Problems solved by technology

If it is necessary to keep one gear selection tooth on each jacquard piece, 16 sets of related molds need to be developed, the cost of the mold is very high and the management cost of the mold is increased during the production process
Therefore, at present, jacquard sheets are supplied in the form of full teeth on the market, but this method has brought a lot of inconvenience to customers. Customers still need to process products by themselves, and the production cost is relatively high.
Customers have a large demand for single-tooth jacquard sheets, but there is no corresponding single-tooth mold to provide direct production to get products

Embodiment 1

[0027] exist figure 1 figure 2 In the shown embodiment 1, a kind of jacquard sheet punching die comprises upper mold base 1, lower mold base 2, punch fixing plate 3 and unloading plate 4, and the center of upper mold base is fixed with an upward protruding Die shank 24, the four corners of lower mold base are provided with parallel upwards protruding and four guide pillars 25 perpendicular to lower mold base, the four corners of upper mold base and guide pillars are correspondingly provided with guide sleeve 26, described guide sleeve and all The guide post forms a sliding pair. The punch fixing plate is a rectangle, and the punch fixing plate is fixed below the upper die seat by the punch backing plate 5, and the punch fixing plate below is correspondingly provided with a die fixing plate 6, and the die fixing plate 6 is fixed. The plate is fixed above the lower die base through the die backing plate 27. The feed side of the punch fixing plate is provided with a horizonta...

Embodiment 2

[0032] exist Figure 5 Image 6 Figure 7 In the shown embodiment 2, the arrangement direction of the square hole punch is inclined to the feeding direction of the mould, and the rest are the same as in the embodiment 1.

[0033] When the jacquard sheet blanking die of the present invention is produced, the material belt 28 through leveling is sent to the initial position of the mold through the servo feeding system, and the slide block of the punch press drives the entire upper mold to move downward, and the unloading plate first contacts the material belt, and Under the action of the unloading spring, the material belt is pressed to ensure the position of the material belt. The upper die continues to move downward, and the punching punch contacts the material belt to complete the punching action. This punching hole is used for subsequent guidance and misfeed detection. , to ensure that the step distance of the material belt is consistent during the transmission process; fo...

Abstract

The invention discloses a punching die for a jacquard sheet, which comprises an upper die base, a lower die base, a punch fixing plate and a discharge plate, the punch fixing plate is fixed below the upper die base through a punch backing plate, The die fixing plate below is correspondingly provided with a die fixing plate, and the middle part of the punch fixing plate is provided with a plurality of square hole punches, and the die fixing plate is correspondingly provided with a square hole die, and the punch The discharge side of the fixed plate is provided with a full-tooth jacquard sheet punch, and the concave mold fixed plate is correspondingly provided with a full-tooth jacquard sheet die; the lower surface of the punch backing plate is provided with a selection groove, and the A selection plate is arranged in the selection groove, and a selection hole for accommodating the square hole punch is arranged on the selection plate. The jacquard sheet punching die of the present invention can complete the production of various jacquard sheets with different needle selection teeth and full-tooth jacquard sheets with one pair of molds, greatly reducing the production cost of single-tooth jacquard sheets.

Description

technical field [0001] The invention belongs to the technical field of knitting needle machinery manufacturing, and in particular relates to a jacquard sheet blanking die. Background technique [0002] The jacquard piece is an important part used in the textile machinery. It cooperates with the reset cam to complete the jacquard in the weaving process. The jacquard piece is usually composed of a whole group of jacquard pieces with different needle selection teeth to cooperate with each other to complete the jacquard action. like Figure 8 Figure 9 As shown in the structure of the jacquard sheet, the jacquard sheet is composed of three parts: the body 29, the foot 30 and the needle selection tooth 31. There are 16 gear selection teeth from A to P on the jacquard sheet, and only one gear selection tooth is reserved for each jacquard sheet. The teeth of the 16 gears with different heights correspond to the paddles on the needle selector device one by one. Jacquard sheets ar...
