, and the left and right movable limiting plate 44 limits the plastic shell in the left and right directions, while the front and back movable locking plate 57 limits the plastic shell in the front and back directions. This allows for accurate positioning of the plastic shell, facilitating punching by the stamping mechanism 2. After punching, the plastic shell can continue to be transported backward by the conveyor belt assembly 31. This method is convenient, labor-saving, and safer for workers.
