Description

Fully automatic breast cup hot pressing forming shearing machine

technical field

The invention relates to a forming device, in particular to an automatic breast cup hot-press forming shearing machine for manufacturing breast cups by using sponge body.

Background technique

The breast cup is the sponge gasket in the bra. The two sides of the breast cup are two approximately spherical curved surfaces, and the edges of the curved surfaces are composed of four arcs that are connected end to end and are not on the same plane.

At present, the production of breast cups generally adopts the breast cup forming machine with the following structure, including the frame, the upper mold table, the lower mold table, the upper mold, the lower mold, the upper heating device, the lower heating device and the cylinder; the upper mold table is fixedly installed on the frame The upper and lower mold tables are installed on the guide pillars of the frame and can slide up and down along the guide pillars; the upper mold is installed on the lower surface of the upper mold table; the lower mold is installed on the upper surface of the lower mold table; the cylinder body of the cylinder is installed on the frame On the upper side, the piston rod of the cylinder is connected with the lower mold table; the upper heating device is installed on the upper mold; the lower heating device is installed on the lower mold. The upper heating device and the lower heating device heat the upper mold and the lower mold respectively. The sponge sheet is placed on the lower mold, and the cylinder drives the lower mold table to rise. The upper mold and the lower mold complete the mold clamping and perform hot pressing to form a breast cup unit.

Because the four arcs that make up the edge of the breast cup are not on the same plane, a cutter is installed around the mold in the usual way. The cutter is fixed perpendicular to a plane for cutting, and the cut shape is often quite different from the original designed shape. Far, can not apply the making of bras. Therefore, at present, after the breast cup is formed, another cutting device is used for cutting, and each breast cup unit is cut on the plane of the sponge sheet around the breast cup unit. For making bras, workers need to use scissors to subtract the folded edges and trim the edges, so the production efficiency is extremely low, a lot of manpower is required, the manufacturing cost is high, and the incision is not smooth enough, and the curvature of the arc is different, which reflects the The quality is poor, and it is uncomfortable to wear after being made into a bra, and it is easy to cause work-related accidents due to the use of scissors for cutting.

Some people try to solve the problem of breast cup shearing by thermal fusing of electrodes. Although this method can cut a breast cup of a specific shape, it is obviously not feasible due to high temperature sintering, which causes the periphery of the breast cup to harden.

Contents of the invention

The technical problem to be solved by the present invention is to provide a full-automatic breast cup hot-press forming shearing machine, which can fully automatically complete the hot-press forming and shearing of the breast cup. The edges are smoother and more natural, improving production efficiency, reducing production costs, and avoiding industrial accidents. The technical scheme adopted is as follows:

Fully automatic breast cup thermoforming shearing machine, including frame, upper mold table, lower mold table, upper mold, lower mold, upper heating device, lower heating device and lifting mechanism, the upper mold table is fixedly installed on the frame, The lower mold table is installed on the guide column of the frame and can slide up and down along the guide column. The upper mold is installed on the lower surface of the upper mold table, and the lower mold is installed on the upper surface of the lower mold table. The lifting mechanism is installed on the frame. The lifting mechanism The output power end of the output power end is connected with the lower mold table, and it is characterized in that: the upper mold includes at least one upper mold unit, correspondingly, the lower mold includes at least one lower mold unit; the upper mold unit has a first protruding outward Curved surface, correspondingly, the lower mold unit has a second curved surface concave inward; it also includes an annular cutter, the annular cutter is located on the second curved surface and arranged along the edge of the second curved surface, and the blade of the annular cutter faces the first curved surface The lifting mechanism is a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected with the lower mold platform; the upper heating device is installed on the upper mold platform; the lower heating device is installed on the lower mold platform.

Both the above-mentioned upper heating device and the lower heating device adopt electric heating.

The upper heating device and the lower heating device installed on the upper mold table and the lower mold table respectively heat the upper mold unit and the lower mold unit through metal heat transfer, so that both the upper mold unit and the lower mold unit reach a suitable temperature; Place the sponge sheet to be processed on the lower mold; by controlling the hydraulic cylinder, the piston rod of the hydraulic cylinder moves upward in the first stroke to drive the lower mold table to rise, the upper mold and the lower mold are molded together, and the sponge sheet is hot-pressed , to form a breast cup unit; and then by controlling the hydraulic cylinder, the piston rod of the hydraulic cylinder moves upward for the second stroke, driving the lower mold table to continue to rise, and the ring cutter presses the first curved surface (that is, the outer wall) of the upper mold unit, according to The edge contour of the lower mold unit cuts the sponge sheet, cuts out each breast cup unit, and completes the thermoforming and cutting of the breast cup automatically. Since the ring cutter is set along the edge contour of the lower mold unit and is on the second curved surface of the lower mold unit, the breast cup unit cut out is the shape of the originally designed breast cup, without further manual trimming, greatly Improve production efficiency, save manpower, reduce production costs, and avoid industrial accidents; since the blade of the ring cutter faces the first curved surface of the upper mold unit, when cutting in the second stroke, the ring cutter and the first A surface line contact, and the cutting direction of the ring cutter is basically perpendicular to the cutting surface where the tangent point of the sponge sheet is located, making the cutting force stronger and ensuring continuous and complete cutting; since the lifting mechanism adopts a hydraulic cylinder, on the one hand it ensures The strength of shearing, on the other hand, realizes the two actions of the hydraulic cylinder through control, and performs hot pressing and shearing respectively. During hot pressing, the periphery of the breast cup unit is basically shaped and maintained at a suitable temperature. Based on this Cutting is carried out immediately after the top, and the cutting is easier, which is one of the important factors to ensure the cutting of the sponge sheet, and the edge of the breast cup after cutting is more smooth and natural, which is suitable for making high-quality bras; by setting the upper heating device at On the upper mold table, set the lower heating device on the lower mold table, so that the upper heating device and the lower heating device are separated from the upper mold unit and the lower mold unit respectively. When changing molds of different specifications, only the mold itself needs to be replaced. There is no need to consider the upper heating device and the lower heating device, and it is more convenient to further process the upper mold unit and the lower mold unit, so that the produced breast cup is more perfect.

As a preferred solution of the present invention, it is characterized in that: the annular cutter is integrally formed with the lower mold unit. The ring cutter and the lower mold unit are integrally formed, as long as the ring cutter is processed at the same time as the second curved surface of the lower mold unit, the setting of the ring cutter is quite convenient; more importantly, the ring cutter and the lower The integrated molding of the mold unit can better ensure the accuracy of the cooperation between the ring cutter and the first curved surface, so that the ring cutter can completely make line contact with the first curved surface, so that every point of the cutting position can be cut.

As a further preferred solution of the present invention, it is characterized in that: the second curved surface gradually approaches the first curved surface from the middle to the edge. The second curved surface gradually approaches the first curved surface from the middle to the edge, so that during hot pressing, the space between the lower mold unit and the upper mold unit is gradually thinned, and the periphery of the formed breast cup unit is also gradually thinned. When the breast cup is used to make a bra, the bra and the chest have a more snug feeling and are very comfortable to wear.

As a further preferred solution of the present invention, it is characterized in that: a slope is provided outside the edge of the first curved surface, the blade of the annular cutter corresponds to the edge of the first curved surface, and the inner surface of the annular cutter matches the slope. By setting a slope outside the edge of the first curved surface, and the edge of the circular cutter is facing the edge of the first curved surface, and the inner surface of the circular cutter cooperates with the slope, when the mold is closed, the circular cutter follows the slope The oblique cut makes the thickness of the formed breast cup more reasonable and easier to control, and prevents the phenomenon of bursting at the incision position. When such a breast cup is used to make a bra, the bra and the chest feel more snug, and it is very comfortable to wear.

The present invention can be applicable to the forming and cutting of breast cups of any type and specification.

Compared with the prior art, the present invention has the following advantages: since the annular cutter is arranged along the edge of the second curved surface, and faces the first curved surface, and adopts the hydraulic cylinder as the driving mechanism at the same time, the method of forming first and then cutting can realize Fully automatic hot press forming and cutting of the breast cup, the edge of the breast cup is smoother and more natural, which improves production efficiency, reduces production costs, and avoids industrial accidents.
