Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of material processing and forming, specifically to a panel pressing device. Background Technology
[0002] The panels of semi-trailers, trucks, and other transport equipment are textured. The texture increases friction between the panel and the transported goods. In addition, the texture enhances the compressive strength and deformation resistance of the panels, thus extending their service life.
[0003] The patterns on the side panels are typically pressed using a hydraulic press. This press mainly consists of a hydraulic cylinder, a lower mold, and an upper mold. The hydraulic cylinder drives the upper mold towards the lower mold, thus pressing the side panel placed on the lower mold. Simultaneously, workers manually place different positions of the side panel onto the lower mold to press the patterns onto different areas of the panel. However, manual labor is inefficient and time-consuming. Utility Model Content
[0004] In view of this, the present invention provides a panel pressing device to solve the problem of manually placing different positions of the panel on the lower mold to press the texture at different positions of the panel. However, manual work is inefficient and time-consuming.
[0005] In a first aspect, the panel pressing device provided in this application includes: frame; A conveying drive unit is connected to the frame and is used to drive the workpiece to be pressed to move in a first direction; The pressing assembly includes a first driving member, a second driving member, a first mold, and a second mold. The first driving member is connected to the frame and the first mold, respectively. The second driving member is connected to the frame and the second mold, respectively. The first driving member has a pressing state in which it drives the first mold to move in a second direction to move the area to be pressed on the workpiece away from the conveying driving member, and a reset state in which it drives the area to be pressed closer to the conveying driving member. The second driving member can drive the second mold away from or closer to the first mold.
[0006] Beneficial effects: The conveyor drive unit can transport different areas to be pressed from the workpiece to the first mold without manual handling, thereby improving transportation efficiency, reducing transportation time, and lowering labor intensity. When pressing is required, the conveyor drive unit transports the area to be pressed to the first mold. The first drive unit moves the first mold in a second direction to move the area to be pressed away from the conveyor drive unit, avoiding the conveyor drive unit bearing some of the pressing force. After the area to be pressed is away from the conveyor drive unit, the second drive unit moves the second mold closer to the first mold and performs the pressing operation on the area to be pressed. After the pressing operation is completed, the second drive unit moves the second mold away from the first mold for a reset operation, preparing for subsequent pressing operations. The conveyor drive unit can also transport the pressed area out of the first mold without manual removal, further reducing labor intensity and improving work efficiency.
[0007] In one alternative embodiment, the first mold is a concave mold and the second mold is a convex mold.
[0008] Beneficial effects: The second driving component moves the second mold toward the first mold and presses the area to be pressed on the first mold. At this time, the punch causes the material to be pressed to flow in the die, and the die provides guidance for the flow of the material to be pressed. Since the die needs to withstand the impact force of the punch and the inner wall is subjected to radial tension, the punch impacts the die during the pressing process to press and shape the material.
[0009] In one alternative embodiment, the first driving component is a first hydraulic cylinder, the cylinder body of the first hydraulic cylinder is fixedly connected to the frame, and the telescopic end of the first hydraulic cylinder is fixedly connected to the first mold; the second driving component is a second hydraulic cylinder, the cylinder body of the second hydraulic cylinder is fixedly connected to the frame, and the telescopic end of the second hydraulic cylinder is fixedly connected to the second mold.
[0010] Beneficial effects: Hydraulic cylinders can generate large linear thrust through Pascal's principle, which facilitates the lifting of the first mold and the area to be pressed on it. Furthermore, this linear thrust can be used to complete the pressing operation of the area to be pressed. In addition, hydraulic cylinders can also improve the pressing accuracy.
[0011] In one optional embodiment, the conveying drive includes a first belt conveyor and a second belt conveyor spaced apart, with the first mold located between the first belt conveyor and the second belt conveyor; The first belt conveyor includes a first conveyor belt; The second belt conveyor includes a second conveyor belt, which is spaced apart from the first conveyor belt. The two sides of the workpiece to be pressed abut against the first conveyor belt and the second conveyor belt, respectively.
[0012] Beneficial effects: The belt conveyor has a simple structure and low cost, and can transport the parts to be pressed over long distances, meeting the conveying requirements for pressing at different positions of the box plate. When the area to be pressed is stuck in the die, even if the belt continues to rotate, the parts to be pressed cannot continue to move in the first direction. At this time, the parts to be pressed slide against the belt surface, preventing the parts to be pressed from being continuously transported to the first die, which would damage the pressed structure.
[0013] In one alternative embodiment, a first adjusting member is further included, which is connected to the frame and located near the feed inlet of the conveying drive member, for driving the workpiece to be pressed to move in a third direction.
[0014] Beneficial effects: The first adjusting component drives the part to be pressed to move along a third direction, so that the part to be pressed can move to a set position, thereby enabling the conveying drive component to convey the area to be pressed to a designated position on the first mold, thus making the pressed texture within the designated area and improving the pressing accuracy.
[0015] In an alternative embodiment, a second adjustment member is further included, which is connected to the frame and located near the first mold, for moving the workpiece to be pressed in a third direction.
[0016] Beneficial effects: The second adjusting component moves the part to be pressed along a third direction, so that the area to be pressed moves to the designated position on the first mold, avoiding deviation in the position of the pressed texture. The second adjusting component can also limit the part to be pressed to prevent the part to be pressed from deviating in position during the pressing process, thereby causing deviation in the position of the pressed texture.
[0017] In an alternative embodiment, a third adjusting member is further included, which is connected to the frame and located near the discharge port of the drive member, for driving the workpiece to be pressed to move in a third direction.
[0018] Beneficial effect: The first adjusting component drives the part to be pressed to move along a third direction, so that the part to be pressed can move to the set position, thereby enabling the conveying drive component to deliver to the designated position and avoiding positional deviation of the part to be pressed.
[0019] In an alternative embodiment, a shock-absorbing pad is also included, which is located at the bottom of the frame.
[0020] Beneficial effects: The shock-absorbing pads can reduce vibration and impact during the pressing process. Attached Figure Description

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0028] The following is in conjunction with the appendix Figures 1-5 This describes an embodiment of the panel pressing device of this utility model.
[0029] This utility model provides a panel pressing device, comprising a frame 100, a conveying drive 200, and a pressing assembly. The conveying drive 200 is connected to the frame 100 and is used to drive the workpiece 600 to be pressed to move in a first direction, which is the transport direction. The pressing assembly includes a first drive 301, a second drive 303, a first mold 302, and a second mold 304. The first drive 301 is connected to the frame 100 and the first mold 302, respectively. The second drive 303 is connected to the frame 100 and the second mold 304, respectively. The first drive 301 has a pressing state in which it drives the first mold 302 to move in a second direction to move the area to be pressed on the workpiece 600 away from the conveying drive 200, and a reset state in which it drives the area to be pressed to move closer to the conveying drive 200. The second drive 303 can drive the second mold 304 away from or closer to the first mold 302.
[0030] In this embodiment, the conveying drive 200 can transport different areas to be pressed on the workpiece 600 to the first mold 302 without manual handling, thereby improving transportation efficiency, reducing transportation time, and reducing labor intensity. When pressing is required, the conveying drive 200 transports the areas to be pressed to the first mold 302. The first drive 301 drives the first mold 302 to move in the second direction, so that the areas to be pressed on it are moved away from the conveying drive 200, avoiding the conveying drive 200 bearing part of the pressing force. After the areas to be pressed are moved away from the conveying drive 200, the second drive 303 drives the second mold 304 to move closer to the first mold 302 and performs the pressing operation on the areas to be pressed on it. After the pressing operation is completed, the second drive 303 drives the second mold 304 away from the first mold 302 for a reset operation to prepare for subsequent pressing operations. The conveying drive 200 can also transport the pressed areas out of the first mold 302 without manual removal, further reducing labor intensity and improving work efficiency.
[0031] In this embodiment, as Figure 1 As shown, the frame 100 is assembled from crossbeams and columns. The crossbeams refer to all the horizontal bars in the frame 100, and the columns refer to all the vertical bars. Both the crossbeams and columns are made of high-strength steel plates or aluminum alloys to meet the load-bearing requirements, provide installation space for other components, and provide support.
[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 4As shown, the conveying drive unit 200 includes a first belt conveyor 201 and a second belt conveyor 202 spaced apart. The first belt conveyor 201 includes a motor, a first pulley 2011, a second pulley 2012, a driven shaft, and a first conveyor belt 2013. The motor housing is fixedly connected to the frame 100 by bolts, and the motor output shaft is rotatably connected to the frame 100. The first pulley 2011 is sleeved on the outer circumference of the output shaft and fixedly connected to the output shaft by a key. Both ends of the driven shaft are rotatably connected to the frame 100, and the driven shaft is spaced apart from the first pulley 2011. The height of the driven shaft is equal to that of the output shaft. The driven pulley shaft is parallel to the length direction of the output shaft. The second pulley 2012 is sleeved on the outer circumference of the driven pulley shaft and fixedly connected to it. A belt is wound around the first pulley 2011 and the second pulley 2012. The motor drives the output shaft to rotate, thereby driving the first pulley 2011 to rotate. The first pulley 2011 drives the second pulley 2012 to rotate through the first conveyor belt 2013. The belt is made of high-strength rubber material, and its surface has strip-shaped protrusions to increase the friction with the workpiece 600 to be pressed, ensuring the stability of the conveying. The motor is preferably a servo motor to more accurately control the conveying speed. The second belt conveyor 202 includes a second conveyor belt, which is spaced apart from the first conveyor belt 2013. The workpiece 600 to be pressed is a box plate, which is a rectangular plate. The two sides of the workpiece 600 to be pressed abut against the first conveyor belt 2013 and the second conveyor belt, respectively. The second belt conveyor 202 has the same structure and installation method as the first belt conveyor 201, and will not be described again here. Through the coordinated action of the first conveyor belt 2013 and the second conveyor belt (i.e., the first and second conveyor belts are in the same direction), the workpiece 600 to be pressed is stably moved towards the first direction, which is the conveying direction. The conveying path of the workpiece 600 passes through the pressing assembly. Their combined operation ensures the workpiece 600 is conveyed smoothly, avoiding deviation and ensuring the accuracy of subsequent pressing operations. The belt conveyor has a simple structure and low cost, and can transport the workpiece 600 over long distances, meeting the conveying requirements for pressing at different positions on the panel. When the area to be pressed is stuck in the die, even if the belt continues to rotate, the workpiece 600 cannot continue to move towards the first direction. At this time, the workpiece 600 slides against the belt surface, preventing the workpiece 600 from continuously being conveyed onto the first die, thus avoiding damage to the pressed structure.
[0033] In an alternative embodiment, the conveying drive 200 is a roller conveyor, which includes a plurality of spaced rollers mounted on the frame 100 via bearings and driven to rotate by a motor via a chain or belt. The surface of the rollers is patterned to increase the friction between the rollers and the workpiece 600 to be pressed. This conveying method can also move the workpiece 600 to be pressed in the first direction.
[0034] like Figure 3 As shown, the first driving component 301 in the pressing assembly is a first hydraulic cylinder. The cylinder body of the first hydraulic cylinder is fixedly connected to the frame 100, typically using bolts for fastening to ensure a stable connection. The telescopic end of the first hydraulic cylinder is fixedly connected to the first mold 302. When the first hydraulic cylinder extends or retracts, it drives the first mold 302 to move. The first mold 302 is a concave mold with a specific textured shape inside. These textures will press onto the workpiece 600 to be pressed. The concave mold is generally made of high-strength alloy steel to withstand the enormous pressure during the pressing process. In this embodiment, the texture is clover-shaped; however, different textures can be used as needed. The first driving component 301 can also be an electric push rod, a crank-slider mechanism, a linear motor, or other devices capable of linear motion. Figure 5 As shown, the second driving component 303 is a second hydraulic cylinder, and the cylinder body of the second hydraulic cylinder is fixedly connected to the frame 100. The telescopic end of the second hydraulic cylinder is fixedly connected to the second mold 304, which is a punch. The shape of the punch matches the die, and when the two are engaged, the desired texture can be pressed out. The punch is also made of high-strength alloy steel. When pressing is required, the first hydraulic cylinder drives the first mold 302 to move in the second direction (upward), which is the vertical direction. This moves the area to be pressed on the workpiece 600 away from the conveying driving component 200, preventing the conveying driving component 200 from bearing the pressing force. Then, the second hydraulic cylinder drives the second mold 304 closer to the first mold 302 to press the area to be pressed. The hydraulic cylinder can generate a large linear thrust through Pascal's principle, which facilitates the lifting of the first mold 302 and the area to be pressed on it. Using this linear thrust, the pressing operation of the area to be pressed can be completed. In addition, the hydraulic cylinder can also improve the pressing accuracy. The second driving component 303 drives the second mold 304 to move toward the first mold 302 and presses the area to be pressed on the first mold 302. At this time, the punch causes the material to be pressed to flow in the die, and the die provides guidance for the flow of the material to be pressed. Since the die needs to withstand the impact force of the punch and the inner wall is subjected to radial tension, the punch impacts the die during the pressing process to press and shape the material.
[0035] In this embodiment, the panel pressing device further includes a first adjusting component. The first adjusting component is connected to the frame 100 and located near the feed inlet of the conveying drive component 200. The first adjusting component consists of a pneumatic cylinder and a push block. The cylinder body of the pneumatic cylinder is fixedly connected to the frame 100 by bolts. The telescopic rod of the pneumatic cylinder passes through the frame 100 and extends above the first belt conveyor 201. A push block is welded and fixed to the end of the telescopic rod away from the cylinder body. The pneumatic cylinder drives the telescopic rod to move, thereby driving the push block to move along a third direction, which is the width direction of the part to be pressed 600. The first adjusting component 401 can drive the part to be pressed 600 to move along the third direction to achieve the adjustment of the initial position of the part to be pressed 600.
[0036] Furthermore, two first adjustment members 401 are provided, which are arranged opposite to each other, and the part to be pressed 600 is arranged between the two first adjustment members 401. The two push blocks are close to each other to clamp the part to be pressed 600, thereby limiting the initial position of the part to be pressed 600. The first adjustment members also drive the part to be pressed 600 to move along a third direction, so that the part to be pressed 600 moves to the set position, thereby enabling the conveying drive member 200 to convey the area to be pressed to the designated position on the first mold 302, thereby making the pressed texture within the designated area and improving the pressing accuracy.
[0037] In this embodiment, a second adjusting member 402 and a third adjusting member 403 are also included. The composition and installation method of the second adjusting member 402 and the third adjusting member 403 are the same as those of the first adjusting member 401, and will not be described again here. The second adjusting member is connected to the frame 100 and is located near the first mold 302. It is used to drive the workpiece 600 to be pressed to move along a third direction. The number of second adjusting members 402 can be one, two, or more. By driving the workpiece 600 to be pressed to move along a third direction through the second adjusting member, the area to be pressed is moved to the designated position on the first mold 302, so as to avoid deviation in the position of the pressed texture. The second adjusting member can also limit the workpiece 600 to be pressed to prevent the workpiece 600 from deviating in position during the pressing process, thereby causing deviation in the position of the pressed texture. The third adjusting member is connected to the frame 100 and is located near the discharge port of the drive member. It is used to drive the workpiece 600 to be pressed to move along a third direction. The number of third adjusting members can be one, two, or more. The first adjusting component drives the piece to be pressed 600 to move along a third direction, so that the piece to be pressed 600 moves to a set position, thereby enabling the conveying drive component 200 to convey it to the designated position and avoid positional deviation of the piece to be pressed 600.
[0038] In this embodiment, the bottom of the frame 100 is also provided with a shock-absorbing pad 500. The shock-absorbing pad 500 is generally made of elastic materials such as rubber or silicone, which can effectively reduce vibration and impact during the pressing process, extend the service life of the equipment, and also reduce noise pollution.
[0039] The implementation principle of this embodiment is as follows: the conveying drive unit 200, composed of the first belt conveyor 201 and the second belt conveyor 202, stably transports the workpiece 600 to be pressed to the pressing area, eliminating the need for manual handling and improving transportation efficiency. During pressing, the first hydraulic cylinder drives the first mold 302 to lift the area to be pressed, preventing the conveying drive unit 200 from being stressed. The second hydraulic cylinder drives the second mold 304 to cooperate with the first mold 302 for pressing. The first, second, and third adjusting components ensure the accuracy of the position of the workpiece 600 to be pressed, improving the pressing quality. The shock-absorbing pads 500 reduce vibration and impact during the pressing process. Compared with traditional manual handling and pressing methods, this device greatly improves work efficiency, reduces labor intensity, and improves product quality, representing a significant improvement over existing panel pressing technology.
