Description

Technical Field

[0001] The utility model relates to the technical field of welded pipe molds, and specifically relates to a device for deforming and trimming a material frame of a welded pipe mold. Background Art

[0002] The main reason for the deformation of the material frame of the welded pipe mold that needs to be trimmed is that the deformation will directly affect the processing accuracy of the mold and the quality of the welded pipe products, and may cause problems such as inaccurate dimensions of the welded pipe and non-compliance with the required shape. Through trimming, the original shape and size of the mold material frame can be restored, ensuring the accuracy and stability of the mold, thereby guaranteeing the quality and production efficiency of the welded pipe products. In addition, trimming can also extend the service life of the mold and reduce the costs generated by frequent mold replacement.

[0003] The utility model with the authorization publication number of CN211360162U provides a device for deforming and trimming a material frame of a welded pipe mold, which belongs to the technical field of "welded pipe mold technology", and the protected claims are: "including a material frame, the material frame includes a frame bottom, vertical frame side parts are arranged around the frame bottom, the frame bottom includes a plurality of transverse rods and longitudinal rods, each transverse rod and each longitudinal rod are arranged in a staggered manner, the frame side parts include a plurality of horizontal rods and vertical rods, each horizontal rod and each vertical rod are arranged in a staggered manner, the transverse rods, longitudinal rods, horizontal rods and vertical rods are all bent outward, a fuselage is correspondingly arranged with the material frame, the fuselage includes a bottom plate and a top plate arranged corresponding to each other up and down, a support assembly is vertically arranged between the bottom plate and the top plate, an installation seat is vertically arranged on the top plate, an air hammer is installed on the lower side of the installation seat, the air hammer is connected with an air inlet controller, a buffer seat is arranged on the bottom plate, and the hammer head of the air hammer is arranged corresponding to the material frame. The utility model can trim and reset the deformed material frame of the welded pipe mold."

[0004] In this device, although the material frame can be trimmed and reset, since the material frame itself has already deformed, if it is trimmed directly without bottom support, its original shape cannot be effectively restored, and even the deformation will be further aggravated due to uneven force during the trimming process. Therefore, we propose a device for deforming and trimming a material frame of a welded pipe mold. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1-4 shown, in this embodiment, a device for deforming and trimming a welding pipe die material frame includes a frame 1, a driving component 3, a supporting component 2, and a clamping component 4. The driving component 3 is arranged on the frame 1, the supporting component 2 is arranged on the driving component 3, and the clamping component 4 is arranged on the frame 1.

[0027] The supporting component 2 includes a hydraulic rod 201 and a telescopic rod 208. The hydraulic rod 201 is arranged on the driving component 3. The driving end of the hydraulic rod 201 is rotatably connected to a rotating shaft 202. Both ends of the rotating shaft 202 are fixedly connected with connecting blocks 203. The top of the two connecting blocks 203 is fixedly connected with an arc-shaped plate 204. One end of the bottom of the arc-shaped plate 204 is fixedly connected with a rotating block 205. The outside of the rotating block 205 is rotatably connected with an inclined strut 206. A groove 207 is opened outside the driving end of the hydraulic rod 201. The telescopic rod 208 is fixedly connected in the groove 207. The bottom end of the inclined strut 206 is rotatably connected to the top end of the telescopic rod 208. Support blocks 101 are fixedly connected to the four corners of the bottom of the frame 1.

[0028] During specific implementation, after moving to a specific position, start the supporting component 2. Specifically, start the hydraulic rod 201. The hydraulic rod 201 drives the arc-shaped plate 204 to top against the deformed area. The inclined struts 206 at both ends of the arc-shaped plate 204 will change along with the shape of the deformed area. The two inclined struts 206 drive the arc-shaped plate 204 to change the curvature through the action of the telescopic rod 208 to adapt to the shape of the deformed area for better support. Then start the hydraulic hammer 311. The hydraulic hammer 311 hammers the deformed area to trim it perfectly. During hammering, due to the supporting action of the arc-shaped plate 204, it can be avoided that further deformation will be aggravated due to uneven stress during the trimming process. It should be noted that a damping mechanism is arranged in the telescopic rod 208 to avoid repeated back vibration. The telescopic rod 208 is a prior art and will not be elaborated too much.

[0029] Embodiment 2

[0030] In this embodiment, the driving assembly 3 includes a first column 301, a first motor 303, a second column 306 and a second motor 308; the first column 301 is fixedly connected to the frame 1, and a first empty slot 302 is opened in the first column 301; the first motor 303 is fixedly connected to one end of the first column 301, the driving end of the first motor 303 extends into the first empty slot 302 and is fixedly connected to the first screw 304, and the first screw 304 is externally threadedly connected to the first moving block 305; the second column 306 is fixedly connected to the top of the first moving block 305, and a second empty slot 307 is opened in the second column 306; the second motor 308 is fixedly connected to one end of the second column 306, the driving end of the second motor 308 extends into the second empty slot 307 and is fixedly connected to the second screw 309, and the second screw 309 is externally threadedly connected to the second moving block 310, and the top of the second moving block 310 is fixedly connected to the hydraulic rod 201.

[0031] During specific implementation, the two first motors 303 are started, and the first motor 303 drives the first screw 304 to rotate, thereby driving the first moving block 305 to move linearly in the X-axis direction, that is, driving the hydraulic hammer 311 and the support assembly 2 to move linearly in the X-axis direction, and then the two second motors 308 are started, and the second motor 308 drives the second screw 309 to rotate, thereby driving the second moving block 310 to move linearly in the Y-axis direction, so that the hydraulic hammer 311 and the support assembly 2 can be driven to move to any position of the material frame for trimming.

[0032] Embodiment 3

[0033] In this embodiment, the clamping assembly 4 includes a connecting plate 401, a first clamping plate 403, a second clamping plate 404 and a fixing rod 405; the connecting plate 401 is fixedly connected to the inner side of the frame 1, and a slide groove 402 is provided on the inner side of the connecting plate 401; the first clamping plate 403 is arranged on the inner side of the connecting plate 401, and one end of the first clamping plate 403 is slidingly connected to the slide groove 402; the second clamping plate 404 is fixedly connected to the inner side of the connecting plate 401; the two fixing rods 405 are both threadedly connected in the first clamping plate 403 and the second clamping plate 404.

[0034] In specific implementation, the two ends of the material frame are clamped between the two sets of first clamping plates 403 and the second clamping plates 404, and then the two sets of fixing rods 405 are rotated to fix the two ends of the material frame, which can adapt to material frames of different thicknesses.

[0035] Working principle: First, clamp the material frame through the clamping component 4, and then start the two driving components 3 to drive the hydraulic hammer 311 and the supporting component 2 to move to any position of the material frame for trimming. After moving to the specific position, start the supporting component 2. Specifically, start the hydraulic rod 201, and the hydraulic rod 201 drives the arc plate 204 to abut against the deformed area. The inclined struts 206 at both ends of the arc plate 204 will change along with the shape of the deformed area. The two inclined struts 206 drive the arc plate 204 to change the curvature through the action of the telescopic rod 208 to adapt to the shape of the deformed area for better support. Then start the hydraulic hammer 311, and the hydraulic hammer 311 hammers the deformed area to trim it perfectly. During hammering, due to the supporting effect of the arc plate 204, it can be avoided that the deformation is further aggravated due to uneven force during the trimming process.
