Description

Technical Field

[0001] This utility model relates to the field of fire-resistant window PVC profile production and processing technology, specifically a shaping table for fire-resistant window PVC profile production. Background Technology

[0002] In the production process of PVC profiles, it is often necessary to inspect the profiles to ensure that their length, width, thickness, and hole positions are standard and in place. However, many inspection stations only serve an inspection function, and the hole diameter inspection is merely a matter of manually visually aligning the drilled holes after alignment. This can easily lead to insufficient verification accuracy and makes it impossible to correct PVC profiles with improperly drilled holes. Furthermore, the shaping and drilling of PVC profiles are core processes that directly affect the subsequent assembly accuracy and the quality of the finished product.

[0003] Based on the above problems, there is an urgent need for a shaping table for the production of fire-resistant PVC window profiles to meet the needs of fire-resistant PVC window profiles in terms of inspection and hole correction. Utility Model Content

[0004] The purpose of this utility model is to provide a shaping table for the production of fire-resistant PVC window profiles, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shaping table for producing fire-resistant window PVC profiles, including a frame spanning the outside of the operating table, a drilling assembly and a light source installed on the top of the frame, the drilling assembly including a first hydraulic cylinder, the first piston rod of the first hydraulic cylinder being arranged downwards, and a drilling rod being fixedly connected to the movable end of the first piston rod;

[0006] The operating table is provided with calibration holes, and a photoelectric sensor is provided below the calibration holes. On both sides of the operating table, there are vertically installed limiting clamps for clamping the profile to be shaped. The lower middle end of the limiting clamp is provided with a clamping groove. The width of the clamping groove is the height of the profile to be shaped. The distance between the two limiting clamps is the width of the profile to be shaped. A locking screw is provided behind the conveying of the limiting clamp. The locking screw is threaded into the operating table from the bottom upward. The tail end of the locking screw is higher than the table surface of the operating table and lower than the bottom end of the clamping groove. During assembly, the top of the locking screw is screwed into a stop bar, and the stop bar abuts against the rear of the conveying of the limiting clamp.

[0007] The front end of the conveyor of the operating table is provided with a feeding assembly. The feeding assembly includes an upright mounting plate, on which a second hydraulic cylinder is mounted. The movable end of the second piston rod is provided with an L-shaped material-bearing push plate. The L-shaped material-bearing push plate is open at the top and also open on the rearward side. The L-shaped material-bearing push plate includes side plates arranged around three sides. The side plates are mounted on the top of the base plate. The base plate is provided with at least two sliding grooves. A third hydraulic cylinder is installed on the inner side of the L-shaped material-bearing push plate. The third hydraulic cylinder and the second hydraulic cylinder form a two-stage push. A push plate is detachably provided on the movable end of the third piston rod of the third hydraulic cylinder. A push block is provided on the push plate facing the bottom of the sliding groove.

[0008] Preferably, the bottom of the drilling rod is provided with a drilling tip to facilitate drilling.

[0009] Preferably, the photoelectric sensor is mounted on a support beam at the bottom of the frame for easy support.

[0010] Preferably, the end of the locking screw is fitted with a protective gasket made of rubber material, which can reduce scratches on the fire-resistant PVC window profile.

[0011] Preferably, the push block is vertically disposed at the bottom of the push plate, and the push plate and push block are provided with a scratch-resistant layer made of rubber material in the direction facing the profile to be shaped.

[0012] Preferably, the bottom plate has a rounded chamfer on the side facing the rear of the conveyor to facilitate the delivery of the profile to be shaped.

[0013] Preferably, the height of the base plate is the same as the height of the clamping opening at the bottom of the clamping groove, which facilitates pushing the profile to be shaped into the clamping groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Linkage calibration is achieved through photoelectric sensors. The calibration hole position and photoelectric sensors form a closed-loop feedback. When the profile to be shaped is transported to the calibration hole position, the photoelectric sensors detect the hole position on the profile in real time to determine whether there is any obstruction or hole position deviation. Then, it is determined whether to trigger the first hydraulic cylinder to drive the drilling rod to rotate the hole. This step can effectively eliminate the error of manual judgment.

[0016] 2. The limiting clamp is locked, and the locking screw and the stop bar form an adjustable limiting mechanism to adapt to the inspection of profiles of different lengths; the stop bar abuts against the rear side of the limiting clamp to prevent the clamp from loosening due to vibration during processing.

[0017] 3. The two-stage hydraulic feeding improves stability. Through the coordination of coarse and fine adjustment, the second hydraulic cylinder drives the L-shaped material-bearing pusher to complete the coarse positioning of the profile. The third hydraulic cylinder pushes the profile along the slide groove for a second fine push through the push block, ensuring that the profile is accurately embedded in the clamping groove for alignment. This facilitates the inspection of the profile and effectively shortens the overall positioning time.

[0018] This invention integrates photoelectric sensing, hydraulic drive and mechanical limiting to achieve full automation of the "feeding-clamping-calibration-drilling" process, reducing manual operation while effectively improving the efficiency of judging and calibrating profiles.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a shaping table for producing fire-resistant window PVC profiles, including a frame 1 spanning the outside of the operating table 2. A drilling assembly 4 and a light source are installed on the top of the frame 1. The drilling assembly 4 includes a first hydraulic cylinder 41. The first piston rod 42 of the first hydraulic cylinder 41 is arranged downward. A drilling rod 43 is fixedly connected to the movable end of the first piston rod 42. A drilling tip is provided at the bottom of the drilling rod 43.

[0031] The operating table 2 is provided with calibration holes 21. A photoelectric sensor 12 is located below the calibration holes 21 and is mounted on a support beam 11 at the bottom of the frame 1. Vertically mounted limiting clamps 22 for clamping the profile 6 to be shaped are located on both sides of the operating table 2. A clamping groove 221 is located at the lower middle end of each limiting clamp 22. The width of the clamping groove 221 is the height of the profile 6 to be shaped, and the distance between the two limiting clamps 22 is the width of the profile 6 to be shaped. A locking screw 3 is provided behind the conveying position clamp 22. The locking screw 3 is threaded into the operating table 2 from the bottom upward. The tail end of the locking screw 3 is higher than the table surface of the operating table 2 and lower than the bottom end of the clamping groove 221. A protective gasket 31 made of rubber material is attached to the end of the locking screw 3 to prevent the profile from being scratched when moving it later. When the locking screw 3 is assembled, the top of it is screwed into the stop rod 5, and the stop rod 5 abuts against the rear of the conveying position clamp 22.

[0032] The front end of the conveying platform 2 is equipped with a feeding assembly 7. The feeding assembly 7 includes an upright mounting plate 72, on which a second hydraulic cylinder 71 is mounted. An L-shaped material-bearing pusher 74 is located at the movable end of the second piston rod 73. The L-shaped material-bearing pusher 74 has an opening at the top and also an opening on the rearward side. The L-shaped material-bearing pusher 74 includes side plates 742 arranged on three sides, which are mounted above a base plate 745. The base plate 745 has at least two sliding grooves 741. A third hydraulic cylinder 75 is mounted on the inner side of the L-shaped material-bearing pusher 74. The third hydraulic cylinder 75 forms a two-stage push with the second hydraulic cylinder 71. The movable end of the third piston rod 76 of the third hydraulic cylinder 75 is detachably provided with a push plate 77. The push plate 77 is provided with a push block 771 facing the bottom of the slide groove 741. The push block 771 is vertically arranged at the bottom of the push plate 77. The push plate 77 and the push block 771 are provided with a scratch-resistant layer made of rubber material facing the profile 6 to be shaped. In order to facilitate the ejection of the profile, the bottom plate 745 is provided with an arc chamfer on the side facing the rear of the conveyor. The height of the bottom plate 745 is consistent with the height of the bottom clamping opening of the clamping groove 221, so as to facilitate the precise alignment of the profile when it is ejected.

[0033] One specific application of this embodiment is: before use, screw the stop bar into the locking screw, select a suitable locking screw and screw it in. It should be noted that the distance between the front end of the limit baffle and the stop bar is the length of the profile to be measured. That is, when the profile to be shaped is pushed into the clamping groove and aligned with the front end of the limit baffle, it can be determined by observation whether the length of the profile is the standard length.

[0034] In use, the first step is to feed and roughly position the profile. The operator places the profile to be shaped into the L-shaped support plate, with the bottom of the profile adhering to the base plate and the sides limited by the side plates. The second hydraulic cylinder is activated, pushing the L-shaped support plate along the conveying direction of the operating table until the front end of the profile approaches the inlet of the clamping groove (coarse positioning completed). The third hydraulic cylinder is activated, and the third piston rod drives the push plate forward along the slide, with the push block pressing against the rear end of the profile, forcing its front end to accurately embed into the clamping groove for alignment (fine positioning completed). The height and width of the profile are determined by observing the relationship between the clamping groove and the profile. If the length of the profile to be shaped is equal to the distance between the front end of the limiting baffle and the stop bar, the length meets the standard. If the height (thickness) of the profile to be shaped is equal to the height of the clamping groove, the height of the profile to be shaped meets the standard. If the width of the profile to be shaped is equal to the distance between the two limiting clamps, the width of the profile to be shaped meets the standard. Then, the diameter of the drilled hole is checked.

[0035] The photoelectric sensor detects the deviation between the calibration hole position and the actual hole position on the profile. Under normal circumstances, the light path transmitted by the light source can be received by the photoelectric sensor. By checking whether the light path of the calibration hole position is blocked, it is determined whether there is a deviation in the processed hole position of the profile. If the light path of the hole position is blocked, it indicates that there is a problem with the hole position processing on the profile. The first hydraulic cylinder is then activated, driving the drilling rod to press down, and the drill tip penetrates the profile to complete the hole position shaping. After drilling is completed, all hydraulic cylinders are reset, the stop lever is rotated in the opposite direction to release, and the operator pulls out the profile, allowing it to leave the clamping groove and proceed to the next process. If the light path detected in this step is not blocked, the profile can be directly removed and proceed to the next process.
