Description

Technical Field

[0001] The invention relates to the technical field of elevator counterweight block forming and processing, and in particular to a fixed-length rolling, blanking and integrated forming and processing technology for an elevator steel plate counterweight block. Background Art

[0002] The function of the counterweight is to balance the car, that is, there is a traction rope connecting the car and the counterweight frame. The traction rope is driven by the friction between the traction wheel on the roof and the traction rope to drive the car up and down. It is usually made of cast iron and cut by flame cutting, plasma cutting or high-power laser. Then an angle grinder is used to grind the burrs on the edge and the subsequent plate processing;

[0003] However, due to the unclear source of raw materials, uneven materials, and the fact that most plate processing uses hot cutting, edge burrs are easily generated, resulting in the problem of flatness of the counterweight after processing. For this reason, the steel mill rolls the flat steel to a certain size, and performs quality control and assurance on the raw material material. The reference standard: the steel billet standard adopts the Q235A grade in the national standard (GB / t700-2006), and the hot-rolled flat steel after forming refers to the standard (GB / T 704-1988). The flat steel is punched to a certain size, and the daily production capacity is increased by continuous processing. At the same time, waste generation is reduced and the overall power consumption of the equipment is reduced. The counterweight forming process is more environmentally friendly and safer. In addition, considering the material and size of the counterweight, after the punching is completed, the operator needs to manually or the robot arm needs to automatically clamp and unload the material due to the mold limit. The unloading efficiency is low, which affects the overall processing progress of the counterweight.

[0004] Therefore, we propose an integrated forming process of fixed-length rolling, blanking and cutting of elevator steel plate counterweight. Summary of the invention

[0005] The object of the present invention is to provide a fixed-length rolling, blanking and integrated forming processing technology for an elevator steel plate counterweight block to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a fixed-length rolling and blanking integrated forming process for an elevator steel plate counterweight block, comprising the following steps:

[0007] Flat steel forming: A three-stage continuous pusher heating furnace is used, with a cantilever roller in the furnace. The raw material steel types include continuous casting billet, ordinary carbon, high-quality carbon, low alloy or alloy steel.

[0008] The preheating temperature of raw steel is lower than 900℃, the subsequent heating temperature is controlled at 1000-1250℃, and the stable heating temperature in the furnace is controlled at 1150-1280℃;

[0009] When the furnace is shut down normally, close the burners, air intake and exhaust valves one by one from the preheating section, heating section to the soaking section. Do not pour water into the furnace. The furnace doors on both sides of the furnace can be opened only when the furnace temperature is below 150℃.

[0010] The billet is rolled out, the height of the crossbeam is determined by the bottom of the rolling groove, and it is locked with bolts and must not be loosened. It is strictly forbidden to weld the crossbeam to the frame. The crossbeam of the rolling mill should be kept horizontal. The width of the inlet guide plate should be greater than the width of the rolled piece and should be aligned with the hole type. The width of the outlet guide plate should not be less than the maximum width of the hole type. The guide plate bolts must be tightened. The guard plate is required to be installed smoothly. The guard plate should be consistent with the bottom of the rolling groove. The contact tip should be 10-15mm lower than the rolling groove. The contact arc length is not less than 25-30mm. The starting rolling temperature is 1150-1200℃, and the final rolling temperature should not be lower than 850℃;

[0011] The hot saw shears cut the rolled steel into uniform sections, and a cooling bed is set up to cool the steel after section cutting. Then the straightening machine is used to straighten the steel to complete the flat steel forming;

[0012] Flat steel conveying: The conveying equipment includes a placing rack 1 and a placing rack 2. A conveyor 1, a conveyor assembly 1 and a clamping assembly 1 are installed on the placing rack 1, and a conveyor 2, a conveyor assembly 2 and a clamping assembly 2 are installed on the placing rack 2. The crane arm on one side of the conveyor moves the flat steels one by one to the surface of the conveyor 1 on the placing rack 1, and the clamping assembly 1 on the conveyor assembly 1 is used to move the flat steels to the conveyor 2 on the placing rack 2 side, and the clamping assembly 2 on the conveyor assembly 2 is coordinated with the movement to move a single piece of flat steel to the hydraulic punching table;

[0013] Flat steel blanking: Flat steel processing is carried out using blanking equipment.

[0014] Among them, the punching equipment includes a hydraulic punching table and a placing table, a punching assembly is installed on the placing table, and the punching assembly includes a die table, a rotating arm, a punching block and a pressure plate. The top of the placing table is slidably connected to the die table, and the bottom of the die table is symmetrically provided with a punching block in an integrated manner. The bottom of the punching block is slidably connected to a pressure plate, and a support column on the pressure plate passes through one side of the bottom of the die table and is sleeved with a spring. An abutment column is fixed to one side of the bottom of the die table by spot welding, and the side wall of the die table is movably connected to a rotating arm.

[0015] Furthermore, a mold platform 2 is installed on the top of the placement table, and waste holes are evenly and symmetrically opened on the top of the mold platform 2. A paint touch-up box is installed on one side of the hydraulic punching table. A channel is opened on the top of the placement table and on the side of the mold platform 2, and one side of the channel is connected to the paint touch-up box.

[0016] Furthermore, conical blocks are slidably connected on both sides of the mold platform, and two springs are sleeved on the sides of the conical blocks. A pull rod is symmetrically fixed on one side of the conical block. Grooves are symmetrically opened on the top of the placement table, and a limiting block is slidably connected in the groove, and one end of the pull rod is fixed to the bottom of the limiting block.

[0017] Furthermore, the top of the paint touch-up box is rotatably connected to a rotary arm via a bearing, one side of the rotary arm is movably connected to a second rotary arm, and the other side of the rotary arm is slidably connected to the first rotary arm.

[0018] Furthermore, a push rod is slidably connected to the top of the mold platform 2, one end of the push rod is rotatably connected to a hook block, and one end of the rotating arm 2 is movably connected to the hook block.

[0019] Wherein, the conveying equipment also includes a storage shell and a lifting component. The storage shell is symmetrically installed on the storage rack, and the lifting component is installed on the bottom of the storage shell.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the elevator counterweight is directly obtained by punching the rolled flat steel to a predetermined size, which can continuously process materials, and the counterweight preparation speed is fast, and the daily production capacity is improved. At the same time, the waste generated in the plate processing process is reduced, the utilization rate of the plate is improved, and the typesetting process is reduced. The two ends of the plate are directly processed, and the processing technology is simplified. Compared with cutting the plate, the energy loss is reduced, which is more environmentally friendly and safer. At the same time, the cumbersome process of secondary slag removal after plasma and flame cutting is avoided, and the size is more accurate and the flatness is higher;

[0022] 2. In the present invention, by installing the storage shell on the placement rack 1, the flat steel billets are placed one by one along with the lifting arm. The flat steel billet loading and blanking efficiency are not equal, which may easily lead to the retention of flat steel billets on the conveyor 2, affecting the flat steel billet loading of the clamping assembly 2. The storage shell temporarily stores the flat steel billets, completes the storage of the flat steel billets when the loading rate is fast, and actively feeds the billets when the loading rate is slow, so as to always keep the flat steel billet blanking assembly working efficiently;

[0023] 3. In the present invention, the abutment column is driven to contact the conical block through the movement of the die table one, and the conical block that is pressed downward drives the limit block through the pull rod to extrude and limit the flat steel billet placed on the die table two, so as to correct the position of the flat steel billet and avoid the problem of reduced precision of the counterweight block caused by direct punching. At the same time, as the entire die table one rises, the swing arm one drags the swing arm to rotate while the swing arm two moves. The push rod connected to the swing arm two drives the hook block to contact the edge of the flat steel billet and pull the flat steel billet to move until it moves into the channel, completing the automatic unloading of the flat steel billet after punching. Compared with manual collection or clamping by a robot arm, unloading of the counterweight block is simpler and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-9 , the present invention provides a technical solution:

[0036] Example 1: Figure 1 and Figure 2 As shown, the present invention adopts the method of rolling and cutting the flat steel to a certain size to directly obtain the elevator counterweight block, which can continuously process the materials, the counterweight block preparation speed is fast, the single-day production capacity is improved, and the waste generated in the plate processing process is reduced. The utilization rate of the plate can be increased from the original 73.2% to 85.5%, and the typesetting process is reduced, the two ends of the plate are directly processed, the processing technology is simplified, the energy loss is reduced, and it is more environmentally friendly and safer.

[0037] Among them, the power of plasma cutting machine is 15KW, and the power of this hydraulic blanking equipment is 8KW, which avoids the cumbersome process of secondary slag removal after plasma and flame cutting, and has more accurate size and higher flatness. When obtaining flat steel, the billet is first rolled, followed by slab finishing, and then cut to size, and finally stamped into shape;

[0038] like Figure 3 As shown, the entire sheared and corrected flat steel billet is packed and uniformly placed on the side of the conveyor 7, and is moved to the conveyor 7 one by one by using a crane arm. At the same time, the conveying assembly 3 located on the placement rack 2 starts to work, wherein the conveying assembly 3 is composed of a slider, a slide rail and a screw rod. The screw rod is driven by a motor to rotate and control the left and right and up and down movements of the sliders on both sides, so that the clamping assembly 4 located on the slider side can clamp the flat steel billet and move it;

[0039] A placing rack 2 8 is also installed behind the placing rack 1 2, and a conveying assembly 2 9 with the same working principle as the conveying assembly 1 3 is installed on the placing rack 2 8. Similarly, the clamping assembly 2 10 on the conveying assembly 2 9 can clamp the flat steel billet on the conveyor 2 11 and move it to the hydraulic punching table 1 to deal with the problem that the punching rate does not match the raw material feeding rate;

[0040] Considering that the loading rate of the flat steel billet is greater than the blanking rate, part of the flat steel billet is retained on the conveyor 7, affecting the gripping of the clamping component 2 10. For this reason, a residual material placement structure is designed on the entire placement rack 2. By adding a storage shell 5 and a lifting component 6, and providing a pad that can move up and down in the storage shell 5, when placing the flat steel billet, the clamping component 4 can first store the excess flat steel billet in the storage shell 5, and cooperate with the lowering of the pad in the storage shell 5 to realize the pre-storage operation of the residual flat steel billet on the conveyor 7, thereby avoiding the accumulation and retention of the flat steel billet on the conveyor 2 11;

[0041] Similarly, when the efficiency of placing the flat steel billet is reduced, in order to prevent the impact on the work of the punching mechanism, the motor drives the gear rod to move, pushes the pad inside the storage shell 5 to rise, and moves the remaining material to the shell mouth of the storage shell 5. At this time, the clamping assembly directly obtains the flat steel billet from the storage shell 5 to ensure that the subsequent punching equipment continues to work.

[0042] Embodiment 2: Considering the special blanking position of the counterweight block and the relatively thick plate, the normal manual blanking is difficult and risky. Therefore, by adding parts to the blanking assembly 12, the counterweight block blanking is automatically completed with the hydraulic lifting activity of the mold, which has a high degree of automation;

[0043] like Figure 4 and Figure 5 As shown, after the clamping assembly 10 moves the flat steel blank to the placement table 13 on the top of the hydraulic punching table 1, the die table 14 installed in advance on the top of the placement table 13 is adapted to the punched flat steel blank, that is, the waste hole 15 on the die table 14 is opened at the position that coincides with the diagonal edges of the flat steel blank, as shown in FIG. Figure 7 As shown, the descending die table 121 drives the punching block 123 to descend and contact the four corners of the flat steel billet;

[0044] A pressing plate 124 is also slidably connected to the bottom of the punching block 123. The weight of the pressing plate 124 and the push of the spring 125 on the die table 121 are used to first press the flat steel billet to prevent the flat steel billet from moving during the punching process of the punching block 123, thereby affecting the punching accuracy of the counterweight block.

[0045] Similarly, when placing the flat steel blank on the die table 14, the clamping assembly 10 is directly placed, and the flat steel blank will still have a certain probability of deviation, which affects the positioning of the subsequent punching block 123. Figure 8 As shown, a slot is provided on one side of the entire placement platform 13, and a conical block 16 is slidably connected in the slot, with the cut surface of the conical block 16 facing upward;

[0046] Similarly, a limit block 19 is symmetrically slidably connected in the groove at the top of the die table 121. The limit block 19 is customized in size according to the flat steel blank to be punched, and one end of the pull rod 18 on the conical block 16 is connected to the limit block 19. During the descent of the die table 121, the abutment column 126 installed on one side thereof first contacts the conical block 16, squeezes the conical block 16 to move to one side, and at the same time drags the limit block 19 to contact the flat steel blank on the die table 2 14. When the cross section of the limit block 19 abuts against the corner of the rectangular flat steel blank, the flat steel blank is driven to reset, and the reset work is completed before the punching block 123 contacts the flat steel blank, thus avoiding the problem of reduced punching accuracy caused by the deviation of the flat steel blank placement;

[0047] Accompanying the flat steel billet being punched on the die table 2 14, as Figure 5 and Figure 6As shown, when the entire mold platform 121 moves downward, the installed rotating arm 122 pushes down the rotating arm 22 installed on the top of the touch-up paint box 21, and the rotation of the rotating arm 22 pushes the rotating arm 23 to move toward the mold platform 2 14, as shown in FIG. Fig. 9 As shown, a push rod 24 is slidably connected at the end of the second rotating arm 23 and located on the second die table 14;

[0048] A hook block 25 that can only rotate on one side is installed on the side of the push rod 24. As the rotary arm 22 rotates, the second rotary arm 23 pushes the push rod 24 to contact the flat steel blank placed on the die table 14. At this time, the end hook block 25 rotates inward and gradually drives the push rod 24 to move on the top of the flat steel blank until the hook block 25 moves to the other side of the flat steel blank and then expands vertically with its own gravity. Then the entire pressing plate 124 contacts the flat steel blank, and finally the blanking block 123 punches.

[0049] Looking back at the entire flat steel blank blanking process, after the die table 121 descends, it drives the abutment column 126 to first contact the conical block 16, and at the same time, the rotating arm 122 contacts the rotary arm 22, gradually pressing down the rotary arm 22 to rotate, and then the limit block 19 moves to complete the flat steel blank placement position locking, and at the same time, the push rod 24 completes the top covering of the flat steel blank, and then the pressing plate 124 is pressed down and the blanking block 123 contacts the flat steel blank;

[0050] After the punching is completed, the punching block 123 and the pressure plate 124 are separated from the flat steel billet. At this time, the bottom contact column 126 of the rising die table 121 begins to contact the cut surface of the conical block 16, and the entire limit block 19 begins to move to the right and separate from the flat steel billet. At the same time, the entire push rod 24 begins to pull backward after the rotating arm 23 rotates in the opposite direction. At this time, the hook block 25 just contacts the edge of the flat steel billet, driving the entire flat steel billet to slide on the die table 2 14;

[0051] Due to the particularity of the blanking position of the flat steel billet, the flat steel billet with the corners blanked off just gives the limit block 19 a reset space, so that the hook block 25 will not be blocked at the first time when it pulls the flat steel billet to move synchronously. Then, when the limit block 19 breaks away from the lateral movement trajectory of the flat steel billet, the hook block 25 on the push rod 24 drives the flat steel billet to move into the channel 20 on the placement table 13, such as Figure 8 As shown, the channel 20 is connected to the interior of the touch-up paint box 21, and the punching counterweights stacked in the touch-up paint box 21 start the subsequent corner touch-up paint operation. At this time, the clamping component 2 10 immediately drives the new flat steel billet to move to the die table 2 14, and repeats the punching operation. There is no need for personnel to participate in the loading and unloading of the flat steel billet throughout the process, and the degree of automation is high, which improves the forming efficiency of the counterweights.

[0052] The working process and principle of the present invention are as follows:

[0053] The continuous casting billet, ordinary carbon, high carbon, low alloy or alloy steel is sent into the heating furnace for heating, and then the billet is rolled out of the furnace, and then the rolled steel is cut into uniform sections by hot saw shearing, and a cooling bed is set to cool the steel after section cutting, and then the steel is straightened by a straightening machine to complete the flat steel forming;

[0054] The flat steel blank is moved to the conveyor 1 by the crane arm, and the clamping assembly 14 on the conveying assembly 13 works, and then the flat steel blank is moved to the conveyor 2, and the clamping assembly 10 on the conveying assembly 29 is used to move the flat steel blank to the fixed position on the die table 2 14, and the die table 121 is descended. After the die table 121 descends, the abutment column 126 is driven to contact the conical block 16 first, and the rotating arm 122 contacts the rotary arm 22, and the rotary arm 22 is gradually pressed down to rotate, and then the limit block 19 moves to complete the locking of the flat steel blank placement position, and at the same time, the push rod 24 completes the top covering of the flat steel blank, and then the pressing plate 124 is pressed down and the punching block 123 contacts the flat steel blank;

[0055] After the punching is completed, the punching block 123 and the pressure plate 124 are separated from the counterweight block. At this time, the abutment column 126 at the bottom of the rising die table 121 begins to contact the cross-section of the conical block 16. With the push of the spring 2 17, the entire limit block 19 begins to separate from the counterweight block limit to the right. At the same time, the entire push rod 24 begins to pull backward after the rotating arm 23 rotates in the opposite direction. At this time, the hook block 25 just contacts the edge of the counterweight block, driving the entire counterweight block to slide on the die table 2 14. The hook block 25 on the push rod 24 drives the counterweight block to move to the channel 20 on the placement table 13 to perform the punching and corner touch-up operation.
