Abstract
Description
Technical Field
[0001] This utility model relates to the field of liner processing technology, and in particular to a limiting device for liner processing. Background Technology
[0002] Wear-resistant liners for mining are mainly used in hoisting equipment, mining equipment, mineral processing equipment, and crushing equipment. Traditional processing methods for high-strength wear-resistant plates involve hot working, which greatly affects the hardness of the plates and results in inconsistent product quality and high processing costs.
[0003] Using laser cutting and reaming equipment, mounting holes of predetermined shapes can be formed on the surface of steel plates through cold processing to meet the requirements of lining plates. Combining laser cutting and reaming equipment eliminates the need for workers to transport large steel plates, improving work efficiency. Furthermore, secondary positioning only requires positioning along the length conveying direction, further improving the overall efficiency of cold processing.
[0004] During cold processing, the steel plate needs to be fixed in place. Using traditional grippers requires fixing the steel plate at multiple points, which is inefficient. In addition, to prevent dust from laser cutting from spilling out, the laser cutting equipment is equipped with a sealed chamber. Using traditional clamping and limiting fixtures requires the operator to enter the sealed chamber for clamping and positioning. The internal fumes need to be vented before the positioning operation can be performed, which further reduces the overall processing efficiency. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a limiting device for liner processing. It eliminates the need for workers to enter the sealed chamber and wait for the negative pressure of the smoke and dust in the sealed chamber to be extracted, thereby further improving the clamping and limiting efficiency and the overall processing efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A limiting device for liner processing is installed at the passage opening between the machine tool and the sealing chamber. It includes two parallel limiting rods and a control block for driving the limiting rods to move horizontally. Two control blocks are symmetrically arranged. The side wall of each control block has a control surface that is inclined inward. The limiting rods are slidably connected to the control surfaces. A sealing device is also slidably connected to the side wall of the sealing chamber. The sealing device moves up and down in a vertical direction. The upper end of the control block is fixedly connected to the sealing device. During the descent of the sealing device, the control block is driven to descend synchronously. The descending control block squeezes the limiting rods and moves them inward to achieve clamping and limiting.
[0008] Preferably, the two control blocks form a set of control mechanisms, and two sets of control mechanisms and sealing devices are provided at intervals.
[0009] Preferably, the lower end of the sealing device is further provided with a sealing bladder, the sealing bladder having contractile elasticity, and also includes a pumping device for controlling the expansion of the sealing bladder.
[0010] Preferably, the air pumping device is a telescopic air rod, which is connected to the sealing bladder, and the telescopic air rod is disposed between the machine tool and the control block.
[0011] Preferably, the limiting rod has an inclined slope on the side near the control surface, the control surface has a control groove on its side wall, and a slider that extends into the control groove is fixed to the inclined side wall of the limiting rod.
[0012] Preferably, the sealing device includes a sealing base plate, a sealing side plate, and a lifting assembly, wherein the lifting assembly is disposed between the sealing base plate and the sealing chamber for controlling the lifting and moving of the sealing base plate and the sealing side plate.
[0013] Preferably, two sets of sealing side plates are provided inside and outside, and the vertical cross-section of the two sets of sealing side plates and the bottom sealing base plate is U-shaped.
[0014] Compared with the prior art, the advantages of this utility model are as follows:
[0015] Compared with traditional limiting fixtures, this device uses a combination of a limiting rod, a control block, and a sealing device. As the sealing device descends, it drives the control block down while simultaneously pushing the limiting rod inward, thus clamping and limiting the two plates inside and outside the sealing chamber. This eliminates the need for multi-point positioning with vises, improving clamping efficiency. Furthermore, the clamping and limiting on both the inner and outer sides are performed simultaneously, eliminating the need for personnel to enter the sealing chamber or wait for the negative pressure of the smoke and dust inside to be extracted, further improving clamping and limiting efficiency and overall processing efficiency.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] See attached document Figure 1 - Appendix Figure 8A cold-working method for high-strength wear-resistant lining plates is disclosed. The method utilizes a lining plate cold-working equipment, which includes a machine tool 200 supporting the plate 100, a laser cutting device 400, and a hole-reaming device. The laser cutting device 400 cuts the surface of the plate 100 to form countersunk holes 110 with the same upper and lower diameters. The hole-reaming device then reams the surface of the plate 100 to form mounting holes that meet the requirements. Specific details of the required mounting holes are provided in the appendix. Figure 1 .
[0028] A sealing chamber 300 is fitted around the outside of the laser cutting equipment 400. The sealing chamber 300 has openings 320 on both sides for the sheet metal 100 to pass through. Sealing devices 500 are installed at the lower ends of each opening 320. The sealing chamber 300 and sealing devices 500 seal the laser cutting equipment 400 inside (the sealing cover on top of the sealing chamber 300 has been removed for easier observation). Simultaneously, two openings 320 are provided on the front and rear sides of the sealing chamber 300 (along the length of the machine tool 200, i.e., the direction of the sheet metal 100's movement), allowing the sheet metal 100 to pass through sequentially for processing without the need for manual transfer, greatly improving processing efficiency. Furthermore, subsequent repositioning along the direction of the sheet metal 100's movement is only required, further improving the efficiency of cold processing of the sheet metal 100.
[0029] Specifically, the steps include the following:
[0030] S1. The plate 100 is conveyed to the surface of the processing machine tool 200 and faces the laser cutting equipment 400, and the plate 100 is fixed in a limited position. During the processing, the plate 100 is kept in a stable limited position to avoid the plate shaking from affecting the laser cutting.
[0031] S2. After the plate is fixed, the laser cutting equipment 400 is controlled to laser cut several countersunk holes 110 at predetermined positions on the plate surface. After the multiple countersunk holes 110 are processed, the limit fixation is removed. The countersunk holes 110 are connected vertically and have the same inner diameter. According to the processing needs, multiple countersunk holes 110 are formed in an array on the surface of the plate 100.
[0032] S3. The plate 100 processed in step S2 is transported along the processing machine tool 200 to the outside of the sealing chamber 300 opposite to the hole-expanding device. A traction device can be installed on the outside of the processing machine tool 200 or a transmission device can be set at the bottom to drive the plate 100 to move towards the outside of the sealing chamber 300, and finally move to the side of the hole-expanding device for hole-expanding processing. During the movement, the sealing device 500 is controlled to be raised and in the open state to ensure the normal movement of the plate.
[0033] The hole-expanding equipment shown in the figure is not included. Those skilled in the art can select the model and quantity as needed to meet the requirements for processing mounting holes, while ensuring the relative consistency of the processing rates before and after processing, so as to achieve continuous production of 100% of the board material and maximize the overall production efficiency of the equipment.
[0034] S4. After the plate 100 is aligned with the reaming device, the plate 100 is again positioned and fixed. Then, the upper end of the countersunk hole 110 is reamed using the reaming device to complete the cold working of the high-strength wear-resistant liner. The upper end of the countersunk hole 110 is reamed using the reaming device to form a frustum-shaped mounting hole. Specific processing dimensions are shown in the attached document. Figure 1 Alternatively, processing can be selected based on actual needs.
[0035] In summary, by setting up the above structure, the laser cutting equipment 400 inside can be sealed by the sealing chamber 300 and the sealing device 500, which can separate the laser cutting equipment 400 from the hole-reaming equipment. This avoids the large amount of smoke and dust generated during the laser cutting process from affecting the normal hole-reaming process on the outside, thus improving the processing environment and ensuring the normal operation of different processing steps. At the same time, there is no need for staff to transfer the sheet 100 between different workshops, which greatly improves the processing efficiency. Staff only need to perform secondary positioning along the direction of movement of the sheet 100, further improving the efficiency of cold working of the sheet 100.
[0036] Specifically, the plate 100 is fixed by a limiting device 600. The limiting device 600 includes limiting rods 610 located on both sides of the plate 100. Both limiting rods 610 are arranged along the length direction of the processing machine tool 200 and are parallel to each other. The limiting rods 610 on both sides can be adapted to the length direction of the plate 100. It also includes a control block 620 for controlling the horizontal position of the limiting rods 610. The control block 620 controls the two limiting rods 610 to move inward to complete the clamping and limiting of the plate 100.
[0037] During the clamping and limiting process, the limit rods 610 on both sides are controlled by the control block 620 to move inward to complete the clamping and limiting of the plate 100 on both sides. During the conveying of the plate 100, the limit rods 610 on both sides are controlled by the control block 620 to move outward to cancel the clamping and limiting of the plate 100 on both sides.
[0038] Specifically, the control block 620 includes an inclined control surface 621, and a limiting rod 610 is slidably connected to the control surface 621. During the descent of the control block 620, the limiting rod 610 is squeezed and moved inward. There are two control blocks 620, and the two control blocks 620 are symmetrically arranged around the vertical plane.
[0039] Through the upper and lower structure design, the horizontal drive of the limiting rod 610 can be achieved during the lifting and lowering of the drive control block 620. Here, the limiting rod 610 is located at the upper end of the processing machine tool 200 and is in a bearing state. Under the action of gravity, the limiting rod 610 is in a state of contact with the upper end of the processing machine tool 200. When the control block 620 moves downward, the inclined control surface 621 can squeeze the limiting rod 610 to move inward, completing the clamping and limiting of the plate 100. When the control block 620 moves upward, the control surface 621 is relatively offset outward. Here, the limiting rod 610 can descend under the action of gravity and abut against the upper end of the processing machine tool 200, and can automatically move to the outside, canceling the limiting of the edge of the plate 100.
[0040] It should be noted that the control surface 621 is set inward, and the vertical cross-section of the control surface 621 can be triangular to ensure normal movement control. At the same time, an elastic element can be installed between the control block 620 and the limit rod 610 to accelerate the reset of the limit rod 610 to the outside. During the lifting of the control block 620, the limit rod 610 can be pushed to move relative to the side and below to achieve rapid reset and release the restriction on the inner plate 100.
[0041] Furthermore, the control block 620 is fixedly connected to the sealing device 500 and moves synchronously with the sealing device 500. Through the above-mentioned structural arrangement, the control block 620 can be driven and controlled synchronously during the lifting and lowering of the sealing device 500. That is, during the sealing process of the sealing device 500 descending, the control block 620 is pushed down. After the control block 620 descends, it can squeeze the limiting rod 610 to move inward to complete the clamping and limiting of the plate 100. It can complete the clamping and limiting of the plate 100 on both sides while sealing on both sides, which further improves the processing efficiency of the plate 100.
[0042] Furthermore, two symmetrical control blocks 620 form a control mechanism. Two sets of control mechanisms are arranged at the front and rear, and the two sets of control mechanisms are fixedly connected to the corresponding sealing devices 500. Through the above structural design, the two sets of control mechanisms can be controlled by the sealing devices 500 on both sides. Compared with the traditional single-point control mechanism, the two sets of control mechanisms can push the limit rod 610 to move inward at two positions. The limit rod 610 can effectively push the plate 100 to the predetermined processing position, which is especially suitable for processing and positioning large-sized and heavy plates 100. It realizes fast and stable clamping and positioning, while avoiding stress concentration and damage, and improving the service life of the overall structure.
[0043] A sealing bladder 540 is also provided at the lower end of the sealing device 500, and a telescopic air rod 630 is provided between the lower end of the control block 620 and the processing machine tool 200. The telescopic air rod 630 is connected to the sealing bladder 540 through a pumping pipe.
[0044] By controlling the compression of the telescopic air rod 630, the gas inside the telescopic air rod 630 can be squeezed into the sealing bladder 540, and the sealing bladder 540 can be expanded. The sealing bladder 540 is set at the position where there is a sealing gap. The expanded sealing bladder 540 can enhance the sealing effect at the gap, prevent dust leakage generated in the sealing chamber 300, and further ensure the processing environment in the processing workshop.
[0045] Furthermore, through the above structural design, the sealing bladder 540 can be automatically controlled to expand during the descent of the sealing device 500, thereby achieving automatic sealing. During the descent of the sealing device 500, the gas inside the sealing bladder 540 can be automatically extracted, thereby achieving automatic contraction of the sealing bladder 540. This creates a larger opening 320 for the plate 100 to pass through, improving the overall sealing effect and increasing the efficiency of plate 100 transfer and conveying.
[0046] The sealing device 500 includes a sealing base plate 510 and sealing side plates 520 located on both sides of the upper end of the sealing base plate 510. The two sealing side plates 520 are sleeved on the outside of the sealing chamber 300 and are slidably connected to the sealing chamber 300. A lifting assembly 530 is also provided between the sealing chamber 300 and the sealing base plate 510 to control the lifting and moving of the sealing base plate 510.
[0047] The aforementioned lifting assembly 530 can be a combination of a hydraulic telescopic rod and a guide rod. By controlling the hydraulic telescopic rod to extend and retract, the extension and retraction control of the sealing base plate 510 and the sealing side plate 520 is achieved, thus realizing the sealing setting. The sealing side plates 520 on both sides can also play a guiding and limiting role, ensuring the stability of the sealing device 500 as a whole during movement. At the same time, the sealing side plates 520 on both sides and the sealing base plate 510 can form a U-shaped sealing area, further preventing dust leakage from the sealing chamber 300.
[0048] A negative pressure pipe 310 is provided on the side wall of the sealed chamber 300. The negative pressure pipe 310 is connected to a negative pressure device. During the laser cutting process, the dust in the sealed chamber 300 can be quickly extracted by negative pressure through the negative pressure pipe 310, so as to maintain the sealed chamber 300 in a relatively clean state and further prevent the dust from overflowing.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
