Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hopper cold extrusion forming, and particularly relates to a hopper cold extrusion precision forming processing equipment. BACKGROUND

[0002] The hopper is a common material storage and conveying equipment, which is widely used in industrial production, agriculture, construction, logistics and other fields. Its main function is to temporarily store materials and convey them to the next process or equipment through a specific way (such as gravity, mechanical force, etc.). The design and structure of the hopper are different due to the differences in application scenarios and material properties.

[0003] In the production process of hopper cold extrusion forming, after the work personnel complete the feeding operation of the raw material, the raw material surface needs to be brushed with drawing oil. The drawing oil can form a lubricating film between the raw material and the mold, effectively reducing the friction coefficient and reducing the resistance in the deformation process, thereby playing a role in protecting the raw material and preventing tearing. However, in the existing production technology, the brushing of drawing oil mainly depends on manual operation, and the work personnel need to hold a brush or a spray gun to brush the raw material. This manual brushing method has many disadvantages. On the one hand, the manual operation speed is limited, and it is difficult to meet the efficient production rhythm in large-scale production, resulting in low overall production efficiency. On the other hand, manual brushing cannot guarantee the uniformity of the distribution of drawing oil on the surface of the raw material, and it is easy to cause over-thickness or under-thickness of the drawing oil. Over-thickness not only causes waste of drawing oil, but also may affect the quality of subsequent processing. Under-thickness cannot effectively play the lubricating role, and there is still a risk of tearing of the raw material.

[0004] Therefore, it is necessary to design a hopper cold extrusion precision forming processing equipment to solve the above problems. SUMMARY

[0012] As a preferred technical solution of the present application, the outer wall of the reel is provided with a winding groove corresponding to the liquid supply pipe, and the inner side of the oil storage barrel is provided with stretched oil.

[0013] As a preferred technical scheme of the present application, the guide structure comprises a guide opening formed in the top surface of the winding box, the inner wall of the guide opening is rotatably provided with a transmission screw rod, the inner wall of the guide opening is slidably provided with a guide plate, the guide plate is screwed with the transmission screw rod, the top surface of the guide plate is provided with a through hole corresponding to the liquid supply pipe, and the transmission screw rod is drivingly connected with the winding reel through a driven wheel and a synchronous belt.

[0020] Referring to Figures 1-9 A cold extrusion precision forming processing equipment of a hopper, comprising a base 11 and an extrusion seat 12 arranged on the upper part of the base 11, a die seat 13 fixedly installed on the top surface of the base 11, a support assembly corresponding to the die seat 13 arranged on the top surface of the base 11, a spraying assembly for spraying drawing oil on raw materials arranged on the support assembly, and a pump oil assembly for supplying oil to the spraying assembly arranged on the side surface of the base 11; After the raw material is placed on the mold base 13 and the stretching oil spraying is completed, the staff can open the extrusion base 12 and perform cold extrusion forming treatment on the raw material by the mode that the mold groove is attached to the mold base 13 through the bottom surface.

[0021] With reference to Figure 2 and Figure 3 , the supporting assembly comprises two supporting plates 23 symmetrically arranged on the top surface of the base 11, one end of the opposite side surface of the two supporting plates 23 is fixedly installed with a guide rod 24, and the other end is rotatably installed with a drive screw 25, the supporting assembly further comprises four mounting holes 21 symmetrically arranged on the top surface of the base 11, the inner wall of the four mounting holes 21 is fixedly installed with an elastic telescopic rod 22, the two supporting plates 23 are respectively fixedly connected with the telescopic ends of the two elastic telescopic rods 22 on the two sides, the top surface of the two supporting plates 23 is symmetrically fixedly installed with two pressing rods 26, the side surface of the base 11 is fixedly installed with an elastic supporting rod 27, the telescopic end of the elastic supporting rod 27 is fixedly installed with a servo motor 28, and the output end of the servo motor 28 is fixedly connected with the end of the drive screw 25, and the servo motor 28 is located on the outside of the top surface of the base 11; The servo motor 28 can be turned on to drive the drive screw 25 to rotate, one of the two sleeves 31 is screwed with the drive screw 25, and the other is slidably connected with the guide rod 24, so that when the drive screw 25 rotates, the whole formed by the two sleeves 31 and the supporting rod 32 can be driven to reciprocatingly slide along the guide rod 24; when the extrusion base 12 moves downward, the supporting plate 23 can be pressed by the pressing rod 26, so that the elastic telescopic rod 22 is shortened to make room for the extrusion base 12, and at the same time, when the mold groove and the mold base 13 are extruded and positioned, the extrusion base 12 is at a certain distance from the base 11, at this time, the atomizing nozzle 35 and the like can be located in this distance, which will not affect the use of the mold base 13.

[0022] With reference to Figures 3-5 , the spraying and brushing assembly comprises the sleeves 31 respectively sleeved on the outer walls of the guide rod 24 and the drive screw 25, the supporting rod 32 is fixedly installed between the two sleeves 31, the supporting rod 32 is sleeved with a plurality of atomizing nozzles 35, the spraying and brushing assembly further comprises a plurality of guide rings 33 slidably installed on the outer wall of the supporting rod 32 through the sliding groove and the sliding block, the supporting rod 32 is sleeved with a plurality of threaded rings 34 corresponding to the guide rings 33, and the threaded rings 34 are rotatably connected with the guide rings 33, the outer wall of the supporting rod 32 is provided with threads screwed with the threaded rings 34, the atomizing nozzles 35 are fixedly installed on the outer wall of the guide rings 33, the atomizing nozzles 35 are provided with control valves 36, the outer walls of the two sleeves 31 are fixedly installed with fixed pipes 37, the plurality of atomizing nozzles 35 are communicated with the fixed pipes 37 through the communication pipes 38, and the communication pipes 38 are provided as hoses; The worker can place the raw material of the cold extrusion forming hopper on the die seat 13 on the top surface of the base 11, and then adjust the atomizing nozzle 35 according to the size of the raw material. When adjusting, the threaded ring 34 can be rotated. The threaded ring 34 is screwed with the support rod 32 and the end is rotationally connected with the guide ring 33. At the same time, the guide ring 33 and the support rod 32 are connected through the sliding groove and the sliding block. Therefore, when the threaded ring 34 rotates, it can drive the guide ring 33 to slide along the support rod 32, so that the position of the atomizing nozzle 35 is adjusted. The plurality of atomizing nozzles 35 on the support rod 32 can be distributed according to the size of the raw material. At the same time, the atomizing nozzles 35 that are not used can be closed through the control valve 36. The other atomizing nozzles 35 can be used normally. The working principle of the control valve 36 and the connection mode between the atomizing nozzle 35 are existing mature technologies, and will not be described in detail here.

[0023] With reference to Figure 1 , Figure 6 , Figure 7 and Figure 9 , the pump oil assembly comprises a winding box 41 fixedly installed on the side surface of the base 11. The side surface of the base 11 at the side edge position of the winding box 41 is fixedly installed with a pump body 42. The side surface of the base 11 at the side edge position of the pump body 42 is fixedly installed with an oil storage barrel 43. The inner side of the oil storage barrel 43 is provided with stretch oil. The liquid inlet end of the pump body 42 is in communication with the oil storage barrel 43 through a conduit. The inner side of the winding box 41 is rotationally installed with a reel 44. The outer wall of the reel 44 is provided with a liquid supply pipe 46. One end of the liquid supply pipe 46 is fixedly connected with the liquid outlet end of the pump body 42, and the other end is in communication with the fixed pipe 37. The top surface of the winding box 41 is provided with a guide structure corresponding to the liquid supply pipe 46. The outer wall of the reel 44 is provided with a winding groove 45 corresponding to the liquid supply pipe 46. The side surface of the base 11 is rotationally installed with a transmission shaft 61 through a mounting bracket. One end of the transmission shaft 61 is fixedly installed with a driven bevel gear 62. The output end of the servo motor 28 is fixedly sleeved with a driving bevel gear 63 engaged with the driven bevel gear 62. The other end of the transmission shaft 61 is drivingly connected with the reel 44 through a belt pulley and a transmission belt. When the oil tank 43 is filled with the stretching oil, the pump body 42 is opened synchronously, so that the stretching oil in the oil tank 43 can be guided into the pump body 42 through the conduit, and then into the fixed pipe 37 through the liquid outlet of the pump body 42 and the liquid supply pipe 46, and then into each opened atomizing nozzle 35 through the communication pipe 38, so that the stretching oil can be uniformly sprayed on the surface of the raw material, so as to cold extrude the raw material into a hopper. When the two surfaces of the raw material need to be sprayed, the raw material needs to be turned over by the worker and the above steps are repeated to realize double-sided spraying. When the servo motor 28 is opened to drive the support rod 32 to move, the fixed pipe 37 on the sleeve ring 31 also needs to move with it. During the whole movement process, the liquid supply pipe 46 needs to be wound and unwound to meet the movement requirement of the fixed pipe 37. When the servo motor 28 is opened, the driving bevel gear 63 can be driven to rotate, the driving bevel gear 63 is engaged with the driven bevel gear 62, and then the driven bevel gear 62 and the transmission shaft 61 can be driven to rotate. The end of the transmission shaft 61 is connected with the reel 44 through the belt pulley and the transmission belt, so that the reel 44 can be driven to rotate. When the reel 44 rotates, the liquid supply pipe 46 can be unwound, so as to meet the requirement of the movement of the fixed pipe 37 away from the servo motor 28. When the atomizing nozzle 35 moves reversely, the servo motor 28 is reversed, the reel 44 is reversed to wind the liquid supply pipe 46. The winding mode of the liquid supply pipe 46 on the reel 44 can refer to the winding mode and principle of the fire-fighting pipe in the fire-fighting box. One end is fixed and the other end can be wound and unwound at will.

[0024] With reference to Figure 7 and Figure 8 , the guide structure comprises a guide opening 51 formed in the top surface of the winding box 41, a transmission screw 52 rotatably installed on the inner wall of the guide opening 51, and a guide plate 53 slidably installed on the inner wall of the guide opening 51 and screwed with the transmission screw 52. A through hole 54 corresponding to the liquid supply pipe 46 is formed in the top surface of the guide plate 53, and the diameter of the through hole 54 is at least greater than the diameter of the liquid supply pipe 46. The transmission screw 52 is connected with the reel 44 through a driven wheel and a synchronous belt. During the winding and unwinding process of the liquid supply pipe 46 by the reel 44, the transmission screw 52 can be driven to rotate through the driven wheel and the synchronous belt. Since the guide plate 53 is screwed with the transmission screw 52 and slidably connected with the inner wall of the guide opening 51, the guide plate 53 can be driven to slide along the guide opening 51 when the transmission screw 52 rotates, so as to guide the winding and unwinding of the liquid supply pipe 46, and the liquid supply pipe 46 can be accurately wound and unwound along the winding groove 45. The pipe body of the liquid supply pipe 46 has a certain supporting force in the radial direction, so that it can normally guide liquid when it is in the winding groove 45, and the normal supply of the stretching oil during the movement of the atomizing nozzle 35 is ensured.

[0025] The specific working principle of the present application is as follows: In use, first, the staff can put the raw material of the cold extrusion forming hopper on the mold base 13 on the top surface of the base 11, and then adjust the atomizing nozzle 35 according to the size of the raw material. When adjusting, the threaded ring 34 can be rotated, the threaded ring 34 is screwed with the support rod 32 and the end is rotationally connected with the guide ring 33, and the guide ring 33 is slidingly connected with the support rod 32 through the sliding groove and the sliding block. Therefore, when the threaded ring 34 rotates, it can drive the guide ring 33 to slide along the support rod 32, so that the position of the atomizing nozzle 35 is adjusted, and a plurality of atomizing nozzles 35 on the support rod 32 can be distributed according to the size of the raw material. At the same time, for the atomizing nozzles 35 not in use, they can be closed through the control valve 36, and the other atomizing nozzles 35 can be used normally. The working principle of the control valve 36 and the connection mode between the control valve 36 and the atomizing nozzle 35 are both mature technologies, and will not be described in detail here. Then the servo motor 28 can be started to drive the drive screw 25 to rotate. One of the two collars 31 is screwed with the drive screw 25, and the other is slidingly connected with the guide rod 24. Therefore, when the drive screw 25 rotates, it can drive the whole composed of the two collars 31 and the support rod 32 to reciprocally slide along the guide rod 24. In this process, since the oil tank 43 is filled with stretching oil, the pump body 42 is opened at the same time, so that the stretching oil in the oil tank 43 can be guided into the pump body 42 through the conduit, and then into the fixed pipe 37 through the liquid outlet of the pump body 42 and the liquid supply pipe 46, and then into each opened atomizing nozzle 35 through the communication pipe 38 to be sprayed out, so that the stretching oil can be uniformly sprayed on the surface of the raw material to cold extrude the raw material into a hopper. If it is necessary to spray both sides of the raw material, the staff needs to turn over the raw material and repeat the above steps to realize double-sided spraying. When the servo motor 28 is started to drive the support rod 32 to move, the fixed pipe 37 on the collar 31 also needs to move with it. During the whole movement process, the liquid supply pipe 46 needs to be wound and unwound to meet the movement requirement of the fixed pipe 37. When the servo motor 28 is started, it can drive the drive bevel gear 63 to rotate, the drive bevel gear 63 is engaged with the driven bevel gear 62, and then the driven bevel gear 62 and the transmission shaft 61 can be rotated. The end of the transmission shaft 61 is transmissionally connected with the reel 44 through the belt pulley and the transmission belt, so that the reel 44 can be rotated. When the reel 44 rotates, the liquid supply pipe 46 can be unwound to meet the requirement of the movement of the fixed pipe 37 away from the servo motor 28. When the atomizing nozzle 35 moves in the opposite direction, the servo motor 28 is reversed to drive the reel 44 to reverse to wind the liquid supply pipe 46. The winding mode of the liquid supply pipe 46 on the reel 44 can refer to the winding mode and principle of the fire-fighting pipe in the fire-fighting box, which is fixed at one end and can be wound and unwound at the other end. In the process of winding the reel 44 to the supply pipe 46, the driven wheel, the synchronous belt driven transmission screw 52 can be rotated, and because the guide plate 53 is screwed with the transmission screw 52 and is in sliding connection with the inner wall of the guide port 51, the transmission screw 52 can drive the guide plate 53 to slide along the guide port 51 when it rotates, thereby guiding the winding and unwinding of the supply pipe 46, so that the supply pipe 46 can be precisely wound along the winding groove 45, and the pipe body of the supply pipe 46 has a certain supporting force in the radial direction, so that it can be normally guided when it is in the winding groove 45, ensuring the normal supply of the drawing oil during the movement of the atomizing nozzle 35; after the drawing oil spraying is completed, the operator can open the extrusion seat 12 and cold extrude the raw material by the mode of the mold groove and the mold seat 13 adhering to the bottom surface, and when the extrusion seat 12 moves downward, the pressure rod 26 can press the support plate 23, so that the elastic telescopic rod 22 shortens to make way for the extrusion seat 12, and at the same time, when the mold groove and the mold seat 13 are extruded in place, the extrusion seat 12 is a certain distance away from the base 11, at this time, the atomizing nozzle 35 can be located in this distance, which will not affect the use of the mold seat 13, and when the elastic telescopic rod 22 shortens, the elastic supporting rod 27 synchronously shortens, and the transmission shaft 61 is driven to elongate, so that the normal transmission of the transmission shaft 61 is not affected.

[0026] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
