Description

[0002] In the elevator manufacturing industry, counterweights are the core components of the balancing system, and their production process directly affects the safety and stability of elevator operation. Traditionally, counterweights are produced by filling the shell with composite materials, requiring the compressive strength to meet certain requirements. Counterweights are generally pressed by a press, but the existing presses used for counterweight production have the following problems: (1) the counterweights are difficult to transport after pressing; (2) it is impossible to achieve quantitative feeding of raw materials; and (3) the raw materials are not leveled, resulting in unqualified counterweights after pressing. Summary of the Invention

[0003] The purpose of this invention is to provide a press for producing counterweights with a quantitative feeding function, so as to solve the problems mentioned in the prior art.

The two ends of the rotating rod are rotatably mounted on the two sets of receiving plates. One end of the rotating rod passes through one set of receiving plates and is connected to the output end of the drive motor. The drive motor is mounted on one set of receiving plates. Fixed cylinders and feeding cylinders are respectively installed at both ends and the middle part of the rotating rod. A conveying sleeve is provided on the rotating rod located inside the feeding cylinder. Several partitions are arranged in sequence on the outside of the conveying sleeve. A cross plate is arranged between two adjacent partitions. The cross plate divides the feeding cylinder between two adjacent sets of partitions into four conveying chambers. Four sets of piezoelectric ceramic plates are arranged in the middle of the cross plate. The piezoelectric ceramic plates are electrically connected to the control system. The cross-section of the cross plate is cross-shaped, the cross plate is made of metal, and a coil is embedded in the feeding cylinder. The two ends of the coil are electrically connected to the control system.

[0006] The feeding cylinder is mounted on two sets of fixed plates. Several inlets and outlets are provided on the upper and lower sides of the feeding cylinder, respectively. The inlets and outlets are located between two adjacent sets of partitions. The inlets are connected to the feeding system through pipes, and a solenoid valve is installed inside the inlets.

[0007] The two sets of fixed cylinders are respectively installed on the two sets of receiving plates. A sliding ring is slidably installed on the outside of the fixed cylinder. An electromagnetic spring is connected between the sliding ring and the fixed cylinder. The two ends of the electromagnetic spring are electrically connected to the control system. The two sets of clamping frames are symmetrically arranged. The top of the clamping frames is provided with two sets of connecting parts. Each set of connecting parts is provided with a sliding groove. A sliding shaft is provided on the outer side of the sliding ring. Each of the two sets of fixing plates is provided with a slide rail on the opposite side. The sliding shaft is slidably connected to the slide rail. The sliding groove is slidably connected to the sliding shaft. A displacement sensor is provided in the slide rail.

[0008] A rotating component is provided on the clamping frame between the two sets of connecting parts, and the rotating component is rotatably connected to the bottom of the fixed cylinder.

[0009] The clamping frame has several drive rollers on one side and a clamping frame on the other side. The clamping band is sleeved on the drive rollers and is made of several steel strips spliced ​​together. The drive rollers are electrically connected to the control system. The clamping band has several clamping members with an "S" shaped cross-section and an impact post in the middle.

[0010] The vibrating plate is slidably connected to the clamping frame, and a vibration spring is connected between the clamping frame and the vibrating plate. A vibration column is provided on the vibrating plate, and the vibration column abuts against the impact column.

[0011] The high-pressure oil pump is mounted on the machine casing. The inlet of the high-pressure oil pump is connected to the oil tank through a pipe. The outlet of the high-pressure oil pump is connected to the top of the oil injection cylinder. Both the oil injection cylinder and the oil tank are located on the machine casing. The bottom of the oil injection cylinder is connected to the oil tank through a pipe. A sliding column is provided on the upper side of the sliding seat, and the sliding column is slidably connected to the oil injection cylinder.

[0012] The template is provided in four sets, and each of the four sets of templates is connected to the telescopic rod of the positioning cylinder, which is installed on the machine housing.

[0013] The high-pressure oil pump and the oil injection cylinder are both mounted on the machine housing, and the sliding seat is slidably mounted on the machine housing; The casing is equipped with an escalator and a control box, and the control system is located inside the control box.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The material is diverted, conveyed, and clamped using clamping belts, resulting in a more compact structure. The material is sequentially dropped into different positions within the mold cavity by two sets of clamping belts, ensuring even distribution and preventing localized accumulation, thus improving material uniformity. The control system uses drive rollers within the two clamping frames to move the two sets of clamping belts. These belts then convey the clamped counterweight forward, positioning it above the unloading line and allowing it to be transported via the line. This more compact structure improves counterweight production efficiency.

[0015] 2. Quantitative feeding of raw materials avoids excessive or insufficient material, which could adversely affect the production of counterweights. The control system opens the solenoid valves in several feed ports and conveys the raw materials to these ports via the feeding system. The raw materials enter several conveying chambers through these ports, accumulating on piezoelectric ceramic plates within the conveying chambers. The piezoelectric ceramic plates in the conveying chambers convert the pressure deformation of the raw materials into electrical signals, and the control system calculates the mass of the raw materials to achieve quantitative feeding, thus avoiding excessive or insufficient material that could adversely affect the production of counterweights.

[0016] 3. Raw material leveling treatment to improve the production quality of counterweights. When the impact column and the vibrating column approach each other, the impact column pushes the vibrating plate away from the clamping belt through the vibrating column, and the vibrating plate stretches the vibrating spring at the same time; when the impact column and the vibrating column move away from each other, the vibrating spring is released, and the vibrating spring pulls the vibrating plate towards the clamping belt; as the clamping belt continues to move, the vibrating plate continues to vibrate up and down, leveling the raw material in the mold cavity, so as to press the raw material in the mold cavity into counterweights, avoiding uneven distribution of raw material in the mold cavity, avoiding gaps or air holes in the formed counterweights, and improving the production quality of counterweights.

[0025] The high-pressure oil pump 111 is installed on the housing 11. The inlet of the high-pressure oil pump 111 is connected to the oil tank through a pipe. The outlet of the high-pressure oil pump 111 is connected to the top of the oil injection cylinder 112. Both the oil injection cylinder 112 and the oil tank are located on the housing 11. The bottom of the oil injection cylinder 112 is connected to the oil tank through a pipe. A sliding column is provided on the upper side of the sliding seat 2. The sliding column is slidably connected to the oil injection cylinder 112.

[0026] Working principle: Press the start button on the control box 1 to start the press. The control system drives the four sets of templates 4 to move forward through the four sets of positioning cylinders 41, so that the four sets of templates 4 move closer to each other and form a mold cavity with the shape of a counterweight, so that the raw material can be pressed into a counterweight through the mold cavity.

[0027] After the four sets of templates 4 are moved into place, the displacement sensor in the positioning cylinder 41 feeds the data back to the control system. The control system energizes the two sets of electromagnetic springs 242. After being energized, the two sets of electromagnetic springs 242 gradually contract. The two sets of electromagnetic springs 242 pull the two sets of sliding rings 241 to move forward. The two sets of sliding rings 241 drive the two sets of sliding shafts 243 to slide in the slide rail. The two sets of sliding shafts 243 also drive the two sets of connecting parts 301 to rotate a certain angle through the slide groove. The two sets of connecting parts 301 drive the two sets of clamping frames 3 to rotate a certain angle. The two sets of clamping frames 3 drive the two sets of clamping belts 31 to rotate a certain angle so that the lower ends of the two sets of clamping belts 31 are close to each other. At this time, the two sets of clamping belts 31 change from the original vertical state to the inclined state to facilitate the conveying and diversion of raw materials.

[0028] As the lower ends of the two sets of clamping frames 3 approach each other, the control system opens the solenoid valves in several feed ports 256 and conveys the raw material to the feed ports 256 through the feeding system. The raw material enters several conveying chambers through the feed ports 256 respectively. The raw material accumulates on the piezoelectric ceramic plate 254 in the conveying chamber. The piezoelectric ceramic plate 254 in the conveying chamber converts the pressure deformation of the raw material into an electric charge signal, and calculates the mass of the raw material through the control system to achieve quantitative feeding of the raw material. When the raw material quality data detected by the piezoelectric ceramic plates 254 in several conveying chambers meets the set requirements, the control system closes the solenoid valves in several feed ports 256, preventing the raw material from continuing to enter the several conveying chambers. At this time, the control system drives the rotating rod 22 to rotate by a certain angle through the drive motor 23. The rotating rod 22 drives the conveying sleeve 251, partition 252, cross plate 253 and piezoelectric ceramic plate 254 to rotate by a certain angle, so that the raw material in several conveying chambers rotates by a certain angle and is discharged from several discharge ports 257 in sequence. The raw material is discharged from several discharge ports 257 onto the clamping belts 31 of the two sets of clamping frames 3. The raw material is diverted by the clamping parts 312 on the two sets of clamping belts 31. As the two sets of clamping belts 31 gradually rotate by a certain angle, the raw material falls down to different positions in the mold cavity in sequence through the two sets of clamping belts 31, so that the raw material is evenly distributed in the mold cavity, avoiding local accumulation of raw material in the mold cavity and improving the uniformity of raw material in the mold cavity.

[0029] When the raw material enters the several conveying chambers through several feed ports 256, the feeding system feeds back the flow data of the raw material to the control system. The control system energizes the coil 255, which generates an alternating magnetic field, causing the cross plate 253 to cut the magnetic field lines and generate heat. The cross plate 253 heats the raw material so that the heated raw material enters the mold cavity.

[0030] When the raw material is fully inside the mold cavity, the feeding system feeds back the flow rate data of the raw material to the control system. The control system increases the current supplied to the two sets of electromagnetic springs 242, causing the two sets of electromagnetic springs 242 to pull the two sets of sliding rings 241 to continue moving. The sliding rings 241 drive the sliding shaft 243 to slide in the slide rail. The sliding shaft 243 also drives the connecting piece 301 to rotate a certain angle through the slide groove. The connecting piece 301 drives the clamping frame 3 to rotate a certain angle. The two sets of clamping frames 3 drive the two sets of clamping belts 31 to rotate a certain angle, so that the two sets of clamping frames 3 and the two sets of clamping belts 31 are in a horizontal state. At this time, the vibration plates 32 on the two sets of clamping frames 3 are facing the mold cavity, and the size of the two sets of vibration plates 32 is the same as the internal size of the mold cavity.

[0031] When the two sets of vibrating plates 32 are directly above the mold cavity, the control system delivers hydraulic oil from the oil tank to the oil injection cylinder 112 through the high-pressure oil pump 111. The hydraulic oil pushes the sliding column to move downward, the sliding column drives the sliding seat 2 to move downward, the sliding seat 2 drives the bracket 21 to move downward, the bracket 21 drives the support column, the two sets of fixing plates 211 and the two sets of receiving plates 212 to move downward, the two sets of receiving plates 212 and the two sets of fixing plates 211 drive the two sets of clamping frames 3 to move downward, and the two sets of clamping frames 3 respectively drive the two sets of vibrating plates 32 to move downward, and make the two sets of vibrating plates 32 enter the mold cavity. When the two sets of vibrating plates 32 come into contact with the raw material in the mold cavity, the high-pressure oil pump 111 feeds back the hydraulic oil pressure data to the control system. The control system drives the two sets of clamping belts 31 to move through the drive rollers 311 on the two sets of clamping frames 3. The clamping parts 312 and impact columns 313 on the two sets of clamping belts 31 move accordingly. When the impact column 313 and the vibrating column 321 approach each other, the impact column 313 pushes the vibrating plate 32 away from the clamping belt 31 through the vibrating column 321. At the same time, the vibrating plate 32 stretches the vibration spring. When the impact column 313 and the vibrating column 321 move away from each other, the vibration spring is released and pulls the vibrating plate 32 towards the clamping belt 31. With the continuous movement of the clamping belt 31, the vibrating plate 32 continuously vibrates up and down, leveling the raw material in the mold cavity so that the raw material in the mold cavity can be pressed into a counterweight, avoiding uneven distribution of the raw material in the mold cavity and avoiding gaps or air holes in the formed counterweight.

[0032] When the raw material in the mold cavity vibrates for a set time, the encoder in the drive roller 311 feeds the data back to the control system. The control system continues to deliver hydraulic oil to the oil injection cylinder 112 through the high-pressure oil pump 111, so that the sliding seat 2, the bracket 21, the two sets of receiving plates 212, the two sets of fixing plates 211, the two sets of clamping frames 3 and the two sets of vibrating plates 32 continue to move downward. The two sets of vibrating plates 32 press down on the raw material in the mold cavity and press the raw material into a counterweight.

[0033] After the raw materials are pressed into counterweights, the control system uses the high-pressure oil pump 111 to draw hydraulic oil out of the oil injection cylinder 112, so that the two sets of vibrating plates 32 move upward to the set position. At this time, the control system de-energizes the electromagnetic spring 242. The electromagnetic spring 242 gradually lengthens under its own elastic force. The electromagnetic spring 242 pushes the sliding ring 241 to move in the opposite direction. The sliding ring 241 drives the sliding shaft 243 to slide in the opposite direction in the slide rail. The sliding shaft 243 also drives the connecting piece 301 to rotate in the opposite direction by a certain angle through the slide groove. The connecting piece 301 drives the clamping frame 3 to rotate in the opposite direction by a certain angle. The two sets of clamping frames 3 respectively drive the two sets of clamping belts 31 to rotate in the opposite direction by a certain angle, so that the two sets of clamping belts 31 change from the original horizontal state to the vertical state. At this time, the distance between the two sets of clamping belts 31 is greater than the width of the counterweight.

[0034] When the distance between the two sets of clamping belts 31 is greater than the width of the counterweight, the control system drives the four sets of templates 4 to move in the opposite direction through the four sets of positioning cylinders 41, so that the four sets of templates 4 are away from the counterweight, so as to clamp the counterweight.

[0035] When the four sets of templates 4 move away from the counterweight, the control system delivers hydraulic oil to the oil injection cylinder 112 via the high-pressure oil pump 111, causing the two sets of clamping frames 3 and clamping belts 31 to move downwards, positioning the two sets of clamping belts 31 on both sides of the counterweight. When the two sets of clamping belts 31 are positioned on both sides of the counterweight, the control system energizes the electromagnetic spring 242, causing the lower ends of the two sets of clamping frames 3 to move closer together again. The two sets of clamping frames 3 respectively drive the two sets of clamping belts 31 from their original vertical state to an inclined state, and the clamping parts 312 on the two sets of clamping belts 31 clamp the counterweight. After the counterweight is clamped by the clamping parts 312 on the two sets of clamping belts 31, the displacement sensor in the slide rail feeds data back to the control system, and the control system uses the high-pressure oil pump 111 to... Hydraulic oil in the oil injection cylinder 112 is drawn outward to move the two sets of clamping frames 3 and clamping belts 31 upward. The two sets of clamping belts 31 drive the counterweight to move upward. Then, the control system drives the two sets of clamping belts 31 to move through the drive rollers 311 in the two sets of clamping frames 3. The two sets of clamping belts 31 transport the clamped counterweight forward so that the counterweight is above the unloading line. Finally, the control system de-energizes the electromagnetic spring 242 so that the lower ends of the two sets of clamping frames 3 move away from each other. The two sets of clamping frames 3 drive the two sets of clamping belts 31 to change from the original inclined state to the vertical state. The distance between the two sets of clamping belts 31 is greater than the width of the counterweight. The counterweight will fall downward onto the unloading line and be transported through the unloading line.
