Description

Technical Field

[0001] The invention belongs to the field of mechanical manufacturing, and in particular, is a pressing device that saves energy and increases efficiency. Background Art

[0002] Hydraulic presses are widely used in the field of industrial product manufacturing, especially for the use of various resins and adhesives for heating and pressing. The pressure of hydraulic presses is tens of tons, hundreds of tons or even thousands of tons, which has made great contributions to the upgrading of products and resource conservation. However, the products produced by hydraulic presses currently used in this field have problems such as large investment and low efficiency, especially the process requirements of some products: one, cold in and cold out, two, hot in and cold out. The curing of resin adhesives requires temperature and time. If the temperature of the product is not enough, the resin adhesive will not solidify. If the temperature does not drop to a suitable state, the product will be deformed when it comes out, and problems such as bubbling cannot be solved. If it is demolded at the specified temperature, the waiting time will be long, and the production efficiency will become low.

[0003] For the current enterprises producing heavy bamboo outdoor floor products, it costs 4-5 million yuan to invest in a hydraulic press with 10-20 layers of hot-pressed heavy bamboo indoor and outdoor floor. From loading into the press to the product out of the press, it takes 85-110 minutes to produce one mold. Among them, loading takes 5-10 minutes, pressing and curing takes 25-30 minutes, cooling takes 35-40 minutes, and demolding and discharging takes 5-10 minutes. According to 90 minutes per mold, only 16 molds can be produced in 24 hours a day. Because the products formed by the hydraulic press of resin and adhesive must be operated according to the following procedures: start-up, feeding, pressing, heating, heat preservation, curing, cooling, and out of the press. During this period, the hydraulic press always keeps the pressure standby, and the product has not cooled and fixed, and the hydraulic press cannot be separated. So this is the reason for large investment, low output and low efficiency. If you want high output, you must invest a lot of mechanical equipment.

[0004] Therefore, the present invention has the following technical problems:

[0005] 1) High investment cost. The largest investment in the production of hydraulic presses is the hydraulic main machine. For a 20-30-layer 3,000-ton press, the main machine costs 3 million yuan, and the auxiliary machine costs 2 million yuan. (The hydraulic press can move and walk. The hydraulic device moves relative to each mold assembly device through a movable connecting device. The mold assembly device is connected, clamped and separated through a movable clamping device set on the hydraulic device. The mold assembly device includes an upper mold, a lower mold and a locking device between the upper and lower molds. The pump station is set on the top instead of the side, so that the oil pump can move with the hydraulic press, and rollers are set on the 4 feet under the hydraulic press.)

[0006] 2) It takes 85-110 minutes to produce one mold from loading materials into the press to the product leaving the press. Only 16 molds can be produced in 24 hours a day, which is inefficient and has low output.

[0007] 3) For products formed by hydraulic presses with resins or adhesives, the hydraulic presses must go through the process of starting up, feeding, pressing, heating, heat preservation, curing, cooling, and exiting the press. During this period, the hydraulic presses always maintain pressure standby, the products have not cooled and formed, the hydraulic presses cannot be detached, the hydraulic presses have long standby times, and the cost of use is high.

The mechanical locking mechanisms are respectively arranged on two opposite sides of the four sides of the overall mold, and at least one is arranged on each side. The remaining two opposite sides are provided with insert blocks inserted into the sockets of the clamping device.

[0016] As a further improvement, the mechanical locking mechanism described in the present invention also includes a pin, which is inserted into the pin hole or into the gap formed between the pin hole and the lower edge of the locking plate. The part of the plug plate and / or the locking plate that contacts the pin is provided with a cylindrical stick, and the pin is fixed on the lower mold.

[0017] As a further improvement, the locking device described in the present invention also includes a bite locking mechanism, which includes a bite arm fixed on the lower mold and provided with a bite block, and a bite groove opened on the upper mold and matched with the bite block. The bite arm is connected through a hydraulic telescopic rod rotatably connected to the lower end of the bite arm, and the hydraulic telescopic rod is fixed to the lower part of the lower mold.

[0018] The present invention also discloses a method for preparing a plate using an energy-saving and efficiency-enhancing pressing device, comprising the following steps:

[0019] 1) Move the hydraulic device to the top of the corresponding mold assembly device through the concave wheel slide rail or drive the corresponding mold assembly device to move the flat plate below the mold assembly device to the bottom of the hydraulic device through the transmission mechanism;

[0020] 2) The upper mold is raised and loaded through the hydraulic opening and closing mechanism connected to the upper mold and arranged at the four corners between the upper and lower molds, and then the upper mold is lowered and closed through the hydraulic opening and closing mechanism;

[0021] 3) Align the insertion hole of the hydraulic telescopic rod of the long strip structure with the position of the insert block of the mold assembly device, and then move the long strip structure to contract by the hydraulic telescopic rod, and insert the insert block into the insertion hole;

[0022] 4) Start the hydraulic press to press down the movable plate, drive the upper mold to the required position, insert the plug plate of the upper mold into the gap between the locking plates of the lower mold, and then push the plug pin into the plug pin hole or the gap formed between the plug pin hole and the lower edge of the locking plate through the hydraulic pump;

[0023] 5) Start the hydraulic telescopic rod of the bite locking mechanism to extend, driving the mechanical arm to rotate and bite the bite groove on the upper mold;

[0024] 6) The movable plate of the hydraulic device moves up and then rises, and the hydraulic device moves to the next mold assembly device that needs to be pressed or the next pressed mold assembly device moves to the bottom of the hydraulic device to start the next round of pressing.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1) When the mobile connection device is a concave wheel set at the bottom of the hydraulic support and a slide rail set on both sides of each mold assembly device, when the concave wheel cooperates with the slide rail, multiple mold assembly devices can be installed on a straight line for pressing products, which is determined according to the production time of the products produced by themselves. The mold assembly device is the workstation for each product production, with a slide rail on each side, and the hydraulic device can move along the slide rail. There are four speed regulating motors and concave wheels at the four corners of the bottom of the hydraulic device. The concave wheels are connected to the slide rails and will not fall off or deviate when walking. The hydraulic device is provided with a movable clamping device corresponding to both sides of the slide rail. The movable clamping device includes a long strip structure with a socket and a plug block set on the mold assembly device. The plug block and the socket are matched with each other. The upper part of the long strip structure is rotatably connected to the hydraulic support above the hydraulic device through a rotating connection structure. A hydraulic telescopic rod is provided at the second connection between the long strip structure and the hydraulic support, which is used for the long strip structure to insert and leave the socket. When the hydraulic device moves, the hydraulic telescopic rod is started to open the long strip structure, and the hydraulic telescopic rod is used to close and clamp the bottom of the mold assembly device when pressing. When the hydraulic device moves to the top of the mold assembly device, it starts to work, puts down the long strip structure, holds the insert block of the lower mold of the mold assembly device and starts to press down. After the hydraulic device is pressed down to the right position, the hydraulic opening and closing mechanisms at the four corners of the mold assembly device are also pressed down to the bottom at the same time, and the mechanical hydraulic locking device is locked in place. The hydraulic device opens the long strip structure through the hydraulic telescopic rod, starts the speed regulating motor and moves to the next mold assembly device to repeat the same work.

[0027] 2) When the mobile connection device is a flat plate provided at the bottom of each mold assembly device for driving each mold assembly device to move to the bottom of the movable flat plate of the hydraulic device, the hydraulic press is installed in a fixed position, multiple mold assembly devices are connected as one, and a slide rail is installed under the mold assembly device. After the mold assembly device and the mold assembly device are connected as one, a concave wheel is installed on the bottom slide rail of the mold assembly device. The motor determines the number of wheels to be installed according to the number and length of the mold assembly devices. There is a flat plate of similar size to the mold assembly device at the bottom of the hydraulic press. When the mold assembly device containing the raw material moves to the fixed hydraulic press position, the hydraulic pressure at the bottom of the hydraulic press raises the flat plate to the bottom of the corresponding mold assembly device and matches the bottom of the mold assembly device. Then the hydraulic device is pressed down and locked after it is in place. The hydraulic device is depressurized, the bottom flat plate returns to its original position, the mold assembly device moves out of the hydraulic device, and the second mold assembly device follows, and the operation of the first mold assembly device is repeated.

[0028] 3) The present invention uses the design of a mobile connecting device to make full use of a hydraulic press to simultaneously press many mold components in the shortest time, thereby improving production efficiency and increasing output.

[0029] 4) It overcomes the problems in the prior art that the hydraulic device always maintains pressure standby, the product has not cooled and shaped, the hydraulic device cannot be disengaged, the hydraulic press has a long standby time, and the cost of use is high. Through the design of the locking device, the hydraulic device can be disengaged, and the locking device can be locked to keep the product under pressure to cool and shape. The hydraulic device can be used to hydraulically press other mold components without being idle and wasting time, thereby reducing the cost of use.

[0030] 5) It is not necessary to invest in too many hydraulic devices. For a 3,000-ton press with 20 to 30 layers, the main hydraulic press costs 3 million yuan, and the auxiliary equipment costs 2 million yuan. The overall design of the device of the present invention avoids the cost waste of purchasing multiple hydraulic devices.

[0031] 6) The oil pump main station is set on the top of the hydraulic device and can be moved freely along with the hydraulic support, replacing the solution in the prior art that the oil pump main station is placed in a fixed position such as a fixed ground. This is to allow the pressing device to realize the oil pump hydraulics while being movable, and will not affect the pressing of products of other mold component devices because the oil pump main station is in a fixed state and cannot be moved to the position of the other mold component devices.

[0032] 7) Through the design of the clamping device, the mold assembly device can be clamped tightly. The hydraulic device presses down the upper mold with great pressure. Only by clamping can the pressing be stable. The socket of the long strip structure is docked with the plug block on the mold assembly device and clamped and fixed. When the pressing is completed, the long strip structure is supported by the hydraulic telescopic rod connected to the long strip structure and fixed on the hydraulic support, and the long strip structure is opened away from the plug block on the mold assembly device. The hydraulic press can move to another mold assembly device for a new round of pressing.

[0033] 8) The mechanical locking mechanism is also provided with a cylindrical rod, which allows the pin to enter the pin hole more smoothly and can roll in to reduce friction.

[0034] 9) Through the design of the double locking structure of the mechanical locking mechanism and / or the bite locking mechanism, the mechanical locking mechanism includes a pair of locking plates, a plug plate inserted into the gap between the pair of locking plates, and a plug pin inserted into the plug pin hole set on the plug plate; the bite locking mechanism includes a bite arm with a bite block at one end, and a bite groove matched with the bite block. When the hydraulic device is disengaged, the mold assembly device can continue to maintain pressure and cool and shape. Free up time for the hydraulic device to act on other mold assembly devices. Firm locking and guaranteed pressure help the hydraulic press to maintain the required pressure when preparing products and ensure product quality.

[0035] 10) A cylindrical rod in contact with the latch is provided on the lower edge of the latch hole and the lower edge of a pair of locking plates, or on the upper and lower edges of the latch hole. The latch is fixed on the lower mold. The latch includes a triangular bevel that contacts the cylindrical rod and slides back and forth relative to the cylindrical rod. This is to allow the latch to enter the latch hole more smoothly and roll in to reduce friction. The cylindrical rod and the latch are made of specially treated materials, wear-resistant, high-strength bearing steel.

[0036] 11) A set of mechanical locking mechanisms including a pair of locking plates, a plug plate and a plug pin are designed and arranged on two opposite sides of the four sides of the overall mold, and at least one is arranged on each side to ensure a certain number to ensure stable locking and smooth pressing.

[0037] 12) A movable long strip structure is provided on the hydraulic support of the hydraulic device, and the movable long strip structure includes a long strip structure with a clamping hole and a clamping block arranged on the mold assembly device, the clamping block and the clamping hole are matched with each other, and the upper part of the long strip structure is rotatably connected to the hydraulic support above the hydraulic device through a rotating connection structure, and a hydraulic telescopic rod is provided at the second connection between the long strip structure and the hydraulic support for inserting the long strip structure into and leaving the clamping hole. When the hydraulic device is moving, the hydraulic telescopic rod is started to open the long strip structure, and when pressing, the hydraulic telescopic rod is used to close and clamp the bottom of the mold assembly device.

[0038] 13) Through the design of the long strip structure, the mold assembly device can be tightly held. The hydraulic device presses down the upper mold with great pressure. Only by holding it tightly can the pressing be stable. The holding hole of the long strip structure is docked with the holding block on the mold assembly device to hold it tightly and fix it. When the pressing is completed, the long strip structure is supported by the hydraulic telescopic rod connected to the long strip structure and fixed on the hydraulic support. The long strip structure is opened away from the holding block on the mold assembly device, and the hydraulic press can be moved to another mold assembly device for a new round of pressing.

[0039] 14) The long strip structure is designed to have an inverted U-shaped cross-section, and a long strip through hole is formed between the two side walls of the inverted U-shape, which has lower cost and simple structure. At the same time, the hollowing out in the middle reduces the weight of the long strip structure, making it convenient for the long strip structure to rotate around the connecting fixed plate as needed to achieve clamping and separation. The hydraulic telescopic rod set between the long strip structure and the hydraulic support is used to control the clamping block to insert and leave the clamping hole. The hydraulic telescopic rod is connected to the background master controller, and the angle of the long strip structure is controlled to a suitable position through the master controller.

[0040] 15) By designing the clamping block to be in clamping contact with the lower wall and the inner wall of the side wall of the inverted U-shaped long strip structure, a firm and stable clamping fixation between the clamping block and the clamping hole can be ensured.

After the mold assembly device 3 is connected as one, a concave wheel 13 is installed on the slide rail 14 at the bottom of the mold assembly device 3. The motor determines how many wheels are installed according to the number and length of the mold assembly devices 3. There is a plate of similar size to the mold assembly device 3 at the bottom of the hydraulic press. When the mold assembly device 3 loaded with raw materials moves to the fixed hydraulic press position, the hydraulic pressure at the bottom of the hydraulic press raises the plate to the bottom of the corresponding mold assembly device 3 and matches the bottom of the mold assembly device 3. Then the hydraulic device presses down and locks after it is in place. The hydraulic device releases pressure, the bottom plate returns to its original position, the mold assembly device 3 moves out of the hydraulic device, and the second mold assembly device 3 follows, repeating the work of the first mold assembly device 3.

[0073] Specific implementation cases:

[0074] The present invention discloses an energy-saving and efficiency-enhancing pressing device, wherein a plurality of loading mold assembly devices 3 are installed in a straight line (the number of mold assembly devices 3 is determined according to the time of one cycle of loading pressing, heating, curing, cooling, and demoulding), and each mold assembly device 3 has an upper mold and a lower mold, and is surrounded by a lifting cylinder 5 and a side locking device. The length and width of the mold assembly device 3 are determined according to the size of the product to be produced, and the height (that is, the number of layers pressed at one time) is also determined according to the product to be produced.

[0075] Step 1: Use the hydraulic cylinders 5 around the mold assembly device 3 to raise the upper mold until it can be loaded;

[0076] Step 2: Load the raw materials for the product between the upper and lower molds. If multiple layers are required, load the required number of layers. You can also push the raw materials in at once after loading them outside.

[0077] Step 3: After the materials are loaded, the surrounding hydraulic opening and closing mechanisms 4, i.e., the hydraulic cylinders 5, are pressed down.

[0078] The hydraulic cylinder 5 of the mold assembly device 3 cannot press into place because of the low pressure. It needs a mobile host to operate. The host generally has a pressure of 1000 tons to 3000 tons, and rails are installed on both sides of the linear mold assembly device 3. The main press has four feet at the four corners, and motors are installed on the corners. The motor drives the concave wheels 13 on the press feet that match the guide rails and are equipped with a speed regulator. After the third step of the first mold assembly device 3 is completed, the host moves to the first mold assembly device 3, puts down the clamping device 23 and tightens the lower mold of the mold assembly device 3, and then starts to press down. It is pressed down to the required position and locked by a mechanical lock. After locking, the main press can go to the second mold assembly device 3 to perform the same process.

[0079] When the hydraulic device is pressing the first mold assembly device 3, the second mold assembly device 3 requires the raw materials to be installed, and the surrounding hydraulic cylinders 5 have been pressed down. After the main press machine has completed the pressing of the first mold assembly device 3, it will move to the second mold assembly device 3 for pressing. When pressing the second mold assembly device 3, the raw materials of the third mold assembly device 3 have been installed, and the hydraulic cylinders 5 of the mold assembly device 3 are pressed down. In this way, the hydraulic device is operated in a cycle. In addition to moving, it is also a pressing operation, and there is no spare time to wait. In addition, for the products currently in production, which use resins, adhesives, and solidification, each hydraulic press cannot move. It is fixed on the mold assembly device 3 for loading, heating, solidification, heat preservation, and pressure relief, and it plays the role of a locking device. Therefore, it takes 85-110 minutes to produce a mold of heavy bamboo outdoor flooring, and the walking hydraulic device has a walking speed of 20 cm to 100 cm per second. The distance between the first mold assembly device 3 and the second mold assembly device 3 is 120 cm, and the width of the mold assembly device 3 is 180 cm, totaling 300 cm. The main machine walks at 50 cm per second. It takes 6 seconds to travel from the first mold assembly device 3 to the second mold assembly device 3, plus 4 seconds from start to stop, a total of 10 seconds. After pressing all the mold assembly devices 3, it has to return to the first mold assembly device 3, so each mold assembly device 3 takes 10 seconds, and the total hydraulic press round-trip time is 20 seconds. The time for the main press to press the product from the mold assembly device 3 into place and lock it is 20 to 30 seconds. In this way, the time for the hydraulic press of each mold assembly device 3 to travel back and forth is 20 seconds, and the pressing time including the locking time is 30 seconds, and the two add up to 50 seconds. 50 seconds to press one mold and 90 minutes to press one mold for outdoor heavy bamboo, the efficiency is increased by more than 100 times, and the investment amount will inevitably decrease a lot.
