Description

Technical Field

[0001] The invention relates to a test bench for testing the packaging action of a horizontal high-line packaging head and a testing method thereof. Background Art

[0002] High-speed wire usually refers to the wire rod rolled by "high-speed twist-free rolling mill", the most common of which are ordinary low-carbon steel twist-free controlled cooling, hot-rolled wire rod (ZBH4403-88) and high-quality carbon steel twist-free controlled cooling, hot-rolled wire rod (ZBH44002-88). The rolling speed of high-speed wire is 80-160 m / s, the weight of each wire (coil weight) is 1.8-2.5 tons, the dimensional tolerance is high (can reach 0.02mm), and the different requirements of the products can be met by adjusting the process parameters (especially on the cooling line) during the rolling process.

[0003] As an important part of the wire production process, the horizontal high-wire baler is responsible for baling the coils and is a key equipment in the finished product finishing area. The quality of the baler is directly related to the appearance and packaging quality of the coils.

[0004] During the baling process of the horizontal high-wire baler, the baling wire on the front wire-taking device is transported to the coil through the wire feeding device, baling head and guide groove system on the horizontal high-wire baler, and then re-enters the baling head for baling. Therefore, the baling head is an important part of the horizontal high-wire baler. The reliability of its clamping, twisting, shearing and other actions on the baling wire directly affects whether the baling can be successful in the later stage. Therefore, the baling head needs to be tested for related actions before the baler leaves the factory.

[0005] At present, the test of the baling head is carried out on the whole baler, that is, the baling function is tested after the baling head is installed on the baler: first, the baling head is installed on the baling head transverse seat, and then the baling head transverse seat is fixed on the pressure plate of the platen car, and then a coil is placed, and the relevant program is started to pack the coil and perform relevant tests: if the relevant actions of packaging are correct, it means that the baling head is qualified, and the baling head is removed, and it is transported to the manufacturer together with the parts of the baler and installed again; if the relevant actions of packaging are incorrect, it means that the baling head is unqualified, and the baling head is removed and repaired. The repaired baling head is reinstalled on the baler to test the relevant actions, and then removed after passing. As can be seen from the above, the existing operation of installing the baling head on the baler for online testing is very inconvenient and greatly delays production. Therefore, there is an urgent need for a test bench for offline testing of the baling function of the baling head. Summary of the invention

[0009] Furthermore, the secondary line guide groove also includes a linear guide groove and four arc guide groove support plates. The linear guide groove is arranged at the outlet end of the packing head line, one end of which is connected to the packing head and the other end is connected to the arc guide groove. A flap is arranged on the linear guide groove; two arc guide groove support plates are respectively arranged on the middle bracket and the right bracket, and the arc guide groove support plates are supported on the arc guide groove.

[0013] Furthermore, step II is specifically as follows: the wire feeding device feeds the baling wire into the wire path of the baling head through the linear guide groove, and the baling wire coming out of the baling head enters the wire path of the baling head again through the linear guide groove, the circular arc guide groove on the right, the oblique guide groove, and the circular arc guide groove on the left.

[0014] Furthermore, step III is specifically as follows: the end of wire feeding refers to the dynamic clamp in the clamping unit of the baling head clamping the wire end of the baling wire after the wire end of the baling wire enters the clamping area of ​​the baling head again; manually opening the baling head cover refers to loosening the press-type elbow clamp to put the cover of the baling head in an open state, preparing for the baling wire to be wound up; when the wire feeding wheel in the wire feeding device reverses to wind up the wire, the baling wire flips up all the wire path flaps on the linear guide groove and the oblique guide groove, and the baling wire is pulled out from the circular arc guide groove, the linear guide groove and the oblique guide groove.

[0015] Furthermore, in step IV: winding is completed when the winding length reaches a certain distance, that is, the winding can be stopped after the baling line leaves the linear guide groove, the arc guide groove, and the oblique guide groove, and the winding is completed at this time; the baling function of the baling head test includes twisting, shearing, and spitting the baling line; first, the twisting unit in the baling head is swung into the twisting position, and the twisting motor starts to twist; after the twisting is completed, the ratchet trigger mechanism in the twisting unit causes the twisting gear to rotate and reset; then the movable shear blade in the shearing unit in the baling head rises to cut the baling line, and then the movable clamp in the clamping unit in the baling head returns to the original position to loosen the wire end of the baling line, and finally the twisting unit of the baling head is swung out to spit out the knot, and the baling function test of the baling head is completed at this time.

[0016] Furthermore, the movement process of the baling wire is as follows: first pull out the baling wire, pull the baling wire toward the wire feeding device, and the length is enough to feed the wire end into the wire feeding wheel; open the clamping roller on the machine side operation cabinet; pull out the locking pin on the entrance guide and open the entrance guide; insert the baling wire end into the gap between the wire feeding wheel and the clamping roller through the entrance guide; close the clamping roller on the machine side operation cabinet, and then press the wire feeding button of the wire feeding wheel to make the baling wire pass through the wire feeding wheel into the linear guide groove, and lock the entrance guide with the locking pin ; Continue to press the wire feeding button of the wire feeding wheel, so that the baling wire end comes out of the baling head, passes through the secondary wire feeding guide groove, and then enters the clamping unit of the baling head again and is clamped by the dynamic clamp in the clamping unit; then press the wire taking-up button to reverse the wire feeding wheel to tighten the baling wire; then press the one-touch operation button to swing the knotting unit into the knotting position to twist the baling wire, the dynamic shear blade of the shearing unit cuts the baling wire, and the knotting unit swings out to spit out the knot; take the cut baling wire segment out of the baling head.

[0017] The advantages of the horizontal high-wire baling head test bench of the present invention are: First, the wire feeding device is used to feed and recycle the baling wire, and the press-type elbow clamp closes and opens the cover plate on the baling head, thereby ensuring the transportation and reversal of the baling wire.

[0024] Among them, the left bracket 3, the middle bracket 4, and the right bracket 5 fixed on the base 1 play the role of supporting the wire feeding device 2, the wire channel system and other components. The function of the wire feeding device 2 is to feed and recycle the baling wire. The function of the press-type elbow clamp 12 is to close and open the cover plate 14 on the baling head 6, so as to ensure the transportation and reversal of the baling wire. The function of the wire channel system is to guide the baling wire and smoothly feed the baling wire into the baling head 6: the function of the baling head 6 is to guide the baling wire and test the baling actions such as clamping, twisting, and shearing; the function of the primary wire guide groove, that is, the linear guide groove 7, is to guide the baling wire coming out of the wire feeding device 2 into the wire channel of the baling head 6, and the function of the secondary wire guide groove is to guide the baling wire coming out of the wire channel of the baling head 6 again into the wire channel of the baling head 6; that is, the baling wire coming out of the wire feeding device 2 enters the wire channel of the baling head 9 through the primary wire guide groove, and the baling wire coming out of the baling head 9 enters the wire channel of the baling head 9 again through the secondary wire guide groove, and reaches the clamping unit of the baling head 9. Therefore, the horizontal high-line strapping head test bench of the present invention can realize the offline test of the strapping function of the assembled new strapping head, which is easy to operate, saves test time, reduces test cost, and greatly improves the efficiency of the production of strapping machines. In addition, when the strapping head needs to be replaced, a qualified strapping head can be directly provided so that it can be installed on the strapping machine to work, instead of installing the replaced strapping head on the strapping machine and then testing to determine whether the strapping head is qualified, which greatly reduces the cost of strapping head spare parts, shortens the maintenance time of the strapping machine, and improves the utilization efficiency of the strapping machine.

[0025] In addition to the mechanical part, the packing head of the present invention also includes a hydraulic control system and an electrical control system.

[0026] Example 2

[0027] In the horizontal high-line baling head test bench: the secondary line inlet guide groove includes two left and right arc guide grooves 8 and an inclined guide groove 9; the two arc guide grooves 8 are respectively arranged on the left and right sides of the baling head 6 line, and their upper ends are connected to the baling head 6, and their lower ends are connected to the inclined guide groove 9; the slot width of the inclined guide groove 9 gradually narrows from the inlet end of the baling line to the outlet end of the baling line, and a flap 16 is arranged on the inclined guide groove 9.

[0028] The baling wire coming out of the wire feeding device 2 enters the wire path of the baling head 6 through the linear guide groove 7. The baling wire coming out of the baling head 6 enters the wire path of the baling head through the arc guide groove 8 connected to the baling head outlet, the oblique guide groove 9, and the arc guide groove 8 connected to the baling head inlet for a second time. When the baling wire reaches the clamping unit, the wire feeding is completed. Here, the left and right arc guide grooves 8, the oblique guide groove 9 and the wire path of the baling head 6 form a complete annular guide groove, so that the baling wire can smoothly enter the baling head for a second time, ensuring that the baling head can test the baling actions such as clamping, twisting, and shearing on the baling wire. Among them, the width of the slot for the baling wire to enter the inclined guide groove 3 is relatively wide, ensuring that the baling wire can smoothly enter the inclined guide groove 3 from the circular arc guide groove 2; the width of the slot for the baling wire to leave the inclined guide groove 3 is relatively narrow, ensuring that the baling wire can smoothly enter the circular arc guide groove 2 from the inclined guide groove 3; a flap 16 is provided on the top of the inclined guide groove 3, and the flap 16 covers the inclined guide groove 3 so that the wire path is closed to ensure that the baling wire is transported in the wire path. At the same time, when the wire is reeled in, the baling wire opens the flap 16 to separate the baling wire from the inclined guide groove 3, which is convenient for the baling head to test the corresponding baling action.

[0029] Example 3

[0030] In the horizontal high-line packaging head test bench: the secondary line guide groove also includes a linear guide groove 10 and four arc guide groove support plates 11. The linear guide groove 10 is arranged at the outlet end of the packaging head 6 line, one end of which is connected to the packaging head 6, and the other end is connected to the arc guide groove 8. A flap 16 is arranged on the linear guide groove 10; two arc guide groove support plates 11 are respectively arranged on the middle bracket 4 and the right bracket 5, and the arc guide groove support plates 11 are supported on the arc guide groove 8.

[0031] Among them, the linear guide groove 10 can better ensure that the baling line in the baling head 6 enters the circular arc guide groove 8 smoothly; a flap 16 is arranged below the linear guide groove 10, and the flap 16 covers the linear guide groove 10 so that the line is closed to ensure that the baling line is transported in the line. At the same time, when the line is reeled in, the baling line opens the flap 16 to separate the baling line from the linear guide groove 10, which is convenient for the baling head to test the corresponding baling action. The circular arc guide groove support plate 11 plays the role of supporting the circular arc guide groove 8, thereby ensuring that the baling line runs smoothly in the guide groove. Among them, the two circular arc guide groove support plates 11 on the same bracket are respectively supported on the front and rear sides of the circular arc guide groove 8. This arrangement can better play a supporting role.

[0032] Example 4

[0033] In the horizontal high-wire packing head test bench: the linear guide groove 7 and the arc guide groove 8 on the left are arranged front and back, and the contact surfaces of the two are on the same plane as the central section surface of the lower wire track of the packing head 6.

[0034] This structure allows the baling wire to smoothly enter the wire path of the baling head 6 once and twice.

[0035] Example 5

[0036] In order to describe and understand the test method, the structure of the wire feeding device 2 and the packing head 6 in the test bench is briefly introduced below: the wire feeding device 2 includes a clamping roller, an entrance guide, a wire feeding wheel, and an exit guide; the packing head 6 includes a clamping unit, a shearing unit, and a twisting unit.

[0037] The testing method of the horizontal high-wire baling head test bench comprises the following steps: Ⅰ, the baling head 6 is installed on the test bench, and the baling head cover 14 is closed; Ⅱ, the wire feeding device 2 sends the baling wire 15 to the wire channel system; Ⅲ, after the wire feeding is completed, the baling head cover 14 is manually opened, and the wire feeding wheel in the wire feeding device 2 is reversed to reel in the wire; Ⅳ, after the wire reeling is completed, the baling head 6 starts to test the baling function; Ⅴ, the baling head 6 is removed from the test bench.

[0038] Step I is specifically as follows: firstly, the baling head 6 to be tested is mounted on the intermediate bracket 5 on the base 1 by means of bolts, and is connected to the oil pipe of the hydraulic system and the cable of the electronic control system; then, the pressing type toggle clamp 12 is pressed to close the cover plate 14 of the baling head 6, so that the wire path on the baling head 6 is closed, and preparation is made for the baling wire 16 to enter the wire path of the baling head.

[0039] Step II is specifically as follows: the wire feeding device 2 feeds the baling wire into the wire path of the baling head 6 via the linear guide groove 7; the baling wire coming out of the baling head 6 enters the wire path of the baling head 6 again via the linear guide groove 10, the circular arc guide groove 8 on the right, the oblique guide groove 9, and the circular arc guide groove 8 on the left.

[0040] Step III is specifically as follows: the end of wire feeding means that after the end of the baling wire enters the clamping area in the baling head 6 again, the dynamic clamp in the clamping unit in the baling head 6 clamps the end of the baling wire; manually opening the baling head cover means loosening the press-type elbow clamp 12 to make the cover 14 of the baling head 6 in an open state, preparing for the baling wire to be wound up; when the wire feeding wheel in the wire feeding device 2 reverses to wind up the wire, the baling wire 15 turns over all the wire path flaps 16 on the linear guide groove 10 and the oblique guide groove 9, and the baling wire is pulled out from the circular arc guide groove 8, the linear guide groove 10, and the oblique guide groove 9.

[0041] In step IV: the completion of the winding means that the winding length reaches a certain distance, that is, the winding can be stopped after the baling wire leaves the linear guide groove, the arc guide groove, and the inclined guide groove. Figure 2 As shown in , the line is collected at this time.

[0042] In step IV: the packing function of the packing head 6 test includes twisting, shearing and spitting out the packing line; first, the twisting unit in the packing head is swung into the twisting position, and the twisting motor starts to twist; after the twisting is completed, the ratchet trigger mechanism in the twisting unit causes the twisting gear to rotate and reset; then the movable shear blade in the shearing unit in the packing head rises to cut the packing line, and then the movable clamp in the clamping unit in the packing head returns to the original position to loosen the thread end of the packing line, and finally the twisting unit of the packing head is swung out to spit out the knot, and the packing function test of the packing head is completed at this time.

[0043] In step V: Before removing the baling head, the main pump of the hydraulic system needs to be turned off.

[0044] The baling head test bench of the present invention is connected to the main PLC system in an electronically controlled manner, so that it can operate as an independent device in the factory. The baling head test bench of the present invention is manually operated beside the machine, without remote control and interlocking. The baling head test bench of the present invention is used to individually test whether the functions of each part of the baler are normal, so only a single baling head is manually tested individually. The baling head 6 in the present invention is equipped with complete and independent hydraulic and electrical equipment, and the configuration of its piping and control valve block allows the baling head to be easily installed on the baling machine host, and all cables and hydraulic hoses are equipped with quick connectors.

[0045] The movement process of the baling wire 15 is as follows: first pull out the baling wire, pull the baling wire toward the wire feeding device 2, and the length is enough to feed the wire end into the wire feeding wheel; open the clamping roller on the machine side operation cabinet; pull out the locking pin on the entrance guide and open the entrance guide; insert the baling wire end into the gap between the wire feeding wheel and the clamping roller through the entrance guide; close the clamping roller on the machine side operation cabinet, and then press the wire feeding button of the wire feeding wheel to make the baling wire pass through the wire feeding wheel and enter the linear guide groove 7, and lock the entrance guide with the locking pin dead; continue to press the wire feeding button of the wire feeding wheel, so that the baling wire end comes out of the baling head 6 and passes through the secondary wire feeding guide groove and then enters the clamping unit of the baling head again and is clamped by the dynamic clamp in the clamping unit; then press the wire taking-up button to reverse the wire feeding wheel to tighten the baling wire; then press the one-touch operation button to swing the knotting unit into the knotting position to twist the baling wire, the dynamic shear blade of the shearing unit cuts the baling wire, and the knotting unit swings out to spit out the knot; take the cut baling wire segment out of the baling head.

[0046] During the test, the strapping head performs corresponding tests on the following functions: 1. Swinging in and out of the twisting unit; twisting and resetting the twisting unit; 2. The moving clamp in the clamping unit clamps and resets from the initial original position to the wire feeding position to the clamping position; 3. The moving shear blade in the shearing unit shears and resets from the initial original position to the shearing position. If the action test is correct, it means that the strapping head 6 is qualified; if the action test is wrong, it means that the strapping head 6 is unqualified and the strapping head needs to be repaired. The repaired strapping head is reinstalled on the strapping head test bench and the relevant actions are tested until it is qualified.

The test method according to claim 4 is characterized in that: in step IV: the completion of winding means that after the winding length reaches a certain distance, that is, the winding can be stopped after the baling line leaves the linear guide groove (10), the arc guide groove (8), and the inclined guide groove (9), and the winding is completed at this time; the baling function tested by the baling head (6) includes twisting, shearing, and spitting the baling line; first, the twisting unit in the baling head is swung into the twisting position, and the twisting motor starts to twist; after the twisting is completed, the ratchet trigger mechanism in the twisting unit causes the twisting gear to rotate and reset; then the movable shear blade in the shearing unit in the baling head rises to cut the baling line, and then the movable clamp in the clamping unit in the baling head returns to the original position to loosen the wire end of the baling line, and finally the twisting unit of the baling head is swung out to spit out the knot, and at this time the baling function test of the baling head is completed.

9. The testing method according to claim 4, characterized in that: The movement process of the baling wire (15) is as follows: first pull out the baling wire, pull the baling wire toward the wire feeding device (2), and the length is enough to feed the wire end into the wire feeding wheel; open the clamping roller on the machine side operation cabinet; pull out the locking pin on the entrance guide and open the entrance guide; insert the baling wire end into the gap between the wire feeding wheel and the clamping roller through the entrance guide; close the clamping roller on the machine side operation cabinet, and then press the wire feeding button of the wire feeding wheel to make the baling wire pass through the wire feeding wheel and enter the linear guide groove (7), and lock the entrance guide with the locking pin. The baling wire is then locked; the wire feeding button of the wire feeding wheel is continuously pressed, so that the baling wire end comes out of the baling head (6), passes through the secondary wire feeding guide groove, and then enters the clamping unit of the baling head again and is clamped by the dynamic clamp in the clamping unit; the wire rewinding button is then pressed to reverse the wire feeding wheel and tighten the baling wire; the one-touch operation button is then pressed to swing the knotting unit into the knotting position to twist the baling wire, the dynamic shear blade of the shearing unit cuts the baling wire, and the knotting unit swings out to spit out the knot; the cut baling wire segment is taken out from the baling head.
