Description

Square barrel-shaped alloy tank body forming equipment and system

Technical Field

The invention belongs to the technical field of food packaging can production, and relates to square barrel-shaped alloy can body forming equipment and a system thereof.

Background

A package can for food made of recoverable alloy (such as Al alloy, Mg alloy or Zn alloy) is composed of a can body made of alloy, a top cover film made of alloy and sealed to the open end of said can body, and an aluminium can body with a recess on its top. The food (such as tea and coffee powder) packaged by the tea-leaf packaging bag can be used for a new generation of high-end consumption markets of tea drink/coffee machines and tea drink/coffee capsules, and has the advantages of fresh preservation, simple and convenient operation, quick consumption and no loss of traditional taste. Reduction of production costs to improve production efficiency is a demand for an expanding market.

The existing methods for producing square barrel-shaped alloy tank bodies include punch forming, die-casting forming and spinning forming. The press forming can manufacture parts with thin wall, good rigidity and complex shape at low cost. However, when the can body is subjected to stamping forming, the can body is easy to wrinkle, so that the wall thickness is not uniform, but the outer periphery of the can body cannot be formed into a product with a necking groove or a special-shaped structure. The die-casting forming is used as a special casting process of metal, and has the advantages that high precision can be achieved, the forming efficiency is high, and the square alloy tank body processed by the die-casting forming is good in consistency and high in precision. However, the die-casting process requires a thick wall, and when the alloy can body with a thin-wall structure is formed, poor filling is easily caused, and a welding mark is generated, so that the production defect rate is high, and the production cost is high. The spinning forming technology is called metal spinning forming technology, and can apply force from line to surface at the position of a necking groove of a square barrel-shaped alloy tank body through rotation. Although the necking groove structure of the square packaging can be processed, tea/coffee and the like are taken as fast-selling products, the efficiency of processing the necking groove by numerical control spinning is low, the requirements are difficult to meet, and a product with a special-shaped structure on the periphery can not be formed. In view of the above, the inventors propose the present invention.

The pushing members 212 compress the elastic member when they are away from each other, and approach each other and abut each other to form the molding cavity under the urging of the elastic return of the elastic member when the magnet is powered off.

Referring to fig. 4 and 5, the first driving mechanism 23 includes a first driving assembly 232 and a first transmission assembly 231, and the first transmission assembly 231 is coupled between the first driving assembly 232 and the first forming mechanisms 21 to drive each of the first forming mechanisms 21 to rotate. In the present embodiment, the forming apparatus includes a plurality of first forming mechanisms 21, that is, a plurality of first forming mechanisms 21 are disposed on the first mounting base 6, and the plurality of first forming mechanisms 21 are supported on the first mounting base 6 in an array manner, for example, the plurality of first forming mechanisms 21 are disposed on the first mounting base 6 at intervals along the longitudinal direction and the vertical direction, respectively. The first transmission mechanism is a gear transmission assembly, and the rotation of each first forming mechanism 21 is driven by a driving member (e.g., a motor) and by a multi-stage gear transmission.

The operation principle of the first driving mechanism 23, the first forming mechanism 21 and the first mounting base 6 will be described below with reference to a specific usage.

Referring to fig. 4 and 5, a secondary gear 231C for connecting a first forming mechanism 21 is disposed on the first mounting seat 6, and several secondary gears 231C of the array in the predetermined area are engaged and driven by a same transmission gear 231B, i.e., in this embodiment, the first driving mechanism 23 includes a plurality of transmission gears 231B, each transmission gear 231B is engaged with a same driving gear 231A for power rotation, wherein the driving member is coupled to the driving gear 231A for power supply. In a preferred embodiment, the driving member is a motor, which drives the driving gear 231A to rotate through belt transmission, so as to achieve the purpose of stably transmitting power. By this operation, the purpose of controlling the synchronous rotation of each first forming mechanism 21 is achieved. The first forming mechanism 21 is supported on the first mounting base 6 in a manner of being rotatable relative to the first mounting base 6 through a transmission shaft, and the transmission shaft may be a coupler, a bearing, or the like.

Referring to fig. 1 to 3, the core part 221 has a first feeding passage along an extending direction of the core part 221, and the first molding mechanism 21 includes a stopper 223 having a second feeding passage communicating with the first feeding passage, and the stopper 223 is rotatably coupled to the core part 221 with respect to the core part 221. Wherein the core part 221 is coupled to the stopper 223 through a bearing, and the core part 221 passes through the second molding part 222 and is coupled to the stopper 223 through a bearing. The opposite-pushing component comprises a profile limiting groove 216, wherein the profile limiting groove 216 is formed between the two mold bodies 211, the stopper 223 can abut against the inner peripheral wall of the profile limiting groove 216 when the first molding mechanism 21 rotates, so that the core part 221 has a preset distance from the inner peripheral wall of the molding cavity, and in the rotating process of the first molding mechanism 21, the core part 221 has a preset distance from the inner peripheral wall of the molding cavity to form a square barrel-shaped alloy tank body S with a preset wall thickness. It will be appreciated that the distance is set according to the specifications of the product.

In the implementation of the present invention, the inventors found that, when the stopper 223 abuts against the profiling defining groove 216 of the mold body 211 to form the square barrel-shaped alloy can body S, since the adjacent two walls of the square barrel-shaped alloy can body S are connected by a rounded corner, the core portion 221 is self-rotated by the semi-solid metal during the rotation of the mold body 211, the core portion 221 is affected by the stopper 223, and the trajectory is changed from a curve to a straight line, and the core portion 221 is accelerated in the horizontal direction. Under the action of the acceleration, the forming quality of the inner wall of the square barrel-shaped alloy tank body S close to the round corner part is influenced by the acceleration. For example, if the acceleration is too large, that is, the rotational speed of the die body 211 is too large, which may cause the motion trajectory of the core part 221 relative to the inner circumferential wall of the forming cavity to be straightened by bending or to be shortened by bending, the instantaneous acceleration may increase, which may cause the upper portion of the inner wall of the square barrel-shaped alloy can body S near the rounded corner not to be rolled by the core part 221, thereby causing the wall thickness of the square barrel-shaped alloy can body S at that position to be greater than the predetermined thickness to generate scrap.

In conjunction with fig. 3, 4 and 6, based on the above-described problem, the rotational locus of the core part 221 and its direction are determined in accordance with the rotational direction of the first molding mechanism 21, and the hydraulic cushion device is added on the side to which the acceleration is directed. Specifically, in the present embodiment, a pressing mechanism 7 for pressing the second mounting seat 5 is disposed on the bracket 1, and the pressing mechanism 7 presses the first mounting seat 6 in the longitudinal direction and/or the vertical direction, so that the stopper 223 fixed on the second mounting seat 5 can abut against the inner peripheral wall of the profile-defining groove 216, and the purpose of preventing the core portion 221 from retreating when receiving the reverse thrust of the semi-solid metal liquid is achieved. For example, when the first molding mechanism 21 rotates counterclockwise as viewed in the lateral direction, the core part 221 rotates counterclockwise under the friction force of the semi-solid metal liquid, when the contact position between the molding cavity and the core part 221 is switched between the curve portion and the straight portion, the linear velocity is constantly changed in the straight portion because the rotation speed of the first molding mechanism 21 is constant, further, the acceleration of the switching position between the inner peripheral wall of the molding cavity and the core part 221 is changed between the curve portion and the straight portion, that is, the pressing force of the inner peripheral wall of the molding cavity and the core part 221 is changed, the change of the instantaneous acceleration (that is, the change of the pressing pressure) causes the relative linear velocity of the core part 221 to be increased or decreased instantaneously, taking the example of switching from the curve to the straight portion, because the diameter is the largest at the curve portion, the relative linear velocity of the core part 221 and the first molding mechanism 21 is increased instantaneously while the pressing pressure is increased instantaneously, the core part 221 at this position is displaced in the force-receiving direction with respect to the movement of the semi-solid metal liquid, i.e., resulting in a thicker molded thickness at this position (i.e., at the end of the straight line). The present embodiment provides a predetermined force for the first mounting seat 6 (i.e. each core part 221) by configuring the pressing mechanism 7, so that the core parts 221 do not generate excessive displacement when being stressed, thereby the wall thickness of the square barrel-shaped alloy tank S reaches the required accuracy, and the waste of material is reduced. Meanwhile, the pressing mechanism 7 of the present embodiment can also mold products with different wall thicknesses or different specifications by adjusting the position of the central axis of the core part 221. The pressing mechanism 7 comprises a sliding component and a pressing component, wherein the sliding component is used for enabling the second mounting seat 5 to move longitudinally and/or vertically relative to the support 1. The sliding component includes a slide rail and a sliding component, and preferably, the sliding component is a linear slide rail, and the linear slide rail is a conventional configuration of a processing apparatus, which is not described herein. The pressing member is used for providing a force to the second mounting seat 5 in a longitudinal direction or a vertical direction so that the stopper 223 can abut against the inner peripheral wall of the profiling limiting groove 216. Preferably, the pressure applying member is a hydraulic damper, for example, an AC2050 hydraulic damper.

Referring to fig. 7, the molding apparatus further includes a feeding mechanism 4, wherein the feeding mechanism 4 includes a plurality of feeding pipes 43 respectively communicating with the second feeding channels, a plurality of push-pull seal cylinders 42 correspondingly communicating with the feeding pipes 43 and the feeding grooves 44, and a cylinder 41 communicating with each push-pull seal cylinder 42. A push-pull sealing cylinder 42 corresponds to a second feed channel (i.e., to a core part 221) so that the same amount of semi-solid metal liquid can be injected into the molding cavity. The air cylinder 41 is used for pushing each push-pull sealing cylinder 42 to suck the semi-solid metal liquid through negative pressure, and the semi-solid metal liquid is injected into the forming cavity through the feeding pipe 43 through positive pressure. Wherein, the push-pull sealing cylinder 42 is communicated with the feeding groove 44 through a feeding pipe, and a one-way control valve is arranged on the path of the feeding pipe and the feeding pipe 43 so as to prevent the semi-solid metal from flowing back to the push-pull sealing cylinder 42.

With reference to fig. 8, the molding apparatus includes a pickup mechanism 3, and the pickup mechanism 3 includes a plurality of support plates 33, an adsorption component 34, a vertical slide rail component 31, and a horizontal slide rail component 32. Two of the support plates 33 adjacent in the moving direction are connected together by a rotating shaft in a manner of being able to hinge relatively. The suction members 34 are arranged in a matrix on the support plate 33, wherein each suction member 34 is arranged corresponding to the first molding mechanism 21. The adsorption part 34 includes a material taking part having an adsorption chamber and a negative pressure port opened on the material taking part and communicated with the adsorption chamber. The negative pressure interface can be communicated with a pneumatic pump to work when the square barrel-shaped alloy tank body S enters the adsorption cavity to form negative pressure, so that the square barrel-shaped alloy tank body S is fixed in the adsorption cavity to be taken down. The vertical slide member 31 supports the rotary shaft through a bearing assembly to define the upward movement of each of the support plates 33. The vertical slide rail part 31 includes a vertical slide rail, a vertical slider, and a motor. The horizontal slide rail part 32 supports the vertical slide rail part 31 to drive the support plate 33 to move horizontally, so as to drive the adsorption part 34 to move horizontally, so that the square barrel-shaped alloy tank body S is accommodated in the adsorption chamber.

Wherein the molding apparatus comprises two bearings supported longitudinally on the underside of the support plate 33. The take-out member is directed downward when each of the support plates 33 is supported on the support member to drop the square barrel-shaped alloy can S onto the conveyor belt when the negative pressure is removed.
