Description

Cutting table with press

technical field

The invention relates to a cutting bed with pressing parts.

Background technique

The transformer coil is the core of the transformer, and now the design of the transformer coil basically has paper pads. The paper pads seem simple, but the actual requirements are relatively strict, so the cutting requirements for the paper pads are also strict. Some problems will be encountered more or less in the process of cutting the paper pad. If the paper pad is wide, it will affect the axial height of the coil; if the paper pad is narrow, it will not protect the inside of the coil. Therefore, there are strict requirements on the width tolerance of the pad strip. There is no part on the existing shearing machine to press the cardboard and then cut it. Only the cutting edge of the cardboard is close to the baffle by manual operation. At the moment of cutting, the cardboard is displaced by the cutting force, and the cut out The pass rate of the product is low, and at the same time, the cardboard is deviated, and the offset part of the remaining cardboard needs to be cut off for correction, resulting in waste of materials.

Contents of the invention

The purpose of the present invention is to solve the above problems and provide a cutting bed with pressing parts, add pressing parts, press the cardboard when cutting, avoid the displacement phenomenon of the cardboard due to the cutting force, improve the cutting accuracy, and then improve the quality of the transformer. The quality of paper pads for coils is also conducive to saving material waste.

The technical solution adopted by the present invention to solve the problems of the prior art is: the cutting bed with pressing parts, including the base, the receiving platform arranged on the base, moving up and away from the receiving platform, and moving down to cooperate with the receiving platform The cutting part for cutting and the driving mechanism for driving the cutting part are characterized in that the cutting part is provided with a pressing part, and the lower end of the pressing part is matched with the receiving platform. A pressing piece is added, and the pressing piece moves up and down together with the cutting parts. In the process of pushing the cardboard against the baffle, the cutting part and the pressing piece move up together to leave space for the cardboard to pass through and abut against the baffle. Press the cardboard when cutting to avoid displacement of the cardboard due to the cutting force, so as to achieve the purpose of precise cutting.

As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the cutting part is a cutter or scissors; the pressing piece is arranged on the side of the cutter, or on the side of the upper cutting piece of the scissors. The cutting part here can also be all feasible that reaches cutting, clipping function such as saw blade, and routine is cutter or scissors.

The pressing piece includes a guide sleeve, a pressing rod vertically passing through the guide sleeve, a length adjusting member matched with the upper end of the pressing rod, and a pressing block matched with the lower end of the pressing rod, which are set on the pressing rod and respectively abut against the two ends of the pressing rod. The guide sleeve and the elastic part on the pressing block, the guide sleeve is detachably connected with the cutting part through the connection assembly. In order to adjust the pressure of the pressing piece on the cardboard, the length of the pressing bar extending toward the bearing table can be adjusted according to the thickness of different cardboards through the setting of the elastic part and the length adjusting piece, so as to achieve the purpose of adjusting the pressure.

In order to avoid or reduce damage to the cardboard, a buffer pad is provided at the end of the pressing block near the bearing table.

The buffer pad is a rubber pad.

In order to have a balanced pressure on the cardboard, there are at least two pressing pieces arranged on the same side, and one pressing piece is respectively arranged at both ends of the cutting part.

The drive mechanism is a cam drive mechanism.

The present invention has outstanding substantive features: 1. Additional pressing parts are added to press the cardboard during cutting, avoiding the displacement phenomenon of the cardboard due to the cutting force, improving the cutting accuracy, and further improving the quality of the cardboard strips for transformer coils. 2. In order to adjust the pressure of the pressing part on the cardboard, through the setting of the elastic part and the length adjusting part, the length of the pressing rod extending to the direction of the supporting table can be adjusted according to the thickness of different cardboards, so as to achieve the purpose of adjusting the pressure. 3. There are multiple pressing parts, and at least one pressing part is arranged at both ends of the cutting part, so that the cardboard bears a balanced force.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Embodiment: a cutting bed with pressing parts, as shown in Fig. 1 and Fig. 2, it includes a base 1, a receiving platform 2 arranged on the base 1, moving up away from the cardboard receiving platform, moving down and receiving The table cooperates with the cutting part 3 for cutting action, the driving mechanism 4 for driving the cutting part, and the pressing part 5 (such as pressing claw) fixed on the cutting part. The driving mechanism can be a cam driving mechanism, and of course other types of driving mechanisms that can drive the cutting parts to move up and down can also be used.

As shown in FIG. 2 , the lower end of the pressing piece 5 cooperates with the receiving platform 2 .

As shown in Figure 3, the pressure piece 5 includes a guide sleeve 51, a pressure rod 52 vertically passing through the guide sleeve, a length adjustment member 53 matched with the upper end of the pressure rod, and a pressure block 54 matched with the lower end of the pressure rod, which is sleeved on the pressure rod. The top and the two ends are respectively against the elastic member 55 (such as a compression spring) on the guide sleeve and the pressure block, and the guide sleeve 51 forms a detachable connection with the cutting part through the connection assembly 6 . As shown in FIG. 3 , the length adjusting member 53 is an adjusting nut, and a washer 7 is arranged between it and the guide sleeve.

In a preferred solution, in order to prevent the cardboard from being crushed or indented on the cardboard, a buffer pad 56 is provided on the surface of the pressing block near the cardboard receiving platform. The rubber pad is a special case of the buffer pad, and of course it can also be other elastic materials with elastic deformation ability and automatic reset.

In a further preferred solution, there are at least two pressing pieces, which are arranged on the same side, and one pressing piece is respectively arranged at both ends of the cutting part. As shown in Figure 1, there are two pressing pieces. When there are more than two pressing parts, it is sufficient to achieve uniform distribution or approximately uniform distribution. Refer to Figure 1 for the corresponding view.

When working, the pressing part moves up and down together with the cutting part, and during the process of pushing the cardboard against the baffle (the baffle is set on the base of the shearing machine and located at a certain distance in front of the cardboard supporting table), the cutting part and the pressing part Move the pieces up together to leave room for the cardboard to pass through against the fence. Press the cardboard when cutting to avoid displacement of the cardboard due to the cutting force, so as to achieve the purpose of precise cutting.
