Its principle can be explained as heating and softening a flat plastic hard sheet, then vacuuming it to the mold surface, and then molding it after cooling, so as to make a product of the desired shape.

[0003] The existing patent number CN201920788334.8 is called a vacuum forming cutting machine and a straight punching machine. It discloses an upper fixed plate, an upper pressing plate mounted on the upper fixed plate, a lower fixed plate, and a lower pressing plate mounted on the lower fixed plate. The lower fixed plate is fixed with a column that passes through the lower pressing plate, the upper pressing plate, and the upper fixed plate in sequence; the upper pressing plate and the upper fixed plate, and the lower pressing plate and the lower fixed plate are movably connected by an upper connecting rod assembly and a lower connecting rod assembly respectively, and the upper connecting rod assembly and the lower connecting rod assembly are connected by an eccentric rotating rod and a driving rod. Mechanism connection; the eccentric rotating rod is driven by the driving mechanism, and the eccentric rotating rod drives the upper connecting rod assembly and the lower connecting rod assembly respectively, so that the upper pressure plate and the lower pressure plate perform opposite movements to complete the punching. The above technical scheme does not provide a tooling for limiting the workpiece to be cut. The conventional workpiece to be cut is held by the staff and then cut with the punching tool. The cutting accuracy is low and the uneven incision affects the normal use in the later stage. Therefore, it is particularly important to design a blister forming cutting and punching machine to solve the above technical problems. Utility Model Content

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] The utility model discloses a vacuum forming cutting and punching machine, comprising a base 1, wherein the base 1 is fixedly connected to a base 102 through a connecting rod 101, a mounting plate 2 is fixedly connected to the top of the base 102, the base 102 and the mounting plate 2 are connected through a guide column 201, an oil cylinder 3 is fixedly connected to the mounting plate 2, a slide rod 301 is slidably connected in the oil cylinder 3, a rectangular plate 302 is fixedly connected to the end of the slide rod 301, both sides of the rectangular plate 302 are fixedly connected to a sliding sleeve 303, the sliding sleeve 303 is slidably connected to the guide column 201, and the A cutter 304 is installed below the rectangular plate 302 through fasteners. A workpiece 4 is movably connected to the base 102. The workpiece 4 is movably connected at the central position of the base 102. A leakage groove 5 is provided on the base 102. The joint between the workpieces 4 is located directly above the leakage groove 5, which is convenient for the subsequent cutting work. The width of the cutter 304 is smaller than the width of the leakage groove 5, which is convenient for the cutter 304 to pass through the leakage groove 5 as a whole. The width of the workpiece 4 is smaller than the width of the leakage groove 5, which is convenient for the waste material after cutting to fall from the leakage groove 5.

[0019] When the blister forming cutting and punching machine is actually used, the workpiece 4 to be cut is placed on the base 102. At this time, the four groups of electric cylinders 601 cooperate with the telescopic rod 602 to drive the limit plate 6 to move upward and downward, so that the limit plate 6 abuts against the surface of the workpiece 4. The staff then manually corrects it so that the joint of the adjacent workpieces 4 to be cut is located directly above the leakage groove 5. Before the cutting work is carried out, the staff manually installs the cutter 304 on the rectangular plate 302 with the fasteners, and then the staff controls the driving cylinder 3 to start working, driving the rectangular plate 302 at the end of the slide rod 301 to move from top to bottom until the cutter 304 passes through the leakage groove 5 and cuts off the joint between the two adjacent workpieces. Then the cylinder 3 is reset under the control of the staff, and the waste formed after cutting falls from the leakage groove 5 into the collection box 603. The above completes the cutting work once, and through A base 1 is installed at the bottom of the base 102 in cooperation with the connecting rod 101, and a telescopic rod 602 is slidably arranged at the bottom of the base 1. The telescopic rod 602 cooperates with the limit plate 6 to complete the limit and fixation of the workpiece 4 on the base 102, and then the slide bar 301 is driven from top to bottom under the action of the oil cylinder 3 until the cutter 304 completes the cutting of the two connected workpieces 4. Compared with the conventional case where no limit mechanism is set, the technical solution adopted by the utility model enables the workpiece 4 to have a stable limit on the base 1, which is convenient for cutting. The overall structure of the blister forming cutting and punching machine is compact and the space layout is reasonable. It is easy for the staff to install and maintain. The overall structure has good stability and is not prone to failure, which reduces the later maintenance cost. The limit plate 6 is driven by the electric cylinder 601 and the telescopic rod 602 to complete the installation and limit of the limit plate 6 on the base 102.

[0020] like Figure 1-2 As shown, the limit plates 6 are symmetrically distributed above the base 102, the bottom of the base 102 is fixedly connected to an electric cylinder 601, a telescopic rod 602 is movably connected in the electric cylinder 601, the end of the telescopic rod 602 is fixedly connected to the limit plate 6, the cross section of the limit plate 6 is L-shaped, a collection box 603 is installed on the base 1, and the collection box 603 is located between the adjacent connecting rods 101,

[0021] The effect achieved by the entire embodiment 1 is that, during use, the telescopic rod 602 slidably connected in the electric cylinder 601 is used to complete the up and down sliding of the telescopic rod 602 fixedly connected to the end of the limit plate 6 in the base 102. Since the cross-section of the limit plate 6 is L-shaped, the workpiece 4 under the limit plate 6 is stably fixed on the base 102. Through the structural design of the collection box 603, the waste formed after cutting can be collected in time.

[0022] Working principle: Place the workpiece to be cut on the base. At this time, four groups of electric cylinders cooperate with the telescopic rod to drive the limit plate to move upward and downward, so that the limit plate abuts against the surface of the workpiece, and the staff manually corrects it so that the joints of adjacent workpieces to be cut are located directly above the leakage trough. Before the cutting work begins, the staff manually installs the cutter on the rectangular plate with fasteners, and then the staff controls the drive cylinder to start working, driving the rectangular plate at the end of the slide rod to move from top to bottom until the cutter passes through the leakage trough and cuts off the joint between the two adjacent workpieces. Then the cylinder is reset under the control of the staff, and the waste formed after cutting falls from the leakage trough into the collection box. The above completes one cutting work.
