Description

Technical Field

[0001] The present invention relates to the field of vehicle manufacturing, and particularly to a pick-up truck longitudinal beam side straightening die that can independently straighten different points. Background Art

[0002] Pick-up truck longitudinal beams are generally S-shaped U-shaped parts, and the longitudinal beam assemblies are all welded by robots. To ensure the welding strength, full welding is basically required. Therefore, the fitting clearances between the inner and outer plates of the longitudinal beams must be strictly controlled to ensure that the weld clearances meet the welding requirements.

[0003] The fitting clearances between the inner and outer plates of the longitudinal beams need to be controlled within 1.2 mm. Too large a clearance will affect the welding quality level of the longitudinal beam assembly and even the welding strength of the longitudinal beam assembly. In the process of pick-up truck longitudinal beams, a side straightening process needs to be added to control the surface clearance of the longitudinal beam wing surface. Therefore, the design of the side straightening die is particularly crucial.

[0004] The existing pick-up truck longitudinal beam side straightening process straightens the two side wing surfaces of the longitudinal beam as a whole. The main defect of this side straightening technology is that it is difficult to debug. If the surface clearance at one point of the longitudinal beam wing surface exceeds the tolerance, the entire side straightening surface of the longitudinal beam needs to be lapped. Moreover, it often causes the surface clearance at another point of the longitudinal beam to exceed the tolerance after the surface clearance at one point of the longitudinal beam is rectified. Therefore, the rectification process often repeats, which not only affects the product quality but also the production efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a pick-up truck longitudinal beam side straightening die that can independently straighten different points, aiming to solve the technical problem that in the prior art, when the two side wing surfaces of the pick-up truck longitudinal beam are straightened as a whole, after the surface clearance at one point is rectified, due to the influence of the overall straightening, the surface clearance at another point may exceed the tolerance, and thus repeated straightening is required, affecting the product quality and production efficiency.

[0006] To achieve the above object, an embodiment of the present invention provides a pick-up truck longitudinal beam side straightening die capable of independently side straightening different positions, including a corresponding upper die and a lower die. A carrier and a plurality of limit members are arranged on the lower die. The carrier is used to carry the longitudinal beam. The plurality of limit members are evenly distributed at intervals along the length direction of the carrier. The limit member includes two lower die side straightening guide plates located on opposite sides of the carrier. A lower die side straightening guide plate mounting block is arranged on the lower die. The lower die side straightening guide plate is arranged on the surface of the lower die side straightening guide plate mounting block facing the carrier. A blank holding member and a plurality of side straightening members are arranged on the upper die. The position of the blank holding member corresponds to that of the carrier. The number of the side straightening members corresponds to that of the limit members. The side straightening member includes two side straightening concave die inserts located on opposite sides of the blank holding member. An upper die side straightening guide and sliding mounting movable block is movably connected to the upper die. The side straightening concave die insert is arranged on the surface of the upper die side straightening guide and sliding mounting movable block facing the blank holding member. A guide and sliding surface is formed on the upper die side straightening guide and sliding mounting movable block opposite to the side straightening concave die insert. An obtuse angle is formed between the guide and sliding surface and the surface of the upper die side straightening guide and sliding mounting movable block opposite to the upper die. The guide and sliding surface is used to abut against the lower die side straightening guide plate. A gasket is arranged between the side straightening concave die insert and the upper die side straightening guide and sliding mounting movable block.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: When side straightening the longitudinal beam is required, the longitudinal beam is placed on the carrier, and the blank holding member abuts against and fixes the longitudinal beam. At this time, the guide and sliding surface of the side straightening concave die insert abuts against the lower die side straightening guide plate. Due to the angle design of the guide and sliding surface, the lower die side straightening guide plate squeezes the guide and sliding surface, so that the gasket on the side straightening concave die insert abuts against the side wall of the longitudinal beam to complete side straightening. In this application, by splitting out a plurality of the limit members and a plurality of the side straightening members, the longitudinal beam is subjected to segmented side straightening. The side straightening amount can be realized by increasing or decreasing the gasket between the side straightening concave die insert and the upper die side straightening guide and sliding mounting movable block. That is, through segmented side straightening, independent side straightening of different positions of the longitudinal beam can be realized, and the entire flank of the longitudinal beam will not be affected by a single side straightening, effectively improving the product quality and production efficiency.

[0008] Further, 6 of the limit members are arranged on the lower die, 6 of the side straightening members are arranged on the upper die, and the length of the side straightening concave die insert is 300 mm to 350 mm.

[0009] Further, the roughness of the guide and sliding surface is less than 0.8 μm, and the R corner radius of the guide and sliding surface is R20.

[0010] Further, a plurality of bottom rotating bases are arranged on the upper die. The bottom rotating bases correspond to the positions of the upper die side integral guiding and sliding mounting movable blocks. A plurality of screws are rotatably connected to the upper die. A first waist-shaped hole is formed in the bottom rotating base. One end of the screw facing away from the upper die passes through the first waist-shaped hole and is connected to the upper die side integral guiding and sliding mounting movable block. A guiding screw guide sleeve is sleeved outside the screw, and a gap is formed between the guiding screw guide sleeve and the inside of the first waist-shaped hole.

[0011] Further, the blank holder includes a blank holder core. The blank holder core is movably connected to the upper die through working nails. A plurality of abutting blocks are arranged on one side of the blank holder core facing the upper die. A plurality of nitrogen springs corresponding to the positions of the abutting blocks are arranged on one side of the upper die facing the blank holder core. One side of the nitrogen spring facing away from the upper die abuts against the abutting block.

[0012] Further, guide plates slidably connected to the upper die are arranged on two opposite sides of the blank holder core, and a guide sleeve is arranged at the bottom of the blank holder core.

[0013] Further, a butt block is arranged at the bottom of the blank holder core, and a butt fitting plate corresponding to the position of the butt block is arranged on one side of the upper die facing the blank holder core.

[0027] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. Specific embodiments

[0028] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as "fixedly provided on" another element, it can be directly on the other element or there may be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are only for the purpose of illustration.

[0030] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as commonly understood by those skilled in the technical field to which this invention belongs. The terms used in the description of the present invention in this article are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0031] Please refer to Figures 1 to 8 , an embodiment of the present invention provides a pick-up truck longitudinal beam side straightening die that can independently adjust different points. It includes a corresponding upper die 11 and a lower die 01. It can be understood that the upper die 11 and the lower die 01 are vertically corresponding. A carrier and a number of limiters are provided on the lower die 01. The carrier is used to carry the longitudinal beam. Specifically, the carrier includes a number of punch inserts 03. A number of backs that match the punch inserts 03 are provided on the lower die 01. One side wall of the punch insert 03 abuts against the back. The side of the punch insert 03 facing away from the back is detachably connected to the lower die 01 through a key for inserts. By this detachable connection method, it is convenient to replace damaged parts separately. A hidden key for inserts is provided at the bottom of the punch insert 03. A limit hole that matches the hidden key for inserts is provided on the lower die 01. By inserting the hidden key into the limit hole, the movement of the punch insert 03 is restricted to prevent the punch insert 03 from shifting during the side straightening of the pick-up truck longitudinal beam side straightening die, resulting in errors in side straightening.

[0032] One side of the punch insert 03 facing away from the lower die 01 is vertically movably connected to the lifting movable block 04. In this embodiment, a lifting spring is arranged inside the punch insert 03, and the lifting spring is connected to the lifting movable block 04 to realize the vertical movement of the lifting movable block 04. A positioning pin 05 adapted to the longitudinal beam is arranged on the lifting movable block 04. Understandably, a positioning hole adapted to the positioning pin 05 is opened on the longitudinal beam. By inserting the positioning pin 05 into the positioning hole, the fixing work of the longitudinal beam is completed. By arranging the lifting movable block 04, when the side trimming is completed, the longitudinal beam can be separated from the punch insert 03 to complete the blanking work. And by arranging the positioning pin 05 on the lifting movable block 04, it can be ensured that after the longitudinal beam is separated from the punch insert 03, the longitudinal beam can still be fixed. Further, an automatic induction detector 08 is arranged on the lifting movable block 04, and the automatic induction detector 08 is used to detect the position information of the lifting movable block 04, and then judge whether the blanking work is completed through the position information. It should be noted that to ensure that the vertical movement of the lifting movable block 04 will not be stuck, the surface roughness of the side surface of the lifting movable block 04 is less than 0.8 μm, and the lifting movable block 04 needs to be subjected to PVD treatment to improve the surface hardness of the lifting movable block 04.

[0033] A plurality of the limiting members are evenly distributed at intervals along the length direction of the bearing member. The limiting members include two lower die side trimming guide plates 02 located on opposite sides of the bearing member. A lower die side trimming guide plate mounting block 09 is arranged on the lower die 01. The lower die side trimming guide plate 02 is arranged on one side of the lower die side trimming guide plate mounting block 09 facing the bearing member. It should be noted that to prevent the lower die side trimming guide plate mounting block 09 from shifting during the working process, the bottom of the lower die side trimming guide plate mounting block 09 is inserted into the lower die 01 through a mounting key. In this embodiment, the pickup truck longitudinal beam side trimming die includes 6 of the limiting members, that is, 12 of the lower die side trimming guide plates 02.

[0034] A pressure member and a plurality of side trimming members are arranged on the upper die 11. The position of the pressure member corresponds to that of the bearing member. The number of the side trimming members corresponds to that of the limiting members. The side trimming members include two side trimming concave die inserts 17 located on opposite sides of the pressure member. In this embodiment, 6 of the side trimming members are arranged on the upper die 11, that is, 12 of the side trimming concave die inserts 17 are arranged. Preferably, the length of the side trimming concave die insert 17 is 300 mm to 350 mm.

[0035] The blank holder includes a blank holding core 13, and the blank holding core 13 is movably connected to the upper die 11 through working pins 21. In this embodiment, the working pins 21 are M20. To ensure safety in use, safety hanging plates are provided on two opposite sides of the blank holding core 13. On one side of the blank holding core 13 facing the upper die 11, a number of abutting blocks 19 are provided. On one side of the upper die 11 facing the blank holding core 13, a number of nitrogen springs 26 corresponding to the positions of the abutting blocks 19 are provided. The side of the nitrogen spring 26 facing away from the upper die 11 abuts against the abutting block 19, and the blank holding core 13 is driven to move vertically by the nitrogen spring 26, so as to approach or move away from the longitudinal beam. In this embodiment, a spring fixing plate 35 is provided on the upper die 11, and one end of the nitrogen spring 26 facing the upper die 11 is connected to the spring fixing plate 35. Guide plates 18 slidably connected to the upper die 11 are provided on two opposite sides of the blank holding core 13, and a guide sleeve 22 is provided at the bottom of the blank holding core 13. By providing the guide plates 18 and the guide sleeve 22, it can be ensured that the blank holding core 13 moves vertically more smoothly. A butting block 23 is provided at the bottom of the blank holding core 13, and a butting fitting plate 27 corresponding to the position of the butting block 23 is provided on one side of the upper die 11 facing the blank holding core 13. When the upper die 11 reaches the bottom dead center, the butting block 23 abuts against the butting fitting plate 27.

[0036] An upper die side integral guiding and sliding installation movable block 16 is movably connected to the upper die 11. On one side of the upper die side integral guiding and sliding installation movable block 16 facing the blank holder, a side integral concave die insert 17 is provided. The side integral concave die insert 17 is connected to the upper die side integral guiding and sliding installation movable block 16 through a vertical key 15. By providing the vertical key 15, while ensuring work safety, the side integral concave die insert 17 can be prevented from moving longitudinally. To further improve stability, a side integral safety hanging plate is provided on the upper die seat, and the side integral safety hanging plate is inserted into the upper die side integral guiding and sliding installation movable block 16.

[0037] A guiding and sliding surface 20 is formed on the side of the upper die side integral guiding and sliding installation movable block 16 facing away from the side integral concave die insert 17. An obtuse angle is formed between the guiding and sliding surface 20 and the side of the upper die side integral guiding and sliding installation movable block 16 facing away from the upper die 11. The guiding and sliding surface 20 is used to abut against the lower die side integral guiding plate 02. In this embodiment, the angle of the obtuse angle is 135°. Preferably, the roughness of the guiding and sliding surface 20 is less than 0.8 μm, and the R corner radius of the guiding and sliding surface 20 is R20 to ensure smooth contact between the guiding and sliding surface 20 and the lower die side integral guiding plate 02, and thus ensure stable subsequent side integral. A gasket is provided between the side integral concave die insert 17 and the upper die side integral guiding and sliding installation movable block 16.

[0038] When the longitudinal beam needs to be side-adjusted, place the longitudinal beam on the bearing member, and make the blank holder abut and fix the longitudinal beam. At this time, the guiding surface 20 of the side-adjusting concave die insert 17 abuts the lower die side-adjusting guide plate 02. Due to the angle design of the guiding surface 20, the lower die side-adjusting guide plate 02 presses the guiding surface 20, so that the gasket on the side-adjusting concave die insert 17 abuts the side wall of the longitudinal beam to complete the side adjustment. In this application, by splitting out several of the limiting members and several of the side-adjusting members, the longitudinal beam is side-adjusted in a segmented manner. The side-adjustment amount can be achieved by increasing or decreasing the gasket between the side-adjusting concave die insert 17 and the upper die side-adjusting guiding and installing movable block 16. That is, through segmented side-adjustment, independent side-adjustment of different points on the longitudinal beam can be realized, and the entire flank of the longitudinal beam will not be affected by a single side-adjustment, effectively improving the product quality and production efficiency.

[0039] To realize the movement of the side-adjusting concave die insert 17 and thus complete the side adjustment, several bottom rotating bases 29 are arranged on the upper die 11. The bottom rotating bases 29 are fixedly connected to the upper die 11 through pins. The bottom rotating bases 29 correspond to the positions of the upper die side-adjusting guiding and installing movable blocks 16. Several screws 31 are rotatably connected to the upper die 11. Specifically, screw sleeve through holes 24 are arranged on the upper die 11, and the screws 31 are rotatably connected in the screw sleeve through holes 24. In this embodiment, the number of the screws 31 is twice the number of the upper die side-adjusting guiding and installing movable blocks 16, that is, one bottom rotating base 29 corresponds to two screws 31. First waist-shaped holes are formed in the bottom rotating bases 29. The ends of the screws 31 facing away from the upper die 11 pass through the first waist-shaped holes and are connected to the upper die side-adjusting guiding and installing movable blocks 16. Guide screw sleeves 32 are sleeved outside the screws 31, and a gap is formed between the guide screw sleeves 31 and the interiors of the first waist-shaped holes. It can be understood that the guide screw sleeves 32 and the screws 31 can swing within the range of the first waist-shaped holes, thereby realizing the swinging of the side-adjusting concave die insert 17 and the upper die side-adjusting guiding and installing movable blocks 16. It can be understood that in the overall free state, the centers of gravity of the side-adjusting concave die insert 17 and the upper die side-adjusting guiding and installing movable blocks 16 are in an open state, that is, the screws 31 are not in a vertical state.

[0040] Preferably, a plurality of kidney-shaped guide sleeves 33 are provided on the upper die 11. The kidney-shaped guide sleeves 33 are located between the upper die 11 and the bottom rotating base 29. The number of the kidney-shaped guide sleeves 33 corresponds to that of the screws 31. Understandably, kidney-shaped holes are also formed in the kidney-shaped guide sleeves 33, and the screws 31 and the guide screw guide sleeves 32 both pass through the kidney-shaped holes of the kidney-shaped guide sleeves 33. A backing plate 34 is sleeved outside the guide screw guide sleeve 32. The backing plate 34 is located between the upper die 11 and the kidney-shaped guide sleeve 33, and a gap is formed between the backing plate 34 and the kidney-shaped guide sleeve 33. By providing the kidney-shaped guide sleeve 33, the swing of the screw 31 can be limited together with the bottom rotating base 29, and the stability of the overall structure can be improved. By providing the backing plate 34, unnecessary rigid contact can be avoided, and the stability of the overall structure can be improved. In this embodiment, one side of the kidney-shaped guide sleeve 33 facing the upper die 11 has a certain slope to avoid interference between the backing plate 34 and the kidney-shaped guide sleeve 33 during swinging.
