[0012] Based on the above technical solution, a method for using an emergency stop production device includes the following steps: Step 1: Control the vertical push-pull mechanism to lift the upper lifting seat, the middle lifting seat and the lower lifting seat, and then control the horizontal push-pull mechanism to move the two sliding seats away from each other and move to a suitable position, and then stack two rectangular hard plates (such as steel plates) whose front and rear spacing is consistent with the front and rear ends of the support platform and the left and right spacing is consistent with the left and right ends of the accommodating groove and place them horizontally on the top of the support platform, and then place two square tube profiles (such as aluminum alloy square tubes) that are easy to cold roll in the discharge grooves of the front and rear parts of the two sliding seats, so that the left and right parts of the square tube profile match the discharge groove, and the length is shorter than the maximum spacing of the discharge groove in which it is located.
[0013] Step 2: Control the vertical push-pull mechanism to move the lower lifting seat downward, so as to use the lower groove to cold-roll the square tube profile, so that it gradually becomes a "U" shape, and insert it into the side groove for shaping to form a "U"-shaped frame.
[0014] Step 3: After or at the same time as step 2, control the vertical push-pull mechanism to move the middle lifting seat downward, and control the drilling rig to rotate at the same time, so that the drill bit of the drilling rig can be used to drill holes in the "U"-shaped frame and the two hard plates through the through holes.

[0016] Step 5: After or at the same time as step 4, control the movement of the lateral push-pull mechanism to make the two sliding seats approach each other. When the adjacent ends of the two sliding seats are flush with the side walls of the side grooves, it should be ensured that the top of the upper lifting seat is not higher than the bottom of the sliding seat. Then continue to move to bend the middle of the upper part of the "U"-shaped frame to form a non-closed frame with a gap on the upper part.
[0017] Step 6: Control the lateral push-pull mechanism to move the two sliding seats away from each other to a suitable position, and control the vertical push-pull mechanism to lift the upper lifting seat, the middle lifting seat and the lower lifting seat until the non-closed frame is disengaged from the side groove, and then the two non-closed frames are disengaged from the upper lifting seat, the middle lifting seat and the lower lifting seat from the front and rear directions respectively, and then reinsert into the side groove.
[0018] Step 7: Control the vertical push-pull mechanism to move the lower lifting seat downward until the top of the lower groove contacts the upper part of the non-closed jig.
[0019] Step 8: Control the vertical push-pull mechanism to move the middle lifting seat downward, and control the drilling rig to rotate at the same time, so that the drill bit of the drilling rig can be used to drill holes in the upper part of the non-closed jig through the through hole.
[0020] Step 9: Control the horizontal push-pull mechanism to move the two sliding seats away from each other to a suitable position, control the vertical push-pull mechanism to lift the upper lifting seat, the middle lifting seat and the lower lifting seat, and then disengage the non-closed frame from the side groove, and then pull out the two hard plates. Bolts and nuts can be used to assemble the non-closed frame and the hard plate to form an emergency stop frame.
[0021] Compared with the prior art, the present invention has the following advantages: the present invention controls the horizontal push-pull mechanism to drive the sliding seat to slide left and right, and controls the vertical push-pull mechanism to drive the upper lifting seat, the middle lifting seat and the lower lifting seat to slide up and down, so as to realize cold rolling of square tube profiles to form "U"-shaped frames and non-closed frames in sequence, and utilizes a drilling rig that moves up and down synchronously with the middle lifting seat to punch holes in the "U"-shaped frame, the non-closed frame and the hard plate material, so as to facilitate the use of bolts and nuts to fasten the non-closed frame and the hard plate material to assemble into an emergency stop frame, the production steps are simple, clear and coherent, and there is no need for complex operations such as welding and repeated cutting, so the production cost is lower and the efficiency is higher.
[0022] When assembling the emergency stop frame, the lower driving push rod can be controlled to retract first. At this time, the insertion rod is inserted into the bottom of the through hole of the support platform, and then the screw portion of the hexagonal bolt is inserted into the through hole of the support platform with the screw portion facing upward. The circumferential position of the hexagonal bolt can be limited. Then, a hard plate is placed on the support platform, and then the non-closed frame is reinstalled into the side groove, so that the screw portion of the hexagonal bolt can be inserted into the holes of the hard plate and the non-closed frame. Then, the hexagonal nut is installed, and the hard plate and the bottom of the non-closed frame can be conveniently fastened together, thereby improving assembly efficiency.

[0031] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] like Figure 1-Figure 7 As shown, an emergency stop frame production device comprises a support frame 1, wherein the left and right parts of the support frame 1 are each slidably connected to a sliding seat 2, the two sliding seats 2 are symmetrically arranged compared to the support frame 1, and the front and rear parts of the top are each provided with a discharge groove 3 along the left and right direction, the support frame 1 is slidably connected to an upper lifting seat 4, a middle lifting seat 5 and a lower lifting seat 6 from top to bottom, the front and rear parts of the top of the upper lifting seat 4 are each provided with an upper groove 7 penetrating along the left and right direction, the front and rear parts of the bottom end of the lower lifting seat 6 are each provided with a lower groove 8 penetrating along the left and right direction, the bottom of the support frame 1 is provided with a receiving groove 9 for accommodating the upper lifting seat 4, the middle lifting seat 5 and the lower lifting seat 6 to enter and exit, the left and right ends of the receiving groove 9 are each provided with two side grooves 10 penetrating upward, the discharge groove 3, the upper groove 7. The lower groove 8 and the side groove 10 correspond to each other in the front plane. Two vertical drills 11 are fixed to the front and rear parts of the middle lifting seat 5. The drill rig 11 is externally connected to a controller and a power supply. The external controller is used to control the speed and start and stop of the drill rig 11. The controller is a known prior art, such as a single-chip microcomputer and a control circuit. The drill rig 11 at the front and rear parts of the middle lifting seat 5 corresponds to the two lower grooves 8 up and down. A horizontal support platform 12 is provided in the accommodating groove 9. The front and rear parts of the lower lifting seat 6 and the support platform 12 are respectively penetrated by through holes 13 up and down corresponding to the drill rods of the drill rig 11. A horizontal push-pull mechanism is installed between the sliding seat 2 and the support frame 1, and a vertical push-pull mechanism is installed between the upper lifting seat 4, the middle lifting seat 5, the lower lifting seat 6 and the support frame 1.
[0033] The discharge groove 3 horizontally penetrates the adjacent parts of the two sliding seats 2, and each of the discharge grooves 3 is respectively connected with a horizontal No. 1 polished rod 16 for left and right sliding. A vertical clamp 17 is fixed to the axial end of the No. 1 polished rod 16 near the horizontal penetration of the discharge groove 3. The clamp 17 is gap-inserted with the discharge groove 3, and each of the clamps 17 and the discharge groove 3 in which it is located is jointly fixed with a horizontal No. 1 compression spring 18. The No. 1 compression spring 18 is gap-inserted with the No. 1 polished rod 16, and the clamp 17 has a tendency to move toward the horizontal penetration of the discharge groove 3 under the elastic repulsive force of the No. 1 compression spring 18.
[0034] When the square tube profile 36 is placed in the discharge groove 3, the elastic repulsive force of the No. 1 compression spring 18 can be used to squeeze the clamp 17 on the square tube profile 36, so that the square tube profile 36 can be set in the center compared to the support frame 1, that is, the square tube profile 36 can be symmetrical on the left and right after cold rolling, so that the force is more uniform, and at the same time, the normal drilling by the drilling rig 11 is guaranteed at a later time.
[0035] An upper wedge-shaped guide block 19 is fixed to each of the front and rear ends of the lower lifting seat 6, and two lower wedge-shaped guide blocks 20 are fixed to each of the front and rear ends of the support platform 12. The upper wedge-shaped guide block 19 is inclined downward and expanded, and the lower wedge-shaped guide block 20 is inclined upward and expanded. The two lower wedge-shaped guide blocks 20 at the front and rear ends of the support platform 12 are arranged in the left and right parts of the support platform 12, and a gap is left between the lower wedge-shaped guide blocks 20 on the left and right parts of the support platform 12 to accommodate the insertion of the upper wedge-shaped guide block 19. The front and rear end surfaces of the support platform 12 are aligned with the front and rear end surfaces of the lower lifting seat 6.
[0036] Furthermore, the upper wedge-shaped guide block 19 and the lower wedge-shaped guide block 20 can guide the two hard plates 37 stacked in parallel so that they are centered front and back, thereby reducing accidental movement of the hard plates 37 and ensuring the accuracy of the drilling position when drilling with the drill rig 11.
[0037] The vertical push-pull mechanism includes an upper driving push rod 21, a connecting piece, and a tension spring 23. A vertical upper driving push rod 21 is fixed to the top of the support frame 1. The bottom end of the push rod of the upper driving push rod 21 is fixed to the middle lifting seat 5. The push rod of the upper driving push rod 21 is connected to the upper lifting seat 4 for upward and downward sliding. A connecting piece is installed between the upper lifting seat 4 and the lower lifting seat 6. A vertical tension spring 23 is fixed between the upper lifting seat 4 and the middle lifting seat 5. The middle lifting seat 5 has a tendency to approach the upper lifting seat 4 under the elastic tension of the tension spring 23.
[0038] Furthermore, as an implementation scheme of a vertical push-pull mechanism, when the upper driving push rod 21 extends and retracts the push rod, the upper lifting seat 4 and the lower lifting seat 6 can be moved up and down through the connecting piece. During the movement, if there is no obstacle, the middle lifting seat 5 can be driven to move together through the tension spring 23. When the upper driving push rod 21 extends the push rod and the downward movement of the upper lifting seat 4 or the lower lifting seat 6 is blocked, the middle lifting seat 5 can continue to move downward for a distance, which depends on the distance between the upper lifting seat 4 and the lower lifting seat 6.
[0039] The connecting parts include a No. 2 light rod 24, a No. 1 screw rod 25, a No. 2 light tube 26, and a No. 1 screw tube 27. The upper lifting seat 4 is fixed with a vertical No. 2 light rod 24 at the rear of the bottom end, and the front of the bottom end is rotatably connected with a vertical No. 1 screw rod 25. The lower lifting seat 6 is fixed with a vertical No. 2 light tube 26 at the rear of the top, and a vertical No. 1 screw tube 27 is fixed at the front of the top. The No. 2 light rod 24 and the No. 2 light tube 26 are slidably connected up and down, and the No. 1 screw rod 25 is threadedly connected with the No. 1 screw tube 27. A vertical lower driving push rod 28 is fixed to the bottom of the support frame 1, and the top end of the push rod of the lower driving push rod 28 is fixed to the bottom end of the support platform 12. The support platform 12 is slidably connected to the accommodating groove 9 up and down, and the No. 2 light tube 26 and the No. 1 screw tube 27 are slidably connected to the middle lifting seat 5 up and down.
[0040] Furthermore, the distance between the No. 1 screw rod 25 and the No. 1 screw barrel 27 can be adjusted by rotating the No. 1 screw rod 25 forward and backward, thereby adjusting the distance between the upper lifting seat 4 and the lower lifting seat 6, and then the height of the support platform 12 relative to the accommodating groove 9 can be adjusted by the lower driving push rod 28, so that after the bottom end of the lower lifting seat 6 is fitted with the top end of the support platform 12, the top end of the upper lifting seat 4 can be no higher than the bottom end of the sliding seat 2, that is, the height of the non-closed frame 39 after the "U" frame 38 is cold rolled is indirectly adjusted, so as to adapt to different height requirements for the emergency stop frame 41.
[0041] The cross-section of the through hole 13 is a regular hexagon, and a plurality of plug rods 29 are fixed to the bottom end of the accommodating groove 9. Each of the plug rods 29 corresponds to each of the through holes 13 up and down, and each of the plug rods 29 can be inserted into the through holes 13 with a gap. The upper driving push rod 21 and the lower driving push rod 28 are both hydraulic push rods. A hydraulic control system 40 is fixed to the bottom of the support frame 1, and the hydraulic control system 40 is connected to the upper driving push rod 21 and the lower driving push rod 28 for conveying hydraulic oil.
[0042] Furthermore, when assembling the emergency stop frame 41, the driving push rod 28 can be controlled to retract first. At this time, the insertion rod 29 is inserted into the bottom of the through hole 13 of the support platform 12, and then the hexagonal bolt is inserted into the through hole 13 of the support platform 12 with its screw portion facing upward. The circumferential position of the hexagonal bolt can be limited. Then, a hard plate 37 is placed on the support platform 12, and then the non-closed frame 39 is reinstalled into the side groove 10, so that the screw portion of the hexagonal bolt can be inserted into the holes of the hard plate 37 and the non-closed frame 39. Then, the hexagonal nut is installed, and the hard plate 37 and the bottom of the non-closed frame 39 can be conveniently fastened together, thereby improving assembly efficiency.
[0043] The lateral push-pull mechanism includes a main lifting seat 30 and a guide rail 31. The support frame 1 is slidably connected to the main lifting seat 30 up and down. The upper part of the main lifting seat 30 is fixed to the push rod of the upper driving push rod 21. The front and rear parts of the main lifting seat 30 are each limitedly connected with a group of guide rails 31. Two left and right symmetrical guide rails 31 form a group. The two guide rails 31 in each group of guide rails 31 are gathered toward the middle and upper parts. The guide rails 31 of the front and rear parts of the main lifting seat 30 are slidably connected to the front and rear parts of the sliding seat 2. When the upper driving push rod 21 extends the push rod downward, the two sliding seats 2 can slide close to each other through the main lifting seat 30 and the guide rail 31. When the upper driving push rod 21 retracts the push rod upward, the two sliding seats 2 can slide away from each other through the main lifting seat 30 and the guide rail 31.
[0044] The lateral push-pull mechanism includes a main lifting seat 30, a guide rail 31, an upper bidirectional screw rod 32, an upper hinge seat 33, a lower bidirectional screw rod 34, and a lower hinge seat 35. The support frame 1 is slidably connected to the main lifting seat 30 up and down. The upper part of the main lifting seat 30 is fixed to the push rod of the upper driving push rod 21. The front and rear parts of the main lifting seat 30 are each installed with a group of guide rails 31. Two left and right symmetrical guide rails 31 form a group. The two guide rails 31 in each group of guide rails 31 are gathered toward the middle and upper parts. The front upper part and the rear upper part of the main lifting seat 30 are respectively rotatably connected with the upper bidirectional screw rod 32 horizontally along the left and right directions. The left and right parts of the upper bidirectional screw rod 32 have opposite thread rotation directions. The left and right parts of the upper bidirectional screw rod 32 are each threadedly connected with an upper hinge seat 33. Each upper hinge seat 33 is hinged to the upper part of each guide rail 31, and is slidably connected to the main lifting seat 30 left and right. The front lower part and the rear lower part of the main lifting seat 30 are respectively rotatably connected with lower bidirectional screw rods 34 along the left and right horizontal directions. The threads of the left and right parts of the lower bidirectional screw rods 34 are opposite in rotation direction. The left and right parts of the lower bidirectional screw rods 34 are each threadedly connected with a lower hinge seat 35. Each lower hinge seat 35 is respectively plugged with a gap with each guide rail 31, and is slidably connected with the main lifting seat 30 left and right. The guide rail 31 can swing and slide left and right relative to the lower hinge seat 35. The guide rail 31 is plugged with a gap with the front and rear parts of the sliding seat 2. The guide rail 31 can swing and slide left and right relative to the sliding seat 2. When the upper driving push rod 21 extends the push rod downward, the two sliding seats 2 can slide close to each other through the main lifting seat 30 and the guide rail 31. When the upper driving push rod 21 retracts the push rod upward, the two sliding seats 2 can slide away from each other through the main lifting seat 30 and the guide rail 31.
[0045] When the distance between the upper lifting seat 4 and the lower lifting seat 6 is changed by the connecting piece, that is, when the height of the non-closed frame 39 after forming is adjusted, the distance between the two upper hinged seats 33 can be adjusted by rotating the upper bidirectional screw rod 32 forward and backward, and the distance between the two lower hinged seats 35 can be adjusted by rotating the lower bidirectional screw rod 34 forward and backward, so as to adjust the inclination degree and the left and right distance of the guide rail 31, and then adapt to the upper lifting seat 4 and the lower lifting seat 6 after adjusting the upper and lower distances, so as to achieve smooth cold rolling of the "U" frame 38. For example, when the distance between the upper lifting seat 4 and the lower lifting seat 6 increases, the left and right distance between the guide rails 31 increases accordingly, so as to adjust the distance between the two sliding seats 2, which is not only conducive to adapting to longer square tube profiles 36, but also can ensure that when the adjacent ends of the two sliding seats 2 are flush with the side walls of the side groove 10, the top of the upper lifting seat 4 is not higher than the bottom of the sliding seat 2, and the sliding seats 2 can continue to approach each other to achieve cold rolling.
[0046] A method for using an emergency stop rack production device comprises the following steps: Step 1: Control the vertical push-pull mechanism to lift the upper lifting seat 4, the middle lifting seat 5 and the lower lifting seat 6, and then control the horizontal push-pull mechanism to move the two sliding seats 2 away from each other and move to a suitable position, and then stack two rectangular hard plates 37 (such as steel plates) whose front-to-back spacing is consistent with the front-to-back spacing of the support platform 12 and the left-to-right spacing is consistent with the left-to-right spacing of the accommodating groove 9 and place them horizontally on the top of the support platform 12, and then place two square tube profiles 36 (such as aluminum alloy square tubes) that are easy to cold roll in the discharge grooves 3 at the front and rear parts of the two sliding seats 2, so that the left and right parts of the square tube profile 36 match the discharge groove 3, and the length is shorter than the maximum spacing of the discharge groove 3 in which it is located.
[0047] Step 2: Control the vertical push-pull mechanism to move the lower lifting seat 6 downward, so that the lower groove 8 is used to cold-roll the square tube profile 36 so that it gradually becomes a "U" shape, and insert it into the side groove 10 for shaping to form a "U"-shaped frame 38.
[0048] Step 3: After or simultaneously with step 2, the vertical push-pull mechanism is controlled to move downward, and the drilling rig 11 is controlled to rotate at the same time, so that the drill bit of the drilling rig 11 can be used to drill holes in the "U"-shaped frame 38 and the two hard plates 37 through the through hole 13.
[0049] Step 4: After or simultaneously with step 3, the vertical push-pull mechanism is controlled to move so that the upper lifting seat 4 moves downward until the top of the upper lifting seat 4 is not higher than the bottom of the sliding seat 2.
[0050] Step 5: After or at the same time as step 4, control the movement of the lateral push-pull mechanism to make the two sliding seats 2 approach each other. When the adjacent ends of the two sliding seats 2 are flush with the side walls of the side grooves 10, it should be ensured that the top of the upper lifting seat 4 is not higher than the bottom of the sliding seat 2. Then continue to move to bend the upper part of the "U"-shaped frame 38 to the middle, forming a non-closed frame 39 with a gap in the upper part.
[0051] Step 6: Control the lateral push-pull mechanism to move the two sliding seats 2 away from each other to a suitable position, and control the vertical push-pull mechanism to lift the upper lifting seat 4, the middle lifting seat 5 and the lower lifting seat 6 until the non-closed frame 39 is disengaged from the side groove 10, and then the two non-closed frames 39 are disengaged from the upper lifting seat 4, the middle lifting seat 5 and the lower lifting seat 6 from the front and rear directions respectively, and then reinsert into the side groove 10.
[0052] Step 7: Control the vertical push-pull mechanism to move so that the lower lifting seat 6 moves downward until the top of the lower groove 8 contacts the upper part of the non-closed frame 39 .
[0053] Step 8: Control the vertical push-pull mechanism to move so that the middle lifting seat 5 moves downward, and at the same time control the drilling machine 11 to rotate, so that the drill bit of the drilling machine 11 can be used to drill holes in the upper part of the non-closed frame 39 through the through hole 13.
[0054] Step 9: Control the horizontal push-pull mechanism to move the two sliding seats 2 away from each other to a suitable position, control the vertical push-pull mechanism to lift the upper lifting seat 4, the middle lifting seat 5 and the lower lifting seat 6, and then disengage the non-closed frame 39 from the side groove 10, and then pull out the two hard plates 37, and then use bolts and nuts to assemble the non-closed frame 39 and the hard plate 37 to form an emergency stop frame 41.

For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
