Description

Technical Field

[0001] This utility model relates to the field of iron drum weld flattening technology, specifically an iron drum body double-station weld flattening machine. Background Technology

[0002] The iron drum consists of a body and a bottom. The body can be made by rolling and processing sheet metal. After processing, a straight-line weld is reserved at the joint of the sheet metal in the body. A circumferential weld is reserved at the welding position between the bottom and the body. The weld is the weakest link in the iron drum structure. Its strength and sealing performance are crucial to the service life and safety of the iron drum. Flattening the weld can eliminate defects in the weld, such as porosity and slag inclusions, thereby improving the strength and sealing performance of the weld.

[0003] Currently used weld flattening machines are mainly used for flattening straight welds on drum bodies without bottoms. During flattening, the pressure rollers on the flattening machine roll on the outside of the straight weld on the outside of the drum body to flatten the weld. If the processed iron drum is a complete iron drum, this type of weld flattening machine is not conducive to flattening the circumferential weld on the basis of flattening the straight weld on the drum body. This leads to the need to transfer to another station to flatten the circumferential weld. It is not conducive to combining the flattening of straight welds and circumferential welds to improve the efficiency of weld flattening. Utility Model Content

[0004] The purpose of this invention is to provide a double-station weld flattening machine for iron drum bodies to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A double-station flattening machine for welding seams on iron drum bodies, including:

[0007] A base plate, on the top of which a control box is fixed;

[0008] The bracket is fixedly connected to the base plate. The bracket includes two L-shaped columns, one end of which is fixed to an L-shaped column.

[0009] The guide rail is fixed to the top of two L-shaped columns, and a movable seat slides inside the guide rail.

[0010] A flattening mechanism is fixedly connected to a movable base. The flattening mechanism includes a cylinder, a drive shaft that rotates at the output end of the cylinder, a motor that can drive the drive shaft to rotate that is fixed to the outside of the output end of the cylinder, and a flattening assembly that is fixed to the bottom end of the drive shaft.

[0011] The support base is fixed to the top of the two L-shaped columns.

[0012] A support mechanism is rotatably arranged on one side of a support base. The support mechanism includes a support shaft, a crossbeam fixed to one end of the support shaft, a support plate fixed to both ends of the crossbeam, an annular plate fixed between the two support plates, and two cylinders that can support and fix the iron barrel fixed to the outside of the crossbeam.

[0013] Furthermore, the bracket has a lead screw that is rotatably connected to the movable seat, and the control box has a motor for driving the lead screw to rotate.

[0014] Furthermore, a gear one is fixed to the outer side of the transmission shaft, and a gear two that meshes with the gear one is fixed to the outer side of the motor one.

[0015] Furthermore, an annular groove is provided on one side of the support base, and a support cylinder that is rotatably connected to the annular groove is fixed on the outer side of the support shaft.

[0016] Furthermore, the output end of the second cylinder is fixed with an arc-shaped plate, and a rubber sleeve is fixed to the outer side of the arc-shaped plate.

[0017] Furthermore, the flattening component includes:

[0018] An I-shaped seat is fixed to the bottom end of the drive shaft;

[0019] The connecting shaft is detachably inserted and fixed to the C-shaped base;

[0020] The flattening wheel is rotatably sleeved on the outside of the connecting shaft.

[0021] Furthermore, one end of the connecting shaft is provided with an insertion hole, and a pin is detachably inserted and fixed inside the insertion hole.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By attaching the iron drum to the outside of the support plate and the annular plate, the annular plate is supported below the annular weld. The output end of cylinder two extends, causing the two arc-shaped plates to support and fix the iron drum on the support shaft. The output end of cylinder one drives the flattening wheel on the flattening assembly to move down and abut against the annular weld. The motor three inside the control box drives the support shaft to rotate, causing the crossbeam to drive the iron drum to rotate around the support shaft as the axis. During the rotation of the iron drum, the flattening wheel rolls outside the annular weld, which facilitates flattening the annular weld on the iron drum.

[0024] 2. During the process of fixing the iron drum to the outside of the support shaft, the pallet is simultaneously positioned below the straight weld seam on the iron drum. Motor 1 drives the connecting shaft to rotate 90 degrees so that the plane of the flattening wheel is parallel to the straight weld seam on the iron drum. At this time, the support shaft no longer rotates with the iron drum. The output end of cylinder 1 extends again so that the flattening wheel abuts against the straight weld seam on the iron drum. Motor 2 drives the lead screw to rotate so that the movable seat connected to it rolls along the outside of the straight weld seam on the iron drum with the flattening wheel on the flattening mechanism, which facilitates flattening the straight weld seam on the iron drum. By changing the direction of the flattening wheel in conjunction with the support mechanism to drive the iron drum to rotate, it is convenient to switch the iron drum between the circumferential weld flattening station and the straight weld flattening station, which helps to improve the efficiency of flattening the iron drum weld seam.

Detailed Implementation

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1, please refer to Figure 1 - Figure 6 In this embodiment of the utility model, the double-station weld flattening machine for iron drum body includes a base plate 100, a control box 110 fixed to the top of the base plate 100, a bracket 200 fixed to the top of the base plate 100, the bracket 200 including two L-shaped columns 210, one end of which is fixed to an L-shaped column 220, and the top of the two L-shaped columns 210 is fixed to a guide rail 300. A movable seat 310 slides inside the guide rail 300, and a flattening mechanism 400 is provided inside the movable seat 310. The flattening mechanism 400 includes a cylinder 410 fixedly connected to the movable seat 310, and a transmission shaft 41 rotates at the output end of the cylinder 410. 1. A motor 420 capable of driving a drive shaft 411 to rotate is fixed to the outer side of the output end of cylinder 410. A flattening assembly 430 is fixed to the bottom end of the drive shaft 411. A support base 500 is fixed to the top of the two L-shaped columns 220. A support mechanism 600 is provided on one side of the support base 500. The support mechanism 600 includes a support shaft 610 rotatably connected to the support base 500. A crossbeam 620 is fixed to one end of the support shaft 610. A support plate 630 is fixed to both ends of the crossbeam 620. An annular plate 631 is fixed between the two support plates 630. Two cylinders 640 capable of supporting and fixing iron barrels are fixed to the outer side of the crossbeam 620.

[0034] Specifically, by attaching the iron drum to the outside of the support plate 630 and the annular plate 631 of the support mechanism 600, the output end of the cylinder 410 drives the flattening roller 433 to abut against the outside of the annular weld seam of the iron drum, and the annular plate 631 supports it on the inside of the annular weld seam. At the same time, the support mechanism 600 drives the iron drum to rotate, so that the flattening roller 433 rolls around the annular weld seam, which facilitates the automatic flattening of the annular weld seam on the iron drum by the flattening roller 433. The motor 420 drives the transmission shaft 411 to rotate the flattening roller 433 on the flattening mechanism 400 by 90 degrees. At the same time, cylinder 410 drives the flattening roller 433 to move down, so that the flattening roller 433 abuts against the outside of the straight weld seam of the iron drum. With the support plate 630 supporting the inside of the circumferential weld seam, the moving seat 310 carries the flattening mechanism 400 to move linearly along the guide rail 300, so that the flattening roller 433 can automatically flatten the straight weld seam on the iron drum. Thus, by changing the flattening direction of the flattening roller 433 and cooperating with the support mechanism 600 to drive the iron drum to rotate, the iron drum can be flattened at different work positions for both circumferential and straight weld seams, which is beneficial to the efficiency of flattening the weld seam of the iron drum.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, a lead screw 320 is rotatably connected to the movable seat 310 inside the guide rail 300. A second motor for driving the lead screw 320 to rotate is fixed inside the control box 110. The second motor drives the lead screw 320 to rotate in both directions, which in turn drives the movable seat 310 connected to the lead screw 320 to slide back and forth on the guide rail 300. The back and forth sliding of the movable seat 310 can drive the flattening mechanism 400 to flatten the straight weld seam on the outside of the iron barrel.

[0036] like Figure 3 As shown, in this embodiment, a connecting column 520 is fixed to the top of the support base 500. The connecting column 520 is fixedly connected to the guide rail 300, so that the support base 500 can stably rotate on the bracket 200 to support the support mechanism 600.

[0037] like Figure 1 and Figure 4 As shown, in this embodiment, a gear 1 is fixed to the outside of the transmission shaft 411, and a gear 2 that meshes with the gear 1 is fixed to the outside of the motor 420. The output end of the motor 420 drives the gear 2 to rotate, causing the gear 1 to drive the transmission shaft 411 to rotate. The transmission shaft 411 drives the C-shaped seat 431 to rotate with the flattening wheel 433, thereby adjusting the flattening wheel 433 to align with the straight weld seam position 710 or the circumferential weld seam position 720.

[0038] like Figure 3 and Figure 5As shown, in this embodiment, an annular groove 510 is provided on one side of the support base 500, and a support cylinder 611 rotatably connected to the annular groove 510 is fixed on the outer side of the support shaft 610. During the rotation of the support shaft 610, the support cylinder 611 on the outer side of the support shaft 610 will rotate inside the annular groove 510. At the same time, one end of the support cylinder 611 is fixed to the support shaft 610 by a plurality of evenly arranged reinforcing ribs, so that the support shaft 610 stably carries the support mechanism 600 to rotate on the support base 500.

[0039] like Figure 2 and Figure 5 As shown, in this embodiment, an arc-shaped plate 641 is fixed to the output end of cylinder 640. A rubber sleeve is fixed to the outer side of the arc-shaped plate 641. When it is necessary to support and fix the iron bucket on the outside of the support plate 630, the output end of cylinder 640 extends to move the arc-shaped plate 641 towards the inside of the iron bucket. This allows the two arc-shaped plates 641, which move away from each other, to support and fix the iron bucket on the support mechanism 600. The support mechanism 600 remains stationary to support and fix the iron bucket, which facilitates the flattening mechanism 400 to flatten the iron bucket with a straight weld. The support mechanism 600 rotates with the iron bucket, which facilitates the flattening mechanism 400 to flatten the iron bucket with a circumferential weld. The cross-section of the support plate 630 is arc-shaped, which is convenient to match the arc shape of the inner wall of the iron bucket.

[0040] like Figure 6 As shown, in this embodiment, the flattening assembly 430 includes a C-shaped seat 431 fixedly connected to the drive shaft 411. A connecting shaft 432 is detachably inserted and fixed inside the C-shaped seat 431. A flattening wheel 433 is rotatably mounted on the outside of the connecting shaft 432 via a bearing. After the flattening wheel 433 rotates on the connecting shaft 432 and comes into contact with the weld, it can roll and flatten the weld at the weld position.

[0041] In this embodiment, the existing flattening roller 433 is mainly cylindrical and has a three-segment arc (the roller is designed with a concave arc in the middle and convex arcs on both sides). The required flattening roller 433 can be replaced on the C-shaped seat 431 as needed.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, a motor 3 for driving the support shaft 610 to rotate is fixed inside the control housing 110. By driving the support shaft 610 to rotate through the motor 3, the support mechanism 600 on the outside of the support shaft 610 can rotate with the iron bucket.

[0043] In this embodiment, a prior art electric slip ring component can be installed on the outside of the support shaft 610 to provide power to the cylinder 640 on the rotating support shaft 610. The specific electric slip ring combined with the wire to transmit electrical energy is prior art and will not be described in detail here.

[0044] Example 2, based on Example 1, involves disassembling and replacing the worn flattening wheel 433.

[0045] like Figure 5 As shown, in this embodiment, one end of the connecting shaft 432 is provided with an insertion hole, and a pin 4321 is detachably inserted and fixed inside the insertion hole. When replacing the flattening roller 433, the pin 4321 at one end of the connecting shaft 432 is pulled out, the connecting shaft 432 is removed from the C-shaped seat 431, the flattening roller 433 is readjusted on the connecting shaft 432, and the connecting shaft 432 is inserted and installed inside the C-shaped seat 431. Finally, the pin 4321 is pinned.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
