Description

Technical Field

[0001] This utility model belongs to the field of vacuum shaping equipment, and in particular relates to a shaping table for processing plastic profiles that can be automatically positioned. Background Technology

[0002] Vacuum shaping is a common shaping method in profile processing. In vacuum shaping, the plastic profile blank is first placed into a mold. Then, a vacuum pump extracts the air between the mold cavity and the profile, creating a negative pressure environment inside the mold. Under the pressure difference, the profile blank is pressed tightly against the inner wall of the mold. Cooling is achieved using circulating water, which quickly removes the heat from the profile, allowing it to cool rapidly while maintaining its shape consistent with the mold, thus achieving the desired shape. Because the profile is constantly subject to vacuum suction and mold constraint during the cooling process, it maintains a stable shape and dimensional accuracy.

[0003] Currently, most vacuum forming equipment includes a vacuum forming section and a water cooling section, with aluminum troughs located below both sections. For example, a PVC profile cooling and forming table is disclosed in existing patent CN201721725017.9. However, this equipment lacks a structure for adjusting the forming die position, which is detrimental to its integration with profile extrusion equipment. Existing patent CN201920395316.3 discloses a vacuum forming device with an adjustable forming die position, but it employs a manual mechanical design with a low degree of automation. Utility Model Content

[0004] This invention addresses the technical problems existing in the adjustment of the aforementioned vacuum shaping table by proposing a reasonably designed, highly automated, and practical shaping table for plastic profile processing that can be automatically positioned.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an automatically positioning shaping table for processing plastic profiles, including a worktable. A pump unit is installed inside the worktable. An aluminum channel and a button for controlling the pump unit are installed on the worktable. A vacuum shaping section and a water cooling section connected to the pump unit are installed above the aluminum channel. A square tube frame for supporting the vacuum shaping section and the water cooling section is installed inside the aluminum channel. Two lead screw drive mechanisms are installed below the aluminum channel. Each lead screw drive mechanism includes a slide for lateral movement. Two pairs of clamps corresponding to the two lead screw drive mechanisms are installed at the bottom of the aluminum channel. The clamps are distributed on the sides of the slides. The connection surface between the clamps and the aluminum channel is higher than the highest level of the lead screw drive mechanism. A support plate that cooperates with the bottom support of the lead screw drive mechanism is installed between the two pairs of clamps. Two lifting cylinders distributed diagonally are installed at the bottom of the support plate.

[0006] Preferably, the clamp includes a Z-shaped segment and an L-shaped segment at the bottom of the Z-shaped segment. Multiple bolts are provided on both sides of the Z-shaped segment, some of which are used to connect the clamp to the aluminum groove and others are used to connect the clamp to the slide block. The bottom end of the L-shaped segment is in sliding fit with a side groove provided on the side of the lead screw transmission mechanism.

[0007] Preferably, the pallet is shaped like a "Z" and has a guide hole on its side, in which an anti-tilting guide rod connected to the clamp is installed.

[0008] Preferably, the pallet is provided with multiple parallel positioning strips near both ends, and the positioning strips cooperate with the bottom groove provided at the bottom of the lead screw transmission mechanism.

[0009] Preferably, the tray has multiple strip-shaped holes in the middle for weight reduction.

[0010] Preferably, at least one anti-pressure plate is provided between the pallet and the aluminum channel, and the longitudinal section of the anti-pressure plate is I-shaped and its length direction is perpendicular to the length direction of the strip hole.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This utility model provides an automatically positioned shaping table for processing plastic profiles. By installing a screw drive mechanism and a lifting cylinder at the bottom of the aluminum trough, it provides lifting and lateral positioning functions for the aluminum trough, as well as the vacuum shaping section and water cooling section. Furthermore, clamps and a support plate ensure the balance and safety of the aluminum trough during the automatic positioning process, which helps improve the automatic positioning efficiency of the equipment. This device is rationally designed, improves the degree of automation, and is highly practical, making it suitable for large-scale promotion. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figures 1-7As shown, this utility model provides an automatically positioned shaping table for processing plastic profiles, including a worktable 1. A pump unit is installed inside the worktable 1. An aluminum channel 2 and a button 3 for controlling the pump unit are provided on the worktable 1. A vacuum shaping section 4 and a water cooling section 5, connected to the pump unit, are located above the aluminum channel 2. The pump unit includes a vacuum pump, a water pump for providing hydraulic power to the lifting cylinder 10, and several valves. The corresponding power components can be activated by operating the button 3 to perform positioning and vacuum shaping operations. The vacuum shaping section 4 and the water cooling section 5 are existing mature technologies, both equipped with connecting seats for connection to the pump unit; these will not be described in detail here.

[0026] To improve the automatic positioning performance of this equipment and better connect with the thermoplastic extrusion equipment in the workshop, the aluminum trough 2 provided by this utility model is internally equipped with a square tube frame 6 for supporting the vacuum forming section 4 and the water cooling section 5. Two screw drive mechanisms 7 are installed below the aluminum trough 2. Each screw drive mechanism 7 includes a slide 71 for lateral movement. The slide 71 is threaded to the screw, and both ends of the screw are mounted on bearing seats, which are mounted on a base plate. A motor for driving the screw to rotate is also installed on the base plate. Furthermore, two pairs of clamps 8 are installed at the bottom of the aluminum trough 2, corresponding to the two screw drive mechanisms 7. The clamps 8 are distributed on the sides of the slide 71, and the connection surface between the clamps 8 and the aluminum trough 2 is higher than the highest level of the screw drive mechanism 7. A support plate 9 is installed between the two pairs of clamps 8, which supports the bottom of the screw drive mechanism 7. Two lifting cylinders 10 are arranged diagonally at the bottom of the support plate 9. The distribution characteristics of the lifting cylinder 10 allow it to be positioned on the side relative to the inside of the worktable 1 while having effective lifting drive capability, thus providing ample space for other necessary structures and electrical components inside the worktable 1.

[0027] Specifically, the mechanical structures below the aluminum trough 2 are all located inside the workbench 1. Since the two ends of the lead screw transmission mechanism 7 are usually at their highest level, due to space limitations for lateral adjustment, this equipment is specially equipped with a height-controllable clamp 8 below the aluminum trough 2 to prevent the aluminum trough 2 from hitting the bearing seat and motor of the lead screw transmission mechanism 7 in the limited lateral direction. In this way, the limited stroke of the lead screw transmission mechanism 7 inside the workbench 1 can complete the lateral adjustment of the aluminum trough 2, the vacuum forming section 4, and the water cooling section 5. Furthermore, the support plate 9 is used to support two lead screw transmission mechanisms 7 simultaneously. The lifting cylinder 10 can complete the vertical adjustment of the lead screw transmission mechanism 7, the aluminum trough 2, the vacuum forming section 4, and the water cooling section 5 through its vertical extension and retraction. The operator controls the pump group through the operation button 3 to guide the lead screw transmission mechanism 7 and the lifting cylinder 10 to complete the corresponding actions, thereby achieving automatic positioning and ensuring a better connection between the forming mold in the vacuum forming section 4 and the thermoplastic extrusion equipment, which is beneficial to ensuring product quality.

[0028] To improve the practicality of the clamp 8, the clamp 8 provided by this utility model includes a Z-shaped segment 81 and an L-shaped segment 82 located at the bottom of the Z-shaped segment 81. Multiple bolts 83 are provided on both sides of the Z-shaped segment 81. Some of the bolts 83 are used to connect the clamp 8 to the aluminum channel 2, and others are used to connect the clamp 8 to the slide block 71. The bottom end of the L-shaped segment 82 slides into a side slot 72 located on the side of the lead screw transmission mechanism 7. The bolts 83 connecting the Z-shaped segment 81 to the aluminum channel 2 are connected from bottom to top, while the bolts connecting the Z-shaped segment 81 to the slide block 71 are connected from top to bottom. The Z-shaped segment 81 provides effective installation allowance for the bolts 83, facilitating assembly. The L-shaped section 82 and the Z-shaped section 81 are integrally formed and have a certain combined height. With the side slot 72 of the screw drive mechanism 7 as the lowest support position, the top surface of the Z-shaped section 81 is higher than the highest level of the screw drive mechanism 7. Therefore, the height control function of the clamp 8 can ensure that the aluminum groove 2 will not collide with the screw drive mechanism 7 unnecessarily during the passive lateral adjustment process.

[0029] Considering that the water inside the aluminum tank 2 and the mechanical structure installed on top both have a certain weight, in order to improve the balance of the aluminum tank 2 during the lifting process, the support plate 9 provided by this utility model is shaped like a "Z". The side of the support plate 9 is provided with a guide hole 91, and an anti-tilting guide rod 11 connected to the clamp 8 is installed in the guide hole 91. In this way, the anti-tilting guide rod 11 can provide a vertical anti-tilting effect without affecting the lateral movement of the aluminum tank 2.

[0030] Furthermore, the pallet 9 provided by this utility model is provided with multiple parallel positioning strips 92 near both ends. The positioning strips 92 cooperate with the bottom groove provided at the bottom of the lead screw transmission mechanism 7. The positioning strips 92 and the bottom groove can provide anti-sway performance for the lead screw transmission mechanism 7 and the pallet 9, which is beneficial to improving the relative stability of the lead screw transmission mechanism 7 and the pallet 9.

[0031] To reduce the weight of the pallet 9, multiple strip holes 93 for weight reduction are provided in the middle of the pallet 9.

[0032] To improve the deformation resistance of the pallet 9, at least one anti-pressure plate 12 is provided between the pallet 9 and the aluminum channel 2. The longitudinal section of the anti-pressure plate 12 is I-shaped and its length direction is perpendicular to the length direction of the strip hole. The anti-pressure plate 12 can be bolted to the anti-pressure plate 12 or fixed to the anti-pressure plate 12 by welding. The balancing effect of the anti-pressure plate 12 can prevent the pallet 9 from deforming due to the fulcrum effect of the lifting cylinder 10.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
