Detailed Implementation

[0029] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0030] like Figure 1As shown, the present invention provides a mold for manufacturing elevator guide rail pressure plates, including a support frame 1. The support frame 1 is stably installed on the work site to ensure its level and stability. A lower mold 2 is fixedly connected to the top of the support frame 1. One end of the lower mold 2 is embedded with a drilling hole 21, which extends downward and penetrates the top area of ​​the support frame 1 to facilitate the movement of the subsequent drilling bit 154. A guide rod 3 is fixedly connected to the top of the support frame 1. A top plate 4 is fixedly connected to the top of the guide rod 3. A hydraulic cylinder 5 is fixedly connected to the bottom of the top plate 4. The top plate 4 is used to provide installation space for the hydraulic cylinder 5. The hydraulic cylinder 5 is used to provide driving force to the guide plate 6 and drive the guide plate 6 to move up and down to adjust its position. The bottom of the hydraulic cylinder 5 is fixedly connected to the top of the guide plate 6. The four corners of the guide plate 6 are slidably connected to the guide rod 3 to improve the stability of the guide plate 6 when it moves. Among them, a controller is provided on the support frame 1. The controller is electrically connected to the electrical components to facilitate subsequent control of the electrical components. Specifically, a safety light curtain and physical guardrail are installed around the support frame 1. When the light curtain detects that a person or foreign object has entered the danger zone, the equipment will immediately stop moving.

[0031] like Figure 1-5 As shown in this embodiment, the bottom of the guide plate 6 is fixedly connected to a receiving frame 7. The surface of the receiving frame 7 is provided with an organic glass observation window, which facilitates subsequent observation of the inside of the receiving frame 7 through the organic glass window. During operation, the receiving frame 7 moves downward and wraps the lower mold 2 inside. The top of the guide plate 6 is fixedly connected to a first driver 8, a second driver 10, and a third driver 12, which are used to control the movement of multiple sets of pressing plates respectively, so that the raw material plate can be pressed and formed in segments. Among them, the bottom telescopic end of the first driver 8 is fixedly connected to the first pressing plate 9, the bottom telescopic end of the second driver 10 is connected to the second pressing plate 11, the bottom telescopic end of the third driver 12 is connected to the third pressing plate 13, the first pressing plate 9, the second pressing plate 11 and the third pressing plate 13 form an upper mold, and the first pressing plate 9, the second pressing plate 11 and the third pressing plate 13 are set in the receiving frame 7. In the process of making the pressure guide plate, the raw material plate is placed on the lower mold 2, and then the hydraulic cylinder 5 is controlled to drive the guide plate 6 to move downward. The guide plate 6 drives the receiving frame 7 to move downward to wrap the lower mold 2. Then the movement of the hydraulic cylinder 5 is stopped. The second driver 10 is pre-controlled to move the second pressing plate 11 downward to squeeze the middle area of ​​the raw material plate, so that the middle area of ​​the raw material plate is pre-compressed and bent to form a Z-shaped blank. Then the first driver 8 drives the first pressing plate 9 downward to squeeze and fix it with the left area of ​​the raw material plate. The third driver 12 drives the third pressing plate 13 downward to squeeze the right end area of ​​the raw material plate, so that the left and right ends of the raw material plate are squeezed and form pressure guide plates.

[0032] like Figure 1-4 As shown in this embodiment, the first pressing plate 9 is provided with a receiving component 14, and the first pressing plate 9 is provided with a through hole 21, and the through hole 21 on the first pressing plate 9 is located directly above the through hole 21 on the lower mold 2.

[0033] like Figure 2-5 As shown in this embodiment, the support frame 1 has a drive assembly 15 at its bottom. The drive assembly 15 includes an L-shaped frame 151. The top of the L-shaped frame 151 is fixedly connected to the bottom of the support frame 1. An electric push rod 152 is fixedly connected to the bottom of the L-shaped frame 151. The moving end of the electric push rod 152 is slidably connected to the upper end of the L-shaped frame 151. The telescopic end of the electric push rod 152 is fixedly connected to the drive motor 153. The output shaft of the drive motor 153 is fixedly connected to the drilling bit 154. The drilling bit 154 is hollow inside. A return spring 155 is fixedly connected to the bottom of the drilling bit 154. The top of the return spring 155 is fixedly connected to the pressing rod 156. The drilling bit 154 is coaxially arranged with the drilling hole 21. The drilling bit 154 is located directly below the drilling hole 21. Specifically, the extrusion rod 156 is a magnet, and the upper end of the extrusion rod 156 and the bottom of the magnet 149 are magnetically repulsive, so that when the extrusion rod 156 moves upward, the extrusion rod 156 pushes the magnet 149 to move through magnetic repulsion. Then, the electric push rod 152 drives the drive motor 153 to move upward. The drive motor 153 drives the extrusion rod 156 through the drilling bit 154 to contact the bottom of the pressure guide plate through the drilling hole 21. The extrusion rod 156 is squeezed and moves inward. The drive motor 153 drives the drilling bit 154 to drill the drilling area on the pressure guide plate. After the drilling bit 154 has completed drilling the drilling area, the drilling bit 154 rotates and cuts a ring out of the pressure guide plate. After the ring does not contact the pressure guide plate, the extrusion rod 156 is not under force and moves upward with the assistance of the return spring 155 to insert into the cavity 1413 in the insertion frame 1412. Then, the extrusion rod 156 pushes the magnet 149 upward through magnetic force. Then, the ring on the drilling bit 154 slides into the inner part of the outer frame 141 through the sliding cavity 1414 and is in the receiving space formed between the two sets of isolation plates 145.

[0034] like Figure 5-8 As shown, in this embodiment, the receiving component 14 includes an outer frame 141, with a door hinged to the outer frame 141. By opening the door, the waste collected inside the outer frame 141 can be easily recycled and transferred. The bottom of the outer frame 141 is fixedly connected to the top of the first pressing plate 9. The upper and lower ends of the outer frame 141 are respectively rotatably connected to a first pulley 142 and a second pulley 143. The first pulley 142 and the second pulley 143 are connected by a belt 144. Multiple sets of isolation plates 145 are fixedly connected at equal intervals on the side wall of the belt 144. A one-way bearing is provided on the outer side wall of the outer frame 141. The outer ring of the one-way bearing is fixedly connected to the drive gear 146, and the inner ring of the one-way bearing is fixedly connected to the center of the first pulley 142. A connecting plate 147 is fixedly connected to the side wall of the outer frame 141. Among them, a connecting spring 148 is fixedly connected to the bottom of the connecting plate 147, and the bottom of the connecting spring 148 is fixedly connected to the magnet 149. The drive gear 146 meshes with the rack 1410, and the rack 1410 is fixedly connected to the magnet 149 through the connecting rod 1411. An insertion frame 1412 is fixedly connected to the side wall of the outer frame 141. The insertion frame 1412 is hollowed out to form a cavity 1413. The cavity 1413 is located in the area directly above the hole 21 on the third pressing plate 13. A sliding cavity 1414 is provided through the side wall of the outer frame 141, and the sliding cavity 1414 communicates with the cavity 1413. Among them, the upper end of the extrusion rod 156 is lower on the left and higher on the right; Among them, the size of the punched hole 21 matches that of the cavity 1413; Specifically, the two sets of drilling holes 21 and the cavity 1413 are coaxially arranged to facilitate the drilling bit 154 to pass through the drilling holes 21 and the cavity 1413 from bottom to top. Specifically, during processing, the electric push rod 152 drives the drilling bit 154 to move downwards, the magnet 149 moves downwards by the push of the connecting spring 148, the magnet 149 drives the rack 1410 to move through the connecting rod 1411, the rack 1410 meshes and drives the drive gear 146 to rotate, the drive gear 146 drives the first pulley 142 to rotate through the one-way bearing, the first pulley 142 drives the belt 144 to move, the belt 144 drives the isolation plate 145 located in the sliding cavity 1414 area to move, so that the new isolation plate 145 moves to the bottom of the sliding cavity 1414, which is convenient for storing subsequent rings, and this cycle is used to process multiple sets of pressure guide plates.

[0035] By setting up the cooperation of the driving component 15 and the receiving component 14, the present invention can punch holes in the pressure guide plate when the lower mold 2 and the upper mold are closed to make the pressure guide plate. At the same time as punching, the stamped waste ring on the pressure guide plate is automatically guided into the closed outer frame 141 for storage, which facilitates centralized processing of waste and speeds up the production efficiency of the pressure guide plate.

[0036] This invention provides a mold for manufacturing elevator guide rail pressure plates. The first pressing plate 9, the second pressing plate 11, and the third pressing plate 13 are controlled by the first driver 8, the second driver 10, and the third driver 12 respectively to perform segmented and sequential pressing, which can better control the flow and stress distribution of the plate and improve the forming quality of the pressure plate.

[0037] The present invention incorporates a drive assembly 15, in which the extrusion rod 156 within the drive assembly 15 is pressed back into the drill bit by the workpiece during drilling; after drilling is completed, the return spring 155 pushes it out, facilitating the pushing of the drilling waste ring away from the pressure guide plate; and the extrusion rod 156 pushes up the magnet 149 by magnetic force, realizing non-contact power transmission, avoiding contact between the waste on the extrusion rod 156 and the magnet 149, and facilitating the subsequent sliding of the waste into the inner frame 141.

[0038] When the drill bit 154 moves downward, the magnet 149 moves downward with the assistance of the connecting spring 148, which automatically drives the belt 144 to move one step, so that a new isolation plate 145 moves below the sliding cavity 1414, preparing to receive the next waste ring. Each time the drill bit 154 works, the collection system automatically moves forward one step, realizing the orderly arrangement and storage of waste.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
