Description

Technical Field

[0001] This utility model relates to the technical field of door production equipment, and in particular to a feeding mechanism for a door frame punching die retraction device. Background Technology

[0002] In the manufacturing process of door frames, the door frame generally needs to be cut according to the size of different doors before welding. At present, most of the door frames are cut using circular saws or corner cutting machines. However, the cutting efficiency of these machines is slow, and the cut door frame may have burrs or unevenness due to differences in manual operation.

[0003] Using a punching die (i.e., a door frame punching die retraction device) to punch the door frame can improve processing efficiency, and is also simple and safe to operate. In the existing technology, the punching die (patent publication number CN207839739U) is manually loaded. Because the profile is long, it needs to be manually straightened to maintain its level after loading. However, manual straightening cannot guarantee that the profile will always be level. When the profile tilts, the cut at the forming point will inevitably tilt, leading to product scrap. Furthermore, manual straightening is physically demanding for workers. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a feeding mechanism for a door frame punching die retraction device. The profile is supported by a detachable support rail, which ensures that the end of the profile deflects during processing and that the profile remains horizontal. At the same time, the height of the support rail can be adjusted according to the position of the door frame punching die retraction device, and the limiting block set on the support rail can also position the profile during the forming process.

[0005] The objective of this utility model is achieved through the following technical solution:

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1-3 This utility model provides a technical solution:

[0025] Example:

[0026] like Figures 1-3 As shown, a feeding mechanism for a door frame die retraction device includes a first support block 1, a second support block 2, and a support rail 3. The first support block 1 is detachably connected to the guide block 5 of the door frame die retraction device via a quick-connect assembly. The quick-connect assembly includes a connecting block 7, which is fixed to the guide block 5 of the door frame die retraction device by screws. The connecting block 7 has an I-shaped insertion groove 8 along its vertical edge. The first support block 1 is provided with an insertion block 9 that is adapted to the insertion groove 8. The first support block 1 is inserted into the connecting block 7 via the insertion block 9 and the insertion groove 8.

[0027] The second support block 2 is supported on the ground by a connecting rod, and the support track 3 is an inclined L-shaped plate. The connecting rod includes a sleeve 10 and a screw 11. The first end of the sleeve 10 is fixedly connected to the second support block 2, and the screw 11 is threadedly connected to the second end of the sleeve 10. The sleeve 10 and the screw 11 form a telescopic structure, which facilitates the adjustment of the height of the second support block 2 according to the position of the first support block 1. A pad 12 is provided at the end of the screw 11 away from the sleeve 10. The pad 12 is used to increase the contact area between the connecting rod and the ground, thereby improving its stability during support.

[0028] The first support block 1 and the second support block 2 are respectively provided with L-shaped support grooves 6 that are adapted to the support rail 3. The two ends of the support rail 3 are respectively set on the first support block 1 and the second support block 2 through the support grooves 6. The support rail 3 is horizontally arranged and has a support surface for supporting the profile 4. A limiting block 13 is slidably provided on the support rail 3. The limiting block 13 is provided with a threaded hole, and a bolt is provided in the threaded hole. The end of the bolt abuts against the support rail 3.

[0029] Among them, 1. The first support block 1 and the plug-in block 9 are an integrated structure.

[0030] In use, after the connecting block 7 is fixed to the guide block 5 with screws, the first support block 1 is inserted into the insertion slot 8 through the insertion block 9, so as to realize the detachable connection between the first support block 1 and the guide block 5.

[0031] After the first support block 1 is in place, the height of the second support block 2 is adjusted by rotating the screw 11 or the sleeve 10, with the first support block 1 as the reference, so that the first support block 1 and the second support block 2 are on the same horizontal plane and the support grooves 6 on the first support block 1 and the second support block 2 are parallel.

[0032] After the second support block 2 is in place, the two ends of the support rail 3 are placed on the first support block 1 and the second support block 2 respectively, and the support rail 3 completes its support function. Then, the profile 4 is placed into the support rail 3. After the profile 4 is fed into the die along the support rail 3, the sliding limit block 13 is moved so that the side of the limit block 13 near the guide block 5 abuts against the profile 4, thereby positioning the profile 4. After the limit block 13 is in place, the bolts are tightened, and the bolt ends contact the support rail 3, locking the two together through friction. Then, normal profile 4 forming can begin. The profile 4 forming process is existing technology and will not be described in detail here.

[0033] This invention supports the profile by setting a detachable support rail, ensuring that the end of the profile deflects during processing and that the profile remains horizontal. At the same time, the height of the support rail can be adjusted according to the position of the door frame die retraction device, and the limiting block set on the support rail can also position the profile during the forming process.

[0034] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
