A kind of edge pressing tool for construction site guardrail production

Abstract

This utility model relates to the field of guardrail edge pressing technology, and in particular to an edge pressing fixture for the production of construction site guardrails. It includes a base, a frame, and a support. The upper rear side of the outer wall of the base is fixedly connected to the frame, and an electric telescopic rod is fixedly connected to the upper inner wall of the frame. The output end of the electric telescopic rod is fixedly connected to the upper support. This edge pressing fixture for construction site guardrail production, through a workstation adjustment structure, starts a first motor that drives a threaded rod to rotate within the base via a bearing. The rotation of the threaded rod causes a slider to slide to the right on the outer wall of a first sliding rod. The slider is restricted to sliding left and right by the first sliding rod, which in turn drives the lower support to move to the right. After edge pressing the guardrail, the motor ultimately moves the lower support to press the subsequent mold. During subsequent guardrail edge pressing, the pressed mold can be retrieved, reducing downtime and improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of edge pressing technology for guardrails, specifically an edge pressing tool for the production of construction site guardrails. Background Technology

[0002] A fence is a barrier structure used for isolation, protection, or demarcation of areas. It is usually made of metal (such as steel pipes or wire mesh), plastic, wood, or composite materials. The edge-pressing tool used in the production of construction site guardrails is usually a metal processing mold, mainly used to bend, flatten, or reinforce the edges of guardrail panels.

[0003] For example, a guardrail edge-pressing fixture with application announcement number "CN108246858A" has a simple structure, is easy to operate, and has low assembly costs, which helps reduce production costs and maintain enterprise development. However, the above-mentioned workstation is singular. After pressing the edge of the fence with the edge-pressing shaft, the device needs to stop working during the collection process, resulting in a long downtime. At the same time, during the replacement of the edge-pressing shaft, the operator needs to rotate the mounting base back and forth to disengage it from the cylinder shaft and replace it. Moreover, the corresponding edge-pressing groove position is fixed, which is inconvenient for replacement and the operation is relatively cumbersome. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of single workstation, long downtime and low production efficiency when the edge of the fence is pressed by the edge pressing shaft, and the need for the device to stop working during the collection process after pressing the edge. In addition, the replacement of the edge pressing shaft requires the operator to rotate the mounting base back and forth to disengage it from the cylinder shaft and replace it. Furthermore, the fixed position of the edge pressing groove makes it inconvenient to replace and the operation is cumbersome. Therefore, this utility model proposes an edge pressing tool for the production of construction site guardrails.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a pressing tool for the production of construction site guardrails, including a base, a frame, and supports. The upper rear side of the outer wall of the base is fixedly connected to the frame. An electric telescopic rod is fixedly connected to the upper inner wall of the frame. The output end of the electric telescopic rod is fixedly connected to the upper support. The lower inner wall of the lower support is movably connected to multiple ball bearings. The lower outer wall of the ball bearings fits against the base. The support has a mold limiting structure inside. The inner wall of the base has a work position adjustment structure. The inner walls of the multiple supports are respectively inserted into the upper mold and the lower mold.

[0006] Preferably, the mold limiting structure includes a pull rod, the outer wall of the pull rod is provided with a spring, the end of the pull rod is fixedly connected to a locking block, the two ends of the spring are respectively fixedly connected to a support and a locking block, the outer walls of the plurality of locking blocks are respectively pressed against the upper mold and the lower mold, the outer walls of the locking blocks are slidably connected to a second sliding rod, and the two ends of the second sliding rod are fixedly connected to the support.

[0007] Preferably, the outer wall of the tie rod is slidably connected to the support, and a third sliding rod is fixedly connected to the upper end of the outer wall of the support.

[0008] Preferably, the outer wall of the third slide rod is slidably connected to the plate, and the end of the plate is fixedly connected to the frame.

[0009] Preferably, the workstation adjustment structure includes a motor, a threaded rod is fixedly connected to the end of the motor output shaft, the outer wall of the threaded rod is rotatably connected to a bearing base, the two ends of the threaded rod are threadedly connected to a slider, the inner wall of the slider is slidably connected to a first slide rod, the two ends of the first slide rod are fixedly connected to a base, and the outer walls of the plurality of sliders are fixedly connected to a support.

[0010] Preferably, the outer wall of the motor is fixedly connected to the base via a bracket.

[0011] The present invention proposes a pressing tool for the production of construction site guardrails. The beneficial effects are as follows: through the mold limiting structure, pulling the upper pull rod outward causes the locking block to slide outward on the outer wall of the second slide rod. The locking block is restricted by the second slide rod and can only move laterally. The outward movement of the locking block compresses the spring. After the locking block disengages from the locking groove on the upper mold, the upper mold is pulled out from the support and the corresponding pressing mold is inserted. The pulling rod drives the locking block to move to limit or release the upper and lower molds, which facilitates the replacement of the upper and lower molds and simplifies the operation process of replacing the upper or lower mold.

[0012] Through the workstation adjustment structure, the first motor starts and drives the threaded rod to rotate in the base through the bearing. The rotation of the threaded rod drives the slider to slide to the right on the outer wall of the first slide rod. The slider is restricted by the first slide rod and can only slide left and right. Then, the slider drives the support at the lower end to move to the right. After pressing the edge of the fence, the motor finally drives the lower support to move to press the edge of the subsequent mold. When pressing the edge of the subsequent fence, the mold after pressing can be collected, reducing the downtime of the work. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-6 In this embodiment, a pressing tool for the production of construction site guardrails includes a base 3, a frame 4 and a support 7. The upper rear side of the outer wall of the base 3 is fixedly connected to the frame 4, and an electric telescopic rod 5 is fixedly connected to the upper side of the inner wall of the frame 4. The electric telescopic rod 5 is model Thomson Electrak HD and has a self-locking function. The output end of the electric telescopic rod 5 is fixedly connected to the upper support 7. The lower end of the inner wall of the lower support 7 is movably connected to multiple balls 11. The balls 11 can move within the support 7. The lower end of the outer wall of the balls 11 fits against the base 3. The support 7 is equipped with a mold limiting structure 2. The inner wall of the base 3 is provided with a work position adjustment structure 1. The inner walls of multiple supports 7 are respectively inserted into the upper mold 10 and the lower mold 9. The outer wall of the pull rod 201 is slidably connected to the support 7. The pull rod 201 can slide inside the support 7. The upper end of the outer wall of the upper support 7 is fixedly connected with a third sliding rod 6. The outer wall of the third slide rod 6 is slidably connected to the plate 8. The support 7 is restricted by the third slide rod 6 to move only up and down. The end of the plate 8 is fixedly connected to the frame 4. The outer wall of the motor 101 is fixedly connected to the base 3 through the bracket. The lower support 7 and the front side of the base 3 are both fixed with cover plates by bolts, which can realize the installation of internal parts. At the same time, the cover plates can be removed to inspect the internal parts when needed.

[0016] See attached document Figure 1-5 The mold limiting structure 2 includes a pull rod 201, and a spring 203 is provided on the outer wall of the pull rod 201. The spring force coefficient of the spring 203 is determined according to actual needs and meets the working requirements. A locking block 202 is fixedly connected to the end of the pull rod 201, and the two ends of the spring 203 are fixedly connected to the support 7 and the locking block 202 respectively. The outer walls of multiple locking blocks 202 are respectively abutted against the upper mold 10 and the lower mold 9. The outer walls of the locking blocks 202 are slidably connected to the second slide rods 204. The locking blocks 202 are restricted to slide laterally by the second slide rods 204. The two ends of the multiple second slide rods 204 are fixedly connected to the support 7.

[0017] See attached document Figure 1-2 6: The workstation adjustment structure 1 includes a motor 101, which is a servo motor. The output shaft of the motor 101 is fixedly connected to a threaded rod 102. Both ends of the threaded rod 102 are rotatably connected to the bearing base 3. The motor 101 can drive the threaded rod 102 to rotate within the base 3 through the bearing. The outer wall of the threaded rod 102 is threadedly connected to the slider 103, the inner wall of the slider 103 is slidably connected to the first sliding rod 104, the slider 103 is restricted by the first sliding rod 104 to slide only laterally, the two ends of the first sliding rod 104 are fixedly connected to the base 3, and the outer wall of the slider 103 is fixedly connected to the support 7.

[0018] Working principle: Replacement of edge-pressing molds for construction site guardrail production: When it is necessary to produce edge pressing for the construction site guardrail, pull the upper pull rod 201 outward to drive the locking block 202 to slide outward on the outer wall of the second slide rod 204. The locking block 202 is restricted by the second slide rod 204 and can only move laterally. The outward movement of the locking block 202 compresses the spring 203 (if there is a lot of vibration during the edge pressing process, a spring damper can be installed in the spring 203 to reduce the impact of vibration on the spring). After the locking block 202 disengages from the slot on the upper mold 10, the upper mold 10 is pulled out from the support 7 and the corresponding edge pressing mold is inserted. Then, the pull rod 102 is released, and the spring 203 is released to push the locking block 202 to lock in the upper mold 10 after replacement. In this way, the upper mold 10 can be limited. This movement can be used to replace the upper mold 10. Then, following the same working method as described above, the lower rod 201 is pulled outwards in sequence to replace the two lower molds 9. The upper mold 10 and the lower mold 9 are replaced, which can be used for edge pressing production of fences with different needs. The upper mold 10 and the lower mold 9 can be selected according to the required edge pressing angle and shape.

[0019] Construction site fence edge pressing and work position adjustment work: After replacing the upper mold 10 and the lower mold 9, place the fence edge pressing position on the lower mold 9 on the right end, and then place the subsequent fence edge pressing position on the lower mold 9 on the left end. Connect the external power supply of the electric telescopic rod 5. The electric telescopic rod 5 starts and drives the upper support 7 to move downward. The upper support 7 drives the third slide rod 6 to slide downward on the outer wall of the plate 8. The upper support 7 can only move up and down due to the restriction of the third slide rod 6. The upper support 7 drives the upper mold 9 to descend and cooperate with the lower mold 9 to perform the edge pressing work on the fence. After the edge pressing is completed, control the electric telescopic rod 5 to drive the upper mold 9 to reset. Then the external power supply of the first motor 101 is connected. The first motor 101 starts and drives the threaded rod 102 to rotate in the base 3 through the bearing. The rotation of the threaded rod 102 drives the slider 103 to slide to the right on the outer wall of the first slide rod 104. The slider 103 is restricted by the first slide rod 104 and can only slide left and right. Then the slider 103 drives the support 7 at the lower end to move to the right. Meanwhile, multiple balls 11 roll within the lower support 7 due to friction. The balls 7 provide support for the lower support 7. When the lower mold 9 on the left aligns with the upper mold 10, the motor 101 stops rotating. The motor 101 is a servo motor capable of rotating at a fixed angle and has a self-locking characteristic. This allows the lower support 7 to be transported to a fixed position. Then, in the same manner as described above, the edge pressing work is performed on the subsequent fence. At this time, the workers can collect the edge-pressed fence and place it into the fence to be pressed. Then, the motor 101 is reversed so that the lower mold 9 on the right aligns with the upper mold 10 again to perform the subsequent edge pressing work. In this way, the edge-pressed fence can be collected during the fence edge pressing process, reducing work downtime.
