Description

Technical Field

[0001] This application relates to the technical field of die equipment, and particularly to an attached vibration segment die. Background Art

[0002] Segments are used to cover the outside of a conveying pipeline to play a protective role and can be made of metal materials. When making segments from metal materials, it is necessary to bend a flat metal plate into a standard and uniform arc. The existing method is to roll the metal plate between rollers. Smaller-diameter rollers cannot directly make the metal plate reach the expected curvature, and it is necessary to repeatedly roll to increase the curvature of the metal plate. Moreover, during the rolling process, the curvature of the metal plate needs to be determined by measurement. Therefore, it is relatively troublesome to obtain a segment with a standard arc. Summary of the Invention

[0003] The purpose of this application is to provide an attached vibration segment die with a standard and fast forming.

[0004] To achieve the above object, this application provides an attached vibration segment die: including a base, a support table is fixedly connected to the base, the top of the support table has an arc-shaped table, a pair of side pressing mechanisms are also arranged on the base, respectively located at both ends of the arc of the arc-shaped table, and a pair of end pressing mechanisms are also arranged on the side of the support table, respectively located on both sides where the generatrix of the arc-shaped table is located. A segment body is suitable for being placed on the arc-shaped table. The side pressing mechanism is suitable for extruding the segment body into an arc same as that of the arc-shaped table, and the end pressing mechanism is suitable for keeping both sides of the segment body flat to avoid warping in the middle of the segment body.

[0005] As a preference, the side pressing mechanism includes a hydraulic cylinder fixedly connected to the base. The movable end of the hydraulic cylinder is fixedly connected to a positioning beam through a traction beam. A pressing arc plate is fixedly connected to the side of the positioning beam facing the arc-shaped table, which is suitable for pressing the segment body tightly on the arc-shaped table to form an arc consistent with that of the arc-shaped table.

[0006] As a preference, the positioning beam includes a limiting plate fixedly connected to the pressing arc plate. The upper edge of the limiting plate is fixedly connected to an upper bridge plate, the lower edge of the limiting plate is fixedly connected to a lower bridge plate, the traction beam is fixedly connected to the lower bridge plate, and a bridging plate is fixedly connected to the flat sides of the limiting plate, the lower bridge plate and the upper bridge plate to ensure the stability of the upper and lower bridge plates relative to the limiting plate.

[0007] As a preferred embodiment, the limit plate, lower bridge plate and upper bridge plate are all arc-shaped and parallel to the pressure arc plate. A reinforcing plate is fixedly connected between the lower bridge plate and the upper bridge plate. The reinforcing plate is located on the side of the limit plate facing away from the pressure arc plate and is fixedly connected to the limit plate, thereby further improving the structural stability of the lightweight positioning beam.

[0008] Preferably, there are several reinforcing plates on each positioning beam, and these reinforcing plates are arranged equidistantly along the curvature extension direction of the positioning beam to evenly disperse the force.

[0009] Preferably, the end pressure mechanism comprises a driver and a pressure claw, both of which are rotatably connected to the support platform, and the driver is suitable for driving the pressure claw to rotate relative to the arc platform, thereby achieving clamping and releasing actions on both sides of the tube body.

[0010] As a preferred embodiment, the pressure claw includes a pressure plate suitable for direct contact with the tube sheet body, the pressure plate has a load-bearing part on the side facing away from the arc-shaped platform, and the load-bearing part and the lower surface of the pressure plate have a swinging part; the side of the support platform has a lower articulated frame and an upper articulated frame, the driver includes a cylinder, the lower end of the cylinder is rotatably connected to the lower articulated frame, the upper movable end of the cylinder is fixedly connected with a force sleeve, the force sleeve is rotatably connected to the load-bearing part through a transmission shaft, and the swinging part is rotatably connected to the upper articulated frame through a limiting shaft, thereby ensuring the freedom of movement of each moving part.

[0011] As a preferred embodiment, a clearance groove is provided in the middle of the load-bearing part, which is suitable for fitting with the force-applying sleeve. A load-reducing groove is also provided on the support platform, so as to reduce consumables and lower deadweight while ensuring structural strength.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By designing a support platform with a standard curvature upper end surface, a side pressure mechanism is used to press the metal plate raw material of the segment onto the curved platform. When the metal plate is completely attached to the upper surface of the curved platform, it can become a segment with a standard curvature. The hydraulic cylinder can apply a reciprocating force similar to vibration to the metal plate through the pressure arc plate, which effectively improves the forming efficiency of the segment;

[0014] (2) By setting up an end pressure mechanism, the straightness of both sides of the metal plate can be ensured when the metal plate is bent, thereby effectively avoiding the warping of the middle part of the metal plate due to the force on both ends and no force in the middle. When the force claws are flipped open, the formed tube body can slide out from the side, so demolding is also more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0027] The terms "comprising" and "having" in the description and claims of the present application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0028] As Figure 1-8 shown, the attached vibrating segment mold includes a base 1 at the bottom. The base 1 is usually fixed to the ground or the frame by bolts to keep the entire mold equipment stable. A support table 2 is fixedly connected to the base 1. Above it is a workbench for forming vibrating segments. A weight-reducing groove 203 is also provided on the support table 2 to reduce consumables and self-weight on the premise of ensuring structural strength and stability, so as to achieve the lightweight of the entire mold. The top of the support table 2 has an arc-shaped table 204. The arc-shaped table 204 is a part of the side wall of a cylinder. Generally, the opposite sides of the arc of the arc-shaped table 204 are defined as end faces, and the opposite straight sides of the arc-shaped table 204 are defined as side faces. The segment body 5 is placed on the arc-shaped table 204. The segment body 5 is a flat steel plate in the formed part.

[0029] A pair of side pressing mechanisms 3 are also arranged on the base 1, respectively located at both ends of the arc of the arc-shaped table 204 and symmetrically arranged with respect to the support table 2. The side pressing mechanism 3 is used to squeeze the flat segment body 5 into the same arc as the arc-shaped table 204. The side pressing mechanism 3 specifically includes a hydraulic cylinder 301 fixedly connected to the base 1, which can generate a large force. The upward moving end of the hydraulic cylinder 301 is fixedly connected with a positioning beam 330 through a traction beam 302. The distance between the two positioning beams 330 is slightly larger than the width of the segment body 5, which can provide a good limiting effect on the segment body 5 and prevent the segment body 5 from moving on the arc-shaped table 204. The side of the positioning beam 330 facing the arc-shaped table 204 is fixedly connected with a pressing arc plate 304. The radian of the pressing arc plate 304 is the same as that of the arc-shaped table 204, which can press the segment body 5 on the arc-shaped table 204 and force the segment body 5 to bend into an arc. The positioning beam 330 includes a limiting plate 331 fixedly connected to the pressing arc plate 304. The limiting plate 331 contacts the end face of the segment body 5 that will generate a radian, playing a limiting role. The pressing arc plate 304 contacts the upper surface of the segment body 5, and then applies a squeezing force.

[0030] The upper edge of the limiting plate 331 is fixedly connected with an upper bridge plate 334, and the upper bridge plate 334 extends away from the pressing arc plate 304. The lower edge of the limiting plate 331 is fixedly connected with a lower bridge plate 333, and the extending direction of the lower bridge plate 333 is the same as that of the upper bridge plate 334. The traction beam 302 is directly fixedly connected with the lower bridge plate 333. The flat side faces of the limiting plate 331, the lower bridge plate 333 and the upper bridge plate 334 are jointly fixedly connected with a bridging plate 332 to ensure the distance between the lower bridge plate 333 and the upper bridge plate 334. The limiting plate 331, the lower bridge plate 333 and the upper bridge plate 334 are all arc-shaped and are all parallel to the pressing arc plate 304, or rather, the central angles of the radian coincide. A reinforcing plate 335 is also fixedly connected between the lower bridge plate 333 and the upper bridge plate 334. The reinforcing plate 335 is located on the side of the limiting plate 331 facing away from the pressing arc plate 304 and is fixedly connected with the limiting plate 331, further improving the connection strength between the upper bridge plate 334 and the lower bridge plate 333 and the limiting plate 331, so that the entire positioning beam 330 is not easily deformed when stressed. The number of reinforcing plates 335 on each positioning beam 330 is several, and these reinforcing plates 335 are arranged at equal intervals along the extending direction of the radian of the positioning beam 330, evenly dispersing the force. In fact, this is also for the consideration of lightweight design. While ensuring the structural strength and force stability of the positioning beam 330, it greatly reduces the consumption of materials and self-weight, making the hydraulic cylinder 301 consume less energy when operating.

[0031] A pair of end pressing mechanisms 4 are also provided on the side surface of the support table 2, respectively located on both sides of the busbar of the arc-shaped table 204. The two end pressing mechanisms 4 are also symmetric about the support table 2. The end pressing mechanism 4 is used to keep both sides of the segment body 5 flat. The specific structure of the end pressing mechanism 4 includes a driver 410 and a pressing claw 420. Both the driver 410 and the pressing claw 420 are rotatably connected to the support table 2. The driver 410 is used to drive the pressing claw 420 to rotate relative to the arc-shaped table 204, so as to realize the pressing and releasing actions on the segment body 5. The pressing claw 420 includes a pressing flat plate 422 that can be in direct contact with the segment body 5. The pressing flat plate 422 is straight and is consistent with the extending direction of both sides of the segment body 5. On the side of the pressing flat plate 422 facing away from the arc-shaped table 204, there is a load-bearing part 423. Usually, the load-bearing part 423 is parallel to the pressing flat plate 422. The lower surfaces of the load-bearing part 423 and the pressing flat plate 422 also have a swinging part 421, and the swinging part 421 is perpendicular to the pressing flat plate 422. The side surface of the support table 2 has a lower hinge bracket 201 and an upper hinge bracket 202. The upper hinge bracket 202 is located above the lower hinge bracket 201. The main body of the driver 410 is a cylinder 411. The lower end of the cylinder 411 is rotatably connected to the lower hinge bracket 201. The upper movable end of the cylinder 411 is fixedly connected with a force application sleeve 412. The force application sleeve 412 is rotatably connected to the load-bearing part 423 through a transmission shaft 403. A relief groove 424 is provided at the middle position of the load-bearing part 423, which just fits with the force application sleeve 412, making the matching structure more compact. The swinging part 421 is rotatably connected to the upper hinge bracket 202 through a limit shaft 404. The axes of the rotating pairs in the end pressing mechanism 4 are all parallel, ensuring the smoothness of the relative movement of the moving parts.

[0032] Working principle: In the initial state, the cylinder 411 contracts, the pressing claw 420 is lifted, and the pressing flat plate 422 is not in the arc extension direction of the arc-shaped table 204. The hydraulic cylinder 301 extends, and the pressing arc plate 304 moves upward away from the arc-shaped table 204. The two limiting plates 331 with larger longitudinal dimensions are located at both ends of the arc-shaped table 204. The flat segment body 5 original plate is placed on the arc-shaped table 204 and is constrained by the two limiting plates 331. The hydraulic cylinder 301 contracts, driving the pressing arc plate 304 to move downward until the pressing arc plate 304 contacts the segment body 5 and applies pressure to the segment body 5, causing it to bend and deform. Then the pressing arc plate 304 slightly lifts upward to reduce the pressure on the segment body 5. The cylinder 411 extends, driving the pressing claw 420 to swing towards the arc-shaped table 204. If the pressing flat plate 422 touches the side of the segment body 5 during the movement, it will push the segment body 5 to slide on the upper surface of the arc-shaped table 204 until both sides of the segment body 5 are completely within both sides of the arc-shaped table 204. Finally, both sides of the segment body 5 are pressed by the pressing flat plate 422 on the upper surface of the arc-shaped table 204, so that both sides of the segment body 5 can be kept straight, and the position of the segment body 5 relative to the arc-shaped table 204 will also be more stable. Start the hydraulic cylinder 301 again, driving the pressing arc plate 304 to repeatedly press down on the segment body 5 to generate a regular vibration pressure until the segment body 5 is completely attached to the arc-shaped table 204. At this time, the arc-shaped segment body 5 with good anti-vibration performance is formed. Finally, the cylinder 411 contracts, the pressing claw 420 returns to its original position, the hydraulic cylinder 301 extends, and the pressing arc plate 304 releases the extrusion pressure on the segment body 5, and then the formed segment body 5 can be pushed to slide off the arc-shaped table 204, and the next round of forming operation can be carried out.
