Description

Technical Field

[0001] The invention relates to the technical field of metal parts processing equipment, and in particular to a shearing device used for processing metal mechanical parts. Background Art

[0002] Metal parts shearing device is a device used to shear metal materials into specific sizes and shapes. It is used to shear various metal plates, steel sections, such as steel plates, aluminum plates, copper plates, etc. In industries such as steel rolling, automobiles, ships, and machinery manufacturing, shearing devices are used to shear raw materials to meet production needs.

[0003] In the prior art, in order to meet the requirements of multilateral shearing of metal plates, it is usually necessary to expose the outer edges of the metal plates on the outer side of the support platform. This results in the inability of the existing clamping mechanism to clamp the edges of the metal plates, and it can only clamp the upper and lower end surfaces of the metal plates. In order to avoid obstruction of the clamping mechanism when shearing the metal plates, the clamping mechanism cannot maintain the clamping state of the metal plates during the rotation of the metal plates. In the process of changing sides, it is necessary to first release the clamping state of the metal plates by the clamping mechanism, and then drive the metal plates to rotate along the support plate through the turntable (since the support plate is responsible for supporting the metal plates, its size is usually large, and in order to facilitate the shearing of the metal plates by the shearing mechanism, the support plate and the support platform of the shearing mechanism are usually distributed at the same level. If the support plate is directly controlled to rotate to adjust the angle of the metal plate, the support plate will interfere with the support platform, and this interference limits the rotation range of the metal plate and the flexibility of the angle adjustment). In this process, the metal plate will be affected by the friction of the support plate, and the accuracy of its angle adjustment cannot be guaranteed, resulting in the metal plate being unable to be accurately aligned to the required angle after changing sides, affecting the accuracy of subsequent shearing.

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-Figure 8 The present invention provides a technical solution: a shearing device for processing metal mechanical parts, comprising a processing table 1 and a shearing mechanism 2 installed on the processing table 1, the upper end of the processing table 1 is slidably connected with a slide frame 4, a telescopic rod 5 for controlling the movement of the slide frame 4 is installed in the processing table 1, a support table 6 is fixedly provided at the upper end of the slide frame 4, a suction cup 7 is embedded in the support table 6, a rotary sleeve 10 penetrating the support table 6 is fixedly provided at the bottom of the suction cup 7, a driving member 1 for controlling the rotation of the rotary sleeve 10 is provided on the slide frame 4, an inner cavity 11 is formed inside the rotary sleeve 10, a plug disc 12 is slidably embedded inside the inner cavity 11, a sleeve 13 fixed to the plug disc 12 is rotatably connected to the upper end of the slide frame 4, and a driving member 2 for controlling the rotation of the sleeve 13 is provided on the slide frame 4.

[0023] The shearing mechanism 2 is a prior art, which uses a crank mechanism or an eccentric mechanism to drive the blade to shear the metal plate extending out of the platform. The telescopic rod 15 is an existing pneumatic or hydraulic telescopic rod. The metal plate is placed on the support platform 6, and the slide frame 4 is driven to move along the processing platform 1 by the telescopic rod 15. When the metal plate extends a corresponding length relative to the platform, the shearing mechanism 2 is controlled to shear the extended part.

[0024] A plurality of air holes are formed on the top of the suction cup 7. After completing the shearing of one side of the metal plate, the sleeve 13 is rotated by controlling the second driving member, so that the suction cup 7 is vertically extended out of the support platform 6 under the action of the transmission member, so that the bottom of the metal plate is separated from the upper end surface of the support platform 6, thereby reducing the friction force when the angle of the metal plate is adjusted. During the lifting process of the suction cup 7, the internal space of the inner cavity 11 increases, resulting in a decrease in the air pressure of the inner cavity 11. At this time, the external atmospheric pressure adsorbs the metal plate on the suction cup 7. This method of using air pressure difference to achieve adsorption can not only firmly fix the metal plate, but also keep it stable during the rotation of the metal plate, avoiding the displacement of the metal plate caused by the loosening of the clamping mechanism. Subsequently, the second driving member controls the rotary sleeve 10 to drive the suction cup 7 to rotate, thereby achieving the angle adjustment of the metal plate.

[0025] Through the air hole on the top of the suction cup 7 and the rotation of the second driving member to control the sleeve 13, the suction cup 7 is extended vertically out of the support platform 6, so that the bottom of the metal plate is separated from the upper end surface of the support platform 6. This process significantly reduces the friction between the metal plate and the support platform 6 when adjusting the angle. In actual operation, the reduction of friction helps to adjust the angle of the metal plate more accurately, avoid displacement deviation caused by friction, and thus improve the shearing accuracy.

[0026] A transmission member is provided in the sleeve 13. When the sleeve 13 rotates, the suction cup 7 moves vertically under the action of the transmission member. A retaining ring 18 rotatably connected to the sliding frame 4 is sleeved on the outer side of the sleeve 13. A hole groove 17 is formed through the side wall of the sleeve 13. A hole groove 2 19 is formed through the side wall of the retaining ring 18. A plug rod 34 slides through the retaining ring 18. A slot is formed on the side wall of the sleeve 13. A compression structure for adjusting the plugging state of the plug rod 34 and the slot is provided on the outer side of the sleeve 13.

[0027] The sleeve 13 allows the inner cavity 11 to communicate with the external space through the hole groove 17 that penetrates it. When the hole groove 17 is aligned with the hole groove 2 19, the inner cavity 11 is connected with the external space, and the suction cup 7 will release the adsorption state of the metal plate. When the insertion rod 34 is in a disengaged state from the slot, as the sleeve 13 rotates, the hole groove 17 and the hole groove 2 19 are staggered, so that when the suction cup 7 is lifted, the internal space of the inner cavity 11 is enlarged, and the metal plate is adsorbed.

[0028] When the support 6 is in the metal plate replacement station, the insertion rod 34 and the slot are in an inserted state. As the sleeve 13 rotates, the retaining ring 18 will be driven to rotate together through the insertion rod 34, so that the hole groove 17 and the hole groove 2 19 are always in an aligned state. At this time, the change of the space of the inner cavity 11 will not affect the adsorption state of the metal plate, which is convenient for the user to replace the metal plate on the support 6.

[0029] A clamping plate 32 is movably provided above the support platform 6, and a linkage is provided above the slide frame 4. When the sleeve 13 rotates, the clamping state of the clamping plate 32 on the metal parts is controlled by the linkage.

[0030] When the suction cup 7 lifts the metal plate upward, the clamping plate 32 will be lifted off the top of the metal plate under the action of the linkage. When the support platform 6 is in the metal plate replacement station, it is convenient for the user to replace the metal plate. When the metal plate is in the shearing station, it is helpful for the suction cup 7 to adjust the angle of the metal plate. When the suction cup 7 is embedded in the support platform 6 downward, the clamping plate 32 will press the metal plate under the action of the linkage. This design ensures that the metal plate remains stable during the shearing process and avoids the reduction of shearing accuracy due to the displacement of the metal plate.

[0031] Specifically, Figure 2 and Figure 5 As shown, the driving member 1 includes a gear ring 3 and a gear 37 rotatably connected to the lower end of the support platform 6, and the gear ring 3 is sleeved on the outer side of the rotary sleeve 10 and slidably connected to the rotary sleeve 10 through a spline. A motor 38 for controlling the rotation of the gear 37 is installed on the slide frame 4. The motor 38 is installed at the side end of the slide frame 4, and its output end controls the rotation of the gear 37 through a bevel gear transmission mechanism.

[0032] The motor 38 serves as a power source. After its output end changes the rotation direction through a bevel gear transmission mechanism, the driving gear 37 rotates. The gear 37 meshes with the gear ring 3. The rotation of the gear 37 drives the gear ring 3 to rotate. The gear ring 3 is slidingly connected to the rotary sleeve 10 through a spline. The rotation of the gear ring 3 is transmitted to the rotary sleeve 10 through the spline, thereby realizing the rotation of the support 6.

[0033] Specifically, Figure 2 and Figure 3 As shown, the transmission member includes a slide rod 8 rotatably connected to the top of the suction cup 7, a sleeve 14 is sleeved on the outer side of the slide rod 8 and fixed to the bottom of the sleeve 13, a protrusion 15 is formed on the inner wall of the sleeve 14, and a slide rail 9 is formed on the side wall of the slide rod 8 to slide with the protrusion 15, a frame rod 16 is fixed on the upper end of the slide frame 4 and passes through the sleeve 13, and the frame rod 16 is slidably connected to the inner side of the slide rod 8 through a spline.

[0034] The slide rail 9 is a spiral structure. When the sleeve 13 rotates, the protrusion 15 fixed on the inner wall of the sleeve 14 will slide along the slide rail 9. The protrusion 15 acts on the inner wall of the spiral structure of the slide rail 9, driving the slide rod 8 to slide vertically along the frame rod 16.

[0035] Specifically, Figure 3-Figure 6 As shown, the compression structure includes a bending frame 33 which is slidably arranged on the outside of the retaining ring 18 and fixed to the insertion rod 34. The outside of the insertion rod 34 is sleeved with a spring 35 which acts on the bending frame 33 outward. A support rod 36 is fixed to the bottom of the bending frame 33. A slideway 39 which cooperates with the sliding of the support rod 36 is formed inside the sliding frame 4.

[0036] When the slide frame 4 moves and drives the metal plate placed on the support 6 to the shearing processing station, the bending frame 33 is in a position away from the retaining ring 18 under the action of the spring 35. At this time, the insertion rod 34 fixed on the bending frame 33 is in a separated state from the slot, so that the sleeve 13 can rotate relative to the retaining ring 18, and the support rod 36 fixed on the bending frame 33 is located in the linear groove of the slide 39, thereby limiting the arbitrary rotation of the retaining ring 18.

[0037] The slideway 39 is composed of an annular groove and a linear groove. The compression structure also includes a slider 40 slidably embedded in the linear groove. The slider 40 is fixed with a cross bar 41 that slides through the slide frame 4. The top of the processing table 1 is fixed with a baffle 42 corresponding to the cross bar 41.

[0038] During the movement and reset of the sliding frame 4, the sliding frame 4 leans against the baffle 42, and the cross bar 41 pushes the support rod 36 from the linear groove into the annular groove through the slider 40 under the push of the baffle 42. At the same time, the insertion rod 34 will be inserted into the slot inside the sleeve 13. When the sleeve 13 rotates, it will drive the retaining ring 18 to rotate synchronously, so that the hole groove 17 and the hole groove 2 19 are always in an aligned state.

[0039] Specifically, Figure 4-Figure 8 As shown, the linkage includes a rotary cylinder 26 rotatably connected to the support platform 6, and a component driving the rotary cylinder 26 to rotate. A vertical rod 30 fixed to a clamping plate 32 is slidably embedded inside the rotary cylinder 26, and a round rod 31 is fixed to the side wall of the vertical rod 30. A slide rail 27 for cooperating with the round rod 31 is formed through the side wall of the rotary cylinder 26; a vertical sleeve 28 is fixed at the upper end of the support platform 6, and a slide groove 29 for cooperating with the round rod 31 is formed in the vertical sleeve 28, and the slide groove 29 is composed of an annular groove and a vertical groove. The slide rail 27 has a spiral structure. When the suction cup 7 is embedded downward in the support platform 6, the rotary drum 26 rotates accordingly. The slide rail 27 pulls the round rod 31, driving the round rod 31 to slide along the annular groove of the slide groove 29 first. During this process, the vertical rod 30 fixed to the round rod 31 will drive the clamping plate 32 to rotate until the round rod 31 slides to the intersection of the annular groove and the vertical groove of the slide groove 29. At this time, the clamping plate 32 rotates ninety degrees. As the rotary drum 26 continues to rotate, the round rod 31 is blocked by the inner wall of the slide groove 29 and will no longer slide in the annular direction. The round rod 31 will move downward along the vertical groove of the slide groove 29 under the action of the spiral structure of the slide rail 27, thereby causing the clamping plate 32 fixed to the vertical rod 30 to press the metal plate downward.

[0040] When the suction cup 7 extends upward from the support 6, the drum 26 rotates, and the spiral structure of the slide rail 27 acts on the round rod 31, driving the round rod 31 to slide along the vertical groove of the slide groove 29, so that the clamping plate 32 is lifted upward from the metal plate. Subsequently, the round rod 31 moves along the annular groove of the slide groove 29 under the action of the inner wall of the slide rail 27, driving the clamping plate 32 to rotate away from the upper area of ​​the metal plate, thereby facilitating the user or an automated robot to pick up and replace the metal plate above the support 6.

[0041] The components that drive the rotating drum 26 to rotate include sprocket 1 22 and sprocket 2 24 rotatably connected to the bottom of the support platform 6, and a coupling that drives sprocket 2 24 to rotate. The outer engaging sleeves of sprocket 1 22 and sprocket 2 24 are provided with a chain 25, and sprocket 2 24 is coaxially fixed with the rotating drum 26.

[0042] When the sprocket wheel 1 22 rotates, the sprocket wheel 2 24 will be driven to rotate synchronously through the meshing action of the chain 25.

[0043] The engaging member driving the second sprocket 24 to rotate includes a support arm 20 fixedly mounted on the side wall of the sleeve 13, a guide rod 21 fixedly mounted on the support arm 20, and a groove 23 for slidingly cooperating with the guide rod 21 is formed in the first sprocket 22.

[0044] When the sleeve 13 rotates, the arm 20 fixed to the sleeve 13 will drive the guide rod 21 to slide along the groove 23, and the sprocket 22 is driven to rotate by the side wall of the guide rod 21 pressing the inner wall of the groove 23.

[0045] Specifically, Figure 2 and Figure 6 As shown, the second driving member is a telescopic rod 43 rotatably mounted on the upper end of the slide frame 4, and the end of the telescopic rod 43 is rotatably connected to the support arm 20. The telescopic rod 43 is an existing hydraulic or pneumatic telescopic rod, and the sleeve 13 fixed to the support arm 20 is driven to rotate by controlling the telescopic state of the telescopic rod 43.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
