Description
Technical Field
[0001] The utility model relates to the technical field of profiling processing equipment, and particularly relates to a continuous profiling device integrating conveying and profiling. Background Art
[0002] In the field of profiling processing equipment, realizing the coordinated operation of continuous material conveying and precise profiling is the key to improving production efficiency and product quality. In the prior art, the patent CN 222844868 U proposed a segmented synchronous conveying and profiling device. Through the segmented design of the feeding conveying track, the liftable track and the discharging conveying track, and combining the driving of the lower lifting cylinder to lift the track, the switching of the material conveying and profiling stations is realized. Although this scheme improves the production continuity to a certain extent, the scheme adopts a segmented track design, the carrier is separated from the chain drive assembly, and the carrier needs to be pushed intermittently by the lever of the chain drive assembly. The structure is relatively complex, and multiple components such as levers and traction chains need to be additionally arranged, increasing the mechanical complexity and significantly raising the difficulty of equipment debugging and maintenance. Content of the Utility Model
[0003] Aiming at the problems existing in the above prior art, the utility model provides a continuous profiling device integrating conveying and profiling, which simplifies the equipment structure, improves the transmission accuracy and stability while meeting the requirements of high-speed continuous production, and effectively solves the problems of low production efficiency and high maintenance cost in the prior art.
[0004] The technical scheme adopted by the utility model is as follows: A continuous profiling device integrating conveying and profiling includes a conveying component, a carrier, a lower die component, and an upper die component;
[0005] The conveying component includes two mutually parallel and spaced conveying chains, a sprocket set respectively engaged with the two conveying chains, and a transmission shaft connecting the sprocket sets on both sides. The conveying chains are driven by the sprocket set to form a step-by-step cyclic conveying path. When the carrier runs to the profiling station, the conveying chains stop moving, and continue to run step by step after profiling is completed;
[0006] Multiple groups of carriers are provided. Each group of carriers includes a number of independently arranged strip-shaped bearing bars. The two ends of the strip-shaped bearing bars are respectively connected to the chain plates on the two sides of the conveying chains through connecting seats. The carriers run step by step cyclically along with the conveying chains;
[0007] The lower die assembly includes a lower die base, a lower template fixedly installed on the lower die base, and moving guide rails symmetrically arranged on both sides of the lower template. A guide rail groove for the conveying chain to pass through is formed on one side of the moving guide rail close to the lower template. The moving guide rail is connected to the lower die base through an inclined cylinder. A guide seat is arranged outside the moving guide rail on the lower die base. A guide rod parallel to the inclined cylinder is fixedly installed on the guide seat. A guide block is fixedly connected to the moving guide rail. A guide hole matching the guide rod is formed on the guide block. A roller is rotatably installed on the guide block.
[0008] The upper die assembly includes an upper die base, an upper template fixedly installed at the bottom of the upper die base, and a ramp plate. The upper template and the lower template cooperate to form a pressing cavity. The inclined surface of the ramp plate contacts the roller when the upper die assembly moves downward, thereby driving the moving guide rail to drive the conveying chain and the carrier to move obliquely downward in the opposite direction of the conveying direction of the conveying chain until the bottom of the carrier fits with the lower template and then the die is closed for pressing.
[0009] Further, the conveying assembly further includes a chain supporting rail, which is used to support the straight section of the conveying chain located outside the upper die assembly and the lower die assembly, and there is a gap between the chain supporting rail and the moving guide rail.
[0010] Further, the roller is rotatably installed on the side surface of the guide block through a pin shaft.
[0011] Further, a linear bearing is arranged in the guide hole of the guide block.
[0012] Further, the length of each group of carriers is the same as the length of the pressing working surfaces of the upper template and the lower template, and there are gaps of two or more strip-shaped bearing bars between adjacent carriers.
[0013] Further, a plurality of material grooves for carrying single materials are arranged along the length direction on the strip-shaped bearing bar, and upper die blocks and lower die blocks corresponding to the material grooves are arranged in an array on the upper template and the lower template.
[0014] Further, a chain positioning mechanism is fixedly installed on the moving guide rail. The chain positioning mechanism includes a positioning cylinder fixedly connected to the moving guide rail. The output end of the positioning cylinder is connected with a push plate. A plurality of ejector pins are fixedly arranged at intervals on one side of the push plate close to the conveying chain. Positioning jacks corresponding to the ejector pins are arranged on the connecting seat and the chain plate.
[0015] Further, it further includes a chain adjustment assembly. The chain adjustment assembly includes two sets of sprocket groups arranged in a triangle and respectively meshed with two conveyor chains. The upper and lower sprockets of each set of sprocket groups are mounted on the lower die base through brackets. The two intermediate sprockets are connected by a transmission shaft. The transmission shaft is mounted on the moving frame through a bearing block. The moving frame is connected to an adjustment cylinder. By pushing the transmission shaft and the two sprockets connected to the transmission shaft by the adjustment cylinder, the extra length required when the conveyor chain moves obliquely downward can be compensated.
[0016] Further, chain guards are respectively arranged on the outer sides of the two intermediate sprockets of the sprocket group, and a chain support plate is arranged below the lower sprocket. The chain guards and the chain support plate are used to prevent the conveyor chain from being disengaged from the sprockets when the adjustment cylinder contracts.
[0017] The beneficial effects of the present utility model are as follows:
[0018] (1) The present utility model adopts a step-by-step cyclic movement mode of the conveyor chain. After the conveyor chain runs in place and stops, during the downward movement of the upper die assembly, through the cooperation of the ramp plate and the roller, the moving guide rail is driven to drive the carrier to move obliquely downward in the opposite direction of the conveyor until the bottom of the carrier fits with the lower template to complete mold closing and pressing. This process does not require the lifting and switching of segmented tracks, and directly realizes the seamless connection between conveying and pressing through the mechanical linkage of the chain and the mold. After pressing is completed, the tilting cylinder pushes the moving guide rail to reset, and the chain continues to move to the next station, forming a continuous cycle of "conveying - positioning - pressing - resetting", significantly improving the automation degree and production efficiency;
[0019] (2) The segmented tracks and complex chain drive components in the prior art are cancelled. The carrier is directly carried by two parallel conveyor chains. The two ends of the strip-shaped carrier bars of the carrier are connected to the chain plates of the chain. The moving guide rail realizes oblique movement through the cooperation of the tilting cylinder, the guide rod, the ramp plate and the roller, and the mechanical structure is simpler;
[0020] (3) When the moving guide rail drives the conveyor chain to move obliquely downward during the pressing process, the chain requires extra length due to the extended path. At this time, the adjustment cylinder of the chain adjustment assembly contracts synchronously, driving the transmission shaft and the intermediate sprocket to move in the direction of the slack of the chain, releasing the length of the chain, and avoiding the overload fracture of the chain caused by the sudden change of the path; after pressing is completed, the adjustment cylinder pushes the transmission shaft to reset, making the chain return to the initial tension state, ensuring the stability of subsequent conveying; the chain guard restricts the lateral offset of the chain, and the chain support plate supports the drooping chain segment, preventing the chain from being disengaged from the sprockets or getting stuck when the adjustment cylinder contracts and releases the chain length, and ensuring the reliability of the compensation action.

Detailed implementation manners
[0029] For the convenience of understanding the present utility model, the following will describe the present utility model more comprehensively and meticulously in conjunction with the accompanying drawings of the specification and preferred embodiments, but the protection scope of the present utility model is not limited to the following specific embodiments.
[0030] As Figure 1 shown, a continuous pressing device integrating conveying and pressing provided in this embodiment includes a conveyor assembly 100, a carrier 200, a lower die assembly 300, and an upper die assembly 400.
[0031] Refer to Figure 1 , Figure 2, the conveying assembly 100 provides power and guidance for the material conveying of the device. It includes two parallel and spaced conveying chains 102, and each conveying chain 102 is engaged with the corresponding sprocket set to form a stable transmission system. The sprockets arranged at corresponding positions on both sides are connected by a transmission shaft to ensure that the sprockets on both sides can rotate synchronously, thereby driving the conveying chain 102 to perform a stepping cyclic conveying motion and providing basic power for the movement of the carrier 200. When the carrier 200 runs to the pressing station, the conveying chain 102 stops moving, and continues to step and run after the pressing is completed.
[0032] See Figure 3 , multiple groups of carriers 200 are provided for carrying the materials to be processed. Each group of carriers 200 includes several independently arranged strip-shaped bearing bars 201. The two ends of the strip-shaped bearing bar 201 are respectively connected to the link plates 103 on the conveying chains 102 on both sides through the connecting seats 202, and the carrier 200 runs step by step and cyclically with the conveying chain 102.
[0033] See Figure 4 , Figure 5 , Figure 6 , the lower die assembly 300 is the lower support structure for the pressing operation, including a lower die base 301, a lower template 302 and a moving guide rail 303. The lower template 302 is fixedly installed on the lower die base 301 to provide a basic forming surface for the pressing operation. Two moving guide rails 303 are symmetrically arranged on both sides of the lower template 302. A guide rail groove is provided on one side of each moving guide rail 303 close to the lower template 302, and the two conveying chains 102 respectively pass through the guide rail grooves of the corresponding moving guide rails 303 to realize the guiding and supporting of the conveying chain 102.
[0034] The moving guide rail 303 is connected to the lower die base 301 through an inclined cylinder 308. The inclined cylinder 308 provides buffering for the downward movement of the moving guide rail 303 during pressing and driving force for the reset of the moving guide rail 303. To ensure the stability of the moving guide rail 303 during movement, a guide seat 309 is provided at the position of the lower die base 301 outside the moving guide rail 303, and a guide rod 310 parallel to the inclined cylinder 308 is fixedly installed on the guide seat 309. A guide block 311 is fixedly connected to the moving guide rail 303, and a guide hole matching the guide rod 310 is provided on the guide block 311. A linear bearing is provided in the guide hole, so that the moving guide rail 303 can perform precise oblique displacement along the guide rod 310. A roller 312 is rotatably connected to the side surface of the guide block 311 through a pin shaft.
[0035] The upper die assembly 400 is the upper force-applying structure for the pressing operation, including an upper die base, an upper template and a ramp plate 401. The upper template is fixedly installed at the bottom of the upper die base and matches the lower template to jointly form the forming cavity of the pressing die. The ramp plate 401 is also fixedly installed on the upper die base, and its position corresponds to the roller 312 of the lower die assembly.
[0036] When the upper die assembly 400 moves downward, the inclined surface of the ramp plate 401 first contacts the roller 312. As the upper die assembly 400 continues to move downward, the inclined surface of the ramp plate 401 pushes the roller 312, thereby driving the moving guide rails 303 on both sides, the conveyor chain 102, and the carrier 200 to move obliquely downward in the direction opposite to the running direction of the conveyor chain 102. This movement causes the bottom of the carrier 200 to fit against the lower template 302, providing stable support and precise positioning for the pressing operation and ensuring the pressing quality.
[0037] As Figure 1 shown, in this embodiment, the conveying assembly 100 further includes a chain supporting rail 101. The chain supporting rail 101 is used to support the straight section of the conveyor chain 102 located outside the upper die assembly 400 and the lower die assembly 300, and there is a gap between the chain supporting rail 101 and the moving guide rail 303, so as to ensure that the movement of the moving guide rail 303 is not hindered.
[0038] In this embodiment, a plurality of material grooves 203 for carrying single materials are arranged along the length direction on the strip-shaped bearing bar 201. A group of carriers 200 composed of several independently arranged strip-shaped bearing bars 201 form a plurality of material grooves 203 distributed in an array, and the length of the carrier 200 is the same as the length of the pressing working surfaces of the upper template and the lower template 302. Upper modules and lower modules 304 corresponding to the material grooves 203 are arranged in an array on the upper template and the lower template 302.
[0039] In this embodiment, there is a gap of two or more strip-shaped bearing bars 201 between adjacent two groups of carriers 200. When the moving guide rail 303 and the carrier 200 move downward during pressing, this gap forms a transition area on both sides of the carrier 200 respectively.
[0040] As Figure 4 、 Figure 5 shown, in this embodiment, a chain positioning mechanism is fixedly installed on the moving guide rail 303. The chain positioning mechanism includes a positioning cylinder 305 fixedly connected to the moving guide rail 303. The output end of the positioning cylinder 305 is connected with a push plate 306. A plurality of ejector pins 307 are fixedly arranged at intervals on the side of the push plate 306 close to the conveyor chain 102. Positioning jacks 104 corresponding to the ejector pins 307 are arranged on the connecting seat 202 and the chain plate 103. When the carrier 200 moves to the pressing station along with the conveyor chain 102, the positioning cylinder 305 drives the push plate 306 to move towards the conveyor chain 102 side, so that the ejector pins 307 are inserted into the corresponding positioning jacks 104, realizing the positioning of the conveyor chain 102 and the carrier 200 and the mechanical locking of the pressing position.
[0041] As Figure 1 、 Figure 7As shown, the continuous profiling device of this embodiment further includes a chain adjustment assembly 500, which realizes dynamic compensation of the chain length through the chain adjustment assembly 500. The chain adjustment assembly 500 includes two sets of sprocket groups arranged in a triangle and respectively meshed with two conveying chains 102. The upper and lower sprockets of each set of sprocket groups are installed on the lower die base 301 through brackets. The two intermediate sprockets are connected by a transmission shaft 501. The transmission shaft 501 is installed on a moving frame 502 through a bearing block, and the moving frame 502 is connected to an adjustment cylinder 503. When the moving guide rail 303 drives the conveying chain 102 to tilt and move downward during the profiling process, the conveying chain 102 requires additional length due to the extended path. At this time, the adjustment cylinder 503 of the chain adjustment assembly 500 contracts synchronously, driving the transmission shaft 501 and the intermediate sprocket to displace in the direction of the chain slack, releasing the chain length and avoiding the overload fracture of the chain caused by the sudden change of the path.
[0042] In this embodiment, chain guards 504 are respectively provided on the outer sides of the two intermediate sprockets of the sprocket group, and a chain support plate 505 is provided below the lower sprocket. The chain guards 504 and the chain support plate 505 are used to prevent the conveying chain 102 from being disengaged from the teeth when the adjustment cylinder contracts to release the chain length.
[0043] With the help of the teachings present in the foregoing specification and the associated drawings, those skilled in the art to which the present invention pertains will envision many modifications and other embodiments of the present invention. Accordingly, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and that modifications and other embodiments are regarded as included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
