Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing and prefabricated part production, and in particular to stirrup processing equipment, a stirrup processing system and a sleeper production line. Background Art

[0002] Stirrups are widely used in the production process of prefabricated parts. For example, stirrups are an important part of the metal skeleton of sleepers. In the mass production of sleepers, stirrups are used in large quantities. How to quickly, efficiently and with high quality realize the processing and production of stirrups is of great significance to the production of prefabricated parts using them.

[0003] In the production process of some stirrups, it is necessary to weld the stirrups to improve the mechanical properties of the prefabricated parts using the stirrups. In the actual production process, the steel bars must first be bent into stirrups, and then the stirrups must be welded. In the automated production of stirrups, after the stirrups are welded, they must also be inspected and / or transported. How to make stirrup processing equipment have automated welding, inspection and transport functions to achieve efficient and high-quality processing of stirrups is an urgent problem to be solved by those skilled in the art.

[0004] In addition, during the bending process of the steel bars, the bending sections of the stirrups may be twisted and deformed, resulting in the bending sections of the stirrups not being on the same plane, making it difficult to meet the welding conditions. Therefore, the stirrups formed by the bending need to be placed on the welding workbench and reasonably constrained to achieve a state that can be welded. How to constrain the stirrups to the set welding position without human assistance is the key to ensuring the welding quality of the stirrups, and it is also a technical problem that is difficult for technicians in this field to overcome.

The control unit further controls the control valve, and can selectively switch the control valve to a position where the telescopic rod of the pneumatic telescopic cylinder can be extended, or switch the control valve to a position where the telescopic rod of the pneumatic telescopic cylinder can be retracted. In a specific implementation, the control valve is preferably set to a two-position five-way electromagnetic reversing valve, etc.

[0141] As some convertible implementations of the present application, the third push-pull assembly 15 is a hydraulic telescopic cylinder, and the hydraulic telescopic cylinder is connected through a control valve, a hydraulic pump and a hydraulic source fluid circuit. In specific implementation, the control unit controls the control valve, and can selectively switch the control valve to a position where the telescopic rod of the hydraulic telescopic cylinder can be extended, or switch the control valve to a position where the telescopic rod of the hydraulic telescopic cylinder can be retracted. In specific implementation, the control valve is preferably set to a two-position five-way electromagnetic reversing valve or a three-position five-way electromagnetic reversing valve.

[0142] Specific as Figures 6 to 8 As shown, the cylinder body of the third push-pull assembly 15 is fixed on the upper surface of the supporting platform 11, and the telescopic direction of the telescopic rod of the third push-pull assembly 15 is perpendicular or substantially perpendicular to the push-pull direction of the first push-pull assembly 13. Under the action of the third push-pull assembly 15, the first straight section 63 of the stirrup 6 can be pushed toward the inner side of the main body of the stirrup to a set position.

[0143] Similarly, the fourth push-pull assembly 16 in the present application is not specifically limited, and it can be any push-pull assembly that can move the first straight section 63 of the stirrup toward the outside of the main body of the stirrup to a set position. In a specific implementation, the fourth push-pull assembly 16 can be selectively set to a push-pull assembly including a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, a screw slider module, a gear rack module, a linear motor, etc. In a specific implementation, it is preferred that the fourth push-pull assembly 16 is a pneumatic telescopic cylinder, and the pneumatic telescopic cylinder is connected to the pressure gas source (gas pressure tank, gas pump, etc.) through a control valve.

In specific operation, the control unit controls the control valve, and can selectively switch the control valve to a position where the telescopic rod of the hydraulic telescopic cylinder can be extended, or switch the control valve to a position where the telescopic rod of the hydraulic telescopic cylinder can be retracted. In specific implementation, it is preferred that the control valve is set to a two-position five-way electromagnetic reversing valve or a three-position five-way electromagnetic reversing valve. Specifically, Figures 6 to 8 As shown, the cylinder body of the fourth push-pull assembly 16 is fixed on the upper surface of the supporting platform 11, and the pushing direction of the telescopic rod of the fourth push-pull assembly 16 is opposite to the pushing direction of the third push-pull assembly 15. Under the action of the fourth push-pull assembly 16, the first straight section 63 of the stirrup can be pushed toward the outside of the main body of the stirrup to a set position.

[0145] It should also be noted that the "first straight section" in the present application is a component of the stirrup, specifically a straight section adjacent to the second welding section 62 of the stirrup 6 (specifically, Fig.16 and Fig.17 shown).

[0146] The present application enables the third push-pull assembly 15 included in the welding workbench 1 to push the first straight section 63 adjacent to the second welding section 62 to move to the set position toward the inside of the stirrup body, thereby driving the second welding section 62 to quickly move toward the set welding position, and further through the fourth push-pull assembly 16, the position of the first straight section 63 can be corrected, thereby enabling the second welding section 62 to be accurately positioned. Under the joint action of the first push-pull assembly 13 and the second push-pull assembly 14, the stirrup 6 formed by bending can better meet the welding conditions; further improving the finished product qualification rate of the stirrup 6 and the efficiency of the stirrup 6 welding.

[0147] As some preferred embodiments of the present application, at least one of the first push-pull assembly 13, the second push-pull assembly 14, the third push-pull assembly 15 and the fourth push-pull assembly 16 is further selectively set as a pneumatic telescopic cylinder or a hydraulic telescopic cylinder.

Furthermore, a stop surface 171 of the positioning stopper 17 is directly opposite to the push-pull end of the fourth push-pull assembly 16 .

[0149] It should also be pointed out that the position of the stop surface 171 of the positioning stop 17 is determined according to whether the stirrup 6 meets the welding conditions. In the present application, the welding workbench 1 includes the positioning stop 17, and under the action of the positioning stop 17, the fourth push-pull assembly 16 can correct the position of the first straight section 63 of the stirrup 6, so that the stirrup 6 better meets the welding conditions, thereby improving the qualified rate of the finished product of the welded stirrup 6.

[0150] As some preferred embodiments of the present application, the pressing unit 12 further selectively includes a telescopic assembly 121, a pressing member 122, a hinged support 123 and a connecting arm 124. Figures 6 to 10 As shown, the telescopic assembly 121 is fixed on the bearing platform 11, and the telescopic end 1211 of the telescopic assembly can extend upward to a first position and retract downward to a second position. In the specific working process, when the telescopic end extends to the first position, the pressing member 122 is in a position capable of pressing the stirrup 6 to the bearing platform 11; when the telescopic end retracts to the second position, the pressing member 122 is in a position away from the stirrup 6.

[0151] In specific implementation, Figure 7.1 , Fig. 9 and Fig.10 As shown, the clamping member 122 can be further selectively made into a strip structure including a connecting end 1221 and a clamping end 1222, the clamping portion is located at the clamping end 1222, the connecting end 1221 of the clamping member 122 is hinged to the telescopic end 1211 of the telescopic assembly; the hinged support 123 is fixed on the bearing platform 11, and the hinged support 123 is located between the telescopic end and the contour of the stirrup 6 during welding; one end of the connecting arm 124 is hinged to the hinged support 123, and the other end of the connecting arm 124 is hinged to the clamping member 122, and the hinged position of the connecting arm 124 and the clamping member 122 is located between the connecting end 1221 and the clamping end 1222. Figure 6 As shown, the pressing unit 12 includes two connecting arms 124, and the pressing member 122 is connected to the hinge support 123 through the two connecting arms 124. As a convertible embodiment, the pressing unit 12 includes one connecting arm 124, and the pressing member 122 is connected to the hinge support 123 through one connecting arm 124.

[0152] The present application enables the pressing unit 12 to include a telescopic assembly 121, a pressing member 122, a hinged support 123 and a connecting arm 124, so that the pressing unit 12 can press and release the stirrup 6 during the telescopic process of the telescopic assembly 121, thereby quickly positioning the bent stirrup 6 in the vertical direction. When the telescopic assembly 121 is a pneumatic telescopic cylinder or a hydraulic telescopic cylinder, the pressing unit 12 can press the stirrup 6 through the control unit, thereby providing technical support for the automated processing of the stirrup 6. In addition, the present application hinges the clamping member 122 with one end of the connecting arm 124, and hinges the other end of the connecting arm 124 with the hinged support 123. When the clamping unit 12 is working, under the action of the connecting arm 124, the clamping member 122 can swing during the rotation process, so that the clamping end 1222 of the clamping member 122 can be clamped or moved away from the stirrup 6 more quickly; not only that, in the process of releasing the stirrup 6, the clamping end 1222 of the clamping member 122 can be moved out of the position directly above the stirrup 6, which is convenient for obtaining the stirrup 6 during transportation, especially for realizing the automated acquisition of the stirrup.

[0153] As some preferred embodiments of the present application, the welding workbench 1 further selectively includes a first supporting member 181, and the first supporting member 181 has a first bearing surface 1811. Figure 6 and Figure 7 As shown, a plurality of first support members 181 are fixed on the bearing platform 11 at intervals along the extension direction of the supported stirrup 6, and the first bearing surfaces 1811 of the plurality of first support members 181 are in the same plane. In specific operation, when the pressing member 122 is in the position of pressing the stirrup 6 to the bearing platform 11, the pressing member 122 can press the stirrup 6 to the first bearing surface 1811. It should be pointed out that the number of the first support members 181 is not specifically limited, and it can be selectively set according to actual needs. In specific implementation, the number of the first support members 181 can be two, three, four, five, six, seven or more than eight. In specific implementation, it is preferred to set the first support member 181 at least at the position of the bearing platform 11 corresponding to the pressing member 122 included in the pressing unit 12. The first support member 181 that can support the stirrup 6 can also be selectively set at other positions of the bearing platform 11. In addition, there is no specific limitation on the structure of the first supporting member 181, which can be any structural form that supports the stirrups 6. In a specific implementation, the first supporting member 181 can selectively be a block structure, a strip structure, or a plate structure.

[0154] It should be noted that the first bearing surfaces 1811 of the multiple first supporting members 181 in the present application are in the same plane, which includes the situation where the first bearing surfaces 1811 of the multiple supporting members are substantially in the same plane due to factors such as processing and installation errors.

[0155] The present application enables the welding workbench 1 to include a plurality of first support members 181, which can provide vertical position-limiting support for the stirrup 6. When the stirrup 6 completes the welding process, it is convenient to take and place the stirrup 6, especially convenient to transport the stirrup 6 in the automated and intelligent processing process of the stirrup 6. For example, when the unit that obtains the stirrup 6 grabs the stirrup 6 with the clamp, the stirrup 6 is in a suspended state under the action of the first support member 181, which is convenient for the clamp to grab the stirrup 6. In addition, by making the first bearing surface 1811 of the first support member 181 on the same plane, the stirrup can be better positioned so that the stirrup can better meet the welding conditions.

[0156] As some preferred embodiments of the present application, Figure 7.2 As shown, the welding workbench 1 further selectively includes a stirrup limiting unit 19, and the stirrup limiting unit 19 has a stirrup limiting groove 191. A plurality of stirrup limiting units 19 are fixed at intervals on the upper surface of the support platform 11, and each stirrup limiting groove 191 extends along the extension direction of the stirrup 6 during welding. It should be noted that the structural form of the stirrup limiting unit 19 is not specifically limited, and it can be any structure, unit or device that includes a stirrup limiting groove 191 and can constrain the stirrup 6. It should also be noted that there is no specific restriction on the number of stirrup limiting units 19 in the present application.

In the present application, the stirrup limiting unit 19 includes a first limiting block 192 and a second limiting block 193, so that the first limiting block 192 and the second limiting block 193 relative to each other form a stirrup limiting groove 191, and this arrangement is not only simple in structure, but also easy to install.

Therefore, when the stirrup 6 is placed on the welding workbench 1, the stirrup 6 can be more easily constrained in the stirrup limiting groove 191 under the action of the clearance gap 194, the first guiding bevel 1921 and the second guiding bevel 1931.

Fig.12As shown, the second positioning member 141 is a plate-shaped structure as a whole, and the second positioning member 141 is fixedly connected to the push-pull end of the second push-pull assembly 14. The second positioning member 141 is provided with two second positioning ribs 1411 protruding toward the second welding section 62, and each second positioning rib 1411 is provided with a second positioning groove 1412 extending along the specified extension direction of the second welding section 62 of the stirrup 6.
