Abstract
Description
Technical Field
[0001] This invention relates to a barrel hoop pressing machine and method, belonging to the field of barrel making machinery technology. Background Technology
[0002] Wooden barrels, especially oak barrels used for aging wine and brandy, are typically made by joining multiple curved wooden strips (barrel planks) together at the edges to form the barrel body, which is then secured at both ends with hoops. The hoops provide a continuous radial preload to the barrel body, resisting the static pressure of the liquid and the shrinkage and expansion of the wood during aging, preventing the barrel from cracking or leaking. Early barrel hooping relied primarily on manual labor using tools such as hammers and crowbars. This method was labor-intensive, inefficient, and the quality of the hooping depended heavily on the worker's experience and skill, easily leading to uneven force distribution, resulting in misaligned hoops, damaged barrel planks, or incomplete seals.
[0003] To improve this situation, some simple mechanical or hydraulic clamping devices have appeared on the market. These devices typically apply force to the clamps using a single pushing, clamping, or tightening method. However, the force application point of such devices is singular or asymmetrical, causing the barrel to easily deflect during the tightening process. This prevents the clamps from contracting evenly around the barrel, affecting the roundness and tightness of the clamped rings, and may also lead to problems such as difficulty in pre-fitting the clamps, misalignment, or slippage.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Summary of the Invention
[0005] The purpose of this invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.
[0006] The technical solution provided by this invention is as follows: A barrel clamp pressing machine, comprising: The frame includes a bottom beam, a platform located in the middle of the bottom beam, an upper frame beam, and four guide columns supporting the bottom beam and the upper frame beam. A movable pressure beam is provided, with its four corners slidably connected to the four guide columns. The movable pressure beam has a central hole in its middle. A flared clamping cylinder is installed at the central hole; The device includes a movable pressure beam drive mechanism, comprising four lifting hydraulic cylinders, the cylinder bodies of which are all mounted on the upper frame beam, and the piston rods of which pass through the upper frame beam and are connected to the movable pressure beam.
[0007] Compared with the prior art, the technical solution provided by this invention has the following beneficial effects: The barrel hoop pressing machine provided by this invention, by setting four guide columns that are slidably connected to the four corners of the movable pressure beam, and cooperating with four lifting hydraulic cylinders for synchronous drive, can still maintain a stable and vertical downward movement when subjected to the eccentric load moment or the radial resistance of the barrel body during the barrel hoop pressing process. At the same time, the trumpet-shaped clamping cylinder set at the central hole of the movable pressure beam provides continuous conical surface guidance for the barrel hoop, so that the barrel hoop remains aligned with the axis of the barrel body throughout the pressing process. When the movable pressure beam drives the trumpet-shaped clamping cylinder downward, the inner wall of the clamping cylinder applies a radial closing force to the end of the barrel body, causing the barrel plate to move inward and the diameter of the barrel end to gradually decrease. At this time, the barrel hoop is placed at the barrel end. Since the diameter of the barrel end is smaller than the inner diameter of the barrel hoop, the barrel hoop can be easily fitted and naturally fall on the upper part of the inclined surface of the clamping cylinder without hammering or forced flaring, solving the problems of difficult barrel hoop pre-fitting, skewness, and slippage in traditional processes.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, the horn-shaped clamping cylinder is composed of two opposing semi-conical cylinders. The two semi-conical cylinders are respectively mounted on the movable pressure beam via telescopic hydraulic cylinders. The cylinder body of the telescopic hydraulic cylinder is mounted on the movable pressure beam, and the piston rod of the telescopic hydraulic cylinder is connected to the corresponding semi-conical cylinder.
[0010] This invention uses two semi-conical cylinders that fit together. Before pressing, the two semi-conical cylinders are in an open state, and the barrel can be placed between the two semi-conical cylinders. After the two semi-conical cylinders are closed, a complete trumpet-shaped guide surface is formed on the outer periphery of the barrel end. After pressing is completed, the semi-conical cylinders are opened again, and the barrel can be moved out without obstruction.
[0011] Furthermore, it also includes a conveying mechanism, which includes two guide rails and a transmission chain. The platform is slidably mounted on the guide rails and moves back and forth relative to the frame under the drive of the transmission chain.
[0012] Furthermore, the movable pressure beam has at least three claws around its central hole, which are used to hold the barrel hoop and move down synchronously with the movable pressure beam.
[0013] Furthermore, the position of the claw is adjustable and mounted on the movable pressure beam.
[0014] Furthermore, the claw is equipped with a permanent magnet.
[0015] Furthermore, the permanent magnet is a neodymium iron boron magnet.
[0016] Furthermore, at least the upper half of the wall of the horn-shaped clamping cylinder is embedded with a plurality of ball bearings.
[0017] A method for pressing barrel hoops, utilizing the aforementioned barrel hoop pressing machine, includes: S1. Control the telescopic hydraulic cylinder to drive the two semi-conical cylinders to the open state, place the barrel on the platform and make the upper end of the barrel face the horn-shaped buckling cylinder. S2. Control the four lifting hydraulic cylinders to drive the movable pressure beam downwards, so that the height of the uppermost end of the trumpet-shaped pressing cylinder is lower than the height of the uppermost end of the barrel. Then control the telescopic hydraulic cylinder to drive the two semi-conical cylinders to move towards each other until they are in a closed state. S3. Place the barrel hoop on the clamp; S4. Control the four lifting hydraulic cylinders to drive the movable pressure beam to continue to descend, and the trumpet-shaped clamping cylinder moves down accordingly and applies a uniform radial contraction force to the barrel, so that the diameter of the upper end of the barrel gradually decreases. S5. When the diameter of the upper end of the barrel is reduced to less than the inner diameter of the barrel hoop, the claw pulls the barrel hoop down to the outer edge of the upper end of the barrel. S6. Control the telescopic hydraulic cylinder to drive the two semi-conical cylinders to move in the opposite direction to the open state, thereby releasing the radial constraint on the end of the barrel. S7. Drive the movable pressure beam to move upward and reset, causing the claws and horn-shaped clamping cylinder to move away from the end of the barrel, and move the barrel with the barrel hoop installed out of the platform.
[0018] Compared with the prior art, the technical solution provided by the present invention has the following advantages: the barrel hoop pressing method provided by the present invention has a continuous process and is easy to operate. It is applicable to barrel hoop pressing of barrels of different specifications and can complete the placement and pressing of multiple barrel hoops in a continuous downward movement.

[0023] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.
[0024] like Figure 1 - Figure 3As shown, a barrel clamping machine includes: a frame 100, a horn-shaped clamping cylinder, and a driving device for a movable clamping beam 103. The frame 100 includes a bottom beam 101, a platform located in the middle of the bottom beam 101, an upper frame beam 102, and four guide columns 104 supported between the bottom beam 101 and the upper frame beam 102. The movable clamping beam 103 has four corners slidably connected to the four guide columns 104, and a central hole in the middle of the movable clamping beam 103. The horn-shaped clamping cylinder is installed at the central hole. The driving device for the movable clamping beam 103 includes four lifting hydraulic cylinders 300, the cylinder bodies of which are all located on the upper frame beam 102. The piston rods of the lifting hydraulic cylinders 300 pass through the upper frame beam 102 and are connected to the movable clamping beam 103.
[0025] The horn-shaped clamping cylinder is composed of two opposing semi-conical cylinders 200. Each of the two semi-conical cylinders 200 is mounted on the movable pressure beam 103 via a telescopic hydraulic cylinder 900. The cylinder body of the telescopic hydraulic cylinder 900 is mounted on the movable pressure beam 103, and the piston rod of the telescopic hydraulic cylinder 900 is connected to the corresponding semi-conical cylinder 200. This invention uses two opposing semi-conical cylinders 200. Before pressing, the two semi-conical cylinders 200 are in an open state, allowing the barrel 600 to be placed between them. After the two semi-conical cylinders 200 are closed, a complete horn-shaped guide surface is formed around the end of the barrel 600. After pressing, the semi-conical cylinders 200 are reopened, allowing the barrel 600 to be moved out without obstruction.
[0026] like Figure 4 and Figure 5 As shown, the present invention also includes a conveying mechanism 400, which includes two guide rails and a transmission chain. The platform is slidably disposed on the guide rails and moves back and forth relative to the frame 100 under the drive of the transmission chain.
[0027] like Figure 6 - Figure 8 As shown, the movable pressure beam 103 has at least three claws 800 around its central hole. The claws 800 are used to hold the barrel hoop 700 and move downwards synchronously with the movable pressure beam 103. The three claws 800 define a plane, which can keep the barrel hoop 700 in a horizontal state.
[0028] The adjustable clamp 800 is mounted on the movable pressure beam 103. By adjusting the position of the clamp 800, it can accommodate barrels 600 and barrel hoops 700 of different diameters, improving the versatility and flexibility of the equipment. The position adjustment structure of the clamp 800 can adopt screw drive, slide rail guide, or other forms to ensure a smooth and reliable adjustment process, and to ensure that it can be firmly locked after adjustment to prevent displacement during the pressing process.
[0029] The claw 800 is equipped with a permanent magnet, which is a neodymium iron boron magnet. When the barrel hoop 700 is placed on the claw 800, the attraction of the permanent magnet can adjust the barrel hoop 700 to a horizontal state, preventing the barrel hoop 700 from shifting or shaking during the downward movement of the movable pressure beam 103, thus ensuring the accuracy and stability of the pressing process.
[0030] At least the upper half of the wall of the flared pressing cylinder is provided with a plurality of ball bearings 500. During the pressing process, the ball bearings 500 can reduce the friction between the barrel 600 and the flared pressing cylinder, so that the end of the barrel 600 can move inward more smoothly when subjected to radial closing force, and avoid scratches or damage to the surface of the barrel 600 due to excessive friction.
[0031] The barrel 600 to be clamped is open at both ends and has a hollow internal structure. One end has been clamped with a metal hoop, while the other end is in a free expansion state with a larger diameter before the barrel hoop 700 is installed. The method for clamping the other end using the barrel 600 and barrel hoop 700 press-fitting machine of the present invention is as follows: S1. Control the telescopic hydraulic cylinder 900 to drive the two semi-conical cylinders 200 to the open state, place the barrel 600 on the platform and make the upper end of the barrel 600 face the horn-shaped clamping cylinder. The two semi-conical cylinders 200 are in the open state, and the movable pressure beam 103 is located in the upper position near the upper frame beam 102; the barrel 600 to be pressed and loaded with barrel hoops 700 is transported to the center of the platform by the conveying mechanism 400 or manually, and the upper opening of the barrel 600 is oriented towards the direction of the flared clamping cylinder; the position of the barrel 600 is adjusted so that the axis of the barrel 600 is basically aligned with the axis of the central hole of the movable pressure beam 103.
[0032] S2. Control the four lifting hydraulic cylinders 300 to drive the movable pressure beam 103 downward, so that the height of the uppermost end of the trumpet-shaped pressing cylinder is lower than the height of the uppermost end of the wine barrel 600. Then control the telescopic hydraulic cylinder 900 to drive the two semi-conical cylinders 200 to move towards each other to the matching state. Adjust the height of the movable pressure beam 103 so that the height of the uppermost end of the trumpet-shaped clamping cylinder is lower than the height of the uppermost end of the barrel 600; control the extension of the telescopic hydraulic cylinder 900 to drive the two semi-conical cylinders 200 to move towards each other until the two semi-conical cylinders 200 are aligned; after alignment, the inner wall of the trumpet-shaped clamping cylinder contacts the outer circumferential surface of the end of the barrel 600, and the upper end of the barrel 600 is radially constrained by the inner wall of the trumpet-shaped clamping cylinder.
[0033] S3, such as Figure 6 As shown, place the barrel hoop 700 on the jaw 800; More specifically, the claw 800 is slidably mounted on the movable pressure beam 103. According to the specifications of the barrel hoop 700 to be pressed, the position of the claw 800 around the central hole of the movable pressure beam 103 is adjusted by the slide groove or slide rail. The barrel hoop 700 is placed on the claw 800, so that the barrel hoop 700 is held by the claw 800. The permanent magnet on the claw 800 attracts the outer edge of the barrel hoop 700 to keep the barrel hoop 700 horizontal. At this time, the barrel hoop 700 is suspended above the barrel 600, maintaining a certain distance from the upper end of the barrel 600, and the axis of the barrel hoop 700 coincides with the axis of the trumpet-shaped pressing cylinder.
[0034] S4. Controlling the four lifting hydraulic cylinders 300 drives the movable pressure beam 103 to continue descending. The flared clamping cylinder moves downward accordingly, applying a uniform radial closing force to the barrel 600, gradually reducing the diameter of the upper end of the barrel 600. Simultaneously, while closing the barrel 600, the flared clamping cylinder adjusts the position of the barrel 600, ensuring that the barrel's axis coincides with the axis of the flared clamping cylinder, avoiding unilateral force due to initial placement deviations. As the movable pressure beam continues to descend, the barrel plates gradually close from the edge to the center, and the barrel's end diameter decreases uniformly along a preset trajectory. During this process, the ball bearings embedded in the barrel wall roll against the outer wall of the barrel, converting sliding friction into rolling friction. This reduces the risk of wear on the barrel surface and makes the closing process more stable and controllable.
[0035] More specifically, the four lifting hydraulic cylinders 300 are controlled to extend synchronously, driving the movable pressure beam 103 to descend smoothly along the four guide columns 104; the movable pressure beam 103 drives the horn-shaped clamping cylinder to move down synchronously, and the inner wall of the clamping cylinder contacts the outer periphery of the barrel 600, applying a radial contracting force to the barrel body; the barrel plate of the wooden barrel 600 moves inward under the contracting force, and the upper diameter of the barrel 600 gradually decreases; the movable pressure beam 103 continues to descend to the predetermined position, at which point the upper diameter of the barrel 600 has been reduced to less than the inner diameter of the barrel hoop 700.
[0036] S5. When the upper diameter of barrel 600 decreases to be smaller than the inner diameter of barrel hoop 700, the claw 800 pulls barrel hoop 700 down to the outer edge of the upper part of barrel 600. (Reference) Figure 7 As shown; During the downward movement of the movable pressure beam 103, the claw 800 pulls the barrel hoop 700 down to the outer periphery of the upper end of the barrel 600. At this time, the claw 800 can be moved outward to release the clamping of the barrel hoop 700. The barrel hoop 700 slides down along the inclined surface of the trumpet-shaped clamping cylinder by its own weight and is fitted into the upper end of the barrel 600. S6. Control the telescopic hydraulic cylinder 900 to drive the two semi-conical cylinders 200 to move in the opposite direction to the open state, thereby releasing the radial constraint on the end of the barrel 600. S7. Control the four lifting hydraulic cylinders 300 to retract synchronously, drive the movable pressure beam 103 to move upward and reset, drive the claw 800 and the trumpet-shaped clamping cylinder to leave the end of the barrel 600, and move the barrel 600 with the barrel hoop 700 pressed into place out of the platform through the conveying mechanism 400.
